Basis of Presentation	1. The accompanying consolidated financial statements include the accounts of WW International, Inc. and all of its subsidiaries. The terms “Company” and “WW” as used throughout these notes are used to indicate WW International, Inc. and all of its operations consolidated for purposes of its financial statements. The Company’s “Digital” business refers to providing subscriptions to the Company’s digital product offerings, including Digital 360 and Personal Coaching + Digital. The Company’s “Workshops + (formerly known as “Studio + Digital”) “pay-as-you-go” members. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) and include all of the Company’s majority-owned subsidiaries. All entities acquired, and any entity of which a majority interest was acquired, are included in the consolidated financial statements from the date of acquisition. In the fourth quarter of fiscal 2020, the remaining 20% interest in Vigilantes do Peso Marketing Ltda. was transferred to the Company in a cashless exchange, resulting in the reclassification of the redeemable noncontrolling interest to equity. All intercompany accounts and transactions have been eliminated in consolidation. In fiscal 2020, the Company identified and recorded out-of-period adjustments related to income tax errors resulting from income tax receivables that should have been adjusted in prior fiscal years. The impact of correcting these errors, which were immaterial to prior period financial statements and corrected in the fourth quarter of fiscal 2020, increased provision for income taxes by $2,278 and decreased net income attributable to the Company by $2,278

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Fiscal Year The Company’s fiscal year ends on the Saturday closest to December 31 st Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to inventories, the impairment analysis for goodwill and other indefinite-lived intangible assets, revenue, share-based compensation, income taxes, tax contingencies and litigation. The Company bases its estimates on historical experience and on various other factors and assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. While all available information has been considered For example, the global outbreak of the coronavirus ( COVID-19) has had and will continue to have an adverse impact on the Company’s business as well as on the business environment and the markets in which it operates. This global health crisis has also had a significant adverse effect on overall economic conditions and the Company expects consumer demand to continue to be negatively impacted due to changes in consumer behavior and confidence and health concerns. The situation remains dynamic and subject to rapid and possibly significant change, with the United States and other countries continuing to struggle with rolling outbreaks of . Accordingly, the full extent of the magnitude and duration of the negative impact to the Company’s business from the COVID-19 pandemic cannot be predicted with certainty. The Company considered the impact of COVID-19 on the assumptions and estimates used when preparing this Annual Report on Form 10-K and the accompanying consolidated financial statements. These assumptions and estimates may change as new events occur and additional information is obtained, and such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity. Translation of Foreign Currencies For all foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated into U.S. dollars using the exchange rate in effect at the end of each reporting period. Income statement accounts Foreign currency gains and losses arising from the translation of intercompany receivables and intercompany payables with the Company’s international subsidiaries are recorded as a component of other expense, net, unless the receivable or payable is considered long-term in nature, in which case the foreign currency gains and losses are recorded as a component of accumulated other comprehensive loss. Cash Equivalents Cash and cash equivalents are defined as highly liquid investments with original maturities of three months or less. Cash balances may, at times, exceed insurable amounts. The Company believes it mitigates this risk by investing in or through major financial institutions. Cash includes balances due from third-party credit card companies. Inventories Inventories, which consist of finished goods, are stated at the lower of cost or net realizable value on a first-in, first-out basis, net of reserves for obsolescence and shrinkage. Property and Equipment Property and equipment are recorded at cost. For financial reporting purposes, equipment is depreciated on the straight-line method over the estimated useful lives of the assets (3 to 10 years). Leasehold improvements are amortized on the straight-line method over the shorter of the term of the lease or the useful life of the related assets. Expenditures for new facilities and improvements that substantially extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When assets are retired or otherwise disposed of, the cost and related depreciation are removed from the accounts and any related gains or losses are included in income. Impairment of Long Lived Assets The Company reviews long-lived assets, including amortizable intangible assets, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. In fiscal 2021, fiscal 2020 and fiscal 2019, the Company recorded impairment charges of $5, $62 and $307, respectively, related to internal-use computer software that was not expected to provide substantive service potential. In fiscal 2021, fiscal 2020 and fiscal 2019, the Company recorded impairment charges of $516, $1,310 and $0, respectively, related to property, plant and equipment that were expected to be disposed of before the end of their estimated useful lives. Franchise Rights Acquired Finite-lived franchise rights acquired are amortized over the remaining contractual period, which is generally less than one year. Indefinite-lived franchise rights acquired are tested on an annual basis for impairment. In performing the impairment analysis for indefinite-lived franchise rights acquired, the fair value for franchise rights acquired is estimated using a discounted cash flow approach referred to as the hypothetical start-up approach for franchise rights related to the Company’s Workshops Workshops In its hypothetical start-up approach analysis for fiscal 2021, the Company assumed that the year of maturity was reached after 7 years. Subsequent to the year of maturity, the Company estimated future cash flows for the Workshops Workshops Goodwill In performing the impairment analysis for goodwill, the fair value for the Company’s reporting units is estimated using a discounted cash flow approach. This approach involves projecting future cash flows attributable to the reporting unit and discounting those estimated cash flows using an appropriate discount rate. The estimated fair value is then compared to the carrying value of the reporting unit. The Company has determined the appropriate reporting unit for purposes of assessing annual impairment to be the country for all reporting units. The net book values of goodwill in the United States, Canada and other countries as of the January 1, 2022 balance sheet date were $105,121, $42,409 and $9,844, respectively, totaling $157,374. The net book values of goodwill in the United States, Canada and other countries as of the January 2, 2021 balance sheet date were $102,968, $42,103 and $10,546, respectively, totaling $155,617. For all of the Company’s reporting units tested as of May 9, 2021, the Company estimated future cash flows by utilizing the historical debt-free cash flows (cash flows provided by operations less capital expenditures) attributable to that country and then applied expected future operating income growth rates for such country. The Company utilized operating income as the basis for measuring its potential growth because it believes it is the best indicator of the performance of its business. The Company then discounted the estimated future cash flows utilizing a discount rate which was calculated using the weighted-average cost of capital, which included the cost of equity and the cost of debt. Indefinite-Lived Franchise Rights Acquired and Goodwill Annual Impairment Test The Company reviews indefinite-lived intangible assets, including franchise rights acquired with indefinite lives, and goodwill for potential impairment on at least an annual basis or more often if events so require. The Company performed fair value impairment testing as of May 9, 2021 and May 3, 2020, each the first day of fiscal May, on its indefinite-lived intangible assets and goodwill. In performing its annual impairment analysis as of May 9, 2021 and May 3, 2020, the Company determined that the carrying amounts of its franchise rights acquired with indefinite lives units of account and goodwill reporting units did not exceed their respective fair values and, therefore, no impairment existed. When determining fair value, the Company utilizes various assumptions, including projections of future cash flows, growth rates and discount rates. A change in these underlying assumptions could cause a change in the results of the impairment assessments and, as such, could cause fair value to be less than the carrying amounts and result in an impairment of those assets. In the event such a result occurred, the Company would be required to record a corresponding charge, which would impact earnings. The Company would also be required to reduce the carrying amounts of the related