The Company recorded $50,000 as research and development expense for the fourth quarter of 2016 to reflect the fair market value of the common stock issued.

Preferred Stock

The Company has authorized 20,000,000 shares of preferred stock with a par value of $0.001 per share.

Redeemable Convertible Series B Preferred Stock: In August 2015, the Company sold 5,000 shares of Series B Convertible Preferred Stock and warrants to purchase 6,250,000 shares of the Company's common stock for an aggregate purchase price of $1,000 per share resulting in gross proceeds of $5.0 million. Each share of preferred stock is convertible into 1,250 shares of common stock which results in an effective conversion price of $0.80 per common share and can be converted by the holder at any time. The Series B Preferred Stock also has a "down-round" protection feature provided to the investors if the Company subsequently issues or sell any shares of common stock, stock options, or convertible securities at a price less than the conversion price of $0.80 per common share. The conversion price is automatically adjusted down to the price of the instrument being issued. In October 2016, as a result of the Series C Preferred Stock Agreement (discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B Preferred Stock was reset to $0.25. The Series B Preferred Stock has liquidation preference over other preferred shares and common stock and have voting rights equal to the number of common shares into which each holder's preferred stock is convertible as of the record date. If dividends are declared on the common stock, the holders of the preferred stock shall be entitled to participate in such dividends on an as-if converted basis. The warrants are exercisable at a price of $1.15 per share, subject to reset, and expire five years from the issuance date.

In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, Series B Preferred stockholders receive an amount per share equal to the conversion price of $0.25, subject to down-round adjustment, multiplied by the as-if converted share amount of 14,501,500 common shares, totaling $3.6 million. If upon the liquidation, the assets are insufficient to permit payments to the Series B holders, all assets legally available will be distributed in a pro rata basis among the Series B holders in proportion to the full amounts they would otherwise be entitled to receive. Any remaining assets are distributed pro rata among the common stockholders.

Subject to certain trigger events occurring, the Series B Preferred stockholders have the right to force the Company to redeem the shares of preferred stock at a price per preferred share equal to the greater of (A) 115% of the conversion amount and (B) the product of (1) the conversion rate in effect at such time and (2) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding such triggering event and ending on the date such holder delivers the notice of redemption. Such triggering events include:

 As certain of these triggering events are considered to be outside the control of the Company, the Series B Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet. As further described in Note 8-Series B Preferred Stock Amendment, we amended the terms of the Series B Preferred Stock to exclude certain financing transactions from triggering the redemption right described above. 

In December 2015, a Series B Preferred stockholder converted 500 shares of its preferred stock to common stock at the conversion rate of 1,250:1 resulting in the issuance of 625,000 shares of common stock. In March 2016, another Series B Preferred stockholder converted 8 shares of its preferred stock to common stock at the same ratio resulting in the issuance of 10,000 shares of common stock. In October 2016, as a result of the Series C Preferred Stock Agreement (discussed below), the conversion price of the Series B Preferred Stock was reset to $0.40. From October 2016 to December 31, 2016, Series B Stockholders converted 461 shares of its preferred stock to common stock, at the conversion rate of 2,500:1 resulting in the issuance of 1,152,500 shares of common stock. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B Preferred Stock was reset to $0.25. For the three months ended March 31, 2017, Series B stockholders converted 405.625 shares at a conversion rate of 4000:1 resulting in the issuance of 1,622,500 shares of common stock. As a result of these conversions, the liquidation preference for the Series B Preferred Stock has been reduced to $3.6 million as of March 31, 2017.

