The total estimate of benefits payable for claims incurred but not reported, or IBNR, is included within the net incurred claims amounts. At September 30, 2023, benefits payable included IBNR of approximately $6.4 billion, primarily associated with claims incurred in 2023. Amounts incurred related to prior periods vary from previously estimated liabilities as the claims ultimately are settled. Negative amounts reported for incurred related to prior years result from claims being ultimately settled for amounts less than originally estimated (favorable development). Our reserving practice is to consistently recognize the actuarial best estimate of our ultimate liability for claims. Actuarial standards require the use of assumptions based on moderately adverse experience, which generally results in favorable reserve development, or reserves that are considered redundant. For additional information regarding our benefits payable and benefits expense recognition, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" in our 2022 Form 10-K.
