Senior Notes

In December 2017, the Company issued $750 million of 3.45% senior notes due December 15, 2027 (the "2027 Notes") and $500 million of 4.30% senior notes due December 15, 2047 (the "2047 Notes"). The 2027 Notes were sold at 99.76% of the principal amount and have an effective yield of 3.48%. The 2047 Notes were sold at 99.51% of the principal amount and have an effective yield of 4.33%. Interest on the 2027 Notes and the 2047 Notes is payable semi-annually in arrears, commencing on June 15, 2018. The 2027 and 2047 Notes rank pari passu to the Company's other senior notes, the Multi-Currency Revolving Credit Facility, the Revolving Credit Note, the Overdraft Facility, and the Term Loans.

The Company used the proceeds from the 2027 Notes and the 2047 Notes to finance the early retirement of the $400 million of 4.875% senior notes that were due in 2019, including the payment of a $22.3 million prepayment premium, and to finance the acquisition of H.D. Smith, which was completed on January 2, 2018 (see Note 2).

Multi-Currency Revolving Credit Facility

The Company has a $1.4 billion multi-currency senior unsecured revolving credit facility ("Multi-Currency Revolving Credit Facility"), which expires in November 2021, with a syndicate of lenders. Interest on borrowings under the Multi-Currency Revolving Credit Facility accrues at specified rates based on the Company’s debt rating and ranges from 70 basis points to 110 basis points over CDOR/LIBOR/EURIBOR/Bankers Acceptance Stamping Fee, as applicable (91 basis points over CDOR/LIBOR/EURIBOR/Bankers Acceptance Stamping Fee as of December 31, 2017) and from 0 basis points to 10 basis points over the alternate base rate and Canadian prime rate, as applicable. The Company pays facility fees to maintain the availability under the Multi-Currency Revolving Credit Facility at specified rates based on its debt rating, ranging from 5 basis points to 15 basis points, annually, of the total commitment (9 basis points as of December 31, 2017). The Company may choose to repay or reduce its commitments under the Multi-Currency Revolving Credit Facility at any time. The Multi-Currency Revolving Credit Facility contains covenants, including compliance with a financial leverage ratio test, as well as others that impose limitations on, among other things, indebtedness of subsidiaries and asset sales, with which the Company was compliant as of December 31, 2017.

Commercial Paper Program

The Company has a commercial paper program whereby it may from time to time issue short-term promissory notes in an aggregate amount of up to $1.4 billion at any one time. Amounts available under the program may be borrowed, repaid, and re-borrowed from time to time. The maturities on the notes will vary, but may not exceed 365 days from the date of issuance. The notes will bear interest, if interest bearing, or will be sold at a discount from their face amounts. The commercial paper program does not increase the Company’s borrowing capacity as it is fully backed by the Company’s Multi-Currency Revolving Credit Facility. There were no borrowings outstanding under the commercial paper program as of December 31, 2017.

Receivables Securitization Facility

The Company has a $1,450 million receivables securitization facility ("Receivables Securitization Facility"), which expires in November 2019. The Company has available to it an accordion feature whereby the commitment on the Receivables Securitization Facility may be increased by up to $250 million, subject to lender approval, for seasonal needs during the December and March quarters. Interest rates are based on prevailing market rates for short-term commercial paper or LIBOR, plus a program fee. The Company pays a customary unused fee at prevailing market rates, annually, to maintain the availability under the Receivables Securitization Facility. The Receivables Securitization Facility contains similar covenants to the Multi-Currency Revolving Credit Facility, with which the Company was compliant as of December 31, 2017.

Revolving Credit Note and Overdraft Facility

The Company has an uncommitted, unsecured line of credit available to it pursuant to a revolving credit note ("Revolving Credit Note"). The Revolving Credit Note provides the Company with the ability to request short-term unsecured revolving credit loans from time to time in a principal amount not to exceed $75 million. The Revolving Credit Note may be decreased or terminated by the bank or the Company at any time without prior notice. The Company also has a £30 million uncommitted U.K. overdraft facility ("Overdraft Facility"), which expires in February 2021, to fund short-term normal trading cycle fluctuations related to its MWI business.

Term Loans

In February 2015, the Company entered into a $1.0 billion variable-rate term loan ("February 2015 Term Loan"), which matures in 2020. Through December 31, 2017, the Company elected to make principal payments, prior to the scheduled repayment dates, of $775 million on the February 2015 Term Loan, and as a result, the Company’s next required principal payment is due upon maturity. The February 2015 Term Loan bears interest at a rate equal either to a base rate, plus a margin, or LIBOR, plus a margin. The margin is based on the public debt ratings of the Company and ranges from 75 basis points to 125 basis points over LIBOR (100 basis points as of December 31, 2017) and 0 basis points to 25 basis points over a base rate. The February 2015 Term Loan contains similar covenants to the Multi-Currency Revolving Credit Facility, with which the Company was compliant as of December 31, 2017.

In November 2015, the Company entered into a $1.0 billion variable-rate term loan ("November 2015 Term Loan"), which matures in 2020. Through December 31, 2017, the Company made a scheduled principal payment, as well as other principal payments prior to the scheduled repayment dates totaling $675 million on the November 2015 Term Loan, and as a result, the Company's next required principal payment is due upon maturity. The November 2015 Term Loan bears interest at a rate equal either to a base rate, plus a margin, or LIBOR, plus a margin. The margin is based on the public debt ratings of the Company and ranges from 75 basis points to 125 basis points over LIBOR (100 basis points as of December 31, 2017) and 0 basis points to 25 basis points over a base rate. The November 2015 Term Loan contains similar covenants to the Multi-Currency Revolving Credit Facility, with which the Company was compliant as of December 31, 2017.