assets on its balance sheet. Based on the results of the Company’s May 9, 2021 annual franchise rights acquired impairment analysis performed for all of its units of account, all units, except for New Zealand, had an estimated fair value at least 45% higher than the respective unit’s carrying amount. Collectively, these units of account represent 99.4% of the Company’s total franchise rights acquired as of the January 1, 2022 balance sheet date. Based on the results of the Company’s annual franchise rights acquired impairment test performed for its New Zealand unit of account, which holds 0.6% of the Company’s franchise rights acquired as of the January 1, 2022 balance sheet date, the estimated fair value of this unit of account exceeded its carrying value by approximately 10%. Accordingly, a change in the underlying assumptions for New Zealand may change the results of the impairment assessment and, as such, could result in an impairment of the franchise rights acquired related to New Zealand, for which the net book value was $4,840 Based on the results of the Company’s May 9, 2021 annual goodwill impairment test performed for all of its reporting units, there was significant headroom in the goodwill impairment analysis for those units, with the difference between the carrying value and the fair value exceeding 100%. Canada Indefinite-Lived Franchise Rights Acquired Interim Impairment Test The Company’s Canada unit of account had a net book value of $60,117, 7.7% of its franchise rights acquired as of the January 1, 2022 balance sheet date. Given the lower headroom in the May 9, 2021 annual franchise rights acquired impairment test for this unit relative to the other units of account and the decline in business performance through fiscal 2021 (which may continue into fiscal 2022), the Company performed an interim impairment analysis as of January 1, 2022. In this test, the estimated fair value of this unit of account exceeded its carrying value by approximately 3%. Therefore, the Company did not record an impairment for the Canada unit of account. Brazil Goodwill Impairment With respect to its Brazil reporting unit, during the first quarter of fiscal 2020, the Company made a strategic decision to shift to an exclusively Digital business in that country. The Company determined that this decision, together with the negative impact of COVID-19, the ongoing challenging economic environment in Brazil and its reduced expectations regarding the reporting unit’s future operating cash flows, required the Company to perform an interim goodwill impairment analysis. In performing this discounted cash flow analysis, the Company determined that the carrying amount of this reporting unit exceeded its fair value and as a result recorded an impairment charge of $3,665, which comprised the remaining balance of goodwill for this reporting unit. As it related to its goodwill impairment analysis for Brazil, the Company estimated future debt-free cash flows in contemplation of its growth strategies for that market. In developing these projections, the Company considered the growth strategies under the current market conditions in Brazil. The Company then discounted the estimated future cash flows utilizing a discount rate which was calculated using the weighted-average cost of capital, which included the cost of equity and the cost of debt. Other Intangible Assets Other finite-lived intangible assets are amortized using the straight-line method over their estimated useful lives of 3 to 20 years. The Company expenses all software costs incurred during the preliminary project stage and capitalizes all internal and external direct costs of materials and services consumed in developing software once the development has reached the application development stage. Application development stage costs generally include software configuration, coding, installation to hardware and testing. These costs are amortized over their estimated useful life of 3 years for website development costs and from 3 to 5 years for all other software costs. All costs incurred for upgrades, maintenance and enhancements, including the cost of website content, which do not result in additional functionality, are expensed as incurred. Revenue Recognition Revenues are recognized when control of the promised services or goods is transferred to the Company’s customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those services or goods. The Company earns revenue from subscriptions for its digital products and by conducting workshops, for which it charges a fee, predominantly through commitment plans, as well as prepayment plans or the “pay-as-you-go” arrangement. The Company also earns revenue by selling consumer products online through its e-commerce platforms, at its studios, and through its trusted partners; collecting royalties related to licensing agreements; collecting royalties from franchisees; and publishing. Commitment plan revenues and prepaid workshop fees are recorded to revenue on a straight-line basis as control is transferred since these performance obligations are satisfied over time. “Digital Subscription Revenues,” consisting of the fees associated with subscriptions for the Company’s Digital products, including Digital 360 and Personal Coaching + Digital, are recognized on a straight-line basis as control is transferred since these performance obligations are satisfied over time. One-time Digital sign-up fees are considered immaterial in the context of the contract and the related revenue is amortized into revenue over the commitment period. “Workshops + Digital Fees” (formerly known as “Studio + Digital Fees”) Workshops The Company grants refunds in aggregate amounts that historically have not been material. Because the period of payment of the refund generally approximates the period revenue was originally recognized, refunds are recorded as a reduction of revenue over the same period. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The Company expenses sales commissions when incurred (amortization period would have been one year or less) and these expenses are recorded within selling, general and administrative expenses. The Company treats shipping and handling fees as fulfillment costs and not as a separate performance obligation, and as a result, any fees received from customers are included in the transaction price allocated to the performance obligation of providing goods with a corresponding amount accrued within cost of product sales and other for amounts paid to applicable carriers. Sales tax, value-added tax and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Advertising Costs Advertising costs consist primarily of broadcast and digital media. All costs related to advertising are expensed in the period incurred, except for media production-related costs, which are expensed the first time the advertising takes place. Total advertising expenses for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 were $252,754, $248,473 and $235,826, respectively. Income Taxes Deferred income tax assets and liabilities result primarily from temporary differences between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which differences are expected to reverse. If it is more-likely-than-not that some portion of a deferred tax asset will not be realized, a valuation allowance is recognized. The Company considers historic levels of income, estimates of future taxable income and feasible tax planning strategies in assessing the need for a tax valuation allowance. The Company recognizes a benefit for uncertain tax positions when a tax position taken or expected to be taken in a tax return is more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company recognizes accrued interest and penalties associated with uncertain tax positions as part of the provision for income taxes on its consolidated statements of net income. In addition, assets and liabilities acquired in purchase business combinations are assigned their fair values and deferred taxes are provided for lower or higher tax bases. Derivative Instruments and Hedging The Company is exposed to certain risks related to its ongoing business operations, primarily interest rate risk and foreign currency risk. Interest rate swaps were entered into to hedge a portion of the cash flow exposure associated with the Company’s variable-rate borrowings. The Company does not use any derivative instruments for trading or speculative purposes. The Company recognizes the fair value of all derivative instruments as either assets or liabilities on the balance sheet. The Company has designated and accounted for interest rate swaps as cash flow hedges of its variable-rate borrowings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive loss and reclassified into earnings in the periods during which the hedged transactions affect earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The fair value of the Company’s interest rate swaps is reported as a component of accumulated other comprehensive loss on its balance sheet. See Note 18 for a further discussion regarding the fair value of the Company’s interest rate swaps. The net effect of the interest payable and receivable under the Company’s effective interest rate swap is included in interest expense on its consolidated statements of net income. Deferred Financing Costs Deferred financing costs consist of fees paid by the Company as part of the establishment, exchange and/or modification of the Company’s long-term debt. Amortization expense for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 was $6,136, $8,845 and $9,318, respectively.

