NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable, and collectability is reasonably assured. The Company enters into three types of contracts: time-and-materials, cost-based, and fixed-price.

•

Time-and-Materials Contracts.

Revenue for time-and-materials contracts is recorded on the basis of allowable labor hours worked multiplied by the contract-defined billing rates, plus the costs of other items used in the performance of the contract. Profits and losses on time-and-materials contracts result from the difference between the cost of services performed and the contract-defined billing rates for these services.

•

Cost-Based Contracts

Revenue under cost-based contracts is recognized as costs are incurred. Applicable estimated profit, if any, is included in earnings in the proportion that incurred costs bear to total estimated costs. Incentives, award fees, or penalties related to performance are also considered in estimating revenue and profit rates based on actual and anticipated awards, taking into consideration factors such as the Company’s prior award experience and communications with the customer regarding performance.

•

Fixed-Price Contracts

Revenue for fixed-price contracts is recognized when earned, generally as work is performed. Services performed vary from contract to contract and are not always uniformly performed over the term of the arrangement. Fixed-price contracts may contain multiple elements that must be evaluated to determine if they represent separate units of accounting that have stand-alone value. If the assessment is made that there is more than one unit of accounting, the contract value is then allocated to each unit based upon management’s best estimate of selling price and the appropriate revenue recognition method is applied to each unit. The Company recognizes revenue in a number of different ways on fixed-price contracts based upon the nature of the services to be provided and an assessment of what best mirrors the pattern of performance for the deliverable/contract, including:

•

Proportional Performance:

Revenue on certain fixed-price contracts is recognized based on proportional performance when the provision of services extends beyond an accounting period with more than one discrete performance act, and

progress towards completion can be measured based on a reliable output or input. Under this method, revenue is recorded each period based upon certain contract performance input measures incurred (labor hours, labor costs, or total costs) or output measures completed, expressed as a proportion of a total project estimate. Progress on a contract is monitored regularly to ensure that revenue recognized reflects project status. When hours or costs incurred are used as the basis for revenue recognition, the hours or costs incurred represent a reasonable surrogate for output measures of contract performance, including the presentation of deliverables to the client. Clients are obligated to pay as services are performed, and in the event that a client cancels the contract, payment for services performed through the date of cancellation is typically negotiated with the client.

•

Specific Performance

hen the services to be performed consist of a single act, revenue is recognized at the time the act is performed or at the completion of the single service.

•

Straight-Line

: When services are performed or are expected to be performed consistently throughout an arrangement, or when the Company is compensated on a retainer or fixed-fee basis, revenue is recognized ratably over the period benefited.

•

Completed Contract

: Revenue and costs on certain fixed-price contracts are recognized at completion if the final act is so significant to the arrangement that value is deemed to be transferred only at completion.

Revenue recognition requires the Company to use judgment relative to assessing risks, estimating contract revenue and costs or other variables, and making assumptions for scheduling and technical issues. Due to the size and nature of many of the Company’s contracts, the estimation of revenue and estimates at completion can be complicated and are subject to many variables. Contract costs include labor, subcontractor costs, and other direct costs, as well as an allocation of indirect costs. At times, the Company must also make assumptions regarding the length of time to complete the contract because costs include expected increases in wages, prices for subcontractors, and other direct costs. From time to time, facts develop that require the Company to revise its estimated total costs or hours and thus the associated revenue on a contract. To the extent that a revised estimate affects contract profit or revenue previously recognized, the Company records the cumulative effect of the revision in the period in which the facts requiring the revision become known. A provision for the full amount of an anticipated loss on any type of contract is recognized in the period in which it becomes probable and can be reasonably estimated. As a result, operating results could be affected by revisions to prior accounting estimates.

Contractual arrangements are evaluated to assess whether revenue should be recognized on a gross versus net basis. Management’s assessment when determining gross versus net revenue recognition is based on several factors, such as whether the Company serves as the primary service provider, has autonomy in selecting subcontractors, or has credit risk, all of which are primary indicators that the Company serves as the principal to the transaction. In such cases, revenue is recognized on a gross basis. When such indicators are not present and the Company is primarily functioning as an agent under an arrangement, revenue is recognized on a net basis.

The approximate percentage of revenue by contract type was as follows:

	Year ended December 31,
	2015			2014			2013
Time-and-materials		43	%		47	%		52	%
Fixed-price		38	%		34	%		29	%
Cost-based		19	%		19	%		19	%
Total		100	%		100	%		100	%

Payments to the Company on cost-based contracts with the federal government are provisional payments subject to adjustment upon audit by the government. Such audits have been finalized through December 31, 2006, and any adjustments have been immaterial. Contract revenue for subsequent periods has been recorded in amounts that are expected to be realized upon final audit and settlement of costs in those years.

