The accompanying Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company applies the equity method of accounting to investments that provide it with the ability to exercise significant influence over the entities in which it lacks controlling financial interest and is not a primary beneficiary.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Significant estimates are associated with recording accounts receivable, inventories, goodwill, intangible assets other than goodwill, long-lived assets, derivative financial instruments, deferred income taxes, warranty obligations, revenue recognized in accordance with the percentage of completion method, and stock-based compensation expense. The Company assesses the estimates on an ongoing basis and records changes in estimates in the period they occur and become known. Actual results could differ from these estimates.

The Company accounts for business acquisitions using the acquisition method of accounting, in accordance with which assets acquired 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 excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed.

Significant judgments are used in determining fair values of assets acquired and liabilities assumed, as well as intangibles. Fair value and useful life determinations are based on, among other factors, estimates of future expected cash flows and appropriate discount rates used in computing present values. These judgments may materially impact the estimates used in allocating acquisition date fair values to assets acquired and liabilities assumed, as well as the Company’s current and future operating results. Actual results may vary from these estimates which may result in adjustments to goodwill and acquisition date fair values of assets and liabilities during a measurement period or upon a final determination of asset and liability fair values, whichever occurs first. Adjustments to fair values of assets and liabilities made after the end of the measurement period are recorded within the Company’s operating results.

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 expenses, net” in the Company’s Consolidated Statements of Operations. Net foreign currency transaction and remeasurement losses totaled $1.8 million, $3.3 million and $2.3 million for the fiscal years ended September 30, 2019, 2018 and 2017, 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 all 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” in the Company’s Consolidated Balance Sheets and presented as a component of comprehensive income in the Company’s Consolidated Statements of Comprehensive Income.

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 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 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.

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, cash equivalents, 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 28%, 34% and 35% of its consolidated revenue for the fiscal years ended September 30, 2019, 2018 and 2017, respectively. No customers accounted for more than 10% of the Company’s consolidated revenue for fiscal years 2019, 2018 and 2017.

The Company’s financial instruments consist of cash and cash equivalents, marketable securities, derivative instruments, the term loan, accounts receivable, and accounts payable. Marketable securities and derivative instruments are measured at fair value based on quoted market prices or observable inputs other than quoted market prices for identical or similar assets or liabilities. The carrying amounts of cash, cash equivalents, accounts receivable and accounts payable approximate their fair value due to their short-term nature.

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. At September 30, 2019 and 2018, cash equivalents were $16.2 million and $50.6 million, respectively. Cash equivalents are reported at fair value.

We classify certain restricted cash balances within prepaid expenses and other current assets on the accompanying consolidated balance sheets based upon the term of the remaining restrictions.

Trade accounts receivable do not bear interest and are recorded at the invoiced amount. The Company maintains an allowance for doubtful accounts representing its best estimate of probable credit losses related to its existing accounts receivable and their net realizable value. The Company determines the allowance based on a number of factors, including an evaluation of customer credit worthiness, the age of the outstanding receivables, economic trends and historical experience. The Company reviews its allowance for doubtful accounts on a quarterly basis and adjusts the balance based on the Company’s estimates of the receivables’ recoverability in the period the changes in estimates occur and become known. Accounts receivable balances are written off against the allowance for doubtful accounts when the Company determines that the balances are not recoverable. Provisions for doubtful accounts are recorded in "Selling, general and administrative expenses" in the Consolidated Statements of Operations. The Company determines the allowance for sales returns based on its best estimate of probable customer returns. Provisions for sales returns are recorded in "Revenue" in the Consolidated Statements of Operations. The Company does not have any off-balance-sheet credit exposure related to its customers.

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.

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:

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. As of September 30, 2019, and 2018, the Company had cumulative capitalized direct costs of $11.6 million and $5.6 million, respectively, associated with the development of software for its internal use. These capitalized costs are included within "Property, plant and equipment, net" in the accompanying Consolidated Balance Sheets. During fiscal year 2019, the Company capitalized direct costs of $5.1 million associated with the development of software for its internal use.

Cost of disposed assets and the 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. The future cash flow period is based on the future service life of the primary asset within the long-lived asset group. If the carrying value of the long-lived asset group exceeds its future cash flows, the Company determines fair values of the individual net assets within the long-lived asset group to assess potential impairment. If the aggregate fair values of the individual net assets of the group are less than their carrying values, an impairment loss is recognized for an amount in excess of the group’s aggregate carrying value over its fair value. The loss is allocated to the assets within the group based on their relative carrying values, with no asset reduced below its fair value.

