Note 8. Debt

The following is a summary of the Company's long-term indebtedness (in thousands):

On February 23, 2011, the Company amended and extended its Senior Credit Facility, extending its maturity to February 23, 2016 and increasing total capacity from $400 million to $700 million. The amended Senior Credit Facility provides a $600 million revolving credit facility, a $100 million term loan and a $300 million expansion option. Borrowings are subject to a pricing grid, which can result in increases or decreases to the borrowing spread, depending on the Company's leverage ratio, ranging from 1.25% to 2.50% in the case of loans bearing interest at LIBOR and from 0.25% to 1.25% in the case of loans bearing interest at the base rate. At May 31, 2011, the borrowing spread on LIBOR based borrowings was 2.00% (aggregating to 2.41% on outstanding term loan borrowings). In addition, a non-use fee is payable quarterly on the average unused credit line under the revolver ranging from 0.2% to 0.4% per annum. At May 31, 2011 the unused credit line under the revolver was $597.2 million, of which $454.3 million was available for borrowings. The new $100 million term loan will be repaid in quarterly installments of $1.25 million starting on March 31, 2012, increasing to $2.5 million per quarter beginning on March 31, 2013, with the remaining balance due at maturity. The Senior Credit Facility, which is secured by substantially all of the Company's domestic personal property assets, also contains customary limits and restrictions concerning investments, sales of assets, liens on assets, dividends and other payments. The two financial covenants included in the Senior Credit Facility agreement are a maximum leverage ratio of 3.75:1 and a minimum fixed charge coverage ratio of 1.50:1. The Company was in compliance with all debt covenants at May 31, 2011.

On June 12, 2007, the Company issued $250.0 million of 6.875% Senior Notes (the "Senior Notes") at an approximate $1.0 million discount, generating net proceeds of $249.0 million. The Senior Notes were issued at a price of 99.607% to yield 6.93%, and require no principal installments prior to their June 15, 2017 maturity. The $1.0 million initial issuance discount is being amortized through interest expense over the 10 year life of the Senior Notes. Semiannual interest payments on the Senior Notes are due in December and June of each year.

In November 2003, the Company issued $150.0 million of Senior Subordinated Convertible Debentures due November 15, 2023 (the "2% Convertible Notes"). Since 2003, the Company repurchased (for cash) $32.2 million of 2% Convertible Notes at an average price of 99.3% of par value. The remaining $117.8 million of 2% Convertible Notes, are convertible into 5,967,662 shares of Company's Class A common stock at a conversion rate of 50.6554 shares per $1,000 of principal amount, which equates to a conversion price of approximately $19.74 per share. The 2% Convertible Notes bear interest at a rate of 2.0% annually which is payable on November 15 and May 15 of each year. Beginning with the six-month interest period commencing May 16, 2011, holders also receive contingent interest as the trading price of the 2% Convertible Notes exceeded 120% of their underlying principal amount over a specified trading period, which effectively increases the interest rate from 2.0% to 2.7%. After November 2010, the Company may redeem all or part of the 2% Convertible Notes for cash at any time, at a redemption price equal to 100% of the principal amount, plus accrued interest. In addition, holders of the 2% Convertible Notes have the option to require the Company to repurchase all or a portion of their 2% Convertible Notes for cash on November 15, 2013 and November 15, 2018, at a repurchase price equal to 100% of the principal amount of the notes, plus accrued interest. Holders may also convert their 2% Convertible Notes into shares of the Company's Class A common stock prior to the scheduled maturity date.

In the third quarter of fiscal 2011, the Company entered into interest rate swap contracts that have a total notional value of $100.0 million and have maturity dates of March 23, 2016. The interest rate swap contracts pay the Company variable interest at the three month LIBOR rate, and the Company pays the counterparties a fixed interest rate of approximately 2.06%. These interest rate swap contracts were entered into to convert $100.0 million of the Senior Credit Facility borrowings into fixed rate debt. Based on the terms of the contracts and the underlying debt, the interest rate swap contracts were determined to be effective, and thus qualify as cash flow hedges. As such, any changes in the fair value of these interest rate swap contracts are recorded in accumulated other comprehensive loss on the accompanying Condensed Consolidated Balance Sheets. The fair value of these interest rate swap contracts was $1.3 million at May 31, 2011 and recognized in Other Long-term Liabilities.
