Significant Accounting Policies (Policies)	3 Months Ended
Mar. 31, 2025
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X, and include the accounts of Indemnity and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. For further information, refer to the consolidated financial statements and footnotes included in our Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission ("SEC") on February 27, 2025.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires us 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recently adopted and issued accounting standards and disclosure rules	Recently adopted accounting standards We adopted Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures", effective with the annual reporting period ending December 31, 2024. We applied the guidance retrospectively to prior periods presented in the consolidated financial statements based on the significant segment expense categories identified and disclosed in the period of adoption. As an entity with a single reportable segment, we disclose significant segment expenses that are regularly provided to our chief operating decision maker and included within each reported period of profit or loss, and all applicable disclosures required by Topic 280. The adoption of this guidance had no impact on our consolidated financial statements. The additional disclosures required by this guidance have been included in Note 4, "Segment Information". Recently issued accounting standards and disclosure rules In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures", which requires entities to disclose specific categories in an effective tax rate reconciliation, additional information for reconciling items that meet a quantitative threshold, and certain information about income taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments can be applied on either a prospective or retrospective basis. We plan to adopt the standard in our consolidated financial statements for the year ending December 31, 2025, and we expect the standard will impact certain of our income tax disclosures. In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules under SEC Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", requiring registrants to disclose certain climate-related information in registration statements and annual reports. The final rules include disclosure of climate-related risks that are reasonably likely to have a material impact on a registrant’s business, results of operations or financial condition. Disclosures related to significant effects of severe weather events and other natural conditions and amounts related to carbon offsets and renewable energy credits or certificates are required in the financial statements in certain circumstances. Disclosure requirements will phase in for fiscal years beginning in 2025 and be applied prospectively upon adoption. On April 4, 2024, the SEC issued a voluntary stay on its final rules until legal challenges to the rules are addressed, and on March 27, 2025, the SEC voted to end its defense of the rules and withdrew from the litigation. We continue to monitor the status of these rules pending the court's ultimate decision. In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses", which requires entities to disclose disaggregated information about certain income statement expense line items. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments can be applied on either a prospective or retrospective basis. This will have no impact on our consolidated financial statements, and we are currently evaluating the impact of adoption on our disclosures.
Revenue	The majority of our revenue is derived from the subscriber’s agreement between us and the subscribers (policyholders) at the Exchange. In accordance with the subscriber’s agreement, we retain a management fee calculated as a percentage, not to exceed 25%, of all direct and affiliated assumed written premiums of the Exchange. We allocate a portion of our management fee revenue, currently 25% of the direct and affiliated assumed written premiums of the Exchange, between the two performance obligations we have under the subscriber’s agreement. The first performance obligation is to provide policy issuance and renewal services to the subscribers (policyholders) at the Exchange, and the second is to act as attorney-in-fact on behalf of the subscribers at the Exchange, as well as the service provider for the Exchange's insurance subsidiaries, with respect to all administrative services. The transaction price, including management fee revenue and administrative services reimbursement revenue, includes variable consideration and is allocated based on the estimated standalone selling prices developed using industry information and other available information for similar services. A constraining estimate of variable consideration exists related to the potential for management fees to be returned if a policy were to be cancelled mid-term. Management fees are returned to the Exchange when policyholders cancel their insurance coverage mid-term and premiums are refunded to them. The constraining estimate is determined using the expected value method, based on both historical and current information. The estimated transaction price, as reduced by the constraint, reflects consideration expected for performance of our services. We update the transaction price and the related allocation at least annually based upon the most recent information available or more frequently if there have been significant changes in any components considered in the transaction price. The first performance obligation is to provide policy issuance and renewal services that result in executed insurance policies between the Exchange or one of its insurance subsidiaries and the subscriber (policyholder). The subscriber (policyholder) receives economic benefits when substantially all the policy issuance or renewal services are complete and an insurance policy is issued or renewed by the Exchange or one of its insurance subsidiaries. It is at the time of policy issuance or renewal that the allocated portion of revenue is recognized. Consistent with its legal structure as a reciprocal insurer, the Exchange does not have any employees or officers. Therefore, it enters into contractual relationships by and through the subscribers' attorney-in-fact. Indemnity serves as the attorney-in-fact on behalf of the subscribers at the Exchange with respect to its administrative services as enumerated in the subscriber's agreement. The Exchange's insurance subsidiaries also utilize Indemnity for these services in accordance with the service agreements between each of the subsidiaries and Indemnity. Collectively, these services represent a second performance obligation under the subscriber’s agreement and the service agreements. The revenue allocated to this performance obligation is recognized over a four-year period representing the time over which these services are provided. The portion of revenue not yet earned is recorded as a contract liability in the Consolidated Statements of Financial Position. The administrative services expenses we incur and the related reimbursements we receive are recorded gross in the Consolidated Statements of Operations. Indemnity records a receivable from the Exchange for management fee revenue when the premium is written or assumed from affiliates by the Exchange. Indemnity collects the management fee from the Exchange when the Exchange collects the premiums from the subscribers (policyholders). As the Exchange issues policies almost exclusively with annual terms, cash collections generally occur within one year.
