Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Mitek Systems, Inc. (“Mitek” or the “Company”) is a leading innovator of mobile image capture and digital identity verification solutions. Mitek is a software development company with expertise in computer vision, artificial intelligence, and machine learning. The Company is currently serving more than 7,500 financial services organizations and leading marketplace and financial technology (“fintech”) brands across the globe. The Company’s solutions are embedded in native mobile apps and browsers to facilitate better online user experiences, fraud detection and reduction, and compliant transactions. Mitek’s Mobile Deposit® solution is used today by millions of consumers in the United States (“U.S.”) and Canada for mobile check deposit. Mobile Deposit® enables individuals and businesses to remotely deposit checks using their camera-equipped smartphone or tablet. Mitek’s Mobile Deposit® solution is embedded within the financial institutions’ digital banking apps used by consumers and has now processed over four billion check deposits. Mitek began selling Mobile Deposit® in early 2008 and received its first patent for this product in August 2010. As of September 30, 2020, the Company has been granted 67 patents and it has an additional 20 patent applications pending. Mitek’s Mobile Verify® verifies a user’s identity online enabling organizations to build safer digital communities. Scanning an identity document helps enable an enterprise to verify the identity of the person with whom they are conducting business, to comply with growing governmental Anti-Money Laundering (“AML”) and Know Your Customer (“KYC”) regulatory requirements, and to improve the overall customer experience for digital onboarding. To be sure the person submitting the identity document is who they say they are, Mitek’s Mobile Verify Face Comparison provides an additional layer of online verification and compares the face on the submitted identity document with the live selfie photo of the user. The combination of identity document capture and data extraction process enables the organization to prefill the end user’s application, with far fewer key strokes, thus reducing keying errors, and improving both operational efficiency and the customer experience. Today, the financial services verticals (banks, credit unions, lenders, payments processors, card issuers, fintech companies, etc.) represent the greatest percentage of use of our solutions, but there is accelerated adoption by marketplaces, sharing economy, and hospitality sectors. Mitek uses artificial intelligence and machine learning to constantly improve the product performance of Mobile Verify® such as speed and accuracy of approvals of identification documents. The core of Mitek’s user experience is driven by Mitek MiSnap™, the leading image capture technology, which is incorporated across the Company’s product lines. It provides a simple, intuitive, and superior user-experience, making digital transactions faster, more accurate, and easier for the consumer. Mobile Fill® automates application prefill of any form with user data by simply snapping a picture of the driver’s license or other similar user identity document. CheckReader ™ enables financial institutions to automatically extract data from a check image received across any deposit channel—branch, ATM, remote deposit capture, and mobile. Through the automatic recognition of all fields on checks, whether handwritten or machine print, CheckReader ™ speeds the time to deposit for financial institutions and enables them to comply with check clearing regulations. The Company markets and sells its products and services worldwide through internal, direct sales teams located in the U.S., Europe, and Latin America as well as through channel partners. The Company’s partner sales strategy includes channel partners who are financial services technology providers and identity verification providers. These partners integrate the Company’s products into their solutions to meet the needs of their customers. Summary of Significant Accounting Policies Basis of Presentation The financial statements are prepared under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 105-10, Generally Accepted Accounting Principles , in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Foreign Currency The Company has foreign subsidiaries that operate and sell products and services in various countries and jurisdictions around the world. As a result, the Company is exposed to foreign currency exchange risks. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollars equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the consolidated balance sheet. The Company recorded net gains resulting from foreign exchange translation of $3.6 million for the fiscal year ended September 30, 2020, net losses resulting from foreign exchange translation of $3.5 million for the fiscal year ended September 30, 2019, and net losses resulting from foreign exchange translation of $0.7 million for the fiscal year ended September 30, 2018. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, deferred taxes, and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards, fair value of assets and liabilities acquired, impairment of goodwill, useful lives of intangible assets, standalone selling price related to revenue recognition, contingent consideration, and income taxes. Reclassifications Certain reclassifications have been made to prior year presentation to conform to the current year presentation. Prior to fiscal 2020, the Company had included its product management costs in selling and marketing expenses. Due to certain personnel and functional responsibility changes in this function, the Company has reclassified these costs to research and development expenses. To conform to the current period’s presentation, prior year’s financials have been reclassified accordingly. The Company has determined that this reclassification was not material to previously reported financial statements. Product management costs were $3.0 million, $2.9 million, and $2.4 million in fiscal years 2020, 2019, and 2018, respectively. Revenue Recognition The Company recognizes revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers , and its related amendments (collectively known as “ASC 606”). ASC 606 outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company generates revenue primarily from the delivery of licenses and related services to customers (for both on premise and transactional software as a service (“SaaS”) products), as well as the delivery of hardware and professional services. Revenue is measured based on consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time. See Note 2 of the consolidated financial statements for additional details. Contract Assets and Liabilities The Company recognizes revenue when control of the license is transferred to the customer. The Company records a contract asset when the revenue is recognized prior to the date payments become due. Contract assets that are expected to be paid within one year are recorded in current assets on the consolidated balance sheets. All other contract assets are recorded in other non-current assets in the consolidated balance sheet. Contract liabilities consist of deferred revenue. When the performance obligation is expected to be fulfilled within one year, the deferred revenue is recorded in current liabilities in the consolidated balance sheet. When the performance obligation is expected to be fulfilled beyond one year, the deferred revenue is recorded in non-current liabilities in the consolidated balance sheet. The Company reports net contract asset or liability positions on a customer-by-customer basis at the end of each reporting period. Contract Costs The Company incurs incremental costs to obtain a contract, consisting primarily of sales commissions incurred only if a contract is obtained. When the commission rate for a customer renewal is not commensurate with the commission rate for a new contract, the commission is capitalized if expected to be recovered. Such costs are capitalized and amortized using a portfolio approach consistent with the pattern of transfer of the good or service to which the asset relates. Contract costs are recorded in other current and non-current assets in the consolidated balance sheets. Net Income (Loss) Per Share The Company calculates net income (loss) per share in accordance with FASB ASC Topic 260, Earnings per Share . Basic net income (loss) per share is based on the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share also gives effect to all potentially dilutive securities outstanding during the period, such as restricted stock units (“RSUs”), stock options, and Employee Stock Purchase Plan ("ESPP") shares, if dilutive. In a period with a net loss position, potentially dilutive securities are not included in the computation of diluted net loss per share because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss per share is the same. For the fiscal years ended September 30, 2020, 2019 and 2018, the following potentially dilutive common shares were excluded from the net income (loss) per share calculation, as they would have been antidilutive (amounts in thousands) : 2020 2019 2018 Stock options 239 1,687 2,806 RSUs 1,519 2,352 2,580 ESPP common stock equivalents 14 74 71 Performance RSUs 32 — — Total potentially dilutive common shares outstanding 1,804 4,113 5,457 The calculation of basic and diluted net income (loss) per share for the fiscal years ended September 30, 2020, 2019, and 2018 is as follows (amounts in thousands, except per share data): 2020 2019 2018 Net income (loss) $ 7,814 $ (724) $ (11,807) Weighted-average shares outstanding—basic 41,410 39,341 35,811 Common stock equivalents 1,123 — — Weighted-average shares outstanding—diluted 42,533 39,341 35,811 Net income (loss) per share: Basic $ 0.19 $ (0.02) $ (0.33) Diluted $ 0.18 $ (0.02) $ (0.33) Cash and Cash Equivalents Cash and cash equivalents are defined as highly liquid financial instruments with original maturities of three months or less. The Company's cash and cash equivalents are composed of interest and non-interest-bearing deposits and money market funds. Investments Investments consist of corporate notes and bonds, commercial paper, U.S. Treasury securities, and asset-backed securities. The Company classifies investments as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive loss, a component of stockholders’ equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other-than-temporarily impaired. Impairments are considered to be other-than-temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before the recovery of its cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income (expense), net in the consolidated statements of operations and other comprehensive income (loss). No other-than-temporary impairment charges were recognized in the fiscal years ended September 30, 2020, 2019, and 2018. All investments whose maturity or sale is expected within one year are classified as “current” on the consolidated balance sheets. All other securities are classified as long-term on the consolidated balance sheets. Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected. The Company had $0.2 million and $0.1 million of write-offs to the allowance for doubtful accounts for the fiscal years ended September 30, 2020 and 2019, respectively. The Company had no write-offs to the allowance for doubtful accounts for the fiscal year ended September 30, 2018. The Company maintained an allowance for doubtful accounts of $0.2 million and $0.2 million as of September 30, 2020 and 2019, respectively. Property and Equipment Property and equipment are carried at cost. The following is a summary of property and equipment as of September 30, 2020 and 2019 (amounts shown in thousands): 2020 2019 Property and equipment—at cost: Leasehold improvements $ 3,639 $ 3,575 Equipment 3,545 3,041 Capitalized internal-use software development costs 1,363 1,088 Furniture and fixtures 618 526 9,165 8,230 Less: accumulated depreciation and amortization (5,555) (3,999) Total property and equipment, net $ 3,610 $ 4,231 Depreciation and amortization of property and equipment are provided using the straight-line method over estimated useful lives ranging from three Long-Lived Assets The Company evaluates the carrying value of long-lived assets, including license agreements and other intangible assets, when events and circumstances indicate that these assets may be impaired or in order to determine whether any revision to the related amortization periods should be made. This evaluation is based on management’s projections of the undiscounted future cash flows associated with each product or asset. If management’s evaluation indicates that the carrying values of these intangible assets were 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. The Company did not record any impairment of long-lived assets for the fiscal years ended September 30, 2020, 2019, and 2018. Capitalized Software Development Costs Costs incurred for the development of software that will be sold, leased, or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the fiscal years ended September 30, 2020 and 2019, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material or were not realizable. The Company had no amortization expense from capitalized software costs during the years ended September 30, 2020, 2019, or 2018. Costs related to software acquired, developed, or modified solely to meet our internal requirements, with no substantive plans to market such software at the time of development, are capitalized. Costs incurred during the preliminary planning and evaluation stage of the project and during the post-implementation operational stage are expensed as incurred. Costs incurred during the application development stage of the