Accounting Policies [Abstract] |
BASIS OF PRESENTATION | BASIS OF PRESENTATION — The Consolidated Financial Statements include the accounts of Stanley Black & Decker, Inc. and its majority-owned subsidiaries (collectively the “Company”) which require consolidation, after the elimination of intercompany accounts and transactions. The Company’s fiscal year ends on the Saturday nearest to December 31. There were 52 weeks in fiscal year 2021, 53 weeks in the fiscal years 2020, and 52 weeks in fiscal year 2019. In December 2021, the Company acquired the remaining 80 percent ownership stake in MTD Holdings Inc. ("MTD"), a privately held global manufacturer of outdoor power equipment. The Company previously acquired a 20 percent interest in MTD in January 2019. Prior to closing on the remaining 80 percent ownership stake, the Company applied the equity method of accounting to the 20% investment in MTD. In November 2021, the Company acquired Excel Industries ("Excel"), a leading designer and manufacturer of premium commercial and residential turf-care equipment. These acquisitions are being accounted for as business combinations using the acquisition method of accounting and the results subsequent to the dates of acquisition are included in the Company's Tools & Storage segment. In February 2020, the Company acquired Consolidated Aerospace Manufacturing, LLC ("CAM"). In March 2019, the Company acquired International Equipment Solutions Attachments businesses, Paladin and Pengo, ("IES Attachments"). The 2020 and 2019 acquisitions were accounted for as business combinations using the acquisition method of accounting and the results subsequent to the respective dates of acquisition are included in the Company's Industrial segment. Refer to Note E, Acquisitions and Investments, for further discussion on these transactions. In December 2021, upon announcing it reached a definitive agreement for the sale of most of its Security assets, the Company classified the Convergent Security Solutions ("CSS") business as held for sale on the Company's Consolidated Balance Sheets as of January 1, 2022 and January 2, 2021. The operating results of CSS have been reported as discontinued operations in the Consolidated Financial Statements. Amounts previously reported have been reclassified to conform to this presentation in accordance with Accounting Standard Codification ("ASC") 205, Presentation of Financial Statements ("ASC 205"), to allow for meaningful comparison of continuing operations. In November 2020, the Company sold its commercial electronic operations in five countries in Europe and emerging markets within the Security segment. In October 2020, the Company sold a product line in Oil & Gas within the Industrial segment. The operating results of these businesses have been reported in the Consolidated Financial Statements through the dates of sale in 2020 and for the year ended December 28, 2019. In May 2019, the Company sold its Sargent & Greenleaf mechanical locks business within the Security segment. The operating results of this business have been reported in the Consolidated Financial Statements through the date of sale in 2019. Refer to Note T, Divestitures, for further discussion on these transactions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements. While management believes that the estimates and assumptions used in the preparation of the financial statements are appropriate, actual results could differ from these estimates. Certain amounts reported in previous years have been reclassified to conform to the 2021 presentation.
FOREIGN CURRENCY | FOREIGN CURRENCY — For foreign operations with functional currencies other than the U.S. dollar, asset and liability accounts are translated at current exchange rates, while income and expenses are translated using average exchange rates. Translation adjustments are reported in a separate component of shareowners’ equity and exchange gains and losses on transactions are included in earnings.
CASH EQUIVALENTS | CASH EQUIVALENTS — Highly liquid investments with original maturities of three months or less are considered cash equivalents.
ACCOUNTS AND FINANCING RECEIVABLE | ACCOUNTS AND FINANCING RECEIVABLE — Trade receivables are stated at gross invoice amounts less discounts, other allowances and provisions for credit losses. Financing receivables are initially recorded at fair value, less impairments or provisions for credit losses. Interest income earned from financing receivables that are not delinquent is recorded on the effective interest method. The Company considers any financing receivable that has not been collected within 90 days of original billing date as past-due or delinquent. The Company's payment terms are generally consistent with the industries in which its businesses operate and typically range from 30-90 days globally. Additionally, the Company considers the credit quality of all past-due or delinquent financing receivables as nonperforming. The Company does not adjust the promised amount of consideration for the effects of a significant financing component when the period between transfer of the product and receipt of payment is less than one year. Any significant financing components for contracts greater than one year are included in revenue over time.
ALLOWANCE FOR CREDIT LOSSES | ALLOWANCE FOR CREDIT LOSSES — The Company maintains an allowance for credit losses, which represents an estimate of expected losses over the remaining contractual life of its receivables. The allowance is determined using two methods. The amounts calculated from each of these methods are combined to determine the total amount reserved. First, a specific reserve is established for individual accounts where information indicates the customers may have an inability to meet financial obligations. Second, a reserve is determined for all customers based on a range of percentages applied to aging categories. These percentages are based on historical collection rates, write-off experience, and forecasts of future economic conditions. Actual write-offs are charged against the allowance when collection efforts have been unsuccessful.
