Reclassifications	Reclassifications In connection with the Company's adoption of ASU 2016-18, “Statement of Cash Flows-Restricted Cash,” the Company reclassified certain 2018 amounts in the condensed consolidated statements of cash flows to include restricted cash when reconciling the beginning-of-period and end-of-period cash amounts shown on the statement of cash flows to conform to the current period presentation. To comply with the Commission’s final rule on Disclosure Simplification, the Company’s presentation of the prior period’s condensed consolidated statement of stockholders’ equity has been reclassed to conform to the current period format.
