Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of the Company and all entities where it has a controlling financial interest and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect amounts reported in the financial statements and notes thereto. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may differ from these estimates. Estimates are associated with recording accounts receivable, inventories, goodwill, intangible assets other than goodwill, contingent consideration liabilities related to business combinations, long-lived assets, derivative financial instruments, deferred income taxes, warranty obligations, revenue over time, stock-based compensation expense, and other accounts. The Company assesses the estimates on an ongoing basis and records changes in estimates in the period they occur and become known. Business Combinations The Company accounts for business acquisitions using the purchase method of accounting, in accordance with which, assets acquired (including identifiable intangible assets), and liabilities assumed are recorded at their respective fair values at the acquisition date. The fair value of the consideration paid, including contingent consideration, is assigned to the assets acquired and liabilities assumed based on their respective fair values. Goodwill represents the excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed. Significant judgment is used in determining fair values of assets acquired and liabilities assumed and contingent consideration, as well as identified intangible assets and their estimated useful lives. Fair value and useful life determinations may be based on valuations that utilize among other factors, estimates of revenue growth rates, operating expenses, integration costs, obsolescence factors, future expected cash flows and discount rates attributable to completed technology and other acquired intangible assets. When estimating the assumptions to be used in the valuation, the Company includes a consideration of current industry information, market and economic trends, historical results of the acquired business, and other relevant factors. These assumptions are forward-looking and could be affected by future economic and market conditions. Adjustments to fair values of assets and liabilities made after the end of the measurement period are recorded within our operating results. Changes in the fair value of contingent consideration resulting from a change in the underlying inputs are recognized in results of operations until the arrangement is settled. Foreign Currency Translation Certain transactions of the Company and its subsidiaries are denominated in currencies other than their functional currency. Foreign currency exchange gains (losses) generated from the settlement and remeasurement of these transactions are recognized in earnings and presented within “Other income (expense)” in the Company’s Consolidated Statements of Operations. Net foreign currency transaction and remeasurement losses totaled $4.2 million, $1.7 million and $1.8 million for the fiscal years ended September 30, 2023, 2022 and 2021, respectively. The determination of the functional currency of the Company’s subsidiaries is based on their financial and operational environment and is the local currency of the Company’s foreign subsidiaries. The subsidiaries’ assets and liabilities are translated into the reporting currency at period-end exchange rates, while revenue, expenses, gains and losses are translated at the average exchange rates during the period. Gains and losses from foreign currency translations are recorded in “Accumulated other comprehensive income (loss)” in the Company’s Consolidated Balance Sheets and presented as “Foreign currency translation adjustments” in the Company’s Consolidated Statements of Comprehensive Income. The semiconductor automation business had foreign operations which had a cumulative translation adjustment balance of $16.6 million at the date of disposal of this business. This amount was removed from “Accumulated other comprehensive income (loss)” in the Company’s Consolidated Balance Sheet during the three months ended March 31, 2022, and included within the gain on the sale of the semiconductor automation business in “Income (loss) from discontinued operations, net of tax” in the Company’s Consolidated Statement of Operations. As a result, the Company presented a $16.6 million reclassification adjustment in “Accumulated other comprehensive income (loss)” in the Company’s Consolidated Balance Sheet at September 30, 2022. ​ Derivative Financial Instruments The Company has transactions and balances denominated in currencies other than the functional currency of the transacting entity. Most of these transactions carry foreign exchange risk in Germany, the United Kingdom and China. The Company enters into foreign exchange contracts to reduce its exposure to currency fluctuations. The arrangements typically mature in three months or less and they do not qualify for hedge accounting. Net gains and losses related to foreign exchange contracts are recorded as a component of “Other income (expense)” in the accompanying Consolidated Statements of Operations. The fair values of the forward contracts are recorded in the accompanying Consolidated Balance Sheets as “Prepaid expenses and other current assets” and “Accrued expenses and other current liabilities”. Foreign exchange contract assets and liabilities are measured and reported at fair value based on observable market inputs and classified within Level 2 of the fair value hierarchy described below due to a lack of an active market for these contracts. ​ All derivatives, whether designated as a hedging relationship or not, are recorded in the Consolidated Balance Sheets at fair value. The accounting for changes in fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the Company must designate the hedging instrument as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation based on the exposure being hedged. Certain derivatives held by the Company are not designated as hedges but are used in managing exposure to changes in foreign exchange rates. ​ A fair value hedge is a derivative instrument designated for the purpose of hedging the exposure to changes in fair value of an asset or a liability resulting from a particular risk. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are both recognized in the results of operations and presented in the same caption in the Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income. A cash flow hedge is a derivative instrument designated for the purpose of hedging the exposure to variability in future cash flows resulting from a particular risk. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in accumulated other comprehensive income (loss) and recognized in the results of operations when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in the results of operations. A hedge of a net investment in a foreign operation is achieved through a derivative instrument designated for the purpose of hedging the exposure of changes in value of investments in foreign subsidiaries. If the derivative is designated as a hedge of a net investment in a foreign operation, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income (loss) as a part of the foreign currency translation adjustment. Ineffective portions of net investment hedges are recognized in the results of operations. For derivative instruments not designated as hedging instruments, changes in fair value are recognized in the Consolidated Statements of Operations as gains or losses consistent with the classification of the underlying risk. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash deposits and cash equivalents, marketable securities, derivative instruments, and accounts receivable. All of the Company’s cash and cash equivalents, restricted cash, marketable securities and derivative instruments are maintained by major financial institutions. The Company invests cash not used in operations in investment grade, high credit quality securities in accordance with the Company’s investment policy which provides guidelines and limits regarding investments type, concentration, credit quality and maturity terms aimed at maintaining liquidity and reducing risk of capital loss. The Company regularly monitors the creditworthiness of its customers and believes that it has adequately provided for exposure to potential credit losses. The Company’s ten largest customers accounted for approximately 30%, 20% and 19% of its consolidated revenue for the fiscal years ended September 30, 2023, 2022 and 2021, respectively. One customer accounted for more than 10% of the Company’s consolidated revenue for fiscal year 2023. This customer is related to the Life Science Products segment and is a distributor shipping to end users in approximately 50 countries. No customers accounted for more than 10% of the Company’s consolidated revenue for fiscal years 2022 and 2021. Marketable Securities The Company invests in marketable securities that are classified as available-for-sale and records them at fair value in the Consolidated Balance Sheets. Marketable securities reported as current assets represent investments that mature within one year from the balance sheet date. Long-term marketable securities represent investments with maturity dates greater than one year from the balance sheet date. Unrealized gains and losses are excluded from earnings and reported as a separate component of “Accumulated other comprehensive income (loss)” in the Consolidated Balance Sheets until the security is sold or matures. Gains or losses realized from sales of marketable securities are computed based on the specific identification method and recognized as a component of “Other income (expense)” in the accompanying Consolidated Statements of Operations. The Company reviews the marketable securities for impairment at each reporting date to determine if any of the securities have experienced an other-than-temporary decline in fair value. The Company considers factors, such as the length of time and extent to which the market value has been less than the cost, the financial condition and near-term prospects of the issuer, the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of its amortized cost basis. If the Company believes that an other-than-temporary decline in fair value has occurred, it writes down the investment to its fair value and recognizes the credit loss in earnings and the non-credit loss in accumulated other comprehensive income (loss). Fair Value Measurement The Company measures certain financial assets and liabilities, including cash equivalents, available-for-sale securities, accounts receivable, accounts payable, contingent consideration liability, and derivative instruments at fair value. The Company applies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following levels of inputs may be used to measure fair value:
| ● | Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible as of the reporting date. Active markets are those in which transactions for the asset and liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. The fair value hierarchy gives the highest priority to Level 1 inputs.
| ● | Level 2: Observable inputs other than prices included in Level 1, including quoted prices for similar assets or liabilities in active markets and quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| ● | Level 3: Unobservable inputs that are significant to the fair value of the assets or liabilities and reflect an entity’s own assumptions in pricing assets or liabilities since they are supported by little or no market activity.
