NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THREE AND SIX MONTHS ENDED ~~DECEMBER~~MARCH 31, ~~2016~~2017 AND ~~2015~~2016

(UNAUDITED)


1.	Summary of Significant Accounting Policies

Nature of Operations and Basis of Presentation - Amtech Systems, Inc. (the “Company”, “Amtech”, “we”, “us” or “our”) is a global manufacturer of capital equipment, atomic layer deposition (“ALD”) including thermal processing, silicon wafer handling automation, and related consumables used in fabricating solar cells, LED and semiconductor devices. ~~The Company sells~~We sell these products to solar cell and semiconductor manufacturers worldwide, particularly in Asia, the United States and Europe.

~~The Company serves~~We serve niche markets in industries that are experiencing rapid technological advances and which historically have been very cyclical. Therefore, future profitability and growth depend on ~~the Company’s~~our ability to develop or acquire and market profitable new products and on ~~its~~our ability to adapt to cyclical trends.

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), and consequently do not include all disclosures normally required by accounting principles generally accepted in the United States of America. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments necessary, all of which are of a normal and recurring nature, to present fairly our financial position, results of operations and cash flows. Certain information and note disclosures normally included in financial statements have been condensed or omitted pursuant to the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K, as amended, for the fiscal year ended September 30, 2016.

The consolidated results of operations for the three and six months ended ~~December~~March 31, ~~2016,~~2017, are not necessarily indicative of the results to be expected for the full fiscal year.

Principles of Consolidation – The consolidated financial statements include the accounts of the Company and its ~~wholly owned~~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 -– 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.

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 the ~~Company's~~Company’s equipment business, transactions where legal title passes to the customer upon shipment, revenue is recognized 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. 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. Revenue recognition 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 there have been installation and acceptance of more than two similarly configured items of equipment, but installation and acceptance 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~~another 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. On occasion, ~~the Company has~~we have experienced longer than expected delays in receiving cash from certain customers pending final installation or system acceptance. If some customers refuse to pay the final payment, or otherwise delay final acceptance or installation, the deferred revenue would not be recognized, adversely affecting 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 – Revenue deferred pursuant to ~~the Company’s~~our revenue recognition policy, net of the related deferred costs, if any, is recorded as deferred profit in current liabilities. The components of deferred profit are as follows:


	December 31, 2016		September 30, 2016		March 31, 2017		September 30, 2016
	(dollars in thousands)				(dollars in thousands)
Deferred revenues	$	8,164	$	7,029	$	9,462	$	7,029
Deferred costs	4,352		2,320		4,453		2,320
Deferred profit	$	3,812	$	4,709	$	5,009	$	4,709

Cash Equivalents – ~~The Company considers~~– We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. 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 of ~~$3.3~~$2.6 million and $0.9 million as of ~~December~~March 31, ~~2016~~2017, and September 30, 2016, respectively, includes collateral for bank guarantees required by certain customers from whom deposits have been received in advance of shipment. Restricted cash as of ~~December~~March 31, ~~2016~~2017 and September 30, 2016 includes $0.2 million relating ~~the Company's~~our proportional responsibility, assumed in connection with the BTU International Inc. (“BTU”) acquisition, for clean-up costs at a Superfund site. Refer to Note 8 to Condensed Consolidated Financial Statements, Commitments and Contingencies, for more detail regarding our proportional liability related to the Superfund site.

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 – Unbilled and other accounts receivable consist mainly of a 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. Accounts receivable also includes Value-added tax ~~(“VAT”)~~ receivable.

Concentrations of Credit Risk – Financial instruments that potentially subject ~~the Company~~us to significant concentrations of credit risk consist principally of cash and trade accounts receivable. ~~The Company’s~~Our 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 our customers’ financial condition, by requiring significant deposits where appropriate, and by actively monitoring collections.

~~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~~We maintain our cash, cash equivalents and restricted cash in multiple financial institutions. ~~Approximately 65%~~As of ~~the Company's~~March 31, 2017, approximately 46% of our total cash balances are primarily invested in USU.S. Treasuries or are in financial institutions insured by the Federal Deposit Insurance Corporation ~~(FDIC)~~(“FDIC”). The remainder of ~~the Company’s~~our cash is maintained with financial institutions with reputable credit ratings in The Netherlands, France and China.

As of ~~December~~March 31, ~~2016, one customer~~2017, two customers individually represented ~~12%~~13% and 11% of accounts receivable. As of September 30, 2016, one customer individually represented 11% of accounts receivable.

Refer to Note 6 to Condensed Consolidated Financial Statements, Major Customers and Foreign Sales, for information regarding revenue ~~and assets~~ in other countries subject to fluctuation in foreign currency exchange rates.

Inventories – We value our inventory at the lower of cost or net realizable value. Costs for approximately 50% of inventory is valued on an average cost basis with the remainder determined on a first-in, first-out (FIFO) basis. The components of inventories are as follows:

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 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. 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 ~~20-30~~20 to 30 years.

The following is a summary of property, plant and equipment:

Long-lived assets – Long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Warranty – A limited warranty is provided free of charge, generally for periods of 12 to 24 months, for all purchases of ~~the Company’s~~our new products and systems. Accruals are recorded for estimated warranty costs at the time revenue is recognized. Estimates are based on past experience and take into account the nature of the products under warranty. The following is a summary of activity in accrued warranty expense:

Stock-Based Compensation -– ~~The Company measures~~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. The benefits of tax deductions in excess of recognized compensation cost are credited to additional paid-in capital and reported as cash flow from financing activities.

Stock-based compensation expense reduced ~~the Company’s~~our results of operations by the following amounts:

(1)	Stock-based compensation expense is included in selling, general and administrative expenses.

Stock options issued under the terms of ~~the Company's~~our option plans have, or will have, an exercise price equal to the fair market value of the common stock at the close of trading on the NASDAQ the trading day prior to the date of the option grant and expire no later than 10 years from the date of grant, with the most recent option grant expiring in ~~2026.~~2027. Options issued by ~~the Company~~us generally vest over six months to four years, subject to ~~the Company's~~our board of ~~directors'~~directors’ (the “Board”) discretion pursuant to ~~the Company's~~our share-based compensation plans.

