The effective interest rate on these notes is approximately 1.30%. These notes mature on November 25, 2025. These notes were partially repaid in the first quarter of 2021, as noted above. •€500.0 million aggregate principal amount of notes, bearing interest at a rate of 1.625% payable annually on November 25 of each year, beginning in 2020. The effective interest rate on these notes is approximately 1.74%. These notes mature on November 25, 2028. •$300.0 million aggregate principal amount of senior notes, bearing interest at a rate of 3.45% payable semi-annually on May 15 and November 15 of each year, beginning in 2020. The effective interest rate on these senior notes is approximately 3.58%. These senior notes mature on November 15, 2029. These notes were partially repaid in the first quarter of 2021, as noted above. The net proceeds from the issuance of the 2019 Notes were used to repay the $1.0 billion balance of the 2019 Credit Facility (see below for further details), a large portion of approximately $370 million of commercial paper notes, the remaining balance of $175.2 million of the senior notes issued on December 10, 2010 (“2010 Senior Notes”), and for general corporate purposes. The 2010 Senior Notes were originally due to mature on December 15, 2020 and bore interest at a rate of 4.50%. During the year ended December 31, 2019, we recorded a loss on early extinguishment of debt of $4.8 million in Interest and financing expenses, representing the tender premiums, fees, unamortized discounts and unamortized deferred financing costs from the redemption of the 2010 Senior Notes. 2014 Senior Notes We currently have the following senior notes outstanding, initially issued in the fourth quarter of 2014: •$425.0 million aggregate principal amount of senior notes, issued on November 24, 2014, bearing interest at a rate of 4.15% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 5.06%. These senior notes mature on December 1, 2024. •$350.0 million aggregate principal amount of senior notes, issued on November 24, 2014, bearing interest at a rate of 5.45% payable semi-annually on June 1 and December 1 of each year, beginning June 1, 2015. The effective interest rate on these senior notes is approximately 5.50%. These senior notes mature on December 1, 2044. On January 22, 2014, we entered into a pay fixed, receive variable rate forward starting interest rate swap, with a notional amount of $325.0 million, with J.P. Morgan Chase Bank, N.A., to be effective October 15, 2014. Our risk management objective and strategy for undertaking this hedge was to eliminate the variability in the interest rate and partial credit spread on the 20 future semi-annual coupon payments that we will pay in connection with our 4.15% senior notes. On October 15, 2014, the swap was settled, resulting in a payment to the counterparty of $33.4 million. This amount was recorded in Accumulated other comprehensive loss and is being amortized to interest expense over the life of the 4.15% senior notes. The amount to be reclassified to interest expense from Accumulated other comprehensive loss during the next twelve months is approximately $3.3 million. Prior to repayment in the first quarter of 2021, the carrying value of the 1.875% Euro-denominated senior notes was designated as an effective hedge of our net investment in certain foreign subsidiaries where the Euro serves as the functional currency, and gains or losses on the revaluation of these senior notes to our reporting currency were recorded in accumulated other comprehensive loss. Upon repayment of these notes, this net investment hedge was discontinued. The balance of foreign exchange revaluation gains and losses associated with this discontinued net investment hedge will remain within accumulated other comprehensive loss until the hedged net investment is sold or liquidated. Prior to the net investment hedge being discontinued, we recorded a gain of $5.1 million (net of income taxes) in 2021, and during the years ended December 31, 2020 and 2019, (losses) gains of ($34.2) million and $8.4 million (net of income taxes), respectively, were recorded in accumulated other comprehensive loss. Credit Agreements Our revolving, unsecured credit agreement dated as of June 21, 2018, as amended on August 14, 2019 and further amended on May 11, 2020 (the “2018 Credit Agreement”), currently provides for borrowings of up to $1.0 billion and matures on August 9, 2024. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on an average LIBOR for deposits in the relevant currency plus an applicable margin which ranges from 0.910% to 1.500%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services LLC (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”). The applicable margin on the facility was 1.125% as of December 31, 2021. There were no borrowings outstanding under the 2018 Credit Agreement as of December 31, 2021. On August 14, 2019, the Company entered into an unsecured credit facility (the “2019 Credit Facility”) with several banks and other financial institutions, which was amended and restated on December 15, 2020 and again on December 10, 2021. The lenders’ commitment to provide new loans under the amended 2019 Credit Facility permits up to four borrowings by the Company in an aggregate amount equal to $750 million. The 2019 Credit Facility terminates on December 9, 2022, with each such loan maturing 364 days after the funding of such loan. The Company can request that the maturity date of loans be extended for a period of up to four additional years, but any such extension is subject to the approval of the lenders. At the option of the Company the borrowings under the 2019 Credit Facility bear interest at variable rates based on an on either the base rate or LIBOR for deposits in U.S. dollars, in each case plus an applicable margin which ranges from 0.000% to 0.375% for base rate borrowings or 0.875% to 1.375% for LIBOR borrowings, depending on the Company’s credit rating from S&P, Moody’s and Fitch. The applicable margin on the credit facility was 1.125% as of December 31, 2021. There were no borrowings outstanding under the 2019 Credit Facility as of December 31, 2021. Borrowings under the under the 2019 Credit Facility and 2018 Credit Agreement (together the “Credit Agreements”) are conditioned upon satisfaction of certain conditions precedent, including the absence of defaults. The Company is subject to one financial covenant, as well as customary affirmative and negative covenants. The financial covenant requires that the Company’s consolidated net funded debt to consolidated EBITDA ratio (as such terms are defined in the Credit Agreements) be less than or equal to 4.00:1 for the fiscal quarter ending December 31, 2021 and 3.50:1 for fiscal quarters thereafter, subject to adjustments in accordance with the terms of the Credit Agreements relating to a consummation of an acquisition where the consideration includes cash proceeds from issuance of funded debt in excess of $500 million. The Credit Agreements also contain customary default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants and cross-defaults to other material indebtedness. The occurrence of an event of default under the Credit Agreements could result in all loans and other obligations becoming immediately due and payable and each such Credit Agreement being terminated. Certain representations, warranties and covenants under the 2018 Credit Agreement were conformed to those under the 2019 Credit Facility following the amendments to those agreements. Commercial Paper Notes On May 29, 2013, we entered into agreements to initiate a commercial paper program on a private placement basis under which we may issue unsecured commercial paper notes (the “Commercial Paper Notes”) from time-to-time up to a maximum aggregate principal amount outstanding at any time of $750.0 million. The proceeds from the issuance of the Commercial Paper Notes are expected to be used for general corporate purposes, including the repayment of other debt of the Company. The Credit Agreements are available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the Credit Agreements and the Commercial Paper Notes will not exceed the $1.75 billion current maximum amount available under the Credit Agreements. The Commercial Paper Notes will be sold at a discount from par, or alternatively, will be sold at par and bear interest at rates that will vary based upon market conditions at the time of issuance. The maturities of the Commercial Paper Notes will vary but may not exceed 397 days from the date of issue. The definitive documents relating to the commercial paper program contain customary representations, warranties, default and indemnification provisions. At December 31, 2021, we had $388.5 million of Commercial Paper Notes outstanding bearing a weighted-average interest rate of approximately 0.46% and a weighted-average maturity of 20 days. Other We have additional uncommitted credit lines with various U.S. and foreign financial institutions that provide for borrowings of up to approximately $239.2 million at December 31, 2021. Outstanding borrowings under these agreements were $5.2 million and $7.7 million at December 31, 2021 and 2020, respectively. The average interest rate on borrowings under these agreements during 2021, 2020 and 2019 was approximately 0.36%. At December 31, 2021 and 2020, we had the ability and intent to refinance our borrowings under our other existing credit lines with borrowings under the Credit Agreements. Therefore, the amounts outstanding under those credit lines, if any, are classified as long-term debt at December 31, 2021 and 2020. At December 31, 2021, we had the ability to borrow $1.36 billion under our commercial paper program and the Credit Agreements. We believe that as of December 31, 2021, we were, and currently are, in compliance with all of our debt covenants.
