Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation – The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and subsidiaries in which it has a controlling interest. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. The equity method of accounting is used for investments over which the Company has a significant influence but not a controlling financial interest. All material intercompany accounts and transactions have been eliminated in consolidation.

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.

Change in Accounting Estimate

Change in Accounting Estimate - The Company regularly reviews inventory quantities and inventory purchase commitments and writes down excess and obsolete inventory to its net realizable value, and records a loss for expected purchase order cancellation charges and for excess inventory purchase commitments that cannot be cancelled. The write-down is primarily based on historical inventory usage adjusted for expected changes in product demand and production requirements.

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.

Cash Equivalents

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 of $0.6 million and $2.4 million as of September 30, 2015 and 2014, respectively, includes collateral for bank guarantees required by certain customers from whom deposits have been received in advance of shipment. Restricted cash as of September 30, 2015 includes $0.2 million relating the Company's proportional responsibility, assumed in connection with the BTU acquisition, for clean-up costs at a Superfund site. Restricted cash of September 30, 2014 includes cash received from research and development grants related to our ion implant technology to be used for research and development projects.

Accounts receivable and allowance for doubtful accounts

Accounts Receivable and Allowance for Doubtful Accounts – Accounts receivable are recorded at the gross 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.

Concentrations of Credit Risk

Concentrations of Credit Risk – Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and trade accounts receivable. The Company’s customers consist of solar cell and semiconductor manufacturers worldwide, as well as the lapping and polishing marketplace. 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. Reserves for potentially uncollectible receivables are maintained based on an assessment of collectability.

The Company maintains its cash, cash equivalents and restricted cash in multiple financial institutions. Balances in the United States (approximately 62% of total cash balances) are primarily invested in US Treasuries or are in financial institutions insured by the Federal Deposit Insurance Corporation (FDIC). The remainder of the Company’s cash is maintained with financial institutions with reputable credit in The Netherlands, France and China.

Inventories

Inventories – We value our inventory at the lower of cost or net realizable value. Costs for approximately 60% of inventory are determined on an average cost basis with the remainder determined on a first-in, first-out (FIFO) basis.

Notes and Other Receivables

Notes and Other Receivables - Notes and other Receivable consists amounts due the Company for the sale of Kingstone shares and repayment of a loan (see Note 15 "Deconsolidation"). The carrying amount of the notes receivable approximates fair value due to the short-term nature of the notes.

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.

Goodwill

Goodwill - 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.

Intangibles

Intangibles - Intangible assets are capitalized and amortized on a straight-line basis over their useful life if the life is determinable. If the life is not determinable, amortization is not recorded.

Warranty

Warranty – A limited warranty is provided free of charge, generally for periods of 12 to 24 months to all purchasers of the Company’s new products and systems. Accruals are recorded for estimated warranty costs at the time revenue is recognized.

Research and development expense

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 and development expenses.

Shipping expenses

Shipping Expense – Shipping expenses of $2.5 million, $1.0 million and $0.8 million for fiscal 2015, 2014 and 2013 are included in selling, general and administrative expenses.

Foreign Currency Transactions and Translation

Foreign Currency Transactions and Translation – The functional currency of the Company’s European operations is the Euro.

Income Taxes

Income Taxes - The Company files 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. The Netherlands operations file separate returns in that country. The Company computes deferred income tax assets and liabilities based upon cumulative temporary differences between financial reporting and taxable income, carryforwards available and enacted tax laws. The Company also accrues 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.

Stock-Based Compensation

Stock-Based Compensation - The Company measures 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. 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.

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), the Company groups its 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 the Company's policy to use observable inputs whenever reasonably practicable in order to minimize the use of unobservable inputs when developing fair value measurements. When available, the Company uses 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, the Company is 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 in the Condensed 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 3 in the fair value hierarchy.

Pensions

Pensions—The Company has retirement plans covering substantially all employees. The principal plans are the multiemployer defined benefit pension plans of the Company’s operations in the Netherlands and France and the multiemployer plan for hourly union employees in Pennsylvania and the Company's defined contribution plan that covers substantially all of the employees in the United States. The multiemployer plans in the United States and France are insignificant.

