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 (i) United States ("U.S.") generally accepted accounting principles (“GAAP”), and (ii) the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. These require management 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 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 first quarters ended March 31, 2024 (“First Quarter 2024”) and March 31, 2023 (“First Quarter 2023”). Our Financial Statements do not include all information and disclosures required by GAAP and the SEC for audited annual financial statements. Because interim period results of operations are not necessarily indicative of full-year results, our Financial Statements should be read in conjunction with the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Annual Report”) filed with the SEC.

NOTE 2. Adoption of Accounting Pronouncements

In June 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). ASU 2022-03 clarifies that a contractual sales restriction on an equity security is not considered when determining the security's fair value. This ASU was issued to eliminate diversity in practice by clarifying that contractual arrangements restricting an entity's ability to sell the security for a certain period of time is a characteristic of the reporting entity and should not be contemplated when determining the security's fair value. ASU 2022-03 requires new disclosures that provide investors with information about the restriction, including the nature and remaining duration of the restriction. The ASU is effective for annual periods beginning after December 15, 2023, including interim periods within those annual periods. We adopted this guidance on January 1, 2024 and it did not have a material impact to our financial condition, results of operations, or disclosures.

In March 2023, the FASB issued ASU 2023-02, Investments — Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method ("ASU 2023-02"). This ASU allows companies to elect to account for qualifying tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Companies were previously permitted to apply the proportional amortization method only to qualifying tax equity investments in low income housing tax credit structures. ASU 2023-02 extends the application of the proportional amortization method to qualifying tax equity investments that generate tax credits through other programs. It also requires new disclosures that provide a better understanding of the nature of the tax equity investments and the effect the tax equity investments and related income tax credits and other income tax benefits have on a company's financial position and results of operations. The ASU is effective for annual periods beginning after December 15, 2023, including interim periods within those fiscal years. We adopted ASU 2023-02 on January 1, 2024 and it did not have a material impact to our financial condition, results of operations, or disclosures.

Pronouncements to be effective in the future

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 amends disclosure requirements for segment reporting by modifying and adding disclosure requirements. The additional disclosure requirements include the following on both an interim and annual basis: (i) significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"); (ii) amounts for "other segment items" by reportable segment and a description of its composition; and (iii) the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. In addition, ASU 2023-07 requires all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280, Segment Reporting, to now be disclosed in interim periods. ASU 2023-07 is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As it only requires additional disclosure, ASU 2023-07 will not have an impact on our financial condition or results of operations.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 amends disclosure requirements to provide greater transparency on income taxes. The following additional disclosures are required annually: (i) specific required categories in the rate reconciliation, (ii) additional information for reconciling items

Table of Contents

that meet a quantitative threshold, (iii) the amount of income taxes paid disaggregated by jurisdiction, and (iv) income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Amendments can be applied on a prospective basis; however, retrospective application is permitted. Early adoption is permitted. As it only requires additional disclosure, ASU 2023-09 will not have an impact on our financial condition or results of operations.

We currently do not intend to sell any of the securities summarized in the tables above, nor do we believe we will be required to sell any of them. 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 2023 Annual Report, we have concluded that no additional allowance for credit loss is required on these balances beyond the allowance for credit loss recorded as of March 31, 2024. This conclusion reflects our current judgment about the financial position and future prospects of the entities that issued the investment security and underlying collateral.

(c) AFS and held-to-maturity ("HTM") fixed income securities at March 31, 2024, by contractual maturity are shown below. The maturities of RMBS, CMBS, CLO and other ABS securities were calculated using each security's estimated average life. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

1Other is comprised of broker quotes or other third-party pricing for which there is a lack of transparency into the inputs used to develop the valuations. The quantitative details of these unobservable inputs are neither provided to us, nor reasonably available to us, and therefore are not included in the tables above.

For the securities in the tables above valued using a discounted cash flow analysis, we apply an illiquidity spread in our determination of fair value. An increase in this assumption would result in a lower fair value measurement.

million in our general liability line of business, primarily driven by increased severities in accident years 2020 through 2023, partially offset by (ii) $15.0 million of favorable casualty reserve development in our workers compensation line of business.

