The Company's operating results depend upon the capital and operating expenditures of semiconductor device manufacturers, integrated device manufacturers, outsourced semiconductor assembly and test providers (“OSATs”), and other electronics manufacturers, including automotive electronics suppliers, worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry's demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, including those sold by the Company. These downturns and slowdowns have in the past adversely affected the Company's operating results. The Company believes such volatility will continue to characterize the industry and the Company's operations in the future.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Use of Estimates</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The preparation of consolidated financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory, carrying value and lives of fixed assets, goodwill and intangible assets, income taxes, equity-based compensation expense, and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company's assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates.</span></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Vulnerability to Certain Concentrations</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Financial instruments which may subject the Company to concentrations of credit risk as of </span><span style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;">September 28, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;">September 29, 2018</span><span style="font-family:inherit;font-size:10pt;"> consisted primarily of trade receivables. The Company manages credit risk associated with investments by investing its excess cash in highly rated debt instruments of the U.S. government and its agencies, financial institutions, and corporations. The Company has established investment guidelines relative to diversification and maturities designed to maintain safety and liquidity. These guidelines are periodically reviewed and modified as appropriate. The Company does not have any exposure to sub-prime financial instruments or auction rate securities. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's trade receivables result primarily from the sale of semiconductor equipment, related accessories and replacement parts, and tools to a relatively small number of large manufacturers in a highly concentrated industry. Write-offs of uncollectible accounts have historically not been significant. The Company actively monitors its customers' financial strength to reduce the risk of loss. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's products are complex and require raw materials, components and subassemblies having a high degree of reliability, accuracy and performance. The Company relies on subcontractors to manufacture many of these components and subassemblies and it relies on sole source suppliers for some important components and raw material inventory.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Foreign Currency Translation and Remeasurement</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The majority of the Company's business is transacted in U.S. dollars; however, the functional currencies of some of the Company's subsidiaries are their local currencies. In accordance with ASC No. 830, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Foreign Currency Matters</span><span style="font-family:inherit;font-size:10pt;"> (“ASC 830”), for a subsidiary of the Company that has a functional currency other than the U.S. dollar, gains and losses resulting from the translation of the functional currency into U.S. dollars for financial statement presentation are not included in determining net income, but are accumulated in the cumulative translation adjustment account as a separate component of shareholders' equity (accumulated other comprehensive income / (loss)). Under ASC 830, cumulative translation adjustments are not adjusted for income taxes as they relate to indefinite investments in non-U.S. subsidiaries. Gains and losses resulting from foreign currency transactions are included in the determination of net income.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's operations are exposed to changes in foreign currency exchange rates due to transactions denominated in currencies other than the location's functional currency. The Company is also exposed to foreign currency fluctuations that impact the remeasurement of net monetary assets of those operations whose functional currency, the U.S. dollar, differs from their respective local currencies, most notably in Israel, Singapore and Switzerland. In addition to net monetary remeasurement, the Company has exposures related to the translation of subsidiary financial statements from their functional currency, the local currency, into its reporting currency, the U.S. dollar, most notably in the Netherlands, China, Taiwan, Japan and Germany. The Company's U.S. operations also have foreign currency exposure due to net monetary assets denominated in currencies other than the U.S. dollar.</span></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Derivative Financial Instruments </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company’s primary objective for holding derivative financial instruments is to manage the fluctuation in foreign exchange rates and accordingly is not speculative in nature. The Company’s international operations are exposed to changes in foreign exchange rates as described above. The Company has established a program to monitor the forecasted transaction currency risk to protect against foreign exchange rate volatility. Generally, the Company uses foreign exchange forward contracts in these hedging programs. These instruments, which have maturities of up to twelve months, are recorded at fair value and are included in prepaid expenses and other current assets, or accrued expenses and other current liabilities. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Our accounting policy for derivative financial instruments is based on whether they meet the criteria for designation as a cash flow hedge. A designated hedge with exposure to variability in the functional currency equivalent of the future foreign currency cash flows of a forecasted transaction is referred to as a cash flow hedge. The criteria for designating a derivative as a cash flow hedge include the assessment of the instrument’s effectiveness in risk reduction, matching of the derivative instrument to its underlying transaction, and the assessment of the probability that the underlying transaction will occur. For derivatives with cash flow hedge accounting designation, we report the after-tax gain / (loss) from the effective portion of the hedge as a component of accumulated other comprehensive income / (loss) and reclassify it into earnings in the same period in which the hedged transaction affects earnings and in the same line item on the consolidated statement of operations as the impact of the hedged transaction. Derivatives that we designate as cash flow hedges are classified in the consolidated statement of cash flows in the same section as the underlying item, primarily within cash flows from operating activities. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The hedge effectiveness of these derivative instruments is evaluated by comparing the cumulative change in the fair value of the hedge contract with the cumulative change in the fair value of the forecasted cash flows of the hedged item.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">If a cash flow hedge is discontinued because it is no longer probable that the original hedged transaction will occur as previously anticipated, the cumulative unrealized gain or loss on the related derivative is reclassified from accumulated other comprehensive income / (loss) into earnings. Subsequent gain / (loss) on the related derivative instrument is recognized into earnings in each period until the instrument matures, is terminated, is re-designated as a qualified cash flow hedge, or is sold. Ineffective portions of cash flow hedges, as well as amounts excluded from the assessment of effectiveness, are recognized in earnings.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Cash Equivalents </span><span style="font-family:inherit;font-size:10pt;font-weight:bold;"> </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents.

If the financial condition of the Company's customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company is also subject to concentrations of customers and sales to a few geographic locations, which could also impact the collectability of certain receivables. If global or regional economic conditions deteriorate or political conditions were to change in some of the countries where the Company does business, it could have a significant impact on the results of operations, and the Company's ability to realize the full value of its accounts receivable.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Inventories</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Inventories are stated at the lower of cost (on a first-in, first-out basis) or net realizable value. The Company generally provides reserves for obsolete inventory and for inventory considered to be in excess of demand. Demand is generally defined as </span><span style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"><span>18 months</span></span><span style="font-family:inherit;font-size:10pt;"> forecasted future consumption for equipment, </span><span style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"><span>24 months</span></span><span style="font-family:inherit;font-size:10pt;"> forecasted future consumption for spare parts, and </span><span style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"><span>12 months</span></span><span style="font-family:inherit;font-size:10pt;"> forecasted future consumption for tools. Forecasted consumption is based upon internal projections, historical sales volumes, customer order activity and a review of consumable inventory levels at customers' facilities. The Company communicates forecasts of its future consumption to its suppliers and adjusts commitments to those suppliers accordingly. If required, the Company reserves the difference between the carrying value of its inventory and the lower of cost or net realizable value, based upon projections about future consumption, and market conditions. If actual market conditions are less favorable than projections, additional inventory reserves may be required.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Inventory reserve provision for certain subsidiaries is determined based on management's estimate of future consumption for equipment and spare parts.

ASC 360 also provides a single accounting model for long-lived assets to be disposed of by sale and establishes additional criteria that would have to be met to classify an asset as held for sale. The carrying amount of an asset or asset group is not recoverable to the extent it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. Estimates of future cash flows used to test the recoverability of a long-lived asset or asset group must incorporate the entity's own assumptions about its use of the asset or asset group and must factor in all available evidence.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">ASC 360 requires that long-lived assets be tested for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Such events include significant under-performance relative to historical internal forecasts or projected future operating results; significant changes in the manner of use of the assets; significant negative industry or economic trends; or significant changes in market capitalization. During the fiscal years ended </span><span style="font-family:inherit;font-size:10pt;">September 28, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">September 29, 2018</span><span style="font-family:inherit;font-size:10pt;">, no "triggering" events occurred. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Accounting for Impairment of Goodwill</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">ASC No. 350, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Intangibles - Goodwill and Other </span><span style="font-family:inherit;font-size:10pt;">("ASC 350") requires goodwill and other intangible assets with indefinite lives to be reviewed for impairment annually, or more frequently if circumstances indicate a possible impairment. We assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, a company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the impairment test is unnecessary. However, if a company concludes otherwise, then it is required to perform the goodwill impairment test. Following the Company's early adoption of ASU 2017-04, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Intangibles - Goodwill and Other (Topic 350):</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Simplifying the Test for Goodwill Impairment</span><span style="font-family:inherit;font-size:10pt;"> in the third quarter of fiscal 2017, the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment (i.e. step 2 of the goodwill impairment test) was eliminated. Accordingly, the Company's impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and recognizing an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value. </span></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As part of the annual evaluation, the Company performs an impairment test of its goodwill in the fourth quarter of each fiscal year to coincide with the completion of its annual forecasting and refreshing of its business outlook processes. On an ongoing basis, the Company monitors if a “triggering” event has occurred that may have the effect of reducing the fair value of a reporting unit below its respective carrying value. Adverse changes in expected operating results and/or unfavorable changes in other economic factors used to estimate fair values could result in a non-cash impairment charge in the future. </span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Impairment assessments inherently involve judgment as to the assumptions made about the expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the assumptions as to prices, costs, growth rates or other factors that may result in changes in the estimates of future cash flows. Although the Company believes the assumptions that it has used in testing for impairment are reasonable, significant changes in any one of the assumptions could produce a significantly different result. Indicators of potential impairment may lead the Company to perform interim goodwill impairment assessments, including significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition. </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">For further information on goodwill and other intangible assets, see Note 3 below.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Revenue Recognition</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In accordance with ASC No. 606, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers</span><span style="font-family:inherit;font-size:10pt;">, the Company recognizes revenue when we satisfy performance obligations as evidenced by the transfer of control of our products or services to customers.

While the Company has considered future taxable income and ongoing tax planning strategies in assessing the need for the valuation allowance, if it were to determine that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, an adjustment to the deferred tax asset would increase income in the period when such determination is made. Likewise, should the Company determine it would not be able to realize all or part of its net deferred tax assets in the future, an adjustment to the deferred tax asset would decrease income in the period when such determination is made.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company determines the amount of unrecognized tax benefit with respect to uncertain tax positions taken or expected to be taken on its income tax returns in accordance with ASC No. 740 Topic 10, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Income Taxes, General </span><span style="font-family:inherit;font-size:10pt;">(“ASC 740.10”). Under ASC 740.10, the Company utilizes a two-step approach for evaluating uncertain tax positions. Step one, or recognition, requires a company to determine if the weight of available evidence indicates a tax position is more likely than not to be sustained upon examination solely based on its technical merit. Step two, or measurement, is based on the largest amount of benefit, which is more likely than not to be realized on settlement with the taxing authority, including resolution of related appeals or litigation processes, if any.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Equity-Based Compensation </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company accounts for equity-based compensation under the provisions of ASC No. 718,</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> Compensation - Stock Compensation</span><span style="font-family:inherit;font-size:10pt;"> (“ASC 718”). ASC 718 requires the recognition of the fair value of the equity-based compensation in net income. Compensation expense associated with Relative TSR Performance Share Units is determined using a Monte-Carlo valuation model, and compensation expense associated with time-based and Special/Growth Performance Share Units is determined based on the number of shares granted and the fair value on the date of grant. See Note 9 for a summary of the terms of these performance-based awards. The fair value of the Company's stock option awards is estimated using a Black-Scholes option valuation model. The fair value of equity-based awards is amortized over the vesting period of the award, and the Company elected to use the straight-line method for awards granted after the adoption of ASC 718.</span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Earnings per Share </span></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Earnings per share (“EPS”) are calculated in accordance with ASC No. 260,</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> Earnings per Share</span><span style="font-family:inherit;font-size:10pt;">.

The fair value of the net assets acquired and the results of operations of the acquired businesses are included in the consolidated financial statements from the acquisition date forward.

Revenue related to the sale of services will generally continue to be recognized over time as the services are performed. In certain instances, where collection of consideration is not probable, recognition of revenue may occur later under the new model after we have completed all of our obligations under the contract. However, when adopting the new standard, we did not identify any balances where collection of consideration is not probable.
