NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Basis of Presentation
The words "Company,” “we,” “us,” or “our” refer to Selective Insurance Group, Inc. (the "Parent") and its subsidiaries, except as expressly indicated or the context requires otherwise. We have prepared our interim unaudited consolidated financial statements (“Financial Statements”) in conformity with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. These require us to make estimates and assumptions that affect the reported financial statement balances and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany accounts and transactions between the Parent and its subsidiaries are eliminated in consolidation.

Our Financial Statements reflect all adjustments that, in our opinion, are normal, recurring, and necessary for a fair presentation of our results of operations and financial condition. Our Financial Statements cover the second quarters ended June 30, 2021 (“Second Quarter 2021”) and June 30, 2020 (“Second Quarter 2020”) and the six-month periods ended June 30, 2021 (“Six Months 2021”) and June 30, 2020 (“Six Months 2020”). Our Financial Statements do not include all information and disclosures required by GAAP and the SEC for audited annual financial statements. Because results of operations for any interim period are not necessarily indicative of results for a full year, our Financial Statements should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Annual Report”) filed with the SEC.

NOTE 2. Adoption of Accounting Pronouncements 
In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes - Simplifying the Accounting for Income Taxes (“ASU 2019-12”). Among other items, ASU 2019-12 simplifies the accounting treatment of tax law changes and year-to-date losses in interim periods. An entity generally recognizes the effects of a change in tax law in the period of enactment; however, there is an exception for tax laws with delayed effective dates. Under current guidance, an entity may not adjust its annual effective tax rate for a tax law change until the period in which the law is effective. ASU 2019-12 provides that all effects of a tax law change, including adjustment of the estimated annual effective tax rate, are recognized in the period of enactment.

For year-to-date losses in interim periods, an entity is required currently to estimate its annual effective tax rate for the full fiscal year at the end of each interim period and use that rate to calculate its income taxes on a year-to-date basis. When an interim period loss exceeds the anticipated loss for the year, the income tax benefit is limited to the amount that would be recognized if the year-to-date loss were the anticipated loss for the full year. ASU 2019-12 removes this limitation and an entity would compute its income tax benefit at each interim period based on its estimated annual effective tax rate.

We adopted this guidance on January 1, 2021, and it did not have a material impact to our financial condition, cash flows, or results of operations.

Pronouncements to be effective in the future
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”). ASU 2020-04 provides optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition away from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. Companies can elect to adopt ASU 2020-04 as of the beginning of the interim period that includes March 2020, or any date thereafter through December 31, 2022. We are currently evaluating the impact of this guidance on our financial condition and results of operations.

For information on our methodology and significant inputs used to measure expected credit losses, our accounting policy for recognizing write-offs of uncollectible amounts, and our treatment of accrued interest, refer to Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of our 2020 Annual Report. Accrued interest on AFS securities was $44.9 million as of June 30, 2021, and $43.8 million as of December 31, 2020. We did not record any write-offs during 2021 or 2020.

We do not currently intend to sell any of the securities in the tables above, nor will we be required to sell any of these securities. The decrease in gross unrealized losses during Six Months 2021 was driven by an increase in longer-dated benchmark United States Treasury rates, partially offset by the tightening of credit spreads. Considering these factors and our review of these securities under our credit loss policy as described in Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of our 2020 Annual Report, we have concluded that no allowance for credit loss is required on these balances. This conclusion reflects our current judgment as to the financial position and future prospects of the entity that issued the investment security and underlying collateral.

1The maximum exposure to loss includes both the carry value of these investments and the related remaining commitments. In addition, tax credits that have been previously recognized in Other securities are subject to the risk of recapture, which we do not consider significant.

We are contractually committed to make additional investments up to the remaining commitments stated above, but we do not have a material future obligation to fund losses or debts on behalf of these investments. We have not provided any non-contractual financial support at any time during 2021 or 2020.

The following table shows gross summarized financial information for our other investments portfolio, including the portion we do not own. The majority of these investments are carried under the equity method of accounting and report results to us on a one-quarter lag. The following table provides (i) the gross summarized financial statement information for these investments for the three and six-months ended March 31, and (ii) the portion of these results that are included in our Second Quarter and Six Months results:

(e) Certain Insurance Subsidiaries, as members of the Federal Home Loan Bank of Indianapolis ("FHLBI") and the Federal Home Loan Bank of New York ("FHLBNY"), have pledged certain AFS fixed income securities as collateral. Additionally, to comply with insurance laws, certain Insurance Subsidiaries have deposited certain securities with various state and regulatory agencies at June 30, 2021. We retain all rights regarding all securities pledged as collateral. The following table summarizes the market value of these securities at June 30, 2021:

The increase in net investment income earned in Second Quarter 2021 and Six Months 2021 compared to the prior year periods were driven by the alternative investments in our other investments portfolio. The results reflect the improvement in the equity markets in the three and six-month periods ending March 31, 2021, as our results on these holdings are recorded on a one-quarter lag.

The improvement in net realized and unrealized gains in Six Months 2021 as compared to Six Months 2020 was primarily driven by (i) unrealized gains on our equity securities compared to unrealized losses last year, which were driven by COVID-19-related market disruption, and (ii) lower intent-to-sell losses as we provided our investment managers significant trading flexibility last year given market conditions.

1Represents the impact of our adoption of ASU 2016-13, Financial Instruments - Credit Losses.

In Six Months 2020, we recognized an additional allowance for credit losses of $13.5 million, net of write-offs and recoveries. We based this increase on an evaluation of the recoverability of our premiums receivable in light of (i) the billing accommodations we announced during the first quarter of 2020 and (ii) the impact of certain state regulations that provided for deferral of payments without cancellation for a period up to 90 days and increased earned but uncollected premiums. The billing accommodations included individualized payment flexibility and suspending the effect of policy cancellations, late payment notices, and late or reinstatement fees. The heightened credit risk experienced in 2020 led us to increase the allowance for credit losses to $21.0 million in Second Quarter 2020. During Second Quarter 2021, we realized a portion of the anticipated write-offs, which reduced our allowance. The reduction was partially offset by the additional provision established on current-year premiums, which resulted in the ending allowance of $18.3 million.

