NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2016

UNAUDITED


1.	Description of the Business

ManTech International Corporation (depending on the circumstances, “ManTech,” “Company,” “we,” “our,” “ours” or “us”) provides innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Health and Human Services, Veteran Affairs and Justice, including the Federal Bureau of Investigations (FBI); the space community; and other United States of America (U.S.) government customers. We provide support to critical national security programs for approximately 50 federal agencies through approximately 1,000 current contracts. Our expertise includes cybersecurity; software and systems development; enterprise information technology (IT); multi-disciplined intelligence; program protection and mission assurance; systems engineering; test and evaluation; command, control, communications, computers, intelligence, surveillance and reconnaissance; training; supply chain management and logistics; and management consulting. We support major national missions, such as military readiness and wellness, terrorist threat detection, information security and border protection. Our employees operate primarily in the U.S. as well as numerous locations internationally.


2.	Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in the annual financial statements, prepared in accordance with accounting principles generally accepted in the U.S., have been condensed or omitted pursuant to those rules and regulations. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We recommend that you read these unaudited condensed consolidated financial statements in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC. We believe that the unaudited condensed consolidated financial statements in this Form 10-Q reflect all adjustments that are necessary to fairly present the financial position, results of operations and cash flows for the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results that can be expected for the full year.

We reclassified Employee supplemental savings plan asset from the Other line item in Cash Flows from Operating Activities of the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2015 to conform to current period presentation.


3.	Acquisitions

Oceans Edge, Inc, Cyber Division—On June 10, 2016, we completed the acquisition of certain assets of Oceans Edge, Inc., Cyber Division (OEC). The results of OEC's operations have been included in our condensed consolidated financial statements since that date. The acquisition was completed through an asset purchase agreement dated June 10, 2016, by and among Oceans Edge, Inc., Oceans Edge Cyber, LLC, certain owners of Ocean's Edge, Inc., and ManTech Advanced Systems International, Inc. OEC provides technical and professional services under government contracts in the defense and intelligence industries, including turnkey system solutions in cyber offense and defense, mission operations support and operations assessment and analysis. The OEC team of computer network operations (CNO) professionals will enhance our advanced CNO tools and research and development offerings with new business across the DoD landscape, including US CYBERCOM. The acquisition strategically strengthens our capabilities to support our federal agency customers and, specifically, to engineer and develop new, advanced solutions for wireless devices, networks, and infrastructures. We funded the acquisition with cash on hand. The asset purchase agreement did not contain provisions for contingent consideration.

For the six months ended June 30, 2016, we incurred approximately $0.9 million of acquisition costs related to the OEC transaction, which are included in the general and administrative expenses in our condensed consolidated statement of income.

The purchase price of $47.7 million was preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The goodwill recorded related to this transaction will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for OEC's capabilities in adding additional vulnerability research, development, and analysis capabilities to our existing cyber intelligence business.

In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of OEC's contracts. The components of other intangible assets associated with the acquisition were technology, customer relationships and backlog valued at $4.5 million, $11.3 million and $0.8 million, respectively. Technology represents a suite of mobile analysis and exploitation offerings which is used by customers in support of their missions. Technology is amortized straight-line over its estimated useful life of 5 years. Customer contracts and related relationships represent the underlying relationships and agreements with OEC's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful lives of approximately 20 years. Backlog is amortized straight-line over its estimated useful life of 1 year. The weighted-average amortization period for the intangible assets is 15 years.

The following table represents the preliminary purchase price allocation for OEC, as we are still in the process of reviewing the fair value of the assets acquired and liabilities assumed (in thousands):



Goodwill	$	31,762
Other intangible assets	16,600
Property and equipment	69
Accounts payable and accrued expenses	(29		)
Accrued salaries and related expenses	(720		)
Net assets acquired and liabilities assumed	$	47,682

We have not disclosed current period, nor pro forma, revenues and earnings attributable to OEC as our integration of these operations post-acquisition and the entity's accounting methods pre-acquisition make it impracticable.

Knowledge Consulting Group, Inc.—On June 15, 2015, we completed the acquisition of Knowledge Consulting Group, Inc. (KCG). The results of KCG's operations have been included in our condensed consolidated financial statements since that date. The acquisition was completed through an agreement and plan of merger dated June 15, 2015, by and among ManTech Advanced Systems International, Inc., Knight Acquisitions Corporation and KCG. KCG provides comprehensive cyber security services including cloud security, certification and accreditation and various cyber defense solutions across federal and commercial markets. The acquisition strategically positions us to pursue additional cyber work in the Department of Homeland Security, FBI and the intelligence community by leveraging our enhanced cloud security expertise. We funded the acquisition through a combination of cash on hand and borrowings under our revolving credit facility. The agreement did not contain provisions for contingent consideration.

For the six months ended June 30, 2015, we incurred approximately $0.3 million of acquisition costs related to the KCG transaction, which are included in the general and administrative expenses in our condensed consolidated statement of income.

The purchase price of $68.2 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The goodwill recorded related to this transaction will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for KCG's capabilities in providing comprehensive cyber security services throughout the Department of Defense (DoD) and intelligence community.

In allocating the purchase price, we considered among other factors analysis of historical financial performance and estimates of future performance of KCG's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $12.4 million and $0.8 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with KCG's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful lives of approximately 15 years. Backlog is amortized straight-line over its estimated useful life of 1 year. The weighted-average amortization period for the intangible assets is 14 years.

