Fair Value Measurements
a) Fair Values of Financial Instruments measured at fair value
ASC 825, "Disclosure About Fair Value of Financial Instruments", requires all entities to disclose the fair value of their financial instruments for both assets and liabilities recognized and not recognized within the balance sheet, and for which it is practicable to estimate fair value. The following describes the valuation techniques used by the Company to determine the fair value of financial instruments measured at fair value held at December 31, 2024 and 2023.
U.S. government and U.S. agency bonds — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, Federal National Mortgage Association and the Federal Farm Credit Banks Funding Corporation. The fair values of U.S. treasury bonds are based on quoted market prices in active markets, and are included in the Level 1 fair value hierarchy. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. agency bonds are included in the Level 2 fair value hierarchy.
Non-U.S. government bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government bonds are observable market inputs, the fair values of non-U.S. government and bonds are included in the Level 2 fair value hierarchy.
Collateralized loan obligations ("CLO") - These asset backed securities are originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CLO are observable market inputs, the fair values are included in the Level 2 fair value hierarchy.
Commercial mortgage-backed securities ("CMBS") - These asset backed securities are originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS are observable market inputs, the fair values are included in the Level 2 fair value hierarchy.
Corporate and municipal bonds — Bonds issued by corporations, U.S. state and municipality entities or agencies. that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The credit spreads are sourced from broker/dealers, trade prices and new issue market. Where pricing is unavailable from pricing services, custodian pricing or non-binding quotes are obtained from broker-dealers to estimate fair values. As significant inputs used to price corporate and municipal bonds are observable market inputs, fair values are included in the Level 2 fair value hierarchy.
Equity securities - Equity securities include publicly traded common stocks, and privately held common and preferred stocks. The fair value of publicly traded common stocks is primarily priced by pricing services, reflecting the closing price quoted for the final trading day of the period. These investments are carried at fair value using observable market pricing data and is included in the Level 1 fair value hierarchy. Any unrealized gains or losses on the investment is recorded in net income in the reporting period in which it occurs. The privately held common and preferred stocks are valued using significant inputs that are unobservable where there is little or no market activity. Unadjusted third party pricing sources or management's assumptions and internal valuation models may be used to determine the fair values, therefore, these investments are classified as Level 3 in the fair value hierarchy.
Other investments — These investments are comprised of the following types of investments:
Privately held investments: These are direct equity investments in common and preferred shares of privately held entities. The fair values are estimated using quarterly financial statements and/or recent private market transactions and thus included under Level 3 of the fair value hierarchy due to unobservable market data used for valuation.
Private credit funds: These are privately held equity investments in common stock of entities that lend money valued using the most recently available or quarterly NAV statements as provided by the external fund manager or third-party administrator and therefore measured using the NAV as a practical expedient.
Private equity funds: These are comprised of private equity funds, private equity co-investments with sponsoring entities and investments in real estate limited partnerships and joint ventures. The fair value is estimated based on the most recently available NAV as advised by the external fund manager or third-party administrator. The fair values are therefore measured using the NAV as a practical expedient.
Derivative Instruments - The Company entered into a retroactive reinsurance contract that is accounted for as a derivative. This reinsurance contract provides indemnification to an insured or cedant as a result of a change in a variable as opposed to an identifiable insurable event. The Company considers this contract to be part of its underwriting operations. This derivative is initially valued at cost which approximates fair value. In subsequent measurement periods, the fair value of this derivative is determined using internally developed discounted cash flow models using appropriate discount rates. The selection of an appropriate discount rate is judgmental and is the most significant unobservable input used in the valuation of this derivative.
5. Fair Value Measurements (continued)
The fair value changes in the underwriting-related derivative instrument are included in other insurance revenue (expense), net. The derivative liability on retroactive reinsurance is presented as part of accrued expenses and other liabilities. A significant increase (decrease) in this input in isolation may result in a significantly lower (higher) fair value measurement for the derivative contract. As the significant inputs used to price the derivative are unobservable, the fair values of this contract is classified as Level 3 in the fair value hierarchy.
b) Fair Value Hierarchy
The Company’s estimates of fair value for its financial assets and financial liabilities are based on the framework established in ASC 820. The framework is based on the inputs used in valuation and gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuation methodology whenever available. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active trading markets and the lowest priority to unobservable inputs that reflect significant market assumptions.
At December 31, 2024 and 2023, the Company classified its financial instruments measured at fair value on a recurring basis in the following valuation hierarchy:

5. Fair Value Measurements (continued)
The Company utilizes the Pricing Service to assist in determining the fair value of its investments; however, management is ultimately responsible for all fair values presented in the Company’s financial statements. This includes responsibility for monitoring the fair value process, ensuring objective and reliable valuation practices, and pricing of assets and liabilities and use of pricing sources. The Company analyzes and reviews the information and prices received from the Pricing Service to ensure that the prices provided represent a reasonable estimate of fair value.
The Pricing Service was utilized to estimate fair value measurements for 100.0% and 97.9% of our fixed maturities at December 31, 2024 and 2023, respectively. The Pricing Service utilizes market quotations for fixed maturity securities that have quoted market prices in active markets. Since fixed maturities other than U.S. treasury bonds generally do not trade actively on a daily basis, the Pricing Service prepares estimates of fair value measurements using relevant market data, benchmark curves, sector groupings and matrix pricing and these have been classified as Level 2 within the fair value hierarchy.
At December 31, 2024 and 2023, approximately 0.0% and 2.1%, respectively, of our fixed maturities were valued using the market approach. At December 31, 2024, no securities (2023 - one security or $5,382) in our fixed maturity investment portfolio currently was priced using a non-binding quotation from a broker and/or custodian as opposed to the Pricing Service. At December 31, 2024 and 2023, the Company has not adjusted any pricing provided to it based on the review performed by its investment managers.
There was one corporate bond transferred from Level 3 to Level 2 for the year ended December 31, 2024 due to its sale; this security was valued at $5,382 and was transferred to Level 3 from Level 2 in the fair value hierarchy for the year ended December 31, 2023 due to a lack of active quotes. There was also a private equity investment valued at $24,765 transferred to Level 3 from the NAV practical expedient in the fair value hierarchy for the year ended December 31, 2023.
c) Level 3 Financial Instruments
At December 31, 2024, the Company holds Level 3 financial instruments which include privately held investments of $48,001 (2023 - $46,656) and an underwriting-related derivative liability of $3,984 (2023 - $3,984) on a reinsurance contract written by GLS which is included in accrued expenses and other liabilities.
The fair value of privately held equity securities are estimated using quarterly unaudited capital or financial statements provided by the investee or recent private market transactions, where applicable. Any changes to the financial information provided by the investee could result in a significantly higher or lower valuation at the reporting date. The fair value of underwriting-related derivative instruments is determined using a discounted cash flow model in which the Company examines current market conditions, historical results as well as contract specific information that may impact future cash flows in order to assess the reasonableness of inputs used in the valuation model. Due to significant unobservable inputs in these valuations, the Company classifies the fair values as Level 3 within the fair value hierarchy.
The following table provides a summary of quantitative information regarding the significant unobservable inputs used in determining the fair value of other investments measured at fair value on a recurring basis under the Level 3 classification at December 31, 2024:

d) Financial Instruments Disclosed, But Not Carried, at Fair Value
The fair value of financial instruments accounting guidance also applies to financial instruments disclosed, but not carried at fair value, except for certain financial instruments related to insurance contracts.
At December 31, 2024, the carrying values of cash equivalents (including restricted amounts), accrued investment income, reinsurance balances receivable and certain other assets and liabilities approximate fair values due to their inherent short duration. As these financial instruments are not actively traded, the fair values of these financial instruments are classified as Level 2 in the fair value hierarchy.
At December 31, 2024, the carrying value of the loan to related party approximated fair value. The fair value of this loan is primarily determined by estimating expected future cash flows and discounting them using current interest rates for similar loans with similar credit risk. As the loan to related party is not actively traded, its fair value is classified as Level 3 in the fair value hierarchy.
The investments made by direct lending entities are carried at cost less an allowance for expected credit losses, with any indication of credit loss recognized in net income (loss) when determined. The net carrying value of these investments approximates their fair value at December 31, 2024. The fair value estimates of these investments are not based on observable market data and therefore are classified as Level 3 in the fair value hierarchy.
For equity securities and other investments without a readily determinable fair value, the measurement alternative was elected to report the qualifying investment at cost, less impairment if any, plus or minus observable price changes in orderly transactions for an identical or similar investment of the same issuer.
The fair values of the Company's outstanding Senior Notes for the respective periods (as defined in Note 7 — Long-Term Debt) are based on indicative market pricing obtained from a third-party pricing service which uses observable market inputs, and therefore the fair values of these liabilities are classified as Level 2 in the fair value hierarchy.
The following table presents the respective carrying value and fair value for the Company's outstanding Senior Notes as at December 31, 2024 and 2023:

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
