The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on March 4, 2020.

SIGNIFICANT RISKS AND UNCERTAINTIES

The Company’s condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that there was no material adverse impact on the Company’s first half 2020 results of operations.

The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company's customers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, delays in obtaining signed customer contracts for awarded projects, supply chain disruptions and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, the extent to which the COVID-19 pandemic may impact the Company's financial condition, liquidity, or results of operations is uncertain.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. The Company estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 , an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback additionally provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting policies of the Company are set forth in Note 2 to the consolidated financial statements contained in the Company’s 2019 annual report on Form 10-K. The Company includes herein certain updates to those policies.

Accounts Receivable and allowance for Credit Losses

Accounts receivable are stated at the amount management expects to collect from outstanding balances. Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13) prospectively. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The amendment requires entities

(in thousands, except per share amounts)

to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. The Company performed an assessment of its allowance for credit losses based upon historical experience, management’s evaluation of outstanding accounts receivable, consideration of its customers’ financial condition and current macroeconomic and market conditions and determined that no adjustment was required to retained earnings upon adoption.

The Company’s methodology to estimate the allowance for credit losses includes quarterly assessments of historical bad debt write off experience, current economic and market conditions, management’s evaluation of outstanding accounts receivable, and the Company’s forecasts. Due to the short-term nature of its receivables, the estimate of credit losses is primarily based on aged accounts receivable balances and the financial condition of customers. In addition, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Bad debts are written off against the allowance when identified. As part of its assessment, the Company also considered the current and expected future economic and market conditions due to the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted as of June 30, 2020.

Changes in the allowance for credit losses for the six months ended June 30, 2020 and 2019 are as follows:


	June 30, 2020		June 30, 2019
Allowance for credit loss, beginning of period	$	2,260	$	2,765
Charges (recoveries) to costs and expenses, net	(80)		124
Account write-offs and other	(192)		(46)
Allowance for credit loss, end of period	$	1,988	$	2,843

	June 30, 2019		December 31, 2018
Accounts receivable, net	$	109,332	$	85,985
Accounts receivable retainage, net	15,383		13,516
Contract Assets:
Costs and estimated earnings in excess of billings	120,686		86,842
Contract Liabilities:
Billings in excess of cost and estimated earnings	30,209		30,706

Accounts receivable retainage represents amounts due from customers, but where payments are withheld contractually until certain construction milestones are met. Amounts retained typically range from 5% to 10% of the total invoice. The Company classifies as a current asset those retainages that are expected to be billed in the next twelve months. Unbilled revenue, presented as costs and estimated earnings in excess of billings, represent amounts earned and billable that were not invoiced at the end of the fiscal period.

Contract assets represent the Company’s rights to consideration in exchange for services transferred to a customer that have not been billed as of the reporting date. The Company’s rights to consideration are generally unconditional at the time its performance obligations are satisfied.

At the inception of a contract, the Company expects the period between when it satisfies its performance obligations, and when the customer pays for the services, will be one year or less. As such, the Company has elected to apply the practical expedient which allows the Company to not adjust the promised amount of consideration for the effects of a significant financing component, when a financing component is present.

When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from billings in excess of costs incurred and advanced payments received on project contracts. As of June 30, 2020 and December 31, 2019, the Company classified $5,035 and $5,560, respectively, as a non-current liability, included in other liabilities on the condensed consolidated balance sheets, for those performance obligations expected to be completed beyond the next twelve months.

The decrease in contract assets for the six months ended June 30, 2020 was primarily due to billings of $302,457, offset in part by revenue recognized of approximately $287,087. The increase in contract liabilities was primarily driven by the receipt of advance payment from customers, and related billings, exceeding reductions from recognition of revenue as performance obligations were satisfied. For the six months ended June 30, 2020, the Company recognized revenue of $33,851 that was previously included in the beginning balance of contract liabilities and billed customers $33,276. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.

The increase in contract assets for the six months ended June 30, 2019 was primarily due to revenue recognized of $220,062, offset in part by billings of approximately $201,908. The decrease in contract liabilities was primarily driven by recognition of revenue as performance obligations were satisfied exceeding increases from the receipt of advance payment from customers, and related billings. For the six months ended June 30, 2019, the Company recognized revenue of $38,854 that was previously included in the beginning balance of contract liabilities, and billed customers $35,172. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.

Contracts are often modified for a change in scope or other requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from the existing performance obligations. The effect of a contract modification on the transaction price, and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase or decrease) on a cumulative catchup basis.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Performance obligations are satisfied at a point in time or over time and are supported by contracts with customers. For most of the

Table of Contents

AMERESCO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)

(in thousands, except per share amounts)

Company’s contracts, there are multiple promises of goods or services. Typically, the Company provides a significant service of integrating a complex set of tasks and components such as design, engineering, construction management, and equipment procurement for a project contract. The bundle of goods and services are provided to deliver one output for which the customer has contracted. In these cases, the Company considers the bundle of goods and services to be a single performance obligation. The Company may also promise to provide distinct goods or services within a contract, such as a project contract for installation of energy conservation measures and post-installation O&M services. In these cases the Company separates the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation.

Backlog - The Company’s remaining performance obligations (hereafter referred to as “backlog”) represent the unrecognized revenue value of the Company’s contract commitments. The Company’s backlog may vary significantly each reporting period based on the timing of major new contract commitments and the backlog may fluctuate with currency movements. In addition, our customers have the right, under some circumstances, to terminate contracts or defer the timing of the Company’s services and their payments to the Company. At June 30, 2020, the Company had backlog of approximately $2,151,185. Approximately 27% of our June 30, 2020 backlog is anticipated to be recognized as revenue in the next twelve months and the remaining, thereafter.

The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

Contract Acquisition Costs

The Company accounts for certain acquisition costs over the life of the contract, consisting primarily of commissions when paid. Commission costs are incurred commencing at contract signing. Commission costs are allocated across all performance obligations and deferred and amortized over the contract term on a progress toward completion basis.

As of June 30, 2020 and December 31, 2019, included in other assets in the accompanying condensed consolidated balance sheets, were $1,735 and $1,735, respectively, of capitalized commission costs related to contracts that were not completed. For contracts that have a duration of less than one year, the Company follows a practical expedient and expenses these costs when incurred. During the three and six months ended June 30, 2020 and 2019, the amortization of commission costs related to contracts was not material and were included in the accompanying condensed consolidated statements of income.

The Company capitalizes costs incurred related to the development of projects prior to contract signing as it is partial fulfillment of its performance obligations. Capitalized project development costs include only those costs incurred in connection with the development of energy projects, primarily direct labor, interest costs, outside contractor services, consulting fees, legal fees and travel, if incurred after a point in time where the realization of related revenue becomes probable. Project development costs incurred prior to the probable realization of revenue are expensed as incurred. The Company classifies as a current asset those project development efforts that are expected to proceed to construction activity in the twelve months that follow. The Company periodically reviews these balances and writes off any amounts where the realization of the related revenue is no longer probable. Project development costs of $550 and $1,080 were included in other long-term assets as of June 30, 2020 and December 31, 2019, respectively. During the three months ended June 30, 2020 and 2019, $4,258 and $8,256, respectively, of project development costs were recognized in the condensed consolidated statements of income on projects that converted to customer contracts. During the six months ended June 30, 2020 and 2019, $5,865 and $11,033, respectively, of project development costs were recognized in the condensed consolidated statements of income on projects that converted to customer contracts.

No impairment charges in connection with the Company’s commission costs or project development costs were recorded during the six months ended June 30, 2020 and 2019.

4. BUSINESS ACQUISITIONS AND RELATED TRANSACTIONS

The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, Business Combinations. The purchase price for each has been allocated to the net assets based on their estimated fair values at the date of

Table of Contents

AMERESCO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)

(in thousands, except per share amounts)

each acquisition as set forth in the table below. The excess purchase price over the estimated fair value of the net assets, which are calculated using level 3 inputs per the fair value hierarchy as defined in Note 10, acquired has been recorded as goodwill. Intangible assets, if identified, have been recorded and are being amortized over periods ranging from one to fifteen years. See Note 5 for additional information.

During the three and six months ended June 30, 2020, the Company did not complete any acquisitions.

The results of the acquired assets since the dates of the acquisitions have been included in the Company’s operations as presented in the accompanying condensed consolidated statements of income, condensed consolidated statements of comprehensive income and condensed consolidated statements of cash flows.

The changes in the carrying value of goodwill attributable to each reportable segment are as follows:

The Company performs its annual goodwill impairment testing in the fourth quarter of each year, or more frequently if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. During the Company’s annual goodwill impairment testing in 2019, all reporting units had fair values that exceeded their carrying values by at least 15%. If the Company believes that one or more indicators of impairment have occurred, then the Company will perform an impairment test. The Company has the option to perform a qualitative assessment (commonly referred to as "step zero" test) to determine whether further quantitative analysis for impairment of goodwill and indefinite-lived intangible assets is necessary. The qualitative assessment includes a review of macroeconomic conditions, industry and market considerations, internal cost factors, and the Company’s own overall financial and share price performance, among other factors. If, after assessing the totality of events or circumstances the Company determines that it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the Company does not need to perform a quantitative analysis. Upon assessment, the Company concluded it was not more likely than not that the fair value of the reporting units were less than the carrying value of the reporting units as of June 30, 2020. The Company will monitor future results and will perform a test if indicators trigger an impairment review. At this time, the Company has not deemed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business to be a triggering event for impairment purposes.

Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. The Company annually assesses whether a change in the life over which the Company’s assets are amortized is necessary, or more frequently if events or circumstances warrant.

