Our estimates of medical claims and benefits payable recorded at December 31, 2020, and 2019 developed favorably by approximately $216 million and $66 million as of September 30, 2021, and 2020, respectively. The favorable prior period development recognized in the nine months ended September 30, 2021 was primarily due to lower than expected utilization of medical services by our members and improved operating performance. Consequently, the ultimate costs recognized in 2021, as claims payments were processed, were lower than our previous estimates in 2020.
