NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2019

UNAUDITED


1.	Description of the Business

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) provide mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies. In business more than 50 years, we excel in full-spectrum cyber, data collection & analytics, enterprise information technology (IT), systems and software engineering solutions that support national and homeland security.


2.	Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in the annual financial statements, prepared in accordance with accounting principles generally accepted in the U.S., have been condensed or omitted pursuant to those rules and regulations. The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. We recommend that you read these condensed consolidated financial statements in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 , previously filed with the SEC. We believe that the condensed consolidated financial statements in this Form 10-Q reflect all adjustments that are necessary to fairly present the financial position, results of operations and cash flows for the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results that can be expected for the full year.


3.	Revenue from Contracts with Customers

On January 1, 2018, we adopted Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers using the modified retrospective method applied to those contracts that were not substantially complete as of January 1, 2018. ASC 606 outlines a five-step model whereby revenue is recognized as performance obligations within the contract are satisfied. ASC 606 also requires new, expanded disclosures regarding revenue recognition. We recognized the cumulative effect of adopting ASC 606 as an increase to the 2018 opening balance of retained earnings in the amount of $0.8 million , with the impact primarily related to fixed-price contracts.

We derive revenue from contracts with customers primarily from contracts with the U.S. government in the areas of defense, intelligence, homeland security and other federal civilian agencies. Substantially all of our revenue is derived from services and solutions provided to the U.S. government or to prime contractors supporting the U.S. government, including services by our employees and our subcontractors, and solutions that include third-party hardware and software that we purchase and integrate as a part of our overall solutions. Customer requirements may vary from period-to-period depending on specific contract and customer requirements. We provide our services and solutions under three types of contracts: cost-reimbursable, fixed-price and time-and-materials. Under cost-reimbursable contracts, we are reimbursed for costs that are determined to be reasonable, allowable and allocable to the contract and paid a fee representing the profit margin negotiated between us and the contracting agency, which may be fixed or performance based. Under fixed-price contracts, we perform specific tasks for a fixed price. Fixed-price contracts may include either a product delivery or specific service performance over a defined period. Under time-and-materials contracts, we are reimbursed for labor at fixed hourly rates and generally reimbursed separately for allowable materials, costs and expenses at cost. We typically recognize revenue for time and material contracts under the "right to invoice" model.

For contracts that do not meet the criteria to measure performance as a right to invoice, or under the series guidance, we utilize an Estimate at Completion process to measure progress toward completion. We typically estimate progress towards completion based on cost incurred or direct labor incurred. As part of this process, we review information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenue and costs. The risks and opportunities include judgments about the ability and cost to achieve the contract milestones and other technical contract requirements. We make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer and overhead cost rates, among other variables. A significant change in one or more of these estimates could affect the timing in which we recognize revenue on our contracts. For the three months ended March 31, 2019 , the aggregate impact of adjustments in contract estimates increased our revenue by $3.2 million .

We have one reportable segment. Our U.S. government customers typically exercise independent decision-making and contracting authority. Offices or divisions within an agency or department of the U.S. government may directly, or through a prime contractor, use our services as a separate customer as long as the customer has independent decision-making and contracting authority within its organization. We treat sales to U.S. government customers as sales within the U.S. regardless of where the services are performed.

The following tables disclose revenue (in thousands) by contract type, customer, prime or subcontractor and geography for the periods presented.

Receivables at March 31, 2019 are expected to be substantially collected within one year except for approximately $0.9 million , of which 100% is related to receivables from sales to the U.S. government or from contracts in which we acted as a subcontractor to other contractors selling to the U.S. government. We have one contract which accounts for 11.4% of our accounts receivable balance. We do not believe that we have significant exposure to credit risk as billed receivable and unbilled receivables

are primarily due from the U.S. government. The allowance for doubtful accounts represents our estimate for exposure to compliance, contractual issues and bad debts related to prime contractors.

4.	Leases

The Financial Accounting Standards Board (FASB) issued ASC 842, Leases , to increase transparency and comparability among organizations by requiring the recognition of right of use (ROU) assets and lease liabilities on the balance sheet. Most prominent among the changes in ASC 842 is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. We are also required to recognize and measure leases existing at, or entered into after, the beginning of the earliest comparative period presented using a modified retrospective approach, with certain practical expedients available.

