Quarterly Financial Information Disclosure [Abstract]

Schedule of Quarterly Financial Information

The following table presents selected unaudited consolidated financial data for each of the eight quarters in the two-year period ended December 31, 2015. The selected quarterly financial data should be read in conjunction with the Company's consolidated financial statements and the related notes and "Item 7: Management's Discussion and Analysis of Financial Condition and Results of Operations." This information has been derived from the Company's unaudited consolidated financial statements that, in management's opinion, reflect all recurring adjustments necessary to fairly state this information when read in conjunction with the Company's consolidated financial statements and the related notes appearing in the section entitled "Consolidated Financial Statements," Net income (loss) per share-basic and diluted, for the four quarters of each fiscal year may not sum to the total for the fiscal year because of the different number of shares outstanding during each period. The results of operations for any quarter are not necessarily indicative of the results to be expected for any future period.
