Jun. 30, 2022
Accounting Policies [Abstract] |
Fiscal Year | Fiscal Year The Company uses a fiscal calendar year ending on June 30. All references herein to fiscal year ended “fiscal year ended 2022” or “2022”; “fiscal 2021” or “2021”; “fiscal 2020” or “2020” represent the fiscal years ending, respectively.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of Extreme Networks, Inc. and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. The Company predominantly uses the United States Dollar as its functional currency. The functional currency for certain of its foreign subsidiaries is the local currency. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated to United States Dollars at current month end exchange rates; and revenues and expenses are translated using the monthly average rate.
Accounting Estimates | Accounting Estimates The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ materially from these estimates.
Revenue Recognition | Revenue Recognition The Company accounts for revenue in accordance with Topic 606, Revenue from Contracts with Customers. The Company derives revenues primarily from sales of its networking equipment, with the remaining revenues generated from software delivered as a service (“SaaS”) and service fees relating to maintenance contracts, professional services, and training for the products. The Company recognizes revenues when control of promised goods or services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. See Note 3, Revenues, for further discussion. Revenue Recognition The Company derives the majority of its revenues from sales of its networking equipment, with the remaining revenues generated from sales of services and subscriptions, which primarily includes maintenance contracts and software subscriptions delivered as software as a service (“SaaS”) and additional revenues from professional services, and training for its products. The Company sells its products, maintenance contracts, and SaaS direct to customers and to partners in two distribution channels, or tiers. The first tier consists of a limited number of independent distributors that stock its products and sell primarily to resellers. The second tier of the distribution channel consists of a non-stocking distributors and value-added resellers that sell directly to end-users. Products and services may be sold separately or in bundled packages. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, the Company considers the promise to transfer products and services, each of which are distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. For all of the Company’s sales and distribution channels, revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment for product sales. Revenues from maintenance contracts and SaaS are recognized over time as the Company’s performance obligations are satisfied. This is typically the contractual service period, which generally ranges from one to five years. For product sales to value-added resellers of the Company, non-stocking distributors and end-user customers, the Company generally does not grant return privileges, except for defective products during the warranty period, nor does the Company grant pricing credits. Sales taxes collected from customers are excluded from revenues. Shipping costs are included in cost of product revenues. Sales incentives and other programs that the Company may make available to these customers are considered to be a form of variable consideration and the Company maintains estimated accruals and allowances using the historical actuals. There were no material changes in the current period to the estimated transaction price for performance obligations which were satisfied or partially satisfied during previous periods. Sales to stocking distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of the Company’s products held in their inventory. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Frequently, distributors need to sell at a price lower than the contractual distribution price in order to win business and submit rebate requests for the Company’s pre-approval prior to selling the product to a customer at the discounted price. At the time the distributor invoices its end customer or soon thereafter, the distributor submits a rebate claim to the Company to adjust the distributor’s cost from the contractual price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributor for the rebate claim. In determining the transaction price, the Company considers these rebate adjustments to be variable consideration. Such price adjustments are estimated based on an analysis of actual claims, at the distributor level over a period of time considered adequate to account for current pricing and business trends. Stock rotation adjustments are an additional form of variable consideration and are estimated based on historical return rates and estimates provided by the distributors. There were no material changes in the current period to the estimated variable consideration for performance obligations which were satisfied or partially satisfied during previous periods. Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Certain of the Company’s contracts have multiple performance obligations, as the promise to transfer individual goods or services is separately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on its relative standalone selling price. The stand-alone selling prices are determined based on the prices at which the Company separately sells these products. For items that are not sold separately, the Company estimates the stand-alone selling prices using the other observable inputs. The Company’s performance obligations are satisfied at a point in time or over time as the customer receives and consumes the benefits provided. Substantially all of the Company’s product sales revenues are recognized at a point in time. Substantially all of the Company’s service, subscription, and SaaS revenues are recognized over time. For revenue recognized over time, the Company primarily uses an input measure, days elapsed, to measure progress. At June 30, 2022, the Company had $401.6 million of remaining performance obligations, which are primarily comprised of deferred maintenance and SaaS revenues. The Company expects to recognize approximately 59% of this amount in fiscal 2023, an additional 21% percent in fiscal 2024 and 20% of the balance thereafter. Contract Balances. The timing of revenue recognition, billings and cash collections results in billed accounts receivable and deferred revenue in the consolidated balance sheets. Services provided under renewable support arrangements of the Company are billed in accordance with agreed-upon contractual terms, which are either billed fully at the inception of contract or at periodic intervals (e.g., quarterly or annually). The Company generally receives payments from its customers in advance of services being provided, resulting in deferred revenue. These liabilities are reported on the consolidated balance sheets on a contract-by-contract basis at the end of each reporting period. Revenue recognized for the years ended June 30, 2022 and 2021, that was included in the deferred revenue balance at the beginning of each period was $208.4 million and $188.4 million, respectively. Contract Costs. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. Management expects that commission fees paid to sales representatives as a result of obtaining service contracts and contract renewals, are recoverable and therefore the Company’s consolidated balance sheets included capitalized balances in the amount of $16.3 million and $13.1 million at June 30, 2022 and 2021, respectively. Capitalized commission fees are amortized on a straight-line basis over the average period of service contracts of approximately three years, and are included in “Sales and marketing” in the accompanying consolidated statements of operations. Amortization recognized during the years ended June 30, 2022, 2021 and 2020 was $7.5 million, $5.6 million and $5.2 million, respectively. Estimated Variable Consideration. There were no material changes in the current period to the estimated variable consideration for performance obligations which were satisfied or partially satisfied during previous periods. Disaggregation of Revenues: The Company operates in three geographic regions: Americas, which includes the United States, Canada, Mexico, Central America and South America; EMEA, which includes Europe, Russia, Middle East and Africa; and APAC which includes Asia Pacific, China, South Asia and Japan. The following tables set forth the Company’s revenues disaggregated by sales channel and geographic region based on the billing addresses of its customers (in thousands):

Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.
Allowance for Product Returns | Allowance for Product Returns The Company maintains estimates for product returns based on its historical returns, analysis of credit memos and its return policies. The allowance includes the estimates for product allowances from end customers as well as stock rotations and other returns from the Company’s stocking distributors. The allowance for product returns is shown as a reduction of accounts receivable as there is a contractual right of offset and returns are applied to accounts receivable balances outstanding as of the balance sheet date. There have not been material revisions to the estimated product returns for any periods presented.
Allowance for Credit Losses | Allowance for Credit Losses The Company maintains an allowance for credit losses which reflects its best estimate of potentially uncollectible trade receivables. The allowance consists of both specific and general reserves. The Company continually monitors and evaluates the collectability of its trade receivables based on a combination of factors. It records specific allowances for bad debts in general and administrative expense when it becomes aware of a specific customer’s inability to meet its financial obligation to the Company, such as in the case of bankruptcy filings or deterioration of financial position. Estimates are used in determining the allowances for all other customers based on factors such as current trends in the length of time the receivables are past due and historical collection experience. The Company mitigates some collection risk by requiring certain of its customers in the Asia-Pacific region to pay cash in advance or secure letters of credit when placing an order with the Company.
Inventories | Inventories The Company values its inventory at lower of cost or net realizable value. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company has established inventory allowances when conditions exist that suggest that inventory is obsolete or may be in excess of anticipated demand based upon assumptions about future demand. At the point of the loss recognition, a new lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Previously written down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods presented.
Long-Lived Assets | Long-Lived Assets Long-lived assets include (a) property and equipment, (b) operating lease right-of-use (“ROU”) assets, (c) goodwill and intangible assets, and (d) other assets. Property and equipment, ROU assets, and definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. (a) Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets. Estimated useful lives of one to four years are used for computer equipment and purchased software. Estimated useful lives of three to seven years are used for office equipment and furniture and fixtures. Depreciation and amortization of leasehold improvements is computed using the lesser of the useful life or lease terms. (b) Leases The Company leases facilities, equipment and vehicles under operating leases that expire on various dates through fiscal 2028. The Company determines if an arrangement is a lease at inception. We evaluate the classification of leases at commencement date and as necessary, at modification. In general, for lease arrangements exceeding a twelve-month term, these arrangements are recognized as ROU assets with associated operating lease liabilities on the consolidated balance sheets. ROU assets under the Company’s operating leases represent the Company’s right to use an underlying asset over the lease term. Operating lease liabilities represent the Company’s obligation to make payments arising from the lease. The ROU asset is reduced over a straight-line or other systematic basis representative of the pattern in which the Company expects to consume the ROU assets’ future economic benefits. The ROU asset is also adjusted for leasehold improvements paid by the lessor, lease incentives, and asset impairments, among other things. See Note 9, Leases, for further discussion. (c) Goodwill and Intangible Assets Goodwill and intangible assets are generated as a result of business combinations and are comprised of, among other things, developed technology, customer relationships, trade names, and licensing agreements. The remaining lives of intangibles are considered regularly along with assessments of impairment and lives are adjusted or impairment charges taken when required. Goodwill is calculated as the excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but rather is tested for impairment at least annually or more frequently if indicators of impairment are present. The Company has one reporting unit and performs its annual goodwill impairment analysis as of the first day of the fourth quarter of each year. In assessing impairment on goodwill, the Company bypasses the qualitative assessment and proceed directly to performing the quantitative evaluation of the fair value of the reporting unit, to compare against the carrying value of the reporting unit. A goodwill impairment charge is recognized for the amount by which the reporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Based on the results of the goodwill impairment analysis, the Company determined that no impairment charge needed to be recorded for any periods presented.