We elected to adopt ASC 842 on January 1, 2019, resulting in us recording operating lease liabilities of $129.6 million and operating lease right of use assets of $118.7 million . We elected the practical expedient to recognize the lease payments related to short-term leases as profit or loss on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payment is incurred. We also elected the following transition related practical expedients: not to reassess whether expired or existing contracts are or contain leases, not to reassess lease classification as determined under ASC 840 and not to reassess initial direct costs from any existing lease. We also elected the practical expedient as an accounting election not to separate nonlease components from lease components on all classes of underlying assets. Our leases include nonlease components such as common area maintenance (CAM), utilities and operating expenses. We also implemented internal controls and key system functionality to enable the preparation of financial information upon adoption. ASC 842 had a material impact on our condensed consolidated balance sheets, but did not have an impact on our condensed consolidated income statements. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged.

We determine if a contract is or contains a lease at inception. A contract is or contains a lease if the contract conveys the right to control the use of identified property or equipment (an identified asset) for a period of time in exchange for consideration. We have the right to control the use of the identified asset when we have both of the following: the right to obtain substantially all of the economic benefits from use of the identified asset and the right to direct the use of the identified asset. In making this determination, we consider all relevant facts and circumstances. We reassess whether a contract is or contains a lease only if the terms and conditions of the contract are changed. We account for lease components and nonlease components associated with a lease as a single lease component. Operating leases are included in Operating lease ROU assets, Operating lease liabilities—current and Operating lease liabilities—long term on our condensed consolidated balance sheets. Finance leases are included in Property and equipment—net, Accounts payable and other accrued expenses and Other long-term liabilities on our condensed consolidated balance sheets.

guarantees. Our variable lease payments are excluded in measuring ROU asset and lease liability because they do not depend on an index or a rate or are not in substance fixed payments. We exclude lease incentives and initial direct cost incurred from our lease payments. Our leases typically do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments.

For operating leases, after lease commencement, we measure our lease liability for each period at the present value of any remaining lease payments, discounted by using the rate determined at lease commencement. In our condensed consolidated statement of income, we recognize a single operating lease expense calculated on a straight-line basis over the remaining lease term. The amortization of the ROU asset increases each year as a result of the declining lease liability balance. Variable lease payments are not recognized in the measurement of the lease liability - they are recognized in the period in which the related obligation has been incurred.

For finance leases, after lease commencement, we measure our lease liability by using the effective interest rate method. In each period, the lease liability will be increased to reflect the interest that is accrued on the related lease liability by using the appropriate discount rate, offset by a decrease in the lease liability resulting from the periodic lease payments. We recognize the ROU asset at cost, reduced by any accumulated depreciation. The ROU asset is depreciated on a straight-line basis. Together, the interest expense and amortization expense result in a front-loaded expense profile. We will present interest expense and depreciation expense separately on our condensed consolidated statement of income.

We have operating and finance leases for real estate, transportation vehicles and equipment. Our variable lease payments do not depend on an index or a rate or are not in substance fixed payments. Our leases have remaining lease terms of 0.1 years to 11 years , some of which include options to extend the leases for up to 14 years , and some of which include options to terminate the leases within 1 year . Our transportation vehicles and equipment leases include a residual value guarantee, which is a guarantee made to the lessor that the value of the underlying asset returned to the lessor at the end of the lease will be at least a specific amount. We sublease some of our real estate lease space, resulting in sublease income of $23 thousand as of the three months ended March 31, 2019 . We do not have any leases that have not yet commenced due to construction or design of the underlying asset. We recognize payments related to short-term leases (less than one year) as profit or loss on a straight-line basis over the lease term and variable leases payments in the period in which the obligation for those payment is incurred. As such, our short-term lease expense as of March 31, 2019 under ASC 842 was $1.4 million . For the three months ended March 31, 2019 , we incurred variable lease costs of $0.5 million .

5.	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 our Certificate of Incorporation, the holders of the common stock are entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends as may be declared by the Board of Directors. During the three months ended March 31, 2019 and 2018 , we declared and paid quarterly dividends in the amount of $0.27 per share and $0.25 per share, respectively, on both classes of common stock.