Direct premiums written ("DPW") increased $120.1 million, or 14%, in Second Quarter 2021 compared to Second Quarter 2020. The increase included three percentage points from the COVID-19-related $19.7 million premium credit to our personal and commercial automobile policyholders in Second Quarter 2020. This premium credit to customers with in-force polices was equivalent to 15% of their April and May 2020 premiums.

Additionally, DPW increased $282.5 million, or 18%, in Six Months 2021 compared to Six Months 2020 resulted from (i) overall renewal pure price increases, (ii) new business growth, and (iii) strong retention. This increase also included seven percentage points from the $75.0 million return audit and endorsement premium accrual that was recorded in the first quarter of 2020 and the premium credit mentioned above. This accrual reflected lower exposure levels, which determine the premium we charge, attributable to the economic impacts of the COVID-19 pandemic and the anticipated decline in sales and payroll exposures on the general liability and workers compensation lines of business.

Ceded premiums written, ceded premiums earned, and ceded loss and loss expenses incurred related to our participation in the NFIP, to which we cede 100% of our flood premiums, losses, and loss expenses, were as follows:

Prior year reserve development in Six Months 2021 was favorable by $51.8 million, which included $52.0 million of casualty reserve development. The favorable casualty reserve development included $25.0 million in our general liability line of business, $20.0 million in our workers compensation line of business, and $7.0 million in our Excess and Surplus ("E&S") casualty lines of business.

Prior year reserve development in Six Months 2020 was favorable by $20.9 million, which included $25.0 million of casualty reserve development, partially offset by $4.1 million of unfavorable property reserve development. The favorable casualty reserve development included $25 million in our workers compensation line of business and $10 million in our general liability line of business, partially offset by $10.0 million of unfavorable reserve development in our commercial automobile line of business.

NOTE 9. Segment Information
We evaluate the results of our four reportable segments as follows:

Our Standard Commercial Lines, Standard Personal Lines, and E&S Lines are evaluated on before and after-tax underwriting results (net premiums earned, incurred loss and loss expense, policyholder dividends, policy acquisition costs, and other underwriting expenses), return on equity ("ROE") contribution, and combined ratios.
Our Investments segment is primarily evaluated on after-tax net investment income and its ROE contribution. After-tax net realized and unrealized gains and losses, which are not included in non-GAAP operating income, are also included in our Investment segment results.

In computing each segment's results, we do not make adjustments for interest expense or corporate expenses, nor do we allocate assets.

NOTE 10. Retirement Plans
The primary pension plan for our employees is the Retirement Income Plan for Selective Insurance Company of America (the “Pension Plan”). Selective Insurance Company of America ("SICA") also sponsors the Supplemental Excess Retirement Plan (the “Excess Plan”) and a life insurance benefit plan. All plans are closed to new entrants, and benefits ceased accruing under the Pension Plan and the Excess Plan after March 31, 2016. For more information about SICA's retirement plans, see Note 15. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of our 2020 Annual Report.

NOTE 12. Equity
On December 2, 2020, we announced that our Board of Directors authorized a $100 million share repurchase program, which has no set expiration or termination date. Our repurchase program does not obligate us to acquire any particular amount of our common stock, and the repurchase program may be suspended or discounted at any time at our discretion. The timing and amount of any share repurchases under the authorization will be determined by management at its discretion based on market conditions and other considerations. As of June 30, 2021, 52,781 shares were repurchased under the share repurchase program at a total cost of $3.4 million. These repurchases were all completed in the first quarter of 2021, and we did not repurchase any shares under our share repurchase program in Second Quarter 2021. We have $96.6 million of remaining capacity under our share repurchase program.

NOTE 13. Litigation
As of June 30, 2021, we do not believe we are involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

In the ordinary course of conducting business, we are parties in various legal actions. Most are claims litigation involving our Insurance Subsidiaries as (i) liability insurers defending or providing indemnity for third-party claims brought against our customers, (ii) insurers defending first-party coverage claims brought against them, or (iii) liability insurers seeking declaratory judgment on our insurance coverage obligations. We account for such activity through the establishment of unpaid loss and loss expense reserves. In ordinary course claims litigation, we expect that any potential ultimate liability, after consideration of provisions made for potential losses and costs of defense, will not be material to our consolidated financial condition, results of operations, or cash flows.

All of our commercial property and businessowners' policies require direct physical loss of or damage to property by a covered cause of loss. It also is our practice to include in, or attach to, all standard lines commercial property and businessowners' policies an exclusion that states that all loss or property damage caused by or resulting from any virus, bacterium, or other microorganism that induces or is capable of inducing physical distress, illness, or disease is not a covered cause of loss ("Virus Exclusion"). Whether COVID-19-related contamination, the existence of the COVID-19 pandemic, and the resulting
23

Table of Contents
COVID-19-related government shutdown orders cause physical loss of or damage to property is the subject of much public debate and first-party coverage litigation against some insurers, including us. The Virus Exclusion also is the subject of first-party coverage litigation against some insurers, including us. We cannot predict the outcome of litigation over these two coverage issues, including interpretation of provisions similar or identical to those in our insurance policies.

From time to time, our Insurance Subsidiaries also are named as defendants in other legal actions, some of which assert claims for substantial amounts. Plaintiffs may style these actions as putative class actions and seek judicial certification of a state or national class for allegations involving our business practices, such as improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies or improper reimbursement for automobile parts. Similarly, our Insurance Subsidiaries can be named in individual actions seeking extra-contractual damages, punitive damages, or penalties, often alleging bad faith in the handling of insurance claims. We believe that we have valid defenses to these allegations and we account for such activity through the establishment of unpaid loss and loss expense reserves. In these other legal actions, we expect that any potential ultimate liability, after consideration of provisions made for estimated losses, will not be material to our consolidated financial condition. Nonetheless, litigation outcomes are inherently unpredictable and, because the amounts sought in certain of these actions are large or indeterminate, it is possible that any adverse outcomes could have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.

