Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year ends on the last Saturday in September. Fiscal 2022, 2021 and 2020 ended on September 24, 2022, September 25, 2021 and September 26, 2020, respectively. Fiscal 2022, 2021 and 2020 were 52-week years. Fiscal 2023 will be a 53-week year.
Subsequent Events Consideration
The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that may require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized or unrecognized subsequent events recorded in the consolidated financial statements as of and for the year ended September 24, 2022.

Management’s Estimates and Uncertainties
The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make significant 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 revenues and expenses during the reporting periods. Significant estimates and assumptions by management affect the Company’s revenue recognition for multiple performance obligation arrangements, valuations, purchase price allocations and contingent consideration related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of intangible assets and goodwill, amortization methods and periods, accounts receivable reserves, inventory excess and obsolescence reserves, warranty reserves, certain accrued expenses, restructuring and other related charges, contingent liabilities, tax reserves, deferred tax rates and recoverability of the Company’s net deferred tax assets and related valuation allowances, and stock-based compensation.
Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.
The Company is subject to a number of risks similar to those of other companies of similar size in its industry, including supply chain constraints primarily related to electronic components, primarily semiconductor chips, dependence on third-party reimbursements to support the markets of the Company’s products, early stage of development of certain products, rapid technological changes, recoverability of long-lived assets (including intangible assets and goodwill), competition, stability of world financial markets, ability to obtain regulatory approvals, changes in the regulatory environment, limited number of suppliers, customer concentration, integration of acquisitions, substantial indebtedness, government regulations, management of international activities, protection of proprietary rights, patent and other litigation, dependence on contract manufacturers and dependence on key individuals.
Cash Equivalents
Cash equivalents are highly liquid investments with insignificant interest rate risk and maturities of three months or less at the time of acquisition.
Concentrations of Credit Risk
Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents, equity investments and trade accounts receivable. The Company invests its cash and cash equivalents with high credit quality financial institutions.
The Company’s customers are principally located in the U.S., Europe and Asia. The Company performs ongoing credit evaluations of the financial condition of its customers and generally does not require collateral. Although the Company is directly affected by the overall financial condition of the healthcare industry, as well as global economic conditions, management does not believe significant credit risk exists as of September 24, 2022. The Company generally has not experienced any material losses related to receivables from individual customers or groups of customers in the healthcare industry. The Company maintains an allowance for doubtful accounts based on accounts past due and historical collection experience.
There were no customers with a balance greater than 10% of accounts receivable as of September 24, 2022 and September 25, 2021. There were no customers that represented greater than 10% of consolidated revenues for fiscal years 2022, 2021 and 2020.
Concentration of Suppliers
The Company purchases certain components of its products from a single or small number of suppliers. A change in or loss of these suppliers could cause a delay in filling customer orders and a possible loss of sales, which could adversely affect results of operations.

Inventories
Inventories are valued at the lower of cost or market on a first-in, first-out basis. Work-in-process and finished goods inventories consist of materials, labor and manufacturing overhead. The valuation of inventory requires management to estimate excess and obsolete inventory. The Company employs a variety of methodologies to determine the net realizable value of its inventory. Provisions for excess and obsolete inventory are primarily based on management’s estimates of forecasted sales, usage levels and expiration dates, as applicable for certain disposable products. A significant change in the timing or level of demand for the Company’s products compared to forecasted amounts may result in recording additional charges for excess and obsolete inventory in the future. The Company records charges for excess and obsolete inventory within cost of product revenues.
Inventories consisted of the following:

Equipment under customer usage agreements primarily consists of diagnostic instruments located at customer sites but owned by the Company. Generally, the customer has the right to use the equipment for a period of time provided they meet certain agreed to conditions. The Company recovers the cost of providing the equipment from the sale of disposables, primarily assays, tests and handpieces. The depreciation costs associated with equipment under customer usage agreements are charged to cost of product revenues over the estimated useful life of the equipment. The costs to maintain the equipment in the field are charged to cost of product revenue as incurred.
In September 2020 and October 2020, the Company was awarded grants of $7.6 million and $119.3 million, respectively, from the Department of Defense Joint Acquisition Task Force ("DOD") to expand production capacity for the Company's two SARS-CoV-2 assays. These grants are specifically to fund capital equipment and labor investments to increase manufacturing capacity to enable the Company to provide a certain amount of COVID-19 tests per month for the U.S. market. The Company is accounting for the funds received under these grants as a reimbursement of the purchased capital equipment. The Company procures and pays for the capital equipment and necessary resources to build out its facility and construct the manufacturing lines to meet the requirements specified in the grant agreement. Subsequent to the Company paying for the capital equipment, the DOD will reimburse the Company upon it meeting certain requirements. However, the DOD retains title to assets purchased under the agreement, and title is transferred to the Company upon meeting certain milestones of the manufacturing efforts and obtaining approval from the DOD that the respective milestone has been met. As of September 24, 2022, the Company had $20.5 million of capital equipment that was awaiting approval from the DOD pending completion of the defined milestones. In fiscal 2022 and 2021, the Company received $75.0 million and $21.5 million, respectively, from the DOD for reimbursement of capital equipment, which has been recorded as a reduction of the cost basis of the purchased equipment. In addition, a portion of the DOD grant funds expenditures in connection with the project that don't qualify for capitalization and are recorded as a reduction to expenses, which was $7.6 million and $1.3 million in fiscal 2022 and 2021, respectively. Payments under these grants are subject to satisfaction of the conditions of the grants, including applicable governmental appropriations.
Long-Lived Assets
The Company reviews its long-lived assets, which includes property, plant and equipment and identifiable intangible assets (see below for discussion of intangible assets), for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in accordance with ASC 360-10-35-15, Property, Plant and Equipment—Impairment or Disposal of Long-Lived Assets (ASC 360). Recoverability of these assets is evaluated by comparing the carrying value of the assets to the undiscounted cash flows estimated to be generated by those assets over their remaining economic life. If the undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are considered impaired. The impairment loss is measured by comparing the fair value of the assets to their carrying value. Fair value is determined by either a quoted market price, if any, or a value determined by a discounted cash flow technique.
Business Combinations and Acquisition of Intangible Assets
The Company accounts for the acquisition of a business in accordance with ASC 805, Business Combinations (ASC 805). Amounts paid to acquire a business are allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. Contingent consideration not deemed to be linked to continuing employment is recorded at fair value on the date of acquisition. The value recorded is based on estimates of future financial projections under various potential scenarios using a Monte Carlo simulation. These cash flow projections are discounted with an appropriate risk adjusted rate. Each quarter until such contingent amounts are earned, the fair value of the liability is remeasured and adjusted as a component of operating expenses based on changes to the underlying assumptions. The estimates used to determine the fair value of the contingent consideration liability are subject to significant judgment and actual results are likely to differ from the amounts originally recorded. The Company determines the fair value of acquired intangible assets based on detailed valuations that use certain information and assumptions provided by management. The Company allocates any excess purchase price over the fair value of the net tangible and intangible assets acquired to goodwill.

The Company uses the income approach to determine the fair value of developed technology and in-process research and development ("IPR&D") acquired in a business combination. This approach determines fair value by estimating the after-tax cash flows attributable to the respective asset over its useful life and then discounting these after-tax cash flows back to a present value. The Company bases its revenue assumptions on estimates of relevant market sizes, expected market growth rates, expected trends in technology and expected product introductions by competitors. Developed technology represents patented and unpatented technology and know-how. The value of the in-process projects is based on the project's stage of completion, the complexity of the work completed as of the acquisition date, the projected costs to complete, the contribution of core technologies and other acquired assets, the expected introduction date, the estimated cash flows to be generated upon commercial release and the estimated useful life of the technology. The Company believes that the estimated developed technology and IPR&D amounts represent the fair value at the date of acquisition and do not exceed the amount a third-party would pay for the assets. The significant assumptions used to estimate the fair value of intangible assets include discount rates and certain assumptions that form the basis of the forecasted results specifically revenue growth rates. These significant assumptions are forward looking and could be affected by future economic and market conditions.
The Company also uses the income approach, as described above, to determine the estimated fair value of certain other identifiable intangible assets including customer relationships, and trade names. Customer relationships represent established relationships with customers, which provide a ready channel for the sale of additional products and services. Trade names represent acquired company and product names.
Intangible Assets and Goodwill
Intangible Assets
Intangible assets are initially recorded at fair value and stated net of accumulated amortization and impairments. The Company amortizes its intangible assets that have finite lives using either the straight-line method, or if reliably determinable, based on the pattern in which the economic benefit of the asset is expected to be utilized. Amortization is recorded over the estimated useful lives ranging from 5 to 30 years. The Company evaluates the recoverability of its definite lived intangible assets whenever events or changes in circumstances or business conditions indicate that the carrying value of these assets may not be recoverable based on expectations of future undiscounted cash flows for each asset group. If the carrying value of an asset or asset group exceeds its undiscounted cash flows, the Company estimates the fair value of the assets, generally utilizing a discounted cash flow analysis based on the present value of after-tax cash flows to be generated by the assets using a risk-adjusted discount rate. To estimate the fair value of the assets, the Company uses market participant assumptions pursuant to ASC 820, Fair Value Measurements.
Indefinite lived intangible assets, such as IPR&D assets, are initially recorded at fair value and are required to be tested for impairment annually, or more frequently if indicators of impairment are present. The Company’s annual impairment test date is as of the first day of its fourth quarter.

