9.	Preferred Stock

On June 30, 2017, we modified our existing credit facility with WAVI Holding AG, ("WAVI"), a principal stockholder of the Company. Pursuant to the modification, WAVI agreed to exchange its existing credit facility, including $4.25 million of principal and accrued interest outstanding as of June 1, 2017, for 4,250 shares of the Company's Series A Preferred Stock, which has a fixed, aggregate stated value of $4.25 million. The preferred shares being issued to WAVI are not convertible into any other form of equity and can only be redeemed at the stated value of $4.25 million at times and in amounts solely determined by the Company. The preferred shares also carry an annual cash dividend of 10% of the outstanding stated value, calculated and payable in arrears on a quarterly basis. The preferred shares have a liquidation preference over the common shareholders. No additional consideration was provided to WAVI for entering into this agreement. The exchange resulted in no gain or loss on the transaction. In both the three and six months ended June 30, 2017 we did not pay or accrue any dividends on the preferred stock.
