Significant Accounting Policies [Line Items]

Impact of Adoption

In November 2016, the FASB issued ASU No. 2016-18 (Topic 230), Restricted Cash, Statement of Cash Flows (ASU 2016-18). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash and, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, 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 consolidated statement of cash flows. The Company adopted ASU No. 2016-18 as of January 1, 2019. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amount shown on the consolidated statements of cash flows (in thousands):

	December 31, 2019		December 31, 2018
Cash and cash equivalents	$	57,937	$	71,064
Restricted cash		203		203
Cash, cash equivalents and restricted cash	$	58,140	$	71,267