Accounting Changes And Error Corrections [Abstract]
Accounting Standards Adopted in Current Year and Recently Issued Accounting Pronouncements	3. In December 2019, the Financial Accounting Standards Board (the “FASB”) On January 3, 2021, the Company adopted the on a prospective basis, which did not have a material impact on its consolidated financial statements. 2 1 . In October 2021, the FASB issued updated guidance that requires an acquiring entity to apply Topic 606 to recognize and measure contract assets and contract liabilities acquired in a business combination. The effective date of the new guidance for public companies is for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption is permitted. The new guidance should be applied prospectively to business combinations occurring on or after its effective date. Although the Company is currently evaluating the timing of adoption for this guidance, it does not expect the adoption to have a material impact on its consolidated financial statements.

Leases [Abstract]
Leases	4. Leases A lease is defined as an arrangement that contractually specifies the right to use and control an identified asset for a specific period of time in exchange for consideration. Operating leases are included in operating lease assets, portion of operating lease liabilities due within one year, and long-term operating lease liabilities in the Company’s consolidated balance sheets. Finance leases are included in property and equipment, net, other accrued liabilities, and other long-term liabilities in the Company’s consolidated balance sheets. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term, using the Company’s incremental borrowing rate commensurate with the lease term, since the Company’s lessors do not provide an implicit rate, nor is one readily available. The incremental borrowing rate is calculated based on the Company’s credit yield curve and adjusted for collateralization, credit quality and economic environment impact, all where applicable. The lease asset includes scheduled lease payments and excludes lease incentives, such as free rent periods and tenant improvement allowances. The Company has certain leases that may include an option to renew and when it is reasonably probable to exercise such option, the Company will include the renewal option terms in determining the lease asset and lease liability. The Company does not have any renewal options that would have a material impact on the terms of the leases and that are also reasonably expected to be exercised as of January 1, 2022 The Company has lease agreements with lease and non-lease components and has elected not to separate non-lease components from lease components and instead to account for each separate lease component and non-lease component as a single lease component. The Company has elected the short-term lease exception accounting policy, whereby the recognition requirements of the updated guidance is not applied and lease expense is recorded on a straight-line basis with respect to leases with an initial term of 12 months or less. The Company’s operating leases are primarily for its studios and corporate offices.

Goodwill And Intangible Assets Disclosure [Abstract]
Franchise Rights Acquired, Goodwill and Other Intangible Assets	7 . Franchise Rights Acquired, Goodwill and Other Intangible Assets The Company performed its annual impairment review of indefinite-lived intangible assets, including franchise rights acquired with indefinite lives, and goodwill In performing its annual impairment analysis as of May 9, 2021 and May 3, 2020, the Company determined that the carrying amounts of its franchise rights acquired with indefinite lives units of account and goodwill reporting units The Company performed an interim impairment analysis as of January 1, 2022 for the Canada indefinite-lived franchise rights acquired and determined the carrying amount for this unit of account did not exceed its respective fair value and therefore, no impairment existed. With respect to its Brazil reporting unit, during the first quarter of fiscal 2020, the Company made a strategic decision to shift to an exclusively Digital business in that country. The Company determined that this decision, together with the negative impact of COVID-19, the ongoing challenging economic environment in Brazil and its reduced expectations regarding the reporting unit’s future operating cash flows, required the Company to perform an interim goodwill impairment analysis. In performing this discounted cash flow analysis, the Company determined that the carrying amount of this reporting unit exceeded its fair value and as a result recorded an impairment charge of $3,665 , which comprised the remaining balance of goodwill for this reporting unit. Franchise rights acquired are due to acquisitions of the Company’s franchised territories as well as the acquisition of franchise promotion agreements and other factors associated with the acquired franchise territories. For the fiscal year ended January 1, 2022, the change in the carrying value of franchise rights acquired was due to the franchisee acquisitions as described in Note 6 and the effect of exchange rate changes. Goodwill primarily relates to the acquisition of the Company by The Kraft Heinz Company (successor to H.J. Heinz Company ) in 1978 , and the Company’s acquisition s of W W.com, LLC (formerly known as WW.com, Inc. and WeightWatchers.com, Inc.) in 2005 and the Company’s franchised territories.

On April 13, 2021, the Company (1) repaid in full approximately $1,189,750 in aggregate principal amount of senior secured tranche B term loans due in 2024 under its then-existing credit facilities and (2) redeemed all of the $300,000 in aggregate principal amount of its then-outstanding 8.625% Senior Notes due in 2025 (the “Discharged Senior Notes”). On April 13, 2021, the Company’s then-existing credit facilities included a senior secured revolving credit facility (which included borrowing capacity available for letters of credit) due in 2022 with $175,000 in an aggregate principal amount of commitments. There were no outstanding borrowings under such revolving credit facility on that date. The Company funded such repayment of loans and redemption of notes with cash on hand as well as with proceeds received from approximately $1,000,000 in an aggregate principal amount of borrowings under its new credit facilities and proceeds received from the issuance of $500,000 in aggregate principal amount of 4.500% Senior Secured Notes due 2029 (the “Senior Secured Notes”). These transactions are collectively referred to herein as the “April 2021 debt refinancing”. The Company’s new credit facilities consist of a $1,000,000 term loan facility and a $175,000 revolving credit facility (which includes borrowing capacity available for letters of credit) (collectively, as amended from time to time, the “New Credit Facilities”). During the second quarter of fiscal 2021, t New Credit Facilities The New Credit Facilities were issued under a credit agreement, dated April 13, 2021 (as amended from time to time, the “New Credit Agreement”), among the Company, as borrower, the lenders party thereto, and Bank of America, N.A. (“Bank of America”), as administrative agent and an issuing bank. The New Credit Facilities consist of (1) $1,000,000 in aggregate principal amount of senior secured tranche B term loans due in 2028 (the “New Term Loan Facility”) and (2) $175,000 in an aggregate principal amount of commitments under a senior secured revolving credit facility (which includes borrowing capacity available for letters of credit) due in 2026 (the “New Revolving Credit Facility”). In December 2021, the Company made voluntary prepayments at par in an aggregate amount of $52,500 in respect of its outstanding term loans under the New Term Loan Facility As of January 1, 2022, the Company had $945,000 in an aggregate principal amount of loans outstanding under the New Credit Facilities, with $173,911 of availability and $1,089 in issued but undrawn letters of credit outstanding under the New Revolving Credit Facility. There were no outstanding borrowings under the New Revolving Credit