The Company generates invoices to clients in accordance with the terms of the applicable contract, which may not be directly related to the performance of services. Unbilled receivables are invoiced based upon the achievement of specific events as defined by each contract, including deliverables, timetables, and incurrence of certain costs. Unbilled receivables are classified as a current asset. Advanced billings to clients in excess of revenue earned are recorded as deferred revenue until the revenue recognition criteria are met. Reimbursements of out-of-pocket expenses are included in revenue with corresponding costs incurred by the Company included in the cost of revenue. The Company records revenue net of taxes collected from customers to be remitted to governmental authorities.

The Company may proceed with work based upon client direction prior to the completion and signing of formal contract documents. It has a review process for approving any such work. Revenue associated with such work is recognized only when it can be reliably estimated and realization is probable. The Company bases its estimates on a variety of factors, including previous experiences with the client, communications with the client regarding funding status, and its knowledge of available funding for the contract.

Cash and Cash Equivalents

The Company considers cash on deposit and all highly liquid investments with original maturities of three months or less when purchased to be cash and cash equivalents.

Restricted Cash

The Company has restricted cash representing amounts held in escrow accounts and/or not readily available due to contractual restrictions.

Allowance for Doubtful Accounts

The Company considers a number of factors in its estimate of allowance for doubtful accounts, including the customer’s financial condition, historical collection experience, and other factors that may bear on collectability of the receivables. The Company writes off contract receivables when such amounts are determined to be uncollectible. Losses have historically been within management’s expectations.

Property and Equipment

Property and equipment are carried at cost and are depreciated using the straight-line method over their estimated useful lives, which range from two to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of the economic life of the improvement or the related lease term. Assets acquired in acquisitions are recorded at fair value.

The Company is required to review long-lived assets and identifiable intangibles subject to amortization for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less cost to sell.

Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired, less liabilities assumed, based upon their respective fair values, with the excess recorded as goodwill. Goodwill represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead are reviewed for impairment annually, or more frequently if impairment indicators arise. Intangible assets with estimable useful lives are amortized over such lives and reviewed for impairment if impairment indicators arise.

The Company performs its annual goodwill impairment review as of September 30 of each year. For the purposes of performing this review, the Company has concluded that it is one reporting unit. For the annual impairment review as of September 30, 2015, the Company opted to perform a qualitative assessment of whether it is more likely than not that its reporting unit's fair value is less than its carrying amount. If, after completing its qualitative assessment, the Company determines that it is more likely than not that the estimated fair value of the reporting unit exceeded its carrying amount, it may conclude that no impairment exists. If the Company concludes otherwise, a two-step goodwill impairment test must be performed, which includes a comparison of the fair value of the reporting unit to the carrying value.

The Company’s qualitative analysis as of September 30, 2015 included macroeconomic and industry and market specific considerations, financial performance indicators and measurements, and other factors. Based on the Company’s qualitative assessment, it determined that it is more likely than not that the fair value of its one reporting unit exceeded its carrying amount, and thus the two-step impairment test was not required to be performed for 2015. Therefore, based upon management’s review, no goodwill impairment charge was required as of September 30, 2015. Historically, the Company has recorded no goodwill impairment charges.

The Company is required to review long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less cost to sell.

Capitalized Software

The Company capitalizes eligible costs to develop enhancements and upgrades to internal-use software that are incurred subsequent to the preliminary project stage. Amortization expense is recorded on a straight-line basis over the expected economic life, typically three to five years. During the years ended December 31, 2015, 2014 and 2013, the costs capitalized for the development of internal- use software were not material to the Company’s consolidated financial statements.

Deferred Rent

The Company recognizes rent expense on a straight-line basis over the non-cancellable term of each lease, including renewal option periods when renewal is reasonably assured or executed. Lease incentives or abatements received at or near the inception of leases are accrued and amortized ratably over the life of the lease.

Stock-based

Compensation

The Company recognizes stock-based compensation expense related to share-based payments to employees, including grants of employee stock options, restricted stock awards, restricted stock units (“RSUs”), and cash-settled restricted stock units (“CSRSUs”) on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes expense for performance-based share awards (“PSAs”), which have a performance condition and a market condition, on a straight-line basis over the performance period. Non-employee director awards do not include vesting conditions and therefore are expensed when issued.