NOTE 14. Subsequent Events
On July 21, 2021, we repaid our $25 million 1.61% borrowing from the FHLBNY.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Forward-Looking Statements
The terms "Company," "we," "us," and "our" refer to Selective Insurance Group, Inc. (the "Parent"), and its subsidiaries, except as expressly indicated or the context otherwise requires. In this Quarterly Report on Form 10-Q, we discuss and make statements about our intentions, beliefs, current expectations, and projections for our future operations and performance. Such statements are “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. These forward-looking statements often are identified by words such as “anticipates,” “believes,” “expects,” “will,” “should,” and “intends” and their negatives. We caution prospective investors that forward-looking statements are not guarantees of future performance. Risks and uncertainties are inherent in our future performance. Factors that could cause actual results to differ materially from those indicated in forward-looking statements include, without limitation, those discussed in Item 1A. “Risk Factors.” in Part II. “Other Information” of this Form 10-Q. Our stated risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time to time. We can neither predict such new risk factors nor can we assess the impact, if any, such new risk factors may have on our businesses or the extent to which any factor or combination of factors may cause actual results to differ materially from those expressed or implied in any forward-looking statement. In light of these risks, uncertainties, and assumptions, the forward-looking events discussed in this report might not occur. We make forward-looking statements based on currently available information and assume no obligation, other than as may be required under the federal securities laws, to publicly update or revise any forward-looking statements for any reason.

Introduction
We classify our business into four reportable segments:

Standard Commercial Lines;
Standard Personal Lines;
E&S Lines; and
Investments.

For more details about these segments, refer to Note 9. "Segment Information" in Item 1. "Financial Statements." of this Form 10-Q and Note 12. "Segment Information" in Item 8. "Financial Statements and Supplementary Data." of our Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Annual Report").

We write our Standard Commercial and Standard Personal Lines products and services through nine of our insurance subsidiaries, some of which participate in the federal government's National Flood Insurance Program's ("NFIP") Write Your Own Program ("WYO"). We write our E&S products through another subsidiary, Mesa Underwriters Specialty Insurance Company, which provides us with a nationally-authorized non-admitted platform for customers who generally cannot obtain coverage in the standard marketplace. Collectively, we refer to our ten insurance subsidiaries as the "Insurance Subsidiaries."

Table of Contents
The following is Management’s Discussion and Analysis (“MD&A”) of the consolidated results of operations and financial condition, as well as known trends and uncertainties, that may have a material impact in future periods. Investors should read the MD&A in conjunction with Item 1. "Financial Statements." of this Form 10-Q and the consolidated financial statements in our 2020 Annual Report filed with the U.S. Securities and Exchange Commission.
In the MD&A, we will discuss and analyze the following:

Critical Accounting Policies and Estimates;
Financial Highlights of Results for the second quarters ended June 30, 2021 (“Second Quarter 2021”) and June 30, 2020 (“Second Quarter 2020”) and the six-month periods ended June 30, 2021 (“Six Months 2021”) and June 30, 2020 (“Six Months 2020”);
Results of Operations and Related Information by Segment;
Federal Income Taxes;
Financial Condition, Liquidity, and Capital Resources;
Ratings;
Off-Balance Sheet Arrangements; and
Contractual Obligations, Contingent Liabilities, and Commitments.

Critical Accounting Policies and Estimates
Our unaudited interim consolidated financial statements include amounts for which we have made informed estimates and judgments for transactions not yet completed. Such estimates and judgments affect the reported amounts in the consolidated financial statements. As outlined in our 2020 Annual Report, those estimates and judgments most critical to the preparation of the consolidated financial statements involved the following: (i) reserves for loss and loss expense; (ii) investment valuation and the allowance for credit losses on available-for-sale ("AFS") fixed income securities; (iii) reinsurance; (iv) allowance for credit losses on premiums receivable, and (v) the accrual for auditable premium. These estimates and judgments require the use of assumptions about matters that are highly uncertain, and therefore are subject to change as facts and circumstances develop. If different estimates and judgments had been applied, materially different amounts might have been reported in the financial statements.

We have made no material changes in the critical accounting policies disclosed on pages 37 through 46 of our 2020 Annual Report. There were no material changes to the following estimates in Second Quarter 2021: (i) reinsurance; and (ii) the allowance for credit losses on premiums receivable.

The following estimates materially changed in Second Quarter 2021:
Investment valuation and the allowance for credit losses on AFS fixed income securities - See Note 4. "Investments" and Note 5. "Fair Value Measurements" in Item 1. "Financial Statements." of this Form 10-Q;
Reserve for loss and loss expense - See Note 8. "Reserve for Loss and Loss Expense" in Item 1. "Financial Statements." of this Form 10-Q; and
Accrual for auditable premium - In the first quarter of 2020, we recorded a $75 million return audit and mid-term endorsement premium accrual in response to the COVID-19 pandemic and the anticipated decline in payroll and sales exposures on the workers compensation and general liability lines of business. The remaining accrual was $24.8 million as of December 31, 2020. During Six Months 2021, we applied premium adjustments for audits, fully exhausting this accrual as of June 30, 2021. Since April 2020, through active engagement among our underwriters, insureds, and distribution partners, we have established exposure levels to reflect our best estimate of how the current environment may impact our policies. As a result, we do not have material accruals for additional or return premium as of June 30, 2021.

2    Non-GAAP operating income is a measure comparable to net income available to common stockholders but excludes after-tax net realized and unrealized gains and losses on investments. Non-GAAP operating income is used as an important financial measure by us, analysts, and investors because the timing of realized investment gains and losses on sales of securities in any given period is largely discretionary. In addition, net realized and unrealized investment gains and losses on investments that are charged to earnings could distort the analysis of trends.

Reconciliations of net income available to common stockholders, net income available to common stockholders per diluted common share, and annualized ROE to non-GAAP operating income, non-GAAP operating income per diluted common share, and annualized non-GAAP operating ROE, respectively, are provided in the tables below:

Our Six Months 2021 annualized non-GAAP operating ROE of 16.4% is above our full-year 2021 target of 11%, and our Six Months 2020 annualized non-GAAP operating ROE of 6.7%. Non-GAAP operating income per diluted common share increased (i) $1.45 in Second Quarter 2021 compared to Second Quarter 2020, and (ii) $2.30 in Six Months 2021 compared to Six Months 2020.

The increase in non-GAAP operating income per diluted common share in Second Quarter and Six Months 2021 compared to Second Quarter and Six Months 2020 was primarily driven by:
Catastrophe losses (lower by $0.98 in Second Quarter 2021 and $1.05 in Six Months 2021) driven by industry-wide U.S. catastrophe loss activity in 2020 that significantly exceeded the 10-year historical median;
Investment income (higher by $0.64 in Second Quarter 2021 and $0.82 in Six Months 2021) driven by our other investments portfolio, which principally includes alternative investments; and
Favorable prior year casualty reserve development (higher by $0.31 in Six Months 2021) attributable to accident years 2018 and prior.