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, as well as considering counterparty credit risk in its assessment of fair value. The Company measures certain assets, including the cost and equity method investments, at fair value on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. The fair values of these investments are determined based on valuation techniques using the best information available, and may include quoted market prices, market comparable prices, and discounted cash flow projections. An impairment charge is recorded when the cost of the investment exceeds its fair value and this condition is determined to be other-than-temporary Cash and Cash Equivalents, and Restricted Cash Cash and cash equivalents consist of cash and highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash. Cash equivalents are reported at fair value. The Company classifies long-term restricted cash balances within “Other assets” on the accompanying Consolidated Balance Sheets based upon the term of the remaining restrictions. Accounts Receivable and Allowance for Expected Credit Losses Trade accounts receivable do not bear interest and are recorded at the invoiced amount. The Company maintains an allowance for expected credit losses representing its best estimate of expected credit losses related to its existing accounts receivable and their net realizable value. The Company determines the allowance based on several factors, including an evaluation of customer credit worthiness, the age of the outstanding receivables, economic trends, historical experience and other information over the payment periods. The Company reviews and adjusts the allowance for expected credit losses on a quarterly basis. Accounts receivable balances are written off against the allowance for expected credit losses when the Company determines that the balances are not recoverable. Provisions for expected credit losses are recorded in “Selling, general and administrative” expenses in the Consolidated Statements of Operations. The Company does not have any off-balance-sheet credit exposure related to its customers. Inventories Inventories are stated at the lower of cost or net realizable value determined on a first-in, first-out basis and include the cost of materials, labor and manufacturing overhead. The Company reports inventories at their net realizable value and provides reserves for excess, obsolete or damaged inventory based on changes in customer demand, technology and other economic factors. Fixed Assets, Intangible Assets and Impairment of Long-lived Assets Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation expense is computed based on the straight-line method and charged to results of operations to allocate the cost of the assets over their estimated useful lives, as follows: ​
​ | ​ | ​
Buildings |  | 10 - 40 years
Computer equipment and software |  | 3 - 5 years
Machinery and equipment |  | 2 - 7 years
Furniture and fixtures |  | 5 years
Vehicles |  | 3 - 7 years
​ Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining terms of the respective leases. Equipment used for demonstrations to customers is included in machinery and equipment and depreciated over its estimated useful life. Repair and maintenance costs are expensed as incurred. The Company has developed software for internal use. Internal and external labor costs incurred during the application development stage of a project are capitalized. Costs incurred prior to application development and post implementation are expensed as incurred. Training and data conversion costs are expensed as incurred. Long lived assets and their associated accumulated depreciation are derecognized upon their retirement or at the time of disposal, and the resulting gain or loss is included in the Company’s results of operations. The Company identified finite-lived intangible assets other than goodwill as a result of acquisitions. Finite-lived intangible assets are valued based on estimated future cash flows and amortized over their estimated useful lives based on methods that approximate the pattern in which the economic benefits are expected to be realized. Finite-lived intangibles assets and fixed assets are tested for impairment when indicators of impairment are present. For purposes of this test, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the Company determines that indicators of potential impairment are present, it assesses the recoverability of long-lived asset group by comparing its undiscounted future cash flows to its carrying value, and an impairment loss is recognized in operating results to the extent any finite-lived intangible asset’s carrying value exceeds its calculated fair value. The future cash flow period is based on the future service life of the primary asset within the long-lived asset group. Finite-lived intangible assets are amortized over their useful lives, as follows: ​
​ | ​ | ​
Trademarks |  | 5 - 13 years
Patents |  | 8 years
Completed technology |  | 7 - 15 years
Customer relationships |  | 10 - 16 years
Non-competition agreements |  | 5 years
