Debt Disclosure [Abstract]
Line of Credit	Note L — Line of Credit In September 2014, the Company renewed a line of credit agreement. The line is with a financial institution to provide a revolving credit facility with borrowing capacity of up to $10 million. Borrowings under this agreement bear interest, at the Company’s option, at a fixed LIBOR-based rate plus 1.50% or at a fluctuating rate determined by the financial institution to be 1.50% above the daily one-month LIBOR rate. The loan covenants require the Company to maintain the current assets to liabilities ratio of at least 1.25:1, debt to tangible net worth not greater than 1.25:1 and have positive net income. The Company’s management believes it was in compliance with all of its loan covenants as of March 31, 2015. As of March 31, 2015, the Company had borrowed on the line of credit in the amount of $618,000, which was included in accrued liabilities on the balance sheet and was paid off on April 1, 2015. Letters of credit in the aggregate amount of $4.5 million have been issued separate from the line of credit and therefore do not reduce the amount of borrowings available under the revolving credit facility. The renewed credit agreement expires in September 2015.
