Senior Notes

In March 2021, we issued $350 million of 3.625% Senior Notes due in 2029 (2029 Senior Notes). We may redeem the 2029 Senior Notes, in whole or in part, prior to March 15, 2024, at a redemption price equal to 100% of the principal amount thereof plus a “make-whole” premium set forth in the indenture governing our 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. On or after March 15, 2024, we may, at our option on one or more occasions, redeem all or any portion of these notes at the redemption prices set forth in the indenture governing the 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. The indenture governing the 2029 Senior Notes contains certain covenants that, among other things, limit our ability to grant liens to secure indebtedness, engage in sale and leaseback transactions, merge or consolidate or sell all or substantially all of our assets. If we are subject to a "change of control," as defined in the indenture governing our 2029 Senior Notes, we are required to offer to repurchase the 2029 Senior Notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to, but not including, the date of purchase. The indenture governing the 2029 Senior Notes contains customary events of default, including failure to make required payments on the 2029 Senior Notes, failure to comply with certain agreements or covenants contained in the indenture governing our 2029 Senior Notes, failure to pay or acceleration of certain other indebtedness and certain events of bankruptcy and insolvency. An event of default in the indenture allows either the indenture trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding 2029 Senior Notes to accelerate, or in certain cases, automatically causes the acceleration of, the amounts due under the 2029 Senior Notes.

Deferred debt costs are amortized over the life of the related debt using a straight-line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other non-operating items.

Credit Facilities

In November 2022, LP entered into a Second Amended and Restated Credit Agreement with American AgCredit, PCA, as administrative agent and sole lead arranger, CoBank, ACB, as letter of credit issuer, and certain other lender parties (the Credit Agreement), relating to its revolving credit facility (as amended, the Amended Credit Facility). The Credit Agreement provides for a revolving credit facility in the principal amount of up to $550 million, with a $60 million sub-limit for letters of credit. The Credit Agreement amended and restated the Amended and Restated Credit Agreement entered into by the Company and certain other parties dated as of June 27, 2019, as amended prior to the effectiveness of the Credit Agreement (as defined above), in its entirety to, among other things, (i) reflect the release of the collateral that secures the indebtedness evidenced by the Credit Agreement as a result of the Company’s obtaining an Investment Grade rating in November 2022 (which collateral may be reinstated from time to time in accordance with the terms of the Credit Agreement), (ii) extend the maturity date to November 29, 2028, (iii) make certain changes to effect a transition from the LIBOR interest rate benchmark to Term SOFR Rate (as defined in the Credit Agreement) and (iv) provide for certain other modifications (including modifications to certain basket and threshold levels in the negative covenants) as set forth in the Credit Agreement.

There were no outstanding amounts borrowed under the Amended Credit Facility as of December 31, 2023. Revolving borrowings under the Amended Credit Facility accrue interest, at our option, at either (a) a “base rate” plus a margin of 0.500% to 1.500% or (b) Adjusted Term SOFR (i.e., Term SOFR Rate plus an adjustment of 0.10%) plus a margin of 1.500% to 2.500%. The Amended Credit Facility also includes an unused commitment fee, due quarterly, ranging from 0.200% to 0.425%. The applicable margins and fees within these ranges are based on our ratio of consolidated Earnings before interest, taxes, depreciation and amortization (EBITDA) to cash interest charges. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (ii) the U.S. prime rate, and (iii) one-month Adjusted Term SOFR plus 1.0%.

The Credit Agreement contains various restrictive covenants and customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder. The Credit Agreement also contains financial covenants that, among other things, require us and our consolidated subsidiaries to have, as of the end of each fiscal quarter, a capitalization ratio (i.e., funded debt less unrestricted cash to total capitalization) of no more than 57.5%.

In March 2020, LP entered into a letter of credit facility agreement (the Letter of Credit Facility) with Bank of America, N.A., which provides for the funding of letters of credit up to an aggregate outstanding amount of $20 million, which may be secured by certain cash collateral of LP. The Letter of Credit Facility includes quarterly a letter of credit fee in an amount equal to 1.875% of the daily available amount to be drawn on each letter of credit issued under the facility; provided, that if all letters of credits issued under the Letter of Credit Facility have been cash collateralized, the applicable rate of the letter of credit fee is reduced to 0.500%. The Letter of Credit Facility is subject to similar affirmative, negative, and financial covenants as those set forth in the Credit Agreement, including capitalization ratio covenants.

As of December 31, 2023, we were in compliance with all financial covenants under the 2029 Senior Notes, the Credit Agreement and the Letter of Credit Facility.

Deferred debt costs are amortized over the life of the related debt using a straight-line basis, which approximates the effective interest method. Included in such amortized amounts are deferred debt costs associated with our Amended Credit Facility of $3 million, which are recorded within other assets on our Consolidated Balance Sheets. We amortized deferred debt costs of $1 million for each of the years ended December 31, 2023, 2022, and 2021.

The weighted average interest rate for all long-term debt at both December 31, 2023 and 2022 was approximately 3.6%. Required repayment of principal for long-term debt is as follows (dollars in millions):

We estimated the 2029 Senior Notes to have a fair value of $314 million and $306 million at December 31, 2023 and 2022, respectively, based upon market quotations. Fair values were based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates (Level 1 in the U.S. GAAP fair value hierarchy).