Compensation expense is based on the estimated fair value of these instruments and the estimated number of shares the Company ultimately expects will vest. The Company estimates the rate of future forfeitures based on factors such as historical experience and employee class. In addition, the estimation of PSAs that will ultimately vest requires judgment based on performance conditions. Changes to these estimates are recorded as a cumulative adjustment in the period estimates are revised.

The fair value of stock options, restricted stock awards, RSUs, PSAs and non-employee director awards is estimated based on the fair value of a share of common stock at the grant date. The Company has elected to use the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The fair value of PSAs is estimated using a Monte Carlo simulation model.

CSRSUs are settled only in cash payments. The cash payment is based on the fair value of the Company’s stock price at the vesting date, calculated by multiplying the number of CSRSUs vested by the Company’s closing stock price on the vesting date, subject to a maximum payment cap and a minimum payment floor. The Company treats these awards as liability-classified awards, and therefore accounts for them at fair value estimated based on the closing price of the Company’s stock at the reporting date.

Other Comprehensive Income

Other comprehensive income represents foreign currency translation adjustments arising from the use of differing exchange rates from period to period. The financial positions and results of operations of the Company’s foreign subsidiaries are based on the local currency as the functional currency and are translated to U.S. dollars for financial reporting purposes. Assets and liabilities of the subsidiaries are translated at the exchange rate in effect at each period-end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Translation adjustments are included in accumulated other comprehensive income (loss) in stockholders’ equity in the Company’s consolidated balance sheets. The activity included in other comprehensive income (loss) in the Company’s consolidated statements of comprehensive income related to foreign currency translation adjustments for each period reported is summarized below.

	Year ended December 31,
	2015			2014			2013
Foreign currency translation adjustments (1)	$	(5,676	)	$	(2,017	)	$	251
Realized losses reclassified into earnings ( 2 )		666			526			—
Other comprehensive (loss) income, net of tax (3)	$	(5,010	)	$	(1,491	)	$	251

(1) In the third quarter of 2015, the Company recorded an adjustment to its foreign currency translation totaling approximately $4 million, primarily related to goodwill, intangible assets and fixed assets for certain acquired international subsidiaries.

(2) Represents the reclassification of foreign currency translation adjustments from accumulated other comprehensive loss into earnings as a result of closing international offices. Amounts are included in the other expense line item in the consolidated statements of comprehensive income.

(3) Net of tax of $1.0 million, $0.4 million and $0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Fair Value of Financial Instruments

The Company's financial instruments, including cash and cash equivalents, contract receivables, accounts payable, accrued expenses, and other current liabilities, are carried at cost, which the Company believes approximates their fair values at December 31, 2015 and December 31, 2014, due to their short maturities. The Company believes the carrying value of other long-term liabilities related to capital expenditure obligations approximates their fair value at December 31, 2015 based on the current rates offered to us for similar instruments with comparable maturities. The Company believes the carrying value of its lines of credit payable at December 31, 2015 and 2014 approximate the estimated fair value for debt with similar terms, interest rates, and remaining maturities currently available to companies with similar credit ratings.

The Company applies the provisions of ASC 820,

Fair Value Measurements and Disclosures

(“ASC 820”), to its assets and liabilities that are required to be measured at fair value pursuant to other accounting standards including assets and liabilities resulting from the Company’s nonqualified deferred compensation plan and foreign currency forward contract agreements not eligible for hedge accounting. The fair value of assets and liabilities resulting from the Company’s nonqualified deferred compensation plan and foreign currency forward contract agreements at December 31, 2015 and 2014 and the changes in fair value for the years ended December 31, 2015, 2014, and 2013 were immaterial.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The Company evaluates its ability to benefit from all deferred tax assets and establishes valuation allowances for amounts it believes are not more likely than not to be realizable. For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements.

Penalties, if probable and reasonably estimable, and interest expense related to uncertain tax positions are not recognized as a component of income tax expense but recorded separately in indirect expenses.

Treasury Shares

Treasury shares are accounted for under the cost method.

Segment

, Customer and Geographic Information

The Company has concluded that it operates in one segment based upon the consolidated information used by its chief operating decision maker in evaluating the financial performance of its business and allocating resources. This single segment represents the Company’s core business, professional services for government and commercial clients. Although the Company describes its multiple service offerings in four markets to provide a better understanding of the Company’s business operations, the Company does not manage its business or allocate resources based upon those service offerings or markets.

