Nature of Operations

Nature of Operations	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Erie Indemnity Company ("Indemnity", "we", "us", "our") is a publicly held Pennsylvania business corporation that has since its incorporation in 1925 served as the attorney-in-fact for the subscribers (policyholders) at the Erie Insurance Exchange ("Exchange"). The Exchange, which also commenced business in 1925, is a Pennsylvania-domiciled reciprocal insurer that writes property and casualty insurance. Our primary function as attorney-in-fact is to perform policy issuance and renewal services on behalf of the subscribers at the Exchange. We also act as attorney-in-fact on behalf of the subscribers at the Exchange with respect to all claims handling and investment management services, as well as the service provider for all claims handling, life insurance and investment management services for the Exchange's insurance subsidiaries, collectively referred to as "administrative services". Acting as attorney-in-fact in these two capacities is done in accordance with a subscriber's agreement (a limited power of attorney) executed individually by each subscriber (policyholder), which appoints Indemnity as each subscriber's attorney-in-fact to transact certain business on their behalf. In accordance with the subscriber's agreement for acting as attorney-in-fact in these two capacities, we retain a management fee calculated as a percentage of the direct and affiliated assumed premiums written by the Exchange. The policy issuance and renewal services we provide on behalf of the subscribers at the Exchange are related to the sales, underwriting and issuance of policies. The sales related services we provide include agent compensation and certain sales and advertising support services. Agent compensation includes scheduled commissions to agents based upon premiums written as well as incentive compensation, which is earned by achieving targeted measures. The underwriting services we provide include underwriting and policy processing. The remaining services we provide include customer service and administrative support. We also provide information technology services that support all the functions listed above. Included in these expenses are allocations of costs for departments that support these policy issuance and renewal functions. 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. Claims handling services include costs incurred in the claims process, including the adjustment, investigation, defense, recording and payment functions. Life insurance management services include costs incurred in the management and processing of life insurance business. Investment management services are related to investment trading activity, accounting and all other functions attributable to the investment of funds. Included in these expenses are allocations of costs for departments that support these administrative functions. The subscriber's agreement and service agreements provide for reimbursement of amounts incurred for these services to Indemnity. Reimbursements are settled at cost. State insurance regulations require that intercompany service agreements and any material amendments be approved in advance by the state insurance department. Our results of operations are tied to the growth and financial condition of the Exchange. If any events occurred that impaired the Exchange’s ability to grow or sustain its financial condition, including but not limited to reduced financial strength ratings, disruption in the independent agency relationships, significant catastrophe losses or products not meeting customer demands, the Exchange could find it more difficult to retain its existing business and attract new business. A decline in the business of the Exchange almost certainly could have as a consequence a decline in the total premiums paid and a correspondingly adverse effect on the amount of the management fees we receive. We also have an exposure to a concentration of credit risk related to the unsecured receivables due from the Exchange for net management fee and other reimbursements. See Note 12, "Concentrations of Credit Risk".

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of presentation The accompanying unaudited 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. 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 six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to the financial statements and footnotes included in our Form 10-K for the year ended December 31, 2023 as filed with the Securities and Exchange Commission ("SEC") on February 26, 2024. 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 issued accounting standards and disclosure rules In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" , which requires entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported period of profit or loss, and requires entities with a single reporting segment to provide all disclosures required by Topic 280. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The update is required to be applied retrospectively to prior periods presented in the financial statements, based on the significant segment expense categories identified and disclosed in the period of adoption. This will have no impact on our financial statements. We are currently evaluating the impact of adoption on our disclosures. In December 2023, the 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. This will have no impact on our financial statements. We are currently evaluating the impact of adoption on our disclosures. In March 2024, the 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 determined to voluntarily stay the final rules pending ongoing litigation. We are currently evaluating the impact of adoption on our disclosures. Other assets Other assets primarily include limited partnership investments, other loans receivable, held-to-maturity securities, operating lease assets and other long-term prepaid assets. Limited partnership investments are recorded using the equity method of accounting. Other loans receivable include loans issued to fund real estate development projects supporting revitalization efforts in our community. The loans are carried at unpaid principal balance, including any paid-in-kind interest capitalized as additional principal, if applicable, net of a current expected credit loss allowance. Any current portion of other loans receivable is recorded in prepaid expenses and other current assets. Held-to-maturity securities are carried at amortized cost, net of a current expected credit loss allowance. The allowances are calculated using the estimated value of, and priority rights to, collateral in the event of default or external loss rates based on comparable losses, and considers current market conditions and forecasted information. Changes to the allowances are recognized in earnings as adjustments to net impairment recoveries (losses) or other income (expense) depending on the nature of the asset. Interest on other loans receivable and held-to-maturity securities is recorded primarily in investment income as earned. Securities lending Beginning in May 2024 we entered into securities lending transactions, managed by a third-party banking institution, whereby securities are loaned to unaffiliated financial institutions for short periods of time. The securities lending activity is accounted for as a secured borrowing and therefore the securities loaned, primarily fixed maturity securities, are carried as invested assets on our Statement of Financial Position, while the obligation to return the collateral is recorded as a current liability. The cash collateral received at the inception of the loan is reinvested and the related income is recognized in net investment income. Noncash collateral is not recorded in the Statements of Financial Position, as we do not have the right to sell, pledge, or otherwise reinvest the noncash collateral. Collateral received can only be accessed by us if the institution borrowing the securities is in default. The collateral is required to equal a minimum of 102% of the estimated fair value of the securities loaned, and maintained at a level greater than or equal to 100% for the duration of the loan. We monitor the ratio of the collateral held to the estimated fair value of the securities loaned on a daily basis and obtain additional collateral as necessary. A securities lending transaction may be terminated at any time by the borrower or the lender. If terminated, we would repay our securities lending obligations from the sale of reinvested collateral or the proceeds of sales from our investment portfolio, which includes liquid securities.