Additionally, in our Standard Personal Lines segment, we had unfavorable casualty reserve development of $5.0 million in our personal automobile line of business, offset by favorable development of $5.0 million in our homeowners line of business.

Prior year reserve development in First Quarter 2023 was favorable by $13.0 million, consisting of favorable casualty reserve development of $10.0 million in our workers compensation line of business and $5.0 million in our Excess and Surplus ("E&S") casualty lines of business, partially offset by $2.0 million of unfavorable casualty reserve development in our personal 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 (i) before and after-tax underwriting results (net premiums earned, incurred loss and loss expense, policyholder dividends, policy acquisition costs, and other underwriting expenses), (ii) their return on equity ("ROE") contribution, and (iii) their 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 are also included in our Investments segment results.

In computing each segment's results, we do not make adjustments for interest expense or corporate expenses. No segment has a separate investment portfolio or allocated assets.

The following summaries present revenues (net investment income and net realized and unrealized gains and losses on investments in the case of the Investments segment) and pre-tax income for the individual segments:

NOTE 13. Litigation

As of March 31, 2024, 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 ten insurance subsidiaries (collectively referred to as "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 by establishing unpaid loss and loss expense reserves. Considering potential losses and defense costs reserves, we expect that any potential ultimate liability for ordinary course claims litigation will not be material to our consolidated financial condition, results of operations, or cash flows.

All our commercial property and businessowners' policies require direct physical loss of or damage to property by a covered cause of loss. All our standard lines commercial property and businessowners' policies also include or attach an exclusion that states 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 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 is also the subject of first-party coverage litigation against some insurers, including us. To date, insurers (including us) have prevailed in the majority of these suits, with most decisions holding that COVID-19 does not cause physical loss of or damage to property and the Virus Exclusion is valid. Nonetheless, these two matters continue to be litigated in trial courts, are subject to review by state and federal appellate courts, and their ultimate outcome cannot be assured.

Table of Contents

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

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. Certain statements in this Quarterly Report on Form 10-Q, including information incorporated by reference, are “forward-looking statements” defined in the Private Securities Litigation Reform Act of 1995 (“PSLRA”). The PSLRA provides a forward-looking statement safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements discuss our intentions, beliefs, projections, estimations, or forecasts of future events and financial performance. They involve known and unknown risks, uncertainties, and other factors that may cause our or our industry's actual results, activity levels, or performance to materially differ from those in or implied by the forward-looking statements. In some cases, forward-looking statements include the words “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” “continue,” or comparable terms. Our forward-looking statements are only predictions; we cannot guarantee or assure that such expectations will prove correct. We undertake no obligation to publicly update or revise any forward-looking statements for any reason except as may be required by law.

We discuss the factors that could cause our actual results to differ materially from our projects, forecasts, or estimates in forward-looking statements in Item 1A. “Risk Factors.” in Part II. “Other Information” of this Form 10-Q. These risk factors may not be exhaustive. We operate in a constantly changing business environment, and new risk factors may emerge at any time. We can neither predict these new risk factors nor assess their impact, if any, on our businesses or the extent to which any factor or combination of factors may cause actual results to differ materially from any forward-looking statements. Given these risks, uncertainties, and assumptions, the forward-looking events we discuss in this report might not occur.

Introduction

We classify our business into four reportable segments:

•Standard Commercial Lines;

•Standard Personal Lines;

•Excess and Surplus 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, 2023 ("2023 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. We write our E&S products through another subsidiary, Mesa Underwriters Specialty Insurance Company, 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."

The following is Management’s Discussion and Analysis (“MD&A”) of our financial condition and consolidated results of operations, including an evaluation of the amounts and certainty of cash flows from operations and outside sources, 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 2023 Annual Report filed with the United States ("U.S.") Securities and Exchange Commission.

Table of Contents

In the MD&A, we will discuss and analyze the following:

•Critical Accounting Policies and Estimates;

•Financial Highlights of Results for the first quarters ended March 31, 2024 (“First Quarter 2024”) and March 31, 2023 (“First Quarter 2023”);

•Results of Operations and Related Information by Segment;

•Federal Income Taxes;

•Liquidity and Capital Resources; and

•Ratings.