During the fourth quarter of fiscal 2022, the Company performed its annual impairment test of its only IPR&D intangible asset, which was acquired in the Mobidiag Oy acquisition. The Company determined the fair value of the asset utilizing a DCF model and recorded a $27.7 million impairment charge. The reduction in fair value was due to an increase in the discount rate from higher interest rates, a reduction in forecasted revenues and timing of completing the project. During the fourth quarter of fiscal 2022, the Company identified a certain product line associated with the Focal Therapeutics, Inc. acquisition that would no longer be commercially sold. As a result, the Company recorded an impairment charge to write-off a developed technology asset of $8.2 million. During the third quarter of fiscal 2022, the Company identified certain product lines associated with the Faxitron Bioptics, LLC acquisition that would no longer be commercially sold. As a result, the Company recorded an impairment charge to write-off the developed technology assets of $9.2 million. During the first quarter of fiscal 2022, the Company acquired Bolder Surgical Holdings, Inc. and recorded $73.6 million of developed technology, $21.7 million of customer relationships and $1.4 million of trade names based on its preliminary purchase accounting.
During the third quarter of fiscal 2021, the Company acquired Mobidiag and recorded $285.0 million of developed technology, $74.0 million of in-process research and development, $20.9 million of customer relationships and $20.0 million of trade names. During the second quarter of fiscal 2021, the Company acquired Biotheranostics, Inc. and recorded $160.3 million of developed technology and $2.1 million of trade names. During the second quarter of fiscal 2021, the Company acquired Diagenode SA and recorded $69.8 million of developed technology and $9.2 million of customer relationships. During the second quarter of fiscal 2021, the Company acquired Somatex Medical Technologies GmbH and recorded $38.0 million of developed technology, $1.2 million of customer relationships and $0.9 million of trade names.
Amortization expense related to developed technology is classified as cost of product revenues—amortization of intangible assets. Amortization expense related to customer relationships, and trade names is classified as a component of amortization of intangible assets within operating expenses.
The estimated amortization expense at September 24, 2022 for each of the five succeeding fiscal years was as follows:
 
