Such receipts and payments do not impact our consolidated statements of income. Non-risk provider payables amounted to $112 million and $107 million as of June 30, 2019, and December 31, 2018, respectively.

The amounts presented for “Components of medical care costs related to: Prior periods” represent the amounts by which our original estimate of medical claims and benefits payable at the beginning of the period were more than the actual amount of the liability, based on information (principally the payment of claims) developed since that liability was first reported.

_______________________


(1)	The June 30, 2018, amount includes the 2018 benefit of the 2017 Marketplace CSR reimbursement of $76 million.

Our estimates of medical claims and benefits payable recorded at December 31, 2018, and 2017 developed favorably by approximately $232 million and $298 million as of June 30, 2019, and 2018, respectively.

The favorable prior year development recognized in the six months ended June 30, 2019, was primarily due to lower than expected utilization of medical services by our Medicaid members, and improved operating performance. Consequently, the ultimate costs recognized in 2019, as claims payments were processed, was lower than our original estimates in 2018.
