Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation – The consolidated financial statements include the accounts of the Company and our wholly-owned subsidiaries and subsidiaries in which we have a controlling interest. We report non-controlling interests in consolidated entities as a component of equity separate from our equity. The equity method of accounting is used for investments over which we have a significant influence but not a controlling financial interest. All material intercompany accounts and transactions have been eliminated in consolidation. Effective July 1, 2017, we purchased the non-controlling interest in SoLayTec, pursuant to which SoLayTec became a wholly-owned subsidiary of Amtech. Beginning July 1, 2017, the non-controlling interest will no longer be reported. Prior amounts have not been restated.

Use of Estimates

Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents – We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Our cash and cash equivalents consist of amounts invested in U.S. money market funds and various U.S. and foreign bank operating and time deposit accounts.

Restricted Cash

Restricted Cash – Restricted cash includes collateral for bank guarantees required by certain customers from whom deposits have been received in advance of shipment.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts – Accounts receivable are recorded at the sales price of products sold to customers on trade credit terms. Accounts receivable are considered past due when payment has not been received from the customer within the normal credit terms extended to that customer. A valuation allowance is established for accounts when collection is no longer probable. Accounts are written off against the allowance when the probability of collection is remote.

Accounts Receivable - Unbilled and Other

Accounts Receivable – Unbilled and Other – Unbilled and other accounts receivable consist mainly of the contingent portion of the sales price that is not collectible until successful installation of the product. These amounts are generally billed upon final customer acceptance.

Inventory

Inventory – We value our inventory at the lower of cost or net realizable value. Costs for approximately 55% and 50% of inventory as of September 30, 2017 and 2016, respectively, are determined on an average cost basis with the remainder determined on a first-in, first-out (FIFO) basis.

Property, Plant and Equipment

Property, Plant and Equipment – Property plant, and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred. The cost of property retired or sold and the related accumulated depreciation and amortization are removed from the applicable accounts when disposition occurs and any gain or loss is recognized. Depreciation and amortization is computed using the straight-line method over the estimated useful life of the asset. Useful lives for equipment, machinery and leasehold improvements range from three to seven years; for furniture and fixtures from five to ten years; and for buildings from 20 to 30 years.

Reviews are regularly performed to determine whether facts and circumstances exist which indicate that the useful life is shorter than originally estimated or the carrying amount of assets may not be recoverable. When an indication exists that the carrying amount of long-lived assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets.

Intangible Assets

Intangible Assets – Intangible assets are capitalized and amortized on a straight-line basis over their estimated useful life, if the life is determinable. If the life is not determinable, amortization is not recorded. We regularly perform reviews to determine if facts and circumstances exist which indicate that the useful lives of our intangible assets are shorter than originally estimated or the carrying amount of these assets may not be recoverable. When an indication exists that the carrying amount of intangible assets may not be recoverable, we assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Such impairment test is based on the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Impairment, if any, is based on the excess of the carrying amount over the estimated fair value of those assets.

Goodwill

Goodwill - Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill and intangible assets with indefinite lives are not subject to amortization, but are tested for impairment when it is determined that it is more likely than not that the fair value of a reporting unit or the indefinite-lived intangible asset is less than its carrying amount, typically at the end of the fiscal year, or more frequently if circumstances dictate. If it is concluded that there is a potential impairment, we would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value (although the loss would not exceed the total amount of goodwill allocated to the reporting unit). Impairment tests include the use of estimates and assumptions that are inherently uncertain. Changes in these estimates and assumptions could materially affect the determination of fair value or goodwill impairment, or both.

Revenue Recognition

Revenue Recognition – We review product and service sales contracts with multiple deliverables to determine if separate units of accounting are present. Where separate units of accounting exist, revenue allocated to delivered items is the lower of the relative selling price of the delivered items in the sales arrangement or the portion of the selling price that is not contingent upon performance of the service.

We recognize revenue when persuasive evidence of an arrangement exists; the product has been delivered and title has transferred, or services have been rendered; and the seller’s price to the buyer is fixed or determinable and collectability is reasonably assured. For us, this policy generally results in revenue recognition at the following points:

For our equipment business, transactions where legal title passes to the customer upon shipment, we recognize revenue upon shipment for those products where the customer’s defined specifications have been met with at least two similarly configured systems and processes for a comparably situated customer. Our selling prices may include both equipment and services, i.e., installation and start-up services performed by our service technicians. The equipment and services are multiple deliverables. Certain equipment that has a positive track record of successful installation and customer acceptance are considered to be routine systems. Our recognition of revenue upon delivery of such equipment that has been routinely installed and accepted is equal to the total selling price minus the relative selling price of the undelivered services.

