On January 27, 2016, we filed an amendment of our Amended and Restated Certificate of Incorporation, as amended, to effect a 1-for-15 reverse stock split of our common stock (the “Reverse Stock Split”). The Reverse Stock Split became effective in the stock market upon commencement of trading on January 28, 2016. As a result of the Reverse Stock Split, every fifteen shares of our pre-Reverse Stock Split common stock were combined and reclassified into one share of our common stock. No fractional shares were issued in connection with the Reverse Stock Split, and cash paid to stockholders for potential fractional shares was insignificant. The number of shares of common stock subject to outstanding options, restricted stock units, warrants and convertible securities were also reduced by a factor of fifteen as of January 27, 2016. All historical share and per share amounts reflected throughout this report have been adjusted to reflect the Reverse Stock Split. The authorized number of shares and the par value per share of our common stock were not affected by the Reverse Stock Split.
