Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments | (6) Fair Value of Financial Instruments Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Invested assets recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our view of market assumptions in the absence of observable market information. We classify and disclose all invested assets carried at fair value in one of the following three levels: • Level 1. Quoted prices for identical instruments in active markets. Level 1 consists of financial instruments whose value is based on quoted market prices in active markets, such as cash, cash equivalents in money market funds, exchange-traded common stocks and actively traded mutual fund investments; • Level 2. Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. Level 2 includes those financial instruments that are valued using industry-standard pricing methodologies, models or other valuation methodologies. Various inputs are considered in deriving the fair value of the underlying financial instrument, including interest rate and yield curves, credit spread, and foreign exchange rates. All significant inputs are observable, or derived from observable information in the marketplace or are supported by observable levels at which transactions are executed in the marketplace. Financial instruments in this category could include: cash equivalents and short-term investments in U.S. treasury securities; certain public and private corporate fixed-maturity and equity securities; government or agency securities; and certain mortgage- and asset-backed securities; and • Level 3. Valuations derived from valuation techniques in which one or more significant inputs are unobservable. Level 3 consists of financial instruments whose fair value is estimated based on industry-standard pricing methodologies and models using significant inputs not based on, nor corroborated by, readily available market information. Valuations for this category primarily consist of non-binding broker quotes. Financial instruments in this category could include less liquid mortgage- and asset-backed securities and equity securities. As of each reporting period, all assets and liabilities recorded at fair value are classified in their entirety based on the lowest level of input (Level 3 being the lowest in the hierarchy) that is significant to the fair value measurement. Significant levels of estimation and judgment are required to determine the fair value of certain of our investments. The factors influencing these estimations and judgments are subject to change in subsequent reporting periods. The estimated fair value and hierarchy classifications for assets and liabilities that are measured at fair value on a recurring basis were as follows:

In estimating fair value of our investments, we use a third-party pricing service for approximately all of our securities that are measured at fair value on a recurring basis. The remaining securities are primarily thinly-traded securities, such as private placements, and are valued using models based on observable inputs on public corporate spreads having similar characteristics (e.g., sector, average life and quality rating), liquidity and yield based on quality rating, average life and U.S. Treasury yields. All observable data inputs are corroborated by independent third-party data. We also corroborate pricing information provided by our third-party pricing service by performing a review of selected securities. Our review activities include: obtaining detailed information about the assumptions, inputs and methodologies used in pricing the security; documenting this information; and corroborating it by comparison to independently obtained prices and/or independently developed pricing methodologies. Furthermore, we perform internal reasonableness assessments on fair value determinations within our portfolio throughout the year and as of year-end, including pricing variance analyses and comparisons to alternative pricing sources and benchmark returns. If a fair value appears unusual relative to these assessments, we will re-examine the inputs and may challenge a fair value assessment made by the pricing service. If there is a known pricing error, we will request a reassessment by the pricing service. If the pricing service is unable to perform the reassessment on a timely basis, we will determine the appropriate price by requesting a reassessment from an alternative pricing service or other qualified source as necessary. We do not adjust quotes or prices except in a rare circumstance to resolve a known error. Because many fixed-maturity securities do not trade on a daily basis, third-party pricing services generally determine fair value using industry-standard methodologies, which vary by asset class. For corporates, governments, and agency securities, these methodologies include developing prices by incorporating available market information such as U.S. Treasury curves, benchmarking of similar securities including new issues, sector groupings, quotes from market participants and matrix pricing. Observable information is compiled and integrates relevant credit information, perceived market movements and sector news. Additionally, security prices are periodically back-tested to validate and/or refine models as conditions warrant. Market indicators and industry and economic events are also monitored as triggers to obtain additional data. For certain structured securities (such as mortgage- and asset-backed securities) with limited trading activity, third-party pricing services generally use industry-standard pricing methodologies that incorporate market information, such as index prices or discounting expected future cash flows based on underlying collateral, and quotes from market participants, to estimate fair value. If one or more of these input measures are not deemed observable for a particular security, the security will be classified as Level 3 in the fair value hierarchy. Where specific market information is unavailable for certain securities, pricing models produce estimates of fair value primarily using Level 2 inputs along with certain Level 3 inputs. These models include matrix pricing. The pricing matrix uses current U.S. Treasury rates and credit spreads received from third-party sources to estimate fair value. The credit spreads incorporate the issuer’s industry- or issuer-specific credit characteristics and the security’s time to maturity, if warranted. Remaining unpriced securities are valued using an estimate of fair value based on indicative market prices that include significant unobservable inputs not based on, nor corroborated by, market information, including the utilization of non-binding broker quotes. The roll-forward of the Level 3 assets measured at fair value on a recurring basis was as follows:
|  | Three months ended September 30, |  |  | Nine months ended September 30, (1) |

(1) Transfers of investments that enter and exit Level 3 in different quarters within the same fiscal year are not eliminated until the full year amounts are presented. We obtain independent pricing quotes based on observable inputs as of the end of the reporting period for all securities in Level 2. Those inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, market bids/offers, quoted prices for similar instruments in markets that are not active, and other relevant data. We monitor these inputs for market indicators, industry and economic events. There were no material transfers betw een Level 1 and Level 3 during the three and nine months ended September 30, 2025 and 2024.

(1) Classified as a Level 3 fair value measurement. (2) Carrying value amounts shown are net of unamortized issuance costs. (3) Classified as a Level 2 fair value measurement. The fair values of financial instruments presented above are estimates of the fair values at a specific point in time using various sources and methods, including market quotations and a complex matrix system that takes into account issuer sector, quality, and spreads in the current marketplace. Financial Instruments Recognized at Fair Value in the Balance Sheets. Estimated fair values of investments in AFS securities are principally a function of current spreads and interest rates that are corroborated by independent third-party data. Therefore, the fair values presented are indicative of amounts we could realize or settle at the respective balance sheet date. We do not necessarily intend to dispose of or liquidate such instruments prior to maturity. Trading securities and equity securities, including common and nonredeemable preferred stocks, are carried at fair value. Segregated funds in separate accounts are carried at the underlying value of the variable insurance contracts, which is fair value. The carrying amounts for cash and cash equivalents, trade receivables, accrued investment income, accounts payable, cash collateral and payables for security transactions approximate their fair values due to the short-term nature of these instruments. Consequently, such financial instruments are not included in the above table.