INVENTORIES | INVENTORIES — U.S. inventories are primarily valued at the lower of Last-In First-Out (“LIFO”) cost or market because the Company believes it results in better matching of costs and revenues. Other inventories are primarily valued at the lower of First-In, First-Out (“FIFO”) cost and net realizable value because LIFO is not permitted for statutory reporting outside the U.S. Refer to Note C, Inventories, for a quantification of the LIFO impact on inventory valuation.
PROPERTY, PLANT AND EQUIPMENT | PROPERTY, PLANT AND EQUIPMENT — The Company generally values property, plant and equipment (“PP&E”), including capitalized software, at historical cost less accumulated depreciation and amortization. Costs related to maintenance and repairs which do not prolong the asset's useful life are expensed as incurred. Depreciation and amortization are provided using straight-line methods over the estimated useful lives of the assets as follows:
|  | Useful Life (Years)
Land improvements |  | 10 — 20
Buildings |  | 40
Machinery and equipment |  | 3 — 15
Computer software |  | 3 — 7
Leasehold improvements are depreciated over the shorter of the estimated useful life or the term of the lease. The Company reports depreciation and amortization of property, plant and equipment in cost of sales and selling, general and administrative expenses based on the nature of the underlying assets. Depreciation and amortization related to the production of inventory and delivery of services are recorded in cost of sales. Depreciation and amortization related to distribution center activities, selling and support functions are reported in selling, general and administrative expenses. The Company assesses its long-lived assets for impairment when indicators that the carrying amounts may not be recoverable are present. In assessing long-lived assets for impairment, the Company groups its long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are generated (“asset group”) and estimates the undiscounted future cash flows that are directly associated with, and expected to be generated from, the use of and eventual disposition of the asset group. If the carrying value is greater than the undiscounted cash flows, an impairment loss must be determined and the asset group is written down to fair value. The impairment loss is quantified by comparing the carrying amount of the asset group to the estimated fair value, which is generally determined using weighted-average discounted cash flows that consider various possible outcomes for the disposition of the asset group.
GOODWILL AND INTANGIBLE ASSETS | GOODWILL AND INTANGIBLE ASSETS — Goodwill represents costs in excess of values assigned to the underlying net assets of acquired businesses. Intangible assets acquired are recorded at estimated fair value. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are tested for impairment annually during the third quarter, and at any time when events suggest an impairment more likely than not has occurred. To assess goodwill for impairment, the Company, depending on relevant facts and circumstances, performs either a qualitative assessment or a quantitative analysis utilizing a discounted cash flow valuation model. In performing a qualitative assessment, the Company first assesses relevant factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test. The Company identifies and considers the significance of relevant key factors, events, and circumstances that could affect the fair value of each reporting unit. These factors include external factors such as macroeconomic, industry, and market conditions, as well as entity-specific factors, such as actual and planned financial performance. The Company also considers changes in each reporting unit's fair value and carrying amount since the most recent date a fair value measurement was performed. In performing a quantitative analysis, the Company determines the fair value of a reporting unit using management’s assumptions about future cash flows based on long-range strategic plans. This approach incorporates many assumptions including discount rates, future growth rates and expected profitability. In the event the carrying amount of a reporting unit exceeded its fair value, an impairment loss would be recognized. Indefinite-lived intangible assets are tested for impairment utilizing either a qualitative assessment or a quantitative analysis. For a qualitative assessment, the Company identifies and considers relevant key factors, events, and circumstances to determine whether it is necessary to perform a quantitative impairment test. The key factors considered include macroeconomic, industry, and market conditions, as well as the asset's actual and forecasted results. For the quantitative impairment tests, the Company compares the carrying amounts to the current fair market values, usually determined by the estimated royalty savings attributable to owning the intangible assets. Intangible assets with definite lives are amortized over their estimated useful lives to reflect the pattern over which the economic benefits of the intangible assets are consumed. Definite-lived intangible assets are also evaluated for impairment when impairment indicators are present. If the carrying amount exceeds the total undiscounted future cash flows, a discounted cash flow analysis is performed to determine the fair value of the asset. If the carrying amount of the asset was to exceed the fair value, it would be written down to fair value. No significant goodwill or other intangible asset impairments were recorded during 2021, 2020 or 2019.
