NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2014

UNAUDITED

1. Description of the Business

ManTech International Corporation (depending on the circumstances, “ManTech,” “Company,” “we,” “our,” “ours” or “us”) is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Energy and Justice, including the Federal Bureau of Investigation (FBI); the healthcare and space communities; and other U.S. federal government customers. We provide support to critical national security programs for approximately 50 federal agencies through approximately 1,000 current contracts. Our expertise includes: cyber security; command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) solutions and services; information technology (IT) modernization and sustainment; intelligence/counterintelligence solutions and support; systems engineering; healthcare analytics and IT; global logistics support; test and evaluation; and environmental, range and sustainability services. 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 United States, as well as in numerous locations internationally.

2. Basis of Presentation

The accompanying unaudited 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 United States of America, have been condensed or omitted pursuant to those rules and regulations. We recommend that you read these unaudited 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, 2013, previously filed with the SEC. We believe that the unaudited 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 classify indirect cost incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2014, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2014 as compared to 2013; however, total operating costs were not affected by this change.

3. Acquisitions

7Delta Inc.—On May 23, 2014, we completed the acquisition of all equity interests in 7Delta Inc. (7Delta). The results of 7Delta's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an amended and restated stock purchase agreement dated May 23, 2014, by and among ManTech International Corporation, 7Delta, SLS Holdings, Inc. and the stockholders of SLS Holdings, Inc. 7Delta performs critical services such as applications and software development, program management, systems integration, information assurance and security architecture primarily within the healthcare community at the Department of Veteran Affairs (VA). We funded the acquisition through a combination of cash on hand and borrowings under our revolving credit facility. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2014, ManTech incurred approximately $0.6 million of acquisition costs related to the 7Delta transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The preliminary purchase price of $80.0 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The preliminary purchase price may increase or decrease depending on the completion of the working capital adjustment. We are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price and the determination of the fair value of the assets acquired and liabilities assumed. We preliminarily recorded goodwill of $69.6 million, which 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 7Delta's capabilities in providing software development, program management, system integration, information assurance and security architecture to the VA.

In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of 7Delta's contracts. The components of other intangible assets associated with the acquisition

7

were customer relationships and backlog valued at $4.8 million and $2.9 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with 7Delta's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 10 years. Backlog is amortized straight-line over its estimated useful life of 2 years. The weighted-average amortization period for the intangible assets is 7.0 years.

We have not disclosed current period, nor pro forma, revenues and earnings attributable to 7Delta as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable.

Allied Technology Group, Inc.—On February 18, 2014, we completed the acquisition of all equity interests in Allied Technology Group, Inc. (ATG). The results of ATG's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 18, 2014, by and among ManTech Advanced Systems International, Inc., Allied Technology Group, Inc. and the stockholders of ATG. ATG is an innovative engineering and information management solution company with strong customer relationships and strategic contracts with the Department of Homeland Security (DHS). ATG provides IT, engineering services, program management and training solutions to a variety of federal customers. The acquisition will enable us to deliver services through their unrestricted prime position on DHS's primary acquisition vehicles: Technical, Acquisition and Business Support Services and Enterprise Acquisition Gateway for Leading Edge Solutions II. We funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2014, ManTech incurred approximately $0.4 million of acquisition costs related to the ATG transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The purchase price of $45.0 million was preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We are still evaluating the fair value of assets acquired and liabilities assumed. We preliminarily recorded goodwill of $28.4 million, which 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 ATG's capabilities in providing technology service program management, systems engineering and information technology services to DHS.

In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ATG's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $6.4 million and $0.6 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ATG's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life 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 18.4 years.

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

The following table represents the preliminary purchase price allocation for 7Delta and ATG (in thousands):

	7Delta Inc.			Allied Technology Group, Inc.
Cash and cash equivalents	$	1,209		$	712
Receivables	9,100			11,644
Prepaid expenses and other	1,442			1,178

Goodwill	69,605			28,443

Accounts payable and accrued expenses	(7,913		)	(2,791		)
Accrued salaries and related expenses	(1,837		)	(2,155		)
Billings in excess of revenue earned	—			(148		)
Preliminary purchase price	$	80,000		$	45,000

ALTA Systems, Inc.—On January 8, 2013, we completed the acquisition of all equity interests in ALTA Systems, Inc. (ALTA). The results of ALTA's operations have been included in our consolidated financial statements since that date. The acquisition was

8

completed through a stock purchase agreement dated January 8, 2013, by and among ManTech International Corporation, ALTA Holdings LLC and the sole member of ALTA Holdings LLC. ALTA is an information technology (IT) and professional services company with valuable applications in healthcare systems and capital planning. ALTA provides a broad range of IT and professional services to government and private industry in three major areas: capital planning and investment control; system design, development and operations; and fraud detection and statistical analysis. The acquisition allows ManTech to deliver technology services through ALTA's prime position on the Centers for Medicare and Medicaid Services (CMS) Enterprise Systems Development (ESD) contract. ManTech funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2013, ManTech incurred approximately $0.1 million of acquisition costs related to the ALTA transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The purchase price of $10.2 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We have recorded total assets of $11.1 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities of $0.9 million. Included in total assets were $0.7 million in acquisition related intangible assets. We recorded goodwill of $9.1 million, which 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 ALTA's capabilities in providing technology services to the federal government in the health care sector.