Fiscal 2023$234.8 
Fiscal 2024$221.1 
Fiscal 2025$207.4 
Fiscal 2026$175.8 
Fiscal 2027$84.6 
Goodwill
In accordance with ASC 350, Intangibles—Goodwill and Other (ASC 350), the Company tests goodwill for impairment annually at the reporting unit level and between annual tests if events and circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. Events that could indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate, operational performance of the business or key personnel, and an adverse action or assessment by a regulator.
In performing the impairment test, the Company utilizes the single-step approach prescribed under Accounting Standards Update No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). This approach requires a comparison of the carrying value of each reporting unit to its estimated fair value and to the extent the carrying value exceeds the fair value a charge is recorded up to the amount of goodwill in the reporting unit. To estimate the fair value of its reporting units, the Company primarily utilizes the income approach. The income approach is based on a DCF analysis and calculates the fair value by estimating the after-tax cash flows attributable to a reporting unit and then discounting the after-tax cash flows to present value using a risk-adjusted discount rate. Assumptions used in the DCF require significant judgment, including judgment about appropriate discount rates and terminal values, growth rates, and the amount and timing of expected future cash flows. The forecasted cash flows are based on the Company’s most recent budget and strategic plan and for years beyond this period, the Company’s estimates are based on assumed growth rates expected as of the measurement date. The Company believes its assumptions are consistent with the plans and estimates used to manage the underlying businesses. The discount rates used are intended to reflect the risks inherent in future cash flow projections and are based on estimates of the weighted-average cost of capital (“WACC”) of market participants. The market approach considers comparable market data based on multiples of revenue or earnings before interest, taxes, depreciation and amortization (“EBITDA”) and is primarily used as a corroborative analysis to the results of the DCF analysis. The Company believes its assumptions used to determine the fair value of its reporting units are reasonable. If different assumptions were used, particularly with respect to forecasted cash flows, terminal values, WACCs, or market multiples, different estimates of fair value may result and there could be the potential that an impairment charge could result. Actual operating results and the related cash flows of the reporting units could differ from the estimated operating results and related cash flows.
The Company conducted its fiscal 2022 impairment test for its reporting units on the first day of the fourth quarter, and as noted above used DCF and market approaches to estimate the fair value of its reporting units as of June 26, 2022, and ultimately used the fair value determined by the DCF approach in making its impairment test conclusions. As a result of completing this analysis, all of the Company's reporting units had fair values exceeding their carrying values.
At September 24, 2022, the Company believes that its reporting units, with goodwill aggregating $3.2 billion, were not at risk of failing the goodwill impairment test based on its current forecasts and qualitative assessment.
The Company conducted its fiscal 2021 and 2020 impairment tests for its reporting units on the first day of the fourth quarter of its respective fiscal year, and as noted above used DCF and market approaches to estimate the fair value of its reporting units as of the measurement date, and ultimately used the fair value determined by the DCF approach in making its impairment test conclusions. The Company believes it used reasonable estimates and assumptions about future revenue, cost projections, cash flows, market multiples and discount rates as of each measurement date. As a result of completing these analyses, all of the Company's reporting units had fair values exceeding their carrying values.

The right of use assets were recorded in connection with the adoption of ASC 842, Leases, and pertains to operating leases. Life insurance contracts were purchased in connection with the Company’s Nonqualified Deferred Compensation Plan (“DCP”) and are recorded at their cash surrender value (see Note 12 for further discussion).
Research and Software Development Costs
Costs incurred for the research and development of the Company’s products are expensed as incurred. Nonrefundable advance payments for goods or services to be received in the future by the Company for use in research and development activities are deferred. The deferred costs are expensed as the related goods are delivered or the services are performed.
The Company accounts for the development costs of software embedded in the Company’s products in accordance with ASC 985, Software. Costs incurred in the research, design and development of software embedded in products to be sold to customers are charged to expense until technological feasibility of the ultimate product to be sold is established. The Company’s policy is that technological feasibility is achieved when a working model, with the key features and functions of the product, is available for customer testing. Software development costs incurred after the establishment of technological feasibility and until the product is available for general release are capitalized, provided recoverability is reasonably assured. Capitalized software development costs are amortized over their estimated useful life and recorded within cost of revenues - product.
Foreign Currency Translation
The financial statements of the Company’s foreign subsidiaries are translated in accordance with ASC 830, Foreign Currency Matters. The reporting currency for the Company is the U.S. dollar. The functional currency of the Company’s foreign subsidiaries is determined based on the guidance in ASC 830. The majority of the Company's foreign subsidiaries' functional currency is the applicable local currency, although certain of the Company's foreign subsidiaries' functional currency is the U.S. dollar based on the nature of their operations or functions. Assets and liabilities of subsidiaries whose functional currency is the local currency are translated at the exchange rate in effect at each balance sheet date. Before translation, the Company re-measures foreign currency denominated assets and liabilities, including inter-company accounts receivable and payable, into the functional currency of the respective entity, resulting in unrealized gains or losses recorded in other income (expense), net in the Consolidated Statements of Income. Revenues and expenses are translated using average exchange rates during the respective period. Foreign currency translation adjustments are accumulated as a component of other comprehensive income (loss), which is a separate component of stockholders’ equity. Gains and losses arising from transactions denominated in foreign currencies are included in other income (expense), net in the Consolidated Statements of Income. During fiscal years 2022, 2021 and 2020, the Company recorded net foreign exchange gains (losses) of $48.5 million, $(15.1) million, and $3.4 million, respectively.
Accumulated Other Comprehensive Income (Loss)