FINANCIAL INSTRUMENTS | FINANCIAL INSTRUMENTS — Derivative financial instruments are employed to manage risks, including foreign currency, interest rate exposures and commodity prices and are not used for trading or speculative purposes. As part of the Company’s risk management program, a variety of financial instruments such as interest rate swaps, currency swaps, purchased currency options, foreign exchange contracts and commodity contracts, may be used to mitigate interest rate exposure, foreign currency exposure and commodity price exposure. The Company recognizes all derivative instruments on the balance sheet at fair value. Changes in the fair value of derivatives are recognized periodically either in earnings or in shareowners’ equity as a component of other comprehensive income (loss) ("OCI"), depending on whether the derivative financial instrument is undesignated or qualifies for hedge accounting, and if so, whether it represents a fair value, cash flow, or net investment hedge. Changes in the fair value of derivatives accounted for as fair value hedges are recorded in earnings in the same caption as the changes in the fair value of the hedged items. Gains and losses on derivatives designated as cash flow hedges, to the extent they are included in the assessment of effectiveness, are recorded in OCI and subsequently reclassified to earnings to offset the impact of the hedged items when they occur. In the event it becomes probable the forecasted transaction to which a cash flow hedge relates will not occur, the derivative would be terminated and the amount in accumulated other comprehensive income (loss) would be recognized in earnings. Changes in the fair value of derivatives that are designated and qualify as a hedge of the net investment in foreign operations, to the extent they are included in the assessment of effectiveness, are reported in OCI and are deferred until disposal of the underlying assets. Gains and losses representing components excluded from the assessment of effectiveness for cash flow and fair value hedges are recognized in earnings on a straight-line basis in the same caption as the hedged item over the term of the hedge. Gains and losses representing components excluded from the assessment of effectiveness for net investment hedges are recognized in earnings on a straight-line basis in Other, net over the term of the hedge. The net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining period of the debt originally covered by the terminated swap. Changes in the fair value of derivatives not designated as hedges are reported in Other, net in the Consolidated Statements of Operations. Refer to Note I, Financial Instruments, for further discussion.
REVENUE RECOGNITION | REVENUE RECOGNITION — The Company’s revenues result from the sale of goods or services and reflect the consideration to which the Company expects to be entitled. The Company records revenue based on a five-step model in accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"). For its contracts with customers, the Company identifies the performance obligations (goods or services), determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) the performance obligation is transferred to the customer. A good or service is transferred when (or as) the customer obtains control of that good or service. The majority of the Company’s revenues are recorded at a point in time from the sale of tangible products. A portion of the Company’s revenues within the CSS and Infrastructure businesses is generated from equipment leased to custome rs. Customer arrangements are identified as leases if they include transfer of a tangible asset which is provided to the customer in exchange for payments typically at fixed rates payable monthly, quarterly or annually. Customer leases may include terms to allow for extension of leases for a short period of time, but typically do not provide for customer termination prior to the initial term. Some customer leases include terms to allow the customer to purchase the underlying asset, which occurs occasionally, and virtually no customer leases include residual value guarantee clauses. Within the CSS business, the underlying asset typically has no value at termination of the customer lease, so no residual value asset is recorded in the financial statements. For Infrastructure business leases, underlying assets are assessed for functionality at termination of the lease and, if necessary, an impairment to the leased asset value is recorded. Provisions for customer volume rebates, product returns, discounts and allowances are variable consideration and are recorded as a reduction of revenue in the same period the related sales are recorded. Such provisions are calculated using historical averages adjusted for any expected changes due to current business conditions. Consideration given to customers for cooperative advertising is recognized as a reduction of revenue except to the extent that there is a distinct good or service and evidence of the fair value of the advertising, in which case the expense is classified as selling, general, and administrative expense. The Company’s revenues can be generated from contracts with multiple performance obligations. When a contract involves multiple performance obligations, each obligation is separately identified and the transaction price is allocated based on the amount of consideration the Company expects to be entitled to in exchange for transferring the promised good or service to the customer. Sales of security monitoring systems, within the CSS business, may have multiple performance obligations, including equipment, installation and monitoring or maintenance services. In most instances, the Company allocates the appropriate amount of consideration to each performance obligation based on the standalone selling price ("SSP") of the distinct goods or services performance obligation. In circumstances where SSP is not observable, the Company allocates the consideration for the performance obligations by utilizing one of the following methods: expected cost plus margin, the residual approach, or a mix of these estimation methods. For performance obligations that the Company satisfies over time, revenue is recognized by consistently applying