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ALTA's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $0.6 million and $0.1 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ALTA's existing customers. Customer relationships and backlog are amortized straight-line over their estimated useful lives of approximately 20 years and 1 year, respectively. The weighted-average amortization period for the intangible assets is 17.1 years.

4. Earnings Per Share

Under 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 the Company’s 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 endedJune 30, 2014 and 2013, 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 common shares 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 has 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.

9

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,
	2014			2013		2014		2013
Distributed earnings	$	7,824		$	7,802	$	15,638	$	15,585
Undistributed earnings (loss)	(116		)	13,749		1,704		26,146
Net income	$	7,708		$	21,551	$	17,342	$	41,731
Class A common stock:
Basic net income available to common stockholders	$	4,976		$	13,888	$	11,192	$	26,877
Basic weighted average common shares outstanding	24,023			23,910		24,005		23,871
Basic earnings per share	$	0.21		$	0.58	$	0.47	$	1.13
Diluted net income available to common stockholders	$	4,981		$	13,894	$	11,203	$	26,892
Effect of potential exercise of stock options	69			30		69		37
Diluted weighted average common shares outstanding	24,092			23,940		24,074		23,908
Diluted earnings per share	$	0.21		$	0.58	$	0.47	$	1.12
Class B common stock:
Basic net income available to common stockholders	$	2,732		$	7,663	$	6,150	$	14,854
Basic weighted average common shares outstanding	13,193			13,193		13,193		13,193
Basic earnings per share	$	0.21		$	0.58	$	0.47	$	1.13
Diluted net income available to common stockholders	$	2,727		$	7,657	$	6,139	$	14,839
Effect of potential exercise of stock options	—			—		—		—
Diluted weighted average common shares outstanding	13,193			13,193		13,193		13,193
Diluted earnings per share	$	0.21		$	0.58	$	0.47	$	1.12

For the three months endedJune 30, 2014 and 2013, options to purchase 2.8 million and 3.3 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 endedJune 30, 2014 and 2013, options to purchase 2.8 million and 3.5 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 endedJune 30, 2014 and 2013, shares issued from the exercise of stock options were 53 thousand and 39 thousand, respectively.

5. Receivables

We deliver a broad array of information technology and technical services 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, 2014			December 31, 2013
Billed receivables	$	309,746		$	370,975
Unbilled receivables:
Amounts billable	90,837			84,582

Receivables-net	$	408,063		$	457,898

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. There is a contract with the U.S. Army that represents 10.9% and 15.3% of receivables-net at June 30, 2014 and December 31, 2013, respectively. Accounts receivable at June 30, 2014, are expected to be substantially collected within one year except for approximately $1.4 million, of which amount 91.1% is related to receivables from direct 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 the Company’s exposure to compliance issues, contractual issues and bad debt related to prime contractors.

7. Goodwill and Other Intangible Assets

Under ASC 350, Intangibles—Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. We have elected to perform this review during the second quarter of each calendar year. An entity may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (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 the 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 actual arm's length transactions. 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 provided 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, which we then compare to the control premiums in comparable transactions to assess the reasonableness of our calculations.

During the second quarter of 2014, we completed our annual goodwill impairment test. The results of this test indicated that the fair values of all reporting units were substantially in excess of their carrying values, therefore, no impairment losses were identified and performance of step two was not required. We continue to monitor events that could impact our financial outlook and our assets including potential significant reductions in government spending that could adversely impact our financial results and changes in market conditions that could result in a reduction in the fair value of our assets.

The changes in the carrying amounts of goodwill during the year ended December 31, 2013 and the period ended June 30, 2014 are as follows (in thousands):

Goodwill at December 31, 2012	$	861,912
Impairment	(118,427		)

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 $25 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. On June 13, 2014, we amended and restated the credit agreement, and extended the maturity date to June 13, 2019. We deferred $3.4 million in debt issuance costs, which are amortized over the term of the amended and restated 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 (LIBOR) base rate plus market-rate spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's 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, 2014, we were in compliance with the financial covenants under the credit agreement.

The outstanding balance on our revolving credit facility at June 30, 2014 and December 31, 2013 was $55.0 million and $0, respectively. The outstanding debt balance at June 30, 2014 is estimated to be repaid by June 30, 2015. The maximum available borrowing under our revolving credit facility at June 30, 2014 was $444.2 million. As of June 30, 2014, we were contingently liable under letters of credit totaling $0.8 million, which reduced our availability to borrow under our revolving credit facility.

13

7.25% Senior Unsecured Notes—On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes issued on April 13, 2010 for $200.0 million, which were registered under the Securities Act of 1933. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million as non-operating income on our consolidated statement of income.