​ Leases The Company has operating leases for real estate and non-real estate and finance leases for non-real estate. The classification of a lease as operating or finance and the determination of the right-of-use asset (“ROU asset”) and lease liability are determined at lease inception. The ROU asset represents the Company’s right to use an underlying asset for the lease term and the lease liability represents the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, an incremental borrowing rate is used based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The Company’s lease agreements may contain lease and non-lease components. Non-lease components primarily include payments for maintenance and utilities. Fixed payments for non-lease components are combined with lease payments and accounted for as a single lease component which increases the amount of the ROU asset and liability. The ROU asset for operating leases is included within “Other assets” and the ROU asset for finance leases is included within “Property, plant and equipment, net” in the Consolidated Balance Sheets. The short-term lease liabilities for both operating leases and finance leases are included within “Accrued expenses and other current liabilities” in the Consolidated Balance Sheets. The long-term lease liabilities for operating leases and finance leases are included within “Long-term operating lease liabilities”, and “Other long-term liabilities”, respectively, in the Consolidated Balance Sheets. Goodwill Goodwill represents the excess of purchase price over the fair value of net tangible and identifiable intangible assets of businesses acquired by the Company. Goodwill is tested for impairment annually or more often if impairment indicators are present at the reporting unit level. The Company elected April 1st as its annual goodwill impairment assessment date. If the existence of events or circumstances indicates that it is more likely than not that fair values of the reporting units are below their carrying values, the Company performs additional impairment tests during interim periods to evaluate goodwill for impairment. Application of the goodwill impairment test requires significant judgment based on market and operational conditions at the time of the evaluation, including management’s best estimate of future business activity and the related estimates of future cash flows from the reporting units that include the associated goodwill. These periodic evaluations could cause management to conclude that impairment factors exist, requiring an adjustment of these assets to their then-current fair market values. Future business conditions and/or activity could differ materially from the projections made by management which could result in impairment charges. The goodwill impairment test is performed at the reporting unit level. A reporting unit is either an operating segment or one level below it, which is referred to as a “component”. The level at which the impairment test is performed requires an assessment of whether the operations below an operating segment constitute a self-sustaining business, in which case testing is generally performed at this level. The Company first assesses qualitative factors to determine whether the existence of events or circumstances indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines, based on this assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying value, management performs a quantitative goodwill impairment test by comparing the reporting unit’s fair value with its carrying value. An impairment loss is recognized for the amount by which the reporting unit’s carrying value exceeds its fair value, up to the total amount of goodwill allocated to the reporting unit. We determine fair values of our reporting units based on an income approach in accordance with the discounted cash flow method, (the “DCF Method”). The DCF Method is based on projected future cash flows and terminal value estimates discounted to their present values. Terminal value represents the present value an investor would pay on the valuation date for the rights to the cash flows of the business for the years subsequent to the discrete cash flow projection period. We consider the DCF Method to be the most appropriate valuation technique since it is based on management’s long-term financial projections. In addition to determining the fair value of our reporting units based on the DCF Method, we also compare the aggregate values of our net corporate assets and reporting unit fair values to our overall market capitalization and use certain market-based valuation techniques to assess the reasonableness of the reporting unit fair values determined in accordance with the DCF Method. Warranty Obligations The Company establishes reserves for estimated costs of product warranties based on historical information. Product warranty reserves are recorded at the time product revenue is recognized, and retrofit accruals are recorded at the time retrofit programs are established. The Company’s warranty obligation is affected by product failure rates, utilization levels, material usage, service delivery costs incurred in correcting a product failure and supplier warranties on parts delivered by the Company. Revenue Recognition The Company generates revenue from the following sources: ​
| ● | Products, including sales of automated cold sample management systems, vaccine cold storage and transport systems, consumables, instruments, spare parts, and software.
| ● | Services, including repairs, upgrades, diagnostic support, installation, as well as biological sample services such as DNA sequencing, gene synthesis, molecular biology, bioinformatics, biological sample storage, sample acquisition, and other support services.