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

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



	Three months ended March 31,
	2019		2018
Distributed earnings	$	10,749	$	9,867
Undistributed earnings	10,369		10,200
Net income	$	21,118	$	20,067

Class A common stock:
Basic net income available to common stockholders	$	14,116	$	13,333
Basic weighted average common shares outstanding	26,584		26,115
Basic earnings per share	$	0.53	$	0.51

Diluted net income available to common stockholders	$	14,157	$	13,403
Effect of potential exercise of stock options	235		410
Diluted weighted average common shares outstanding	26,819		26,525
Diluted earnings per share	$	0.53	$	0.51

Class B common stock:
Basic net income available to common stockholders	$	7,002	$	6,734
Basic weighted average common shares outstanding	13,188		13,189
Basic earnings per share	$	0.53	$	0.51

Diluted net income available to common stockholders	$	6,961	$	6,664
Diluted weighted average common shares outstanding	13,188		13,189
Diluted earnings per share	$	0.53	$	0.51

For the three months ended March 31, 2019 and 2018 , options to purchase 514,224 shares and 310,745 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 three months ended March 31, 2019 and 2018 , there were 51,089 shares and 203,854 shares, respectively, issued from the exercise of stock options. For the three months ended March 31, 2019 and 2018 there were 72,188 shares and 86,233 shares issued from the vesting of restricted stock units.


6.	Property and Equipment

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



	March 31, 2019			December 31, 2018
Furniture and equipment	$	105,934		$	97,577
Leasehold improvements	43,529			43,065

Accumulated depreciation and amortization	(95,488		)	(89,215		)
Property and equipment—net	$	54,479		$	51,427

Depreciation and amortization expense related to property and equipment for the three months ended March 31, 2019 and 2018 was $6.3 million and $5.9 million , respectively.


7.	Goodwill and Other Intangible Assets

There was no change in the carrying amount of goodwill during the three months ended March 31, 2019 . The change in the carrying amount of goodwill during the year ended December 31, 2018 is as follows (in thousands):



	Goodwill Balance
Goodwill at December 31, 2017	$	1,084,560
Acquisition fair value adjustment	1,246
Goodwill at December 31, 2018	$	1,085,806

Amortization expense relating to intangible assets for the three months ended March 31, 2019 and 2018 was $5.8 million and $7.1 million . We estimate that we will have the following amortization expense for the future periods indicated below (in thousands):



For the remaining nine months ending December 31, 2019	$	16,814
For the year ending:
December 31, 2020	$	21,758
December 31, 2021	$	19,028
December 31, 2022	$	16,434
December 31, 2023	$	13,464
December 31, 2024	$	12,199


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 $75 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments. The maturity date is August 17, 2022 .

Borrowings under our credit agreement are collateralized by substantially all of our assets and those of our Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: a London Interbank Offer Rate based rate plus market-rate spreads ( 1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads ( 0.25% to 1.25% based on our consolidated total leverage ratio).

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires us 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 maintaining 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 and during the three months ended March 31, 2019 and 2018 , we were in compliance with the financial covenants under the credit agreement.

There was $96.0 million and $7.5 million outstanding on our revolving credit facility at March 31, 2019 and December 31, 2018 , respectively. The maximum available borrowing under the revolving credit facility at March 31, 2019 was $396.3 million . As of March 31, 2019 , we were contingently liable under letters of credit totaling $7.7 million , which reduces our availability to borrow under our revolving credit facility.


9.	Commitments and Contingencies

Contracts with the U.S. government, including subcontracts, are subject to extensive legal and regulatory requirements and, from time-to-time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of us, whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil or criminal liabilities, including repayments, fines or penalties being imposed upon us, or could lead to suspension or debarment from future U.S. government contracting activities. Management believes it has adequately reserved for any losses that may be experienced from any investigation of which it is aware. The Defense Contract Audit Agency has substantially completed our incurred cost audits through 2016 with no material adjustments. The remaining audits for 2017 through 2018 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, except for the matter noted below.

An officer of our Company is a party to a pending arbitration proceeding with a former employer that relates to certain breach of contract claims. Pursuant to indemnification arrangements we have with this officer, we may be exposed to a potential loss related to this claim. Pursuant to applicable accounting standards, we have determined that it is reasonably possible that an unfavorable outcome could cause us to incur a liability/loss under these indemnification arrangements. However, given the nature of the claim, the early stage of the process, the limitations on information and other factual details relating to the claims that are available to us at this time, and management’s intent to contest the matter vigorously, we are unable to make a reasonable estimate of loss at this time. As such, we have not disclosed an amount of potential loss as of March 31, 2019 .

