Debt	Note 10—Debt On November 30, 2011, Advent entered into a Credit Agreement (the "Credit Agreement") by and among Advent, the lenders party thereto (the "Lenders"), U.S. Bank National Association, as documentation agent, Wells Fargo Bank, National Association, as syndication agent, and JPMorgan Chase Bank, N.A., as administrative agent for the Lenders ("Agent"). The Credit Agreement provides for (i) a $50.0 million revolving credit facility, with a $25.0 million letter of credit sublimit and a $10.0 million swingline loan sublimit (the "Revolving Credit Facility"), (ii) a $50.0 million term loan facility (the "Term Loan A Facility"), and (iii) a $50.0 million delayed draw term loan facility (the "Delayed Draw Term Loan Facility" and, together with the Term Loan A Facility, the "Term Loan Facility"). Advent may request borrowings under the Revolving Credit Facility until November 30, 2016. The option to request borrowings under the Delayed Draw Term Loan Facility expired on November 30, 2012. The Credit Agreement also contains an increase option permitting Advent, subject to certain requirements, to arrange with the Lenders and/or new lenders for up to an aggregate of $50.0 million in additional commitments, which commitments may be for revolving loans or term loans. The proceeds of the loans made under the Credit Agreement may be used for general corporate purposes. The loans bear interest, at Advent's option, at the base rate plus a spread of 0.75% to 1.75% or an adjusted LIBOR rate (based on one, two, three or six-month interest periods) plus a spread of 1.75% to 2.75%, in each case with such spread being determined based on the consolidated leverage ratio for the preceding four fiscal quarter period and certain other factors. The base rate means the highest of JPMorgan Chase Bank, N.A.'s prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 1-month interest period plus a margin equal to 1.00%. Swing line loans accrue interest at a per annum rate based on the base rate plus the applicable margin for base rate loans. On November 30, 2011, Advent borrowed $50.0 million of term loans under the Term Loan A Facility and incurred approximately $1.9 million of debt issuance costs that have been deferred and will be amortized over the life of the agreement. On November 30, 2012, Advent borrowed $50.0 million of term loans under the Delayed Draw Term Loan Facility. As of December 31, 2012, the Company's outstanding debt balance was $95.0 million and is due in full no later than November 30, 2016. The obligations under the Credit Agreement are secured by substantially all of the assets of Advent. The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict Advent and its subsidiaries' ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, pay dividends or make distributions, make investments, make acquisitions, prepay certain indebtedness, enter into certain transactions with affiliates, enter into sale and leaseback transactions, enter into swap agreements and enter into restrictive agreements, in each case subject to customary exceptions for a credit facility of this size and type. Advent is also required to maintain compliance with a consolidated leverage ratio, a consolidated interest coverage ratio and a minimum level of liquidity. As of December 31, 2012, Advent was in compliance with all associated covenants. The Credit Agreement includes customary events of default that include among other things, non-payment defaults, defaults due to the inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, defaults due to an unenforceability of the security documents or guarantees, and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the Credit Agreement.
