Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). These footnotes condense or omit information and disclosures which substantially duplicate information provided in the Company’s latest audited financial statements. These unaudited consolidated financial statements should be read in conjunction with the financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments, including normal recurring accruals, necessary for a fair presentation of the results for the interim periods presented. The operating results for the three and nine months ended April 30, 2015 are not necessarily indicative of future trends or the Company’s results of operations for the entire fiscal year ending July 31, 2015.
	Certain prior period amounts on the balance sheet have been reclassified to conform to the current period presentation. Net income and shareholders’ equity were not affected by these reclassifications. The Company’s Consolidated Statements of Operations and Comprehensive Income (Loss) and Statements of Cash Flows for the three and nine months ended April 30, 2014 also reflect retroactive adjustments made by the Company to the bargain purchase gain reported as part of the Company’s acquisition of the ECT and Multitest businesses, which was reported in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014.
	The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation.
	Revenue Recognition
	The Company recognizes revenue based on guidance provided in Topic 605, Revenue Recognition, to the Financial Accounting Standards Board Codification (“FASB ASC”) and Accounting Standards Update 2009-13, Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price is fixed or determinable and collectability is reasonably assured.
	Revenue related to equipment sales is recognized when: (a) the Company has a written sales agreement; (b) delivery has occurred or service has been rendered; (c) the price is fixed or determinable; (d) collectability is reasonably assured; (e) the equipment delivered is a standard product with historically demonstrated acceptance; and (f) there is no unique customer acceptance provision or payment tied to acceptance or an undelivered element significant to the functionality of the system. Generally, payment terms are time based after product shipment. From time to time, sales to a customer may involve multiple elements, in which case revenue is recognized on the delivered element provided that (1) the undelivered element is a proven technology, (2) there is a history of acceptance on the equipment with the customer, (3) the undelivered element is not essential to the customer’s application, (4) the delivered item(s) has value to the customer on a stand-alone basis, and (5) if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The arrangement consideration, or the amount of revenue to be recognized on each separate unit of accounting, is allocated at the inception of the arrangement to all deliverables on the basis of their relative selling price.
	Revenue related to maintenance and service contracts is recognized ratably over the duration of the contracts. Net service sales as presented in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) includes revenue associated with LTX-Credence maintenance or service contracts only, and excludes ECT and Multitest. ECT and Multitest generally do not provide maintenance and service contracts, but rather sell spare parts and other components, and as a result these sales are recognized as net product sales in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss). Revenue related to spare parts and components is recognized when the four main criteria listed above are met. Generally customer acceptance is not required for spare parts and component sales.
	Inventories
	Inventories are stated at the lower of cost or market, determined on the first-in, first-out (“FIFO”) method, and include materials, labor and manufacturing overhead. The components of inventories are as follows:
		April 30,			July 31,
		2015			2014
		(in thousands)
	Material and purchased components	$	23,983		$	22,394
	Work-in-process		24,157			23,806
	Finished equipment, including inventory consigned to customers		15,632			23,470
	Total inventories	$	63,772		$	69,670
	The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market conditions. The Company regularly evaluates its ability to realize the value of inventory based on a combination of factors, including forecasted sales or usage, estimated product end of life dates, estimated current and future market value, and new product introductions.
	Purchasing and usage alternatives are also explored to mitigate inventory exposure. When recorded, reserves are intended to reduce the carrying value of inventory to its net realizable value. As of April 30, 2015 and July 31, 2014, inventory was stated net of inventory reserves of $48.0 million and $45.3 million, respectively. If actual demand for products deteriorates or market conditions are less favorable than projected, additional inventory reserves may be required. Such reserves are not reversed until the related inventory is sold or otherwise disposed of.
	Goodwill and Other Intangibles
	In accordance with FASB ASC Topic 350—Intangibles—Goodwill and Other (“ASC 350”), goodwill is not amortized. Rather, the Company’s goodwill is subject to periodic impairment testing. ASC 350 requires that the Company assign its goodwill to reporting units and test each reporting unit’s goodwill for impairment at least on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.
	The testing of goodwill for impairment is performed at a level referred to as a reporting unit. As of April 30, 2015, the Company currently has one reporting unit to which the full balance of goodwill is allocated, its semiconductor test reporting unit. Based on ASC 350-20-35-3A, as of April 30, 2015, there were no triggering events that required the Company to complete impairment testing.
	The Company’s goodwill consists of the following:
	Goodwill	April 30,			July 31,
		2015			2014
		(in thousands)
	Merger with Credence Systems Corporation (August 29, 2008)	$	28,662		$	28,662
	Acquisition of Step Tech Inc. (June 10, 2003)		14,368			14,368
	Acquisition of Titan Semiconductor Tool LLC (February 2, 2015)		870			—
	Total goodwill	$	43,900		$	43,030
	Amortizable intangible assets which relate to the acquisition of Titan Semiconductor Tool LLC (“Titan”), and the Acquired Businesses and the merger with Credence Systems Corporation (“Credence”), and the acquisition of Titan consist of the following, and are included in intangibles asset, net on the Company’s Consolidated Balance Sheets:
					As of April 30, 2015
	Description	Estimated			Gross Carrying			Accumulated			Net Amount