We have $7.7 million outstanding on our letter of credit, of which $14 thousand is related to an outstanding performance bond in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company to fulfill technical support requirements for the Royal Saudi Air Force.


10.	Stock-Based Compensation

Our 2016 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. The types of awards available under the Plan include, among others, stock options, restricted stock and restricted stock units (RSUs). Equity awards granted under the Plan are settled in shares of Class A common stock. At the beginning of each year, the Plan provides that the number of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and Class B common stock outstanding on December 31 ^st of the previous year. On January 2, 2019 , there were 596,422 additional shares made available for issuance under the Plan. Through March 31, 2019 , the Board of Directors has authorized the issuance of up to 15,148,321 shares under this Plan. Through March 31, 2019 , the remaining aggregate number of shares of our common stock available for future grants under the Plan was 6,685,056 . The Plan expires in March 2026 .

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

Stock Compensation Expense —For the three months ended March 31, 2019 and 2018 , we recorded $1.3 million and $1.1 million of stock-based compensation expense. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the three months ended March 31, 2019 and 2018 , we recorded $0.2 million and $1.1 million , respectively, to income tax benefit related to the exercise of stock options, vested cancellations and the vesting of restricted stock.

Stock Options —Under the Plan, we have issued stock options. A stock option gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined price for a specific period of time. We typically issue options that vest over three years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plan, the

contractual life of the option grants may not exceed eight years . During the three months ended March 31, 2019 and 2018 , 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 the 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 three months ended March 31, 2019 and 2018 :


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


•	Expected life of options —The expected life of options granted to employees was determined from historical exercises of the grantee population. The options had graded vesting over three years in equal installments beginning on the first anniversary of the date of grant and a contractual term of five years .


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


•	Dividend Yield —The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. We have calculated our expected dividend yield based on an expected annual cash dividend of $1.08 per share.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the three months ended March 31, 2019 and 2018 :



	Three months ended March 31,
	2019		2018
Volatility	26.99	%	26.34	%
Expected life of options	3 years		3 years
Risk-free interest rate	2.39	%	2.46	%
Dividend yield	2.00	%	2.00	%

Stock Option Activity —The weighted-average fair value of options granted during the three months ended March 31, 2019 and 2018 , as determined under the Black-Scholes-Merton valuation model, was $10.04 and $9.96 , respectively. Option grants that vested during the three months ended March 31, 2019 and 2018 had a combined fair value of $1.2 million and $0.7 million , respectively.

The following table summarizes stock option activity for the year ended December 31, 2018 and the three months ended March 31, 2019 :



	Number of Shares		Weighted Average Exercise Price		Aggregate Intrinsic Value (in thousands)		Weighted Average Remaining Contractual Life
Stock options outstanding at December 31, 2017	1,169,408		$	35.88	$	16,731

The following table summarizes non-vested stock options for the three months ended March 31, 2019 :



	Number of Shares		Weighted Average Fair Value
Non-vested stock options at December 31, 2018	774,402		$	8.77
Granted	250,231		$	10.04
Vested	(157,473	)	$	7.38
Cancelled	(19,415	)	$	8.95
Non-vested stock options at March 31, 2019	847,745		$	9.40

Unrecognized compensation expense related to non-vested awards was $7.3 million as of March 31, 2019 , which is expected to be recognized over a weighted-average period of 2 years .

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

Restricted Stock Activity — There was no restricted stock activity during the three months ended March 31, 2019 . The following table summarizes the restricted stock activity during the year ended December 31, 2018 .



	Number of Shares		Weighted Average Fair Value
Non-vested restricted stock at December 31, 2017	24,000		$	37.90
Granted	24,000		$	52.83
Vested	(28,000	)	$	40.03
Non-vested restricted stock at December 31, 2018	20,000		$	52.83

RSUs —Under the Plan, we have issued RSUs. RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and have no voting rights until the RSUs vest. Employees who are granted RSUs do not receive dividend payments during the vesting period. Our employees have been granted performance-based RSUs and time-based RSUs. Performance-based RSUs result in the delivery of shares only if (a) performance criteria is met and (b) the employee remains employed, in good standing, through the date of the performance period.

