Summary of the 2014 Credit Facility

In February 2014, we entered into a five-year $325.0 million credit facility (the “2014 Credit Facility”) and drew $175.0 million on a term loan upon closing, which was used to repay all amounts outstanding under the 2012 Credit Facility.

The 2014 Credit Facility includes the following facilities: (i) a dollar and a designated currency revolving credit facility with sublimits for letters of credit and swingline loans (the “2014 Revolving Facility”) and (ii) a term loan facility (the “2014 Term Loan”).

In connection with our entry into the 2014 Credit Facility, we paid $2.5 million in financing costs, of which $1.1 million were capitalized and, together with a portion of the unamortized deferred financing costs from prior facilities, are being amortized into interest expense over the term of the new facility using the effective interest method. As of June 30, 2016 and December 31, 2015, deferred financing costs totaling $0.7 million and $0.9 million, respectively, were included in other assets on the consolidated balance sheet.

The 2014 Credit Facility is secured by the stock and limited liability company interests of certain of our subsidiaries and is guaranteed by our material domestic subsidiaries.

Amounts borrowed under the dollar tranche revolving credit loans and term loan under the 2014 Credit Facility bear interest at a rate per annum equal to, at our option, (a) a base rate equal to the highest of (i) the prime rate, (ii) federal funds rate plus 0.50% and (iii) one month LIBOR plus 1.00% (the “Base Rate”), in addition to a margin of 0.00% to 0.50%, or (b) LIBOR rate plus a margin of 1.00% to 1.50%.

We also pay a quarterly commitment fee on the unused portion of the 2014 Revolving Facility from 0.15% to 0.225% per annum, depending on our net leverage ratio. At June 30, 2016, the commitment fee was 0.225%.

The 2014 Term Loan requires periodic principal payments. The balance of the 2014 Term Loan and any amounts drawn on the 2014 Revolving Facility are due upon maturity of the 2014 Credit Facility in February 2019. We evaluate the classification of our debt as current or non-current based on the required annual maturities of the 2014 Credit Facility.

The 2014 Credit Facility includes financial covenants related to the net leverage ratio and interest coverage ratio, as well as restrictions on our ability to declare and pay dividends and our ability to repurchase shares of our common stock. At June 30, 2016, we were in compliance with our debt covenants under the 2014 Credit Facility.

Financing for MicroEdge acquisition

The 2014 Credit Facility includes an option to request increases in the revolving commitments and/or request additional term loans in an aggregate principal amount of up to $200.0 million. On October 1, 2014, we exercised this option, and certain lenders agreed, to increase the revolving credit commitments by $100.0 million (the "October 2014 Additional Revolving Credit Commitments") such that for the period commencing October 1, 2014, the aggregate revolving credit commitments available were $250.0 million. The October 2014 Additional Revolving Credit Commitments have the same terms as the existing revolving credit commitments.

On October 1, 2014, we drew down a $140.0 million revolving credit loan under the 2014 Credit Facility to finance the acquisition of MicroEdge.

The July 2015 Additional Revolving Credit Commitments have the same terms as the existing revolving credit commitments.

On October 2, 2015, we drew down a $186.0 million revolving credit loan under the 2014 Credit Facility to finance the acquisition of Smart Tuition.
