NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 – Summary of Significant Accounting Policies 

 

The accounting and financial reporting policies of Umpqua Holdings Corporation conform to accounting principles generally accepted in the United States of America ("GAAP"). All references in this report to "Umpqua," "we," "our," "us," the "Company" or similar references mean Umpqua Holdings Corporation and include our consolidated subsidiaries where the context so requires. References to "Bank" refer to our subsidiary Umpqua Bank, an Oregon state-chartered commercial bank, and references to "Umpqua Investments" refer to our subsidiary Umpqua Investments, Inc., a registered broker-dealer and investment adviser. The Bank also has a wholly-owned subsidiary, Financial Pacific Leasing, Inc. ("FinPac"), a commercial equipment leasing company. The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.  All inter-company balances and transactions have been eliminated. The condensed consolidated financial statements have not been audited. A more detailed description of the Company's accounting policies is included in the 2019 Annual Report filed on Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2019 Annual Report filed on Form 10-K. 

The results for interim periods are not necessarily indicative of results for the full year or any other interim period. As of September 30, 2020, the impact of the novel coronavirus ("COVID-19") continues to unfold and many of the Company's estimates and assumptions require increased judgment and carry a higher degree of variability and volatility, including the provision for credit losses which has been materially impacted. The Company is unable to fully predict the impact that COVID-19 will have on its financial position and results of operations due to numerous uncertainties and will continue to assess the potential impacts on its financial position and results of operations. As events continue to evolve and additional information becomes available, estimates may change materially in future periods.

In preparing these condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to September 30, 2020 for potential recognition or disclosure. In management's opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. Certain reclassifications of prior period amounts have been made to conform to current classifications.

Application of new accounting guidance

In June 2016, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments —Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL" or "ASC 326"). CECL is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. ASC 326 requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, ASC 326 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration.

The adoption date for the Company was January 1, 2020. The guidance was applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at January 1, 2020. However, certain provisions of the guidance are only required to be applied on a prospective basis.

The Bank has elected to not include accrued interest when determining the amortized cost basis of an asset. Instead, the amortized cost basis of an asset is the combination of the balance, deferred fees and costs, and premium or discount. In addition, the Bank has elected to continue to present accrued interest as part of Other Assets on the consolidated balance sheets. The Bank has calculated an allowance for credit losses on accrued interest that is included with the accrued interest balance. The policies related to income recognition on non-accrual loans are outlined below.

Table of Contents

Upon adoption of CECL, the Company did not reassess whether loans previously accounted for as purchased credit impaired ("PCI") met the definition of a Purchased Credit-Deteriorated ("PCD") loan and therefore accounts for all such assets as PCD. The Company has elected not to retain the PCI pools previously established. Instead, the loans will now be included within the appropriate class of financing receivables which have been established based on shared risk characteristics. Changes to the allowance after adoption are recorded through provision expense.

Based on the Bank's portfolio composition as of January 1, 2020, and the economic environment at that time, management recorded an initial estimate of the allowance for credit losses ("ACL") under CECL, which includes the allowance for credit losses on loans and leases ("ACLLL") of $207.6 million and the reserve for unfunded commitments ("RUC") of $8.3 million. The implementation of CECL resulted in a cumulative effect of an accounting change adjustment to retained earnings of $40.2 million.

The Company analyzed the portfolio segments and classes of financing receivables based on the implementation of CECL. There were no necessary changes in the portfolio segments or classes of financing receivables. The increase in the allowance by portfolio segment was as follows:

			December 31, 2019												January 1, 2020

Due to the significance of the implementation of CECL on the Company, the following significant accounting policies have been updated from the policies described in the 2019 Annual Report filed on Form 10-K.

Allowance for Credit Losses Policy- The Bank has established an Allowance for Credit Loss Committee, which is responsible for, among other things, regularly reviewing the ACL methodology, including allowance levels and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The Bank's Audit and Compliance Committee provides board oversight of the ACL process and reviews and approves the ACL methodology on a quarterly basis. CECL is not prescriptive in the methodology used to determine the expected credit loss estimate. Instead, management has flexibility in selecting the methodology. The expected credit losses must be estimated over a financial asset's contractual term, adjusted for prepayments utilizing quantitative and qualitative factors. There are also specific considerations for PCD, Troubled Debt Restructured ("TDR"), and Collateral Dependent Loans ("CDL").

The estimate of current expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms, and differences in economic conditions – both current conditions and reasonable and supportable forecasts. When the Company is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it has estimated expected credit losses for the remaining life using an approach that reverts to historical credit loss information for the longer-term portion of the asset's life.

The Company utilizes complex models to obtain reasonable and supportable forecasts; most of the models calculate two predictive metrics: the probability of default ("PD") and loss given default ("LGD"). The PD measures the probability that a loan will default within a given time horizon and primarily measures the adequacy of the debtor's cash flow as the primary source of repayment of the loan or lease. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral.

The combination of the current expected credit loss, PCD, CDL, TDR, and the RUC components represent the ACL. Management believes that the ACL was adequate as of September 30, 2020. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could possibly result in additional charges to the provision for credit losses.

Acquired Loans and Leases- Loans and leases purchased without more-than-insignificant credit deterioration, are recorded at their fair value at the acquisition date. However, loans and leases purchased with more-than-insignificant credit deterioration will be recorded with their applicable allowance for credit loss to determine the amortized cost basis.

Originated Loans and Leases- Loans are stated at the amount of unpaid principal, net of unearned income and any deferred fees or costs. All discounts and premiums are recognized over the contractual life of the loan as yield adjustments. Leases are recorded at the amount of minimum future lease payments receivable and estimated residual value of the leased equipment, net of unearned income and any deferred fees. Initial direct costs related to lease originations are deferred as part of the investment in direct financing leases and amortized over their term using the effective interest method. Unearned lease income is amortized over the term using the effective interest method.

Income Recognition on Non-Accrual Loans- Loans are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a commercial or commercial real estate loan is past due beyond its maturity or principal or interest payment due date by 90 days or more, unless such loans are well-secured and in the process of collection. Loans that are less than 90 days past due may also be classified as non-accrual if repayment in full of principal and/or interest is in doubt.

Generally, when a loan is classified as non-accrual, all uncollected accrued interest is reversed from interest income and the accrual of interest income is terminated. In addition, any cash payments subsequently received are applied as a reduction of principal outstanding. In cases where the future collectability of the principal balance in full is expected, interest income may be recognized on a cash basis. A loan may be restored to accrual status when the borrower's financial condition improves so that full collection of future contractual payments is considered likely. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will typically not occur until the borrower demonstrates repayment ability over a period of not less than six months.

Collateral Dependent Loans and Troubled Debt Restructurings- A loan or lease is considered collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. The Company's classification of CDLs includes: non-homogeneous non-accrual loans and leases; non-homogeneous loans determined by individual credit review; homogeneous non-accrual leases and equipment finance agreements; and homogeneous real estate secured loans that have been charged down to net realizable value or the government guaranteed balance. Except for homogeneous leases and equipment finance agreements, the expected credit losses for CDLs will be measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. The Company may also use the loan's observable market price, if available. If the value of the CDL is determined to be less than the recorded amount of the loan, a charge-off will be taken. To determine the expected credit loss for homogeneous leases or equipment finance agreements, the LGD calculated by the CECL model will be utilized. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is fully charged-off.

Loans are reported as TDR loans when, due to borrower financial difficulties, the Bank grants a concession it would not otherwise be willing to offer for a loan. Once a loan has been classified as a TDR, it continues in the classification until it has paid in full or it has demonstrated six months of payment performance and was determined to have been modified at a market rate terms. TDRs, including reasonably expected TDRs, are individually recognized and measured for expected credit loss in one of two ways: when a TDR meets the definition of a CDL, it is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable; otherwise, a discounted cash flow analysis is utilized to measure the expected credit loss for a TDR. The expected cash flow for a TDR is discounted based on the pre-modification rate and the expected remaining life.

In March 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was passed, which, among other things, provided relief for Banks related to loan modifications for accounting purposes. Specifically, section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for TDRs. In addition to the CARES Act, bank regulatory agencies issued interagency guidance indicating that a lender could conclude that the modifications under section 4013 of the CARES Act or the interagency guidance are not a TDR if certain criteria are met. The guidance also provides that loans generally will not be adversely classified if the short-term modification is related to COVID-19 relief programs. The Company has followed the guidance under the CARES Act and the interagency guidance related to these loan modifications. Loans modified under section 4013 of the CARES Act or the interagency guidance generally maintain their pre-COVID-19 delinquency status and are classified as performing loans. If it is deemed the modification is not short-term, not COVID-19 related or the customer does not meet the criteria under the guidance to be scoped out of troubled debt restructuring classification, the Company evaluates the loan modifications under its existing framework which requires modifications that result in a concession without appropriate compensation to a borrower experiencing financial difficulty to be accounted for as a TDR.

Reserve for Unfunded Commitments- A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb expected losses associated with the Bank's commitment to lend funds under existing agreements, such as letters or lines of credit. The RUC calculation utilizes the allowance for credit loss on loans and leases rates, probability of default risk ratings, and utilization rates based on the economic expectations over the contractual life of the commitment. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and adjustments are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on loans and leases. Provisions for unfunded commitment losses are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets.

Investment Securities Available for Sale- Debt securities are classified as available for sale if the Company intends and has the ability to hold those securities for an indefinite period of time, but not necessarily to maturity. Any decision to sell a debt security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned.

Securities available for sale are carried at fair value. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Unrealized holding gains or losses are included in other comprehensive income ("OCI") as a separate component of shareholders' equity, net of tax. When the fair value of an available-for-sale debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. Decreases in fair value attributable to credit loss would be recorded directly to earnings with a corresponding allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves the allowance would be reversed up to a maximum of the previously recorded credit losses. If the Company intends to sell an impaired available-for-sale debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment would be immediately recognized in earnings with no corresponding allowance for credit losses.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. This ASU was issued to improve the effectiveness of disclosures surrounding fair value measurements. The ASU removes numerous disclosures from Topic 820 including: transfers between level 1 and 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation process for level 3 fair value measurements. The ASU also modified and added disclosure requirements in regards to changes in unrealized gains and losses included in other comprehensive income, as well as the range and weighted average of unobservable inputs for level 3 fair value measurements. The Company adopted this ASU as of January 1, 2020, on a retrospective basis except certain provisions of the guidance which are only required to be applied on a prospective basis.

Recent accounting pronouncements 

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. The expedients are in effect from March 12, 2020, through December 31, 2022. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements.

These unrealized losses on the Company's debt securities were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not due to the underlying credit of the issuers. Management monitors the published credit ratings of the Company's debt securities for material rating or outlook changes. Substantially all of the Company's obligations of states and political subdivisions are general obligation issuances. All of the available for sale residential mortgage-backed securities and collateralized mortgage obligations portfolio in an unrealized loss position at September 30, 2020 are issued or guaranteed by government sponsored enterprises. Because the decline in fair value of the Company's debt securities is attributable to changes in interest rates or widening market spreads and not credit quality, these investments do not have an allowance for credit losses at September 30, 2020.

The following table presents the contractual maturities of debt securities at September 30, 2020:

The loan balances above include deferred costs, net of deferred fees, of $19.4 million and $71.9 million as of September 30, 2020 and December 31, 2019, respectively. In response to the COVID-19 crisis, the federal government created the Paycheck Protection Program ("PPP"), sponsored by the Small Business Administration ("SBA"), under the CARES Act. The Bank participated in the PPP to originate SBA loans designated to help businesses maintain their workforce and cover other working capital needs during the COVID-19 pandemic by funding 16,900 loans, totaling $2.0 billion in net loans, which are classified as commercial term loans. Net deferred costs are offset by $51.2 million in PPP loan related fees net of costs, which will be a yield adjustment over the remaining term of these loans. The loans are fully guaranteed by the SBA and the maximum term of the loans is either two or five years; however, the majority of the loan balances are expected to be forgiven by the SBA.

Net loans also include discounts on acquired loans of $20.7 million and $30.2 million as of September 30, 2020 and December 31, 2019, respectively. As of September 30, 2020, loans totaling $12.7 billion were pledged to secure borrowings and available lines of credit. The Company elected to exclude accrued interest receivable from the amortized cost basis of loans disclosed throughout this footnote. Interest accrued on loans totaled $70.9 million and $58.5 million as of September 30, 2020 and December 31, 2019, respectively, and is included in Other Assets.

The Bank, through its commercial equipment leasing subsidiary, FinPac, is a provider of commercial equipment leasing and financing. Direct finance leases are included within the lease and equipment finance segment within the loans and leases, net line item. These leases typically have terms of three to five years and are considered to be direct financing leases. Interest income recognized on these leases was $6.7 million and $20.5 million for the three and nine months ended September 30, 2020, respectively, as compared to $8.1 million and $24.6 million for the three and nine months ended September 30, 2019, respectively.

Note 4 – Allowance for Credit Losses

Allowance for Credit Losses Methodology

The Allowance for Credit Losses is an important element in the Bank's financial statements. In accordance with CECL, the ACL represents management's estimate of lifetime credit losses for assets within its scope, specifically loans and leases and unfunded commitments. To calculate the ACL, management uses models to estimate the PD and LGD for loans utilizing inputs that include forecasted future economic conditions and that are dependent upon specific macroeconomic variables relevant to each of the Bank's loan and lease portfolios. Moody's Analytics, a third party, provided the historical and forward-looking macroeconomic data used in the development of the models used to calculate the ACL.

For ACL calculation purposes, the Bank considered the financial and economic environment at the time of assessment and economic scenarios that differed in the levels of severity and sensitivity to the ACL results. At each measurement date, the Bank selects the scenario that reflects its view of future economic conditions and is determined to be the most probable outcome.

All forecasts are updated for each variable where applicable and incorporated as relevant into the ACL calculation. Actual credit loss results will differ from the estimate of credit losses, either in a strong economy or a recession, as our portfolio will change through time due to growth, risk mitigation actions and other factors. In addition, the scenarios used will differ and change through time as economic conditions change. Economic scenarios might not capture deterioration or improvement in the economy timely enough for the Bank to be able to adequately assess the impact to the ACL.

Select macroeconomic variables are projected over the forecast period, and they could have a material impact in determining the ACL. As the length of the forecast period increases, information about the future becomes less readily available and projections are inherently less certain.

The following is a discussion of the changes in the factors that influenced management's current estimate of expected credit losses. The changes in the ACL estimate for all portfolio segments, during the three and nine months ended September 30, 2020, were primarily related to changes in the economic assumptions. The Bank opted to use Moody's Analytics August consensus economic forecast for estimating the ACL as of September 30, 2020. This scenario is based on Moody's Analytics review of a variety of surveys of baseline forecasts of the U.S. economy. These surveys vary in date of latest vintage, number of updates per year, list of variables forecast, duration of forecast, frequency of data (quarterly or annual), and the number of respondents to a survey. In the preparation of the Moody's Analytics consensus forecast, the focus is on the next three to five years, since that is the most typical duration in the surveyed results. Moody's Analytics approach is to give greater consideration to whatever forecasts were produced most recently, since they will include the most up-to-date historical information, and to those variables for which the number of surveyed responses is largest.

In the consensus scenario selected, the probability that the economy will perform better than this consensus is equal to the probability that it will perform worse and included the following factors:

•U.S. real GDP growth begins to decrease after the strong recovery but continues to be positive over both the short and long-term;

•U.S. unemployment rate average of 10.7% in the third quarter of 2020 and is expected to be 9.3% in the fourth quarter of 2020;

•very strong recovery with sustained growth in the fourth quarter of 2020, and continued slow growth thereafter;

•return to less than 5% unemployment by 2024.

The Bank uses an additional scenario that differs in terms of severity within the variables, both favorable and unfavorable, to assess sensitivity in the ACL results and to inform qualitative adjustments. The Bank selected the Moody's Analytics August S2 scenario for this analysis. In the scenario selected, there is a 75% probability that the economy will perform better, broadly speaking, and a 25% probability that it will perform worse; and the scenario includes the following factors:

•rising business bankruptcies and reduced consumer and business sentiment cause the economy to stall over the next several quarters;

•slow real GDP growth through 2021 with increases thereafter;

•U.S. unemployment rate average of 10.2% in the third quarter of 2020 and is expected to be 10.4% in the fourth quarter of 2020;

•very strong recovery in the current quarter of 2020, with substantially slower growth after the current quarter through the second quarter of 2021, then gradually increasing growth thereafter;

•return to less than 5% unemployment by 2025.

The results using the comparison scenario for sensitivity analysis were reviewed by management, but management believes the consensus scenario better reflects the estimated economic environment.

The ACL is measured on a collective (pool) basis when similar characteristics exist. The Company has selected models at the portfolio level using a risk-based approach, with larger, more complex portfolios having more complex models. Except as noted below, the macroeconomic variables that are inputs to the models are reasonable and supportable over the life of the loans in that they reasonably project the key economic variables in the near term and then converge to a long run equilibrium trend. These models produce reasonable and supportable estimates of loss over the life of the loans as the projected credit losses will also converge to a steady state in line with the variables applied. The Company measures the ACL using the following methods:

Commercial Real Estate ("CRE"): Non-owner occupied commercial real estate, multifamily, and construction loans are analyzed using a model that uses four primary property variables: Net Operating Income ("NOI"), Property Value, Property Type, and Location. For PD estimation, the model simulates potential future paths of NOI given commercial real estate market factors determined from macroeconomic forecasts. Using the resulting expected debt service coverage ratios, together with predicted loan-to-values and other variables, the model estimates PD from the range of conditional possibilities. In addition, the model estimates maturity PD capturing refinance default risk to produce a total PD for the loan. The model estimates LGD, inclusive of principal loss and liquidation expenses, empirically using predicted loan-to-value as well as certain market and other factors. The LGD calculation also includes a separate maturity risk component. The primary economic drivers in the model are GDP Growth, U.S. unemployment rate, and 10-Year Treasury yield. The model produces PD and LGD on a quarter-by-quarter basis for the life of loan.

The owner-occupied commercial real-estate portfolio utilizes a top down macroeconomic model using linear regression. This model produces portfolio level quarterly net charge-off rates for 10 years. The primary economic drivers for this model are the 7-year A vs Aa corporate bond spread and S&P 500 corporate after-tax profits.

Commercial: Non-homogeneous commercial loans and leases and residential development loans are analyzed in a multi-step process. An initial PD is estimated using a model driven by an obligor's selected financial statement ratios, together with cycle-adjusting information based on the obligor's state and industry. An initial LGD is derived separately based on collateral type using collateral value and a haircut to reflect the loss in liquidation. Another model then applies an auto-regression technique to the initial PD and LGD metrics to estimate the PD and LGD curves according to the macroeconomic scenario over a one-year reasonable and supportable forecast. The primary economic drivers in the model are the S&P 500 Stock Price Index, S&P 500 Market Volatility Index, U.S. unemployment rate, as well as appropriate yield curves and credit spreads. This model utilizes output reversion methodology, which, after one year, reverts on a straight-line basis over two years to long-term PD estimated using financial statement ratios of each obligor.

The model for the homogeneous lease and equipment finance agreement portfolio uses lease and equipment finance agreement information, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD values. The PD calculation is based on survival analysis while LGD is calculated using a two-step regression. The model calculates LGD using an estimate of the probability that a defaulted lease or equipment finance agreement will have a loss, and an estimate of the loss amount. The primary economic drivers for the model are GDP, U.S. unemployment rate, and a home price growth index. The model produces PD and LGD curves at the lease level for each month in the forecast horizon.

Residential: The models for residential real estate and Home Equity Lines of Credit ("HELOC") utilize loan level variables, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD. The U.S. unemployment rate and home price growth rate indexes are primary economic drivers in both the residential real estate and HELOC models. In addition, the prime rate is also a primary driver in the HELOC model. The models focus on establishing an empirical relationship between default probabilities and a set of loan-level, borrower, and macroeconomic credit risk drivers. The LGD calculation for residential real estate is based on an estimate of the probability that a defaulted loan will have a loss, and then an estimate of the loss amount. HELOCs utilize the same model using residential real estate LGD values to assign loans to cohorts based on FICO scores and loan age. The model produces PD and LGD curves at the loan level for each quarter in the forecast horizon.

Consumer: Historical net charge-off information as well as economic forecast assumptions are used to project loss rates for the Consumer segment.

All loans and leases that have not been modeled receive a loss rate via an extrapolated rate methodology. The loans and leases receiving an extrapolated rate are typically newly originated loans and leases or loans and leases without the granularity of data necessary to be modeled. Based on the vintage year, credit classification, and reporting category of the modeled loans and leases, a loss factor is calculated and applied to the non-modeled loans and leases.

Along with the quantitative factors produced by the above models, management also considers prepayment speeds and qualitative factors when determining the ACL. The Company uses a prepayment model that forecasts the constant prepayment rates based on institution specific data. Below are the nine qualitative factors considered where applicable:

•Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.

•Changes in national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments.

•Changes in the nature and volume of the portfolio and in the terms of loans and leases.

