On May 31, 2012 the Company entered into a credit agreement which provides for a $300,000 five-year revolving multi-currency credit facility which includes provisions for the issuance of standby letters of credit, a $10,000 sublimit for swingline loans and a $25,000 sublimit letter of credit facility. The credit facility refinanced existing debt and closing costs of $96,550 and financed the acquisition of Quebec Silicon of $31,800. The credit facility currently provides an additional $171,800 of borrowing capacity. At the Company's election, the credit facility may be increased from time to time by an amount up to $125,000 in the aggregate; such increase may be in the form of term loans or increases in the revolving credit line. The agreement contains provisions for adding domestic and foreign subsidiaries of the Company as additional borrowers under the credit facility. The agreement terminates on May 31, 2017 and requires no scheduled prepayments before that date. The Company classifies borrowings under this credit facility as long-term liabilities.
 
Interest on borrowings under the credit agreement is payable, at the Company's election, at either (a) a base rate (the higher of (i) the U.S. federal funds rate plus 0.50% per annum, (ii) the Administrative Agent's prime rate or (iii) an adjusted London Interbank Offered Rate for loans with a one month interest period plus 1.00% per annum plus a margin ranging from 0.75% to 1.50% per annum (such margin determined by reference to the leverage ratio set forth in the credit agreement), or (b) the adjusted London Interbank Offered Rate plus a margin ranging from 1.75% to 2.50% per annum (such margin determined by reference to the leverage ratio set forth in the credit agreement). Certain commitment fees are also payable under the credit agreement. The credit agreement contains various covenants. They include, among others, a maximum total debt to earnings before income tax, depreciation and amortization ratio, a minimum interest coverage ratio and a maximum capital expenditures covenant. The credit facility is guaranteed by certain of the Company's domestic subsidiaries (the "Guarantors"). Borrowings under the credit agreement are collateralized by substantially all of the assets of the Company and the Guarantors, including certain real property, equipment, accounts receivable and inventory and the stock of certain of the Company's and the Guarantors' subsidiaries.

The Company was in compliance with the loan covenants at June 30, 2012, except as related to restrictions on capital expenditures. The Company received a waiver for the restriction limiting capital expenditures for the fiscal year ended June 30, 2012.

On October 1, 2010, the Company entered into a $15,000 revolving credit facility, and utilized proceeds from borrowings under the revolving credit facility to repay the Company's $5,880 short-term notes payable to Dow Corning. On March 5, 2012, the Company entered into an agreement to amend the Company's existing revolving credit facility. The amended agreement provides for a $20,000 revolving credit facility. Total borrowings under this revolving credit facility were $9,000 at June 30, 2012. Interest on advances under the revolving credit facility accrues at LIBOR plus an applicable margin percentage or, at the Company's option, prime plus an applicable margin percentage. The credit facility is subject to certain restrictive and financial covenants, which include limits on additional debt, a maximum ratio of debt to earnings before interest, taxes, depreciation and amortization and minimum net worth. The Company was in compliance with the loan covenants at June 30, 2012. The Company classifies borrowings under this revolving credit facility as current liabilities as the arrangement is payable in full upon the earlier of 10 business days following written demand by the lender or the agreement's expiration on June 30, 2013.

The Company's subsidiary, Quebec Silicon, entered into a revolving credit agreement dated October 1, 2010 and amended on November 23, 2011, which provides for up to $15,000 Canadian Dollars to fund Quebec Silicon's working capital requirements. Funding under the revolving credit agreement is available upon request at any time, up to the full amount of the unused credit commitment and subject to continued compliance. Interest on borrowings under the credit agreement is payable at a variable rate of Canadian prime plus 2.00% (5.00% at June 30, 2012), payable quarterly. The credit agreement expires on October 1, 2013, and may be terminated earlier, at the lender's discretion. All of Quebec Silicon's assets, properties and revenues have been pledge as security for Quebec Silicon's obligations under the revolving credit agreement. As of June 30, 2012, $3,223 ($3,304 Canadian Dollars) was outstanding under the facility.

On March 30, 2011, certain of the Company's domestic subsidiaries (the Borrowers) entered into an agreement to amend and restate the Company's existing senior credit facility and senior term loan. The amended and restated senior credit agreement provides for a $90,000 revolving credit facility, subject to a defined borrowing base, and matures on March 30, 2014. This facility includes a provision for the issuance of standby letters of credit and a $10,000 sublimit for swingline loans. The facility may be increased from time to time by an amount up to $10,000 in the aggregate at the Company's election, subject to approval by the existing or additional lenders. Interest on borrowings under the credit agreement is payable, at the Company's election, at either a base rate (the higher of the U.S. federal funds rate plus 0.50% per annum and the issuing bank's "prime rate") plus a margin of 1.50% per annum, or LIBOR plus a margin of 2.25% per annum. Certain commitment fees are also payable under the credit agreement. The facility is guaranteed by certain of the Borrowers' subsidiaries, and borrowings under the credit agreement are collateralized by the Borrowers' cash and cash equivalents, accounts receivable, and inventories, and the stock of their subsidiaries. Outstanding balances on this term loan were paid down and refinanced with the revolving multi-currency credit facility the Company entered into on May 31, 2012.