		(in years)			(in thousands)			(in thousands)			(in thousands)
	Developed technology (Credence, ECT, Multitest, and atg-Luther & Maelzer)		10-Jun		$	29,400		$	(25,880	)	$	3,520
	Customer Relationships – ECT, Multitest, atg-Luther & Maelzer		2			1,300			(498	)		802
	Maintenance agreements—ASL & Diamond		7			1,900			(1,357	)		543
	Total intangible assets				$	32,600		$	(27,735	)	$	4,865
	Intangible assets, other than trademarks owned by the Company, are amortized based upon the pattern of estimated economic use over their estimated useful lives. The weighted average estimated remaining useful life over which these intangible assets will be amortized is 4.7 years.
	The Company expects the remaining amortization for these intangible asset as of April 30, 2015 to be:
	Year ending July 31,	Amount
		(in thousands)
	2015	$	450
	2016		1,243
	2017		688
	2018		487
	Thereafter		1,829
	Total	$	4,697
	The identifiable intangible assets associated with the Dover Acquisition include $6.7 million of trademarks. The Company believes these trademarks will contribute to the Company’s cash flows indefinitely. Therefore, in accordance with ASC 350, the Company has assigned an indefinite useful life to the trademarks, and will not amortize the trademarks until their useful lives are no longer indefinite.
	Long Lived Assets
	On an on-going basis, management reviews the value of and period of amortization or depreciation of the Company’s long-lived assets. In accordance with Topic 360, Property, Plant and Equipment, to the FASB ASC, the Company reviews whether impairment losses exist on its long-lived assets other than goodwill when indicators of impairment are present. During this review, the Company assesses future cash flows and re-evaluates the significant assumptions used in determining the original cost of long-lived assets other than goodwill. Although the assumptions may vary, they generally include revenue growth, operating results, cash flows and other indicators of value. Management then determines whether there has been a permanent impairment of the value of long-lived assets based upon events or circumstances that have occurred since acquisition. The impairment amount recognized is based upon a determination of the impaired asset’s fair value compared to its carrying value. As of April 30, 2015, there were no indicators that required the Company to conduct a recoverability test.
	Foreign Currency Remeasurement
The financial statements of the Company’s foreign subsidiaries are remeasured in accordance with Topic 830, Foreign Currency Matters, to the FASB ASC. The functional currency of the Company’s tester group is the U.S. dollar. Accordingly, the Company’s foreign subsidiaries that are included in this group remeasure monetary assets and liabilities at month-end exchange rates while long-term non-monetary items are remeasured at historical rates. Income and expense accounts are remeasured at the average rates in effect during the month. Net gains (losses) resulting from foreign currency remeasurement and transaction gains (losses) are included in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss) as a component of other income, net, and were $(0.1) million and $(1.8) million, respectively for the three and nine months ended April 30, 2015 and $(0.3) million and $0.4 million, respectively for the three and nine months ended April 30, 2014. The functional currency of each of the Acquired Businesses is the local currency, predominantly Euro, Malaysian Ringgit and Singapore Dollars, and net gains or losses resulting from foreign currency remeasurement and translation gains or losses are recorded in stockholders’ equity as accumulated other comprehensive income (loss).
Product Warranty Costs
Certain of the Company’s products are sold with warranty provisions that require it to remedy deficiencies in quality or performance of products over a specified period of time at no cost to its customers. The Company generally offers a warranty for most of its products, the standard terms and conditions of which are based on the product sold and the customer. For all products sold, subject to a warranty, the Company accrues a liability for the estimated cost of standard warranty at the time of shipment. Factors that impact the warranty liability include the number of installed products, historical and anticipated product failure rates, material usage and service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts such amounts as necessary.
The following table shows the change in the Company’s product warranty liability, as required by Topic 460, Guarantees, to the FASB ASC for the nine months ended April 30, 2015 and 2014:
	Nine Months Ended
	April 30,
Product Warranty Activity	2015			2014
	(in thousands)
Balance at beginning of period	$	3,240		$	1,217
Warranty reserve acquired from ECT and Multitest		—			1,970
Warranty expenditures for current period		(3,752	)		(3,094	)
Changes in liability related to pre-existing warranties		(339	)		(96	)
Provision for warranty costs in the period		4,154			2,997
Balance at end of period	$	3,303		$	2,994
Engineering and Product Development Expenses
The Company expenses all engineering and product development expenses as incurred. Expenses relating to certain software development costs, which were subject to capitalization in accordance with Topic 485, Software, to the FASB ASC, were insignificant.
Shipping and Handling Costs
Shipping and handling costs are included in cost of sales in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss). Shipping and handling costs were insignificant for the three and nine months ended April 30, 2015 and 2014.
Income Taxes
Provision for income taxes relates principally to operating results of profitable foreign entities in jurisdictions primarily in Asia and Europe partially offset by a tax benefit recorded as a result of the Dover Acquisition, and the release of reserves due to statute of limitation expirations.
As of April 30, 2015 and July 31, 2014, the Company’s total liability for unrecognized income tax benefits was $5.9 million and $6.6 million, respectively (of which $2.3 million and $3.0 million, respectively, if recognized, would impact the Company’s income tax rate). The Company recognizes interest and penalties related to uncertain tax positions as a component of provision for income taxes. As of April 30, 2015 and July 31, 2014, the Company had accrued approximately $0.9 million and $1.0 million, respectively, for potential payment of accrued interest and penalties.
The Company conducts business globally and, as a result, the Company and its subsidiaries or branches file income tax returns in the U.S. federal jurisdiction and various U.S. state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as the United States, Singapore, Malaysia, China, France and Germany. With few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations for the years prior to 1998.
As a result of the Company’s merger with Credence on August 29, 2008, a greater than 50% cumulative ownership change in both entities triggered a significant limitation on net operating loss carryforward utilization. The Company’s ability to use acquired U.S. net operating loss and credit carryforwards is subject to annual limitation as defined in sections 382 and 383 of the Internal Revenue Code. The Company currently estimates that the annual limitation on its use of net operating losses generated through August 29, 2008 will be approximately $10.1 million which, based on currently enacted federal carryforward periods, limits the amount of net operating losses that are available for utilization to approximately $202.0 million. The Company has recorded a valuation allowance against the full value of U.S. net operating loss and credit carryforwards, and will continue to assess the realizability of these carryforwards in subsequent periods.
Accounting for Stock-Based Compensation
The Company has equity awards outstanding under various stock-based compensation plans, including the 2010 Stock Plan (“2010 Plan”), 2004 Stock Plan, 2001 Stock Plan, 1999 Stock Plan, and 1993 Stock Plan. In addition, the Company assumed the Credence 2005 Stock Incentive Plan in connection with its acquisition of Credence. The Company can only grant awards from the 2010 Plan.
During the three months ended April 30, 2015, the Company granted 112,167 Restricted Stock Units (“RSUs”), all of which are service-based and vest 25% per year for four years. The stock-based compensation expense related to these awards is recognized over their vesting periods.
The Company recognizes stock-based compensation expense on its equity awards in accordance with the provisions of Topic 718, Compensation—Stock Compensation to the FASB ASC (“Topic 718”). Under Topic 718, the Company is required to recognize as expense the estimated fair value as of the grant date of all share-based awards to employees. In accordance with this standard, the Company recognizes the compensation cost of each service-based award on a straight-line basis over the vesting period of such award. For the three and nine months ended April 30, 2015, the Company recorded stock-based compensation expense of approximately $1.8 million and $5.7 million respectively, in connection with its share-based awards. For the three and nine months ended April 30, 2014, the Company recorded stock-based compensation expense of approximately $1.3 million and $3.7 million respectively, in connection with its share-based awards.
Net income (loss) per share
Basic net income (loss) per common share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per common share reflects the maximum dilution that would have resulted from the assumed exercise and share repurchase related to dilutive stock options and RSUs, and is computed by dividing net income (loss) by the weighted average number of common shares and the dilutive effect of all securities outstanding.
Reconciliation between basic and diluted net income (loss) per common share is as follows:
	Three Months Ended						Nine Months Ended
	April 30,						April 30,
	2015			2014			2015			2014