•Changes in the experience, ability, and depth of lending management and other relevant staff.

•Changes in the volume and severity of past due loans and leases, the volume of non-accrual loans and leases, and the volume and severity of adversely classified or graded loans and leases.

•Changes in the quality of the Bank's credit review system.

•Changes in the value of the underlying collateral for collateral-dependent loans and leases.

•The existence and effect of any concentrations of credit, and changes in the level of such concentrations.

•The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the Bank's existing portfolio.

The Company evaluated each qualitative factor as of September 30, 2020, and concluded that a $40.6 million increase to the model results was appropriate for the allowance for credit losses on loans and leases, due to model limitations in the current economic environment. The Company also determined that a $5.0 million increase to the calculated results was appropriate for the RUC related to construction loans. Models were deemed to be under predicting losses, because certain economic variables were lagging indicators and had not yet shown the effects of the current recession, and models were not appropriately capturing elevated risk associated with payment deferral programs offered by the Bank.

Loss factors from the models, prepayment speeds, and qualitative factors are input into the Company's CECL accounting application which aggregates the information. The Company then uses two methods to calculate the current expected credit loss: 1) the discounted cash flow ("DCF") method, which is used for all loans except lines of credit and 2) the non-discounted cash flow method which is used for lines of credit due to difficulty of calculating an effective interest rate when lines have yet to be drawn on. The DCF method utilizes the effective interest rate of individual assets to discount the expected credit losses adjusted for prepayments. The difference in the net present value and the amortized cost of the asset will result in the required allowance. The non-discounted cash flow method uses the exposure at default, along with the expected credit losses adjusted for prepayments to calculate the required allowance.

Asset Quality and Non-Performing Loans and Leases

The Bank manages asset quality and control credit risk through diversification of the loan and lease portfolio and the application of policies designed to promote sound underwriting and loan and lease monitoring practices. The Bank's Credit Quality Administration is charged with monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank. Reviews of non-performing, past due loans and leases and larger credits, designed to identify potential charges to the allowance for credit losses, and to determine the adequacy of the allowance, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers, the value of the applicable collateral, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions and other factors.

Loans and Leases Past Due and Non-Accrual Loans and Leases

Typically, loans in a non-accrual status will not have an allowance for credit loss as they will be written down to their net realizable value or charged-off. However, the net realizable value for homogeneous leases and equipment finance agreements is determined by the LGD calculated by the CECL model and therefore leases and equipment finance agreements on non-accrual will have an allowance for credit losses until they become 181 days past due, at which time they are charged-off. The Company recognized no interest income on non-accrual loans and leases during the three and nine months ended September 30, 2020. As of September 30, 2020, loans of approximately $782.3 million are currently deferred under the CARES Act or interagency guidance and are classified as current as their contractual payments have been deferred.

The following tables present the amortized cost basis of the loans and leases past due, by loan and lease class, as of September 30, 2020 and December 31, 2019:

Troubled Debt Restructurings

At September 30, 2020 and December 31, 2019, troubled debt restructured loans of $15.8 million and $18.6 million, respectively, were classified as accruing TDR loans. The TDRs were granted in response to borrower financial difficulties, and generally provide for a temporary modification of loan repayment terms. In order for a new TDR loan to be considered for accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow.

The following tables present TDR loans by accrual versus non-accrual status and by portfolio segment as of September 30, 2020 and December 31, 2019:

COVID-19 Related Payment Deferral and Forbearance

Due to the deterioration of the US economy resulting from the COVID-19 pandemic, the Company has had an increase in loan payment deferral and forbearance requests. Once a deferral or forbearance request is received, a late charge waiver is put in place and payments are suspended for an agreed-upon period. Accrued and unpaid interest during the deferral period will be collected upon the expiration of the deferral or on a regular repayment schedule at the end of the deferral period. For certain loan types, the maturity date may be extended one to six months to allow for full amortization. In accordance with the CARES Act and interagency guidance, these loans are generally classified based on their past due status prior to their deferral period, so they are classified as performing loans that accrue interest.

Credit Quality Indicators

Management regularly reviews loans and leases in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading. In addition, the board reviews and approves the credit quality indicators each year. The Bank differentiates its lending portfolios into homogeneous and non-homogeneous loans and leases. Homogeneous loans and leases are risk rated on a single risk rating scale based on the past due status of the loan or lease.

The Bank's risk rating methodology for its non-homogeneous loans and leases uses a dual risk rating approach to assess the credit risk. This approach uses two scales to provide a comprehensive assessment of credit default risk and recovery risk. The probability of default scale measures a borrower's credit default risk using risk ratings ranging from 1 to 16, where a higher rating represents higher risk. For non-homogeneous loans and leases, PD ratings of 1 through 9 are "pass" grades, while PD ratings of 10 and 11 are "watch" grades. PD ratings of 12-16 correspond to the regulatory-defined categories of special mention (12), substandard (13-14), doubtful (15), and loss (16). The loss given default scale measures the amount of loss that may not be recovered in the event of a default, using six alphabetic ratings from A-F, where a higher rating represents higher risk. The LGD scale quantifies recovery risk associated with an event of default and predicts the amount of loss that would be incurred on a loan or lease if a borrower were to experience a major default and includes variables that may be external to the borrower, such as industry, geographic location, and credit cycle stage. It could also include variables specific to the borrower such as their probability of default and bankruptcies as well as variables specific to the loan or lease, including collateral valuation, covenant structure and debt type. The product of the borrower's PD and a loan or lease LGD is the loan or lease expected loss, expressed as a percentage. This provides a common language of credit risk across different loans.

The PD scale estimates the likelihood that a borrower will experience a major default on any of its debt obligations within a specified time period. Examples of major defaults include payments 90 days or more past due, non-accrual classification, bankruptcy filing, or a full or partial charge-off of a loan or lease. As such, the PD scale represents the credit quality indicator for non-homogeneous loans and leases.

The credit quality indicator rating categories follow regulatory classification and can be generally described by the following groupings for loans and leases:

Pass—A pass loan or lease is a loan or lease with a credit risk level acceptable to the Bank for extending credit and maintaining normal credit monitoring.

Watch—A watch loan or lease is considered pass rated but has a heightened level of unacceptable default risk due to an emerging risk element or declining performance trend. Watch ratings are expected to be temporary, with issues resolved or manifested to the extent that a higher or lower risk rating would be appropriate within a short period of time.

Special Mention—A special mention loan or lease has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution's credit position at some future date. These borrowers have an elevated probability of default but not to the point of a substandard classification.

Substandard—A substandard asset is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

Doubtful—Loans or leases classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and values, highly questionable and improbable.

Loss—Loans or leases classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted.

The following table represents the amortized costs basis of the loans and leases by credit classification and vintage year by loan and lease class of financing receivable as of September 30, 2020:

Note 5 – Residential Mortgage Servicing Rights 

 

The Company measures its residential mortgage servicing rights ("MSR") at fair value with changes in fair value reported in residential mortgage banking revenue. The following table presents the changes in the Company's residential mortgage servicing rights for the three and nine months ended September 30, 2020 and 2019: 

			Three Months Ended												Nine Months Ended
(in thousands)			September 30, 2020						September 30, 2019						September 30, 2020						September 30, 2019
Balance, beginning of period			$	96,356					$	139,780					$	115,010					$	169,025
Additions for new MSR capitalized			14,014						7,393						37,484						16,772
Changes in fair value:
Changes due to collection/realization of expected cash flows over time			(4,878)						(6,835)						(15,249)						(20,171)
Changes due to valuation inputs or assumptions (1)			(12,244)						11,045						(43,997)						(14,243)
Balance, end of period			$	93,248					$	151,383					$	93,248					$	151,383

(1) The changes in valuation inputs and assumptions principally reflect changes in discount rates and prepayment speeds, which are primarily affected by changes in interest rates.

Information related to the Bank's serviced loan portfolio as of September 30, 2020 and December 31, 2019 is as follows: 

(dollars in thousands)			September 30, 2020						December 31, 2019

The amount of contractually specified servicing fees, late fees and ancillary fees earned, recorded in residential mortgage banking revenue on the Condensed Consolidated Statements of Income, was $8.8 million and $26.2 million for the three and nine months ended September 30, 2020, respectively, as compared to $11.3 million and $33.2 million for the three and nine months ended September 30, 2019, respectively.

Note 6 – Commitments and Contingencies 

 

Financial Instruments with Off-Balance-Sheet Risk — The Company's financial statements do not reflect various commitments and contingent liabilities that arise in the normal course of the Bank's business and involve elements of credit, liquidity, and interest rate risk. 

 

The following table presents a summary of the Bank's commitments and contingent liabilities:  

(in thousands)			September 30, 2020
Commitments to extend credit			$	5,785,909
Forward sales commitments			$	1,029,734
Commitments to originate residential mortgage loans held for sale			$	950,570
Standby letters of credit			$	101,978

 

The Bank is a party to financial instruments with off-balance-sheet credit risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Those instruments involve elements of credit and interest-rate risk similar to the risk involved in on-balance sheet items. The contract or notional amounts of those instruments reflect the extent of the Bank's involvement in particular classes of financial instruments. 

 

The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, and financial guarantees written, is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. 

There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three and nine months ended September 30, 2020 and 2019. At September 30, 2020, approximately $91.5 million of standby letters of credit expire within one year, and $10.5 million expire thereafter.

Residential mortgage loans sold into the secondary market are sold with limited recourse against the Company, meaning that the Company may be obligated to repurchase or otherwise reimburse the investor for incurred losses on any loans that suffer an early payment default, are not underwritten in accordance with investor guidelines or are determined to have pre-closing borrower misrepresentations. As of September 30, 2020, the Company had a residential mortgage loan repurchase reserve liability of $1.6 million. For loans sold to GNMA, the Bank has a unilateral right, but not the obligation, to repurchase loans that are past due 90 days or more. As of September 30, 2020, the Bank has recorded a liability for the loans subject to this repurchase right of $20.0 million, and has recorded these loans as part of the loan portfolio as if the Bank had repurchased these loans.

 

Commitments — In September 2020, the Company and its wholly-owned subsidiary Umpqua Investments, entered into an agreement to sell substantially all of the assets of Umpqua Investments to Steward Partners. Umpqua Investments is included within the Company's Wealth Management segment. The acquisition is expected to close in the first quarter of 2021, subject to customary closing conditions.

Legal Proceedings—Umpqua is involved in legal proceedings occurring in the ordinary course of business. Based on information currently available, advice of counsel and available insurance coverage, management believes that the eventual outcome of actions against the Company or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on its consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to results of operations for any particular period.

Concentrations of Credit Risk— The Bank grants real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers throughout Oregon, Washington, California, Idaho, and Nevada. In management's judgment, a concentration exists in real estate-related loans, which represented approximately 71% and 76% of the Bank's loan and lease portfolio at September 30, 2020 and December 31, 2019, respectively. The decrease is related to PPP loans which are not real estate secured and will likely be short-term in duration. Commercial real estate concentrations are managed to ensure geographic and business diversity, primarily in our footprint. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general or caused by the COVID-19 pandemic, material increases in interest rates, changes in tax policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary market areas in particular, could have an adverse impact on the repayment of these loans.  Personal and business incomes, proceeds from the sale of real property, or proceeds from refinancing represent the primary sources of repayment for a majority of these loans. 

 

The Bank recognizes the credit risks inherent in dealing with other depository institutions. Accordingly, to prevent excessive exposure to any single correspondent, the Bank has established general standards for selecting correspondent banks as well as internal limits for allowable exposure to any single correspondent. In addition, the Bank has an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

  

Note 7 – Derivatives 

 

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy. 

The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments.  Credit risk associated with forward contracts is limited to the replacement cost of those forward contracts in a gain position.  There were no counterparty default losses on forward contracts in the three and nine months ended September 30, 2020 and 2019.  Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward contracts with broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker/dealer equal to the increase or decrease in the market value of the forward contract. At September 30, 2020, the Bank had commitments to originate mortgage loans held for sale totaling $950.6 million and forward sales commitments of $1.0 billion, which are used to hedge both on-balance sheet and off-balance sheet exposures. 

 

The Bank executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of September 30, 2020, the Bank had 884 interest rate swaps with an aggregate notional amount of $6.2 billion related to this program.  As of December 31, 2019, the Bank had 846 interest rate swaps with an aggregate notional amount of $5.7 billion related to this program.

At both September 30, 2020 and December 31, 2019, the termination value of interest rate swaps in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $65,000 and $7.0 million, respectively. The Bank has collateral posting requirements for initial margins with its clearing members and clearing houses and has been required to post collateral against its obligations under these agreements of $103.1 million and $86.2 million as of September 30, 2020 and December 31, 2019, respectively. 

The Bank's interest rate swap derivatives are cleared through the Chicago Mercantile Exchange and London Clearing House. These clearing houses characterize the variation margin payments, for derivative contracts that are referred to as settled-to-market, as settlements of the derivative's mark-to-market exposure and not collateral. The Company accounts for the variation margin as an adjustment to cash collateral, as well as a corresponding adjustment to derivative asset and liability. As of September 30, 2020 and December 31, 2019, the variation margin adjustments were negative adjustments of $374.8 million and $144.8 million, respectively.

The Bank incorporates credit valuation adjustments ("CVA") to appropriately reflect nonperformance risk in the fair value measurement of its derivatives. The net CVA reduced the settlement values of the Bank's net derivative assets by $22.5 million and $9.1 million as of September 30, 2020 and December 31, 2019, respectively. Various factors impact changes in the CVA over time, including changes in the credit spreads of the parties to the contracts, as well as changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

The Bank also executes foreign currency hedges as a service for customers. These foreign currency hedges are then offset with hedges with other third-party banks to limit the Bank's risk exposure.

The Bank's derivative assets are included in other assets, while the derivative liabilities are included in other liabilities on the condensed consolidated balance sheet. The following table summarizes the types of derivatives, separately by assets and liabilities, and the fair values of such derivatives as of September 30, 2020 and December 31, 2019:

There were 763,000 and 1.2 million weighted average outstanding restricted shares that were not included in the computation of diluted earnings per common share because their effect would be anti-dilutive for the three and nine months ended September 30, 2020, respectively.

Note 9 – Segment Information 

 

The Company reports four primary segments: Wholesale Bank, Wealth Management, Retail Bank, and Home Lending with the remainder as Corporate and other.

The Wholesale Bank segment includes lending, treasury and cash management services and customer risk management products to middle market corporate, commercial and business banking customers and includes the operations of FinPac, a commercial leasing company. The Wealth Management segment consists of the operations of Umpqua Investments, which offers a full range of retail brokerage and investment advisory services and products to its clients who consist primarily of individual investors, and Umpqua Private Bank, which serves high net worth individuals with liquid investable assets and provides customized financial solutions and offerings. The Retail Bank segment includes retail and small business lending and deposit services for customers served through the Bank's store network. The Home Lending segment originates, sells and services residential mortgage loans. The Corporate and other segment includes activities that are not directly attributable to one of the four principal lines of business and includes the operations of the parent company, eliminations and the economic impact of certain assets, capital and support functions not specifically identifiable within the other lines of business.

Management monitors the Company's results using an internal performance measurement accounting system, which provides line of business results and key performance measures. The application and development of these management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised retrospectively. In the current period, certain business banking related departments were moved from Retail Bank to Wholesale Bank to realign with Umpqua's strategic goals. The prior periods have been revised accordingly.

The provision for income taxes is typically allocated to business segments using a 25% effective tax rate. The residual income tax expense or benefit arising from tax planning strategies or other tax attributes to arrive at the consolidated effective tax rate is retained in Corporate and Other.

Summarized financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables:

(1) The Wholesale Bank and Retail Bank do not have the standard tax rate of 25% allocated in 2020 due to the impact of the goodwill impairment on these reporting units.

(2) The Corporate & Other segment reflects the recording of the deferred fees and costs on loans originated during the period, as the loan fees and costs are reflected within net interest income and non-interest expense, respectively, upon loan origination for the Wholesale Bank, Retail Bank, Home Lending, and Wealth Management segments.

(1) Other investment securities includes securities held by Umpqua Investments as trading debt securities.

The following methods were used to estimate the fair value of each class of financial instrument that is carried at fair value in the tables above: 

 

Securities— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.

 

Loans Held for Sale— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights.

 

Residential Mortgage Servicing Rights— The fair value of the MSRs is estimated using a discounted cash flow model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants.

Table of Contents

Junior Subordinated Debentures— The fair value of junior subordinated debentures is estimated using an income approach valuation technique.  The significant inputs utilized in the estimation of fair value of these instruments are the credit risk adjusted spread and three-month LIBOR. The credit risk adjusted spread represents the nonperformance risk of the liability, contemplating the inherent risk of the obligation. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants.  Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, the Company has classified this as a Level 3 fair value measurement.  

 

Derivative Instruments— The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate.  The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2020, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.   

 

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3) 

 

The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at September 30, 2020: 

Financial Instrument						Fair Value						Valuation Technique						Unobservable Input						Range of Inputs						Weighted Average
Residential mortgage servicing rights						$	93,248					Discounted cash flow
																		Constant prepayment rate						9.68 - 79.94%						18.10%
																		Discount rate						9.50 - 12.50%						9.74%
Interest rate lock commitments						$	28,839					Internal pricing model
																		Pull-through rate						49.79 - 100.00%						84.78%
Junior subordinated debentures						$	247,045					Discounted cash flow
																		Credit spread						4.36 - 5.78%						4.94%

Generally, increases in the constant prepayment rate or the discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in a decrease in fair value. Conversely, decreases in the constant prepayment rate or the discount rate will result in an increase in fair value.

An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate will result in a decrease in the fair value measurement.

Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, which is an inactive market. Management attributes the change in fair value of the junior subordinated debentures during the period to market changes in the nonperformance expectations and pricing of this type of debt. The widening of the credit risk adjusted spread above the Company's contractual spreads has primarily contributed to the decrease in the estimated fair value.  Future contractions in the instrument-specific credit risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of September 30, 2020, or the passage of time, will result in an increase in the estimated fair value.  Generally, an increase in the credit spread will result in a decrease in the estimated fair value. Conversely, a decrease in the credit spread will result in an increase in the estimated fair value.

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments carried at fair value are recorded in residential mortgage banking revenue within non-interest income. The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities. 

The change in fair value of junior subordinated debentures is attributable to the change in the instrument specific credit risk; accordingly, the unrealized losses on fair value of junior subordinated debentures of $14.6 million and unrealized gains of $26.9 million, respectively, for the three and nine months ended September 30, 2020, are recorded net of tax as an other comprehensive loss of $10.8 million and other comprehensive income of $20.0 million, respectively. Comparatively, unrealized gains of $8.5 million and $32.3 million, respectively, were recorded net of tax as an other comprehensive income of $6.3 million and $24.0 million for the three and nine months ended September 30, 2019. The gain recorded for the nine months ended September 30, 2020 is due mostly to an overall increase in the discount rates due to an increase in the credit spread, in addition to the implied forward curve shifting lower. The loss recorded for the three months ended September 30, 2020 was due primarily to a decrease in the credit spread which resulted in a lower discount rate and an increase in the forward curve partially offset by an increase in the spot curve.

From time to time, certain assets are measured at fair value on a nonrecurring basis.  These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral dependent loans.

Goodwill was evaluated for impairment as of March 31, 2020, for the Retail Bank and Wholesale Bank reporting units. Refer to Note 11 - Goodwill, for discussion of the Company's goodwill impairment analysis.

The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis, excluding goodwill. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information for loans and leases and other real estate owned.

The loans and leases amounts above represent collateral dependent loans and leases that have been adjusted to fair value.  When a loan or non-homogeneous lease is identified as collateral dependent, the Bank measures the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan or lease, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little to no value.  When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is determined that the collateral has little to no value. If it is determined that the value of the collateral dependent loan or lease is less than its recorded investment, the Bank recognizes this impairment and adjusts the carrying value of the loan or lease to fair value, less costs to sell, through the allowance for credit losses. The loss represents charge-offs on collateral dependent loans and leases for fair value adjustments based on the fair value of collateral.

The other real estate owned amount above represents impaired real estate that has been adjusted to fair value.  Other real estate owned represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate. 

Fair Value Option

The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option as of September 30, 2020 and December 31, 2019:

			September 30, 2020																		December 31, 2019
(in thousands)			Fair Value						Aggregate Unpaid Principal Balance						Fair Value Less Aggregate Unpaid Principal Balance						Fair Value						Aggregate Unpaid Principal Balance						Fair Value Less Aggregate Unpaid Principal Balance
Loans held for sale			$	677,773					$	644,507					$	33,266					$	513,431					$	496,683					$	16,748

Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue. For the three and nine months ended September 30, 2020, the Company recorded a net increase in fair value of $2.2 million and $16.5 million, respectively. For the three and nine months ended September 30, 2019, the Company recorded a net decrease in fair value of $1.9 million and an increase of $5.8 million, respectively.

