The 2024 Notes were originally due to mature on December 15, 2024 and bore interest at a rate of 4.15%. During the year ended December 31, 2022, the Company recorded a loss on early extinguishment of debt of $19.2 million in Interest and financing expenses, representing the tender premiums, fees, unamortized discounts and unamortized deferred financing costs from the redemption of the 2024 Notes.

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.

We currently have $350.0 million aggregate principal amount of senior notes outstanding, which were 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.

In the first quarter of 2021, the Company made certain debt principal payments using proceeds from the February 2021 underwritten public offering of common stock. As a result, included in Interest and financing expenses for the year ended December 31, 2021 is a loss on early extinguishment of debt of $29.0 million representing the tender premiums, fees, unamortized discounts and unamortized deferred financing costs from the redemption of this debt.

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 were to be paid in connection with the 2024 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 was to be amortized to interest expense over the life of the 2024 Notes. As noted above, the 2024 Notes were repaid in the second quarter of 2022, and as a result, the unamortized balance of this interest rate swap was reclassified to interest expense during the same period as part of the early extinguishment of debt..

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, gains (losses) of $5.1 million and ($34.2) million (net of income taxes), during the years ended December 31, 2021 and 2020, respectively, were recorded in Accumulated other comprehensive loss.

On October 28, 2022, we amended our revolving, unsecured credit agreement (the “2018 Credit Agreement”), which provides for borrowings of up to $1.5 billion and matures on October 28, 2027. This credit agreement was originally dated as of June 21, 2018, and was previously amended on August 14, 2019, May 11, 2020 and December 10, 2021. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on a benchmark rate depending on the currency in which the loans are denominated, plus an applicable margin which ranges from 0.910% to 1.375%, 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”). With respect to loans denominated in U.S. dollars, interest is calculated using the term Secured Overnight Financing Rate (“SOFR”) plus a term SOFR adjustment of 0.10%, plus the applicable margin. The applicable margin on the facility was 1.125% as of December 31, 2022. There were no borrowings outstanding under the 2018 Credit Agreement as of December 31, 2022.

On August 14, 2019, the Company entered into a $1.2 billion unsecured 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 “2019 Credit Facility”). On October 24, 2022, the 2019 Credit Facility was terminated, with the outstanding balance of $250 million repaid using cash on hand.

Borrowings under the 2018 Credit Agreement 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 2018 Credit Agreement) be less than or equal to 3.50:1 for all fiscal quarters, subject to adjustments in accordance with the terms of the 2018 Credit Agreement relating to a consummation of an acquisition where the consideration includes cash proceeds from issuance of funded debt in excess of $500 million. The 2018 Credit Agreement also contains 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 2018 Credit Agreement could result in all loans and other obligations becoming immediately due and payable and the 2018 Credit Agreement being terminated.

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 2018 Credit Agreement is available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the 2018 Credit Agreement and the Commercial Paper Notes will not exceed the $1.5 billion current maximum amount available under the 2018 Credit Agreement. 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. There were no Commercial Paper Notes outstanding at December 31, 2022.

We have additional uncommitted credit lines with various U.S. and foreign financial institutions that provide for borrowings of up to approximately $274.3 million at December 31, 2022. Outstanding borrowings under these agreements were $3.0 million and $5.2 million at December 31, 2022 and 2021, respectively. The average interest rate on borrowings under these agreements during 2022, 2021 and 2020 was approximately 0.36%.