For the three and nine months ended April 30, 2015 and 2014, options to purchase approximately 25,000 shares and 500,000 shares, respectively, of common stock were not included in the calculation of diluted net loss per share because the effect of including the options would have been anti-dilutive. These options could be dilutive in the future. The calculation of diluted net loss per share also excludes 2.2 million RSUs for the three and nine months ended April 30, 2014 in accordance with the contingently issuable shares guidance of Topic 260, Earnings Per Share, to the FASB ASC.
Cash and Cash Equivalents and Marketable Securities
The Company considers all highly liquid investments that are readily convertible to cash and that have original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of operating cash and money market accounts. Marketable securities consist primarily of debt securities that are classified as available-for-sale and held-to-maturity, in accordance with Topic 320, Investments—Debt and Equity Securities, to the FASB ASC. The Company also holds certain investments in commercial paper or certificates of deposit that it considers to be held-to-maturity, based on their respective maturity dates. Securities available-for-sale includes corporate, asset-backed, mortgage-backed, and governmental obligations with various contractual maturity dates, some of which are greater than one year. The Company considers the securities to be liquid and convertible to cash within 30 days. The Company has the ability and intent to liquidate any security that the Company holds to fund operations over the next twelve months, if necessary, and as such has classified all of its marketable securities as short-term. Governmental obligations include U.S. Government, State, Municipal and Federal Agency securities. The Company has an overnight sweep investment arrangement with its bank for certain accounts to allow the Company to enter into diversified overnight investments via a money market mutual fund which generally provides a higher investment yield than a regular operating account.

	Acquisition of Titan Semiconductor
	On February 2, 2015, the Company completed an acquisition of substantially all of the assets and certain specified liabilities of Titan. The purchase price of Titan was approximately $2.4 million, which was paid in cash from the Company’s available cash-on-hand. Titan develops, manufactures and sells products for semiconductor test serving the automotive, RF/Wireless, and mixed signal test markets. The acquired products will be developed, supported, and marketed by Xcerra’s Contactors operating segment which is part of the Semiconductor Test Solutions reportable segment. The Company has recorded approximately $1.3 million and $0.9 million of intangible assets and goodwill, respectively, from this transition.
	Acquisition of Everett Charles Technologies LLC and Multitest
	On September 6, 2013, in connection with the Dover Acquisition, the Company entered into a Master Sale and Purchase Agreement (the “Purchase Agreement”) with Dover and, solely for the limited purposes set forth in the Purchase Agreement, Dover Corporation (“Dover Parent”). Pursuant to the Purchase Agreement, the Company purchased from Dover or its specified affiliates (collectively, the “Sellers”) all assets of the Sellers used exclusively or primarily in connection with the research and development, design, manufacture, assembly, production, marketing, distribution, sale and repair of probes, assembled board and bare board test equipment, and fixturing products and the provision of services related thereto (the “ECT Business,” and such assets and intellectual property, the “ECT Assets”) and all assets of the Sellers used exclusively or primarily in connection with the research and development, design, manufacture, assembly, production, marketing, distribution, sale and repair of semiconductor test handlers, semiconductor test contactors and sockets and semiconductor test load boards, and the provision of services related thereto (the “MT Business,” and such assets and intellectual property, the “MT Assets”). The Company also assumed certain specified liabilities of the Sellers related primarily or exclusively to the Acquired Businesses or the Acquired Assets (as defined below). Under the Purchase Agreement, the Company also acquired all of the issued and outstanding capital stock and other equity interests of specified indirect subsidiaries of Dover Parent and its affiliates engaged in the Acquired Businesses, including Everett Charles Technologies LLC (such capital stock and other equity interests, the “Acquired Shares”). The ECT Assets, the MT Assets and the Acquired Shares are collectively referred to as the “Acquired Assets.”
	On December 1, 2013, the Company acquired the Multitest and ECT businesses of Dover for $93.5 million, of which $73.5 million was paid in cash through a combination of existing cash-on-hand and bank debt and $20.0 million was paid by the issuance of promissory notes. Pursuant to the Purchase Agreement, the cash purchase price was increased by $12.5 million to reflect, among other required adjustments, specified cash balances held by the Acquired Businesses, acquired indebtedness, certain transaction costs, employee related liabilities, working capital adjustments and reductions in the principal amount of the promissory notes payable to Dover in connection with the satisfaction of certain conditions.
	Subject to certain conditions, the original principal amount of the promissory notes is subject to reduction upon written certification from the Company to Dover prior to January 1, 2015 of certain specified events related to the Company’s relocation from or refurbishment of certain properties of the Acquired Businesses, or the prepayment of the promissory notes in full prior to such date. In January 2014, the Company executed leases for two new facilities, and in February 2014, the Company provided Dover with written certification of a planned relocation from certain properties of the Acquired Businesses. Consequently, the original principal amount of the promissory notes issued to Dover was reduced by $2.0 million. The promissory notes were subject to further reduction by $1.75 million upon certification from the company to Dover of other specified events that had not yet occurred. The promissory notes were to accrue interest on the unpaid balance for each day that they remained outstanding after December 1, 2014 at a per annum rate equal to the London Interbank Offered Rate plus 10%, and could be prepaid by the Company at any time without penalty prior to May 1, 2019. After giving effect to the post-Closing purchase price adjustments described above, and including the principal amount reduction of the promissory notes to Dover, the aggregate purchase price paid to the Sellers as of the date of this report is $106.0 million.
	In November 2014, the Company prepaid the outstanding amounts under the promissory notes. The $16.25 million payoff amount reflected the principal amounts of $18.0 million that was outstanding under the original promissory notes, less a $1.75 million reduction triggered by the prepayment in full of the notes prior to January 1, 2015.
	The Company, Dover, and certain of their affiliates, also entered into a transition services agreement, an intellectual property termination agreement and a license agreement which govern certain ongoing relationships between the Company and Dover and their respective affiliates following the Closing.
	In accordance with Topic 805, Business Combinations, to the FASB ASC and based on the terms of the Dover Acquisition, the Company is the accounting acquirer.
	The following is a summary of the purchase price for the Acquired Assets:
		(in thousands)
	Cash paid for Acquired Assets	$	88,009
	Seller financing – Dover promissory notes		18,000
	Purchase price	$	106,009
	The following table summarizes the amounts recognized for the Acquired Assets and liabilities assumed as of the date of Closing.
	The purchase price has been allocated based on the fair value of net assets acquired as follows:
		(in thousands)
	Allocation of purchase consideration
	Fair value of assets acquired as of December 1, 2013:
	Cash	$	18,024
	Accounts receivable		51,069
	Inventory		41,642
	Property, plant and equipment		22,859
	Identifiable intangible assets		12,000
	Other assets		3,410
	Assets acquired:	$	149,004
	Fair value of liabilities acquired:
	Liabilities		(32,260	)
	Deferred taxes		(2,114	)
	Adjusted net assets acquired	$	114,630
	Purchase price		(106,009	)
	Bargain purchase gain	$	8,621
	The overall fair value of the net assets acquired by the Company exceeded the amount paid, which resulted in the recognition of a bargain purchase gain by the Company during the fiscal year ended July 31, 2014 (fiscal 2014). This bargain purchase gain was recorded as a component of the other income (expense) section on the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss). The Company believes it was able to acquire ECT and Multitest for less than the fair value of their net assets since ECT and Multitest had been held as discontinued operations by Dover for more than one year.
	Valuation of Intangible Assets and Goodwill
	The overall fair value of the Multitest and ECT businesses of Dover has been allocated to tangible assets acquired, assumed liabilities, and identifiable intangible assets, based upon a detailed valuation that uses information and assumptions provided by management, as further described below.
	Identifiable Intangible Assets
	As part of the purchase price allocation, identifiable intangible assets of the Acquired Businesses include developed technology, customer relationships and trademarks.
	The consolidated financial statements include estimated identifiable intangible assets with a fair value at acquisition of $12.0 million, which are being amortized based on the pattern and period over which the economic benefits of the intangible assets are realized. The current estimated weighted average period is 6.9 years. The Company engaged independent valuation advisors to assist the Company in estimating the identifiable intangible asset value. The estimated identifiable intangible asset value was primarily based on information and assumptions developed by the Company’s management, certain publicly available information, and discussions with management of the Acquired Businesses.
	The Company used the income approach to value the developed technology and other acquired identifiable intangible assets of the Acquired Businesses. This approach calculates fair value by estimating future cash flows attributable to each intangible asset and discounting the future cash flows to present value using a risk adjusted discount rate.
	In estimating the useful life of the acquired intangible assets of the Acquired Businesses, the Company considered paragraph 11 of FASB ASC 350, which lists the pertinent factors to be considered when estimating the useful life of an intangible asset. These factors include a review of the expected use by the combined company of the assets acquired, the expected useful life of another asset (or group of assets) related to the acquired assets, legal, regulatory or other contractual provisions that may limit the useful life of an acquired asset or may enable the extension of the useful life of an acquired asset without substantial cost, the effects of obsolescence, demand, competition and other economic factors, and the level of maintenance expenditures required to obtain the expected future cash flows from the asset. The Company is amortizing these intangible assets over their estimated useful lives using a method that is based on estimated future cash flows as the Company believes this amortization methodology approximates the pattern in which the economic benefits of the intangible assets will be derived.
	The identifiable intangible assets associated with the Dover Acquisition include $6.7 million of trademarks. The Company believes these trademarks will contribute to the Company’s cash flows indefinitely. Therefore, in accordance with ASC 350, the Company has assigned an indefinite useful life to the trademarks, and will not amortize the trademarks until their useful lives are no longer indefinite.
	Supplemental Pro-Forma Information
	The following unaudited pro-forma information presents the consolidated results of operations of the Company, and the Acquired Businesses, as if the Dover Acquisition had occurred as of August 1, 2014, with pro-forma adjustments to give effect to amortization of intangible assets and certain other adjustments (in thousands):
		Nine Months Ended