The Company selected the fair value measurement option for certain junior subordinated debentures. The remaining junior subordinated debentures were acquired through previous business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost.

Accounting for the selected junior subordinated debentures at fair value enables the Company to more closely align financial performance with the economic value of those liabilities. Additionally, it improves the ability to manage the market and interest rate risks associated with the junior subordinated debentures. The junior subordinated debentures measured at fair value and amortized cost are presented as separate line items on the balance sheet. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants under current market conditions as of the measurement date.

Due to inactivity in the junior subordinated debenture market and the lack of observable quotes of the Company's, or similar, junior subordinated debenture liabilities or the related trust preferred securities when traded as assets, the Company utilizes an income approach valuation technique to determine the fair value of these liabilities using estimation of market discount rate assumptions. The Company monitors activity in the trust preferred and related markets, to the extent available, evaluates changes related to the current and anticipated future interest rate environment, and considers entity-specific creditworthiness, to validate the reasonableness of the credit risk adjusted spread and effective yield utilized in the discounted cash flow model. The Company also considers changes in the interest rate environment in the valuation, specifically the absolute level and the shape of the slope of the forward swap curve.

Note 11 – Goodwill

At September 30, 2020, goodwill totaled $2.7 million, after a goodwill impairment of $1.8 billion was recorded as of March 31, 2020. Goodwill was $1.8 billion at December 31, 2019. Goodwill is required to be allocated to reporting units, which the Company has determined to be the same as its operating segments.

The following table summarizes the change in the Company's goodwill for the nine months ended September 30, 2020:

						Goodwill
(in thousands)						Gross						Accumulated Impairment						Total
Balance, December 31, 2019						$	1,900,727					$	(113,076)					$	1,787,651
Goodwill impairment						—						(1,784,936)						(1,784,936)
Balance, September 30, 2020						$	1,900,727					$	(1,898,012)					$	2,715

As of September 30, 2020 and December 31, 2019, goodwill was allocated to the reporting units as follows:

			Goodwill
(in thousands)			Wholesale Bank						Wealth Management						Retail Bank						Total
Allocated goodwill, December 31, 2019			$	1,033,744					$	2,715					$	751,192					$	1,787,651
Goodwill impairment			(1,033,744)						—						(751,192)						(1,784,936)
Allocated goodwill, September 30, 2020			$	—					$	2,715					$	—					$	2,715

The Company updated its goodwill assessment for the Wholesale Bank and Retail Bank reporting units as of March 31, 2020, due to events and circumstances indicating potential impairment. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit.

The Company assessed qualitative factors that indicated that it was more likely than not that goodwill was impaired as of March 31, 2020. Based on that assessment, the Company determined that for the Wholesale Bank and Retail Bank reporting units, the qualitative analysis determined that there were negative indicators that would require a quantitative assessment of goodwill due to the decline in the current economic environment, specifically interest rates and the Company's stock price, as well as decreasing cash flow projections for these reporting units based on the low interest rate environment and potentially higher credit losses.

The Company performed a quantitative analysis of the Wholesale Bank and Retail Bank reporting units, by comparing the fair value of these reporting units with their carrying amount. The Company estimated the fair value of its Wholesale Bank and Retail Bank reporting units using an income approach to estimate the fair value of both reporting units. The income approach estimates the fair value of the reporting units by discounting management's projections of the reporting units' cash flows, including a terminal value to estimate the fair value of cash flows beyond the final year of projected results, discounted using an estimated cost of capital discount rate. The Company also considered the market and cost approaches when determining the fair value of the reporting units.

The projected cash flows used to estimate fair value of the reporting units was lower than previous projections due to declining interest rate forecasts for a prolonged low-interest rate environment, due to the significant impact of the Federal Reserve's rate cuts and the impact of the COVID-19 pandemic on the economy. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates, and market factors. Estimating the fair value of individual reporting units requires management to make assumptions and estimates regarding the Company's future plans, as well as industry, economic, and regulatory conditions. These assumptions and estimates include estimated future annual net cash flows, income tax rates, discount rates, growth rates, and other market factors.

Upon completing the quantitative impairment analysis as of March 31, 2020, the Company recorded a goodwill impairment of $1.8 billion, which represented the entire amount of goodwill allocated to the Wholesale Bank and Retail Bank reporting units. The remaining goodwill of $2.7 million after the impairment relates to the Wealth Management reporting unit. As of September 30, 2020, the Company updated its goodwill impairment analysis for the Wealth Management reporting unit by assessing qualitative factors to determine whether the existence of events and circumstances indicated that it is more likely than not that goodwill is impaired. Based upon that assessment, the Company determined that there were no additional factors indicating impairment and no further testing was determined to be necessary as of September 30, 2020.

Note 12 - Income Taxes

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as in the majority of states and in Canada. As of September 30, 2020, the Company has a net deferred tax liability of $13.2 million, which includes $2.0 million of state net operating loss ("NOL") carry-forwards, expiring in tax years 2029-2031. The Company believes that it is more likely than not that the benefit from only certain state NOL carry-forwards will not be realized and therefore has provided a valuation allowance of $1.1 million against the deferred tax assets relating to these NOL carry-forwards. The Company had gross unrecognized tax benefits of $4.3 million as of September 30, 2020. If recognized, the unrecognized tax benefit would reduce the 2020 annual effective tax rate by 0.27%.

The Company's consolidated effective tax rate as a percentage of pre-tax income (loss) for the three and nine months ended September 30, 2020 was 21.3% and (4.4)%, respectively, as compared to 23.6% and 24.5% for the three and nine months ended September 30, 2019. The effective tax rate decreased from the prior year primarily due to the impairment of non-deductible goodwill during the nine months ended September 30, 2020. Additionally, the effective tax rates differed from the statutory rate principally because of state taxes, non-taxable income arising from bank owned life insurance, income on tax-exempt investment securities, non-deductible FDIC premiums and tax credits arising from low-income housing investments.

Executive Overview 

 

Recent Developments – COVID-19

We expect that the COVID-19 pandemic and the related governmental reaction will continue to negatively impact the economy and our business including our results of operations and stock price among other negative impacts. The government's reactions to the COVID-19 pandemic has also had a positive impact on our business, including our involvement in the PPP, as well as increased mortgage loan production fueled by the decline in interest rates, although these benefits may be short-term in nature. The risks to our business are more fully described in Part II, item 1A "Risk Factors" of this Quarterly Report on Form 10-Q. We are closely monitoring the impact of COVID-19 on all aspects of our business.

At this time, we are unable to predict the extent and magnitude of the negative impact on our business of the COVID-19 pandemic and related governmental reaction due to numerous uncertainties. To limit the impact of COVID-19 on our business operations, customers and associates, we have modified our operations to comply with multiple state-level proclamations and Centers for Disease Control and Prevention ("CDC") guidance and best practices by restricting travel, maintaining remote work programs for associates, restricting lobby access to stores and having customers bank by appointment, online, or via our app, increasing facilities cleaning scope and frequency, and deploying resources for new programs such as the Payroll Protection Program ("PPP"). We have also addressed other customer needs during the pandemic by continuing to offer our Umpqua Go-To® application which offers customers and associates a safe and effective way to conduct banking. As of September 30, 2020, we funded approximately 16,900 PPP loans, totaling $2.0 billion, to help businesses maintain their workforce and cover other working capital needs during the COVID-19 pandemic.

We have increased our community support by allocating $3.0 million in grants and investments to organizations providing COVID-19 community relief and small business microloans, activating an associate 3:1 giving match to donations, and initiating virtual volunteerism opportunities. We enhanced associate benefits by introducing supplemental front line associate pay, providing a pandemic pay bank for associates needing additional paid time off due to COVID-19 impacts, and implementing flexible work rotations and remote work for higher-risk associates.

While we do not know and cannot quantify all of the specific impacts, the extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic; actions taken by governmental authorities and other third parties in response to the pandemic; the effect on our customers, counterparties, employees and third party service providers; and the effect on the economy and markets.

Due to the COVID-19 pandemic, the Umpqua Go-To® application's message volumes have increased as the application provides customers and bankers with a socially-distant way to conduct transactions and get answers to critical questions. During this difficult time, we continue to focus on operational excellence and on the well-being of our customers, associates, and communities.

Social Justice Initiatives

As part of our community support, Umpqua prioritized strategic investments and resource allocation to support minority-owned businesses, which are most vulnerable during the pandemic. This support includes $750,000 in community development and Equity Equivalent ("EQ2") investments to provide support for women and minority owned businesses. Umpqua bankers are providing expertise through virtual volunteering programs and small business banker's hours. We are also providing free use of space at local stores in numerous localities to support their small businesses.

Wildfire Support

Due to the recent wildfires impacting the West Coast, Umpqua has committed $750,000 in relief across our footprint, including $100,000 in grants for response and recovery; $350,000 in EQ2 to support impacted small businesses in Oregon and $300,000 in EQ2 to support small businesses in California and Washington. We also activated our 3:1 match program to include wildfire relief and increased the eligible associate match. In addition, we support active associate volunteering to organize supply drives, sharing critical information, as well as donating money, time, talent, space, and resources as Umpqua associates are active in the many communities impacted by the wildfires.

The following is a discussion of our results for the three and nine months ended September 30, 2020 as compared to the applicable prior periods.

Financial Performance

 

•Net income per diluted common share was $0.57 and net loss per diluted common share was $7.60 for the three and nine months ended September 30, 2020, respectively, as compared to net income per diluted common share of $0.38 and $1.23 for the three and nine months ended September 30, 2019.  The increase in net income for the three months ended September 30, 2020, is due primarily to an increase in residential mortgage banking income. The net loss for the nine months ended September 30, 2020, is due to the goodwill impairment, increased provision for credit losses, as well as interest margin compression.

•As of March 31, 2020, the Company recorded a goodwill impairment of $1.8 billion. An interim impairment analysis was completed due to the decline in the economic environment, specifically the impact of significant decreases in interest rates, declines in the Company's stock price, as well as potentially higher credit losses. The non-cash goodwill impairment recorded does not impact tangible equity or our regulatory capital ratios. There was no further goodwill impairment indicated as of September 30, 2020.

 

•Net interest margin, on a tax equivalent basis, was 3.08% and 3.19% for the three and nine months ended September 30, 2020, respectively, as compared to 3.63% and 3.78% for the three and nine months ended September 30, 2019.  The decrease in net interest margin for the three and nine months ended September 30, 2020, compared to the same periods in the prior year, was driven by lower yields on interest-earning assets offset by higher volume, due to the interest rate cuts that the Federal Reserve instituted as a response to the COVID-19 pandemic. The decrease was partially offset by a reduction in the cost of interest-bearing liabilities from the Company's management of the cost of our funding sources.

•Residential mortgage banking revenue was $90.4 million and $191.8 million for the three and nine months ended September 30, 2020, respectively, as compared to $47.0 million and $67.8 million for the three and nine months ended September 30, 2019.  The increase in residential mortgage banking revenue for the three and nine months ended September 30, 2020 was primarily driven by an increase in originations in the current year due to elevated refinance demand due to lower interest rates. This resulted in increases in the income from the origination and sale of residential mortgages of $67.3 million and $155.9 million, for the three and nine months ended September 30, 2020, respectively, as compared to the same periods in the prior year. This was offset by higher origination expense and by losses on the fair value of the MSR asset due to increases in the prepayment speeds.

•For-sale mortgage closed loan volume increased by 128% and 141% for the three and nine months ended September 30, 2020, respectively, as compared to the same periods in the prior year. In addition, the gain on sale margin increased to 5.13% and 4.59%, for the three and nine months ended September 30, 2020, respectively, as compared to 3.72% and 3.40% in the same periods of the prior year. The increase in the gain on sale margin is due to constrained industry capacity.

•Total gross loans and leases were $22.4 billion as of September 30, 2020, an increase of $1.2 billion, as compared to December 31, 2019.  The increase in total loans is primarily due to the production of approximately 16,900 PPP loans totaling $2.0 billion, net of deferred fees and costs. Excluding PPP loan production, loan balances declined due to reduced origination activity in the current economic environment.

 

•Total deposits were $24.7 billion as of September 30, 2020, an increase of $2.2 billion, compared to December 31, 2019.  This increase was due to growth in non-interest bearing demand deposits, which is attributable to an increase in commercial customers' non-interest bearing accounts to increase their liquidity position, and personal customers decreasing discretionary spending. This increase is partially offset by decreases in time deposits.

 

•Total consolidated assets were $29.4 billion as of September 30, 2020, compared to $28.8 billion at December 31, 2019. The increase was mainly due to the increase in loans due to PPP loan production and an increase in on-balance sheet liquidity, offset by the goodwill impairment recorded in the first quarter of 2020 and an increase in the allowance for credit losses.

•The Company participates in the PPP, offering loans to both customers and non-customers throughout our footprint. As of September 30, 2020, the Company had processed approximately 16,900 PPP loans and funded $2.0 billion in PPP loans, with an average customer loan balance of $122,000. The PPP loans will increase loan balances temporarily as PPP specific loan balances will decline as customers complete the applicable loan forgiveness process through the Company and the SBA.

Credit Quality

•Non-performing assets increased to $79.1 million, or 0.27% of total assets, as of September 30, 2020, as compared to $67.5 million, or 0.23% of total assets, as of December 31, 2019. Non-performing loans and leases were $76.7 million, or 0.34% of total loans and leases, as of September 30, 2020, as compared to $64.2 million, or 0.30% of total loans and leases, as of December 31, 2019.

•The allowance for credit losses on loans and leases was $345.0 million, as of September 30, 2020, an increase of $187.4 million, as compared to December 31, 2019. The reserve for unfunded commitments was $24.3 million, as of September 30, 2020, an increase of $19.2 million, as compared to December 31, 2019. The significant increases in the allowances for credit losses are due to the economic forecasts anticipating a continued economic downturn as a result of the COVID-19 pandemic, as well as the implementation of CECL. The initial adjustment to the allowance for credit losses, which includes the allowance for credit losses on loans and leases and the reserve for unfunded commitments, with the adoption of CECL as of January 1, 2020, was $53.2 million.

•The recapture of credit losses was $338,000 for the three months ended September 30, 2020. The provision for credit losses was $204.8 million for the nine months ended September 30, 2020. This was compared to a provision for credit losses (including the provision related to the RUC) of $23.5 million and $56.8 million, respectively, for the three and nine months ended September 30, 2019. The decrease for the three months ended September 30, 2020, compared to the same period in 2019, was attributed to a stabilization of credit quality metrics and economic forecasts used in credit models as of September 30, 2020, along with a decline in loan balances for the three month period. The increase for the nine months ended September 30, 2020, compared to the same period of the prior year, was attributable to the economic forecasts influenced by the COVID-19 pandemic used in the CECL calculation of the allowance for credit losses. As an annualized percentage of average outstanding loans and leases, the provision for credit losses recorded for the three months ended September 30, 2020 was zero due to the small recapture, and for the nine months ended was 1.24%, as compared to 0.44% and 0.37% for the same periods in 2019.

Liquidity

•Total cash and cash equivalents was $2.2 billion as of September 30, 2020, an increase of $857.0 million from December 31, 2019. The increase in cash and cash equivalents reflects the Bank's current liquidity strategy to have an elevated on-balance sheet liquidity position to further enhance flexibility due to the increased market volatility and uncertainty as a result of the COVID-19 pandemic.

Capital and Growth Initiatives

•Umpqua launched "Next Gen 2.0" a continuation of our initiative to modernize the Bank. Like its predecessor, the Next Gen 2.0 program includes initiatives to grow revenue, invest in strategic areas for future growth, including technology and digital enhancements, and to continue to advance operational excellence goals to reduce operating costs and invest in strategic growth opportunities. We’re building on the strong foundation established over the past few years to continue streamlining the company’s operations in order to accelerate the development of a highly differentiated, human digital customer experience.

•The Company's total risk based capital ratio was 15.0% and its Tier 1 common to risk weighted assets ratio was 11.7% as of September 30, 2020. As of December 31, 2019, the Company's total risk based capital ratio was 14.0% and its Tier 1 common to risk weighted assets ratio was 11.2%.

 

•The Company paid a quarterly cash dividend of $0.21 per common share on August 31, 2020 to shareholders of record as of August 20, 2020. The Company has shifted the timing of any dividend declarations from historical intra-quarter announcements to after quarterly earnings are finalized and applicable regulatory approval processes are complete.

Summary of Critical Accounting Policies 

 

Our critical accounting policies are described in detail in the Summary of Critical Accounting Policies section of the Form 10-K for the year ended December 31, 2019, filed with the SEC on February 27, 2020. The SEC defines "critical accounting policies" as those that require application of management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in future periods. As of January 1, 2020, the Company implemented CECL, and due to the significance of the implementation, the following Allowance for Credit Losses Policy has been updated from the policies disclosed in our prior year financial statements. The Company's critical accounting policies also include residential mortgage servicing rights, valuation of goodwill, and fair value. There have been no other material changes to the valuation techniques or models during the nine months ended September 30, 2020. 

Allowance for Credit Losses Policy

The Bank has established an ACL Committee, which is responsible for, among other things, regularly reviewing the ACL methodology, including allowance levels and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The Company's Audit and Compliance Committee provides board oversight of the ACL process and reviews and approves the ACL methodology on a quarterly basis.

CECL is not prescriptive in the methodology used to determine the expected credit loss estimate. Therefore, management has flexibility in selecting the methodology. However, the expected credit losses must be estimated over a financial asset's contractual term, adjusted for prepayments, utilizing quantitative and qualitative factors.

The estimate of current expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms, and differences in economic conditions – both current conditions and reasonable and supportable forecasts. When the Company is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it has estimated expected credit losses for the remaining life after the forecasted period, using an approach that reverts to historical credit loss information.

The Company utilizes complex models to obtain reasonable and supportable forecasts; most of the models calculate two predictive metrics: the probability of default and loss given default. The PD measures the probability that a loan will default within a given time horizon and primarily measures the adequacy of the debtor's cash flow as the primary source of repayment of the loan or lease. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral.

Loans and leases deemed to be collateral dependent or reasonably expected troubled debt restructured or troubled debt restructured are individually evaluated for loss based on the value of the underlying collateral or a discounted cash flow analysis.

The Company considers various qualitative factors when determining the overall adequacy of the ACL, including changes within the portfolio, changes to Bank policies and processes, as well as external factors, which may result in qualitative overlays to the model results. Loss factors from the models, prepayment speeds, and qualitative factors are input into the Company's CECL accounting application which aggregates the information. The Company then uses two methods to calculate the current expected credit loss: 1) the discounted cash flow method, which is used for all loans except lines of credit and 2) the non-discounted cash flow method which is used for lines of credit due to the difficulty of calculating an effective interest rate when lines of credit have not yet been drawn on.

The reserve for unfunded commitments is established to absorb inherent losses associated with our commitment to lend funds, such as with a letter or line of credit. The adequacy of the ACL and RUC are monitored on a regular basis and are based on management's evaluation of numerous factors, including: the CECL model outputs; quality of the current loan portfolio; the trend in the loan portfolio's risk ratings; current economic conditions; loan concentrations; loan growth rates; past-due and non-performing trends; evaluation of specific loss estimates for all significant problem loans; historical charge-off and recovery experience; and other pertinent information.

Management believes that the ACL was adequate as of September 30, 2020. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could result in additional provision for loan and lease losses in future periods.

Results of Operations

 

Overview 

 

For the three months ended September 30, 2020, net income was $124.9 million or $0.57 per diluted common share, and for the nine months ended September 30, 2020, the net loss was $1.7 billion or $7.60 loss per diluted common share, which compares to net income of $84.5 million or $0.38 per diluted common share and $270.3 million or $1.23 per diluted common share for the three and nine months ended September 30, 2019, respectively.

The increase in net income for the three months ended September 30, 2020, compared to the same period of the prior year is attributable to an increase in non-interest income due mainly to increased residential mortgage banking revenue from strong mortgage production in the quarter, a decrease in interest expense, as well as a decrease in provision for credit losses, offset partially by a decrease in interest income and an increase in non-interest expenses during the period.

The decrease in interest expense was driven by a decrease in the expense on time deposits due to lower brokered deposits as the Company has allowed these higher-cost deposits to runoff, as well as the Company reducing promotional and exception pricing on customer money market and time deposits. The decrease in the provison for credit losses for the three months ended September 30, 2020, compared to the same period in 2019, was attributed to a stabilization of credit quality metrics and economic forecasts used in credit models as of September 30, 2020, along with a decline in loan balances for the three month period. The decrease in interest income is driven by lower average yields on interest-earning assets as market or index rates continued to decline. The increase in non-interest expense is due mainly to an increase in home lending compensation related to higher origination volumes during the quarter.