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 the Company’s 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 the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayment, 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. We have settled all incurred cost submissions through 2005 with the Defense Contract Management Agency (DCMA) Corporate Administrative Contracting Officer (CACO). Settlements of the 2006 through 2013 incurred cost submission 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.

10. Stock-Based Compensation

Our 2011 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. 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 2, 2014, 557,894 additional shares were made available for issuance under the Plan. Through June 30, 2014, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 4,068,523. Through June 30, 2014, there were 4,707,168 shares of our Class A common stock that were issued and remain outstanding as a result of equity awards granted under the Plan. The Plan expires in May 2021.

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 endedJune 30, 2014 and 2013, we recorded $1.0 million and $1.4 million of stock-based compensation expense, respectively. For the six months endedJune 30, 2014 and 2013, we recorded $2.2 million and $2.8 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 endedJune 30, 2014 and 2013, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted stock was $1.9 million and $1.3 million, respectively.

Stock Options—We typically issue options that vest over three years in equal annual 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 endedJune 30, 2014 and 2013, 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 endedJune 30, 2014 and 2013:

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

Expected Term—The expected term of options granted to employees during the six months endedJune 30, 2014 and 2013 was determined from historical exercises of the grantee population. For all grants valued during the six months endedJune 30, 2014 and 2013, the options had graded vesting over three years in equal annual installments beginning on the first anniversary of the date of grant and a contractual term of five years.

14

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 endedJune 30, 2014 and 2013:

	Six months ended June 30,
	2014		2013
Volatility	29.88	%	32.45	%
Expected life of options	3 years		3 years
Risk-free interest rate	0.85	%	0.44	%
Dividend yield	3.00	%	3.00	%

Stock Option Activity—During the six months endedJune 30, 2014, we granted stock options to purchase 492,004 shares of Class A common stock at a weighted-average exercise price of $29.17 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the six months endedJune 30, 2014 and 2013, as determined under the Black-Scholes-Merton valuation model, was $4.90 and $4.81, respectively. These options vest over three years in equal annual installments beginning on the first anniversary of the date of the grant and have a contractual term of five years. Option grants that vested during the six months endedJune 30, 2014 and 2013 had a combined fair value of $2.6 million and $3.9 million, respectively.

The following table summarizes stock option activity for the year ended December 31, 2013 and the six months endedJune 30, 2014:

	Number of Shares		Weighted Average Exercise Price		Aggregate Intrinsic Value (in thousands)

The following table includes information concerning stock options exercisable and stock options expected to vest at June 30, 2014:

	Number of Shares	Weighted Average Remaining Contractual Life (years)	Weighted Average Exercise Price		Aggregate Intrinsic Value (in thousands)
Stock options exercisable	1,714,361	2.0	$	39.26	$	1,151
Stock options expected to vest	1,428,837	4.0	$	28.40	$	33,359
Stock options exercisable and expected to vest	3,143,198

Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2014 was $5.5 million, which is expected to be recognized over a weighted-average period of 1.9 years 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 shares issued to employees vest over three years in equal annual installments beginning on the first anniversary of the grant date, contingent upon employment with the Company on the vesting dates. Restricted shares issued to members of our Board of Directors vest 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.

Restricted Stock Activity—The following table summarizes the restricted stock activity during the year ended December 31, 2013 and the six months endedJune 30, 2014:

	Number of Shares		Grant Date Fair Value (in thousands)

11. Business Segment and Geographic Area Information

We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government. Our federal 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. The U.S. Army Tank-Automotive Armament Command (TACOM) contract accounted for 8.5% and 22.0% of our revenues and 7.0% and 15.7% of our operating income for the six months endedJune 30, 2014 and 2013, respectively. Revenues from the U.S. government under prime contracts and subcontracts were approximately 98.9% and 99.0% of our revenues for the six months endedJune 30, 2014 and 2013, respectively. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. Furthermore, substantially all of our assets from continuing operations were held in the United States for the three and six months endedJune 30, 2014 and year ended December 31, 2013.

12. Equity Method Investments

On May 24, 2012, Fluor-ManTech Logistics Solutions, LLC (FMLS), a limited liability company, was created with Fluor International, Inc. and ManTech as the investees. Each investee has a 50% ownership interest in FMLS. Because we have the ability to exercise significant influence over, but do not control, FMLS we determined that the equity method of accounting will be used for our investment. Under the operating agreement, we are required to provide additional financial support for losses incurred by FMLS. We recorded $65 thousand and $0 in equity method losses for the three months endedJune 30, 2014 and 2013, respectively. We recorded $122 thousand and $0 in equity method losses for the six months endedJune 30, 2014 and 2013, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties, many of which are outside of our control. ManTech International Corporation (depending on the circumstances, “ManTech,” “Company,” “we,” “our,” “ours” or “us”) believes these statements to be within the definition of the Private Securities Litigation Reform Act of 1995. You can identify these statements by forward-looking words such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “estimate” and other similar words. You should read statements that contain these words carefully because they discuss our future expectations, make projections of our future results of operations or financial condition or state other “forward-looking” information.