The Company recognizes revenue for the transfer of such promised products or services to customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those products or services. Under ASC 606, Revenue from Contracts with Customers (“ASC 606”), revenue is recognized when, or as, the transfer of control of the underlying performance obligation occurs. To determine the amount of consideration the Company expects to be entitled to and whether transfer of control has occurred, the Company applies the following five-step model: ​
| ● | Identify the contract with a customer. Contracts are accounted for when approval and commitment has been received from both parties, the rights of each party are identified, payment terms are identified, the contract has commercial substance and collectability of the consideration to which the Company is entitled is probable. Contracts are generally evidenced through receipt of an approved purchase order or execution of a binding arrangement and can be both short and long-term. Long-term contracts within the segments relate to the sale of products with attached service-type warranty contracts that generally have a stated contract term that is greater than one year. Contracts may contain acceptance provisions where the Company is required to obtain technical acceptance from the customer upon completion of installation services and evidence of the system’s functional performance within the customer’s operating environment. The Company has concluded that acceptance criteria within its contracts can be objectively evaluated and will not impact the Company’s transfer of control assessment under ASC 606.
| ● | Identify the performance obligations in the contract. Performance obligations include the sale of products and services. Certain customer arrangements related to the sale of automated cold sample management systems generally include more than one performance obligation and may include a combination of goods and or services, such as products with installation services or service-type warranty obligations. These contracts include multiple promises and as a result, the Company is required to evaluate each promise and determine whether the promise qualifies as a performance obligation within the contract. Contracts may contain the option to acquire additional products or services at defined prices. The Company reviews the pricing of these options to determine whether the option would exist independently of the current contract. If the pricing of contract options provides a material right to the customer that it would not receive without entering into the current contract, the Company accounts for the option as a separate performance obligation.
| ● | Determine the transaction price. The transaction price of the Company’s contracts with its customer is generally fixed, based on the amounts to be contractually billed to the customer. Although uncommon, certain contracts may contain variable consideration in the form of customer allowances and rebates that consist primarily of retrospective volume-based discounts and other incentive programs. Variable consideration is estimated at contract inception and included in the transaction price if it is probable that a subsequent change in the estimate would not result in a significant revenue reversal. The period between transfer of control of the
|  | performance obligations within a customer contract and timing of payment is generally within one year. As a result, the Company’s contracts typically do not include significant financing components.
| ● | Allocate the transaction price to the performance obligations in the contract. For customer contracts that contain more than one performance obligation, the Company allocates the total transaction consideration to each performance obligation based on the relative stand-alone selling price of each performance obligation within the contract. The Company relies on either observable standalone sales or an expected cost-plus margin approach to determine the standalone selling price of offerings, depending on the nature of the performance obligation. Performance obligations whose standalone selling price is estimated using an expected cost-plus margin approach relate to the sale of customized automated cold sample management systems, services, and service-type warranties.
| ● | Recognize revenue when or as the Company satisfies a performance obligation. The Company satisfies its performance obligations by transferring a product or service either at a point in time or over time, when the transfer of control of the underlying performance obligation has occurred. Control is evidenced by the customer’s ability to direct the use of and obtain substantially all the remaining benefits from the performance obligation. Revenue from third-party sales for which the Company does not meet the criteria for gross revenue recognition is recognized on a net basis. All other revenue is recognized on a gross basis. The Company excludes from the transaction price all sales taxes assessed by governmental authorities and as a result, revenue is presented net of tax.
As a result of applying this five-step model under ASC 606, the Company recognizes revenues from its sale of products and services as follows: ​
| ● | Products: Revenue from the sale of standard products is recognized upon their transfer of control to the customer, which is considered complete at either the time of shipment or arrival at destination, based on the agreed upon terms within the contract. The Company’s payment terms for the sale of standard products are typically 30 to 60 days.
