Summary of Significant Accounting Policies	'
	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The 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.
	Preparation of Financial Statements and Use of Estimates
	The accompanying financial statements have been prepared by the Company, and reflect all adjustments, which, in the opinion of management, are necessary for fair presentation. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the reporting periods. Actual results may differ from those estimates and such differences may be material to the consolidated financial statements. Such estimates relate to fair values ascribed to the assets and liabilities acquired in connection with the Dover Acquisition, revenue recognition, the allowance for doubtful accounts, inventory valuation, depreciation, product warranty costs, stock-based compensation and income taxes, among others.
	Revenue Recognition
	The Company recognizes revenue based on guidance provided in Topic 605, Revenue Recognition, to the FASB ASC (“ASC 605”) and Accounting Standards Update (“ASU”) 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 product 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 product 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 included 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 spare parts is recognized on shipment.
	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 and service contracts only and excludes ECT and Multitest. These businesses generally do not provide maintenance or 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 Results of Operations.
	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:
			As of July 31,
			2014			2013
			(in thousands)
	Material and purchased components		$	22,394		$	15,379
	Work-in-process			23,806			2,887
	Finished equipment, including inventory consigned to customers			23,470			10,873
	Total inventories		$	69,670		$	29,139
	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 the following: 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 July 31, 2014 and July 31, 2013, inventory is stated net of inventory reserves of $45.3 million and $41.8 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.
	The following table shows sales of previously reserved inventory and the inventory reserves released for these sales for the fiscal years ended 2014, 2013, and 2012:
			Fiscal Year Ended July 31,
			2014			2013			2012
			(in thousands)
	Sales of previously reserved inventory		$	821		$	869		$	6,859
	Inventory reserves released for these sales			483			300			2,035
	Goodwill and Other Intangibles
	In accordance with 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 July 31, 2014, the Company currently has one reporting unit to which the full balance of goodwill is allocated, its Semiconductor Test group. All of the goodwill recorded on the Company’s Consolidated Balance Sheet is related to its LTX-Credence business, since the Company did not change the underlying reporting structure of the Semiconductor Test reporting unit. Based on ASC 350-20-35-3A, as of July 31, 2014, the Company assessed qualitative factors to determine whether the two-step goodwill impairment test is necessary. Since the Company determined, based on the qualitative assessment, that it is more likely than not that its reporting unit’s fair value is greater than its carrying amount, no further impairment testing was required and no adjustment to the carrying amount of goodwill was necessary.
	The Company’s goodwill consists of the following:
	Goodwill		July 31,			July 31,
			2014			2013
			(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
	Total goodwill		$	43,030		$	43,030
	Amortizable intangible assets which relate to the acquisition of the ECT and Multitest businesses and the Credence merger, consist of the following, and are included in intangible assets, net on the Company’s Consolidated Balance Sheets:
						As of July 31, 2014
						(in thousands)

