Quarterly Financial Information Disclosure [Abstract] |
Selected Quarterly Financial Data (Unaudited) | Selected Quarterly Financial Data (Unaudited) The following table presents selected unaudited financial data for each of the eight quarters in the two-year period ended December 31, 2016. The Company believes this information reflects all recurring adjustments necessary to fairly present this information when read in conjunction with the Company's financial statements and the related notes. Net loss per common 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 (in thousands of dollars, except for share and per share data):