Revenue from the sales of certain products that involve significant customization, which include primarily automated cold sample management systems is recognized over time as the asset created by the Company’s performance does not have alternative use to the Company and an enforceable right to payment for performance completed to date is present. The Company recognizes revenue as work progresses based on a percentage of actual labor hours incurred on the project to-date and total estimated labor hours expected to be incurred on the project. The selection of the method to measure progress towards completion requires judgment. The Company has concluded that using the percentage of labor hours incurred to estimated labor hours needed to complete the project most appropriately depicts the Company’s efforts towards satisfaction of the performance obligation. The Company develops profit estimates for long-term contracts based on total revenue expected to be generated from the project and total costs anticipated to be incurred in the project. These estimates are based on a number of factors, including the degree of required product customization and the work required to be able to install the product in the customer’s existing environment, as well as the Company’s historical experience, project plans and an assessment of the risks and uncertainties inherent in the contract related to implementation delays or performance issues that may or may not be within the Company’s control. The Company estimates a loss on a contract by comparing total estimated contract revenue to the total estimated contract costs and recognizes a loss during the period in which it becomes probable and can be reasonably estimated. The Company reviews profit estimates for long-term contracts during each reporting period and revises the estimate based on changes in circumstances. Revenue for certain arrangements that involve significant product customization but do not provide the Company with an enforceable right to payment for performance completed to date are recognized at a point in time, upon completion or substantial completion of the project, provided transfer of control has occurred. The project is considered substantially complete when the Company receives acceptance from the customer and remaining tasks are perfunctory or inconsequential and in control of the Company. Generally, the terms of long-term contracts provide for progress billings based on completion of milestones or other defined phases of work. In certain instances, payments collected from customers in advance of recognizing the related revenue are recorded and presented as contract liabilities within “Deferred revenue” on the Company’s Consolidated Balance Sheet. Additionally, due to certain billing constraints within contracts, the customer may retain a portion of the contract price until completion of the contract. In these contracts, an unbilled receivable is recorded when revenue recognized may exceed billings, which the Company presents as a contract asset on the balance sheet, which is included within the “Prepaid expenses and other current assets” on the Company’s Consolidated Balance Sheet.
| ● | Services: Service revenue is generally recognized ratably over time or on an output method, as the customer simultaneously receives and consumes the benefit of these services as they are performed. Payments related to service-type warranties may be made up front or proportionally over the contract term. Revenue for sample management and storage are recognized over the period the services are rendered or samples are stored. Revenue from genomic services is recognized over time and is based upon the fact that transfer of control takes place over time as determined using the input method of costs incurred. Payment due or received from the customers prior to rendering the associated services are recorded as a contract liability.
Government Assistance The Company receives government assistance from various domestic and foreign, local, regional and national governments which vary in size and duration in the form of cash grants or refundable tax credits. The government assistance typically specifies conditions that must be met in order for it to be earned, such as employee retention targets, completion of employee training, or the construction or acquisition of property and equipment and are often time bound. If conditions are not satisfied or if the duration period for the arrangement is not met, the government assistance is often subject to reduction, repayment, or termination. The Company’s policy is to recognize a benefit in the Consolidated Statements of Operations in “Other, net” over the life of the asset or duration of the program when the Company has reasonable assurance that it will comply with the conditions under the government assistance and the government assistance will be received, refundable tax credits may also result in a reduction in “Accrued income taxes payable” in the Consolidated Balance Sheets. If government assistance is received or is probable of receipt and the amount is determinable by the Company in advance of completion of the conditions, the government assistance is recognized in “Accrued expenses and other current liabilities” or “Other long-term liabilities” in the Consolidated Balance Sheets, as appropriate. In fiscal year 2023, approximately $4.3 million of government assistance was recognized in “Other, net” and approximately $0.9 million was recognized as a reduction to “Cost of Revenue – Products” in the Company’s Consolidated Statement of Operations. The Company also received advance cash government assistance of $6.6 million, of which $4.7 million is recognized within “Other long-term liabilities”, and $1.9 million is recognized within “Accrued expenses and other current liabilities” in the