The following table represents the purchase price allocation for KCG (in thousands):



Cash and cash equivalents	$	658
Receivables	6,532
Prepaid expenses and other	460
Goodwill	47,487
Other intangible assets	13,219
Property and equipment	1,419
Investments	15
Other assets	31
Accounts payable and accrued expenses	(1,269		)
Accrued salaries and related expenses	(336		)
Billings in excess of revenue earned	(2		)
Net assets acquired and liabilities assumed	$	68,214

We have not disclosed current period, nor pro forma, revenues and earnings attributable to KCG as our integration of these operations post-acquisition and the entity's accounting methods pre-acquisition make it impracticable.

Welkin Associates, Ltd.—On April 27, 2015, we completed the acquisition of Welkin Associates, Ltd. (Welkin), formerly a wholly-owned subsidiary of Computer Sciences Corporation (CSC). The results of Welkin's operations have been included in our condensed consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated April 27, 2015, by and among ManTech International Corporation, CSC and Welkin. Welkin delivers mission-centric services in high-end systems engineering and advanced national security technology and business services. The acquisition strategically positions us to pursue large engineering and support opportunities throughout the intelligence community and DoD. We funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.

For the six months ended June 30, 2015, we incurred approximately $0.8 million of acquisition costs related to the Welkin transaction, which are included in the general and administrative expenses in our condensed consolidated statement of income.

The purchase price of $34.0 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The goodwill recorded related to this transaction will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for Welkin's capabilities in providing high-end systems engineering and support services throughout the intelligence community and DoD.

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of Welkin's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $6.0 million and $0.4 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with Welkin's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful lives of approximately 15 years. Backlog is amortized straight-line over its estimated useful life of 1 year. The weighted-average amortization period for the intangible assets is 14 years.

The following table represents the purchase price allocation for Welkin (in thousands):



Receivables	$	3,901
Prepaid expenses and other	141
Goodwill	24,436
Other intangible assets	6,350
Property and equipment	100
Accounts payable and accrued expenses	(436		)
Accrued salaries and related expenses	(492		)
Net assets acquired and liabilities assumed	$	34,000

We have not disclosed current period, nor pro forma, revenues and earnings attributable to Welkin as our integration of these operations post-acquisition and the entity's accounting methods pre-acquisition make it impracticable.


4.	Earnings Per Share

Under Accounting Standards Codification (ASC) 260, Earnings per Share, the two-class method is an earnings allocation formula that determines earnings per share for each class of common stock according to dividends declared (or accumulated) and participation rights in undistributed earnings. Under that method, basic and diluted earnings per share data are presented for each class of common stock.

In applying the two-class method, we determined that undistributed earnings should be allocated equally on a per share basis between Class A and Class B common stock. Under our Certificate of Incorporation, the holders of the common stock are entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends as may be declared by the Board of Directors. During each of the six months ended June 30, 2016 and 2015, we declared and paid two quarterly dividends, in the amount of $0.21 per share, on both classes of common stock.

Basic earnings per share has been computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during each period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period in which the shares were outstanding. Diluted earnings per share have been computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares that were outstanding during each period.

The net income available to common stockholders and weighted average number of common shares outstanding used to compute basic and diluted earnings per share for each class of common stock are as follows (in thousands, except per share amounts):



	Three months ended June 30,				Six months ended June 30,
	2016		2015		2016		2015
Distributed earnings	$	8,004	$	7,885	$	15,918	$	15,745
Undistributed earnings	6,778		4,565		12,080		8,463
Net income	$	14,782	$	12,450	$	27,998	$	24,208

Class A common stock:
Basic net income available to common stockholders	$	9,635	$	8,072	$	18,223	$	15,682
Basic weighted average common shares outstanding	24,707		24,325		24,591		24,266
Basic earnings per share	$	0.39	$	0.33	$	0.74	$	0.65

Diluted net income available to common stockholders	$	9,662	$	8,084	$	18,261	$	15,711
Effect of potential exercise of stock options	209		101		150		127
Diluted weighted average common shares outstanding	24,916		24,426		24,741		24,393
Diluted earnings per share	$	0.39	$	0.33	$	0.74	$	0.64

Class B common stock:
Basic net income available to common stockholders	$	5,147	$	4,378	$	9,775	$	8,526
Basic weighted average common shares outstanding	13,192		13,193		13,192		13,193
Basic earnings per share	$	0.39	$	0.33	$	0.74	$	0.65

Diluted net income available to common stockholders	$	5,120	$	4,366	$	9,737	$	8,497
Effect of potential exercise of stock options	—		—		—		—
Diluted weighted average common shares outstanding	13,192		13,193		13,192		13,193
Diluted earnings per share	$	0.39	$	0.33	$	0.74	$	0.64

For the three months ended June 30, 2016 and 2015, options to purchase 0.1 million and 1.8 million shares, respectively, were outstanding but not included in the computation of diluted earnings per share because the options’ effect would have been anti-dilutive. For the six months ended June 30, 2016 and 2015, options to purchase 0.7 million and 1.9 million shares, respectively,

were outstanding but not included in the computation of diluted earnings per share because the options' effect would have been anti-dilutive. For the six months ended June 30, 2016 and 2015, there were 525,212 and 155,639 shares, respectively, issued from the exercise of stock options.


