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 third quarters ended September 30, 2023 (“Third Quarter 2023”) and September 30, 2022 (“Third Quarter 2022”), and the nine-month periods ended September 30, 2023 ("Nine Months 2023") and September 30, 2022 ("Nine Months 2022"). 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, 2022 (“2022 Annual Report”) filed with the SEC.

NOTE 2. Adoption of Accounting Pronouncements 
In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the 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, 2024, as permitted by ASU 2022-06, Reference Rate Reform (Topic 848) — Deferral of the Sunset Date of Topic 848 issued in December 2022. We adopted this guidance in the first quarter of 2023. We are not required to measure the effect of adoption on our financial position, cash flows, or net income because the guidance provides relief from accounting for the effects of the change to a replacement rate.

Pronouncements to be effective in the future
In June 2022, the FASB issued 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. Early adoption is permitted. We are currently evaluating the impact of this guidance.

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 are currently evaluating the impact of this guidance.

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 2022 Annual Report. Accrued interest on AFS securities was $60.7 million as of September 30, 2023, and $56.4 million as of December 31, 2022. We did not record any (i) write-offs of accrued interest during Nine Months 2023, or (ii) material write-offs of accrued interest in Nine Months 2022.

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. The increase in gross unrealized losses as of September 30, 2023, compared to December 31, 2022, was primarily driven by an increase in benchmark U.S. Treasury rates, partially offset by a 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 2022 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 September 30, 2023. 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 September 30, 2023, 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.

Net realized and unrealized investment losses decreased $18.8 million in Third Quarter 2023 compared to Third Quarter 2022, primarily due to (i) an increase in valuations reflecting the current public equities market, and (ii) a decrease in net realized losses on disposals from our AFS fixed income securities portfolio.

Net realized and unrealized investment losses decreased $100.0 million in Nine Months 2023 compared to Nine Months 2022, primarily due to (i) a credit loss benefit recorded on our AFS fixed income securities portfolio in Nine Months 2023 compared to credit loss expense recorded in Nine Months 2022, and (ii) an increase in valuations reflecting the current public equities market. The credit loss benefit in Nine Months 2023 reflected the tightening of credit spreads, partially offset by rising benchmark U.S. Treasury rates.

Net unrealized gains and losses recognized in income on equity securities, as reflected in the table above, included the following:

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.

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 September 30, 2023, 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.

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 we 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.

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, and 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.

Factors that could cause our actual results to differ materially from what we project, forecast, or estimate in forward-looking statements are discussed in further detail 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 anytime. We can neither predict these new risk factors nor assess their impact, if any, on our businesses or the extent 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.

22

Table of Contents
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, 2022 ("2022 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 2022 Annual Report filed with the United States ("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 third quarters ended September 30, 2023 (“Third Quarter 2023”) and September 30, 2022 (“Third Quarter 2022”); and the nine-month periods ended September 30, 2023 ("Nine Months 2023") and September 30, 2022 ("Nine Months 2022");
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 2022 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; and (iii) reinsurance. These estimates and judgments require the 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 37 through 45 of our 2022 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.

Our non-GAAP operating ROE in both Third Quarter 2023 and Nine Months 2023 was above our full-year 2023 target non-GAAP operating ROE of 12%, and above our non-GAAP operating ROE in the same prior-year periods.

The increase in our non-GAAP operating ROE in Third Quarter 2023 of 4.5 points and Nine Months 2023 of 1.6 points, compared to the same prior-year periods was primarily driven by an increase in after-tax net investment income of $28.7 million, or 4.2-points, in Third Quarter 2023 and $64.4 million, or 3.8-points, in Nine Months 2023, compared to the same prior-year periods. The increase in both periods resulted from greater after-tax net investment income earned on our fixed income securities portfolio due to higher book yields received from the investment of operating and investing cash flows over the past year in the higher interest rate environment.

