(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. 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, 2016 and 2015, 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, 2016 and 2015 totaled $0.05 million in both years.

At December 31, 2016 and December 31, 2015, the company had accrued but unpaid dividends totaling $0.23 million, in both years, which is included in the accounts payable and other accrued expenses in the consolidated balance sheets.
