Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation & Description of Business	BASIS OF PRESENTATION & DESCRIPTION OF BUSINESS Organization Core & Main , Inc. (“Core & Main”) is a Delaware corporation that was incorporated on April 9, 2021 for the purpose of facilitating an initial public offering and other related transactions, as described below, in order to carry on the business of Core & Main Holdings, LP, a Delaware limited partnership (“Holdings”), and its consolidated subsidiaries. Core & Main is a holding company and its primary material asset is its ownership interest in Holdings, a portion of which is held indirectly through CD&R WW, LLC. Holdings has no operations and no material assets of its own other than its indirect ownership interest in Core & Main LP, a Florida limited partnership, the legal entity that conducts the operations of Core & Main. Core & Main, together with its wholly-owned subsidiaries, including Holdings and its consolidated subsidiaries, are referred to as the “Company”. The Company is a leader in advancing reliable infrastructure with local service, nationwide.

On June 12, 2023, a secondary public offering of 14,000,000 shares of Class A common stock on behalf of the Selling Stockholders was completed at a price to the public of $28.215 per share (the “June 2023 Secondary Offering” and, together with the April 2023 Secondary Offering, the “Secondary Offerings”) .

Concurrently with the completion of the June 2023 Secondary Offering, (i) the Company repurchased from the Selling Stockholders an aggregate of 3,125,728 shares of our Class A common stock, with Holdings redeeming from the Company a corresponding number of Partnership Interests, and (ii) Holdings redeemed from one of the Selling Stockholders 1,874,272 Partnership Interests, with the Company repurchasing a corresponding number of shares of our Class B common stock from such Selling Stockholder for no additional consideration, with each repurchase of Class A common stock and redemption of Partnership Interests at the same price per share of $28.215 paid by the underwriter to the Selling Stockholders in the June 2023 Secondary Offering for total consideration paid of $141 million (collectively, the "June 2023 Repurchase Transaction" and, together with the April 2023 Repurchase Transaction, the “Repurchase Transactions”). The Company did not receive any of the proceeds from the Secondary Offerings.

The Original Limited Partners are defined as CD&R Waterworks Holdings, the Former Limited Partners and Management Feeder and represent the direct and indirect owners of Holdings prior to the Reorganization Transactions and the IPO. Basis of Presentation The accompanying unaudited condensed consolidated financial statements present the results of operations, financial position and cash flows of Core & Main and its subsidiaries, which includes the consolidated financial statements of Holdings and its consolidated subsidiary, Core & Main LP, as the legal entity that conducts the operations of the Company. Holdings is considered a variable interest entity. Core & Main is the primary beneficiary and general partner of Holdings and has decision making authority that significantly affects the economic performance of Holdings. As a result, Core & Main consolidates the consolidated financial statements of Holdings. All intercompany balances and transactions have been eliminated in consolidation. The Company records non-controlling interests related to Partnership Interest held by the Continuing Limited Partners in Holdings on its consolidated statements of operations and comprehensive income. The Partnership Interests held by the Continuing Limited Partners are reflected as non-controlling interests in Core & Main’s consolidated Balance Sheets. In management’s opinion, the unaudited condensed consolidated financial information for the interim periods presented include all normal recurring adjustments necessary for a fair statement of the Company's results of operations, financial position and cash flows, which include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim unaudited condensed consolidated financial statements may not be the same as those for the full year. The January 29, 2023 condensed consolidated Balance Sheet was derived from audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the fiscal year ended January 29, 2023 included in our 2022 Annual Report on Form 10-K. Fiscal Year The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to January 31 st . Quarters within the fiscal year include 13-week periods, unless a fiscal year includes a 53 rd week, in which case the fourth quarter of the fiscal year will be a 14-week period. Each of the three months ended July 30, 2023 and three months ended July 31, 2022 included 13 weeks and each of the six months ended July 30, 2023 and six months ended July 31, 2022 included 26 weeks. The current fiscal year ending January 28, 2024 (“fiscal 2023”) will include 52 weeks. Estimates Management has made a number of estimates and assumptions relating to the reporting of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses in preparing the elements of these financial statements in conformity with U.S. GAAP. Actual results could differ from these estimates. Accounting Policies The Company’s significant accounting policies are discussed in Note 2 to the audited consolidated financial statements in our 2022 Annual Report on Form 10-K. There have been no significant changes to these policies which have had a material impact on the Company’s interim unaudited condensed consolidated financial statements and related notes during the three and six months ended July 30, 2023.