Finite-lived intangible assets are amortized over their useful lives, as follows:

Goodwill represents the excess of purchase price over the fair value of net tangible and identifiable intangible assets of the 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 has elected April 1^st 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 assets and 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 additional adjustments and 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.

In accordance with ASC 350, Intangibles- Goodwill and Other (“ASC 350”), 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, it 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.

The Company determines fair values of its reporting units based on an income approach in accordance with the discounted cash flow method (DCF Method). The DCF Method is based on projected future cash flows and terminal value estimates discounted to their present values. Terminal value represents a 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. The observable inputs used in the DCF Method include discount rates set above the Company’s weighted-average cost of capital. The Company derives discount rates that are commensurate with the risks and uncertainties inherent in the respective businesses and its internally developed projections of future cash flows. The Company considers the DCF Method to be the most appropriate valuation technique since it is based on management’s long-term financial projections. Due to the cyclical nature of the semiconductor equipment market, management’s projections as of the valuation date are considered more objective since market metrics of peer companies fluctuate during the cycle. In addition, the Company also compares aggregate values of its net corporate assets and reporting unit

fair values to its overall market capitalization and uses certain market-based valuation techniques to test the reasonableness of the reporting unit fair values determined in accordance with the DCF Method.

The Company records commitment fees and other costs directly associated with obtaining the term loan and line of credit financing as deferred financing costs which are presented as a reduction of Long-term debt on the Consolidated Balance Sheets. Deferred financing costs were $0.9 million and $2.9 million at September 30, 2019 and 2018, respectively. Such costs are amortized over the term of the related financing arrangement and included in “Interest expense” in the accompanying Consolidated Statements of Operations. Amortization expense related to deferred financing costs was $1.1 million and $0.5 million for fiscal years ended September 30, 2019 and 2018, respectively, and was included in interest expense in the accompanying Consolidated Statements of Operations. Please refer to Note 10, “Line of Credit” and Note 11, “Debt” for further information on this arrangement.

The Company offers warranties on the sales of certain of its products and records warranty obligations for estimated future claims at the time revenue is recognized. Warranty obligations are estimated based on historical experience and management’s estimate of the level of future claims.

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:

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 generally upon delivery. Delivery 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 customer 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, 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. Revenue from short-term services, generally related to repair services or upgrades of customer-owned equipment is recognized upon completion of the repair effort and the shipment of the repaired product back to the customer. Payments related to service-type warranties may be made up front or proportionally over the contract term. Payment due or received from the customers prior to rendering the associated services are recorded as a contract liability.

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 Expense

The Company measures stock-based compensation cost at fair value on the grant date and recognizes the expense over the service period for the awards expected to vest. 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 Nasdaq 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 adjusted for the probability percentage 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. Each quarter, the Company assesses the probability of achieving the performance goals. Current estimates may differ from actual results and future changes in estimates.

The following table reflects stock-based compensation expense, excluding amounts related to discontinued operations, recorded during the fiscal years ended September 30, 2019, 2018 and 2017 (in thousands):


	Year Ended September 30,
	2019		2018		2017
Restricted stock units	$	18,276	$	18,081	$	16,056
Employee stock purchase plan		1,203		775		517
Total stock-based compensation expense	$	19,479	$	18,856	$	16,573

Valuation Assumptions for an Employee Stock Purchase Plan

The fair value of shares issued under the employee stock purchase plan is estimated on the commencement date of each offering period using the Black-Scholes option-pricing model with the following weighted average assumptions for the fiscal years ended September 30, 2019, 2018 and 2017:


	Year Ended September 30,
	2019		2018		2017
Risk-free interest rate	2.3	%	1.9	%	0.9	%
Volatility	52	%	46	%	34	%
Expected life	6 months		6 months		6 months
Dividend yield	1.2	%	1.5	%	3.4	%

The risk-free rate is based on the U.S. Treasury yield curve for notes with terms approximating the expected life of the shares granted. The expected stock price volatility is determined based on the Company’s historic stock prices over a period commensurate with the expected life of the shares granted. The expected life represents the weighted average period over which the shares are expected to be purchased. Dividend yields are projected based on the Company’s history of dividend declarations and management’s intention for future dividend declarations.

Restructuring Expenses

The Company records restructuring expenses associated with management-approved restructuring actions, such as consolidation of duplicate infrastructure and reduction in force, to streamline its business operations and improve profitability and competitiveness. Restructuring expenses include severance costs, contract termination costs to vacate facilities and consolidate operations, and other costs directly associated with restructuring actions. The Company records severance and other employee termination costs associated with restructuring actions when it is probable that benefits will be paid and the amounts can be reasonably estimated. The rates used in determining restructuring liabilities related to severance costs are based on existing plans, historical experience and negotiated settlements.