a method of measuring progress toward complete satisfaction of that performance obligation. The Company utilizes the method that most accurately depicts the progress toward completion of the performance obligation. The Company’s contract sales for the installation of security intruder systems and other construction-related projects, within the CSS busines s, are generally recorded under the input method. The input method recognizes revenue on the basis of the Company’s efforts or inputs to the satisfaction of a performance obligation relative to the total inputs expected to satisfy that performance obligation. Revenue recognized on security contracts in process are based upon the allocated contract price and related total inputs of the project at completion. The extent of progress toward completion is generally measured using input methods based on labor metrics. Revisions to these estimates as contracts progress have the effect of increasing or decreasing profits each period. Provisions for anticipated losses are made in the period in which they become determinable. The revenues for monitoring and monitoring-related services are recognized as services are rendered over the contractual period. The Company utilizes the output method for contract sales in the Oil & Gas product line. The output method recognizes revenue based on direct measurements of the customer value of the goods or services transferred to date relative to the remaining goods or services promised under the contract. The output method includes methods such as surveys of performance completed to date, appraisals of results achieved, milestones reached, time elapsed, and units produced or units delivered. Contract assets or liabilities result from transactions with revenue recorded over time. If the measure of remaining rights exceeds the measure of the remaining performance obligations, the Company records a contract asset. Conversely, if the measure of the remaining performance obligations exceeds the measure of the remaining rights, the Company records a contract liability. Incremental costs of obtaining or fulfilling a contract with a customer that are expected to be recovered are recognized and classified in Other current assets or Other assets in the Consolidated Balance Sheets and are typically amortized over the contract period. The Company recognizes the incremental costs of obtaining or fulfilling a contract as expense when incurred if the amortization period of the asset is one year or less. Customer billings for services not yet rendered are deferred and recognized as revenue as the services are rendered. The associated deferred revenue is included in Accrued expenses or Other liabilities, as appropriate, in the Consolidated Balance Sheets.
COST OF SALES AND SELLING, GENERAL & ADMINISTRATIVE | COST OF SALES AND SELLING, GENERAL & ADMINISTRATIVE — Cost of sales includes the cost of products and services provided, reflecting costs of manufacturing and preparing the product for sale. These costs include expenses to acquire and manufacture products to the point that they are allocable to be sold to customers and costs to perform services pertaining to service revenues (e.g. installation of security systems, automatic doors, and security monitoring costs). Cost of sales is primarily comprised of freight, direct materials, direct labor as well as overhead which includes indirect labor and facility and equipment costs. Cost of sales also includes quality control, procurement and material receiving costs as well as internal transfer costs. Selling, general & administrative costs ("SG&A") include the cost of selling products as well as administrative function costs. These expenses generally represent the cost of selling and distributing the products once they are available for sale and primarily include salaries and commissions of the Company’s sales force, distribution costs, notably salaries and facility costs, as well as administrative expenses for certain support functions and related overhead.
ADVERTISING COSTS | ADVERTISING COSTS — Television advertising is expensed the first time the advertisement airs, whereas other advertising is expensed as incurred.
SALES TAXES | SALES TAXES — Sales and value added taxes collected from customers and remitted to governmental authorities are excluded from Net Sales reported in the Consolidated Statements of Operations.
SHIPPING AND HANDLING COSTS | SHIPPING AND HANDLING COSTS — The Company generally does not bill customers for freight. Shipping and handling costs associated with inbound and outbound freight are reported in Cost of sales.
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION — Compensation cost relating to stock-based compensation grants is recognized on a straight-line basis over the vesting period, which is generally four years. The expense for stock options and restricted stock units awarded to retirement-eligible employees (those aged 55 and over, and with 10 or more years of service) is recognized on the grant date, or (if later) by the date they become retirement-eligible.
POSTRETIREMENT DEFINED BENEFIT PLAN | POSTRETIREMENT DEFINED BENEFIT PLAN — The Company uses the corridor approach to determine expense recognition for each defined benefit pension and other postretirement plan. The corridor approach defers actuarial gains and losses resulting from variances between actual and expected results (based on economic estimates or actuarial assumptions) and amortizes them over future periods. For pension plans, these unrecognized gains and losses are amortized when the net gains and losses exceed 10% of the greater of the market-related value of plan assets or the projected benefit obligation at the beginning of the year. For other postretirement benefits, amortization occurs when the net gains and losses exceed 10% of the accumulated postretirement benefit obligation at the beginning of the year. For ongoing, active plans, the amount in excess of the corridor is amortized on a straight-line basis over the average remaining service period for active plan participants. For plans with primarily inactive participants, the amount in excess of the corridor is amortized on a straight-line basis over the average remaining life expectancy of inactive plan participants.
