Redeemable Preferred Stock [Text Block]	1 0 . Redeemable Preferred Stock At December 31, 2014, the Company had 60,600 shares of redeemable preferred stock outstanding. The shares of redeemable preferred stock were initially recorded at fair value and thereafter increased by accrued paid-in-kind dividends. The Company classified the shares of redeemable preferred within temporary equity on its consolidated balance sheet at December 31, 2014, due to its liquidation rights. The redeemable preferred stock was redeemable in cash upon a deemed liquation event (i.e., the sale of 50% or more of the outstanding shares of voting capital stock) that is not solely within the control of the Company. On March 25, 2015, the Company further amended its articles of incorporation with the consent of more than 80% of the holders of the preferred stock and a majority of the holders of the common stock to restrict the definition of a Liquidation Event to the liquidation, dissolution or winding up of the Company and to eliminate from that definition a change of control or a public offering of the Company. All or part of the preferred stock may be redeemed after one year from the date of issuance, at the option of the Company, by a cash payment of the original purchase price plus any accumulated and as yet unpaid preferred dividends and paid-in-kind dividends. On the effective date of the modification, the Company reclassified the carrying amount of its redeemable preferred stock from temporary equity to permanent equity as the redemption of the redeemable preferred stock was within the Company’s control. Pursuant to agreements effective on or before July 1, 2015, the holders of preferred stock agreed to allow the Company to repurchase their outstanding preferred shares at the original purchase price (i.e. $100 per share) plus all accrued and unpaid preferred dividends. In addition, the holders of 29,550 shares (or 49%) of preferred stock agreed to use such cash received from the Company’s repurchase of their preferred stock to purchase shares of common stock at the same per share price as the common stock offered in the Company’s IPO. The closing of these transactions were conditioned on the completion of the Company’s IPO. Following the closing of the Company’s IPO on August 18, 2015, the Company paid $6.3 million to holders of shares of preferred stock to repurchase such shares and for the payment of accrued dividends. Additionally, the Company issued 294,450 shares of common stock to former holders of the preferred stock for proceeds of $3.1 million. There are no shares of preferred stock outstanding after the closing of the IPO.
