Significant Accounting Policies | Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition In accordance with ASC 606, Revenue from Contracts with Customers, the Company recognizes revenue for the sale of goods based on its assessment of when control transfers to our customers, which generally occurs upon shipment or delivery of the products. See Note 4, "Revenue from Contracts with Customers," for additional information. Customer Program Costs Customer programs and incentives are a common practice in our business. Our business incurs customer program costs to obtain favorable product placement, to promote sales of products and to maintain competitive pricing. These costs are recognized as either a reduction of revenue or within the selling, general and administrative expenses category, depending on the underlying nature of the cost. We record estimates to reduce revenue for customer programs and incentives, which are considered variable consideration, and include price discounts, volume-based incentives, promotions and cooperative advertising when revenue is recognized in order to determine the amount of consideration the Company will ultimately be entitled to receive. These estimates are based on historical and projected experience for each type of customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new products, store sell-through, merchandising support, levels of returns and customer training. Management periodically reviews accruals for these rebates and allowances, and adjusts accruals when circumstances indicate, typically as a result of a change in volume expectations. Cost of Products Sold Cost of products sold includes all costs to make products saleable, including the cost of materials, as well as labor costs, inbound freight, purchasing and receiving costs, inspection costs and internal transfer costs. In addition, all depreciation expense associated with assets used to manufacture products and make them saleable is included in cost of products sold. Selling, General and Administrative Expenses Selling, general and administrative expenses include advertising costs; marketing costs; selling costs, including commissions; research and development costs; shipping and handling costs, including warehousing costs; and general and administrative expenses. Shipping and handling costs included in selling, general and administrative expenses wer e $164.4 million, $169.4 million and $209.9 million in 2024, 2023 and 2022, respectively . Advertising costs, which amounted to $54.5 million, $65.0 million and $69.1 million in 2024, 2023 and 2022, respectively, are principally expensed as incurred. Advertising costs paid to customers as pricing rebates include product displays, marketing administration costs, media production costs and point of sale materials. Advertising costs recorded as a reduction to net sales, primarily cooperative advertising, were $18.5 million, $27.6 million and $29.4 million in 2024, 2023 and 2022, respectively. Advertising costs recorded in selling, general and administrative expenses were $36.0 million, $37.4 million and $39.7 million in 2024, 2023 and 2022, respectively. Stock-based Compensation Some of our associates participate in stock-based compensation plans sponsored by the Company. Stock based compensation plans may include stock options, restricted stock, restricted stock units, performance shares, performance units, other types of stock-based awards, and other cash-based compensation. Stock-based compensation expense, measured as the fair value of an award on the date of grant, is recognized in the financial statements over the period that an associate is required to provide services in exchange for the award. Stock-based compensation expense is recorded net of estimated forfeitures. The fair value of each option award is measured on the date of grant using the Black-Scholes option-pricing model. The fair value of each performance share award is based on the average of the high and low share prices on the date of grant and the probability of meeting performance targets. The fair value of each restricted stock unit granted is equal to the average of the high and low share prices on the date of grant. See Note 18, "Stock-Based Compensation," for additional information. Foreign Currency Translation Foreign currency balance sheet accounts are translated into U.S. dollars at the actual rates of exchange at the balance sheet date. Income and expenses are translated at the average rates of exchange in effect during the period for the foreign subsidiaries where the local currency is the functional currency. The related translation adjustments are made directly to a separate component of the accumulated other comprehensive loss caption in equity. Transactions denominated in a currency other than the functional currency of a subsidiary are translated into the functional currency with resulting transaction gains or losses recorded in other expense, net. Income Taxes The income tax expense in our Consolidated Financial Statements has been determined on a stand-alone return basis in accordance with ASC Topic 740, Income Taxes, which requires the recognition of income taxes using the liability method. The tax provision and current and deferred tax balances have been prepared on a separate-return basis as if the Company were a separate filer. The income taxes of the Company, as presented in the consolidated financial statements, may not be indicative of the income taxes that the Company will incur in the future. For taxable periods prior to and including the Separation, our operations were included in the consolidated U.S. federal and certain state and local income tax returns of Fortune Brands, as applicable. The Company filed separate foreign income tax returns. Post-Separation, our income tax provisions are calculated based on the Company’s operating footprint, as