5.	Receivables

We deliver a broad array of services and solutions under contracts with the U.S. government, state and local governments and commercial customers. The components of contract receivables are as follows (in thousands):



	June 30, 2016			December 31, 2015
Billed receivables	$	228,272		$	233,735
Unbilled receivables:
Amounts billable	47,849			47,900
Revenues recorded in excess of funding	22,342			19,213
Retainage	10,235			11,878
Allowance for doubtful accounts	(9,608		)	(8,473		)
Receivables—net	$	299,090		$	304,253

Amounts billable consist principally of amounts to be billed within the next month. Revenues recorded in excess of funding are billable upon receipt of contractual amendments or other modifications. The retainage is billable upon completion of contract performance and approval of final indirect expense rates by the government. Accounts receivable at June 30, 2016 are expected to be substantially collected within one year except for approximately $0.8 million, of which 91.7% is related to receivables from sales to the U.S. government. The remainder is related to receivables from contracts in which we acted as a subcontractor to other contractors.

The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts are primarily due from the U.S. government. The allowance for doubtful accounts represents our estimate for exposure to compliance, contractual issues and bad debts related to prime contractors.


6.	Property and Equipment

Major classes of property and equipment are summarized as follows (in thousands):



	June 30, 2016			December 31, 2015
Furniture and equipment	$	47,802		$	44,718
Leasehold improvements	35,971			35,733
Property and equipment—gross	83,773			80,451
Accumulated depreciation and amortization	(61,838		)	(58,012		)

8.	Debt

Revolving Credit Facility—We maintain a credit facility with a syndicate of lenders led by Bank of America, N.A, as sole administrative agent. The credit agreement provides for a $500 million revolving credit facility, with a $50 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits the Company to arrange with the lenders for the provision of additional commitments. The maturity date is June 13, 2019. On May 17, 2016, we amended the credit agreement, which among other things increased the letter of credit sublimit from $25 million to $50 million. We deferred $1.8 million in debt issuance costs, cumulatively over the agreement, which are amortized over the term of the credit agreement.

Borrowings under our revolving credit facility are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate based rate plus market-rate spreads (1.25% to 2.25% based on our

consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio).

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires the Company to comply with specified financial covenants, including the maintenance of certain leverage ratios and a certain consolidated coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintenance of certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain other actions. As of June 30, 2016, we were in compliance with the financial covenants under the credit agreement.

There was no outstanding balance on our revolving credit facility at both June 30, 2016 and December 31, 2015. The maximum available borrowing under the revolving credit facility at June 30, 2016 was $480.9 million. As of June 30, 2016, we were contingently liable under letters of credit totaling $19.1 million, which reduced our availability to borrow under our revolving credit facility.


9.	Commitments and Contingencies

Contracts with the U.S. government, including subcontracts, are subject to extensive legal and regulatory requirements and, from time-to-time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the Company, whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayments, fines or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting activities. Management believes it has adequately reserved for any losses that may be experienced from any investigation of which it is aware. The Defense Contract Audit Agency has substantially completed our incurred cost audits through 2011 with no material adjustments. The remaining audits for 2012 through 2015 are not expected to have a material effect on our financial position, results of operations or cash flow and management believes it has adequately reserved for any losses.

In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and have litigation pending under several suits. We believe that the ultimate resolution of these matters will not have a material effect on our financial position, results of operations or cash flows.

We have an outstanding performance bond in the amount of $19.0 million, which is in connection of a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company to fulfill technical support requirements for the Royal Saudi Air Force.


10.	Stock-Based Compensation

Our 2016 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. The types of equity awards available under the Plan include stock options, restricted stock and restricted stock units (RSUs). Equity awards granted under the Plan are settled in shares of Class A common stock. At the beginning of each year, the Plan provides that the number of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and Class B common stock outstanding on December 31^st of the previous year. On January 4, 2016, there were 565,190 additional shares made available for issuance under the Plan. Through June 30, 2016, the Board of Directors has authorized the issuance of up to 13,382,296 shares under this plan. Through June 30, 2016, the remaining aggregate number of shares of our common stock available for future grants under the Plan was 5,903,016. The Plan expires in March 2026.

The Plan is administered by the compensation committee of our Board of Directors, along with its delegates. Subject to the express provisions of the Plan, the committee has the Board of Directors’ authority to administer and interpret the Plan, including the discretion to determine the exercise price, vesting schedule, contractual life and the number of shares to be issued.

Stock Compensation Expense—For the three months ended June 30, 2016 and 2015, we recorded $0.2 million and $1.5 million of stock-based compensation expense, respectively. For the six months ended June 30, 2016 and 2015, we recorded $1.3 million and $2.7 million of stock-based compensation expense, respectively. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the six months ended June 30, 2016 and 2015, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted stock was $1.2 million and $1.8 million, respectively.

Stock Options—Under the Plan, we have issued stock options. A stock option granted gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined price for a specific period of time. We typically issue options that vest over three years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plan, the contractual life of the option grants may not exceed eight years. During the six months ended June 30, 2016 and 2015, we issued options that expire five years from the date of grant.

Fair Value Determination—We have used the Black-Scholes-Merton option pricing model to determine fair value of our awards on the date of grant. We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model.

