(1)	The fair value of each series of the Company’s Senior Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 5).

Revolving Credit Facility

On November 30, 2021, the Company amended and restated its $2,500.0 unsecured revolving credit facility (the “Revolving Credit Facility”). As a result, the Revolving Credit Facility no longer references LIBOR for interest rate determinations. The Revolving Credit Facility maintains the lenders’ aggregate commitments under the facility at $2,500.0. The Revolving Credit Facility matures in November 2026 and gives the Company the ability to borrow, in various currencies, at a spread that varies based on the Company’s debt rating over certain currency-specific benchmark rates, which benchmark rates in the case of U.S. dollar borrowings are either the base rate or the adjusted term SOFR. The Company may utilize the Revolving Credit Facility for general corporate purposes.

Due to the significant volatility in the credit and capital markets resulting from the outbreak of the COVID-19 pandemic, the Company borrowed approximately $1,255.6 under the Revolving Credit Facility in the first quarter of 2020, at a weighted average interest rate of 1.82%. The outstanding borrowings as of March 31, 2020 included €200.0 ($217.4 at date of issuance) of euro-denominated borrowings, with the remainder of the outstanding borrowings denominated in U.S. dollars. The borrowings under the Revolving Credit Facility during the first quarter of 2020 were used in part to repay outstanding balances under the U.S. Commercial Paper Program and the Euro Commercial Paper Program (each as defined below). During the second quarter of 2020, the Company repaid all of the outstanding borrowings under the Revolving Credit Facility using cash and cash equivalents on hand as well as the net proceeds from the 2026 Euro Notes (defined below). At December 31, 2021 and 2020, there were no outstanding borrowings under the Revolving Credit Facility. The carrying value of any borrowings under the Revolving Credit Facility would approximate their fair value due primarily to their market interest rates and would be classified as Level 2 in the fair value hierarchy (Note 5). Any outstanding borrowings under the Revolving Credit Facility are classified as long-term

debt in the accompanying Consolidated Balance Sheets. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants.

Commercial Paper Programs

The Company has a commercial paper program (the “U.S. Commercial Paper Program”) pursuant to which the Company may issue short-term unsecured commercial paper notes (the “USCP Notes” or “U.S. Commercial Paper”) in one or more private placements in the United States. The maturities of the USCP Notes vary, but may not exceed 397 days from the date of issue. The USCP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom, and bear varying interest rates on a fixed or floating basis. The maximum aggregate principal amount outstanding of USCP Notes at any time is $2,500.0. On April 7, 2021, a combination of borrowings under the U.S. Commercial Paper Program and cash on hand were used to fund the acquisition of MTS Systems Corporation (“MTS”). In 2021, the Company also used borrowings under the U.S. Commercial Paper Program to (i) redeem, in the third quarter of 2021, its unsecured 3.125% Senior Notes (the “2021 Senior Notes”) due September 15, 2021, of which $227.7 aggregate principal amount was outstanding and (ii) redeem, in the fourth quarter of 2021, its unsecured 4.00% Senior Notes (the “2022 Senior Notes”) due February 1, 2022, of which $295.0 aggregate principal amount was outstanding. At December 31, 2021, the amount of USCP Notes outstanding was $795.2, with a weighted average interest rate of 0.29%. At December 31, 2020, there were no USCP Notes outstanding under the U.S. Commercial Paper Program.

In July 2018, the Company and one of its wholly owned European subsidiaries (the “Euro Issuer”) entered into a commercial paper program (the “Euro Commercial Paper Program” and, together with the U.S. Commercial Paper Program, the “Commercial Paper Programs”) pursuant to which the Euro Issuer may issue short-term unsecured commercial paper notes (the “ECP Notes” and, together with the USCP Notes, the “Commercial Paper”), which are guaranteed by the Company and are to be issued outside of the United States. The maturities of the ECP Notes will vary, but may not exceed 183 days from the date of issue. The ECP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom or a premium thereto and bear varying interest rates on a fixed or floating basis. The ECP Notes may be issued in Euros, Sterling, U.S. dollars or other currencies. In addition, effective April 14, 2020 through March 22, 2021, a subsidiary of the Company was able to issue ECP Notes through the Bank of England’s COVID Corporate Financing Facility (the “BOE Facility”). The BOE Facility expired on March 22, 2021, although the Company did not borrow under the BOE Facility. The maximum aggregate principal amount outstanding of ECP Notes at any time is $2,000.0. At December 31, 2021 and 2020, there were no ECP Notes outstanding under the Euro Commercial Paper Program.

Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the Revolving Credit Facility, as of December 31, 2021, the authorization from the Board limits the maximum principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper or similar programs, along with outstanding amounts under the Revolving Credit Facility, at any time to $2,500.0 in the aggregate. The Commercial Paper Programs are rated A-2 by Standard & Poor’s and P-2 by Moody’s and, based on the Board’s authorization described above, are currently backstopped by the Revolving Credit Facility, as amounts undrawn under the Company’s Revolving Credit Facility are available to repay Commercial Paper, if necessary. Net proceeds of the issuances of Commercial Paper are expected to be used for general corporate purposes. The Commercial Paper is classified as long-term debt in the accompanying Consolidated Balance Sheets since the Company has the intent and ability to refinance the Commercial Paper on a long-term basis using the Company’s Revolving Credit Facility. The Commercial Paper is actively traded and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The carrying value of Commercial Paper borrowings approximates their fair value.

U.S. Senior Notes

On September 14, 2021, the Company issued $750.0 principal amount of unsecured 2.200% Senior Notes due September 15, 2031 at 99.634% of face value (the “2031 Senior Notes”).

On September 4, 2019, the Company commenced tender offers (the “Tender Offers”) to purchase for cash any and all of the Company’s then outstanding (i) $375.0 principal amount of the 2021 Senior Notes and (ii) $500.0 principal amount of the 2022 Senior Notes. On September 11, 2019, as a result of the Tender Offers, the Company accepted for payment $147.3 aggregate principal amount of the 2021 Senior Notes and $205.0 aggregate principal amount of the 2022 Senior Notes for 101.9% and 104.5% of par value, respectively (collectively, the “Tendered Notes”), plus accrued and unpaid interest to, but not including, the settlement date of the Tender Offers. The total consideration for the Tendered Notes was $368.8, which in addition to the Tendered Notes, included $13.4 of premiums and fees paid related to the early extinguishment of debt and $3.1 of accrued interest. For the year ended December 31, 2019, the Company recorded a loss on early debt extinguishment of $14.3 ($12.5 after-tax, or $0.02 per diluted share) within Loss on early extinguishment of debt on the accompanying Consolidated Statements of Income.

The fair value of each series of Senior Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The Company’s Senior Notes impose certain obligations on the Company and prohibit various actions by the Company unless it satisfies certain financial requirements.