well as our tax return elections and assertions. Income tax liabilities related to unrecognized tax benefits (“UTBs”), including interest and penalties, are reported as a liability within the Consolidated Balance Sheets based upon tax authorities’ ability to assert the Company may be legally liable for UTBs. For taxable periods ended after the Separation, the Company filed consolidated U.S. federal income tax returns and various state and local income tax returns. The Company’s foreign income tax returns continue to be filed on a full-year basis. The Company is subject to income taxes in the U.S. and various foreign jurisdictions. The determination of the Company’s income tax positions involves consideration of uncertainties, changing fiscal policies, tax laws, court rulings, regulations and related legislation. Accordingly, significant management judgment is required in determining the provision for income taxes, deferred tax assets and liabilities, unrecognized tax benefits and the valuation allowance recorded against deferred tax assets. Deferred tax assets and liabilities are determined based on the differences between the financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The recognition and measurement of deferred tax asset and liability balances, and the corresponding deferred tax expense or benefit, are determined for each tax-paying component in each relevant jurisdiction. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the new tax rate is enacted. The Company recognizes liabilities for unrecognized tax benefits which are recognized if the weight of available evidence indicates that it is not more-likely-than-not that the positions will be sustained on examination, including resolution of the related appeals or litigation processes, if any. We record liabilities for uncertain income tax positions based on a two-step process. The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50 percent of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50 percent likelihood of being sustained, no tax benefit is recorded. Considerable management judgment is necessary to assess the inherent uncertainties related to the interpretations of complex tax laws, regulations and taxing authority rulings. For tax positions that have met the recognition threshold in the first step, we perform the second step of measuring the benefit to be recorded. The actual benefits ultimately realized may differ from our estimates. As of each balance sheet date, unrecognized tax benefits are reassessed and adjusted if the Company’s judgment changes as a result of new information, and changes in facts or circumstances. Changes in recognition and measurement estimates are recorded in the Consolidated Statements of Income and Consolidated Balance Sheets in the period in which such changes occur. We reduce our deferred tax assets by a valuation allowance if it is more likely than not that we will not realize some portion or all of the deferred tax assets. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance in the period in which such changes occur, which would reduce the provision for income taxes. The Company recognizes Global Intangible Low-Taxed Income (“GILTI”) tax as a period cost. The Company recognizes tax-related interest and penalties as a component of income tax expense. Earnings Per Share Earnings per common share is calculated by dividing net income attributable to MasterBrand by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share include the impact of all potentially dilutive securities outstanding during the year. Cash and Cash Equivalents We consider all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. We do not believe we are exposed to any significant credit risk on cash and cash equivalents. The carrying amounts of cash and cash equivalents approximate fair value. Allowances for Credit Losses Trade receivables are recorded at the stated amount, less allowances for discounts and credit losses. The allowances represent estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency) or discounts related to early payment of accounts receivable by our customers. The allowances for credit losses include provisions for certain customers where a risk of default has been specifically identified. In addition, the allowances include a provision for expected customer defaults on a general formula basis when it cannot yet be associated with specific customers. Expected credit losses are estimated using various factors, including the length of time the receivables are past due, historical collection experience and existing economic conditions. Inventories Inventories are stated at the lower of cost or net realizable value, cost being determined on a first-in, first-out basis and net realizable value being determined on the basis of replacement cost. Inventory costs include direct materials, including freight, labor and manufacturing overhead. Inventory provisions are recorded to reduce inventory to the net realizable dollar value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage and specific identification of items, such as product discontinuance, engineering and material changes, or regulatory-related changes. If actual market conditions differ from our projections, and our estimates prove to be inaccurate, write-downs of inventory values and adjustments to cost of products sold may be required. Property, Plant and Equipment Property, plant and equipment are carried at cost. Depreciation is provided, principally on a straight-line basis, over the estimated useful lives of the assets. Gains or losses resulting from dispositions are included in operating income. Betterments and renewals, which improve and extend the life of an asset, are capitalized; maintenance and repair costs are expensed as incurred. Assets held for use to be disposed of at a future date are depreciated over