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 2023 Annual Report, those estimates and judgments most critical to the preparation of the consolidated financial statements involved the following: (i) reserve for loss and loss expense; (ii) investment valuation and the allowance for credit losses on available-for-sale ("AFS") fixed income securities; and (iii) reinsurance. These estimates and judgments require our use of assumptions about highly uncertain matters, making them 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. For additional information regarding our critical accounting policies and estimates, refer to pages 39 through 47 of our 2023 Annual Report.

2Non-GAAP operating income, non-GAAP operating income per diluted common share, and non-GAAP operating ROE are measures comparable to net income available to common stockholders, net income available to common stockholders per diluted common share, and ROE, respectively, but exclude after-tax net realized and unrealized gains and losses on investments included in net income. Adjusted book value per common share is a measure comparable to book value per common share, but excludes total after-tax unrealized gains and losses on investments included in accumulated other comprehensive (loss) income. These non-GAAP measures are important financial measures used by us, analysts, and investors because the timing of realized and unrealized investment gains and losses on securities in any given period is largely discretionary. In addition, net realized and unrealized investment gains and losses on investments could distort the analysis of trends.

In First Quarter 2024, we generated an ROE of 11.5%, compared to 15.1% in First Quarter 2023. Our non-GAAP operating ROE of 11.7% was below our First Quarter 2023 non-GAAP operating ROE of 14.6% and slightly below our target of 12%. The non-GAAP operating ROE decrease in First Quarter 2024 compared to First Quarter 2023 was driven by a $15.9 million, or 3.0-point, reduction in after-tax underwriting income, primarily attributable to unfavorable prior year casualty reserve development, partially offset by an improved expense ratio and lower net catastrophe losses in First Quarter 2024. Unfavorable prior year casualty reserve development was $35.0 million in First Quarter 2024, compared to favorable prior year casualty reserve development of $13.0 million in First Quarter 2023. During First Quarter 2024, we recorded unfavorable prior year casualty reserve development of $50.0 million in our general liability line of business, primarily in accident years 2020 through 2023, resulting from elevated and uncertain loss trends driven primarily by social inflation. Despite planning for higher expected loss trends, claim emergence in First Quarter 2024 exceeded our expectations. Partially offsetting the $50.0 million

Outlook

We entered 2024 with a strong capital position and solid operational results, well-positioned to navigate the ongoing challenges of elevated economic and social inflation and financial market volatility. We continue to focus on delivering on our strategy for disciplined and profitable growth within our insurance operation segments by:

•Standard Commercial Lines

◦Achieving overall Standard Commercial Lines renewal pure price increases that reflect our current profitability and forward loss trend expectations;

◦Continuing to expand our Standard Commercial Lines market share by (i) increasing our share towards our 12% target of our agents' premiums, (ii) strategically appointing new agents, and (iii) maximizing new business growth in the small business market through the use of our enhanced small business platform; and

◦Expanding our geographic footprint. In April 2024, we added West Virginia and Maine to our footprint, now covering 32 states. Subject to regulatory approvals, we expect to add Nevada, Washington, and Oregon later this year, and Kansas, Montana, and Wyoming in 2025. Over time, we plan to expand our Standard Commercial Lines footprint into most of the contiguous U.S.

•E&S Lines

◦Achieving E&S Lines renewal pure price increases that reflect our current profitability and forward loss trend expectations; and

◦Continuing to invest in product expansion, risk evaluation, and operational efficiency for small and middle market E&S accounts.

•Standard Personal Lines

◦Taking aggressive actions to improve the profitability of our Standard Personal Lines segment by:

▪Prioritizing additional rate filings on a state-by-state basis and further refining our pricing factors. These filed rate increases began to take effect early in 2023, increasing in number and magnitude throughout the year, have continued into 2024, and are expected to continue throughout the year. We project our overall written renewal rate increase to be in excess of 20% for the full year.

▪Seeking to improve our homeowners line of business profitability through the introduction of new policy terms and conditions, including (i) coverage for older roofs based on depreciation schedules rather than replacement cost, and (ii) implementing mandatory wind/hail deductibles in states exposed to severe convective storms, where allowed by law; and

▪Continuing the migration of our Standard Personal Lines products and services towards customers in the mass affluent market, where we believe we can be more competitive with our strong coverage and servicing capabilities.

