On November 19, 2021, we amended the Note Purchase Agreement to among other things, facilitate the terms of the Receivables Securitization Facility.U.S. TRADE ACCOUNTS RECEIVABLE SECURITIZATION On November 19, 2021, we entered into a receivables purchase agreement and related transaction documents with Bank of America, N.A. and Wells Fargo Bank, N.A. to provide a receivables securitization facility (the “Receivables Securitization Facility”). The Receivables Securitization Facility is based on the securitization of our U.S. trade accounts receivable with a total availability of $300 million as of December 31, 2021. The interest rate on borrowings under the Receivables Securitization Facility is based on Bloomberg Short Term Bank Yield Index (“BSBY”) plus a margin. There is also a commitment fee we are required to pay on any unused portion of the facility. The Receivables Securitization Facility expires on November 17, 2023, unless extended by the parties and is recorded as a noncurrent liability as of December 31, 2021. The recorded amount of borrowings outstanding on the Receivables Securitization Facility approximates fair value because it can be redeemed on short notice and the interest rate floats. We consider these borrowings to be a Level 2 financial liability. Borrowings on the Receivables Securitization Facility are included within proceeds on long-term borrowings on the consolidated statement of cash flows. The Receivables Securitization Facility contains various customary affirmative and negative covenants, and it also contains customary default and termination provisions, which provide for acceleration of amounts owed under the Receivables Securitization Facility upon the occurrence of certain specified events.On February 1, 2022, we amended the Receivables Securitization Facility primarily to increase the total availability from $300 million to $500 million pursuant to the provisions of the existing agreement.   
On April 26, 2017, we entered into a receivables purchase agreement and related transaction documents with The Bank of Tokyo-Mitsubishi UFJ, Ltd., New York Branch and Wells Fargo Bank, N.A. to provide a receivables securitization facility with funding of up to $250 million. On December 17, 2018, we entered into an amendment on this facility, which changed the lending parties to Wells Fargo Bank, N.A. and Bank of America, N.A. and extended the maturity date from April 26, 2019, to December 17, 2020. The facility expired on December 17, 2020, and it was not renewed; however, we entered into a new receivables securitization facility in November 2021 as described above.SENIOR NOTESOn April 9, 2018, we issued senior unsecured notes (“Senior Notes”) through a public offering. The Senior Notes bear an annual interest rate of 4.20 percent payable semi-annually on April 15 and October 15, until maturity on April 15, 2028. Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, the Senior Notes have an effective yield to maturity of approximately 4.39 percent per annum. The fair value of the Senior Notes, excluding debt discounts and issuance costs, approximated $677.1 million as of December 31, 2021, based primarily on the market prices quoted from external sources. The carrying value of the Senior Notes was $594.2 million as of December 31, 2021. If the Senior Notes were measured at fair value in the financial statements, they would be classified as Level 2 in the fair value hierarchy. We may redeem the Senior Notes, in whole or in part, at any time and from time to time prior to their maturity at the applicable redemption prices described in the Senior Notes. Upon the occurrence of a “change of control triggering event” as defined in the Senior Notes (generally, a change of control of us accompanied by a reduction in the credit rating for the Senior Notes), we will generally be required to make an offer to repurchase the Senior Notes from holders at 101 percent of their principal amount plus accrued and unpaid interest to the date of repurchase. The Senior Notes were issued under an indenture that contains covenants imposing certain limitations on our ability to incur liens; enter into sales and leaseback transactions above certain limits; and consolidate, merge, or transfer substantially all of our assets and those of our subsidiaries on a consolidated basis. It also provides for customary events of default (subject in certain cases to customary grace and cure periods), which include among other things nonpayment, breach of covenants in the indenture, and certain events of bankruptcy and insolvency. If an event of default occurs and is continuing with respect to the Senior Notes, the trustee or holders of at least 25 percent in principal amount outstanding of the Senior Notes may declare the principal and the accrued and unpaid interest, if any, on all of the outstanding Senior Notes to be due and payable. These covenants and events of default are subject to a number of important qualifications, limitations, and exceptions that are described in the indenture. The indenture does not contain any financial ratios or specified levels of net worth or liquidity to which we must adhere.