the remaining useful life. Assets to be sold are written down to fair value less costs to sell at the time the assets are being actively marketed for sale. Estimated useful lives of the related assets are as follows: Buildings and improvements to leaseholds 1 to 40 years Machinery and equipment 1 to 20 years Held for Sale Assets and liabilities to be disposed of by sale ("disposal groups") are reclassified into other current assets and other current liabilities on our consolidated balance sheets. The reclassification occurs when all the held for sale criteria have been met, including when management, having the requisite authority, have committed to a plan to sell the assets within one year. Disposal groups are measured at the lower of carrying value or fair value less costs to sell and are not depreciated or amortized. The fair value of a disposal group, less any costs to sell, is assessed each reporting period it remains classified as held for sale and any remeasurement to the lower of carrying value or fair value less costs to sell is reported as an adjustment to the carrying value. The gain or loss on the sale of assets held for sale are included in non-operating expenses. Long-lived Assets A long-lived asset (including amortizable identifiable intangible assets) or asset group held for use is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Examples of events or circumstances indicating that its carrying amount may not be recoverable include changes in volume, margin, customers and the industry. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate of future cash flows derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value. Fair value is estimated primarily using discounted expected future cash flows on a market-participant basis. Leases Operating lease assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at commencement date. As most of our lease contracts do not provide an explicit interest rate, we use our incremental borrowing rate in determining the present value of future lease payments. Our incremental borrowing rates include estimates related to the impact of collateralization and the economic environment where the leased asset is located. The operating lease assets also include any prepaid lease payments and initial direct costs incurred, but exclude lease incentives received at lease commencement. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Our leases have remaining lease terms of 1 to 10 years, some of which may include options to extend or terminate the lease. Operating lease expense is recognized on a straight-line basis over the lease term. We do not recognize leases with an initial term of twelve months or less on the balance sheet and instead recognize the related lease payments as expense in the consolidated statements of income on a straight-line basis over the lease term. We account for lease and non-lease components as a single lease component for all asset classes. Additionally, for certain equipment leases, we apply a portfolio approach and account for multiple lease components as a single lease component. Certain lease agreements include variable rental payments, including rental payments adjusted periodically for inflation. Variable rental payments are expensed during the period they are incurred and therefore are excluded from our lease assets and liabilities. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Goodwill and Indefinite-lived Intangible Assets We account for goodwill and other intangible assets in accordance with the provisions of ASC 350, Intangibles-Goodwill and Other, and account for business combinations using the acquisition method of accounting and, accordingly, the assets and liabilities of the entities acquired are recorded at their estimated fair values at the acquisition date. Goodwill Goodwill is tested for impairment at least annually in the fourth quarter and written down when impaired. An interim impairment test is performed if an event occurs or conditions change that would more likely than not reduce the fair value of the reporting unit below the carrying value. To evaluate the recoverability of goodwill, we first assess qualitative factors to determine whether it is more likely than not that goodwill is impaired. Qualitative factors include changes in volume, margin, customers and the industry. If it is deemed more likely than not that goodwill for a reporting unit is impaired, we will perform a quantitative impairment test using a weighting of the income and market approaches. We may also elect to bypass the qualitative testing and proceed directly to the quantitative testing. Assessing qualitative factors during 2024, 2023 and 2022 would not have resulted in us performing a quantitative impairment test. In 2024, 2023 and 2022, we elected to bypass the qualitative testing and performed quantitative tests for all goodwill. For the income approach, we use a discounted cash flow model, estimating the future cash flows of the reporting units to which the goodwill relates and then discounting the future cash flows at a market-participant-derived discount rate based on the weighted-average cost of capital. In determining the estimated future cash flows, we consider current and projected future levels of income based on management’s plans for that business; business trends, prospects and market and economic conditions; and market-participant considerations. For the market approach, we apply market multiples for peer groups to the current operating results of the reporting units to determine the reporting unit’s fair value. The Company’s reporting units are operating segments, or one level below operating segments when appropriate. When the estimated fair value of a reporting unit is less than its carrying value, we measure and recognize the amount of the goodwill impairment loss based on that difference. The