The decrease in net income for the nine months ended September 30, 2020, compared to the same period of the prior year is primarily attributable to the goodwill impairment of $1.8 billion and an increase in provision for credit losses. The goodwill impairment was due to an interim impairment analysis completed as of March 31, 2020, triggered by the deterioration in the economic environment, resulting from the COVID-19 pandemic, specifically the reduction in interest rates, the increase in projected credit losses, and the decline in the Company's stock price. The increase in the provision for credit losses is due to the COVID-19 pandemic influenced economic forecast used in the calculation of the allowance for credit losses using CECL. For the nine months ended September 30, 2019, the Bank also had a one-time gain on the sale of all of the Bank's Visa Inc. Class B common stock. The remaining changes are consistent with the discussion of the three months ended September 30, 2020 above.

The following table presents the return on average assets, average common shareholders' equity and average tangible common shareholders' equity for the three and nine months ended September 30, 2020 and 2019. For each period presented, the table includes the calculated ratios based on reported net income. Our return on average common shareholders' equity was negatively impacted as the result of capital required to support goodwill. To the extent this performance metric is used to compare our performance with other financial institutions that do not have merger and acquisition-related intangible assets, we believe it is beneficial to also consider the return on average tangible common shareholders' equity. The return on average tangible common shareholders' equity is calculated by dividing net income by average shareholders' common equity less average goodwill and intangible assets, net (excluding MSRs). The return on average tangible common shareholders' equity is considered a non-GAAP financial measure and should be viewed in conjunction with the return on average common shareholders' equity.

Additionally, management believes tangible common equity and the tangible common equity ratio are meaningful measures of capital adequacy. Umpqua believes the exclusion of certain intangible assets in the computation of tangible common equity and tangible common equity ratio provides a meaningful base for period-to-period and company-to-company comparisons, which management believes will assist investors in analyzing the operating results and capital of the Company.  Tangible common equity is calculated as total shareholders' equity less preferred stock and less goodwill and other intangible assets, net (excluding MSRs).  In addition, tangible assets are total assets less goodwill and other intangible assets, net (excluding MSRs).  The tangible common equity ratio is calculated as tangible common shareholders' equity divided by tangible assets. The tangible common equity and tangible common equity ratio is considered a non-GAAP financial measure and should be viewed in conjunction with the total shareholders' equity and the total shareholders' equity ratio. 

The following table provides a reconciliation of ending shareholders' equity (GAAP) to ending tangible common equity (non-GAAP), and ending assets (GAAP) to ending tangible assets (non-GAAP) as of September 30, 2020 and December 31, 2019: 

(dollars in thousands)			September 30, 2020						December 31, 2019
Total shareholders' equity			$	2,610,244					$	4,313,915
Subtract:
Goodwill			2,715						1,787,651
Other intangible assets, net			14,606						18,346
Tangible common shareholders' equity			$	2,592,923					$	2,507,918
Total assets			$	29,437,441					$	28,846,809
Subtract:
Goodwill			2,715						1,787,651
Other intangible assets, net			14,606						18,346
Tangible assets			$	29,420,120					$	27,040,812
Tangible common equity ratio			8.81		%				9.27		%

 

Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not reviewed or audited.  Although we believe these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools, and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP.

Net Interest Income 

 

Net interest income for the three and nine months ended September 30, 2020 was $216.6 million and $647.6 million, respectively, a decrease of $12.4 million and $46.2 million, respectively, compared to the same periods in 2019. The decrease in net interest income for the three and nine months ended September 30, 2020 as compared to the same periods in 2019, was driven by lower yields on interest-earning assets offset by higher volume, due to the interest rate cuts that the Federal Reserve instituted as a response to the COVID-19 pandemic, in addition to rate decreases in the second half of 2019. The decrease was partially offset by a lower cost of interest-bearing liabilities due to lower retail and brokered time deposits as the Bank has allowed these higher-cost deposits to runoff. In addition, the Bank is actively reducing deposit exception pricing to reduce the cost of deposits.

The net interest margin (net interest income as a percentage of average interest-earning assets) on a fully tax equivalent basis was 3.08% and 3.19% for the three and nine months ended September 30, 2020, respectively, as compared to 3.63% and 3.78% for the same periods in 2019. The decrease in net interest margin for the three and nine months ended September 30, 2020, primarily resulted from a decrease in the average yields on interest-earning assets, partially offset by the decline in the cost of interest-bearing liabilities and the increase in average loan and lease balances. In March 2020, in response to the COVID-19 pandemic, the Federal Open Market Committee ("FOMC") of the Federal Reserve System, lowered the target range for the federal funds rate 150 basis points to a range of 0.00% to 0.25%. The FOMC expects to maintain this target until it is confident that the economy has weathered recent events and is on track to achieve its maximum employment and price stability goals. Key interest rate declines experienced year to date have negatively impacted the Company's net interest margin.

The yield on loans and leases decreased by 97 and 81 basis points, respectively, for the three and nine months ended September 30, 2020, as compared to the same period in 2019, primarily attributable to the decrease in short and long-term interest rates, as well as the origination of PPP loans which have a low coupon rate. The cost of interest-bearing liabilities decreased 74 and 42 basis points, respectively, for the three and nine months ended September 30, 2020, as compared to the same period in 2019, also due to the decrease in interest rates and the runoff of brokered deposits.

 

Our net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, as well as changes in the yields earned on interest-earning assets and rates paid on deposits and borrowed funds. The Company continues to be "asset-sensitive." As interest rates have declined, the decrease in yields on earning assets has compressed the net interest margin, even as liabilities reprice downward. Further rate changes will continue to have an impact on our net interest margin. In addition, the increase in average loans and leases in the current period is due to PPP loans, which are expected to be short-term in nature due to SBA forgiveness of these loans, which could cause future net interest margin to decline as loan and lease balances decline.

Provision for Credit Losses 

 

The recapture of credit losses was $338,000 for the three months ended September 30, 2020. The provision for credit losses was $204.8 million for the nine months ended September 30, 2020. This was compared to a provision of $23.5 million and $56.8 million, respectively, for the three and nine months ended September 30, 2019 (which includes both the provision for loan and lease losses and the provision for the reserve for unfunded commitments). The change in the provision for three months ended September 30, 2020 as compared to the same prior year period, is primarily attributed to changes in the loan portfolio mix and balances as well as a stabilization of credit quality matrices and economic forecasts used in credit models in the current quarter. The change in the provision for the nine months ended September 30, 2020 as compared to the same prior year period is primarily attributable to CECL as well as the economic forecasts related to the COVID-19 pandemic. As an annualized percentage of average outstanding loans and leases, the provision for credit losses recorded for the three months ended September 30, 2020 was zero due to the small amount of recapture for the quarter, and 1.24% for the nine months ended September 30, 2020, as compared to 0.44% and 0.37% for the same periods in 2019. 

 

For the three and nine months ended September 30, 2020, net charge-offs were $13.5 million and $51.4 million, respectively, as compared to $18.0 million and $44.8 million, respectively, for the three and nine months ended September 30, 2019. As an annualized percentage of average outstanding loans and leases, net charge-offs for the three and nine months ended September 30, 2020 were 0.24% and 0.31%, respectively, as compared to 0.34% and 0.29% for the same periods in 2019. The increase in net charge-offs for the nine months ended September 30, 2020, was primarily due to a single charge-off on a syndicated national credit to a regional air transportation lessor whose financial conditions and prospects were adversely impacted by COVID-19 in the first quarter of 2020 as well as charge-offs related to the lease and equipment finance portfolio, which is included in the commercial loan portfolio.

Typically, loans in a non-accrual status will not have an allowance for credit loss as they will be written down to their net realizable value or charged-off. However, the net realizable value for homogeneous leases and equipment finance agreements are determined by the loss given default calculated by the CECL model, and therefore homogeneous leases and equipment finance agreements on non-accrual will have an allowance for credit loss amount until they become 181 days past due, at which time they are charged-off. The non-accrual leases and equipment finance agreements of $3.8 million as of September 30, 2020 have a related allowance for credit losses of $3.2 million, with the remaining loans written-down to their estimated fair value, less estimated costs to sell, and are expected to be resolved with no additional material loss, absent further decline in market prices. 

Non-Interest Income 

 

Non-interest income for the three and nine months ended September 30, 2020 was $131.9 million and $288.0 million, respectively, an increase of $43.4 million and $32.0 million or 49% and 12%, respectively, as compared to the same periods in 2019. The following table presents the key components of non-interest income for the three and nine months ended September 30, 2020 and 2019:  

			Three Months Ended																								Nine Months Ended

Service charges on deposits decreased by $2.2 million and $6.0 million for the three and nine months ended September 30, 2020 compared to the same periods in the prior year. The decrease is primarily related to the Bank waiving certain ATM fees and deposit account related fees as a result of the COVID-19 pandemic. In addition, there has been a change in customers' spending habits as a result of the COVID-19 pandemic, which has resulted in overdraft and interchange fees decreasing as customers are keeping more funds liquid and making fewer transactions.

Residential mortgage banking revenue for the three and nine months ended September 30, 2020, as compared to the same periods of 2019, increased by $43.4 million and $124.0 million, respectively. The increase for the three and nine month periods was primarily driven by an increase in originations in 2020 due to elevated refinance demand because of lower interest rates, which resulted in an increase in revenue related to originations and sale of residential mortgages of $67.3 million and $155.9 million, respectively, as compared to prior periods. This was offset by higher origination expenses and a higher loss on fair value of the MSR of $17.1 million and $59.2 million for the three and nine months ended September 30, 2020, respectively, compared to a gain of $4.2 million for the three months ended September 30, 2019 and a loss of $34.4 million for the nine months ended September 30, 2019. For-sale mortgage closed loan volume increased 128% or $1.1 billion and 141% or $2.9 billion, respectively, for the three and nine months ended September 30, 2020, as compared to prior periods. In addition, the gain on sale margin increased to 5.13% and 4.59%, respectively, for the three and nine months ended September 30, 2020, as compared to 3.72% and 3.40% in the same periods of the prior year due to constrained industry capacity.

Origination volume is generally linked to the level of interest rates. If rates fall, origination volume would be expected to be elevated relative to historical levels. If rates rise, origination volume would be expected to fall. Margins observed in the current quarter could be expected to narrow somewhat in future periods as mortgage industry capacity constraints ease and refinance demand is met. In addition, government-sponsored entity investors are increasing fees for refinance loans sold to them starting in December 2020, which may reduce refinance activity and gain on sale margins. The MSR asset value is also sensitive to interest rates, and generally falls with lower rates and rises with higher rates.

Servicing income was $8.8 million and $26.2 million, respectively, for the three and nine months ended September 30, 2020, as compared to $11.4 million and $33.2 million, for the same periods of 2019. Income was lower primarily due to a smaller portfolio of loans serviced for others, resulting from a sale of part of the servicing portfolio in 2019. Operating expenses associated with mortgage servicing activities are at risk of increasing in future periods due to the potential of higher default frequency as a result of the COVID-19 pandemic.

The following table presents our residential mortgage banking revenues for the three and nine months ended September 30, 2020 and 2019:

			Three Months Ended												Nine Months Ended
(in thousands)			September 30, 2020						September 30, 2019						September 30, 2020						September 30, 2019
Origination and sale			$	98,703					$	31,432					$	224,831					$	68,956
Servicing			8,796						11,358						26,209						33,218
Change in fair value of MSR asset:
Changes due to collection/realization of expected cash flows over time			(4,878)						(6,835)						(15,249)						(20,171)
Changes in valuation inputs or assumptions (1)			(12,244)						11,045						(43,997)						(14,243)
Balance, end of period			$	90,377					$	47,000					$	191,794					$	67,760

(1)The changes in valuation inputs and assumptions principally reflect changes in discount rates and prepayment speeds, which are primarily affected by changes in interest rates.

The loss on sale of debt securities of $7.2 million for the nine months ended September 30, 2019 was due to a strategic restructuring of our available for sale debt securities portfolio to reduce interest rate sensitivity, which has not been repeated in the current periods.

Gain on equity securities for the nine months ended September 30, 2019 was due to the one-time gain on sale of all of the shares of Visa Inc. Class B common stock held by the Company.

Other income for the three months ended September 30, 2020 increased by $3.6 million, when compared to the same period in the prior year, primarily due to the gain of $5.9 million on the sale of three stores during the three months ended September 30, 2020. Other income decreased by $8.0 million for the nine months ended September 30, 2020 when compared to the same period in the prior year, primarily due to the decline in revenue from market swap fees of $4.3 million and a loss on the swap derivative fair value of $2.3 million.

Non-Interest Expense 

 

Non-interest expense for the three and nine months ended September 30, 2020 was $190.2 million and $2.3 billion, respectively, an increase of $6.6 million and $1.8 billion or 4% and 336%, as compared to the same periods in 2019. Excluding the goodwill impairment, non-interest expense, for the nine months ended September 30, 2020, increased $14.2 million over the same period in the prior year. The following table presents the key elements of non-interest expense for the three and nine months ended September 30, 2020 and 2019:

nm = Not meaningful

Goodwill impairment of $1.8 billion was recorded as of March 31, 2020, due to an interim impairment analysis triggered by the decline in interest rates and economic impacts of COVID-19, as well as declines in the Company's stock price. The impairment was a result of market volatility and forecasts for a prolonged low interest rate environment, as well as estimated higher credit losses expected due to the economic downturn.

Salaries and employee benefits increased by $13.5 million and $35.3 million, respectively, for the three and nine months ended September 30, 2020 as compared to the same periods in the prior year. This increase is primarily related to an increase in home lending compensation of $10.6 million and $31.4 million for the three and nine months ended September 30, 2020, respectively, related to higher origination volumes during the period.

Communications expense decreased by $674,000 and $2.7 million for the three and nine months ended September 30, 2020, respectively, due to a decrease in data processing costs.

Marketing expense decreased by $1.9 million and $4.7 million, respectively, for the three and nine months ended September 30, 2020, as compared to the same periods in the prior year due to the advertising in 2019 to attract wholesale and middle-market customers and to promote our Umpqua Go-To® app.

Services expense decreased by $2.1 million and $6.4 million, respectively, for the three and nine months ended September 30, 2020, as compared to the same periods in the prior year. The decrease primarily relates to lower consulting fees related to engagements in the same period of the prior year to assist with the identification and implementation of operational efficiencies that did not recur in 2020. In addition, current consulting engagements have been put on hold in some cases due to COVID-19 related to economic uncertainties and cost containment measures.

Other non-interest expense decreased by $3.7 million and $10.0 million, respectively, for the three and nine months ended September 30, 2020, as compared to the same periods in the prior year. The decrease for the three and nine months ended September 30, 2020 is primarily related to a decrease in the loss on OREO, a decrease in exit and disposal costs, as well as a decrease in travel expenses as the Bank continues to limit travel and use remote collaboration tools.

Income Taxes 

 

The Company's consolidated effective tax rate as a percentage of pre-tax income (loss) for the three and nine months ended September 30, 2020, was 21.3% and (4.4)% as compared to 23.6% and 24.5% for the three and nine months ended September 30, 2019. The effective tax rate for the nine months ended September 30, 2020, declined primarily due to the impairment of non-deductible goodwill. Additionally, the effective tax rates differed from the statutory rate principally because of state taxes, non-taxable income arising from bank owned life insurance, income on tax-exempt investment securities, non-deductible FDIC premiums and tax credits arising from low income housing investments.

FINANCIAL CONDITION 

 

Cash and Cash Equivalents

Cash and cash equivalents were $2.2 billion at September 30, 2020, compared to $1.4 billion at December 31, 2019. The increase of interest bearing cash and temporary investments reflects management's strategy to adopt an elevated on-balance sheet liquidity position. Having high quality liquid assets enhances the Company's liquidity flexibility given the market volatility and uncertainty in the current environment.

Investment Securities 

 

Equity and other securities were $82.8 million at September 30, 2020, up from $80.2 million at December 31, 2019.

 

Investment debt securities available for sale were $2.9 billion as of September 30, 2020, compared to $2.8 billion at December 31, 2019.  The increase was due to purchases of $595.4 million of investment securities as well as an increase of $115.1 million in fair value of investment securities available for sale, offset by sales and paydowns of $604.6 million.

 

The following tables present the available for sale and held to maturity investment debt securities portfolio by major type as of September 30, 2020 and December 31, 2019: 

			Investment Securities Available for Sale
			September 30, 2020												December 31, 2019

Residential mortgage-backed securities and collateralized mortgage obligations			1,876,260						65		%				1,909,984						68		%
Total available for sale securities			$	2,898,700					100		%				$	2,814,682					100		%

Residential mortgage-backed securities and collateralized mortgage obligations			$	3,088					100		%				$	3,260					100		%
Total held to maturity securities			$	3,088					100		%				$	3,260					100		%

 

 

We review investment securities on an ongoing basis for the presence of impairment, taking into consideration current market conditions, fair value in relationship to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether we intend to sell a security or if it is likely that we will be required to sell the security before recovery of our amortized cost basis of the investment, which may be maturity, and other factors.   

 

Gross unrealized losses in the available for sale investment portfolio were $548,000 at September 30, 2020.  This consisted primarily of unrealized losses on residential mortgage-backed securities and collateralized mortgage obligations of $430,000. The unrealized losses were attributable to changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not attributable to changes in credit quality. In the opinion of management, no allowance for credit losses was considered necessary on these securities as of September 30, 2020.

Restricted Equity Securities 

 

Restricted equity securities were $50.1 million at September 30, 2020 and $46.5 million at December 31, 2019, the majority of which represents the Bank's investment in the FHLB of Des Moines. The increase is attributable to purchases of FHLB stock during the period due to additional borrowing activity driven by the Company's liquidity strategy to increase on balance-sheet liquidity in the current environment. FHLB stock is carried at par and does not have a readily determinable fair value. Ownership of FHLB stock is restricted to the FHLB and member institutions and can only be purchased and redeemed at par.

Loans and Leases

 

Total loans and leases outstanding at September 30, 2020 were $22.4 billion, an increase of $1.2 billion as compared to December 31, 2019. The increase is attributable to net new loan and lease originations of $1.3 billion, primarily due to our participation in the PPP. The increase was partially offset by loans sold of $57.4 million and net charge-offs of $51.4 million.

The following table presents the concentration distribution of the loan and lease portfolio, net of deferred fees and costs, as of September 30, 2020 and December 31, 2019:

In April 2020, the Bank began originating loans to qualified small businesses under the PPP administered by the SBA under the provisions of the CARES Act. Loans covered by the PPP may be eligible for loan forgiveness for certain costs incurred related to payroll, group health care benefit costs and qualifying mortgage, rent and utility payments. The remaining loan balance after forgiveness of any amounts is still fully guaranteed by the SBA and therefore these loans carry no allowance for credit loss as of September 30, 2020.

Terms of the PPP loans typically include the following:

•Fixed interest rate of 1.00%;

•Loans issued have a maturity date of two or five years, depending on their date of issuance, and have the ability to prepay with no fees;

•First payment deferred for up to six months, with the potential ability to extend for another six months;

•Loan forgiveness up to the full principal amount of the loan and any accrued interest, subject to certain requirements including that no more than 25% of the loan forgiveness amount may be attributable to non-payroll costs;

•No collateral or personal guarantees are required;

•Maximum amount limited to the lesser of $10.0 million or an amount calculated using a payroll-based formula.

In return for processing and booking the loan, the SBA will pay the lender a processing fee tiered by the size of the loan; 5% for loans of up to $350,000; 3% for loans greater than $350,000 and less than $2.0 million; and 1% for loans of at least $2.0 million.

Through September 30, 2020, we have funded approximately $2.0 billion of SBA-approved PPP loans to approximately 16,900 customers for an average customer loan balance of $122,000, which are classified as commercial term loans.We expect to recognize the remaining unamortized balance of the PPP-related net loan processing fees of approximately $51.2 million, as a yield adjustment over the remaining term of these loans.

(1)Excludes government guaranteed GNMA mortgage loans that Umpqua has the right but not the obligation to repurchase totaling $20.0 million and $4.3 million as of September 30, 2020 and December 31, 2019, respectively.

(2)Represents accruing TDR loans performing according to their restructured terms. 

At September 30, 2020 and December 31, 2019, troubled debt restructurings of $15.8 million and $18.6 million, respectively, were classified as accruing TDR loans. The restructurings were granted in response to borrower financial difficulty, and generally provide for a temporary modification of loan repayment terms. In order for a new TDR loan to be considered performing and on accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan must be current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow.

  

A further decline in the economic conditions due to the COVID-19 pandemic as well as in our general market areas or other factors could adversely impact individual borrowers or the loan portfolio in general. Accordingly, there can be no assurance that loans will not become 90 days or more past due, placed on non-accrual status, restructured or transferred to other real estate owned in the future. Umpqua is committed to helping borrowers during this unprecedented time of uncertainty and is working with customers on payment deferrals, forbearances, and other loan modifications.

COVID-19 Related Payment Deferrals and Forbearance

Due to the deterioration of the US economy resulting from the COVID-19 pandemic, the Company has had an increase in loan payment deferral and forbearance requests. Once a deferral or forbearance request is received, a late charge waiver is put in place and payments are suspended for up to six months. Accrued and unpaid interest during the deferral period will be collected upon the expiration of the deferral or on a regular repayment schedule at the end of the deferral period. For certain loan types, the maturity date may be extended one to six months to allow for full amortization. These loans are generally classified based on their past due status prior to their deferral period, so they are classified as performing loans that accrue interest.