Convertible Series C Preferred Stock: In October 2016, the Company sold 500 shares of Series C convertible preferred stock with a purchase price of $1,000 per share for gross proceeds of $500,000 to a healthcare investment fund under the Series C Preferred Stock Agreement. Each share of Series C Preferred Stock is convertible into 2,500 shares of common stock which results in an effective conversion price of $0.40 per common share. This resulted in the reduction of the conversion price of the Series B Preferred Stock to $0.40 and a reduction in the exercise price of the Series B warrants to $0.40. On December 29, 2016, as a result of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series C Preferred Stock was reset to $0.25. As part of the terms of the Series C Preferred Stock Agreement, the Company entered into a Registration Rights Agreement with the purchaser to file a registration statement to register for resale the shares of common stock underlying the preferred shares within 30 days following the closing of the agreement. Each Preferred Stock is convertible into common stock at any time at the election of the investor. The terms of the Series C Convertible Preferred Stock are as follows:

The Series C Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet because the Most Favored Nation provision is a redemption feature that is outside the control of the Company.

At the date of the financing, because the effective conversion rate of the preferred stock was less than the market value of the Company’s common stock, a beneficial conversion feature of $325,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in October 2016, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

In December 2016, the Series C Preferred stockholder converted 39 shares of its preferred stock to common stock as allowed under the Series C Preferred Stock Agreement, resulting in the issuance of 97,500 shares of common stock at an effective price of $0.40 per share. On December 29, 2016, as a result of the signing of the Series D Preferred Stock Agreement (as discussed below), the conversion price of the Series B and Series C Preferred Stock was reset to $0.25. From the date of this reset to December 31, 2016, a Series C Stockholder converted 75 shares of their preferred stock to common stock, resulting in the issuance of 300,000 shares of common stock. For the three months ended March 31, 2017, the Series C stockholder converted 386 shares at a conversion rate of 4000:1 resulting in the issuance of 1,544,000 shares of common stock. As a result, all Series C Preferred Stock has been converted to common stock and there is no liquidation preference outstanding as of March 31, 2017.

In addition, as a result of the Series D financing and the adjustment in the conversion price, a beneficial conversion feature of $175,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in January 2017, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

Convertible Series D Preferred Stock: In January 2017, the Company sold 1,200 shares of Series D convertible preferred stock with a purchase price of $1,000 per share for gross proceeds of $1,200,000 to a healthcare investment fund and other private investors under the Series D Preferred Stock Agreement. Each share of Series D Preferred Stock is convertible into 4,000 shares of common stock which results in an effective conversion price of $0.25 per common share. This resulted in the reduction of the conversion price of the Series B and Series C Preferred Stock to $0.25 and a reduction in the exercise price of the Series B warrants to $0.25. As part of the terms of the Series D Preferred Stock Agreement, the Company entered into a Registration Rights Agreement with the purchasers to file a registration statement to register for resale the shares of common stock underlying the preferred shares within 30 days following the closing of the agreement. Each Preferred Stock is convertible into common stock at any time at the election of the investor. The terms of the Series D Convertible Preferred Stock are identical to those of the Series C Convertible Preferred Stock agreement discussed above with the exception of the conversion price which is $0.25 per common share.

The Series D stock has liquidation preference over common stock. In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, Series D Preferred stockholders receive an amount per share equal to the conversion price of $0.25, subject to down-round adjustment, multiplied by the as-if converted share amount of 2,824,000 common shares, totaling $0.7 million.

The Company also considered the classification of the Series D Preferred Stock Agreement. , the Series D Preferred Stock is considered to be contingently redeemable convertible and as a result, has been classified as mezzanine equity in the Company's balance sheet because the Most Favored Nation provision is a redemption feature that is outside the control of the Company.

At the date of the financing, because the effective conversion rate of the preferred stock was less than the market value of the Company’s common stock, a beneficial conversion feature of $536,000 has been recorded as a discount to the preferred stock and an increase to additional paid in capital. Because the preferred stock is perpetual, in January 2017, the Company fully amortized the discount related to the beneficial conversion feature on the deemed dividend in the consolidated statement of operations.

For the three months ended March 31, 2017, the Series D stockholders converted 494 shares at a conversion rate of 4000:1 and a conversion price of $0.25 per share resulting in the issuance of 1,976,000 shares of common stock.
