Debt [Abstract]
Debt	Note 7. Debt Revolving Credit Facility On June 17, 2011, the Company entered into an unsecured credit agreement with Bank of America, N.A. (“Bank of America”). The agreement consisted of a $75.0 million three-year revolving credit facility. Under the terms of the credit facility agreement, the Company may initiate loans in U.S. dollars or in foreign currencies from time to time during the three-year period, which was set to expire on June 17, 2014. Per the terms of the agreement, all loans denominated in U.S. dollars will accrue interest at the bank’s Prime rate or at LIBOR plus a predetermined margin and all loans denominated in foreign currencies will accrue interest at LIBOR plus the same predetermined margin (together with any applicable mandatory liquid asset costs imposed by non-U.S. banking regulatory authorities). Interest on outstanding loans is due and payable on a quarterly basis through the credit facility maturity date. The Company may also borrow against the credit facility through the issuance of standby letters of credit. Outstanding letters of credit are subject to a fee equal to a predetermined percent per annum applied to amounts available to be drawn on outstanding letters of credit. The Company will also incur commitment fees for the credit facility at a predetermined annual rate which will be applied to the portion of the total credit facility commitment that has not been borrowed until outstanding loans and letters of credit exceed one half the total amount of the credit facility. On January 7, 2013, the Company entered into a first amendment (the “Amendment”) to this existing unsecured credit agreement with Bank of America. The Amendment extends the maturity date of the revolving credit facility for five years and increases the revolving commitment to an amount not to exceed $125.0 million. The new maturity date for the revolving credit facility per the Amendment is January 7, 2018. In addition, per the terms of the Amendment, the LIBOR margin decreased from 0.90 to 0.85 percent, the letter of credit fee decreased from 0.90 to 0.85 percent per annum and the commitment fee decreased from an annual rate of 0.15 percent to 0.12 percent. The Company incurs commitment fees applied to the portion of the total credit facility commitment that has not been borrowed until outstanding loans and letters of credit exceed $62.5 million. To date, the Company has used the proceeds of the revolving credit facility for its stock repurchases and plans to continue using such proceeds for its general working capital needs and stock repurchases under any existing board approved share buy-back plans. The agreement includes representations, warranties and covenants customary for credit facilities of this type, as well as customary events of default and remedies. The agreement also requires the Company to maintain minimum consolidated EBITDA of $40.0 million, measured on a trailing twelve month basis, at each reporting period. During the three months ended November 30, 2014, there were no additional borrowings against the revolving credit facility. The Company regularly converts existing draws on its line of credit to new draws with new maturity dates and interest rates. The balances on these draws and conversions have remained within a short-term classification due to certain contractual clauses included in its line of credit agreement with Bank of America. As of November 30, 2014, the Company had a $98.0 million outstanding balance on the revolving credit facility and was in compliance with all debt covenants under this credit facility.
