Senior Credit Facility

On December 12, 2017, the Company entered into a credit agreement with a group of lenders for a $3.0 billion credit facility ("Senior Credit Facility"), comprised of a $2.0 billion senior unsecured multicurrency revolving credit facility ("Revolving Facility") and an approximately $1.0 billion senior unsecured multicurrency term loan facility ("Term Loan Facility"). The Senior Credit Facility contains customary covenants, including financial covenants which require the Company to maintain certain financial coverage and leverage ratios, as well as customary events of default. The Senior Credit Facility has a five year term, maturing on December 12, 2022.

Revolving Facility

The Revolving Facility allows the Company to borrow, repay and reborrow over its term. The Revolving Facility provides a sublimit for the issuance of letters of credit of up to $250.0 million at any one time. Borrowings under the Revolving Facility bear interest at a rate based on a benchmark rate defined in the credit agreement plus a margin that can vary from 0.85% to 1.40% or, at the Company's option, the base rate, which is defined as the highest of (a) the Federal Funds Rate plus 0.5%, (b) the Bank of America prime rate and (c) one-month LIBOR plus 1% plus a margin that can vary from 0.0% to 0.4%. The Company is required to pay a quarterly letter of credit fee on the face amount of each letter of credit, which fee is based on the same margin that applies from time to time to borrowings under the Revolving Facility. The Company is also required to pay a quarterly facility fee ranging from 0.15% to 0.30% per annum based on the total Revolving Facility amount.

In March 2020, the Company borrowed a total of $250.0 million under the Revolving Facility, which was fully repaid in May 2020. As of December 31, 2020, there was no outstanding balance under the Revolving Facility. As of December 31, 2020, the Company had 37 irrevocable letters of credit totaling $74.6 million issued and outstanding under the Revolving Facility and the amount available to the Company to borrow under the Revolving Facility was approximately $1.9 billion as of December 31, 2020.

Term Loan Facility

On December 12, 2017, the Company borrowed £500.0 million and SEK 2.8 billion under the Term Loan Facility, or approximately $997.1 million at the exchange rates in effect on that date. The Company is required to repay the Term Loan Facility at the rate of 5% of the original principal amount per annum with the remaining balance to be repaid in full at the maturity of the Senior Credit Facility. The Term Loan Facility bears interest at a rate based on LIBOR plus a margin that can vary from 1.00% to 1.70%. As of December 31, 2020, the Company had £431.3 million and SEK2,415.0 million, or approximately $883.6 million in U.S. dollars at the exchange rates in effect as of December 31, 2020, outstanding under the Term Loan Facility with a weighted average effective interest rate of 1.85% per annum. Debt issuance costs related to the Term Loan Facility, net of amortization, were $1.2 million as of December 31, 2020.

On July 26, 2018, the Company entered into an amendment to its Senior Credit Facility. The amendment provided for a senior unsecured term loan in an aggregate principal amount of ¥47.5 billion (the "JPY Term Loan").

On July 31, 2018, the Company drew down the full ¥47.5 billion of the JPY Term Loan, or approximately $424.7 million at the exchange rate effective on July 31, 2018, and prepaid the remaining principal of its existing Japanese Yen Term Loan of ¥43.8 billion or approximately $391.3 million. The Company is required to repay the JPY Term Loan at the rate of 5% of the original principal amount per annum with the remaining balance to be repaid in full at the maturity of the Senior Credit Facility. The JPY Term Loan bears interest at a rate based on LIBOR plus a margin that can vary from 1.00% to 1.70% and contains customary covenants consistent with the Senior Credit Facility. As of December 31, 2020, total outstanding borrowings under the JPY Term Loan were ¥42.2 billion, or approximately $408.5 million at the exchange rate effective on that date, with an effective interest rate of 1.74%. Debt issuance costs, net of amortization, related to the JPY Term Loan were $2.1 million as of December 31, 2020.

364-Day Facilities

On April 15, 2020, the Company entered into a credit agreement which provided for senior unsecured 364-day term loan facilities in an aggregate principal amount of $750.0 million, comprised of $500.0 million available to be borrowed on the closing date (the "Closing Date Facility") and $250.0 million available to be borrowed on or prior to July 14, 2020 (the "Delayed Draw Facility" and together with the Closing Date Facility, the "364-Day Facilities"). On April 15, 2020, the Company borrowed $391.0 million, as well as €100.0 million or $109.8 million at the exchange rate in effect on that date, under the Closing Date Facility. During the quarter ended June 30, 2020, the Company repaid all amounts outstanding under the Closing Date Facility and terminated the 364-Day Facilities. The loss on debt extinguishment incurred in connection with the redemption and termination was not significant.

All of the Company's senior notes are unsecured and rank equal in right of payment to the Company's existing or future senior indebtedness and senior in right of payment to the Company's existing and future subordinated indebtedness. Interest on the senior notes is paid semi-annually in arrears. The senior notes are effectively subordinated to all of the existing and future secured debt, including debt outstanding under any bank facility or secured by any mortgage, to the extent of the assets securing such debt. They are also structurally subordinated to any existing and future indebtedness and other liabilities (including trade payables) of any of the Company's subsidiaries.

Each series of senior notes is governed by an indenture and a supplemental indenture between the Company and U.S. Bank National Association, as trustee. These supplemental indentures contain covenants that limit the Company's ability and the ability of its subsidiaries to, among other things:

•purchase, redeem or retire capital stock or subordinated debt(1);

•incur liens;

•enter into sale-leaseback transactions (1);

•make investments(1); and

•merge or consolidate with any other person.

(1) The supplemental indentures for the 2.875% Euro Senior Notes due 2026 and the 5.375% due 2027 contain these covenants.

As of December 31, 2020, the Company was in compliance with all covenants. Subject to compliance with the limitations described above, the Company may issue an unlimited principal amount of additional notes at later dates under the same indenture as the senior notes.

The Company is not required to make any mandatory redemption with respect to the senior notes; however, upon the event of a change in control, the Company may be required to offer to purchase the senior notes.