Facility as of January 1, 2022. All obligations under the New Credit Agreement are guaranteed by, subject to certain exceptions, each of the Company’s current and future wholly-owned material domestic restricted subsidiaries. All obligations under the New Credit Agreement, and the guarantees of those obligations, are secured by substantially all of the assets of the Company and each guarantor, subject to customary exceptions, including: • a pledge of 100% of the equity interests directly held by the Company and each guarantor in any wholly-owned material subsidiary of the Company or any guarantor (which pledge, in the case of any non-U.S. subsidiary of a U.S. subsidiary, will not include more than 65% of the voting stock of such first-tier non-U.S. subsidiary), subject to certain exceptions; and • a security interest in substantially all other tangible and intangible assets of the Company and each guarantor, subject to certain exceptions. The New Credit Facilities require the Company to prepay outstanding term loans, subject to certain exceptions, with: • 50 • 100 • 100 The foregoing mandatory prepayments will be used to reduce the installments of principal on the New Term Loan Facility. The Company may voluntarily repay outstanding loans under the New Credit Facilities at any time without penalty, except for customary “breakage” costs with respect to LIBOR loans under the New Credit Facilities. Borrowings under the New Term Loan Facility bear interest at a rate per annum equal to, at the Company’s option, either (1) an applicable margin plus a base rate determined by reference to the highest of (a) 0.50% per annum plus the Federal Funds Effective Rate as determined by the Federal Reserve Bank of New York, (b) the prime rate of Bank of America and (c) the LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%; provided that such rate is not lower than a floor of 1.50% or (2) an applicable margin plus a LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, provided that LIBOR is not lower than a floor of 0.50%. Borrowings under the New Revolving Credit Facility bear interest at a rate per annum equal to an applicable margin based upon a leverage-based pricing grid, plus, at the Company’s option, either (1) a base rate determined by reference to the highest of (a) 0.50% per annum plus the Federal Funds Effective Rate as determined by the Federal Reserve Bank of New York, (b) the prime rate of Bank of America and (c) the LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for an interest period of one month adjusted for certain additional costs, plus 1.00%; provided that such rate is not lower than a floor of 1.00% or (2) a LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, provided such rate is not lower than a floor of zero. As of January 1, 2022, the applicable margins for the LIBOR rate borrowings under the New Term Loan Facility and the New Revolving Credit Facility were 3.50% and 2.75%, respectively. In the event that LIBOR is phased out as is currently expected, the New Credit Agreement provides that the Company and the administrative agent may amend the New Credit Agreement to replace the LIBOR definition therein with a successor rate subject to notifying the lending syndicate of such change and not receiving within five business days of such notification objections to such replacement rate from lenders holding at least a majority of the aggregate principal amount of loans and commitments then outstanding under the New Credit Agreement; provided that such lending syndicate may not object to a SOFR-based successor rate contained in any such amendment. If the Company fails to do so, its borrowings will be based off of the alternative base rate plus a margin. On a quarterly basis, the Company pays a commitment fee to the lenders under the New Revolving Credit Facility in respect of unutilized commitments thereunder, which commitment fee fluctuates depending upon the Company’s Consolidated First Lien Leverage Ratio (as defined in the New Credit Agreement). The New Credit Agreement contains other customary terms, including (1) representations, warranties and affirmative covenants, (2) negative covenants, including limitations on indebtedness, liens, mergers, acquisitions, asset sales, investments, distributions, prepayments of subordinated debt, amendments of material agreements governing subordinated indebtedness, changes to lines of business and transactions with affiliates, in each case subject to baskets, thresholds and other exceptions, and (3) customary events of default. The availability of certain baskets and the ability to enter into certain transactions are also subject to compliance with certain financial ratios. In addition, if the aggregate principal amount of extensions of credit outstanding under the New Revolving Credit Facility as of any fiscal quarter end exceeds 35% of the amount of the aggregate commitments under the New Revolving Credit Facility in effect on such date, the Company must be in compliance with a Consolidated First Lien Leverage Ratio of, on or prior to the end of the first fiscal quarter of 2022, 6.00:1.00, with a step down to 5.75:1.00 for the period ending after the first fiscal quarter of 2022 through and including with first fiscal quarter of 2023, with an additional step down to 5.50:1.00 for the period ending after the first fiscal quarter of 2023 through and including with first fiscal quarter of 2024, with a step down to 5.25:1.00 for the period ending after the first fiscal quarter of 2024 through and including with first fiscal quarter of 2025 and again to 5.00:1.00, for the period following the first fiscal quarter of 2025. Senior Secured Notes The Senior Secured Notes were issued pursuant to an Indenture, dated as of April 13, 2021 (as amended, supplemented or modified from time to time, the “New Indenture”), among the Company, the guarantors named therein and The Bank of New York Mellon, as trustee and notes collateral agent. The New Indenture contains customary terms, events of default and covenants for an issuer of non-investment grade debt securities. These covenants include limitations on indebtedness, liens, mergers, acquisitions, asset sales, investments, distributions, prepayments of subordinated debt and transactions with affiliates, in each case subject to baskets, thresholds and other exceptions. The Senior Secured Notes accrue interest at a rate per annum equal to 4.500% and will mature on April 15, 2029. Interest on the Senior Secured Notes is payable semi-annually on April 15 and October 15 of each year, beginning on October 15, 2021. On or after April 15, 2024, the Company may on any one or more occasions redeem some or all of the Senior Secured Notes at a purchase price equal to 102.250% of the principal amount of the Senior Secured Notes, plus accrued and unpaid interest, if any, to, but not including, the redemption date, such optional redemption price decreasing to 101.125% on or after April 15, 2025 and to 100.000% on or after April 15, 2026. Prior to April 15, 2024, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount of the Senior Secured Notes with an amount not to exceed the net proceeds of certain equity offerings at 104.500% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the redemption date. Prior to April 15, 2024, the Company may redeem some or all of the Senior Secured Notes at a make-whole price plus accrued and unpaid interest, if any, to, but not including, the redemption date.

If a change of control occurs, the Company must offer to purchase for cash the Senior Secured Notes at a purchase price equal to 101% of the principal amount of the Senior Secured Notes, plus accrued and unpaid interest, if any, to, but not including, the purchase date. Following the sale of certain assets and subject to certain conditions, the Company must offer to purchase for cash the Senior Secured Notes at a purchase price equal to 100% of the principal amount of the Senior Secured Notes, plus accrued and unpaid interest, if any, to, but not including, the purchase date. The Senior Secured Notes are guaranteed on a senior secured basis by the Company’s subsidiaries that guarantee the New Credit Facilities.