The following weighted-average assumptions were used for option grants during the six months ended June 30, 2016 and 2015:

Volatility—The expected volatility of the options granted was estimated based upon historical volatility of our share price through weekly observations of our trading history.

Expected Term—The expected term of options granted to employees during the six months ended June 30, 2016 and 2015 was determined from historical exercises of the grantee population. For all grants valued during the six months ended June 30, 2016 and 2015, the options had graded vesting over three years in equal installments beginning on the first anniversary of the date of grant and a contractual term of five years.

Risk-free Interest Rate—The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.

Dividend Yield—The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. We have calculated our expected dividend yield based on an expected annual cash dividend of $0.84 per share.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the six months ended June 30, 2016 and 2015:



	Six months ended June 30,
	2016		2015
Volatility	23.66	%	27.16	%
Expected life of options	3 years		3 years
Risk-free interest rate	1.20	%	1.16	%
Dividend yield	3.00	%	3.00	%

Stock Option Activity—The weighted-average fair value of options granted during the six months ended June 30, 2016 and 2015, as determined under the Black-Scholes-Merton valuation model, was $3.99 and $5.02, respectively. Option grants that vested during the six months ended June 30, 2016 and 2015 had a combined fair value of $1.4 million and $1.8 million, respectively.

The following table summarizes stock option activity for the year ended December 31, 2015 and the six months ended June 30, 2016:



	Number of Shares		Weighted Average Exercise Price		Aggregate Intrinsic Value (in thousands)
Stock options at December 31, 2014	3,391,032		$	32.76	$	4,722
Granted	237,853		$	30.87
Exercised	(284,320	)	$	27.51	$	1,348
Cancelled and expired	(849,255	)	$	39.56
Stock options at December 31, 2015	2,495,310		$	30.86	$	3,583
Granted	89,217		$	30.03
Exercised	(525,212	)	$	29.02	$	3,050

Stock options at June 30, 2016	1,674,224		$	29.37	$	14,170

The following table summarizes non-vested stock options for the six months ended June 30, 2016:



	Number of Shares		Weighted Average Fair Value
Non-vested stock options at December 31, 2015	991,290		$	4.74
Granted	89,217		$	3.99
Vested	(278,457	)	$	4.88
Cancelled	(35,592	)	$	4.68
Non-vested stock options at June 30, 2016	766,458		$	4.60

The following table includes information concerning stock options exercisable and stock options expected to vest at June 30, 2016:



	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value (in thousands)
Stock options vested and expected to vest	1,586,716	$	29.37	3 years	$	13,439
Stock options exercisable	907,766	$	29.37	2 years	$	7,698

Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2016 was $2.1 million, which is expected to be recognized over a weighted-average period of 1 year and will be adjusted for any future changes in estimated forfeitures.

Restricted Stock—Under the Plan, we have issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors vests in one year. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest. The grant date fair value of the restricted stock is equal to the closing market price of our common stock on the date of grant.

Restricted Stock Activity—The following table summarizes the restricted stock activity during the year ended December 31, 2015 and the six months ended June 30, 2016:



	Number of Shares		Weighted Average Fair Value
Non-vested restricted stock at December 31, 2014	21,000		$	30.61
Granted	21,000		$	28.98
Vested	(21,000	)	$	30.61
Non-vested restricted stock at December 31, 2015	21,000		$	28.98
Granted	18,000		$	33.84
Vested	(21,000	)	$	28.98
Non-vested restricted stock at June 30, 2016	18,000		$	33.84

RSUs—Under the Plan, we have issued RSUs. RSUs are not actual shares, but rather a right to receive shares in the future based on the level of achievement of performance criteria. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has no voting rights until the RSUs vest. Employees who are granted RSUs do not receive dividend payments during the service period. The employees' RSUs will result in the delivery of shares if (a) performance criteria is met and (b) the employee remains employed, in good standing, through the date of the performance period. The performance period is two years. The grant date fair value of the RSUs is equal to the closing market price of our common stock on the grant date less the present value of dividends expected to be awarded during the service period. We recognize the grant date fair value of RSUs of shares we expect to issue as compensation expense ratably over the requisite service period.

RSU Activity—The following table summarizes the nonvested RSU activity during the year ended December 31, 2015 and the six months ended June 30, 2016:



	Number of Units		Weighted Average Fair Value
Non-vested RSUs at December 31, 2014	—		$	—
Granted	105,900		$	30.85
Forfeited	(12,450	)	$	30.92
Non-vested RSUs at December 31, 2015	93,450		$	30.84
Granted	104,900		$	28.26
Forfeited	(9,950	)	$	29.68
Non-vested RSUs at June 30, 2016	188,400		$	29.47


11.	Business Segment and Geographic Area Information

We have one reportable segment. We deliver a broad array of IT and technical services solutions under contracts with the U.S. government. Our U.S. government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. Revenues from the U.S. government under prime contracts and subcontracts were approximately 97.6% and 99.0% of our revenues for the six months ended June 30, 2016 and 2015, respectively. We treat sales to U.S. government customers as sales within the U.S. regardless of where the services are performed. U.S. revenues are approximately 98.0% and 99.8% of our total revenues for the three months ended June 30, 2016 and 2015, respectively. U.S. revenues are approximately 98.5% and 99.8% of our total revenues for the six months ended June 30, 2016 and 2015, respectively. International revenues were approximately 2.0% and 0.2% of our total revenues for the three months ended June 30, 2016 and 2015, respectively. International revenues were approximately 1.5% and 0.2% of our total revenues for the six months ended June 30, 2016 and 2015, respectively. Furthermore, substantially all assets from continuing operations were held in the U.S. for the six months ended June 30, 2016 and year ended December 31, 2015.

