Notes Payable [Abstract]
Notes Payable	(5) Notes Payable: Credit Facilities — We have a $60.0 million credit facility that provides for availability until December 7, 2014 for working capital needs. The revolving line of credit bears interest at a variable rate equal to LIBOR or prime plus an applicable margin based on our leverage ratio, at our election. As of October 31, 2012, there were no borrowings outstanding. Had there been borrowings, they would have borne an interest rate of 4.5% per annum. As security for the credit facility, TD Bank, N.A. and the other lenders (the “Lenders”) thereunder have a first priority lien on all of our personal property and real estate assets. We may prepay, in whole or in part, any of the loans that have interest rates determined by reference to the prime rate, with interest accrued to the date of the prepayment on the amount prepaid, without any penalty or premium. Loans with a fixed rate of interest determined by reference to the LIBOR interest rate may be prepaid provided that we reimburse the Lenders for any costs associated with (i) our making payments on dates other than those specified in the credit agreement, or (ii) our borrowing or converting a LIBOR loan on a date other than the borrowing or conversion dates specified in the credit agreement. Convertible Notes — On December 15, 2006, we issued an aggregate of $80.0 million of 4% senior convertible notes (the “Convertible Notes”) maturing on December 15, 2026 to qualified institutional buyers pursuant to the terms and conditions of a securities purchase agreement and indenture. In fiscal 2011, we exchanged a total of $50.0 million of Convertible Notes for $50.0 million of Senior Notes (as defined below). During fiscal 2012, we repurchased the remaining $30.0 million of Convertible Notes utilizing cash on hand. As of October 31, 2012, there were no outstanding Convertible Notes. Senior Notes — During fiscal 2011, we issued an aggregate of $50.0 million of 9.5% senior notes due January 14, 2016 (“Senior Notes”) in exchange for $50.0 million of Convertible Notes pursuant to the terms and conditions of an exchange agreement and indenture (the “Senior Notes Indenture”). During the six months ended October 31, 2012, we repurchased a total of $6.4 million of our Senior Notes in the open market utilizing cash on hand. We paid $552,000 of interest relating to these purchases. The Senior Notes bear interest at a rate of 9.5% per annum payable on June 15 and December 15 of each year. The Senior Notes are general, unsecured obligations of our company. The Senior Notes Indenture contains certain affirmative and negative covenants, including limitations on restricted payments, limitations on indebtedness, limitations on the sale of assets, and limitations on liens. The limitation on indebtedness in the Senior Notes Indenture is only applicable at such time that the consolidated coverage ratio (as set forth in the Senior Notes Indenture) for us and our restricted subsidiaries is less than 2.00 to 1.00. In general, as set forth in the Senior Notes Indenture, the consolidated coverage ratio is determined by comparing our prior four quarters’ consolidated EBITDA (earnings before interest, taxes, depreciation, and amortization) to our consolidated interest expense. The credit agreement with the Lenders contains financial covenants relating to maintaining maximum leverage and minimum debt service coverage. The Senior Notes Indenture contains a financial covenant relating to times interest earned. We were in compliance with all debt covenants as of October 31, 2012.
