Accounting Policies [Abstract] |
Principles of Consolidation | The condensed consolidated financial statements include the accounts of Kingstone and its wholly-owned subsidiaries: (1) KICO and its wholly-owned subsidiaries, CMIC Properties, Inc. (“Properties”) and 15 Joys Lane, LLC (“15 Joys Lane”), which together, until March 2025, owned the land and building from which KICO operated (see Note 14 - Sale of Real Estate), and (2) Cosi. All significant inter-company account balances and transactions have been eliminated in consolidation.
Use of Estimates | The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and assumptions, and includes the reserves for losses and loss adjustment expense (“LAE”), which are subject to estimation errors due to the inherent uncertainty in projecting ultimate claim amounts that will be reported and settled over a period of many years. In addition, estimates and assumptions associated with loss and LAE recoverable under reinsurance contracts and other receivables or payable under reinsurance contracts related to contingent ceding commission revenue require judgments by management. On an ongoing basis, management reevaluates its assumptions and the methods for calculating these estimates. Actual results may differ significantly from the estimates used in preparing the condensed consolidated financial statements.
Accounting Changes | In December 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance is effective for the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.
Recent Accounting Pronouncements | In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses ("ASU 2024-03"). ASU 2024-03 requires disaggregated disclosure of income statement expenses. ASU 2024-03 does not change the expense captions currently presented on the income statement; rather it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for annual reporting periods, as amended by ASU 2025-01, beginning after December 15, 2026, and interim reporting periods within fiscal years beginning after December 15, 2027. ASU 2024-03 can be applied on a prospective basis; however, retrospective application is permitted. Early adoption is permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures. The Company has determined that all other recently issued accounting pronouncements will not have a material impact on its consolidated financial position, results of operations and cash flows, or do not apply to its operations.
