During the first quarter of fiscal 2012, the non-recourse note due July 19, 2012 became fully recourse to the Company and is presented in the recourse portion of the table above.

During the three-month period ended August 31, 2010, we retired $6,000 par value of our 2.25% convertible notes due March 1, 2016.  The notes were retired for $4,667 cash, and the gain of $97, after consideration of unamortized discount and debt issuance costs, is recorded in gain on extinguishment of debt on the condensed consolidated statements of income.

At August 31, 2011, the face value of our long-term recourse debt was $447,713 and the estimated fair value was approximately $442,000.  The fair value was estimated using available market information.

Convertible Notes

On June 1, 2009, we adopted a new accounting standard that clarifies the accounting for convertible debt instruments that may be settled wholly or partly in cash when converted, and requires convertible debt to be accounted for as two components: (i) a debt component which is recorded upon issuance at the estimated fair value of a similar straight-debt instrument without the debt-for-equity conversion feature; and (ii) an equity component that is included in capital surplus and represents the estimated fair value of the conversion feature at issuance.  The bifurcation of the debt and equity components results in a discounted carrying value of the debt component compared to the principal amount.  The discount is accreted to the carrying value of the debt component through interest expense over the expected life of the debt using the effective interest method.

As of August 31, 2011 and May 31, 2011, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

	August 31,			May 31,
	2011			2011
Long-term debt:
Principal amount	$	268,380		$	268,380
Unamortized discount	(33,013		)	(36,233		)
Net carrying amount	$	235,367		$	232,147
Equity component, net of tax	$	74,966		$	74,966

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 August 31, 2011 and 2010, 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:
