Credit Facility and Long Term Debt	Credit Facility and Other Long Term Debt Credit Facility In March 2015, the Company amended its existing credit agreement, providing an additional $150.0 million of term loan borrowings, which were borrowed on the closing date of the amendment, resulting in aggregate term loan borrowings under the credit agreement of $400.0 million. This amendment also increased revolving credit facility commitments available under the credit agreement from $400.0 million to $800.0 million, of which the Company borrowed $250.0 million on the closing date of the amendment. These additional borrowings were used to fund, in part, the acquisition of MFP. At the Company's request and the lenders' consent, revolving and/or term loan borrowings may be increased by up to $300.0 million in aggregate, subject to certain conditions as set forth in the credit agreement, as amended. Incremental borrowings are uncommitted and the availability thereof will depend on market conditions at the time the Company seeks to incur such borrowings. Borrowings under the revolving credit facility may be made in U.S. Dollars, Euros, Pounds Sterling, Japanese Yen and Canadian Dollars. Up to $50.0 million of the facility may be used for the issuance of letters of credit and up to $50.0 million of the facility may be used for the issuance of swingline loans. There were no significant letters of credit or swingline loans outstanding as of June 30, 2015. The credit agreement contains negative covenants that, subject to significant exceptions, limit the ability of the Company and its subsidiaries to, among other things, incur additional indebtedness, make restricted payments, pledge their assets as security, make investments, loans, advances, guarantees and acquisitions, undergo fundamental changes and enter into transactions with affiliates. The Company is also required to maintain a ratio of consolidated EBITDA, as defined in the credit agreement, to consolidated interest expense of not less than 3.50 to 1.00 and is not permitted to allow the ratio of consolidated total indebtedness to consolidated EBITDA to be greater than 3.25 to 1.00 ("consolidated leverage ratio"). As of June 30, 2015, the Company was in compliance with these ratios. In addition, the credit agreement contains events of default that are customary for a facility of this nature, and includes a cross default provision whereby an event of default under other material indebtedness, as defined in the credit agreement, will be considered an event of default under the credit agreement. Borrowings under the credit agreement bear interest at a rate per annum equal to, at the Company’s option, either (a) an alternate base rate, or (b) a rate based on the rates applicable for deposits in the interbank market for U.S. Dollars or the applicable currency in which the loans are made (“adjusted LIBOR”), plus in each case an applicable margin. The applicable margin for loans will be adjusted by reference to a grid (the “Pricing Grid”) based on the consolidated leverage ratio and ranges between 1.00% to 1.25% for adjusted LIBOR loans and 0.00% to 0.25% for alternate base rate loans. The weighted average interest rates under the initial term loan, delayed draw term loan, new term loan and revolving credit facility were 1.31% during the three months ended June 30, 2015, and 1.25%, 1.25%, 1.31% and 1.31% during the six months ended June 30, 2015, respectively.