Stock option transactions and the options outstanding are summarized as follows:

Weighted average fair value of options granted during the period	$	2.88				$	3.03				$	3.04				$	3.04

The fair value of options was estimated at the applicable grant date using the Black-Scholes option pricing model with the following assumptions:


	Three Months Ended December 31,		Six Months Ended March 31,
	2016	2015	2017	2016
Risk free interest rate	2%	2%	2%	2%
Expected life	6 years	6 years	6 years	6 years
Dividend rate	0%	0%	0%	0%
Volatility	62%	62%	63%	63%

To estimate expected lives for this valuation, it was assumed that options will be exercised at varying schedules after becoming fully vested. Forfeitures have been estimated at the time of grant and will be revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based upon historical experience. Fair value computations are highly sensitive to the volatility factor assumed; the greater the volatility, the higher the computed fair value of the options granted. ~~The Company uses~~We use historical stock prices to determine the volatility factor.

~~The Company awards~~We award restricted shares under ~~its~~our existing share-based compensation plans. ~~The Company's~~Our restricted share awards vest in equal annual installments over a two to four year period. The total value of these awards is expensed on a ratable basis over the service period of the employees receiving the grants. The “service period” is the time during which the employees receiving grants must remain employees for the shares granted to fully vest.

Restricted stock transactions and awards outstanding are summarized as follows:

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”~~(the “FASB”) Accounting Standards Codification (“ASC”), ~~the Company groups its~~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 upon 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~~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, ~~the Company uses~~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, ~~the Company is~~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 in the Condensed Consolidated Balance Sheets are money market funds invested in treasury bills, notes and other direct obligations of the U.S. Treasury or are in financial institutions insured by the ~~Federal Deposit Insurance Corporation (FDIC)~~FDIC 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.

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.

Pensions – ~~The Company has~~We have retirement plans covering substantially all employees. The principal plans are the multiemployer defined benefit pension plans of ~~the Company’s~~our operations in The Netherlands and France and the plan for hourly union employees in Pennsylvania. The multiemployer plans in the United States and France are insignificant to ~~the Company's~~our results of operations and financial condition. ~~The Company's~~Our defined contribution plans cover substantially all of the employees in the United States. ~~The Company matches~~We match certain employee funds on a discretionary basis while certain subsidiaries require a minimum match to maintain their safe harbor status.

Shipping ~~expense~~Expense – Shipping expenses of ~~$0.4~~$0.5 million and $0.3 million for ~~each of~~ the three months ended ~~December~~March 31, 2017 and 2016, respectively, are included in selling, general and ~~2015,~~administrative expenses. Shipping expenses of $0.9 million and $0.8 million for the six months ended March 31, 2017 and 2016, respectively, are included in selling, general and administrative expenses.

Research, ~~development~~Development and ~~engineering expense~~Engineering Expense – Research, development and engineering expenses consist of the cost of employees, consultants and contractors who design, engineer and develop new products and processes; materials and supplies used in those activities; and product prototyping. ~~The Company receives~~We receive reimbursements through governmental research and development grants which are netted against these expenses when certain conditions have been met. The table below shows gross research and development expenses and grants earned:

Impact of Recently Issued Accounting Pronouncements

In ~~November 2016,~~March 2017, the FASB issued Accounting Standards Update ~~("ASU"~~(“ASU”) No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented outside of any subtotal of operating income. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted. We are currently in the process of evaluating the impact of the adoption on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”. 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 plan to early adopt this guidance in the fourth quarter of fiscal 2017, or with any interim impairment tests during fiscal 2017, and do not expect it to have a significant impact on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, ~~Statement~~“Statement of Cash Flows: Restricted ~~Cash~~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. ~~The Company does~~We do not expect the adoption of this ASU to have a material impact on ~~its~~our consolidated financial statements.

In October 2016, the FASB issued ASU ~~No.~~ 2016-16, ~~Income~~“Income Taxes: Intra-Entity Transfers of Assets Other than ~~Inventory~~Inventory”. The amendments in this ASU remove the prohibition against the recognition of current and deferred income tax effects of intra-entity transfers of assets other than inventory until the asset has been sold to an outside party. The ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2017. ~~The Company does~~We do not expect the adoption of this ASU to have a material impact on ~~its~~our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. These amendments provide cash flow statement classification guidance for: 1. Debt Prepayment or Debt

Extinguishment Costs; 2. Settlement of Zero-Coupon Debt Instruments or Other Debt Instruments with Coupon Interest Rates That Are Insignificant in Relation to the Effective Interest Rate of the Borrowing; 3. Contingent Consideration Payments Made after a Business Combination; 4. Proceeds from the Settlement of Insurance Claims; 5. Proceeds from the Settlement of Corporate-Owned Life Insurance Policies, including Bank-Owned Life Insurance Policies; 6. Distributions Received from Equity Method Investees; 7. Beneficial Interests in Securitization Transactions; and 8. Separately Identifiable Cash Flows and Application of the Predominance Principle. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early application is permitted, including adoption in an interim period. ~~The Company is~~We are currently in the process of evaluating the impact of the adoption on ~~its~~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 ~~the Company~~us starting in the first quarter of fiscal 2021. Early adoption is permitted starting in the first quarter of fiscal 2020. ~~The Company is~~We are in the process of determining the effects the adoption will have on ~~its~~our consolidated financial statements as well as whether to adopt the new guidance early.

In May 2014, the FASB issued ASU No. 2014-09 regarding ASC Topic 606, “Revenue from Contracts with ~~Customers.”~~Customers”. ASU 2014-09 provides principles for recognizing 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 August 2015, the FASB issued ASU 2015-14 to defer the effective date by one year with early adoption permitted as of the original effective date. ASU 2014-09 will be effective for Amtech’s fiscal year beginning October 1, 2018 unless we elect the earlier date of October 1, 2017. In addition, the FASB issued ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 in March 2016, April 2016, May 2016 and December 2016, respectively, to help provide interpretive clarifications on the new guidance in ASC Topic 606. ~~The Company is~~We have determined that we will not early adopt the standard and are currently assessing the impact that adopting this new accounting standard will have on ~~its~~our consolidated financial statements.

