Debt Disclosure [Text Block] | 6. Debt and Credit Agreements On April 19, 2013, we entered into a Credit Agreement for a $20 million revolving line of credit maturing on April 19, 2017 with KeyBank National Association (“KeyBank”) and Stearns Bank National Association (“Stearns Bank”). On November 7, 2014, we entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”) with KeyBank to (i) increase the credit facility from $20 million to $35 million, and (ii) extend the maturity date of the credit facility to November 7, 2019. The credit facility is secured by our personal property and assets. Certain of our wholly owned subsidiaries have also guaranteed the credit facility. The entire $35 million under the credit facility was available at June 30, 2015. The interest rate under the Amended Credit Agreement is KeyBank’s prime rate or LIBOR, at our option, plus an applicable margin depending on our leverage ratio. The LIBOR margins range from 1.5% to 2.5% and the base rate margins range from 0.5% to 1.5%. Payments on the credit facility are interest only, payable quarterly with respect to each base rate loan and at varying times with respect to LIBOR rate loans, with outstanding principal and interest due at maturity. Prepayment is permitted at any time without penalty, subject to certain restrictions on the order of repayment or prepayment. We are obligated to pay a commitment fee at an annual rate of 0.175% to 0.350%, depending on our leverage ratio, times the unused total revolving commitment of the credit facility based on the average daily amount outstanding under the credit facility for the previous quarter. The commitment fee is payable quarterly in arrears. During the three months ended June 30, 2015 and 2014, we incurred gross interest expense of $49,000 and $64,000, consisting primarily of loan fee amortization of $21,000 and $26,000, respectively, and commitment fees of $22,000 and $21,000, respectively. During the six months ended June 30, 2015 and 2014, we incurred gross interest expense of $94,000 and $126,000, consisting primarily of loan fee amortization of $40,000 and $53,000, respectively, and commitment fees of $44,000 and $41,000, respectively. We capitalized $29,000 of interest costs during the six months ended June 30, 2014. Unamortized loan fees of $363,000 at June 30, 2015 are being amortized over the life of the credit facility and are included in other assets in the consolidated balance sheet. The credit facility also requires us to comply with certain covenants, including (a) a fixed charge coverage ratio of not less than 1.50 and (b) a maximum leverage ratio of 5.0 to 1.0 through March 31, 2016 and 4.75 to 1.0 from April 1, 2016 through the maturity date. We were in compliance with all covenants at June 30, 2015. |