Earnings per share	Class A and Class B basic earnings per share and Class B diluted earnings per share are calculated under the two-class method. The two-class method allocates earnings to each class of stock based upon its dividend rights. Class B shares are convertible into Class A shares at a conversion ratio of 2,400 to 1. See Note 11, "Capital Stock". Class A diluted earnings per share is calculated under the if-converted method, which reflects the conversion of Class B shares to Class A shares. Diluted earnings per share calculations include the dilutive effect of assumed issuance of stock-based awards under compensation plans that have the option to be paid in stock using the treasury stock method.
Financial instruments carried at fair value	Financial instruments carried at fair value Our available-for-sale and equity securities are recorded at fair value, which is the price that would be received to sell the asset in an orderly transaction between willing market participants as of the measurement date. Valuation techniques used to derive the fair value of our available-for-sale and equity securities are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources. Unobservable inputs reflect our own assumptions regarding fair market value for these securities. Financial instruments are categorized based upon the following characteristics or inputs to the valuation techniques: •Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. •Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. •Level 3 – Unobservable inputs for the asset or liability. Estimates of fair values for our investment portfolio are obtained primarily from a nationally recognized pricing service. Our Level 1 securities are valued using an exchange traded price provided by the pricing service. Pricing service valuations for Level 2 securities include multiple verifiable, observable inputs including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. Pricing service valuations for Level 3 securities are based upon proprietary models and are used when observable inputs are not available or in illiquid markets. Although virtually all of our prices are obtained from third party sources, we also perform internal pricing reviews, including evaluating the methodology and inputs used to ensure that we determine the proper classification level of the financial instrument and reviewing securities with price changes that vary significantly from current market conditions or independent price sources. Price variances are investigated and corroborated by market data and transaction volumes. We have reviewed the pricing methodologies of our pricing service as well as other observable inputs and believe that the prices adequately consider market activity in determining fair value. In limited circumstances we adjust the price received from the pricing service when, in our judgment, a better reflection of fair value is available based upon corroborating information and our knowledge and monitoring of market conditions such as a disparity in price of comparable securities and/or non-binding broker quotes. In other circumstances, certain securities are internally priced because prices are not provided by the pricing service. When a price from the pricing service is not available, values are determined by obtaining broker/dealer quotes and/or market comparables. When available, we obtain multiple quotes for the same security. The ultimate value for these securities is determined based upon our best estimate of fair value using corroborating market information. As of March 31, 2025, nearly all of our available-for-sale and equity securities were priced using a third party pricing service.
Fair value of financial instruments, transfers between levels	We review the fair value hierarchy classifications each reporting period. Transfers between hierarchy levels may occur due to changes in available market observable inputs.
Investments	The below securities have been evaluated for credit impairment using criteria described within Note 2, "Significant Accounting Policies, of Notes to Consolidated Financial Statements" included in our Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the SEC on February 27, 2025. The gross unrealized losses are primarily attributable to changes in interest rates and are not deemed to be credit-related. We do not have the intent to sell these securities and it is more likely than not that we would not be required to sell these securities before the anticipated recovery of the amortized cost basis.
Commitments and contingencies	We are involved in litigation arising in the ordinary course of conducting business. In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated. When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss. To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations or cash flows. Legal fees are expensed as incurred. We believe that our accruals for legal proceedings are appropriate and, individually and in the aggregate, are not expected to be material to our consolidated financial condition, results of operations or cash flows. We review all litigation on an ongoing basis when making accrual and disclosure decisions. For certain legal proceedings, we cannot reasonably estimate losses or a range of loss, if any, particularly for proceedings that are in their early stages of development or where the plaintiffs seek indeterminate damages. Various factors, including, but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. In the event that a legal proceeding results in a substantial judgment against, or settlement by, us, there can be no assurance that any resulting liability or financial commitment would not have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X, and include the accounts of Indemnity and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. For further information, refer to the consolidated financial statements and footnotes included in our Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission ("SEC") on February 27, 2025.

