Term Loan A and Revolver

As of December 31, 2013, our credit facility consists of a $600 million term loan facility (Term Loan A) and a $100 million committed revolving credit facility (the Revolver). Borrowings under the credit facility are secured by a first charge over substantially all of our assets. We entered into this credit facility and borrowed the full amount under Term Loan A on November 9, 2011.

Term Loan A has a five year term and repayments made under Term Loan A are 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. For the three and six months ended December 31, 2013, interest on Term Loan A was at a floating rate of LIBOR plus 2.25%. For the three and six months ended December 31, 2012, interest was at a floating rate of LIBOR plus 2.5%.

For the three and six months ended December 31, 2013, we recorded interest expense of $3.4 million and $6.9 million, respectively, relating to Term Loan A (three and six months ended December 31, 2012—$4.1 million and $8.2 million, respectively).

The Revolver has a five year term with no fixed repayment date prior to the end of the term. As of December 31, 2013, we have not drawn any amounts on the Revolver.

Mortgage

We currently have an "open" mortgage with a bank where we can pay all or a portion of the mortgage on or before August 1, 2014. 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 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, 2013, the carrying value of the mortgage was approximately $10.0 million (June 30, 2013—$10.5 million).

As of December 31, 2013, the carrying value of the Waterloo building that secures the mortgage was $15.9 million (June 30, 2013—$16.1 million).

For the three and six months ended December 31, 2013, we recorded interest expense of $0.1 million and $0.2 million, respectively, relating to the mortgage (three and six months ended December 31, 2012—$0.1 million and $0.2 million).
