Loan Facilities—Bank

On May 18, 2012, the Company amended and restated its existing credit facility with CoBank, ACB (the “Amended Credit Facility”) providing for $275.0 million in two term loans and a revolver loan of up to $100.0 million (which includes a $10.0 million swingline sub-facility) and additional term loans up to an aggregate of $100.0 million, subject to lender approval.

On October 29, 2012, the Company further amended its Amended Credit Facility to provide for an additional letter of credit sub-facility to its revolver loan, to be available for issuance in connection with the Company’s Mobility Fund Grant obligations. Under the amendment, the Company has the ability to use up to $55 million of its revolving credit facility for the issuance of letters of credit and currently has approximately $29.9 million of such letters of credit outstanding which will accrue a fee at a rate of 1.75% per annum on the outstanding amounts. As of June 30, 2013, there were no draw downs against these letters of credit.

The term loan A-1 is $125 million and matures on June 30, 2017 (the “Term Loan A-1”). The term loan A-2 is $150 million and matures on June 30, 2019 (the “Term Loan A-2” and collectively with the Term Loan A-1, the “Term Loans”). Each of the Term Loans require certain quarterly repayment obligations. The revolver loan matures on June 30, 2017. The Company may prepay the Amended Credit Facility at any time without premium or penalty, other than customary fees for the breakage of London Interbank Offered Rate (LIBOR) loans.

Amounts borrowed under the Term Loan A-1 and the revolver loan bear interest at a rate equal to, at the Company’s option, either (i) LIBOR plus an applicable margin ranging between 2.00% to 3.50% or (ii) a base rate plus an applicable margin ranging from 1.00% to 2.50% (or, in the case of amounts borrowed under the swingline sub-facility, an applicable margin ranging from 0.50% to 2.00%). Amounts borrowed under the Term Loan A-2 bear interest at a rate equal to, at the Company’s option, either (i) the LIBOR plus an applicable margin ranging between 2.50% to 4.00% or (ii) a base rate plus an applicable margin ranging from 1.50% to 3.00%. The base rate is equal to the higher of (i) 1.50% plus the higher of (x) the one-week LIBOR and (y) the one-month LIBOR; and (ii) the prime rate (as defined in the Amended Credit Facility). The applicable margin is determined based on the ratio of the Company’s indebtedness (as defined in the Amended Credit Facility) to its EBITDA (as defined in the Amended Credit Facility).

Certain of the Company’s domestic subsidiaries, including our principal operating subsidiaries, are guarantors of the Company’s obligations under the Credit Agreement. Further, the Company’s obligations are secured by (i) a first priority, perfected lien on substantially all the property and assets of the Company and that of the guarantor subsidiaries, and (ii) a pledge of 100% of the Company’s equity interests in certain domestic subsidiaries and up to 65% of the equity interests outstanding of certain foreign subsidiaries, in each case, including the Company’s principal operating subsidiaries.

Borrowings as of June 30, 2013, after considering the effect of the interest rate swap agreements as described in Note 7, bore a weighted-average interest rate of 4.39%. Availability under the revolver loan, net of outstanding letters of credit of $29.9 million, was $70.1 million as of June, 2013.

Under the terms of the Amended Credit Facility, the Company must also pay a fee ranging from 0.25% to 0.50% of the average daily unused portion of the revolver loan over each calendar quarter, in which the fee is payable in arrears on the last day of each calendar quarter.

The Amended Credit Facility contains customary representations, warranties and covenants, including covenants by the Company limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. In addition, the Amended Credit Facility contains financial covenants by the Company that (i) impose a maximum leverage ratio of indebtedness to EBITDA, (ii) require a minimum debt service ratio of EBITDA to principal, interest and taxes payments and (iii) require a minimum ratio of equity to consolidated assets. As of June 30, 2013, the Company was in compliance with all of the financial covenants of the Amended Credit Facility.
