Amounts outstanding under the Credit Facility bear interest at an annual rate equal to, at the Company’s option, either LIBOR for interest periods of one, two, three or six months or an alternate base rate (as defined in the Credit Facility agreement), plus, in each case, an applicable margin, that ranges from 0.75% to 2.25%. Under the terms of the Credit Facility, the Company is also required to pay certain fees, including an annual commitment fee that ranges from 0.30% to 0.45% on undrawn amounts and a letter of credit participation fee at an annual rate equal to the applicable margin as well as any applicable fronting fees, each of which is payable quarterly in arrears. The credit agreement governing the Credit Facility contains customary restrictive covenants on the Company and its subsidiaries. Restrictive covenants in the credit agreement include, but are not limited to: prohibitions on creating, incurring or assuming any liens; entering into merger arrangements; selling, leasing, transferring or otherwise disposing of assets; making a material change in the nature of the business; entering into transactions with affiliates; and incurring indebtedness through the subsidiaries. Many of these restrictions are subject to certain minimum thresholds and exceptions. Financial covenants under the credit agreement include: (i) the quarterly maintenance of a leverage ratio (total debt to adjusted EBITDA), as defined in the credit agreement, of not greater than 3.00:1.00, and (ii) a minimum interest coverage ratio (EBITDA to interest expense) for the four consecutive fiscal quarters ended before the date of determination) of not less than 4.00:1.00. The credit agreement governing the Credit Facility also contains customary provisions regarding events of default which could result in an acceleration or increase in amounts due, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of a representation or warranty, bankruptcy or insolvency proceedings, change of control, certain judgments, ERISA matters, cross-default to other debt agreements, governmental action prohibiting or restricting the company or its subsidiaries in a manner that has a material adverse effect and failure of certain guaranty obligations. The lenders (and their respective affiliates) may have provided, and may in the future provide, investment banking, cash management, underwriting, lending, commercial banking, leasing, foreign exchange, trust or other advisory services to the company and its subsidiaries and affiliates. These parties may have received, and may in the future receive, customary compensation for these services. Debt Financing Commitment In connection with the Merger Agreement, on December 16, 2016, the Company entered into a debt financing commitment letter (the "Commitment Letter") with Barclays Bank PLC and Morgan Stanley Senior Funding, Inc. (the “Initial Commitment Parties”). Pursuant to the Commitment Letter, the Initial Commitment Parties committed to arrange and provide the Company with a senior secured credit facility ("Loan Facility") composed, as of March 31, 2017, of (i) a term loan of up to $260.0 million with an expected maturity of seven years from the execution date and (ii) a revolving credit facility of up to $100.0 million maturing five years after the execution date. On March 2, 2017, the Company priced a $260.0 million first-lien term loan with a seven year tenor. The loan was priced with 0.50% of upfront fees and a spread of LIBOR plus 3.75% (LIBOR floor of 0.75%). The spread steps down to LIBOR plus 3.50% at net leverage levels of less than 1.0. The term loan will be drawn down at the closing date for the Proposed Acquisition. A delayed draw fee is in place for the period between pricing of the term loan on March 2, 2017 and the closing date of the Proposed Acquisition. In addition, the Company priced a $100.0 million, five year revolving credit facility at a spread of LIBOR plus 3.75% (LIBOR floor is 0.00%). The availability of borrowings under the term loan and revolving credit facility are subject to satisfaction of certain customary conditions which include termination and repayment of all amounts outstanding under our existing senior unsecured revolving credit facility (using cash on hand). The term loan and revolving credit facility will contain affirmative and negative financial and operating covenants and events of default customary for facilities of this type. The term loan and revolving credit facility will be guaranteed by the Company's domestic subsidiaries (subject to certain exceptions) and will be secured by substantially all of the Company's assets.