For 2024, we increased our expectation for the GAAP combined ratio reflecting unfavorable prior year casualty reserve development and current year loss cost increases in the first quarter, while maintaining other full-year expectations as follows:

•A GAAP combined ratio of 96.5%, up from prior guidance of 95.5%, including net catastrophe losses of 5.0 points. Our combined ratio estimate assumes no additional prior year casualty reserve development;

•After-tax net investment income of $360 million that includes $32 million of after-tax net investment income from our alternative investments;

•An overall effective tax rate of approximately 21.0%, which assumes an effective tax rate of 20.5% for net investment income and 21% for all other items; and

•Weighted average shares of 61.5 million on a fully diluted basis, which assumes no share repurchases we may make under our authorization.

Prior year casualty reserve development in First Quarter 2024 was unfavorable by $35.0 million, or 4.2 points, compared to $10.0 million, or 1.4 points, of favorable development in First Quarter 2023. Despite increasing our overall expected loss trend in recent years, paid loss severities emerged more significantly than expected in First Quarter 2024. As a result, we recorded $50.0 million unfavorable prior year casualty reserve development in our general liability line of business, primarily driven by increased severities in accident years 2020 through 2023. This unfavorable development was partially offset by favorable workers compensation development of $15.0 million.

In addition, the loss and loss expense ratio was impacted by an increase in current year casualty loss costs of 0.7 points in First Quarter 2024 compared to First Quarter 2023, primarily due to increased loss trend expectations in response to social inflationary impacts. Refer to the line of business sections below for qualitative discussion on the significant drivers of unfavorable prior year casualty reserve development and current year loss costs.

The underwriting expense ratio decreased 1.6 points in First Quarter 2024 compared to First Quarter 2023, primarily due to premium growth outpacing the growth in underwriting expenses in First Quarter 2024 compared to First Quarter 2023.

This line of business has experienced a long-term historical trend of meaningful severity increases, which have been partially offset by decreases in claim frequencies. The trend of lower frequencies has continued, while prior year severities have developed adversely, previously impacting the pre-pandemic period but now extending into the more recent accident years. We attribute the increased severities to elevated social inflation, which we see as an industry dynamic characterized by higher propensity for attorney representation and litigation, longer settlement times, and higher settlement values. Certain jurisdictions with expanded liability theories and higher damage awards pose heightened challenges. We are closely monitoring these jurisdictions and the broader trends across our business.

The unfavorable prior year casualty reserve development in First Quarter 2024 was primarily due to these social inflationary impacts. In response to social inflationary impacts, we have been embedding higher severity assumptions in our initial loss ratio estimates in recent years, which more recently are materializing in actual paid results. Despite planning for higher expected loss trends, claim emergence on paid losses in First Quarter 2024 exceeded our expectations and drove the unfavorable prior year development of $50.0 million, primarily in accident years 2020 through 2023. There was no prior year casualty reserve development in First Quarter 2023.

Additionally, the combined ratio was impacted by an increase in current year casualty loss costs of 4.5 points in First Quarter 2024 compared to First Quarter 2023, primarily driven by an increase to our loss trend expectations in response to increases in social inflationary impacts.

We believe that social inflation and elevated loss trends are an industry dynamic, and may lead to an acceleration of rate increases in this line of business. During First Quarter 2024, our renewal pure price increase in this line of business was 6.5%, up from 5.7% last quarter, and 5.4% for full-year 2023. We expect increases in our general liability pricing to accelerate in the coming months.

The favorable prior year casualty reserve development in First Quarter 2024 was primarily due to lower loss severities in accident years 2021 and prior. The favorable prior year casualty reserve development in First Quarter 2023 was primarily due to improved loss severities in accident years 2020 and prior.

In addition, the combined ratio benefited from a decrease in the underwriting expense ratio of 1.2 points in First Quarter 2024, compared to First Quarter 2023, primarily due to premium growth outpacing the growth in underwriting expenses.