Overview

ManTech provides innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Health and Human Services, Veterans Affairs and Justice, including the Federal Bureau of Investigations; the space community; and other U.S. government customers.

We derive revenues primarily from contracts with U.S. government agencies that are focused on national security and consequently our operational results are affected by U.S. government spending levels in the areas of defense, federal health IT, intelligence and homeland security. Over the last few years, financial performance in our industry has been adversely impacted by public and political pressure regarding government funding levels, uncertainty about the appropriations process and delays in contract awards and spending. The delays in awards and competitive pressures in 2014 and 2015 have impacted our historical financial results. Currently, industry conditions are improving and award activity is returning to a more normal pace. Our level of work under contracts in support of Overseas Contingency Operations leveled off in 2015 and we expect it to remain stable through 2016. We believe we are well positioned to meet our customers' needs and grow our business as we move through 2016 and beyond.

Our strategy includes a focus on business development and bid and proposal spending on larger contract award opportunities, many in excess of $100 million. We believe our strong position as a prime contractor and our broad array of service offerings are a competitive advantage. We continue to focus on indirect spending levels to maintain competitively priced offerings. We have expanded our service offerings internationally, supporting allied governments with services similar to our federal government support. Additionally, leveraging our strong balance sheet, we will continue to pursue acquisitions that broaden our domain expertise and service offerings and/or establish relationships with new customers.

We recommend that you read this discussion and analysis in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC.

Revenues

The primary driver of our increase in revenues during the three months ended June 30, 2016 as compared to the same period in 2015 relates to revenues from new contract awards, our acquisitions and growth on existing contracts. These increases were offset by contracts and tasks that ended.

Cost of services

The increase in cost of services was primarily due to increases in revenues. As a percentage of revenues, direct labor costs decreased to 47.6% for the three months ended June 30, 2016, compared to 49.1% for the same period in 2015. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, increased to 37.5% for the three months ended June 30, 2016, compared to 35.8% for the same period in 2015, primarily due to the increased levels of materials and other direct costs.

General and administrative expenses

The decrease in general and administrative expenses was due to cost reduction measures. As a percentage of revenues, general and administrative expenses decreased for the three months ended June 30, 2016 when compared to the same period in 2015 due to the increase in revenues.

Provision for income taxes

Our effective tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in various taxing jurisdictions and their tax rates. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rates were 38.5% and 40.7% for the three months ended June 30, 2016 and 2015, respectively.

Six Months Ended June 30, 2016 Compared to the Six Months Ended June 30, 2015

The following table sets forth certain items from our consolidated statement of income and the relative percentage that certain items of expenses and earnings bear to revenues, as well as the period-to-period change from June 30, 2015 to June 30, 2016.

NET INCOME	$	27,998		$	24,208		3.5	%	3.2	%	$	3,790		15.7	%

Revenues

The primary driver of our increase in revenues during the six months ended June 30, 2016 as compared to the same period in 2015 relates to revenues from new contract awards, our acquisitions and growth on existing contracts. These increases were offset by contracts and tasks that ended during 2015.

Cost of services

The increase in cost of services was primarily due to increases in revenues. As a percentage of revenues, direct labor and related costs increased to 49.1% for the six months ended June 30, 2016, compared to 48.8% for the same period in 2015 due to improved contract activity resulting in the higher labor content on our contracts. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, remained consistent at 36.1% for the six months ended June 30, 2016 and 2015. We expect cost of services as a percentage of revenues to remain relatively stable for the remainder of 2016.

General and administrative expenses

The decrease in general and administrative expenses was due to cost reduction measures. As a percentage of revenues, general and administrative expenses decreased for the six months ended June 30, 2016 when compared to the same period in 2015 due to the increase in revenues and reduced spending. We expect general and administrative expenses as a percentage of revenues to remain relatively stable through 2016.

Provision for income taxes

Our effective tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in various taxing jurisdictions and their tax rates. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rates were 38.9% and 40.2% for the six months ended June 30, 2016 and 2015, respectively. We expect our effective tax rate to remain relatively consistent for the remainder of 2016.

Backlog

At June 30, 2016 and December 31, 2015, our backlog was $4.3 billion and $4.1 billion, respectively, of which $0.9 billion and $1.0 billion, respectively, was funded backlog. The increase in our backlog is due to our receipt of new awards. Backlog represents estimates that we calculate on a consistent basis. For additional information on how we compute backlog, see our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC.

Liquidity and Capital Resources

Historically, our primary liquidity needs have been the financing of acquisitions, working capital, payment under our cash dividend program and capital expenditures. Our primary sources of liquidity are cash provided by operations and our revolving credit facility.

On June 30, 2016, our cash and cash equivalents balance was $40.1 million. There were no outstanding borrowings under our revolving credit facility at June 30, 2016. At June 30, 2016, we were contingently liable under letters of credit totaling $19.1 million, which reduced our ability to borrow under our revolving credit facility by that amount. The maximum available borrowings under our revolving credit facility at June 30, 2016 were $480.9 million.

