Accounting Policies [Abstract]
Description of the Business, Basis of Presentation and Summary of Significant Accounting Policies	Description of the Business, Basis of Presentation and Summary of Significant Accounting Policies Fox Factory Holding Corp. (the "Company") designs, engineers, manufactures and markets performance-defining products and systems for customers worldwide. Our premium brand, performance-defining products and systems are used primarily for bicycles ("bikes"), side-by-side vehicles ("side-by-sides"), on-road vehicles with and without off-road capabilities, off-road vehicles and trucks, all-terrain vehicles ("ATVs"), snowmobiles, specialty vehicles and applications, motorcycles and commercial trucks. Some of our products are specifically designed and marketed to the leading cycling and powered vehicle original equipment manufacturers ("OEMs"), while others are distributed to consumers through a global network of dealers and distributors. Throughout this Annual Report on Form 10-K, unless stated otherwise or as the context otherwise requires, the "Company," "FOX," "Fox Factory," "we," "us," "our," and "ours" refer to Fox Factory Holding Corp. and its operating subsidiaries on a consolidated basis. Basis of Presentation - The accompanying consolidated financial statements have been prepared in accordance with United States of America ("U.S.") generally accepted accounting principles ("GAAP"). Fiscal Year Calendar - The Company operates using a 52-53 week fiscal year calendar ending on the Friday nearest to December 31. Therefore, the financial results of certain fiscal years and quarters, which will contain 53 and 14 weeks, respectively, will not be exactly comparable to the prior and subsequent fiscal years and quarters, which contain 52 and 13 weeks, respectively. For the fiscal years 2021, 2020 and 2019, the Company's fiscal year ended on December 31, 2021, January 1, 2021 and January 3, 2020 and had 52, 52 and 53 weeks, respectively. Principles of Consolidation - The consolidated financial statements include the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates - The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management’s estimates. Foreign Currency Translation and Transaction - The functional currency of the Company’s non-U.S. entities is the local currency of the respective operations. The Company translates the financial statements of its non-U.S. entities into U.S. Dollars each reporting period for purposes of consolidation. Assets and liabilities of the Company’s foreign subsidiaries are translated at the period-end currency exchange rates while sales and expenses are translated at the average currency exchange rates in effect for the period. The effects of these translation adjustments are a component of other comprehensive income. Foreign currency transaction losses of $455, $396, and $881 for the years ended December 31, 2021, January 1, 2021 and January 3, 2020, respectively, are included as a component of other income or expense. Cash and Cash Equivalents - Cash consists of cash maintained in checking or money market accounts. All highly liquid investments purchased with an original maturity date of 90 days or less at the date of purchase are considered to be cash equivalents. Accounts Receivable - Accounts receivable are unsecured customer obligations which generally require payment within various terms from the invoice date. The receivables are stated at the invoice amount. Financing terms vary by customer. Invoices are considered past due when payment is not received within the terms stated within the contract. Payments of accounts receivable are applied to the specific invoices identified on the customer’s remittance advice or if unspecified, generally to the earliest unpaid invoices. The carrying amount of accounts receivable is reduced by a valuation allowance that reflects management’s best estimate of amounts that may not be collected. All accounts or portions thereof deemed to be uncollectible or that may require an excessive collection cost are written off to the allowance for credit losses. Concentration of Credit Risk - Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and accounts receivable. As of December 31, 2021 the Company held $135,142 in cash at U.S. subsidiaries and $44,544 at subsidiaries outside the U.S. The account balances may significantly exceed the insurance coverage provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company has not experienced any losses in its uninsured accounts. The Company mitigates its credit risk with respect to accounts receivable by performing ongoing credit evaluations and monitoring of its customers’ accounts receivable balances. The following customers accounted for 10% or more of the Company's accounts receivable balance: December 31, January 1, 2021 2021 Customer A 11% 12% Customer B 10% 11% No other customers were individually significant in any of these periods presented. The Company depends on a limited number of vendors to supply component parts for its products. The Company purchased 32%, 28%, and 35% of its product components for the years ended December 31, 2021, January 1, 2021 and January 3, 2020, respectively, from ten vendors. As of December 31, 2021 and January 1, 2021, amounts due to these vendors represented 10% and 17% of accounts payable, respectively. Allowance for Credit Losses - The Company records a provision for credit losses based on historical experience and a detailed assessment of the collectability of its accounts receivable. The provision is based on how long a receivable has been outstanding, taking into account the historical credit loss rate and adjusting for both current conditions and forecasts of economic conditions into that expected credit loss rate. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer’s ability to meet its financial obligations, the Company’s estimate of the recoverability of the amounts due could be reduced by a material amount. The following table presents the activity in the allowance for credit losses: For the fiscal years ended Allowance for credit losses: 2021 2020 2019 Balance, beginning of year $ 663 $ 810 $ 600 Add: bad debt (benefit) expense (14) 103 335 Less: write-offs, net of recoveries (239) (250) (125) Balance, end of year $ 410 $ 663 $ 810 Inventories - Inventories are stated at the lower of actual cost (or standard cost which generally approximates actual costs on a first-in first-out basis) or net realizable value. Cost includes raw materials and inbound freight, as well as direct labor and manufacturing overhead for products we manufacture. Net realizable value is based on current replacement cost for raw materials and on a net realizable value for finished goods. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolescence or impaired balances. Property and Equipment - Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. Leasehold improvements are amortized on a straight-line basis over the terms of the lease, or the useful lives of the assets, whichever is shorter. The value assigned to land associated with buildings we own is not amortized. Depreciation and amortization periods for the Company’s property and equipment are as follows: Asset Classification Estimated useful life Building and building improvements 15-39 years Information systems, office equipment and furniture 3-7 years Internal-use computer software 10 years Land improvements 15 years Machinery and manufacturing equipment 5-15 years Transportation equipment 3-5 years Internal-use Computer Software Costs - Costs incurred to purchase and develop computer software for internal use are capitalized during the application development and implementation stages. These software costs have been for enterprise-level business and finance software that is customized to meet the Company’s operational needs. Capitalized costs are included in property and equipment and are amortized on a straight-line basis over the estimated useful life of the software beginning when the software project is substantially complete and placed in service. The Company capitalized $5,847 in internal use computer software costs during the year ended December 31, 2021. Costs incurred during the preliminary project stage and costs for training, data conversion, and maintenance are expensed as incurred. Impairment of Long-lived Assets - The Company periodically reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the assets, an impairment loss is recorded to write the assets down to their estimated fair values. Fair value is estimated based on discounted future cash flows. No impairment charges were recorded during the years ended December 31, 2021, January 1, 2021 and January 3, 2020. Business Combinations - The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. The Company allocates the purchase price of the acquisition to the tangible assets acquired, liabilities assumed and identifiable intangible assets acquired based on their estimated fair values. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred. During the measurement period, the Company records adjustments to provisional amounts recorded for assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could be up to one year after the transaction date, subsequent adjustments are recorded to the Company’s consolidated statements of income. Goodwill and Intangible Assets - Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis, the Company makes a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. We completed our most recent annual impairment test in the third quarter of 2021 at which time we had a single reporting unit for purposes of assessing goodwill impairment. No impairment charges have been incurred to date. Intangible assets including customer relationships, certain trademarks, and the Company’s core technology, are subject to amortization over their respective useful lives, and are classified in intangibles, net in the accompanying consolidated balance sheet. These intangibles are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be fully recoverable. If facts and circumstances indicate that the carrying value might not be recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives is compared against their respective carrying amounts. If an asset is found to be impaired, the impairment charge will be measured as the amount by which the carrying amount of an entity exceeds its fair value. Certain trademarks and brands are considered to be indefinite life intangibles, and are not amortized but are subject to testing for impairment annually. No impairments of intangible assets were identified in the years ended December 31, 2021, January 1, 2021 and January 3, 2020. Self-Insurance - The Company is partially self-insured for its U.S. employee health and welfare benefits. The Company’s liability for self-insurance is based on claims filed and an estimate of claims incurred but not yet reported. The Company considers a number of factors, including historical claims information, when determining the amount of the accrual. Costs related to the administration of the plan and related claims are expensed as incurred. The Company has third-party insurance coverage to limit exposure for individually significant claims. The estimates for unpaid claims incurred as of December 31, 2021 and January 1, 2021 are $1,754 and $1,472 respectively, and are recorded within accrued expenses on the consolidated balance sheets. Revenue Recognition - Revenues are generated from the sale of performance-defining products and systems to customers worldwide. The Company’s performance-defining products and systems are solutions that improve performance of powered vehicles and bikes. Powered vehicles include side-by-sides, on-road vehicles with off-road capabilities, off-road vehicles and trucks, ATVs, snowmobiles, specialty vehicles and applications, and motorcycles. Revenue is measured based on the consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer, generally at the time of shipment. Contracts are generally in the form of purchase orders and are governed by standard terms and conditions. For larger OEMs, the Company may also enter into master agreements. Sales tax and other similar taxes are excluded from revenues. Provisions for discounts, rebates, sales incentives, returns, and other adjustments are generally provided for in the period the related sales are recorded, based on management’s assessment of historical trends and projection of future results. Certain pricing provisions that provide the customer with future discounts are considered a material right. Such material rights result in the deferral of revenues that are recognized when the rights are exercised by the customer. Measuring the material rights requires judgments including forecasts of future sales and product mix. Cost of Sales - Cost of sales primarily consists of materials and labor expense in the manufacturing of the Company’s products sold to customers. Cost of sales also includes provisions for excess and obsolete inventory, warranty costs, certain allocated costs for facilities, depreciation and other manufacturing overhead. Additionally, it includes stock-based compensation for personnel directly involved with manufacturing the Company’s product offerings. Shipping and Handling Fees and Costs - The Company includes shipping and handling fees billed to customers in sales. Shipping costs associated with inbound freight are capitalized as part of inventory and included in cost of sales as products are sold. Sales and Marketing - Sales and marketing expenses include costs related to sales, customer service and marketing personnel, including their wages, employee benefits and related stock-based compensation, and occupancy related expenses. Other significant sales and marketing expenses include race support and sponsorships of events and athletes, advertising and promotions related to trade shows, travel and entertainment, and promotional materials, products and sales offices costs. Research and Development - Research and development expenses consist primarily of salaries and personnel costs, including wages, employee benefits and related stock-based compensation for the Company’s engineering, research and development teams, occupancy related expenses, fees for third party consultants, service fees, and expenses for prototype tooling and materials, travel, and supplies. The Company expenses research and development costs as incurred. General and Administrative - General and administrative expenses include costs related to executive, finance, information technology, human resources and administrative personnel, including wages, employee benefits and related stock-based compensation expenses. The Company records professional and contract service expenses, occupancy related expenses associated with corporate locations and equipment, and legal expenses in general and administrative expenses. Stock-Based Compensation - The Company measures stock-based compensation for all stock-based awards, including stock options and restricted stock units (“RSUs”), based on their estimated fair values on the date of the grant and recognizes the stock-based compensation cost for time-vested awards on a straight-line basis over the requisite service period. For performance-based RSUs, the number of shares ultimately expected to vest is estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. To the extent shares are expected to vest, the stock-based compensation cost is recognized on a straight-line basis over the requisite service period. The fair value of each stock option granted is estimated using the Black-Scholes option-pricing model. The Company does not estimate forfeitures in recognizing stock-based compensation expense. The fair value of the RSUs is equal to the fair value of the Company’s common stock on the grant date of the award. Income Taxes - Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Operating loss and tax credit carryforwards are measured by applying currently enacted tax laws. Valuation allowances are provided when necessary to reduce net deferred tax assets to an amount that is more likely than not to be realized. The Company has elected to account for global intangible low-taxed income ("GILTI") in the year the tax is incurred, rather than recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years. The net GILTI inclusion for the year ended December 31, 2021 was fully offset by foreign tax credits associated with the income. The Company recognizes the tax effects of an uncertain tax position only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date and then only in an amount more likely than not to be sustained upon review by the tax authorities. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Advertising - Advertising costs are expensed as incurred and recorded as sales and marketing expenses on our Consolidated Statements of Income. Costs incurred for advertising totaled $2,741, $2,188, and $1,413 for the years ended December 31, 2021, January 1, 2021 and January 3, 2020, respectively. Warranties - The Company offers limited warranties on its products generally for one Segments - The Company has determined that it has a single operating and reportable segment; manufacturing, sale and service of performance-defining products. The Company considers operating segments to be components of the Company in which separate financial information is available that is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker for the Company is the Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Fair Value Measurements and Financial Instruments - The Financial Accounting Standards Board ("FASB") has issued Accounting Standards Codification 820, Fair Value Measurements and Disclosures , that requires the valuation of assets and liabilities required or permitted to be either recorded or disclosed at fair value based on hierarchy of available inputs as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The carrying amounts of the Company’s financial instruments, including cash, receivables, accounts payable, and accrued liabilities approximate their fair values due to their short-term nature. Amounts owed under the Company's credit facility approximate fair value due to the variable interest rate features embedded in both the line of credit and term debt. Certain Significant Risks and Uncertainties - The Company is subject to those risks common in manufacturing-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. Additionally, the Company has been impacted by the coronavirus (“COVID-19”) outbreak. The global outbreak of COVID-19 has negatively affected the U.S. and global economy, disrupted global supply chains, resulted in significant travel and transport restrictions, including mandated closures and orders to “shelter-in-place,” and created significant disruption of the financial markets. Despite the Company’s efforts to manage and remedy these impacts to the Company, the ultimate impact and the extent to which the COVID-19 pandemic will continue to affect the business, results of operation and financial condition is difficult to predict and depends on numerous evolving factors outside of the Company’s control including: the duration and scope of the pandemic; government, social, business and other actions that have been and will be taken in response to the pandemic; and the effect of the pandemic on short and long-term general economic conditions. Recent Accounting Pronouncements - In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which helps simplify how entities account for income taxes by removing various exceptions related to the recognition of deferred tax liabilities and updating other tax computation requirements. This standard is effective for fiscal years beginning after December 15, 2020 and early adoption is permitted. The Company adopted ASU 2019-12 effective in the first quarter of fiscal year 2021. The adoption of ASU 2021-12 did not have a material impact on the Company's consolidated financial statements. In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in ASU 2020-10 contain improvements to the Codification to ensure consistency by including disclosure guidance in the appropriate Disclosure Section. This guidance includes an option for an entity to provide certain information either on the face of the financial statements or in the notes. The ASU also provides clarification to various codification topics to improve consistency in guidance application. The amendments are effective for interim and annual reporting periods in fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU 2020-10 effective in the first quarter of fiscal year 2021. The adoption of ASU 2020-10 did not have a material impact on the Company's condensed consolidated financial statements and related disclosures.

Debt Disclosure [Abstract]
Debt	Debt Credit Facility In June 2019, the Company entered into a credit facility with Bank of America and other named lenders, which has been periodically amended and restated and/or amended. The credit facility was amended and restated on March 11, 2020, and further amended on June 19, 2020, June 11, 2021 and December 16, 2021 (as amended to date, the "Credit Facility"). The Credit Facility, which matures on March 11, 2025, provides a senior secured revolving line of credit with a borrowing capacity of $250,000 and a term loan of $400,000. The term loan is subject to quarterly amortization payments. The Company paid $7,615 in debt issuance costs, of which $6,458 were allocated to the term debt and $1,157 were allocated to the line of credit. Loan fees allocated to the term debt will be amortized using the interest method and loan fees allocated to the line of credit will be amortized on a straight-line basis over the term of the Credit Facility. The Credit Facility provides for interest at a rate either based on the London Interbank Offered Rate, or LIBOR, plus a margin ranging from 1.00% to 2.25%, with a floor rate of 0.0%, or based on the base rate offered by Bank of America plus a margin ranging from 0.00% to 1.25%. At December 31, 2021, the one-month LIBOR and prime rates were 0.10% and 3.25%, respectively. At December 31, 2021 and January 1, 2021, our weighted average interest rates on outstanding borrowing were 1.31% and 1.62%, respectively. The Credit Facility is secured by substantially all of the Company’s assets, restricts the Company's ability to make certain payments and engage in certain transactions, and requires that the Company satisfy customary financial ratios. The Company was in compliance with the covenants as of December 31, 2021. On June 11, 2021, the Company terminated its existing swap agreement and entered into a new interest rate swap agreement to obtain a more favorable interest rate and to manage interest rate risk exposure, which was effective July 2, 2021. Through the interest rate swap agreement, the Company hedges the variability of cash flows in interest payments associated with $200,000 of its variable rate term debt. Refer to Note 11. " Derivatives and Hedging " for further details of this agreement. The Credit Facility permits up to $25,000 of the aggregate revolving commitment to be used by the Company for issuance of letters of credit, of which $15,000 was outstanding at December 31, 2021. The following table summarizes the line of credit under the Credit Facility: December 31, January 1, 2021 2021 Amount outstanding $ — $ — Standby letters of credit $ 15,000 $ 15,000 Available borrowing capacity $ 235,000 $ 235,000 Total borrowing capacity $ 250,000 $ 250,000 Maturity date March 11, 2025 As of December 31, 2021, future principal payments for long-term debt, including the current portion, as summarized as follows: December 31, 2021 For fiscal year 2022 $ 17,500 2023 20,000 2024 20,000 2025 325,000 Total 382,500 Debt issuance cost (4,047) Long-term debt, net of issuance cost 378,453 Less: current portion (17,500) Long-term debt less current portion $ 360,953

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is interest rate risk. The Company utilizes interest rate swaps to limit its exposure to interest rate risk by converting a portion of its floating-rate debt to a fixed-rate basis, thus reducing the impact of interest rate changes on future interest expense. Interest rate swaps involve the receipt of floating-rate amounts in exchange for fixed-rate interest payments based on the one-month LIBOR over the lives of the agreements without an exchange of the underlying principal amounts. As of December 31, 2021 and January 1, 2021, the Company had the following interest rate swap contracts: December 31, 2021 January 1, 2021 Effective Date Termination Date Notional Amount Unrealized Gain (Loss) in AOCI Unrealized Gain (Loss) in AOCI September 2, 2020 June 11, 2021 $200,000 $ 276 $ (915) July 2, 2021 March 11, 2025 $200,000 3,583 — Total $ 3,859 $ (915) On June 11, 2021, the Company terminated its existing swap agreement and entered into a new interest rate swap agreement with a notional amount of $200,000. The terminated swap resulted in an unrealized gain of $324 at the termination date that will continue to be accounted for in accumulated other comprehensive income and amortized into earnings over the term of the associated debt instrument. The new swap agreement (the "Interest Rate Swap") has a maturity date of March 11, 2025 and is indexed to a one-month LIBOR with a fixed leg of 0.50%. The Interest Rate Swap met the criteria for cash flow hedges under ASC 815, Derivatives and Hedging, and is recorded in other assets on the Consolidated Balance Sheet. Refer to Note 16. " Fair Value Measurements and Financial Instruments " for additional information on determining the fair value. The unrealized gains or losses, after tax, are recorded in Accumulated Other Comprehensive Income, a component of equity, and are expected to be reclassified into interest expense on the Consolidated Statement of Income when the forecasted transactions affect earnings. As required under ASC 815, the Interest Rate Swap’s effectiveness will be assessed on a quarterly basis using a quantitative regression analysis. The gains and losses, net of tax, related to the effective portion of derivative instruments designated as cash flow hedges recognized in Accumulated Other Comprehensive Income for the years ended December 31, 2021 and January 1, 2021 were a gain of $3,645 and a loss of $699, respectively. The gains and losses, related to the effective portion of derivative instruments designated as cash flow hedges recognized in Interest Expense for the years ended December 31, 2021 and January 1, 2021 were losses of $600 and $115, respectively. Unrealized losses of $814 included in accumulated other comprehensive income related to the Interest Rate Swap are expected to be recognized in interest expense over the next twelve months.

The net proceeds to the Company after underwriters' discounts and commissions of $11,015 and $511 of offering costs was $198,233. The total shares sold included 360 shares that were sold in connection with the underwriters' option to purchase additional shares. This offering was made pursuant to the Company's registration statement on Form S-3. The Company did not incur any expenses related to secondary offerings during the fiscal years ended December 31, 2021 and January 3, 2020. Equity Incentive Plans The Company has outstanding awards under the following equity incentive plans: the 2008 Stock Option Plan (the "2008 Plan"), the 2008 Non-Statutory Stock Option Plan (the "2008 Non-Statutory Plan") and the 2013 Omnibus Plan (the "2013 Plan"). No further awards will be granted pursuant to the 2008 Plan or the 2008 Non-Statutory Plan. Under the 2013 Plan, the Company has the ability to issue incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, RSUs, performance units and/or performance shares. The equity incentive plans are administered by the Compensation Committee of the Board of Directors of the Company, which has the authority to determine the type of incentive award, as well as the terms and conditions of the awards. Options granted under the plans have vesting periods ranging from one Stock-Based Compensation Compensation expense related to the Company's share-based awards for the fiscal years ended December 31, 2021, January 1, 2021, and January 3, 2020 was $13,914, $8,618, and $6,864, respectively, all of which related to RSUs. No compensation expense related to stock options was incurred during the fiscal years ended December 31, 2021, January 1, 2021, and January 3, 2020. The following table summarizes the allocation of stock-based compensation in the accompanying consolidated statements of income: For the fiscal years ended 2021 2020 2019 Cost of sales $ 710 $ 625 $ 802 Sales and marketing 803 635 506 Research and development 944 788 721 General and administrative 11,457 6,570 4,835 Total $ 13,914 $ 8,618 $ 6,864 As of January 1, 2021, $421 of stock-based compensation expense related to our executive bonus plan was included in Accrued Expenses on the Condensed Consolidated Balance Sheets. This amount was recognized as additional paid in capital during the year ended December 31, 2021 upon the issuance of the underlying restricted stock units. Stock-based compensation expense capitalized to inventory was not material for the years ended December 31, 2021, January 1, 2021 and January 3, 2020. Restricted Stock Units The Company grants both time-based and performance-based stock awards, which also include a time-based vesting feature. Compensation expense for time-based stock awards is measured at the grant date based on the closing market price of the Company's common stock, and recognized ratably over the vesting period. For performance-based stock awards, compensation expense is measured based on estimates of the number of shares ultimately expected to vest at each reporting date based on management’s expectations regarding the relevant performance criteria. The recognition of compensation expense associated with performance-based stock awards requires defined criteria for assessing achievement and judgment in assessing the probability of meeting the performance goals. The following table summarizes RSU activity: Unvested RSUs Number of shares outstanding Weighted-average grant date fair value Unvested at December 28, 2018 655 $ 29.34 Granted 131 74.70 Canceled (67) 32.29 Vested (292) 26.06 Unvested at January 3, 2020 427 44.98 Granted 260 47.46 Canceled (13) 48.51 Vested (224) 37.34 Unvested at January 1, 2021 450 50.12 Granted 89 149.08 Canceled (24) 56.21 Vested (177) 49.17 Unvested at December 31, 2021 338 $ 76.30 The fair value of vested RSUs was $27,213, $15,625 and $21,793 for the years ended December 31, 2021, January 1, 2021 and January 3, 2020, respectively. As of December 31, 2021, the Company had approximately $17,585 of unrecognized stock-based compensation expense related to RSUs, which will be recognized over the remaining weighted-average vesting period of approximately 2.05 years. Performance Stock Units During the year ended December 31, 2021, the Company issued performance share units (“PSUs”) to certain executives that represent shares potentially issuable in the future. Issuance is based upon the Company's performance, over a 2-3 year performance period, on certain measures including return on invested capital and free cash flow. The PSUs vest only upon the achievement of the applicable performance goals for the performance period, and, depending on the actual achievement on the performance goals, the grantee may earn between 0% and 200% of the target PSUs. The fair value of performance share units is calculated based on the stock price on the date of grant. The following table summarizes the activity for the Company's unvested PSUs for the year ended December 31, 2021: Unvested PSUs Number of shares outstanding Weighted-average grant date fair value Unvested at January 1, 2021 — $ — Granted 29 $ 141.46 Unvested at December 31, 2021 29 $ 141.46 The stock-based compensation expense recognized each period is dependent upon our estimate of the number of shares that will ultimately vest based on the achievement of certain performance conditions. Future stock-based compensation expense for unvested performance-based awards could reach a maximum of $5,528 assuming achievement at the maximum level. The unrecognized stock-based compensation expense is expected to be recognized over a weighted average period of 1.56 years. Stock Options The following table summarizes stock option activity: Number of shares outstanding Weighted-average exercise price Weighted-average remaining contractual life (years) Aggregate intrinsic value Balance at December 28, 2018 720 $ 5.17 3 $ 39,403 Options exercised (289) 5.03 17,422 Balance at January 3, 2020 431 5.27 2 27,814 Options exercised (206) 5.16 19,724 Balance at January 1, 2021 225 5.37 2 22,593 Options exercised (192) 5.41 25,751 Balance at December 31, 2021 33 5.16 1 5,389 Options vested and expected to vest - December 31, 2021 33 5.16 1 5,389 Options exercisable - December 31, 2021 33 5.16 1 5,389 Aggregate intrinsic value represents the difference between the closing price of the Company's common stock on NASDAQ and the exercise price of outstanding, in-the-money options. No options vested during the year ended December 31, 2021. As of December 31, 2021, stock-based compensation expense related to stock options has been fully recognized. During the years ended December 31, 2021, January 1, 2021 and January 3, 2020, 192, 206, and 289 shares of common stock, respectively, were issued due to the exercise of stock options, resulting in proceeds to the Company of approximately $1,042, $1,063, and $1,451, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share ("EPS") amounts are computed by dividing net income attributable to Fox Factory Holding Corp. stockholders for the period by the weighted average number of common shares outstanding during the period. Diluted EPS amounts are computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. Potentially dilutive common shares include shares issuable upon the exercise of outstanding stock options and vesting of restricted stock units, which are reflected in diluted earnings per share by application of the treasury stock method. The following table presents the calculation of basic and diluted earnings per share: For the fiscal years ended 2021 2020 2019 Net income attributable to FOX stockholders $ 163,818 $ 90,674 $ 93,033 Weighted average shares used to compute basic earnings per share 42,022 40,229 38,333 Dilutive effect of employee stock plans 344 572 822 Weighted average shares used to compute diluted earnings per share 42,366 40,801 39,155 Earnings per share: Basic $ 3.90 $ 2.25 $ 2.43 Diluted $ 3.87 $ 2.22 $ 2.38 The Company excluded some potentially dilutive shares from the calculation of diluted earnings per share for the year ended December 31, 2021, as these shares would have been antidilutive. No potentially dilutive shares were excluded from the calculation of diluted earnings per share for the years ended January 1, 2021 and January 3, 2020.