Offsetting the combined ratio decreases mentioned above, the First Quarter 2024 combined ratio was adversely impacted by an increase in current year casualty loss costs of 3.5 points, primarily driven by the negative rate environment that has been impacting this line for several years.

We are taking aggressive actions to improve the profitability of this business by continuing to prioritize additional rate filings on a state-by-state basis to mitigate inflationary impacts, and refining our pricing factors. These filed rate increases began to take effect early in 2023, increasing in number and magnitude throughout the year, have continued into 2024, and are expected to continue throughout the year. Our 14.3% renewal pure price increase achieved in First Quarter 2024 met our expectations, and keeps us on track to achieve an increase in excess of 20% for the full year.

The increase in NPE in First Quarter 2024 compared to First Quarter 2023 resulted from the same impacts to NPW described above.

The loss and loss expense ratio decreased 8.2 points in First Quarter 2024 compared to First Quarter 2023, driven by the following:


	First Quarter 2024				First Quarter 2023
($ in millions)	Loss and Loss Expense Incurred		Impact on Loss and Loss Expense Ratio		Loss and Loss Expense Incurred	Impact on Loss and Loss Expense Ratio	Change in Ratio
Net catastrophe losses	$	11.8	11.4	pts	14.6	17.9	(6.5)	pts
Non-catastrophe property loss and loss expenses	41.9		40.3		33.8	41.3	(1.0)
Unfavorable prior year casualty reserve development	—		—		2.0	2.4	(2.4)

Total	$	53.7	51.7		50.4	61.6	(9.9)

The decrease in net catastrophe losses in First Quarter 2024 compared to First Quarter 2023, was primarily due to two large wind and thunderstorm events in First Quarter 2023 that primarily impacted our homeowners line of business.

We experienced $5.0 million of favorable prior year casualty reserve development on our homeowners line of business in First Quarter 2024, primarily due to lower loss severities in accident years 2021 and prior. This favorable development was offset by $5.0 million of unfavorable prior year casualty reserve development on our personal automobile line of business in First Quarter 2024, primarily driven by increased loss severities in accident years 2021 through 2023. The unfavorable prior year casualty reserve development in First Quarter 2023 was primarily due to increased loss severities in accident year 2022 on our personal automobile line of business.

In addition, the loss and loss expense ratio was adversely impacted by an increase in current year casualty loss costs of 1.8 points in First Quarter 2024 compared to First Quarter 2023, primarily due to an expected increase in claim frequencies in the current year.

The underwriting expense ratio decreased 2.7 points in First Quarter 2024 compared to First Quarter 2023, primarily due to premium growth outpacing the growth in underwriting expenses.

NPW grew 24% in First Quarter 2024 compared to First Quarter 2023, reflecting renewal pure price increases and higher direct new business as shown in the table below. In addition, NPW growth in First Quarter 2024 benefited from both property and casualty exposure growth on renewal policies, driven by increased property values, as well as higher rate per exposure.

The increase in NPE in First Quarter 2024 compared to First Quarter 2023 resulted from the same impacts to NPW described above.

The loss and loss expense ratio increased 3.9 points in First Quarter 2024 compared to First Quarter 2023, primarily driven by the following:


	First Quarter 2024				First Quarter 2023

While the frequency of wind and thunderstorm events remained largely consistent, the severity of these events was lower in First Quarter 2024 compared to First Quarter 2023, resulting in a decrease in net catastrophe losses.

We experienced higher non-catastrophe property loss and loss expenses in First Quarter 2024 compared to First Quarter 2023, primarily due to several large fires, reflecting the continued variability from period to period that is normally associated with our E&S property line of business.

There was no prior year casualty reserve development in First Quarter 2024. The favorable prior year casualty reserve development in First Quarter 2023 was primarily due to lower severities in accident years 2021 and prior.

In addition, the loss and loss expense ratio was favorably impacted by a decrease in current year casualty loss costs of 2.3 points in First Quarter 2024 compared to First Quarter 2023, primarily due to the mix of business between our property and casualty lines of business. Our E&S property line of business, which has a lower loss ratio compared to our E&S casualty line of business, represented a larger portion of this segment in First Quarter 2024 compared to First Quarter 2023, resulting in a lower blended current year loss cost in First Quarter 2024.