Acquired intangible assets other than goodwill that are subject to amortization include customer contracts, customer relationships, non-compete agreements, technology and trade names. Customer contracts are amortized ratably over the period of the acquired customer contracts ranging in periods from approximately one to five years. All other acquired intangible assets are amortized over periods ranging from approximately four to fifteen years, as determined by the nature of the respective intangible asset. The Company did not complete any acquisitions or acquire any intangible assets during the six months ended June 30, 2020.

The Company evaluates long-lived assets for impairment as events or changes in circumstances indicate the carrying value of these assets may not be fully recoverable. Examples of such triggering events applicable to our assets include a significant decrease in the market price of a long-lived asset or asset group or a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group. The Company performs its annual long-lived assets impairment testing in the fourth quarter of each year. In addition to the annual impairment test, the Company regularly assesses whether a triggering event has occurred which would require interim impairment testing. The Company assessed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business, and concluded that it was not a triggering event for impairment purposes and there was no indication of impairment of long-lived assets for the six months ended June 30, 2020.

The Company capitalizes interest costs relating to construction financing during the period of construction. Capitalized interest is included in energy assets, net in the Company’s condensed consolidated balance sheets. Capitalized interest is amortized to cost of revenues in the Company’s condensed consolidated statements of income on a straight line basis over the useful life of the associated energy asset. The Company capitalized $912 and $790 of interest during the three months ended June 30, 2020 and 2019, respectively. The Company had $1,774 and $1,578 of interest capitalized for the six months ended June 30, 2020 and 2019, respectively.

As of June 30, 2020 and December 31, 2019, there are three ESPC asset projects which are included within energy assets, net on the Company’s condensed consolidated balance sheets. The Company controls and operates the assets as well as obtains financing during the construction period of the assets. As the Company has an obligation to the customer for performance of the asset, the Company records a liability associated with these energy assets, although, the customer is responsible for payments to the lender based on the energy asset’s production. As of June 30, 2020 and December 31, 2019, the liabilities recognized in association with these assets were $11,125 and $10,243, respectively, of which $221 and $827, respectively, has been classified as the current portion and is included in accrued expenses and other current liabilities. The remainder is included in other liabilities in the accompanying condensed consolidated balance sheets.

During the three months ended June 30, 2020, the Company acquired one energy project, which did not constitute a business in accordance with ASC 805-50, Business Combinations. The Company acquired the energy project in exchange for total purchase price of $1,251, which included cash of $1,031 paid by the Company, issuance of a promissory note payable to the sellers of $204, detailed further in Note 16, and $16 of rollover equity in connection with shares of one of the Company’s subsidiaries issued to the sellers. As of June 30, 2020, the Company has remaining deferred purchase price consideration on previously closed projects of $1,446 that will be paid upon final completion of the respective projects and throughout 2020. The Company has a definitive agreement from prior periods, which has recently been amended, to purchase eight additional solar projects from developers for a total purchase price of $10,242, of which the Company has not made any payments to the developers for those projects.

As of June 30, 2020, the Company had $1,500 in asset retirement obligations (“AROs”) assets recorded in project assets, net of accumulated depreciation, and $1,597 in ARO liabilities recorded in accrued expenses and other current liabilities and other liabilities. During the three months and six months ended June 30, 2020, the Company recorded $19 and $38, respectively, of depreciation expense related to the ARO assets. During the three months and six months ended June 30, 2020, the Company recorded $22 and $43, respectively, in accretion expense to the ARO liabilities, which is reflected in the accretion

(in thousands, except per share amounts)

of ARO and contingent consideration on the condensed consolidated statements of cash flows. The Company’s current ARO liabilities relate to the removal of equipment and pipelines at certain renewable gas projects and obligations related to the decommissioning of certain solar facilities and wind turbines.

7. INCOME TAXES

The Company recorded a provision for income taxes of $0 and $804 for the three months ended June 30, 2020 and 2019, respectively. The Company recorded a benefit for income taxes of $2,503 and provision for income tax of $1,061 for the six months ended June 30, 2020 and 2019, respectively.The estimated effective annualized tax rate impacted by the period discrete items is (0.0%) of benefit for the three months ended June 30, 2020, compared to a 8.6% of estimated effective annualized tax rate for the three months ended June 30, 2019. The estimated effective annualized tax rate impacted by the period discrete items is (19.3)% of benefit for the six months ended June 30, 2020, compared to a 8.5% of estimated effective annualized tax rate for the six months ended June 30, 2019.

The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or are forecasted to be placed into service during 2020. Tax deductions related to Section 179D deduction, tax basis adjustments on certain partnership flip transactions and tax rate benefits associated with net operating loss carryback made possible by the passing of the COVID-19 CARES Act on March 27, 2020. The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2019 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or were forecasted to be placed into service during 2019.

The investment tax credits and production tax credits to which the Company may be entitled fluctuate from year to year based on the cost of the renewable energy plants the Company places or expects to place in service and production levels at company owned facilities in that year. As part of the Tax Extender and Disaster Relief Act of 2019, signed into law December 20, 2019, Section 179D was extended through December 31, 2020.

A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows:


	Gross Unrecognized Tax Benefits
Balance, December 31, 2019	$	400
Additions for prior year tax positions	—
Settlements with tax authorities	—
Reductions of prior year tax positions	—
Balance, June 30, 2020	$	400

At June 30, 2020 and December 31, 2019, the Company had approximately $400 of total gross unrecognized tax benefits. At June 30, 2020 and December 31, 2019, the Company had approximately $80 of total gross unrecognized tax benefits (both net of the federal benefit on state amounts) representing the amount of unrecognized tax benefits that, if recognized, would favorably affect the effective income tax rate in any future periods.

The Company has presented all deferred tax assets and liabilities as noncurrent, net liabilities on its condensed consolidated balance sheets as of June 30, 2020, and December 31, 2019.

8. LEASES

On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did not reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company has also elected the practical expedient to not separate lease components and non-lease components and will account for the leases as a single lease component for all classes of leases.

As a result of the adoption of ASC 842, the Company recognized an increase in lease right-of-use (“ROU”) assets of $31,639, current portions of operating lease ROU liabilities of $5,084 and an increase to long-term portions of operating lease liabilities of $28,480. There was no net impact to the condensed consolidated statements of income or retained earnings for the adoption of ASC 842. No impairment was recognized on the ROU asset upon adoption. These adjustments are detailed as follows:


	As of January 1, 2019
	As Reported		842 Adjustment		Adjusted Balances

The Company enters into a variety of operating lease agreements through the normal course of its business including certain administrative offices. The leases are long-term, non-concealable real estate lease agreements, expiring at various dates through fiscal 2028. The agreements generally provide for fixed minimum rental payments and the payment of utilities, real estate taxes, insurance and repairs. The Company also leases certain land parcels related to our energy projects, expiring at various dates through fiscal 2050. The office and land leases make up a significant portion of the Company’s operating lease activity. Many of these leases have one or more renewal options that allow the Company, at its discretion, to renew the lease for six months to seven years. Only renewal options that the Company believed were likely to be exercised were included in our lease calculations. Many land leases include minimum lease payments that increase when the related project becomes operational. In these cases, the commercial operation date was estimated by the Company and used to calculate the estimated minimum lease payments.

The Company also enters into leases for IT equipment and service agreements, automobiles, and other leases related to our construction projects such as equipment, mobile trailers and other temporary structures. The Company utilizes the portfolio approach for this class of lease. These leases are either short-term in nature or immaterial.

A portion of the Company’s real estate leases are generally subject to annual changes in the Consumer Price Index (“CPI”). The Company utilized each lease’s minimum lease payments to calculate the lease balances upon transition. The subsequent increases in rent based on changes in CPI were excluded and will be excluded for future leases from the calculation of the lease balances, but will be recorded to the condensed consolidated statements of income as part of our operating lease costs.

The Company has elected the practical expedient to not separate lease and non-lease components for existing leases for real estate and land leases. The Company has historical leases under ASC 840, Leases, which may have lease and non-lease components. Upon adoption of Topic 842, the Company has elected to continue to account for these historical leases as a single component, as permitted by Topic 842. As of January 1, 2019, as it relates to all prospective leases, the Company will allocate

(in thousands, except per share amounts)

consideration to lease and non-lease components based on pricing information in the respective lease agreement, or, if this information is not available, the Company will make a good faith estimate based on the available pricing information at the time of the lease agreement.

The discount rate was calculated using an incremental borrowing rate based on financing rates on secured comparable notes with comparable terms and a synthetic credit rating calculated by a third party. The Company elected to apply the discount rate using the remaining lease term at the date of adoption.

The Company has a number of leases that are classified as financing leases, which relate to transactions that are considered sale-leasebacks under ASC 840. See the sale-leaseback section below for additional information on the Company’s financing leases.

The Company has determined that certain power purchase agreements (“PPAs”) contain a lease component in accordance with ASC 840, Leases. The Company recognized $2,040 and $4,285 of operating lease revenue under these agreements during the three and six months ended June 30, 2020, respectively, which was reflected in revenues on the condensed consolidated statements of income. The Company recognized $2,271 and $4,495 of operating lease revenue under these agreements during the three and six months ended June 30, 2019, respectively, which was reflected in revenues on the condensed consolidated statements of income.

