(Favorable) Unfavorable Developments By Changes In Key Assumptions

The following table provides a summary of the two key assumptions having the most significant impact on our incurred but not paid liability estimates for the years ended December 31, 2022, 2021 and 2020, which are the completion and trend factors. These two key assumptions can be influenced by utilization levels, unit costs, mix of business, benefit plan designs, provider reimbursement levels, processing system conversions and changes, claim inventory levels, claim processing patterns, claim submission patterns and operational changes resulting from business combinations. We had increased estimation uncertainty on our incurred but not reported liability at December 31, 2022 and December 31, 2021. Slowdowns in claims submission patterns and increases in utilization levels for COVID-19 testing and treatment are the primary factors that lead to the increased estimation uncertainty.