Outlook
We entered 2021 in the strongest financial position in our Company's long history, well positioned to continue generating disciplined and profitable growth. During 2021, we continued to focus on several areas to position us for ongoing success:

Delivering on our strategy for continued disciplined growth by (i) continuing to expand our Standard Commercial Lines market share by increasing our share of wallet with existing agents and strategically appointing new agents, (ii) investing in geographic expansion, with a plan to add Vermont, Alabama, and Idaho, subject to regulatory approval, in the near-term, and other states over time, (iii) increasing customer retention by delivering a superior omnichannel experience and offering value-added technologies and services, and (iv) shifting our focus towards the mass affluent market within our Standard Personal Lines segment, which is a customer base that derives greater value from coverage and service.
Continuing to achieve written renewal pure price increases that meet or exceed expected loss trend, while delivering on our strategy for continued disciplined growth. We achieved overall renewal pure price increases of 5.1% in Second Quarter 2021 and 5.2% in Six Months 2021, which we believe is above our expected loss trend.
Continuing to build on a culture centered on the values of diversity, equity, and inclusion that fosters innovation and idea generation and developing a group of specially trained leaders who can guide us successfully into the future.

For more details about our major areas of strategic focus, refer to the "Outlook" section in "Financial Highlights of Results for Years Ended December 31, 2020, 2019, and 2018" within Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of our 2020 Annual Report.

For 2021, we revised our full-year guidance as follows:

A GAAP combined ratio, excluding catastrophe losses, of 89% (prior guidance 90%) that assumes no additional prior-year casualty reserve development;
Catastrophe losses of 4.0 points on the combined ratio;
After-tax net investment income of $220 million (prior guidance $195 million) that includes $55 million (prior guidance $31 million) in after-tax net investment income from our alternative investments;
27

Table of Contents
An overall effective tax rate of approximately 20.5%, that includes an effective tax rate of 19.0% for net investment income and 21% for all other items; and
Weighted average shares of 60.5 million on a diluted basis.

The NPW growth in Second Quarter and Six Months 2021 compared to the prior year periods reflects our strong relationships with best-in-class distribution partners, sophisticated underwriting and pricing tools, and excellent customer servicing capabilities. This solid growth included (i) overall renewal pure price increases, and (ii) new business growth, as shown in the following table:

In Second Quarter 2021, NPW growth was impacted by three points from the COVID-19-related premium credits to our personal and commercial automobile customers, which reduced NPW by $19.7 million in the prior-year period. The NPW growth in Six Months 2021 was further impacted by the COVID-19-related $75 million estimate of return audit and mid-term endorsement premium that reduced Six Months 2020 NPW, resulting in a total impact from COVID-19-related adjustments to NPW of approximately eight points in Six Months 2021.

Underwriting Expenses
The underwriting expense ratio decreased 1.6 points in Second Quarter 2021 compared to Second Quarter 2020 and 2.3 points in Six Months 2021 compared to Six Months 2020. The underwriting expense ratios in Second Quarter and Six Months 2020 were elevated by 2.2 points and 2.1 points, respectively, for COVID-19-related items. The decrease in the underwriting expense ratios in Second Quarter and Six Months 2021 reflect the absence of these COVID-19-related impacts, partially offset by an increase in profit-based compensation to our distribution partners and employees, which was 0.5 points higher in Second Quarter 2021 compared to Second Quarter 2020 and 0.3 points higher in Six Months 2021 compared to Six Months 2020.

The COVID-19-related items included in 2020 results were as follows: (i) lower net earned premiums from the estimate of return audit and mid-term endorsement premium recorded in the first quarter and premium credits given to our personal and commercial automobile customer during the second quarter; and (ii) increases of $3.0 million in the second quarter and $13.5 million in the first six months of last year to our allowance for credit losses on premiums receivable.

Additionally, Second Quarter 2021 NPW growth was impacted by three points from the COVID-19-related premium credits to our commercial automobile customers, which reduced NPW by $15.4 million in the prior-year period. The NPW growth in Six Months 2021 was further impacted by the COVID-19-related $75 million estimate of return audit and mid-term endorsement premium that reduced Six Months 2020 NPW, resulting in a total impact from COVID-19-related adjustments to NPW of approximately nine points in Six Months 2021.

The loss and loss expense ratio decreased 6.4 points in Second Quarter 2021 and 5.9 points in Six Months 2021 compared to the same prior-year periods, driven by the following:

Catastrophe losses in Second Quarter and Six Months 2021 were lower than our 10-year Standard Commercial Lines average of 2.9 points, whereas Second Quarter and Six Months 2020 were significantly higher than this average, in part due to numerous events designated by the Insurance Services Office's Property Claims Services unit that impacted us, including two April 2020 storms ($43 million) and claims related to civil unrest ($20 million).

In addition, the current year loss and loss expense ratio was higher by 1.2 points in Second Quarter 2021 and 0.8 points in Six Months 2021 compared to the same prior-year periods, primarily driven by increases in frequencies in 2021, as last year experienced lower frequencies reflecting reductions in miles driven due to the COVID-19-related governmental directives

impacting our commercial automobile lines of business in 2020. This, in conjunction with lower non-catastrophe property losses in the prior year period, provided an offset to the $15.4 million premium credit to customers in 2020.

For quantitative information on the favorable prior year casualty reserve development by line of business, see the "Insurance Operations" section above, and for qualitative information about the significant drivers of this development, see the line of business discussions below.

The underwriting expense ratio decreased 1.7 points in Second Quarter 2021 compared to Second Quarter 2020 and 2.5 points in Six Months 2021 compared to Six Months 2020. The underwriting expense ratios in Second Quarter and Six Months 2020 were elevated by 2.5 points and 2.3 points, respectively, for COVID-19-related items, as further discussed in "Insurance Operations" above. The decrease in the underwriting expense ratios in Second Quarter and Six Months 2021 reflect the absence of these COVID-19-related impacts, partially offset by an increase in profit-based compensation to our distribution partners and employees, which was 0.5 points higher in both Second Quarter 2021 and Six Months 2021.