		Actual			Pro-forma
	Net sales	$	323,089		$	297,221
	Net income (loss)	$	20,730		$	(12,747	)
	The unaudited pro forma net loss for the nine months ended April 30, 2014 includes $3.6 million of charges related to the Dover Acquisition for restructuring costs and approximately $0.6 million of acquisition costs, which were incurred after December 1, 2013. The unaudited pro forma results are not necessarily indicative of the results that the Company would have attained had the Dover Acquisition occurred at the beginning of the periods presented. The Company has included the actual results for the periods ended April 30, 2015 for comparative purposes.

Segment Reporting and Geographic Information	4. SEGMENT REPORTING AND GEOGRAPHIC INFORMATION
	Segment Reporting
	In accordance with the provisions of Topic 280, Segment Reporting (“ASC 280”), starting in fiscal 2014, the Company determined that it has seven operating segments (Semiconductor Test, Semiconductor Handlers, Contactors, Interface Boards, PCB Test, Probes / Pins, and Fixtures). Based on the aggregation criteria of ASC 280, the Company determined that several of the operating segments can be aggregated due to these segments having similar economic characteristics and meeting all of the other aggregation criteria in ASC 280. Consequently, the Company has two reportable segments: the Semiconductor Test Solutions (STS) reportable segment, which is comprised of the Semiconductor Test, Semiconductor Handlers, Contactors, and Interface Boards operating segments, and the Electronic Manufacturing Solutions (EMS) reportable segment, which is comprised of the PCB Test, Probes / Pins and Fixtures operating segments. This financial reporting structure was implemented effective as of December 1, 2013, the acquisition date of Multitest and ECT.
	The Semiconductor Test operating segment includes operations related to the design, manufacture and sale of automated test equipment for the semiconductor industry that is used to test system-on-a-chip, digital, analog and mixed signal integrated circuits. The Semiconductor Handlers operating segment includes operations related to the design, manufacture and sale of test handlers used in the testing of integrated circuits. The Contactors segment includes operations related to the design, manufacture and sale of test contactors which serve as the interface between the test handler and the semiconductor device under test. The Interface Boards operating segment includes operations related to the design, manufacture and sale of circuit boards designed to serve as an interface between the tester and the semiconductor device under test. The PCB test operating segment includes operations related to design, manufacture and sale of equipment used in the testing of bare and loaded printed circuit boards. The Probes / Pins operating segment includes operations related to the design, manufacture and sale of the physical devices used to connect electronic test equipment to the device under test. The Fixtures segment includes operations related to the design, manufacture and sale of PCB test fixtures that enable the transmission of test signals from the loaded PCB to the tester. Each operating segment has a segment manager who is directly accountable to and maintains regular contact with the Company’s chief operating decision maker (chief executive officer and chief operating officer) to discuss operating activities, financial results, forecasts, and plans for the segment.
	The Company evaluates performance using several factors, of which the primary financial measures are revenue and operating segment operating income. The accounting policies of the operating segments are the same as those described in Note 2 “Summary of Significant Accounting Policies”.