Where the installation and acceptance of more than two similarly configured items of equipment have not become routine, recognition of revenue upon delivery of equipment is limited to the lesser of (i) the total selling price minus the relative selling price of the undelivered services or (ii) the non-contingent amount. Since we defer only those costs directly related to installation, or other unit of accounting not yet delivered, and the portion of the contract price is often considerably greater than the relative selling price of those items, our policy at times will result in deferral of profit that is disproportionate in relation to the deferred revenue. When this is the case, the gross margin recognized in one period will be lower and the gross margin reported in a subsequent period will improve.

For products where the customer’s defined specifications have not been met with at least two similarly configured systems and processes, the revenue and directly related costs are deferred at the time of shipment and later recognized at the time of customer acceptance or when this criterion has been met. We have, on occasion, experienced longer than expected delays in receiving cash from certain customers pending final installation or system acceptance. If some of our customers refuse to pay the final payment, or otherwise delay final acceptance or installation, the deferred revenue would not be recognized, adversely affecting our future cash flows and operating results.


3.	Sales of certain equipment, spare parts and consumables are recognized upon shipment, as there are no post shipment obligations other than standard warranties.


4.	Service revenue is recognized upon performance of the services requested by the customer. Revenue related to service contracts is recognized ratably over the period of the contract or in accordance with the terms of the contract, which generally coincides with the performance of the services requested by the customer.

Deferred Profit

Deferred Profit – Revenue deferred pursuant to our revenue policy, net of the related deferred costs, if any, is recorded as deferred profit in current liabilities.

Warranty

Warranty – A limited warranty is provided free of charge, generally for periods of 12 to 24 months to all purchasers of our new products and systems. Accruals are recorded for estimated warranty costs at the time revenue is recognized, generally upon shipment or acceptance, as determined under the revenue recognition policy above. On occasion, we have been required and may be required in the future to provide additional warranty coverage to ensure that the systems are ultimately accepted or to maintain customer goodwill. While our warranty costs have historically been within our expectations and we believe that the amounts accrued for warranty expenditures are sufficient for all systems sold through September 30, 2017, we cannot guarantee that we will continue to experience a similar level of predictability with regard to warranty costs. In addition, technological changes or previously unknown defects in raw materials or components may result in more extensive and frequent warranty service than anticipated, which could result in an increase in our warranty expense.

Shipping Expense

Shipping Expense – Shipping expenses of $1.9 million, $2.3 million and $2.5 million for 2017, 2016 and 2015 are included in selling, general and administrative expenses.

Advertising Expense

Advertising Expense – Advertising costs are expensed as incurred. Advertising expense of $0.4 million, $0.6 million and $0.5 million for 2017, 2016 and 2015 are included in selling, general and administrative expenses.

Stock-Based Compensation

Stock-Based Compensation – We measure compensation costs relating to share-based payment transactions based upon the grant-date fair value of the award. Those costs are recognized as expense over the requisite service period, which is generally the vesting period, less an estimate of expected forfeitures. Forfeitures were estimated based upon historical experience. Beginning in 2018, we will begin recognizing forfeitures as they occur. The benefits or deficiencies of tax deductions in excess of or less than recognized compensation cost are reported as cash flow from financing activities rather than as cash flow from operating activities.

We estimate the fair value of stock option awards on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes model requires us to apply highly subjective assumptions, including expected stock price volatility, expected life of the option and the risk-free interest rate. A change in one or more of the assumptions used in the model may result in a material change to the estimated fair value of the stock-based compensation.

Research, Development and Engineering Expenses

Research, Development and Engineering Expenses – Research, development and engineering expenses consist of the cost of employees, consultants and contractors who design, engineer and develop new products and processes as well as materials, supplies and facilities used in producing prototypes. Payments received for research and development grants prior to the meeting of milestones are recorded as unearned research and development grant liabilities and included in other accrued liabilities on the balance sheet. When certain contract requirements are met, governmental research and development grants are netted against research, development and engineering expenses.