NPW grew 12% in Second Quarter 2021 and 27% in Six Months 2021 compared to the same prior year periods due to new business growth, renewal pure price increases, and strong retention. NPW in Six Months 2021 was also impacted by 15 points from the COVID-19-related $46 million estimate of return audit and mid-term endorsement premium recorded on this line in the first quarter of 2020.

The Second Quarter and Six Months 2020 reserve development was primarily attributable to favorable reserve development on loss severities in accident years 2016 and prior.

In addition to the items above, the combined ratios were impacted by a decrease in the underwriting expense ratio of 1.4 points in Second Quarter 2021 compared to Second Quarter 2020 and 2.3 points in Six Months 2021 compared to Six Months 2020, the drivers of which are consistent with the items discussed in the Standard Commercial Lines Segment above.

NPW growth benefited from renewal pure price increases and growth in direct new business, as shown in the table above. This growth also includes an in-force vehicle count increase of 7% as of June 30, 2021 compared to June 30, 2020. Additionally, NPW growth includes 11 points in Second Quarter 2021 and 5 points in Six Months 2021 due to the $15.4 million premium credit given to our commercial automobile customers as a result of the COVID-19 pandemic in Second Quarter 2020, as discussed in the Standard Commercial Lines discussion above.

In addition, the current year loss and loss expense ratio was higher by 1.6 points in Second Quarter 2021 and 0.6 points in Six Months 2021 compared to the same prior-year periods, primarily driven by increases in frequencies in 2021, as last year experienced lower frequencies reflecting reductions in miles driven due to the COVID-19-related governmental directives impacting this line of business in 2020. This, in conjunction with lower non-catastrophe property losses in the prior year period, provided an offset to the $15.4 million premium credit to customers in 2020.

The Second Quarter and Six Months 2020 prior year casualty reserve development was primarily attributable to unfavorable reserve development on loss severities in accident years 2016 through 2019, and higher than expected frequencies in accident year 2019.

In addition to the items above, the combined ratios were impacted by a decrease in the underwriting expense ratio of 4.3 points in Second Quarter 2021 compared to Second Quarter 2020 and 3.9 points in Six Months 2021 compared to Six Months 2020, the drivers of which are consistent with the items further discussed in the Standard Commercial Lines Segment above.

NPW increased 7% in Second Quarter 2021 and 37% in Six Months 2021 compared to the respective prior year periods due to increased direct new business and higher retention. Additionally, NPW growth in Six Months 2021 was impacted by 25 points due to the COVID-19-related $29 million estimate of return audit and mid-term endorsement premium recorded on this line in the first quarter of 2020.

The increase in the combined ratio in Second Quarter 2021 and Six Months 2021 compared to the same prior-year periods was driven by favorable prior year casualty reserve development, as follows:

NPW was flat in Second Quarter 2021 compared to Second Quarter 2020 and decreased 1% in Six Months 2021 compared to Six Months 2020, primarily driven by new business that was not sufficient to compensate for the policies lost at renewal due to the challenging competitive environment in the personal auto line of business. Offsetting this decrease was the impact of the COVID-19-related premium credits to our personal automobile customers, which reduced NPW by $4.3 million in the prior-year period, and added five points of growth in Second Quarter 2021 compared to Second Quarter 2020 and three points of growth in Six Months 2021 compared to Six Months 2020.

Ten events were designated as catastrophes that impacted Second Quarter 2021, with a severe thunderstorm, including wind and hail, in late June 2021 in our footprint states having the most significant impact on results. Six Months 2021 results were also impacted by a severe thunderstorm, accompanied by wind and hail, in March 2021, which affected our footprint states. Thirteen events impacted Second Quarter 2020, which included two severe storms occurring in April 2020, that impacted parts of the Mid-West and East Coast regions of the United States with damaging winds and tornadoes. Additionally, Six Months 2020 was affected by a tornado that impacted Tennessee in March 2020.

In addition, the current year loss and loss expense ratio was higher by 1.2 points in Second Quarter 2021 and 0.3 points in Six Months 2021 compared to the same prior-year periods, primarily driven by increases in frequencies in 2021, as last year experienced lower frequencies reflecting reductions in miles driven due to the COVID-19-related governmental directives impacting our personal automobile line of business in 2020. This, in conjunction with lower non-catastrophe property losses in the prior year period, provided an offset to the $4.3 million premium credit to customers in 2020.

The underwriting expense ratio decreased 0.9 points in Second Quarter 2021 compared to Second Quarter 2020 and 1.6 points in Six Months 2021 compared to Six Months 2020. The underwriting expense ratios in Second Quarter and Six Months 2020 were elevated by 2.1 points and 2.2 points, respectively, for COVID-19-related items, as further discussed in "Insurance Operations" above. The decrease in the underwriting expense ratios in Second Quarter and Six Months 2021 reflect the absence of these COVID-19-related impacts, partially offset by an increase in profit-based compensation to our employees, which was 0.8 points in Second Quarter 2021 and 0.6 points in Six Months 2021.

The increase in catastrophe losses in Six Months 2021 compared to Six Months 2020 was primarily due to a series of large storms that significantly impacted Texas and other southern and central states. Non-catastrophe property loss and loss expenses were also elevated in both periods due to an increase in severity of a few commercial property losses from fires.

The favorable prior year casualty reserve development in Second Quarter and Six Months 2021 was primarily attributable to lower loss severities in accident years 2016 through 2018. There was no prior year casualty reserve development in Second Quarter and Six Months 2020.

The underwriting expense ratio decreased 2.5 points in Second Quarter 2021 and 3.1 points in Six Months 2021 compared to the respective prior year periods, primarily due to a decrease in labor and travel expenses of 1.6 points in Second Quarter 2021 and 1.7 points in Six Months 2021 compared to the same prior-year periods. In addition, the underwriting expense ratios in Second Quarter and Six Months 2020 were elevated by 0.4 points and 1.0 point, respectively, for COVID-19-related increases in our allowance for credit losses on premiums receivable as further discussed in "Insurance Operations" above.

Reinsurance
We successfully completed negotiations of our July 1, 2021 excess of loss treaties, which provide coverage for our Standard Commercial Lines, Standard Personal Lines, and E&S Lines. The Casualty Excess of Loss (“Casualty Treaty”) was renewed with the same structure as the expiring treaty. The treaty year ceded deposit premium increased $9.5 million, or 16%, reflecting a slight rate increase coupled with an increase in projected subject earned premium.

