Senior Notes
The Senior Notes listed above are senior unsecured obligations of the Company and interest is payable semi-annually. The Company may at any time prepay the Senior Notes, in whole or in part, at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interests, and in some instances a “make whole” prepayment premium. The Euro Senior Notes, if prepaid, may also include a swap related currency loss. The Senior Notes each contain customary affirmative and negative covenants including, among others, limitations on the Company and its subsidiaries with respect to incurrence of liens and priority indebtedness, disposition of assets, mergers, and transactions with affiliates. In December 2021, the Company amended all of its U.S. Senior Note agreements to conform to the financial
covenants in the underlying agreements. The amended agreements require the Company to maintain a consolidated interest coverage ratio of not less than 3.0 to 1.0 and a net consolidated leverage ratio of not more than 3.5 to 1.0. The Senior Notes also contain customary events of default with customary grace periods, as applicable. The Company was in compliance with its covenants at December 31, 2021.
Total issuance costs of approximately $4.1 million have been incurred by the Company related to the Senior Notes mentioned above and are being amortized to interest expense over the various terms.
In December 2021, the Company entered into an agreement to issue and sell $300 million 15-year Senior Notes in a private placement. The Company will issue $150 million with a fixed interest rate of 2.81% (2.81% Senior Notes) in March 2022 and will issue $150 million with a fixed interest rate of 2.91% (2.91% Senior Notes) in September 2022. The Senior Notes will be senior unsecured obligations of the Company. The 2.81% Senior Notes mature in March 2037 and the 2.91% Senior Notes mature in September 2037. Interest on the 2.81% and 2.91% Senior Notes will be payable semi-annually in March and September each year. Interest on the 2.81% Senior Notes will begin in September 2022 and interest on the 2.91% will begin in March 2023. The terms of the Senior Notes are consistent with the previous Senior Notes as described above. The Company will use the proceeds from the sale of the notes to refinance existing indebtedness and for other general corporate purposes.
In May 2021, the Company entered into an agreement to issue and sell $125 million 12-year Senior Notes with a fixed interest rate of 2.83%. The Senior Notes were issued in July 2021 and will mature in July 2033. The terms of the Senior Notes are consistent with the previous Senior Notes as described above. The Company used the proceeds from the sale of the notes to refinance existing indebtedness and for other general corporate purposes.
In December 2020, the Company entered into an agreement to issue and sell EUR 125.0 million 15-year 1.06% Euro Senior Notes (1.06% Euro Senior Notes). The terms of the Euro Senior Notes are consistent with the previous Euro Senior Notes as described above. The Company also entered into a forward contract to receive $152.1 million at the time of issuing the 1.06% Euro Senior Notes in March 2021. The proceeds will be used to repay outstanding amounts on the Company’s credit facility and fund operational expenses. The 1.06% Euro Senior Notes will be designated as a hedge of a portion of the Company’s net investment in a euro-denominated foreign subsidiary to reduce foreign currency risk associated with this net investment.
The Company has designated the EUR 125 million 1.47% Euro Senior Notes, the EUR 135 million 1.30% Euro Senior Notes, and the EUR 125 million 1.06% Euro Senior Notes as a hedge of a portion of its net investment in a euro-denominated foreign subsidiary to reduce foreign currency risk associated with this net investment. Changes in the carrying value of this debt resulting from fluctuations in the euro to U.S. dollar exchange rate are recorded as foreign currency translation adjustments within other comprehensive income (loss). The Company recorded in other comprehensive income (loss) related to this net investment hedge an unrealized gain of $34.3 million, an unrealized loss of $27.3 million, and an unrealized gain of $1.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. The Company has a gain of $5.5 million recorded in accumulated other comprehensive income (loss) as of December 31, 2021.
Credit Agreement
On June 25, 2021, the Company entered into a $1.25 billion Credit Agreement (the Credit Agreement), which amended its $1.1 billion Amended and Restated Credit Agreement (the Prior Credit
Agreement). As of December 31, 2021, the Company had $649.0 million of additional borrowings available under its Credit Agreement.
The Credit Agreement is provided by a group of financial institutions (similar to the Company's Prior Credit Agreement) and has a maturity date of June 25, 2026. It is a revolving credit facility and is not subject to any scheduled principal payments prior to maturity. The obligations under the Credit Agreement are unsecured.
Borrowings under the Credit Agreement bear interest at current market rates plus a margin based on the Company’s consolidated leverage ratio. The Company must also pay facility fees that are tied to its leverage ratio. The Credit Agreement contains covenants that are similar to those contained in the Prior Credit Agreement, with which the Company was in compliance as of December 31, 2021. The Company is required to maintain (i) a ratio of net funded indebtedness to EBITDA of 3.5 to 1.0 or less except in certain circumstances and (ii) an interest coverage ratio of 3.0 to 1.0 or greater. The Credit Agreement also places certain limitations on the Company, including limiting the ability to incur liens or indebtedness at a subsidiary level. In addition, the Credit Agreement has several events of default, with customary grace periods as applicable. The Company incurred approximately $0.2 million of debt extinguishment costs during 2021 related to the Prior Credit Agreement. The Company capitalized $2.0 million in financing fees during 2021 associated with the Credit Agreement, which will be amortized to interest expense through 2026.
Other Local Arrangements
In April 2018, two of the Company’s non-U.S. pension plans issued loans totaling $39.6 million (Swiss franc 38 million) to a wholly owned subsidiary of the Company. The loans have the same terms and conditions, which include an interest rate of Swiss franc LIBOR plus 87.5 basis points. The loans were renewed for one year in April 2021.
