Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies B ASIS OF P RESENTATION The accompanying consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures, normally included in annual consolidated financial statements have been condensed or omitted pursuant to those rules and regulations; however, in the opinion of management the financial information reflects all adjustments, consisting of adjustments of a normal recurring nature, necessary for fair presentation. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended June 30, 2015 which are contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on August 13, 2015. The results for the three and nine months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full fiscal year. The Company is comprised of the following operating segments: MCE and MDS. See Note L to consolidated financial statements for further discussion. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. 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 the 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. U SE OF E STIMATES The preparation of financial statements in conformity with 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 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. Total revenue recognized under multiple-deliverable revenue arrangements was 39% and 41% of total revenues in the three and nine months ended March 31, 2016 , respectively. Total revenue recognized under multiple-deliverable revenue arrangements was 26% and 27% of total revenues in the three and nine months ended March 31, 2015, respectively. 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 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. 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. 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).

Acquisitions	Acquisitions L EWIS I NNOVATIVE T ECHNOLOGIES A CQUISITION On December 16, 2015, the Company entered into a share purchase agreement (the “Share Purchase Agreement”) with Lewis Innovative Technologies, Inc. (“LIT”) and the holders of the equity interests of LIT. Pursuant to the Share Purchase Agreement, the Company completed its purchase of all of the equity interests in LIT, and LIT became a wholly-owned subsidiary of the Company. Based in Decatur, Alabama, LIT provides advanced security technology and development services necessary for protecting systems critical to national security while meeting strict Department of Defense (“DoD”) program protection requirements. LIT is included in the MDS operating segment. The Company acquired LIT for a cash purchase price of $9,756 . The Company funded the purchase with cash on hand. The purchase price was subject to a post-closing adjustment based on a determination of LIT's closing net working capital. In accordance with the Share Purchase Agreement, $1,000 of the purchase price was placed into escrow to support the post-closing working capital adjustment and the sellers' indemnification obligations. The escrow is available for indemnification claims through June 16, 2017. The Company acquired LIT free of bank debt. The following table presents the net purchase price and the preliminary fair values of the assets and liabilities of LIT: Amounts Consideration transferred Cash paid at closing $ 10,290 Working capital adjustment (244 ) Less cash and cash equivalents acquired (290 ) Net purchase price $ 9,756 Estimated fair value of tangible assets acquired and liabilities assumed Cash and cash equivalents $ 290 Accounts receivable and cost in excess of billings 290 Other current and non-current assets 175 Current liabilities (264 ) Estimated fair value of net tangible assets acquired 491 Estimated fair value of identifiable intangible assets 3,960 Estimated fair value of goodwill 5,595 Estimated fair value of assets acquired 10,046 Less cash and cash equivalents acquired (290 ) Net purchase price $ 9,756 The amounts above represent the preliminary fair value estimates as of March 31, 2016 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. The preliminary identifiable intangible asset estimates include completed technology of $3,240 , customer relationships of $590 and backlog of $130 . Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill or income, as applicable. The goodwill of $5,595 arising from the LIT acquisition largely reflects the potential synergies and expansion of the Company's service offerings across product segments and markets complementary to the Company’s existing products and markets. The LIT acquisition provides the Company with additional capabilities and expertise related to secure embedded processing applications. The acquisition is directly aligned with the Company's strategy of assembling critical and differentiated capabilities across the entire sensor processing chain. The goodwill from the LIT acquisition is included in the Company's MDS reporting unit. The Company and the shareholders of LIT have agreed to treat the acquisition of LIT as an asset purchase for tax purposes by filing the required election forms under IRC Section 338(h)(10). The Company has estimated the tax value of the intangible assets from this transaction and is amortizing the amount over 15 years for tax purposes. As of March 31, 2016 , the Company had $5,595 of goodwill deductible for tax purposes. The Company's consolidated results for the three months ended March 31, 2016 include $759 and $(286) of LIT's revenue and net loss, respectively. The Company's consolidated results for the nine months ended March 31, 2016 include $789 and $(326) of revenue and net loss, respectively, for LIT's operating results between the acquisition date and March 31, 2016 . Pursuant to the completion of the LIT acquisition, the Company incurred $231 of impairment expense related to a pre-existing relationship. LIT acquisition costs and other related expenses were immaterial during the three and nine months ended March 31, 2016 . Additionally, the Company has not furnished pro forma financial information relating to LIT because such information is not material to the Company's financial results. C ARVE- O UT B USINESS A QUISITION On March 23, 2016, the Company and Microsemi Corporation (“Microsemi”) entered into a Stock Purchase Agreement, pursuant to which, Microsemi agreed to sell all the membership interests in its custom microelectronics, RF and microwave solutions and embedded security operations of the Power and Microelectronics Group within Microsemi (“the Carve-Out Business”) to the Company for $300,000 in cash on a cash-free, debt-free basis, subject to a working capital adjustment. On May 2, 2016, the transaction closed and the Company acquired the Carve-Out Business. The Company has not completed its preliminary purchase price allocation for the Carve-Out Business as not all information required for the analysis was available. See Note N "Subsequent Events" to the consolidated financial statements for further discussion.

The value of the certificates of deposit is based on the quoted price for identical or similar instruments in markets that are not active or are directly or indirectly observable. The cost-method investment does not have a readily determinable fair value, as such the Company recorded the investment as a long term asset at cost and will continue to evaluate the asset for impairment. The change of the fair value of the Company's cost-method investment is as follows: Fair Value Balance at June 30, 2015 $ 500 Changes in fair value — Balance at March 31, 2016 $ 500

Inventory Disclosure [Abstract]
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 inventory in excess of estimated usage. The excess and obsolete inventory evaluation is based upon assumptions about future demand, history, product mix and possible alternative uses. Inventory was comprised of the following: March 31, 2016 June 30, 2015 Raw materials $ 14,827 $ 15,864 Work in process 14,817 11,190 Finished goods 4,704 4,906 Total $ 34,348 $ 31,960 There are no amounts in inventory relating to contracts having production cycles longer than one year.

The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year. The Company determines its reporting units in accordance with FASB ASC 350 by assessing whether discrete financial information is available and if management regularly reviews the operating results of that component. Following this assessment, the Company determined that its reporting units are the same as its operating segments, MCE and MDS.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax provision of $2,473 and $1,469 on income from continuing operations before income taxes of $6,999 and $6,163 for the three months ended March 31, 2016 and 2015 , respectively. The Company recorded an income tax provision of $5,417 and $2,516 on income from continuing operations before income taxes of $16,696 and $10,813 for the nine months ended March 31, 2016 and 2015 , respectively. The effective tax rates for the three and nine months ended March 31, 2016 differed from the federal statutory rate primarily due to federal research and development credits, domestic manufacturing deduction, stock compensation, and state taxes. The effective tax rates for the three and nine months ended March 31, 2015 differed from the federal statutory rate primarily due to the impact of federal research and development credits, domestic manufacturing deduction, stock compensation, state taxes, and the realization of previously unrecognized tax benefits. On December 18, 2015, the Protecting Americans from Tax Hikes Act of 2015 was enacted, which retroactively reinstated and made permanent the federal research and development tax credit effective January 1, 2015. Based on the indefinite extension, the Company estimates that there was an additional $1,572 credit earned during the period January 1, 2015 through June 30, 2016, of which $572 relating to fiscal year 2015 was recognized as a discrete benefit in the nine months ended March 31, 2016. No material changes in the Company’s unrecognized tax positions occurred during the nine months ended March 31, 2016 . The Company is currently under audit by the Internal Revenue Service for fiscal year 2013. There have been no significant changes to the status of this examination during the nine months ended March 31, 2016 . It is reasonably possible that within the next 12 months the Company’s unrecognized tax benefits, exclusive of interest, may decrease by up to $757 at the conclusion of the audit. The Company expects that the decrease, if recognized, would not affect the effective tax rate.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies L EGAL C LAIMS The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of our business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company’s cash flows, results of operations, or financial position. I NDEMNIFICATION O BLIGATIONS The Company’s standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited. On January 26, 2016, the Company received cash of $175 based on the lapse of the indemnity escrow period associated with the sale of the Company’s former MIS operating segment in January of 2015. P URCHASE C OMMITMENTS As of March 31, 2016 , the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $31,002 . L EASE C OMMITMENTS On September 1, 2015, the Company entered into a lease agreement for a new headquarters location in Andover, Massachusetts. The Company expects to occupy the new office space by May 2017. The Company's total obligation for the base rent is $21,070 based on utilization of not less than 114 square feet over the twelve year term of the lease. The Company has an option to expand its footprint to 145 square feet, or the entire facility, which would increase its corresponding total base rent obligation. This option must be exercised by the Company on or before December 31, 2018. For accounting purposes the lease commencement date is anticipated to be in August 2016, which will trigger the recognition of rental expense for the Company, although actual cash rent payments will not commence until May 2017 at the stated commencement date of the lease. O THER As part of the Company's strategy for growth, the Company continues to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed. The Company may elect from time to time to purchase and subsequently retire shares of common stock in order to settle an individual employees’ tax liability associated with vesting of a restricted stock award or exercise of stock options. These transactions would be treated as a use of cash in financing activities in the Company's statement of cash flows.

Stock-Based Compensation	Stock-Based Compensation S TOCK O PTION P LANS The number of shares authorized for issuance under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”), is 15,252 shares at March 31, 2016 . On October 21, 2015, the Company's number of shares authorized for issuance under the 2005 Plan increased 2 shares as a result of cancellations, forfeitures or terminations under the 1997 Plan. The 2005 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. All stock options are granted with an exercise price of not less than 100% of the fair value of the Company’s common stock at the date of grant and the options generally have a term of seven years. There were 2,888 shares available for future grant under the 2005 Plan at March 31, 2016 . As part of the Company's ongoing annual equity grant program for employees, the Company grants performance-based restricted stock awards to certain executives pursuant to the 2005 Plan. These performance awards vest over a three or four year requisite service period subject to the achievement of specific financial performance targets related to adjusted EBITDA as a percentage of revenue. Based on the performance targets, these awards require graded vesting that results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic stock compensation expense accordingly. E MPLOYEE S TOCK P URCHASE P LAN The number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 1,800 shares. On December 8, 2015, the Company's shareholders approved an increase in the number of shares authorized for issuance under the ESPP to 1,800 , an increase of 400 . Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were 46 and 41 shares issued under the ESPP during the nine months ended March 31, 2016 and 2015 , respectively. Shares available for future purchase under the ESPP totaled 440 at March 31, 2016 .

The Company had $114 of capitalized stock-based compensation expense on the consolidated balance sheets as of March 31, 2016 . In the prior years, the Company did not capitalize any such costs on the consolidated balance sheets, as such costs were not material. Under the fair value recognition provisions of FASB ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period, net of estimated forfeitures.

Segment Reporting [Abstract]
Operating Segment, Geographic Information and Significant Customers	Operating Segment, Geographic Information and Significant Customers Operating segments are defined as components of an enterprise evaluated regularly by the Company's chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. The Company utilizes the management approach for determining reportable segments in accordance with the authoritative guidance. The following operating segments were determined based upon the nature of the products offered to customers, the market characteristics of each operating segment and the Company's management structure: • Mercury Commercial Electronics (“MCE”): this operating segment provides affordable, innovative, commercially designed and developed, specialized processing subsystems for critical defense and intelligence applications. MCE’s technologies and capabilities include secure embedded processing modules and subsystems, RF and microwave multi-function assemblies and subsystems, as well as RF and microwave components. MCE utilizes leading edge, high performance computing technologies and open standards and open architectures to address highly data-intensive applications that include data signal, sensor and image processing, while simultaneously addressing the packaging challenges, often referred to as “SWaP” (size, weight, and power) that are common in military applications. In addition, MCE designs and builds RF and microwave components and subsystems to meet the needs of the EW, SIGINT and other high bandwidth communications requirements and applications. • Mercury Defense Systems (“MDS”): this operating segment provides significant capabilities relating to pre-integrated, open and affordable EW, EA and ECM subsystems, SIGINT, EO/IR and secure processing technologies, and radar environment test and simulation systems. Recently, MDS gained additional advanced security technology and development services capabilities related to secure embedded processing applications. MDS deploys these solutions on behalf of defense prime contractors and the Department of Defense (“DoD”), leveraging commercially available technologies and solutions (or “building blocks”) from the MCE business and other commercial suppliers. MDS leverages this technology to design and build integrated sensor processing subsystems, often including classified application-specific software and intellectual property (“IP”) for the C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), EW, and ECM markets. MDS brings significant domain expertise to customers, drawing on over 25 years of experience in EW, SIGINT, and radar environment test and simulation. The Company's operating segments were evaluated in accordance with FASB ASC 280 “ Segment Reporting ” in order to determine which operating segments qualified as reportable segments. The Company determined that both MCE and MDS met the quantitative thresholds for reporting. The accounting policies of the reportable segments are the same as those described in “Note B: Summary of Significant Accounting Policies.” The profitability measure employed by the Company and its CODM as the basis for allocating resources to segments and assessing segment performance is adjusted EBITDA. The Company believes the adjusted EBITDA financial measure assists in providing an enhanced understanding of its underlying operational measures to manage its business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. Adjusted EBITDA is defined as income from continuing operations before interest income and expense, income taxes, depreciation, amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting, litigation and settlement expenses, and stock-based compensation expense. Additionally, asset information by reportable segment is not reported because the Company and its CODM utilize consolidated asset information when making business decisions.

Business Combinations	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 the 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	U SE OF E STIMATES The preparation of financial statements in conformity with 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.
Revenue Recognition	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. Total revenue recognized under multiple-deliverable revenue arrangements was 39% and 41% of total revenues in the three and nine months ended March 31, 2016 , respectively. Total revenue recognized under multiple-deliverable revenue arrangements was 26% and 27% of total revenues in the three and nine months ended March 31, 2015, respectively. 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 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. 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. 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).
