July 2015 Refinancing

On July 31, 2015, we entered into a second amended and restated term loan agreement (the "2015 Term Loan Agreement") and a second amended and restated credit agreement (the "2015 Revolving Credit Facility Agreement" and collectively, the "2015 Credit Facility Agreements") to provide for a $1.75 billion term loan (the "Term A Loan") and a $1.25 billion revolving credit facility (the "Revolving Credit Facility"), each with a syndicate of financial institutions. We used the proceeds of approximately $2.0 billion to repay the then-outstanding balances on our previously existing term loan and revolving credit facility.

February 2016 Refinancing

In connection with the Merger Agreement on February 26, 2016, we entered into an amendment to the 2015 Credit Facility Agreements (as amended, the "2016 Credit Facility Agreement") to, among other things, (i) accelerate our repayment schedule for the Term A Loan, effective as of February 26, 2016, and (ii) provide security for the Term A Loan and the Revolving Credit Facility and modify the applicable financial covenants and interest rate margins. In addition, the 2016 Credit Facility Agreement provided for a new $735 million delayed draw term loan facility (the "Delayed Draw Facility").

We also entered into a new $1.045 billion term B loan ("Heartland Incremental Term B Loan Lender Rejoinder Agreement" or "Term B Loans"). The Delayed Draw Facility and Term B Loans were issued on April 22, 2016 in connection with our merger with Heartland, resulting in total financing of approximately $4.78 billion as contemplated by the debt commitment letter. The incremental proceeds from the new loans were used, among other things, to repay certain portions of Heartland’s existing indebtedness and to finance, in part, the cash consideration and the merger-related costs. Substantially all of the assets of our domestic subsidiaries are pledged as collateral under the 2016 Credit Facility Agreement.

The 2016 Credit Facility Agreement provides for an interest rate, at our election, of either LIBOR or a base rate, in each case plus a leverage-based margin. As of May 31, 2016, the interest rates on the Term A Loan, the Term B Loans and the Delayed Draw Facility were 2.95%, 3.94% and 2.91%, respectively.

Pursuant to the 2016 Credit Facility Agreement, the Term A Loan must be repaid in equal quarterly installments of $43.8 million commencing in November 2016 and ending in May 2020, with the remaining principal balance due upon maturity in July 2020. The Delayed Draw Facility must be repaid in equal quarterly installments of $1.7 million commencing in August 2016, increasing to quarterly installments of $8.6 million in August 2018 and ending in May 2020, with the remaining principal balance due upon maturity in July 2020. The Term B Loans must be repaid in equal quarterly installments of $2.6 million commencing in September 2016 and ending in March 2023, with the remaining principal balance due upon maturity in April 2023.

As of May 31, 2016, the outstanding balance on the Revolving Credit Facility was $1,037.0 million. The 2016 Credit Facility Agreement allows us to issue standby letters of credit of up to $100 million in the aggregate under the Revolving Credit Facility. Outstanding letters of credit under the Revolving Credit Facility reduce the amount of borrowings available to us. Borrowings available to us under the Revolving Credit Facility are further limited by the covenants described below under "Compliance with Covenants." At May 31, 2016 and 2015, we had outstanding issued standby letters of credit under the Revolving Credit Facility of $8.5 million and $7.6 million, respectively. The total available commitments under the Revolving Credit Facility at May 31, 2016 and 2015 were $204.5 million and $484.3 million, respectively. As of May 31, 2016, the interest rate on the Revolving Credit Facility was 2.91%. In addition, we are required to pay a quarterly commitment fee on the unused portion of the Revolving Credit Facility. The Revolving Credit Facility expires in July 2020.

The 2015 Credit Facility, the Delayed Draw Facility, 2016 Credit Facility and the Term B Loans were combined in evaluating the accounting treatment for fees and expenses incurred. We incurred fees and expenses associated with the 2015 Credit Facility, Delayed Draw Facility, 2016 Credit Facility Agreement and the Term B Loans of approximately $63.4 million. The portion of the debt issuance costs related to the 2015 and 2016 Revolving Credit Facility Agreements are included in other noncurrent assets, and the portion of the debt issuance costs related to the 2015 and 2016 Term Loan Agreement are reported as a reduction to the carrying amount of the debt at May 31, 2016. Debt issuance costs are amortized as an adjustment to interest expense over the terms of the respective facilities.