In March 2016, the FASB issued ASU ~~No.~~ 2016-09, ~~Compensation~~“Compensation - ~~“Stock~~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. ~~The Company is~~We are currently assessing the impact that adopting this new accounting standard will have on ~~its~~our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-07, “Equity Method and Joint Ventures” affecting all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership or degree of influence. ASU 2016-07 is effective for the Company beginning on ~~January 1, 2017, early adoption is permitted. The adoption of this guidance by the Company is not expected to have a material impact on its consolidated financial statements.~~

In February 2016, the FASB issued ASU ~~No.~~ 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 application is permitted. ~~The Company is~~We are currently in the process of evaluating the impact of this standard on ~~its~~our consolidated financial statements.

In January 2016, the FASB issued ASU ~~No.~~ 2016-01, “Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities”, which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017 and early adoption is not permitted. ~~The Company is~~We are currently evaluating the impact that the standard will have on ~~its~~our consolidated financial statements.

In November 2015, the FASB issued ASU ~~No.~~ 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. The adoption of this guidance ~~by the Company~~ is not expected to have a material impact on ~~its~~our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments”, which simplifies the accounting for measurement-period adjustments to provisional amounts recognized in a business combination. ASU 2015-16 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. The provisions of ASU 2015-16 are not expected to have a material effect on the Company's financial condition, results of operations, or cash flows.

~~In July 2015, the FASB issued 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. ~~The Company does~~We do not expect adoption of this ASU to have a material impact on ~~the Company's~~our consolidated financial position and results of operations.


2.	Income Taxes

The quarterly income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which ~~the Company operates.~~we operate. However, losses in certain jurisdictions and discrete items are treated separately.

Deferred tax assets and liabilities 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. ~~The Company records~~We record a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Our expectations regarding realization of our deferred tax assets is based upon the weight of all available evidence, including such factors as our recent earnings history, expected future taxable income and available tax planning strategies. ~~The Company maintains~~We maintain a valuation allowance with respect to certain state, federal and foreign deferred tax assets that may not be recovered. We have established valuation allowances on substantially all net deferred tax assets, after considering all of the available objective evidence, both positive and negative, historical and prospective, with greater weight given to historical evidence, and determined it is not more likely than not that these assets will be ~~realized~~realized.

~~The Company classifies~~We classify all of our uncertain tax positions as ~~non-current~~ income taxes ~~payable.~~payable long-term. At ~~December~~March 31, ~~2016~~2017 and September 30, 2016, the total amount of unrecognized tax benefits was approximately $3.9 million. If recognized, these amounts would favorably impact the effective tax rate. Income taxes payable long-term primarily includes, among other items, withholding taxes that are not due until the related intercompany service fees are paid.

~~The Company classifies~~We classify interest and penalties related to unrecognized tax benefits as income tax expense. As of ~~December~~March 31, ~~2016~~2017 and September 30, 2016, ~~the Company~~we had an accrual for potential interest and penalties of approximately ~~$2.4~~$2.5 million and $2.3 million, respectively, classified with ~~non-current~~ income taxes ~~payable.~~payable long-term.

~~The Company~~We and one or more of ~~its~~our subsidiaries file income tax returns in The Netherlands, France, China, Singapore, Malaysia, Hong Kong, and Germany, as well as in the U.S. and various states in the U.S. The Company and its subsidiaries have a number of open tax years dictated by statute in each of their respective taxing jurisdictions, but generally it is from 3 to 5 years in the jurisdictions in which ~~the Company files~~we file tax returns.


3.	Earnings Per Share

Basic earnings per share ~~("EPS"~~(“EPS”) is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted EPS is computed similarly to basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares had been issued. In the case of a net loss, diluted earnings per share is calculated in the same manner as basic EPS.

For the three and six months ended ~~December~~March 31, ~~2016~~2017, options for ~~1,886,000~~1,669,000 and 1,696,000 shares, respectively, are excluded from the diluted EPS calculations because they are anti-dilutive. For the three and six months ended ~~December~~March 31, ~~2015~~2016, options for ~~1,938,000~~1,906,000 shares were excluded from the diluted EPS calculations because they were anti-dilutive. These shares could be dilutive in the future.

The following table outlines basic and diluted EPS:

4. ~~Stockholders'~~Stockholders’ Equity

Shareholder Rights Plan – On December 15, 2008, ~~the Company~~Amtech and Computershare Trust Company, N.A., as Rights Agent (the “Rights Agent”), entered into an Amended and Restated Rights Agreement (the “Restated Rights Agreement”) which amended and restated the terms governing the previously authorized shareholder rights (each a “Right”) to purchase fractional shares of ~~the Company’s~~our Series A Participating Preferred Stock (“Series A Preferred”) currently attached to each of ~~the Company’s~~our outstanding Common Shares, par value $0.01 per share (“Common Shares”). As amended, each Right entitles the registered holder to purchase from ~~the Company~~us one one-thousandth of a share of Series A Preferred at an exercise price of $51.60 (the “Exercise Price”), subject to adjustment. The Rights will expire 10 years after issuance and will be exercisable if (a) a person or group becomes the beneficial owner of 15% or more of the Company’s common stock or (b) a person or group commences a tender or exchange offer that would result in the offeror beneficially owning 15% or more of ~~the Company’s~~our common stock. The Final Expiration Date (as defined in the Restated Rights Agreement) is December 14, 2018.

On October 1, 2015, ~~the Company~~we entered into a Second Amended and Restated Rights Agreement (the “Second Restated Rights Agreement”) with the Rights Agent, which expands the definition of Exempted Person to include any person that the Board, in its sole and absolute discretion, exempts from becoming an Acquiring Person under the Second Restated Rights Agreement. A Person deemed an Exempted Person under the Second Restated Rights Agreement cannot trigger any of the Rights provided therein so long as such Exempted Person complies with the terms and conditions by which the Board approved such exemption from the Restated Rights Agreement.