project are capitalized. The Company defines the design, configuration, and coding process as the application development stage. The Company capitalized $0.3 million, $0.2 million, and $0.9 million of costs related to computer software developed for internal use during the years ended September 30, 2020, 2019 and 2018, respectively. The Company recognized $0.4 million, $0.3 million and $0.1 million of amortization expense from internal use software during the years ended September 30, 2020, 2019 and 2018, respectively. Goodwill and Purchased Intangible Assets The Company’s goodwill and intangible assets resulted from prior acquisitions. Goodwill and intangible assets with indefinite useful lives are not amortized, but are tested for impairment at least annually or as circumstances indicate that their value may no longer be recoverable. In accordance with ASC Topic 350, Intangibles—Goodwill and Other (“ASC Topic 350”), the Company reviews its goodwill and indefinite-lived intangible assets for impairment at least annually in its fiscal fourth quarter and more frequently if events or changes in circumstances occur that indicate a potential reduction in the fair value of its reporting unit and/or its indefinite-lived intangible asset below their respective carrying values. Examples of such events or circumstances include: a significant adverse change in legal factors or in the business climate, a significant decline in the Company’s stock price, a significant decline in the Company’s projected revenue or cash flows, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, or the presence of other indicators that would indicate a reduction in the fair value of a reporting unit. No such events or circumstances have occurred since the last impairment assessment was performed. The Company’s goodwill is considered to be impaired if management determines that the carrying value of the reporting unit to which the goodwill has been assigned exceeds management’s estimate of its fair value. Based on the guidance provided by ASC 350 and ASC Topic 280, Segment Reporting , management has determined that the Company operates in one segment and consists of one reporting unit. Because the Company has only one reporting unit, and because the Company is publicly traded, the Company determines the fair value of the reporting unit based on its market capitalization as it believes this represents the best evidence of fair value. In the fourth quarter of fiscal 2020, management completed its annual goodwill impairment test and concluded that the Company’s goodwill was not impaired. The Company’s conclusion that goodwill was not impaired was based on a comparison of its net assets to its market capitalization. Because the Company determines the fair value of its reporting unit based on its market capitalization, the Company’s future reviews of goodwill for impairment may be impacted by changes in the price of the Company’s common stock, par value $0.001 per share ("Common Stock"). For example, a significant decline in the price of the Common Stock may cause the fair value of its goodwill to fall below its carrying value. Therefore, the Company cannot assure that when it completes its future reviews of goodwill for impairment, a material impairment charge will not be recorded. Intangible assets are amortized over their useful lives. Each period, the Company evaluates the estimated remaining useful life of its intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. The carrying amounts of these assets are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Recoverability of these assets is measured by comparing the carrying amount of each asset to the future undiscounted cash flows the asset is expected to generate. The carrying amount of such assets is reduced to fair value if the undiscounted cash flows used in the test for recoverability are less than the carrying amount of such assets. No impairment charge related to the impairment of intangible assets was recorded during the fiscal years ended September 30, 2020, 2019, and 2018. Other Borrowings The Company has certain loan agreements with Spanish government agencies which were assumed when the Company acquired ICAR Vision Systems, S.L. (“ICAR”). These agreements have repayment periods of five Guarantees In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC Topic 460, Guarantees (“ASC 460”), except for standard indemnification and warranty provisions that are contained within many of the Company’s customer license and service agreements and certain supplier agreements, and give rise only to the disclosure requirements prescribed by ASC 460. Indemnification and warranty provisions contained within the Company’s customer license and service agreements and certain supplier agreements are generally consistent with those prevalent in the Company’s industry. The Company has not historically incurred significant obligations under customer indemnification or warranty provisions and does not expect to incur significant obligations in the future. Accordingly, the Company does not maintain accruals for potential customer indemnification or warranty-related obligations. Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. Management evaluates the available evidence about future taxable income and other possible sources of realization of deferred tax assets. The valuation allowance reduces deferred tax assets to an amount that represents management’s best estimate of the amount of such deferred tax assets that more likely than not will be realized. See Note 8 of the consolidated financial statements for additional details. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters in income tax expense. See Note 8 of the consolidated financial statements for additional details. Stock-Based Compensation The Company issues RSUs, stock options, performance options, and Senior Executive Long-Term Incentive Restricted Stock Units (“Senior Executive Performance RSUs”) as awards to its employees. Additionally, eligible employees may participate in the Company’s ESPP. Employee stock awards are measured at fair value on the date of grant and expense is recognized using the straight-line single-option method in accordance with FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). Forfeitures are recorded as they occur. The Company assigns fair value to RSUs based on the closing stock price of its Common Stock on the date of grant. The Company estimates the fair value of stock options and ESPP shares using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected life of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods. The Company estimates the fair value of performance options, Senior Executive Performance RSUs, and similar awards using the Monte-Carlo simulation. The Monte-Carlo simulation requires subjective assumptions, including the Company’s valuation date stock price, the annual risk-free interest rate, expected volatility, the probability of reaching the stock performance targets, and a 20-trading-day average stock price. Advertising Expense Advertising costs are expensed as incurred and totaled $1.6 million, $0.8 million and $0.5 million during the fiscal years ended September 30, 2020, 2019, and 2018, respectively. Research and Development Research and development costs are expensed in the period incurred. Segment Reporting FASB ASC Topic 280, Segment Reporting , requires the use of a management approach in identifying segments of an enterprise. During the fiscal year ended September 30, 2020, management determined that the Company has only one operating segment: the development, sale, and service of proprietary software solutions related to mobile imaging. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income (loss), unrealized gains and losses on available-for-sale securities, and foreign currency translation adjustments. Included on the consolidated balance sheet is an accumulated other comprehensive loss of $0.3 million and $4.1 million at September 30, 2020 and 2019, respectively. Recently Adopted Accounting Pronouncements In February 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Incom e, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Jobs Act”). The Company elected not to reclassify the stranded tax effects to retained earnings as they were not material the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 and its related amendments (collectively, known as “ASC 842”) which require lessees to record most leases on the balance sheet but recognize expenses in the income statement in a manner similar to previous guidance. The way in which entities classify leases determines how to recognize lease-related revenue and expenses. The Company adopted ASC 842 as of October 1, 2019 using the optional transition method and will not adjust the comparative period financial statements for the effects of the new standard or make the new, expanded required disclosures for periods prior to the adoption date. Accordingly, the results for the twelve months ended September 30, 2019 continue to be reported under the accounting guidance, ASC Topic 840, Leases (“ASC 840”), in effect for that period. The Company elected to use the package of practical expedients to not reassess: (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases, and (iii) initial direct costs for any existing leases. The Company also elected the practical expedient not to separate the non-lease components of a contract from the lease component to which they relate. In addition, the Company made an accounting policy election that will keep leases with an initial term of twelve months or less off the consolidated balance sheet. The adoption of ASC 842 had a material impact on the consolidated balance sheet as of October 1, 2019, and resulted in the recognition of $8.2 million of lease liabilities and $6.8 million of right-of-use (“ROU”) assets for those leases classified as operating leases. The adoption of ASC 842 did not have a material impact on the Company’s consolidated statements of operations and other comprehensive income (loss) or consolidated statements of cash flows. See Note 9 of the consolidated financial statements for additional details. Change in Significant Accounting Policy Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in its consolidated financial statements. The details of the significant changes and quantitative impact of the changes are disclosed below. Leases The Company determines if an arrangement is a lease at inception in accordance with ASC 842. The lease term begins on the commencement date, which is the date the Company takes possession of the property, and may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease term is used to determine lease classification as an operating or finance lease and is used to calculate straight-line expense for operating leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments arising from the lease. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes, which are comprised of real estate leases and auto leases. ROU assets and lease liabilities are recognized at commencement date based upon the present value of lease payments over the lease term. ROU assets also include prepaid lease payments and exclude lease incentives received. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. Since the Company’s leases do not typically provide an implicit rate, the Company uses its incremental borrowing rate based upon the information available at commencement date of each lease. The determination of the incremental borrowing rate requires judgment. The Company determines the incremental borrowing rate using the Company’s current secured borrowing rate. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of twelve months or less are not recorded on the consolidated balance sheet; instead, lease payments are recognized as lease expenses on a straight-line basis over the lease term. See Note 9 of the consolidated financial statements for additional details. Operating lease assets and liabilities are recognized for leases with lease terms greater than 12 months based on the present value of the future lease payments over the lease term at the commencement date. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheet. Operating leases are included in Right-of-use-assets, Lease liabilities, current portion and Lease liabilities, non-current portion on our consolidated balance sheet. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such option. We account for substantially all lease

