Financing Arrangements	Note 5 — Financing Arrangements We have a committed revolving credit agreement with a group of financial institutions in the amount of $200.0 million, expiring in May 2017 (Revolving Credit Agreement). The available line of credit on the Revolving Credit Agreement is reduced by any letters of credit issued under the agreement. As of March 31, 2013, there were borrowings of $25.0 million outstanding under this agreement. Our borrowings under the Revolving Credit Agreement bear interest at a variable rate (1.6% at March 31, 2013). In addition, there were letters of credit outstanding under the Revolving Credit Agreement totaling $43.6 million, which reduce the available line of credit to $131.4 million. We have a secured letter of credit facility agreement with a bank (Secured Letter of Credit Facility) which expires in March 2014. At March 31, 2013, there were letters of credit outstanding under this agreement of $60.5 million. In support of the Secured Letter of Credit Facility, we placed $68.8 million of our cash on deposit in the U.K. as collateral in a restricted account with the bank providing the facility. We are required to leave the cash in the restricted account so long as the bank continues to maintain associated letters of credit under the facility. The maximum amount of letters of credit currently allowed by the facility is $62.6 million, and any increase above this amount would require bank approval and additional restricted funds to be placed on deposit. We may choose at any time to terminate the facility and move the associated letters of credit to another credit facility. Letters of credit outstanding under the Secured Letter of Credit Facility do not reduce the available line of credit available under the Revolving Credit Agreement. On March 12, 2013, we entered into a note purchase and private shelf agreement pursuant to which we agreed to issue $100.0 million of senior unsecured notes, bearing interest at a rate of 3.35% and maturing on March 12, 2025. Notes with an aggregate principal amount of $50.0 million were purchased on March 12, 2013. Notes with the remaining aggregate principal amount of $50.0 million were purchased on April 23, 2013. In addition, pursuant to the agreement, we may from time to time issue and sell, and the purchasers may in their sole discretion purchase, within the next three years, additional senior notes in aggregate principal amount of up to $25.0 million that will have terms, including interest rate, as we and the purchasers may agree upon at the time of issuance.
