(a)

The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation. The Company follows a standard process, which considers historical denial and collection experience and other factors, to estimate contractual allowances and implicit price concessions, recording adjustments in the current period as changes in estimates. Based on this process, during the fourth quarter of 2018, the Company increased its reserves for revenues and accounts receivable by approximately $35 million (see Note 3 to the consolidated financial statements). Net revenues for 2017 have been restated to reflect the impact of new revenue recognition rules that became effective January 1, 2018 and were adopted on a retrospective basis (see Note 2 to the consolidated financial statements).