The increase in after-tax net investment income in Nine Months 2023 compared to Nine Months 2022 was partially offset by a a $40.6 million, or 2.1-point, reduction in after-tax underwriting income, primarily resulting from (i) an increase in net catastrophe losses in Nine Months 2023 compared to Nine Months 2022, and (ii) lower favorable prior year casualty reserve development in Nine Months 2023 compared to Nine Months 2022. Pre-tax net catastrophe losses in Nine Months 2023 were $219.9 million, or 7.8 points on the combined ratio, compared to $100.2 million, or 4.0 points, in Nine Months 2022. We were impacted by 60 Property Claim Services ("PCS") named events in Nine Months 2023, mostly in our Midwest, Southern, and East Coast footprint states. None of these events were large enough to attach to our catastrophe reinsurance treaty. Nine Months 2022 included 45 PCS named events, mostly in our Midwest, Southern, and East Coast footprint states.

In addition, a decrease in net realized and unrealized investment losses in Third Quarter 2023 and Nine Months 2023 compared to the same prior-year periods drove the increase in our ROE of 2.6 points in Third Quarter 2023 and 4.2 points in Nine Months 2023 compared to the same prior-year periods. The decrease in Third Quarter 2023 compared to Third Quarter 2022 was primarily due to (i) an increase in valuations reflecting the current public equities market, and (ii) a decrease in net realized losses on disposals from our AFS fixed income securities portfolio. The decrease in Nine Months 2023 compared to Nine Months 2022 was primarily due to (i) a credit loss benefit recorded on our AFS fixed income securities portfolio in Nine Months 2023 compared to credit loss expense recorded in Nine Months 2022, and (ii) an increase in valuations reflecting the current public equities market. The credit loss benefit in Nine Months 2023 reflected the tightening of credit spreads, partially offset by rising benchmark U.S. Treasury rates.

Outlook
We entered 2023 well positioned to navigate the on-going challenges of elevated economic and social inflation, increased interest rates, and financial market volatility. Our overall Nine Months 2023 financial results were strong with 15% NPW growth and a 13.2% non-GAAP operating ROE, which was above our full-year target of 12%.

We continue to focus on several foundational areas to position us for ongoing success:

Delivering on our strategy for continued disciplined and profitable growth by:
Executing our distribution model strategy that emphasizes franchise value, meaning we focus on appointing and having meaningful, close business relationships with high-quality, independent distribution partners who value our relationships and provide us the opportunity to grow profitably with them;
Continuing to provide our teams with sophisticated tools and technologies to inform underwriting decisions at a granular level, which contributes to strong and stable underwriting performance over time. We are actively working towards deploying our new underwriting platform in our E&S segment, which also improves agents' ease of interactions with us;
Achieving Standard Commercial Lines and E&S 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 utilization of our enhanced small business platform;
Expanding our geographic footprint. In 2022, we began writing Standard Commercial Lines business in Vermont, Alabama, and Idaho. We expect to write new business in West Virginia and Maine in early 2024, and Washington, Oregon, and Nevada in late 2024. We plan to expand our Standard Commercial Lines footprint into most of the contiguous U.S. over time;
Increasing customer retention by delivering a superior omnichannel experience and offering value-added technologies and services;
Aggressively managing our Standard Personal Lines segment by prioritizing additional rate filings on a state-by-state basis and refining pricing for both catastrophe and non-catastrophe perils. These filed rate increases began to take effect on a written basis during the first quarter of 2023 and continued to take effect through Third Quarter 2023. We expect our overall written renewal rate to be 9% in the fourth quarter of 2023 and in the range of approximately 20% to 25% in 2024, subject to regulatory approvals. In addition, other underwriting actions include the following:
Seeking to improve our homeowners’ line of business profitability through the introduction of new policy terms and conditions, including (i) coverage for actual cash value based on a schedule of factors rather than replacement cost on older roofs, and (ii) implementing mandatory wind/hail deductibles in states exposed to severe convective storms; and
Accelerating 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 the strong coverage and servicing capabilities that we offer.

Continuing to further develop our culture centered on the values of diversity, equity, and inclusion that fosters innovation, idea generation, and the development of a group of specially trained leaders who can guide us successfully into the future.