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	2. REVENUE RECOGNITION Nature of Goods and Services The following is a description of principal activities from which the Company generates its revenue. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below. Software and Hardware Software and hardware revenue is generated from on premise software license sales, as well as sales of hardware scanner boxes and on premise appliance products. For software license agreements that are distinct, the Company recognizes software license revenue upon delivery and after evidence of a contract exists. Hardware revenue is recognized in the period that the hardware is shipped. Services and Other Services and other revenue is generated from the sale of transactional SaaS products and services, maintenance associated with the sale of software and hardware, and consulting and professional services. The Company recognizes services and other revenue over the period in which such services are performed. The Company’s model typically includes an up-front fee and a periodic commitment from the customer that commences upon completion of the implementation through the remainder of the customer life. The up-front fee is the initial setup fee, or the implementation fee. The periodic commitment includes, but is not limited to, a fixed periodic fee and/or a transactional fee based on system usage that exceeds committed minimums. If the up-front fee is not distinct, revenue is deferred until the date the customer commences use of the Company’s services, at which point the up-front fee is recognized ratably over the life of the customer arrangement. The Company does not view the signing of the contract or the provision of initial setup services as discrete earnings events that are distinct. Significant Judgments in Application of the Guidance The Company uses the following methods, inputs, and assumptions in determining amounts of revenue to recognize: Identification of Performance Obligations For contracts that contain multiple performance obligations, which include combinations of software licenses, maintenance, and services, the Company accounts for individual goods or services as a separate performance obligation if they are distinct. The good or service is distinct if the good or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determination of Transaction Price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The Company includes any fixed charges within its contracts as part of the total transaction price. To the extent that variable consideration is not constrained, the Company includes an estimate of the variable amount, as appropriate, within the total transaction price and updates its assumptions over the duration of the contract. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less. Assessment of Estimates of Variable Consideration Many of the Company’s contracts with customers contain some component of variable consideration; however, the constraint will generally not result in a reduction in the estimated transaction price for most forms of variable consideration. The Company may constrain the estimated transaction price in the event of a high degree of uncertainty as to the final consideration amount owed because of an extended length of time over which the fees may be adjusted. Allocation of Transaction Price The transaction price, including any discounts, is allocated between separate goods and services in a contract that contains multiple performance obligations based on their relative standalone selling prices. The standalone selling prices are determined based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using available information such as market conditions and internally approved pricing guidelines. In instances where there are observable selling prices for professional services and support and maintenance, the Company may apply the residual approach to estimate the standalone selling price of software licenses. In certain situations, primarily transactional SaaS revenue described above, the Company allocates variable consideration to a series of distinct goods or services within a contract. The Company allocates variable payments to one or more, but not all, of the distinct goods or services or to a series of distinct goods or services in a contract when (i) the variable payment relates specifically to the Company’s efforts to transfer the distinct good or service and (ii) the variable payment is for an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to its customer. Disaggregation of Revenue The following table presents the Company's revenue disaggregated by major product category ( amounts in thousands ): Twelve Months Ended September 30, 2020 2019 2018 Major product category Deposits software and hardware $ 49,765 $ 41,860 $ 33,071 Deposits services and other 17,965 15,170 8,437 Deposits revenue 67,730 57,030 41,508 Identity verification software and hardware 4,387 4,985 7,627 Identity verification services and other 29,193 22,575 14,424 Identity verification revenue 33,580 27,560 22,051 Total revenue $ 101,310 $ 84,590 $ 63,559 Software and hardware revenue is generated from on premise software license sales, as well as sales of hardware scanner boxes and on premise appliance products. Services and other revenue is generated from the sale of transactional SaaS products and services, maintenance associated with the sale of software and hardware, and consulting and professional services. Contract Balances The following table provides information about contract assets and contract liabilities from contracts with customers ( amounts in thousands ): September 30, 2020 September 30, 2019 Contract assets, current $ 5,187 $ 2,350 Contract assets, non-current 4,468 581 Contract liabilities (deferred revenue), current 7,973 5,612 Contract liabilities (deferred revenue), non-current 1,597 736 Contract assets, reported within current assets and other long-term assets in the consolidated balance sheets, primarily result from revenue being recognized when a license is delivered and payments are made over time. Contract liabilities primarily relate to advance consideration received from customers, deferred revenue, for which transfer of control occurs, and therefore revenue is recognized, as services are provided. Contract balances are reported in a net contract asset or liability position on a customer-by-customer basis at the end of each reporting period. The Company recognized $3.9 million and $4.4 million of revenue during the twelve months ended September 30, 2020 and 2019, respectively, which was included in the contract liability balance at the beginning of each such period. Contract Costs Contract costs included in other current and non-current assets on the consolidated balance sheets totaled $1.5 million and $1.5 million at September 30, 2020 and September 30, 2019, respectively. Contract costs are amortized based on the transfer of goods or services to which the asset relates. The amortization period also considers expected customer lives and whether the asset relates to goods or services transferred under a specific anticipated contract. These costs are included in selling and marketing expenses in the consolidated statement of operations and other comprehensive income (loss) and totaled $0.8 million and $0.6 million during the years ended September 30, 2020 and 2019, respectively. There were no impairment losses recognized during the years ended September 30, 2020 and 2019 related to capitalized contract costs.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	3. BUSINESS COMBINATIONS A2iA Group II, S.A.S. On May 23, 2018, the Company acquired all of the issued and outstanding shares of A2iA Group II, S.A.S. (“A2iA”), a simplified joint stock company formed under the laws of France, pursuant to a share purchase agreement, by and among the Company, each of the holders of outstanding shares of A2iA and Andera Partners, S.C.A., as representative of the sellers (the “A2iA Acquisition”). A2iA is a software development organization focused on delivering specialized and highly intelligent data extraction tools that enable customers to optimize their data capture, document processing, and workflow automation capabilities. Upon completion of the A2iA Acquisition, A2iA became a direct wholly owned subsidiary of the Company. The A2iA Acquisition extends Mitek’s global leadership position in both mobile check deposit and digital identity verification and combines the two market leaders in document recognition and processing. As consideration for the A2iA Acquisition, the Company (i) made a cash payment of $26.8 million, net of cash acquired; (ii) issued 2,514,588 shares, or $21.9 million, of the Company’s Common Stock; and (iii) incurred transaction related liabilities of $0.2 million. The Company incurred $2.2 million of expense in fiscal year 2018 in connection with the A2iA Acquisition primarily related to legal fees, outside service costs, and travel expense, which are included in acquisition-related costs and expenses in the consolidated statements of operations and other comprehensive income (loss). On May 23, 2018, the Company deposited $0.7 million of the cash payment and 508,479 shares, or $4.4 million, of Common Stock into an escrow fund to serve as collateral and partial security for certain indemnification rights of the Company. The escrow fund was maintained for 24 months following the completion of the A2iA Acquisition and no claims were made against the escrow fund. The Company used cash on hand for the cash paid on May 23, 2018. ICAR Vision Systems, S.L. On October 16, 2017, Mitek Holding B.V., a company incorporated under the laws of The Netherlands and a wholly owned subsidiary of the Company (“Mitek Holding B.V.”), acquired all of the issued and outstanding shares of ICAR, a company incorporated under the laws of Spain (the “ICAR Acquisition”), and each of its subsidiaries, pursuant to a Share Purchase Agreement (the “Purchase Agreement”), by and among, the Company, Mitek Holding B.V., and each of the shareholders of ICAR (the “Sellers”). ICAR is a technology provider of identity fraud proofing and document management solutions for web, desktop, and mobile platforms. Upon completion of the ICAR Acquisition, ICAR became a direct wholly owned subsidiary of Mitek Holding B.V. and an indirect wholly owned subsidiary of the Company. ICAR is a leading provider of consumer identity verification solutions in Spain and Latin America. The ICAR Acquisition strengthens the Company’s position as a global digital identity verification powerhouse in the Consumer Identity and Access Management solutions market. As consideration for the ICAR Acquisition, the Company agreed to an aggregate purchase price of up to $13.9 million, net of cash acquired. On October 16, 2017, the Company: (i) made a cash payment to Sellers of $3.0 million, net of cash acquired and subject to adjustments for transaction expenses, escrow amounts, indebtedness, and working capital adjustments; and (ii) issued to Sellers 584,291 shares, or $5.6 million, of Common Stock. In addition to the foregoing, the Sellers may be entitled to additional cash consideration upon achievement of certain milestones as follows: (a) subject to achievement of the revenue target for the fourth quarter of calendar 2017, the Company will pay to Sellers up to $1.5 million (the “Q4 Consideration”), which amount shall be deposited (as additional funds) into the escrow fund described below; and (b) subject to achievement of certain revenue and net income targets for ICAR for the twelve-month period ending on September 30, 2018, and the twelve-month period ending on September 30, 2019, the Company will pay to Sellers up to $3.8 million in additional cash consideration (the “Earnout Consideration”); provided that if the revenue target set forth in clause (a) is not met, then the Q4 Consideration will instead be added to the Earnout Consideration payable upon (and subject to) achievement of the revenue and net income targets for the twelve-month period ending on September 30, 2018. The Company estimated the fair value of the total Q4 Consideration and Earnout Consideration to be $2.9 million on October 16, 2017, which was determined using a discounted cash flow methodology based on financial forecasts determined by management that included assumptions about revenue growth and discount rates. Each quarter the Company revises the estimated fair value of the Earnout Consideration and revises as necessary. The Company incurred $0.5 million of expense in connection with the ICAR Acquisition primarily related to legal fees, outside service costs, and travel expense, which are included in acquisition-related costs and expenses in the consolidated statements of operations and other comprehensive income (loss). On October 16, 2017, the Company deposited $1.5 million of cash into an escrow fund to serve as collateral and partial security for working capital adjustments and certain indemnification rights. In April 2018, the Q4 Consideration of $1.5 million was deposited into the escrow fund. As a result of the achievement of earnout targets during fiscal 2018, the Company paid $1.8 million in January 2019. The Company extended the period over which the remaining $1.8 million of Earnout Consideration is earned. $1.1 million of the Earnout Consideration was paid during second quarter of fiscal 2020 based on the achievement of revenue and income targets earned during fiscal 2019. The remaining portion of the Earnout Consideration of $0.8 million will be paid out during the second quarter of fiscal 2021 due to the achievement of certain revenue, income, development and corporate targets during fiscal 2020. During the first quarter of fiscal 2020, the Company released all escrow funds, excluding $1.0 million which is being held for any potential settlement relating to the claims which may arise from the litigation which was brought on by Global Equity & Corporate Consulting, S.L. against ICAR as more fully described in Note 9. The Company used cash on hand for cash paid on October 16, 2017, and under the terms of the Purchase Agreement, the Company has agreed to guarantee the obligations of Mitek Holding B.V. thereunder. Acquisitions are accounted for using the purchase method of accounting in accordance with ASC Topic 805, Business Combinations . Accordingly, the results of operations of A2iA and ICAR have been included in the accompanying consolidated financial statements since the date of each acquisition. The purchase price for both the A2iA Acquisition and the ICAR Acquisition have been allocated to the tangible and intangible assets acquired and liabilities assumed based upon the respective estimates of fair value as of the date of each acquisition, and are based on assumptions that the Company’s management believes are reasonable given the information currently available. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed during the year ended September 30, 2018 ( amounts shown in thousands ): A2iA ICAR Total Current assets $ 3,929 $ 2,036 $ 5,965 Property, plant, and equipment 307 83 390 Intangible assets 28,610 6,407 35,017 Goodwill 24,991 6,936 31,927 Other non-current assets 1,177 87 1,264 Current liabilities (2,688) (1,652) (4,340) Deferred income tax liabilities (7,503) (1,602) (9,105) Other non-current liabilities (7) (828) (835) Net assets acquired $ 48,816 $ 11,467 $ 60,283 The goodwill recognized is due to expected synergies and other factors and is not expected to be deductible for income tax purposes. The Company estimated the fair value of identifiable acquisition-related intangible assets with definite lives primarily based on discounted cash flow projections that will arise from these assets. The Company exercised significant judgment with regard to assumptions used in the determination of fair value such as with respect to discount rates and the determination of the estimated useful lives of the intangible assets. The following table summarizes the estimated fair values and estimated useful lives of intangible assets with definite lives acquired during the year ended September 30, 2018 ( amounts shown in thousands, except for years ): Amortization Period Amount assigned A2iA Completed technologies 7.0 years $ 13,015 Customer relationships 5.0 years 15,360 Trade names 5.0 years 235 Total intangible assets acquired from A2iA $ 28,610 ICAR Completed technologies 5.0 years $ 4,956 Customer relationships 2.0 years 1,298 Trade names 3.0 years 153 Total intangible assets acquired from ICAR $ 6,407 The following unaudited pro forma financial information is presented as if the acquisitions had taken place at the beginning of the periods presented and should not be taken as representative of the Company’s future consolidated results of operations. The following unaudited pro forma information includes adjustments for the amortization expense related to the identified intangible assets. The following table summarizes the Company’s unaudited pro forma financial information is presented as if the acquisitions occurred on October 1, 2017 ( amounts shown in thousands ): For the years ended September 30, 2020 2019 2018 Pro forma revenue $ 101,310 $ 86,206 $ 78,130 Pro forma net income (loss) $ 7,814 $ 889 $ (12,268) For the year ended September 30, 2018, revenue of $9.1 million and a net loss of $5.3 million from the A2iA and ICAR businesses since the respective acquisition dates are included in the Company's consolidated statements of operations.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	4. RESTRUCTURING Subsequent to the A2iA Acquisition, the Company evaluated A2iA’s operations and determined that the market for certain products was small and lacking growth opportunity and that its products were not core to Mitek’s strategy, nor were they profitable for the Company. In order to streamline the organization and focus resources going forward, the Company undertook a strategic restructuring of A2iA’s Paris operations in June 2019, which included, among other things, ceasing the sale of certain A2iA products and offerings and a reduction in workforce. Restructuring costs consist of employee severance obligations and other related costs. As the restructuring plan has been completed, the Company reversed the remaining accrued costs in the fourth quarter of fiscal 2020. The following table summarizes changes in the restructuring accrual during the year ended September 30, 2020 (amounts shown in thousands) : Balance at September 30, 2019 $ 1,526 Accrual reversed (114) Payments (1,412) Foreign currency effect on the restructuring accrual — Balance at September 30, 2020 $ —

Investments, Debt and Equity Securities [Abstract]
INVESTMENTS	5. INVESTMENTS The Company determines the appropriate designation of investments at the time of purchase and reevaluates such designation as of each balance sheet date. All of the Company’s investments are designated as available-for-sale debt securities. As of September 30, 2020 and 2019, the Company’s short-term investments have maturity dates of less than one year from the balance sheet date. The Company’s long-term investments have maturity dates of greater than one year from the balance sheet date. Available-for-sale marketable securities are carried at fair value as determined by quoted market prices for identical or similar assets, with unrealized gains and losses, net of taxes, and reported as a separate component of stockholders’ equity. Management reviews the fair value of the portfolio at least monthly and evaluates individual securities with fair value below amortized cost at the balance sheet date. For debt securities, in order to determine whether impairment is other-than-temporary, management must conclude whether the Company intends to sell the impaired security and whether it is more likely than not that the Company will be required to sell the security before recovering its amortized cost basis. If management intends to sell an impaired debt security or it is more likely than not that the Company will be required to sell the security prior to recovering its amortized cost basis, an other-than-temporary impairment is deemed to have occurred. The amount of an other-than-temporary impairment on debt securities related to a credit loss, or securities that management intends to sell before recovery, is recognized in earnings. The amount of an other-than-temporary impairment on debt securities related to other factors is recorded consistent with changes in the fair value of all other available-for-sale securities as a component of stockholders’ equity in other comprehensive income (loss). No other-than-temporary impairment charges were recognized in the fiscal years ended September 30, 2020, 2019, and 2018. There were no realized gains or losses from the sale of available-for-sale securities during the years ended September 30, 2020 and 2019. The Company recorded a net realized loss from the sale of available-for-sale securities of $49,000 during the year ended September 30, 2018. The cost of securities sold is based on the specific identification method. Amortization of premiums, accretion of discounts, interest, dividend income, and realized gains and losses are included in other income, net in the consolidated statements of operations and other comprehensive income (loss). The following tables summarize investments by type of security as of September 30, 2020 and 2019, respectively (amounts shown in thousands): September 30, 2020: Cost Gross Unrealized Gains Gross Unrealized Losses Fair Market Value Available-for-sale securities: U.S. Treasury, short-term $ 10,245 $ 38 $ — $ 10,283 Asset-backed securities, short-term 4,723 36 — 4,759 Corporate debt securities, short-term 24,956 37 — 24,993 Corporate debt securities, long-term 1,966 — (3) 1,963 Total $ 41,890 $ 111 $ (3) $ 41,998 September 30, 2019: Cost Gross Gross Fair Market Available-for-sale securities: U.S. Treasury, short-term $ 4,240 $ 2 $ — $ 4,242 Corporate debt securities, short-term 12,258 2 — 12,260 U.S. Treasury, long-term 1,102 — (1) 1,101 Corporate debt securities, long-term 451 — — 451 Total $ 18,051 $ 4 $ (1) $ 18,054 Fair Value Measurements and Disclosures FASB ASC Topic 820, Fair Value Measurements (“ASC 820”) defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 describes a fair value hierarchy based on the following three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which consists of the following: • Level 1—Quoted prices in active markets for identical assets or liabilities; • Level 2—Inputs other than Level 1 inputs that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following tables represent the fair value hierarchy of the Company’s investments and acquisition-related contingent consideration as of September 30, 2020 and 2019, respectively (amounts shown in thousands): September 30, 2020: Balance Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Short-term investments: U.S. Treasury $ 10,283 $ 10,283 $ — $ — Asset-backed securities 4,759 — 4,759 — Corporate debt securities Financial 7,695 — 7,695 — Industrial 1,924 — 1,924 — Commercial paper Financial 13,479 — 13,479 — Industrial 1,895 — 1,895 — Total short-term investments at fair value 40,035 10,283 29,752 — Long-term investments: U.S. Treasury — — — — Asset-backed securities — — — — Corporate debt securities Financial 977 — 977 — Industrial 986 — 986 — Total assets at fair value $ 41,998 $ 10,283 $ 31,715 $ — Liabilities: Acquisition-related contingent consideration 753 — — 753 Total liabilities at fair value $ 753 $ — $ — $ 753 September 30, 2019: Balance Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Short-term investments: U.S. Treasury $ 4,242 $ 4,242 $ — $ — Corporate debt securities Financial 2,503 — 2,503 — Industrial 1,371 — 1,371 — Commercial paper Financial 5,560 — 5,560 — Industrial 2,826 — 2,826 — Total short-term investments at fair value 16,502 4,242 12,260 — Long-term investments: U.S. Treasury 1,101 1,101 — — Corporate debt securities Financial 451 — 451 — Industrial — — — — Total assets at fair value $ 18,054 $ 5,343 $ 12,711 $ — Liabilities: Acquisition-related contingent consideration 1,601 — — 1,601 Total liabilities at fair value $ 1,601 $ — $ — $ 1,601 As of September 30, 2020, total acquisition-related contingent consideration related to the ICAR Acquisition of $0.8 million is recorded in acquisition-related contingent consideration and other non-current liabilities, in the consolidated balance sheets.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	6. GOODWILL AND INTANGIBLE ASSETS Goodwill The Company has goodwill balances of $35.7 million and $32.6 million at September 30, 2020 and 2019, respectively, representing the excess of costs over fair value of net assets of businesses acquired. Goodwill acquired in a business combination and determined to have an indefinite useful life is not amortized, but instead is tested for impairment at least annually in accordance with ASC Topic 350. The following table summarizes changes in the balance of goodwill during the year ended September 30, 2020 ( amounts shown in thousands ): Balance at September 30, 2019 $ 32,636 Other adjustments (1) 806 Foreign currency effect on goodwill 2,227 Balance at September 30, 2020 $ 35,669 (1) During the three months ended December 31, 2019, the Company determined that it had incorrectly classified $0.8 million of contract assets in its fair value estimate associated with the A2iA Acquisition. This asset was incorrectly recorded as other non-current assets with an offset to goodwill on the Company’s consolidated balance sheet during the three months ended June 30, 2018 and subsequent financial statements. The Company has determined that the adjustment was not material to any previously reported financial statements. Therefore, the consolidated balance sheet as of September 30, 2020 has been adjusted Intangible Assets Intangible assets include the value assigned to purchased completed technology, customer relationships, and trade names. The estimated useful lives for all of these intangible assets, range from two (amounts shown in thousands, except for years): September 30, 2020: Weighted Average Amortization Period Cost Accumulated Amortization Net Completed technologies 6.4 years $ 20,341 $ 9,416 $ 10,925 Customer relationships 4.8 years 17,628 9,390 8,238 Trade names 4.5 years 618 492 126 Total intangible assets $ 38,587 $ 19,298 $ 19,289 September 30, 2019: Weighted Average Amortization Period Cost Accumulated Amortization Net Completed technologies 6.4 years $ 20,341 $ 7,104 $ 13,237 Customer relationships 4.8 years 17,628 6,701 10,927 Trade names 4.5 years 618 377 241 Total intangible assets $ 38,587 $ 14,182 $ 24,405 Amortization expense related to acquired intangible assets was $6.4 million, $7.0 million, and $4.0 million for fiscal years ended September 30, 2020, 2019, and 2018, respectively and is recorded in acquisition-related costs and expenses in the consolidated statements of operations. The estimated future amortization expense related to intangible assets for each of the five succeeding fiscal years is expected to be as follows (amounts shown in thousands): Estimated Future Amortization Expense 2021 $ 6,368 2022 5,956 2023 3,909 2024 1,857 2025 1,199 Thereafter — Total $ 19,289

STOCKHOLDERS' EQUITY	7. STOCKHOLDERS’ EQUITY Stock-Based Compensation Expense The following table summarizes stock-based compensation expense related to RSUs, stock options, and ESPP shares for the fiscal years ended September 30, 2020, 2019, and 2018, which were allocated as follows (amounts shown in thousands): 2020 2019 2018 Cost of revenue $ 267 $ 207 $ 78 Selling and marketing 2,528 2,554 2,383 Research and development 2,802 2,426 2,074 General and administrative 3,954 4,450 4,415 Stock-based compensation expense included in expenses $ 9,551 $ 9,637 $ 8,950 The fair value calculations for stock-based compensation awards to employees for the fiscal years ended September 30, 2020, 2019, and 2018 were based on the following assumptions: 2020 2019 2018 Risk-free interest rate 1.35% – 1.35% 1.85% – 3.08% 2.04% Expected life (years) 5.78 5.43 5.15 Expected volatility 48% 57% 60% Expected dividends — — — The expected life of options granted is derived using assumed exercise rates based on historical exercise patterns and vesting terms, and represents the period of time that options granted are expected to be outstanding. Expected stock price volatility is based upon implied volatility and other factors, including historical volatility. After assessing all available information on either historical volatility, or implied volatility, or both, the Company concluded that a combination of both historical and implied volatility provides the best estimate of expected volatility. As of September 30, 2020, the Company had $17.9 million of unrecognized compensation expense related to outstanding RSUs, stock options, and ESPP shares expected to be recognized over a weighted-average period of approximately 2.3 years. 2012 Incentive Plan In January 2012, the Company’s board of directors (the “Board”) adopted the Mitek Systems, Inc. 2012 Incentive Plan (the “2012 Plan”), upon the recommendation of the compensation committee of the Board.