As of December 31, 2021, the Company assessed the realizability of deferred tax assets and evaluated the need for a valuation allowance for deferred tax assets for each jurisdiction based on the framework of ASC 740. As a result of the TCJA, the Company believes that it is more likely than not that a portion of its foreign tax credits will not be realizable, and as such, provided an allowance of $7,172 as of January 1, 2021. For the year ended December 31, 2021, the valuation allowance increased by $2,051, due to a generation of additional foreign tax credits from the foreign derived earnings. The valuation allowance for foreign tax credits was $9,161 as of December 31, 2021. Other components of the valuation allowance were not significant. It is reasonably possible that the Company could record a material adjustment to the valuation allowance in the next twelve months as management assesses the progress and outcome of its plans to alter the generation and utilization of foreign tax credits.

Fair Value Disclosures [Abstract]
Fair Value Measurement and Financial Instruments	Fair Value Measurement and Financial Instruments The FASB's Accounting Standards Codification 820, "Fair Value Measurements and Disclosures" requires the valuation of assets and liabilities required or permitted to be either recorded or disclosed at fair value based on hierarchy of available inputs as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following table presents the Company's hierarchy for its assets, liabilities and redeemable non-controlling interest measured at fair value on a recurring basis as of the following periods: December 31, 2021 January 1, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Interest Rate Swap — 3,583 — 3,583 — — — — Total assets measured at fair value $ — $ 3,583 $ — $ 3,583 $ — $ — $ — $ — Liabilities: Credit Facility $ — $ 378,453 $ — $ 378,453 $ — $ 389,588 $ — $ 389,588 Interest Rate Swap — — — — — 915 — 915 Total liabilities measured at fair value $ — $ 378,453 $ — $ 378,453 $ — $ 390,503 $ — $ 390,503 There were no transfers of assets or liabilities between Level 1, Level 2 and Level 3 categories of the fair value hierarchy during the years ended December 31, 2021, and January 1, 2021. The Company used Level 2 inputs to determine the fair value of the Credit Facility. The Company believes the carrying amount of its Credit Facility approximates the fair value at December 31, 2021 because, while subject to a minimum LIBOR floor rate, the interest rate approximates current market rates of debt with similar terms and comparable credit risk. On June 11, 2021 the Company entered into an interest rate swap agreement to mitigate the cash flow risk associated with changes in interest rates on its variable rate debt. Refer to Note 11. " Derivatives and Hedging " for additional details of the agreement. In accordance with ASC 815, Derivatives and Hedging Interest rate swap contract is recognized as an asset or liability on the Consolidated Balance Sheets and is measured at fair value. The fair value was calculated utilizing Level 2 inputs.

Change in Fiscal Year	Fiscal Year Calendar - The Company operates using a 52-53 week fiscal year calendar ending on the Friday nearest to December 31. Therefore, the financial results of certain fiscal years and quarters, which will contain 53 and 14 weeks, respectively, will not be exactly comparable to the prior and subsequent fiscal years and quarters, which contain 52 and 13 weeks, respectively. For the fiscal years 2021, 2020 and 2019, the Company's fiscal year ended on December 31, 2021, January 1, 2021 and January 3, 2020 and had 52, 52 and 53 weeks, respectively.
Principles of Consolidation	Principles of Consolidation - The consolidated financial statements include the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates - The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management’s estimates.
Foreign Currency Translation and Transaction	Foreign Currency Translation and Transaction - The functional currency of the Company’s non-U.S. entities is the local currency of the respective operations. The Company translates the financial statements of its non-U.S. entities into U.S. Dollars each reporting period for purposes of consolidation. Assets and liabilities of the Company’s foreign subsidiaries are translated at the period-end currency exchange rates while sales and expenses are translated at the average currency exchange rates in effect for the period. The effects of these translation adjustments are a component of other comprehensive income.
Cash and Cash Equivalents	Cash and Cash Equivalents - Cash consists of cash maintained in checking or money market accounts. All highly liquid investments purchased with an original maturity date of 90 days or less at the date of purchase are considered to be cash equivalents.