The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by ASU 2020-04 are effective for prospective contract modifications made and qualifying hedging relationships entered into as of March 12, 2020 through December 31, 2024. In February 2023, the Company amended the terms of the Senior Term Loan Facility (as defined in Note 6) in order to implement a forward-looking rate based on the term secured overnight financing rate (“Term SOFR”) in lieu of LIBOR. In addition, in February 2023, the Company amended the terms of the related interest rate swap to adjust the fixed interest rate and receive payments based upon the one-month Term SOFR rate, based on notional amounts associated with borrowings under the Senior Term Loan Facility. There were no changes to the principal balances or maturity dates of these debt instruments. The amendments to the Senior Term Loan Facility and related interest rate swap are related to the replacement of the reference rate, therefore these amendments are subject to the practical expedients in ASU 2020-04. In July 2022, the Company amended the terms of the Senior ABL Credit Facility (as defined in Note 6) in order to, among other things, implement a forward-looking rate based on Term SOFR in lieu of LIBOR. The guidance of ASU 2020-04 did not have an impact on the assessment of the Senior ABL Credit Facility amendment. At the time of a qualifying future transaction that replaces LIBOR with a new interest rate index, the Company will consider the application of ASU 2020-04.

The following table represents the preliminary allocation of the transaction price to the fair value of identifiable assets acquired and liabilities assumed in the Fiscal 2023 Acquisitions and final allocation of the transaction price to the fair value of identifiable assets acquired and liabilities assumed in the Fiscal 2022 Acquisitions: Fiscal 2023 Acquisitions Fiscal 2022 Acquisitions Cash $ 5 $ — Receivables 28 4 Inventories 38 13 Intangible assets 76 12 Goodwill 17 12 Property, plant and equipment 24 3 Operating lease right-of-use assets 7 4 Other assets, current and non-current 4 — Total assets acquired 199 48 Accounts payable 9 1 Deferred income taxes 8 — Operating lease liabilities, current and non-current 7 4 Other liabilities, current and non-current 16 1 Net assets acquired $ 159 $ 42 The net outflow of cash in respect of the purchase of businesses is as follows: Fiscal 2023 Acquisitions Fiscal 2022 Acquisitions Net assets acquired $ 159 $ 42 Less: Working capital adjustment (3) — Less: Cash acquired in acquisition (5) — Total consideration, net of cash; investing cash outflow $ 151 $ 42 In the above transactions, to the extent applicable, the excess of purchase price over net tangible and intangible assets acquired resulted in goodwill, which represents the assembled workforce and anticipated long-term growth in new markets, customers and products. Goodwill of $3 million and $12 million associated with the Fiscal 2023 Acquisitions and Fiscal 2022 Acquisitions, respectively, are fully deductible by the Company for U.S. income tax purposes. Intangible Assets For the Fiscal 2023 Acquisitions and Fiscal 2022 Acquisitions discussed above, the Company valued the customer relationships as intangible assets acquired. The customer relationship intangible assets represent the value associated with those customer relationships in place at the date of the Fiscal 2023 Acquisitions and Fiscal 2022 Acquisitions. The Company valued the customer relationships using an excess earnings method using various inputs such as customer attrition rate, revenue growth rate, gross margin percentage and discount rate. Cash flows associated with the existing relationships are expected to diminish over time due to customer turnover. The Company reflected this expected diminishing cash flow through the utilization of an annual customer attrition rate assumption and in its method of amortization. A summary of the intangible asset acquired and assumptions utilized in the valuation for the Fiscal 2023 Acquisitions and Fiscal 2022 Acquisitions is as follows: Intangible Asset Amount Weighted Average Amortization Period Weighted Average Discount Rate Weighted Average Attrition Rate Customer Relationships Fiscal 2023 Acquisitions $ 76 10 years 16.2 % 12.6 % Fiscal 2022 Acquisitions 12 10 years 14.4 % 13.5 %

Goodwill represents the excess of purchase price over the fair value of net assets acquired. The Company does not amortize goodwill, but does assess the recoverability of goodwill on an annual basis during the fourth quarter. If an event occurs or circumstances change that would “more likely than not” reduce the fair value of a reporting unit below its carrying value, an interim impairment test would be performed between annual tests.

