(1)As of March 31, 2022, and December 31, 2021, we recognized $8 million of gross unrealized losses in other comprehensive income (loss) (“OCI”) for fixed maturity AFS securities for which an allowance for credit losses has been recorded. The fair value, gross unrealized losses (in millions) and number of fixed maturity AFS securities where the fair value had declined and remained below amortized cost by greater than 20% were as follows:
| As of March 31, 2022 |
|  |  |  | Gross |  |  | Number |

Total | $ | 70 |  | $ | 11 |  |  |  | 30 |
(1)We may reflect a security in more than one aging category based on various purchase dates. Our gross unrealized losses on fixed maturity AFS securities increased by $2.5 billion for the three months ended March 31, 2022. As discussed further below, we believe the unrealized loss position as of March 31, 2022, did not require an impairment recognized in earnings as (i) we did not intend to sell these fixed maturity AFS securities; (ii) it is not more likely than not that we will be required to sell the fixed maturity AFS securities before recovery of their amortized cost basis; and (iii) the difference in the fair value compared to the amortized cost was due to factors other than credit loss. Based upon this evaluation as of March 31, 2022, management believes we have the ability to generate adequate amounts of cash from our normal operations (e.g., insurance premiums, fee income and investment income) to meet cash requirements with a prudent margin of safety without requiring the sale of our impaired securities. As of March 31, 2022, the unrealized losses associated with our corporate bond, U.S. government bond, state and municipal bond and foreign government bond securities were attributable primarily to widening credit spreads and rising interest rates since purchase. We performed a detailed analysis of the financial performance of the underlying issuers and determined that we expected to recover the entire amortized cost of each impaired security. Credit ratings express opinions about the credit quality of a security. Securities rated investment grade (those rated BBB- or higher by S&P Global Ratings (“S&P”) or Baa3 or higher by Moody’s Investors Service (“Moody’s”)) are generally considered by the rating agencies and market participants to be low credit risk. As of March 31, 2022, and December 31, 2021, 96% of the fair value of our corporate bond portfolio was rated investment grade. As of March 31, 2022, and December 31, 2021, the portion of our corporate bond portfolio rated below investment grade had an amortized cost of $3.7 billion and a fair value of $3.6 billion and $3.8 billion, respectively. Based upon the analysis discussed above, we believe that as of March 31, 2022, and December 31, 2021, we would have recovered the amortized cost of each corporate bond. As of March 31, 2022, the unrealized losses associated with our mortgage-backed securities and ABS were attributable primarily to widening credit spreads and rising interest rates since purchase. We assessed for credit impairment using a cash flow model that incorporates key assumptions including default rates, severities and prepayment rates. We estimated losses for a security by forecasting the underlying loans in each transaction. The forecasted loan performance was used to project cash flows to the various tranches in the structure, as applicable. Our forecasted cash flows also considered, as applicable, independent industry analyst reports and forecasts and other independent market data. Based upon our assessment of the expected credit losses of the security given the performance of the underlying collateral compared to our subordination or other credit enhancement, we expected to recover the entire amortized cost of each impaired security. As of March 31, 2022, the unrealized losses associated with our hybrid and redeemable preferred securities were attributable primarily to wider credit spreads caused by illiquidity in the market and subordination within the capital structure, as well as credit risk of underlying issuers. For our hybrid and redeemable preferred securities, we evaluated the financial performance of the underlying issuers based upon credit performance and investment ratings and determined that we expected to recover the entire amortized cost of each impaired security. Credit Loss Impairment on Fixed Maturity AFS Securities We regularly review our fixed maturity AFS securities for declines in fair value that we determine to be impairment-related, including those attributable to credit risk factors that may require an allowance for credit losses. Changes in the allowance for credit losses on fixed maturity AFS securities (in millions), aggregated by investment category, were as follows:

Credit Losses on Mortgage Loans on Real Estate In connection with our recognition of an allowance for credit losses for mortgage loans on real estate, we perform a quantitative analysis using a probability of default/loss given default/exposure at default approach to estimate expected credit losses in our mortgage loan portfolio as well as unfunded commitments related to commercial mortgage loans, exclusive of certain mortgage loans held at fair value. Changes in the allowance for credit losses on mortgage loans on real estate (in millions) were as follows:

(1)Due to improving economic projections, the provision for credit loss expense decreased by $19 million and $20 million for the three months ended March 31, 2022 and 2021, respectively. We recognized $(1) million and $4 million of credit loss benefit (expense) related to unfunded commitments for mortgage loans on real estate for the three months ended March 31, 2022 and 2021, respectively. (2)Accrued investment income on mortgage loans on real estate totaled $49 million and $51 million as of March 31, 2022 and 2021, respectively, and was excluded from the estimate of credit losses. Alternative Investments As of March 31, 2022, and December 31, 2021, alternative investments included investments in 318 and 311 different partnerships, respectively, and represented approximately 2% of total investments. Impairments on Fixed Maturity AFS Securities Details underlying credit loss benefit (expense) incurred as a result of impairments that were recognized in net income (loss) and included in realized gain (loss) on fixed maturity AFS securities (in millions) were as follows:

(1)We obtain collateral based upon contractual provisions with our counterparties. These agreements take into consideration the counterparties’ credit rating as compared to ours, the fair value of the derivative investments and specified thresholds that if exceeded result in the receipt of cash that is typically invested in cash and invested cash. This also includes interest payable on collateral. See Note 4 for additional information. (2)Our pledged securities under securities lending agreements are included in fixed maturity AFS securities on our Consolidated Balance Sheets. We generally obtain collateral in an amount equal to 102% and 105% of the fair value of the domestic and foreign securities, respectively. We value collateral daily and obtain additional collateral when deemed appropriate. The cash received in our securities lending program is typically invested in cash and invested cash or fixed maturity AFS securities. (3)Our pledged investments for Federal Home Loan Bank (“FHLB”) of Indianapolis (“FHLBI”) are included in fixed maturity AFS securities and mortgage loans on real estate on our Consolidated Balance Sheets. The collateral requirements are generally 105% to 115% of the fair value for fixed maturity AFS securities and 155% to 175% of the fair value for mortgage loans on real estate. The cash received in these transactions is primarily invested in cash and invested cash or fixed maturity AFS securities. We have repurchase agreements through which we can obtain liquidity by pledging securities. The collateral requirements are generally 80% to 95% of the fair value of the securities, and our agreements with third parties contain contractual provisions to allow for additional collateral to be obtained when necessary. The cash received in our repurchase program is typically invested in fixed maturity AFS securities. As of March 31, 2022, and December 31, 2021, we were not participating in any open repurchase agreements.

As of March 31, 2022, the fair value of all collateral received that we are permitted to sell or re-pledge was $22 million, and we had re-pledged all of this collateral to cover initial margin and over-the-counter collateral requirements on certain derivative investments.