As previously disclosed, on October 8, 2015, ~~the Company~~we entered into a Letter Agreement (the “Agreement”) by and between ~~the Company~~Amtech and certain shareholders of ~~the Company~~Amtech who jointly file (the “Joint Filers”) under Section 13 of the Securities Exchange Act of 1934, as ~~amended (the “Exchange Act”).~~amended. One of the Joint Filers became a member of our Board after the Agreement was approved by the Board. The Agreement permits the Joint Filers, pursuant to the Second Restated Rights Agreement, to individually acquire shares of common stock of ~~the Company~~Amtech that would, in the aggregate, bring the Joint Filers’ collective

ownership to no more than 19.9% of ~~the Company’s~~our issued and outstanding common stock at any time. In the event the Joint Filers’ collective ownership at any time exceeds 19.9% of ~~the Company’s~~our issued and outstanding shares of common stock, ~~the Company is~~we are entitled to specific performance and all other remedies entitled to ~~the Company~~us at law or equity, among others. ~~The Company’s board of directors~~Our Board approved the Agreement and transactions contemplated thereunder, and has the sole authority to terminate the Agreement at any time.

During the ~~quarter~~six months ended ~~December~~March 31, ~~2016,~~2017, SoLayTec borrowed ~~less than $0.1 million.~~approximately $0.1 million. The debt has interest rates ranging from 4.5% to 12.5% and maturity dates ranging from fiscal 2017 to fiscal 2021.

8. Commitments and Contingencies

Purchase Obligations – As of ~~December~~March 31, ~~2016~~2017, ~~the Company~~we had purchase obligations in the amount of ~~$14.2~~$29.1 million compared to $11.3 million as of September 30, 2016. These purchase obligations consist of outstanding purchase orders for goods and services. While the amount represents purchase agreements, the actual amounts to be paid may be less if any agreements are renegotiated, canceled or terminated.

Development ~~projects~~Projects – In fiscal 2014, our wholly owned subsidiary, Tempress Systems, Inc. ~~("Tempress"~~(“Tempress”), entered into an agreement with the Energy Research Centre of the Netherlands ~~("ECN"~~(“ECN”), a Netherlands ~~government sponsored~~government-sponsored research institute, for a joint research and development project. Under the terms of the agreement, Tempress sold an ion implanter ~~("Equipment"~~(“Equipment”) to ECN for $1.4 million. Both Tempress and ECN are performing research and development projects utilizing the Equipment at the ECN facilities. Each party to the agreement will have 100% rights to the results of the projects developed separately by the individual parties. Any results co-developed will be jointly owned. ~~Over the four-year period of the agreement,~~ Tempress ~~is required~~met its requirement to contribute $1.4 million to the project in the form of installation of the equipment, acceptance testing, project meeting attendance, training, parts, and service, including keeping the equipment in good condition and repair for the first two years of the ~~agreement. As of December 31, 2016, Tempress has contributed all of the required $1.4 million~~agreement prior to ~~the project.~~fiscal 2017.

EPA Accrual -– As a result of the BTU acquisition, ~~the Company~~we assumed BTU’s proportional responsibility for clean-up costs at a Superfund site. As an equipment manufacturer, BTU generated and disposed of small quantities of solid waste that were considered hazardous under Environment Protection Agency (“EPA”) regulations. Because BTU historically used a waste disposal firm that disposed of the solid waste at a site that the EPA designated as a Superfund site, BTU was named by the EPA as one of the entities responsible for a portion of the expected clean-up costs. Based on ~~the Company's~~our proportional responsibility, as negotiated with and agreed to by the EPA, ~~the Company's~~our liability related to this matter is less than $0.1 million, which is included in Other Accrued Liabilities on the Condensed Consolidated Balance Sheets as of ~~December~~March 31, ~~2016~~2017 and September 30, 2016. In accordance with the agreement, ~~the Company~~we established a letter of credit for $0.2 million to the benefit of the EPA for potential cash payments as settlements for ~~the Company’s~~our proportional liability.

Legal Proceedings –– The Company and its subsidiaries are defendants from time to time in actions for matters arising out of their business operations. ~~The Company does~~We do not believe that any matters or proceedings presently pending will have a material adverse effect on ~~its~~our consolidated financial position, results of operations or liquidity.

As previously disclosed in ~~the Company’s~~our filings with the SEC, shortly after ~~the Company~~we entered into the merger agreement with BTU, two separate putative stockholder class action complaints (together, the ~~"Stockholder Actions"~~“Stockholder Actions”) were filed in the Court of Chancery of the State of Delaware (the ~~"Delaware Court"~~“Delaware Court”). The first was filed on November 4, 2014 and the second on November 17, 2014, on behalf of BTU’s public stockholders, against BTU, members of the BTU board, Amtech and the special purpose merger subsidiary. The Stockholder Actions were consolidated on December 4, 2014. The complaints generally alleged that, in connection with entering into the merger agreement, the BTU board of directors breached certain fiduciary duties owed to ~~BTU's~~BTU’s stockholders. The complaints sought various forms of declaratory and injunctive relief, as well as compensatory damages.

On February 18, 2016, the Delaware Court entered the Order approving the Amended Stipulation of Settlement. As a result, the Released Claims were dismissed with prejudice and without any admission of wrongdoing by any of the parties to the Stockholder Actions. Pursuant to the Amended Stipulation of Settlement, BTU, its insurer(s), or its successor(s) in interest are responsible for payment of fees and expenses in the amount of $325,000 which were paid in full on April 1, 2016.

As described above, the Released Claims are limited solely to claims related to any disclosures (or lack thereof) to BTU’s stockholders concerning the merger and any fiduciary claims concerning the decision to enter into the merger. While we are currently unaware of any other pending or threatened litigation related to additional claims arising from the Stockholder Actions, any future claims are uncertain, so additional harm could potentially result ~~to the Company~~ from this litigation, which may cause ~~the Company~~us to incur substantial costs and divert management’s attention from operational matters.

9. Investments

~~The Company’s equity method investments include~~Our long-term investment consists of a 15% interest in Kingstone Technology Hong Kong Limited (“Kingstone”). ~~The Company recognizes its~~We recognize our portion of net income or losses on a one-quarter lag. The carrying value of the equity method investment in Kingstone was $2.9 million and $3.0 million as of ~~December~~March 31, ~~2016~~2017 and September 30, 2016, respectively. For the ~~three~~six months ended ~~December~~March 31, ~~2016~~2017 we recognized investment loss of $0.1 million. For the three and six months ended ~~December~~March 31, ~~2015, the~~2016, we recognized investment ~~loss was not material to our consolidated statement~~income of ~~operations.~~$0.7 million.