Time-based RSUs vest in one-third increments on the first, second and third anniversaries of the date of grant. The grant date fair value of the RSUs is equal to the closing market price of our common stock on the grant date less the present value of dividends expected to be awarded during the service period. We recognize the grant date fair value of RSUs of shares we expect to issue as compensation expense ratably over the requisite service period.

RSU Activity —For performance-based RSUs that vested in 2019 and 2018 , each RSU awarded resulted in the issuance of 1.5 shares, which were issued net of applicable payroll tax withholdings. The following table summarizes the non-vested RSU activity during the year ended December 31, 2018 and the three months ended March 31, 2019 :



	Number of Units		Weighted Average Fair Value
Non-vested RSUs at December 31, 2017	161,343		$	31.36
Granted	76,713		$	53.97
Vested	(87,200	)	$	28.40

We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report. We undertake no obligation to update any forward-looking statement made herein following the date of this Quarterly Report, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

Overview

We provide mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies. We excel in full-spectrum cyber, data collection & analytics, enterprise information technology (IT), systems and software engineering solutions that support national and homeland security.

As of February 15, 2019, all agencies of the U.S. federal government have funding through appropriations through Government fiscal year (GFY) 2019. Approximately 75% of the U.S. government including the Department of Defense had full year appropriations to begin the fiscal year. Appropriations for the Department of Defense include near term expansions that aligned with the Administration's stated priorities in dealing with significant global threats, readiness and force structure needs within the military, diplomatic, and cyber aggressions by both state and non-state actors. A number of federal civilian agencies, including the Departments of Homeland Security and State operated under a Continuing Resolution through late December and then endured a 35-day lapse in funding prior to receiving appropriations in mid-February. We expect future appropriations to be debated with the consideration of policy priorities, national budget deficits, debt ceilings and the Budget Control Act.

We recommend that you read this discussion and analysis in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 , previously filed with the Securities and Exchange Commission.

Three Months Ended March 31, 2019 Compared to the Three Months Ended March 31, 2018

The following table sets forth certain items from our condensed consolidated statements of income and the relative percentage that certain items of expenses and earnings bear to revenue, as well as the period-to-period change from March 31, 2018 to March 31, 2019 .

Revenue

The primary driver of our increase in revenues relates to revenue from new contract awards and growth on certain existing contracts, which were offset by contracts and tasks that ended and reduced scope of work on some contracts.

Cost of services

The increase in cost of services was primarily due to increases in revenue. As a percentage of revenue, direct labor costs were 48% for both the three months ended March 31, 2019 and 2018 . 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 38% for the three months ended March 31, 2019 , compared to 37% for the same period in 2018 .

General and administrative expenses

The decrease in general and administrative expenses was primarily due to reduced bid and proposal spending and amortization of acquisition intangibles offset by increased spending on infrastructure. We expect general and administrative expenses as a percent of revenue to increase during the remainder of 2019 due to the acquisition of Kforce Government Solutions (KGS) and increased bid and proposal spending.

Interest expense

The decrease in interest expense was due to repayment of debt on our revolving line of credit. We expect interest expense to increase for the remainder of 2019 due to increased borrowings under our credit facility to fund the acquisition of KGS. For additional information, see Note 11 in our condensed consolidated financial statements in Item 1.

Provision for income taxes

Our effective tax rate is affected by recurring items, such as the relative amount of income we earn in various taxing jurisdictions and their tax rates. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rates were 25% and 22% for the three months ended March 31, 2019 and 2018 , respectively. The primary driver of the increase in our effective tax rate was due to a reduction in the tax benefit related to stock-based compensation.

Backlog

Backlog represents estimates that we calculate on a consistent basis. We define backlog as our estimates of the remaining revenue from existing signed contracts, assuming the exercise of all options relating to such contracts and including executed task orders issued under Indefinite Delivery/Indefinite Quantity contracts.

We define funded backlog to be the portion of backlog for which funding currently is appropriated and allocated to the contract by the purchasing agency or otherwise authorized for payment by the customer upon completion of a specific portion of work. Our funded backlog does not include the full value of our contracts because Congress often appropriates funds for a particular program or contract on a yearly or quarterly basis, even though the contract may call for performance over a much longer period of time.