Although forward-looking statements in this Quarterly Report reflect our good faith judgment, such statements can only be based on facts and factors currently known by us. Consequently, forward-looking statements are inherently subject to risks and uncertainties, and actual results and outcomes may differ materially from the results and outcomes discussed in or anticipated by the forward-looking statements. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to predict accurately or control. Factors that could cause actual results to differ materially from the results we anticipate include, but are not limited to, the following:

• adverse changes or delays in U.S. government spending for programs we support due to cost cutting and efficiency initiatives, changing mission priorities or other federal budget constraints generally;

• uncertainty regarding the timing and nature of government action to complete the budget and appropriations process, continue federal government operations or address other budgetary constraints or other factors;

• failure to compete effectively for new contract awards or to retain existing U.S. government contracts;

• failure to obtain option awards, task orders or funding under contracts;

• delays in the competitive bidding process caused by competitors' protests of contract awards received by us or other factors;

• renegotiation, modification or termination of our contracts, or failure to perform in conformity with contract terms or our expectations;

• failure to realize the full amount of our backlog or adverse changes in the timing of receipt of revenues under contracts included in backlog;

• failure to successfully integrate acquired companies or businesses into our operations or to realize any accretive or synergistic effects from such acquisitions;

• failure to successfully identify and execute future acquisitions;

• adverse changes in business conditions that may cause our investments in recorded goodwill to become impaired;

• non-compliance with, or adverse changes in, complex U.S. government procurement laws, regulations or processes;

• failure to maintain strong relationships with other contractors;

• adverse results of U.S. government audits or other investigations of our government contracts; and

• disruption of our business or damage to our reputation resulting from security breaches in customer systems, internal systems or service failures (including as a result of cyber or other security threats), or employee or subcontractor misconduct.

We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report. These and other risk factors are more fully described and discussed in the section titled “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and under Item 1A. of Part II of our Quarterly Reports on Form 10-Q, and from time to time, in our other filings with the Securities and Exchange Commission (SEC). We undertake no obligation to revise or update any forward-looking statements in order to reflect any event or circumstance that may arise after the date of this Quarterly Report. We also suggest that you carefully review and consider the various disclosures made in this Quarterly Report that attempt to advise interested parties of the risks and factors that may affect our business, financial condition, results of operations and prospects.

Introduction and Overview

ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Energy and Justice, including the Federal Bureau of Investigations (FBI); the healthcare and space communities; and other U.S. federal 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, intelligence and homeland security. Over the past two 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 awards and spending. In addition, as U.S. forces have withdrawn from Afghanistan, revenues from our contracts in support of Overseas Contingency Operations (OCO) have substantially declined. The delays in awards from 2013 and the first half of 2014 have had continued impacts in 2014. Despite uncertainties over the past two years, we believe we are well positioned to meet our customers' needs and grow our business as we move through 2014 and beyond.

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, 2013, previously filed with the SEC.

Revenues

The primary driver of our decrease in revenues relates to reduced demand for services supporting Overseas Contingency Operations (OCO) as a result of the withdrawal of U.S. forces and reduction in military operations in Afghanistan. The reduction in our OCO related work in 2014 as compared to the same period in 2013 was primarily due to reduced demand on a sustainment contract for Mine-Resistance Ambush-Protected (MRAP) vehicles and reduced demand for field service support on C4ISR systems.

Cost of services

The decrease in cost of services was primarily due to reductions in revenues. As a percentage of revenues, direct labor costs were 42.8% for the three months endedJune 30, 2014, compared to 38.2% for the same period in 2013. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, were 43.5% for the three months endedJune 30, 2014, compared to 48.2% for the same period in 2013.

General and administrative expenses

The decrease in general and administrative expenses was due to cost reduction measures as well as certain cost being classified as cost of services instead of general and administrative expenses in 2014. We classify indirect costs in a manner consistent with disclosure statements filed with and approved by the Defense Contract Management Agency. Effective January 1, 2014, updates to our disclosure statements resulted in changes to the presentation of certain costs. Changes such as these do not impact the overall expense incurred or operating income and are presented prospectively. While overall general and administrative expenses decreased, general and administrative expenses as a percentage of revenues increased for the three months endedJune 30, 2014 when compared to the same period in 2013, largely due to the decline in revenues relative to levels of indirect spending.

Loss on extinguishment of debt

On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million for the three months endedJune 30, 2014.

Interest expense

The decrease in interest expense was primarily due to the redemption of the 7.25% senior unsecured notes on April 15, 2014, which resulted in 15 days of interest expense during the three months endedJune 30, 2014, compared to 90 days during the three months endedJune 30, 2013.

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. 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 40.1% and 37.8% for the three months endedJune 30, 2014 and 2013, respectively. The increase in the effective tax rate is attributable to 2013 tax credits that are no longer available in 2014 and a tax basis deduction on an investment taken in 2013.