The Senior Term Loan Facility requires quarterly principal payments, payable on the last business day of each fiscal quarter in an amount equal to approximately 0.25% of the original principal amount of the Senior Term Loan Facility. The remaining balance is payable upon final maturity of the Senior Term Loan Facility on July 27, 2028. The Senior Term Loan Facility bears interest at a rate equal to (i) Term SOFR plus, in each case, an effective applicable margin of 2.60% or (ii) the base rate, which will be the highest of (x) the corporate base rate established by the administrative agent as its prime rate in effect at its principal office in New York City from time to time, (y) the overnight federal funds rate plus 0.50% per annum and (z) one-month Term SOFR (adjusted for maximum reserves) plus 1.00% per annum, plus, in each case, an applicable margin of 1.50%. The Senior Term Loan Facility is subject to a Term SOFR “floor” of 0.00%. The weighted average interest rate, excluding the effect of the interest rate swap, of Core & Main LP’s outstanding borrowings under the Senior Term Loan Facility as of July 30, 2023 was 7.84%. See further discussion of the interest rate swap below. Based on quotes from financial institutions (i.e., level 2 of the fair value hierarchy), the fair value of the Senior Term Loan Facility wa s $1,464 million as of July 30, 2023 . Asset-Based Credit Facility Core & Main LP has a senior asset-based revolving credit facility with a borrowing capacity of up to $1,250 million, subject to borrowing base availability, with a maturity date of July 27, 2026 (the “Senior ABL Credit Facility”). Borrowings under the Senior ABL Credit Facility bear interest at either a Term SOFR rate plus an applicable margin ranging from 1.25% to 1.75%, or an alternate base rate plus an applicable margin ranging from 0.25% to 0.75%, depending on the borrowing capacity under the Senior ABL Credit Facility. Additionally, Core & Main LP pays a fee of 0.25% on unfunded commitments under the Senior ABL Credit Facility. As of July 30, 2023, there was $115 million outstanding under the Senior ABL Credit Facility with a weighted average interest rate of 7.71%. The book value of the Senior ABL Credit Facility approximates fair value due to the variable interest rate nature of these borrowings. The aforementioned debt agreements include customary affirmative and negative covenants, which include, among other things, restrictions on Core & Main LP’s ability to make distributions, pay dividends, create liens, incur additional indebtedness, make investments, dispose of assets and merge or consolidate with any other person. The Senior Term Loan Facility may require accelerated repayment based upon cash flows generated in excess of operating and investing requirements when the Consolidated Secured Leverage Ratio (as defined in the agreement governing the Senior Term Loan Facility) is greater than or equal to 3.25. In addition, the Senior ABL Credit Facility requires Core & Main LP to comply with a consolidated fixed charge coverage ratio of greater than or equal to 1.00 when availability under the Senior ABL Credit Facility is less than 10.0% of the lesser of (i) the then applicable borrowing base or (ii) the then aggregate effective commitments. The Company was in compliance with all debt covenants as of July 30, 2023. Substantially all of Core & Main LP’s assets are pledged as collateral for the Senior Term Loan Facility and the Senior ABL Credit Facility. The aggregate amount of debt payments for the remainder of fiscal 2023 and the next four full fiscal years are as follows: Fiscal 2023 $ 7 Fiscal 2024 15 Fiscal 2025 15 Fiscal 2026 130 Fiscal 2027 15 Interest Rate Swaps On February 26, 2023, Core & Main LP amended the terms of the instrument to adjust the fixed interest rate to 0.693% and receive payments based upon the one-month Term SOFR rate, based on notional amounts associated with borrowings under the Senior Term Loan Facility. The measurement period of the interest rate swap commenced on July 27, 2021 with a notional amount of $900 million as of July 30, 2023. The notional amount decreases to $800 million on July 27, 2024 and $700 million on July 27, 2025 through the instrument maturity on July 27, 2026. This instrument is intended to reduce the Company's exposure to variable interest rates under the Senior Term Loan Facility. As of July 30, 2023, this instrument resulted in an effective fixed rate of 3.293%, based upon the 0.693% fixed rate plus an effective applicable margin of 2.60%, on $900 million of borrowings under the Senior Term Loan Facility. The fair value of this cash flow interest rate swap was an $85 million and $84 million asset as of July 30, 2023 and January 29, 2023, respectively, which is included within other assets in the Balance Sheet. Fair value is based upon the present value of future cash flows under the terms of the contract and observable market inputs (level 2). Significant inputs used in determining fair value include forward-looking one-month Term SOFR rates and the discount rate applied to projected cash flows.