Accounts Receivable	Accounts Receivable - Accounts receivable are unsecured customer obligations which generally require payment within various terms from the invoice date. The receivables are stated at the invoice amount. Financing terms vary by customer. Invoices are considered past due when payment is not received within the terms stated within the contract. Payments of accounts receivable are applied to the specific invoices identified on the customer’s remittance advice or if unspecified, generally to the earliest unpaid invoices. The carrying amount of accounts receivable is reduced by a valuation allowance that reflects management’s best estimate of amounts that may not be collected. All accounts or portions thereof deemed to be uncollectible or that may require an excessive collection cost are written off to the allowance for credit losses.
Concentration of Credit Risk	Concentration of Credit Risk - Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and accounts receivable. As of December 31, 2021 the Company held $135,142 in cash at U.S. subsidiaries and $44,544 at subsidiaries outside the U.S. The account balances may significantly exceed the insurance coverage provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company has not experienced any losses in its uninsured accounts.
Allowance for Doubtful Accounts	Allowance for Credit Losses - The Company records a provision for credit losses based on historical experience and a detailed assessment of the collectability of its accounts receivable. The provision is based on how long a receivable has been outstanding, taking into account the historical credit loss rate and adjusting for both current conditions and forecasts of economic conditions into that expected credit loss rate. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer’s ability to meet its financial obligations, the Company’s estimate of the recoverability of the amounts due could be reduced by a material amount.
Inventories	Inventories - Inventories are stated at the lower of actual cost (or standard cost which generally approximates actual costs on a first-in first-out basis) or net realizable value. Cost includes raw materials and inbound freight, as well as direct labor and manufacturing overhead for products we manufacture. Net realizable value is based on current replacement cost for raw materials and on a net realizable value for finished goods. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolescence or impaired balances.
Property and Equipment	Property and Equipment - Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. Leasehold improvements are amortized on a straight-line basis over the terms of the lease, or the useful lives of the assets, whichever is shorter. The value assigned to land associated with buildings we own is not amortized. Depreciation and amortization periods for the Company’s property and equipment are as follows: Asset Classification Estimated useful life Building and building improvements 15-39 years Information systems, office equipment and furniture 3-7 years Internal-use computer software 10 years Land improvements 15 years Machinery and manufacturing equipment 5-15 years Transportation equipment 3-5 years
Internal Use Computer Software Costs	Internal-use Computer Software Costs - Costs incurred to purchase and develop computer software for internal use are capitalized during the application development and implementation stages. These software costs have been for enterprise-level business and finance software that is customized to meet the Company’s operational needs. Capitalized costs are included in property and equipment and are amortized on a straight-line basis over the estimated useful life of the software beginning when the software project is substantially complete and placed in service. The Company capitalized $5,847 in internal use computer software costs during the year ended December 31, 2021. Costs incurred during the preliminary project stage and costs for training, data conversion, and maintenance are expensed as incurred.
Impairment of Long-lived Assets	Impairment of Long-lived Assets - The Company periodically reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the assets, an impairment loss is recorded to write the assets down to their estimated fair values. Fair value is estimated based on discounted future cash flows.
Business Combinations	Business Combinations - The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. The Company allocates the purchase price of the acquisition to the tangible assets acquired, liabilities assumed and identifiable intangible assets acquired based on their estimated fair values. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred. During the measurement period, the Company records adjustments to provisional amounts recorded for assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could be up to one year after the transaction date, subsequent adjustments are recorded to the Company’s consolidated statements of income.
Goodwill and Intangible Assets	Goodwill and Intangible Assets - Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis, the Company makes a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. We completed our most recent annual impairment test in the third quarter of 2021 at which time we had a single reporting unit for purposes of assessing goodwill impairment. No impairment charges have been incurred to date.
Self Insurance	Self-Insurance - The Company is partially self-insured for its U.S. employee health and welfare benefits. The Company’s liability for self-insurance is based on claims filed and an estimate of claims incurred but not yet reported. The Company considers a number of factors, including historical claims information, when determining the amount of the accrual. Costs related to the administration of the plan and related claims are expensed as incurred. The Company has third-party insurance coverage to limit exposure for individually significant claims.
Revenue Recognition	Revenue Recognition - Revenues are generated from the sale of performance-defining products and systems to customers worldwide. The Company’s performance-defining products and systems are solutions that improve performance of powered vehicles and bikes. Powered vehicles include side-by-sides, on-road vehicles with off-road capabilities, off-road vehicles and trucks, ATVs, snowmobiles, specialty vehicles and applications, and motorcycles. Revenue is measured based on the consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer, generally at the time of shipment. Contracts are generally in the form of purchase orders and are governed by standard terms and conditions. For larger OEMs, the Company may also enter into master agreements. Sales tax and other similar taxes are excluded from revenues. Provisions for discounts, rebates, sales incentives, returns, and other adjustments are generally provided for in the period the related sales are recorded, based on management’s assessment of historical trends and projection of future results. Certain pricing provisions that provide the customer with future discounts are considered a material right. Such material rights result in the deferral of revenues that are recognized when the rights are exercised by the customer. Measuring the material rights requires judgments including forecasts of future sales and product mix.
