Series A-2 Preferred Stock Each share of Series A-2 Preferred Stock has a stated value of $7,500 per share (the “A-2 Stated Value”), a liquidation preference equal to the A-2 Stated Value, and is convertible at the holder’s election into common stock at a conversion price per share of $21.60 as of June 30, 2019.

As of June 30, 2019, the Company has recorded $90,000 in accrued dividends in “Accrued expenses and other liabilities” on the accompanying Condensed Consolidated Balance Sheet related to the remaining Series A-2 Preferred Stock outstanding. The Company, at its option, may redeem all or a portion of the Series A-2 Preferred Stock in cash at a price per share of $8,250 per share (equal to $7,500 per share multiplied by 110%) plus all accrued and unpaid dividends. Series B Preferred Stock During the six months ended June 30, 2019, 75 shares (constituting all issued and outstanding shares) of Series B Preferred Stock were converted to 26,786 shares of the Company’s common stock at the conversion price of $2.80 per share. As of June 30, 2019, no shares of Series B Preferred Stock remain issued and outstanding. Series C Preferred Stock In January 2018, the Company closed a registered direct offering of 1,750 shares of its Series C Preferred Stock for total gross proceeds to the Company of $1,750,000. The shares of Series C Preferred Stock were sold at a price equal to their stated value of $1,000 per share and are convertible into shares of the Company’s common stock at a conversion price of $3.00 per share. During the six months ended June 30, 2019, 50 shares of Series C Preferred Stock were converted to 16,667 shares of the Company’s common stock. As of June 30, 2019, 475 shares of Series C Preferred Stock remain issued and outstanding, which are convertible to 158,333 shares of the Company’s common stock. Subject to certain exceptions, the Company has agreed to provide the purchasers, during the period that the purchasers continue to hold Series C Preferred Stock, a right of participation for up to 100% of any future offering of its common stock or other securities or equity linked debt obligations until January 2020. In addition, the Company has agreed that it will not enter into certain “fundamental transactions,” including transactions constituting a change of control of the Company, certain reorganization transactions or a sale of all or substantially all of the Company’s assets, except as pursuant to written agreements in form and substance satisfactory to the holders of a majority of the outstanding shares of Series C Preferred Stock including the Lead Investor and on terms with respect to the Series C Preferred Stock as set forth in the Certificate of Designation of Rights, Powers, Preferences, Privileges and Restrictions of the Series C Preferred Stock. In accordance with ASC Topic 815, we evaluated whether our convertible preferred stock contains provisions that protect holders from declines in our stock price or otherwise could result in modification of the exercise price and/or shares to be issued under the respective preferred stock agreements based on a variable that is not an input to the fair value of a “fixed-for-fixed” option and require a derivative liability. The Company determined no derivative liability is required under ASC Topic 815 with respect to our convertible preferred stock. A contingent beneficial conversion amount is required to be calculated and recognized when and if the adjusted $21.60 conversion price of the Series A-2 Preferred Stock is adjusted to reflect a down round stock issuance. In the event there is an adjustment to the conversion price, our earnings per share calculations will be impacted by the resulting deemed dividend.
