When we sell investments, we calculate the gain or loss realized on the sale by comparing the sales price (fair value) to the cost or adjusted/amortized cost of the security sold. We determine the cost or adjusted/amortized cost of the security sold using the specific-identification method. The following table details our realized gains (losses) by major investment category for the years ended December 31, 2023, 2022 and 2021:

Portfolio monitoring

We have a quarterly portfolio monitoring process to identify and evaluate each fixed-income security whose carrying value
may be impaired as the result of a credit loss. For each fixed-income security in an unrealized loss position, if we determine that
we intend to sell the security or that it is more likely than not that we will be required to sell the security before recovery of the
cost or amortized cost basis for reasons such as liquidity needs, contractual or regulatory requirements, the security's entire
decline in fair value is recorded in earnings.

If our management decides not to sell the fixed-income security and it is more likely than not that we will not be required to sell the fixed-income security before recovery of its amortized cost basis, we evaluate whether the decline in fair value has resulted from credit losses or other factors. This is typically indicated by a change in the rating of the security assigned by a rating agency, and any adverse conditions specifically related to the security or industry, among other factors. If the assessment indicates that a credit loss may exist, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses will be recorded in earnings. Credit loss is limited to the difference between a security's amortized cost basis and its fair value. Any additional impairment not recorded through an allowance for credit losses is recognized in other comprehensive loss.

During the year-ended December 31, 2023, we determined that none of our fixed-income securities shown in the table below that are in an unrealized loss position have declines in fair value that are reflected as a result of credit losses. Therefore, no credit loss allowance was recorded at December 31, 2023. The issuers of our debt security investments continue to make interest payments on a timely basis. We do not intend to sell, nor is it likely that we would be required to sell the debt securities before we recover our amortized cost basis. Equity securities are reported at fair value with changes in fair value recognized in the valuation of equity investments.

Fair value measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The hierarchy for inputs used in determining fair value maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Assets and liabilities recorded on our Consolidated Balance Sheets at fair value are categorized in the fair value hierarchy based on the observability of inputs to the valuation techniques as follows:

Level 1: Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that we can access.

Level 2: Assets and liabilities whose values are based on the following:
    (a) Quoted prices for similar assets or liabilities in active markets;
    (b) Quoted prices for identical or similar assets or liabilities in markets that are not active; or
(c) Valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs reflect our estimates of the assumptions that market participants would use in valuing the assets and liabilities.

We estimate the fair value of our investments using the closing prices on the last business day of the reporting period, obtained from active markets such as the NYSE, Nasdaq and NYSE American. For securities for which quoted prices in active
markets are unavailable, we use a third-party pricing service that utilizes quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs to estimate the fair value of those securities for which quoted prices are unavailable. Our estimates of fair value reflect the interest rate environment that existed as of the close of business on December 31, 2023 and 2022. Changes in interest rates subsequent to December 31, 2023 may affect the fair value of our investments.

The fair value of our fixed maturities is initially calculated by a third-party pricing service. Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of proprietary models, produce valuation information in the form of a single fair value for individual fixed income and other securities for which a fair value has been requested. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, liquidity spreads, currency rates and other information, as applicable. Credit and liquidity spreads are typically implied from completed transactions and transactions of comparable securities. Valuation service providers also use proprietary discounted cash flow models that are widely accepted in the financial services industry and similar to those used by other market participants to value the same financial information. The valuation models take into account, among other things, market observable information as of the measurement date, as described above, as well as the specific attributes of the security being valued, including its term, interest rate, credit rating, industry sector and, where applicable, collateral quality and other issue or issuer specific information. Executing valuation models effectively requires seasoned professional judgment and experience.

Any change in the estimated fair value of our fixed-income securities would impact the amount of unrealized gain or loss we have recorded, which could change the amount we have recorded for our investments and other comprehensive income (loss) on our Consolidated Balance Sheet as of December 31, 2023.

(1) Other long-term investments included in the fair value hierarchy exclude these other limited partnership interests that are measured at estimated fair value using the net asset value per share (or its equivalent) practical expedient.

    Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; this is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). There were no financial instruments measured on a non-recurring basis at December 31, 2023 and 2022.

    The carrying amounts for the following financial instrument categories approximate their fair values at December 31, 2023 and 2022, because of their short-term nature: cash and cash equivalents, accrued investment income, premiums receivable, reinsurance recoverable, reinsurance payable, other assets, and other liabilities. The carrying amount of our senior notes approximate fair value as the interest rates and terms are variable.

We are responsible for the determination of fair value and the supporting assumptions and methodologies. We have implemented a system of processes and controls designed to provide assurance that our assets and liabilities are appropriately valued. For fair values received from third parties, our processes are designed to provide assurance that the valuation methodologies and inputs are appropriate and consistently applied, the assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded.

At the end of each quarter, we determine whether we need to transfer the fair values of any securities between levels of the fair value hierarchy and, if so, we report the transfer as of the end of the quarter. During 2023, we transferred no investments between levels.

For our investments in U.S. government securities that do not have prices in active markets, agency securities, state and municipal governments, and corporate bonds, we obtain the fair values from our investment custodians, which use a third-party
valuation service. The valuation service calculates prices for our investments in the aforementioned security types on a month-end basis by using several matrix-pricing methodologies that incorporate inputs from various sources. The model the valuation service uses to price U.S. government securities and securities of states and municipalities incorporates inputs from active market makers and inter-dealer brokers. To price corporate bonds and agency securities, the valuation service calculates non-call yield spreads on all issuers, uses option-adjusted yield spreads to account for any early redemption features, and adds final spreads to the U.S. Treasury curve at 3 p.m. (ET) as of quarter end. Since the inputs the valuation service uses in its calculations are not quoted prices in active markets, but are observable inputs, they represent Level 2 inputs.

Other investments

We acquired investments in limited partnerships, recorded in the other investments line of our Consolidated Balance Sheets and these investments are currently being accounted for at fair value utilizing a net asset value per share equivalent methodology.

Restricted Cash

We are required to maintain assets on deposit with various regulatory authorities to support our insurance operations. The cash on deposit with state regulators is available to settle insurance liabilities. We also use trust funds in certain reinsurance transactions.