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 provision, 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 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 or an examination 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 has to 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 provision.

Earnings Per Share

Basic income per share is determined by dividing net income by the weighted average common shares outstanding during the period. Diluted income 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 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 Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), an amendment of the FASB ASC. In accordance with the provisions of the newly issued guidance, a lessee should recognize at the inception of the arrangement a right-of-use asset and a corresponding lease liability initially measured at the present value of lease payments over the lease term. For finance leases, interest on a lease liability should be recognized separately from the amortization of the right-of-use asset, while for operating leases, total lease costs are recorded on a straight-line basis over the lease term. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying assets to forgo a recognition of right-of-use assets and corresponding lease liabilities and record a lease expense on a straight-line basis. Entities should determine at the inception of the arrangement whether a contract represents a lease or contains a lease which is defined as a right to control the use of identified property for a period of time in exchange for consideration. Additionally, entities should separate the lease components from the non-lease components and allocate the contract consideration on a relative standalone price basis in accordance with provisions of ASC 606. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 and should be adopted via a modified retrospective approach with certain optional practical expedients that entities may elect to apply. The Company will adopt the provisions of this ASU during the first quarter of fiscal year 2020 and not recast prior periods. The Company expects to record a right-of-use asset and lease liability of approximately $31 million to $36 million as of October 1, 2019. The Company does not expect the adoption of this standard to have a significant impact on its Consolidated Statements of Operations or Consolidated Statements of Cash Flows.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), which amends ASC 326 to add, remove, and clarify disclosure requirements related to credit losses of financial instruments. The new guidance introduces a new "expected loss" impairment model which applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities and other financial assets. Entities are required to estimate expected credit losses over the life of financial assets and record an allowance against the assets’ amortized cost basis to present them at the amount expected to be collected. Additionally, the guidance amends the impairment model for available for sale debt securities and requires entities to determine whether all or a portion of the unrealized loss on such debt security is a credit loss. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. The standard should be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period

in which the guidance is effective. The Company expects to adopt the guidance during the first quarter of fiscal year 2021 and is currently evaluating the impact of this guidance on its financial position and results of operations.

In March 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which amends ASC 220 to add, remove, and clarify disclosure requirements related to reporting comprehensive income. This ASU gives entities the option to reclassify tax effects recorded in accumulated other comprehensive income as a result of tax reform to retained earnings. The entities have the option to apply the guidance retrospectively or in the period of adoption. The guidance requires entities to make new disclosures, regardless of whether they elect to reclassify tax effects. The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption in any period is permitted. The Company expects to adopt the guidance during the first quarter of fiscal year 2020 and is evaluating the effect that ASU 2018-02 will have on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which amends ASC 820 to add and remove disclosure requirements related to fair value measurement. The amendments include new disclosure requirement for changes in unrealized gains or losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The amendments eliminated disclosure requirements for amount of and reasons for transfers between Level 1 and Level 2, valuation processes for Level 3 fair value measurements, and policy for timing of transfers between levels of the fair value hierarchy. In addition, the amendments modified certain disclosure requirement to provide clarification or to promote appropriate exercise of discretion by entities. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework — Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The amendments require additional disclosure for the weighted-average interest crediting rates, a narrative description of the reasons for significant gains and losses, and an explanation of any other significant changes in the benefit obligation or plan assets. The amendment removes disclosure requirement for accumulated other comprehensive income expected to be recognized over the next year, information about plan assets to be returned to the entity, and the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost, and the benefit obligation for postretirement health care benefits. The ASU is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The ASU does not amend the interim disclosure requirements of ASC 715-20. The Company is currently evaluating the impact of this ASU.

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. The provisions may be adopted prospectively or retrospectively. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.

In December 2018, the FASB issued ASU 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors. The amendments create a lessor practical expedient applicable to sales and other similar taxes incurred in connection with a lease and simplify lessor accounting for lessor costs paid by the lessee. The ASU permits lessors to present sales and other similar taxes that arise from a specific leasing transaction on a net basis. It requires lessors to present lessor costs paid by the lessee directly to a third party on a net basis – regardless of whether the lessor knows, can determine or can reliably estimate those costs. It requires lessors to present lessor costs paid by the lessee to the lessor on a gross basis. It clarifies that lessors should recognize variable payments allocable to non-lease components as revenue in accordance with relevant other guidance. The effective date coincides with the effective date of the new leases standard

for companies that have not early adopted. As such, this ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.

