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 second quarters ended June 30, 2024 (“Second Quarter 2024”) and June 30, 2023 (“Second Quarter 2023”), and the six-month periods ended June 30, 2024 ("Six Months 2024") and June 30, 2023 ("Six Months 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 a material 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
6

are required annually: (i) specific required categories in the rate reconciliation, (ii) additional information for reconciling items 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 a material impact on our financial condition or results of operations.