A summary of outstanding loan balances with active payment deferral or forbearance as of September 30, 2020 are shown in the table below, disaggregated by major types of loans and leases:

			Loans with Deferrals or Forbearances
(dollars in thousands)			Number of Loans						Loan Balance Outstanding						% of Loan Portfolio

Consumer & other, net			125						2,467						0.8		%
Total			3,197						$	782,337					3.5		%

Included in the mortgage loans with payment deferrals or forbearance in the above table are $107.4 million of GNMA loans repurchased by the Bank from GNMA during the quarter, due to the fact that GNMA considers them delinquent and the Bank had the right to repurchase the loans.

The Bank continues to monitor COVID-19 deferrals and if a customer continues to experience financial difficulty after the initial deferral and further concessions are granted, the loan will be reviewed to determine if a TDR designation is appropriate. As of October 31, 2020, the Company had $562.9 million in loans on deferral or forbearance, reflecting a positive trend as compared to loans with deferrals or forbearances as of September 30, 2020.

Allowance for Credit Losses

 

The ACL totaled $369.4 million at September 30, 2020, an increase of $206.6 million from $162.7 million at December 31, 2019. The following table shows the activity in the ACL for the three and nine months ended September 30, 2020 and 2019: 

						Three Months Ended												Nine Months Ended

Recoveries as a percentage of charge-offs						19.01		%				22.08		%				15.20		%				21.28		%

(1) For comparability, the provision for credit losses as a percentage of average loans and leases annualized includes both the provision for loan and lease losses and the provision for unfunded commitments in prior periods.

(2) The total provision for credit losses disclosed in this table does not include the recapture or provision related to accrued interest on loans deferred due to COVID-19, which is included in the provision for credit losses in the income statement for the three and nine months ended September 30, 2020.

With the adoption of CECL, we recorded a one-time cumulative-effect pre-tax adjustment in the amount of $53.2 million. The allowance for credit losses on loans and leases increased by $50.0 million and the allowance for unfunded commitments increased by $3.2 million, resulting in a January 1, 2020, or day 1, balance of the Allowance for Credit Losses of $216.0 million.

The recapture of or provision for credit losses includes the provision for loan and lease losses, provision (recapture) for unfunded commitments, and the (recapture) provision for credit losses related to accrued interest on loans deferred due to COVID-19. The recapture of credit losses was $338,000 for the three months ended September 30, 2020. The provision for credit losses was $204.8 million for the nine months ended September 30, 2020. The decrease from $23.5 million for the three months ended September 30, 2019 was due to the stabilization of credit quality metrics and economic forecasts used in credit models as compared to prior periods in 2020, along with the decline in loan balances as compared to September 30, 2019. In addition, the Bank used CECL in the current year, but incurred loss in the prior year. CECL is expected to cause the provision for credit losses to be more volatile as we now reflect current expected credit losses, instead of incurred losses. The increase from $56.8 million for the nine months ended September 30, 2019 was principally attributable to the COVID-19 pandemic and its impact on the forecasts used to determine the expected credit losses of the loan and lease portfolio in the current year.

The following table sets forth the allocation of the allowance for credit losses on loans and leases and percent of loans in each category to total loans and leases as of September 30, 2020 and December 31, 2019: 

			September 30, 2020												December 31, 2019

The following table shows the change in the allowance for credit losses from June 30, 2020 to September 30, 2020:

						June 30, 2020						Q3 2020 net charge-offs						(Release)/ reserve build						September 30, 2020						% of Loan and Leases Outstanding
Commercial real estate						$	173,636					$	61					$	(19,214)					$	154,483					1.51		%

% of Loans and leases outstanding						1.69		%																1.65		%
% of Loans and leases outstanding - excluding PPP Loans						1.85		%																1.81		%

(1) The total allowance for credit losses disclosed in this table does not include the recapture or provision related to accrued interest on loans deferred due to COVID-19, which is included in the provision for credit losses in the income statement for the three and nine months ended September 30, 2020.

To calculate the ACL, the models use a forecast of future economic conditions and are dependent upon specific macroeconomic variables that are relevant to each of the Bank's loan and lease portfolios. For the third quarter the Bank used Moody's August Consensus forecast; key components include a US economy experiencing strong growth, then slow growth thereafter, GDP growth of 6.6% from Q2-Q4 2020, and unemployment rate of 10.7% in Q3 2020 with a return to less than 5% unemployment by 2024. The models for calculating the ACL are sensitive to changes in these and other economic variables, which could result in volatility as these assumptions change over time. In addition, the forward-looking assumptions revert to historical data when they reach the point where future assumptions are no longer estimated.

Within the ACLL as of September 30, 2020, we had a qualitative overlay of $40.6 million related to loans and leases, which is above and beyond the model results. The majority of this overlay resulted from approximately $20.0 million in small ticket leases that are past due greater than 60 days after completing their deferral period. These will most likely result in an increase in charge-offs in the next quarter, but have already been fully reserved for in the ACL.

We believe that the allowance for credit losses as of September 30, 2020 is sufficient to absorb losses inherent in the loan and lease portfolio and in credit commitments outstanding as of that date based on the information available. If the economic conditions continue to decline, the Bank may need additional provisions for credit losses in future periods.

Residential Mortgage Servicing Rights 

 

The following table presents the changes in our residential mortgage servicing rights portfolio for the three and nine months ended September 30, 2020 and 2019:  

			Three Months Ended												Nine Months Ended
(in thousands)			September 30, 2020						September 30, 2019						September 30, 2020						September 30, 2019
Balance, beginning of period			$	96,356					$	139,780					$	115,010					$	169,025
Additions for new MSR capitalized			14,014						7,393						37,484						16,772
Changes in fair value:
Changes due to collection/realization of expected cash flows over time			(4,878)						(6,835)						(15,249)						(20,171)
Changes due to valuation inputs or assumptions (1)			(12,244)						11,045						(43,997)						(14,243)
Balance, end of period			$	93,248					$	151,383					$	93,248					$	151,383

(1)The changes in valuation inputs and assumptions principally reflect changes in discount rates and prepayment speeds, which are primarily affected by changes in interest rates.

Information related to our residential serviced loan portfolio as of September 30, 2020 and December 31, 2019 was as follows: 

(dollars in thousands)			September 30, 2020						December 31, 2019
Balance of loans serviced for others			$	12,964,361					$	12,276,943
MSR as a percentage of serviced loans			0.72		%				0.94		%

Mortgage servicing rights are adjusted to fair value quarterly with the change recorded in mortgage banking revenue. The value of servicing rights can fluctuate based on changes in interest rates and other factors. Generally, as interest rates decline and borrowers are able to take advantage of a refinance incentive, prepayments increase and the total value of existing servicing rights declines as expectations of future servicing fees collections decline. Mortgage refinance volumes remain elevated due to low mortgage rates during the current periods, which caused accelerated prepayments and higher expectations for prepayment speeds in the future.

The fair value of the MSR asset decreased by $12.2 million and $44.0 million, respectively, for the three and nine months ended September 30, 2020, due to changes to inputs in the valuation model including changes in discount rates and prepayment speeds, which was due to decreases in the long term interest rates during the period. The fair value of the MSR asset decreased $4.9 million and $15.2 million, respectively, due to the passage of time, including the impact of regularly scheduled repayments, paydowns and payoffs during the three and nine months ended September 30, 2020.

 

Goodwill

 

At September 30, 2020 and December 31, 2019, the Company had goodwill of $2.7 million and $1.8 billion, respectively. Goodwill is recorded in connection with business combinations and represents the excess of the purchase price over the estimated fair value of the net assets acquired. Goodwill impairment of $1.8 billion was recorded as of March 31, 2020, due to an interim impairment analysis triggered by the decline in interest rates and economic impacts of COVID-19, as well as declines in the Company's stock price. The impairment was a result of market volatility and forecasts for a prolonged low interest rate environment, as well as higher credit losses expected due to the forecasted economic downturn.

Deposits 

Total deposits were $24.7 billion at September 30, 2020, an increase of $2.2 billion, as compared to December 31, 2019. The increase is mainly attributable to growth in non-interest bearing demand deposits, offset by a decline in time deposits. The increase in non-maturity deposit account categories is driven by increased customer savings rates as customers look to increase their own liquidity in this uncertain environment, in addition, the increase is attributable to the impact of economic assistance payments. The decrease in time deposits is mainly due to lower brokered deposits as the Company has allowed these higher-cost deposits to runoff, as well as the Company reducing its exception pricing on customer money market and time deposits.

The Company's brokered deposits totaled $523.2 million at September 30, 2020, compared to $1.2 billion at December 31, 2019.  

Borrowings 

 

At September 30, 2020, the Bank had outstanding $388.0 million of securities sold under agreements to repurchase, an increase of $76.7 million from December 31, 2019. The Bank had outstanding borrowings consisting of advances from the FHLB of $1.0 billion at September 30, 2020, which increased $89.9 million from December 31, 2019; the increase is attributable to additional borrowing activity primarily driven by the Company's liquidity strategy. The FHLB advances are secured by investment securities and loans secured by real estate. The FHLB advances have fixed interest rates ranging from 0.60% to 7.10% and mature in 2020 through 2030.

Junior Subordinated Debentures 

 

We had junior subordinated debentures with carrying values of $335.4 million and $363.3 million at September 30, 2020 and December 31, 2019, respectively.  The decrease is mainly due to the $26.9 million decline in fair value for the junior subordinated debentures elected to be carried at fair value, which is due mostly to an increase in the credit spread, and the implied forward curve shifting lower. As of September 30, 2020, substantially all of the junior subordinated debentures had interest rates that are adjustable on a quarterly basis based on a spread over three month LIBOR.  

Liquidity and Cash Flow 

 

The principal objective of our liquidity management program is to maintain the Bank's ability to meet the day-to-day cash flow requirements of our customers who either wish to withdraw funds or to draw upon credit facilities to meet their cash needs. The Bank's liquidity strategy was adjusted to adopt an elevated on-balance sheet liquidity position to further enhance flexibility due to the increased market volatility and uncertainty as a result of the COVID-19 pandemic. As a result, the Company believes that it has sufficient cash and access to borrowings to effectively manage through the COVID-19 pandemic as well as meet its working capital and other needs. The Company will continue to prudently evaluate and expand liquidity sources, including the management of availability and utilization of our borrowing sources.

We monitor the sources and uses of funds on a daily basis to maintain an acceptable liquidity position. One source of funds includes public deposits. Individual state laws require banks to collateralize public deposits, typically as a percentage of their public deposit balance in excess of FDIC insurance.  Public deposits represented 7% of total deposits at September 30, 2020 and 9% of total deposits at December 31, 2019. The amount of collateral required varies by state and may also vary by institution within each state, depending on the individual state's risk assessment of depository institutions. Changes in the pledging requirements for uninsured public deposits may require pledging additional collateral to secure these deposits, drawing on other sources of funds to finance the purchase of assets that would be available to be pledged to satisfy a pledging requirement, or could lead to the withdrawal of certain public deposits from the Bank. In addition to liquidity from core deposits and the repayments and maturities of loans and investment securities, the Bank can utilize established uncommitted federal funds lines of credit, sell securities under agreements to repurchase, borrow on a secured basis from the FHLB or issue brokered certificates of deposit.

Table of Contents

The Bank had available lines of credit with the FHLB totaling $6.3 billion at September 30, 2020, subject to certain collateral requirements, namely the amount of pledged loans and investment securities. The Bank had available lines of credit with the Federal Reserve totaling $456.4 million, subject to certain collateral requirements, namely the amount of certain pledged loans. The Bank had uncommitted federal funds line of credit agreements with additional financial institutions totaling $460.0 million at September 30, 2020. Availability of these lines is subject to federal funds balances available for loan and continued borrower eligibility. These lines are intended to support short-term liquidity needs, and the agreements may restrict consecutive day usage. 

 

The Company is a separate entity from the Bank and must provide for its own liquidity. Substantially all of the Company's revenues are obtained from dividends declared and paid by the Bank. There were $163.0 million of dividends paid by the Bank to the Company in the nine months ended September 30, 2020.  There are statutory and regulatory provisions that limit the ability of the Bank to pay dividends to the Company. The Company recorded a net loss of $7.60 per diluted common share for the nine months ended September 30, 2020, due to a $1.8 billion goodwill impairment charge recorded during the period. As a result, the Company has an accumulated deficit, instead of retained earnings at September 30, 2020.

Due to the accumulated deficit, the Company is required to notify the Board of Governors of the Federal Reserve System ("FRB") prior to declaring and paying a cash dividend to our shareholders and may not pay a dividend if the FRB objects. Additionally, the Company will be required to seek FDIC and Oregon Division of Financial Regulation approval for quarterly dividends from Umpqua Bank to the Company. In the second quarter, the Company changed the timing of its dividend to shareholders from an intra-quarter announcement to after quarterly earnings are released. The shift in announcement timing was made to provide the Company’s Board of Directors and regulators the opportunity to review final quarterly financial results and financial projections prior to approval of any dividends. The Company expects to continue this cadence for dividend payments in future quarters.

 

As disclosed in the Condensed Consolidated Statements of Cash Flows, net cash used in operating activities was $81.0 million during the nine months ended September 30, 2020, with the difference between cash used in operating activities and net loss consisting primarily of goodwill impairment of $1.8 billion, proceeds from the sale of loans held for sale of $5.0 billion, provision for loan and lease losses of $204.8 million, offset by originations of loans held for sale of $4.9 billion, the increase in other assets of $231.8 million, and the gain on sale of loans of $212.4 million. This compares to net cash used in operating activities of $77.9 million during the nine months ended September 30, 2019, with the difference between cash provided by operating activities and net income consisting of originations of loans held for sale of $2.0 billion, the increase in other assets of $179.3 million, gain on equity securities of $83.6 million, and gain on sale of loans of $65.7 million, offset by proceeds from the sale of loans held for sale of $1.9 billion, provision for loan and lease losses of $56.3 million, a loss on fair value of residential mortgage servicing rights carried at fair value of $34.4 million, and depreciation, amortization and accretion of $33.1 million.

Net cash of $1.4 billion used in investing activities during the nine months ended September 30, 2020, consisted principally of net loan originations of $1.3 billion, purchases of available for sale investment securities of $595.4 million, and net cash paid in divestiture of stores of $81.2 million, offset by proceeds from available for sale investment securities of $604.6 million and the proceeds from sales of loans of $60.8 million. This compares to net cash of $908.9 million used in investing activities during the nine months ended September 30, 2019, which consisted principally of net loan originations of $1.2 billion, purchases of available for sale investment securities of $563.6 million, purchases of restricted equity securities of $220.2 million and net cash paid in divestiture of a store of $44.6 million, offset by proceeds from available for sale investment securities of $778.3 million, redemption of restricted equity securities of $206.0 million, proceeds from the sale of loans and leases of $88.8 million and proceeds from sale of equity securities of $81.9 million.

Net cash of $2.3 billion provided by financing activities during the nine months ended September 30, 2020, primarily consisted of $2.3 billion net increase in deposits and proceeds from borrowings of $600.0 million, offset by $510.0 million repayment of borrowings and $138.7 million of dividends paid on common stock. This compares to net cash of $1.6 billion provided by financing activities during the nine months ended September 30, 2019, which consisted primarily of $1.3 billion net increase in deposits and proceeds from borrowings of $810.7 million, offset by $455.7 million repayment of borrowings and $138.9 million of dividends paid on common stock.

Although we expect the Bank's and the Company's liquidity positions to remain satisfactory during 2020, it is possible that our deposit growth may not be maintained at previous levels due to pricing pressure, store consolidations, or customers' spending habits due to the COVID-19 pandemic. In addition, in order to generate deposit growth, our pricing may need to be adjusted in a manner that results in increased interest expense on deposits.

Capital Resources 

 

Shareholders' equity at September 30, 2020 was $2.6 billion, a decrease of $1.7 billion from December 31, 2019. The decrease in shareholders' equity during the nine months ended September 30, 2020 was principally due to the net loss during the period, related mainly to the goodwill impairment as of March 31, 2020, and resulted in an accumulated deficit as of September 30, 2020.

The Company's dividend policy considers, among other things, earnings, regulatory capital levels, the overall payout ratio and expected asset growth to determine the amount of dividends declared, if any, on a quarterly basis. There is no assurance that future cash dividends on common shares will be declared or increased. We cannot predict the extent of the economic decline due to COVID-19 or other factors that result in inadequate earnings, regulatory restrictions and limitations, changes to our capital requirements, or a decision to increase capital by retention of earnings, that may result in the inability to pay dividends at previous levels, or at all.

Due to the accumulated deficit, the Company is required to notify the Board of Governors of the FRB prior to declaring and paying a cash dividend to our shareholders and may not pay a dividend if the FRB objects. Additionally, the Company will be required to seek FDIC and Oregon Division of Financial Regulation approval for quarterly dividends from Umpqua Bank to the Company. In the second quarter of 2020, the Company changed the timing of its quarterly dividend from an intra-quarter announcement to after quarterly earnings release. The shift in announcement timing was made to provide the Company’s Board of Directors and regulators the opportunity to review final quarterly financial results and financial projections, prior to the announcement of any dividend. The Company expects to continue this cadence in future quarters.

The following table presents cash dividends declared and dividend payout ratios (dividends declared per common share divided by basic earnings per common share) for the three and nine months ended September 30, 2020 and the three and nine months ended September 30, 2019.

			Three Months Ended												Nine Months Ended
			September 30, 2020						September 30, 2019						September 30, 2020						September 30, 2019
Dividend declared per common share			$	0.21					$	0.21					$	0.42					$	0.63
Dividend payout ratio			37		%				55		%				(6)		%				51		%

As of September 30, 2020, a total of 9.5 million shares are available for repurchase under the Company's current share repurchase plan. During the nine months ended September 30, 2020, 331,000 shares were repurchased under this plan. The Board of Directors approved an extension of the repurchase plan to July 31, 2021. The timing and amount of future repurchases will depend upon the market price for our common stock, securities laws restricting repurchases, asset growth, earnings, and our capital plan.  In addition, our stock plans provide that option and award holders may pay for the exercise price and tax withholdings in part or entirely by tendering previously held shares.

Along with enactment of the CARES Act, the federal bank regulatory authorities issued an interim final rule to provide banking organizations that are required to implement CECL before the end of 2020 the option to delay the estimated impact on regulatory capital by up to two years, with a three-year transition period to phase out the cumulative benefit to regulatory capital provided during the two-year delay. The Company has elected this capital relief and will delay the estimated regulatory capital impact of adopting CECL, relative to the incurred loss methodology's effect on regulatory capital.

Item 3.             Quantitative and Qualitative Disclosures about Market Risk 

 

Our assessment of market risk as of September 30, 2020 indicates there are no material changes in the qualitative disclosures from those in our Annual Report on Form 10-K for the year ended December 31, 2019. However due to the impact of declining interest rates resulting from the Federal Reserve monetary policy and programs, and market reaction to the economic impact of the COVID-19 pandemic, the estimated impact on our net interest income over a one-year time horizon has shifted.

Interest Rate Simulation Impact on Net Interest Income

As of September 30, 2020 and December 31, 2019 and 2018:

						September 30, 2020						December 31, 2019						December 31, 2018
Up 300 basis points						8.6		%				5.9		%				4.9		%
Up 200 basis points						5.9		%				4.1		%				3.3		%
Up 100 basis points						3.0		%				2.2		%				1.7		%
Down 100 basis points						(1.5)		%				(3.8)		%				(2.8)		%
Down 200 basis points						(2.1)		%				(7.4)		%				(6.3)		%
Down 300 basis points						(2.3)		%				(9.4)		%				(9.5)		%

For the scenarios shown, the interest rate simulation assumes a parallel and sustained shift in market interest rates ratably over a twelve-month period and no change in the composition or size of the balance sheet.

As rates have declined, our asset sensitivity in an increasing rate environment has increased. This is due to interest-bearing assets projected to reprice in greater velocity or magnitude in comparison to interest bearing liabilities, and also due to significant growth in non-interest bearing deposits which are not sensitive to changing interest rates in the simulation. In a declining rate environment, the reduced sensitivity, compared to year-end simulation results, reflects more interest-bearing assets at or near rate floors and the assumption that market interest rates do not go negative.

The short-term interest rate environment is primarily a function of the monetary policy of the FRB. The principal tools of the Federal Reserve for implementing monetary policy are open market operations, or the purchases and sales of U.S. Treasury and Federal agency securities, as well as the establishment of a short-term target rate. The Federal Reserve's objective for open market operations has varied over the years, but the focus has gradually shifted toward attaining a specified level of the federal funds rate to achieve the long-run goals of price stability and sustainable economic growth. The federal funds rate is the basis for overnight funding and drives the short end of the yield curve. Longer maturities are influenced by the market's expectations for economic growth and inflation, but are also influenced by Federal Reserve purchases and sales and expectations of monetary policy going forward.

