During the six-month period ended November 30, 2012, we repurchased $6.4 million par value of our 1.625% convertible notes due March 1, 2014, $5.5 million par value of our 2.25% convertible notes due March 1, 2016 and $11.0 million par value of our 1.75% convertible notes due February 1, 2026. The 1.625% notes, 2.25% notes and 1.75% notes were repurchased for $6.1 million, $4.9 million and $11.0 million cash, respectively, with a total loss of $0.3 million, after consideration of unamortized discount and debt issuance costs. The losses on the debt repurchases for the 1.625%, 2.25% and 1.75% convertible notes are recorded in Loss on extinguishment of debt on the condensed consolidated statements of income. During the six-month period ended November 30, 2012, we paid $8.4 million principal amount of our 7.22% debt due July 19, 2012. At November 30, 2012, the face value of our debt was $794.2 million and the estimated fair value was approximately $793.1 million. The fair value amounts of our long-term debt securities are estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. The debt is classified as Level 2 in the fair value hierarchy. We are subject to a number of covenants under our financing arrangements, including restrictions which related to the payment of cash dividends, maintenance of minimum net working capital and tangible net worth levels, fixed charge coverage ratio, sales of assets, additional financing, purchase of our shares and other matters. We are in compliance with all financial covenants under our financing arrangements. On December 20, 2012, we commenced an offer to exchange the outstanding unregistered 7.25% Senior Notes due 2022, which were issued in an exempt offering on January 23, 2012, for substantially identical notes that have been registered under the Securities Act of 1933. These notes are now fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by substantially all of our existing domestic and foreign subsidiaries. Convertible Notes As of November 30, 2012 and May 31, 2012, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:
|  | November 30, |  | May 31, |
|  | 2012 |  | 2012 |
Long-term debt: |  |  |  |  |
Principal amount |  | $ | 206.4 |  | $ | 229.3 |
Unamortized discount |  | (12.4 | ) | (19.8 | )
Net carrying amount |  | $ | 194.0 |  | $ | 209.5 |
Equity component, net of tax |  | $ | 74.8 |  | $ | 74.8 |
The discount on the liability component of long-term debt is being amortized using the effective interest method based on an effective rate of 8.48% for our 1.75% convertible notes; 6.82% for our 1.625% convertible notes and 7.41% for our 2.25% convertible notes. For our 1.75% convertible notes, the discount is being amortized through February 1, 2013, which is the first put date for those notes. For our 1.625% and 2.25% convertible notes, the discount is being amortized through their respective maturity dates of March 1, 2014 and March 1, 2016. As of November 30, 2012 and 2011, for each of our convertible note issuances, the “if converted” value does not exceed its principal amount. The interest expense associated with the convertible notes was as follows:
|  | Three Months Ended |  | Six Months Ended |