The Property Excess of Loss (“Property Treaty”) was renewed with an increase in the retention on the first layer from $2.0 million to $3.0 million, thereby decreasing the coverage in excess of retention to $7.0 million from $8.0 million. The subsequent layers remained the same. The treaty year deposit premium increased $0.5 million, or 1%, reflecting a risk-adjusted rate increase along with an increase in projected subject premium offset with the premium reduction benefit of the aforementioned first layer retention increase.

For non-NBCR losses, the treaty distinguishes between acts committed on behalf of foreign persons or foreign interests ("Foreign Terrorism") and those that are not. The treaty provides annual aggregate limits for Foreign Terrorism (other than NBCR) acts of $21 million for the first layer, $60 million for the second layer, and $40 million for the third layer. Non-foreign terrorism losses (other than NBCR) are covered to the same extent as non-terrorism losses.
Casualty Excess of Loss (covers all insurance operations)
There are six layers covering 100% of $88 million in excess of $2 million. Losses other than terrorism losses are subject to the following:

- $3 million in excess of $2 million layer provides 33
      reinstatements, $102 million annual aggregate limit;
- $7 million in excess of $5 million layer provides six
      reinstatements, $49 million annual aggregate limit;

Investments
The primary objective of the investment portfolio is to maximize after-tax net investment income and its overall total return while maintaining a high credit quality core fixed income securities portfolio and managing our duration risk profile. The effective duration of our fixed income and short-term investments was 3.9 years as of June 30, 2021, compared to the Insurance Subsidiaries' liability duration of 3.7 years at December 31, 2020. The effective duration is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. We maintain a well-diversified portfolio across sectors, with credit quality and maturities that provide ample liquidity. Purchases and sales are intended to maximize investment returns in the current market environment while balancing capital preservation.

Our fixed income and short-term investments represented 91% of our invested assets at June 30, 2021, and 92% at December 31, 2020. At June 30, 2021, these investments had a weighted average credit rating of "A+" compared to “AA-” as of December 31, 2020, with a 96% allocation to investment grade holdings at both periods. The decline in the weighted average credit rating reflects a meaningful reduction in our sector allocation to agency residential mortgage-backed securities over the past year as lower interest rates accelerated prepayments as we had expected. Given the very low reinvestment rates for this asset class, we have reallocated these non-sale disposal cash flows into other high-quality fixed income sectors, including corporate securities and other asset-backed security classes that do not carry a "AAA" rating, but in our view currently offer a better risk and reward trade-off.

Invested assets increased as of June 30, 2021, compared to December 31, 2020, reflecting operating cash flows during Six Months 2021 of $292.5 million, that were 18% of NPW, partially offset by a decrease in pre-tax unrealized gains of $46.8 million. The decrease in gross unrealized gains during Six Months 2021 was driven by an increase in longer-dated benchmark United States Treasury rates, partially offset by tightening credit spreads.

The increase in after-tax net investment income in Second Quarter and Six Months 2021 compared to Second Quarter and Six Months 2020 was driven by higher returns on alternative investments in our other investment portfolio of $29.9 million in Second Quarter 2021 and $50.1 million in Six Months 2021, compared to losses of $16.0 million and $9.7 million in the same prior-year periods, respectively. These returns are recorded on a one-quarter lag, and reflect the strong capital market performance in the three and six-month periods ending March 31, 2021.

Realized and Unrealized Gains and Losses
Our general investment philosophy for sales of securities is to (i) reduce our exposure to securities and sectors that we have evaluated and determined have deteriorated economic fundamentals, or (ii) determine appropriate timing for an opportunistic trade for other securities or sectors with better economic-return characteristics. Net realized and unrealized gains and losses for the indicated periods were as follows:

The improvement in net realized and unrealized gains in Six Months 2021 compared to Six Months 2020 was primarily driven by (i) unrealized gains on our equity securities this year compared to unrealized losses last year, which were driven by COVID-19-related market disruption last year, and (ii) lower intent-to-sell losses this year as we provided our investment managers significant trading flexibility last year given market conditions.

Financial Condition, Liquidity, and Capital Resources
Capital resources and liquidity reflect our ability to generate cash flows from business operations, borrow funds at competitive rates, and raise new capital to meet operating and growth needs.

Liquidity
We manage liquidity by focusing on generating sufficient cash flows to meet the short-term and long-term cash requirements of our business operations.

Sources of Liquidity
Sources of cash for the Parent historically have consisted of dividends from the Insurance Subsidiaries, the investment portfolio held by the Parent, borrowings under third-party lines of credit, loan agreements with certain Insurance Subsidiaries, and the issuance of equity and debt securities. We continue to monitor these sources, giving consideration to our long-term liquidity and capital preservation strategies.

The Parent's investment portfolio provides liquidity through (i) short-term investments that are generally maintained in “AAA” rated money market funds approved by the National Association of Insurance Commissioners, (ii) high-quality, highly liquid government and corporate fixed income securities; (iii) equity securities, and (iv) a cash balance. In the aggregate, Parent cash and total investments amounted to $505 million at June 30, 2021 and $490 million at December 31, 2020.

The Parent's liquidity may fluctuate based on various factors, including the amount and availability of dividends from our Insurance Subsidiaries, investment income, expenses, other Parent cash needs, such as dividends payable to shareholders, asset allocation investment decisions, and share repurchases. Our target for the Parent is to maintain liquidity matching at least twice its expected annual needs, which is currently estimated at $180 million.

Insurance Subsidiary Dividends
The Insurance Subsidiaries generate liquidity through insurance float, which is created by collecting premiums and earning investment income before claims are paid. The period of float can extend over many years. Our investment portfolio consists of maturity dates that continually provide a source of cash flow for claims payments in the ordinary course of business. As protection for the capital resources at the Insurance Subsidiaries, we purchase reinsurance coverage for any significantly large claims or catastrophes that may occur.

The Insurance Subsidiaries paid $70 million in total dividends to the Parent during Six Months 2021. As of December 31, 2020, our allowable ordinary maximum dividend was $241 million for 2021. All Insurance Subsidiary dividends to the Parent are (i) subject to the approval and/or review of its domiciliary state insurance regulator, and (ii) generally payable only from earned surplus reported in its statutory annual statements as of the preceding December 31. Although domiciliary state insurance regulators historically have approved dividends, there is no assurance they will approve future Insurance Subsidiary dividends.