Stock Plans	1 2 . Incentive Compensation Plans and Winfrey Amendment Option On May 6, 2008, the Company’s shareholders approved the 2008 Stock Incentive Plan (the “2008 Plan”). On May 6, 2014, the Company’s shareholders approved the 2014 Stock Incentive Plan (as amended and restated, the “2014 Plan”, and together with the 2008 Plan, the “Stock Plans”), which replaced the 2008 Plan for all equity-based awards granted on or after May 6, 2014. The 2014 Plan is designed to promote the long-term financial interests and growth of the Company by attracting, motivating and retaining employees with the ability to contribute to the success of the business and to align compensation for the Company’s employees over a multi-year period directly with the interests of the shareholders of the Company. The Company’s long-term equity incentive compensation program has historically included time-vesting non-qualified stock option and/or restricted stock unit (“RSUs”) (including performance-based stock unit with both time- and performance-vesting criteria (“PSUs”)) awards. From time to time, the Company has granted fully-vested shares of its common stock to individuals in connection with special circumstances. The Company’s Board of Directors or a committee thereof administers the 2014 Plan. Under the 2014 Plan, grants may take the following forms at the Company’s Board of Directors’ Compensation and Benefits Committee’s (the “Compensation Committee”) discretion: non-qualified stock options, incentive stock options, stock appreciation rights, RSUs, restricted stock and other stock-based awards. As of January 1, 2022, the maximum number of shares of common stock available for grant under the 2014 Plan was 12,500, subject to increase and adjustment as set forth in the 2014 Plan. Under the 2014 Plan, the Company also grants fully-vested shares of its common stock to certain members of its Board of Directors. While these shares are fully vested, the directors are restricted from selling these shares while they are still serving on the Company’s Board of Directors subject to limited exceptions. During the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019, the Company granted to members of the Company’s Board of Directors an aggregate of 29, 31 and 29 fully-vested shares, respectively, and recognized compensation expense of $757, $688 and $756, respectively. Under the Winfrey Amendment Option ( as defined below), in fiscal 2020 The Company issues common stock for share-based compensation awards from treasury stock. The total compensation cost that has been charged against income for share-based compensation awards and the Winfrey Amendment Option, as applicable, was $21,348, $55,013 and $20,471 for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019, respectively. Such amounts have been included as a component of selling, general and administrative expenses. The total income tax benefit recognized in the Company’s consolidated statements of net income for all share-based compensation awards was $5,175, $10,915 and $2,141 for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019, respectively.

No compensation costs were capitalized. As of January 1, 2022, there was $31,877 of total unrecognized compensation cost related to the stock options, RSUs and PSUs granted under the Stock Plans. That cost is expected to be recognized over a weighted-average period of approximately 1.5 years. Stock Option Awards with Time-Vesting Criteria Stock options with time-vesting criteria (“Time-Vesting Options”) are exercisable based on the terms and conditions outlined in the applicable award agreement. Time-Vesting Options outstanding at January 1, 2022, January 2, 2021 and December 28, 2019 vest over a period of two to four years and the expiration term is seven to ten years. Time-Vesting Options outstanding at January 1, 2022, January 2, 2021 and December 28, 2019 have an exercise price between $3.97 and $60.00 per share. The Company did not grant Time-Vesting Options in fiscal 2019. The fair value of each of these option awards is estimated on the date of grant using the Black-Scholes option pricing model with the weighted average assumptions noted in the following table. Expected volatility is based on the historical volatility of the Company’s common stock.

The Company maintains a full valuation allowance on its state and certain foreign net operating loss carryforwards as it is deemed more likely than not that such losses will not be realized. In fiscal 2021, the Company recorded a $1,560 income tax benefit for the release in the valuation allowance related to its operations in Switzerland. As a result of the Tax Cuts and Jobs Act (the “2017 Tax Act”) changing the U.S. to a modified territorial tax system, the Company will no longer assert its $80,892 of undistributed foreign earnings as of January 1, 2022 are permanently reinvested. The Company has considered whether there would be any potential future costs of not asserting indefinite reinvestment and does not expect such costs to be significant. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Fiscal Year Ended January 1, January 2, December 28, 2022 2021 2019 Balance at beginning of year $ 851 $ 206 $ 3,665 Increases related to tax positions taken in current year 196 — — Increases related to tax positions taken in prior years 260 605 264 Reductions related to tax positions taken in prior years (199 ) — (2,731 ) Reductions related to settlements with tax authorities — — (992 ) Effects of foreign currency translation (53 ) 40 — Balance at end of year $ 1,055 $ 851 $ 206 At January 1, 2022, the total amount of unrecognized tax benefits that, if recognized, would affect the Company’s effective tax rate is $985. In fiscal 2021, the Company reached a favorable settlement with the IRS for the 2018 tax year, which resulted in no adjustment, and closed an audit in Germany for tax years 2013 to 2016, which resulted in an assessment of $529. The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. At January 1, 2022, with few exceptions, the Company was no longer subject to U.S. federal, state or local income tax examinations by tax authorities for years prior to 2018, or non-U.S. income tax examinations by tax authorities for years prior to 2016. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company had $ (54) and $ of accrued interest and penalties at January 1, 2022 and January 2, 2021 , respectively. The Company recognized $ , $ 190 and $ (257) of an income tax expense (benefit) in interest and penalties during the fiscal years ended January 1, 2022 , January 2, 2021 and December 28, 2019 , respectively.

Compensation And Retirement Disclosure [Abstract]
Employee Benefit Plans	1 4 . The Company sponsors the Third Amended and Restated WW Savings Plan (the “Savings Plan”) for salaried and certain hourly U.S. employees of the Company. The Savings Plan is a defined contribution plan that provides for employer matching contributions of 50% of the employee’s tax deferred contributions up to 6% of an employee’s eligible compensation for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019. Effective as of May 30, 2020, the Company temporarily suspended employer matching contributions through December 31, 2020. During fiscal 2014, the Company received a favorable determination letter from the IRS that qualifies the Savings Plan under Section 401(a) of the Internal Revenue Code. Pursuant to the Savings Plan, the Company also makes profit sharing contributions for all full-time salaried U.S. employees who are eligible to participate in the Savings Plan (except for certain personnel above a determined compensation level). The profit sharing contribution is a guaranteed monthly employer contribution on behalf of each participant based on the participant’s age and a percentage of the participant’s eligible compensation. The Savings Plan also has a discretionary supplemental profit sharing employer contribution component that is determined annually by the Compensation Committee. Effective as of May 30, 2020, the Company temporarily suspended profit sharing contributions through December 31, 2020. Expense related to these contributions for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 was $1,342, $914 and $1,313, respectively. For certain U.S. personnel above a determined compensation level, the Company sponsors the Second Amended and Restated Weight Watchers Executive Profit Sharing Plan (“EPSP”). Under the IRS definition, the EPSP is considered a Nonqualified Deferred Compensation Plan. There is a promise of payment by the Company made on the employees’ behalf instead of an individual account with a cash balance. The EPSP provides for a guaranteed employer contribution on behalf of each participant based on the participant’s age and a percentage of the participant’s eligible compensation. The EPSP has a discretionary supplemental employer contribution component that is determined annually by the Compensation Committee. The EPSP is valued at the end of each fiscal month, based on an annualized interest rate of prime plus 2%, with an annualized cap of 15%. Effective as of May 30, 2020, the Company temporarily suspended EPSP contributions through December 31, 2020. Expense related to this commitment for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 was $3,975, $1,761 and $3,691, respectively.

