Accounting Policies [Abstract] |
Basis of Presentation | 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, 2025 ("First Quarter 2025") and March 31, 2024 ("First Quarter 2024"). 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, 2024 ("2024 Annual Report") filed with the SEC.