For 2023, our full-year expectations are as follows:

A GAAP combined ratio of 96.5%, unchanged from last quarter, including net catastrophe losses of 6.5 points, up from prior guidance of 6.0 points. Our combined ratio estimate assumes no additional prior year casualty reserve development;
After-tax net investment income of $310 million, up from prior guidance of $300 million. After-tax net investment income includes $20 million of after-tax net investment income from our alternative investments, down from prior guidance of $30 million;
An overall effective tax rate of approximately 21.0%, which assumes an effective tax rate of 20.0% for net investment income and 21.0% for all other items; and
Weighted average shares of 61.0 million on a fully diluted basis, which assumes no additional share repurchases we may make under our authorization.

The NPW growth of 17% in Third Quarter 2023 and 15% in Nine Months 2023 compared to the same prior-year periods reflected (i) overall renewal pure price increases, and (ii) higher direct new business, as shown in the following table:

Our NPW growth in Third Quarter 2023 and Nine Months 2023 also benefited from strong retention and exposure growth on renewal policies.

The increase in NPE in Third Quarter 2023 and Nine Months 2023 compared to the same prior-year periods resulted from the same impacts to NPW described above.

Loss and Loss Expenses
The loss and loss expense ratio increased 1.7 points in Third Quarter 2023 and 3.0 points in Nine Months 2023 compared to the same prior-year periods, primarily due to the following:

NPW growth of 17% in Third Quarter 2023 and 14% in Nine Months 2023, compared to the same prior-year periods benefited from exposure growth on renewal policies, strong retention, renewal pure price increases, and higher direct new business.

The combined ratio decreased by 3.4 points in Third Quarter 2023 and 1.1 points in Nine Months 2023, compared to the same prior-year periods, primarily driven by a decrease in the underwriting expense ratio of 2.3 points in Third Quarter 2023 and 1.5 points in Nine Months 2023, compared to the same prior-year periods, as discussed in the "Standard Commercial Lines Segment" section above.

In addition, while there was no prior year casualty reserve development in Third Quarter 2023 and Third Quarter 2022, Nine Months 2023 was impacted by less favorable prior year casualty reserve development as follows:

This line of business has experienced a long-term historical trend of meaningful severity increases, which have been largely offset by decreases in claim frequencies. In response to potential social inflationary impacts, we have been embedding higher severity assumptions in our initial loss ratio estimates in recent years, which we are seeing materialize in actual results. As the trend of lower frequencies has continued, those initial estimates have remained reasonable. However, if the favorable frequency trend moderates and severities emerge higher than expected, we could see additional pressure on this line.

The favorable prior year casualty reserve development in Nine Months 2022 was primarily attributable to improved loss severities in accident years 2019 and prior.

Third Quarter 2023 and Nine Months 2023 experienced elevated net catastrophe losses as discussed in the "Insurance Operations" section above. We had lower non-catastrophe property loss and loss expense ratios in Third Quarter 2023 and Nine Months 2023 compared to the same prior-year periods. While this change continues to reflect the variability from period to period that is normally associated with the commercial property line of business, we have also seen a decline in claim frequencies in the current year. We continue to manage our long-term profitability through (i) price increases, and (ii) targeted underwriting actions, including an ongoing focus on appropriate policy terms and conditions and achieving accurate insurance to value ratios.

The combined ratio was also impacted by a decrease in the underwriting expense ratio of 1.4 points in Third Quarter 2023 and 0.3 points in Nine Months 2023, compared to the same prior-year periods, as discussed in the "Standard Commercial Lines Segment" section above.

Net catastrophe losses in both current- and prior-year periods exceeded our 10-year historical average, with Third Quarter 2023 and Nine Months 2023 being elevated over the comparable prior year periods, as discussed in the "Insurance Operations" section above.

We experienced elevated non-catastrophe property loss and loss expenses in Third Quarter 2023 and Nine Months 2023, driven by higher personal automobile physical damage and homeowners property losses. The higher automobile damage losses resulted from increasing claim frequencies, as well as greater severities from inflationary and supply chain impacts that have increased labor and repair costs, and claim duration. Higher homeowners property losses were attributable to elevated severities due to (i) higher construction costs impacted by economic inflation, and (ii) increasing home values resulting from higher average policy sizes from our mass affluent market strategy. The likely continuation of elevated non-catastrophe property loss and loss expenses, coupled with renewal pure price increases below loss trend, will put pressure on this segment's profitability in the near-term, while our filed rate increases approach current loss cost levels.