The Performance RSUs are subject to vesting based on a performance-based condition and a service-based condition. The Performance RSU will vest over four years in a percentage of the target number of shares between 0 and 100%, depending on the extent the performance condition is achieved. The following table summarizes Performance RSU activity under the Company’s equity plans in the fiscal years ended September 30, 2020, 2019, and 2018: Number of Shares Weighted- Average Fair Value Per Share Outstanding at September 30, 2017 2,100,000 $ 7.71 Granted — $ — Exercised — $ — Canceled (57,183) $ 9.45 Outstanding at September 30, 2018 2,042,817 $ 7.66 Granted — $ — Exercised — $ — Canceled (320,266) $ 7.11 Outstanding at September 30, 2019 1,722,551 $ 7.76 Granted 353,556 $ 6.06 Exercised — $ — Canceled (1,722,551) $ 7.76 Outstanding at September 30, 2020 353,556 $ 6.06 There were 353,556 Performance RSUs outstanding as of September 30, 2020. The Company recognized $0.7 million, $1.0 million, and $1.5 million in stock-based compensation expense related to outstanding Performance RSUs in the fiscal years ended September 30, 2020, 2019, and 2018, respectively. As of September 30, 2020, the Company had $1.4 million of unrecognized compensation expense related to outstanding Performance RSUs expected to be recognized over a weighted-average period of approximately 1.7 years. During the year ended September 30, 2020, the Company cancelled 1,722,551 of previously issued Performance RSUs as the performance criteria were not met during the performance period. Performance Options On November 6, 2018, as an inducement grant pursuant to Nasdaq Listing Rule 5635(c)(4), the Company’s Chief Executive Officer was granted performance options (the “Performance Options”) to purchase up to 800,000 shares of Common Stock at an exercise price of $9.50 per share, the closing market price for a share of the Common Stock on the date of the grant. As long as he remains employed by the Company, such Performance Options shall vest upon the closing market price of the Common Stock achieving certain predetermined levels and his serving as the Chief Executive Officer of the Company for at least three years. In the event of a change of control of the Company, all of the unvested Performance Options will vest if the per share price payable to the stockholders of the Company in connection with the change of control is an amount reaching those certain predetermined levels required for the Performance Options to otherwise vest. The Company recognized $0.8 million and $0.7 million in stock-based compensation expense related to outstanding Performance Options in the years ended September 30, 2020 and 2019, respectively. As of September 30, 2020, the Company had $0.9 million of unrecognized compensation expense related to outstanding Performance Options expected to be recognized over a weighted-average period of approximately 1.1 years. Closing Shares On June 17, 2015, the Company completed the acquisition of ID Checker NL B.V., a company incorporated under the laws of The Netherlands (“IDC NL”), and ID Checker, Inc., a California corporation and wholly owned subsidiary of IDC NL (“IDC Inc.” and together with IDC NL, “ID Checker”). In connection with the closing of this acquisition, the Company issued to the Sellers 712,790 shares of Common Stock (the "Closing Shares"). Vesting of these shares is subject to the continued employment of the founders of ID Checker and occurs over a period of 27 months from the date of issuance. The cost of the Closing Shares was determined using the fair value of the Common Stock on the award date, and the stock-based compensation is recognized ratably over the 27 month vesting period. Stock-based compensation expense related to the Closing Shares is recorded within acquisition-related costs and expenses on the consolidated statements of operations and other comprehensive income (loss). The Company recognized no stock-based compensation expense related to the Closing Shares in the years ended September 30, 2020, 2019, and 2018. Earnout Shares In connection with the acquisition of ID Checker, the Company issued 137,306 shares of Common Stock (the "Earnout Shares") to the Sellers for achievement by ID Checker of certain revenue targets for the nine-month period ended September 30, 2015. Additionally, 81,182 Earnout Shares were earned by the Sellers for achievement by ID Checker of certain revenue targets for the twelve-month period ended September 30, 2016. The Company estimated the fair value of the Earnout Shares using the Monte-Carlo simulation (using the Company’s valuation date stock price, the annual risk-free interest rate, expected volatility, the probability of reaching the performance targets, and a 10 trading day average stock price). In November 2017, a contingency triggered the immediate vesting of all Earnout Shares, resulting in an acceleration of all stock-based compensation related to the Earnout Shares. Stock-based compensation expense related to the Earnout Shares is recorded within acquisition-related costs and expenses on the consolidated statements of operations and other comprehensive income (loss). The Company did not recognize any stock-based compensation expense related to the Earnout Shares for each of the years ended September 30, 2020 and 2019. The Company recognized $0.4 million in stock-based compensation expense related to the Earnout Shares for the year ended September 30, 2018. Share Repurchase Program On December 13, 2019, the Board authorized and approved a share repurchase program for up to $10.0 million of the currently outstanding shares of the Company’s Common Stock. The share repurchase program will expire December 16, 2020. The purchases under the share repurchase program may be made from time to time in the open market, through block trades, 10b5-1 trading plans, privately negotiated transactions or otherwise, in each case, in accordance with applicable laws, rules, and regulations. The timing and actual number of the shares repurchased will depend on a variety of factors including price, market conditions, and corporate and regulatory requirements. The Company intends to fund the share repurchases from cash on hand. The share repurchase program does not commit the Company to repurchase shares of its Common Stock and it may be amended, suspended, or discontinued at any time. The Company made purchases of $1.0 million, or approximately 137,000 shares, during the fiscal year ended September 30, 2020 at an average price of $7.33 per share. Total purchases made under the share repurchase program were $1.0 million as of September 30, 2020 and the repurchased shares were retired. Rights Agreement On October 23, 2018, the Company entered into the Section 382 Rights Agreement (the “Rights Agreement”) and issued a dividend of one preferred share purchase right (a “Right”) for each share of Common Stock payable on November 2, 2018 to the stockholders of record of such shares on that date. Each Right entitles the registered holder, under certain circumstances, to purchase from the Company one one-thousandth of a share of Series B Junior Preferred Stock, par value $0.001 per share (the “Preferred Shares”), of the Company, at a price of $35.00 per one one-thousandth of a Preferred Share represented by a Right, subject to adjustment. The description and terms of the Rights are set forth in the Rights Agreement. The Rights are not exercisable until the Distribution Date (as defined in the Rights Agreement). Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. At any time prior to the time any person becomes an Acquiring Person (as defined in the Rights Agreement), the Board may redeem the Rights in whole, but not in part, at a price of $0.0001 per Right (the “Redemption Price”). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. The Rights will expire on the earlier of (i) the close of business on October 22, 2021, (ii) the time at which the Rights are redeemed, and (iii) the time at which the Rights are exchanged. On February 28, 2019, the Company entered into an Amendment No. 1 to the Rights Agreement for the purpose of (i) modifying the definitions of “Beneficial Owner,” “Beneficially Own,” and “Beneficial Ownership” under the Rights Agreement to more closely align such definitions to the actual and constructive ownership rules under Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”) or such similar provisions of the Tax Cuts and Jobs Act of 2017 and the rules and regulations promulgated thereunder, and (ii) adding an exemption request process for persons to seek an exemption from becoming an “Acquiring Person” under the Rights Agreement in the event such person wishes to acquire 4.9% or more of the Common Stock then outstanding.

INCOME TAXES	8. INCOME TAXES Provision for Income Taxes Income (loss) before income taxes for the years ended September 30, 2020, 2019, and 2018 is comprised of the following ( amounts shown in thousands ): 2020 2019 2018 Domestic $ 11,071 $ 8,992 $ (1,584) Foreign (1,662) (12,980) (7,157) Total $ 9,409 $ (3,988) $ (8,741) For the years ended September 30, 2020, 2019, and 2018 the income tax benefit (provision) was as follows (amounts shown in thousands): 2020 2019 2018 Federal—current $ — $ (117) $ (87) Federal—deferred (2,182) 639 (4,537) State—current (46) (438) (26) State—deferred 67 515 773 Foreign—current (436) 594 (270) Foreign—deferred 1,002 2,071 1,081 Total $ (1,595) $ 3,264 $ (3,066) Deferred Income Tax Assets and Liabilities Significant components of the Company’s net deferred tax assets and liabilities as of September 30, 2020 and 2019 are as follows (amounts shown in thousands): 2020 2019 Deferred tax assets: Stock-based compensation $ 2,503 $ 2,646 Net operating loss carryforwards 5,931 9,419 Research credit carryforwards 6,264 5,570 Lease liability 1,091 — Intangibles 300 58 Other, net — 90 Total deferred assets 16,089 17,783 Deferred tax liabilities: Right of use asset (726) — Foreign deferred liabilities (5,756) (5,811) Other, net (62) — Net deferred tax asset 9,545 11,972 Valuation allowance for net deferred tax assets (710) (931) Net deferred tax asset $ 8,835 $ 11,041 The net change in the total valuation allowance for the fiscal years ended September 30, 2020 and 2019 was a decrease of $0.2 million and an increase of $0.5 million, respectively. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. The Company considers projected future taxable income and planning strategies in making this assessment. Based on the level of historical operating results and the projections for future taxable income, the Company has determined that it is more likely than not that the deferred tax assets may be realized for all deferred tax assets with the exception of the net foreign deferred tax assets at Mitek Systems B.V, which the Company has recorded a full valuation allowance. As of September 30, 2020, the Company has available net operating loss carryforwards of $16.0 million for federal income tax purposes. The Company did not generate any net operating losses in the fiscal year ended September 30, 2020. Of the remaining net operating losses, $2.2 million can be carried forward indefinitely, and $13.8 million, which were generated prior to the fiscal year 2020, will start to expire in 2032 unless previously utilized. The net operating losses for state purposes are $28.1 million, which will begin to expire in 2028. As of September 30, 2020, the Company has available federal research and development credit carryforwards, net of reserves, of $3.2 million. The federal research and development credits will start to expire in 2022. As of September 30, 2020, the Company has available California research and development credit carryforwards, net of reserves, of $2.8 million, which do not expire. Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “IRC”) limit the utilization of tax attribute carryforwards that arise prior to certain cumulative changes in a corporation’s ownership. The Company has completed an IRC Section 382/383 analysis through March 31, 2017 and any identified ownership changes had no impact to the utilization of tax attribute carryforwards. Any future ownership changes may have an impact on the utilization of the tax attribute carryforwards. Income Tax Provision Reconciliation The difference between the income tax benefit (provision) and income taxes computed using the U.S. federal income tax rate was as follows for the years ended September 30, 2020, 2019, and 2018 (amounts shown in thousands): 2020 2019 2018 Amount computed using statutory rate $ (1,977) $ 841 $ 2,122 Net change in valuation allowance for net deferred tax assets 221 (459) (367) Other — — (191) Foreign rate differential 86 664 22 Non-deductible items (178) (151) (276) State income tax (205) (370) 50 Impact of tax reform on deferred taxes — — (4,901) Research and development credits 897 1,694 475 Foreign income tax 10 (494) — Stock compensation, net (449) 1,539 — Income tax benefit (provision) $ (1,595) $ 3,264 $ (3,066) Uncertain Tax Positions In accordance with authoritative guidance, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The following table reconciles the beginning and ending amount of unrecognized tax benefits for the fiscal years ended September 30, 2020, 2019, and 2018 (amounts shown in thousands): 2020 2019 2018 Gross unrecognized tax benefits at the beginning of the year $ 1,607 $ 1,321 $ 1,181 Additions from tax positions taken in the current year 203 213 140 Additions from tax positions taken in prior years — 73 — Reductions from tax positions taken in prior years — — — Tax settlements — — — Gross unrecognized tax benefits at end of the year $ 1,810 $ 1,607 $ 1,321 Of the total unrecognized tax benefits at September 30, 2020, $1.8 million will impact the Company’s effective tax rate. The Company does not anticipate that there will be a substantial change in unrecognized tax benefits within the next twelve months. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of September 30, 2020, no accrued interest or penalties related to uncertain tax positions are recorded in the consolidated financial statements. The Company is subject to income taxation in the U.S. at the federal and state levels. All tax years are subject to examination by U.S., California, and other state tax authorities due to the carryforward of unutilized net operating losses and tax credits. The Company is also subject to foreign income taxes in the countries in which it operates. The examination of the Company’s U.S. federal tax return for the year ended September 30, 2017 was completed during the fourth quarter of fiscal 2020. To our knowledge, the Company is not currently under examination by any other taxing authorities. Tax Cuts and Jobs Act On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (the “Tax Cuts and Jobs Act"). The Tax Cuts and Jobs Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. federal corporate tax rate from a maximum of 35% to a flat 21%, effective January 1, 2018. In conjunction with the tax law changes, the Securities and Exchange Commission staff issued Staff Accounting Bulletin 118 ("SAB 118") to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act. In accordance with SAB 118, the Company completed the accounting for the remeasurement of deferred tax assets and liabilities in the year ended September 30, 2020, which included the period of enactment. Additionally, for the fiscal year ended September 30, 2020, the entire fiscal year’s activity was under the 21% tax rate. CARES Act

