| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies P RINCIPLES OF C ONSOLIDATION The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. U SE OF E STIMATES The preparation of financial statements in conformity with Generally Accepted Accounting Principles ("GAAP") 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. R ECLASSIFICATION The Company included costs related to the sustainment of its product portfolio as research and development expense, which was previously included as costs of revenues on the Consolidated Statements of Operations and Comprehensive Income. For comparative purposes, for the fiscal years ended June 30, 2016 and 2015, the Company has reclassified $2,845 and $3,981 , respectively, from costs of revenues to research and development expense. B USINESS C OMBINATIONS The Company utilizes the acquisition method of accounting under FASB 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. Other estimates include: • estimated step-ups for the fixed assets and inventory; • estimated fair values of intangible assets; and • estimated income tax assets and liabilities assumed from the acquiree. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the business acquisition date, the estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the purchase price allocation period, which is generally one year from the business acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. For changes in the valuation of intangible assets between the preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the purchase price allocation period, any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined. R EVENUE R ECOGNITION The Company relies upon FASB ASC 605, Revenue Recognition, to account for its revenue transactions. Revenue 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. Out-of-pocket expenses that are reimbursable by the customer are included in revenue and cost of revenue. 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 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. 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. In accordance with 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’s revenue arrangements generally do not include a general right of return relative to delivered products. 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. 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. 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 Company expects to bill substantially all of the unbilled receivables during fiscal 2018. 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. For all types of contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable. The Company also considers whether contracts should be combined or segmented in accordance with the applicable criteria under GAAP. The Company combines closely related contracts when all the applicable criteria under GAAP are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single project, which should be combined to reflect an overall profit rate. Similarly, the Company may separate a project, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria under GAAP are met. Judgment also is involved in determining whether a single contract or group of contracts may be segmented based on how the arrangement was negotiated and the performance criteria. The decision to combine a group of contracts or segment a contract could change the amount of revenue and gross profit recorded in a given period. 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. Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. The Company records revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. Assumed recoveries for claims included in contracts in process were not material at June 30, 2017 or 2016. The Company defines service revenues as revenue from activities that are not associated with the design, development, production, or delivery of tangible assets, software or specific capabilities sold. Examples of the Company's service revenues include: analyst services and systems engineering support, consulting, maintenance and other support, testing and installation. The Company combines its product and service revenues into a single class as service revenues are less than 10 percent of total revenues. 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). C ASH AND C ASH E QUIVALENTS Cash equivalents, consisting of highly liquid money market funds and U.S. government and U.S. government agency issues with original maturities of 90 days or less at the date of purchase, are carried at fair market value which approximates cost. F AIR V ALUE OF F INANCIAL I NSTRUMENTS The Company measures at fair value certain financial assets and liabilities, including cash equivalents, restricted cash and contingent consideration. FASB ASC 820, Fair Value Measurement and Disclosures , specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy: Level 1—Quoted prices for identical instruments in active markets; Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. C ONCENTRATION OF C REDIT R ISK 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 of high credit quality. At June 30, 2017 and 2016 , the Company had $41,637 and $81,691 , 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. At June 30, 2017 , five customers accounted for 53% of the Company's accounts receivable, unbilled receivables and costs in excess of billings. At June 30, 2016 , five customers accounted for 50% of the Company’s accounts receivable, unbilled receivables and costs in excess of billings. I NVENTORY 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 evaluates 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. S EGMENT I NFORMATION The Company uses the management approach for segment disclosure, which designates the internal organization that is used by management for making operating decisions and assessing performance as the source of its reportable segments. The Company manages its business on the basis of one reportable segment, as a commercial provider of secure sensor and safety critical mission processing subsystems for critical defense and intelligence applications. G OODWILL AND I NTANGIBLE A SSETS Goodwill is the amount by which the cost of the net assets obtained in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase (see Note G). 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 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. Intangible assets result from the Company’s various business acquisitions (see Note H) and certain licensed technologies, and consist of identifiable intangible assets, including completed technology, licensing agreements, customer relationships, trademarks, backlog, and non-compete agreements. 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 twelve years or over the period the economic benefits of the intangible asset are consumed. L ONG - LIVED A SSETS Long-lived assets primarily include property and equipment and acquired intangible assets. The Company regularly 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 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 F). 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 2017 , 2016 and 2015 , the Company capitalized $508 , $0 and $0 of software development costs. D EFERRED R EVENUES AND C USTOMER A DVANCES 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. I NCOME T AXES 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. P RODUCT W ARRANTY A CCRUAL 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. Product warranty accrual is included as part of accrued expenses in the accompanying consolidated balance sheets. The following table presents the changes in the Company's product warranty accrual. Fiscal Fiscal Fiscal Beginning balance at July 1, $ 1,523 $ 1,974 $ 2,078 Warranty assumed from CES 176 — — Warranty assumed from Delta 30 — — Warranty assumed from Carve-Out Business — 114 — Accruals for warranties issued during the period 1,328 1,976 1,465 Settlements made during the period (1,366 ) (2,541 ) (1,569 ) Ending balance at June 30, $ 1,691 $ 1,523 $ 1,974 R ESEARCH AND D EVELOPMENT C OSTS 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. S TOCK - BASED C OMPENSATION Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. Stock-based compensation expense for the Company’s performance-based restricted stock awards are amortized over the requisite service period using graded vesting. The Company’s other restricted stock awards recognize expense over the requisite service period on a straight-line basis. The Company uses the Black-Scholes valuation model for estimating the fair value on the date of grant of stock options. R ETIREMENT OF C OMMON S TOCK Stock that is repurchased or received in connection with the exercise of stock options or in order to cover tax payment obligations triggered by exercise of stock options or the vesting of restricted stock is retired immediately upon the Company’s repurchase. The Company accounts for this under the cost method and upon retirement the excess amount over par value is charged against additional paid-in capital. N ET E ARNINGS P ER S HARE 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. For all periods presented, income from continuing operations is the control number for determining whether securities are dilutive or not. Basic and diluted weighted average shares outstanding were as follows: Years Ended June 30, 2017 2016 2015 Basic weighted-average shares outstanding 41,986 34,241 32,114 Effect of dilutive equity instruments 1,032 856 825 Diluted weighted-average shares outstanding 43,018 35,097 32,939 Equity instruments to purchase 16 , 7 and 453 shares of common stock were not included in the calculation of diluted net earnings per share for the fiscal years ended June 30, 2017 , 2016 and 2015 , respectively, because the equity instruments were anti-dilutive. A CCUMULATED O THER C OMPREHENSIVE I NCOME Accumulated other comprehensive income includes foreign currency translation adjustments and pension benefit plan adjustments. The components of accumulated other comprehensive income included $(93) and $171 of accumulated foreign currency translation adjustments for the years ended June 30, 2017 and 2016 . In addition, pension benefit plan adjustments totaled $220 for the year ended June 30, 2017. There were no material accumulated net unrealized gains on investments at June 30, 2017 and 2016 . F OREIGN C URRENCY Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, United Kingdom 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 non-U.S. currency transactions are included in other income (expense), net in the Consolidated Statements of Operations and Comprehensive Income and were immaterial for all periods presented. R ECENTLY I SSUED A CCOUNTING P RONOUNCEMENTS In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard is effective for the Company on July 1, 2018, and it does not plan to early adopt this ASU. The standard permits the use of either the retrospective or cumulative effect transition method. The Company currently intends to use the retrospective transition method upon adoption of the standard. During fiscal 2017, the Company has made significant investments in its data reporting infrastructure in order to support the reporting requirements of the standard. Throughout fiscal 2018, the Company will continue enhancing its infrastructure to capture each of the specific disclosure requirements detailed in the standard. The Company is continuing to evaluate the future impact that the adoption of the standard will have on its consolidated financial statements. However, the Company does anticipate that the additional disclosure requirements will represent a significant change from current practices. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , an amendment of the FASB Accounting Standards Codification. This ASU requires lessees to recognize a right-of-use asset and lease liability for most lease arrangements. The new standard is effective for the Company on July 1, 2019. The standard mandates a modified retrospective transition method for all entities and early adoption is permitted. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments , an amendment of the FASB Accounting Standards Codification. This ASU will reduce diversity in practice for classifying cash payments and receipts in the statement of cash flows for a number of common transactions. It will also clarify when identifiable cash flows should be separated versus classified based on their predominant source or use. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is evaluating the effect that ASU 2016-15 will have on its consolidated financial statements and related disclosures. In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, an amendment of the FASB Accounting Standards Codification. This ASU requires the seller and buyer to recognize at the transaction date the current and deferred income tax consequences of intercompany asset transfers (except transfers of inventory). Under current GAAP, the seller and buyer defer the consolidated tax consequences of an intercompany asset transfer from the period of the transfer to a future period when the asset is transferred out of the consolidated group, or otherwise affects consolidated earnings. This standard will cause volatility in companies’ effective tax rates, particularly for those that transfer intangible assets to foreign subsidiaries. For public entities, the new standard is effective for annual and interim periods in fiscal years beginning after December 15, 2017. An entity may early adopt the standard but only at the beginning of an annual period for which it has not issued or made available for issuance financial statements (interim or annual). The Company is evaluating the effect that ASU 2016-16 will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , an amendment of the FASB Accounting Standards Codification. This ASU eliminates the requirement to measure the implied fair value of goodwill by assigning the fair value of a reporting unit to all assets and liabilities within that unit (“the Step 2 test”) from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited by the amount of goodwill in that reporting unit. For public business entities, the new standard is effective for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The ASU requires prospective adoption and permits early adoption for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect this guidance to have a material impact to its consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , an amendment of the FASB Accounting Standards Codification. This ASU requires employers that sponsor defined benefit pension and/or other post-retirement benefit plans to report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. Employers are required to present the other components of net benefit costs in the income statement separately from the service cost component and outside a subtotal of income from operations. Additionally, only the service cost component of net periodic pension cost will be eligible for asset capitalization. For public entities, the new standard is effective for annual periods beginning after December 15, 2017, including interim periods withi |