Income Taxes	INCOME TAXES For the three months ended July 30, 2023 and July 31, 2022, the Company’s effective tax rate was 19.6% and 17.3%, respectively. For the six months ended July 30, 2023 and July 31, 2022, the Company's effective tax rate was 19.3% and 17.6%, respectively. The variations between the Company's estimated effective tax rate and the U.S. and state statutory rates are primarily due to the portion of the Company's earnings attributable to non-controlling interests following the Reorganization Transactions partially offset by certain permanent book-tax differences. Tax Receivable Agreements and Reorganization Transactions In connection with the Reorganization Transactions and the IPO, Core & Main entered into a tax receivable agreement with the Former Limited Partners (the “Former Limited Partners Tax Receivable Agreement”) and a tax receivable agreement with the Continuing Limited Partners (the “Continuing Limited Partners Tax Receivable Agreement”) (collectively, the “Tax Receivable Agreements”). Core & Main expects to generate additional tax attributes, associated with future exchanges of Partnership Interests by Continuing Limited Partners, that will reduce amounts that it would otherwise pay in the future to various tax authorities. The Tax Receivable Agreements provide for the payment to either the Former Limited Partners or Continuing Limited Partners, or their permitted transferees, of 85% of the tax benefits realized by the Company, or in some circumstances are deemed to realize. The Company recorded payables to related parties pursuant to the Tax Receivable Agreements of $242 million and $185 million as of July 30, 2023 and January 29, 2023, respectively. In fiscal 2023, the Company had a financing cash outflow related to the payment of $5 million under the Former Limited Partner Tax Receivable Agreements. Payments under the Tax Receivable Agreements within the next 12 months are expected to be $11 million, which is included within other current liabilities in the Balance Sheet. The actual amount and timing of any payments under the Tax Receivable Agreements will vary depending upon a number of factors, including the timing of exchanges by the holders of Partnership Interests, the amount of gain recognized by such holders of Partnership Interests, the amount and timing of the taxable income the Company generates in the future and the federal tax rates then applicable. Assuming (i) that the Continuing Limited Partners exchanged all of their Partnership Interests at $32.33 per share of our Class A common stock (the closing stock price on July 28, 2023), (ii) no material changes in relevant tax law, (iii) a constant corporate tax rate of 25.1%, which represents a pro forma tax rate that includes a provision for U.S. federal income taxes and assumes the highest statutory rate apportioned to each state and local jurisdiction and (iv) that the Company earns sufficient taxable income in each year to realize on a current basis all tax benefits that are subject to the Continuing Limited Partners Tax Receivable Agreement, the Company would recognize a deferred tax asset (subject to offset with existing deferred tax liabilities) of approximately $614 million and a Continuing Limited Partners Tax Receivable Agreement liability of approximately $522 million, payable to the Continuing Limited Partners over the life of the Continuing Limited Partners Tax Receivable Agreement. The full exchange by the Continuing Limited Partners will also decrease Core & Main's aforementioned deferred tax asset associated with its investment in Holdings by $141 million. The foregoing amounts are estimates and subject to change.