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	9. COMMITMENTS AND CONTINGENCIES Leases The Company’s principal executive offices, as well as its research and development facility, are located in approximately 29,000 square feet of office space in San Diego, California and the term of the lease continues through June 30, 2024. The average annual base rent under this lease is approximately $1.2 million per year. In connection with this lease, the Company received tenant improvement allowances totaling approximately $1.0 million. These lease incentives are being amortized as a reduction of rent expense over the term of the lease. As of September 30, 2020, the unamortized balance of the lease incentives was $0.5 million, of which $0.1 million has been included in other current liabilities and $0.4 million has been included in other non-current liabilities. The Company’s other offices are located in Paris, France; Amsterdam, The Netherlands; New York, New York; Barcelona, Spain; and London, United Kingdom. The term of the Paris, France lease continues through July 31, 2021, with an annual base rent of approximately €0.4 million (or $0.4 million). The term of the Amsterdam, The Netherlands lease continues through December 31, 2022, with an annual base rent of approximately €0.3 million (or $0.3 million). The term of the New York, New York lease continues through November 30, 2024, with an annual base rent of approximately $0.2 million. The term of the Barcelona, Spain lease continues through May 31, 2023, with an annual base rent of approximately €0.1 million (or $0.1 million). The term of the London, United Kingdom lease continues through February 28, 2021, with an annual base rent of approximately £112,200 (or approximately $143,000). Other than the lease for office space in San Diego, California, the Company does not believe that the leases for the offices are material to the Company. The Company believes its existing properties are in good condition and are sufficient and suitable for the conduct of its business. The Company’s leases have remaining terms of 1 to 8 years. Certain leases contain renewal options for varying periods, which are at the Company’s sole discretion. For leases where the Company is reasonably certain to exercise a renewal option, such option periods have been included in the determination of the Company’s ROU assets and lease liabilities. As of September 30, 2020, the weighted-average remaining lease term for the Company’s operating leases was 4.4 years and the weighted-average discount rate was 4.7%. Lease liabilities expected to be paid within one year are recorded in current liabilities in the consolidated balance sheets. All other lease liabilities are recorded in non-current liabilities in the consolidated balance sheets. As of September 30, 2020, the Company had operating ROU assets of $5.4 million. Total operating lease liabilities of $7.1 million were comprised of current lease liabilities of $1.8 million and non-current lease liabilities of $5.3 million. The Company recognized $2.2 million of operating lease costs in the twelve months ended September 30, 2020. Operating lease costs are included within cost of revenue, selling and marketing, research and development, and general and administrative expenses, dependent upon the nature and use of the ROU asset, in the Company’s consolidated statement of operations and other comprehensive income (loss). Rent expense for the Company’s operating leases for its facilities for the years ended September 30, 2020, 2019, and 2018 totaled $2.2 million, $2.1 million and $1.7 million, respectively. The Company paid $1.7 million in operating cash flows for operating leases in the twelve months ended September 30, 2020. Maturities of our operating lease liabilities as of September 30, 2020 were as follows (amounts shown in thousands) : Operating leases 2021 $ 2,100 2022 1,721 2023 1,721 2024 1,388 2025 301 Thereafter 672 Total lease payments 7,903 Less: amount representing interest (757) Present value of future lease payments $ 7,146 As determined under ASC 840, the future minimum lease payments related to lease agreements with a remaining noncancelable term in excess of one year, as of September 30, 2019 were as follows: Operating leases 2020 $ 1,641 2021 2,157 2022 1,777 2023 1,550 2024 1,151 2025 36 Thereafter — Total minimum lease payments $ 8,312 Claim Against ICAR On June 11, 2018, a claim was filed before the Juzgado de Primera Instancia number 5 of Barcelona, Spain, the first instance court in the Spanish civil procedure system, against ICAR. The claim, also directed to Mr. Xavier Codó Grasa, former controlling shareholder of ICAR and its current General Manager, was brought by the Spanish company Global Equity & Corporate Consulting, S.L. for the alleged breach by ICAR of a services agreement entered into in the context of the sale of the shares in ICAR to Mitek Holding B.V. ICAR responded to the claim on September 7, 2018 and the court process is ongoing but has been delayed as a consequence of the COVID-19 pandemic. The amount claimed is €0.8 million (or $0.9 million), plus the interest accrued during the court proceedings. Pursuant and subject to the terms of the sale and purchase agreement concerning the acquisition of the shares in ICAR, Mitek Holding B.V. is to be indemnified in respect of any damages suffered by ICAR and/or Mitek Holding B.V. in respect of this claim. Third-Party Claims Against Our Customers The Company is subject to indemnification demands related to various offers to license patents and allegations of patent infringement against several end-customers. Some of the offers and allegations have resulted in ongoing litigation. The Company is not a party to any such litigation. License offers to and infringement allegations against the Company’s end-customers were made by Lighthouse Consulting Group, LLC; Lupercal, LLC; Pebble Tide, LLC; Dominion Harbor Group, LLC; and IP Edge, LLC, which appear to be non-practicing entities (“NPEs”)—often called “patent trolls”—and not the Company’s competitors. These NPEs may seek to extract settlements from our end-customers, resulting in new or renewed indemnification demands to the Company. At this time, the Company does not believe it is obligated to indemnify any customers or end-customers resulting from license offers or patent infringement allegations by the companies listed above. However, the Company could incur substantial costs if it is determined that it is required to indemnify any customers or end-customers in connection with these offers or allegations. Given the potential for impact to other customers and the industry, the Company is actively monitoring the offers, allegations and any resulting litigation. On July 7, 2018, United Services Automobile Association (“USAA”) filed a lawsuit against Wells Fargo Bank, N.A. (“Wells Fargo”) in the Eastern District of Texas alleging that Wells Fargo’s remote deposit capture systems (which in part utilize technology provided by the Company to Wells Fargo through a partner) infringe four USAA owned patents related to mobile deposits (the “First Wells Lawsuit”). On August 17, 2018, USAA filed a second lawsuit (the “Second Wells Lawsuit” and together with the First Wells Lawsuit, the “Wells Lawsuits”) against Wells Fargo in the Eastern District of Texas asserting that an additional five patents owned by USAA were infringed by Wells Fargo’s remote deposit capture system. Subsequently, on November 6, 2019, a jury in the First Wells Lawsuit found that Wells Fargo willfully infringed at least one of the Subject Patents (as defined below) and awarded USAA $200 million in damages. In the Second Wells Lawsuit, USAA dropped two of the patents from the litigation, and the judge in the case found that one of the remaining three patents was invalid. On January 10, 2020, a jury in the Second Wells Lawsuit found that Wells Fargo willfully infringed at least one of the patents at issue in that case and awarded USAA $102 million in damages. No Mitek product was accused of infringing either of the two patents in question in the Second Wells Lawsuit as the litigation involved broad banking processes and not Mitek’s specific mobile deposit features. The jury verdicts are subject to post-trial motions and appeal by Wells Fargo. The Wells Lawsuits are ongoing and no final judgments or awards have been made to date. Wells Fargo filed petitions for Inter Partes Review (“IPR”) with the Patent Trial and Appeal Board (“PTAB”) challenging the validity of the four patents in the First Wells Lawsuit. Three of those four petitions were instituted, while one (relating to the ‘090 Patent) was denied institution. On November 24, 2020, the PTAB issued final written decisions determining that Wells Fargo had not demonstrated by a preponderance of the evidence that any claims of the ‘571 Patent or the ‘779 Patent were unpatentable. Wells Fargo can request rehearing of these decisions and/or appeal the decisions to the U.S. Court of Appeals for the Federal Circuit. The PTAB is still considering the final Wells Fargo IPR petition (for the ‘517 patent) and has not yet issued a final written decision. On September 30, 2020, USAA filed suit against PNC Bank (the “PNC Lawsuit”) in the Eastern District of Texas alleging infringement of U.S. Patent Nos. 10,482,432 and 10,621,559. These two patents are continuations of an asserted patent in the Second Wells Lawsuit and relate to similar subject matter. On October 19, 2020, PNC Bank’s integration partner, NCR Corporation, sent an indemnification demand to the Company requesting indemnification from all claims related to the PNC Lawsuit. At this time, the Company does not believe it is obligated to indemnify NCR Corporation or end-users of NCR Corporation resulting from the patent infringement allegations by USAA. While neither the Wells Lawsuits nor the PNC Lawsuit name the Company as a defendant, given (among other factors) the Company’s prior history of litigation with USAA and the continued use of Mitek’s products by its customers, on November 1, 2019, the Company filed a Complaint in the U.S. District Court for the Northern District of California seeking declaratory judgment that its products do not infringe USAA’s U.S. Patent Nos. 8,699,779 (the “’779 Patent”); 9,336,517 (the “’517 Patent”); 9,818,090 (the “’090 Patent”); and 8,977,571 (the “’571 Patent”) (collectively, the “Subject Patents”). On January 15, 2020, USAA filed motions requesting the dismissal of the declaratory judgement of the Subject Patents and transfer of the case to the Eastern District of Texas, both of which the Company opposed. On April 21, 2020, the court in the Northern District of California transferred Mitek’s declaratory judgement action to the Eastern District of Texas and did not rule on USAA’s motion to dismiss. On July 15, 2020, the court in the Eastern District of Texas held a hearing on USAA’s motion to dismiss, but has not yet issued a ruling. The Company continues to believe that its products do not infringe the Subject Patents and will vigorously defend the right of its end-users to use its technology. In April, May, and June 2020, the Company filed petitions for IPR with the PTAB of the U.S. Patent & Trademark Office challenging the validity of the Subject Patents. On November 6 and 17, 2020, the PTAB decided to exercise its discretion and deny institution of three of the four petitions due to the alleged relationship between the Company and Wells Fargo, who previously filed petitions for IPR on the Subject Patents. The PTAB did not address the merits of the Company’s petitions or the prior art cited in those petitions. The PTAB has not yet decided whether it will institute the final IPR petition. The Company continues to believe that the prior art cited in the petitions renders all the claims of the Subject Patents invalid. On December 6, 2020, the Company filed requests for rehearing and Precedential Opinion Panel (“POP”) review of the denied IPR petition for the ‘090 Patent. The Company is evaluating all of it options with respect to the remaining petitions, including requests for rehearing and POP review. The Company incurred legal fees of $3.2 million in the fiscal year ended September 30, 2020 related to third-party claims against our customers. Such fees are included in general and administrative expenses in the consolidated statement of operations and other comprehensive income (loss). Claim Against UrbanFT, Inc. On July 31, 2019, the Company filed a lawsuit against one of its customers, UrbanFT, Inc. (“UrbanFT”) in the United States District Court for the Southern District of California (case No. 19-CV-1432-CAB-DEB). UrbanFT is delinquent in