Commitments and Contingencies	16. Securities Class Action and Derivative Matters In March 2019, two substantially identical class action complaints alleging violations of the federal securities laws were filed by individual shareholders against the Company, certain of the Company’s current officers and the Company’s former controlling shareholder, Artal Group S.A. (“Artal”), in the United States District Court for the Southern District of New York. The actions were consolidated and lead plaintiffs were appointed in June 2019. A consolidated amended complaint was filed on July 29, 2019, naming as defendants the Company, certain of the Company’s current officers and directors, and Artal and certain of its affiliates. A second consolidated amended complaint was filed on September 27, 2019. The operative complaint asserted claims on behalf of all purchasers of the Company’s common stock between May 4, 2018 and February 26, 2019, inclusive (the “Class Period”), including purchasers of the Company’s common stock traceable to the May 2018 secondary offering of the Company’s common stock by certain of its shareholders. The complaint alleged that, during the Class Period, the defendants disseminated materially false and misleading statements and/or concealed or recklessly disregarded material adverse facts. The complaint alleged claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, and with respect to the secondary offering, under Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended. The plaintiffs sought to recover unspecified damages on behalf of the class members. The Company filed a motion to dismiss the complaint on October 31, 2019. On November 30, 2020, the Court granted the Company’s motion to dismiss in full and dismissed the complaint. The plaintiffs did not appeal. Between March and July 2019 Subsequently, on August 17, 2021, Stipulation of Settlement as well as the Proposed Order and Final Judgment in On November 30, 2021, Order and Final Judgment, and on January 7, 2022, the Order and Final Judgment and the dismissal of the has passed. Federal Trade Commission Matter The Company received a letter from the U.S. Federal Trade Commission (the “FTC”) dated September 3, 2019, advising that the FTC was conducting a non-public inquiry into the practices of the Company's wholly owned subsidiary Kurbo, Inc. (“Kurbo”) relating to the collection, use, disclosure and sharing of personal information. Kurbo offers a paid private coaching service as well as a free app to help families teach children healthy habits. The FTC focused on whether certain practices in the Kurbo free app complied with the Children's Online Privacy Protection Act ("COPPA"). On February 16, 2022, the FTC filed a complaint and proposed settlement order in the U nited States District Court for the Northern District of California to resolve allegations that Kurbo violated COPPA by failing to provide required notices and obtain verifiable parental consent prior to collecting, using, and disclosing personal information from children using the Kurbo app. In connection with the proposed settlement, Kurbo and the Company are required, among other things: (i) to update their procedures to ensure that they obtain verifiable parental consent before collecting personal information from children, (ii) to destroy all of the personal information they may have obtained without verifiable parental consent as well as any models or algorithms based on that information, (iii) to update their records retention policy to require destruction of user information one year after a child stops tracking in the Kurbo app, and (iv) to pay a civil penalty of $1,500. Kurbo and the Company deny all of the material allegations in the FTC complaint and deny that either Kurbo or the Company ever violated COPPA or otherwise engaged in any wrongdoing. They entered into the settlement solely to resolve the matter and avoid the expense of litigation. The settlement will become final when the court enters the Consent Order. Other Litigation Matters Due to the nature of the Company’s activities, it is also, at times, subject to other pending and threatened legal actions that arise out of the ordinary course of business. In the opinion of management, the disposition of any such matters is not expected, individually or in the aggregate, to have a material adverse effect on the Company’s results of operations, financial condition or cash flows. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that the Company’s results of operations, financial condition or cash flows could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions. Commitments Minimum commitments under non-cancelable purchase obligations at January 1, 2022 were $18,861, of which $9,378 is due in fiscal 2022, $7,544 is due in fiscal 2023 and the remaining $1,939 is due in fiscal 2024.

Fair Value Disclosures [Abstract]
Fair Value Measurements	1 8 . Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. When measuring fair value, the Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs. Fair Value of Financial Instruments The Company’s significant financial instruments include long-term debt and interest rate swap agreements as of January 1, 2022 and January 2, 2021. Since there were no outstanding borrowings under the New Revolving Credit Facility as of January 1, 2022, the fair value approximated a carrying value of $0 at January 1, 2022. The fair value of the Company’s Credit Facilities is determined by utilizing average bid prices on or near the end of each fiscal quarter (Level 2 input). As of January 1, 2022 and January 2, 2021, the fair value of the Company’s long-term debt was approximately $1,389,306 and $1,501,148, respectively, as compared to the carrying value (net of deferred financing costs and debt discount) of $1,418,104 and $1,485,800, respectively. Derivative Financial Instruments The fair values for the Company’s derivative financial instruments are determined using observable current market information such as the prevailing LIBOR interest rate and LIBOR yield curve rates and include consideration of counterparty credit risk. See Note 19 for disclosures related to derivative financial instruments. The following table presents the aggregate fair value of the Company’s derivative financial instruments: Fair Value Measurements Using: Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Interest rate swap liability at January 1, 2022 $ 14,670 $ — $ 14,670 $ — Interest rate swap liability at January 2, 2021 $ 28,283 $ — $ 28,283 $ — The Company did not have any transfers into or out of Levels 1 and 2 and did not maintain any assets or liabilities classified as Level 3 during the fiscal years ended January 1, 2022 and January 2, 2021.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging	1 9 . As of January 1, 2022 and January 2, 2021, the Company had in effect interest rate swaps with an aggregate notional amount totaling $500,000 and $750,000, respectively. On July 26, 2013, in order to hedge a portion of its variable rate debt, the Company entered into a forward-starting interest rate swap with an effective date of March 31, 2014 and a termination date of April 2, 2020. The initial notional amount of this swap was $1,500,000. During the term of this swap, the notional amount decreased from $1,500,000 effective March 31, 2014 to $1,250,000 on April 3, 2017 and to $1,000,000 on April 1, 2019. This interest rate swap effectively fixed the variable interest rate on the notional amount of this swap at 2.41%. On June 11, 2018, in order to hedge a portion of its variable rate debt, the Company entered into a forward-starting interest rate swap (the “2018 swap”) with an effective date of April 2, 2020 and a termination date of March 31, 2024. The initial notional amount of this swap was $500,000. During the term of this swap, the notional amount decreased from $500,000 effective April 2, 2020 to $250,000 on March 31, 2021. This interest rate swap effectively fixed the variable interest rate on the notional amount of this swap at 3.1005%. On June 7, 2019, in order to hedge a portion of its variable rate debt, the Company entered into a forward-starting interest rate swap (together with the 2018 swap, the “current swaps”) with an effective date of April 2, 2020 and a termination date of March 31, 2024. The notional amount of this swap is $250,000. This interest rate swap effectively fixed the variable interest rate on the notional amount of this swap at 1.901%. The current swaps qualify for hedge accounting and, therefore, changes in the fair value of the current swaps have been recorded in accumulated other comprehensive loss. As of January 1, 2022 and January 2, 2021, cumulative unrealized losses for qualifying hedges were reported as a component of accumulated other comprehensive loss in the amounts of $10,843 ($14,622 before taxes) and $20,979 ($28,161 before taxes), respectively. As of January 1, 2022 and January 2, 2021, the aggregate $28,283, respectively, which were included in derivative payable in the consolidated balance sheets. The Company is hedging forecasted transactions for periods not exceeding the next three years. The Company expects approximately $4,566 ($6,103 before taxes) of derivative losses included in accumulated other comprehensive loss at January 1, 2022, based on current market rates, will be reclassified into earnings within the next 12 months.