Sale-Leaseback

For solar photovoltaic (“solar PV”) projects that the Company has determined not to be integral equipment, the Company then determines if the leaseback should be classified as a financing lease or an operating lease. All solar PV projects sold to date under the sale-leaseback program have been determined by the Company to be financing leases. For leasebacks classified as financing leases, the Company initially records a financing lease asset and financing lease obligation in its condensed consolidated balance sheets equal to the lower of the present value of the Company’s future minimum leaseback payments or the fair value of the solar PV project. For financing leasebacks, the Company defers any gain or loss, representing the excess or shortfall of cash received from the investor compared to the net book value of the asset in the Company’s condensed consolidated balance sheets at the time of the sale. The Company records the long term portion of any deferred gain or loss in other liabilities and other assets, respectively, and the current portion of any deferred gain and loss in accrued expenses and other current liabilities and prepaid expenses and other current assets, respectively, in its condensed consolidated balance sheets and amortizes the deferred amounts over the lease term in cost of revenues in its condensed consolidated statements of income. Net amortization expense in cost of revenues related to deferred gains and losses was $57 and $58 of net gains for the three months ended June 30, 2020 and 2019, respectively. Net amortization expense in cost of revenues related to deferred gains and losses was $112 and $115 of net gains for the six months ended June 30, 2020 and 2019, respectively.

During the third quarter of 2018, the Company entered into an agreement with an investor which gives us the option to sell and contemporaneously lease back solar PV projects through August 2019 up to a maximum funding amount of $100.0 million. In January 2020, the Company amended the August 2018 agreement with the investor to extend the end date of the agreement to November 24, 2020 and increase the maximum funding amount up to $150.0 million. During the six months ended June 30, 2020, the Company did not complete any acquisitions of solar PV projects and $131.0 million remained available under the lending commitment.

9. COMMITMENTS AND CONTINGENCIES

The Company from time to time issues letters of credit and performance bonds, with their third-party lenders, to provide collateral. The Company also has future lease commitments which do not yet meet the criteria of a ROU asset or ROU liability as of June 30, 2020, for certain business offices. These commitments total $1,225 as of June 30, 2020 and relate to payments through 2026.

Legal Proceedings

The Company is involved in a variety of claims and other legal proceedings generally incidental to its normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, the Company does not believe the ultimate resolution of any of these existing matters would have a material adverse effect on its financial condition or results of operations.

Commitments as a Result of Acquisitions

In August 2018, the Company completed an acquisition which provided for a revenue earn-out contingent upon the acquired business meeting certain cumulative revenue targets over five years from the acquisition date. The Company evaluated financial forecasts of the acquired business and concluded that the fair value of this earn-out was approximately $555, which was subsequently increased to $678 as of December 31, 2019 which remained consistent at June 30, 2020, and is recorded in the other liabilities on the condensed consolidated balance sheets. The contingent consideration will be paid annually, commencing in 2020, if any of the cumulative revenue targets are achieved. The fair value of the earn-out will be re-evaluated at each reporting period and adjustments will be recorded as needed. See Note 10 for additional information.

In November 2018, the Company completed an acquisition of certain lease options, which provided for an earn-out if the lease option is exercised and if certain financial metrics are achieved. The Company evaluated the acquired lease options and concluded that the fair-value of this contingent liability was approximately $363, which was subsequently increased to $378 at December 31, 2019 which remained consistent at June 30, 2020, and is recorded in accrued expenses and other current liabilities and other liabilities on the condensed consolidated balance sheets. Payments will be made when milestones are achieved. The contingent liability will be re-evaluated at each reporting period and adjustments will be recorded as needed.

In April 2020, the Company completed an acquisition which provided for a profit earn-out contingent upon the acquired project meeting certain financial return targets. The Company evaluated the financial forecasts of the acquired asset and concluded that fair value of the earn-out was $0 at completion of the acquisition which will be re-evaluated at each reporting period. The contingent consideration will be paid annually beginning in 2021, if the financial return targets are achieved.

10. FAIR VALUE MEASUREMENT

The Company recognizes certain financial assets and liabilities at fair value on a recurring basis (at least annually). Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Three levels of inputs that may be used to measure fair value are as follows:

Level 1: Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.

Level 2: Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3: Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques.

The following table presents the input level used to determine the fair values of the Company’s financial instruments measured at fair value on a recurring basis:


		Fair Value as of
		June 30,		December 31,
	Level	2020		2019
Assets:
Interest rate swap instruments	2	$	—	$	15
Commodity swap instruments	2	151		198
Total assets		$	151	$	213
Liabilities:
Interest rate swap instruments	2	$	11,679	$	6,236

Interest make-whole provisions	2	1,388		918
Contingent consideration	3	678		678
Total liabilities		$	13,745	$	7,832

The fair value of the Company’s interest rate swaps was determined using cash flow analysis on the expected cash flow of the contract in combination with observable market-based inputs, including interest rate curves and implied volatilities. As part of this valuation, the Company considered the credit ratings of the counterparties to the interest rate swaps to determine if a credit risk adjustment was required.

The fair value of the Company’s commodity swaps was determined using a cash flow analysis on the expected cash flow of the contract in combination with observable forward price inputs obtained from a third-party pricing source. As part of this valuation, the Company considered the credit ratings of the counterparties to the commodity swaps to determine if a credit risk adjustment was required.

The fair value of the Company’s make-whole provisions were determined by comparing them against the rates of similar debt instruments under similar terms without a make-whole provision obtained from various highly rated third-party pricing sources.

The fair value of the Company’s contingent consideration liabilities were determined by evaluating the acquired asset’s future financial forecasts and evaluating which, if any, of the cumulative revenue targets, financial metrics and/or milestones are likely to be met. The Company has classified contingent consideration related to certain acquisitions within level 3 of the fair value hierarchy because the fair value is derived using significant unobservable inputs, which include discount rates and probability-weighted cash flows. The Company determined the fair value of its contingent consideration obligations based on a probability-weighted income approach derived from financial performance estimates and probability assessments of the

(in thousands, except per share amounts)

attainment of certain targets. The Company establishes discount rates to be utilized in its valuation models based on the cost to borrow that would be required by a market participant for similar instruments.

The key assumptions as of June 30, 2020, related to the contingent consideration from the acquisition of certain assets of Chelsea Group Limited, used in the model include a discount rate of 18% for purposes of discounting the low and base case scenarios associated with achievement of the financial based earn-out. The probabilities assigned to these scenarios were 50% for both the low and base case scenarios. An increase or decrease in the probability of achievement of any scenario could result in a significant increase or decrease to the estimated fair value of the contingent consideration liability.

The following table sets forth a summary of changes in fair value of contingent liabilities classified as Level 3 for the six months ended June 30, 2020 and June 30, 2019:


	Six Months Ended		Six Months Ended
	June 30, 2020		June 30, 2019
Contingent consideration liabilities balance at December 31, 2019 and 2018	$	678	$	600

Changes in the fair value of contingent consideration obligation	—		25
Contingent consideration liabilities balance at June 30, 2020 and 2019	$	678	$	625

The fair value of financial instruments is determined by reference to observable market data and other valuation techniques, as appropriate. The only category of financial instruments where the difference between fair value and recorded book value is notable is long-term debt. At June 30, 2020 and December 31, 2019 the fair value of the Company’s long-term debt was estimated using discounted cash flows analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two or level three financial instruments for the six months ended June 30, 2020 and the year ended December 31, 2019.

Based on the analysis performed, the fair value and the carrying value of the Company’s long-term debt, excluding financing leases, are as follows:


	As of June 30, 2020						As of December 31, 2019

12. INVESTMENT FUNDS AND OTHER VARIABLE INTEREST ENTITIES

Investment Funds

In each of September 2015, June 2017, June 2018, October 2018, and December 2019, the Company formed an investment fund with a different third-party investor which granted the applicable investor ownership interests in the net assets of certain of the Company’s renewable energy project subsidiaries. The Company currently has five such investment funds each with a different third-party investor.

The Company consolidates the investment funds, and all inter-company balances and transactions between the Company and the investment funds are eliminated in its condensed consolidated financial statements. The Company determined that the investment funds meet the definition of a variable interest entity (“VIE”). The Company uses a qualitative approach in assessing the consolidation requirement for VIEs that focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.

The Company has considered the provisions within the contractual arrangements that grant it power to manage and make decisions that affect the operation of these VIEs, including determining the solar energy systems and associated long term

Table of Contents

AMERESCO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)

(in thousands, except per share amounts)

customer contracts to be sold or contributed to the VIEs, and installation, operation and maintenance of the solar energy systems. The Company considers that the rights granted to the other investors under the contractual arrangements are more protective in nature rather than participating rights. As such, the Company has determined it is the primary beneficiary of the VIEs for all periods presented. The Company evaluates its relationships with VIEs on an ongoing basis to ensure that it continues to be the primary beneficiary.

Under the related agreements, cash distributions of income and other receipts by the funds, net of agreed-upon expenses and estimated expenses, tax benefits and detriments of income and loss, and tax benefits of tax credits, are assigned to the funds’ investor and Company’s subsidiaries as specified in contractual arrangements. Certain of these arrangements have call and put options to acquire the investor’s equity interest as specified in the contractual agreements. See Note 13 for additional information on the call and put options.

A summary of amounts related to the investment funds in the Company’s condensed consolidated balance sheets is as follows:


	June 30,		December 31,
	2020⁽¹⁾		2019⁽¹⁾
Cash and cash equivalents	$	7,138	$	4,666

⁽¹⁾The amounts in the above table are reflected in Note 1 on the Company’s condensed consolidated balance sheets. See the Company’s condensed consolidated balance sheets for additional information.

Other Variable Interest Entities

The Company follows guidance on the consolidation of VIEs that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint ventures economic performance, including powers granted to the joint ventures program manager, powers contained in the joint venture governing board and, to a certain extent, a company's economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:

Table of Contents

AMERESCO, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)

(in thousands, except per share amounts)

•a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or

•a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.

Many of the joint ventures are deemed to be VIEs because they lack sufficient equity to finance the activities of the joint venture.