A variety of circumstances or events may cause changes in the amount of our backlog and funded backlog, including the execution of new contracts, the extension of existing contracts, the non-renewal or completion of current contracts, the early termination of contracts and adjustment to estimates for previously included contracts. Changes in the amount of our funded backlog also are affected by the funding cycles of the U.S. government.

At both March 31, 2019 and December 31, 2018 , our backlog was $8.4 billion . Our funded backlog was $1.5 billion and $1.3 billion as of March 31, 2019 and December 31, 2018 .

The following table reconciles our backlog to our remaining performance obligations as disclosed in Note 3 to our condensed consolidated financial statements in Item 1 (in billions):



	March 31, 2019
Backlog	$	8.4
Unexercised contract options	5.7
Remaining performance obligation	$	2.7

Liquidity and Capital Resources

Our primary liquidity needs relate to managing working capital, financing acquisitions, making cash dividend payments, purchasing property and equipment and investing in capital software. Our primary sources of liquidity are cash from operating activities and borrowings under our revolving credit facility. On March 31, 2019 , our cash and cash equivalents balance was $120.5 million . There were outstanding borrowings of $96.0 million under our revolving credit facility at March 31, 2019 . The maximum available borrowings under our revolving credit facility at March 31, 2019 were $396.3 million . As of March 31, 2019 , we were contingently liable under letters of credit totaling $7.7 million , which reduces our availability to borrow under our revolving credit facility.

Cash Flows From (Used In) Operating Activities

Our operating cash flow is primarily affected by our ability to invoice and collect from our customers in a timely manner, our management of 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 were 70 and 69 for the three months ended March 31, 2019 and 2018 , respectively. For the three months ended March 31, 2019 and 2018 , our net cash from (used in) operating activities was $47.3 million and $(18.0) million , respectively. The increase in net cash flows from operating activities during the three months ended March 31, 2019 when compared to the same period in 2018 was primarily due to the timing of receivables collection.

Cash Flows From (Used In) Investing Activities

For the three months ended March 31, 2019 our net cash used in investing activities was $10.2 million , which was primarily due to the purchase of equipment to support a managed IT service contract, infrastructure investments and capitalized software for internal use. For the three months ended March 31, 2018 our net cash used in investing activities was $9.0 million , which was primarily due to the purchase of equipment to support a managed IT service contract, infrastructure investments and capitalized software for internal use.

Cash Flows From (Used in) Financing Activities

For the three months ended March 31, 2019 , our net cash flow from financing activities was $78.1 million , which was primarily due to net borrowings under revolving credit facility and dividend payments. The net increase in borrowings for the three months ended March 31, 2019 is due to funding requirements to acquire Kforce Government Solutions on April 1, 2019. For the three months ended March 31, 2018 , our net cash flow from financing activities were $27.9 million , which were primarily due to net borrowings under our revolving credit facility and exercise of stock options partially offset by dividend payments.

Revolving Credit Facility

We maintain a credit agreement 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 $75 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments. The maturity date is August 17, 2022 . Borrowings under our credit agreement are collateralized by substantially all the assets of us and our Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: a London Interbank Offer Rate based rate plus market spreads ( 1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads ( 0.25% to 1.25% based on our consolidated total leverage ratio). There were outstanding borrowings of $96.0 million on our revolving credit facility at March 31, 2019 . As of and during the three months ended March 31, 2019 , we were in compliance with the financial covenants under the credit agreement.

Capital Resources

We believe the capital resources available to us from cash on hand, our remaining capacity under our revolving credit facility, and cash from our operations are adequate to fund our anticipated cash requirements for at least the next year. We anticipate financing our internal and external growth through cash from operating activities, borrowings under our revolving credit facility or other debt and issuance of equity.

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 the three months ended March 31, 2019 and 2018 , we declared and paid quarterly dividends in the amount of $0.27 per share and $0.25 per share, respectively, on both classes of our common stock. While we expect to continue the cash dividend program, any future dividends declared will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash requirements, as well as such other factors that our Board of Directors deems relevant.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use letters of credit issued to satisfy certain contractual terms with our customers. As of March 31, 2019 , $7.7 million in letters of credit were issued but undrawn. We have an outstanding performance bond in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company to fulfill technical support requirements for the Royal Saudi Air Force. This performance bond is guaranteed by a letter of credit in the amount of $14 thousand .

