	Summary of Significant Accounting Policies
	BASIS OF PRESENTATION
	The accompanying consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. 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, 2013 which are contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on August 16, 2013. The results for the three and nine months ended March 31, 2014 are not necessarily indicative of the results to be expected for the full fiscal year.
	The Company is comprised of the following three operating segments: MCE, MDS and MIS. The Company reports MCE as a standalone reportable segment and has aggregated MDS and MIS to form the reportable segment Mercury Defense and Intelligence Systems (“MDIS”). See Note K of the Notes 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.
	USE OF ESTIMATES
	The preparation of financial statements in conformity with U.S. 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
	The Company relies upon FASB ASC 605, Revenue Recognition to account for its revenue transactions. Revenue from sales are 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 reimbursed 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 34% and 38% of total revenues in the three and nine months ended March 31, 2014, respectively. Total revenue recognized under multiple-deliverable revenue arrangements was 30% and 31% of total revenues in the three and nine months ended March 31, 2013, 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 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 on an annual basis at a minimum. 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 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 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. 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 sales or value-added taxes.
	WEIGHTED-AVERAGE SHARES
	Weighted-average shares were calculated as follows:
		Three Months Ended March 31,		Nine Months Ended March 31,
		2014	2013	2014	2013
	Basic weighted-average shares outstanding	31,156	30,235	30,932	30,075
	Effect of dilutive equity instruments	—	175	—	—
	Diluted weighted-average shares outstanding	31,156	30,410	30,932	30,075
	Equity instruments to purchase 3,590 shares of common stock were not included in the calculation of diluted net earnings per share for the three and nine months ended March 31, 2014, because the equity instruments were anti-dilutive. Equity instruments to purchase 3,351 and 1,543 shares of common stock were not included in the calculation of diluted net earnings per share for the three and nine months ended March 31, 2013, because the equity instruments were anti-dilutive.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company measures at fair value certain financial assets and liabilities, including cash equivalents and restricted cash. 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.
	The following table summarizes the Company’s financial assets measured at fair value on a recurring basis at March 31, 2014:
		Fair Value Measurements
		31-Mar-14		Level 1		Level 2		Level 3
	Assets:
	Cash and cash equivalents	$	45,710	$	45,710	—		—
	Restricted cash	546		546		—		—
	Total	$	46,256	$	46,256	$	—	$	—
	The carrying values of cash and cash equivalents, including all U.S. Treasury Bills and money market funds, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities.

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. 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, history, product mix and possible alternative uses. Inventory was comprised of the following:
		31-Mar-14		30-Jun-13
	Raw materials	$	16,062	$	17,512
	Work in process	14,848		13,432
	Finished goods	4,420		6,488
	Total	$	35,330	$	37,432
	There are no amounts in inventory relating to contracts having production cycles longer than one year.

	Goodwill
	The following table sets forth the changes in the carrying amount of goodwill for the nine months ended March 31, 2014:
		MCE		MDS		MIS		Total
	Balance at June 30, 2013	$	133,783	$	33,768	$	8,970	$	176,521
	Goodwill adjustment for the Micronetics acquisition	595		—		—		595
	Balance at March 31, 2014	$	134,378	$	33,768	$	8,970	$	177,116
	In the nine months ended March 31, 2014, there were no triggering events, as defined by FASB ASC 350, which required an interim goodwill impairment test. The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year. Prior to the end of the measurement period for the Micronetics acquisition, August 7, 2013, the Company recorded a $91 adjustment to goodwill resulting from changes in the fair value estimates derived from additional information gathered. Additionally, the Company adjusted approximately $504 of goodwill which was identified subsequent to the measurement period as a correction of an immaterial error that was fully offset by deferred income taxes. The Company concluded that the impact of the correction was neither quantitatively nor qualitatively material to its March 31, 2014 consolidated balance sheet nor to each of the prior respective quarter ends during fiscal 2014.
	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, MDS and MIS.

Restructuring and Related Activities [Abstract]	'
Restructuring Plan	'
	Restructuring Plan
	On January 27, 2014, the Company announced a restructuring plan that was implemented as part of the final phase of integration activities relating to the Company’s recent acquisitions. The integration plan includes the consolidation of manufacturing facilities, centralization of administrative functions using common information systems and processes and realignment of research and development resources.
	During the three months ended March 31, 2014, the Company incurred restructuring charges of $3,502 associated with involuntary separation costs related to a reduction in force which eliminated 61 positions largely in administrative, manufacturing and engineering functions in addition to the Monroe, Connecticut facility closure. Future restructuring expenses associated with the integration plan are expected to be approximately $5,380, which are expected to be completed by January of 2015. These restructuring expenses affect both the MCE and MDIS reportable segments.
	The following table presents the detail of activity for the Company’s restructuring plans:
		Severance &			Facilities			Total
		Related			& Other
	Restructuring liability at June 30, 2013	$	434		$	286		$	720
	MCE restructuring charges	3,478			165			3,643
	MDIS restructuring charges	26			—			26
	Cash paid	(1,638		)	(360		)	(1,998		)
	Reversals(*)	(25		)	(60		)	(85		)
	Restructuring liability at March 31, 2014	$	2,275		$	31		$	2,306
	( *)    Reversals result from the finalization of settlements owed.
	All of the restructuring charges are classified as operating expenses in the consolidated statements of operations and comprehensive (loss) income and any remaining obligations are expected to be paid within the next twelve months. The remaining restructuring liability is classified as accrued expenses in the consolidated balance sheets.

Income Taxes	'
	Income Taxes
	The Company recorded a tax benefit of $848 and $2,232 on a loss before income taxes of $1,426 and $1,444 for the three months ended March 31, 2014 and 2013, respectively. The Company recorded a tax benefit of $2,720 and $8,075 on a loss before income taxes of $6,599 and $19,271 for the nine months ended March 31, 2014 and 2013. Income tax benefit for the three and nine months ended March 31, 2014 differed from the federal statutory rate primarily due to the impact of federal research and development tax credits, Section 199 manufacturing deduction and stock compensation. Income tax benefit for the three and nine months ended March 31, 2013 differed from the federal statutory rate primarily due to the impact of federal research and development tax credits. During the nine months ended March 31, 2014, the Company included an income tax benefit of approximately $231 for an immaterial error related to the Company's June 30, 2013 and 2012 income taxes payable. The Company concluded that the impact of the correction was neither quantitatively nor qualitatively material to the prior fiscal years ended June 30, 2013 and 2012 and each of its respective quarters ended during these fiscal years or the nine months ended March 31, 2014.
	No material changes in the Company’s unrecognized tax positions occurred during the three and nine months ended March 31, 2014. The Company estimates that the unrecognized tax benefits of up to $1,139 could be realized within the next 12 months as a result of resolutions of tax positions and the expiration of applicable statutes of limitations.

	Commitments and Contingencies
	LEGAL CLAIMS
	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.
	INDEMNIFICATION OBLIGATIONS
	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.
	PURCHASE COMMITMENTS
	As of March 31, 2014, the Company had 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 $27,590.

	Senior Unsecured Credit Facility
	On October 12, 2012, the Company entered into a credit agreement (the “Credit Agreement”) with a syndicate of commercial banks, with KeyBank National Association acting as the administrative agent. The Credit Agreement provides for a $200,000 senior unsecured revolving line of credit (the “Revolver”). The Company can borrow up to $200,000 based on consolidated EBITDA for a trailing four quarter period and subject to compliance with the financial covenants discussed below. The Revolver is available for working capital, acquisitions, and general corporate purposes of the Company and its subsidiaries. The Revolver is available for borrowing during a five year period, with interest payable periodically during such period as provided in the Credit Agreement and principal due at the maturity of the Revolver.
	The Credit Agreement has an accordion feature permitting the Company to request from the lenders an increase in the aggregate amount of the credit facility in the form of an incremental revolver or term loan in an amount not to exceed $50,000. Any such increase would require only the consent of the lenders increasing their respective commitments under the credit facility.
	The interest rates applicable to borrowings under the Credit Agreement involve various rate options that are available to the Company. The rates are calculated using a combination of conventional base rate measures plus a margin over those rates. The base rates consist of LIBOR rates or prime rates. The actual rates will depend on the level of these underlying rates plus a margin based on the Company’s leverage at the time of borrowing.
	Borrowings under the Credit Agreement are senior unsecured loans. Each of the Company’s domestic subsidiaries is a guarantor under the Credit Agreement.
	The Credit Agreement provides for conventional affirmative and negative covenants, including a maximum leverage ratio of 3.50x and a minimum interest coverage ratio of 3.0x. Each of the two ratios referred to above is calculated based on consolidated EBITDA, as defined in the Credit Agreement, for each consecutive four fiscal quarter period, after giving pro forma effect for any acquisitions or dispositions. Acquisitions are permitted under the Credit Agreement without any dollar limitation so long as, among other requirements, no default or event of default exists or would result therefore; as of March 31, 2014, the Company is in compliance with a maximum leverage ratio of 3.50x and a minimum interest coverage ratio of 3.0x. In addition, the Credit Agreement contains certain customary representations and warranties, and events of default.
	As of March 31, 2014, there was $66,082 of borrowing capacity available. There were no borrowings outstanding on the Credit Agreement; however, there were outstanding letters of credit of $4,070. The Company was in compliance with all covenants and conditions under the Credit Agreement.

There were 1,381 shares available for future grant under the 2005 Plan at March 31, 2014.
	EMPLOYEE STOCK PURCHASE PLAN
	The number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 1,400 shares. 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 55 and 52 shares issued under the ESPP during the nine months ended March 31, 2014 and 2013, respectively. Shares available for future purchase under the ESPP totaled 201 at March 31, 2014.

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 is presently organized in three operating segments. 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 delivers innovative, commercially developed, open sensor and Big Data processing systems, software and services for critical commercial, defense and intelligence applications. MCE delivers solutions that are secure and based upon open architectures and widely adopted industry standards. MCE's products include, but are not limited to, embedded processing boards, digital receiver boards, chassis-based systems using air, conduction, and proprietary cooling technologies and RF and microwave technologies, including tuners, converters, transceivers, synthesizers, switch filters, and power amplifiers and limiters. MCE delivers rapid time-to-value and world-class service and support to our commercial and defense prime contractor customers.
	•	Mercury Defense Systems (“MDS”): this operating segment delivers innovative, open sensor processing solutions to key defense prime contractors leveraging commercially available technologies and solutions from our MCE business. MDS leverages this technology to develop 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's products include, but are not limited to, Digital Radio Frequency Memory ("DRFM") jammers and radar environment simulators.
	•	Mercury Intelligence Systems (“MIS”): this operating segment delivers technologically advanced hardware and software data processing solutions and predictive analytics capabilities to address the intelligence community and Department of Defense mission needs.
	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 considered qualitative factors, including the economic characteristics of each operating segment to determine if any of its three operating segments qualified for aggregation into fewer reportable segments.
	The Company’s evaluation of the economic characteristics of its operating segments included comparisons of revenues and applicable growth rates, gross margins, operating margins, future projections, and additional non-GAAP financial measurements which indicate that MDS and MIS have similar economic characteristics. The Company also evaluated the following qualitative factors in accordance with FASB ASC 280 paragraph 10-50-11: the nature of products and services, the corresponding production processes, the types of customers, distribution methods for products and services and the nature of the corresponding regulatory environment associated with its operating segments. The Company determined each of these factors are similar for both the MDS and MIS operating segments and supports the aggregation of MDS and MIS into one reportable segment, Mercury Defense and Intelligence Systems (“MDIS”).
	The Company analyzed quantitative thresholds of each reportable segment including but not limited to reported revenues, including sales to external customers and intersegment sales or transfers, reported profits or losses, and total assets of each operating segment. The Company determined that both MCE and MDIS 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 net income (loss) before interest income and expense, income taxes, depreciation, amortization of acquired intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition costs and other related expenses, fair value adjustments from purchase accounting and stock-based compensation costs. Prior year’s amounts have been presented to reflect the current profitability measures for comparative purposes. Additionally, asset information by reportable segment is not reported because the Company and its CODM utilize consolidated asset information when making business decisions. The following is a summary of the performance of the Company’s operations by reportable segment:

Accounting Policies [Abstract]	'
Basis of Presentation	'
	BASIS OF PRESENTATION
	The accompanying consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. 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, 2013 which are contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on August 16, 2013. The results for the three and nine months ended March 31, 2014 are not necessarily indicative of the results to be expected for the full fiscal year.
	The Company is comprised of the following three operating segments: MCE, MDS and MIS. The Company reports MCE as a standalone reportable segment and has aggregated MDS and MIS to form the reportable segment Mercury Defense and Intelligence Systems (“MDIS”). See Note K of the Notes 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
Use of Estimates	'
	USE OF ESTIMATES
	The preparation of financial statements in conformity with U.S. 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	'
	REVENUE RECOGNITION
	The Company relies upon FASB ASC 605, Revenue Recognition to account for its revenue transactions. Revenue from sales are 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 reimbursed 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 34% and 38% of total revenues in the three and nine months ended March 31, 2014, respectively. Total revenue recognized under multiple-deliverable revenue arrangements was 30% and 31% of total revenues in the three and nine months ended March 31, 2013, 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 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 on an annual basis at a minimum. 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 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 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. 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 sales or value-added taxes.