	Maintenance agreements—ASL and Diamond			7			1,900			1,086			814
	Total intangible assets					$	27,300		$	25,729		$	1,571
	Intangible assets 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 4.3 years.
	The Company expects amortization for these intangible assets to be:
	Year ending July 31,		Amount
(in thousands)
2015		$	1,892
2016			1,171
2017			617
2018			414
Thereafter			771
Total		$	4,865
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.
Impairment of Long-Lived Assets Other Than Goodwill
On an ongoing 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 July 31, 2014 and July 31, 2013, there were no indicators that required the Company to conduct a recoverability test as of those dates.
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 or losses resulting from foreign currency remeasurement and transaction gains or losses are included in the consolidated results of operations as a component of other expense, net, and were not significant for the fiscal years ended July 31, 2014, 2013 and 2012. The functional currency of each of the Acquired Businesses is local currency, predominately 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 amounts as necessary.
The following table shows the change in the product warranty liability, as required by Topic 460, Guarantees, to the FASB ASC, for the fiscal years ended July 31, 2014 and 2013:
Product Warranty Activity		2014			2013
		(in thousands)
Balance at beginning of period		$	1,217		$	1,672
Warranty reserve acquired from ECT and Multitest			1,970			—
Warranty expenditures for current period			(4,316	)		(3,866	)
Changes in liability related to pre-existing warranties			(141	)		(52	)
Provision for warranty costs in the period			4,510			3,463
Balance at end of period		$	3,240		$	1,217
Trade Accounts Receivable and Allowance for Doubtful Accounts
Trade accounts receivable are recorded at the invoiced amount, do not bear interest, and typically have a contractual maturity of ninety days or less. A majority of the Company’s trade receivables are derived from sales to large multinational semiconductor manufacturers throughout the world. The volatility of the industries that the Company serves can cause certain of its customers to experience shortages of cash, which can impact their ability to make required payments. An allowance for doubtful accounts is maintained for potential credit losses based upon the Company’s assessment of the expected collectability of all accounts receivable. The allowance for doubtful accounts is reviewed periodically to assess the adequacy of the allowances. In any circumstances in which the Company is aware of a customer’s inability to meet its financial obligations, an allowance is provided, which is based on the age of the receivables, the circumstances surrounding the customer’s financial situation, and historical experience. If circumstances change, and the financial condition of customers is adversely affected resulting in their inability to meet their financial obligations to the Company, additional allowances may be recorded.
Engineering and Product Development Costs
The Company expenses all engineering and product development costs as incurred. Expenses relating to certain software development costs, subject to capitalization in accordance with the Topic 985, Software, to the FASB ASC, were insignificant.
Shipping and Handling Costs
Shipping and handling costs are included in cost of sales in the consolidated statements of operations. Shipping and handling costs were $4.7 million, $2.7 million, and $3.4 million for fiscal years ended July 31, 2014, 2013, and 2012, respectively.
Income Taxes
The Company recorded an income tax provision of $0.8 million for the fiscal year ended July 31, 2014 (fiscal 2014), primarily due to $1.3 million of foreign taxes in profitable locations partially offset by $0.5 million of tax benefit relating to the release of valuation allowance as a result of the Dover Acquisition. Purchase accounting for the Dover Acquisition required the establishment of a deferred tax liability related to the book-tax basis differences of identifiable intangible assets which created an additional source of U.S. future taxable income that resulted in a release of $0.5 million of our U.S. valuation allowance.
For the fiscal year ended July 31, 2013 (fiscal 2013), the Company recorded an income tax benefit of $0.3 million, primarily due to the release of reserves related to statute of limitation expirations partially offset by foreign taxes in profitable locations.
As of July 31, 2014 and July 31, 2013, the total unrecognized income tax benefits were $6.6 million and $6.8 million, respectively, of which $3.0 million and $3.2 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 July 31, 2014 and July 31, 2013, the Company had accrued approximately $1.0 million and $0.9 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 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, 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 years prior to 1998.
As a result of the 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 the 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 is 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 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 (“2004 Plan”), 2001 Stock Plan (“2001 Plan”), 1999 Stock Plan (“1999 Plan”), and 1993 Stock Plan (“1993 Plan”). In addition, the Company assumed the StepTech, Inc. Stock Option Plan (the “STI 2000 Plan”) as part of its acquisition of StepTech, Inc. (“StepTech”) and the Credence 2005 Stock Incentive Plan (the “Credence 2005 Plan”) with its acquisition of Credence. The Company can only grant awards from the 2010 Plan.
During fiscal 2014, the Company granted 1,109,100 Restricted Stock Units (“RSUs”) to certain executives, directors and employees, with time-based vesting terms ranging from one to four years. Of these, 445,000 RSUs were granted to executives.
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 (“ASC 718”). Under ASC 718, the Company is required to recognize, as expense, the estimated fair value of all share-based payments to employees. In accordance with this standard, the Company has elected to recognize the compensation cost of all service based awards on a straight-line basis over the vesting period of the award.
For the fiscal years ended July 31, 2014, 2013, and 2012, the Company recorded stock-based compensation expense as follows:
		Fiscal Year Ended July 31,
		2014			2013			2012
		(in thousands)
Cost of sales		$	164		$	148		$	123
Engineering and product development expenses			632			611			533
Selling, general and administrative expenses			4,623			3,958			3,793
Total stock-based compensation expense		$	5,419		$	4,717		$	4,449
As of July 31, 2014, there was approximately $11.2 million of unrecognized stock-based compensation expense related to share-based equity grants to employees that is expected to be recognized over the next 3.8 years.
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 share is as follows:
		Fiscal Year Ended July 31,
		2014			2013			2012
		(in thousands, except per share data)
Net income (loss)		$	833		$	(12,127	)	$	(19,869	)

Weighted average shares outstanding—diluted			49,150			47,719			49,080
Diluted EPS		$	0.02		$	(0.25	)	$	(0.40	)
For the fiscal years ended July 31, 2014, 2013 and 2012, options to purchase approximately 0.4 million, 1.0 million, and 1.2 million shares, respectively, of common stock were not included in the calculation of diluted EPS because the effect of including the options would have been anti-dilutive. These options could be dilutive in the future. In accordance with the contingently issuable shares guidance of the FASB ASC Topic 260, Earnings Per Share, the calculation of diluted net income (loss) per share excludes 2.0 million and 1.8 million RSUs for the fiscal years ended July 31, 2013, and 2012, respectively, as to include them would have been anti-dilutive.
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, money market accounts and reverse repurchase agreements. Marketable securities consist primarily of debt securities that are classified as available-for-sale, in accordance with Topic 320, Investments—Debt and Equity Securities, to the FASB ASC. The Company also holds certain investments in commercial paper that it considers to be held to maturity, based on their maturity dates. Securities available for sale include corporate 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.
The market value and maturities of the Company’s marketable securities are as follows:
		Total Amount

Realized gains, losses and interest income are included in interest income in the Statements of Operations. Unrealized gains and losses are reflected as a separate component of comprehensive income (loss) within Stockholders’ Equity. The Company analyzes its securities portfolio for other-than-temporary impairment on a quarterly basis or upon occurrence of a significant change in circumstances. There were no other-than-temporary impairment losses recorded in the fiscal years ended July 31, 2014, 2013, or 2012.
The following table summarizes marketable securities and related unrealized gains and losses as of July 31, 2014 and 2013:

Fair Value of Financial Instruments
The Company determines its fair value measurements for assets and liabilities based upon the provisions of Topic 820, Fair Value Measurements and Disclosures, to FASB ASC.
Topic 825 to the FASB ASC, Financial Instruments, requires that disclosure be made of estimates of the fair value of financial instruments. The carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair value due to their short maturities. Marketable securities classified as available-for-sale are all debt securities and are recorded at fair value based upon quoted market prices.
Concentration of Credit and Supplier Risk
		Fiscal Year Ended July 31,
		2014			2013			2012
		(in millions except %’s)
Revenue from top ten customers			50	%		70	%		68	%
Accounts receivable from the same top ten customers		$	48.6		$	21.2		$	22.8
Sales to customers outside the United States		$	250.3		$	126		$	101.6
Financial instruments, which potentially subject the Company to concentrations of credit risk, are cash equivalents, marketable securities and accounts receivable. All of the Company’s cash equivalents and marketable securities are maintained by major financial institutions. The Company periodically reviews these investments to evaluate and minimize credit risk. Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom the Company makes substantial sales. To reduce risk, the Company routinely assesses the financial strength of its customers. The Company does not require collateral, although the Company does obtain letters of credit on sales to certain foreign customers. During fiscal 2014, the Company wrote off $0.1 million of accounts receivable. There were no write-offs for the fiscal years ended July 31, 2013 or 2012.
The Company outsources certain components and subassemblies for our test equipment to contract manufacturers other than its sole source supplier manufacturer. The Company’s products incorporate standard components and prefabricated parts manufactured to its specifications. These components and subassemblies are used to produce testers in configurations specified by its customers. Some of the standard components for the Company’s products are available from a number of different suppliers; however, many such standard components are purchased from a single supplier or a limited group of suppliers. Although the Company believes that all single sourced components currently are available in adequate amounts, shortages or delivery delays may develop in the future. The Company is dependent on certain semiconductor device manufacturers, who are sole source suppliers of custom components for its products. The Company has no written supply agreements with these sole source suppliers and purchases its custom components through individual purchase orders. The Company continuously evaluates alternative sources for the manufacture of our custom components and the supply of our standard components; however, such alternative sources may not meet its required qualifications or have capacity that is available to the Company.
Property and Equipment
Property and equipment acquired is recorded at cost. The Company provides for depreciation and amortization using the straight-line method. Charges are made to operating expenses in amounts that are sufficient to amortize the cost of the assets over their estimated useful lives. Equipment spares used for service and internally manufactured test systems used for testing components and engineering projects are recorded at cost and depreciated over three to seven years. Repair and maintenance costs that do not extend the lives of property and equipment are expensed as incurred. The Company’s property and equipment as of July 31, 2014 and July 31, 2013 are summarized as follows:
		As of July 31,						Estimated Useful
		2014			2013			Lives
		(in thousands)						(in years)
Equipment spares		$	45,572		$	58,461		5 or 7

Depreciation expense was $6.8 million, $6.5 million, and $7.8 million for the fiscal years ended July 31, 2014, 2013, and 2012, respectively.
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 U.S. 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.

Business Combination	'
	3. BUSINESS COMBINATION
	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 may be reduced by an additional $1.75 million upon certification from the Company to Dover of other specified events that have not yet occurred. The promissory notes accrue interest on the unpaid balance for each day that they remain outstanding after December 1, 2014 at a per annum rate equal to the London Interbank Offered Rate plus 10%, and may 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.
	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.
	During the three and twelve months ended July 31, 2014, the Company generated revenues of $124.3 million and $330.9 million, respectively. Of this amount, approximately $76.0 million and $176.2 million in revenues included in net product sales in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and twelve months ended July 31, 2014, respectively, was attributable to atg-Luther & Maelzer, ECT and Multitest businesses. The Acquired Businesses also generated $5.3 million and $9.3 million of net income for the three and twelve months ended July 31, 2014, which is included in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and twelve months ended July 31, 2014, respectively.
	During the three and twelve months ended July 31, 2014, the Company incurred $0.4 million and $3.9 million, respectively, of restructuring charges associated with workforce reductions and facility consolidation in connection with the Acquisition. The Company anticipates incurring additional restructuring charges of approximately $0.2 million through October 31, 2014. In accordance with the provisions of FASB ASC 805, these costs are expensed as incurred and are not allocated to the purchase price. The fair value estimates for the assets acquired and liabilities assumed were based upon calculations and valuations.
	In accordance with the provisions of ASC 805, during the three months ended April 30, 2014, the Company retroactively recorded a change in estimate of Acquired Assets of $1.4 million related to the period ended January 31, 2014. Of this amount, approximately $0.6 million related to the working capital adjustment and therefore resulted in an increase to the purchase price. The remaining $0.8 million was a change in estimate of assumed liabilities and had no impact to on the consideration paid the seller. The net impact of these adjustments resulted in a $1.4 million decrease to the bargain purchase gain.
	In accordance with the provisions of ASC 805, during the three months ended July 31, 2014, the Company retroactively recorded a change in estimate of Acquired Assets of a $4.0 million gain related to the period ended January 31, 2014. Of this amount, approximately $1.7 million resulted from the final valuation assumptions, and $2.3 million resulted from an option to purchase gain on the market valuation of the Rosenheim, Germany facility.
	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 fiscal 2014. This bargain purchase gain was recorded as a component of the other (expense) income 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 Parent 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 preliminary 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 aggregating $12.0 million, which will be 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 8.0 years. The Company engaged independent valuation advisors to assist the Company in estimating the identifiable intangible asset value. The estimated identifiable intangible asset value is 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 primarily 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 on August 1, 2013 and August 1, 2012, with pro forma adjustments to give effect to amortization of intangible assets and certain other adjustments (in thousands):