10. Related Party Transactions

In ~~the fourth quarter of~~fiscal 2015, ~~the Company~~we deconsolidated Kingstone, reducing ~~its~~our ownership to 15% of Kingstone Hong Kong, the Hong Kong holding company. Upon the deconsolidation, Kingstone became a related party of the Company. At ~~December~~March 31, ~~2016,~~2017 and September 30, 2016, ~~the Company's~~our accounts receivable due from Kingstone were $0.3 million, which are included in Accounts Receivable on the Condensed Consolidated Balance Sheet.

As of ~~December~~March 31, ~~2016,~~2017, SoLayTec has borrowed approximately ~~$1.2~~$1.3 million from its shareholder, TNO Technostarters B.V. The loans have varying interest rates from 9.5% to 12.5% and mature in 2021.

~~11. Subsequent Event~~

As a result of customer deposits received after the end of the quarter, cash, cash equivalents, and restricted cash increased to $45.8 million as of January 31, 2017, compared to cash, cash equivalents, and restricted cash of $26.9 million, as of December 31, 2016.

Introduction

Management’s Discussion and Analysis (“MD&A”) is intended to facilitate an understanding of our business and results of operations. MD&A consists of the following sections:

Overview

Liquidity and Capital Resources

~~Off – Balance~~Off-Balance Sheet Arrangements

Contractual Obligations

Critical Accounting Policies

Impact of Recently Issued Accounting Pronouncements

Overview

We operate in three reportable business segments: (i) solar, (ii) semiconductor and (iii) polishing. In our solar segment, we are a leading global supplier of thermal processing systems, including diffusion, plasma-enhanced chemical vapor deposition (“PECVD”), atomic layer deposition (“ALD”), and related automation, parts and services, to the solar/photovoltaic industry. In our semiconductor segment, we supply thermal processing equipment, including solder reflow equipment and related controls for use by leading semiconductor manufacturers, and in electronics assembly for automotive and other industries. In our polishing ~~supplies~~ segment, we produce consumables and machinery for lapping (fine abrading) and polishing of materials, such as sapphire substrates, optical components, silicon wafers, numerous types of crystalline materials, ceramics and metal components.

Our customers are primarily manufacturers of solar cells and integrated circuits. The solar cell and semiconductor industries are cyclical and historically have experienced significant fluctuations. Our revenue is impacted by these broad industry trends. Since 2012, the solar cell industry has experienced a structural imbalance between supply and demand. This imbalance has increased competitive pressure on selling prices and negatively impacted our results of operations. We believe that at least several solar cell manufacturers are now producing at near practical capacity, which is consistent with recently announced cell capacity expansion plans within the industry. Our ~~strategy has been,~~high throughput equipment platforms, technologies for higher cell efficiency, and ~~continues~~greater knowledge of the complete cell manufacturing process have contributed significantly to ~~be,~~our success in securing the large turnkey orders announced in January and April of 2017 from a new solar cell manufacturer in China. For individual equipment orders, we compete with Chinese equipment manufacturers that offer lower prices coupled with liberal payment terms. Thus, we are finding it more difficult to ~~grow~~participate in the ~~Company through strategic product development~~capacity expansions of those Chinese companies that already have significant experience with all facets of producing solar cells and ~~acquisitions.~~

at least some prior experience working with the local equipment vendors. While we will continue to focus on developing advanced products and technologies, we plan to seek further cost reductions to address the competition from Chinese equipment vendors.

Net Revenue

Net revenue consists of revenue recognized upon shipment or installation of equipment, with the exception of products using new technology, for which revenue is recognized upon customer acceptance. Spare parts sales are recognized upon shipment and service revenue is recognized upon completion of the service activity or ratably over the term of the service contract. Since the majority of our revenue is generated from large system sales, revenue and operating income can be significantly impacted by the timing of system shipments, and recognition of revenue based on customer acceptances.

We shipped our first complete PERC solution (PECVD and ALD combined) during the quarter-ended December 31, 2016. As a new technology offering, all of the revenue associated with this shipment is deferred until acceptance and accounts for the increased deferred revenue. Due to a large n-type bi-facial turnkey order received in January 2017, revenue is expected to increase significantly in the second half of fiscal 2017.

Revenue from the semiconductor segment increased ~~47%~~28% compared to the prior year quarter due primarily to shipments of thermal processing systems and diffusion furnaces. Revenue from the polishing segment increased 35% compared to the prior year quarter due primarily to increased customer demand.

Net revenue for the six months ended March 31, 2017 and 2016 was $62.1 million and $44.6 million, respectively, an increase of $17.5 million or 39%.

as discussed above.

Backlog and Orders

Our order backlog as of ~~December~~March 31, 2017 and 2016 ~~and 2015~~ was ~~$51.5~~$87.4 million and ~~$42.9~~$67.3 million, respectively, an increase of ~~$8.6~~$20.1 million or ~~20%~~30%. Our backlog as of ~~December~~March 31, ~~2016~~2017 includes approximately ~~$35.8~~$66.9 million of orders and deferred revenue from our solar industry customers, compared to ~~$31.3~~$51.3 million at ~~December~~March 31, ~~2015.~~2016. New orders booked in the quarter ended ~~December~~March 31, ~~2016~~2017 were ~~$34.7~~$68.2 million ($~~15.9~~46.9 million solar) compared to ~~$35.6~~$45.0 million ($~~23.0~~28.0 million solar) of customer orders in the quarter ended ~~December~~March 31, ~~2015.~~2016. As of ~~December~~March 31, ~~2016 three customers~~2017, one customer individually accounted for ~~20%, 17% and 12%~~51% of our ~~backlog. The~~ backlog, ~~as of December 31, 2016 and the orders booked during that quarter, do not include~~primarily related to the n-type bi-facial turnkey order ~~included~~discussed in the January 24, 2017 order announcement, with which we concurrently received a large customer deposit. The large turnkey order announced in January 2017 (“Phase I”) is expected to ship in the third and fourth quarters of this fiscal year. A meaningful portion of the revenue from Phase I will be deferred until installation and acceptance, which is expected in fiscal 2018. The large follow-on turnkey order announced in April 2017 (“Phase II”) is not included in the backlog as of March 31, 2017 and is expected to ship in the first half of fiscal 2018, with a deferral of revenue similar to Phase I. The orders included in our backlog are generally credit approved customer purchase orders believed to be firm and are generally expected to ship within the next twelve months. Because our orders are typically subject to cancellation or delay by the customer, our backlog at any particular point in time is not necessarily representative of actual sales for succeeding periods, nor is backlog any assurance that we will realize profit from completing these orders. Our backlog also includes revenue deferred pursuant to our revenue recognition policy, derived from orders that have already been shipped, but which have not met the criteria for revenue recognition.