INCOME TAXES | INCOME TAXES — The Company accounts for income taxes under the asset and liability method in accordance with ASC 740, Income Taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to reverse. Any changes in tax rates on deferred tax assets and liabilities are recognized in earnings in the period that includes the enactment date. The Company recognizes the tax on global intangible low-taxed income as a period expense in the period the tax is incurred. The Company records net deferred tax assets to the extent that it is more likely than not that these assets will be realized. In making this determination, management considers all available positive and negative evidence, including future reversals of existing temporary differences, estimates of future taxable income, tax-planning strategies, and the realizability of net operating loss carryforwards. In the event that it is determined that an asset is not more likely that not to be realized, a valuation allowance is recorded against the asset. Valuation allowances related to deferred tax assets can be impacted by changes to tax laws, changes to statutory tax rates and future taxable income levels. In the event the Company were to determine that it would not be able to realize all or a portion of its deferred tax assets in the future, the unrealizable amount would be charged to earnings in the period in which that determination is made. Conversely, if the Company were to determine that it would be able to realize deferred tax assets in the future in excess of the net carrying amounts, it would decrease the recorded valuation allowance through a favorable adjustment to earnings in the period that the determination was made. The Company records uncertain tax positions in accordance with ASC 740, which requires a two-step process. First, management determines whether it is more likely than not that a tax position will be sustained based on the technical merits of the position and second, for those tax positions that meet the more likely than not threshold, management recognizes the largest amount of the tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related taxing authority. The Company maintains an accounting policy of recording interest and penalties on uncertain tax positions as a component of Income taxes in the Consolidated Statements of Operations. The Company is subject to income tax in a number of locations, including many state and foreign jurisdictions. Significant judgment is required when calculating the worldwide provision for income taxes. Many factors are considered when evaluating and estimating the Company's tax positions and tax benefits, which may require periodic adjustments, and which may not accurately anticipate actual outcomes. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company's unrecognized tax positions will significantly increase or decrease within the next twelve months. These changes may be the result of settlements of ongoing audits, litigation, or other proceedings with taxing authorities. The Company periodically assesses its liabilities and contingencies for all tax years still subject to audit based on the most current available information, which involves inherent uncertainty.
EARNINGS PER SHARE | EARNINGS PER SHARE — Basic earnings per share equals net earnings attributable to common shareowners divided by weighted-average shares outstanding during the year. Diluted earnings per share include the impact of common stock equivalents using the treasury stock method or the if-converted method, as applicable, when the effect is dilutive.
NEW AND RECENTLY ADOPTED ACCOUNTING STANDARDS | NEW ACCOUNTING STANDARDS ADOPTED — In January 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The new standard clarifies the interaction of accounting for the transition into and out of the equity method. The new standard also clarifies the accounting for measuring certain purchased options and forward contracts to acquire investments. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted this guidance in the first quarter of 2021 and it did not have a material impact on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740). The new standard simplifies the accounting for income taxes by removing certain exceptions for recognizing deferred taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. The new standard also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted this standard in the first quarter of 2021 and it did not have a material impact on the Company’s consolidated financial statements. RECENTLY ISSUED ACCOUNTING STANDARDS NOT YET ADOPTED — In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new standard improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency. The new standard requires an entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The standard should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company will adopt this guidance in the first quarter of 2022 and does not expect it to have a material impact on its consolidated financial statements. In May 2021, the FASB issued ASU 2021-04, Earnings per share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Equity (Subtopic 815-40). The new standard clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The ASU is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The standard should be applied prospectively. The Company will adopt this guidance in the first quarter of 2022 and does not expect it to have a material impact on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). The new standard reduces the number of accounting models for convertible debt instruments and convertible preferred stock, and amends the guidance for the derivatives scope exception for contracts in an entity's own equity. The standard also amends and makes targeted improvements to the related earnings per share guidance. The ASU is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The standard allows for either modified or full retrospective transition methods. The Company will adopt this guidance in the first quarter of 2022. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new standard provides optional expedients and exceptions that companies can apply during a limited time period to account for contracts, hedging relationships, and other transactions affected by reference rate reform, if certain criteria are met. Companies may elect to apply these optional expedients and exceptions beginning March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848), to clarify the scope of Topic 848 and provide explicit guidance to help companies applying optional expedients and exceptions. This ASU is effective immediately for all entities that have applied optional expedients and exceptions. The Company plans to apply certain optional expedients and exceptions as needed to comply with regulatory and tax authorities for the transition to alternative reference rates. The Company does not expect adoption to have a material impact to its consolidated financial statements.