The 1.3-point decrease in the underwriting expense ratio in First Quarter 2024 compared to First Quarter 2023, was primarily due to premium growth outpacing the growth in underwriting expenses.

Investments

Our investment portfolio's objectives are to maximize after-tax net investment income and generate long-term growth in book value per share by maximizing the overall total return of the portfolio by investing the premiums we receive from our insurance operations and the amounts generated through our capital management strategies, which may include debt and equity security issuances. We balance those objectives against prevailing market conditions, capital preservation considerations, and our enterprise risk-taking appetite. We maintain (i) a well-diversified portfolio across issuers, sectors, and asset classes and (ii) a high credit quality fixed income securities portfolio with a duration and maturity profile at an acceptable risk level that provides ample liquidity.

The effective duration of our fixed income and short-term investments was 4.0 years as of March 31, 2024. The effective duration is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. Purchases and sales are made with the intent of maximizing investment returns in the current market environment, while balancing capital preservation.

Our fixed income and short-term investments represented 92% of our invested assets and had investment grade holdings representing 96% of the total debt portfolio as of March 31, 2024 and December 31, 2023. Our fixed income and short-term investments portfolio had a weighted average credit rating of "A+" as of March 31, 2024 and "AA-" as of December 31, 2023.

For further details on the composition, credit quality, and various risks to which our portfolio is subject, see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk.” of our 2023 Annual Report.

Table of Contents

After-tax net investment income earned increased 17% in First Quarter 2024 compared to First Quarter 2023, primarily driven by active portfolio management and the reinvestment of cash flows in a higher interest rate environment, which provided the opportunity to increase the embedded pre-tax book yield by 60 basis points over the course of 2023. During First Quarter 2024, our pre-tax book yield improved an additional six basis points, bringing our pre-tax book yield to 4.8% as of March 31, 2024.

Realized and Unrealized Gains and Losses

When evaluating securities for sale, our general philosophy is to reduce our exposure to securities and sectors based on economic evaluations of whether (i) the fundamentals for that security or sector have deteriorated or (ii) the timing is appropriate to opportunistically trade for other securities with better economic-return characteristics. Net realized and unrealized gains and losses for the indicated periods were as follows:

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 our operating and growth needs.

Liquidity

We manage liquidity by generating sufficient cash flows to meet our business operations' short-term and long-term cash requirements. As discussed further below, we adjust our liquidity requirements based on economic conditions, market conditions, and future cash flow commitments.

Sources of Liquidity

Sources of cash for the Parent historically have consisted of dividends from the Insurance Subsidiaries, the investment portfolio held at the Parent, borrowings under third-party lines of credit, intercompany revolving demand loan agreements with certain Insurance Subsidiaries, and the issuance of equity (common or preferred) and debt securities. We continue to monitor these sources, considering our short-term and long-term liquidity and capital preservation strategies.

Table of Contents

The Parent's cash and components of its investment portfolio were as follows:


($ in thousands)	March 31, 2024		December 31, 2023
Fixed income securities	$	328,821	421,089
Equity securities	53,123		50,920
Short-term investments	77,670		17,671
Alternative investments	16,648		18,134
Cash	124		180
Total investments and cash	$	476,386	507,994

Short-term investments have historically been maintained in “AAA” rated money market funds and fixed income securities are comprised of high-quality, liquid government and corporate securities.

The amount and composition of the Parent's investment portfolio may change over time 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 stockholders, asset allocation investment decisions, inorganic growth opportunities, debt retirement, and share repurchases. Our target is for the Parent to maintain liquid investments of at least twice its expected annual net cash outflow needs, or $210 million.

Insurance Subsidiary Dividends

The Insurance Subsidiaries generate liquidity through insurance float, created by collecting premiums and earning investment income before paying claims. The period of float can extend over many years. Our investment portfolio consists of securities with maturity dates that continually provide a source of cash flow for claims payments in the ordinary course of business. To protect our Insurance Subsidiaries' capital, we purchase reinsurance coverage for significantly large claims or catastrophes that may occur.