Foreign Currency Transactions and Translation

Foreign Currency Transactions and Translation – We use the U.S. dollar as our reporting currency. Our operations in Europe, China and other countries are primarily conducted in their functional currencies, the Euro, Renminbi, or the local country currency, respectively. Accordingly, assets and liabilities of the subsidiaries are translated into U.S. dollars at the exchange rate in effect at the balance sheet dates. Income and expense items are translated at the average exchange rate for each month within the year. The resulting translation adjustments are recorded directly in accumulated other comprehensive income (loss), net of tax - foreign currency translation adjustments as a separate component of stockholders’ equity. Net foreign currency transaction gains/losses, including transaction gains/losses on intercompany balances that are not of a long-term investment nature and non-functional currency cash balances, are reported as a separate component of non-operating (income) expense in our consolidated statements of operations.

Income Taxes

Income Taxes – We file consolidated federal income tax returns in the United States for all subsidiaries except those in the Netherlands, France, Hong Kong and China, where separate returns are filed. We compute deferred income tax assets and liabilities based upon cumulative temporary differences between financial reporting and taxable income, carryforwards available and enacted tax laws. We also accrue a liability for uncertain tax positions when it is more likely than not that such tax will be incurred.

Deferred tax assets reflect the tax effects of temporary differences between the carrying value of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management and based on the weight of available evidence, it is more likely than not that a portion or all of the deferred tax asset will not be realized. Each quarter, the valuation allowance is re-evaluated.

Concentrations of Credit Risk

Concentrations of Credit Risk – Our customers consist of solar cell and semiconductor manufacturers worldwide, as well as the lapping and polishing marketplace. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and trade accounts receivable. Credit risk is managed by performing ongoing credit evaluations of the customers’ financial condition, by requiring significant deposits where appropriate, and by actively monitoring collections. Letters of credit are required of certain customers depending on the size of the order, type of customer or its creditworthiness, and country of domicile.

As of September 30, 2017, two customers individually represented 24% and 11% of accounts receivable. As of September 30, 2016, one customer individually represented 11% of accounts receivable.

We maintain our cash, cash equivalents and restricted cash in multiple financial institutions. Balances in the United States (approximately 45% and 70% of total cash balances as of September 30, 2017 and 2016, respectively) are primarily invested in US Treasuries or are in financial institutions insured by the Federal Deposit Insurance Corporation (FDIC). The remainder of our cash is maintained with financial institutions with reputable credit in The Netherlands, France, China, the United Kingdom, Singapore and Malaysia.

Fair Value of Financial Instruments

Fair Value of Financial Instruments – In accordance with the requirements of the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), we group our financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 – Valuation is based upon quoted market price for identical instruments traded in active markets.

Level 2 – Valuation is based on quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.

In accordance with the requirements of the Fair Value Measurements and Disclosures Topic of the FASB ASC, it is our policy to use observable inputs whenever reasonably practicable in order to minimize the use of unobservable inputs when developing fair value measurements. When available, we use quoted market prices to measure fair value. If market prices are not available, the fair value measurement is based on models that use primarily market based parameters including interest rate yield curves, option volatilities and currency rates. In certain cases, where market rate assumptions are not available, we are required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. Changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.

Cash, Cash Equivalents and Restricted Cash – Included in Cash and Cash Equivalents and Restricted Cash in the Consolidated Balance Sheets are money market funds invested in treasury bills, notes and other direct obligations of the U.S. Treasury and foreign bank operating and time deposit accounts. The fair value of this cash equivalent is based on Level 1 inputs in the fair value hierarchy.

Receivables and Payables – The recorded amounts of these financial instruments, including accounts receivable and accounts payable, approximate their fair value because of the short maturities of these instruments. If measured at fair value in the financial statements, these financial instruments would be classified as Level 2 in the fair value hierarchy.

Debt – The recorded amounts of these financial instruments, including long-term debt and current maturities of long-term debt, approximate fair value and are considered Level 2 in the fair value hierarchy.

