“Other” medical claims and benefits payable include amounts payable to certain providers for which we act as an intermediary on behalf of various government agencies without assuming financial risk. Such receipts and payments do not impact our consolidated statements of income. Non-risk provider payables amounted to $225 million, $167 million and $119 million, as of December 31, 2016, 2015 and 2014, respectively. The following table presents the components of the change in our medical claims and benefits payable for the periods indicated. The amounts presented for “Components of medical care costs related to: Prior periods” represent the amount 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.

That portion of our total medical claims and benefits payable liability that is most subject to variability in the estimate is IBNP. Our IBNP, as included in medical claims and benefits payable, represents our best estimate of the total amount of claims we will ultimately pay with respect to claims that we have incurred as of the balance sheet date. We estimate our IBNP monthly using actuarial methods based on a number of factors. Assuming that our initial estimate of IBNP is accurate, we believe that amounts ultimately paid would generally be between 8% and 10% less than the IBNP liability recorded at the end of the period as a result of the inclusion in that liability of the provision for adverse claims deviation and the accrued cost of settling those claims. Because the amount of our initial liability is merely an estimate (and therefore not perfectly accurate), we will always experience variability in that estimate as new information becomes available with the passage of time. Therefore, there can be no assurance that amounts ultimately paid out will fall within the range of 8% to 10% lower than the liability that was initially recorded. Furthermore, because our initial estimate of IBNP is derived from many factors, some of which are qualitative in nature rather than quantitative, we are seldom able to assign specific values to the reasons for a change in estimate—we only know when the circumstances for any one or more factors are out of the ordinary. The use of a consistent methodology in estimating our liability for medical claims and benefits payable minimizes the degree to which the under– or overestimation of that liability at the close of one period may affect consolidated results of operations in subsequent periods. In particular, the use of a consistent methodology should result in the replenishment of reserves during any given period in a manner that generally offsets the benefit of favorable prior period development in that period. Facts and circumstances unique to the estimation process at any single date, however, may still lead to a material impact on consolidated results of operations in subsequent periods. Any absence of adverse claims development (as well as the expensing through general and administrative expense of the costs to settle claims held at the start of the period) will lead to the recognition of a benefit from prior period claims development in the period subsequent to the date of the original estimate. As indicated above, the amounts ultimately paid out on our medical claims and benefits payable liabilities in 2016, 2015, and 2014 were less than what we had expected when we had established those liabilities. The differences between our original estimates and the amounts ultimately paid out (or now expected to be ultimately paid out) for the most part related to IBNP. While many related factors working in conjunction with one another serve to determine the accuracy of our estimates, we are seldom able to quantify the impact that any single factor has on a change in estimate. In addition, given the variability inherent in the reserving process, we will only be able to identify specific factors if they represent a significant departure from expectations. As a result, we do not expect to be able to fully quantify the impact of individual factors on changes in estimates. 2016 We believe that the most significant uncertainties relating to our IBNP estimates at December 31, 2016 are as follows:
• | Our New York health plan acquisition closed on August 1, 2016, which added approximately 35,000 new members. Because these members are new to Molina and we have little insight into their claims history, our estimates of the liability we have incurred for services provided to these members are subject to more than the usual amount of uncertainty.
• | At our Florida, New Mexico, Puerto Rico, Utah and Washington health plans, we overpaid certain inpatient and outpatient facility claims. We adjusted our claims payment history to reflect the claims payment pattern that would have occurred without these overpayments. For this reason, our liability estimates for these health plans are subject to more than the usual amount of uncertainty.
• | Fluctuations in the volume of claims received in a paper format (rather than an electronic format) during the third quarter of 2016 have created more than the usual amount of uncertainty regarding our estimate of the liability for our California health plan.
• | At our Illinois health plan, certain claims with dates of service in 2014 and 2015 were paid in December 2016. Because of these claims with unusually old dates of service, our liability estimate for the Illinois health plan is subject to more than the usual amount of uncertainty.
We recognized favorable prior period claims development in the amount of $192 million for the year ended December 31, 2016. This amount represents our estimate, as of December 31, 2016, of the extent to which our initial estimate of medical claims and benefits payable at December 31, 2015 was more than the amount that will ultimately be paid out in satisfaction of that liability. We believe the overestimation was due primarily to the following factors:
• | A new version of diagnostic codes was required for all claims with dates of service on October 1, 2015, and later. As a result, payment was delayed or denied for a significant number of claims due to provider submission of claims with diagnostic codes that were no longer valid. Once providers were able to submit claims with the correct diagnostic codes, our actual costs were ultimately less than expected.
• | At our New Mexico health plan, we overestimated the impact of several pending high-dollar claims, and our actual costs were ultimately less than expected.
• | At our Washington health plan, we overpaid certain outpatient facility claims in 2015 when the state converted to a new payment methodology. We did not include an estimate in our December 31, 2015 reserves for this potential recovery.
• | At our California health plan, we enrolled approximately 55,000 new Medicaid Expansion members in 2015. For these new members, our actual costs were ultimately less than expected.
2015 We recognized favorable prior period claims development in the amount of $141 million for the year ended December 31, 2015. This amount represented our estimate as of December 31, 2015, of the extent to which our initial estimate of medical claims and benefits payable at December 31, 2014 was more than the amount that was ultimately paid out in satisfaction of that liability. We believe the overestimation was due primarily to the following factors:
• | At our Ohio and California health plans, approximately 61,000 and 100,000 members, respectively, were enrolled in the new Medicaid expansion program during 2014. Also in Ohio, approximately 17,000 members were enrolled in the new MMP program in 2014. Because we lacked sufficient historical claims data, we initially estimated the reserves for these new members based upon a number of factors that included pricing assumptions provided by the state; our expectations regarding pent up demand; our beliefs about the speed at which new members would utilize health care services; and other factors. Our actual costs were ultimately less than expected.
• | At our New Mexico health plan, the state implemented a retroactive increase to the provider fee schedules in mid-2014. As a result, many claims that were previously settled were reopened, and subject to, additional payment. Because our reserving methodology is most accurate when claims payment patterns are consistent and predictable, the payment of additional amounts on claims that in some cases had been settled more than six months before added a substantial degree of complexity to our liability estimation process. Due to the difficulties in addressing that added complexity, liabilities recorded as of December 31, 2014 were in excess of amounts ultimately paid.
• | At our Washington health plan, we collected amounts in 2015 related to certain claims paid in 2013. Such collections were not anticipated in our reserves as of December 31, 2014.
2014 We recognized favorable prior period claims development in the amount of $46 million for the year ended December 31, 2014. This amount represented our estimate as of December 31, 2014, of the extent to which our initial estimate of medical claims and benefits payable at December 31, 2013 was more than the amount that was ultimately paid out in satisfaction of that liability. We believe the overestimation was due primarily to the following factors:
• | At our Ohio health plan, we entered new regions in the state, and a new product, ABD Kids, in July 2013. Because we lacked sufficient historical claims data, we initially estimated the reserves for these new members based upon a number of factors that included pricing assumptions provided by the state; our beliefs about the speed at which new members would utilize health care services; and other factors. Our actual costs were ultimately less than expected.
• | At our Michigan health plan, we overestimated the impact of certain unpaid potentially high-dollar claims. In addition, we overestimated the impact of the flu season on the outpatient claims for November and December 2013, which caused an overestimation in our outpatient reserve liability as of December 31, 2013.