New Jersey corporate law also limits the maximum amount of dividends the Parent can pay our shareholders if either (i) the Parent would be unable to pay its debts as they became due in the usual course of business, or (ii) the Parent’s total assets would be less than its total liabilities. The Parent’s ability to pay dividends to shareholders is also impacted by (i) covenants in its credit agreement (discussed below under "Line of Credit") that obligate it, among other things, to maintain a minimum consolidated net worth and a maximum ratio of consolidated debt to total capitalization, and (ii) the terms of our preferred stock that prohibit dividends to be declared or paid on our common stock if dividends are not declared and paid, or made payable, on all outstanding preferred stock for the latest completed dividend period.

For additional information regarding dividend restrictions and financial covenants, where applicable, see Note 11. "Indebtedness", Note 17. "Preferred Stock", and Note 22. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. “Financial Statements and Supplementary Data.” of our 2020 Annual Report.

Line of Credit
On December 20, 2019, the Parent entered into a Credit Agreement with the lenders named therein (the “Lenders”) and the Bank of Montreal, Chicago Branch, as Administrative Agent ("Line of Credit"). Under the Line of Credit, the Lenders have agreed to provide the Parent with a $50 million revolving credit facility that can be increased to $125 million with the Lenders'
39

Table of Contents
consent. The Line of Credit will mature on December 20, 2022, and has a variable interest rate based on, among other factors, the Parent’s debt ratings.

For additional information regarding the Line of Credit and corresponding representations, warranties, and covenants, refer to Note 11. "Indebtedness" in Item 8. "Financial Statements and Supplementary Data." of our 2020 Annual Report. We met all covenants under our Line of Credit as of June 30, 2021.

Several Insurance Subsidiaries are members of Federal Home Loan Bank branches, as shown in the following table. Membership requires the ownership of branch stock and includes the right to borrow and gain access to liquidity. All FHLBI and FHLBNY borrowings are required to be secured by investments pledged as collateral. For additional information regarding collateral outstanding, refer to Note 4. "Investments" in Item 1. "Financial Statements." of this Form 10-Q:
BranchInsurance Subsidiary Member
FHLBI
Selective Insurance Company of South Carolina ("SICSC")1
Selective Insurance Company of the Southeast ("SICSE")1
FHLBNYSelective Insurance Company of America ("SICA")
Selective Insurance Company of New York ("SICNY")
1These subsidiaries are jointly referred to as the "Indiana Subsidiaries" as they are domiciled in Indiana.

The Line of Credit permits aggregate borrowings from the FHLBI and the FHLBNY up to 10% of the respective member company’s admitted assets for the previous year. Additionally, as SICNY is domiciled in New York, its FHLBNY borrowings are limited by New York insurance regulations to the lower of 5% of admitted assets for the most recently completed fiscal quarter, or 10% of admitted assets for the previous year-end. As of June 30, 2021, we had remaining capacity of $339 million for Federal Home Loan Bank borrowings, with a $12.2 million additional stock purchase requirement to allow the member companies to borrow their full remaining capacity amounts.

Short-term Borrowings
We did not make any short-term borrowings during Six Months 2021.

Intercompany Loan Agreements
The Parent has lending agreements with the Indiana Subsidiaries approved by the Indiana Department of Insurance, that provide it additional liquidity. Similar to the Line of Credit, these lending agreements limit the Parent's borrowings from the Indiana Subsidiaries to 10% of the admitted assets of the respective Indiana Subsidiary. The outstanding balance on these intercompany loans was $40.0 million as of both June 30, 2021 and December 31, 2020. The remaining capacity under these intercompany loan agreements was $97.1 million as of both June 30, 2021, and December 31, 2020.

Capital Market Activities
The Parent had no private or public issuances of stock during Six Months 2021. In the fourth quarter of 2020, we enhanced our capital structure flexibility at the Parent by issuing $200 million of 4.60% non-cumulative perpetual preferred stock. Net proceeds after issuance costs were approximately $195 million. The Parent is using these proceeds for general corporate purposes, which may include the repurchase of common stock under a $100 million share repurchase program authorized by our Board in conjunction with the preferred stock offering. During Six Months 2021, we repurchased 52,781 shares of our common stock under this authorization at a cost of approximately $3.4 million, with a $64.49 average price per share, with all share repurchases made in the first quarter of 2021. We have $96.6 million of remaining capacity under our share repurchase program.

Uses of Liquidity
The Parent's liquidity generated from the sources discussed above is used, among other things, to pay dividends to our shareholders. Dividends on shares of the Parent's common and preferred stock are declared and paid at the discretion of the Board of Directors based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors. On July 28, 2021, our Board of Directors declared:

A cash dividend of $0.25 per common share that is payable September 1, 2021 to holders of record as of August 13, 2021; and
A cash dividend of $287.50 per share on our 4.60% Non-Cumulative Preferred Stock, Series B (equivalent to $0.28750 per depository share) that is payable on September 15, 2021 to holders of record as of August 31, 2021.

Our ability to meet our interest and principal repayment obligations on our debt, as well as our ability to continue to pay dividends to our stockholders, is dependent on (i) liquidity at the Parent, (ii) the ability of the Insurance Subsidiaries to pay
40

Table of Contents
dividends, if necessary, and/or (iii) the availability of other sources of liquidity to the Parent. On July 21, 2021, we repaid one of our $25 million borrowings from the FHLBNY. This repayment increased our remaining capacity to $364 million, from $339 million, for Federal Home Loan Bank borrowings, as well as the related additional stock purchase requirement to $13.3 million, from $12.2 million, for the member companies to borrow their full remaining capacity amounts. The following summarizes our upcoming principal payments due:

$25 million to FHLBNY on August 16, 2021; and
$60 million to FHLBI on December 16, 2026.

Restrictions on the ability of the Insurance Subsidiaries to declare and pay dividends, without alternative liquidity options, could materially affect our ability to service debt and pay dividends on common and preferred stock. We currently expect to repay the $25 million FHLBNY borrowing in full on August 16, 2021 from available Insurance Subsidiaries liquid assets.

Capital Resources
Capital resources ensure we can pay policyholder claims, furnish the financial strength to support the business of underwriting insurance risks, and facilitate continued business growth. At June 30, 2021, we had GAAP stockholders' equity of $2.9 billion and statutory surplus of $2.3 billion. With total debt of $550.9 million at June 30, 2021, our debt-to-capital ratio was 16%. For additional information on our statutory surplus, see Note 22. "Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds" in Item 8. "Financial Statements and Supplementary Data." of our 2020 Annual Report.