Accounting Policies [Abstract]
Fiscal Year	Fiscal Year The Company’s fiscal year ends on the Saturday closest to December 31 st
Use of Estimates	Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to inventories, the impairment analysis for goodwill and other indefinite-lived intangible assets, revenue, share-based compensation, income taxes, tax contingencies and litigation. The Company bases its estimates on historical experience and on various other factors and assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. While all available information has been considered For example, the global outbreak of the coronavirus ( COVID-19) has had and will continue to have an adverse impact on the Company’s business as well as on the business environment and the markets in which it operates. This global health crisis has also had a significant adverse effect on overall economic conditions and the Company expects consumer demand to continue to be negatively impacted due to changes in consumer behavior and confidence and health concerns. The situation remains dynamic and subject to rapid and possibly significant change, with the United States and other countries continuing to struggle with rolling outbreaks of . Accordingly, the full extent of the magnitude and duration of the negative impact to the Company’s business from the COVID-19 pandemic cannot be predicted with certainty. The Company considered the impact of COVID-19 on the assumptions and estimates used when preparing this Annual Report on Form 10-K and the accompanying consolidated financial statements. These assumptions and estimates may change as new events occur and additional information is obtained, and such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity.
Translation of Foreign Currencies	Translation of Foreign Currencies For all foreign operations, the functional currency is the local currency. Assets and liabilities of these operations are translated into U.S. dollars using the exchange rate in effect at the end of each reporting period. Income statement accounts Foreign currency gains and losses arising from the translation of intercompany receivables and intercompany payables with the Company’s international subsidiaries are recorded as a component of other expense, net, unless the receivable or payable is considered long-term in nature, in which case the foreign currency gains and losses are recorded as a component of accumulated other comprehensive loss.
Cash Equivalents	Cash Equivalents Cash and cash equivalents are defined as highly liquid investments with original maturities of three months or less. Cash balances may, at times, exceed insurable amounts. The Company believes it mitigates this risk by investing in or through major financial institutions. Cash includes balances due from third-party credit card companies.
Inventories	Inventories Inventories, which consist of finished goods, are stated at the lower of cost or net realizable value on a first-in, first-out basis, net of reserves for obsolescence and shrinkage.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. For financial reporting purposes, equipment is depreciated on the straight-line method over the estimated useful lives of the assets (3 to 10 years). Leasehold improvements are amortized on the straight-line method over the shorter of the term of the lease or the useful life of the related assets. Expenditures for new facilities and improvements that substantially extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When assets are retired or otherwise disposed of, the cost and related depreciation are removed from the accounts and any related gains or losses are included in income.
Impairment of Long Lived Assets	Impairment of Long Lived Assets The Company reviews long-lived assets, including amortizable intangible assets, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. In fiscal 2021, fiscal 2020 and fiscal 2019, the Company recorded impairment charges of $5, $62 and $307, respectively, related to internal-use computer software that was not expected to provide substantive service potential. In fiscal 2021, fiscal 2020 and fiscal 2019, the Company recorded impairment charges of $516, $1,310 and $0, respectively, related to property, plant and equipment that were expected to be disposed of before the end of their estimated useful lives.
Franchise Rights Acquired and Goodwill	Franchise Rights Acquired Finite-lived franchise rights acquired are amortized over the remaining contractual period, which is generally less than one year. Indefinite-lived franchise rights acquired are tested on an annual basis for impairment. In performing the impairment analysis for indefinite-lived franchise rights acquired, the fair value for franchise rights acquired is estimated using a discounted cash flow approach referred to as the hypothetical start-up approach for franchise rights related to the Company’s Workshops Workshops In its hypothetical start-up approach analysis for fiscal 2021, the Company assumed that the year of maturity was reached after 7 years. Subsequent to the year of maturity, the Company estimated future cash flows for the Workshops Workshops Goodwill In performing the impairment analysis for goodwill, the fair value for the Company’s reporting units is estimated using a discounted cash flow approach. This approach involves projecting future cash flows attributable to the reporting unit and discounting those estimated cash flows using an appropriate discount rate. The estimated fair value is then compared to the carrying value of the reporting unit. The Company has determined the appropriate reporting unit for purposes of assessing annual impairment to be the country for all reporting units. The net book values of goodwill in the United States, Canada and other countries as of the January 1, 2022 balance sheet date were $105,121, $42,409 and $9,844, respectively, totaling $157,374. The net book values of goodwill in the United States, Canada and other countries as of the January 2, 2021 balance sheet date were $102,968, $42,103 and $10,546, respectively, totaling $155,617. For all of the Company’s reporting units tested as of May 9, 2021, the Company estimated future cash flows by utilizing the historical debt-free cash flows (cash flows provided by operations less capital expenditures) attributable to that country and then applied expected future operating income growth rates for such country. The Company utilized operating income as the basis for measuring its potential growth because it believes it is the best indicator of the performance of its business. The Company then discounted the estimated future cash flows utilizing a discount rate which was calculated using the weighted-average cost of capital, which included the cost of equity and the cost of debt. Indefinite-Lived Franchise Rights Acquired and Goodwill Annual Impairment Test The Company reviews indefinite-lived intangible assets, including franchise rights acquired with indefinite lives, and goodwill for potential impairment on at least an annual basis or more often if events so require. The Company performed fair value impairment testing as of May 9, 2021 and May 3, 2020, each the first day of fiscal May, on its indefinite-lived intangible assets and goodwill. In performing its annual impairment analysis as of May 9, 2021 and May 3, 2020, the Company determined that the carrying amounts of its franchise rights acquired with indefinite lives units of account and goodwill reporting units did not exceed their respective fair values and, therefore, no impairment existed. When determining fair value, the Company utilizes various assumptions, including projections of future cash flows, growth rates and discount rates. A change in these underlying assumptions could cause a change in the results of the impairment assessments and, as such, could cause fair value to be less than the carrying amounts and result in an impairment of those assets. In the event such a result occurred, the Company would be required to record a corresponding charge, which would impact earnings. The Company would also be required to reduce the carrying amounts of the related assets on its balance sheet. Based on the results of the Company’s May 9, 2021 annual franchise rights acquired impairment analysis performed for all of its units of account, all units, except for New Zealand, had an estimated fair value at least 45% higher than the respective unit’s carrying amount. Collectively, these units of account represent 99.4% of the Company’s total franchise rights acquired as of the January 1, 2022 balance sheet date. Based on the results of the Company’s annual franchise rights acquired impairment test performed for its New Zealand unit of account, which holds 0.6% of the Company’s franchise rights acquired as of the January 1, 2022 balance sheet date, the estimated fair value of this unit of account exceeded its carrying value by approximately 10%. Accordingly, a