significant assumptions that are used to determine the estimated fair value for goodwill impairment testing include the following: third-party market forecasts of U.S. new home starts and home repair and remodel spending; management’s sales, operating income and cash flow forecasts; peer company EBITDA earnings multiples; the market-participant-based discount rate; and the perpetuity growth rate. Our estimates of reporting unit fair values are based on certain assumptions that may differ from our historical and future actual operating performance. Specifically, assumptions related to growth in the new construction and repair and remodel segments of the U.S. home products markets drive our forecasted sales growth. The market forecasts are developed using independent third-party forecasts from multiple sources. In addition, estimated future operating income and cash flow consider our historical performance at similar levels of sales volume and management’s future operating plans as reflected in annual and long-term plans that are reviewed and approved by management. As a result of the annual impairment assessments performed for 2024, 2023 and 2022, there were no goodwill impairments. Indefinite-Lived Intangible Assets Certain of our tradenames have been assigned an indefinite life as we currently anticipate that these tradenames will contribute cash flows to the Company indefinitely. Indefinite-lived intangible assets are not amortized, but are evaluated at least annually to determine whether the indefinite useful life is appropriate. We measure the fair value of identifiable intangible assets upon acquisition and we review for impairment annually in the fourth quarter and whenever market or business events indicate there may be a potential impairment of that intangible. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value. The significant assumptions that are used to determine the estimated fair value for indefinite-lived intangible assets upon acquisition and subsequent impairment testing are the market-participant discount rates based on the weighted-average cost of capital; forecasted revenue growth rates; and the assumed royalty rates. The market-participant discount rate used in estimating the fair value of future cash flows is dependent on comparable company prices and other relevant information generated by market transactions, as well as broader market assumptions, such as U.S. treasury rates. Our cash flow projections used to assess impairment of our goodwill and other intangible assets are significantly influenced by our projection for the U.S. home products market, our annual operating plans finalized in the fourth quarter of each fiscal year, and our ability to execute on various planned cost reduction initiatives supporting operating income improvements. Our projection for the U.S. home products market is inherently uncertain and is subject to a number of factors, such as employment, home prices, interest rates, credit availability, new home starts and the rate of home foreclosures. We first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. Qualitative factors include changes in volume, customers and the industry. If it is deemed more likely than not that an intangible asset is impaired, we will perform a quantitative impairment test. We may also elect to bypass the qualitative testing and proceed directly to the quantitative testing. In both 2024 and 2023, we elected to bypass the qualitative testing and tested all of our indefinite-lived tradenames quantitatively. We measure fair value of our indefinite-lived tradenames using the relief-from-royalty approach which estimates the present value of royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. The determination of fair value using this technique requires the use of estimates and assumptions related to forecasted revenue growth rates, the assumed royalty rates and the market-participant discount rates. Events or circumstances that could have a potential negative effect on the estimated fair value of our reporting units and indefinite-lived tradenames include: increases in market-participant discount rates, lower than forecasted revenue growth rates, actual new construction and repair and remodel growth rates that fall below our assumptions, actions of key customers, continued economic uncertainty, higher levels of unemployment, weak consumer confidence, lower levels of discretionary consumer spending, a decrease in assumed royalty rates and a decline in the trading price of our common stock. We cannot predict the occurrence of certain events or changes in circumstances that might adversely affect the carrying value of goodwill and indefinite-lived assets. Business Combinations From time to time, the Company acquires businesses and/or assets that augment and complement our operations. In accordance with ASC 805, “Business Combinations,” these acquisitions are accounted for under the purchase method of accounting. Under this method, the Company allocates the fair value of purchase consideration transferred to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values on the date of the acquisition. The excess purchase consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, is recorded as goodwill. The Company’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. After the measurement period, any subsequent adjustments are reflected in the consolidated statements of income. Acquisition costs, such as legal and consulting fees, are expensed as incurred. The Company classifies costs incurred in connection with acquisitions and their integration as acquisition-related costs. These costs are expensed as incurred and consist primarily of transaction costs, legal and consulting fees, and integration costs and are recorded within selling, general and administrative expenses in the consolidated statements of income . The consolidated financial statements include the results of operations from these business combinations from the date of acquisition. Derivative Financial Instruments In accordance with ASC requirements for derivatives and hedging, we recognize all derivative contracts as either assets or liabilities on the balance sheet, and the measurement of those instruments is at fair value. We account for derivative instruments as follows: • Derivative instruments that are designated as cash flow hedges - The changes in the fair value of the derivative instrument are reported in other comprehensive income and are recognized in the consolidated statements of income when the hedged item affects earnings. In all periods presented, the recognized gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item, are recognized in cost of products sold on the consolidated statements of income. • Derivative instruments that are designated as fair value hedges - The gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item, are recognized in other expense, net on the consolidated statements of income. • Derivative instruments that are designated as net investment hedges - The changes in fair value of the derivative instrument are recognized in the consolidated statements of income when realized upon sale or upon complete or substantially complete liquidation of the investment in the foreign entity. Restructuring Actions Restructuring actions generally include significant actions involving employee-related severance charges, contract termination costs and impairment or accelerated depreciation or amortization of assets associated with such actions. Employee-related severance charges are largely based upon distributed employment policies and substantive severance plans. These charges are reflected in the quarter when the actions are probable and the amounts are estimable, which typically is when management approves the associated actions. Severance amounts for which affected employees in certain circumstances are required to render service in order to receive benefits at their termination dates are measured at the date such benefits are communicated to the applicable employees and recognized as expense over the employees’ remaining service periods. Contract termination and other charges primarily reflect costs to terminate a contract before the end of its term (measured at fair value at the time the Company provided notice to the counterparty) or costs that will continue to be incurred under the contract for its remaining term without economic benefit to the Company. Pension and Postretirement Benefits Other than Pensions We have a pension plan in the United States covering many of the Company’s associates. However, the plan has been frozen to new participants and benefit accruals were frozen for active participants on or before December 31, 2016. During 2023, the Board of Directors of MasterBrand, Inc. approved a plan to terminate the defined benefit pension plan. The termination and settlement process, which preserves retirement benefits due to participants but changes the ultimate payor of such benefits, is expected to take up to 24 months to complete, subject to receipt of customary regulatory approvals. During 2025, we expect to complete the purchase of group annuity contracts that will transfer any remaining pension benefit obligation to an insurance company. In addition, the Company provides postretirement health care and life insurance benefits to certain retirees. We record amounts relating to these plans based on calculations in accordance with ASC requirements for Compensation—Retirement Benefits, which include various actuarial assumptions, including discount rates, assumed rates of return, turnover and mortality rates and health care cost trend rates. Actuarial gains or losses related to these assumptions represent the difference between actual and actuarially assumed experience. We recognize changes in the fair value of pension plan assets and net actuarial gains or losses in other expense, net to the extent they are in excess of 10 percent of the greater of the fair value of pension plan assets or the plan’s projected benefit obligation (the “corridor”) in earnings immediately upon remeasurement, which is at least annually in the fourth quarter of each fiscal year. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. The discount rate used to measure obligations is based on a spot-rate yield curve on a plan-by-plan basis that matches projected future benefit payments with the appropriate interest rate applicable to the timing of the projected future benefit payments. The expected rate of return on plan assets is determined based on the nature of the plans’ investments, our current asset allocation and our expectations for long-term rates of return. For postretirement benefits, our health care trend rate assumptions are based on historical cost increases and expectations for long-term increases. The cost or benefit of plan changes, such as increasing or decreasing benefits for prior associate service (prior service cost), is deferred and included in expense on a straight-line basis over the average remaining service period of the related associates. We believe that the assumptions utilized in recording obligations under our plans, which are presented in Note 15, "Pension and Other Postretirement Plans," are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial position and results of operations. We will continue to monitor these assumptions as market conditions warrant. Insurance Reserves We provide for expenses associated with workers’ compensation and product liability obligations when such amounts are probable and can be reasonably estimated. The accruals are adjusted as new information develops or circumstances change that would affect the estimated liability. Litigation Contingencies Our |