Restructuring	5. RESTRUCTURING
	In accordance with the provisions of Topic 420, Exit or Disposal Cost Obligation, the Company recognizes certain costs associated with headcount reductions, office vacancies and other costs to move or relocate operations or employees as restructuring costs in the period in which such actions are initiated and approved by management or the obligations are incurred, as applicable.
	During the three months ended April 30, 2015, the Company announced plans to reorganize certain parts of its Fixtures segment. As a result, the Company will close three facilities worldwide (two in the United States and one in Singapore) and reduce headcount in those locations. In connection with these plans, the Company incurred costs of approximately $0.5 million during the three months ended April 30, 2015.
	As of April 30, 2015, the Company’s restructuring accrual also included obligations related to remaining lease and property tax payments associated with the Company’s decision to vacate facilities during the fiscal years ended July 31, 2014 and 2009, as well as severance obligations payable related to headcount reductions from actions undertaken during fiscal 2014 and the nine months ended April 30, 2015.
	During the nine months ended April 30, 2015, the Company relocated to other offices in certain jurisdictions, and incurred approximately $0.5 million in relocation costs, which were included in restructuring expense for the period. The remainder of the expense incurred during the nine months ended April 30, 2015 of $1.0 million was related to severance and other post- employment obligations for certain headcount reductions implemented during the period.

Commitments and Contingencies	9 Months Ended
	Apr. 30, 2015
Commitments and Contingencies	6. COMMITMENTS AND CONTINGENCIES
	From time to time, the Company is subject to certain legal proceedings and other contingencies, the outcomes of which are subject to significant uncertainty. The Company accrues for estimated losses if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. The Company uses judgment and evaluates, with the assistance of legal counsel, whether a loss contingency arising from litigation should be disclosed or recorded. The outcome of legal proceedings and other contingencies is inherently uncertain and often difficult to estimate. Accordingly, if the outcome of legal proceedings and other contingencies is different than is anticipated by the Company, the Company would record the difference between any previously recorded amount and the full amount at which the matter was resolved, in earnings in the period resolved, which could negatively impact the Company’s results of operations and financial position for the period.
	The Company is a defendant in a litigation matter incidental to the business that is related to customer expectations of test system performance for products that were shipped in 2006 by Credence. The Company does not believe the plaintiff’s claims have merit and is vigorously defending its position. An estimate of any potential loss cannot be made, and accordingly the Company has not accrued any amounts related to this matter.
	In the ordinary course of business, the Company agrees from time to time to indemnify certain customers against certain third party claims for property damage, bodily injury, personal injury or intellectual property infringement arising from the operation or use of the Company’s products. Also, from time to time in agreements with suppliers, licensors, and other business partners, the Company agrees to indemnify these partners against certain liabilities arising out of the sale or use of the Company’s products. The maximum potential amount of future payments the Company could be required to make under these indemnification obligations is theoretically unlimited; however, the Company has general and umbrella insurance policies that enable it to recover a portion of any amounts paid, and many of its agreements contain a limit on the maximum amount, as well as limits on the types of damages recoverable. Based on the Company’s experience with such indemnification claims, it believes the estimated fair value of these obligations is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of April 30, 2015 or July 31, 2014.
	Subject to certain limitations, the Company indemnifies its current and former officers and directors for liability or costs that may incur in certain circumstances in connection with their services as directors and officers of the Company. Although the maximum potential amount of future payments the Company could be required to make under these agreements is theoretically unlimited, as there were no known or pending claims, the Company has not accrued a liability for these agreements as of April 30, 2015 or July 31, 2014.
	As of April 30, 2015, the Company had approximately $43.7 million of non-cancelable inventory commitments with its suppliers. The Company expects to consume this inventory through normal operating activity.
	The Company has operating lease commitments for certain facilities and equipment that expire at various dates through 2024. The Company has an option to extend the term for its Norwood, Massachusetts facility lease for a single extension term of five years provided that the Company notifies its landlord at least 425 days prior to expiration of the current extension term. Minimum lease payment obligations under non-cancelable leases as of April 30, 2015, are as follows:

	Credit Agreement
	On December 15, 2014, the Company entered into a credit agreement (the “ Credit Agreement”) with Everett Charles Technologies LLC, a wholly owned subsidiary of the Company (“ECT” and together with the Company, the “Borrowers”), Silicon Valley Bank, as lender, administrative agent and issuing lender (“SVB”), and the several lenders from time to time party thereto (the “Lenders”). The Credit Agreement provides for a senior secured credit facility, consisting of a term loan facility (the “Term Loan”), in favor of the Borrowers in the aggregate principal amount of $25.0 million which was advanced to the Company on December 15, 2014 (the “Facility”).
	The proceeds of the Term Loan were used to pay off $25.0 million of the outstanding indebtedness under the previous credit facility that was advanced to the Company pursuant to that certain credit agreement entered into on November 27, 2013 with ECT, SVB as lender, administrative agent and issuing lender, and the lenders from time to time party thereto (the “Original Credit Agreement”). As of December 15, 2014, no amounts remained outstanding under the credit facility issued under the Original Credit Agreement.
	All obligations under the Facility are secured by a first priority security interest in substantially all of the Borrowers’ existing and future assets, including a pledge of the stock or other equity interests of the Borrowers’ domestic subsidiaries and of any first tier foreign subsidiaries, provided that not more than 66% of the voting stock of any such foreign subsidiaries shall be required to be pledged.
	The Credit Agreement requires that the Term Loan be repaid in quarterly installments, with 5% of the principal due the first year, 10% of principal due in each of the second and third years, 15% of principal due the fourth year, and a final payment of $15 million due on December 14, 2018 (the “Maturity Date”). The outstanding balance of the Term Loan may, at the Borrowers’ option, be prepaid at any time in whole or in part without premium or penalty, other than customary breakage costs, if any, subject to the terms and conditions of the Credit Agreement.
	As the terms of the Credit Agreement were not substantially different from the terms of the Original Credit Agreement, the Company accounted for this transaction as a modification of debt, and accordingly continues to recognize deferred financing fees over the term of the Credit Agreement.
	Borrowings made under the Facility bear interest, at a base rate plus a margin (such margin not to exceed a per annum rate of 1.75%) based on a ratio of the Company’s consolidated senior debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) (the “Leverage Ratio”), or at a LIBOR rate plus a margin (such margin not to exceed a per annum rate of 2.75%) based on the Leverage Ratio. The interest rate otherwise payable under the Facility will be subject to increase by 2.0% per annum during the continuance of a payment default and may be subject to increase by 2.0% per annum during the continuance of any other event of default. As of April 30, 2015, the interest rate in effect on the Facility was 2.63%.
	Covenants
	The Credit Agreement contains customary affirmative and negative covenants, subject in certain cases to baskets and exceptions, including negative covenants with respect to indebtedness, liens, fundamental changes, dispositions, restricted payments, investments, ERISA matters, matters relating to subordinated debt, affiliate transactions, sale and leaseback transactions, swap agreements, accounting changes, negative pledge clauses, clauses restricting subsidiary distributions, lines of business, amendments to certain documents and use of proceeds. The Credit Agreement also contains customary reporting and other affirmative covenants. The Credit Agreement contains a consolidated fixed charge coverage ratio and consolidated leverage ratio.
	The Company’s obligations under the Facility may be accelerated upon the occurrence of an event of default under the Credit Agreement, which includes customary events of default, including payment defaults, the inaccuracy of representations or warranties, the failure to comply with covenants, ERISA defaults, judgment defaults, bankruptcy and insolvency defaults and cross defaults to material indebtedness
	As of April 30, 2015, the Company was in compliance with all covenants under the Credit Agreement.
	Seller Financing – Promissory Notes
	As described in Note 3 above, pursuant to the Purchase Agreement, in connection with the closing of the Dover Acquisition, the Company issued promissory notes having an aggregate principal amount of $20.0 million to Dover. During the three months ended January 31, 2014, the original principal amount of the promissory notes issued to Dover was reduced by $2.0 million, when the company executed leases for two new facilities, which triggered a reduction to the notes in accordance with the provisions of the notes. On November 26, 2014, the Company repaid in full all outstanding amounts under these promissory notes. The $16.25 million payoff amount reflected the principal amount of $18.0 million that was outstanding under the original promissory notes, less $1.75 million pursuant to a reduction in principal for which the Company was entitled under the original promissory notes. Such reduction related to prepayment of the promissory notes before January 1, 2015 and was recorded as a gain on repayment of subordinated debt as a component of other income in the nine months ended April 30, 2015 in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss). As a result of this repayment during the interest-free period, the Company reversed approximately $0.9 million of accrued interest and recorded the benefit as a component of other income in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) for the nine months ended April 30, 2015.

