On January 1, 2018, the Company adopted ASC 606, using the modified retrospective transition method applied to all contracts as of January 1, 2018.

The new guidance allows entities to make non-substantive changes to awards without accounting for them as modifications, which results in fewer changes to the terms of an award being accounted for as modifications and reduces diversity in practice when applying modification accounting.

Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016‑18 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted.