Unconsolidated joint ventures are accounted for under the equity method. For those joint ventures, the Company's investment balances for the joint venture are included in other assets on the condensed consolidated balance sheets and the Company’s pro rata share of net income or loss is included in operating income. The Company’s investments in equity method joint ventures on the condensed consolidated balance sheets as of June 30, 2020 and December 31, 2019 was a net asset of $1,342 and $1,292, respectively. During the three and six months ended June 30, 2020, the Company recognized expense of $24 and $77, respectively, from equity method joint ventures. During the three and six months ended June 30, 2019, the Company recognized expense of $74 from equity method joint ventures.

13. NON-CONTROLLING INTERESTS AND EQUITY

Redeemable Non-controlling Interests

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the third quarter of 2015 has the right, beginning on the fifth anniversary of the final funding of the variable rate construction and term loans due 2023 and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund, which was formed in the third quarter of 2015, also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2017 has the right, beginning on the fifth anniversary of the final funding of the non-controlling interest holder and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2017 also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2018 has the right, beginning on the fifth anniversary of the investment fund’s final project being placed into service and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2018 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2019 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned

subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2019 also includes a right, beginning six months after the fifth anniversary of the final funding and extending for one year, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option.

The purchase price for two of the investment funds investors’ interests under the call options is equal to the fair market value of such interest at the time the option is exercised. The purchase price for two of the investment funds investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 7% of the investors’ contributed capital balance at the time the option is exercisable. The purchase price for the remaining investment fund investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 5% of the investors’ contributed capital balance at the time the option is exercisable. The call options are exercisable beginning on the date that specified conditions are met for each respective fund. None of the call options are expected to become exercisable prior to 2021.

The purchase price for two of the funds investors’ interests in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and a specified amount, ranging from $659 - $917. The purchase price for the two of the remaining funds investors’ interest in the investment funds under the put options is the sum of (i) the fair market value at the time the option is exercised, and (ii) the closing costs incurred by the investor in connection with the exercise of the put option. The purchase price for the remaining fund investors’ interest in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and the sum of (i) 5% of the investors’ contributed capital balance at the time the option is exercisable, and (ii) the fair market value of any unpaid tax law change losses incurred by the investor in connection with the exercise of the put option. The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund. The put options are not expected to become exercisable prior to 2022.

Because the put options represents redemption features that are not solely within the control of the Company, the non-controlling interests in these funds are presented outside of permanent equity. Redeemable non-controlling interests are reported using the greater of their carrying value at each reporting date (which is impacted by attribution under the hypothetical liquidation at book value method) or their estimated redemption value in each reporting period. At both June 30, 2020 and December 31, 2019 redeemable non-controlling interests were reported at their carrying value totaling $36,303 and $31,616, respectively, as the carrying value at each reporting period was greater than the estimated redemption value.

14. EARNINGS PER SHARE AND OTHER EQUITY RELATED INFORMATION

Earnings Per Share

Basic earnings per share is calculated using the Company’s weighted-average outstanding common shares, including vested restricted shares. When the effects are not anti-dilutive, diluted earnings per share is calculated using the weighted-average outstanding common shares; the dilutive effect of convertible preferred stock, under the “if converted” method; and the treasury stock method with regard to warrants and stock options; all as determined under the treasury stock method.


	Three Months Ended June 30,						Six Months Ended June 30,
	2020		2019		2020		2019
Net income attributable to common shareholders	$	4,365	$	9,216	$	10,566	$	13,363
Basic weighted-average shares outstanding	47,488		46,387		47,500		46,340
Effect of dilutive securities:
Stock options	1,031		1,294		1,071		1,326
Diluted weighted-average shares outstanding	48,519		47,681		48,571		47,666

For the three months ended June 30, 2020 and 2019, the total number of shares of common stock related to stock options excluded from the calculation of dilutive shares, as the effect would be anti-dilutive, were 1,450 and 446, respectively. For the six months ended June 30, 2020 and 2019, the total number of shares of common stock related to stock options excluded from the calculation of dilutive shares, as the effect would be anti-dilutive, were 1,388 and 372, respectively.

The Company’s 2020 Stock Incentive Plan (the “2020 Plan”), was adopted by the Company’s Board of Directors in February 2020 and approved by its stockholders in May 2020. The 2020 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards and other stock-based awards. Upon its effectiveness, 5,000 shares of the Company’s Class A common stock were reserved for issuance under the 2020 Plan. As of June 30, 2020, the Company had granted options to purchase 85 shares of Class A common stock under the 2020 Plan.

In May 2020, the Company amended its 2017 Employee Stock Purchase Plan ("ESPP") which permits eligible employees to purchase up to an aggregate of 350 shares of the Company’s Class A common stock. This plan commenced December 1, 2017 and was previously amended on August 2018. The ESPP allows participants to purchase shares of common stock at a 5% discount from the fair market value of the stock as determined on specific dates at six-month intervals. During the six months ended June 30, 2020 and 2019, the Company issued 28 and 22 shares, respectively, under the ESPP.

Stock-Based Compensation Expense

For the three months ended June 30, 2020 and 2019, the Company recorded stock-based compensation expense, including expense related to the ESPP, of $430 and $397, respectively, in connection with the stock-based payment awards. For the six months ended June 30, 2020 and 2019, the Company recorded stock-based compensation expense, including expense related to the ESPP, of $859 and $782, respectively, in connection with the stock-based payment awards. The compensation expense is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income. As of June 30, 2020, there was $11,167 of unrecognized compensation expense related to non-vested stock option awards that is expected to be recognized over a weighted-average period of 2.8 years.

No awards to individuals who were not either an employee or director of the Company were granted during the six months ended June 30, 2020 or during the year ended December 31, 2019.

Stock Option Grants

During the three months ended June 30, 2020, the Company granted 85 common stock options to certain employee and directors under its 2020 Stock Incentive Plan, which have a contractual life of ten years and vest over a five-year period. During the six months ended June 30, 2020, the Company granted 281 common stock options to certain employees and directors under its 2010 and 2020 Stock Incentive Plan, which have a contractual life of ten years and vest over a five-year period.

Share Repurchase Program

In April 2016, the Company’s Board of Directors authorized the repurchase of up to $10,000 of the Company’s Class A common stock from time to time on the open market in privately negotiated transactions. The Company’s Board of Directors authorized an increase in the Company’s share repurchase authorization to $15,000 of the Company's Class A common stock in February 2017 and to $17,553 of the Company's Class A common stock in August 2019, in each case, from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased will be determined by the Company's management based on its evaluation of market conditions and other factors. Any repurchased shares will be available for use in connection with its stock plans and for other corporate purposes. The repurchase program has and will be funded using the Company's working capital and borrowings under its revolving line of credit. The Company accounts for share repurchases using the cost method. Under this method, the cost of the share repurchase is recorded entirely in treasury stock, a contra equity account. During the six months ended June 30, 2020, the Company repurchased an immaterial amount of shares of common stock. During the six months ended June 30, 2019, the Company did not repurchase any shares of common stock.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 2019 included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed on March 4, 2020 with the U.S. Securities and Exchange Commission (“SEC”). This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Forward looking statements include statements regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans, objectives of management, expected market growth and other characterizations of future events or circumstances. All statements, other than statements of historical fact, including statements that refer to our expectations as to the future growth of our business and associated expenses; our expectations as to revenue generation; the future availability of borrowings under our revolving credit facility; the expected future growth of the market for energy efficiency and renewable energy solutions; our backlog, awarded projects and recurring revenue and the timing of such matters; our expectations as to acquisition activity; the impact of any restructuring; the uses of future earnings; our intention to repurchase shares of our Class A common stock; the expected energy and cost savings of our projects; and the expected energy production capacity of our renewable energy plants; and other characterizations of future events or circumstances are forward-looking statements. Currently, one of the most significant factors, however, is the potential adverse effect of the current pandemic of the novel coronavirus, or COVID-19, on our financial condition, results of operations, cash flows and performance and the global economy and financial markets. The extent to which COVID-19 impacts us, suppliers, customers, employees and supply chains will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Moreover, you should interpret many of the risks identified in this report, as well as the risks set forth below, as being heightened as a result of the ongoing and numerous adverse impacts of COVID-19. Forward looking statements are often, but not exclusively, identified by the use of words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” “target,” “project,” “predict” or “continue,” and similar expressions or variations. These forward-looking statements are based on current expectations and assumptions that are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially and adversely from future results expressed or implied by such forward-looking statements. Risks, uncertainties and factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled “Risk Factors,” set forth in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019 and Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020. The forward-looking statements in this Quarterly Report on Form 10-Q represent our views as of the date of this Quarterly Report on Form 10-Q. Subsequent events and developments may cause our views to change. However, while we may elect to update these forward looking statements at some point in the future, we have no current intention of doing so and undertake no obligation to do so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report on Form 10-Q.

Overview

Ameresco is a leading provider of energy efficiency solutions for facilities throughout North America and Europe. We provide solutions that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. Our comprehensive set of services includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants.

In addition to organic growth, strategic acquisitions of complementary businesses and assets have been an important part of our historical development. Since inception, we have completed numerous acquisitions, which have enabled us to broaden our service offerings and expand our geographical reach.

COVID-19 Update

In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including how it will impact our suppliers, customers, employees and supply chains. While we did not incur significant disruptions during the six months ended June 30, 2020 from the COVID-19 pandemic, we are unable to predict the impact that the COVID-19 pandemic will have on our financial condition, results of operations and cash flows due to numerous uncertainties. These uncertainties include the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact and the direct and indirect economic effects of the pandemic and containment measures, among others.