payment and attempted to justify its non-payment by asserting that the Company is or may be infringing on purported Urban FT patents. The Company filed such lawsuit to collect the delinquent payments and to obtain a declaratory judgment of non-infringement of five purported UrbanFT patents. UrbanFT filed an answer to the complaint but did not file any cross-claims for infringement. UrbanFT later amended its answer to assert infringement of two of the five patents-at-issue in the Company’s lawsuit against UrbanFT. The Company thereafter filed counterclaims seeking a declaration that the two patents now asserted by UrbanFT are invalid in addition to being not infringed. During the course of the litigation, the Company learned that a judgment had been entered against UrbanFT’s affiliates and its predecessor owner in which an Oregon court ordered that the patents in issue revert to a prior owner because UrbanFT’s affiliates did not pay the purchase price owed to the prior owner. Pleadings were closed on April 28, 2020. On September 8, 2020, the Company filed a motion for summary judgment on its breach of contract claim, and on September 15, 2020, the district court issued an order to show cause regarding jurisdiction over patent issues given the Oregon judgment. The Company’s summary judgment and the patent jurisdiction issues are fully briefed to the court. All trial and other dates have been vacated pending these rulings. The Company intends to vigorously pursue its claims and defend against any claims of infringement. Other Legal Matters In addition to the foregoing, the Company is subject to various claims and legal proceedings arising in the ordinary course of its business. The Company accrues for such liabilities when it is both (i) probable that a loss has occurred and (ii) the amount of the loss can be reasonably estimated in accordance with ASC 450, Contingencies . While any legal proceeding has an element of uncertainty, the Company believes that the disposition of such matters, in the aggregate, will not have a material effect on the Company’s financial condition or results of operations. Employee 401(k) Plan The Company has a 401(k) plan that allows participating employees to contribute a percentage of their salary, subject to Internal Revenue Service annual limits. In 2015, the Company implemented a company match to the plan. The Company's contributions are made in an amount equal to 50% of the first 6% of an employee's designated deferral of their eligible compensation. The Company's total cost related to the 401(k) plan was $420,000, $231,000, and $123,000 for the fiscal years ended September 30, 2020, 2019, and 2018, respectively. Revolving Credit Facility

REVENUE CONCENTRATION	10. REVENUE CONCENTRATION Revenue Concentration For the year ended September 30, 2020, the Company derived revenue of $15.8 million from one customer, with such customer accounting for 16% of the Company’s total revenue. For the year ended September 30, 2019, the Company derived revenue of $22.8 million from two customers, with such customers accounting for 17% and 10% of the Company's total revenue. For the year ended September 30, 2018, the Company derived revenue of $20.0 million from two customers, with such customers accounting for 22% and 10% of the Company’s total revenue. The corresponding accounts receivable balances of customers from which revenues were in excess of 10% of total revenue were $4.5 million, $5.4 million, and $5.7 million at September 30, 2020, 2019, and 2018, respectively. The Company’s revenue is derived primarily from the sale by the Company to channel partners, including systems integrators and resellers, and end-users of licenses to sell products covered by the Company’s patented technologies. These contractual arrangements do not obligate the Company’s channel partners to order, purchase or distribute any fixed or minimum quantities of the Company’s products. In most cases, the channel partners purchase the license from the Company after they receive an order from an end-user. The channel partners receive orders from various individual end-users; therefore, the sale of a license to a channel partner may represent sales to multiple end-users. End-users can purchase the Company’s products through more than one channel partner. Revenues can fluctuate based on the timing of license renewals by channel partners. When a channel partner purchases or renews a license, the Company receives a license fee in consideration for the grant of a license to sell the Company’s products and there are no future payment obligations related to such agreement; therefore, the license fee the Company receives with respect to a particular license renewal in one period does not have a correlation with revenue in future periods. During the last several quarters, sales of licenses to one or more channel partners have comprised a significant part of the Company’s revenue. This is attributable to the timing of renewals or purchases of licenses and does not represent a dependence on any single channel partner. The Company believes that it is not dependent upon any single channel partner, even those from which revenues were in excess of 10% of the Company’s total revenue in a specific reporting period, and that the loss or termination of the Company’s relationship with any such channel partner would not have a material adverse effect on the Company’s future operations because either the Company or another channel partner could sell the Company’s products to the end-user that had purchased from the channel partner the Company lost. International sales accounted for approximately 24%, 31%, and 27% of the Company’s total revenue for the years ended September 30, 2020, 2019, and 2018, respectively. From a geographic perspective, approximately 66% and 68% of the Company’s total long-term assets as of September 30, 2020 and 2019, respectively, are associated with the Company’s international subsidiaries. From a geographic perspective, approximately 15% and 12% of the Company’s total long-term assets excluding goodwill and other intangible assets as of September 30, 2020 and 2019, respectively, are associated with the Company’s international subsidiaries.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Mitek Systems, Inc. (“Mitek” or the “Company”) is a leading innovator of mobile image capture and digital identity verification solutions. Mitek is a software development company with expertise in computer vision, artificial intelligence, and machine learning. The Company is currently serving more than 7,500 financial services organizations and leading marketplace and financial technology (“fintech”) brands across the globe. The Company’s solutions are embedded in native mobile apps and browsers to facilitate better online user experiences, fraud detection and reduction, and compliant transactions. Mitek’s Mobile Deposit® solution is used today by millions of consumers in the United States (“U.S.”) and Canada for mobile check deposit. Mobile Deposit® enables individuals and businesses to remotely deposit checks using their camera-equipped smartphone or tablet. Mitek’s Mobile Deposit® solution is embedded within the financial institutions’ digital banking apps used by consumers and has now processed over four billion check deposits. Mitek began selling Mobile Deposit® in early 2008 and received its first patent for this product in August 2010. As of September 30, 2020, the Company has been granted 67 patents and it has an additional 20 patent applications pending. Mitek’s Mobile Verify® verifies a user’s identity online enabling organizations to build safer digital communities. Scanning an identity document helps enable an enterprise to verify the identity of the person with whom they are conducting business, to comply with growing governmental Anti-Money Laundering (“AML”) and Know Your Customer (“KYC”) regulatory requirements, and to improve the overall customer experience for digital onboarding. To be sure the person submitting the identity document is who they say they are, Mitek’s Mobile Verify Face Comparison provides an additional layer of online verification and compares the face on the submitted identity document with the live selfie photo of the user. The combination of identity document capture and data extraction process enables the organization to prefill the end user’s application, with far fewer key strokes, thus reducing keying errors, and improving both operational efficiency and the customer experience. Today, the financial services verticals (banks, credit unions, lenders, payments processors, card issuers, fintech companies, etc.) represent the greatest percentage of use of our solutions, but there is accelerated adoption by marketplaces, sharing economy, and hospitality sectors. Mitek uses artificial intelligence and machine learning to constantly improve the product performance of Mobile Verify® such as speed and accuracy of approvals of identification documents. The core of Mitek’s user experience is driven by Mitek MiSnap™, the leading image capture technology, which is incorporated across the Company’s product lines. It provides a simple, intuitive, and superior user-experience, making digital transactions faster, more accurate, and easier for the consumer. Mobile Fill® automates application prefill of any form with user data by simply snapping a picture of the driver’s license or other similar user identity document. CheckReader ™ enables financial institutions to automatically extract data from a check image received across any deposit channel—branch, ATM, remote deposit capture, and mobile. Through the automatic recognition of all fields on checks, whether handwritten or machine print, CheckReader ™ speeds the time to deposit for financial institutions and enables them to comply with check clearing regulations. The Company markets and sells its products and services worldwide through internal, direct sales teams located in the U.S., Europe, and Latin America as well as through channel partners. The Company’s partner sales strategy includes channel partners who are financial services technology providers and identity verification providers. These partners integrate the Company’s products into their solutions to meet the needs of their customers.
Basis of Presentation	Basis of Presentation The financial statements are prepared under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 105-10, Generally Accepted Accounting Principles , in accordance with accounting principles generally accepted in the U.S. (“GAAP”).
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Foreign Currency	Foreign CurrencyThe Company has foreign subsidiaries that operate and sell products and services in various countries and jurisdictions around the world. As a result, the Company is exposed to foreign currency exchange risks. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollars equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the consolidated balance sheet.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, deferred taxes, and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards, fair value of assets and liabilities acquired, impairment of goodwill, useful lives of intangible assets, standalone selling price related to revenue recognition, contingent consideration, and income taxes.
Reclassifications	ReclassificationsCertain reclassifications have been made to prior year presentation to conform to the current year presentation. Prior to fiscal 2020, the Company had included its product management costs in selling and marketing expenses. Due to certain personnel and functional responsibility changes in this function, the Company has reclassified these costs to research and development expenses. To conform to the current period’s presentation, prior year’s financials have been reclassified accordingly.
Revenue Recognition, Contract Assets and Liabilities and Contract Costs	Revenue Recognition The Company recognizes revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers , and its related amendments (collectively known as “ASC 606”). ASC 606 outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company generates revenue primarily from the delivery of licenses and related services to customers (for both on premise and transactional software as a service (“SaaS”) products), as well as the delivery of hardware and professional services. Revenue is measured based on consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time. See Note 2 of the consolidated financial statements for additional details. Contract Assets and Liabilities The Company recognizes revenue when control of the license is transferred to the customer. The Company records a contract asset when the revenue is recognized prior to the date payments become due. Contract assets that are expected to be paid within one year are recorded in current assets on the consolidated balance sheets. All other contract assets are recorded in other non-current assets in the consolidated balance sheet. Contract liabilities consist of deferred revenue. When the performance obligation is expected to be fulfilled within one year, the deferred revenue is recorded in current liabilities in the consolidated balance sheet. When the performance obligation is expected to be fulfilled beyond one year, the deferred revenue is recorded in non-current liabilities in the consolidated balance sheet. The Company reports net contract asset or liability positions on a customer-by-customer basis at the end of each reporting period. Contract Costs The Company incurs incremental costs to obtain a contract, consisting primarily of sales commissions incurred only if a contract is obtained. When the commission rate for a customer renewal is not commensurate with the commission rate for a new contract, the commission is capitalized if expected to be recovered. Such costs are capitalized and amortized using a portfolio approach consistent with the pattern of transfer of the good or service to which the asset relates. Contract costs are recorded in other current and non-current assets in the consolidated balance sheets.
