Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies Nature of Operations and Basis of Presentation – Amtech Systems, Inc. (the “Company,” “Amtech,” “we,” “our” or “us”) is a leading, global manufacturer of capital equipment, including thermal processing and wafer handling automation, and related consumables used in fabricating semiconductor devices, light-emitting diodes, or LEDs, silicon carbide (SiC) and silicon power chips and solar cells. We sell these products to semiconductor and solar cell manufacturers worldwide, particularly in Asia, the United States and Europe. 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 our ability to develop or acquire and market profitable new products and on our ability to adapt to cyclical trends. In the second quarter of 2019, we began the process to divest our solar business. As such, we have classified substantially all of the Solar segment as held for sale in our Condensed Consolidated Balance Sheets and reported its results as discontinued operations in our Condensed Consolidated Statements of Operations. For additional information on the divestiture, see Note 4. For additional information on our segments, see Note 10. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. 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 for the fiscal year ended September 30, 2018. Our fiscal year is from October 1 to September 30. Unless otherwise stated, references to the years 2019 and 2018 relate to the fiscal years ended September 30, 2019 and 2018, respectively. The consolidated results of operations for the three and six months ended March 31, 2019, 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 our wholly-owned subsidiaries. All significant intercompany balances 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. Reclassifications – Certain reclassifications have been made to prior year financial statements to conform to the current year presentation. Results for all periods presented in this report have been reclassified for discontinued operations (Note 4) and for changes to our reportable segments (Note 10). These reclassifications had no effect on the previously reported consolidated financial statements for any period. Divestitures – Significant accounting policies associated with a decision to dispose of a business are discussed below: Discontinued Operations – A business is classified as discontinued operations if the disposal represents a strategic shift that will have a major effect on operations or financial results and meets the criteria to be classified as held for sale or is disposed of by sale or otherwise. Significant judgments are involved in determining whether a business meets the criteria for discontinued operations reporting and the period in which these criteria are met. If a business is reported as a discontinued operation, the results of operations through the date of sale, including any gain or loss recognized on the disposition, are presented on a separate line of the Condensed Consolidated Statement of Operations. Interest on debt directly attributable to the discontinued operation is allocated to discontinued operations. Assets Held for Sale – An asset or business is classified as held for sale when (i) management commits to a plan to sell and it is actively marketed; (ii) it is available for immediate sale and the sale is expected to be completed within one year; and (iii) it is unlikely significant changes to the plan will be made or that the plan will be withdrawn. In isolated instances, assets held for sale may exceed one year due to events or circumstances beyond our control. The assets and related liabilities are aggregated and reported on separate lines of the Condensed Consolidated Balance Sheets. Shipping Expense – Shipping expenses of $0.2 million in each of the three months ended March 31, 2019 and 2018, and $0.5 million and $0.4 million for the six months ended March 31, 2019 and 2018, respectively, are included in selling, general and administrative expenses. Research, Development and Engineering Expense – The table below shows gross research and development expenses and grants earned, in thousands:
| Three Months Ended March 31, |  | Six Months Ended March 31,
| 2019 |  | 2018 |  | 2019 |  | 2018

Net research, development and engineering | $ | 713 |  |  | $ | 778 |  |  | $ | 1,579 |  |  | $ | 1,453 |
Concentrations of Credit Risk – Our customers consist primarily of semiconductor manufacturers worldwide, as well as the lapping and polishing marketplace. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and trade accounts receivable. Credit risk is managed by performing ongoing credit evaluations of the customers’ financial condition, by requiring significant deposits where appropriate, and by actively monitoring collections. Letters of credit are required of certain customers depending on the size of the order, type of customer or its creditworthiness, and country of domicile. As of March 31, 2019, one Semiconductor segment customer individually represented 11% of accounts receivable. As of September 30, 2018, one Semiconductor customer individually represented 16% of accounts receivable. We maintain our cash, cash equivalents and restricted cash in multiple financial institutions. Balances in the United States, which account for approximately 80% and 88% of total cash balances at our continuing operations as of March 31, 2019 and September 30, 2018, respectively, are primarily invested in U.S. Treasuries or are in financial institutions insured by the Federal Deposit Insurance Corporation (“FDIC”). The remainder of our cash is maintained with financial institutions with reputable credit ratings in the Netherlands, China, France, the United Kingdom, Singapore and Malaysia. We maintain cash in bank accounts in amounts which at times may exceed federally insured limits. We have not experienced any losses on such accounts. Refer to Note 11 to Condensed Consolidated Financial Statements for information regarding major customers, foreign sales and revenue in other countries subject to fluctuation in foreign currency exchange rates. Impact of Recently Issued Accounting Pronouncements See Note 2 for information on our adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), which amends the existing accounting standards for revenue recognition. The adoption of ASC 606 did not have a material effect on our results of operations. In November 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-18, “Statement of Cash Flows: Restricted Cash.” The amendments address diversity in practice that exists in the classification and presentation of changes in restricted cash and require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. We adopted this standard retrospectively effective October 1, 2018, and, accordingly, to conform to the current period presentation, we reclassified our restricted cash to be included in the total of cash and cash equivalents presented at the bottom of our consolidated statements of cash flows for both the beginning and ending periods for our six months ended March 31, 2019 and 2018. As a result, the amount of the change in our net cash provided by operating activities no longer separately shows the change in restricted cash for either period. The following table summarizes the effects related to the adoption of ASU 2016-18 for the six months ended March 31, 2018:
| March 31, 2018
| As reported |  | As adjusted
Net cash used in operating activities | $ | (1,805 | ) |  | $ | (17,515 | )
Effect of Exchange Rate Changes on Cash, Cash Equivalents and Restricted Cash | $ | 640 |  |  | $ | 1,372 |
Net Decrease in Cash, Cash Equivalents and Restricted Cash | $ | (626 | ) |  | $ | (15,604 | )
Cash, Cash Equivalents and Restricted Cash, Beginning of Period | $ | 51,121 |  |  | $ | 75,761 |
Cash, Cash Equivalents and Restricted Cash, End of Period | $ | 50,495 |  |  | $ | 60,157 |
There have been no other material changes or additions to the recently issued accounting standards other than those previously reported in Note 1 to our Consolidated Financial Statements in Part II, Item 8 of our Annual Report on Form 10-K for the year ended September 30, 2018 that affect or may affect our financial statements.