Cost of Sales	Cost of Sales - Cost of sales primarily consists of materials and labor expense in the manufacturing of the Company’s products sold to customers. Cost of sales also includes provisions for excess and obsolete inventory, warranty costs, certain allocated costs for facilities, depreciation and other manufacturing overhead. Additionally, it includes stock-based compensation for personnel directly involved with manufacturing the Company’s product offerings.
Shipping and Handling Fees and Costs	Shipping and Handling Fees and Costs - The Company includes shipping and handling fees billed to customers in sales. Shipping costs associated with inbound freight are capitalized as part of inventory and included in cost of sales as products are sold.
Sales and Marketing	Sales and Marketing - Sales and marketing expenses include costs related to sales, customer service and marketing personnel, including their wages, employee benefits and related stock-based compensation, and occupancy related expenses. Other significant sales and marketing expenses include race support and sponsorships of events and athletes, advertising and promotions related to trade shows, travel and entertainment, and promotional materials, products and sales offices costs.
Research and Development	Research and Development - Research and development expenses consist primarily of salaries and personnel costs, including wages, employee benefits and related stock-based compensation for the Company’s engineering, research and development teams, occupancy related expenses, fees for third party consultants, service fees, and expenses for prototype tooling and materials, travel, and supplies. The Company expenses research and development costs as incurred.
General and Administrative	General and Administrative - General and administrative expenses include costs related to executive, finance, information technology, human resources and administrative personnel, including wages, employee benefits and related stock-based compensation expenses. The Company records professional and contract service expenses, occupancy related expenses associated with corporate locations and equipment, and legal expenses in general and administrative expenses.
Stock-Based Compensation	Stock-Based Compensation - The Company measures stock-based compensation for all stock-based awards, including stock options and restricted stock units (“RSUs”), based on their estimated fair values on the date of the grant and recognizes the stock-based compensation cost for time-vested awards on a straight-line basis over the requisite service period. For performance-based RSUs, the number of shares ultimately expected to vest is estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. To the extent shares are expected to vest, the stock-based compensation cost is recognized on a straight-line basis over the requisite service period. The fair value of each stock option granted is estimated using the Black-Scholes option-pricing model. The Company does not estimate forfeitures in recognizing stock-based compensation expense. The fair value of the RSUs is equal to the fair value of the Company’s common stock on the grant date of the award.
Income Taxes	Income Taxes - Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Operating loss and tax credit carryforwards are measured by applying currently enacted tax laws. Valuation allowances are provided when necessary to reduce net deferred tax assets to an amount that is more likely than not to be realized. The Company has elected to account for global intangible low-taxed income ("GILTI") in the year the tax is incurred, rather than recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years. The net GILTI inclusion for the year ended December 31, 2021 was fully offset by foreign tax credits associated with the income. The Company recognizes the tax effects of an uncertain tax position only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date and then only in an amount more likely than not to be sustained upon review by the tax authorities. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes.
Advertising	Advertising - Advertising costs are expensed as incurred and recorded as sales and marketing expenses on our Consolidated Statements of Income.
Warranties	Warranties - The Company offers limited warranties on its products generally for one
Segments	Segments - The Company has determined that it has a single operating and reportable segment; manufacturing, sale and service of performance-defining products. The Company considers operating segments to be components of the Company in which separate financial information is available that is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker for the Company is the Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance.
Fair Value Measurements and Financial Instruments	Fair Value Measurements and Financial Instruments - The Financial Accounting Standards Board ("FASB") has issued Accounting Standards Codification 820, Fair Value Measurements and Disclosures , that requires the valuation of assets and liabilities required or permitted to be either recorded or disclosed at fair value based on hierarchy of available inputs as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
Certain Significant Risks and Uncertainties	Certain Significant Risks and Uncertainties - The Company is subject to those risks common in manufacturing-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. Additionally, the Company has been impacted by the coronavirus (“COVID-19”) outbreak. The global outbreak of COVID-19 has negatively affected the U.S. and global economy, disrupted global supply chains, resulted in significant travel and transport restrictions, including mandated closures and orders to “shelter-in-place,” and created significant disruption of the financial markets. Despite the Company’s efforts to manage and remedy these impacts to the Company, the ultimate impact and the extent to which the COVID-19 pandemic will continue to affect the business, results of operation and financial condition is difficult to predict and depends on numerous evolving factors outside of the Company’s control including: the duration and scope of the pandemic; government, social, business and other actions that have been and will be taken in response to the pandemic; and the effect of the pandemic on short and long-term general economic conditions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which helps simplify how entities account for income taxes by removing various exceptions related to the recognition of deferred tax liabilities and updating other tax computation requirements. This standard is effective for fiscal years beginning after December 15, 2020 and early adoption is permitted. The Company adopted ASU 2019-12 effective in the first quarter of fiscal year 2021. The adoption of ASU 2021-12 did not have a material impact on the Company's consolidated financial statements. In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in ASU 2020-10 contain improvements to the Codification to ensure consistency by including disclosure guidance in the appropriate Disclosure Section. This guidance includes an option for an entity to provide certain information either on the face of the financial statements or in the notes. The ASU also provides clarification to various codification topics to improve consistency in guidance application. The amendments are effective for interim and annual reporting periods in fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU 2020-10 effective in the first quarter of fiscal year 2021. The adoption of ASU 2020-10 did not have a material impact on the Company's condensed consolidated financial statements and related disclosures.
