Notes to Financial Statements
Dividends [Text Block]	8. Dividends In 2010, we announced that our Board of Directors approved a regular cash dividend program to our stockholders, subject to approval each quarter. Quarterly cash dividends of $0.025 per share of common stock were declared in each quarter of 2015 and 2014 and totaled $3.3 million annually for each of 2015 and 2014. Quarterly cash dividends of $0.017 per share were declared in each of the first and second quarters of 2013, and of $0.025 per share were declared in each of the third and fourth quarters of 2013, totaling $2.8 million. Our ability to pay cash dividends is currently limited by restrictions contained in our revolving credit facility, which prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of 25% of our net income from the prior fiscal year. A waiver of the 25% limitation for 2015 and 2016, should it apply, was obtained from the lender.
