Accordingly, we reclassified $28,501 of restricted cash into cash, cash equivalents, and restricted cash as of March 31, 2017 for a total balance of $150,914, which resulted in an $11 increase in net cash provided by operating activities in the condensed consolidated statement of cash flows for the three months ended March 31, 2017. The adoption of the guidance also requires us to reconcile our cash balance on the condensed consolidated statement of cash flows to the cash balance presented on the condensed consolidated balance sheet, as well as make disclosures about the nature of restricted cash balances. See Note 3. “Restricted Cash” for these disclosures.