Table of Contents

Further, the overall impact of COVID-19 on our condensed consolidated results of operations for the six months ended June 30, 2020 was not material. However, the impact that COVID-19 will have on our consolidated results of operations throughout 2020 remains uncertain. We expect to experience delays in our project award conversions and potential construction slowdowns as a result of known shelter-in-place restrictions. We will continue to evaluate the nature and extent of these potential impacts to our business, consolidated results of operations, segment results, liquidity and capital resources.

Effects of Seasonality

We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenues and operating income in the third and fourth quarter are typically higher, and our revenues and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenues or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.

Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results.” in Item 1A, Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2019 (“Annual Report”), and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.

Backlog and Awarded Projects

Total construction backlog represents projects that are active within our ESPC sales cycle. Our sales cycle begins with the initial contact with the customer and ends, when successful, with a signed contract, also referred to as fully-contracted backlog. Our sales cycle recently has been averaging 18 to 54 months. Awarded backlog is created when a potential customer awards a project to Ameresco following a request for proposal. Once a project is awarded but not yet contracted, we typically conduct a detailed energy audit to determine the scope of the project as well as identify the savings that may be expected to be generated from upgrading the customer’s energy infrastructure. At this point, we also determine the sub-contractor, what equipment will be used, and assist in arranging for third party financing, as applicable. Recently, awarded projects have been taking an average of 12 to 24 months to result in a signed contract and convert to fully-contracted backlog. It may take longer, however, depending upon the size and complexity of the project. Historically, approximately 90% of our awarded backlog projects have resulted in a signed contract. After the customer and Ameresco agree to the terms of the contract and the contract becomes executed, the project moves to fully-contracted backlog. The contracts reflected in our fully-contracted backlog typically have a construction period of 12 to 36 months and we typically expect to recognize revenue for such contracts over the same period. Fully-contracted backlog begins converting into revenues generated from backlog over time using cost based input methods once construction has commenced. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our Annual Report, and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expense and related disclosures. The most significant estimates with regard to these condensed consolidated financial statements relate to our estimates of final construction contract profit in accordance with accounting for long-term contracts under the revenue recognition requirements of contracts with our customers, allowance for credit losses, inventory reserves, realization of project development costs, leases, fair value of derivative financial instruments, accounting for business acquisitions, stock-based awards, impairment of long-lived assets and goodwill, income taxes, self insurance reserves and potential liability in conjunction with certain commitments and contingencies. Actual results could differ from those estimates.

Such estimates and assumptions are based on historical experience and on various other factors that management believes to be reasonable under the circumstances. Estimates and assumptions are made on an ongoing basis, and accordingly, the actual results may differ from these estimates under different assumptions or conditions.

The following are certain critical accounting policies that, among others, affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements:

•Revenue Recognition;

•Energy Assets;

•Leases;

•Goodwill and Intangible Assets;

•Derivative Financial Instruments; and

•Variable Interest Entities.

Further details regarding our critical accounting policies and estimates can be found in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report. In addition, please refer to Note 2, “Summary of Significant Accounting Policies,” of our Notes to the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s Annual Report. The Company has determined that no material changes concerning our critical accounting policies have occurred since December 31, 2019.

Income Before Taxes

Income before taxes decreased $0.5 million, or 5.1%, to $8.8 million for the three months ended June 30, 2020 compared to the same period of 2019, due to the reasons described above. Income before taxes increased $0.5 million, or 4.3%, to $13.0 million for the six months ended June 30, 2020 compared to the same period of 2019, due to the reasons described above.

Provision (Benefit) from Income Taxes

The benefit for income taxes was $0 for the three months ended June 30, 2020, compared to a provision of $0.8 million for the three months ended June 30, 2019. The estimated effective annualized tax rate impacted by period discrete items applied for the three months ended June 30, 2020 was 0% of benefit compared to 8.6% of provision for the three months ended June 30, 2019.

The benefit for income taxes was ($2.5) million for the six months ended June 30, 2020, compared to a provision of $1.1 million for the six months ended June 30, 2019. The estimated effective annualized tax rate impacted by period discrete items applied for the six months ended June 30, 2020 was (19.3)% of benefit compared to 8.5% of provision for the six months ended June 30, 2019.

The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2020 were the effects of investment tax credits to which the Company is entitled from solar plants which have been placed into service or are forecasted to be placed into service during 2020, tax deductions related to Section 179D deduction, tax basis adjustments on certain partnership flip transactions and tax rate benefits associated with net operating loss carrybacks made possible by the passing of CARES Act on March 27, 2020. The principal reason for the difference between the statutory rate and the estimated annual effective rate for 2019 were the effects of investment tax credits to which the Company is entitled from solar plants which were placed into service or were forecasted to be placed into service during 2019. We estimate the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 , an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback provides an additional refund of approximately $3,600 related to Alternative Minimum Tax.

The investment tax credits and production tax credits to which the Company may be entitled fluctuate from year to year based on the cost of the renewable energy plants the Company places or expects to place in service and production levels at Company owned facilities in the respective year. As part of the Tax Extender and Disaster Relief Act of 2019, signed into law December 20, 2019 Section 179D was extended through December 31, 2020.

Unallocated corporate activity includes all corporate level selling, general and administrative expenses and other expenses not allocated to the segments. We do not allocate any indirect expenses to the segments.

Liquidity and Capital Resources

Sources of liquidity. Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects and various forms of debt. We believe that the cash and cash equivalents and availability under our revolving senior secured credit facility, combined with our access to credit markets, will be sufficient to fund our operations through the next twelve months and thereafter. See Note 2 of the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s Annual Report.

We believe we have sufficient liquidity to satisfy our cash needs, however, we continue to evaluate and take action, as necessary, to preserve adequate liquidity and ensure that our business can continue to operate during these uncertain times. This includes limiting discretionary spending across the organization and re-prioritizing our capital projects amid the COVID-19 pandemic.

payment delay of employer payroll taxes during 2020 after the date of enactment. We estimate the payment of approximately $5.0 million of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). We estimate the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 , an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.

Proceeds from our Federal ESPC projects are generally received through agreements to sell the ESPC receivables related to certain ESPC contracts to third-party investors. We use the advances from the investors under these agreements to finance the projects. Until recourse to us ceases for the ESPC receivables transferred to the investor, upon final acceptance of the work by the government customer, we are the primary obligor for financing received. The transfers of receivables under these agreements do not qualify for sales accounting until final customer acceptance of the work, so the advances from the investors are not classified as operating cash flows. Cash draws that we receive under these ESPC agreements are recorded as financing cash inflows. The use of the cash received under these arrangements to pay project costs is classified as operating cash flows. Due to the manner in which the ESPC contracts with the third-party investors are structured, our reported operating cash flows are materially impacted by the fact that operating cash flows only reflect the ESPC contract expenditure outflows and do not reflect any inflows from the corresponding contract revenues. Upon acceptance of the project by the federal customer the ESPC receivable and corresponding ESPC liability are removed from our condensed consolidated balance sheet as a non-cash settlement.

Our service offering also includes the development, construction and operation of small-scale renewable energy plants. Small-scale renewable energy projects, or energy assets, can either be developed for the portfolio of assets that we own and operate or designed and built for customers. Expenditures related to projects that we own are recorded as cash outflows from investing activities. Expenditures related to projects that we build for customers are recorded as cash outflows from operating activities as cost of revenues.

The amount of interest capitalized relating to construction financing during the period of construction for the six months ended June 30, 2020 and 2019 was $1.8 million and $1.6 million, respectively.

Cash flows from operating activities. Operating activities used $73.6 million of net cash during the six months ended June 30, 2020. During that period, we had net income of $15.5 million, which is net of non-cash compensation, depreciation, amortization, accretion, contingent consideration, deferred income taxes, net loss on derivatives, unrealized foreign exchange loss and other non-cash items totaling $28.3 million. Increases in project development costs, and decreases in accounts payable, accrued expenses and other current liabilities and income taxes payable used $55.4 million in cash. These were offset by decreases in accounts receivable including retainage, inventory, costs and estimated earnings in excess of billings, prepaid expenses and other current assets and other assets, and increases in billings in excess of cost and estimated earnings and other liabilities which provided for $27.8 million in cash. Increases in Federal ESPC receivables used an additional $89.8 million. As described above, Federal ESPC operating cash flows only reflect the ESPC expenditure outflows and do not reflect any inflows from the corresponding contract revenues, which are recorded as cash inflows from financing activities due to the timing of the receipt of cash related to the assignment of the ESPC receivables to the third-party investors.

Operating activities used $109.3 million of net cash during the six months ended June 30, 2019. During that period, we had net income of $11.4 million, which is net of non-cash compensation, depreciation, amortization, accretion, contingent consideration, deferred income taxes, gain on deconsolidation of a VIE, net gain on derivatives, unrealized foreign exchange loss and other non-cash items totaling $18.6 million. Increase in accounts receivable including retainage, inventory, costs and estimated earnings in excess of billings, prepaid expenses and other current assets, project development costs and other assets, and decreases in accounts payable, accrued expenses and other current liabilities, billings in excess of costs and estimated earnings and other liabilities used $80.1 million in cash. These were offset by an increase in income tax payable which provided for $2.7 million in cash. Increase in Federal ESPC receivables used an additional $61.8 million.

Cash flows from investing activities. Cash flows from investing activities during the six months ended June 30, 2020 used $78.7 million. We invested $77.2 million on purchases of energy assets during the six months ended June 30, 2020. In addition, we invested $1.4 million in purchases of other property and equipment, and made contributions of $0.1 million in an equity investment. We currently plan to invest approximately $110.0 million to $160.0 million in additional capital expenditures for the remainder of 2020, principally for the construction or acquisition of new renewable energy plants.