Derivatives
Interest Rate Risk - Cash Flow Hedge
The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages its exposure to some of its interest rate risk through the use of interest rate swaps, which are derivative financial instruments. The Company does not use derivatives for speculative purposes. For a derivative that is designated as a cash flow hedge, changes in the fair value of the derivative are recognized in accumulated other comprehensive income ("AOCI") to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings.
During fiscal 2018, the Company entered into separate interest rate cap agreements with multiple counter-parties to mitigate the interest rate volatility associated with the variable interest rate on its amounts borrowed under the term loan feature of its credit facilities (see Note 7). Interest rate cap agreements provide the right to receive cash if the reference interest rate rises above a contractual rate. During fiscal 2019, the Company entered into additional separate interest rate cap agreements with multiple counter-parties to extend the expiration date of its hedges by an additional year.
The critical terms of the interest rate caps were designed to mirror the terms of the Company’s LIBOR-based borrowings under its Credit Agreement, that has been amended multiple times, and therefore were highly effective at offsetting the cash flows being hedged. The Company designated these derivatives as cash flow hedges of the variability of the LIBOR-based interest payments on $1.0 billion of principal, which ended on December 27, 2019 (the first quarter of fiscal 2020) for the contracts entered into in fiscal 2018, and on December 23, 2020 (the first quarter of fiscal 2021) for the interest rate cap agreements entered into in fiscal 2019.
During fiscal 2021 and 2020, interest expense of $0.5 million and $2.3 million, respectively, was reclassified from AOCI to the Company's Consolidated Statements of Income related to the interest rate cap agreements. The last interest rate cap agreement matured as of December 26, 2020.
In fiscal 2019, in order to hedge a portion of its variable rate debt, the Company entered into an interest rate swap contract with an effective date of December 23, 2020 and a termination date of December 17, 2023. On August 25, 2022, the interest rate swap agreement (consistent with the Company's Credit Agreement; see Note 7) was restructured to convert the benchmark interest rate from LIBOR to the SOFR rate effective September 23, 2022 with a termination date of December 17, 2023. The Company applied the practical and optional expedients in ASC 848, Reference Rate Reform, in evaluating the impact of modifying the contract, which resulted in no change to the accounting for this derivative contract. The notional amount of this swap is $1.0 billion. The restructured interest rate swap effectively fixes the SOFR component of the variable interest rate on $1.0 billion of the notional amount under the 2021 Credit Agreement at 1.23%. The critical terms of the restructured interest rate swap are designed to mirror the terms of the Company’s SOFR-based borrowings under its credit agreement and therefore are highly effective at offsetting the cash flows being hedged. The Company designated this derivative as a cash flow hedge of the variability of the SOFR-based interest payments on $1.0 billion of principal. Therefore, changes in the fair value of the swap are recorded in AOCI and net of taxes were a gain of $44.0 million, a gain of $9.4 million and a loss of $27.6 million for fiscal years 2022, 2021, and 2020, respectively. The fair value of this derivative was in an asset position of $38.9 million as of September 24, 2022.
Forward Foreign Currency Contracts and Foreign Currency Option Contracts
The Company enters into forward foreign currency exchange contracts and foreign currency option contracts to mitigate certain operational exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company's cash and operations that are denominated in currencies other than the U.S. dollar, primarily the Euro, the UK Pound, the Australian dollar, the Canadian dollar, the Chinese Yuan and the Japanese Yen. These foreign currency exchange contracts are entered into to support transactions made in the ordinary course of business and are not speculative in nature. The contracts are generally for periods of one year or less. The Company did not elect hedge accounting for these contracts; however, the Company may seek to apply hedge accounting in future scenarios. The change in the fair value of these contracts is recognized directly in earnings as a component of other income, net.

Trade Receivables and Allowance for Credit Losses
Effective September 27, 2020, the Company adopted ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. The expected credit losses are developed using an estimated loss rate method that considers historical collection experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The estimated loss rates are applied to trade receivables with similar risk characteristics such as the length of time the balance has been outstanding and the location of the customer. In certain instances, the Company may identify individual trade receivable assets that do not share risk characteristics with other trade receivables, in which case the Company records its expected credit losses on an individual asset basis. For example, potential adverse changes to customer liquidity from new macroeconomic events, such as the COVID-19 pandemic, must be taken into consideration. To date, the Company has not experienced significant customer payment defaults, or identified other significant collectability concerns as a result of the COVID-19 pandemic. In connection with assessing credit losses for individual trade receivable assets, the Company considers significant factors relevant to collectability including those specific to the customer such as bankruptcy, length of time an account is outstanding, and the liquidity and financial position of the customer. If a trade receivable asset is evaluated on an individual basis, the Company excludes those assets from the portfolios of trade receivables evaluated on a collective basis.