Approximately $540 million, $532 million, and $550 million of the Company’s revenue for the years 2015, 2014, and 2013, respectively, was derived under prime contracts and subcontracts with agencies and departments of the federal government representing 48%, 51%, and 58% of total revenue. No other customer accounted for 10% or more of the Company’s revenue during the years 2015, 2014, and 2013.

The Company’s international operations offer services to both commercial and non-U.S. government customers. Revenue is attributed to location based on the geographic areas to which a contract is awarded. The Company’s revenue generated from international clients as a percentage of total revenue was approximately 11%, 12%, and 9% for the years 2015, 2014, and 2013.

Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and contract receivables. The majority of the Company’s cash transactions are processed through one U.S. commercial bank. Cash held domestically in excess of daily requirements is used to reduce any amounts outstanding under the Company’s Credit Facility. As of December 31, 2015 and 2014, the Company held approximately $6.5 million and $10.1 million, respectively, of cash in foreign bank accounts. To date, the Company has not incurred losses related to cash and cash equivalents.

The Company’s contract receivables consist principally of contract receivables from agencies and departments of, as well as from prime contractors to, the federal government, other governments, and commercial organizations. The Company believes that

this

credit risk with

respect to

contract receivables, is limited due to the credit worthiness of the U.S. government. Contract receivable credit risk is also limited due to a large number of customers in differing agencies of the U.S. government. The Company extends credit in the normal course of operations and does not require collateral from its clients.

The Company has historically been, and continues to be, heavily dependent upon contracts with the federal government and is subject to audit by agencies of the federal government. Such audits determine, among other things, whether an adjustment of invoices rendered to the government is appropriate under the underlying terms of the contracts. Management does not expect any significant adjustments as a result of government audits that will adversely affect the Company’s financial position.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Recent Accounting Pronouncements not yet Adopted

In May 2014, the FASB issued ASU 2014-09,

Revenue from Contracts with Customers

(

Topic 606)

. ASU 2014-09 provides a single comprehensive revenue recognition framework and supersedes almost all existing revenue recognition guidance. Included in the new principles-based revenue recognition model are changes to the basis for deciding on the timing for revenue recognition. In addition, the standard expands and improves revenue disclosures. In August 2015, the FASB issued ASU 2015-14,

Revenue from Contracts with Customers

(

Topic 606)

: Deferral of Effective Date

, to amend ASU 2014-09 to defer the effective date of the new revenue recognition standard. As a result, ASU 2014-09 is effective for the Company for its fiscal year 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The Company is currently evaluating the impact of adopting ASU 2014-09.

In April 2015, the FASB issued ASU 2015-05,

Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement

(Subtopic 350-40).

ASU 2015-05 provides guidance to help entities evaluate whether a cloud computing arrangement contains a software license that should be accounted for as internal-use software or as a service contract. The update is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. Upon adoption, an entity has the option to apply the provisions of ASU 2015-05 either prospectively to all arrangements entered into or materially modified, or retrospectively.

The adoption of ASU 2015-05 is not expected to have a material impact on the Company’s consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16,

Simplifying the Accounting for Measurement-Period Adjustments (Topic 805).

ASU 2015-16 eliminates the requirement for an acquirer to retrospectively account for adjustments made to provisional amounts recognized in a business combination to reflect new information that existed as of the acquisition date. Instead, an acquirer will recognize these measurement-period adjustments during the period in which it determines the amount of the adjustment.

ASU 2015-16 is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. The adoption of ASU 2015-16 is not expected to have a material impact on the Company’s consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17,

Balance Sheet Classification of Deferred Taxes

(Topic 740). This update requires an entity to classify deferred tax liabilities and assets as noncurrent within a classified statement of financial position. ASU 2015-17 is effective for annual and interim reporting periods beginning after December 15, 2016. This update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early application is permitted as of the beginning of the interim or annual reporting period. The adoption of ASU 2015-17 is not expected to have a material impact on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02,

Leases

(Topic 842). This update revises an entity’s accounting for operating leases and requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. This update also requires certain qualitative and specific quantitative disclosures. ASU 2016-02 does not significantly change the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee. This update is effective for the first interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2016-02.

These goodwill adjustments were not significant to our previously reported operating results or financial position. See further discussion of the Company’s business combinations in “Note F—Business Combinations.”