Noncontrolling Interest [Abstract]
Non-controlling Interests	NON-CONTROLLING INTERESTS Core & Main is the general partner of Holdings and operates and controls all of the business and affairs of Holdings and, through Holdings and its subsidiaries, conducts the Company's business. Accordingly, Core & Main consolidates the consolidated financial statements of Holdings and attributes a portion of net income and equity of Holdings to non-controlling interests related to the vested Partnership Interests held by the Continuing Limited Partners. Income or loss is attributed to the non-controlling interests based on the weighted average percentage of Partnership Interests held by Continuing Limited Partners, excluding unvested Partnership Interests held by Management Feeder, relative to all Partnership Interests of Holdings during the period following the Reorganization Transactions. Holdings equity is attributed to non-controlling interests based on the Partnership Interests held by Continuing Limited Partners, excluding unvested Partnership Interests held by Management Feeder, relative to all Partnership Interests as of the balance sheet date. The non-controlling interests’ ownership percentage may fluctuate over time as the Continuing Limited Partners exchange Partnership Interests, together with the retirement of a corresponding number of shares of Class B common stock, for shares of Class A common stock and Partnership Interests held by Management Feeder vest. The following table summarizes the ownership of Partnership Interests of Holdings (excluding unvested Partnership Interests held by Management Feeder): Partnership Interests Ownership Percentage Core & Main Continuing Limited Partners Total Core & Main Continuing Limited Partners Total Balances as of January 29, 2023 172,765,161 72,471,473 245,236,634 70.4 % 29.6 % 100.0 % Retirement of Partnership Interests (12,502,911) (7,497,089) (20,000,000) 0.7 (0.7) — Issuance of Partnership Interests 233,337 — 233,337 0.1 (0.1) — Exchange of Partnership Interests 8,095,403 (8,098,573) (3,170) 3.6 (3.6) — Vesting of Partnership Interests — 296,002 296,002 (0.1) 0.1 — Balances as of July 30, 2023 168,590,990 57,171,813 225,762,803 74.7 % 25.3 % 100.0 %

Earnings Per Share [Abstract]
Basic and Diluted Earnings Per Share	BASIC AND DILUTED EARNINGS PER SHARE The following table presents the calculation of basic and diluted earnings per share for the three and six months ended July 30, 2023 and July 31, 2022. Basic earnings per share is computed by dividing net income attributable to Core & Main for the period by the weighted average number of shares of Class A common stock outstanding during the same period. Shares of Class A common stock issued or redeemed during the period were weighted for the portion of the period in which the shares of Class A common stock were outstanding. The Company did not apply the two-class method because shares of Class B common stock do not participate in earnings or losses of Core & Main. As a result, the shares of Class B common stock are not considered participating securities and are not included in the weighted average shares outstanding for purposes of earnings per share. Net income allocated to holders of non-controlling interests was excluded from net income available to the Class A common stock. There were no preferred dividends and no shares of preferred stock outstanding for the period. The diluted earnings per share calculation includes the basic weighted average number of shares of Class A common stock outstanding plus the dilutive impact of potential outstanding shares of Class A common stock that would be issued upon exchange of Partnership Interests, together with the retirement of a corresponding number of shares of Class B common stock, under the if-converted method, if dilutive. The treasury stock method is applied to outstanding awards, including unvested Partnership Interests and outstanding stock appreciation rights, restricted stock units and stock options.