	Credit Agreement
	On November 27, 2013, in anticipation of the completion of the Dover Acquisition and to fund a portion of the purchase price therefor the Company entered into a credit agreement (the “Credit Agreement”) with Everett Charles Technologies LLC (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 in the aggregate principal amount of up to $55 million (the “Facility”).
	The Facility consists of a term loan facility for $50 million that was advanced to the Company on November 27, 2013 (the “Term Loan”) and a revolving credit facility (including a letter of credit facility) for up to $5 million (the “Revolving Loan” and, together with the Term Loan, the “Loans”) that is available from time to time for five years after November 27, 2013 (the “Closing Date”). Under the terms of the Credit Agreement, not more than one time during the period commencing on the Closing Date until the close of business on the date that is one day prior to the 42-month anniversary of the Closing Date, the Facility may be increased by an aggregate amount not to exceed $20 million through an additional facility on a pari passu basis with the Term Loan, subject to specified conditions and the agreement of one or more Lenders to participate therein. At July 31, 2014, approximately $1.0 million was outstanding in the form of standby letters of credit. The standby letters of credit have various expiration dates, of which the latest is January 2015.
	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, 7.5% of principal due the second year, 10% of principal due the third year, 12.5% of principal due the fourth year, 15% of principal due the fifth year, and a final payment of $25 million due on the fifth anniversary of the Closing Date (the “Maturity Date”). All outstanding Loans under the Facility mature on the Maturity Date unless earlier payment is required under the terms of the Credit Agreement. The Term Loan is subject to optional and mandatory prepayment in whole and part as described in the Credit Agreement, subject to certain criteria. Loans outstanding under the Facilities 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.
	Borrowings under the Facility bear interest, at a base rate plus a margin of up to 2.50% per annum, or at the London Interbank Offered Rate (“LIBOR”) plus a margin of up to 3.50% per annum, in either case based on the Company’s ratio of 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 3.50%) based on the Leverage Ratio. The selection of the interest rate formula is at the Company’s discretion. 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 under the Credit Agreement. Certain customary fees and expenses are also payable in connection with the Facility. At July 31, 2014, the interest rate in effect on the Facility was 3.73%.
	The obligations of the Company 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.
	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, consolidated leverage ratio and liquidity requirements. The Credit Agreement required the Company to maintain a consolidated leverage ratio of less than 3.00 to 1.00 as of the end of four consecutive fiscal quarters ended January 31, 2014. At January 31, 2014, the Company’s consolidated leverage ratio exceeded this ratio threshold, resulting in an event of default under the Credit Agreement. On April 15, 2014, the Company executed a First Amendment to Credit Agreement and Waiver (the “Credit Agreement Amendment and Waiver”) pursuant to which the parties thereto agreed, among other things, to waive the occurrence of the event of default resulting from the Company’s failure to meet the above described financial covenant in the Credit Agreement provided, that the Company’s consolidated leverage ratio for the four fiscal quarters ended January 31, 2014 did not exceed 3.66 to 1.00. Pursuant to the Credit Agreement Amendment and Waiver, the parties also agreed to modify the definition of “consolidated net income” to include, in the calculation of consolidated net income for periods following the closing of the Dover Acquisition, net income (or loss) attributable to the Acquired Businesses for specified periods prior to the closing of the Dover Acquisition.
	As of July 31, 2014, the Company was in compliance with all covenants under the Credit Agreement and Credit Agreement Amendment and Waiver, including the consolidated leverage ratio.
	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 certain of the Sellers.
	Subject to certain conditions, the original principal amount of the promissory notes are 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 written certification to Dover of a planned relocation from certain properties of the Acquired Businesses. Consequently, the original amount principal amount of the promissory notes issued to Dover was reduced by $2.0 million. [The promissory notes may be reduced by an additional $1.75 million upon certification from the Company to Dover of other specified events that have not yet occurred.] As of July 31, 2014, the aggregate principal amount of the promissory notes is $18.0 million. The promissory notes accrue interest on the unpaid balance for each day that they remain outstanding after December 1, 2014 at a per annum rate equal to the LIBOR plus 10%, and may be prepaid by the Company at any time without penalty prior to May 1, 2019. The promissory notes are subject to repayments of $1.3 million on December 1 and June 1 of each year starting in June 2015, until the notes are paid in full.
	Bank Term Loan—Commerzbank
	In May 2014, the Company entered into a loan agreement with Commerzbank to finance the purchase of the Company’s leased facility in Rosenheim, Germany. The principal amount of the term loan is 2.9 million euro ($3.9 million, using a July 31, 2014 exchange rate), payable over 10 years at an annual interest rate of 2.35%. Principal plus accrued interest is due quarterly over the duration of the term loan.

	Cumulative unremitted foreign earnings that are considered to be indefinitely reinvested outside of the U.S. and on which no U.S. taxes have been provided are approximately $8.3 million and $0.1 million as of July 31, 2014 and 2013. The increase compared to the prior year was associated with earnings of foreign subsidiaries acquired in connection with the Dover Acquisition. Due to net operating loss and credit carryforwards, the residual U.S. tax liability, if such amounts were remitted, would be minimal.
	Compliance with section 10-30 of FASB ASC Topic 740, Income Taxes, requires the Company to periodically evaluate the necessity of establishing or increasing a valuation allowance for deferred tax assets depending on whether it is more likely than not that a related benefit will be realized in future periods. Because of the cumulative net loss position of the Company and the uncertainty of the timing of profitability in future periods, the Company determined that a valuation allowance against its US net deferred tax assets is appropriate as the Company determined it would be more likely than not unable to realize its US deferred tax assets. There is however, no valuation allowance in certain foreign jurisdictions, as the foreign entities have cumulative income and expected future income. The valuation allowance totaled $211.9 million and $204.5 million as of July 31, 2014 and 2013, respectively. The increase in the Company’s valuation allowance compared to the prior year was primarily due to an increase in US deferred tax assets associated with the current year taxable loss generated and other book-tax basis differences partially offset by a release of valuation allowance in connection with the Dover Acquisition, where a deferred tax liability was recorded for the book-tax basis difference related to purchased intangibles and depreciable assets. The deferred tax liability provided an additional source of income to support the realizability of the Company’s pre-existing deferred tax assets and as a result, the Company released a portion of its valuation allowance and recorded a tax benefit of $0.5 million.
	As of July 31, 2014, the Company had federal net operating loss carryforwards of $367.1 million, which expire from 2019 to 2034, federal tax credit carryforwards, including research and development and foreign tax credits, of $8.0 million which expire from 2018 to 2034, state net operating loss carryforwards of $255.4 million, which expire from 2015 to 2034, and state tax credits and carryforwards of $34.8 million, of which the majority have an indefinite credit carryforward period. The remaining state tax credit carryforwards begin expiring in 2015 to 2029. The Company also has foreign net operating loss carryforwards of approximately $16.1 million in various foreign jurisdictions.
	As of July 31, 2013, the Company had federal net operating loss carryforwards of $356.4 million, which expire from 2017 to 2033, federal tax credit carryforwards, including research and development and foreign tax credits, of $6.9 million which expire from 2018 to 2033, state net operating loss carryforwards of $247.2 million, which expire from 2014 to 2033, and state tax credits and carryforwards of $33.4 million, of which the majority have an indefinite credit carryforward period. The remaining state tax credit carryforwards begin expiring in 2014 to 2028. The Company also has foreign net operating loss carryforwards of approximately $16.1 million in various foreign jurisdictions.
	As a result of the merger with Credence Systems Corporation on August 29, 2008, a greater than 50% cumulative ownership change in both entities triggered a significant limitation in net operating loss carryforward utilization. The Company’s ability to use the acquired U.S. net operating loss and credit carryforwards is subject to annual limitations 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 the currently enacted federal carryforward period, limits the amount of net operating losses that are available for utilization to approximately $202.0 million. The Company will continue to assess the realizability of these carryforwards in subsequent periods.
	A summary of the Company’s adjustments to its uncertain tax positions in the fiscal years ended July 31, 2014, 2013 and 2012 is as follows:
		July 31,			July 31,			July 31,

Decreases for lapses of statutes of limitations		(210	)		(925	)		(505	)
Balance at end of year	$	6,590		$	6,788		$	8,009
As of July 31, 2014 and 2013, the Company’s unrecognized tax benefits were $6.6 million and $6.8 million, respectively, of which $3.0 million and $3.2 million, respectively, if recognized, would impact the effective income tax rate. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. The Company has accrued a total of $1.0 million and $0.9 million, respectively, for the potential payment of interest and penalties at July 31, 2014 and July 31, 2013. The Company does not anticipate the amount of the reserve for uncertain tax positions that will be reduced over the next 12 month period will be material as the Company settles disputed items with the appropriate taxing authorities.
The Company files income tax returns with the U.S. federal government and various state and international jurisdictions, which are subject to potential examination by tax authorities. With few exceptions, the Company’s 1998 and subsequent federal and state tax years remain open by statute, principally relating to net operating loss carryforwards.
Net cash paid for income taxes during the fiscal years ended July 31, 2014, July 31, 2013 and July 31, 2012 was approximately $1.1 million, $0.2 million, and $0.1 million, respectively.

Under the 2004 ESPP, as amended, eligible employees may contribute up to 15% of their annual compensation for the purchase of common stock of the Company, subject to an annual limit of $25,000. The price paid for the common stock is equal to 85% of the price of the Company’s common stock on the last business day of a six-month offering period. The 2004 ESPP limited the number of shares that can be issued over the term of the plan to eligible employees to 400,000 shares, and the July 2009 amendment increased the number of shares that may be issued by an additional 400,000 shares. An October 2012 amendment increased the number of shares that may be issued by an additional 800,000 shares. In fiscal years 2014, 2013, and 2012, the total number of shares issued under the 2004 ESPP were 114,346, 165,572, and 146,897, respectively.

	9. SEGMENT, INDUSTRY AND GEOGRAPHIC AND SIGNIFICANT CUSTOMER SEGMENT INFORMATION
	In accordance with the provisions of Topic 280, Segment Reporting to the FASB ASC (“ASC 280”), for 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 Seminconductor 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.
	For the fiscal years ended July 31, 2013 and July 31, 2012, the Company operated as one reportable segment, that is, 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. This reportable segment is now known as the Semiconductor Test operating segment which is now aggregated into the STS reportable segment.
	The Semiconductor Test 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 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 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 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 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”.
	Segment information for the years ended July 31, 2014, 2013 and 2012 is as follows (in thousands):

Commitments and Contingencies	'
	10. 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.
	We are a defendant in a litigation matter incidental to the business that is related to customer expectations of test system performance for product that was shipped in 2006 by Credence Systems Corporation. We do not believe the plaintiff’s claims have merit and we are vigorously defending our position. An estimate of any potential loss cannot be made, and accordingly we have 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 July 31, 2014 or July 31, 2013.
	Subject to certain limitations, Xcerra indemnifies its current and former officers and directors for liability or costs they may incur upon certain events or occurrences encountered in the course of performing their duties to the Company. Although the maximum potential amount of future payments Xcerra 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 July 31, 2014 or July 31, 2013.
	As of July 31, 2014, the Company has approximately $28.7 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 2021. 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 July 31, 2014, are as follows:

	11. RESTRUCTURING
	In accordance with the provisions of Topic 420, Exit or Disposal Cost Obligation, to the FASB ASC, 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.
	As of July 31, 2014, the Company’s restructuring accrual represents 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.
	In the fiscal year ended July 31, 2009, the Company vacated certain facilities in an effort to consolidate operations and align the Company’s capacity after the merger with Credence. During fiscal 2014, the Company recognized expense of $0.3 million as a result of modifying sublease assumptions for its facility accrual associated with its Milpitas, California location. As of July 31, 2014 and 2013, the accrual for the previously restructured facility leases was $2.1 million and $2.8 million, respectively. This includes $1.1 million and $1.8 million, respectively, of long-term payments to be made for the remainder of the respective lease terms, the longest of which is through 2017. This liability is included in other long term liabilities on the Company’s consolidated balance sheets. The remainder of the accrual of $1.0 million is included in other accrued expenses on the Company’s consolidated balance sheets as of July 31, 2014 and 2013, respectively.
	On January 30, 2014, the Company announced a strategic restructuring plan in connection with ongoing efforts to reduce costs and maximize efficiencies in connection with the Dover Acquisition. The Company recorded restructuring expense of $3.5 million during fiscal 2014 related to headcount reductions in connection with the implementation of the restructuring plan.
	On April 30, 2014, the Company ceased use of its Beaverton, Oregon facility. All operations that had occurred at that location have been transferred to other locations in North America. During fiscal 2014, the Company recorded $0.1 million as restructuring expense, net of assumptions for sublease income, related to remaining lease payments on the Beaverton, Oregon facility.
	The following table sets forth the Company’s restructuring accrual activity for the three years ended July 31, 2014:

Fair_Value_Measurements

Fair Value Measurements	12 Months Ended

Fair Value Measurements	'
	12. 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 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 considers 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 July 31, 2014 and as of July 31, 2013, respectively.
					Fair Value Measurements at Reporting Date Using

	-1	Cash and cash equivalents as of July 31, 2014 and July 31, 2013 includes cash held in operating accounts of approximately $56.0 million and $25.9 million, respectively, that are not subject to fair value measurements. For purposes of this disclosure they are included as having Level 1 inputs.
	-2	Marketable securities at July 31, 2013 excluded approximately $2.8 million of commercial paper which is held-to-maturity and not subject to fair value measurements.
	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, except for the Company’s long-term debt, which includes term loans and seller-financed promissory notes. The fair value of the Company’s long-term debt at July 31, 2014 and 2013 was $68.7 million and $0, respectively, and was estimated using inputs derived principally from market observable data, including current rates offered to the Company for debt of the same or similar maturities. Within the hierarchy of fair value measurement, these are level 2 inputs.

	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 SEC.
	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 $52.4 million. Xcerra used approximately $20 million of the net proceeds from the offering to repay a portion of the outstanding principal of the Company’s bank term loan with SVB and syndicate.

Basis of Presentation	'
	Basis of Presentation
	The 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.
Preparation of Financial Statements and Use of Estimates	'
	Preparation of Financial Statements and Use of Estimates
	The accompanying financial statements have been prepared by the Company, and reflect all adjustments, which, in the opinion of management, are necessary for fair presentation. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the reporting periods. Actual results may differ from those estimates and such differences may be material to the consolidated financial statements. Such estimates relate to fair values ascribed to the assets and liabilities acquired in connection with the Dover Acquisition, revenue recognition, the allowance for doubtful accounts, inventory valuation, depreciation, product warranty costs, stock-based compensation and income taxes, among others.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes revenue based on guidance provided in Topic 605, Revenue Recognition, to the FASB ASC (“ASC 605”) and Accounting Standards Update (“ASU”) 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 product 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 product 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 included 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 spare parts is recognized on shipment.
	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 and service contracts only and excludes ECT and Multitest. These businesses generally do not provide maintenance or 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 Results of Operations.
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:
			As of July 31,
			2014			2013
			(in thousands)
	Material and purchased components		$	22,394		$	15,379
	Work-in-process			23,806			2,887
	Finished equipment, including inventory consigned to customers			23,470			10,873
	Total inventories		$	69,670		$	29,139
	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 the following: 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 July 31, 2014 and July 31, 2013, inventory is stated net of inventory reserves of $45.3 million and $41.8 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.
	The following table shows sales of previously reserved inventory and the inventory reserves released for these sales for the fiscal years ended 2014, 2013, and 2012:
			Fiscal Year Ended July 31,
			2014			2013			2012
			(in thousands)
	Sales of previously reserved inventory		$	821		$	869		$	6,859
	Inventory reserves released for these sales			483			300			2,035
Goodwill and Other Intangibles	'
	Goodwill and Other Intangibles
	In accordance with 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 July 31, 2014, the Company currently has one reporting unit to which the full balance of goodwill is allocated, its Semiconductor Test group. All of the goodwill recorded on the Company’s Consolidated Balance Sheet is related to its LTX-Credence business, since the Company did not change the underlying reporting structure of the Semiconductor Test reporting unit. Based on ASC 350-20-35-3A, as of July 31, 2014, the Company assessed qualitative factors to determine whether the two-step goodwill impairment test is necessary. Since the Company determined, based on the qualitative assessment, that it is more likely than not that its reporting unit’s fair value is greater than its carrying amount, no further impairment testing was required and no adjustment to the carrying amount of goodwill was necessary.
	The Company’s goodwill consists of the following:
	Goodwill		July 31,			July 31,
			2014			2013
			(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
	Total goodwill		$	43,030		$	43,030
	Amortizable intangible assets which relate to the acquisition of the ECT and Multitest businesses and the Credence merger, consist of the following, and are included in intangible assets, net on the Company’s Consolidated Balance Sheets:
						As of July 31, 2014

	Total intangible assets					$	27,300		$	25,729		$	1,571
	Intangible assets 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 4.3 years.
	The Company expects amortization for these intangible assets to be:
	Year ending July 31,		Amount
			(in thousands)
	2015		$	1,892
	2016			1,171
	2017			617
	2018			414
	Thereafter			771
	Total		$	4,865
	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.
Impairment of Long-Lived Assets Other Than Goodwill	'
	Impairment of Long-Lived Assets Other Than Goodwill
	On an ongoing 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 July 31, 2014 and July 31, 2013, there were no indicators that required the Company to conduct a recoverability test as of those dates.
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 or losses resulting from foreign currency remeasurement and transaction gains or losses are included in the consolidated results of operations as a component of other expense, net, and were not significant for the fiscal years ended July 31, 2014, 2013 and 2012. The functional currency of each of the Acquired Businesses is local currency, predominately 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	'
	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 amounts as necessary.
	The following table shows the change in the product warranty liability, as required by Topic 460, Guarantees, to the FASB ASC, for the fiscal years ended July 31, 2014 and 2013:
	Product Warranty Activity		2014			2013
			(in thousands)
	Balance at beginning of period		$	1,217		$	1,672
	Warranty reserve acquired from ECT and Multitest			1,970			—
	Warranty expenditures for current period			(4,316	)		(3,866	)
	Changes in liability related to pre-existing warranties			(141	)		(52	)
	Provision for warranty costs in the period			4,510			3,463
	Balance at end of period		$	3,240		$	1,217
Trade Accounts Receivable and Allowance for Doubtful Accounts	'
	Trade Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are recorded at the invoiced amount, do not bear interest, and typically have a contractual maturity of ninety days or less. A majority of the Company’s trade receivables are derived from sales to large multinational semiconductor manufacturers throughout the world. The volatility of the industries that the Company serves can cause certain of its customers to experience shortages of cash, which can impact their ability to make required payments. An allowance for doubtful accounts is maintained for potential credit losses based upon the Company’s assessment of the expected collectability of all accounts receivable. The allowance for doubtful accounts is reviewed periodically to assess the adequacy of the allowances. In any circumstances in which the Company is aware of a customer’s inability to meet its financial obligations, an allowance is provided, which is based on the age of the receivables, the circumstances surrounding the customer’s financial situation, and historical experience. If circumstances change, and the financial condition of customers is adversely affected resulting in their inability to meet their financial obligations to the Company, additional allowances may be recorded.
Engineering and Product Development Costs	'
	Engineering and Product Development Costs
	The Company expenses all engineering and product development costs as incurred. Expenses relating to certain software development costs, subject to capitalization in accordance with the Topic 985, 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 consolidated statements of operations. Shipping and handling costs were $4.7 million, $2.7 million, and $3.4 million for fiscal years ended July 31, 2014, 2013, and 2012, respectively.
Income Taxes	'
	Income Taxes
	The Company recorded an income tax provision of $0.8 million for the fiscal year ended July 31, 2014 (fiscal 2014), primarily due to $1.3 million of foreign taxes in profitable locations partially offset by $0.5 million of tax benefit relating to the release of valuation allowance as a result of the Dover Acquisition. Purchase accounting for the Dover Acquisition required the establishment of a deferred tax liability related to the book-tax basis differences of identifiable intangible assets which created an additional source of U.S. future taxable income that resulted in a release of $0.5 million of our U.S. valuation allowance.
	For the fiscal year ended July 31, 2013 (fiscal 2013), the Company recorded an income tax benefit of $0.3 million, primarily due to the release of reserves related to statute of limitation expirations partially offset by foreign taxes in profitable locations.
	As of July 31, 2014 and July 31, 2013, the total unrecognized income tax benefits were $6.6 million and $6.8 million, respectively, of which $3.0 million and $3.2 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 July 31, 2014 and July 31, 2013, the Company had accrued approximately $1.0 million and $0.9 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 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, 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 years prior to 1998.
	As a result of the 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 the 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 is approximately $10.1 million which, based on currently enacted federal carryforward periods, limits the amount of net operating losses that are currently available for utilization to approximately $202.0 million. The Company 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 (“2004 Plan”), 2001 Stock Plan (“2001 Plan”), 1999 Stock Plan (“1999 Plan”), and 1993 Stock Plan (“1993 Plan”). In addition, the Company assumed the StepTech, Inc. Stock Option Plan (the “STI 2000 Plan”) as part of its acquisition of StepTech, Inc. (“StepTech”) and the Credence 2005 Stock Incentive Plan (the “Credence 2005 Plan”) with its acquisition of Credence. The Company can only grant awards from the 2010 Plan.
	During fiscal 2014, the Company granted 1,109,100 Restricted Stock Units (“RSUs”) to certain executives, directors and employees, with time-based vesting terms ranging from one to four years. Of these, 445,000 RSUs were granted to executives.
	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 (“ASC 718”). Under ASC 718, the Company is required to recognize, as expense, the estimated fair value of all share-based payments to employees. In accordance with this standard, the Company has elected to recognize the compensation cost of all service based awards on a straight-line basis over the vesting period of the award.
	For the fiscal years ended July 31, 2014, 2013, and 2012, the Company recorded stock-based compensation expense as follows:
			Fiscal Year Ended July 31,
			2014			2013			2012
			(in thousands)
	Cost of sales		$	164		$	148		$	123
	Engineering and product development expenses			632			611			533
	Selling, general and administrative expenses			4,623			3,958			3,793
	Total stock-based compensation expense		$	5,419		$	4,717		$	4,449
	As of July 31, 2014, there was approximately $11.2 million of unrecognized stock-based compensation expense related to share-based equity grants to employees that is expected to be recognized over the next 3.8 years.
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 share is as follows:
			Fiscal Year Ended July 31,
			2014			2013			2012

	Diluted EPS		$	0.02		$	(0.25	)	$	(0.40	)
	For the fiscal years ended July 31, 2014, 2013 and 2012, options to purchase approximately 0.4 million, 1.0 million, and 1.2 million shares, respectively, of common stock were not included in the calculation of diluted EPS because the effect of including the options would have been anti-dilutive. These options could be dilutive in the future. In accordance with the contingently issuable shares guidance of the FASB ASC Topic 260, Earnings Per Share, the calculation of diluted net income (loss) per share excludes 2.0 million and 1.8 million RSUs for the fiscal years ended July 31, 2013, and 2012, respectively, as to include them would have been anti-dilutive.
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, money market accounts and reverse repurchase agreements. Marketable securities consist primarily of debt securities that are classified as available-for-sale, in accordance with Topic 320, Investments—Debt and Equity Securities, to the FASB ASC. The Company also holds certain investments in commercial paper that it considers to be held to maturity, based on their maturity dates. Securities available for sale include corporate 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.
	The market value and maturities of the Company’s marketable securities are as follows:
			Total Amount

	(a)	Included in the above figures is $0 and $2,853 of market value and amortized cost related to the Company’s held to maturity investments as of July 31, 2014 and 2013, respectively.
	Realized gains, losses and interest income are included in interest income in the Statements of Operations. Unrealized gains and losses are reflected as a separate component of comprehensive income (loss) within Stockholders’ Equity. The Company analyzes its securities portfolio for other-than-temporary impairment on a quarterly basis or upon occurrence of a significant change in circumstances. There were no other-than-temporary impairment losses recorded in the fiscal years ended July 31, 2014, 2013, or 2012.
	The following table summarizes marketable securities and related unrealized gains and losses as of July 31, 2014 and 2013:

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company determines its fair value measurements for assets and liabilities based upon the provisions of Topic 820, Fair Value Measurements and Disclosures, to FASB ASC.
	Topic 825 to the FASB ASC, Financial Instruments, requires that disclosure be made of estimates of the fair value of financial instruments. The carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair value due to their short maturities. Marketable securities classified as available-for-sale are all debt securities and are recorded at fair value based upon quoted market prices.
Concentration of Credit and Supplier Risk	'

	Financial instruments, which potentially subject the Company to concentrations of credit risk, are cash equivalents, marketable securities and accounts receivable. All of the Company’s cash equivalents and marketable securities are maintained by major financial institutions. The Company periodically reviews these investments to evaluate and minimize credit risk. Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom the Company makes substantial sales. To reduce risk, the Company routinely assesses the financial strength of its customers. The Company does not require collateral, although the Company does obtain letters of credit on sales to certain foreign customers. During fiscal 2014, the Company wrote off $0.1 million of accounts receivable. There were no write-offs for the fiscal years ended July 31, 2013 or 2012.
	The Company outsources certain components and subassemblies for our test equipment to contract manufacturers other than its sole source supplier manufacturer. The Company’s products incorporate standard components and prefabricated parts manufactured to its specifications. These components and subassemblies are used to produce testers in configurations specified by its customers. Some of the standard components for the Company’s products are available from a number of different suppliers; however, many such standard components are purchased from a single supplier or a limited group of suppliers. Although the Company believes that all single sourced components currently are available in adequate amounts, shortages or delivery delays may develop in the future. The Company is dependent on certain semiconductor device manufacturers, who are sole source suppliers of custom components for its products. The Company has no written supply agreements with these sole source suppliers and purchases its custom components through individual purchase orders. The Company continuously evaluates alternative sources for the manufacture of our custom components and the supply of our standard components; however, such alternative sources may not meet its required qualifications or have capacity that is available to the Company.
Property and Equipment	'
	Property and Equipment
	Property and equipment acquired is recorded at cost. The Company provides for depreciation and amortization using the straight-line method. Charges are made to operating expenses in amounts that are sufficient to amortize the cost of the assets over their estimated useful lives. Equipment spares used for service and internally manufactured test systems used for testing components and engineering projects are recorded at cost and depreciated over three to seven years. Repair and maintenance costs that do not extend the lives of property and equipment are expensed as incurred. The Company’s property and equipment as of July 31, 2014 and July 31, 2013 are summarized as follows:
			As of July 31,						Estimated Useful

Recent Accounting Pronouncements	'
	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 U.S. 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.