Business Combinations | Business Combinations The Company applies the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, useful lives, among other items. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. As a result, the Company may be required to value the acquired assets at fair value measures that do not reflect its intended use of those assets. Use of different estimates and judgments could yield different results. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. Although the Company believes the assumptions and estimates it has made are reasonable and appropriate, they are based in part on historical experience and information that may be obtained from the management of the acquired company and are inherently uncertain. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill for facts and considerations that were known at the acquisition date. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded within the Company’s consolidated statements of operations.
Deferred Revenue | Deferred Revenue Deferred revenue represents amounts for (i) deferred maintenance, support, and SaaS revenues, and (ii) other deferred revenue including professional services when the revenue recognition criteria have not been met.
Product Warranties and Guarantees | Product Warranties and Guarantees Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. The majority of the Company’s hardware products are shipped with either a one-year warranty or a limited lifetime warranty, and software products receive a 90-day warranty. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrues a liability in cost of product revenues for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors. In the normal course of business to facilitate sales of its products, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position.
Stock-Based Compensation | Stock-based Compensation The Company recognizes compensation expense related to stock-based awards, including stock options, restricted stock units (“RSUs”) and employee stock purchases related to its 2014 Employee Stock Purchase Plan (the “2014 ESPP”), based on the estimated fair value of the award on the grant date, over the requisite service period. The Company accounts for forfeitures as they occur. The Company calculates the fair value of stock options and share purchase options under the 2014 ESPP using the Black-Scholes-Merton option valuation model. The fair value of RSUs is based on the closing stock price of the Company’s common stock on the grant date. The Company grants certain employees performance-based stock options and RSUs. The performance metrics include company-wide financial performance and/or market conditions. For awards that include performance conditions, no compensation cost is recognized until the performance goals are probable of being met, at which time the cumulative compensation expense from the service inception date would be recognized. For awards that contain market conditions, compensation expense is measured using a Monte Carlo simulation model and recognized over the derived service period based on the expected market performance as of the grant date.
Advertising | Advertising Advertising costs are expensed as incurred. Advertising expenses were immaterial in fiscal years 2022, 2021 and 2020.
Income Taxes | Income Taxes The Company accounts for income taxes utilizing the liability method. Deferred income taxes are recorded to reflect consequences on future years of differences between financial reporting and the tax basis of assets and liabilities measured using the enacted statutory tax rates and tax laws applicable to the periods in which differences are expected to affect taxable earnings. A valuation allowance is recognized to the extent that it is more likely than not that the tax benefits will not be realized. The Company accounts for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. For additional discussion, see Note 16, Income Taxes.
Recently Issued and Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“the FASB”) issued ASU 2019-12, Income Taxes – Simplifying the Accounting for Income Taxes (Topic 740), which reduces the complexity of accounting for income taxes including the removal of certain exceptions to the general principles of Accounting Standards Codification (“ASC”) 740, Income Taxes, and simplification in several other areas such as accounting for franchise tax (or similar tax) that is partially based on income. This standard is effective for fiscal years beginning after December 15, 2020, including interim periods within the fiscal year. The standard was adopted on July 1, 2021 and did not have a material impact on the Company’s financial statements upon adoption. Recently Issued and Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities are recognized by the acquirer at fair value on the acquisition date. ASU 2021-08 is effective for annual periods beginning after December 15, 2022 and interim periods within those annual periods, with early adoption permitted, including adoption in an interim period. The Company elected to early adopt the standard in the quarter ended December 31, 2021 and retrospectively applied the standard to the acquisition that happened in the current fiscal year beginning July 1, 2021. The application of the guidance increased the deferred revenue balance acquired through the acquisition of Ipanema by $7.1 million as of the acquisition date.
Earnings Per Share | Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares of common stock used in the basic net income (loss) per share calculation plus the dilutive effect of shares subject to repurchase, options and unvested restricted stock.
