| Market Risk Benefits |
MRBs are defined as contracts or contract features that both provide protection to the contract holder from other-than-nominal capital market risk and expose Corebridge to other-than nominal capital market risk. The MRB represents an amount that a policyholder receives in addition to the account balance upon the occurrence of a specific event or circumstance, such as death, annuitization, or periodic withdrawal that involves protection from other-than-nominal capital market risk. Certain contract features, such as GMWBs, GMDBs and guaranteed minimum income benefits (“GMIBs”) commonly found in variable, fixed index and fixed annuities, are MRBs. MRBs are assessed at contract inception using a non-option method involving attributed fees that results in an initial fair value of zero or an option method that results in a fair value greater than zero. MRBs are recorded at fair value, and Corebridge applies a non-option attributed fee valuation method for variable annuity products, and an option-based valuation method (host offset) for both fixed index and fixed products. Changes in the fair value of Market Risk Benefits, net represents changes in the fair value of market risk benefit liabilities and assets (with the exception of our own credit risk changes), and includes attributed rider fees and benefits, net of changes in the fair value of derivative instruments and fixed maturity securities that are used to economically hedge market risk from the variable annuity GMWB riders. The following table presents the balances of and changes in MRBs: | | | | | | | | | | | | | | | | | | | | | | Three Months Ended March 31, 2024 | | Individual

* Certain contracts contain both guaranteed GMDB and GMWB features and are modeled together for the purposes of calculating the MRB. The following is a reconciliation of MRBs by amounts in an asset position and in a liability position to the MRBs amount in the Condensed Consolidated Balance Sheets: | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | March 31, 2024 | | March 31, 2023 | | (in millions) | | Asset* | | Liability* | | Net | | Asset* | | Liability* | | Net | | Individual Retirement | | $ | 968 | | | $ | 4,714 | | | $ | 3,746 | | | $ | 685 | | | $ | 4,680 | | | $ | 3,995 | | | Group Retirement | | 204 | | | 453 | | | 249 | | | 145 | | | 464 | | | 319 | | | Total | | $ | 1,172 | | | $ | 5,167 | | | $ | 3,995 | | | $ | 830 | | | $ | 5,144 | | | $ | 4,314 | |
* Cash flows and attributed fees for MRBs are determined on a policy level basis and are reported based on their asset or liability position at the balance sheet date. For additional information related to fair value measurements of MRBs, see Note 5.