Gross Profit and Gross Margin

Gross profit is the difference between net revenue and cost of goods sold. Cost of goods sold consists of purchased material, labor and overhead to manufacture equipment and spare parts and the cost of service and support to customers for installation, warranty and paid service calls. Gross margin is gross profit as a percent of net revenue.

Gross profit for the three months ended ~~December~~March 31, ~~2016~~2017 and ~~2015~~2016 was $8.4 million ~~(29%~~(25% of ~~sales)~~net revenue) and $6.0 million (27% of ~~sales)~~net revenue), respectively, an increase of $2.4 million. Gross margin on products from our solar segment decreased compared to the three months ended March 31, 2016, due primarily to a net deferral of profit compared to a net recognition of previously deferred profit. Additionally, during the 2017 period there was less usage of previously reserved inventory. Gross margin on products from our semiconductor segment increased primarily due to higher sales volumes, improved product mix, and higher capacity utilization. Gross profit on products from our polishing segment increased, while gross margin decreased primarily due to higher sales of lower margin products. For the three months ended March 31, 2017, we deferred gross profit of $1.2 million. For the three months ended March 31, 2016, we recognized previously-deferred gross profit of $0.8 million. Deferred commissions are included in selling, general and administrative expenses (“SG&A”).

Gross profit for the six months ended March 31, 2017 and 2016 was $16.8 million (27% of net revenue) and $12.0 million (27% of net revenue), respectively, an increase of $4.9 million. Gross margin on products from our solar segment decreased compared to the first ~~three~~six months of fiscal 2016, ~~as the higher gross margin~~ due primarily to ~~sales volume and better product mix was more than offset by the lower~~a net deferral of profit compared to a net recognition of previously deferred profit, and ~~lower cancellation fee revenue.~~less usage of previously reserved inventory.

Selling, General and Administrative

~~Selling, general and administrative expenses ("~~SG~~&A") consist~~&A consists of the cost of employees, consultants and contractors, facility costs, sales commissions, shipping costs, promotional marketing expenses, legal, accounting expenses and bad debt expense.

SG&A expenses for the three months ended ~~December~~March 31, 2017 and 2016 ~~and 2015~~ were ~~$7.0~~$8.3 million and ~~$7.6~~$7.4 million, respectively. SG&A ~~decreased~~increased compared to the prior year quarter due primarily to ~~collections~~higher commissions related to higher revenues.

SG&A expenses for the six months ended March 31, 2017 and 2016 were $15.3 million and $15.0 million, respectively. Compared to the six months ended March 31, 2016, the increase in SG&A, primarily due to higher commissions related to higher revenues, was mostly offset by the collection of previously reserved accounts receivable of approximately $1.0 million, partially offset by higher commissions resulting from higher shipments. SG&A expense includes $0.3 million of stock-based compensation expense for the three months ended December 31, 2016 and 2015.

Research, Development and Engineering

Research, development and engineering ("(“RD~~&E"~~&E”) expenses consist of the cost of employees, consultants and contractors who design, engineer and develop new products and processes as well as materials and supplies used in producing prototypes. We receive reimbursements through governmental research and development grants which are netted against these expenses when certain conditions have been met.

RD&E expense, net of grants earned, for the six months ended March 31, 2017, decreased $1.3 million compared to the six months ended March 31, 2016, due primarily to decreased spending on RD&E at our solar segment.

Gain on Sale of Other Assets

For the three and six months ended March 31, 2016, we recognized a gain of $2.6 million on the receipt of sale of our exclusive sales and service rights in the Kingstone Hong Kong Limited (“Kingstone”) solar ion implant equipment, with no comparable items in the fiscal 2017 period.

Income from Equity Method Investment

For the ~~three~~six months ended ~~December~~March 31, ~~2016~~2017 we recognized investment loss of ~~$0.1million~~$0.1 million, related to our 15% equity investment in Kingstone. ~~We did not recognize any~~For the three and six months ended March 31, 2016, we recognized investment income ~~or loss for the three months ended December 31, 2015.~~of $0.7 million.

Income Taxes

For the three and six months ended ~~December~~March 31, ~~2016 and 2015~~2017 we recorded income tax expense of ~~$0.1~~$0.2 million and $0.3 million, respectively. For the three and six months ended March 31, 2016 we recorded income tax expense of $1.7 million and $2.0 million, respectively. The income tax provisions are based upon estimates of annual income, annual permanent differences and statutory tax rates in the various jurisdictions in which we operate, except that certain loss jurisdictions and discrete items are treated separately. The gain on the Kingstone transaction, described above, was treated as a discrete item and accounted for $1.7 million of the tax expense in the 2016 second fiscal quarter, with the tax calculated utilizing the effective tax rate and other discrete items nearly offsetting each other.

~~The Company establishes~~We establish a valuation allowance when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. A review of all available positive and negative evidence needs to be considered, including a ~~company's~~company’s performance, the market environment in which the company operates and the length of carryback and carryforward periods. According to those standards, it is difficult to conclude that a valuation allowance is not needed when the negative evidence includes cumulative losses in recent years. Therefore, cumulative losses weigh heavily in the overall assessment. As a result of the review, where cumulative losses had been incurred, we concluded in 2015 and 2016 that it was appropriate to maintain a full valuation allowance for substantially all net deferred tax assets in foreign jurisdictions and the carryforwards of U.S. net operating losses and foreign tax credits, which were acquired in the merger with BTU ~~International.~~International, Inc. Tax planning strategies to reduce sources of future taxable income caused us to conclude in the fourth quarter of fiscal 2016 that a valuation allowance should be established on the remaining U.S. deferred tax assets.