Equity in losses of unconsolidated subsidiaries

We account for our investment in the Fluor-ManTech Logistics Solutions, LLC under the equity method of accounting. We recorded$0.1 millionand$0in equity method losses for thethree months endedJune 30, 2014 and 2013, respectively.

Net income

The decrease in net income was due to the reduction in revenues and margin pressure due to the competitive marketplace, loss on the extinguishment of debt, and investments the company is making in strategic initiatives.

Revenues

The primary driver of our decrease in revenues relates to reduced demand for services supporting Overseas Contingency Operations (OCO) as a result of the withdrawal of U.S. forces and reduction in military operations in Afghanistan. The reduction in our OCO related work in 2014 as compared to the same period in 2013 was primarily due to reduced demand on a sustainment contract for Mine-Resistance Ambush-Protected (MRAP) vehicles and reduced demand for field service support on C4ISR systems. In addition, we had a surge in equipment deliveries in the first quarter of 2013 on a contract for IT infrastructure modernization in the intelligence area. We expect the withdrawal from Afghanistan to continue to negatively impact revenues related to our contracts that support OCO during the remainder of 2014.

Cost of services

The decrease in cost of services was primarily due to lower revenues. As a percentage of revenues, direct labor costs were 43.3% for the six months endedJune 30, 2014, compared to 36.9% for the same period in 2013, which was primarily due to the decrease in other direct costs on OCO related contracts and fewer deliveries of equipment on an intelligence contract. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, was 43.3% for the six months endedJune 30, 2014, compared to 49.8% for the same period in 2013 due to a reduction in other direct costs on our OCO related contracts. We expect cost of services as a percentage of revenues to remain relatively stable for the remainder of the year.

General and administrative expenses

The decrease in general and administrative expenses was due to cost reduction measures as well as certain cost being classified as cost of services instead of general and administrative expenses in 2014. We classify indirect costs in a manner consistent with disclosure statements filed with and approved by the Defense Contract Management Agency. Effective January 1, 2014, updates to our disclosure statements resulted in changes to the presentation of certain costs. Changes such as these do not impact the

21

overall expense incurred or operating income and are presented prospectively. While overall general and administrative expenses decreased, general and administrative expenses as a percentage of revenues, increased for the six months endedJune 30, 2014 when compared to the same period in 2013, largely due to the decline in revenues relative to levels of indirect spending. We expect general and administrative expenses as a percentage of revenues to remain relatively stable for the remainder of the year.

Loss on extinguishment of debt

On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million for the six months endedJune 30, 2014.

Interest expense

The decrease in interest expense was primarily due to the redemption of the 7.25% senior unsecured notes on April 15, 2014. We expect interest expense to decrease for the remainder of the year.

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. 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 39.9% and 37.8% for the six months endedJune 30, 2014 and 2013, respectively. The increase in the effective tax rate is attributable to 2013 tax credits that are no longer available in 2014 and a tax basis deduction on investment taken in 2013. We expect the effective tax rate to decrease for the remainder of the year.

Equity in losses of unconsolidated subsidiaries

We account for our investment in the Fluor-ManTech Logistics Solutions, LLC under the equity method of accounting. We recorded$0.1 millionand$0in equity method losses for thesix months endedJune 30, 2014 and 2013, respectively. We expect the equity in losses of unconsolidated subsidiaries to remain stable for the remainder of the year.

Net income

The decrease in net income was due to the reduction in revenues and margin pressure due to the competitive market place, loss on extinguishment of debt, and investments the company is making in strategic initiatives. While the loss on extinguishment of debt was a one-time event, we expect the competitive marketplace and budgetary constraints of our customers to continue to adversely impact net income.

Backlog

At June 30, 2014 and December 31, 2013, our backlog was $3.8 billion and $3.9 billion, respectively, of which $1.0 billion and $1.1 billion, respectively, was funded backlog. 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, 2013, 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, 2014, the Company's cash and cash equivalents balance was $30.7 million. There were outstanding borrowings of $55.0 million under our revolving credit facility at June 30, 2014. At June 30, 2014, we were contingently liable under letters of credit totaling $0.8 million, which reduced our ability to borrow under our revolving credit facility by that amount. The maximum available borrowing under our revolving credit facility at June 30, 2014 was $444.2 million. On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. For additional information concerning our revolving credit facility and 7.25% senior unsecured notes, see Note 8 to our consolidated financial statements in Item 1.

22

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 is necessary from time to time to borrow 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 79 and 76 as of June 30, 2014 and 2013, respectively. For the six months endedJune 30, 2014 and 2013, our net cash flows from operating activities were $60.0 million and $89.1 million, respectively. The decrease in net cash flows from operating activities during the six months endedJune 30, 2014 when compared to the same period in 2013 was primarily due to lower net income.

