Jun. 30, 2012

Principles Of Consolidation

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

Business Combinations

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under Financial Accounting Standard Boards (“FASB”) Accounting Standard Codification (“ASC”) 805, Business Combinations, (“FASB ASC 805”), for all transactions and events which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as measurement date for all assets and liabilities assumed. The Company also utilizes FASB ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

Use Of Estimates

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Revenue Recognition

REVENUE RECOGNITION

The Company relies upon FASB ASC 605, Revenue Recognition to account for its revenue transactions. Revenue from system sales is recognized upon shipment provided that title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, have been successfully demonstrated.

Certain contracts with customers require the Company to perform tests of its products prior to shipment to ensure their performance complies with the Company’s published product specifications and, on occasion, with additional customer-requested specifications. In these cases, the Company conducts such tests and, if they are completed successfully, includes a written confirmation with each order shipped. As a result, at the time of each product shipment, the Company believes that no further customer testing requirements exist and that there is no uncertainty of acceptance by its customer.

The Company enters into multiple-deliverable arrangements that may include a combination of hardware components, related integration or other services. These arrangements generally do not include any performance-, cancellation-, termination- or refund-type provisions. Total revenue recognized under multiple-deliverable revenue arrangements in fiscal 2012, 2011 and 2010 was 39%, 50% and 53% of total revenues, respectively.

The Company uses FASB Accounting Standards Update (“ASU”) No. 2009-13 (“FASB ASU 2009-13”), Multiple-Deliverable Revenue Arrangements. FASB ASU 2009-13 establishes a selling price hierarchy for determining the selling price of a deliverable, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third-party evidence (“TPE”) if VSOE is not available; and (3) best estimated selling price (“BESP”), if neither VSOE nor TPE is available. Additionally, FASB ASU 2009-13 expands the disclosure requirements related to a vendor’s multiple-deliverable revenue arrangements. This guidance was required for the Company beginning July 1, 2010; however, the Company elected to early adopt, as permitted by the guidance. As such, the Company prospectively applied the provisions of FASB ASU 2009-13 to all revenue arrangements entered into or materially modified after July 1, 2009.

Per the provisions of FASB ASU 2009-13, the Company allocates arrangement consideration to each deliverable in an arrangement based on its relative selling price. The Company generally expects that it will not be able to establish VSOE or TPE due to limited single element transactions and the nature of the markets in which the Company competes, and, as such, the Company typically determines its relative selling price using BESP.

The Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact if the product or service were sold by the Company on a standalone basis.

The Company’s determination of BESP involves the consideration of several factors based on the specific facts and circumstances of each arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, the Company’s ongoing pricing strategy and policies (as evident from the price list established and updated by management on a regular basis), the value of any enhancements that have been built into the deliverable and the characteristics of the varying markets in which the deliverable is sold.

The Company analyzes the selling prices used in its allocation of arrangement consideration at a minimum on an annual basis. Selling prices will be analyzed on a more frequent basis if a significant change in the Company’s business necessitates a more timely analysis or if the Company experiences significant variances in its selling prices.

Each deliverable within the Company’s multiple-deliverable revenue arrangements is accounted for as a separate unit of accounting under the guidance of FASB ASU 2009-13 if both of the following criteria are met: the delivered item or items have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The Company considers a deliverable to have standalone value if the item is sold separately by the Company or another vendor or if the item could be resold by the customer. Further, the Company’s revenue arrangements generally do not include a general right of return relative to delivered products.

Deliverables not meeting the criteria for being a separate unit of accounting are combined with a deliverable that does meet that criterion. The appropriate allocation of arrangement consideration and recognition of revenue is then determined for the combined unit of accounting.

For transactions involving the licensing of standalone software products and of software that is not incidental to the product, the Company recognizes revenue when there is persuasive evidence of an arrangement, delivery of the software has occurred, the price is fixed or determinable, and collection of the related receivable is reasonably assured. The Company’s software products are generally not deemed essential to the functionality of any hardware system and do not require installation by the Company or significant modification or customization of the software. If fair value of maintenance agreements related to standalone software products is obtained, the fair value of the maintenance agreement is recognized as revenue ratably over the term of each maintenance agreement.

In electing to early adopt FASB ASU 2009-13, the Company also early adopted FASB ASU No. 2009-14, Certain Revenue Arrangements That Include Software Elements (“FASB ASU 2009-14”). FASB ASU 2009-14 amends the FASB ASC 985-605, Software Revenue Recognition, to change the accounting model for revenue arrangements that include both tangible products and software elements, such that tangible products containing both software and non-software components that function together to deliver the tangible product’s essential functionality are no longer within the scope of software revenue guidance. These arrangements are instead subject to the guidance in FASB ASC 605-25. The Company monitors all multiple-element arrangements to determine if they are in scope of FASB ASU 2009-14, and when applicable will apply all relevant criteria per guidance. The adoption of FASB ASU 2009-14 has not had a material impact on the Company’s financial position or results of operations.