Net Income (Loss) Per Share	Net Income (Loss) Per Share The Company calculates net income (loss) per share in accordance with FASB ASC Topic 260, Earnings per Share . Basic net income (loss) per share is based on the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share also gives effect to all potentially dilutive securities outstanding during the period, such as restricted stock units (“RSUs”), stock options, and Employee Stock Purchase Plan ("ESPP") shares, if dilutive. In a period with a net loss position, potentially dilutive securities are not included in the computation of diluted net loss per share because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss per share is the same.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are defined as highly liquid financial instruments with original maturities of three months or less. The Company's cash and cash equivalents are composed of interest and non-interest-bearing deposits and money market funds.
Investments	Investments Investments consist of corporate notes and bonds, commercial paper, U.S. Treasury securities, and asset-backed securities. The Company classifies investments as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive loss, a component of stockholders’ equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other-than-temporarily impaired. Impairments are considered to be other-than-temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before the recovery of its cost basis. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income (expense), net in the consolidated statements of operations and other comprehensive income (loss). No other-than-temporary impairment charges were recognized in the fiscal years ended September 30, 2020, 2019, and 2018. All investments whose maturity or sale is expected within one year are classified as “current” on the consolidated balance sheets. All other securities are classified as long-term on the consolidated balance sheets.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful AccountsTrade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected.
Property and Equipment	Property and EquipmentProperty and equipment are carried at cost.
Long-Lived Assets	Long-Lived AssetsThe Company evaluates the carrying value of long-lived assets, including license agreements and other intangible assets, when events and circumstances indicate that these assets may be impaired or in order to determine whether any revision to the related amortization periods should be made. This evaluation is based on management’s projections of the undiscounted future cash flows associated with each product or asset. If management’s evaluation indicates that the carrying values of these intangible assets were 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.
Capitalized Software Development Costs	Capitalized Software Development Costs Costs incurred for the development of software that will be sold, leased, or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the fiscal years ended September 30, 2020 and 2019, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material or were not realizable. The Company had no amortization expense from capitalized software costs during the years ended September 30, 2020, 2019, or 2018.
Goodwill and Purchased Intangible Assets	Goodwill and Purchased Intangible Assets The Company’s goodwill and intangible assets resulted from prior acquisitions. Goodwill and intangible assets with indefinite useful lives are not amortized, but are tested for impairment at least annually or as circumstances indicate that their value may no longer be recoverable. In accordance with ASC Topic 350, Intangibles—Goodwill and Other (“ASC Topic 350”), the Company reviews its goodwill and indefinite-lived intangible assets for impairment at least annually in its fiscal fourth quarter and more frequently if events or changes in circumstances occur that indicate a potential reduction in the fair value of its reporting unit and/or its indefinite-lived intangible asset below their respective carrying values. Examples of such events or circumstances include: a significant adverse change in legal factors or in the business climate, a significant decline in the Company’s stock price, a significant decline in the Company’s projected revenue or cash flows, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, or the presence of other indicators that would indicate a reduction in the fair value of a reporting unit. No such events or circumstances have occurred since the last impairment assessment was performed. The Company’s goodwill is considered to be impaired if management determines that the carrying value of the reporting unit to which the goodwill has been assigned exceeds management’s estimate of its fair value. Based on the guidance provided by ASC 350 and ASC Topic 280, Segment Reporting , management has determined that the Company operates in one segment and consists of one reporting unit. Because the Company has only one reporting unit, and because the Company is publicly traded, the Company determines the fair value of the reporting unit based on its market capitalization as it believes this represents the best evidence of fair value. In the fourth quarter of fiscal 2020, management completed its annual goodwill impairment test and concluded that the Company’s goodwill was not impaired. The Company’s conclusion that goodwill was not impaired was based on a comparison of its net assets to its market capitalization. Because the Company determines the fair value of its reporting unit based on its market capitalization, the Company’s future reviews of goodwill for impairment may be impacted by changes in the price of the Company’s common stock, par value $0.001 per share ("Common Stock"). For example, a significant decline in the price of the Common Stock may cause the fair value of its goodwill to fall below its carrying value. Therefore, the Company cannot assure that when it completes its future reviews of goodwill for impairment, a material impairment charge will not be recorded.
Other Borrowings	Other BorrowingsThe Company has certain loan agreements with Spanish government agencies which were assumed when the Company acquired ICAR Vision Systems, S.L. (“ICAR”). These agreements have repayment periods of five
Guarantees	Guarantees In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC Topic 460, Guarantees (“ASC 460”), except for standard indemnification and warranty provisions that are contained within many of the Company’s customer license and service agreements and certain supplier agreements, and give rise only to the disclosure requirements prescribed by ASC 460. Indemnification and warranty provisions contained within the Company’s customer license and service agreements and certain supplier agreements are generally consistent with those prevalent in the Company’s industry. The Company has not historically incurred significant obligations under customer indemnification or warranty provisions and does not expect to incur significant obligations in the future. Accordingly, the Company does not maintain accruals for potential customer indemnification or warranty-related obligations.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. Management evaluates the available evidence about future taxable income and other possible sources of realization of deferred tax assets. The valuation allowance reduces deferred tax assets to an amount that represents management’s best estimate of the amount of such deferred tax assets that more likely than not will be realized. See Note 8 of the consolidated financial statements for additional details. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters in income tax expense. See Note 8 of the consolidated financial statements for additional details.
Stock-Based Compensation	Stock-Based Compensation The Company issues RSUs, stock options, performance options, and Senior Executive Long-Term Incentive Restricted Stock Units (“Senior Executive Performance RSUs”) as awards to its employees. Additionally, eligible employees may participate in the Company’s ESPP. Employee stock awards are measured at fair value on the date of grant and expense is recognized using the straight-line single-option method in accordance with FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). Forfeitures are recorded as they occur. The Company assigns fair value to RSUs based on the closing stock price of its Common Stock on the date of grant. The Company estimates the fair value of stock options and ESPP shares using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected life of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.
Advertising Expense	Advertising ExpenseAdvertising costs are expensed as incurred
Research and Development	Research and Development Research and development costs are expensed in the period incurred.
Segment Reporting	Segment Reporting FASB ASC Topic 280, Segment Reporting , requires the use of a management approach in identifying segments of an enterprise. During the fiscal year ended September 30, 2020, management determined that the Company has only one operating segment: the development, sale, and service of proprietary software solutions related to mobile imaging.
Comprehensive Income (Loss)	Comprehensive Income (Loss)Comprehensive income (loss) consists of net income (loss), unrealized gains and losses on available-for-sale securities, and foreign currency translation adjustments.
Recently Adopted Accounting Pronouncements, Changes in Significant Accounting Policy and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Incom e, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Jobs Act”). The Company elected not to reclassify the stranded tax effects to retained earnings as they were not material the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 and its related amendments (collectively, known as “ASC 842”) which require lessees to record most leases on the balance sheet but recognize expenses in the income statement in a manner similar to previous guidance. The way in which entities classify leases determines how to recognize lease-related revenue and expenses. The Company adopted ASC 842 as of October 1, 2019 using the optional transition method and will not adjust the comparative period financial statements for the effects of the new standard or make the new, expanded required disclosures for periods prior to the adoption date. Accordingly, the results for the twelve months ended September 30, 2019 continue to be reported under the accounting guidance, ASC Topic 840, Leases (“ASC 840”), in effect for that period. The Company elected to use the package of practical expedients to not reassess: (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases, and (iii) initial direct costs for any existing leases. The Company also elected the practical expedient not to separate the non-lease components of a contract from the lease component to which they relate. In addition, the Company made an accounting policy election that will keep leases with an initial term of twelve months or less off the consolidated balance sheet. The adoption of ASC 842 had a material impact on the consolidated balance sheet as of October 1, 2019, and resulted in the recognition of $8.2 million of lease liabilities and $6.8 million of right-of-use (“ROU”) assets for those leases classified as operating leases. The adoption of ASC 842 did not have a material impact on the Company’s consolidated statements of operations and other comprehensive income (loss) or consolidated statements of cash flows. See Note 9 of the consolidated financial statements for additional details. Change in Significant Accounting Policy Except for the changes below, the Company has consistently applied the accounting policies to all periods presented in its consolidated financial statements. The details of the significant changes and quantitative impact of the changes are disclosed below. Leases The Company determines if an arrangement is a lease at inception in accordance with ASC 842. The lease term begins on the commencement date, which is the date the Company takes possession of the property, and may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease term is used to determine lease classification as an operating or finance lease and is used to calculate straight-line expense for operating leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make payments arising from the lease. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes, which are comprised of real estate leases and auto leases. ROU assets and lease liabilities are recognized at commencement date based upon the present value of lease payments over the lease term. ROU assets also include prepaid lease payments and exclude lease incentives received. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. Since the Company’s leases do not typically provide an implicit rate, the Company uses its incremental borrowing rate based upon the information available at commencement date of each lease. The determination of the incremental borrowing rate requires judgment. The Company determines the incremental borrowing rate using the Company’s current secured borrowing rate. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of twelve months or less are not recorded on the consolidated balance sheet; instead, lease payments are recognized as lease expenses on a straight-line basis over the lease term. See Note 9 of the consolidated financial statements for additional details. Operating lease assets and liabilities are recognized for leases with lease terms greater than 12 months based on the present value of the future lease payments over the lease term at the commencement date. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheet. Operating leases are included in Right-of-use-assets, Lease liabilities, current portion and Lease liabilities, non-current portion on our consolidated balance sheet. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such option. We account for substantially all lease and related non-lease components together as a single lease component. Operating lease expense is recognized on a straight-line basis over the lease term. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in an interim period. The Company is currently in the process of evaluating the potential impact of adoption of this updated authoritative guidance on the consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (ASC 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which requires hosting arrangements that are service contracts to follow the guidance for internal-use software to determine which implementation costs can be capitalized. ASU 2018-15 is effective either prospectively or retrospectively for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company does not expect the adoption of ASU 2018-15 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), to eliminate, add, and modify certain disclosure requirements for fair value measurements. Entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for annual and interim periods beginning after December 15, 2019, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates Step 2 of the goodwill impairment test that had required a hypothetical purchase price allocation. Rather, entities should apply the same impairment assessment to all reporting units and recognize an impairment loss for the amount by which a reporting unit’s carrying amount exceeds its fair value, without exceeding the total amount of goodwill allocated to that reporting unit. Entities will continue to have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 will be effective prospectively for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires entities to use a Current Expected Credit Loss model which is a new impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost. The entity’s estimate would consider relevant information about past events, current conditions and reasonable and supportable forecasts. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 31, 2019 with early adoption permitted for annual reporting periods beginning after December 31, 2018. The Company does not expect the adoption of ASU 2016-13 to have a material impact on its consolidated financial statements. No other new accounting pronouncement issued or effective during the year ended September 30, 2020 had, or is expected to have, a material impact on the Company’s consolidated financial statements.
