Senior Unsecured Fixed Rate Notes

On January 15, 2015, we issued $800 million in aggregate principal amount of our 5.625% Senior Notes due 2023 (Senior Notes) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (Securities Act), and to certain persons in offshore transactions pursuant to Regulation S under the Securities Act. Senior Notes bear interest at a rate of 5.625% per annum, payable semi-annually in arrears on January 15 and July 15, commencing on July 15, 2015. Senior Notes will mature on January 15, 2023, unless earlier redeemed, in accordance with their terms, or repurchased.

For the year ended June 30, 2015, we recorded interest expense of $20.6 million relating to Senior Notes.

Term Loan A and Revolver

Prior to January 15, 2015, one of our credit facilities consisted of a $600 million term loan facility (Term Loan A) and a $300 million committed revolving credit facility (the Revolver and, together with Term Loan A, defined as the 2011 Credit Agreement).

On January 15, 2015, concurrently with the closing of the offering of Senior Notes, we used a portion of the net proceeds from the offering of Senior Notes to repay in full, the outstanding balance of Term Loan A.

Term Loan A had a five year term and repayments made under Term Loan A were equal to 1.25% of the original principal amount at each quarter for the first 2 years, approximately 1.88% for years 3 and 4 and 2.5% for year 5. Term Loan A bore interest at a floating rate of LIBOR plus a fixed amount, depending on our consolidated leverage ratio. Prior to the repayment of Term Loan A, the fixed amount was 2.5%.

For the year ended June 30, 2015, we recorded interest expense of $7.7 million relating to Term Loan A (June 30, 2014—$13.7 million, June 30, 2013—$15.5 million).

On January 15, 2015, concurrently with the closing of the offering of the Senior Notes and effective upon the repayment in full of Term Loan A with a portion of the net proceeds of the offering, the 2011 Credit Agreement was amended and restated as described in the second amendment to the 2011 Credit Agreement to, among other things, remove the provisions related to Term Loan A and modify certain provisions related to the incurrence of debt and liens and the making of acquisitions, investments and restricted payments, replace the covenants to maintain a “consolidated leverage” ratio of no more than 3:1 and a “consolidated interest coverage” ratio of 3:1 or more with a covenant to maintain a “consolidated net leverage” ratio of no more than 4:1, and make other changes, in each case, generally to conform with Term Loan B, as further described below.

Borrowings under the Revolver are secured by a first charge over substantially all of our assets, and as of January 16, 2014, on a pari passu basis with Term Loan B (as defined below). As part of the second amendment to the 2011 Credit Agreement, the commitments available under the Revolver was increased to $300 million from $100 million. The Revolver will mature on December 22, 2019 with no fixed repayment date prior to the end of the term. As of June 30, 2015, we have not drawn any amounts on the Revolver.

Term Loan B

In connection with the acquisition of GXS Group, Inc. (GXS), on January 16, 2014, we entered into a credit facility, which provides for a $800 million term loan facility (Term Loan B).

Borrowings under Term Loan B are secured by a first charge over substantially all of our assets on a pari passu basis with the Revolver. We entered into Term Loan B and borrowed the full amount on January 16, 2014.

Term Loan B has a seven year term and repayments made under Term Loan B are equal to 0.25% of the original principal amount in equal quarterly installments for the life of Term Loan B, with the remainder due at maturity. Borrowings under Term Loan B currently bear a floating rate of interest at a rate per annum equal to 2.5% plus the higher of LIBOR or 0.75%.

For the year ended June 30, 2015, we recorded interest expense of $26.1 million relating to Term Loan B (June 30, 2014—$11.9 million).

Mortgage

During the fourth quarter of Fiscal 2015, we repaid in full the outstanding balance of our mortgage of $7.8 million. The original principal amount of the mortgage was Canadian $15.0 million and interest accrued monthly at a variable rate of Canadian prime plus 0.50%.

For the year ended June 30, 2015, we recorded interest expense of approximately $0.3 million relating to the mortgage (June 30, 2014—$0.3 million, June 30, 2013—$0.4 million).