change in the underlying assumptions for New Zealand may change the results of the impairment assessment and, as such, could result in an impairment of the franchise rights acquired related to New Zealand, for which the net book value was $4,840 Based on the results of the Company’s May 9, 2021 annual goodwill impairment test performed for all of its reporting units, there was significant headroom in the goodwill impairment analysis for those units, with the difference between the carrying value and the fair value exceeding 100%. Canada Indefinite-Lived Franchise Rights Acquired Interim Impairment Test The Company’s Canada unit of account had a net book value of $60,117, 7.7% of its franchise rights acquired as of the January 1, 2022 balance sheet date. Given the lower headroom in the May 9, 2021 annual franchise rights acquired impairment test for this unit relative to the other units of account and the decline in business performance through fiscal 2021 (which may continue into fiscal 2022), the Company performed an interim impairment analysis as of January 1, 2022. In this test, the estimated fair value of this unit of account exceeded its carrying value by approximately 3%. Therefore, the Company did not record an impairment for the Canada unit of account. Brazil Goodwill Impairment With respect to its Brazil reporting unit, during the first quarter of fiscal 2020, the Company made a strategic decision to shift to an exclusively Digital business in that country. The Company determined that this decision, together with the negative impact of COVID-19, the ongoing challenging economic environment in Brazil and its reduced expectations regarding the reporting unit’s future operating cash flows, required the Company to perform an interim goodwill impairment analysis. In performing this discounted cash flow analysis, the Company determined that the carrying amount of this reporting unit exceeded its fair value and as a result recorded an impairment charge of $3,665, which comprised the remaining balance of goodwill for this reporting unit. As it related to its goodwill impairment analysis for Brazil, the Company estimated future debt-free cash flows in contemplation of its growth strategies for that market. In developing these projections, the Company considered the growth strategies under the current market conditions in Brazil. The Company then discounted the estimated future cash flows utilizing a discount rate which was calculated using the weighted-average cost of capital, which included the cost of equity and the cost of debt.
Other Intangible Assets	Other Intangible Assets Other finite-lived intangible assets are amortized using the straight-line method over their estimated useful lives of 3 to 20 years. The Company expenses all software costs incurred during the preliminary project stage and capitalizes all internal and external direct costs of materials and services consumed in developing software once the development has reached the application development stage. Application development stage costs generally include software configuration, coding, installation to hardware and testing. These costs are amortized over their estimated useful life of 3 years for website development costs and from 3 to 5 years for all other software costs. All costs incurred for upgrades, maintenance and enhancements, including the cost of website content, which do not result in additional functionality, are expensed as incurred.
Revenue Recognition	Revenue Recognition Revenues are recognized when control of the promised services or goods is transferred to the Company’s customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those services or goods. The Company earns revenue from subscriptions for its digital products and by conducting workshops, for which it charges a fee, predominantly through commitment plans, as well as prepayment plans or the “pay-as-you-go” arrangement. The Company also earns revenue by selling consumer products online through its e-commerce platforms, at its studios, and through its trusted partners; collecting royalties related to licensing agreements; collecting royalties from franchisees; and publishing. Commitment plan revenues and prepaid workshop fees are recorded to revenue on a straight-line basis as control is transferred since these performance obligations are satisfied over time. “Digital Subscription Revenues,” consisting of the fees associated with subscriptions for the Company’s Digital products, including Digital 360 and Personal Coaching + Digital, are recognized on a straight-line basis as control is transferred since these performance obligations are satisfied over time. One-time Digital sign-up fees are considered immaterial in the context of the contract and the related revenue is amortized into revenue over the commitment period. “Workshops + Digital Fees” (formerly known as “Studio + Digital Fees”) Workshops The Company grants refunds in aggregate amounts that historically have not been material. Because the period of payment of the refund generally approximates the period revenue was originally recognized, refunds are recorded as a reduction of revenue over the same period. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The Company expenses sales commissions when incurred (amortization period would have been one year or less) and these expenses are recorded within selling, general and administrative expenses. The Company treats shipping and handling fees as fulfillment costs and not as a separate performance obligation, and as a result, any fees received from customers are included in the transaction price allocated to the performance obligation of providing goods with a corresponding amount accrued within cost of product sales and other for amounts paid to applicable carriers. Sales tax, value-added tax and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue.
Advertising Costs	Advertising Costs Advertising costs consist primarily of broadcast and digital media. All costs related to advertising are expensed in the period incurred, except for media production-related costs, which are expensed the first time the advertising takes place. Total advertising expenses for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 were $252,754, $248,473 and $235,826, respectively.
Income Taxes	Income Taxes Deferred income tax assets and liabilities result primarily from temporary differences between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which differences are expected to reverse. If it is more-likely-than-not that some portion of a deferred tax asset will not be realized, a valuation allowance is recognized. The Company considers historic levels of income, estimates of future taxable income and feasible tax planning strategies in assessing the need for a tax valuation allowance. The Company recognizes a benefit for uncertain tax positions when a tax position taken or expected to be taken in a tax return is more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company recognizes accrued interest and penalties associated with uncertain tax positions as part of the provision for income taxes on its consolidated statements of net income. In addition, assets and liabilities acquired in purchase business combinations are assigned their fair values and deferred taxes are provided for lower or higher tax bases.
Derivative Instruments and Hedging	Derivative Instruments and Hedging The Company is exposed to certain risks related to its ongoing business operations, primarily interest rate risk and foreign currency risk. Interest rate swaps were entered into to hedge a portion of the cash flow exposure associated with the Company’s variable-rate borrowings. The Company does not use any derivative instruments for trading or speculative purposes. The Company recognizes the fair value of all derivative instruments as either assets or liabilities on the balance sheet. The Company has designated and accounted for interest rate swaps as cash flow hedges of its variable-rate borrowings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive loss and reclassified into earnings in the periods during which the hedged transactions affect earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The fair value of the Company’s interest rate swaps is reported as a component of accumulated other comprehensive loss on its balance sheet. See Note 18 for a further discussion regarding the fair value of the Company’s interest rate swaps. The net effect of the interest payable and receivable under the Company’s effective interest rate swap is included in interest expense on its consolidated statements of net income.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs consist of fees paid by the Company as part of the establishment, exchange and/or modification of the Company’s long-term debt. Amortization expense for the fiscal years ended January 1, 2022, January 2, 2021 and December 28, 2019 was $6,136, $8,845 and $9,318, respectively.