Liquidity and Capital Resources

At ~~December~~March 31, ~~2016,~~2017, and September 30, 2016, cash and cash equivalents were ~~$23.6~~$38.9 million and $27.7 million, ~~respectively. At December 31, 2016,~~respectively, and ~~September 30, 2016,~~ restricted cash was ~~$3.3~~$2.6 million and $0.9 million, respectively. Our working capital was ~~$45.4~~$44.6 million as of ~~December~~March 31, ~~2016~~2017 and $44.9 million as of September 30, 2016.

The ~~decrease~~increase in cash ~~for~~during the first ~~three~~six months of fiscal 2017 of ~~$4.0~~$11.2 million was primarily due to the significant customer deposit received in January 2017 by our Solar segment. The increased cash ~~used in operating activities~~will facilitate the fulfillment of ~~$3.5 million.~~that order. We maintain a portion of our cash and cash equivalents in Euros at our Dutch and French operations and in RMB in our Chinese operations; therefore, changes in the exchange rate have an impact on our cash balances. Restricted cash increased due to an increase in

customer deposits requiring bank guarantees collateralized by cash. Our ratio of current assets to current liabilities was 1.8:1 as of March 31, 2017, and 2.2:1 as of ~~December 31, 2016, and~~ September 30, 2016. We have never paid dividends on our common stock.

On January 24, 2017, we announced a significant n-type bi-facial turnkey order from a new customer in China. As a result of significant customer deposits from that and other orders both from Solar and Semiconductor, the balance of cash and cash equivalents increased by $18.5 million to $42.1 million as of January 31, 2017, compared to $23.6 million as of December 31, 2016. The increased cash will facilitate the fulfillment of those orders.

The success of our growth strategy is dependent upon the availability of additional capital resources on terms satisfactory to management. Our sources of capital in the past have included the sale of equity securities, which include common and preferred stock sold in private transactions and public offerings, capital leases, long-term debt and customer deposits. We believe that our principal sources of liquidity discussed above are sufficient to support operations for at least the next twelve months.

Cash Flows from Operating Activities

Cash ~~used in~~provided by our operating activities was $~~3.5~~11.6 million for the ~~three~~six months ended ~~December~~March 31, ~~2016,~~2017, compared to ~~$10.8~~$6.4 million used in ~~such activities~~operations for the ~~three~~six months ended ~~December~~March 31, ~~2015.~~2016. During the ~~three~~six months ended ~~December~~March 31, 2017, cash was provided primarily by an increase in customer deposits, partially offset by advances made to vendors and an increase in restricted cash. During the six months ended March 31, 2016, ~~cash~~net loss adjusted for non-cash items resulted in the use of $7.5 million, which was ~~reduced by increases in accounts receivable and restricted cash,~~partially offset by ~~decreases in inventory.

Cash Flows from Financing Activities

For the ~~three~~six months ended ~~December~~March 31, ~~2016,~~2017, $0.1 million of cash used by financing activities was primarily comprised of payments on long-term debt of ~~$0.2~~$0.3 million, net of borrowings of ~~less than~~ $0.1 million.

Off-Balance Sheet Arrangements

As of ~~December~~March 31, ~~2016,~~2017, Amtech had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K promulgated by the Securities and Exchange Commission.

Contractual Obligations

Purchase obligations were ~~$14.2~~$29.1 million as of ~~December~~March 31, ~~2016,~~2017, compared to $11.3 million as of September 30, 2016, an increase of ~~$2.9~~$17.8 million due primarily to ~~increased customer orders.~~the large solar order received in January 2017. Approximately $8.0 million of the March 31, 2017 obligation has been prepaid in the form of advances to vendors.

During the ~~three~~six months ended ~~December~~March 31, ~~2016,~~2017, SoLayTec B.V. borrowed an additional $0.1 million. As of ~~December~~March 31, ~~2016~~2017, the SoLayTec debt has a remaining balance of ~~$3.7~~$3.8 million, with interest capitalized per the agreement bearing interest at rates ranging from 4.5% to 12.5% and maturity dates ranging from fiscal 2017 to fiscal 2021.

Critical Accounting Policies

“Management’s Discussion and Analysis of Financial Condition and Results of Operations” discusses our condensed consolidated financial statements that have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the condensed consolidated financial statements, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.

On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, inventory valuation, accounts and notes receivable collectability, warranty and impairment of long-lived assets. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances. The results of these estimates and judgments form the basis for making conclusions about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

A critical accounting policy is one that is both important to the presentation of our financial position and results of operations, and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. These uncertainties are discussed in Part I, Item 1A of our Annual Report on Form 10-K, as amended, for the year ended September 30, 2016. We believe our critical accounting policies relate to the more significant judgments and estimates used in the preparation of our consolidated financial statements.

We believe the critical accounting policies discussed in the section entitled “Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” in our Annual Report on Form 10-K, as amended, for the fiscal year ended September 30, 2016 represent the most significant judgments and estimates used in the preparation of our consolidated financial statements. There have been no significant changes in our critical accounting policies during the ~~three~~six months ended ~~December~~March 31, ~~2016.~~2017.

Impact of Recently Issued Accounting Pronouncements

For discussion of the impact of recently issued accounting pronouncements, see ~~“Item~~“Part I, Item 1: Financial Information” under “Impact of Recently Issued Accounting Pronouncements”.


Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to foreign currency exchange rates to the extent sales contracts, purchase contracts, assets or liabilities of our operations are denominated in currencies other than their functional currency. Our operations in the United States are generally conducted in U.S. dollars. Our operations in Europe, China and other countries conduct business primarily in their respective functional currencies, but occasionally we enter into transactions in non-functional currencies. It is highly uncertain how currency exchange rates will fluctuate in the future. Actual changes in foreign exchange rates could adversely affect our operating results or financial condition.

During fiscal 2016 and in the first ~~three~~six months of fiscal 2017, we did not hold any stand-alone or separate derivative instruments. We incurred net foreign currency transaction losses of ~~less than~~ $0.1 million during the six month period ended March 31, 2017, and net foreign currency transaction gains of $0.1 million during the ~~three months~~six month period ended ~~December~~March 31, ~~2016 and 2015, respectively.~~2016.

