Long-Term Debt [Abstract]
LONG TERM DEBT	NOTE F – LONG TERM DEBT *Bank Credit Agreement* In connection with the Navilyst acquisition, we entered into a Credit Agreement with a group of banks which provided a $150 million senior secured term loan facility and a $50 million senior secured revolving credit facility. The $150 million in proceeds from the term loan were used to finance a portion of the consideration for the acquisition. The revolving facility may be used for general corporate purposes and was undrawn at November 30, 2012. Both facilities have five year maturities. The term facility has a quarterly repayment schedule equal to 5%, 5%, 15%, 25% and 50% of its principal amount in years one through five. The credit agreement contains certain financial covenants relating to fixed charge coverage and leverage, as defined, with which we were in compliance at November 30, 2012. Amounts borrowed under the Credit Agreement are collateralized by all our assets. Interest on both the term loan and the revolving loan is based on a base rate or Eurodollar rate plus an applicable margin with increases as our total leverage ratio increases, and with the base rate and Eurodollar rate have ranges of 1.0% to 1.75% and 2.0% to 2.75% respectively. In the event of default, the interest rate may be increased by 2.0%. The revolving facility will also carry a commitment fee of 0.30% to 0.50% per year on the unused portion. As of November 30, 2012, net deferred financing costs of $2.2 million are recorded as a component of other assets on the balance sheet and are being amortized over the remaining life of the related debt. In June 2012, we entered in an interest rate swap agreement, with an initial notional amount of $100 million, to limit the effect of rising of interest rates. The Swap Agreement, which qualifies for hedge accounting under authoritative guidance, is a contract to exchange floating interest rate payments for fixed interest rate payments on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement.

NOTE F – LONG TERM DEBT

Bank Credit Agreement

In connection with the Navilyst acquisition, we entered into a Credit Agreement with a group of banks which provided a $150 million senior secured term loan facility and a $50 million senior secured revolving credit facility. The $150 million in proceeds from the term loan were used to finance a portion of the consideration for the acquisition. The revolving facility may be used for general corporate purposes and was undrawn at November 30, 2012. Both facilities have five year maturities. The term facility has a quarterly repayment schedule equal to 5%, 5%, 15%, 25% and 50% of its principal amount in years one through five. The credit agreement contains certain financial covenants relating to fixed charge coverage and leverage, as defined, with which we were in compliance at November 30, 2012. Amounts borrowed under the Credit Agreement are collateralized by all our assets. Interest on both the term loan and the revolving loan is based on a base rate or Eurodollar rate plus an applicable margin with increases as our total leverage ratio increases, and with the base rate and Eurodollar rate have ranges of 1.0% to 1.75% and 2.0% to 2.75% respectively. In the event of default, the interest rate may be increased by 2.0%. The revolving facility will also carry a commitment fee of 0.30% to 0.50% per year on the unused portion.