The unfavorable prior year casualty reserve development in Third Quarter 2023 and Nine Months 2023 was primarily due to increased loss severities in accident year 2022. There was no prior year casualty reserve development in Third Quarter 2022 or Nine Months 2022.

In addition, the loss and loss expense ratio was impacted by an increase in current year casualty loss costs of 8.7 points in Third Quarter 2023, and 4.8 points in Nine Months 2023, compared to the same prior-year periods, in response to (i) elevated prior- year severities, which influenced our current-year severity estimates, and (ii) increased claim frequencies in the current year.

The underwriting expense ratio decreased 3.2 points in Third Quarter 2023 compared to Third Quarter 2022, and 0.6 points in Nine Months 2023 compared to Nine Months 2022, primarily due to premium growth outpacing the growth in underwriting expenses.

To address profitability challenges in this segment and position us for ongoing success, we are aggressively managing this business by continuing to prioritize rate filings on a state-by-state basis to mitigate these inflationary impacts, and refining pricing for both catastrophe and non-catastrophe perils. These filed rate increases began to take effect on a written basis during the first quarter of 2023 and continued to take effect through Third Quarter 2023. We expect the number of rate filings and their rate impacts to continue to increase in the fourth quarter of 2023 and throughout 2024. In addition, we are seeking to improve profitability within our homeowners' line of business by introducing new policy terms and conditions, including (i) coverage for actual cash value based on a schedule of factors rather than replacement cost on older roofs, and (ii) implementing mandatory wind/hail deductibles in states exposed to severe convective storms.

NPW growth of 25% in Third Quarter 2023 and 21% in Nine Months 2023, compared to the same prior-year periods, reflected renewal pure price increases and higher direct new business as shown in the table below. In addition, NPW growth in Third Quarter 2023 and Nine Months 2023 benefited from both property and casualty exposure growth on renewal policies driven by higher rates and increased construction costs resulting from economic inflation.

The increase in NPE in Third Quarter 2023 and Nine Months 2023 compared to the same prior-year periods resulted from the same impacts to NPW described above.

The loss and loss expense ratio decreased 9.1 points in Third Quarter 2023 and 3.8 points in Nine Months 2023, compared to the same prior-year periods, primarily driven by the following:

We experienced elevated net catastrophe losses in Nine Months 2023 compared to Nine Months 2022, as discussed in the "Insurance Operations" section above.

The favorable prior year casualty reserve development in Nine Months 2023 was primarily due to improved loss severities in accident years 2021 and prior. There was no prior year casualty reserve development in Third Quarter 2022 and Nine Months 2022.

In addition, the loss and loss expense ratio was favorably impacted by a decrease in current year casualty loss costs of 4.5 points in Third Quarter 2023 and 4.0 points in Nine Months 2023, compared to the same prior-year periods. Our E&S casualty lines results have improved over recent years from several underwriting and claims initiatives and strong rate increases. The decrease in current year casualty loss costs reflected the impacts of these actions.

Reinsurance
We successfully completed negotiations of our July 1, 2023 excess of loss treaties, which cover our Standard Commercial Lines, Standard Personal Lines, and E&S Lines.

We renewed the Casualty Excess of Loss Treaty ("Casualty Treaty") with substantially the same structure as the expiring treaty. The treaty year 2023 deposit premium increased $28.3 million, or 33%, reflecting (i) higher projected subject earned premium due to growth in our book of business, including pure renewal rate increases; (ii) a modest reinsurance rate increase; and (iii) additional reinstatement coverage in the first three layers.