Generally, cash provided by operating activities is adequate to fund our operations, including payments under our regular cash dividend program. Due to fluctuations in our cash flows and level of operations, it may become necessary from time-to-time to increase borrowings under our revolving credit facility to meet cash demands.

Cash Flows from Operating Activities

Our operating cash flows are primarily affected by our ability to invoice and collect from our clients in a timely manner, our ability to manage our vendor payments and the overall profitability of our contracts. We bill most of our customers monthly after services are rendered. Our accounts receivable days sales outstanding (DSO) were 67 and 83 as of June 30, 2016 and 2015, respectively. This improvement is due to efficiencies made in our billing processes and a greater focus on collections. We expect DSO levels to remain in the upper 60's and mid-70's throughout 2016. For the six months ended June 30, 2016 and 2015, our net cash flows from operating activities were $51.2 million and $44.0 million, respectively. The increase in net cash flows from

operating activities during the six months ended June 30, 2016 when compared to the same period in 2015 was primarily due to our ability to manage vendor payments, the timing of accrued salaries and related expenses and an increase in net income, offset by the timing of accounts receivables and an increase in employee supplemental savings plan assets.

Cash Flows from Investing Activities

Our cash flows from investing activities consist primarily of business acquisitions, purchases of property and equipment and investments in capitalized software for internal use. For the six months ended June 30, 2016 and 2015, our net cash outflows from investing activities were $52.0 million and $104.7 million, respectively. During the six months ended June 30, 2016, our net cash outflows from investing activities were primarily due to the acquisition of OEC. During the six months ended June 30, 2015, our net cash outflows from investing activities were primarily due to the acquisitions of KCG and Welkin and purchases of property and equipment.

Cash Flows from Financing Activities

Our cash flows from financing activities consist primarily of dividends paid, proceeds from the exercise of stock options as well as borrowings and repayments under our revolving credit facility. For the six months ended June 30, 2016, our net cash outflows from financing activities were $0.4 million and for the six months ended June 30, 2015, net cash inflows from financing activities were $41.3 million. During the six months ended June 30, 2016, net cash outflows from financing activities were primarily due to dividends paid offset by the proceeds from the exercise of stock options and the excess tax benefits from exercise of stock options. During the six months ended June 30, 2015, net cash inflows from financing activities were primarily from net borrowings under our revolving credit facility to finance the acquisition of KCG, partially offset by our quarterly dividend payments.

Capital Resources

We believe the capital resources available to us from cash on hand of $40.1 million at June 30, 2016, our $500.0 million revolving credit facility and cash from our operations are adequate to fund our anticipated cash requirements for at least the next year, including payments under our regular cash dividend program. We anticipate financing our external growth from acquisitions and our longer-term internal growth through one or more of the following sources: cash from operations, use of our revolving credit facility; and additional borrowings of debt or issuance of equity.

Short-term Borrowings

From time-to-time, we borrow funds against our revolving credit facility for working capital requirements and funding of operations, as well as acquisitions. Borrowings bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio). In the next year we may use, as needed, our revolving credit facility or additional sources of borrowings in order to fund our anticipated cash requirements.

Cash Management

To the extent possible, we invest our available cash in short-term, investment grade securities in accordance with our investment policy. Under our investment policy, we manage our investments in accordance with the priorities of maintaining the safety of our principal, maintaining the liquidity of our investments, maximizing the yield on our investments and investing our cash to the fullest extent possible. Our investment policy provides that no investment security can have a final maturity that exceeds six months and that the weighted average maturity of the portfolio cannot exceed 60 days. Cash and cash equivalents include cash on hand, amounts due from banks and short-term investments with maturity dates of three months or less at the date of purchase.

Dividend

During each of the six months ended June 30, 2016 and 2015, we declared and paid quarterly dividends in the amount of $0.21 per share on both classes of our common stock. While we expect to continue the regular cash dividend program, any future dividends declared will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash requirements, as well as such other factors that our Board of Directors deems relevant.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use letters of credit issued to satisfy certain contractual terms with our customers. As of June 30, 2016, $19.1 million in letters of credit were issued but undrawn. We have an outstanding performance bond in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company to fulfill technical support requirements for the Royal Saudi Air Force. This performance bond is guaranteed by a letter of credit in the amount of $19.0 million. We have off-balance sheet arrangements related to operating leases. For a description of our operating leases, see Note 9 to our consolidated financial statements for the fiscal year 2015 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, filed with the SEC on February 19, 2016.

Critical Accounting Estimates and Policies

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions. Application of these policies is particularly important to the portrayal of our financial condition and results of operations. The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles (GAAP) in the U.S. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates under different assumptions or conditions. Our significant accounting policies, including the critical policies listed below, are more fully described in the notes to our consolidated financial statements for the fiscal year 2015 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, filed with the SEC on February 19, 2016.

Revenue Recognition and Cost Estimation

We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable and collectability is reasonably assured. We have a standard internal process that we use to determine whether all required criteria for revenue recognition have been met.

Our revenues consist primarily of services provided by our employees and the pass through of costs for materials and subcontract efforts under contracts with our customers. Cost of services consists primarily of compensation expenses for program personnel, the fringe benefits associated with this compensation and other direct expenses incurred to complete programs, including cost of materials and subcontract efforts.