In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842) - Codification Improvements, which makes targeted changes to lessor accounting and clarifies interim transition disclosure requirements. The ASU clarifies that companies are exempt from making the interim period transition disclosures required by ASC 250, Accounting Changes and Error Corrections, for the period in which a change in accounting principle is made as a result of adopting ASC 842. This interim period disclosure exemption is consistent with ASC 842, which already allowed companies to exclude the annual effect of the accounting change on income from continuing operations, net income and per-share amounts for periods post-adoption. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which makes targeted changes to standards on credit losses, hedging, and recognizing and measuring financial instruments to clarify them and address implementation issues. The amendments clarify the scope of the credit losses standard and address issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments, among other things. On recognizing and measuring financial instruments, the amendments address the scope of the guidance, the requirement for remeasurement under ASC 820 when using the measurement alternative, certain disclosure requirements and which equity securities have to be remeasured at historical exchange rates. The amendments in ASU 2019-04 related to ASU 2016-01 are effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted if the entity has adopted those standards. The Company is currently evaluating the impact of this ASU.

In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326) - Targeted Transition Relief, which provides transition relief for entities adopting ASU 2016-13. The amendments in ASU 2019-05 allow entities to elect the fair value option on certain financial instruments. ASU 2019-05 amends ASU 2016-13 to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that were previously recorded at amortized cost and are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019-05’s amendments should be applied “on a modified-retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings in the statement of financial position as of the date that an entity adopted the amendments in ASU 2016-13.” Certain disclosures are required. For entities that have not adopted ASU 2016-13, the effective date of ASU 2019-05 will be the same as the effective date of ASU 2016-13 which is for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted if the entity has adopted ASU 2016-13. The Company is currently evaluating the impact of this ASU.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASC 606 which contained new accounting guidance for reporting revenue recognition. The guidance provides for the recognition of revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. In addition, the guidance requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The guidance also specifies the accounting for certain costs to obtain and fulfill a contract, as codified in ASC 340-40 Accounting for Other Assets and Deferred Costs (“ASC 340-40”).

The Company adopted this standard effective October 1, 2018, using the modified retrospective method and has only applied this method to contracts that were not completed as of the effective date and all new contracts initiated on or after the effective date. Results for reporting periods beginning on or after October 1, 2018 are presented under ASC 606, while prior period amounts have not been restated and continue to be reported in accordance with the governing revenue recognition standards applicable to that period.

The impact of the cumulative effect of adopting ASC 606 effective October 1, 2018 on the Company’s Consolidated Balance Sheet is as follows:


	As Reported		Impact of Adopting		As Adopted
	September 30, 2018		ASC 606		October 1, 2018
Prepaid expenses and other current assets	$	31,741	$	350	$	32,091
Prepaid expenses and other current assets - discontinued operations		343		235		578

Other assets		5,294		1,483		6,777

Long-term deferred tax assets		43,798		403		44,201

Deferred revenue		25,884		2,850		28,734
Deferred revenue - discontinued operations		1,052		480		1,532

Accumulated deficit		(994,074)		(859)		(994,933)

Upon adoption of ASC 606, the Company recorded a cumulative effect adjustment of $0.9 million, net of a tax adjustment of $0.4 million, which resulted in an increase to the opening accumulated deficit balance on the Consolidated Balance Sheet, primarily driven by deferral of previously recognized revenue within the Brooks Life Sciences segment, offset by deferral of previously recognized commission expense within the Brooks Life Sciences segment and acceleration of revenue within the Brooks Semiconductor Solutions Group segment.

A portion of the adjustment related to the acceleration of revenue within the Brooks Semiconductor Solutions Group segment resulted from the change in the revenue recognition rules. Upon the adoption of ASC 606, the Company is no longer required to defer revenue in accordance with billing constraints defined in the contract with the customer. The change impacted the Company’s semiconductor contamination control solutions revenue stream as under ASC 606, the Company recognizes revenue in an amount equivalent to the transfer of control that has occurred. (Please refer to Note 19, “Revenue from Contracts with Customers” for further information on when control is transferred). As a result, revenue previously deferred due to the contractual billing restraints that otherwise met the revenue recognition requirements was accelerated into the opening accumulated deficit balance resulting in an increase to accumulated deficit of $0.9 million as of October 1, 2018.