Cash Flows from Investing Activities

Our cash flows from investing activities consist primarily of business combinations, purchases of property and equipment and investments in capitalized software for internal use. For the six months endedJune 30, 2014 and 2013, our net cash outflows from investing activities were $130.0 million and $15.8 million, respectively. During the six months endedJune 30, 2014, our net cash outflows from investing activities were primarily due to the acquisitions of 7Delta Inc. and Allied Technology Group, Inc. in addition to our investments in capitalized software for internal use. During the six months endedJune 30, 2013, our net cash outflows from investing activities were primarily due to the acquisition of ALTA Systems, Inc. and capital expenditures.

Cash Flows from Financing Activities

For the six months endedJune 30, 2014 and 2013, our net cash outflows from financing activities were $168.3 million and $14.7 million, respectively. During the six months endedJune 30, 2014, our net cash outflows from financing activities resulted primarily from repayments of our 7.25% senior unsecured notes and dividends paid, partially offset by borrowings under our revolving credit facility, net of repayments. During thesix months endedJune 30, 2013, our net cash outflows from financing activities resulted primarily from dividends paid.

Capital Resources

We believe the capital resources available to us from cash on hand of $30.7 million at June 30, 2014, the $500.0 million available under our 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 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 borrowing or issuance of debt or 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 under our revolving credit facility bear interest at one of the following variable rates as selected by the Company at the time of the borrowing: a LIBOR based rate plus market spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's 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 endedJune 30, 2014 and 2013, we declared and paid two dividends in the amount of $0.21 per share on both classes of 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.

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 accounting principles generally accepted in the United States of America. 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 accounting policies and practices listed below, are more fully described and discussed in the notes to the consolidated financial statements for the fiscal year 2013 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, filed with the SEC on February 21, 2014.

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 or time-and-materials contracts. Revenues for cost reimbursement 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-material contracts, revenues are recognized to the extent of billable rates times hours delivered plus material 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 is 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 ASC 605-35, 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 revenue 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. Both the individual changes in contract estimates and aggregate net changes in the contract estimates recognized using the cumulative catch-up method of accounting were not material to the consolidated statement of operations for all periods presented. 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.

24

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 have elected to perform this review during the second quarter of each calendar year. An entity may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (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 the 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 actual arm's length transactions. 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 provided 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, which we then compare to the control premiums in comparable transactions to assess the reasonableness of our calculations.

We have elected to perform our annual review during the second 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 of 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 goodwill, differences in assumptions may have a material effect on the results of our goodwill impairment analysis.

Accounting Standards Updates

On May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including Accounting Standards Codification (ASC) No. 605-35,  Revenue Recognition - Construction-Type and Production-Type Contracts.  ASU 2014-09 outlines a single set of comprehensive principles for recognizing revenue under U.S. 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 will be effective January 1, 2017, and may be applied either retrospectively or through the use of a modified-retrospective method. We are currently evaluating both methods of adoption as well as the effect ASU 2014-09 will have on our consolidated financial statements.

Other accounting standards updates effective after June 30, 2014, are not expected to have a material effect on the company’s consolidated financial position or its annual results of operations and cash flows.

25

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risks relates to changes in interest rates for borrowing under our revolving credit facility. The outstanding balance on our revolving credit facility was $55.0 million at June 30, 2014. Borrowings under our revolving credit facility bear interest at variable rates. A hypothetical 10% increase in interest rates would have increased our interest expense by $6 thousand for the six months endedJune 30, 2014.

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, 2014, 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 the Company’s 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 Auditing Agency. In addition to these routine audits, we are subject from time to time to audits and investigations by other agencies of the federal 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 federal government or a particular agency, or civil or criminal proceedings seeking penalties and/or fines. Audits and investigations conducted by the federal 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, operating results or cash flows.

Acquisitions

7Delta Inc.—On May 23, 2014, we completed the acquisition of all equity interests in 7Delta Inc. (7Delta). The results of 7Delta's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an amended and restated stock purchase agreement dated May 23, 2014, by and among ManTech International Corporation, 7Delta, SLS Holdings, Inc. and the stockholders of SLS Holdings, Inc. 7Delta performs critical services such as applications and software development, program management, systems integration, information assurance and security architecture primarily within the healthcare community at the Department of Veteran Affairs (VA). We funded the acquisition through a combination of cash on hand and borrowings under our revolving credit facility. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2014, ManTech incurred approximately $0.6 million of acquisition costs related to the 7Delta transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The preliminary purchase price of $80.0 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The preliminary purchase price may increase or decrease depending on the completion of the working capital adjustment. We are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price and the determination of the fair value of the assets acquired and liabilities assumed. We preliminarily recorded goodwill of $69.6 million, which 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 7Delta's capabilities in providing software development, program management, system integration, information assurance and security architecture to the VA.

In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of 7Delta's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $4.8 million and $2.9 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with 7Delta's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 10 years. Backlog is amortized straight-line over its estimated useful life of 2 years. The weighted-average amortization period for the intangible assets is 7.0 years.

We have not disclosed current period, nor pro forma, revenues and earnings attributable to 7Delta as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable.