We incurred a foreign currency translation ~~losses~~loss of ~~$0.9~~$0.6 million and ~~$0.5~~a gain of $0.1 million during the ~~three~~six months ended ~~December~~March 31, ~~2016~~2017 and ~~2015,~~2016, respectively, a type of other comprehensive ~~loss,~~income (loss), which is a direct adjustment to stockholders’ equity. Our net investment in and advances to our foreign operations totaled ~~$49.2~~$47.7 million as of ~~December~~March 31, ~~2016.~~2017. A 10% change in the value of the foreign currencies relative to the U.S. dollar would cause approximately $5.0 million of other comprehensive income (loss).

As of ~~December~~March 31, ~~2016,~~2017, sales commitments denominated in a currency other than the functional currency of our transacting operation totaled approximately ~~$15.6~~$15.3 million. Our lead-times to fulfill these commitments generally range between 13 and 26 weeks. A 10% change in the relevant exchange rates between the time the order was taken and the time of shipment cause our gross profit on such orders to be ~~$1.6~~$1.5 million greater or less than expected on the date the order was taken.

As of ~~December~~March 31, ~~2016,~~2017, purchase commitments denominated in a currency other than the functional currency of our transacting operation totaled ~~$2.4~~$3.7 million. A 10% change in the relevant exchange rates between the time the purchase order was placed and the time the order is received would not cause our cost of such items to be significantly greater or less than expected on the date the purchase order was placed.


Item 4.	CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), has carried out an evaluation of the effectiveness of our disclosure controls and procedures as of ~~December~~March 31, ~~2016,~~2017, pursuant to Exchange Act Rules 13a-15(e) and 15(d)-15(e). Disclosure controls and procedures means controls and other procedures that are designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange ~~Commission's~~Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including the principal executive and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon that evaluation, our CEO and CFO have concluded that as of such date, our disclosure controls and procedures in place were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in ~~Amtech's~~Amtech’s internal control over financial reporting during the ~~three~~six months ended ~~December~~March 31, ~~2016~~2017 that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

PART II. OTHER INFORMATION


Item 1.	Legal Proceedings

The Company and its subsidiaries are defendants from time to time in actions for matters arising out of their business operations. The Company does not believe that any matters or proceedings presently pending will have a material adverse effect on its consolidated financial position, results of operations or liquidity. As previously disclosed in the Company’s filings with the SEC, shortly after the Company entered into the merger agreement with BTU, two separate putative stockholder class action complaints (together, the ~~"Stockholder Actions"~~“Stockholder Actions”) were filed in the Court of Chancery of the State of Delaware (the ~~"Delaware Court"~~“Delaware Court”). The first was filed on November 4, 2014 and the second on November 17, 2014, on behalf of BTU’s public stockholders, against BTU, members of the BTU board, Amtech and the special purpose merger subsidiary. The Stockholder Actions were consolidated on December 4, 2014. The complaints generally alleged that, in connection with entering into the merger agreement, the BTU board of directors breached certain fiduciary duties owed to ~~BTU's~~BTU’s stockholders. The complaints sought various forms of declaratory and injunctive relief, as well as compensatory damages.

As described above, the Released Claims are limited solely to claims related to any disclosures (or lack thereof) to BTU’s stockholders concerning the merger and any fiduciary claims concerning the decision to enter into the merger. While we are currently unaware of any other pending or threatened litigation related to additional claims arising from the Stockholder Actions, any future claims are uncertain, so additional harm could potentially result to the Company from this litigation, which may cause the Company to incur substantial costs and divert management’s attention from operational matters.


Item 1A.	Risk Factors

The most significant risk factors applicable to Amtech are described in Part I, Item 1A (Risk Factors) of Amtech’s Annual Report on Form 10-K, as amended, for the fiscal year ended September 30, 2016. There have been no material changes to the risk factors previously disclosed in our Form 10-K, as amended, for the fiscal year ended September 30, ~~2016.~~2016, other than as described in the Overview above, and the supplemental risk factors set forth below:

If the United States were to withdraw from or materially modify ~~NAFTA or~~ certain ~~other~~ international trade agreements, or change tax provisions related to the global manufacturing and sales of our products, our financial condition and results of operations could be adversely ~~affected~~.affected.

A portion of our business activities are conducted in foreign countries, including China, Malaysia, Taiwan, and the Netherlands. Our business benefits from free trade agreements, ~~such as the North American Free Trade Agreement (“NAFTA”)~~ and we also rely on various U.S. corporate tax provisions related to international commerce as we build, market and sell our products globally. The current presidential administration has made comments suggesting that heit is not supportive of certain existing international trade ~~agreements, including NAFTA.~~agreements. At this time, it remains unclear what ~~President Trump would or would not~~the current presidential administration will do with respect to these international trade agreements and U.S. tax provisions related to international commerce. Any action to withdraw from or materially modify ~~NAFTA or certain other~~ international trade agreements, or change corporate tax policy related to international commerce, could adversely affect our financial condition and results of operations.

The number of turnkey project order opportunities is uncertain and such projects may increase our risks relating to current and future performance, project management, supplier fulfillment, unforeseen site conditions, and the regulatory environment, which could have a material adverse effect on our financial condition and results of operations.

A turnkey project is a complete solar cell manufacturing line, including equipment manufactured by third parties, and the design, delivery, installation, start-up, and qualification of the entire line. While we have successfully participated in turnkey projects in the past, historically, those and other orders have been for shipments of our equipment. The demand for turnkey projects from our customers can fluctuate significantly, and, therefore, the magnitude and frequency of previously announced turnkey orders may not be indicative of future turnkey orders or our financial performance. Additionally, turnkey orders may provide additional risks to us in executing the project, such as:

project management, including potentially lower-than-expected revenue due to project delays and cost over-runs;

organizational stress/burden that could impact order fulfillment of other orders;

project duration and customer acceptance;

use of and reliance on subcontractors;

supplier relationships and constraints;

pricing and fulfillment;

turnkey site conditions, such as readiness of customer facilities and access restrictions; and

local regulations and policies.

Such risks could make it difficult or impossible to complete a turnkey order or cause us to incur unforeseen costs and expenses to complete a turnkey order. Failure to complete a turnkey order or unforeseen costs and expenses incurred in completing a turnkey order could have a material adverse effect on our financial condition and results of operations.