Cost of Service and Other Revenues
Cost of service and other revenues primarily represents payroll and related costs associated with the Company’s professional services, employees, consultants, infrastructure costs and overhead allocations, including depreciation, rent and materials consumed in providing the service.
Stock-Based Compensation
The Company accounts for share-based payments in accordance with ASC 718, Stock Compensation (ASC 718). As such, all share-based payments to employees, including grants of stock options, restricted stock units, performance stock units and market stock units and shares issued under the Company’s employee stock purchase plan, are recognized in the Consolidated Statements of Income based on their fair values on the date of grant. In addition, all excess tax benefits and deficiencies are recognized as a component of the provision for income taxes on a discrete basis in the period in which the equity awards vest and/or are settled.
Net Income Per Share
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average number of common shares and the dilutive effect of potential future issuances of common stock from outstanding stock options and restricted stock units for the period outstanding determined by applying the treasury stock method. In accordance with ASC 718, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of in-the-money stock options and restricted stock units. This results in the assumed buyback of additional shares, thereby reducing the dilutive impact of equity awards.
A reconciliation of basic and diluted share amounts for fiscal 2022, 2021, and 2020 was as follows:
September 24, 2022September 25, 2021September 26, 2020

Product Warranties
The Company generally offers a one-year warranty for its products. The Company provides for the estimated cost of product warranties at the time product revenue is recognized. Factors that affect the Company’s warranty reserves include the number of units sold, historical and anticipated rates of warranty repairs and the cost per repair. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary.
Product warranty activity for fiscal 2022 and 2021 was as follows:

Advertising Costs
Advertising costs are charged to operations as incurred. The Company does not have any direct-response advertising. Advertising costs, which include trade shows and conventions, were approximately $78.1 million, $9.8 million and $15.6 million for fiscal 2022, 2021 and 2020, respectively, and were included in selling and marketing expense in the Consolidated Statements of Income. The increase in advertising costs in fiscal 2022 was primarily due to the Company's agreement to be a sponsor of the Women's Tennis Association and the production and running of its Super Bowl commercial.

New Accounting Pronouncements
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. The FASB issued this Update as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, and are applicable to the Company in fiscal 2022. The adoption of ASU No. 2019-12 did not have a material impact on the Company's consolidated financial position and results of operations.
In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The FASB issued this Update to clarify certain interactions between the guidance to account for certain equity securities under Topic 321, the guidance to account for investments under the equity method of accounting in Topic 323, and the guidance in Topic 815. This update could change how an entity accounts for an equity security under the measurement alternative or a forward contract or purchased option to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting or the fair value option in accordance with Topic 825, Financial Instruments. For entities that have adopted the amendments in Update 2020-01, the updated guidance is effective for annual periods beginning after December 15, 2020, and is applicable to the Company in fiscal 2022. The adoption of ASU No. 2020-01 did not have a material impact on the Company's consolidated financial position and results of operations.
In January 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848). The FASB issued this Update as optional guidance for a limited period of time to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. This update will provide optional expedients and exceptions for applying GAAP to only contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be
discontinued because of reference rate reform. For entities that have adopted the amendments in Update 2020-04, the updated guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted ASU 2020-04 in the first quarter of fiscal 2022, which did not have a material impact on the Company's consolidated financial position and results of operations.
In January 2021, FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) Scope. The FASB issued this Update in response to stakeholder concerns about potential diversity in practice. The FASB decided to clarify the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. This update provides optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to only contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. For entities that have adopted the amendments in Update 2021-01, the updated guidance is effective for all entities immediately as of January 2021. The Company adopted ASU 2021-01 in the first quarter of fiscal 2022, which did not have a material impact on the Company's consolidated financial position and results of operations.
In May 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842), Lessors - Certain Leases with Variable Lease Payments. This Update addresses an issue related to a lessor's accounting for certain leases with variable lease payments. The amendments in this Update affect lessors with lease contracts that (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as a sales-type lease or a direct financing lease. The Company adopted the amendments in ASU No. 2021-05 in the first quarter of fiscal 2022, which did not have a material effect on the Company's consolidated financial statements.