In March 2020, in response to the COVID-19 pandemic, its effect on economic activity in the near term and the risk it poses to the economic outlook, the FOMC lowered the target range for the federal funds rate 150 basis points to 0.00% to 0.25%. At its September 2020 meeting the FOMC noted it expects to maintain an accommodating stance of monetary policy until the outcomes of maximum employment and inflation at a rate of 2% over the longer run is achieved. Maintaining the current level of the federal funds rate could cause overall interest rates to fall, which may negatively impact financial performance. Increases in the federal funds rate and the unwinding of its balance sheet could cause overall interest rates to rise, which may negatively impact the U.S. real estate markets and affect deposit growth and pricing. In addition, deflationary pressures, while possibly lowering our operating costs, could have a significant negative effect on our borrowers, especially our business borrowers, and the values of collateral securing loans, which could negatively affect our financial performance.

LIBOR Transition

In 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it would no longer require banks to submit rates for LIBOR after 2021. The Alternative Reference Rates Committee ("ARRC") is a group of private-market participants convened by the FRB and the New York Fed to help ensure a successful transition from U.S. dollar LIBOR to a more robust reference rate, its recommended alternative, the Secured Overnight Financing Rate. In addition, the ARRC has noted that though near-term interim steps in the transition may be delayed given the current economic environment with the global pandemic, it remains clear that the financial system should continue to move to transition by the end of 2021. The Company holds financial instruments that will be impacted by the discontinuance of LIBOR, primarily certain loans, derivatives, and junior subordinated debentures that use LIBOR as the benchmark rate. The Company anticipates these financial instruments will require transition to new reference rates. This transition will occur over time as many of these arrangements do not have an alternative rate referenced in their contracts. The Company has commenced an enterprise-wide transition program with program deliverables including business strategy, product design and pricing strategy, instrument contract remediation, and systems and processes. These deliverables include milestones that address operational changes, targeted communications and education planning, and to identify, assess, monitor and remediate risks associated with the transition.

Item 4.             Controls and Procedures 

 

Our management, including our Chief Executive Officer, Chief Financial Officer and Principal Accounting Officer, has concluded that our disclosure controls and procedures are effective in timely alerting them to information relating to us that is required to be included in our periodic filings with the SEC. The disclosure controls and procedures were last evaluated by management as of September 30, 2020. 

While we have incorporated additional controls related to our CECL accounting processes into our existing internal control environment, there was no change in internal control over financial reporting that occurred during the quarter ended September 30, 2020 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Part II. OTHER INFORMATION 

Item 1.      Legal Proceedings 

Due to the nature of our business, we are involved in legal proceedings that arise in the ordinary course of our business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

 

Item 1A.   Risk Factors 

 

In addition to the other information set forth in this report, you should carefully consider the factors discussed under "Part I--Item 1A--Risk Factors" in our Form 10-K for the year ended December 31, 2019. These factors could materially and adversely affect our business, financial condition, liquidity, results of operations and capital position, and could cause our actual results to differ materially from our historical results or the results contemplated by the forward-looking statements contained in this report. Other than as described below, there have been no other material changes from the risk factors described in our Form 10-K.

The COVID-19 pandemic has adversely impacted our business and financial results, and the ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

The COVID-19 pandemic has negatively impacted the economy, changed customer behaviors, disrupted supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. The pandemic has resulted in temporary and long-term closures of many businesses and the institution of social distancing and stay at home/sheltering in place requirements in the states and communities we serve. As a result, the demand for our products and services may be significantly impacted, which could adversely affect our revenue. The pandemic could continue to result in the recognition of credit losses in our loan portfolios and increases in our allowance for credit losses, particularly if businesses remain closed, unemployment levels continue to rise, regional economic conditions worsen, or government stimulus programs are scaled back or eliminated. Our business operations may also be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic. In response to the pandemic, we have initiated relief programs designed to support our customers and communities including payment deferral programs, deferral-related and other fee waivers, suspended residential property foreclosure sales, and other expanded assistance for customers. Future governmental actions may require additional types of customer-related responses that could negatively impact our financial results. We could be required to take capital actions in response to the COVID-19 pandemic, including reducing dividends and eliminating stock repurchases. The extent to which the COVID-19 pandemic continues to impact our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic; actions taken by governmental authorities and other third parties in response to the pandemic; the effect on our customers, counterparties, employees and third party service providers; and the effect on economies and markets. To the extent that the COVID-19 pandemic continues to adversely affect our business and financial performance, it may also have the effect of heightening many of the other risks identified in the "Risk Factors" section of our most recently filed Annual Report on Form 10-K.

We have adopted new accounting guidance, specifically CECL, to account for our credit losses that may be more volatile and may adversely impact our financial statements when forecasted market conditions change.

In January 2020, the Company adopted the FASB Accounting Standard Update, "Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," which replaces the previous "incurred loss" model for recognizing credit losses with an "expected loss" model referred to as CECL. Under CECL, we are required to present certain financial assets carried at amortized cost, such as loans and leases held for investment, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model, which delays recognition until it is probable a loss has been incurred. CECL may create more volatility in the level of our allowance for credit losses.

Summary of Significant Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies    The accounting and financial reporting policies of Umpqua Holdings Corporation conform to accounting principles generally accepted in the United States of America ("GAAP"). All references in this report to "Umpqua," "we," "our," "us," the "Company" or similar references mean Umpqua Holdings Corporation and include our consolidated subsidiaries where the context so requires. References to "Bank" refer to our subsidiary Umpqua Bank, an Oregon state-chartered commercial bank, and references to "Umpqua Investments" refer to our subsidiary Umpqua Investments, Inc., a registered broker-dealer and investment adviser. The Bank also has a wholly-owned subsidiary, Financial Pacific Leasing, Inc. ("FinPac"), a commercial equipment leasing company. The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.  All inter-company balances and transactions have been eliminated. The condensed consolidated financial statements have not been audited. A more detailed description of the Company's accounting policies is included in the 2019 Annual Report filed on Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2019 Annual Report filed on Form 10-K.  The results for interim periods are not necessarily indicative of results for the full year or any other interim period. As of September 30, 2020, the impact of the novel coronavirus ("COVID-19") continues to unfold and many of the Company's estimates and assumptions require increased judgment and carry a higher degree of variability and volatility, including the provision for credit losses which has been materially impacted. The Company is unable to fully predict the impact that COVID-19 will have on its financial position and results of operations due to numerous uncertainties and will continue to assess the potential impacts on its financial position and results of operations. As events continue to evolve and additional information becomes available, estimates may change materially in future periods. In preparing these condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to September 30, 2020 for potential recognition or disclosure. In management's opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. Certain reclassifications of prior period amounts have been made to conform to current classifications. Application of new accounting guidance In June 2016, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments —Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL" or "ASC 326"). CECL is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. ASC 326 requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, ASC 326 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The adoption date for the Company was January 1, 2020. The guidance was applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at January 1, 2020. However, certain provisions of the guidance are only required to be applied on a prospective basis. The Bank has elected to not include accrued interest when determining the amortized cost basis of an asset. Instead, the amortized cost basis of an asset is the combination of the balance, deferred fees and costs, and premium or discount. In addition, the Bank has elected to continue to present accrued interest as part of Other Assets on the consolidated balance sheets. The Bank has calculated an allowance for credit losses on accrued interest that is included with the accrued interest balance. The policies related to income recognition on non-accrual loans are outlined below. Upon adoption of CECL, the Company did not reassess whether loans previously accounted for as purchased credit impaired ("PCI") met the definition of a Purchased Credit-Deteriorated ("PCD") loan and therefore accounts for all such assets as PCD. The Company has elected not to retain the PCI pools previously established. Instead, the loans will now be included within the appropriate class of financing receivables which have been established based on shared risk characteristics. Changes to the allowance after adoption are recorded through provision expense. Based on the Bank's portfolio composition as of January 1, 2020, and the economic environment at that time, management recorded an initial estimate of the allowance for credit losses ("ACL") under CECL, which includes the allowance for credit losses on loans and leases ("ACLLL") of $207.6 million and the reserve for unfunded commitments ("RUC") of $8.3 million. The implementation of CECL resulted in a cumulative effect of an accounting change adjustment to retained earnings of $40.2 million. The Company analyzed the portfolio segments and classes of financing receivables based on the implementation of CECL. There were no necessary changes in the portfolio segments or classes of financing receivables. The increase in the allowance by portfolio segment was as follows: December 31, 2019 January 1, 2020 (in thousands) Allowance for Loan and Lease Losses Reserve for Unfunded Commitments Allowance for Credit Losses on Loans and Leases Reserve for Unfunded Commitments $ Increase (decrease) % Increase (decrease) Commercial real estate, net $ 50,847  $ 534  $ 55,924  $ 4,564  $ 9,107  18  % Commercial, net 73,820  2,539  117,829  2,052  43,522  57  % Residential, net 24,714  149  26,813  1,416  3,366  14  % Consumer & other, net 8,248  1,884  7,062  312  (2,758) (27) % Total $ 157,629  $ 5,106  $ 207,628  $ 8,344  $ 53,237  33  % Due to the significance of the implementation of CECL on the Company, the following significant accounting policies have been updated from the policies described in the 2019 Annual Report filed on Form 10-K. Allowance for Credit Losses Policy- The Bank has established an Allowance for Credit Loss Committee, which is responsible for, among other things, regularly reviewing the ACL methodology, including allowance levels and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The Bank's Audit and Compliance Committee provides board oversight of the ACL process and reviews and approves the ACL methodology on a quarterly basis. CECL is not prescriptive in the methodology used to determine the expected credit loss estimate. Instead, management has flexibility in selecting the methodology. The expected credit losses must be estimated over a financial asset's contractual term, adjusted for prepayments utilizing quantitative and qualitative factors. There are also specific considerations for PCD, Troubled Debt Restructured ("TDR"), and Collateral Dependent Loans ("CDL"). The estimate of current expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms, and differences in economic conditions – both current conditions and reasonable and supportable forecasts. When the Company is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it has estimated expected credit losses for the remaining life using an approach that reverts to historical credit loss information for the longer-term portion of the asset's life. The Company utilizes complex models to obtain reasonable and supportable forecasts; most of the models calculate two predictive metrics: the probability of default ("PD") and loss given default ("LGD"). The PD measures the probability that a loan will default within a given time horizon and primarily measures the adequacy of the debtor's cash flow as the primary source of repayment of the loan or lease. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral. The combination of the current expected credit loss, PCD, CDL, TDR, and the RUC components represent the ACL. Management believes that the ACL was adequate as of September 30, 2020. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could possibly result in additional charges to the provision for credit losses. Acquired Loans and Leases- Loans and leases purchased without more-than-insignificant credit deterioration, are recorded at their fair value at the acquisition date. However, loans and leases purchased with more-than-insignificant credit deterioration will be recorded with their applicable allowance for credit loss to determine the amortized cost basis. Originated Loans and Leases- Loans are stated at the amount of unpaid principal, net of unearned income and any deferred fees or costs. All discounts and premiums are recognized over the contractual life of the loan as yield adjustments. Leases are recorded at the amount of minimum future lease payments receivable and estimated residual value of the leased equipment, net of unearned income and any deferred fees. Initial direct costs related to lease originations are deferred as part of the investment in direct financing leases and amortized over their term using the effective interest method. Unearned lease income is amortized over the term using the effective interest method. Income Recognition on Non-Accrual Loans- Loans are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a commercial or commercial real estate loan is past due beyond its maturity or principal or interest payment due date by 90 days or more, unless such loans are well-secured and in the process of collection. Loans that are less than 90 days past due may also be classified as non-accrual if repayment in full of principal and/or interest is in doubt. Generally, when a loan is classified as non-accrual, all uncollected accrued interest is reversed from interest income and the accrual of interest income is terminated. In addition, any cash payments subsequently received are applied as a reduction of principal outstanding. In cases where the future collectability of the principal balance in full is expected, interest income may be recognized on a cash basis. A loan may be restored to accrual status when the borrower's financial condition improves so that full collection of future contractual payments is considered likely. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will typically not occur until the borrower demonstrates repayment ability over a period of not less than six months. Collateral Dependent Loans and Troubled Debt Restructurings- A loan or lease is considered collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. The Company's classification of CDLs includes: non-homogeneous non-accrual loans and leases; non-homogeneous loans determined by individual credit review; homogeneous non-accrual leases and equipment finance agreements; and homogeneous real estate secured loans that have been charged down to net realizable value or the government guaranteed balance. Except for homogeneous leases and equipment finance agreements, the expected credit losses for CDLs will be measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. The Company may also use the loan's observable market price, if available. If the value of the CDL is determined to be less than the recorded amount of the loan, a charge-off will be taken. To determine the expected credit loss for homogeneous leases or equipment finance agreements, the LGD calculated by the CECL model will be utilized. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is fully charged-off. Loans are reported as TDR loans when, due to borrower financial difficulties, the Bank grants a concession it would not otherwise be willing to offer for a loan. Once a loan has been classified as a TDR, it continues in the classification until it has paid in full or it has demonstrated six months of payment performance and was determined to have been modified at a market rate terms. TDRs, including reasonably expected TDRs, are individually recognized and measured for expected credit loss in one of two ways: when a TDR meets the definition of a CDL, it is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable; otherwise, a discounted cash flow analysis is utilized to measure the expected credit loss for a TDR. The expected cash flow for a TDR is discounted based on the pre-modification rate and the expected remaining life. In March 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was passed, which, among other things, provided relief for Banks related to loan modifications for accounting purposes. Specifically, section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for TDRs. In addition to the CARES Act, bank regulatory agencies issued interagency guidance indicating that a lender could conclude that the modifications under section 4013 of the CARES Act or the interagency guidance are not a TDR if certain criteria are met. The guidance also provides that loans generally will not be adversely classified if the short-term modification is related to COVID-19 relief programs. The Company has followed the guidance under the CARES Act and the interagency guidance related to these loan modifications. Loans modified under section 4013 of the CARES Act or the interagency guidance generally maintain their pre-COVID-19 delinquency status and are classified as performing loans. If it is deemed the modification is not short-term, not COVID-19 related or the customer does not meet the criteria under the guidance to be scoped out of troubled debt restructuring classification, the Company evaluates the loan modifications under its existing framework which requires modifications that result in a concession without appropriate compensation to a borrower experiencing financial difficulty to be accounted for as a TDR. Reserve for Unfunded Commitments- A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb expected losses associated with the Bank's commitment to lend funds under existing agreements, such as letters or lines of credit. The RUC calculation utilizes the allowance for credit loss on loans and leases rates, probability of default risk ratings, and utilization rates based on the economic expectations over the contractual life of the commitment. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and adjustments are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on loans and leases. Provisions for unfunded commitment losses are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets. Investment Securities Available for Sale- Debt securities are classified as available for sale if the Company intends and has the ability to hold those securities for an indefinite period of time, but not necessarily to maturity. Any decision to sell a debt security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned. Securities available for sale are carried at fair value. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Unrealized holding gains or losses are included in other comprehensive income ("OCI") as a separate component of shareholders' equity, net of tax. When the fair value of an available-for-sale debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. Decreases in fair value attributable to credit loss would be recorded directly to earnings with a corresponding allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves the allowance would be reversed up to a maximum of the previously recorded credit losses. If the Company intends to sell an impaired available-for-sale debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment would be immediately recognized in earnings with no corresponding allowance for credit losses. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. This ASU was issued to improve the effectiveness of disclosures surrounding fair value measurements. The ASU removes numerous disclosures from Topic 820 including: transfers between level 1 and 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation process for level 3 fair value measurements. The ASU also modified and added disclosure requirements in regards to changes in unrealized gains and losses included in other comprehensive income, as well as the range and weighted average of unobservable inputs for level 3 fair value measurements. The Company adopted this ASU as of January 1, 2020, on a retrospective basis except certain provisions of the guidance which are only required to be applied on a prospective basis. Recent accounting pronouncements  In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. The expedients are in effect from March 12, 2020, through December 31, 2022. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements.

In response to the COVID-19 crisis, the federal government created the Paycheck Protection Program ("PPP"), sponsored by the Small Business Administration ("SBA"), under the CARES Act. The Bank participated in the PPP to originate SBA loans designated to help businesses maintain their workforce and cover other working capital needs during the COVID-19 pandemic by funding 16,900 loans, totaling $2.0 billion in net loans, which are classified as commercial term loans. Net deferred costs are offset by $51.2 million in PPP loan related fees net of costs, which will be a yield adjustment over the remaining term of these loans. The loans are fully guaranteed by the SBA and the maximum term of the loans is either two or five years; however, the majority of the loan balances are expected to be forgiven by the SBA. Net loans also include discounts on acquired loans of $20.7 million and $30.2 million as of September 30, 2020 and December 31, 2019, respectively. As of September 30, 2020, loans totaling $12.7 billion were pledged to secure borrowings and available lines of credit. The Company elected to exclude accrued interest receivable from the amortized cost basis of loans disclosed throughout this footnote. Interest accrued on loans totaled $70.9 million and $58.5 million as of September 30, 2020 and December 31, 2019, respectively, and is included in Other Assets. The Bank, through its commercial equipment leasing subsidiary, FinPac, is a provider of commercial equipment leasing and financing. Direct finance leases are included within the lease and equipment finance segment within the loans and leases, net line item. These leases typically have terms of three to five years and are considered to be direct financing leases. Interest income recognized on these leases was $6.7 million and $20.5 million for the three and nine months ended September 30, 2020, respectively, as compared to $8.1 million and $24.6 million for the three and nine months ended September 30, 2019, respectively.