Settlement Lines of Credit

We have lines of credit with banks in the United States and Canada as well as several countries in Europe and in the Asia-Pacific region where we do business. The lines of credit, which are restricted for use in funding settlement, generally have variable interest rates and are subject to annual review. The credit facilities are generally denominated in local currency but may, in some cases, facilitate borrowings in multiple currencies. For certain of our lines of credit, the available credit is increased by the amount of cash we have on deposit in specific accounts with the lender. Accordingly, the amount of the outstanding line of credit may exceed the stated credit limit. As of May 31, 2016 a total of $42.9 million of cash on deposit was used to determine the available credit.

As of May 31, 2016 and 2015, respectively, we had $378.4 million and $592.6 million outstanding under these lines of credit with additional capacity as of May 31, 2016 of $733.2 million to fund settlement. The weighted-average interest rate on these borrowings was 1.8% and 1.5%, at May 31, 2016 and 2015, respectively.

During the year ended May 31, 2016, the maximum and average outstanding balances under these lines of credit were $659.1 million and $302.6 million, respectively.

Compliance with Covenants

The 2016 Credit Facility Agreement contains customary affirmative and restrictive covenants, including, among others, financial covenants based on our leverage and fixed charge coverage ratios. Financial covenants require a leverage ratio no greater than (i) 5.00 to 1.00 as of the end of any fiscal quarter ending during the period from April 22, 2016 through August 31, 2016, (ii) 4.75 to 1.00 as of the end of any fiscal quarter ending during the period from September 1, 2016 through February 28, 2017, (iii) 4.50 to 1.00 as of the end of any fiscal quarter ending during the period from March 1, 2017 through August 31, 2017, (iv) 4.25 to 1.00as of the end of any fiscal quarter ending during the period from September 1, 2017 through February 28, 2018 and (v) 4.00 to 1.00 as of the end of any fiscal quarter ending thereafter. The fixed charge coverage ratio is required to be no less than 2.25 to 1.00. The 2016 Credit Facility Agreement and settlement lines of credit also include various other covenants that are customary in such borrowings. The 2016 Credit Facility Agreement includes covenants, subject in each case to exceptions and qualifications, that may restrict certain payments, including, in certain circumstances, the payment of cash dividends in excess of our current rate of $0.01 per share per quarter.

The 2016 Credit Facility Agreement also includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations to be immediately due and payable. We were in compliance with all applicable covenants as of and for the year ended May 31, 2016.

Interest Rate Swap Agreements

We have interest rate swap agreements with financial institutions to hedge changes in cash flows attributable to interest rate risk on a portion of our variable-rate debt instruments. A $500 million notional interest rate swap agreement, which became effective on October 31, 2014, effectively converted $500 million of our variable-rate debt to a fixed rate of 1.52% plus a leverage-based margin and will mature on February 28, 2019. A $250 million notional interest rate swap, which became effective on August 28, 2015, effectively converted $250 million of our variable-rate debt to a fixed rate of 1.34% plus a leverage-based margin and will mature on July 31, 2020.

Net amounts to be received or paid under the swap agreements are reflected as adjustments to interest expense. Since we have designated the interest rate swap agreements as portfolio cash flow hedges, unrealized gains or losses resulting from adjusting the swaps to fair value are recorded as components of other comprehensive income, except for any ineffective portion of the change in fair value, which would be immediately recorded in interest expense. During the years ended May 31, 2016 and 2015, there was no ineffectiveness. The fair values of the interest rate swaps were determined based on the present value of the estimated future net cash flows using implied rates in the applicable yield curve as of the valuation date. These derivative instruments were classified within Level 2 of the valuation hierarchy.

The table below presents the fair values of our derivative financial instruments designated as cash flow hedges included within accounts payable and accrued liabilities in the consolidated balance sheets (in thousands):



	2016		2015
Interest rate swaps ($750 million notional)	$	10,775	$	6,157

The table below presents the effects of our interest rate swaps on the consolidated statements of income and comprehensive income for the years ended May 31, 2016 and 2015 (in thousands):



	2016		2015
Amount of loss recognized in other comprehensive loss	$	12,859	$	10,116
Amount of loss recognized in interest expense	$	8,240	$	3,958

At May 31, 2016, the amount in accumulated other comprehensive loss related to our interest rate swaps that is expected to be reclassified into interest expense during the next 12 months was approximately $5.9 million.

Interest Expense

Interest expense was $67.9 million, $39.9 million and $37.5 million for the years ended May 31, 2016, 2015 and 2014, respectively.