New Accounting Pronouncements

Impact of Recently Issued Accounting Pronouncements

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in ASU No. 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The recognition and measurement guidance for debt issuance costs are not affected by the amendments. ASU No. 2015-03 must be applied retrospectively and is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. In August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. ASU No. 2015-15 states that for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting such costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The adoption of the new guidance is not expected to materially impact the Company’s consolidated financial position or results of operations

In August 2015, the FASB issued ASC Update No. 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965). Update No. 2015-12 has three parts. Part I designates contract value as the only required measure for fully benefit-responsive investment contracts. Part II simplifies the investment disclosure requirements under Topics 820, 960, 962, and 965 for employee benefits plans and Part III provides an alternative measurement date for fiscal periods that do not coincide with a month-end date. Update No. 2015-12 is effective for fiscal years beginning after December 15, 2015. The adoption of Update No. 2015-12 is not expected to have a material impact on our financial position or results of operations.

In July 2015, the FASB issued Accounting Standards Update ("ASU") No. 2015-11, Simplifying the Measurement of Inventory. This ASU simplifies the measurement of inventory by requiring certain inventory to be measured at the lower of cost or net realizable value. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016 and for interim periods therein. We do not expect adoption of this ASU to have a material impact on our consolidated financial position and results of operations.

In June 2015, the FASB issued ASU 2015-10, Technical Corrections and Improvements , which clarifies various topics in the FASB Accounting Standards Codification. ASU 2015-10 is effective for the interim and annual periods ending after December 15, 2015. Early adoption is permitted. We are currently assessing the impact of this ASU, but do not expect it to have a material impact on our consolidated financial position and results of operations.

In May 2015, the FASB issued ASU 2015-08, Business Combinations (Topic 805): Pushdown Accounting - Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115, or ASU 2015-08. The amendments in ASU 2015-08 amend various SEC paragraphs included in the FASB’s Accounting Standards Codification to reflect the issuance of Staff Accounting Bulletin No. 115, or SAB 115. SAB 115 rescinds portions of the interpretive guidance included in the SEC’s Staff Accounting Bulletins series and brings existing guidance into conformity with ASU No. 2014-17, Business Combinations (Topic 805): Pushdown Accounting, which provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. We have adopted the amendments in ASU 2015-08, effective May 8, 2015, as the amendments in the update are effective upon issuance. The adoption did not have a material impact on our consolidated financial position and results of operation.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40). This ASU provides guidance that will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, including whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then this ASU requires the customer to account for the software license consistent with the acquisition of other software licenses; otherwise, the customer should account for the arrangement as a service contract. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Entities can elect to adopt the amendments either prospectively to all arrangements entered into after the effective date or retrospectively to all prior periods. We are currently assessing the impact of this ASU.

In April 2015, the FASB issued ASU No. 2015-3, Interest-Imputation of Interest (Subtopic 835-30). This ASU requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. The ASU requires retrospective application and represents a change in accounting principle. The ASU is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. We are currently assessing the impact of this ASU.

In January 2015, the FASB issued ASU No. 2015-1, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20). The FASB is issuing this ASU as part of its initiative to reduce costs and complexity in accounting standards, known as its Simplification Initiative. This ASU eliminates from generally accepted accounting principles in the United States (" GAAP") the concept of extraordinary items in an effort to save time and reduce costs, while alleviating uncertainty and maintaining accurate and fulsome disclosure. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. We are currently assessing the impact of this ASU but do not expect it to have a material impact on our consolidated financial position and results of operations.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes most of the current revenue recognition requirements. The core principle of the new 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 these goods or services. New disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. This guidance is effective for the Company in the first quarter of fiscal year 2018 and early application is not permitted. Entities must adopt the new guidance using one of two retrospective application methods. The Company is currently evaluating the the standard and the impact on our financial position and results of operations.