We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price and time-and-materials contracts. Revenues for cost-reimbursable contracts are recorded as reimbursable costs are incurred, including an estimated share of the applicable contractual fees earned. For performance-based fees under cost-reimbursable contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or upon approval by the customer. For time-and-materials contracts, revenues are recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred. For long-term fixed-price production contracts, revenues are recognized at a rate per unit as the units are delivered or by other methods to measure services provided. Revenues from other long-term fixed-price contracts are recognized ratably over the contract period or by other appropriate methods to measure services provided. Contract costs are expensed as incurred except for certain limited long-term contracts noted below. For long-term contracts specifically described in the scope section of ASC 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts, we apply the percentage of completion method. Under the percentage of completion method, income is recognized at a consistent profit margin over the period of performance based on estimated profit margins at completion of the contract. This method of accounting requires estimating the total revenues and total contract cost at completion of the contract. During the performance of long-term contracts, these estimates are periodically reviewed and revisions are made as required using the cumulative catch-up method of accounting. The impact on revenues and contract profit as a result of these revisions is included in the periods in which the revisions are made. This method can result in the deferral of costs or the deferral of profit on these contracts. Because we assume the risk of performing a fixed-price contract at a set price, the failure to accurately estimate ultimate costs or to control costs during performance of the work could result, and in some instances has resulted, in reduced profits or losses for such contracts. Estimated losses on contracts at completion are recognized when identified. In certain circumstances, revenues are recognized when contract amendments have not been finalized.

Accounting for Business Combinations and Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill.

Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates.

We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value of long-lived assets may not be fully recoverable. We perform this review at the reporting unit level, which is one level below our reportable segment.

In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit is less than its carrying amount. If we elect to perform a qualitative assessment and determine that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test.

The goodwill impairment test is a two-step process performed at the reporting unit level. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying value (including goodwill). If the reporting unit's fair value exceeds its carrying value, no further procedures are required. However, if the reporting unit's fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to be performed. Step two of this test measures the amount of the impairment loss, if any. Step two of this test requires the allocation of the reporting unit's value to its assets and liabilities, including any unrecognized intangible assets in a hypothetical analysis that calculates the implied fair value of goodwill as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as a goodwill impairment charge in operations.

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach. The income approach is a valuation technique in which fair value is calculated based on forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital. The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provides a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization), and then assess the reasonableness of our implied control premium.

We have elected to perform our annual review during the fourth quarter of each calendar year. In addition, management monitors events and circumstances that could result in an impairment. A significant amount of judgment is involved in determining if an indicator of impairment has occurred between annual testing dates. Events that could cause the fair value of our long-lived assets to decrease include: changes in our business environment or market conditions, a material change in our financial outlook, including declines in expected revenue growth rates and operating margins, or a material decline in the market price for our stock. If any impairment were indicated as a result of a review, we would recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value.

Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our goodwill impairment analysis.

Accounting Standards Updates

On May 9, 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-12, Revenue From Contracts With Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, to provide a limited number of changes to its revenue recognition standard. The amendments clarify the assessment of the likelihood that revenue

will be collected from a contract, the guidance for presenting sales taxes and similar taxes and the timing for measuring customer payments that are not in cash. The amendments provide what the FASB calls a practical expedient for recognizing revenue from contracts that have been modified prior to the transition period to the new standard. ASU 2016-12 also says that a contract should be considered complete if all, or substantially all, of its revenue has been collected prior to making the transition to the new standard. In addition, this Update clarifies the disclosure requirements for businesses and other organizations that make the transition to the new standard by adjusting amounts from prior reporting periods via what is called retrospective application by the accounting board. The amendments in ASU 2016-12 become effective for fiscal years that start after December 15, 2017. We are currently evaluating the effect of adoption on our consolidated financial statements.

On April 14, 2016, the FASB issued ASU 2016-10—Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This Update finalizes Proposed ASU 2015-250 and suggests guidance for stakeholders on identifying performance obligations and licenses in customer contracts. The amendments in this Update impact entities with transactions that include contracts with customers to transfer goods or services (that are an output of the entity's ordinary activities) in exchange for consideration. They require entities to recognize revenue by following certain steps including (1) identifying the contract(s) with a customer; (2) identifying the performance obligations in a contract; (3) determining the transaction price; (4) allocating the transaction price to performance obligations in the contract and (5) recognizing revenue when, or as, the entity satisfies a performance obligation. This Update does not impact the core revenue recognition principles in Topic 606, but clarifies the following two aspects of Topic 606—the identification of performance obligations and the licensing implementation guidance—while retaining the related principles for those areas. With respect to the identification of performance obligations, the amendments in this Update are expected to (1) reduce the cost and complexity of applying the guidance on identifying promised goods or services and (2) provide guidance on assessing whether promises to transfer goods or services are distinct by evaluating the separately-identifiable-promises criterion. As for the licensing guidance, the amendments seek to improve its operability and understandability with respect to determining whether an entity's promise to grant a license provides a customer with either a right to use the entity's intellectual property or a right to access the entity's intellectual property. For public entities, the amendments are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. We do not plan on early adopting this Update. We are currently evaluating the effect of adoption on our consolidated financial statements.

On March 30, 2016, the FASB issued ASU 2016-09—Compensation-Stock Compensation (Topic 718). The FASB is issuing this Update as part of its Simplification Initiative. The amendments in this Update affect all entities that issue share-based payment awards to their employees. The areas for simplification in this Update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liability and classification on the statement of cash flows. Specifically, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The threshold to qualify for equity classifications permits withholding up to the maximum statutory tax rates in the applicable jurisdiction. Cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. We do not plan on early adopting this Update. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures and intrinsic value should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. We are currently evaluating the effect of adoption on our consolidated financial statements.

