The Company regularly performs various analytical valuation procedures with respect to its investments, including reviewing each available for sale debt security in an unrealized loss position to assess whether the decline in fair value below amortized cost basis has resulted from a credit loss or other factors. In assessing whether a credit loss exists, the Company compares the present value of the cash flows expected to be collected from the security to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis of the security, a credit loss exists and an allowance for expected credit losses is recorded. Subsequent changes in the allowances are recorded in the period of change as either credit loss expense or reversal of credit loss expense. Any impairments related to factors other than credit losses and the intent to sell are recorded through other comprehensive income, net of taxes. For fixed maturities, the factors considered in reaching the conclusion that a credit loss exists include, among others, whether: (1) the extent to which the fair value is less than the amortized cost basis; (2) the issuer is in financial distress; (3) the investment is secured; (4) a significant credit rating action occurred; (5) scheduled interest payments were delayed or missed; (6) changes in laws or regulations have affected an issuer or industry; (7) the investment has an unrealized loss and was identified by the Company’s investment manager as an investment to be sold before recovery or maturity; (8) the investment failed cash flow projection testing to determine if anticipated principal and interest payments will be realized; and (9) changes in US Treasury rates and/or credit spreads since original purchase to identify whether the unrealized loss is simply due to interest rate movement. According to accounting guidance for debt securities in an unrealized loss position, the Company is required to assess whether it has the intent to sell the debt security or more likely than not will be required to sell the debt security before the anticipated recovery. If either of these conditions is met, any allowance for expected credit losses is written off and the amortized cost basis is written down to the fair value of the fixed maturity security with any incremental impairment reported in earnings. That new amortized cost basis shall not be adjusted for subsequent recoveries in fair value. The Company elected the practical expedient to exclude accrued interest from both the fair value and the amortized cost basis of the available for sale debt securities for the purposes of identifying and measuring an impairment and to not measure an allowance for expected credit losses for accrued interest receivables. Accrued interest receivable is written off through net realized investment gains (losses) at the time the issuer of the bond defaults or is expected to default on payment. The Company made an accounting policy election to present the accrued interest receivable balance with other assets on the Company’s consolidated statements of financial position. Accrued interest receivable related to fixed maturities was $6.5 million and $8.4 million as of September 30, 2023 and December 31, 2022, respectively. The following is a description, by asset type, of the methodology and significant inputs that the Company used to measure the amount of credit loss recognized in earnings, if any: U.S. treasuries – As of September 30, 2023, gross unrealized losses related to U.S. treasuries were $6.671 million. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, macroeconomic and market analysis is conducted in evaluating these securities. Consideration is given to the interest rate environment, duration and yield curve management of the portfolio, sector allocation and security selection. Based on the analysis performed, the Company did not recognize a credit loss on U.S. treasuries during the period. Obligations of states and political subdivisions – As of September 30, 2023, gross unrealized losses related to obligations of states and political subdivisions were $1.760 million. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, elements that may influence the performance of the municipal bond market are considered in evaluating these securities such as investor expectations, supply and demand patterns, and current versus historical yield and spread relationships. The analysis relies on the output of fixed income credit analysts, as well as dedicated municipal bond analysts who perform extensive in-house fundamental analysis on each issuer, regardless of their rating by the major agencies. Based on the analysis performed, the Company did not recognize a credit loss on obligations of states and political subdivisions during the period. Mortgage-backed securities (“MBS”) – As of September 30, 2023, gross unrealized losses related to mortgage-backed securities were $7.487 million. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, mortgage-backed securities are modeled to project principal losses under downside, base, and upside scenarios for the economy and home prices. The primary assumption that drives the security and loan level modeling is the Home Price Index (“HPI”) projection. These forecasts incorporate not just national macro-economic trends, but also regional impacts to arrive at the most granular and accurate projections. These assumptions are incorporated into the model as a basis to generate delinquency probabilities, default curves, loss severity curves, and voluntary prepayment curves at the loan level within each deal. The model utilizes HPI-adjusted current loan to value, payment history, loan terms, loan modification history, and borrower characteristics as inputs to generate expected cash flows and principal loss for each bond under various scenarios. Based on the analysis performed, the Company did not recognize a credit loss on mortgage-backed securities during the period. Asset backed securities (“ABS”) - As of September 30, 2023, gross unrealized losses related to asset backed securities were $7.124 million. The weighted average credit enhancement for the Company’s asset backed portfolio is 35.9. This represents the percentage of pool losses that can occur before an asset backed security will incur its first dollar of principal losses. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, every ABS transaction is analyzed on a stand-alone basis. This analysis involves a thorough review of the collateral, prepayment, and structural risk in each transaction. Additionally, the analysis includes an in-depth credit analysis of the originator and servicer of the collateral. The analysis projects an expected loss for a deal given a set of assumptions specific to the asset type. These assumptions are used to calculate at what level of losses the deal will incur its first dollar of principal loss. The major assumptions used to calculate this ratio are loss severities, recovery lags, and no advances on principal and interest. Based on the analysis performed, the Company did not recognize a credit loss on asset backed securities during the period. Commercial mortgage-backed securities (“CMBS”) - As of September 30, 2023, gross unrealized losses related to the CMBS portfolio were $6.628 million. The weighted average credit enhancement for the Company’s CMBS portfolio is 47.1. This represents the percentage of pool losses that can occur before a commercial mortgage-backed security will incur its first dollar of principal loss. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, a loan level analysis is utilized where every underlying CMBS loan is re-underwritten based on a set of assumptions reflecting expectations for the future path of the economy. Each loan is analyzed over time using a series of tests to determine if a credit event will occur during the life of the loan. Inherent in this process are several economic scenarios and their corresponding rent/vacancy and capital market states. The five primary credit events that frame the analysis include loan modifications, term default, balloon default, extension, and ability to pay off at balloon. The resulting output is the expected loss adjusted cash flows for each bond under the base case and distressed scenarios. Based on the analysis performed, the Company did not recognize a credit loss on commercial mortgage-backed securities during the period. Corporate bonds - As of September 30, 2023, gross unrealized losses related to corporate bonds were $11.351 million. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, analysis for this asset class includes maintaining detailed financial models that include a projection of each issuer’s future financial performance, including prospective debt servicing capabilities, capital structure composition, and the value of the collateral. The analysis incorporates the macroeconomic environment, industry conditions in which the issuer operates, the issuer’s current competitive position, its vulnerability to changes in the competitive and regulatory environment, issuer liquidity, issuer commitment to bondholders, issuer creditworthiness, and asset protection. Part of the process also includes running downside scenarios to evaluate the expected likelihood of default as well as potential losses in the event of default. Based on the analysis performed, the Company did not recognize a credit loss on corporate bonds during the period. Foreign bonds – As of September 30, 2023, gross unrealized losses related to foreign bonds were $6.236 million. To assess whether the decline in fair value below amortized cost has resulted from a credit loss or other factors, detailed financial models are maintained that include a projection of each issuer’s future financial performance, including prospective debt servicing capabilities, capital structure composition, and the value of the collateral. The analysis incorporates the macroeconomic environment, industry conditions in which the issuer operates, the issuer’s current competitive position, its vulnerability to changes in the competitive and regulatory environment, issuer liquidity, issuer commitment to bondholders, issuer creditworthiness, and asset protection. Part of the process also includes running downside scenarios to evaluate the expected likelihood of default as well as potential losses in the event of default. Based on the analysis performed, the Company did not recognize a credit loss on foreign bonds during the period. The Company has evaluated its investment portfolio and has determined that an allowance for expected credit losses on its investments is not required. The Company recorded the following impairments on its investment portfolio for the quarters and nine months ended September 30, 2023 and 2022 and are related to securities in an unrealized loss position where the Company had an intent to sell the securities:

(1) In response to a rising interest rate environment, the Company took action early in April 2022 to shorten the duration of its fixed maturities portfolio. In connection with these actions, the Company identified fixed maturities securities with a weighted average life of five years or greater as having an intent to sell resulting in other-than-temporary impairment losses. The majority of which were sold in the 2nd quarter of 2022. Most of the proceeds from the sale of these securities were reinvested into fixed income investments with maturities of two years. As a result of these actions, the Company's book yield rose over time. Book yield was approximately 2.2% at December 31, 2021 and 4.0% at September 30, 2023. Accumulated Other Comprehensive Income (Loss), Net of Tax Accumulated other comprehensive income (loss), net of tax, as of September 30, 2023 and December 31, 2022 was as follows:
