Accounting Policies [Abstract]

Basis of Presentation and Preparation

Basis of Presentation and Preparation—The consolidated financial statements of Fortinet and its subsidiaries (collectively, the “Company,” “we,” “us” or “our”) have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). We consolidate all legal entities in which we have an absolute controlling financial interest. All intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

Use of Estimates—The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Such management estimates include, but are not limited to, the determination of contingent liabilities, the determination of our ability to exercise control or significant influence over our investee, the standalone selling price for our products and services, the period of benefit for deferred contract costs for commissions, stock-based compensation, inventory valuation, the fair value of tangible and intangible assets acquired and liabilities assumed in business combinations, the measurement of liabilities for uncertain tax positions and deferred tax assets and liabilities, the assessment of recoverability of our goodwill and other long-lived assets, measurement of non-marketable equity securities and the determination of sales returns reserves. We base our estimates on historical experience and also on assumptions that we believe are reasonable. Actual results could differ materially from those estimates.

Concentration Risk

Concentration Risk—Financial instruments that subject us to concentrations of credit risk consist primarily of cash, cash equivalents, short-term and long-term investments, marketable equity securities and accounts receivable. Our cash balances are maintained as deposits with various large financial institutions in the United States and around the world. Balances in the United States typically exceed the amount of insurance provided on such deposits. We maintain our cash equivalents and investments in money market funds, corporate debt securities, U.S. government and agency securities, commercial paper, certificates of deposit and term deposits and municipal bonds with major financial institutions that our management believes are financially sound.

Our accounts receivable are derived from our customers in various geographic locations. We perform ongoing credit evaluations of our customers. We generally do not require collateral on accounts receivable, and we maintain reserves for estimated credit losses. As of December 31, 2021, Exclusive Networks Group (“Exclusive”), TD Synnex and Ingram Micro Inc. (“Ingram Micro”) accounted for 33%, 13% and 13% of total net accounts receivable, respectively. As of December 31, 2020, Exclusive and Ingram Micro accounted for 34% and 11% of total net accounts receivable, respectively.

During 2021, Exclusive and Ingram Micro accounted for 31% and 12% of total revenue, respectively. During 2020, Exclusive and Ingram Micro accounted for 30% and 10% of total revenue, respectively. During 2019, Exclusive and Ingram Micro accounted for 31% and 11% of total revenue, respectively.

We rely on a small number of manufacturing partners, primarily in Taiwan, to manufacture our products, and some of the chips and other components of our products used by the contract manufacturers are available from limited or sole sources of supply. Our proprietary Application-Specific Integrated Circuits are built by contract manufacturers located in Japan and Taiwan; other integrated circuits are provided by other chip manufacturers and are currently in short supply.

Financial Instruments and Fair Value

Financial Instruments and Fair Value—We define fair value as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Due to their short-term nature, the carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, and accrued payroll and compensation.

Comprehensive Income

Comprehensive Income—Comprehensive income includes certain changes in equity from non-owner sources that are excluded from net income, specifically, cumulative foreign currency translation adjustments, unrealized gains and losses on available-for-sale investments and the related tax impact.

Foreign Currency and Transaction Gains and Losses

Foreign Currency and Transaction Gains and Losses—The functional currency for most of our foreign subsidiaries is the U.S. dollar. For our international subsidiary whose functional currency is the local currency, we translate the financial statements of these subsidiaries to U.S. dollars using the exchange rates in effect at the balance sheet dates for assets and liabilities, and average monthly rates of exchange for revenues, costs, and expenses. We record translation gains and losses in accumulated other comprehensive income as a component of equity.

Cash, Cash Equivalents and Available-for-sale Investments

Cash and Cash Equivalents—We consider all highly liquid investments, purchased with original maturities of three months or less, to be cash equivalents. Cash and cash equivalents consist of balances with banks and highly liquid investments in commercial paper, corporate debt, term deposits and money market funds.

Available-for-Sale Investments—We hold investment grade securities consisting of commercial paper, corporate debt securities, U.S. government and agency securities, certificates of deposit and term deposits, money market funds and municipal bonds that our management believes are financially sound. We classify our investments as available-for-sale (“AFS”) at the time of purchase, since it is our intent that these investments are available for current operations. Investments with original maturities greater than three months with a remaining maturity of less than one year from the consolidated balance sheet date are classified as short-term investments. Investments with remaining maturities greater than one year from the consolidated balance sheet date are classified as long-term investments.

Our AFS investments in debt securities are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) in consolidated statements of equity. AFS debt securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of that difference, if any, is caused by expected credit losses. An investment is impaired if the fair value of the investment is less than its cost. If the fair value of an investment is less than its amortized cost basis at the balance sheet date and if we do not intend to sell the investment, we consider available evidence to assess whether it is more likely than not that we will be required to sell the investment before the recovery of its amortized cost basis. We consult with our investment managers and consider available quantitative and qualitative evidence in evaluating, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and our ability to hold the investment. Once an impairment is determined to be attributable to credit-related factors, allowance for credit losses (i.e., the credit loss component) on AFS debt securities is recognized as credit loss expense, a charge in other expense—net, on our consolidated statements of income, and any remaining unrealized losses (i.e., the non-credit loss component), net of taxes, are included in accumulated other comprehensive income (loss) on our consolidated statements of equity.

Prior to 2020, we followed the guidance in Accounting Standards Codification (“ASC”) 320 Investments—Debt and Equity Securities in determining whether unrealized losses were other than temporary. In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-13—Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Topic 326”). We adopted Topic 326 on January 1, 2020, and now consider whether unrealized losses have resulted from a credit loss or other factors. The unrealized losses on our AFS debt securities as of December 31, 2021 and 2020 were caused by fluctuations in market value and interest rates as a result of the market conditions. We concluded that an allowance for credit losses was unnecessary as of December 31, 2021 and 2020 and that the unrealized losses as of December 31, 2019 were temporary because (i) the decline in market value was attributable to changes in market conditions and not credit quality, and (ii) we concluded that neither do we intend to sell nor is it more likely than not that we will be required to sell these investments prior to recovery of their amortized cost basis. As a result, we had no credit losses recorded for the year ended December 31, 2021 and 2020, and there was no impairment charge for any unrealized losses in 2019.

We determine realized gains or losses on sale of AFS debt securities using specific identification method to determine the cost basis of investments sold and record such gains or losses as other income (expense)-net on the consolidated statements of income. We have elected to not record an allowance for credit losses for accrued interest for AFS investments in debt

securities and will reverse the accrued interest against interest income in the period in which we determine the accrued interest to be uncollectible.

Marketable Equity Securities

Marketable Equity Securities—Our marketable equity investments with readily determinable fair values are accounted for at fair value through net income. Realized gains and losses on these securities are reported in other income (expense)-net, and are determined using the specific identification method.

Investments in privately held companies

Investments in privately held companies—Our investments in privately held companies consist of investments in common stock or in-substance common stock of entities. Certain of these investments provide us with the ability to exercise significant influence over the investee, but not an absolute controlling financial interest. These investments are accounted for under the equity method of accounting and were initially recorded at cost. Subsequently, we recognize our proportionate share of the entities’ net income or loss and the amortization of any basis differences as gain or loss from equity method investments in the consolidated statements of income and as an adjustment to the investment balance. We record our proportionate share of the results of equity method investments on a three-month lag basis. We evaluate our equity method investments at the end of each reporting period to determine whether events or changes in business circumstances indicate that the carrying value of the investment may not be recoverable. As of December 31, 2021, our investment in Linksys Holdings, Inc. (“Linksys”) was our only equity method investment and was recorded in other assets. Our remaining investments in privately held companies are recorded at cost and are not material.

Accounts receivable

Accounts receivable—Trade accounts receivable are recorded at the invoiced amount. On January 1, 2020, we adopted Topic 326, which provides guidance on how to measure credit losses on financial instruments, including accounts receivable. Prior to our adoption of Topic 326, our accounts receivable balance was reduced by an allowance for doubtful accounts that we determined based on our assessment of the collectability of customer accounts. Under Topic 326, our accounts receivable balance is reduced by an allowance for expected credit losses. We measure expected credit losses of accounts receivable on a collective (pooled) basis, aggregating accounts receivable that are either current or no more than 60 days past due, and aggregating accounts receivable that are more than 60 days past due. We apply a credit-loss percentage to each of the pools that is based on our historical credit losses. We review whether each of our significant accounts receivable that is more than 60 days past due continues to exhibit similar risk characteristics with the other accounts receivable in the pool. If we determine that it does not, we evaluate it for expected credit losses on an individual basis. We further consider collectability trends for the allowance for credit losses based on our assessment of various factors, including credit quality of our customers, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect our ability to collect from our customers. Expected credit losses are recorded as general and administrative expenses on our consolidated statements of income.

Inventory

Inventory—Inventory is recorded at the lower of cost or net realizable value. Cost is computed using the first-in, first-out method. In assessing the ultimate recoverability of inventory, we make estimates regarding future customer demand, the timing of new product introductions, economic trends and market conditions. If the actual product demand is significantly lower than forecasted, we could be required to record inventory write-downs which would be charged to cost of product revenue.

Property and Equipment

Property and Equipment—Property and equipment are stated at cost less accumulated depreciation. We do not depreciate the allocated cost of land. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:

			Estimated Useful Lives
Building and building improvements			2 to 40 years
Computer equipment and software			1 to 7 years
Evaluation units			1 year
Furniture and fixtures			3 to 8 years
Leasehold improvements			Shorter of useful life or lease term

Business Combinations

Business Combinations—We include the results of operations of the businesses that we acquire as of the respective dates of acquisition. We allocate the fair value of the purchase price of our business acquisitions to the tangible and intangible assets acquired and liabilities assumed, based on their estimated fair values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Our estimates and assumptions are subject to change and we often continue to gather additional information throughout the measurement period, which is up to 12 months after the acquisition date, and if we make changes to the amounts recorded, such amounts are recorded in the period in which they are identified.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets—We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible assets, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of those assets, we record an impairment charge in the period in which we make the determination. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Goodwill

Goodwill—Goodwill represents the excess of purchase consideration over the estimated fair value of net assets of businesses acquired in a business combination. Goodwill acquired in a business combination is not amortized, but instead tested for impairment at least annually during the fourth quarter, or sooner when circumstances indicate an impairment may exist. We perform a qualitative assessment in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. Then we perform a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. Any excess in the carrying value of a reporting unit over its fair value is recognized as an impairment loss in goodwill, limited to the total amount of goodwill allocated to that reporting unit.

We performed our annual goodwill impairment analysis and did not identify any impairment indicators as a result of the review. As of December 31, 2021, we had one reporting unit.

Other Intangible Assets

Other Intangible Assets—Intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed using the straight-line or accelerated method over the estimated economic lives of the assets, which range from one to ten years.

Income Taxes

Income Taxes—We record income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets and liabilities are expected to be realized or settled. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.

As part of the process of preparing our consolidated financial statements, we are required to estimate our taxes in each of the jurisdictions in which we operate. We estimate actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets, which are included in our consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in our consolidated statements of income become deductible expenses under applicable income tax laws, or loss or credit carryforwards are utilized.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We continue to assess the need for a valuation allowance on the deferred tax assets by evaluating both positive and negative evidence that may exist. Any adjustment to the valuation allowance on deferred tax assets would be recorded in the consolidated statements of income for the period that the adjustment is determined to be required.

We recognize tax benefits from an uncertain tax position only if it is more likely than not, based on the technical merits of the position, that the tax position will be sustained on examination by the tax authorities. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

We have elected to account for Global Intangible Low-Taxed Income (“GILTI”), which was introduced in the 2017 Tax Act, as a current period expense.

Stock-Based Compensation

Stock-Based Compensation—The fair value of restricted stock units (“RSUs”) is based on the closing market price of our common stock on the date of grant. We have elected to use the Black-Scholes-Merton (“Black-Scholes”) pricing model to determine the fair value of our employee stock options and our equity incentive plans. Stock-based compensation expense is amortized on a straight-line basis over the service period. We account for forfeitures of all stock-based payment awards when they occur.

Leases

Leases—We determine if an arrangement is a lease at inception. The right-of-use (“ROU”) assets and the short and long-term lease liabilities from our operating leases are included in other assets, accrued liabilities and other liabilities in our consolidated balance sheets, respectively. The corresponding assets and, the short and long-term lease liabilities from our finance leases are included in property and equipment, accrued liabilities and other liabilities in our consolidated balance sheets, respectively.