Table of Contents

Cash flows from investing activities during the six months ended June 30, 2019 used $50.7 million. We invested $46.5 million on purchases of energy assets during the six months ended June 30, 2019. In addition, we invested $2.8 million in purchases of other property and equipment, $1.3 million related to acquisitions of businesses and made contribution of $0.2 million in an equity investment.

Cash flows from financing activities. Cash flows from financing activities during the six months ended June 30, 2020 provided $142.4 million. This was primarily due to proceeds received from Federal ESPC projects and energy assets of $135.1 million, proceeds from exercises of stock options and ESPP of $5.1 million, net proceeds from our senior secured credit facility of $16.0 million, net proceeds from long-term debt financings of $14.2 million and net proceeds from redeemable non-controlling interests of $0.1 million. This was partially offset by payments on long-term debt of $25.9 million, and payments of financing fees of $2.2 million.

Cash flows from financing activities during the six months ended June 30, 2019 provided $135.7 million. This was primarily due to proceeds received from Federal ESPC projects and energy assets of $84.6 million, proceeds from exercises of stock options and ESPP of $1.3 million, net proceeds from our senior secured credit facility of $41.4 million, proceeds from long-term debt of $2.7 million and net contributions from redeemable non-controlling interests of $19.3 million. This was partially offset by payments on long-term debt of $13.2 million and payments of financing fees of $0.4 million.

We currently plan additional project financings of approximately $110.0 million to $160.0 million for the remainder of 2020 to fund the construction or acquisition of new renewable energy plants discussed above.

We may also, from time to time, finance our operations through issuance or offering of equity or debt securities.

On March 31, 2020, the Company executed an amendment to its fourth amended and restated bank credit facility. The amendment increased the total funded debt to EBITDA covenant ratio from a maximum of 3.25 to 3.75 for the fiscal quarters ending March 31, 2020 through December 31, 2020. The amendment also increased the Eurocurrency Rate floor to 1% from 0% previously. The total commitment under the amended credit facility (revolving credit, term loan and swing line) remains unchanged, which is $185,000, and the amendment did not result in any restructured payments.

See Note 16, Debt, of Notes to Condensed Consolidated Financial Statements for additional discussion of items impacting the Company’s liquidity.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheet.

AMERESCO, INC.

Incentive Stock Option Agreement

Granted Under 2020 Stock Incentive Plan

1. Grant of Option.

This agreement evidences the grant by Ameresco, Inc., a Delaware corporation (the “Company”), on _________ (the “Grant Date”), to _________, an employee of the Company (the “Participant”), of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s 2020 Stock Incentive Plan (the “Plan”), a total of _________ shares (the “Shares”) of Class A common stock, $0.0001 par value per share, of the Company at _________ per Share. Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on the date one day prior to the tenth anniversary of the Grant Date (the “Final Exercise Date”), provided that this option shall automatically terminate at 5:00 p.m., Eastern time, on the date set forth in the award notification to the Participant from the Company if the Corporation has not received before that time this agreement together with its standard form of employee non-competition agreement each executed by the Participant.

It is intended that the option evidenced by this agreement shall, to the extent permitted by applicable law, be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”). Except as otherwise indicated by the context, the term “Participant”, as used in this agreement, shall be deemed to include any person who acquires the right to exercise this option validly under its terms.

2. Vesting Schedule. This option will become exercisable (“vest”) as follows:


Shares			Vest Date

The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan.

3. Exercise of Option.

(a) Form of Exercise. To exercise this option, the Participant shall deliver to the Company at its principal office a notice of exercise in a form (which may be electronic) approved by the Company, accompanied by this agreement, and payment in full in the manner provided in the Plan. The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than ten whole shares.

(b)Continuous Relationship with the Company Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee or officer of, or consultant or advisor to, the Company or any parent or subsidiary of the Company as defined in Section 424(e) or (f) of the Code (an “Eligible Participant”).

(c) Termination of Relationship with the Company. If the Participant ceases to be an Eligible Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall be exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon written notice to the Participant from the Company describing such violation.

(d) Exercise Period Upon Death or Disability. If the Participant dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below, this option shall be exercisable, within the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date.

(e)Termination for Cause. If, prior to the Final Exercise Date, the Participant’s employment is terminated by the Company for Cause (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such termination of employment. If, prior to the Final Exercise Date, the Participant is given notice by the Company of the termination of his or her employment by the Company for Cause, and the effective date of such employment termination is subsequent to the date of delivery of such notice, the right to exercise this option shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment shall not be terminated for Cause as provided in such notice or (ii) the effective date of such termination of employment (in which case the right to exercise this option shall, pursuant to the preceding sentence, terminate upon the effective date of such termination of employment). If the Participant is party to an employment or severance agreement with the Company that contains a definition of “cause” for termination of employment, “Cause” shall have the meaning ascribed to such term in such agreement. Otherwise, “Cause” shall mean willful misconduct by the Participant or willful failure by the Participant to perform his or her responsibilities to the Company (including, without limitation, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure, non-competition or other similar agreement between the Participant and the Company), as determined by the Company, which determination shall be conclusive. The Participant’s employment shall be considered to have been terminated

for Cause if the Company determines, within 30 days after the Participant’s resignation, that termination for Cause was warranted.

4. Tax Matters.

(a) Withholding. No Shares will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company, or makes provision satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of this option.

(b) Disqualifying Disposition. If the Participant disposes of Shares acquired upon exercise of this option within two years from the Grant Date or one year after such Shares were acquired pursuant to exercise of this option, the Participant shall notify the Company in writing of such disposition.

5. Transfer Restrictions; Clawback.

(a) This option may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant.

(b) In accepting this option, the Participant agrees to be bound by any clawback policy that the Company has in place or may adopt in the future.

6. Provisions of the Plan.

This option is subject to the provisions of the Plan (including the provisions relating to amendments to the Plan), a copy of which is furnished to the Participant with this option.

IN WITNESS WHEREOF, the Company has caused this option to be executed under its corporate seal by its duly authorized officer. This option shall take effect as a sealed instrument.

Exhibit 10.8

Ameresco Inc.

2017 EMPLOYEE STOCK PURCHASE PLAN

as amended

The purpose of this 2017 Employee Stock Purchase Plan (this “Plan”) is to provide eligible employees of Ameresco Inc. (the “Company”) and certain of its subsidiaries with opportunities to purchase shares of the Company’s Class A common stock, $0.0001 par value per share (the “Common Stock”), commencing at the time set forth in the Plan. Subject to adjustment under Section 15 hereof, the number of shares of Common Stock that have been approved for this purpose is 350,000 shares of Common Stock.

This Plan is intended to qualify as an “employee stock purchase plan” as defined in Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations issued thereunder, and shall be interpreted consistent therewith.

1. Administration. The Plan will be administered by the Board of Directors of the Company (the “Board”) or by a Committee appointed by the Board (the “Committee”). The Board or the Committee has authority to make rules and regulations for the administration of the Plan and its interpretation and decisions with regard thereto shall be final and conclusive.

2. Eligibility. All employees of the Company and all employees of any subsidiary of the Company (as defined in Section 424(f) of the Code) designated by the Board or the Committee from time to time (a “Designated Subsidiary”), are eligible to participate in any one or more of the offerings of Options (as defined in Section 9) to purchase Common Stock under the Plan provided that:

(a) they are customarily employed by the Company or a Designated Subsidiary for more than twenty (20) hours a week and for more than five (5) months in a calendar year;

(b) they have been employed by the Company or a Designated Subsidiary for at least six (6) months prior to enrolling in the Plan; and

(c) they are employees of the Company or a Designated Subsidiary on the first day of the applicable Plan Period (as defined below).

No employee may be granted an Option hereunder if such employee, immediately after the Option is granted, owns 5% or more of the total combined voting power or value of the stock of the Company or any subsidiary. For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code shall apply in determining the stock ownership of an employee, and all stock that the employee has a contractual right to purchase shall be treated as stock owned by the employee.

The Company retains the discretion to determine which eligible employees may participate in an offering pursuant to and consistent with Treasury Regulation Sections 1.423-2(e) and (f).

3. Offerings. The Company will make two offerings in a twelve month period (“Offerings”) to employees to purchase stock under this Plan. Offerings will begin each June 1 and December 1, or the first business day thereafter (such dates, the “Offering Commencement Dates”). Each Offering Commencement Date will begin a six (6) month period (a “Plan Period”)

during which payroll deductions will be made and held for the purchase of Common Stock at the end of the Plan Period. The Board or the Committee may, at its discretion, choose a different Plan Period of not more than twelve (12) months for Offerings.

4. Participation. An employee eligible on the Offering Commencement Date of any Offering may participate in such Offering by completing and forwarding either a written or electronic payroll deduction authorization form to the employee’s appropriate payroll office at least ten (10) days prior to the applicable Offering Commencement Date. The form will authorize a regular payroll deduction from the Compensation received by the employee during the Plan Period. Unless an employee files a new form or withdraws from the Plan, his or her deductions and purchases will continue at the same rate for future Offerings under the Plan as long as the Plan remains in effect. The term “Compensation” means the amount of money reportable on the employee’s Federal Income Tax Withholding Statement, excluding overtime, shift premium, incentive or bonus awards, allowances and reimbursements for expenses such as relocation allowances for travel expenses, income or gains associated with the grant or vesting of restricted stock, income or gains on the exercise of Company stock options or stock appreciation rights, and similar items, whether or not shown or separately identified on the employee’s Federal Income Tax Withholding Statement, but including, in the case of salespersons, sales commissions to the extent determined by the Board or the Committee.

5. Deductions. The Company will maintain payroll deduction accounts for all participating employees. With respect to any Offering made under this Plan, an employee may authorize a payroll deduction in any percentage amount (in whole percentages) up to a maximum of fifteen (15)% of the Compensation he or she receives during the Plan Period or such shorter period during which deductions from payroll are made. The Board or the Committee may, at its discretion, designate a lower maximum contribution rate. The minimum payroll deduction is such percentage of Compensation as may be established from time to time by the Board or the Committee.

6. Deduction Changes. An employee may decrease or discontinue his or her payroll deduction once during any Plan Period, by filing either a written or electronic new payroll deduction authorization form. However, an employee may not increase his or her payroll deduction during a Plan Period. If an employee elects to discontinue his or her payroll deductions during a Plan Period, but does not elect to withdraw his or her funds pursuant to Section 8 hereof, funds deducted prior to his or her election to discontinue will be applied to the purchase of Common Stock on the Exercise Date (as defined below).

7. Interest. Interest will not be paid on any employee accounts, except to the extent that the Board or the Committee, in its sole discretion, elects to credit employee accounts with interest at such rate as it may from time to time determine.

8. Withdrawal of Funds. An employee may at any time prior to the close of business on the fifteenth business day prior to the end of a Plan Period and for any reason permanently draw out the balance accumulated in the employee’s account and thereby withdraw from participation in an Offering. Partial withdrawals are not permitted. The employee may not begin participation again during the remainder of the Plan Period during which the employee withdrew his or her

balance. The employee may participate in any subsequent Offering in accordance with terms and conditions established by the Board or the Committee.

9. Purchase of Shares.

(a) Number of Shares. On the Offering Commencement Date, the Company will grant to each eligible employee who is then a participant in the Plan an option (an “Option”) to purchase on the last business day of such Plan Period (the “Exercise Date”) at the applicable purchase price (the “Option Price”) up to that number of shares of Common Stock determined by multiplying $2,083 by the number of full months in the Plan Period and dividing the result by the closing price (as determined below) on the Offering Commencement Date; provided, however, that no employee may be granted an Option which permits his or her rights to purchase Common Stock under this Plan and any other employee stock purchase plan (as defined in Section 423(b) of the Code) of the Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value of such Common Stock (determined at the date such Option is granted) for each calendar year in which the Option is outstanding at any time; and, provided, further, however, that the Committee may, in its discretion, set a fixed maximum number of shares of Common Stock that each eligible employee may purchase per Plan Period which number may not be greater than the number of shares of Common Stock determined by using the formula in the first clause of this Section 9(a) and which number shall be subject to the second clause of this Section 9 (a).

(b) Option Price. The Board or the Committee shall determine the Option Price for each Plan Period, including whether such Option Price shall be determined based on the lesser of the closing price of the Common Stock on (i) the first business day of the Plan Period or (ii) the Exercise Date, or shall be based solely on the closing price of the Common Stock on the Exercise Date; provided, however, that such Option Price shall be at least 85% of the applicable closing price. In the absence of a determination by the Board or the Committee, the Option Price will be 95% of the lesser of the closing price of the Common Stock on (i) the first business day of the Plan Period or (ii) the Exercise Date. The closing price shall be (a) the closing price (for the primary trading session) on any national securities exchange on which the Common Stock is listed or (b) the average of the closing bid and asked prices in the over-the-counter-market, whichever is applicable, as published in The Wall Street Journal or another source selected by the Board or the Committee. If no sales of Common Stock were made on such a day, the price of the Common Stock shall be the reported price for the next preceding day on which sales were made.

(c) Exercise of Option. Each employee who continues to be a participant in the Plan on the Exercise Date shall be deemed to have exercised his or her Option at the Option Price on such date and shall be deemed to have purchased from the Company the number of whole shares of Common Stock reserved for the purpose of the Plan that his or her accumulated payroll deductions on such date will pay for, but not in excess of the maximum numbers determined in the manner set forth above.

(d) Return of Unused Payroll Deductions. Any balance remaining in an employee’s payroll deduction account at the end of a Plan Period will be automatically refunded to the employee.

10. Issuance of Certificates. Certificates representing shares of Common Stock purchased under the Plan may be issued only in the name of the employee, in the name of the employee and another person of legal age as joint tenants with rights of survivorship, or (in the

Company’s sole discretion) in the name of a brokerage firm, bank, or other nominee holder designated by the employee. The Company may, in its sole discretion and in compliance with applicable laws, authorize the use of book entry registration of shares in lieu of issuing stock certificates.

11. Rights on Retirement, Death or Termination of Employment. If a participating employee’s employment ends before the last business day of a Plan Period, no payroll deduction shall be taken from any pay then due and owing to the employee and the balance in the employee’s account shall be paid to the employee. In the event of the employee’s death before the last business day of a Plan Period, the Company shall, upon notification of such death, pay the balance of the employee’s account (a) to the executor or administrator of the employee’s estate or (b) if no such executor or administrator has been appointed to the knowledge of the Company, to such other person(s) as the Company may, in its discretion, designate. If, before the last business day of the Plan Period, the Designated Subsidiary by which an employee is employed ceases to be a subsidiary of the Company, or if the employee is transferred to a subsidiary of the Company that is not a Designated Subsidiary, the employee shall be deemed to have terminated employment for the purposes of this Plan.

12. Optionees Not Stockholders. Neither the granting of an Option to an employee nor the deductions from his or her pay shall make such employee a stockholder of the shares of Common Stock covered by an Option under this Plan until he or she has purchased and received such shares.

13. Options Not Transferable. Options under this Plan are not transferable by a participating employee other than by will or the laws of descent and distribution, and are exercisable during the employee’s lifetime only by the employee.

14. Application of Funds. All funds received or held by the Company under this Plan may be combined with other corporate funds and may be used for any corporate purpose.

15. Adjustment for Changes in Common Stock and Certain Other Events.

(a) Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, (i) the number and class of securities available under this Plan, (ii) the share limitations set forth in Section 9, and (iii) the Option Price shall be equitably adjusted to the extent determined by the Board or the Committee.

(b) Reorganization Events.

(1) Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer or disposition of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any liquidation or dissolution of the Company.

(2) Consequences of a Reorganization Event on Options. In connection with a Reorganization Event, the Board or the Committee may take any one or more of the following actions as to outstanding Options on such terms as the Board or the Committee determines: (i)

provide that Options shall be assumed, or substantially equivalent Options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to employees, provide that all outstanding Options will be terminated immediately prior to the consummation of such Reorganization Event and that all such outstanding Options will become exercisable to the extent of accumulated payroll deductions as of a date specified by the Board or the Committee in such notice, which date shall not be less than ten (10) days preceding the effective date of the Reorganization Event, (iii) upon written notice to employees, provide that all outstanding Options will be cancelled as of a date prior to the effective date of the Reorganization Event and that all accumulated payroll deductions will be returned to participating employees on such date, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Reorganization Event (the “Acquisition Price”), change the last day of the Plan Period to be the date of the consummation of the Reorganization Event and make or provide for a cash payment to each employee equal to (A) (1) the Acquisition Price times (2) the number of shares of Common Stock that the employee’s accumulated payroll deductions as of immediately prior to the Reorganization Event could purchase at the Option Price, where the Acquisition Price is treated as the fair market value of the Common Stock on the last day of the applicable Plan Period for purposes of determining the Option Price under Section 9(b) hereof, and where the number of shares that could be purchased is subject to the limitations set forth in Section 9(a), minus (B) the result of multiplying such number of shares by such Option Price, (v) provide that, in connection with a liquidation or dissolution of the Company, Options shall convert into the right to receive liquidation proceeds (net of the Option Price thereof) and (vi) any combination of the foregoing.

For purposes of clause (i) above, an Option shall be considered assumed if, following consummation of the Reorganization Event, the Option confers the right to purchase, for each share of Common Stock subject to the Option immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise of Options to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determines to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event.

16. Amendment of the Plan. The Board may at any time, and from time to time, amend or suspend this Plan or any portion thereof, except that (a) if the approval of any such amendment by the shareholders of the Company is required by Section 423 of the Code, such amendment shall not be effected without such approval, and (b) in no event may any amendment be made that would cause the Plan to fail to comply with Section 423 of the Code.

17. Insufficient Shares. If the total number of shares of Common Stock specified in elections to be purchased under any Offering plus the number of shares purchased under previous Offerings under this Plan exceeds the maximum number of shares issuable under this Plan, the Board or the Committee will allot the shares then available on a pro-rata basis.

18. Termination of the Plan. This Plan may be terminated at any time by the Board. Upon termination of this Plan all amounts in the accounts of participating employees shall be promptly refunded.

19. Governmental Regulations. The Company’s obligation to sell and deliver Common Stock under this Plan is subject to listing on a national stock exchange (to the extent the Common Stock is then so listed or quoted) and the approval of all governmental authorities required in connection with the authorization, issuance or sale of such stock.

20. Governing Law. The Plan shall be governed by Delaware law except to the extent that such law is preempted by federal law.

21. Issuance of Shares. Shares may be issued upon exercise of an Option from authorized but unissued Common Stock, from shares held in the treasury of the Company, or from any other proper source.

22. Notification upon Sale of Shares. Each employee agrees, by entering the Plan, to promptly give the Company notice of any disposition of shares purchased under the Plan where such disposition occurs within two years after the date of grant of the Option pursuant to which such shares were purchased.

