Stockholders' Equity, Reverse Stock Split   At a special meeting held on February 8, 2016, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to effect a reverse split of the Company’s common stock at a ratio between 1:5 to 1:10 in order to ensure that adequate authorized but unissued shares would be available for anticipated future financings, and to satisfy requirements for the continued listing of the Company’s common stock on the NASDAQ Capital Market. In addition, the proposal approved by the stockholders provided that if the reverse split was effected, the number of shares of common stock that the Company is authorized to issue remained unchanged at 40,000,000. The Company’s stockholders further authorized the board of directors to determine the ratio at which the reverse split would be effected by filing an appropriate amendment to the Company’s certificate of incorporation. The board of directors authorized the ratio of the reverse split on February 24, 2016, and effective at the close of business on March 4, 2016, the Company’s certificate of incorporation was amended to effect a 1-for-10 reverse split of the Company’s common stock (the “2016 Reverse Split”). All share and per share numbers included in these consolidated financial statements give effect to the 2016 Reverse Split.

[1] These warrants have a certain type of cash settlement feature or their exercise price for which the warrant may be exercised are subject to adjustment for “down rounds” and the warrants have been accounted for as derivative instruments as described in Note 3, with the exception of 9,704 warrants issued in August 2014.
[2] Due to the issuance of common stock at $1.50 per share as part of the November 2016 Underwritten Offering, the remaining outstanding warrants issued as part of the February 2013 Public Offering were adjusted to reflect the revised exercise price of $1.50 each.