Allied Technology Group, Inc.—On February 18, 2014, we completed the acquisition of all equity interests in Allied Technology Group, Inc. (ATG). The results of ATG's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 18, 2014, by and among ManTech Advanced Systems International, Inc., Allied Technology Group, Inc. and the stockholders of ATG. ATG is an innovative engineering and information management solution company with strong customer relationships and strategic contracts with the Department of Homeland Security (DHS). ATG provides IT, engineering services, program management and training solutions to a variety of federal customers. The acquisition will enable us to deliver services through their unrestricted prime position on DHS's primary acquisition vehicles: Technical, Acquisition and Business Support Services and Enterprise Acquisition Gateway for Leading Edge Solutions II. We funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2014, ManTech incurred approximately $0.4 million of acquisition costs related to the ATG transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The purchase price of $45.0 million was preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We are still evaluating the fair value of assets acquired and liabilities assumed. We preliminarily recorded goodwill of $28.4 million, which 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 ATG's capabilities in providing technology service program management, systems engineering and information technology services to DHS.

In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ATG's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $6.4 million and $0.6 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ATG's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life 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 18.4 years.

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

The following table represents the preliminary purchase price allocation for 7Delta and ATG (in thousands):

	7Delta Inc.			Allied Technology Group, Inc.

ALTA Systems, Inc.—On January 8, 2013, we completed the acquisition of all equity interests in ALTA Systems, Inc. (ALTA). The results of ALTA's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated January 8, 2013, by and among ManTech International Corporation, ALTA Holdings LLC and the sole member of ALTA Holdings LLC. ALTA is an information technology (IT) and professional services company with valuable applications in healthcare systems and capital planning. ALTA provides a broad range of IT and professional services to government and private industry in three major areas: capital planning and investment control; system design, development and operations; and fraud detection and statistical analysis. The acquisition allows ManTech to deliver technology services through ALTA's prime position on the Centers for Medicare and Medicaid Services (CMS) Enterprise Systems Development (ESD) contract. ManTech funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.

During the six months endedJune 30, 2013, ManTech incurred approximately $0.1 million of acquisition costs related to the ALTA transaction, which are included in the general and administrative expenses in our consolidated statement of income.

The purchase price of $10.2 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We have recorded total assets of $11.1 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities of $0.9 million. Included in total assets were $0.7 million in acquisition related intangible assets. We recorded goodwill of $9.1 million, which 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 ALTA's capabilities in providing technology services to the federal government in the health care sector.

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ALTA's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $0.6 million and $0.1 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ALTA's existing customers. Customer relationships and backlog are amortized straight-line over their estimated useful lives of approximately 20 years and 1 year, respectively. The weighted-average amortization period for the intangible assets is 17.1 years.

Basis of Presentation [Text Block]

Basis of Presentation

The accompanying unaudited 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 United States of America, have been condensed or omitted pursuant to those rules and regulations. We recommend that you read these unaudited 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, 2013, previously filed with the SEC. We believe that the unaudited 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 classify indirect cost incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2014, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2014 as compared to 2013; however, total operating costs were not affected by this change.

Business Segment and Geographic Area Information [Text Block]

Business Segment and Geographic Area Information

We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government. Our federal 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. The U.S. Army Tank-Automotive Armament Command (TACOM) contract accounted for 8.5% and 22.0% of our revenues and 7.0% and 15.7% of our operating income for the six months endedJune 30, 2014 and 2013, respectively. Revenues from the U.S. government under prime contracts and subcontracts were approximately 98.9% and 99.0% of our revenues for the six months endedJune 30, 2014 and 2013, respectively. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. Furthermore, substantially all of our assets from continuing operations were held in the United States for the three and six months endedJune 30, 2014 and year ended December 31, 2013.

Revenues by geographic customer and the related percentages for the three and six months endedJune 30, 2014 and 2013 were as follows (dollars in thousands):

Equity Method Investments

On May 24, 2012, Fluor-ManTech Logistics Solutions, LLC (FMLS), a limited liability company, was created with Fluor International, Inc. and ManTech as the investees. Each investee has a 50% ownership interest in FMLS. Because we have the ability to exercise significant influence over, but do not control, FMLS we determined that the equity method of accounting will be used for our investment. Under the operating agreement, we are required to provide additional financial support for losses incurred by FMLS. We recorded $65 thousand and $0 in equity method losses for the three months endedJune 30, 2014 and 2013, respectively. We recorded $122 thousand and $0 in equity method losses for the six months endedJune 30, 2014 and 2013, respectively.

Allowance for doubtful accounts	(10,497		)	(10,036		)
Receivables-net	$	408,063		$	457,898

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. There is a contract with the U.S. Army that represents 10.9% and 15.3% of receivables-net at June 30, 2014 and December 31, 2013, respectively. Accounts receivable at June 30, 2014, are expected to be substantially collected within one year except for approximately $1.4 million, of which amount 91.1% is related to receivables from direct 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 the Company’s exposure to compliance issues, contractual issues and bad debt related to prime contractors.

