Long-Term Debt
Long-Term Debt	9. Long-Term Debt The Company's Senior Secured Revolving Facility (the "Facility") provides for an aggregate availability up to $50 million with a $10 million sub-limit for letters of credit, subject to satisfaction of borrowing base requirements based on eligible domestic and foreign accounts receivable. The facility matures on March 14, 2014 and prior to each anniversary date, the Company can request one-year extensions, subject to lender consent. Borrowings under the Facility bear interest, at the election of the Company, at the London Interbank Offered Rate ("LIBOR") plus applicable margin or the base rate plus applicable margin. The base rate is the highest of (i) the published prime rate, (ii) the federal funds rate plus 0.50%, or (iii) one month LIBOR plus 2.0%. The applicable margin is based on a percentage per annum determined in accordance with a specified pricing grid based on (a) the total funded debt ratio of the Company and (b) with respect to LIBOR loans, whether such LIBOR loans are cash collateralized. For cash collateralized LIBOR loans, the applicable margin will range from 0.65% to 3.15% per annum. For LIBOR loans that are not cash collateralized and for based rate loans, the applicable margin will range from 1.50% to 4.50% per annum (if using LIBOR) and from 1.50% to 4.75% per annum (if using base rate). The Company pays quarterly commitment fees of 0.25% to 0.50% on the Facility's unused commitments based on the Company's leverage ratio. The Facility is secured by substantially all of the assets of the Company's domestic subsidiaries and 65% of the equity interest in all the first tier foreign subsidiaries. The financial covenants include a maximum consolidated leverage ratio, a minimum consolidated fixed charge coverage ratio and a minimum $30 million in unrestricted cash and/or marketable securities after taking into account the accrual for employee compensation and benefits. As of July 31, 2011 and April 30, 2011, the Company had no borrowings under its Facility; however, we are required to maintain $10.0 million on account with the lender, which provides collateral for the standby letters of credit and potential future borrowings. This amount is included in long-term investments and other assets in the consolidated balance sheets as of July 31, 2011 and April 30, 2011. At July 31, 2011 and April 30, 2011, there was $2.9 million of standby letters of credit issued under this Facility.
