[1] On June 15, 2015 the Company's Board of Directors approved the conversion of the Company's $2.5 million related party debt to Preferred Stock equity. The Preferred Stock will pay a 6.00% or 0.00% annual dividend contingent on the Company's income after income taxes. If the Company's income after income taxes is $1.0 million or greater, the dividend rate is 6.00%; if the Company's income after income taxes is less than $1.0 million, the dividend rate is 0.00%. This conversion will reduce the Company's liabilities by $2.5 million and increase its equity by $2.5 million. In addition, this conversion will reduce the Company's annual interest expense by $0.1 million. However, contingent on the after income tax income, this conversion could trigger the payment of an annual Preferred Stock dividend of $0.2 million or zero. If the $1.0 million after income tax income target is achieved, the Company's annual cash outflow would increase $0.1 million, or decrease $0.1 million if the $1.0 million after income tax income target is not achieved. This conversion is pending a shareholder vote on June 30, 2016 to amend the Company's Articles of Incorporation to allow for the issuance of Preferred Stock. The proposed amendment to the Company's Articles of Incorporation was approved by the Company's Board of Directors on January 18, 2016. This conversion will be consummated in July 2016.
