Term Loan A and Revolver

As of December 31, 2014, 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), together defined as the "2011 Credit Agreement". We entered into a second amendment to the 2011 Credit Agreement (the Second Amendment) on December 22, 2014 whereby the 2011 Credit Agreement was amended to, among other things, (i) increase the total commitments under the Revolver to $300 million from $100 million, (ii) reduce the interest rate margin for the Revolver, (iii) extend the maturity date of the Revolver to December 22, 2019, (iv) make certain technical and other amendments to the 2011 Credit Agreement and (v) provide for the further amendment and restatement of the 2011 Credit Agreement in the event of certain circumstances and the satisfaction of certain conditions precedent (which were satisfied upon the repayment of Term Loan A).

Borrowings under Term Loan A and 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). We entered into this credit facility and borrowed the full amount under Term Loan A on November 9, 2011.

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. As of December 31, 2014, this fixed amount was 2.5%.

For the three and six months ended December 31, 2014, we recorded interest expense of $3.4 million and $7.1 million, respectively, relating to Term Loan A (three and six months ended December 31, 2013—$3.4 million and $6.9 million, respectively).

The Revolver will mature on December 22, 2019 with no fixed repayment date prior to the end of the term. As of December 31, 2014, we have not drawn any amounts on the Revolver.

On January 15, 2015, we used a portion of the net proceeds of the offering of our 5.625% Senior Notes due 2023 (the notes), as described below, to repay in full the outstanding Term Loan A.

For further details on recent developments related to the 2011 Credit Agreement, see note 22 "Subsequent Events - Senior Unsecured Fixed Rate Notes and Repayment of Term Loan A" and "Second Amendment to 2011 Credit Agreement".

Term Loan B

In connection with the acquisition of GXS Group, Inc. (GXS), on January 16, 2014, we entered into a second 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 Term Loan A (prior to the repayment of Term Loan A) and 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 three and six months ended December 31, 2014, we recorded interest expense of $6.6 million and $13.2 million, respectively, relating to Term Loan B.

Mortgage

We currently have an "open" mortgage with a Canadian bank where we can pay all or a portion of the mortgage on or before August 1, 2015. The original principal amount of the mortgage was Canadian $15.0 million and interest accrues monthly at a variable rate of Canadian prime plus 0.50%. Principal and interest are payable in monthly installments of approximately Canadian $0.1 million with a final lump sum principal payment due on maturity. The mortgage is secured by a lien on our headquarters in Waterloo, Ontario, Canada. We first entered into this mortgage in December 2005.

As of December 31, 2014, the carrying value of the mortgage was approximately $8.5 million (June 30, 2014—$9.6 million).

As of December 31, 2014, the carrying value of the Waterloo building that secures the mortgage was $15.5 million (June 30, 2014—$15.6 million).

For the three and six months ended December 31, 2014, we recorded interest expense of approximately $0.1 million and $0.2 million, respectively, relating to the mortgage (three and six months ended December 31, 2013—$0.1 million and $0.2 million, respectively).