Allowance for Credit Losses	9 Months Ended
	Sep. 30, 2020
Receivables [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses Allowance for Credit Losses Methodology The Allowance for Credit Losses is an important element in the Bank's financial statements. In accordance with CECL, the ACL represents management's estimate of lifetime credit losses for assets within its scope, specifically loans and leases and unfunded commitments. To calculate the ACL, management uses models to estimate the PD and LGD for loans utilizing inputs that include forecasted future economic conditions and that are dependent upon specific macroeconomic variables relevant to each of the Bank's loan and lease portfolios. Moody's Analytics, a third party, provided the historical and forward-looking macroeconomic data used in the development of the models used to calculate the ACL. For ACL calculation purposes, the Bank considered the financial and economic environment at the time of assessment and economic scenarios that differed in the levels of severity and sensitivity to the ACL results. At each measurement date, the Bank selects the scenario that reflects its view of future economic conditions and is determined to be the most probable outcome. All forecasts are updated for each variable where applicable and incorporated as relevant into the ACL calculation. Actual credit loss results will differ from the estimate of credit losses, either in a strong economy or a recession, as our portfolio will change through time due to growth, risk mitigation actions and other factors. In addition, the scenarios used will differ and change through time as economic conditions change. Economic scenarios might not capture deterioration or improvement in the economy timely enough for the Bank to be able to adequately assess the impact to the ACL. Select macroeconomic variables are projected over the forecast period, and they could have a material impact in determining the ACL. As the length of the forecast period increases, information about the future becomes less readily available and projections are inherently less certain. The following is a discussion of the changes in the factors that influenced management's current estimate of expected credit losses. The changes in the ACL estimate for all portfolio segments, during the three and nine months ended September 30, 2020, were primarily related to changes in the economic assumptions. The Bank opted to use Moody's Analytics August consensus economic forecast for estimating the ACL as of September 30, 2020. This scenario is based on Moody's Analytics review of a variety of surveys of baseline forecasts of the U.S. economy. These surveys vary in date of latest vintage, number of updates per year, list of variables forecast, duration of forecast, frequency of data (quarterly or annual), and the number of respondents to a survey. In the preparation of the Moody's Analytics consensus forecast, the focus is on the next three to five years, since that is the most typical duration in the surveyed results. Moody's Analytics approach is to give greater consideration to whatever forecasts were produced most recently, since they will include the most up-to-date historical information, and to those variables for which the number of surveyed responses is largest. In the consensus scenario selected, the probability that the economy will perform better than this consensus is equal to the probability that it will perform worse and included the following factors: •U.S. real GDP growth begins to decrease after the strong recovery but continues to be positive over both the short and long-term; •U.S. unemployment rate average of 10.7% in the third quarter of 2020 and is expected to be 9.3% in the fourth quarter of 2020; •very strong recovery with sustained growth in the fourth quarter of 2020, and continued slow growth thereafter; •return to less than 5% unemployment by 2024. The Bank uses an additional scenario that differs in terms of severity within the variables, both favorable and unfavorable, to assess sensitivity in the ACL results and to inform qualitative adjustments. The Bank selected the Moody's Analytics August S2 scenario for this analysis. In the scenario selected, there is a 75% probability that the economy will perform better, broadly speaking, and a 25% probability that it will perform worse; and the scenario includes the following factors: •rising business bankruptcies and reduced consumer and business sentiment cause the economy to stall over the next several quarters; •slow real GDP growth through 2021 with increases thereafter; •U.S. unemployment rate average of 10.2% in the third quarter of 2020 and is expected to be 10.4% in the fourth quarter of 2020; •very strong recovery in the current quarter of 2020, with substantially slower growth after the current quarter through the second quarter of 2021, then gradually increasing growth thereafter; •return to less than 5% unemployment by 2025. The results using the comparison scenario for sensitivity analysis were reviewed by management, but management believes the consensus scenario better reflects the estimated economic environment. The ACL is measured on a collective (pool) basis when similar characteristics exist. The Company has selected models at the portfolio level using a risk-based approach, with larger, more complex portfolios having more complex models. Except as noted below, the macroeconomic variables that are inputs to the models are reasonable and supportable over the life of the loans in that they reasonably project the key economic variables in the near term and then converge to a long run equilibrium trend. These models produce reasonable and supportable estimates of loss over the life of the loans as the projected credit losses will also converge to a steady state in line with the variables applied. The Company measures the ACL using the following methods: Commercial Real Estate ("CRE"): Non-owner occupied commercial real estate, multifamily, and construction loans are analyzed using a model that uses four primary property variables: Net Operating Income ("NOI"), Property Value, Property Type, and Location. For PD estimation, the model simulates potential future paths of NOI given commercial real estate market factors determined from macroeconomic forecasts. Using the resulting expected debt service coverage ratios, together with predicted loan-to-values and other variables, the model estimates PD from the range of conditional possibilities. In addition, the model estimates maturity PD capturing refinance default risk to produce a total PD for the loan. The model estimates LGD, inclusive of principal loss and liquidation expenses, empirically using predicted loan-to-value as well as certain market and other factors. The LGD calculation also includes a separate maturity risk component. The primary economic drivers in the model are GDP Growth, U.S. unemployment rate, and 10-Year Treasury yield. The model produces PD and LGD on a quarter-by-quarter basis for the life of loan. The owner-occupied commercial real-estate portfolio utilizes a top down macroeconomic model using linear regression. This model produces portfolio level quarterly net charge-off rates for 10 years. The primary economic drivers for this model are the 7-year A vs Aa corporate bond spread and S&P 500 corporate after-tax profits. Commercial: Non-homogeneous commercial loans and leases and residential development loans are analyzed in a multi-step process. An initial PD is estimated using a model driven by an obligor's selected financial statement ratios, together with cycle-adjusting information based on the obligor's state and industry. An initial LGD is derived separately based on collateral type using collateral value and a haircut to reflect the loss in liquidation. Another model then applies an auto-regression technique to the initial PD and LGD metrics to estimate the PD and LGD curves according to the macroeconomic scenario over a one-year reasonable and supportable forecast. The primary economic drivers in the model are the S&P 500 Stock Price Index, S&P 500 Market Volatility Index, U.S. unemployment rate, as well as appropriate yield curves and credit spreads. This model utilizes output reversion methodology, which, after one year, reverts on a straight-line basis over two years to long-term PD estimated using financial statement ratios of each obligor. The model for the homogeneous lease and equipment finance agreement portfolio uses lease and equipment finance agreement information, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD values. The PD calculation is based on survival analysis while LGD is calculated using a two-step regression. The model calculates LGD using an estimate of the probability that a defaulted lease or equipment finance agreement will have a loss, and an estimate of the loss amount. The primary economic drivers for the model are GDP, U.S. unemployment rate, and a home price growth index. The model produces PD and LGD curves at the lease level for each month in the forecast horizon. Residential: The models for residential real estate and Home Equity Lines of Credit ("HELOC") utilize loan level variables, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD. The U.S. unemployment rate and home price growth rate indexes are primary economic drivers in both the residential real estate and HELOC models. In addition, the prime rate is also a primary driver in the HELOC model. The models focus on establishing an empirical relationship between default probabilities and a set of loan-level, borrower, and macroeconomic credit risk drivers. The LGD calculation for residential real estate is based on an estimate of the probability that a defaulted loan will have a loss, and then an estimate of the loss amount. HELOCs utilize the same model using residential real estate LGD values to assign loans to cohorts based on FICO scores and loan age. The model produces PD and LGD curves at the loan level for each quarter in the forecast horizon. Consumer: Historical net charge-off information as well as economic forecast assumptions are used to project loss rates for the Consumer segment. All loans and leases that have not been modeled receive a loss rate via an extrapolated rate methodology. The loans and leases receiving an extrapolated rate are typically newly originated loans and leases or loans and leases without the granularity of data necessary to be modeled. Based on the vintage year, credit classification, and reporting category of the modeled loans and leases, a loss factor is calculated and applied to the non-modeled loans and leases. Along with the quantitative factors produced by the above models, management also considers prepayment speeds and qualitative factors when determining the ACL. The Company uses a prepayment model that forecasts the constant prepayment rates based on institution specific data. Below are the nine qualitative factors considered where applicable: •Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses. •Changes in national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments. •Changes in the nature and volume of the portfolio and in the terms of loans and leases. •Changes in the experience, ability, and depth of lending management and other relevant staff. •Changes in the volume and severity of past due loans and leases, the volume of non-accrual loans and leases, and the volume and severity of adversely classified or graded loans and leases. •Changes in the quality of the Bank's credit review system. •Changes in the value of the underlying collateral for collateral-dependent loans and leases. •The existence and effect of any concentrations of credit, and changes in the level of such concentrations. •The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the Bank's existing portfolio. The Company evaluated each qualitative factor as of September 30, 2020, and concluded that a $40.6 million increase to the model results was appropriate for the allowance for credit losses on loans and leases, due to model limitations in the current economic environment. The Company also determined that a $5.0 million increase to the calculated results was appropriate for the RUC related to construction loans. Models were deemed to be under predicting losses, because certain economic variables were lagging indicators and had not yet shown the effects of the current recession, and models were not appropriately capturing elevated risk associated with payment deferral programs offered by the Bank. Loss factors from the models, prepayment speeds, and qualitative factors are input into the Company's CECL accounting application which aggregates the information. The Company then uses two methods to calculate the current expected credit loss: 1) the discounted cash flow ("DCF") method, which is used for all loans except lines of credit and 2) the non-discounted cash flow method which is used for lines of credit due to difficulty of calculating an effective interest rate when lines have yet to be drawn on. The DCF method utilizes the effective interest rate of individual assets to discount the expected credit losses adjusted for prepayments. The difference in the net present value and the amortized cost of the asset will result in the required allowance. The non-discounted cash flow method uses the exposure at default, along with the expected credit losses adjusted for prepayments to calculate the required allowance.

The Bank's Credit Quality Administration is charged with monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank. Reviews of non-performing, past due loans and leases and larger credits, designed to identify potential charges to the allowance for credit losses, and to determine the adequacy of the allowance, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers, the value of the applicable collateral, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions and other factors. Loans and Leases Past Due and Non-Accrual Loans and Leases Typically, loans in a non-accrual status will not have an allowance for credit loss as they will be written down to their net realizable value or charged-off. However, the net realizable value for homogeneous leases and equipment finance agreements is determined by the LGD calculated by the CECL model and therefore leases and equipment finance agreements on non-accrual will have an allowance for credit losses until they become 181 days past due, at which time they are charged-off. The Company recognized no interest income on non-accrual loans and leases during the three and nine months ended September 30, 2020. As of September 30, 2020, loans of approximately $782.3 million are currently deferred under the CARES Act or interagency guidance and are classified as current as their contractual payments have been deferred.

The TDRs were granted in response to borrower financial difficulties, and generally provide for a temporary modification of loan repayment terms. In order for a new TDR loan to be considered for accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow.

There were $132,000 and $9.6 million in financing receivables modified as troubled debt restructurings within the previous 12 months for which there was a payment default during the three and nine months ended September 30, 2020. There were no financing receivables modified as troubled debt restructurings within the previous 12 months for which there was a payment default during the three and nine months ended September 30, 2019. COVID-19 Related Payment Deferral and Forbearance Due to the deterioration of the US economy resulting from the COVID-19 pandemic, the Company has had an increase in loan payment deferral and forbearance requests. Once a deferral or forbearance request is received, a late charge waiver is put in place and payments are suspended for an agreed-upon period. Accrued and unpaid interest during the deferral period will be collected upon the expiration of the deferral or on a regular repayment schedule at the end of the deferral period. For certain loan types, the maturity date may be extended one to six months to allow for full amortization. In accordance with the CARES Act and interagency guidance, these loans are generally classified based on their past due status prior to their deferral period, so they are classified as performing loans that accrue interest. Credit Quality Indicators Management regularly reviews loans and leases in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading. In addition, the board reviews and approves the credit quality indicators each year. The Bank differentiates its lending portfolios into homogeneous and non-homogeneous loans and leases. Homogeneous loans and leases are risk rated on a single risk rating scale based on the past due status of the loan or lease. The Bank's risk rating methodology for its non-homogeneous loans and leases uses a dual risk rating approach to assess the credit risk. This approach uses two scales to provide a comprehensive assessment of credit default risk and recovery risk. The probability of default scale measures a borrower's credit default risk using risk ratings ranging from 1 to 16, where a higher rating represents higher risk. For non-homogeneous loans and leases, PD ratings of 1 through 9 are "pass" grades, while PD ratings of 10 and 11 are "watch" grades. PD ratings of 12-16 correspond to the regulatory-defined categories of special mention (12), substandard (13-14), doubtful (15), and loss (16). The loss given default scale measures the amount of loss that may not be recovered in the event of a default, using six alphabetic ratings from A-F, where a higher rating represents higher risk. The LGD scale quantifies recovery risk associated with an event of default and predicts the amount of loss that would be incurred on a loan or lease if a borrower were to experience a major default and includes variables that may be external to the borrower, such as industry, geographic location, and credit cycle stage. It could also include variables specific to the borrower such as their probability of default and bankruptcies as well as variables specific to the loan or lease, including collateral valuation, covenant structure and debt type. The product of the borrower's PD and a loan or lease LGD is the loan or lease expected loss, expressed as a percentage. This provides a common language of credit risk across different loans. The PD scale estimates the likelihood that a borrower will experience a major default on any of its debt obligations within a specified time period. Examples of major defaults include payments 90 days or more past due, non-accrual classification, bankruptcy filing, or a full or partial charge-off of a loan or lease. As such, the PD scale represents the credit quality indicator for non-homogeneous loans and leases. The credit quality indicator rating categories follow regulatory classification and can be generally described by the following groupings for loans and leases: Pass—A pass loan or lease is a loan or lease with a credit risk level acceptable to the Bank for extending credit and maintaining normal credit monitoring. Watch—A watch loan or lease is considered pass rated but has a heightened level of unacceptable default risk due to an emerging risk element or declining performance trend. Watch ratings are expected to be temporary, with issues resolved or manifested to the extent that a higher or lower risk rating would be appropriate within a short period of time. Special Mention—A special mention loan or lease has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution's credit position at some future date. These borrowers have an elevated probability of default but not to the point of a substandard classification. Substandard—A substandard asset is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Doubtful—Loans or leases classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and values, highly questionable and improbable. Loss—Loans or leases classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted.

Commitments and Contingencies	9 Months Ended
	Sep. 30, 2020
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies    Financial Instruments with Off-Balance-Sheet Risk — The Company's financial statements do not reflect various commitments and contingent liabilities that arise in the normal course of the Bank's business and involve elements of credit, liquidity, and interest rate risk.    The following table presents a summary of the Bank's commitments and contingent liabilities:    (in thousands) September 30, 2020 Commitments to extend credit $ 5,785,909  Forward sales commitments $ 1,029,734  Commitments to originate residential mortgage loans held for sale $ 950,570  Standby letters of credit $ 101,978    The Bank is a party to financial instruments with off-balance-sheet credit risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Those instruments involve elements of credit and interest-rate risk similar to the risk involved in on-balance sheet items. The contract or notional amounts of those instruments reflect the extent of the Bank's involvement in particular classes of financial instruments.    The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, and financial guarantees written, is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.  There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three and nine months ended September 30, 2020 and 2019. At September 30, 2020, approximately $91.5 million of standby letters of credit expire within one year, and $10.5 million expire thereafter. Residential mortgage loans sold into the secondary market are sold with limited recourse against the Company, meaning that the Company may be obligated to repurchase or otherwise reimburse the investor for incurred losses on any loans that suffer an early payment default, are not underwritten in accordance with investor guidelines or are determined to have pre-closing borrower misrepresentations. As of September 30, 2020, the Company had a residential mortgage loan repurchase reserve liability of $1.6 million. For loans sold to GNMA, the Bank has a unilateral right, but not the obligation, to repurchase loans that are past due 90 days or more. As of September 30, 2020, the Bank has recorded a liability for the loans subject to this repurchase right of $20.0 million, and has recorded these loans as part of the loan portfolio as if the Bank had repurchased these loans.   Commitments — In September 2020, the Company and its wholly-owned subsidiary Umpqua Investments, entered into an agreement to sell substantially all of the assets of Umpqua Investments to Steward Partners. Umpqua Investments is included within the Company's Wealth Management segment. The acquisition is expected to close in the first quarter of 2021, subject to customary closing conditions. Legal Proceedings—Umpqua is involved in legal proceedings occurring in the ordinary course of business. Based on information currently available, advice of counsel and available insurance coverage, management believes that the eventual outcome of actions against the Company or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on its consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to results of operations for any particular period. Concentrations of Credit Risk— The Bank grants real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers throughout Oregon, Washington, California, Idaho, and Nevada. In management's judgment, a concentration exists in real estate-related loans, which represented approximately 71% and 76% of the Bank's loan and lease portfolio at September 30, 2020 and December 31, 2019, respectively. The decrease is related to PPP loans which are not real estate secured and will likely be short-term in duration. Commercial real estate concentrations are managed to ensure geographic and business diversity, primarily in our footprint. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general or caused by the COVID-19 pandemic, material increases in interest rates, changes in tax policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary market areas in particular, could have an adverse impact on the repayment of these loans.  Personal and business incomes, proceeds from the sale of real property, or proceeds from refinancing represent the primary sources of repayment for a majority of these loans.    The Bank recognizes the credit risks inherent in dealing with other depository institutions. Accordingly, to prevent excessive exposure to any single correspondent, the Bank has established general standards for selecting correspondent banks as well as internal limits for allowable exposure to any single correspondent. In addition, the Bank has an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

Derivatives	9 Months Ended
	Sep. 30, 2020
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives    The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy.  The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments.  Credit risk associated with forward contracts is limited to the replacement cost of those forward contracts in a gain position.  There were no counterparty default losses on forward contracts in the three and nine months ended September 30, 2020 and 2019.  Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward contracts with broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker/dealer equal to the increase or decrease in the market value of the forward contract. At September 30, 2020, the Bank had commitments to originate mortgage loans held for sale totaling $950.6 million and forward sales commitments of $1.0 billion, which are used to hedge both on-balance sheet and off-balance sheet exposures.    The Bank executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of September 30, 2020, the Bank had 884 interest rate swaps with an aggregate notional amount of $6.2 billion related to this program.  As of December 31, 2019, the Bank had 846 interest rate swaps with an aggregate notional amount of $5.7 billion related to this program. At both September 30, 2020 and December 31, 2019, the termination value of interest rate swaps in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $65,000 and $7.0 million, respectively. The Bank has collateral posting requirements for initial margins with its clearing members and clearing houses and has been required to post collateral against its obligations under these agreements of $103.1 million and $86.2 million as of September 30, 2020 and December 31, 2019, respectively.  The Bank's interest rate swap derivatives are cleared through the Chicago Mercantile Exchange and London Clearing House. These clearing houses characterize the variation margin payments, for derivative contracts that are referred to as settled-to-market, as settlements of the derivative's mark-to-market exposure and not collateral. The Company accounts for the variation margin as an adjustment to cash collateral, as well as a corresponding adjustment to derivative asset and liability. As of September 30, 2020 and December 31, 2019, the variation margin adjustments were negative adjustments of $374.8 million and $144.8 million, respectively.   The Bank incorporates credit valuation adjustments ("CVA") to appropriately reflect nonperformance risk in the fair value measurement of its derivatives. The net CVA reduced the settlement values of the Bank's net derivative assets by $22.5 million and $9.1 million as of September 30, 2020 and December 31, 2019, respectively. Various factors impact changes in the CVA over time, including changes in the credit spreads of the parties to the contracts, as well as changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments. The Bank also executes foreign currency hedges as a service for customers. These foreign currency hedges are then offset with hedges with other third-party banks to limit the Bank's risk exposure. The Bank's derivative assets are included in other assets, while the derivative liabilities are included in other liabilities on the condensed consolidated balance sheet. The following table summarizes the types of derivatives, separately by assets and liabilities, and the fair values of such derivatives as of September 30, 2020 and December 31, 2019:   (in thousands) Asset Derivatives Liability Derivatives Derivatives not designated as hedging instrument September 30, 2020 December 31, 2019 September 30, 2020 December 31, 2019 Interest rate lock commitments $ 28,839  $ 7,056  $ —  $ —  Interest rate forward sales commitments 814  105  2,843  1,351  Interest rate swaps 352,956  142,787  65  7,001  Foreign currency derivatives 562  626  525  456  Total derivative assets and liabilities $ 383,171  $ 150,574  $ 3,433  $ 8,808    The following table summarizes the types of derivatives and the gains (losses) recorded during the three and nine months ended September 30, 2020 and 2019:   (in thousands) Three Months Ended Nine Months Ended Derivatives not designated as hedging instrument September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Interest rate lock commitments $ 3,303  $ 922  $ 21,784  $ 2,313  Interest rate forward sales commitments (11,650) (2,467) (51,952) (11,875) Interest rate swaps 1,765  (2,281) (13,364) (8,712) Foreign currency derivatives 585  527  1,567  1,522  Total derivative losses $ (5,997) $ (3,299) $ (41,965) $ (16,752)   The gains and losses on the Company's mortgage banking derivatives are included in mortgage banking revenue.

Segment Information	9 Months Ended
	Sep. 30, 2020
Segment Reporting [Abstract]
Segment Information	Segment Information    The Company reports four primary segments: Wholesale Bank, Wealth Management, Retail Bank, and Home Lending with the remainder as Corporate and other. The Wholesale Bank segment includes lending, treasury and cash management services and customer risk management products to middle market corporate, commercial and business banking customers and includes the operations of FinPac, a commercial leasing company. The Wealth Management segment consists of the operations of Umpqua Investments, which offers a full range of retail brokerage and investment advisory services and products to its clients who consist primarily of individual investors, and Umpqua Private Bank, which serves high net worth individuals with liquid investable assets and provides customized financial solutions and offerings. The Retail Bank segment includes retail and small business lending and deposit services for customers served through the Bank's store network. The Home Lending segment originates, sells and services residential mortgage loans. The Corporate and other segment includes activities that are not directly attributable to one of the four principal lines of business and includes the operations of the parent company, eliminations and the economic impact of certain assets, capital and support functions not specifically identifiable within the other lines of business. Management monitors the Company's results using an internal performance measurement accounting system, which provides line of business results and key performance measures. The application and development of these management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised retrospectively. In the current period, certain business banking related departments were moved from Retail Bank to Wholesale Bank to realign with Umpqua's strategic goals. The prior periods have been revised accordingly. The provision for income taxes is typically allocated to business segments using a 25% effective tax rate. The residual income tax expense or benefit arising from tax planning strategies or other tax attributes to arrive at the consolidated effective tax rate is retained in Corporate and Other. Summarized financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables: Three Months Ended September 30, 2020 (in thousands) Wholesale Bank Wealth Management Retail Bank Home Lending Corporate & Other (2) Consolidated Net interest income $ 118,913  $ 5,777  $ 57,938  $ 17,937  $ 16,009  $ 216,574  Provision (recapture) for credit losses 5,999  (572) (78) (5,753) 66  (338) Non-interest income 15,298  4,007  18,481  90,593  3,545  131,924  Non-interest expense 60,935  8,050  58,666  49,014  13,542  190,207  Income before income taxes 67,277  2,306  17,831  65,269  5,946  158,629  Provision (benefit) for income taxes (1) 14,317  577  3,795  16,317  (1,248) 33,758  Net income $ 52,960  $ 1,729  $ 14,036  $ 48,952  $ 7,194  $ 124,871  Notable fair value adjustments included in non-interest income: Residential mortgage servicing rights $ —  $ —  $ —  $ (17,122) $ —  $ (17,122) Interest rate swaps 1,765  —  —  —  —  1,765  (1) The Wholesale Bank and Retail Bank do not have the standard tax rate of 25% allocated in 2020 due to the impact of the goodwill impairment on these reporting units.