Recently Issued Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The guidance is intended to simplify the subsequent accounting for goodwill acquired in a business combination. Prior guidance required utilizing a two-step process to review goodwill for impairment. A second step was required if there was an indication that an impairment may exist, and the second step required calculating the potential impairment by comparing the implied fair value of the reporting unit’s goodwill (as if purchase accounting were performed on the testing date) with the carrying amount of the goodwill. The new guidance eliminates the second step from the goodwill impairment test. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value (although the loss should not exceed the total amount of goodwill allocated to the reporting unit). The guidance requires prospective adoption and will be effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption of this guidance is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We early adopted this guidance in the fourth quarter of fiscal 2017 with no impact on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash.” The amendments address diversity in practice that exists in the classification and presentation of changes in restricted cash and require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This ASU is effective retrospectively for fiscal years and interim periods within those years beginning after December 15, 2017. We plan to adopt this standard effective October 1, 2018, the first quarter of our fiscal year 2019. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. The new standard applies to financial assets measured at amortized cost basis, including receivables that result from revenue transactions and held-to-maturity debt securities. The new guidance will be effective for us starting in the first quarter of fiscal 2021. Early adoption is permitted starting in the first quarter of fiscal 2020. We are in the process of determining the effects the adoption will have on our consolidated financial statements as well as whether to adopt the new guidance early.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718).” ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016 and for the interim periods therein. This new standard increases volatility in the statement of operations by requiring all excess tax benefits and deficiencies to be recognized as discrete income tax benefits or expenses in the statement of operations in the period in which they occur. We adopted the new standard as of October 1, 2017, and prospectively applied the provisions in this guidance requiring recognition of excess tax benefits and deficits in the statement of operations. Also, as a result of the adoption of the new standard, we made an accounting policy election to recognize forfeitures as they occur and no longer estimate expected forfeitures. The provisions in this guidance requiring the use of a modified retrospective transition method would have required us to record a cumulative-effect adjustment in retained earnings as of October 1, 2017. We elected not to adjust retained earnings and to record such cumulative-effect adjustment as stock-based compensation in the first quarter of 2018 on the basis of immateriality. Lastly, we applied the provisions of this guidance relating to classification on the statement of cash flows retrospectively.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use-assets. ASU 2016-02 also requires improved disclosures to help users of financial statements better understand the amount, timing and uncertainty of cash flows arising from leases. This ASU is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We will adopt the standard as of October 1, 2019, the start of our fiscal 2020. We are currently in the process of evaluating the impact of this standard on our consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes.” This ASU requires entities to classify deferred tax liabilities and assets as noncurrent in a classified statement of financial position. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. We will adopt this standard effective October 1, 2017, the first quarter of our fiscal 2018. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which amends the existing accounting standards for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to amend ASU 2014-09 by approving a one-year deferral of the mandatory effective date as well as providing the option to early adopt the standard on the original effective date. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We are in the process of determining the effect that the adoption will have on our consolidated financial statements. Based on our analysis to date, we have reached the following tentative conclusions regarding the new standard and how we expect it to affect our consolidated financial statements and related disclosures:


•	We expect to adopt the standard as of October 1, 2018, the start of our first quarter of fiscal 2019.


•	We expect to use the cumulative effect transition method. Such method provides that upon applying the new standard, the cumulative effect from prior periods is recognized in our consolidated balance sheet as of the date of adoption, including an adjustment to retained earnings. Prior periods will not be retrospectively adjusted.


•	We believe that since substantially all of our revenue is contractual, substantially all of our revenue falls within the scope of ASU 2014-09, as amended.

•

As discussed above, our equipment revenue is generally recognized upon shipment, except for non-routine technology equipment, which is subject to a deferral until acceptance. We are continuing to evaluate how the new standard will affect the allocation of the contract prices between equipment and service deliverables and the timing of the recognition of such revenue, as well as how this will apply to our non-routine technology equipment. Additionally, we are reviewing the effect of customer acceptance clauses on the timing of revenue recognition and related deferrals, for both routine and non-routine technology equipment, under the new standard.

•

We believe that the only significant incremental costs incurred to obtain contracts with our clients within the scope of ASU 2014-09, as amended, are sales commissions. Under current accounting standards, we recognize sales commissions as the revenue is earned and record such amounts within selling and administrative expenses in our statements of operations. The majority of our contracts are completed within a one-year performance period. Under the new standard, we expect to record sales commissions on contracts with performance periods that exceed one year as an asset and amortize the asset to expense over the related contract performance period in proportion to the revenue recognized.


•	We expect that our disclosures in our notes to our consolidated financial statements related to revenue recognition will be significantly expanded under the new standard.

Our analysis and evaluation of the new standard will continue through its effective date in the first quarter of fiscal 2019. A substantial amount of work remains to be completed due to the complexity of the new standard, the application of judgment and the requirement for the use of estimates in applying the new standard, as well as the volume of our client portfolio and the related terms and conditions of our contracts that must be reviewed. The quantification of the effects of the new standard, including the items discussed above, is a significant undertaking. Further, we will be required to implement necessary changes in our processes, accounting systems and internal controls in conjunction with applying the new standard.