During the three and six months ended July 31, 2022, the Company had less than $1 million and $1 million in purchases of product, respectively, from affiliates of CD&R, including other companies invested in by funds affiliated with the CD&R Funds. There were no amounts payable to affiliates of CD&R at July 30, 2023 and January 29, 2023. There were $2 million and $7 million in sales to affiliates of CD&R for the three and six months ended July 30, 2023, respectively. There was $1 million and $2 million in sales to affiliates of CD&R for the three and six months July 31, 2022, respectively. The Company had $1 million and $2 million amounts receivable from affiliates of CD&R at July 30, 2023 and January 29, 2023, respectively. Tax Receivable Agreements In connection with the Reorganization Transactions, Core & Main entered into the Former Limited Partners Tax Receivable Agreement with the Former Limited Partners and the Continuing Limited Partners Tax Receivable Agreement with the Continuing Limited Partners. See further discussion in Note 7. Exchange Agreement In connection with the Reorganization Transactions, Core & Main entered into the Exchange Agreement, dated as of July 22, 2021 (as amended, the “Exchange Agreement”), by and among Core & Main Holdings, LLC and Core & Main Management Feeder, LLC. Pursuant to the Exchange Agreement, the Continuing Limited Partners (or their permitted transferees) will have the right, subject to the terms of the Exchange Agreement, to exchange their Partnership Interests, together with the retirement of a corresponding number of shares of Class B common stock, for shares of Class A common stock generally on a one-for-one basis or for cash in limited circumstances as specified in the Exchange Agreement. Holders of Partnership Interests will not have the right to exchange Partnership Interests if Core & Main determines that such exchange would be prohibited by law or regulation or would violate other agreements with Core & Main or its subsidiaries to which the holder of Partnership Interests may be subject. Core & Main may also refuse to honor any request to effect an exchange if it determines such exchange would pose a material risk that Holdings would be treated as a “publicly traded partnership” for U.S. federal income tax purposes. Notwithstanding the foregoing, the Continuing Limited Partners are generally permitted to exchange Partnership Interests, subject to the terms of the Exchange Agreement. The Exchange Agreement also provides that, in connection with any such exchange, to the extent that Holdings has, since consummation of the Reorganization Transactions and the IPO, made distributions to the applicable Continuing Limited Partner that are proportionately lesser or greater than the distributions made to Core & Main, on a pro rata basis, the number of shares of Class A common stock to be issued or cash to be paid to such Continuing Limited Partner will be adjusted to take into account the amount of such discrepancy that is allocable to the Partnership Interests, and Class B common stock, subject to such exchange. As of July 30, 2023, the Company had shareholder receivables of $8 million recorded within additional paid in capital related to distributions in excess of shareholders’ pro rata share. Core & Main expects to cause Holdings to make distributions to its partners in such a manner as generally to limit increases to the number of shares of Class A common stock to be issued or cash to be paid to exchanging Continuing Limited Partners in connection with the adjustment described in the preceding sentence.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation - Consolidation	The accompanying unaudited condensed consolidated financial statements present the results of operations, financial position and cash flows of Core & Main and its subsidiaries, which includes the consolidated financial statements of Holdings and its consolidated subsidiary, Core & Main LP, as the legal entity that conducts the operations of the Company. Holdings is considered a variable interest entity. Core & Main is the primary beneficiary and general partner of Holdings and has decision making authority that significantly affects the economic performance of Holdings. As a result, Core & Main consolidates the consolidated financial statements of Holdings. All intercompany balances and transactions have been eliminated in consolidation. The Company records non-controlling interests related to Partnership Interest held by the Continuing Limited Partners in Holdings on its consolidated statements of operations and comprehensive income. The Partnership Interests held by the Continuing Limited Partners are reflected as non-controlling interests in Core & Main’s consolidated Balance Sheets.
Basis of Presentation - Accounting	In management’s opinion, the unaudited condensed consolidated financial information for the interim periods presented include all normal recurring adjustments necessary for a fair statement of the Company's results of operations, financial position and cash flows, which include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim unaudited condensed consolidated financial statements may not be the same as those for the full year. The January 29, 2023 condensed consolidated Balance Sheet was derived from audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the fiscal year ended January 29, 2023 included in our 2022 Annual Report on Form 10-K.
Fiscal Year	Fiscal Year The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to January 31 st . Quarters within the fiscal year include 13-week periods, unless a fiscal year includes a 53 rd
Estimates	Estimates Management has made a number of estimates and assumptions relating to the reporting of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses in preparing the elements of these financial statements in conformity with U.S. GAAP. Actual results could differ from these estimates.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Reference Rate Reform - In March 2020, the Financial Accounting Standards Board issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”). The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by ASU 2020-04 are effective for prospective contract modifications made and qualifying hedging relationships entered into as of March 12, 2020 through December 31, 2024. In February 2023, the Company amended the terms of the Senior Term Loan Facility (as defined in Note 6) in order to implement a forward-looking rate based on the term secured overnight financing rate (“Term SOFR”) in lieu of LIBOR. In addition, in February 2023, the Company amended the terms of the related interest rate swap to adjust the fixed interest rate and receive payments based upon the one-month Term SOFR rate, based on notional amounts associated with borrowings under the Senior Term Loan Facility. There were no changes to the principal balances or maturity dates of these debt instruments. The amendments to the Senior Term Loan Facility and related interest rate swap are related to the replacement of the reference rate, therefore these amendments are subject to the practical expedients in ASU 2020-04. In July 2022, the Company amended the terms of the Senior ABL Credit Facility (as defined in Note 6) in order to, among other things, implement a forward-looking rate based on Term SOFR in lieu of LIBOR. The guidance of ASU 2020-04 did not have an impact on the assessment of the Senior ABL Credit Facility amendment. At the time of a qualifying future transaction that replaces LIBOR with a new interest rate index, the Company will consider the application of ASU 2020-04.