The Insurance Subsidiaries paid $44 million in total dividends to the Parent in First Quarter 2024. As of December 31, 2023, our allowable ordinary maximum dividend is $316 million for 2024. 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 statutory surplus reported in its annual statements as of the preceding December 31. Although domiciliary state insurance regulators have historically 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 stockholders if either (i) the Parent would be unable to pay its debts as they become 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 stockholders is also impacted by (i) covenants in its credit agreement 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 from being 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. "Equity," 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 2023 Annual Report.

Line of Credit

On November 7, 2022, the Parent entered into a Credit Agreement with the lenders named therein (the “Lenders”) and Wells Fargo Bank, National Association, 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' consent. No borrowings were made under the Line of Credit in First Quarter 2024. The Line of Credit will mature on November 7, 2025, and has a variable interest rate based on the Parent’s debt ratings. We expect to continue to maintain a credit facility for liquidity purposes. 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 2023 Annual Report. We met all covenants under our Line of Credit as of March 31, 2024.

Table of Contents

Four Insurance Subsidiaries are members of Federal Home Loan Bank ("FHLB") branches, as shown in the following table. Membership requires the ownership of branch stock and includes the right to access liquidity. All Federal Home Loan Bank of Indianapolis ("FHLBI") and Federal Home Loan Bank of New York ("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.


Branch			Insurance Subsidiary Member
FHLBI			Selective Insurance Company of South Carolina1 Selective Insurance Company of the Southeast1
FHLBNY			Selective Insurance Company of America Selective Insurance Company of New York ("SICNY")

1These subsidiaries are jointly referred to as the "Indiana Subsidiaries" because 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. SICNY is domiciled in New York, which limits its FHLBNY borrowings to the lesser of 5% of admitted assets for the most recently completed fiscal quarter or 10% of the previous year-end's admitted assets. As of March 31, 2024, we had remaining capacity of $528.3 million for FHLB borrowings, with a $21.3 million additional stock purchase requirement to allow the member companies to borrow their remaining capacity amounts.

Short-term Borrowings

We did not make any short-term borrowings from FHLB branches during First Quarter 2024.

Intercompany Loan Agreements

The Parent has lending agreements with the Indiana Subsidiaries, approved by the Indiana Department of Insurance, that provide the Parent with additional intercompany liquidity. Like 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 $62.0 million as of March 31, 2024, and $67.0 million as of December 31, 2023. The remaining capacity under these intercompany loan agreements was $119.5 million as of March 31, 2024, and $114.5 million as of December 31, 2023. Additionally, we have other insurance regulator-approved intercompany agreements in place that facilitate liquidity management between the Parent and the Insurance Subsidiaries to enhance flexibility.

Capital Market Activities

The Parent had no private or public stock issuances during First Quarter 2024. In addition, we had no common stock share repurchases during First Quarter 2024 under our existing share repurchase program. We had $84.2 million of remaining capacity under our share repurchase program as of March 31, 2024. For additional information on the share repurchase program, refer to Note 17. “Equity” in Item 8. "Financial Statements and Supplementary Data." of our 2023 Annual Report.

Uses of Liquidity

The Parent uses the liquidity generated from the sources discussed above to pay dividends to our stockholders, among other things. Dividends on shares of the Parent's common and preferred stock are declared and paid at the discretion of the Board based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors. On May 1, 2024, our Board declared:

•A quarterly cash dividend on common stock of $0.35 per common share that is payable June 3, 2024, to holders of record on May 15, 2024; and

•A quarterly cash dividend of $287.50 per share on our 4.60% Non-Cumulative Preferred Stock, Series B (equivalent to $0.28750 per depository share) payable on June 17, 2024, to holders of record as of June 3, 2024.

Our ability to meet our interest and principal repayment obligations on our debt and 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 dividends, if necessary, and/or (iii) the availability of other sources of liquidity to the Parent. Our next borrowing principal repayment is $60 million to FHLBI due 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.

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 March 31, 2024, we had GAAP stockholders' equity of $3.0

Table of Contents

billion and statutory surplus of $2.8 billion. With total debt of $503.3 million at March 31, 2024, our debt-to-capital ratio was 14.3%. 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 2023 Annual Report.

