⁽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 decreased by $1.4 billion for the nine months ended September 30, 2023. Other than with respect to those certain fixed maturity AFS securities intended to be sold as part of the previously announced Fortitude Reinsurance Company Ltd. (“Fortitude Re”) reinsurance transaction (as discussed further below), we do not believe the unrealized loss position as of September 30, 2023, required 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 September 30, 2023, 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. For additional information related to the intent to sell impairments, see “Impairments on Fixed Maturity AFS Securities” below.

As of September 30, 2023, 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 rising interest rates and widening credit spreads 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 September 30, 2023, and December 31, 2022, 96% of the fair value of our corporate bond portfolio was rated investment grade. As of September 30, 2023, and December 31, 2022, the portion of our corporate bond portfolio rated below investment grade had an amortized cost of $3.2 billion and $3.5 billion, respectively, and a fair value of $3.0 billion and $3.3 billion, respectively. Based upon the analysis discussed above, we believe that as of September 30, 2023, and December 31, 2022, we would have recovered the amortized cost of each corporate bond.

As of September 30, 2023, the unrealized losses associated with our MBS and ABS were attributable primarily to rising interest rates and widening credit spreads 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 September 30, 2023, 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

⁽¹⁾Represents impairment of certain fixed maturity AFS securities in an unrealized loss position, resulting from the Company’s intent to sell these securities as part of the previously announced Fortitude Re reinsurance transaction. Within the investment portfolio anticipated to be sold in the transaction, there are additional fixed maturity AFS securities in an unrealized gain position of approximately $212 million pre-tax as of September 30, 2023. Pursuant to the applicable accounting guidance, the Company impaired the securities in a loss position down to fair market value upon entry into the agreement in the second quarter and recognized additional impairment on certain of these securities during the third quarter due to higher interest rates. The Company will recognize a gain for any securities in an unrealized gain position at the time when the transaction closes. See Note 8 for additional information.

The carrying value of the payables for collateral on investments included on the Consolidated Balance Sheets and the fair value of the related investments or collateral (in millions) consisted of the following:



	As of September 30, 2023				As of December 31, 2022
	Carrying		Fair		Carrying		Fair
	Value		Value		Value		Value
Collateral payable for derivative investments ⁽¹⁾	$	4,522	$	4,522	$	3,210	$	3,210

Total payables for collateral on investments	$	7,732	$	8,662	$	6,638	$	7,422

⁽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 6 for additional information.

⁽²⁾Our pledged securities under securities lending agreements are included in fixed maturity AFS securities on the 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 FHLB of Indianapolis (“FHLBI”) are included in fixed maturity AFS securities and mortgage loans on real estate on the 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 September 30, 2023, and December 31, 2022, we were not participating in any open repurchase agreements.

We have elected not to offset our securities lending transactions in the consolidated financial statements. The remaining contractual maturities of securities lending transactions accounted for as secured borrowings (in millions) were as follows:

We accept collateral in the form of securities in connection with repurchase agreements. In instances where we are permitted to sell or re-pledge the securities received, we report the fair value of the collateral received and a related obligation to return the collateral in the consolidated financial statements. In addition, we receive securities in connection with securities borrowing agreements that we are permitted to sell or re-pledge. As of September 30, 2023, the fair value of this collateral received that we are permitted to sell or re-pledge was $25 million, and we had not re-pledged any of this collateral to cover our collateral requirements.

We also accept collateral from derivative counterparties in the form of securities that we are permitted to sell or re-pledge. As of September 30, 2023, the fair value of this collateral received that we are permitted to sell or re-pledge was $1.0 billion, and we had re-pledged $335 million of this collateral to cover our collateral requirements.

We have also pledged fixed maturity AFS securities to derivative counterparties with a fair value of $87 million as of September 30, 2023.

As of September 30, 2023, our investment commitments were $2.3 billion, which included $1.8 billion of LPs, $257 million of mortgage loans on real estate and $217 million of private placement securities.