Our cash requirements include, without limitation, principal and interest payments on various notes payable, dividends to stockholders, payment of claims, payment of commitments under limited partnership agreements, capital expenditures, and other operating expenses, including commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes. For further details regarding our cash requirements, refer to the section below entitled, “Contractual Obligations, Contingent Liabilities, and Commitments.”

We continually monitor our cash requirements and the amount of capital resources we maintain at the holding company and operating subsidiary levels. As part of our long-term capital strategy, we strive to maintain capital metrics that support our targeted financial strength relative to the macroeconomic environment. Based on our analysis and market conditions, we may take a variety of actions, including, without limitation, contributing capital to the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing existing debt, repurchasing shares of the Parent’s common stock, and increasing common stockholders’ dividends.

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders, while enhancing our financial strength and underwriting capacity. We have an attractive book of business and solid capital base, positioning us well to take advantage of market opportunities that may arise.

Book value per common share increased to $44.78 as of June 30, 2021, from $42.38 as of December 31, 2020, driven by $3.74 in net income per share, and partially offset by $0.86 of lower unrealized gains on our fixed income securities portfolio and $0.50 in dividends to our common shareholders.

Ratings
Our ratings remain the same as reported in our "Overview" section of Item 1. "Business." of our 2020 Annual Report and are as follows:
NRSROFinancial Strength RatingOutlook
AM Best CompanyAPositive
Moody's Investors Services ("Moody's")A2Stable

Standard & Poor's Global RatingsAStable

On April 2, 2021, Fitch reaffirmed our "A+" rating with a "stable" outlook. In taking this rating action, Fitch cited our strong capitalization, financial performance, stable underwriting results, and return metrics that have remained favorable compared to peers.

On May 6, 2021, Moody’s reaffirmed our "A2" rating with a "stable" outlook. In taking this action, Moody’s cited our (i) strong underwriting profitability, financial leverage and coverage metrics, (ii) conservative investment portfolio, and (iii) strong regional franchise presence and established independent agency support.

Off-Balance Sheet Arrangements
At June 30, 2021, and December 31, 2020, we had no material relationships with unconsolidated entities or financial partnerships, such as structured finance or special purpose entities, established to facilitate off-balance sheet arrangements or other contractually narrow or limited purposes. Consequently, we are not exposed to any material financing, liquidity, market, or credit risk related to off-balance sheet arrangements.

Contractual Obligations, Contingent Liabilities, and Commitments
Our future cash payments associated with (i) loss and loss expense reserves, (ii) contractual obligations pursuant to operating and financing leases for office space and equipment, and (iii) notes payable have not materially changed since December 31, 2020. At June 30, 2021, we had certain contractual obligations that may require us to invest additional amounts in our investment portfolio as follows:
($ in millions)Amount of ObligationYear of Expiration of Obligation
Alternative and other investments$222.9 2036

There is no certainty that any such additional investment will be required. We expect to have the capacity to repay and/or refinance these obligations as they come due.

We have issued no material guarantees on behalf of others and have no trading activities involving non-exchange traded contracts accounted for at fair value. For additional details on transactions with related parties, see Note 18. "Related Party Transactions" in Item 8. "Financial Statements and Supplementary Data." of our 2020 Annual Report.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in the information about market risk set forth in our 2020 Annual Report. While not reflective of a material shift in the overall risk/return characteristics of our fixed income and short-term investments, the aggregate weighted average credit rating of these portfolios decreased to "A+" as of June 30, 2021, from “AA-” as of December 31, 2020. The decline in the weighted average credit rating reflects a meaningful reduction in our sector allocation to agency residential mortgage-backed securities over the past year as lower interest rates accelerated prepayments, as we had expected. Given the very low reinvestment rates for this asset class, we have reallocated these non-sale disposal cash flows into other high-quality fixed income sectors, including corporate securities and other asset-backed security classes that do not carry a "AAA" rating, but in our view currently offer a better risk and reward trade-off.

ITEM 4. CONTROLS AND PROCEDURES.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this report. In performing this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control Integrated Framework ("COSO Framework") in 2013. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures as of the end of such period are (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act, and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is appropriately accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions about required disclosure. No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during Second Quarter 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

Incidental to our insurance operations, we are engaged in ordinary routine legal proceedings that, because litigation outcomes are inherently unpredictable, could have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods. For additional information regarding our legal risks, refer to Note 13. "Litigation" in Item 1. "Financial Statements." of this Form 10-Q and Item 1A. “Risk Factors.” below in Part II. “Other Information.” As of June 30, 2021, we have no material pending legal proceedings that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

ITEM 1A. RISK FACTORS.

Certain risk factors can significantly impact our business, liquidity, capital resources, results of operations, financial condition, and debt ratings. These risk factors might affect, alter, or change actions we might take executing our long-term capital strategy. Examples include, without limitation, contributing capital to any or all of the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing our existing debt and/or equity securities, or increasing or decreasing stockholders' dividends. We operate in a continually changing business environment and new risk factors emerge from time to time. Consequently, we can neither predict such new risk factors nor assess the potential future impact, if any, they might have on our business. Except as discussed below,there have been no material changes from the risk factors disclosed in Item 1A. “Risk Factors.” in our 2020 Annual Report.

During Second Quarter 2021, the risk of broad economic inflation has emerged as a heightened risk relative to the risk factor discussed in our 2020 Annual Report. Inflation levels accelerated in Second Quarter 2021 with the overall consumer price index ("CPI"), the Core CPI, and the Producer Price Index all showing elevated levels compared to last year. As discussed in more detail in our 2020 Annual Report, inflation has significant potential impacts to our claims severity across multiple lines of business and could also cause higher levels of reserve development. Additionally, if heightened levels of economic inflation are tied to higher interest rate yields on fixed income securities, it could increase unrealized losses on our fixed income securities and lower total returns from our other invested assets.

Our repurchase program does not obligate us to acquire any particular amount of our common stock, and the repurchase program may be suspended or discontinued at any time at our discretion. The timing and amount of any share repurchases under the authorization will be determined by management at its discretion and based on market conditions and other considerations.
