3. STOCKHOLDERS’ EQUITY
2016 Reverse Stock Split and Recapitalization
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 and corresponding reduction in authorized shares 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.
October 2015 Registered Direct Offering
On October 1, 2015, the Company completed a registered direct offering of 101,727 shares of our common stock and Series B pre-funded warrants to purchase an aggregate of 48,274 shares of our common stock (the “2015 Pre-Funded Warrants”) at an offering price of $22.00 per share (collectively, the “2015 Registered Offering”).
In a concurrent private placement (the “2015 Private Placement” and, together with the 2015 Registered Offering, the “2015 Offerings”), the Company issued Series A warrants (the “2015 Series A Warrants”) to purchase one share of our common stock for each share of common stock or 2015 Pre-Funded Warrant to purchase one share of common stock purchased in the Registered Offering. The 2015 Series A Warrants cover, in the aggregate, 150,003 shares of common stock and become exercisable on April 1, 2016, at an exercise price of $28.30 per share and expire five years from that date. The Offerings resulted in gross proceeds of $3,300,000 and net proceeds of approximately $2,868,000. A charge of approximately $404,000 was recorded in the year ended December 31, 2015 and represents the amount by which the initial fair value of warrants issued in connection with the 2015 Registered Offering exceeded the net proceeds received from the offering. The net proceeds of the offering were allocated first to the warrants based on their fair value with the residual to common stock. The actual net proceeds were less than the combined fair value of the warrants at the closing date. As a result the company recorded a loss on issuance of derivative warrants of $404,150. Additionally, the placement agent received a warrant to purchase up to 3,750 shares of our common stock at $28.30 per share, the fair value of which was approximately $61,000 at issuance and had no effect on stockholders’ equity.
Under the terms of the 2015 Pre-Funded Warrants, if the Company issues shares of common stock or common stock equivalents at a purchase price (a “Dilutive Price”) less than the then-effective warrant share purchase price for the Pre-Funded Warrants, which is initially $22.00 per share, the number of shares of Common Stock issuable upon the exercise of the 2015 Pre-Funded Warrants will be increased to equal (i) the product of the then-effective warrant share purchase price multiplied by the number of shares of Common Stock for which the 2015 Pre-Funded Warrants may be exercised, divided by (ii) the Dilutive Price. Following any such adjustment, the warrant share purchase price shall be adjusted to equal the Dilutive Price. Similarly, until the Company completes an equity financing with gross proceeds of at least $10.0 million, if the Company issues shares of common stock or common stock equivalents for a purchase price less than the then-effective exercise price for the 2015 Series A Warrants, the exercise price of the 2015 Series A Warrants will be lowered to equal that lower price.
Subsequent to March 31, 2016, the Company and warrant holders amended certain warrant agreements that were issued as part of the 2015 Registered Offering (see Note 10).
In connection with the entry into the purchase agreement, the Company and the purchasers entered into a registration rights agreement, which required the Company to file a registration statement on Form S-3 to provide for the resale of the shares of Common Stock issuable upon the exercise of the 2015 Series A Warrants. The Company will also be required to file one or more registration statements from time to time to register the issuance or resale of any additional shares of Common Stock that may become issuable as a result of the Offerings. The Company will be obligated to use its commercially reasonable efforts to keep any registration statement effective until the earlier of (i) the date on which the shares of Common Stock subject to the registration statement may be sold without registration pursuant to Rule 144 under the Securities Act, or (ii) the date on which all of the shares of Common Stock subject to the registration statement have been sold under the registration statement or pursuant to Rule 144 under the Securities Act or any other rule of similar effect.
Registration Rights
In connection with certain securities purchase agreements the Company is required to keep the related registration statements continuously effective under the Securities Act of 1933, as amended (the “Securities Act”), until the earlier of the date when all the registrable securities covered by the registration statement have been sold or such time as all the registrable securities covered by the registration statement can be sold under Rule 144 without any volume limitations. The Company will be allowed to suspend the use of the registration statement for not more than 30 consecutive days on not more than two occasions in any 12-month period (the “Allowed Delay”). If the Company suspends the use of the registration for longer than the Allowed Delay, it may be required to pay to the purchasers liquidated damages equal to 1.5% per month (pro-rated on a daily basis for any period of less than a full month) of the aggregate purchase price of the units purchased until the use of the registration statement is no longer suspended, not to exceed 5% of the aggregate purchase price. As of March 31, 2016, and through the date of this filing, the Company has not concluded that it is probable that damages will become due; therefore, no accrual for damages has been recorded.
Additionally, in connection with certain registered offerings of common stock and warrants, the Company has entered into certain securities purchase agreements which require the Company to use commercially reasonable efforts to keep the applicable registration statements effective for the issuance of shares of common stock pursuant to the exercise of warrants issued in the offering as long as the warrants remain outstanding.