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 condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. Actual results may differ from these estimates under different assumptions or conditions. Our significant accounting policies for 2018 are described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 , previously filed with the SEC. There have been no material changes to our critical accounting estimates and policies from those discussed in our 2018 Annual Report on Form 10-K, other than lease accounting associated with the implementation of ASC 842, which is described below.

Lease Accounting

Our ROU asset is recognized as the lease liability, any initial indirect costs and any prepaid lease payments, less any lease incentives. Our lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Our lease payments consist of amounts relating to the use of the underlying asset during the lease term, specifically fixed payments, payment to be made in optional periods when we are reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease and the amounts probable of being owned by us under residual guarantees. Our variable lease payments are excluded in measuring ROU asset and lease liability because they do not depend on an index or a rate or are not in substance fixed payments. We exclude lease incentives and initial direct cost incurred from our lease payments. Our leases typically do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments.

Recently Adopted Accounting Standards Updates

ASU 2016-02, Leases (Topic 842) supersedes the leases requirements in Topic 840, Leases . The objective of Topic 842 is to establish the principles that lessees and lessors should apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. We elected to adopt using the modified retrospective method at the beginning of the period of adoption, January 1, 2019, through the recognition of a lease liability and corresponding right of use asset. We elected the following transition related practical expedients; not to reassess whether any expired or existing contracts are or contain leases, not to reassess lease classification as determined under ASC 840 and, not to reassess initial direct costs for any existing lease. We have also elected not to apply the recognition and measurement requirements to short-term leases (less than 1 year). Additional details are included in Note 4 in our condensed consolidated financial statements in Item 1.

ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , which helps organizations reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 (TCJA), enacted on December 22, 2017. We elected to adopt this ASU at the beginning of the period of adoption, January 1, 2019. We recorded an adjustment to the 2019 opening retained earnings in the amount of $24 thousand related to the change in the U.S. federal corporate tax rate.

Recently Issued But Not Yet Adopted ASUs

The FASB has issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 , which resolves the diversity in practice concerning the manner in which entities account for transactions on the basis of their view of the economics of the collaborative arrangement. A collaborative arrangement, as defined by the guidance in Topic 808, is a contractual arrangement under which two or more parties actively participate in a joint operating activity and are exposed to significant risks and rewards that depend on the activity’s commercial success. In particular, the amendments in ASU 2018-18 (1) clarify that certain transactions between collaborative participants should be accounted for as revenue under Topic 606 when the collaborative participant is a customer in the context of the unit of account, and that, in those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation and disclosure requirements; (2) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (i.e., a distinct good or service), limited to when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606; and (3) clarify that in a transaction that is not directly related to sales to third parties, presenting the transaction as revenue would be precluded if the collaborative participant counterparty was not a customer. The amendments are effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Note that early adoption is permitted, including adoption in any interim period for public business entities for periods for which financial statements have not yet been issued. We are currently evaluating the effect on our condensed consolidated financial statements.

The FASB has issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which focuses on improving the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s financial statements. The amendments in ASU 2018-13 modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement . Specifically, the amendments in this ASU remove disclosure requirements in Topic 820 related to (1) the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; (3) the valuation processes for Level 3 fair value measurements; and (4) for non-public entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The ASU also modifies disclosure requirements such that (1) in place of a rollforward for Level 3 fair value measurements, a non-public entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy

and purchases and issues of Level 3 assets and liabilities; (2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date that restrictions from redemption might lapse, only if the investee has communicated the timing to the entity or announced the timing publicly; and (3) it is clear that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Additionally, the ASU adds disclosure requirements for public entities about (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period, and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Note that early application is permitted for all entities; moreover, an entity is allowed to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We are currently evaluating when we will adopt this standard as well as its effect on our condensed consolidated financial statements.

As part of its disclosure framework project, the FASB has issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans , which modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Specifically, certain disclosure requirements are removed from Subtopic 715-20, Compensation—Retirement Benefits—Defined Benefit Plans—General , including, among others, (1) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year; (2) the disclosures related to the June 2001 amendments to the Japanese Welfare Pension Insurance Law; and (3) related party disclosures concerning the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan. Certain other disclosure requirements are added to Subtopic 715-20, including (1) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates; and (2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Finally, the amendments in this ASU clarify disclosure requirements in Paragraph 715-20-50-3. The amendments are effective for fiscal years ending after December 15, 2020. We are currently evaluating the effect on our condensed consolidated financial statements.

The FASB has issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) , which aims to reduce complexity in the accounting for costs of implementing a cloud computing service arrangement. In fact, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this ASU require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40, Intangibles—Goodwill and Other—Internal-Use Software, in order to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs to develop or obtain internal-use software that cannot be capitalized under Subtopic 350-40 (e.g., training costs and certain data conversion costs) also cannot be capitalized for a hosting arrangement that is a service contract. Additionally, the amendments in this ASU require the entity (customer) to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement (i.e., the noncancellable period of the arrangement plus periods covered by (1) an option to extend the arrangement if the customer is reasonably certain to exercise that option, (2) an option to terminate the arrangement if the customer is reasonably certain not to exercise the termination option and (3) an option to extend (or not to terminate) the arrangement in which exercise of the option is in the control of the vendor. The amendments in this ASU also require the entity to present the expense related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement, and to classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. Note that the accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this ASU. The amendments are effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We are currently evaluating methods of adoption as well as the effect on our condensed consolidated financial statements.

The FASB has issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities , which reduces the cost and complexity of financial reporting associated with consolidation of variable interest entities (VIEs). Specially, the indirect interests held through related parties in common control arrangements should be considered on a proportional basis (as opposed to a direct interest in its entirety) for determining whether fees paid to decision makers and service providers are variable interests. This is consistent with how indirect interests held through related parties under common control are considered for determining whether a reporting entity must consolidate a VIE. The amendments are effective

for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We do not expect the adoption of this ASU to have a material effect on our condensed consolidated financial statements.

The FASB has issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting which supersedes the guidance in Subtopic 505-50, Equity—Equity-Based Payments to Non- Employees . In particular, ASU 2018-07 expands the scope of Topic 718, Compensation—Stock Compensation (which previously only included payments to employees), to include share-based payment transactions for acquiring goods and services from nonemployees. In fact, an entity should now apply the requirements of Topic 718 to non-employee awards, except for specific guidance on inputs to an option pricing model and the attribution of cost (i.e., the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). Additionally, the amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in the grantor’s own operations by issuing share-based payment awards, and clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers . The amendments are effective for fiscal years beginning after December 15, 2019, and for interim periods with fiscal years beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. We do not expect the adoption of this ASU to have a material effect on our condensed consolidated financial statements.

The FASB has issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which simplifies the manner in which an entity determines the amount of a goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. In computing the implied fair value of goodwill under Step 2, an entity, prior to the amendments in ASU 2017-04, had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities, including unrecognized assets and liabilities, in accordance with the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the amendments in this ASU, an entity should (1) perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and (2) recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, with the understanding that the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Public entities should adopt the amendments in this ASU prospectively for their annual, or any interim periods, in fiscal years beginning after December 15, 2019. Early adoption is permitted for all entities for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We will evaluate adopting when we perform our goodwill impairment test in 2019. We do not expect the adoption of this ASU to have a material effect on our condensed consolidated financial statements.

Other ASUs effective after March 31, 2019 are not expected to have a material effect on our condensed consolidated financial statements.


Item 3.	Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risk relates to changes in interest rates for borrowing under our revolving credit facility. At March 31, 2019 , we had an outstanding balance of $96.0 million on our revolving credit facility. Borrowings under our revolving credit facility bear interest at variable rates. A hypothetical 10% increase in interest rates would have a $0.1 million effect on our interest expense for the three months ended March 31, 2019 .

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 and internal control over financial reporting. 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 March 31, 2019 , under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), management evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level described above.

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

PART II – OTHER INFORMATION


Item 1.	Legal Proceedings

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

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


Item 1A.	Risk Factors

There have been no material changes from the risk factors described in the “Risk Factors” section of our Annual Report on the Form 10-K for the year ended December 31, 2018 .