We renewed the Property Excess of Loss Treaty (“Property Treaty”) and elected to increase the first layer retention from $3.0 million to $5.0 million. We elected to increase our retention in recognition of the growing overall size of our book of business and to manage our overall reinsurance cost while maintaining an appropriate level of capital and earnings protection. In addition, the first layer reinstatement provision was revised to 15 free reinstatements, from the expiring treaty's unlimited free reinstatements. The attachment points and limits for the subsequent layers remained the same. The treaty year deposit

Table of Contents
premium decreased $5.6 million, or 11%, reflecting the premium reduction associated with the aforementioned first layer retention increase, partially offset by a risk-adjusted rate increase and an increase in exposure.

The following table summarizes the Property Treaty and Casualty Treaty arrangements covering our Insurance Subsidiaries:

Treaty NameReinsurance CoverageTerrorism Coverage
Property Excess of Loss (covers all insurance operations)
There are three layers covering 100% of $65 million in excess of $5 million. Losses other than Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA") certified losses are subject to the following reinstatements and annual aggregate limits:

- $5 million in excess of $5 million layer provides 15
        reinstatements, $80 million in aggregate limits;
- $20 million in excess of $10 million layer provides three
        reinstatements, $80 million in aggregate limits; and
- $40 million in excess of $30 million layer provides two
        reinstatements, $120 million in aggregate limits.
All nuclear, biological, chemical, and radioactive ("NBCR") losses are excluded regardless of whether or not they are certified under the TRIPRA. 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 $15 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 48
      reinstatements, $147 million annual aggregate limit;

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 the fixed income securities portfolio, including short-term investments, was 4.1 years as of September 30, 2023. 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 at September 30, 2023 and December 31, 2022. Our fixed income and short-term investments portfolio had a weighted average credit rating of "A+" as of September 30, 2023 and "AA-" as of December 31, 2022, with investment grade holdings representing 96% of the total portfolio on both dates. The weighted average credit rating decline reflects the impact from the recent Fitch Ratings ("Fitch") downgrade of the U.S. sovereign ratings in Third Quarter 2023. This downgrade impacted the credit ratings of our U.S. government and government agency securities and agency mortgage-backed securities, which represented about 17% of our fixed income and short-term investments portfolio as of September 30, 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 2022 Annual Report.

Invested assets increased $358.4 million at September 30, 2023, compared to December 31, 2022, reflecting our active investment of operating and investing cash flows in 2023. Operating cash flows during Nine Months 2023 were 17% of NPW. The increase in invested assets was partially offset by a $92.1 million increase in pre-tax unrealized losses during Nine Months 2023. The increase in pre-tax unrealized losses was primarily driven by an increase in benchmark U.S. Treasury rates, partially offset by a tightening of credit spreads.

After-tax net investment income earned increased 56% in Third Quarter 2023 and 39% in Nine Months 2023, compared to the same prior-year periods, primarily driven by an increase in income earned on our fixed income securities portfolio due to higher book yields received from the investment of operating and investing cash flows over the past year in the higher interest rate environment.

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:

Net realized and unrealized investment losses decreased 73% in Third Quarter 2023 compared to Third Quarter 2022, primarily due to (i) an increase in valuations reflecting the current public equities market, and (ii) a decrease in net realized losses on disposals from our AFS fixed income securities portfolio.

Net realized and unrealized investment losses decreased 92% in Nine Months 2023 compared to Nine Months 2022, primarily due to (i) a credit loss benefit recorded on our AFS fixed income securities portfolio in Nine Months 2023 compared to credit loss expense recorded in Nine Months 2022, and (ii) an increase in valuations reflecting the current public equities market. The credit loss benefit in Nine Months 2023 reflected the tightening of credit spreads, partially offset by rising benchmark U.S. Treasury rates.

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 the short-term and long-term cash requirements of our business operations. We adjust our liquidity requirements based on economic conditions, market conditions, and future cash flow commitments, as discussed further below.

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, 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.

The Parent's investment portfolio includes (i) short-term investments that have historically been maintained in “AAA” rated
38

Table of Contents
money market funds, (ii) high-quality, highly liquid government and corporate fixed income securities, (iii) equity securities, (iv) alternative investments, and (v) a cash balance. In the aggregate, Parent cash and total investments amounted to $486 million at September 30, 2023, and $484 million at December 31, 2022.

