Selected Quarterly Consolidated Financial Data (Unaudited)

The following tables set forth our unaudited condensed consolidated statements of operations data for the eight quarterly periods ended December 31, 2014. We have prepared this unaudited information on a basis consistent with our audited consolidated financial statements, reflecting all normal recurring adjustments that we consider necessary for a fair presentation of our financial position and operating results for the fiscal quarters presented. Basic and diluted income (loss) per share is computed independently for each of the quarters presented. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted income (loss) per share.

The following tables set forth selected unaudited financial data for each quarter for the last two fiscal years (in thousands, except for per share amounts):