23. Grants to Employees in Foreign Jurisdictions. The Company may, to comply with the laws of a foreign jurisdiction, grant Options to employees of the Company or a Designated Subsidiary who are citizens or residents of such foreign jurisdiction (without regard to whether they are also citizens of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) with terms that are less favorable (but not more favorable) than the terms of Options granted under the Plan to employees of the Company or a Designated Subsidiary who are resident in the United States. Notwithstanding the preceding provisions of this Plan, employees of the Company or a Designated Subsidiary who are citizens or residents of a foreign jurisdiction (without regard to whether they are also citizens of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from eligibility under the Plan if (a) the grant of an Option under the Plan to a citizen or resident of the foreign jurisdiction is prohibited under the laws of such jurisdiction or (b) compliance with the laws of the foreign jurisdiction would cause the Plan to violate the requirements of Section 423 of the Code. The Company may add one or more appendices to this Plan describing the operation of the Plan in those foreign jurisdictions in which employees are excluded from participation or granted less favorable Options.

24. Authorization of Sub-Plans. The Board may from time to time establish one or more sub-plans under the Plan with respect to one or more Designated Subsidiaries, provided that such sub-plan complies with Section 423 of the Code.

25. Withholding. If applicable tax laws impose a tax withholding obligation, each affected employee shall, no later than the date of the event creating the tax liability, make provision satisfactory to the Board for payment of any taxes required by law to be withheld in connection with any transaction related to Options granted to or shares acquired by such employee pursuant to the Plan. The Company may, to the extent permitted by law, deduct any such taxes from any payment of any kind otherwise due to an employee.

26. Effective Date and Approval of Stockholders. The Plan shall become effective on the date that the Plan is approved by the Company’ stockholders (the “Effective Date”).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company”) are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission, and include, in the opinion of the Company, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of results which may be expected for the full year. The December 31, 2019 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on March 4, 2020. SIGNIFICANT RISKS AND UNCERTAINTIES In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The Company’s condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that there was no material adverse impact on the Company’s first half 2020 results of operations. The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company's customers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, delays in obtaining signed customer contracts for awarded projects, supply chain disruptions and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, the extent to which the COVID-19 pandemic may impact the Company's financial condition, liquidity, or results of operations is uncertain. On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. The Company estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 , an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback additionally provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.

Leases

LEASESOn January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did not reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company has also elected the practical expedient to not separate lease components and non-lease components and will account for the leases as a single lease component for all classes of leases.

Commitments and Contingencies	Jun. 30, 2020
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES The Company from time to time issues letters of credit and performance bonds, with their third-party lenders, to provide collateral. The Company also has future lease commitments which do not yet meet the criteria of a ROU asset or ROU liability as of June 30, 2020, for certain business offices. These commitments total $1,225 as of June 30, 2020 and relate to payments through 2026. Legal Proceedings The Company is involved in a variety of claims and other legal proceedings generally incidental to its normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, the Company does not believe the ultimate resolution of any of these existing matters would have a material adverse effect on its financial condition or results of operations. Commitments as a Result of Acquisitions In August 2018, the Company completed an acquisition which provided for a revenue earn-out contingent upon the acquired business meeting certain cumulative revenue targets over five years from the acquisition date. The Company evaluated financial forecasts of the acquired business and concluded that the fair value of this earn-out was approximately $555, which was subsequently increased to $678 as of December 31, 2019 which remained consistent at June 30, 2020, and is recorded in the other liabilities on the condensed consolidated balance sheets. The contingent consideration will be paid annually, commencing in 2020, if any of the cumulative revenue targets are achieved. The fair value of the earn-out will be re-evaluated at each reporting period and adjustments will be recorded as needed. See Note 10 for additional information. In November 2018, the Company completed an acquisition of certain lease options, which provided for an earn-out if the lease option is exercised and if certain financial metrics are achieved. The Company evaluated the acquired lease options and concluded that the fair-value of this contingent liability was approximately $363, which was subsequently increased to $378 at December 31, 2019 which remained consistent at June 30, 2020, and is recorded in accrued expenses and other current liabilities and other liabilities on the condensed consolidated balance sheets. Payments will be made when milestones are achieved. The contingent liability will be re-evaluated at each reporting period and adjustments will be recorded as needed. In April 2020, the Company completed an acquisition which provided for a profit earn-out contingent upon the acquired project meeting certain financial return targets. The Company evaluated the financial forecasts of the acquired asset and concluded that fair value of the earn-out was $0 at completion of the acquisition which will be re-evaluated at each reporting period. The contingent consideration will be paid annually beginning in 2021, if the financial return targets are achieved.

Noncontrolling Interest [Abstract]
Non-controlling Interests and Equity	NON-CONTROLLING INTERESTS AND EQUITY Redeemable Non-controlling Interests The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the third quarter of 2015 has the right, beginning on the fifth anniversary of the final funding of the variable rate construction and term loans due 2023 and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund, which was formed in the third quarter of 2015, also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option. The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2017 has the right, beginning on the fifth anniversary of the final funding of the non-controlling interest holder and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2017 also includes a right, beginning on the sixth anniversary of the final funding and extending for one year, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option. The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the second quarter of 2018 has the right, beginning on the fifth anniversary of the investment fund’s final project being placed into service and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the second quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest holder to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option. The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2018 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2018 also includes a right, upon the expiration of the call option and extending for six months, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option. The Company’s wholly owned subsidiary with a membership interest in the investment fund formed in the fourth quarter of 2019 has the right, beginning on the fifth anniversary on the last projects placed in-service date and extending for six months, to elect to require the non-controlling interest holder to sell all of its membership units to the Company’s wholly owned subsidiary, a call option. The Company’s investment fund formed in the fourth quarter of 2019 also includes a right, beginning six months after the fifth anniversary of the final funding and extending for one year, for the non-controlling interest partner to elect to require the Company’s wholly owned subsidiary to purchase all of its membership interests in the fund, a put option. The purchase price for two of the investment funds investors’ interests under the call options is equal to the fair market value of such interest at the time the option is exercised. The purchase price for two of the investment funds investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 7% of the investors’ contributed capital balance at the time the option is exercisable. The purchase price for the remaining investment fund investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 5% of the investors’ contributed capital balance at the time the option is exercisable. The call options are exercisable beginning on the date that specified conditions are met for each respective fund. None of the call options are expected to become exercisable prior to 2021. The purchase price for two of the funds investors’ interests in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and a specified amount, ranging from $659 - $917. The purchase price for the two of the remaining funds investors’ interest in the investment funds under the put options is the sum of (i) the fair market value at the time the option is exercised, and (ii) the closing costs incurred by the investor in connection with the exercise of the put option. The purchase price for the remaining fund investors’ interest in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and the sum of (i) 5% of the investors’ contributed capital balance at the time the option is exercisable, and (ii) the fair market value of any unpaid tax law change losses incurred by the investor in connection with the exercise of the put option. The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund. The put options are not expected to become exercisable prior to 2022. Because the put options represents redemption features that are not solely within the control of the Company, the non-controlling interests in these funds are presented outside of permanent equity. Redeemable non-controlling interests are reported using the greater of their carrying value at each reporting date (which is impacted by attribution under the hypothetical liquidation at book value method) or their estimated redemption value in each reporting period. At both June 30, 2020 and December 31, 2019 redeemable non-controlling interests were reported at their carrying value totaling $36,303 and $31,616, respectively, as the carrying value at each reporting period was greater than the estimated redemption value.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Fair Value Measurement In August 2018, the FASB issued ASU 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements. Consolidations In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810), Targeted Improvements to Related Party Guidance for Variable Interest Entities, which aligns the evaluation of whether a decision maker's fee is a variable interest with the guidance in the primary beneficiary test by requiring the decision maker to consider an indirect interest in a VIE held by related party under common control on a proportionate basis. The new standard is effective interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company adopted this guidance as of January 1, 2020 and the adoption did not have an impact on the Company’s condensed consolidated financial statements. Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), and a subsequent amendment to the initial guidance, ASU 2018-19 Codification Improvements to Topic 326, Financial Instruments—Credit Losses (collectively, Topic 326). Topic 326 requires measurement and recognition of expected credit losses for financial assets held, which include, but are not limited to, trade and other receivables. The new standard is effective for fiscal years beginning after December 15, 2019, The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives, and Hedging, and Topic 825, Financial Instruments. The improvements to Topic 815, among other things, clarifies some areas around partial-term fair value hedges, interest rate risk, the amortization of fair value hedge basis adjustments and their disclosure, and some clarification of matters related to the transitioning to ASU 2017-12, which was adopted by the Company during the year ended December 31, 2018. The improvements to Topic 326 clarifies certain aspects surrounding accounting for credit losses in connection with the Company’s receivables. These include that the Company should include anticipated recoveries in its calculation of credit losses. For those that have already adopted ASU No. 2017-12, the new standard is effective the first annual period beginning after the issuance date of ASU No. 2019-04, or as of January 1, 2020 for the Company, with early adoption permitted. The Company adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on the Company’s condensed consolidated financial statements. Income Taxes In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for the Company for the fiscal year beginning after December 15, 2020. The Company is currently evaluating the impacts of the provisions of ASU 2019-12 on its condensed consolidated financial statements and disclosures. Others In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. Companies can apply the ASU immediately, however the guidance will only be available until December 31, 2022. The Company is currently evaluating the impact that adopting this new accounting standard will have on its condensed consolidated financial statements and related disclosures.
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated using the Company’s weighted-average outstanding common shares, including vested restricted shares. When the effects are not anti-dilutive, diluted earnings per share is calculated using the weighted-average outstanding common shares; the dilutive effect of convertible preferred stock, under the “if converted” method; and the treasury stock method with regard to warrants and stock options; all as determined under the treasury stock method.