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 highly liquid investments of at least twice its expected annual net cash outflow needs, or $180 million.

Insurance Subsidiary Dividends
The Insurance Subsidiaries generate liquidity through insurance float, which is 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 $80 million in total dividends to the Parent in Nine Months 2023. The Insurance Subsidiaries' Boards of Directors did not declare a dividend payable to the Parent during Third Quarter 2023 and do not intend to declare a dividend in the fourth quarter of 2023 to support the continued growth of the Insurance Subsidiaries. As of December 31, 2022, our allowable ordinary maximum dividend is $283 million for 2023. 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 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 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 2022 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 Nine Months 2023. 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 2022 Annual Report. We met all covenants under our Line of Credit as of September 30, 2023.

Four of the 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.

Table of Contents

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. 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 September 30, 2023, we had remaining capacity of $470.7 million for FHLB borrowings, with a $18.7 million additional stock purchase requirement to allow the member companies to borrow their remaining capacity amounts.

Short-term Borrowings
On April 6, 2023, SICA borrowed $20 million from the FHLBNY at an interest rate of 5.00% that was repaid on May 8, 2023. These funds were used for general corporate purposes.

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. 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 September 30, 2023, and December 31, 2022. The remaining capacity under these intercompany loan agreements was $121.5 million as of both September 30, 2023, and December 31, 2022. 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 Nine Months 2023. In addition, we had no common stock share repurchases during Nine Months 2023 under our existing share repurchase program. We had $84.2 million of remaining capacity under our share repurchase program as of September 30, 2023. For additional information on the share repurchase program, refer to Note 17. “Equity” in Item 8. "Financial Statements and Supplementary Data." of our 2022 Annual Report.

Uses of Liquidity
The Parent's liquidity generated from the sources discussed above is used, among other things, to pay dividends to our stockholders. 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 November 1, 2023, our Board declared:

A 17% increase in the quarterly cash dividend on common stock, to $0.35 per common share, that is payable December 1, 2023, to holders of record on November 15, 2023; 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) payable on December 15, 2023, to holders of record as of November 30, 2023.

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 September 30, 2023, we had GAAP stockholders' equity and statutory surplus of $2.6 billion. With total debt of $504.6 million at September 30, 2023, 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 2022 Annual Report.

Table of Contents
The following table summarizes certain contractual obligations we had at September 30, 2023, that may require us to invest additional amounts into our investment portfolio, which we would fund primarily with operating cash flows.

Total$400.2 

There is no certainty (i) that any such additional investments will be required, and (ii) of 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, 2022. The Insurance Subsidiaries' net loss and loss expense reserves duration was 3.1 years at December 31, 2022.

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 September 30, 2023, and December 31, 2022, 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 2022 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 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 a profitable book of business and solid capital base, positioning us well to take advantage of potential market opportunities.

Book value per common share increased 5% to $40.35 as of September 30, 2023, from $38.57 as of December 31, 2022, driven by $3.83 in net income available to common stockholders per diluted common share, partially offset by a $1.31 increase in unrealized losses on our fixed income securities portfolio and $0.90 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, partially offset by a tightening of credit spreads. 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 $48.54 as of September 30, 2023, from $45.49 as of December 31, 2022.

Cash Flows
Net cash provided by operating activities increased to $522.3 million in Nine Months 2023, compared to $485.4 million in Nine Months 2022, primarily driven by higher levels of cash received for premiums.

Net cash used in investing activities increased to $470.0 million in Nine Months 2023, compared to $450.9 million in Nine Months 2022, as a result of investing more cash from operating activities. Operating cash flows during Nine Months 2023 were 17% of NPW.

Net cash used in financing activities decreased to $64.1 million in Nine Months 2023, compared to $70.6 million in Nine

There have been no material changes in the information about market risk set forth in our 2022 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 Third Quarter 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

"Financial Statements." of this Form 10-Q and Item 1A. “Risk Factors.” below in Part II. “Other Information.” As of September 30, 2023, 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 2022 Annual Report.