Revenue from Contract with Customer [Abstract]
Revenue	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 Statements of Financial Position. During the three and six months ended June 30, 2024, we recognized revenue of $11.9 million and $26.9 million, respectively, that was included in the contract liability balance as of December 31, 2023. During the three and six months ended June 30, 2023, we recognized revenue of $10.5 million and $23.8 million, respectively, that was included in the contract liability balance as of December 31, 2022. The administrative services expenses we incur and the related reimbursements we receive are recorded gross in the 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 with annual terms only, cash collections generally occur within one year. The following table disaggregates revenue by our two performance obligations: Three months ended June 30, Six months ended June 30, (in thousands) 2024 2023 2024 2023 Management fee revenue - policy issuance and renewal services $ 760,886 $ 633,339 $ 1,426,572 $ 1,191,429 Management fee revenue - administrative services 17,051 15,636 33,985 30,825 Administrative services reimbursement revenue 206,028 184,466 397,595 357,293 Total revenue from administrative services $ 223,079 $ 200,102 $ 431,580 $ 388,118

Earnings Per Share [Abstract]
Earnings Per Share	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 10, "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. A reconciliation of the numerators and denominators used in the basic and diluted per-share computations is presented as follows for each class of common stock: Three months ended June 30, 2024 2023 (dollars in thousands, except per share data) Allocated net income (numerator) Weighted shares (denominator) Per-share amount Allocated net income (numerator) Weighted shares (denominator) Per-share amount Class A – Basic EPS: Income available to Class A stockholders $ 162,561 46,189,042 $ 3.52 $ 116,887 46,189,026 $ 2.53 Dilutive effect of stock-based awards 0 15,457 — 0 10,148 — Assumed conversion of Class B shares 1,342 6,100,800 — 965 6,100,800 — Class A – Diluted EPS: Income available to Class A stockholders on Class A equivalent shares $ 163,903 52,305,299 $ 3.13 $ 117,852 52,299,974 $ 2.25 Class B – Basic EPS: Income available to Class B stockholders $ 1,342 2,542 $ 528 $ 965 2,542 $ 380 Class B – Diluted EPS: Income available to Class B stockholders $ 1,342 2,542 $ 528 $ 965 2,542 $ 380 Six months ended June 30, 2024 2023 (dollars in thousands, except per share data) Allocated net income (numerator) Weighted shares (denominator) Per-share amount Allocated net income (numerator) Weighted shares (denominator) Per-share amount Class A – Basic EPS: Income available to Class A stockholders $ 286,093 46,189,028 $ 6.19 $ 202,422 46,188,923 $ 4.38 Dilutive effect of stock-based awards 0 13,723 — 0 8,575 — Assumed conversion of Class B shares 2,362 6,100,800 — 1,671 6,100,800 — Class A – Diluted EPS: Income available to Class A stockholders on Class A equivalent shares $ 288,455 52,303,551 $ 5.52 $ 204,093 52,298,298 $ 3.90 Class B – Basic EPS: Income available to Class B stockholders $ 2,362 2,542 $ 929 $ 1,671 2,542 $ 657 Class B – Diluted EPS: Income available to Class B stockholders $ 2,361 2,542 $ 929 $ 1,671 2,542 $ 657

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	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 June 30, 2024, nearly all of our available-for-sale and equity securities were priced using a third party pricing service.

There was no collateral that we are not permitted to sell or repledge and there are no securities lending transactions that extend beyond one year from the reporting date. If we have to return cash collateral on short notice, we may have difficulty selling investments in a timely manner, be forced to sell them for less than we otherwise would have been able to realize, or both. In addition, in the event of such forced sale, for securities in an unrealized loss position, realized losses would be incurred on securities sold and impairments would be incurred, if there is a need to sell securities prior to recovery, which may negatively impact our financial condition.