A portion of the adjustment related to the deferral of previously recognized revenue within the Brooks Life Science segment related to fees associated with registration of biological samples. This adjustment is derived from the new requirement to recognize revenue associated with certain sample life cycle management solutions transactions over time under ASC 606, while historically these transactions have been recorded at a point in time. Registration fees for these samples were previously recognized as revenue at a point in time upon completion of the registration and are now required to be recognized ratably over the period of benefit under ASC 606. As a result, upon adopting ASC 606, the Company deferred previously recognized registration fee revenue for contracts not completed as of the effective date. The period of benefit associated with registration fees has been determined to be approximately 24 months resulting in the deferral of revenue historically recognized at a point in time over this period. This change resulted in a decrease to accumulated deficit of $3.1 million as of October 1, 2018.

A portion of the adjustment is related to the deferral of previously recognized commission expense within the Brooks Life Science segment. This portion of the adjustment is derived from the new requirement to recognize the cost to obtain certain transactions over time under ASC 340-40, while historically this expense has been recognized at a point in time. The standard requires certain costs incurred to obtain a contract to be recorded as an asset when incurred and expensed as the transfer of control of the underlying performance obligations occur or over the estimated customer life, depending on the nature of the underlying contract. As a result, upon adopting ASC 606, the Company deferred previously recognized costs for contracts not completed as of the effective date. The estimated customer life has been

determined to be approximately 60 months resulting in the deferral of costs historically expensed at a point in time over this period. This change resulted in an increase to accumulated deficit of $1.5 million as of October 1, 2018.

Additional changes to the Company’s accumulated deficit were made as the result of adopting ASC 606. These changes, which resulted in a cumulative decrease to accumulated deficit of $0.2 million as of October 1, 2018, were driven by the identification of additional performance obligations as well as changes in the transfer of control of certain performance obligations across both the Brooks Semiconductor Solutions Group and Brooks Life Science segments. The additional changes to the Company’s accumulated deficit included a cumulative decrease to accumulated deficit of $0.2 million from discontinued operations.

As the Company has adopted ASC 606 using the modified retrospective method, the standard requires disclosure of impact from adoption of the standard to each financial statement line item in the current reporting period. The impact of adoption of ASC 606 on the Company’s Consolidated Statement of Operations and Consolidated Balance Sheet was as follows:



		Year Ended September 30, 2019
			Without adoption of		Effect of Change
	As Reported		ASC 606		Higher/(Lower)

Revenue	$	780,848	$	781,714	$	(866)
Cost of revenue		464,588		466,425		(1,837)
Gross profit		316,260		315,289		971
Operating expenses		270,222		269,559		663
Operating income	$	46,038	$	45,730	$	308


		September 30, 2019
			Without adoption of		Effect of Change
	As Reported		ASC 606		Higher/(Lower)
Prepaid expenses and other current assets	$	46,332	$	42,294	$	4,038
Other assets		20,506		19,686		820
Deferred revenue		29,435		27,390		2,045
Accumulated deficit		(586,412)		(589,225)		2,813

The difference between the reported results and the results without the adoption of ASC 606 was primarily driven from the elimination of revenue constraints due to billing limitations that resulted in acceleration of revenue within the Brooks Semiconductor Solutions Group segment and the deferral of fees associated with the registration of biological samples within the Brooks Life Science segment. Amortization of costs to obtain a contract capitalized through the cumulative effect adjustment described above have resulted in additional expense in the current period under ASC 606. Except as disclosed above, the adoption of ASC 606 did not have a significant impact on the Company’s Consolidated Statement of Operations for the year ended September 30, 2019 and Consolidated Balance Sheet as of September 30, 2019.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business. ASU 2017- 01 clarifies the definition of a business with the objective of addressing whether transactions involving in-substance nonfinancial assets, held directly or in a subsidiary, should be accounted for as acquisitions or disposals of nonfinancial assets or of businesses. The Company adopted this standard effective October 1, 2018. The adoption of ASU 2017-01 did not have a material impact on the Company’s Consolidated Financial Statements.

In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections. The ASU clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the U.S. Securities and Exchange Commission’s regulations, thereby eliminating redundancies and making the codification easier to apply.

This ASU is effective upon issuance and did not have a material impact on the Company’s Consolidated Financial Statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statements of cash flows. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted the new standard effective July 1, 2019 since the Company booked the restricted cash in connection with closing of the Disposition on the same date. The adoption of ASU 2016-18 did not have a material impact on the Company’s Consolidated Financial Statements.