Fair_Value_Measurements

Fair Value Measurements	9 Months Ended

Fair Value Measurements	9. FAIR VALUE MEASUREMENTS
	The Company determines its fair value measurements for assets and liabilities based upon the provisions of Topic 820, Fair Value Measurements and Disclosures to the FASB ASC.
	The Company holds short-term money market investments and certain other financial instruments which are carried at fair value. The Company determines fair value based upon quoted prices, when available or through the use of alternative approaches when market quotes are not readily accessible or available.
	Valuation techniques for fair value are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s best estimate, considering all relevant information. These valuation techniques involve some level of management estimation and judgment. The valuation process to determine fair value also includes making appropriate adjustments to the valuation model outputs to consider risk factors.
	The fair value hierarchy of the Company’s inputs used in the determination of fair value for assets and liabilities during the current period consists of three levels. Level 1 inputs are composed of unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 inputs include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 inputs incorporate the Company’s own best estimate of what market participants would use in pricing the asset or liability at the measurement date where consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. If inputs used to measure an asset or liability fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the asset or liability. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability.
	The following table presents financial assets and liabilities measured at fair value and their related valuation inputs as of April 30, 2015 and July 31, 2014:
					Fair Value Measurements at Reporting Date Using
					(in thousands)

	-1	Cash and cash equivalents as of April 30, 2015 and July 31, 2014 included cash held in operating accounts of approximately $71.5 million and $56.0 million, respectively that are not subject to fair value measurements. For purposes of this disclosure, they are included as having level 1 inputs.
	The carrying value of accounts receivable, prepaid expenses, accounts payable, and accrued expenses approximate fair value due to their short-term nature.
	There were no assets or liabilities not measured at fair value but for which fair value is required to be disclosed. The carrying value of the Company’s long-term debt, which includes term loans (and seller-financed promissory notes for the period ended July 31, 2014) approximates fair value due to market interest. Long-term debt as of April 30, 2015 and July 31, 2014 was $26.8 million and $68.7 million, respectively. Within the hierarchy of fair value measurement, these are level 2 inputs.

Stockholders' Equity	10. STOCKHOLDERS’ EQUITY
	Equity Offering
	On September 17, 2014, the Company closed an underwritten public offering of 4,682,927 shares of its common stock at $10.25 per share. The Company also granted to the underwriters a 30-day option to purchase up to an aggregate of 702,439 additional shares of common stock to cover over-allotments which they exercised on September 22, 2014. All of the shares were sold by the Company pursuant to an effective shelf registration statement previously filed with the U.S. Securities and Exchange Commission.
	The offering, and the follow-on option to sell additional shares, resulted in net proceeds to Xcerra, after deducting underwriting discounts and commissions and offering expenses, of approximately $52.1 million. Xcerra used approximately $24.0 million of the net proceeds from the offering to repay a portion of the outstanding principal of Term Loan. The Company also used $16.3 million of the proceeds to repay promissory notes issued by Dover.
	Stock Repurchases
	On September 15, 2011, the Company announced that its Board of Directors had authorized a stock repurchase program for up to $25 million of shares of the Company’s common stock. Under this program, the Company is authorized to repurchase shares of its common stock from time to time in open market transactions. The Company will determine the timing and amount of the transactions based on its evaluation of market conditions and other factors. The repurchase program may be suspended or discontinued at any time and has no expiration date. During the three and nine months ended April 30, 2015 and the three and nine months ended April 30, 2014, the Company did not repurchase any shares under this program. Cumulatively, as of April 30, 2015, the Company has repurchased 3,294,666 shares of common stock for a total purchase price of $18.7 million since the inception of the program.

