Jackson Financial JXN Effect of changes in equity markets

At each reporting date, the Company regularly evaluates the inputs and assumptions to be used to measure the fair value of the MRB assets and MRB liabilities. In prior periods, the non-performance risk adjustment was determined based on credit spreads indicated by a blend of yields on similarly rated peer debt and yields on Company debt. As of June 30, 2023, non-performance risk is incorporated into the calculation through the adjustment of the risk-free rate curve based only on credit spreads for debt and debt-like instruments issued by the Company or its insurance operating subsidiaries, adjusted, as necessary, to reflect the financial strength ratings of the issuing insurance subsidiaries. The change was made as a result of management’s determination that the reliability of credit spreads on debt and debt-like instruments issued by the Company as a measure of company-specific credit risk has increased due to sustained levels of market trading volume of these instruments. For the three months ended June 30, 2023, this change in estimate resulted in other comprehensive income of $692 million and is reflected as a component of the change in non-performance risk on market risk benefits in Condensed Consolidated Statements of Comprehensive Income (Loss).
