All of the notes and debentures above are senior indebtedness and, other than the 7.75% Notes due 2029, are redeemable at our option.

On September 18, 2020, we issued $300 million of 2.0% Notes due October 1, 2030 (the "2030 Notes") and received proceeds of $300 million, net of discount, for the issuance of the 2030 Notes. Also on September 18, 2020, we issued an incremental $100 million of our existing 4.5% Notes due May 15, 2047 (the "2047 Notes") and received proceeds of $119 million, including a premium, for the issuance of the 2047 Notes. The incremental $100 million formed a single series with the existing $300 million of 4.5% Notes due May 15, 2047. The 2030 Notes and 2047 Notes are senior indebtedness and are redeemable at our option at the applicable redemption price. On September 29, 2020, proceeds from the debt issuances were used to repay and early retire $400 million of our 3.5% Notes due April 1, 2021. In connection with this early retirement, we incurred a loss on debt extinguishment of $6 million, which was recorded as interest expense in our consolidated statement of operations.

On December 19, 2019, proceeds from the UKWG and Milgard divestitures were used to repay and early retire $201 million of our 7.125% Notes due March 15, 2020. In connection with this early retirement, we incurred a loss on debt extinguishment of $2 million for the year ended December 31, 2019, which was recorded as interest expense in our consolidated statement of operations.

On April 16, 2018, we repaid and retired all of our $114 million, 6.625% Notes on the scheduled repayment date.

On March 13, 2019, we entered into a credit agreement (the “Credit Agreement”) with an aggregate commitment of $1.0 billion and a maturity date of March 13, 2024. Under the Credit Agreement, at our request and subject to certain conditions, we can increase the aggregate commitment up to an additional $500 million with the current lenders or new lenders. Upon entry into the Credit Agreement, our credit agreement dated March 28, 2013, as amended, with an aggregate commitment of $750 million, was terminated.

The Credit Agreement provides for an unsecured revolving credit facility available to us and one of our foreign subsidiaries, in U.S. dollars, European euros, British Pounds Sterling, Canadian dollars and certain other currencies for revolving credit loans, swingline loans and letters of credit. Borrowings under the revolving credit loans denominated in any agreed upon currency other than U.S. dollars are limited to $500 million, equivalent. We can also borrow swingline loans up to $100 million and obtain letters of credit of up to $25 million; outstanding letters of credit under the Credit Agreement reduce our borrowing capacity. At December 31, 2020, we had no outstanding standby letters of credit under the Credit Agreement.

L. DEBT (Concluded)

Revolving credit loans bear interest under the Credit Agreement, at our option, at (A) a rate per annum equal to the greater of (i) the JPMorgan Chase Bank, N.A. prime rate, (ii) the Federal Reserve Bank of New York effective rate plus 0.50% and (iii) if available, adjusted LIBO Rate plus 1.0% (the "Alternative Base Rate"); plus an applicable margin based upon our then-applicable corporate credit ratings; or (B) if available, adjusted LIBO Rate plus an applicable margin based upon our then-applicable corporate credit ratings. The foreign currency revolving credit loans bear interest at a rate equal to adjusted LIBO Rate, if available, plus an applicable margin based upon our then-applicable corporate credit ratings.

The Credit Agreement contains financial covenants requiring us to maintain (A) a net leverage ratio, as adjusted for certain items, not exceeding 4.0 to 1.0, and (B) a minimum interest coverage ratio, as adjusted for certain items, not less than 2.5 to 1.0.

In order for us to borrow under the Credit Agreement, there must not be any default in our covenants in the Credit Agreement (i.e., in addition to the two financial covenants, principally limitations on subsidiary debt, negative pledge restrictions, legal compliance requirements and maintenance of properties and insurance) and our representations and warranties in the Credit Agreement must be true in all material respects on the date of borrowing (i.e., principally no material adverse change or litigation likely to result in a material adverse change, since December 31, 2018, no material ERISA or environmental non-compliance, and no material tax deficiency). We were in compliance with all covenants and no borrowings were outstanding at December 31, 2020.

At December 31, 2020, the debt maturities during each of the next five years were as follows: 2021 – $3 million; 2022– $334 million; 2023 – $3 million; 2024 – $3 million and 2025 – $503 million.

Interest paid was $136 million, $157 million and $155 million in 2020, 2019 and 2018, respectively. These amounts exclude $5 million and $2 million of debt extinguishment costs related to the early retirement of debt, which were recorded as interest expense and paid in 2020 and 2019, respectively.