On March 17, 2016, the FASB issued ASU 2016-08—Revenue from Contracts with Customers (Topic 606)—Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which finalizes Proposed ASU 2015-290 of the same name, and clarifies the implementation guidance on principal versus agent considerations. In particular, ASU 2016-08 requires an entity to determine whether the nature of its promise is to provide the specified good or service itself (i.e., the entity is a principal) or to arrange for that good or service to be provided by the other party (i.e., the entity is an agent) when another party is involved in providing goods or services to a customer. Additionally, the amendments in this ASU require an entity that is a principal to

recognize revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer, and require an entity that is an agent to recognize revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. Notably, an entity is a principal if it controls the specified good or service before that good or service is transferred to a customer. The guidance includes indicators to assist in determining whether an entity controls a specified good or service before it is transferred to the customer, but the indicators do not override the assessment of control, should not be viewed in isolation, do not constitute a separate or additional evaluation, and should not be considered a checklist of criteria to be met in all scenarios. Because the amendments in this ASU affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective, ASU 2016-08 will become effective when the guidance in ASU 2014-09 becomes effective. Public business entities should apply the guidance in ASU 2016-08 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We are currently evaluating the effect of adoption on our consolidated financial statements.

On March 15, 2016, the FASB issued ASU 2016-07—Investments—Equity Method and Joint Ventures (Topic 323). The Update simplifies the accounting for equity method investments. The amendments in the Update eliminate the requirement in Topic 323 that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The amendments in this Update affect all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. No additional disclosures are required at transition. We are currently evaluating the effect of adoption on our consolidated financial statements.

On February 25, 2016, the FASB issued ASU 2016-02—Leases (Topic 842). The amendments in this Update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. This ASU is the final version of Proposed ASU (Revised) 2013-270—Leases (Topic 842), which has been deleted. ASU 2016-02 includes Section A—Summary and Amendments to the ASC, Section B—Conforming Amendments to Other Topics and Subtopics in the Codification and Status Tables and Section C—Background Information and Basis for Conclusions. This ASU is effective for public entities for annual periods after December 15, 2018, and interim periods therein. Early adoption is permitted for all entities. We are currently evaluating methods of adoption as well as the effect on our consolidated financial statements.

On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including ASC 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. ASU 2014-09 outlines a single set of comprehensive principles for recognizing revenue under GAAP. Among other things, it requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time. These concepts, as well as other aspects of ASU 2014-09, may change the method and/or timing of revenue recognition for certain of our contracts. ASU 2014-09 may be applied either retrospectively or through the use of a modified-retrospective method. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We are currently evaluating methods of adoption as well as the effect on our consolidated financial statements.

Other ASUs effective after June 30, 2016, are not expected to have a material effect on our condensed consolidated financial statements.


Item 3.	Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risk relates to changes in interest rates for borrowing under our revolving credit facility. At June 30, 2016, there was no outstanding balance on our revolving credit facility. Borrowings under our revolving credit facility bear interest at variable rates. A hypothetical 10% increase in interest rates would have no effect on our interest expense for the six months ended June 30, 2016.

We do not use derivative financial instruments for speculative or trading purposes. When we have excess cash, we invest in short-term, investment grade, interest-bearing securities. Our investments are made in accordance with an investment policy. Under this policy, no investment securities can have maturities exceeding six months and the weighted average maturity of the portfolio cannot exceed 60 days.


Item 4.	Controls and Procedures

Management is responsible for establishing and maintaining adequate disclosure controls and procedures. Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Quarterly Report on Form 10-Q, is accurately recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

It should be noted that a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. As a result, our disclosure controls and procedures are designed to provide reasonable assurance that such disclosure controls and procedures will meet their objectives.

As of June 30, 2016, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), management evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level described above.

There were no changes in our internal control over financial reporting during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION


Item 1.	Legal Proceedings

We are subject to certain legal proceedings, government audits, investigations, claims and disputes that arise in the ordinary course of our business. Like most large government defense contractors, our contract costs are audited and reviewed on a continual basis by an in-house staff of auditors from the Defense Contract Audit Agency. In addition to these routine audits, we are subject from time-to-time to audits and investigations by other agencies of the United States of America (U.S.) government. These audits and investigations are conducted to determine if our performance and administration of our government contracts are compliant with contractual requirements and applicable federal statutes and regulations. An audit or investigation may result in a finding that our performance, systems and administration are compliant or, alternatively, may result in the government initiating proceedings against us or our employees, including administrative proceedings seeking repayment of monies, suspension and/or debarment from doing business with the U.S. government or a particular agency or civil or criminal proceedings seeking penalties and/or fines. Audits and investigations conducted by the U.S. government frequently span several years.

Although we cannot predict the outcome of these and other legal proceedings, investigations, claims and disputes, based on the information now available to us, we do not believe the ultimate resolution of these matters, either individually or in the aggregate, will have a material adverse effect on our business, prospects, financial condition or operating results.


Item 1A.	Risk Factors

There have been no material changes from the risk factors described in the “Risk Factors” section of our Annual Report on the Form 10-K for the year ended December 31, 2015.