For multiple-element arrangements entered into prior to July 1, 2009, in accordance with FASB ASC 605-25, the Company defers the greater of the fair value of any undelivered elements of the contract or the portion of the sales price that is not payable until the undelivered elements are delivered.

The Company also engages in long-term contracts for development, production and services activities which it accounts for consistent with FASB ASC 605-35, Accounting for Performance of Construction-Type and Certain Production-Type Contracts, and other relevant revenue recognition accounting literature. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. Generally for fixed-price contracts, other than service-type contracts, revenue is recognized primarily under the percentage of completion method or, for certain short-term contracts, by the completed contract method. Revenue from service-type fixed-price contracts is recognized ratably over the contract period or by other appropriate input or output methods to measure service provided, and contract costs are expensed as incurred. The Company establishes billing terms at the time project deliverables and milestones are agreed. Revenues recognized in excess of the amounts invoiced to clients are classified as unbilled receivables. The risk to the Company on a fixed-price contract is that if estimates to complete the contract change from one period to the next, profit levels will vary from period to period. For time and materials contracts, revenue reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well as reimbursement of other billable direct costs. The risk inherent in time and materials contracts is that actual costs may differ materially from negotiated billing rates in the contract, which would directly affect operating income. For all types of contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable. Out-of-pocket expenses that are reimbursable by the customer are included in revenue and cost of revenue.

The use of contract accounting requires significant judgment relative to estimating total contract revenues and costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, anticipated increases in wages and prices for subcontractor services and materials, and the availability of subcontractor services and materials. The Company’s estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods.

The Company does not provide its customers with rights of product return, other than those related to warranty provisions that permit repair or replacement of defective goods. The Company accrues for anticipated warranty costs upon product shipment. Revenues from product royalties are recognized upon invoice by the Company. Additionally, all revenues are reported net of government assessed taxes (e.g. sales taxes or value-added taxes).

Cash And Cash Equivalents

CASH AND CASH EQUIVALENTS

Cash equivalents, consisting of highly liquid money market funds and U.S. government and U.S. government agency issues with remaining maturities of 90 days or less at the date of purchase, are carried at fair market value which approximates cost. The Company also has restricted cash which is classified as a non-current asset due to the length of the restriction.

Concentration Of Credit Risk

CONCENTRATION OF CREDIT RISK

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash, cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions that management believes are of high credit quality. At June 30, 2012 and 2011, the Company had $115,958 and $162,869, respectively, of cash and cash equivalents on deposit or invested with its financial and lending institutions.

The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary but generally does not require collateral. At June 30, 2012, five customers accounted for 59% of the Company’s receivables, unbilled receivables and cost in excess of billings. At June 30, 2011, five customers accounted for 74% of the Company’s receivables, unbilled receivables and cost in excess of billings.

Inventory

INVENTORY

Inventory is stated at the lower of cost (first-in, first-out) or market value, and consists of materials, labor and overhead. On a quarterly basis, the Company uses consistent methodologies to evaluate inventory for net realizable value. Once an item is written down, the value becomes the new inventory cost basis. The Company reduces the value of inventory for excess and obsolete inventory, consisting of on-hand and non-cancelable on-order inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, product mix and possible alternative uses.

Goodwill And Acquired Intangible Assets

GOODWILL AND ACQUIRED INTANGIBLE ASSETS

Goodwill is the amount by which the cost of the acquired net assets in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase. Goodwill is not amortized in accordance with the requirements of FASB ASC 350, Intangibles-Goodwill and Other (“FASB ASC 350”). Goodwill is assessed for impairment at least annually, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

For the year ended June 30, 2012, the Company elected to adopt FASB ASU 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment (“ASU 2011-08”). Under ASU 2011-08, the Company has the option to assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount to determine whether further impairment testing is necessary. Based on the results of the qualitative review of goodwill performed as of June 30, 2012, the Company did not identify any indicators of impairment. As such, the two-phase process was not necessary.

Acquired intangible assets result from the Company’s various business acquisitions (see Note E) and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, customer relationships, backlog, and non-compete agreements. Acquired intangible assets are reported at cost, net of accumulated amortization and are either amortized on a straight-line basis over their estimated useful lives of up to seven years or over the period the economic benefits of the intangible asset are consumed.

Long-Lived Assets

LONG-LIVED ASSETS

Long-lived assets primarily include property and equipment and acquired intangible assets. The Company periodically evaluates its long-lived assets for events and circumstances that indicate a potential impairment in accordance with FASB ASC 360, Property, Plant, and Equipment (“FASB ASC 360”). The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value.

Property And Equipment

PROPERTY AND EQUIPMENT

Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and are not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Equipment under capital lease is recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method (see Note I).

As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations.

Expenditures for major software purchases and software developed for internal use are capitalized and depreciated using the straight-line method over the estimated useful lives of the related assets, which are generally three years. For software developed for internal use, all external direct costs for material and services and certain payroll and related fringe benefit costs are capitalized in accordance with FASB ASC 350. During fiscal 2012 and 2011, the Company capitalized $1,092 and $1,000 of software development costs. Software development costs qualifying for capitalization were not material for the year ended June 30, 2010.

Deferred Revenues And Customer Advances

DEFERRED REVENUES AND CUSTOMER ADVANCES

Deferred revenues consist of deferred product revenue, billings in excess of revenues, and deferred service revenue. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because one or more of the conditions for revenue recognition have not been met. Billings in excess of revenues represents milestone billing arrangements on percentage of completion projects where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty concessions, which are recognized ratably over the term of the arrangements. Customer advances represent deposits received from customers on an order.

Income Taxes

INCOME TAXES

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“FASB ASC 740”). The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse. The Company records a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

FASB ASC 740 requires a two-step approach to recognizing and measuring uncertain tax positions. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement.

The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

Product Warranty Accrual

PRODUCT WARRANTY ACCRUAL

The Company’s product sales generally include a 12 month standard hardware warranty. At time of product shipment, the Company accrues for the estimated cost to repair or replace potentially defective products. Estimated warranty costs are based upon prior actual warranty costs for substantially similar transactions and any specifically identified warranty requirements.

Research And Development Costs

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed as incurred. Research and development costs are primarily made up of labor charges and prototype material and development expenses.

Stock-Based Compensation

STOCK-BASED COMPENSATION

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options. The fair value of stock option awards is affected by the Company’s stock price as well as valuation assumptions, including the volatility of the Company’s stock price, expected term of the option, risk-free interest rate and expected dividends. The fair value of restricted stock awards are based on the market price on the date of grant.

Net Earnings Per Share

NET EARNINGS PER SHARE

Basic net earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net earnings per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method.

Basic and diluted weighted average shares outstanding were as follows:

	Years Ended June 30,
	2012		2011		2010
Basic weighted-average shares outstanding		29,477		25,322		22,559
Effect of dilutive equity instruments		608		887		449
Diluted weighted-average shares outstanding		30,085		26,209		23,008

Weighted average equity instruments to purchase 1,244, 753 and 1,705 shares of common stock were not included in the calculation of diluted net earnings per share for the fiscal years ended June 30, 2012, 2011 and 2010, respectively, because the equity instruments were anti-dilutive.

On February 16, 2011, the Company completed a follow-on public stock offering of 5,578 shares of the Company’s common stock, at a price to the public of $17.75, generating net proceeds, after underwriting fees and expenses, of $93,605. As a result, an additional 5,578 and 2,129 weighted average shares outstanding were included in the calculation of basic and diluted net earnings per shares for fiscal 2012 and 2011.

Comprehensive Income

COMPREHENSIVE INCOME

Comprehensive income consists of net income and other comprehensive income, which includes foreign currency translation adjustments and unrealized gains on investments.

The components of accumulated other comprehensive income were as follows:

	June 30,
	2012		2011
Accumulated foreign currency translation adjustments	$	1,306	$	1,253
Accumulated net unrealized gains on investments		—		2
Total accumulated other comprehensive income	$	1,306	$	1,255

Foreign Currency

FOREIGN CURRENCY

Local currencies are used as the functional currency for the Company’s subsidiaries in Europe and Japan. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in accumulated other comprehensive income in shareholders’ equity. Gains (losses) resulting from foreign currency transactions are included in other income (expense) and were immaterial for all periods presented.

Recently Adopted Accounting Pronouncements

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 1, 2011, the Company elected to adopted FASB ASU 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment (“ASU 2011-08”): an amendment of the FASB Accounting Standards Codification. The ASU permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If an entity concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it does not need to perform the two-step impairment test. The ASU is effective for the Company on July 1, 2012; however, the Company has elected to early adopt as permitted by the guidance. Upon adoption, the Company applied ASU 2011-08 to its annual goodwill impairment test using a qualitative assessment before applying a two-step goodwill impairment test. Such adoption did not have a material impact on the Company’s financial position or results of operations.

Recently Issued Accounting Pronouncements

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities, in conjunction with the International Accounting Standards Board (“IASB”)’s issuance of amendments to Disclosures—Offsetting Financial Assets and Financial Liabilities (Amendments to IFRS 7). While the Boards retained the existing offsetting models under U.S. GAAP and International Financial Reporting Standards (“IFRS”), the new standards require disclosures to allow investors to better compare financial statements prepared under U.S. GAAP with financial statements prepared under IFRS. The new standards are effective for annual periods beginning January 1, 2013, and interim periods within those annual periods. Retrospective application is required. This guidance is not expected to have a material impact to our consolidated financial statements.

In December 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. The ASU defers the new requirement to present components of reclassifications of other comprehensive income on the face of the income statement. Companies are still required to adopt the other requirements contained in the new standard on comprehensive income, ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”). The new standard and this deferral are effective for public entities as of the beginning of a fiscal year that begins after December 15, 2011 and interim and annual periods thereafter. Early adoption is permitted but full retrospective application is required. Effective July 1, 2010, the Company adopted ASU 2011-05 and has presented the components of net income and comprehensive income in one consecutive financial statement on the Company’s annual and quarterly reports filed on Form 10-K and Form 10-Q respectively.