The ROU assets represent our right to use an underlying asset for the lease term. Lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and therefore we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using indicative bank borrowing rates, adjusted for various factors including level of collateralization, term and currency to align with the terms of a lease. The operating lease ROU asset also includes any lease prepayments and initial direct costs, net of lease incentives. Certain leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.

Lease expense for lease payments for our operating leases is recognized on a straight-line basis over the term of the lease. We begin recognizing rent expense on the date that a lessor makes an underlying asset that is subject to the lease available for our use. For our finance leases, we recognize amortization expense from the amortization of the corresponding assets and interest expense on the related lease liabilities.

Advertising Expense

Advertising Expense—Advertising costs are expensed when incurred and are included in operating expenses in the accompanying consolidated statements of income. Our advertising expenses were not material for any periods presented.

Research and Development Costs and Software Development Costs

Research and Development Costs—Research and development costs are expensed as incurred.

Software Development Costs—The costs to develop software that is marketed have not been capitalized as we believe our current software development process is essentially completed concurrently with the establishment of technological feasibility. Such costs are expensed as incurred and included in research and development in our consolidated statements of income.

The costs to obtain or develop software for internal use are capitalized based on qualifying criteria, which includes a determination of whether such costs are incurred during the application development stage. Such costs are amortized over the software’s estimated useful life.

Deferred Contract Costs

Deferred Contract Costs and Commission Expense—Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. We recognize sales commissions expenses related to product sales upfront while sales commissions expenses for service contracts are deferred as deferred contract costs in the consolidated balance sheets and amortized over the applicable amortization period. Commission costs for initial contracts that are not commensurate with commissions on renewal contracts are amortized on a straight-line basis over the period of benefit, which we have determined to be five years and which is typically longer than the initial contract term. The amortization of deferred contract costs is included in sales and marketing expense in our consolidated statements of income.

Deferred Revenue

Deferred Revenue—Deferred revenue consists of amounts that have been invoiced but that have not yet been recognized as revenue. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as non-current deferred revenue. The majority of deferred revenue is comprised of security subscription and technical support services which are invoiced upfront and delivered over 12 months or longer.

Revenue Recognition

Revenue Recognition—Our revenue consists of product and service revenue. Revenues are recognized when control of these goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We determine revenue recognition through the following steps:

•identification of a contract or contracts with a customer;

•identification of the performance obligations in a contract, including evaluation of performance obligations and evaluating the distinct goods or services in a contract;

•determination of a transaction price;

•allocation of a transaction price to the performance obligations in a contract; and

•recognition of revenue when, or as, we satisfy a performance obligation.

We derive a majority of product sales from our FortiGate hardware and virtual machine products which include a broad set of built-in security and networking features and functionalities, including firewall, next-generation firewall, secure web gateway, secure sockets layer (“SSL”) inspection, software-defined wide-area network, intrusion prevention, SSL data leak prevention, virtual private network, switch and wireless controller and wide area network edge.

We recognize product revenue upon shipment when control of the promised goods is transferred to the customer. Our term software licenses represent multiple performance obligations, which include software licenses and software support services where the term licenses are recognized upfront upon transfer of control, with the associated software support services recognized ratably over the contract term as services and software updates are provided.

Service revenue relates to sales of our FortiGuard security subscription, FortiCare technical support services and other services. Our typical subscription and contractual support term is one to five years. We generally recognize revenue from these services ratably over the support period because of continuous transfer of control to the customer. We also generate a small portion of our revenue from other services consisting of professional services, training and software-as-a-service (“SaaS”) which is either hosted by us or provided through cloud-providers. We recognize revenue from professional and training services as the services are provided. We recognize revenue from SaaS as the subscription service is delivered over the term, which is typically one year, or on a monthly usage basis. To date, SaaS revenue has not represented a significant percentage of our total revenue.

Our sales contracts typically contain multiple deliverables, such as hardware, software license, security subscription, technical support services and other services, which are generally capable of being distinct and accounted for as separate performance obligations. Our hardware and software licenses have significant standalone functionalities and capabilities. Accordingly, the hardware and software licenses are distinct from the security subscription and technical support services, as a customer can benefit from the product without the services and the services are separately identifiable within a contract. We allocate a transaction price to each performance obligation based on relative standalone selling price. We establish standalone selling price using the prices charged for a deliverable when sold separately. If not observable through past transactions, we determine standalone selling price by considering multiple historical factors including, but not limited to, cost of products, gross margin objectives, pricing practices, geographies and the term of a service contract. Revenue is reported net of sales tax.

In certain circumstances, our contracts include provisions for sales rebates and other customer incentive programs. Additionally, in limited circumstances, we may permit end-customers, distributors and resellers to return our products, subject to varying limitations, for a refund within a reasonably short period from the date of purchase. These amounts are accounted for as variable consideration that can decrease the transaction price. We estimate variable consideration using the expected-value method based on the most likely amounts to which we expect our customers to be entitled. We include estimated amounts in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimate for refund liabilities, which include sales returns reserve and customer rebates, was $49.2 million and $43.0 million as of December 31, 2021 and 2020, respectively, and is included in current liabilities in our consolidated balance sheet.

We generally invoice at the time of our sale for the total price of the hardware, software licenses, security and technical support and other services. Standard payment terms are generally no more than 60 days, though we continue to offer extended payment terms to certain distributors. We also invoice certain services on a monthly basis. Amounts billed and due from our customers are classified as receivables on the balance sheet and do not bear interest. Our deferred revenue primarily consists of amounts that have been invoiced but have not been recognized as revenue as of period end.Shipping and handling fees charged to our customers are recognized as revenue in the period shipped and the related costs for providing these services are recorded in cost of revenue. Shipping and handling fees recognized were not material during 2021, 2020 and 2019.

Warranties

Warranties—We generally provide a one-year warranty for most hardware products and a 90-day warranty for software. We also provide extended warranties under the terms of our support agreements. A provision for estimated future costs related to warranty activities in the first year after product sale is recorded as a component of cost of product revenues when the product revenue is recognized, based upon historical product failure rates and historical costs incurred in correcting product failures. Warranty costs related to extended warranties sold under support agreements are recognized as cost of service revenue as incurred. In the event we change our warranty reserve estimates, the resulting charge against future cost of revenue or reversal of previously recorded charges may materially affect our gross margins and operating results.

Contingent Liabilities

Contingent Liabilities—From time to time, we are involved in disputes, litigation, and other legal actions. There are many uncertainties associated with any disputes, litigation and other legal actions, and these actions or other third-party claims against us may cause us to incur costly litigation fees, costs and substantial settlement charges, and possibly subject us to damages and other penalties, which are inherently difficult to estimate and could adversely affect our results of operations. In addition, the resolution of any IP litigation may require us to make royalty payments, which could adversely affect our gross margins in future periods. We periodically review significant claims and litigation matters for the probability of an adverse outcome. Estimates can change as individual claims develop. The actual liability in any such matters may be materially different from our estimates, which could result in the need to adjust our liability and record additional expenses, which may be material.

Recently Adopted Accounting Standards and Recent Accounting Standards Not Yet Effective

Recently Adopted Accounting Standards

Income Taxes

In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2019-12—Income Taxes (“Topic 740”): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application and simplification of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 was effective for us beginning on January 1, 2021. The adoption of this guidance did not have any impact on our consolidated financial statements and accompanying disclosures.

Business Combinations

In October 2021, the FASB issued ASU 2021-08—Business Combinations (“Topic 805”): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in ASU 2021-08 require that an entity recognizes and measures contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers (“Topic 606”). At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. The amendments improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination.

We early adopted ASU 2021-08 on January 1, 2021 on a retrospective basis for all business combinations for which the acquisition date occurred subsequent to January 1, 2021. The adoption of ASU 2021-08 resulted in the increase of goodwill by $3.0 million attributable mainly to the acquisition of Alaxala in 2021, as a result of the revised measurement of the assumed deferred revenue balance. The adoption of ASU 2021-08 did not have a material impact to our consolidated statement of income or consolidated statement of cash flows. The adoption did not have a material impact on the other acquisitions in 2021.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