The following methods were used to estimate the fair value of each class of financial instrument that is carried at fair value in the tables above:    Securities— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.   Loans Held for Sale— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights.   Residential Mortgage Servicing Rights— The fair value of the MSRs is estimated using a discounted cash flow model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants.    Junior Subordinated Debentures— The fair value of junior subordinated debentures is estimated using an income approach valuation technique.  The significant inputs utilized in the estimation of fair value of these instruments are the credit risk adjusted spread and three-month LIBOR. The credit risk adjusted spread represents the nonperformance risk of the liability, contemplating the inherent risk of the obligation. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants.  Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, the Company has classified this as a Level 3 fair value measurement.     Derivative Instruments— The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate.  The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2020, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.      Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3)    The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at September 30, 2020:  Financial Instrument Fair Value Valuation Technique Unobservable Input Range of Inputs Weighted Average Residential mortgage servicing rights $ 93,248  Discounted cash flow         Constant prepayment rate 9.68 - 79.94% 18.10%     Discount rate 9.50 - 12.50% 9.74% Interest rate lock commitments $ 28,839  Internal pricing model Pull-through rate 49.79 - 100.00% 84.78% Junior subordinated debentures $ 247,045  Discounted cash flow         Credit spread 4.36 - 5.78% 4.94% Generally, increases in the constant prepayment rate or the discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in a decrease in fair value. Conversely, decreases in the constant prepayment rate or the discount rate will result in an increase in fair value. An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate will result in a decrease in the fair value measurement. Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, which is an inactive market. Management attributes the change in fair value of the junior subordinated debentures during the period to market changes in the nonperformance expectations and pricing of this type of debt. The widening of the credit risk adjusted spread above the Company's contractual spreads has primarily contributed to the decrease in the estimated fair value.  Future contractions in the instrument-specific credit risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of September 30, 2020, or the passage of time, will result in an increase in the estimated fair value.  Generally, an increase in the credit spread will result in a decrease in the estimated fair value. Conversely, a decrease in the credit spread will result in an increase in the estimated fair value. The following tables provide a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the three and nine months ended September 30, 2020 and 2019:  Three Months Ended Three Months Ended September 30, 2020 September 30, 2019 (in thousands) Residential mortgage servicing rights Interest rate lock commitments, net Junior subordinated debentures, at fair value Residential mortgage servicing rights Interest rate lock commitments, net Junior subordinated debentures, at fair value Beginning balance $ 96,356  $ 25,537  $ 232,936  $ 139,780  $ 8,149  $ 277,028  Transfer out of level 3 —  —  —  (36,191) —  —  Change included in earnings (17,122) 3,723  2,536  4,210  1,456  4,495  Change in fair values included in comprehensive income/loss —  —  14,555  —  —  (8,450) Purchases and issuances 14,014  55,854  —  7,393  9,027  —  Sales and settlements —  (56,275) (2,982) —  (9,562) (5,275) Ending balance $ 93,248  $ 28,839  $ 247,045  $ 115,192  $ 9,070  $ 267,798  Change in unrealized gains or losses for the period included in earnings for assets held at end of period $ (12,244) $ 28,839  $ 2,536  $ 11,045  $ 9,070  $ 4,495  Change in unrealized gains or losses for the period included in other comprehensive income for assets held at end of period $ —  $ —  $ 14,555  $ —  $ —  $ (8,450) Nine Months Ended Nine Months Ended September 30, 2020 September 30, 2019 Residential mortgage servicing rights Interest rate lock commitments, net Junior subordinated debentures, at fair value Residential mortgage servicing rights Interest rate lock commitments, net Junior subordinated debentures, at fair value Beginning Balance $ 115,010  $ 7,056  $ 274,812  $ 169,025  $ 6,757  $ 300,870  Transfer out of level 3 —  —  —  (36,191) —  —  Change included in earnings (59,246) 10,946  9,509  (34,414) 4,455  13,952  Change in fair values included in comprehensive income/loss —  —  (26,857) —  —  (32,254) Purchases and issuances 37,484  130,862  —  16,772  21,318  —  Sales and settlements —  (120,025) (10,419) —  (23,460) (14,770) Ending Balance $ 93,248  $ 28,839  $ 247,045  $ 115,192  $ 9,070  $ 267,798  Change in unrealized gains or losses for the period included in earnings for assets held at end of period $ (43,997) $ 28,839  $ 9,509  $ (14,243) $ 9,070  $ 13,952  Change in unrealized gains or losses for the period included in other comprehensive income for assets held at end of period $ —  $ —  $ (26,857) $ —  $ —  $ (32,254) Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments carried at fair value are recorded in residential mortgage banking revenue within non-interest income. The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities.  The change in fair value of junior subordinated debentures is attributable to the change in the instrument specific credit risk; accordingly, the unrealized losses on fair value of junior subordinated debentures of $14.6 million and unrealized gains of $26.9 million, respectively, for the three and nine months ended September 30, 2020, are recorded net of tax as an other comprehensive loss of $10.8 million and other comprehensive income of $20.0 million, respectively. Comparatively, unrealized gains of $8.5 million and $32.3 million, respectively, were recorded net of tax as an other comprehensive income of $6.3 million and $24.0 million for the three and nine months ended September 30, 2019. The gain recorded for the nine months ended September 30, 2020 is due mostly to an overall increase in the discount rates due to an increase in the credit spread, in addition to the implied forward curve shifting lower. The loss recorded for the three months ended September 30, 2020 was due primarily to a decrease in the credit spread which resulted in a lower discount rate and an increase in the forward curve partially offset by an increase in the spot curve. From time to time, certain assets are measured at fair value on a nonrecurring basis.  These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral dependent loans.    Fair Value of Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis    The following tables present information about the Company's assets and liabilities measured at fair value on a nonrecurring basis for which a nonrecurring change in fair value has been recorded during the reporting period.  The amounts disclosed below represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported upon.  September 30, 2020  (in thousands) Total Level 1 Level 2 Level 3 Loans and leases $ 8,231  $ —  $ —  $ 8,231  Goodwill (Wholesale Bank and Retail Bank) —  —  —  —  Other real estate owned 2,046  —  —  2,046  Total assets measured at fair value on a nonrecurring basis $ 10,277  $ —  $ —  $ 10,277  December 31, 2019  (in thousands)  Total Level 1 Level 2 Level 3 Loans and leases $ 18,134  $ —  $ —  $ 18,134  Other real estate owned 2,079  —  —  2,079  Total assets measured at fair value on a nonrecurring basis $ 20,213  $ —  $ —  $ 20,213  The following table presents the losses resulting from nonrecurring fair value adjustments for the three and nine months ended September 30, 2020 and 2019:   Three Months Ended Nine Months Ended   (in thousands)  September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Loans and leases $ 14,797  $ 20,435  $ 53,336  $ 51,212  Goodwill impairment (Wholesale Bank and Retail Bank) —  —  1,784,936  —  Other real estate owned 352  279  499  3,013  Total loss from nonrecurring measurements $ 15,149  $ 20,714  $ 1,838,771  $ 54,225  Goodwill was evaluated for impairment as of March 31, 2020, for the Retail Bank and Wholesale Bank reporting units. Refer to Note 11 - Goodwill, for discussion of the Company's goodwill impairment analysis. The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis, excluding goodwill. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information for loans and leases and other real estate owned. The loans and leases amounts above represent collateral dependent loans and leases that have been adjusted to fair value.  When a loan or non-homogeneous lease is identified as collateral dependent, the Bank measures the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan or lease, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little to no value.  When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is determined that the collateral has little to no value. If it is determined that the value of the collateral dependent loan or lease is less than its recorded investment, the Bank recognizes this impairment and adjusts the carrying value of the loan or lease to fair value, less costs to sell, through the allowance for credit losses. The loss represents charge-offs on collateral dependent loans and leases for fair value adjustments based on the fair value of collateral.   The other real estate owned amount above represents impaired real estate that has been adjusted to fair value.  Other real estate owned represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate.  Fair Value Option The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 (in thousands) Fair Value  Aggregate Unpaid Principal Balance Fair Value Less Aggregate Unpaid Principal Balance Fair Value Aggregate Unpaid Principal Balance Fair Value Less Aggregate Unpaid Principal Balance   Loans held for sale $ 677,773  $ 644,507  $ 33,266  $ 513,431  $ 496,683  $ 16,748  Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue. For the three and nine months ended September 30, 2020, the Company recorded a net increase in fair value of $2.2 million and $16.5 million, respectively. For the three and nine months ended September 30, 2019, the Company recorded a net decrease in fair value of $1.9 million and an increase of $5.8 million, respectively. The Company selected the fair value measurement option for certain junior subordinated debentures. The remaining junior subordinated debentures were acquired through previous business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost. Accounting for the selected junior subordinated debentures at fair value enables the Company to more closely align financial performance with the economic value of those liabilities. Additionally, it improves the ability to manage the market and interest rate risks associated with the junior subordinated debentures. The junior subordinated debentures measured at fair value and amortized cost are presented as separate line items on the balance sheet. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants under current market conditions as of the measurement date. Due to inactivity in the junior subordinated debenture market and the lack of observable quotes of the Company's, or similar, junior subordinated debenture liabilities or the related trust preferred securities when traded as assets, the Company utilizes an income approach valuation technique to determine the fair value of these liabilities using estimation of market discount rate assumptions. The Company monitors activity in the trust preferred and related markets, to the extent available, evaluates changes related to the current and anticipated future interest rate environment, and considers entity-specific creditworthiness, to validate the reasonableness of the credit risk adjusted spread and effective yield utilized in the discounted cash flow model. The Company also considers changes in the interest rate environment in the valuation, specifically the absolute level and the shape of the slope of the forward swap curve.

Goodwill	9 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill At September 30, 2020, goodwill totaled $2.7 million, after a goodwill impairment of $1.8 billion was recorded as of March 31, 2020. Goodwill was $1.8 billion at December 31, 2019. Goodwill is required to be allocated to reporting units, which the Company has determined to be the same as its operating segments. The following table summarizes the change in the Company's goodwill for the nine months ended September 30, 2020: Goodwill (in thousands) Gross Accumulated Impairment Total Balance, December 31, 2019 $ 1,900,727  $ (113,076) $ 1,787,651  Goodwill impairment —  (1,784,936) (1,784,936) Balance, September 30, 2020 $ 1,900,727  $ (1,898,012) $ 2,715  As of September 30, 2020 and December 31, 2019, goodwill was allocated to the reporting units as follows: Goodwill (in thousands) Wholesale Bank Wealth Management Retail Bank Total Allocated goodwill, December 31, 2019 $ 1,033,744  $ 2,715  $ 751,192  $ 1,787,651  Goodwill impairment (1,033,744) —  (751,192) (1,784,936) Allocated goodwill, September 30, 2020 $ —  $ 2,715  $ —  $ 2,715  The Company updated its goodwill assessment for the Wholesale Bank and Retail Bank reporting units as of March 31, 2020, due to events and circumstances indicating potential impairment. Impairment of goodwill is the condition that exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value. A goodwill impairment is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. The Company assessed qualitative factors that indicated that it was more likely than not that goodwill was impaired as of March 31, 2020. Based on that assessment, the Company determined that for the Wholesale Bank and Retail Bank reporting units, the qualitative analysis determined that there were negative indicators that would require a quantitative assessment of goodwill due to the decline in the current economic environment, specifically interest rates and the Company's stock price, as well as decreasing cash flow projections for these reporting units based on the low interest rate environment and potentially higher credit losses. The Company performed a quantitative analysis of the Wholesale Bank and Retail Bank reporting units, by comparing the fair value of these reporting units with their carrying amount. The Company estimated the fair value of its Wholesale Bank and Retail Bank reporting units using an income approach to estimate the fair value of both reporting units. The income approach estimates the fair value of the reporting units by discounting management's projections of the reporting units' cash flows, including a terminal value to estimate the fair value of cash flows beyond the final year of projected results, discounted using an estimated cost of capital discount rate. The Company also considered the market and cost approaches when determining the fair value of the reporting units. The projected cash flows used to estimate fair value of the reporting units was lower than previous projections due to declining interest rate forecasts for a prolonged low-interest rate environment, due to the significant impact of the Federal Reserve's rate cuts and the impact of the COVID-19 pandemic on the economy. Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates, and market factors. Estimating the fair value of individual reporting units requires management to make assumptions and estimates regarding the Company's future plans, as well as industry, economic, and regulatory conditions. These assumptions and estimates include estimated future annual net cash flows, income tax rates, discount rates, growth rates, and other market factors. Upon completing the quantitative impairment analysis as of March 31, 2020, the Company recorded a goodwill impairment of $1.8 billion, which represented the entire amount of goodwill allocated to the Wholesale Bank and Retail Bank reporting units. The remaining goodwill of $2.7 million after the impairment relates to the Wealth Management reporting unit. As of September 30, 2020, the Company updated its goodwill impairment analysis for the Wealth Management reporting unit by assessing qualitative factors to determine whether the existence of events and circumstances indicated that it is more likely than not that goodwill is impaired. Based upon that assessment, the Company determined that there were no additional factors indicating impairment and no further testing was determined to be necessary as of September 30, 2020.

Income Taxes	9 Months Ended
	Sep. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as in the majority of states and in Canada. As of September 30, 2020, the Company has a net deferred tax liability of $13.2 million, which includes $2.0 million of state net operating loss ("NOL") carry-forwards, expiring in tax years 2029-2031. The Company believes that it is more likely than not that the benefit from only certain state NOL carry-forwards will not be realized and therefore has provided a valuation allowance of $1.1 million against the deferred tax assets relating to these NOL carry-forwards. The Company had gross unrecognized tax benefits of $4.3 million as of September 30, 2020. If recognized, the unrecognized tax benefit would reduce the 2020 annual effective tax rate by 0.27%. The Company's consolidated effective tax rate as a percentage of pre-tax income (loss) for the three and nine months ended September 30, 2020 was 21.3% and (4.4)%, respectively, as compared to 23.6% and 24.5% for the three and nine months ended September 30, 2019. The effective tax rate decreased from the prior year primarily due to the impairment of non-deductible goodwill during the nine months ended September 30, 2020. Additionally, the effective tax rates differed from the statutory rate principally because of state taxes, non-taxable income arising from bank owned life insurance, income on tax-exempt investment securities, non-deductible FDIC premiums and tax credits arising from low-income housing investments.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses Policy- The Bank has established an Allowance for Credit Loss Committee, which is responsible for, among other things, regularly reviewing the ACL methodology, including allowance levels and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The Bank's Audit and Compliance Committee provides board oversight of the ACL process and reviews and approves the ACL methodology on a quarterly basis. CECL is not prescriptive in the methodology used to determine the expected credit loss estimate. Instead, management has flexibility in selecting the methodology. The expected credit losses must be estimated over a financial asset's contractual term, adjusted for prepayments utilizing quantitative and qualitative factors. There are also specific considerations for PCD, Troubled Debt Restructured ("TDR"), and Collateral Dependent Loans ("CDL"). The estimate of current expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms, and differences in economic conditions – both current conditions and reasonable and supportable forecasts. When the Company is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it has estimated expected credit losses for the remaining life using an approach that reverts to historical credit loss information for the longer-term portion of the asset's life. The Company utilizes complex models to obtain reasonable and supportable forecasts; most of the models calculate two predictive metrics: the probability of default ("PD") and loss given default ("LGD"). The PD measures the probability that a loan will default within a given time horizon and primarily measures the adequacy of the debtor's cash flow as the primary source of repayment of the loan or lease. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary source of repayment related to the collateral. The combination of the current expected credit loss, PCD, CDL, TDR, and the RUC components represent the ACL. Management believes that the ACL was adequate as of September 30, 2020. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could possibly result in additional charges to the provision for credit losses.
Acquired Loans and Leases	Acquired Loans and Leases- Loans and leases purchased without more-than-insignificant credit deterioration, are recorded at their fair value at the acquisition date. However, loans and leases purchased with more-than-insignificant credit deterioration will be recorded with their applicable allowance for credit loss to determine the amortized cost basis.
Originated Loans and Leases	Originated Loans and Leases- Loans are stated at the amount of unpaid principal, net of unearned income and any deferred fees or costs. All discounts and premiums are recognized over the contractual life of the loan as yield adjustments. Leases are recorded at the amount of minimum future lease payments receivable and estimated residual value of the leased equipment, net of unearned income and any deferred fees. Initial direct costs related to lease originations are deferred as part of the investment in direct financing leases and amortized over their term using the effective interest method. Unearned lease income is amortized over the term using the effective interest method.
Income Recognition on Non-Accrual Loans	Income Recognition on Non-Accrual Loans- Loans are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a commercial or commercial real estate loan is past due beyond its maturity or principal or interest payment due date by 90 days or more, unless such loans are well-secured and in the process of collection. Loans that are less than 90 days past due may also be classified as non-accrual if repayment in full of principal and/or interest is in doubt.Generally, when a loan is classified as non-accrual, all uncollected accrued interest is reversed from interest income and the accrual of interest income is terminated. In addition, any cash payments subsequently received are applied as a reduction of principal outstanding. In cases where the future collectability of the principal balance in full is expected, interest income may be recognized on a cash basis. A loan may be restored to accrual status when the borrower's financial condition improves so that full collection of future contractual payments is considered likely. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will typically not occur until the borrower demonstrates repayment ability over a period of not less than six months.
Collateral Dependent Loans and Troubled Debt Restructurings	Collateral Dependent Loans and Troubled Debt Restructurings- A loan or lease is considered collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. The Company's classification of CDLs includes: non-homogeneous non-accrual loans and leases; non-homogeneous loans determined by individual credit review; homogeneous non-accrual leases and equipment finance agreements; and homogeneous real estate secured loans that have been charged down to net realizable value or the government guaranteed balance. Except for homogeneous leases and equipment finance agreements, the expected credit losses for CDLs will be measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. The Company may also use the loan's observable market price, if available. If the value of the CDL is determined to be less than the recorded amount of the loan, a charge-off will be taken. To determine the expected credit loss for homogeneous leases or equipment finance agreements, the LGD calculated by the CECL model will be utilized. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is fully charged-off. Loans are reported as TDR loans when, due to borrower financial difficulties, the Bank grants a concession it would not otherwise be willing to offer for a loan. Once a loan has been classified as a TDR, it continues in the classification until it has paid in full or it has demonstrated six months of payment performance and was determined to have been modified at a market rate terms. TDRs, including reasonably expected TDRs, are individually recognized and measured for expected credit loss in one of two ways: when a TDR meets the definition of a CDL, it is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable; otherwise, a discounted cash flow analysis is utilized to measure the expected credit loss for a TDR. The expected cash flow for a TDR is discounted based on the pre-modification rate and the expected remaining life. In March 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was passed, which, among other things, provided relief for Banks related to loan modifications for accounting purposes. Specifically, section 4013 of the CARES Act gives entities temporary relief from the accounting and disclosure requirements for TDRs. In addition to the CARES Act, bank regulatory agencies issued interagency guidance indicating that a lender could conclude that the modifications under section 4013 of the CARES Act or the interagency guidance are not a TDR if certain criteria are met. The guidance also provides that loans generally will not be adversely classified if the short-term modification is related to COVID-19 relief programs. The Company has followed the guidance under the CARES Act and the interagency guidance related to these loan modifications. Loans modified under section 4013 of the CARES Act or the interagency guidance generally maintain their pre-COVID-19 delinquency status and are classified as performing loans. If it is deemed the modification is not short-term, not COVID-19 related or the customer does not meet the criteria under the guidance to be scoped out of troubled debt restructuring classification, the Company evaluates the loan modifications under its existing framework which requires modifications that result in a concession without appropriate compensation to a borrower experiencing financial difficulty to be accounted for as a TDR.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments- A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb expected losses associated with the Bank's commitment to lend funds under existing agreements, such as letters or lines of credit. The RUC calculation utilizes the allowance for credit loss on loans and leases rates, probability of default risk ratings, and utilization rates based on the economic expectations over the contractual life of the commitment. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and adjustments are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on loans and leases. Provisions for unfunded commitment losses are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets.
Investment Securities Available for Sale	Investment Securities Available for Sale- Debt securities are classified as available for sale if the Company intends and has the ability to hold those securities for an indefinite period of time, but not necessarily to maturity. Any decision to sell a debt security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned. Securities available for sale are carried at fair value. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Unrealized holding gains or losses are included in other comprehensive income ("OCI") as a separate component of shareholders' equity, net of tax. When the fair value of an available-for-sale debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. Decreases in fair value attributable to credit loss would be recorded directly to earnings with a corresponding allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves the allowance would be reversed up to a maximum of the previously recorded credit losses. If the Company intends to sell an impaired available-for-sale debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment would be immediately recognized in earnings with no corresponding allowance for credit losses.
Recent Accounting Pronouncements	In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. This ASU was issued to improve the effectiveness of disclosures surrounding fair value measurements. The ASU removes numerous disclosures from Topic 820 including: transfers between level 1 and 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation process for level 3 fair value measurements. The ASU also modified and added disclosure requirements in regards to changes in unrealized gains and losses included in other comprehensive income, as well as the range and weighted average of unobservable inputs for level 3 fair value measurements. The Company adopted this ASU as of January 1, 2020, on a retrospective basis except certain provisions of the guidance which are only required to be applied on a prospective basis. Recent accounting pronouncements  In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. The expedients are in effect from March 12, 2020, through December 31, 2022. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements.
Derivatives	Derivatives  The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy.