Postretirement Benefits

Retirement Benefits [Abstract]
Postretirement Benefits	Postretirement Benefits Pension plans Our pension plans consist of a noncontributory defined benefit pension plan covering substantially all employees and an unfunded supplemental employee retirement plan ("SERP") for certain members of executive and senior management. The pension plan provides benefits to covered individuals satisfying certain age and service requirements. The defined benefit pension plan and SERP each provide benefits through a final average earnings formula. Although we are the sponsor of these postretirement plans and record the funded status of these plans, there are reimbursements between us and the Exchange and its subsidiaries for their allocated share of pension income or cost. These reimbursements represent pension benefits for employees performing administrative services and an allocated share of plan (income) cost for employees in departments that support the administrative functions. For the six months ended June 30, 2024, we reimbursed the Exchange and its subsidiaries for approximately 60% of the annual defined benefit pension income and 34% of the annual SERP income. For our funded pension plan, amounts are settled in cash for the portion of pension (income) cost allocated to the Exchange and its subsidiaries. For our unfunded SERP, we pay the obligations when due and amounts are settled in cash between entities when there is a payout. Our defined benefit pension plan funding policy is generally to contribute an amount equal to the greater of the target normal cost for the plan year, or the amount necessary to fund the plan to 100%. Accordingly, we made a $33 million contribution in January 2024. The funded pension plan net benefit asset is presented separately from the unfunded plan as a non-current asset on our Statements of Financial Position. Pension plan income includes the following components: Three months ended June 30, Six months ended June 30, (in thousands) 2024 2023 2024 2023 Service cost for benefits earned $ 8,641 $ 7,191 $ 17,292 $ 14,382 Interest cost on benefit obligation 13,163 12,548 26,308 25,096 Expected return on plan assets (20,198) (17,217) (40,396) (34,435) Prior service cost amortization 397 361 786 723 Net actuarial gain amortization (1,734) (3,832) (3,485) (7,665) Settlement gain (1) (1,030) — (1,279) — Pension plan income (2) $ (761) $ (949) $ (774) $ (1,899) (1) Settlement accounting was required due to lump sum payments made under the SERP to three former officers in 2024.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We have an agreement with a bank for an agent loan participation program. The maximum amount of loans to be funded through this program is $150 million. We have committed to fund a minimum of 30% of each loan executed through this program. As of June 30, 2024, outstanding loans executed under this agreement totaled $55.9 million, of which our portion of the loans is $18.8 million. Additionally, we have agreed to guarantee a portion of the funding provided by the other participants in the program in the event of default. As of June 30, 2024, our maximum potential amount of future payments on the guaranteed portion is $7.5 million. All loan payments under the participation program are current as of June 30, 2024. We also have contingent obligations for guarantees related to certain real estate development projects supporting revitalization efforts in our community. As of June 30, 2024, our maximum potential obligation related to guarantees is $9.3 million. 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 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 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 financial condition, results of operations or cash flows.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited 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. 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 six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to the financial statements and footnotes included in our Form 10-K for the year ended December 31, 2023 as filed with the Securities and Exchange Commission ("SEC") on February 26, 2024.
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 issued accounting standards and disclosure rules	Recently issued accounting standards and disclosure rules In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" , which requires entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported period of profit or loss, and requires entities with a single reporting segment to provide all disclosures required by Topic 280. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The update is required to be applied retrospectively to prior periods presented in the financial statements, based on the significant segment expense categories identified and disclosed in the period of adoption. This will have no impact on our financial statements. We are currently evaluating the impact of adoption on our disclosures. In December 2023, the 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. This will have no impact on our financial statements. We are currently evaluating the impact of adoption on our disclosures. In March 2024, the 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 determined to voluntarily stay the final rules pending ongoing litigation. We are currently evaluating the impact of adoption on our disclosures.
Other assets	Other assets
Securities lending	Securities lending Beginning in May 2024 we entered into securities lending transactions, managed by a third-party banking institution, whereby securities are loaned to unaffiliated financial institutions for short periods of time. The securities lending activity is accounted for as a secured borrowing and therefore the securities loaned, primarily fixed maturity securities, are carried as invested assets on our Statement of Financial Position, while the obligation to return the collateral is recorded as a current liability. The cash collateral received at the inception of the loan is reinvested and the related income is recognized in net investment income. Noncash collateral is not recorded in the Statements of Financial Position, as we do not have the right to sell, pledge, or otherwise reinvest the noncash collateral. Collateral received can only be accessed by us if the institution borrowing the securities is in default. The collateral is required to equal a minimum of 102% of the estimated fair value of the securities loaned, and maintained at a level greater than or equal to 100% for the duration of the loan. We monitor the ratio of the collateral held to the estimated fair value of the securities loaned on a daily basis and obtain additional collateral as necessary. A securities lending transaction may be terminated at any time by the borrower or the lender. If terminated, we would repay our securities lending obligations from the sale of reinvested collateral or the proceeds of sales from our investment portfolio, which includes liquid securities.
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. 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 with annual terms only, 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 10, "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 June 30, 2024, 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 Financial Statements" included in our Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on February 26, 2024. 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 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 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 financial condition, results of operations or cash flows.
