Senior Credit Facility

On July 8, 2011, the Company entered into a five-year, senior, secured revolving credit facility (the "Senior Credit Facility"). The Senior Credit Facility provides for a maximum of $900,000 of revolving credit, including limited amounts of credit in the form of letters of credit and swingline loans. The Company paid financing costs of $8,218 in connection with its Senior Credit Facility. These costs were deferred and, along with unamortized costs of $12,277 related to the Company's prior senior, secured revolving credit facility, are being amortized over the term of the Senior Credit Facility.

On January 20, 2012, the Company entered into an amendment to the Senior Credit Facility that provides for an incremental term loan facility in the aggregate principal amount of $150,000. The Company paid financing costs of $1,018 in connection with the amendment to its Senior Credit Facility. These costs were deferred and are being amortized over the remaining term of the Senior Credit Facility. The incremental term loan facility provides for eight scheduled quarterly principal payments of $1,875, with the first such payment due on June 30, 2012, followed by four scheduled quarterly principal payments of $3,750, with all remaining quarterly principal payments of $5,625 prior to maturity.

The Senior Credit Facility is scheduled to mature on July 8, 2016. The Company can terminate and prepay the Senior Credit Facility at any time without payment of any termination or prepayment penalty (other than customary breakage costs in respect of loans bearing interest at a rate based on LIBOR).

At the Company's election, revolving loans under the Senior Credit Facility bear interest at annual rates equal to either (a) LIBOR for 1-, 2-, 3- or 6- month periods, as selected by the Company, plus an applicable margin ranging between 1.25% and 2.0%, or (b) the higher of the Bank of America, N.A. prime rate, the Federal Funds rate plus 0.5%, and a monthly LIBOR rate plus 1.0%, plus an applicable margin ranging between 0.25% and 1.0%. The Company also pays a commitment fee to the lenders under the Senior Credit Facility on the average amount by which the aggregate commitments of the lenders exceed utilization of the Senior Credit Facility ranging from 0.25% to 0.4% per annum. The applicable margin and the commitment fee are determined based on the Company's Consolidated Net Leverage Ratio (with applicable margins and the commitment fee increasing as the ratio increases).

All obligations of the Company and the other borrowers under the Senior Credit Facility are required to be guaranteed by all of the Company's material domestic subsidiaries, and all obligations of borrowers that are foreign subsidiaries are guaranteed by those foreign subsidiaries of the Company which the Company designates as guarantors.

Due to the rating agency upgrade announced on March 14, 2012 by Standard & Poor's Financial Services, LLC ("S&P"), the security interests in domestic accounts receivable and inventories, certain shares of capital stock (or equivalent ownership interests) of the domestic borrowers' and domestic guarantors' subsidiaries, and proceeds of any of the foregoing securing obligations under the Senior Credit Facility were released. The Company will be required to reinstate such security interests if there is a ratings downgrade such that: (a) both (i) the Moody's Investors Service, Inc. ("Moody's") rating is Ba2 and (ii) the S&P rating is BB, (b) (i) the Moody's rating is Ba3 or lower and (ii) the S&P rating is below BBB- (with a stable outlook or better) or (c) (i) the Moody's rating is below Baa3 (with a stable outlook or better) and (ii) the S&P rating is BB- or lower.

The Senior Credit Facility includes certain affirmative and negative covenants that impose restrictions on the Company's financial and business operations, including limitations on liens, indebtedness, investments, fundamental changes, asset dispositions, dividends and other similar restricted payments, transactions with affiliates, payments and modifications of certain existing debt, future negative pledges, and changes in the nature of the Company's business. Many of these limitations are subject to numerous exceptions. The Company is also required to maintain a Consolidated Interest Coverage Ratio of at least 3.0 to 1.0 and a Consolidated Net Leverage Ratio of no more than 3.75 to 1.0, each as of the last day of any fiscal quarter, as defined in the Senior Credit Facility. The Senior Credit Facility also contains customary representations and warranties and events of default, subject to customary grace periods.

As of March 31, 2012, the amount utilized under the Senior Credit Facility including the term loan was $509,036 resulting in a total of $540,964 available under the Senior Credit Facility. The amount utilized included $411,700 of borrowings, $46,796 of standby letters of credit guaranteeing the Company's industrial revenue bonds and $50,540 of standby letters of credit related to various insurance contracts and foreign vendor commitments. As of April 16, 2012, subsequent to the repayment of the outstanding senior 7.20% notes discussed below, the amount utilized under the Senior Credit Facility including the term loan was $827,136.

Senior Notes

On January 17, 2006, the Company issued $900,000 aggregate principal amount of 6.125% notes due January 15, 2016. Interest payable on these notes is subject to adjustment if either Moody's or S&P, or both, upgrades or downgrades the rating assigned to the notes. Each rating agency downgrade results in a 0.25% increase in the interest rate, subject to a maximum increase of 1% per rating agency. If later the rating of these notes improves, then the interest rates would be reduced accordingly. Each 0.25% increase in the interest rate of these notes would increase the Company's interest expense by approximately $63 per quarter per $100,000 of outstanding notes. In 2009, interest rates increased by an aggregate amount of 75 basis points as a result of downgrades by Moody's and S&P. In the first quarter of 2012, interest rates decreased by 50 basis points as a result of the upgrades from S&P and Moody's. Any future downgrades in the Company's credit ratings could increase the cost of its existing credit and adversely affect the cost of and ability to obtain additional credit in the future.

In 2002, the Company issued $400,000 aggregate principal amount of its senior 7.20% notes due April 15, 2012. During 2011, the Company repurchased $63,730 of its senior 7.20% notes, at an average price equal to 102.72% of the principal amount. On April 16, 2012, the Company repaid the $336,300 principal amount of outstanding senior 7.20% notes, together with accrued interest of $12,106, at maturity using available borrowings under its Senior Credit Facility. As a result, the Company classified the outstanding senior 7.20% notes as long-term debt as of March 31, 2012.
