QUARTERLY FINANCIAL DATA (unaudited) [Abstract] |
Quarterly Financial Data | The following table sets forth unaudited consolidated statements of operations data for the eight quarters in the period ended December 31, 2018. This information has been derived from Acacia’s unaudited condensed consolidated financial statements that have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the information when read in conjunction with the audited consolidated financial statements and related notes thereto. Acacia’s quarterly results have been, and may in the future be, subject to significant fluctuations. As a result, Acacia believes that results of operations for interim periods should not be relied upon as any indication of the results to be expected in any future periods.
