Long-term debt consists of the following:

	October 31, 2013		April 30, 2013
4.78% Senior Notes due June 1, 2014	$	100.0	$	100.0
6.12% Senior Notes due November 1, 2015		24.0		24.0
6.63% Senior Notes due November 1, 2018		393.5		395.0
3.50% Senior Notes due October 15, 2021		766.1		748.8
5.55% Senior Notes due April 1, 2022		350.0		350.0
4.50% Senior Notes due June 1, 2025		400.0		400.0
Total long-term debt	$	2,033.6	$	2,017.8
Current portion of long-term debt		150.0		50.0
Total long-term debt, less current portion	$	1,883.6	$	1,967.8

The 3.50 percent Senior Notes were issued in a public offering and the remaining Senior Notes were privately placed. The Senior Notes are unsecured and interest is paid semiannually. Scheduled payments are required on the 5.55 percent Senior Notes, of which $50.0 is due on April 1, 2014, and on the 4.50 percent Senior Notes, the first of which is $100.0 due on June 1, 2020. The $100.0 balance of the 4.78 percent Senior Notes is due on June 1, 2014. We may prepay at any time all or part of the Senior Notes at 100 percent of the principal amount thereof, together with accrued and unpaid interest, and any applicable make-whole amount.

Interest paid totaled $22.8 and $26.7 for the three months ended October 31, 2013 and 2012, respectively, and $45.2 and $48.9 for the six months ended October 31, 2013 and 2012, respectively. This differs from interest expense due to the timing of payments, amortization of fair value adjustments, amortization of debt issue costs, and interest capitalized.

In the second quarter of 2014, we entered into an interest rate swap, with a notional amount of $750.0, on the 3.50 percent Senior Notes due October 15, 2021, converting the Senior Notes from a fixed to a variable rate basis. The interest rate swap was designated as a fair value hedge of the underlying debt obligation. At October 31, 2013, a net gain from changes in the fair value of the interest rate swap of $17.2 was recognized in interest expense with a corresponding offset due to changes in the fair value of the hedged underlying debt, resulting in no net impact to interest expense. For additional information, see Note 11: Derivative Financial Instruments.

On September 6, 2013, we entered into an amended and restated credit agreement with a group of eleven banks. The credit facility, which amends and restates our $1.0 billion credit agreement dated as of July 29, 2011, provides for a revolving credit line of $1.5 billion and extends the maturity to September 6, 2018. Borrowings under the revolving credit facility bear interest based on the prevailing U.S. Prime Rate, Canadian Base Rate, London Interbank Offered Rate (“LIBOR”), or Canadian Dealer Offered Rate, based on our election. Interest is payable either on a quarterly basis or at the end of the borrowing term. At October 31, 2013, we had a balance outstanding under the revolving credit facility of $207.0 at a weighted-average interest rate of 1.10 percent.

Our debt instruments contain certain financial covenant restrictions including consolidated net worth, a leverage ratio, and an interest coverage ratio. We are in compliance with all covenants.