Recent Accounting Pronouncements	11. RECENT ACCOUNTING PRONOUNCEMENTS
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“Topic 606”), which will replace numerous requirements in GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. For Xcerra, the standard will be effective for the fiscal year starting August 1, 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company has not yet selected a transition method. The Company is currently evaluating the impact of this ASU on its financial position and results of operations.
	In April 2015, the FASB issued ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard takes effect for public companies for financial statements issued for fiscal years beginning after Dec. 15, 2015, and interim periods within those fiscal years. For private companies and not-for-profit organizations, the standard takes effect for fiscal years beginning after Dec. 15, 2015, and interim periods within fiscal years beginning after Dec. 15, 2016. Early adoption is permitted. The Company does not expect the adoption of this update to have a material impact on its financial position and results of operation.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Apr. 30, 2015
Basis of Presentation	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). These footnotes condense or omit information and disclosures which substantially duplicate information provided in the Company’s latest audited financial statements. These unaudited consolidated financial statements should be read in conjunction with the financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments, including normal recurring accruals, necessary for a fair presentation of the results for the interim periods presented. The operating results for the three and nine months ended April 30, 2015 are not necessarily indicative of future trends or the Company’s results of operations for the entire fiscal year ending July 31, 2015.
	Certain prior period amounts on the balance sheet have been reclassified to conform to the current period presentation. Net income and shareholders’ equity were not affected by these reclassifications. The Company’s Consolidated Statements of Operations and Comprehensive Income (Loss) and Statements of Cash Flows for the three and nine months ended April 30, 2014 also reflect retroactive adjustments made by the Company to the bargain purchase gain reported as part of the Company’s acquisition of the ECT and Multitest businesses, which was reported in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014.
	The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation.
Revenue Recognition	Revenue Recognition
	The Company recognizes revenue based on guidance provided in Topic 605, Revenue Recognition, to the Financial Accounting Standards Board Codification (“FASB ASC”) and Accounting Standards Update 2009-13, Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price is fixed or determinable and collectability is reasonably assured.
	Revenue related to equipment sales is recognized when: (a) the Company has a written sales agreement; (b) delivery has occurred or service has been rendered; (c) the price is fixed or determinable; (d) collectability is reasonably assured; (e) the equipment delivered is a standard product with historically demonstrated acceptance; and (f) there is no unique customer acceptance provision or payment tied to acceptance or an undelivered element significant to the functionality of the system. Generally, payment terms are time based after product shipment. From time to time, sales to a customer may involve multiple elements, in which case revenue is recognized on the delivered element provided that (1) the undelivered element is a proven technology, (2) there is a history of acceptance on the equipment with the customer, (3) the undelivered element is not essential to the customer’s application, (4) the delivered item(s) has value to the customer on a stand-alone basis, and (5) if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The arrangement consideration, or the amount of revenue to be recognized on each separate unit of accounting, is allocated at the inception of the arrangement to all deliverables on the basis of their relative selling price.
	Revenue related to maintenance and service contracts is recognized ratably over the duration of the contracts. Net service sales as presented in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) includes revenue associated with LTX-Credence maintenance or service contracts only, and excludes ECT and Multitest. ECT and Multitest generally do not provide maintenance and service contracts, but rather sell spare parts and other components, and as a result these sales are recognized as net product sales in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss). Revenue related to spare parts and components is recognized when the four main criteria listed above are met. Generally customer acceptance is not required for spare parts and component sales.
Inventories	Inventories
	Inventories are stated at the lower of cost or market, determined on the first-in, first-out (“FIFO”) method, and include materials, labor and manufacturing overhead. The components of inventories are as follows:
		April 30,			July 31,
		2015			2014
		(in thousands)
	Material and purchased components	$	23,983		$	22,394
	Work-in-process		24,157			23,806
	Finished equipment, including inventory consigned to customers		15,632			23,470
	Total inventories	$	63,772		$	69,670
	The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market conditions. The Company regularly evaluates its ability to realize the value of inventory based on a combination of factors, including forecasted sales or usage, estimated product end of life dates, estimated current and future market value, and new product introductions.
	Purchasing and usage alternatives are also explored to mitigate inventory exposure. When recorded, reserves are intended to reduce the carrying value of inventory to its net realizable value. As of April 30, 2015 and July 31, 2014, inventory was stated net of inventory reserves of $48.0 million and $45.3 million, respectively. If actual demand for products deteriorates or market conditions are less favorable than projected, additional inventory reserves may be required. Such reserves are not reversed until the related inventory is sold or otherwise disposed of.
Goodwill and Other Intangibles	Goodwill and Other Intangibles
	In accordance with FASB ASC Topic 350—Intangibles—Goodwill and Other (“ASC 350”), goodwill is not amortized. Rather, the Company’s goodwill is subject to periodic impairment testing. ASC 350 requires that the Company assign its goodwill to reporting units and test each reporting unit’s goodwill for impairment at least on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.
	The testing of goodwill for impairment is performed at a level referred to as a reporting unit. As of April 30, 2015, the Company currently has one reporting unit to which the full balance of goodwill is allocated, its semiconductor test reporting unit. Based on ASC 350-20-35-3A, as of April 30, 2015, there were no triggering events that required the Company to complete impairment testing.
	The Company’s goodwill consists of the following:
	Goodwill	April 30,			July 31,

	Total intangible assets				$	32,600		$	(27,735	)	$	4,865
	Intangible assets, other than trademarks owned by the Company, are amortized based upon the pattern of estimated economic use over their estimated useful lives. The weighted average estimated remaining useful life over which these intangible assets will be amortized is 4.7 years.
	The Company expects the remaining amortization for these intangible asset as of April 30, 2015 to be:
	Year ending July 31,	Amount
		(in thousands)
	2015	$	450
	2016		1,243
	2017		688
	2018		487
	Thereafter		1,829
	Total	$	4,697
	The identifiable intangible assets associated with the Dover Acquisition include $6.7 million of trademarks. The Company believes these trademarks will contribute to the Company’s cash flows indefinitely. Therefore, in accordance with ASC 350, the Company has assigned an indefinite useful life to the trademarks, and will not amortize the trademarks until their useful lives are no longer indefinite.
Long Lived Assets	Long Lived Assets
	On an on-going basis, management reviews the value of and period of amortization or depreciation of the Company’s long-lived assets. In accordance with Topic 360, Property, Plant and Equipment, to the FASB ASC, the Company reviews whether impairment losses exist on its long-lived assets other than goodwill when indicators of impairment are present. During this review, the Company assesses future cash flows and re-evaluates the significant assumptions used in determining the original cost of long-lived assets other than goodwill. Although the assumptions may vary, they generally include revenue growth, operating results, cash flows and other indicators of value. Management then determines whether there has been a permanent impairment of the value of long-lived assets based upon events or circumstances that have occurred since acquisition. The impairment amount recognized is based upon a determination of the impaired asset’s fair value compared to its carrying value. As of April 30, 2015, there were no indicators that required the Company to conduct a recoverability test.
Foreign Currency Remeasurement	Foreign Currency Remeasurement
	The financial statements of the Company’s foreign subsidiaries are remeasured in accordance with Topic 830, Foreign Currency Matters, to the FASB ASC. The functional currency of the Company’s tester group is the U.S. dollar. Accordingly, the Company’s foreign subsidiaries that are included in this group remeasure monetary assets and liabilities at month-end exchange rates while long-term non-monetary items are remeasured at historical rates. Income and expense accounts are remeasured at the average rates in effect during the month. Net gains (losses) resulting from foreign currency remeasurement and transaction gains (losses) are included in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss) as a component of other income, net, and were $(0.1) million and $(1.8) million, respectively for the three and nine months ended April 30, 2015 and $(0.3) million and $0.4 million, respectively for the three and nine months ended April 30, 2014. The functional currency of each of the Acquired Businesses is the local currency, predominantly Euro, Malaysian Ringgit and Singapore Dollars, and net gains or losses resulting from foreign currency remeasurement and translation gains or losses are recorded in stockholders’ equity as accumulated other comprehensive income (loss).

	Certain of the Company’s products are sold with warranty provisions that require it to remedy deficiencies in quality or performance of products over a specified period of time at no cost to its customers. The Company generally offers a warranty for most of its products, the standard terms and conditions of which are based on the product sold and the customer. For all products sold, subject to a warranty, the Company accrues a liability for the estimated cost of standard warranty at the time of shipment. Factors that impact the warranty liability include the number of installed products, historical and anticipated product failure rates, material usage and service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts such amounts as necessary.
	The following table shows the change in the Company’s product warranty liability, as required by Topic 460, Guarantees, to the FASB ASC for the nine months ended April 30, 2015 and 2014:
		Nine Months Ended
		April 30,
	Product Warranty Activity	2015			2014

Engineering and Product Development Expenses	Engineering and Product Development Expenses
	The Company expenses all engineering and product development expenses as incurred. Expenses relating to certain software development costs, which were subject to capitalization in accordance with Topic 485, Software, to the FASB ASC, were insignificant.
Shipping and Handling Costs	Shipping and Handling Costs
	Shipping and handling costs are included in cost of sales in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss). Shipping and handling costs were insignificant for the three and nine months ended April 30, 2015 and 2014.
Income Taxes	Income Taxes
	Provision for income taxes relates principally to operating results of profitable foreign entities in jurisdictions primarily in Asia and Europe partially offset by a tax benefit recorded as a result of the Dover Acquisition, and the release of reserves due to statute of limitation expirations.
	As of April 30, 2015 and July 31, 2014, the Company’s total liability for unrecognized income tax benefits was $5.9 million and $6.6 million, respectively (of which $2.3 million and $3.0 million, respectively, if recognized, would impact the Company’s income tax rate). The Company recognizes interest and penalties related to uncertain tax positions as a component of provision for income taxes. As of April 30, 2015 and July 31, 2014, the Company had accrued approximately $0.9 million and $1.0 million, respectively, for potential payment of accrued interest and penalties.
	The Company conducts business globally and, as a result, the Company and its subsidiaries or branches file income tax returns in the U.S. federal jurisdiction and various U.S. state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as the United States, Singapore, Malaysia, China, France and Germany. With few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations for the years prior to 1998.
	As a result of the Company’s merger with Credence on August 29, 2008, a greater than 50% cumulative ownership change in both entities triggered a significant limitation on net operating loss carryforward utilization. The Company’s ability to use acquired U.S. net operating loss and credit carryforwards is subject to annual limitation as defined in sections 382 and 383 of the Internal Revenue Code. The Company currently estimates that the annual limitation on its use of net operating losses generated through August 29, 2008 will be approximately $10.1 million which, based on currently enacted federal carryforward periods, limits the amount of net operating losses that are available for utilization to approximately $202.0 million. The Company has recorded a valuation allowance against the full value of U.S. net operating loss and credit carryforwards, and will continue to assess the realizability of these carryforwards in subsequent periods.
Accounting for Stock-Based Compensation	Accounting for Stock-Based Compensation
	The Company has equity awards outstanding under various stock-based compensation plans, including the 2010 Stock Plan (“2010 Plan”), 2004 Stock Plan, 2001 Stock Plan, 1999 Stock Plan, and 1993 Stock Plan. In addition, the Company assumed the Credence 2005 Stock Incentive Plan in connection with its acquisition of Credence. The Company can only grant awards from the 2010 Plan.
	During the three months ended April 30, 2015, the Company granted 112,167 Restricted Stock Units (“RSUs”), all of which are service-based and vest 25% per year for four years. The stock-based compensation expense related to these awards is recognized over their vesting periods.
	The Company recognizes stock-based compensation expense on its equity awards in accordance with the provisions of Topic 718, Compensation—Stock Compensation to the FASB ASC (“Topic 718”). Under Topic 718, the Company is required to recognize as expense the estimated fair value as of the grant date of all share-based awards to employees. In accordance with this standard, the Company recognizes the compensation cost of each service-based award on a straight-line basis over the vesting period of such award. For the three and nine months ended April 30, 2015, the Company recorded stock-based compensation expense of approximately $1.8 million and $5.7 million respectively, in connection with its share-based awards. For the three and nine months ended April 30, 2014, the Company recorded stock-based compensation expense of approximately $1.3 million and $3.7 million respectively, in connection with its share-based awards.
Net income (loss) per Share	Net income (loss) per share
	Basic net income (loss) per common share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per common share reflects the maximum dilution that would have resulted from the assumed exercise and share repurchase related to dilutive stock options and RSUs, and is computed by dividing net income (loss) by the weighted average number of common shares and the dilutive effect of all securities outstanding.
	Reconciliation between basic and diluted net income (loss) per common share is as follows:
		Three Months Ended						Nine Months Ended
		April 30,						April 30,
		2015			2014			2015			2014
		(in thousands, except per share data)

	Basic income (loss) per share	$	0.09		$	(0.00	)	$	0.39		$	(0.18	)
	Diluted EPS:

	Plus: impact of stock options and unvested RSUs		583			—			810			—
	Weighted average shares outstanding- diluted		55,131			48,356			54,143			48,156
	Diluted income (loss) per share	$	0.09		$	(0.00	)	$	0.38		$	(0.18	)
	For the three and nine months ended April 30, 2015 and 2014, options to purchase approximately 25,000 shares and 500,000 shares, respectively, of common stock were not included in the calculation of diluted net loss per share because the effect of including the options would have been anti-dilutive. These options could be dilutive in the future. The calculation of diluted net loss per share also excludes 2.2 million RSUs for the three and nine months ended April 30, 2014 in accordance with the contingently issuable shares guidance of Topic 260, Earnings Per Share, to the FASB ASC.
Cash and Cash Equivalents and Marketable Securities	Cash and Cash Equivalents and Marketable Securities
	The Company considers all highly liquid investments that are readily convertible to cash and that have original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of operating cash and money market accounts. Marketable securities consist primarily of debt securities that are classified as available-for-sale and held-to-maturity, in accordance with Topic 320, Investments—Debt and Equity Securities, to the FASB ASC. The Company also holds certain investments in commercial paper or certificates of deposit that it considers to be held-to-maturity, based on their respective maturity dates. Securities available-for-sale includes corporate, asset-backed, mortgage-backed, and governmental obligations with various contractual maturity dates, some of which are greater than one year. The Company considers the securities to be liquid and convertible to cash within 30 days. The Company has the ability and intent to liquidate any security that the Company holds to fund operations over the next twelve months, if necessary, and as such has classified all of its marketable securities as short-term. Governmental obligations include U.S. Government, State, Municipal and Federal Agency securities. The Company has an overnight sweep investment arrangement with its bank for certain accounts to allow the Company to enter into diversified overnight investments via a money market mutual fund which generally provides a higher investment yield than a regular operating account.
