(11) | Redeemable Convertible Preferred Stock
On April 13, 2012, the Company signed a securities purchase agreement (the “Securities Purchase Agreement”) with a private investor for the sale (the “Preferred Stock Financing”) of 1,000,000 shares of the Company’s Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”) at $5.00 per share and 325,000 warrants to purchase shares of the Company’s common stock expiring in May 2020. The Series A Convertible Preferred Stock shares are initially convertible into 1,000,000 shares of the Company’s common stock at a conversion price of $5.00 per share. The warrants were issued in two tranches with 125,000 of such warrants at an initial exercise price of $6.00 per share and 200,000 of such warrants at an initial exercise price of $7.00 per share. On May 2, 2012, the Company completed the issuance of the Series A Convertible Preferred Stock and warrants. On April 30, 2012, the Company filed an Articles of Amendment to its Articles of Incorporation designating 1,000,000 shares of the Company’s authorized preferred stock as Series A Convertible Preferred Stock. The Company also entered into a Registration Rights Agreement and Investor Rights Agreement with the private investor. The Series A Convertible Preferred Stock ranks senior to all other equity instruments of the Company, including the Company’s common stock. The Series A Convertible Preferred Stock accrues cumulative dividends at a rate of 6% per annum, whether or not dividends have been declared by the Board of Directors and whether or not there are profits, surplus or other funds available for the payment of such dividends. The Company may pay such dividends in shares of the Company’s common stock based on the then current market price of the common stock. Prior to the repricing agreement discussed below, at any time following a material default by the Company, as defined in the Securities Purchase Agreement, or April 30, 2017, the holders of a majority of the outstanding shares of the Series A Convertible Preferred Stock may require the Company to redeem the Series A Convertible Preferred Stock at a redemption price equal to the lessor of (i) the liquidation preference per share (initially $5.00 per share, subject to adjustments for certain future equity transactions defined in the Securities Purchase Agreement) and (ii) the fair market value of the Series A Convertible Preferred Stock per share, as determined in good faith by the Company’s Board of Directors. As of December 31, 2017 and 2016, the redemption price per share was $5.00 in both years. The redemption price, plus any accrued and unpaid dividends, shall be payable in 36 equal monthly installments plus interest at an annual rate of 6%. The preferred stock and warrants were issued for a total of $5.0 million. This amount was allocated to the preferred stock and warrants based on their relative fair values. The fair value of the warrants was calculated using the Black Scholes-Merton pricing model using the following weighted average assumptions, at the grant date:
Number of warrants |  | 325,000 |
Exercise price | $ | 6.62 |
Expected volatility of underlying stock |  | 74 | %
Risk-free interest rate |  | 1.62 | %
Dividend yield |  | 0 | %
Expected life of warrants |  | 8 years |
Weighted-average fair value of warrants | $ | 3.11 |
Expiration date |  | May 2, 2020 |
Based on these calculations and the actual consideration, the warrants were valued at $840,000 and the Series A Convertible Preferred Stock was valued at $4,160,000. The initial values allocated to the warrants were recognized as a discount on the Series A Convertible Preferred Stock, with a corresponding charge to additional paid-in capital. The discount related to the warrants is accreted to retained earnings through the scheduled redemption date of the mandatorily redeemable Series A Convertible Preferred Stock. Discount accretion for the years ended December 31, 2017 and 2016 totaled $0.06 million and $0.05 million, respectively. At December 31, 2017 and December 31, 2016, the company had accrued but unpaid dividends totaling $0.08 million and $0.23, respectively, which is included in the accounts payable and other accrued expenses in the consolidated balance sheets. In connection with the issuance of the Company’s senior secured Term Note, described in Note 8, the Company has agreed with the Purchaser of the Term Note and the holder of the Preferred Stock (the “Holder”) not to declare, authorize or pay any cash dividends on the Preferred Stock until the earlier of (i) March 22, 2018, or (ii) the date the obligations under the Note Purchase Agreement have been paid in full (the “Standstill Period”), without the prior written consent of the Purchaser. Following the expiration of the Standstill Period, for so long as the obligations under the Note Purchase Agreement remain outstanding, the Company may, at its sole discretion, declare, authorize or pay dividends in cash on the Preferred Stock so long as no event of default exists under the Term Note or would result therefrom. The Holder also agreed that it shall not exercise its rights to require the Company to redeem any of the Preferred Stock during the Standstill Period. Following the expiration of the Standstill Period, so long as the obligations under the Note Purchase Agreement remain outstanding, the Holder may compel the Company to redeem shares of Preferred Stock provided no event of default exists under the Term Note or would result from such redemption. In consideration for the Holder’s consent to the foregoing restrictions on the payment of cash dividends on or redemption of the Preferred Stock, the Company entered into a repricing agreement with the Holder (the “Repricing Agreement”) on August 1, 2017. Pursuant to the repricing agreement, each share of Series A Preferred Stock will be initially convertible, at the option of the holder, into one (1) share of common stock at a conversion price of $2.26 per share of common stock, so that the Series A Preferred Stock sold to the Holder are currently convertible into an aggregate of 2,212,389 shares of common stock as of December 31, 2017. In addition, Pursuant to the Repricing Agreement, the Series A Warrants sold to the Holder is exercisable for 125,000 shares of common stock at an initial exercise price of $2.72 per share and the Series B Warrants sold to the Holder is exercisable for 200,000 shares of common stock at an initial exercise price of $3.17 per share. In order to comply with the rules of the NASDAQ Stock Market, the Repricing Agreement prohibits the issuance of more than 19.99% of our common stock or voting power outstanding to the Holder as of the date of the Repricing Agreement without stockholder approval. The Company has agreed to seek the approval of its stockholders as soon as practicable. In the event that stockholder approval is received and the Holder were to convert all of its Series A Preferred Stock into common stock and exercised all of its Common Stock Purchase Warrants for cash, the Holder would be issued more than 19.99% of our common stock and voting power as of the date of the Repricing Agreement. This agreement was approved by a committee of the Board of Directors comprised solely of independent directors.
