Debt Disclosure [Abstract]
Line of Credit	(17) Line of Credit The Company has a $10 million revolving line of credit available for ongoing working capital requirements, business acquisitions or general corporate purposes as needed. This line of credit is scheduled to expire on August 30, 2017. Any borrowings made under this line of credit bear interest at either a fluctuating base rate equal to the highest of (i) the Prime Rate, (ii) 1.50% above the daily one month LIBOR, and (iii) the Federal Funds Rate in effect plus 1.50% or at a fixed rate of LIBOR plus an agreed upon margin of between 0% and 2.25%, based on the Company’s funded debt to EBITDA ratio as defined in the agreement. In addition, the new agreement provided for two financial covenant requirements, namely, Total Funded Debt to Adjusted EBITDA (as defined) of not greater than 3 to 1 and a Fixed Charge Coverage Ratio (as defined) of not less than 1.25 to 1, both measured at the end of each quarter on a rolling four quarter basis. As of April 30, 2016, there have been no borrowings against this line of credit and the Company was in compliance with its financial covenants.