Consolidated Balance Sheet. Furthermore, the Company anticipates receipt of $0.6 million of additional government assistance, recorded within “Prepaid expenses and other current assets” in the Consolidated Balance Sheet. Research and Development Expense Research and development costs are expensed as incurred. Research and development costs consist primarily of personnel expenses related to development of new products, as well as enhancements and engineering changes to existing products and development of hardware and software components. Stock-Based Compensation The fair value of restricted stock units is determined based on the number of shares granted and the closing price of the Company’s common stock quoted on the Nasdaq Stock Market on the date of grant. For awards that vest based on service conditions, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period. For awards that vest subject to performance conditions, the Company recognizes stock-based compensation expense ratably over the performance period if it is probable that performance condition will be met and adjusts for the percentage of shares probable of achieving the performance goals. Each quarter, management assesses the probability of achieving the performance goals. The Company makes estimates of stock award forfeitures and the number of awards expected to vest. The Company considers many factors in developing forfeiture estimates, including award types, employee classes and historical experience. Current estimates may differ from actual results and future changes in estimates. Income Taxes The Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, as well as operating loss and tax credit carryforwards. The Company’s Consolidated Financial Statements contain certain deferred tax assets that were recorded as a result of operating losses, as well as other temporary differences between financial and tax accounting. A valuation allowance is established against deferred tax assets if, based upon the evaluation of positive and negative evidence and the extent to which that evidence is objectively verifiable, it is more likely than not that some or all of the deferred tax assets will not be realized. Significant management judgment is required in determining the Company’s income tax (benefit) expense, the Company’s deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. The Company evaluates the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. The calculation of the Company’s income tax liabilities involves consideration of uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon an audit conducted by taxing authorities, including resolution of related appeals or litigation processes, if any. If the Company determines that a tax position will more likely than not be sustained, the second step requires the Company to estimate and measure the tax benefit as the largest amount that is more likely than not to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as the Company must determine the probability of various possible outcomes. The Company re-evaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors, such as changes in facts or circumstances, tax law, new audit activity and effectively settled issues. Determining whether an uncertain tax position is effectively settled requires judgment. A change in recognition or measurement may result in the recognition of a tax benefit or an additional charge to the tax expense. Net Income (Loss) per Share Basic income or loss per share is determined by dividing net income by the weighted average common shares outstanding during the period. Diluted income or loss per share is determined by dividing net income by diluted weighted average shares outstanding during the period. Diluted weighted average shares reflect the dilutive effect, if any, of potential common shares. To the extent their effect is dilutive, employee equity awards and other commitments to be settled in common stock are included in the calculation of diluted income or loss per share based on the treasury stock method. Potential common shares are excluded from the calculation of dilutive weighted average shares outstanding if their effect would be anti-dilutive at the balance sheet date based on a treasury stock method or due to a net loss. Recently Adopted Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The ASUs provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The provisions of the ASUs were only available until December 31, 2022, when the reference rate replacement activity was expected to be completed. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, extending the relief offered in this series of ASUs through December 31, 2024. The Company adopted this guidance for the fiscal year ended September 30, 2023. There is no significant accounting impact on the Company’s consolidated financial statements and related disclosures as a result of the adoption of these ASUs. ​ In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) – Disclosures by Business Entities about Government Assistance. The amendment in this ASU requires disclosures to increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. This ASU is effective for annual periods beginning after December 15, 2021. The Company adopted this guidance for the fiscal year ended September 30, 2023 on a prospective basis. The adoption of the ASU did not impact the Company’s recording or reporting of such amounts in the Company’s consolidated financial statements. See “Government Assistance” for the required disclosures resulting from adoption of this ASU. In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. This ASU is effective for annual periods beginning after December 15, 2021. The adoption of this ASU on October 1, 2022 did not have a material impact on the Company’s consolidated financial statements or disclosures.