The following table summarizes certain contractual obligations we had at March 31, 2024, that may require us to invest additional amounts into our investment portfolio, which we would fund primarily with operating cash flows.



($ in millions)	Amount of Obligation
Alternative and other investments	$	259.7
Non-publicly traded collateralized loan obligations in our fixed income securities portfolio	96.8
Non-publicly traded common stock within our equity portfolio	32.6
CMLs	1.6
Privately-placed corporate securities	33.8
Total	$	424.5

There is no certainty (i) that any such additional investments will be required, and (ii) about the timing of funding. We expect to have the capacity to fund these commitments through our normal operating and investing activities as they come due.

Our current and long-term material cash requirements associated with (i) loss and loss expense reserves, (ii) contractual obligations under operating and financing leases for office space and equipment, and (iii) notes payable, funded primarily with operating cash flows, have not materially changed since December 31, 2023. The Insurance Subsidiaries' net loss and loss expense reserves duration was 3.1 years at December 31, 2023.

Our other cash requirements include, without limitation, dividends to stockholders, capital expenditures, and other operating expenses, including commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes.

As of March 31, 2024, and December 31, 2023, we had no (i) material guarantees on behalf of others and trading activities involving non-exchange traded contracts accounted for at fair value, (ii) material transactions with related parties other than those disclosed in Note 18. “Related Party Transactions” in Item 8. “Financial Statements and Supplementary Data.” of our 2023 Annual Report, and (iii) 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.

We continually monitor our cash requirements and the capital resources we maintain at the holding company and Insurance 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 adjusting common stockholders’ dividends.

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders and enhance our financial strength and underwriting capacity. We have a profitable underwriting portfolio and solid capital base, positioning us well to take advantage of potential market opportunities.

Book value per common share increased 2% to $46.17 as of March 31, 2024, from $45.42 as of December 31, 2023, driven by $1.31 in net income available to common stockholders per diluted common share, partially offset by a $0.22 increase in unrealized losses on our fixed income securities portfolio and $0.35 in dividends to our common stockholders. The increase in net unrealized losses on our fixed income securities was primarily driven by an increase in benchmark U.S. Treasury rates. Our adjusted book value per share, which is book value per share excluding total after-tax unrealized gains or losses on investments included in accumulated other comprehensive income (loss), increased to $50.97 as of March 31, 2024, from 50.03 as of December 31, 2023.

Cash Flows

Net cash provided by operating activities decreased to $114.2 million in First Quarter 2024, compared to $135.8 million in First Quarter 2023, primarily driven by reduced underwriting results in our insurance operations. For more information on our underwriting results, refer to "Insurance Operations" above in this MD&A.

Table of Contents

Net cash used in investing activities decreased to $86.0 million in First Quarter 2024, compared to $98.2 million in First Quarter 2023, as a result of investing less cash from operating activities. Operating cash flows were 10% of NPW in First Quarter 2024 compared to 14% of NPW in First Quarter 2023.

Net cash used in financing activities remained relatively flat at $29.6 million in First Quarter 2024, compared to $27.1 million in First Quarter 2023.

Ratings

Our ratings are as follows:


Nationally Recognized Statistical Rating Organizations	Financial Strength Rating	Outlook
AM Best Company	A+	Stable
Moody's Investors Services	A2	Positive
Fitch Ratings	A+	Stable
Standard & Poor's Global Ratings ("S&P")	A	Stable

On February 28, 2024, S&P reaffirmed our “A” rating with a “stable” outlook. In taking this rating action, S&P cited our (i) strong financial and business risk profiles, (ii) sound underwriting process that produces profitable operating performance, and (iii) very strong capital adequacy.

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 2023 Annual Report.

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 First Quarter 2024 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 routinely engaged in legal proceedings with inherently unpredictable outcomes that 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 March 31, 2024, 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 our actions in 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 common stockholders' dividends. We operate in a continually changing business environment, and new risk factors that we cannot

predict or assess may emerge at anytime. Consequently, we can neither predict such new risk factors nor assess the potential future impact on our business. There have been no material changes from the risk factors disclosed in Item 1A. “Risk Factors.” in our 2023 Annual Report.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

The following table provides information regarding our purchases of our common stock in First Quarter 2024:
