Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

B. Summary of Significant Accounting Policies

BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

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, 2011 which are contained in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on August 18, 2011. The results for the three and six months ended December 31, 2011 are not necessarily indicative of the results to be expected for the full fiscal year.

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

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 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 approximately 55% and 51% of total revenues in the three and six months ended December 31, 2011, respectively. Total revenue recognized under multiple-deliverable revenue arrangements was approximately 48% and 51% of total revenues in the three and six months ended December 31, 2010, respectively. Approximately 50% of the Company's multiple-deliverable revenue arrangements typically ship complete within the same quarter.

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

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

The Company allocates arrangement consideration to each deliverable in an arrangement based on its relative selling price. The Company determines the selling price of its deliverables based on the following hierarchy: (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. The Company is not able to establish TPE due to the nature of the markets in which the Company competes, and, as such, the Company determines selling price using VSOE or BESP.

VSOE is generally limited to the price charged when the same or similar product is sold separately or, if applicable, the stated substantive renewal rate in the agreement. If a product or service is seldom sold separately, it is unlikely that the Company can determine VSOE for the product or service. The Company defines VSOE as a median price of recent standalone transactions that are priced within a narrow range, as defined by the Company.

The Company's determination of BESP involves a weighting of several factors based on the specific facts and circumstances of the 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 in the price list as established and updated 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 will determine BESP for deliverables in future agreements based on the specific facts and circumstances of each arrangement.

The Company analyzes the selling prices used in its allocation of arrangement consideration at a minimum on an annual basis. Selling prices are 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 fluctuations in the selling prices of its products.

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:


	Three Months Ended December 31,				Six Months Ended December 31,
	2011		2010		2011		2010
Basic weighted-average shares outstanding		29,457		23,099		29,367		23,021
Effect of dilutive equity instruments		512		899		634		683

Diluted weighted-average shares outstanding		29,969		23,998		30,001		23,704

Equity instruments to purchase 1,500 and 925 shares of common stock were not included in the calculation of diluted net earnings per share for the three and six months ended December 31, 2011, respectively, because the equity instruments were anti-dilutive. Equity instruments to purchase 767 and 945 shares of common stock were not included in the calculation of diluted net earnings per share for the three and six months ended December 31, 2010, respectively, because the equity instruments were anti-dilutive.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In September 2011, the FASB issued ASU No. 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment, an amendment of the FASB Accounting Standards Codification. The ASU permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If an entity concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it does not need to perform the two-step impairment test. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. This guidance is not expected to have a material impact to the Company's consolidated financial statements.

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

In December 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. The ASU defers the new requirement to present components of reclassifications of other comprehensive income on the face of the income statement. Companies are still required to adopt the other requirements contained in the new standard on comprehensive income, ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income ("ASU No. 2011-05"). The new standard and this deferral are effective for public entities as of the beginning of a fiscal year that begins after December 15, 2011 and interim and annual periods thereafter. Early adoption is permitted but full retrospective application is required. Effective July 1, 2010, the Company adopted FASB ASU 2011-05 and has presented the components of net income and comprehensive income in one consecutive financial statement on the Company's 2011 Annual Report and interim quarterly reports on Form 10-Q. This guidance is not expected to have a material impact to the Company's consolidated financial statements.

C. Acquisitions

KOR and PDI ACQUISITION

On December 22, 2011, the Company and King Merger Inc., a newly formed, wholly-owned subsidiary of the Company (the "Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with KOR Electronics ("KOR"), and Shareholder Representative Services LLC, as the securityholders' representative. On December 30, 2011, the transaction closed with the Merger Sub being merged with and into KOR with KOR continuing as the surviving company and wholly-owned subsidiary of the Company (the "Merger"). By operation of the Merger, the Company acquired both KOR and its wholly-owned subsidiary, Paragon Dynamics, Inc. ("PDI"). Based in Cypress, California, KOR designs and develops digital radio frequency memory ("DRFM") units for a variety of modern EW applications, as well as radar environment simulation and test systems for defense applications. Based in Aurora, Colorado, PDI provides sophisticated analytic exploitation services and customized multi-intelligence data fusion solutions for the U.S. intelligence community. For segment reporting, KOR will be included in the Advanced Computing Solutions ("ACS") business segment and PDI will be included in MFS business segment. All operating results from both KOR and PDI have been excluded from Mercury's consolidated statements of operations, as well as ACS and MFS segment reporting, for the three and six months ended December 31, 2011 due to immateriality.

The Company acquired KOR and PDI for a net purchase price of $70,000 paid in cash. The Company funded the purchase price with cash on hand. The Company acquired KOR and PDI free of bank debt. The purchase price was subject to post-closing adjustment based on a determination of KOR's closing net working capital.

In accordance with the Merger Agreement, $10,650 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 December 30, 2013. No amounts have been released from escrow as of December 31, 2011.

The following table presents the net purchase price for the acquisition of KOR:


	Net Purchase Price
Consideration transferred
Cash paid at closing	$	71,019
Working capital adjustment		370
Less cash, cash equivalents and restricted cash acquired		(1,019	)

Net purchase price	$	70,370

The following table presents the preliminary allocation of the net purchase price for KOR:


	Net Purchase Price Allocation
Estimated fair value of tangible assets acquired and liabilities assumed
Cash, cash equivalents and restricted cash	$	1,019
Accounts receivable and cost in excess of billings		10,600
Other assets		4,054
Current liabilities		(4,843	)
Deferred income taxes		(4,684	)

Estimated fair value of net tangible assets acquired		6,146
Estimated fair value of identifiable intangible assets		12,330
Estimated fair value of goodwill		52,913

Estimated fair value of assets acquired	$	71,389
Less cash, cash equivalents and restricted cash acquired		(1,019	)

Net purchase price	$	70,370

The amounts above represent the preliminary fair value estimates as of December 31, 2011 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. 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 $52,913 arising from the KOR acquisition largely reflects the potential synergies and expansion of the Company's service offerings across product segments complementary to the Company's existing products. The KOR acquisition provides the Company with additional know-how and expertise related to radio frequency simulation and jamming technology and expansion into technical services for the U.S. intelligence community.

No revenues or expenses were recognized for KOR in the Company's results for the three and six months ended December 31, 2011.

Pro Forma Financial Information

The following tables summarize the supplemental statements of operations information on an unaudited pro forma basis as if the KOR acquisition had occurred on July 1, 2010:


	Six Months Ended December 31,
	2011		2010
Pro forma net revenues	$	137,630	$	125,562
Pro forma net income	$	11,742	$	10,661
Basic pro forma net earnings per share	$	0.40	$	0.46
Diluted pro forma net earnings per share	$	0.39	$	0.45

The pro forma results presented above are for illustrative purposes only for the applicable periods and do not purport to be indicative of the actual results which would have occurred had the transaction been completed as of the beginning of the period, nor are they indicative of results of operations which may occur in the future.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Goodwill And Acquired Intangible Assets [Abstract]

Goodwill And Acquired Intangible Assets

D. Goodwill and Acquired Intangible Assets

The following table sets forth the changes in the carrying amount of goodwill for six months ended December 31, 2011:


	Amounts
Balance at June 30, 2011	$	79,558
Goodwill allocated to KOR		33,707
Goodwill allocated to PDI		19,206

Total Goodwill arising from the KOR acquisition		52,913

Balance at December 31, 2011	$	132,471

In the six months ended December 31, 2011, there were no triggering events, as defined by FASB ASC Topic 350, Intangibles—Goodwill and Other ("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.

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, ACS and MFS. As of June 30, 2011, ACS was the only reporting unit that had a goodwill balance, and as such, the annual impairment analysis was performed for this reporting unit only. As of December 31, 2011, both ACS and MFS had goodwill balances, as such; the annual impairment analysis will be performed for each reporting unit in the fourth quarter of fiscal year 2012.

Acquired intangible assets consisted of the following:


	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Weighted Average Useful Life
December 31, 2011
Customer relationships	$	26,660	$	(8,117	)	$	18,543		6.8 years

Thereafter		6,757

Total future amortization expense	$	27,545

The following tables summarize the acquired intangible assets arising as a result of the KOR acquisition. KOR is included in the ACS reporting segment. PDI is included in the MFS reporting segment. These assets are included in the Company's gross carrying amounts as of December 31, 2011.

Preliminary estimated fair value of acquired intangible assets at December 31, 2011 for KOR is as follows:

Fair Value Of Financial Instruments

Fair Value Of Financial Instruments [Abstract]

Fair Value Of Financial Instruments

E. Fair Value of Financial Instruments

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.

The following table summarizes the Company's financial assets and liabilities measured at fair value on a recurring basis at December 31, 2011:


	Fair Value Measurements
	December 31, 2011		Level 1		Level 2		Level 3
Assets:
U.S. Treasury bills and money market funds	$	93,043	$	93,043	$	—	$	—
Restricted cash		3,281		3,281		—		—

Total	$	96,324	$	96,324	$	—	$	—

Liabilities:
Contingent consideration	$	4,900	$	—	$	—	$	4,900

The carrying values of cash and cash equivalents, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities.

The Company determines the fair value of the contingent consideration related to the LNX acquisition based on the probability of LNX attaining specific financial targets using an appropriate discount rate to present value the liability. The following table provides a rollforward of the fair value of the contingent consideration, whose fair values were determined by Level 3 inputs:


	Fair Value
Balance at June 30, 2011	$	4,854
Recognition of accretion expense in operating expenses		46

Balance at December 31, 2011	$	4,900

Inventory [Abstract]

Inventory

F. 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, product mix and possible alternative uses. Inventory was comprised of the following:


	December 31, 2011		June 30, 2011
Raw materials	$	8,934	$	7,314
Work in process		9,095		7,554
Finished goods		4,731		3,672

Total	$	22,760	$	18,540

There are no amounts in inventory relating to contracts having production cycles longer than one year.

Debt	6 Months Ended
Debt	Dec. 31, 2011
Debt [Abstract]
Debt	G. Debt Senior Secured Credit Facility The Company has a loan and security agreement (the "Loan Agreement") with Silicon Valley Bank that provides a $35,000 revolving line of credit (the "Revolver"), with interest payable monthly and the principal due at the February 11, 2014 maturity of the Revolver. The Loan Agreement provides for conventional affirmative and negative covenants, including a minimum quick ratio of 1.0 and a $15,000 minimum trailing four quarter cash flow covenant through and including June 30, 2012 (with $17,500 of minimum cash flow required thereafter). The minimum cash flow covenant is calculated as the Company's trailing-four quarter adjusted EBITDA as defined in the Loan Agreement. In addition, the Loan Agreement contains certain customary representations and warranties and limits the Company's and its subsidiaries' ability to incur liens, dispose of assets, carry out certain mergers and acquisitions, make investments and capital expenditures and defines events of default and limitations on the ability of the Company and its subsidiaries to incur additional debt. The interest rates include 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 and 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 are secured by a first-priority security interest in all of the Company's domestic assets, including intellectual property, but limited to 65% of the voting stock of foreign subsidiaries. The Company's MFS, LNX, KOR and PDI subsidiaries are guarantors and have granted a security interest in their assets in favor of Silicon Valley Bank. The Company has had no borrowings under the Loan Agreement since inception and was in compliance with all covenants as of December 31, 2011.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Commitments And Contingencies	6 Months Ended
Commitments And Contingencies	Dec. 31, 2011
Commitments And Contingencies [Abstract]
Commitments And Contingencies	H. Commitments and Contingencies LEGAL CLAIMS The U.S. Department of Justice ("DOJ") is conducting an investigation into the conduct of certain former employees of PDI in the 2008-2009 time frame and has asserted that such conduct may have constituted a violation of the Procurement Integrity Act and that civil penalties would apply to any such violations. PDI and its parent company, KOR, have been cooperating in the investigation. While the parties have engaged in discussions and correspondence regarding this matter, no resolution has been reached and no litigation has commenced. Since its acquisition of PDI and KOR, the Company has been in the process of developing a more complete assessment of the DOJ investigation. The Company is entitled to indemnity with respect to this matter pursuant to the terms of the Merger Agreement, and based on this indemnity and the associated escrow arrangements, the matter is not expected to have a material impact on the Company's cash flows, results of operations, or financial condition. In addition to the foregoing, the Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of its business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to those matters currently pending against it and intends to defend itself self 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. In connection with the divestitures of the Company's former VI, VSG, Biotech and ES/PS businesses, which occurred in January 2009, June 2009, September 2008, and May 2008, respectively, the Company provided indemnification to the buyers of the respective businesses. The Company's indemnification obligations generally cover the buyers for damages resulting from breaches of representations, warranties and covenants contained in the applicable purchase and sale agreement and generally cover pre-closing tax liabilities of the divested businesses. The Company's indemnification obligations related to divested businesses are generally subject to caps and expire at various defined future dates. PURCHASE COMMITMENTS In September 2006, the Company entered into a supply agreement with a third-party vendor to purchase certain inventory parts that went "end of life." This supply agreement, as subsequently amended, commits the vendor to acquiring and storing approximately $6,500 of inventory until August 31, 2012 and allows the Company to place orders for the inventory four times a year. Upon the earlier of January 31, 2007 or completion of the wafer fabrication process, the Company was required to and paid approximately $1,900 of the $6,500. Further, upon expiration of the agreement on August 31, 2012, if the Company does not purchase the full $6,500 in inventory, it may be required to pay a penalty equal to 35% of the remaining inventory balance. As of December 31, 2011, the remaining minimum commitment related to this agreement was $1,578, which is the 35% penalty on the remaining inventory balance. As of December 31, 2011, the Company has recorded an accrued liability of approximately $625 for the 35% penalty it anticipates paying for unpurchased inventory. As of December 31, 2011, 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 approximately $16,438.

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 2,859 shares available for future grant under the 2005 Plan at December 31, 2011.

The number of shares authorized for issuance under the 1997 Plan was 8,650 shares, of which 100 shares could be issued pursuant to restricted stock grants. The 1997 Plan provided for the grant of non-qualified and incentive stock options and restricted stock to employees and non-employees. All stock options were 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. The options typically vest over periods of zero to four years and have a maximum term of 10 years. Following shareholder approval of the 2005 Plan on November 14, 2005, the Company's Board of Directors directed that no further grants of stock options or other awards would be made under the 1997 Plan, and the 1997 Plan subsequently expired in June 2007. The foregoing does not affect any outstanding awards under the 1997 Plan, which remain in full force and effect in accordance with their terms.

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. On October 21, 2011, the Company's shareholders approved an increase in the number of shares authorized for issuance under the ESPP to 1,400, an increase of 300. 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 58 and 54 shares issued under the ESPP during the six months ended December 31, 2011 and 2010, respectively. Shares available for future purchase under the ESPP totaled 406 at December 31, 2011.

Operating Segment, Geographic Information And Significant Customers [Abstract]

Operating Segment, Geographic Information And Significant Customers

J. Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's senior management in deciding how to allocate resources and assess performance. The Company is organized in two operating segments. These reportable 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:

•

Advanced Computing Solutions: this operating segment is focused on specialized, high-performance embedded, real-time digital image and complete signal processing solutions that encompass signal acquisition including microwave front-end, digitalization, computing, storage and communications, targeted to key market segments, including defense, communications and other commercial

applications. With the addition of KOR, the ACS segment also designs and develops DRFM units for a variety of modern EW applications, as well as radar environment simulation and test systems for defense applications.

•

Mercury Federal Systems: this services-oriented operating segment supports work for the Department of Defense as well as intelligence and homeland security agencies, including the design, development, and implementation of new ISR capabilities to address present and emerging threats to U.S. forces. With the addition of PDI, our MFS segment also provides sophisticated analytic exploitation, multi-sensor fusion, and data processing services for the U.S. intelligence community.

No revenues or expenses from KOR or PDI are included in either the ACS or MFS operating segments for any of the periods presented below.

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 chief operating decision maker ("CODM") for making decisions about allocating resources to segments and assessing segment performance was income (loss) from operations prior to stock compensation expense. As such, stock-based compensation expense has been excluded from each operating segments' income (loss) from operations below and reported separately to reconcile the reported segment income (loss) from operations to the consolidated operating income reported in the consolidated statements of operations. 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:

Income Taxes	6 Months Ended
Income Taxes	Dec. 31, 2011
Income Taxes [Abstract]
Income Taxes	K. Income Taxes The Company recorded tax expense of $4,828 and $1,696 for the three months ended December 31, 2011 and 2010, respectively, on income from continuing operations before taxes of $13,873 and $6,879 for the three months ended December 31, 2011 and 2010, respectively. The Company recorded tax expense of $6,142 and $3,773 for the six months ended December 31, 2011 and 2010, respectively, on income from continuing operations before taxes of $17,840 and $12,638 for the six months ended December 31, 2011 and 2010, respectively. The effective tax rate for the six months ended December 31, 2011 and 2010 was 34% and 30%, respectively. The difference in the rates is primarily due to a full-year benefit of federal research and development tax credit in fiscal 2011compared to only a six-month benefit in fiscal 2012. The effective tax rate for six months ended December 31, 2011 and 2010 differed from the federal statutory rate primarily due to the impact of research and development tax credits and the impact of a Section 199 Manufacturing Deduction. No material changes in the Company's unrecognized tax positions occurred during the three and six months ended December 31, 2011. The Company does not expect there to be any material changes in its reserves for unrecognized tax benefits within the next 12 months.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