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 the Company’s 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 the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayment, 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. We have settled all incurred cost submissions through 2005 with the Defense Contract Management Agency (DCMA) Corporate Administrative Contracting Officer (CACO). Settlements of the 2006 through 2013 incurred cost submission 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.

Goodwill and Other Intangible Assets

Under ASC 350, Intangibles—Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. We have elected to perform this review during the second quarter of each calendar year. An entity may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (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 the 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 actual arm's length transactions. 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 provided 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, which we then compare to the control premiums in comparable transactions to assess the reasonableness of our calculations.

During the second quarter of 2014, we completed our annual goodwill impairment test. The results of this test indicated that the fair values of all reporting units were substantially in excess of their carrying values, therefore, no impairment losses were identified and performance of step two was not required. We continue to monitor events that could impact our financial outlook and our assets including potential significant reductions in government spending that could adversely impact our financial results and changes in market conditions that could result in a reduction in the fair value of our assets.

The changes in the carrying amounts of goodwill during the year ended December 31, 2013 and the period ended June 30, 2014 are as follows (in thousands):

Debt Disclosure [Abstract]

Debt Disclosure [Text Block]

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 $25 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. On June 13, 2014, we amended and restated the credit agreement, and extended the maturity date to June 13, 2019. We deferred $3.4 million in debt issuance costs, which are amortized over the term of the amended and restated 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 (LIBOR) base rate plus market-rate spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's 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, 2014, we were in compliance with the financial covenants under the credit agreement.

The outstanding balance on our revolving credit facility at June 30, 2014 and December 31, 2013 was $55.0 million and $0, respectively. The outstanding debt balance at June 30, 2014 is estimated to be repaid by June 30, 2015. The maximum available borrowing under our revolving credit facility at June 30, 2014 was $444.2 million. As of June 30, 2014, we were contingently liable under letters of credit totaling $0.8 million, which reduced our availability to borrow under our revolving credit facility.

7.25% Senior Unsecured Notes—On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes issued on April 13, 2010 for $200.0 million, which were registered under the Securities Act of 1933. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million as non-operating income on our consolidated statement of income.

Share-based Compensation [Abstract]

Stock-Based Compensation [Text Block]

Stock-Based Compensation

Our 2011 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. 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 2, 2014, 557,894 additional shares were made available for issuance under the Plan. Through June 30, 2014, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 4,068,523. Through June 30, 2014, there were 4,707,168 shares of our Class A common stock that were issued and remain outstanding as a result of equity awards granted under the Plan. The Plan expires in May 2021.

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 endedJune 30, 2014 and 2013, we recorded $1.0 million and $1.4 million of stock-based compensation expense, respectively. For the six months endedJune 30, 2014 and 2013, we recorded $2.2 million and $2.8 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 endedJune 30, 2014 and 2013, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted stock was $1.9 million and $1.3 million, respectively.

Stock Options—We typically issue options that vest over three years in equal annual 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 endedJune 30, 2014 and 2013, 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 endedJune 30, 2014 and 2013:

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

Expected Term—The expected term of options granted to employees during the six months endedJune 30, 2014 and 2013 was determined from historical exercises of the grantee population. For all grants valued during the six months endedJune 30, 2014 and 2013, the options had graded vesting over three years in equal annual 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 endedJune 30, 2014 and 2013:

	Six months ended June 30,
	2014		2013
Volatility	29.88	%	32.45	%
Expected life of options	3 years		3 years
Risk-free interest rate	0.85	%	0.44	%
Dividend yield	3.00	%	3.00	%

Stock Option Activity—During the six months endedJune 30, 2014, we granted stock options to purchase 492,004 shares of Class A common stock at a weighted-average exercise price of $29.17 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the six months endedJune 30, 2014 and 2013, as determined under the Black-Scholes-Merton valuation model, was $4.90 and $4.81, respectively. These options vest over three years in equal annual installments beginning on the first anniversary of the date of the grant and have a contractual term of five years. Option grants that vested during the six months endedJune 30, 2014 and 2013 had a combined fair value of $2.6 million and $3.9 million, respectively.

The following table summarizes stock option activity for the year ended December 31, 2013 and the six months endedJune 30, 2014:

Stock options expected to vest	1,428,837	4.0	$	28.40	$	33,359
Stock options exercisable and expected to vest	3,143,198

Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2014 was $5.5 million, which is expected to be recognized over a weighted-average period of 1.9 years 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 shares issued to employees vest over three years in equal annual installments beginning on the first anniversary of the grant date, contingent upon employment with the Company on the vesting dates. Restricted shares issued to members of our Board of Directors vest 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.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings Per Share

Under 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 the Company’s 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 endedJune 30, 2014 and 2013, 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 common shares 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 has 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):

For the three months endedJune 30, 2014 and 2013, options to purchase 2.8 million and 3.3 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 endedJune 30, 2014 and 2013, options to purchase 2.8 million and 3.5 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 endedJune 30, 2014 and 2013, shares issued from the exercise of stock options were 53 thousand and 39 thousand, respectively.
