Transactions	Transactions Restructuring Plan On August 4, 2011, the Company’s board of directors approved a restructuring plan that included a significant organizational restructure and a cost savings and efficiency initiative. The Company initiated this restructuring plan in the third quarter of 2011. During the six months ended June 30, 2013, the Company recorded $3,363 related to restructuring charges, of which the Company recorded $2,608 in Selling, general and administrative expenses; $646 in Severance and related costs; and $109 in Cost of revenues, excluding depreciation and amortization. As of June 30, 2013, substantially all restructuring reserves have been paid. Amendment No. 2 to Existing Credit Facility In October 2012, the Company and its lenders entered into Amendment No. 2 to its existing credit facility that further modified the existing financial covenants. In connection with the execution of Amendment No. 2, the Company raised $30,000 from the sale of certain imaging assets, which the Company then leased from purchasers under competitive terms. The $30,000 in proceeds from the sale and lease transactions, was combined with $44,500 of cash on hand to make a total payment of $74,500 to permanently reduce borrowings outstanding under the term loan facility. The Company estimates it will incur $8,000 of annual rent payments in connection with the sale and lease transactions, which will reduce future Consolidated Adjusted EBITDA. Senior Secured Term Loan Refinancing On June 3, 2013, the Company replaced its existing credit facility with a new senior secured credit agreement with Credit Suisse AG, Cayman Islands Branch, as administrative agent, and the other lenders party thereto (the “New Credit Agreement”). The New Credit Agreement consists of (i) a $340,000, six-year term loan facility, (ii) a $50,000, five-year revolving loan facility, including a $20,000 sublimit for letters of credit, (iii) uncommitted incremental loan facilities of $100,000 of revolving or term loans, plus an additional amount if our pro forma leverage ratio is less than or equal to 3.25, subject to receipt of lender commitments and satisfaction of specified conditions, and (iv) an $80,000 delayed draw term loan facility, which must be drawn within thirty days of June 3, 2013. Upon the draw of the delayed draw term loan facility, the proceeds of which are required to be used to redeem a portion of the Company's $190,000 of 8% Senior Notes due 2016 (the “Notes”), such delayed draw term loan will convert into, and match the terms of, the new $340,000 term loan facility. If any of the Notes remain outstanding on September 1, 2016, then the maturity date of all loans under the New Credit Agreement will be September 1, 2016. Borrowings under the New Credit Agreement bear interest through maturity at a variable rate based upon, at the Company's option, either the London interbank offered rate ("LIBOR") or the base rate (which is the highest of the administrative agent’s prime rate, one-half of 1.00% in excess of the overnight federal funds rate, and 1.00% in excess of the one-month LIBOR rate), plus, in each case, an applicable margin. With respect to the term loan facilities, the applicable margin for LIBOR loans is 3.25% per annum, and with respect to the revolving loan facilities, the applicable margin for LIBOR loans ranges, based on the applicable leverage ratio, from 3.00% to 3.25% per annum, in each case, with a LIBOR floor of 1.00%. The applicable margin for base rate loans under the term loan facilities is 2.25% per annum and under the revolving loan facility ranges, based on the applicable leverage ratio, from 2.00% to 2.25% per annum. Prior to the refinancing of the term loan facilities, the applicable margin for base rate loans was 4.25% per annum and the applicable margin for revolving loans was 5.25% per annum, with a LIBOR floor of 2.00%. The Company is required to pay a commitment fee which ranges, based on the applicable leverage ratio, from 0.375% to 0.50% per annum on the undrawn portion available under the revolving loan facility and variable per annum fees with respect to outstanding letters of credit. During the first five and three-quarter years after the closing date, assuming that the Company draws the full amount of the delayed draw term loan facility, it will be required to make quarterly amortization payments of the term loans in the amount of $1,050. The Company is also required to make mandatory prepayments of term loans under the New Credit Agreement, subject to specified exceptions, from excess cash flow (as defined in the New Credit Agreement), and with the proceeds of asset sales, debt issuances and specified other events. Obligations under the New Credit Agreement are guaranteed by substantially all the Company's direct and indirect domestic subsidiaries. The obligations under the New Credit Agreement and the guarantees are secured by a lien on substantially all tangible and intangible property, and by a pledge of all of the shares of stock and limited liability company interests of the Company's direct and indirect domestic subsidiaries, of which the Company now owns or later acquires more than a 50% interest, subject to limited exceptions. In addition to other covenants, the New Credit Agreement places limits on the ability of the Company and its subsidiaries to declare dividends or redeem or repurchase capital stock, prepay, redeem or purchase debt, incur liens and engage in sale-leaseback transactions, make loans and investments, incur additional indebtedness, amend or otherwise alter debt and other material agreements, engage in mergers, acquisitions and asset sales, transact with affiliates and alter the business conducted by the Company and its subsidiaries. The New Credit Agreement also contains a leverage ratio covenant requiring the Company to maintain a maximum ratio of consolidated total debt to consolidated adjusted EBITDA expense that ranges from 4.95 to 1.00 to 4.30 to 1.00. For the quarter ending June 30, 2013, the New Credit Agreement requires a maximum leverage ratio of not more than 4.95 to 1.00. The New Credit Agreement eliminated the interest coverage ratio covenant which the Company was subject to maintain prior to the refinancing. Failure to comply with the covenants in the New Credit Agreement could permit the lenders under the New Credit Agreement to declare all amounts borrowed under the new credit agreement, together with accrued interest and fees, to be immediately due and payable, and to terminate all commitments under the New Credit Agreement. As a result of the transaction, the Company immediately recognized a loss on extinguishment totaling $17,069 resulting from the write-off of unamortized deferred financing costs and the discount related to the former credit facility. As of June 30, 2013, there was $337,921 outstanding under the new term loan facility and no borrowings under the new revolving credit facility. As of June 30, 2013, the Company’s ratio of consolidated total debt to Consolidated Adjusted EBITDA calculated pursuant to the New Credit Agreement was 3.70 to 1.00. On July 3, 2013, the Company redeemed $80,000 in principal amount of its Notes pursuant to the terms of the indenture governing the Notes, drawing the full amount of the delayed draw term loan facility. As a result of the redemption, $1,522 of unamortized deferred costs and associated discount were immediately expensed, as well as $3,200 for the related call premium.