Use of estimates

The preparation of financial statements in conformity with GAAP requires us 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recently adopted and issued accounting standards and disclosure rules

Recently adopted accounting standards

We adopted Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures", effective with the annual reporting period ending December 31, 2024. We applied the guidance retrospectively to prior periods presented in the consolidated financial statements based on the significant segment expense categories identified and disclosed in the period of adoption. As an entity with a single reportable segment, we disclose significant segment expenses that are regularly provided to our chief operating decision maker and included within each reported period of profit or loss, and all applicable disclosures required by Topic 280. The adoption of this guidance had no impact on our consolidated financial statements. The additional disclosures required by this guidance have been included in Note 4, "Segment Information".

Recently issued accounting standards and disclosure rules

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures", which requires entities to disclose specific categories in an effective tax rate reconciliation, additional information for reconciling items that meet a quantitative threshold, and certain information about income taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments can be applied on either a prospective or retrospective basis. We plan to adopt the standard in our consolidated financial statements for the year ending December 31, 2025, and we expect the standard will impact certain of our income tax disclosures.

In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules under SEC Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", requiring registrants to disclose certain climate-related information in registration statements and annual reports. The final rules include disclosure of climate-related risks that are reasonably likely to have a material impact on a registrant’s business, results of operations or financial condition. Disclosures related to significant effects of severe weather events and other natural conditions and amounts related to carbon offsets and renewable energy credits or certificates are required in the financial statements in certain circumstances. Disclosure requirements will phase in for fiscal years beginning in 2025 and be applied prospectively upon adoption. On April 4, 2024, the SEC issued a voluntary stay on its final rules until legal challenges to the rules are addressed, and on March 27, 2025, the SEC voted to end its defense of the rules and withdrew from the litigation. We continue to monitor the status of these rules pending the court's ultimate decision.

In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses", which requires entities to disclose disaggregated information about certain income statement expense line items. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments can be applied on either a prospective or retrospective basis. This will have no impact on our consolidated financial statements, and we are currently evaluating the impact of adoption on our disclosures.

Earnings per share

Class A and Class B basic earnings per share and Class B diluted earnings per share are calculated under the two-class method. The two-class method allocates earnings to each class of stock based upon its dividend rights. Class B shares are convertible into Class A shares at a conversion ratio of 2,400 to 1. See Note 11, "Capital Stock".

Class A diluted earnings per share is calculated under the if-converted method, which reflects the conversion of Class B shares to Class A shares. Diluted earnings per share calculations include the dilutive effect of assumed issuance of stock-based awards under compensation plans that have the option to be paid in stock using the treasury stock method.

Financial instruments carried at fair value

Our available-for-sale and equity securities are recorded at fair value, which is the price that would be received to sell the asset in an orderly transaction between willing market participants as of the measurement date.

Estimates of fair values for our investment portfolio are obtained primarily from a nationally recognized pricing service. Our Level 1 securities are valued using an exchange traded price provided by the pricing service.

As of March 31, 2025, nearly all of our available-for-sale and equity securities were priced using a third party pricing service.

Fair value of financial instruments, transfers between levels

We review the fair value hierarchy classifications each reporting period. Transfers between hierarchy levels may occur due to changes in available market observable inputs.

Investments

The below securities have been evaluated for credit impairment using criteria described within Note 2, "Significant Accounting Policies, of Notes to Consolidated Financial Statements" included in our Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the SEC on February 27, 2025.

In accordance with current accounting standards for loss contingencies and based upon information currently known to us, we establish reserves for litigation when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss or range of loss can be reasonably estimated. When no amount within the range of loss is a better estimate than any other amount, we accrue the minimum amount of the estimable loss. To the extent that such litigation against us may have an exposure to a loss in excess of the amount we have accrued, we believe that such excess would not be material to our consolidated financial condition, results of operations or cash flows.