Other Intangible Assets

Intangible assets are primarily amortized over periods ranging from approximately 1 to 10 years. The weighted-average period of amortization for all intangible assets as of December 31, 2015, is 8.7 years. The customer-related intangible assets related to the business combinations, which consist of customer contracts, backlog, and non-contractual customer relationships, are being amortized based on estimated cash flows and respective estimated economic benefit of the assets. The weighted-average period of amortization of the customer-related intangibles is 8.7 years. Intangible assets related to acquired developed technology are being amortized on an accelerated basis over a weighted-average period of 5.5 years.

Other intangibles consisted of the following at December 31:

NOTE F—BUSINESS COMBINATIONS

Olson

On November 5, 2014, the Company completed the acquisition of OCO Holdings, Inc. and its various subsidiaries, including Olson + Co., Inc. (collectively, “Olson”), a leading provider of marketing technology and digital services based in Minneapolis, Minnesota. As a result of the acquisition, Olson became a wholly owned subsidiary of the Company. The aggregate purchase price of approximately $298.2 million in cash was funded by the Company’s Credit Facility (as defined in “Note I – Long-Term Debt” below). The acquisition expanded the Company’s existing digital technology and strategic communications work and strengthened its ability to bring more integrated solutions to an expanded client base, including multi-channel marketing initiatives across web, mobile, email, social, print, broadcast and off-premise platforms.

The acquisition

was accounted for under the acquisition method. The allocation of the total purchase price to the tangible and intangible assets and liabilities of Olson is based on management’s estimate of fair value as of the acquisition date and was completed in the fourth quarter of 2015. The Company engaged an independent valuation firm to assist management in the allocation of the purchase price to goodwill and to other acquired intangible assets. The excess of the purchase price over the estimated fair value of the net tangible assets acquired was approximately $293.4 million. The Company has allocated approximately $228.5 million to goodwill and $64.9 million to other intangible assets. The goodwill recorded as part of the acquisition primarily reflects the value of providing an established platform to leverage the Company’s existing digital interactive technologies and domain expertise, synergies expected to arise from providing end-to-end customer solutions to a combined client-base across all channels, as well as any intangible assets that do not qualify for separate recognition. The weighted average amortization period for the amount allocated to other intangible assets in total is 9.6 years from the acquisition date. The intangible assets consist of approximately $60.3 million of customer-related intangibles that are being amortized over 10.2 years from the acquisition date, $4.0 million of marketing-related intangibles that were amortized over 1.2 years from the acquisition date, and $0.6 million of developed technology intangibles that are being amortized over 6.2 years from the acquisition date. Olson was a stock purchase for tax purposes; therefore, goodwill and amortization of other intangibles created via this acquisition are not deductible for income tax purposes.

During the year ended December 31, 2015, the Company recorded an increase to goodwill of $3.4 million related to measurement-period adjustments to the preliminary purchase price allocation. The measurement-period adjustments were primarily related to reductions of $7.3 million and $5.9 million to the valuation of fixed assets and accrued expenses and other liabilities, as well as a $1.8 million holdback adjustment that increased the purchase price to $298.2 million. Goodwill adjustments were not significant to our previously reported operating results or financial position.

The purchase price allocation is summarized as follows:

Cash	$	8,816
Contract receivables		36,879
Other current and non-current assets		1,512
Property and equipment		8,571
Customer-related intangibles		60,338
Marketing-related intangibles		3,947
Developed technology intangibles		578
Goodwill		228,527
Total Assets		349,168

Accounts payable		9,792
Accrued expenses and other liabilities		7,126
Accrued salaries and benefits		5,378
Deferred revenue		9,742
Deferred taxes and income tax payable		18,922
Total Liabilities		50,960
Net Assets	$	298,208

The results of operations of the Olson acquisition are included in the Company’s consolidated statements of comprehensive income for the year ended December 31, 2015. For the year ended December 31, 2014, Olson contributed net revenues of $23.0 million and net earnings of $2.2 million since the acquisition date of November 5, 2014

, excluding transaction-related acquisition costs of $1.6 million, as well as interest expense, amortization of intangible assets resulting from the acquisition, stock-based compensation expense, corporate allocations and integration costs.

The following unaudited condensed pro forma information presents combined financial information as if the acquisition of Olson had been effective at the beginning of fiscal year 2013. As a result, fiscal year 2014 represents the pro forma results for year two of the acquisition. The pro forma information includes adjustments reflecting changes in the amortization of intangibles, acquisition-related expense, stock-based compensation expense,

and interest expense, and records income tax effects as if Olson had been included in the Company’s results of operations. The pro forma information for fiscal year 2014 also includes an adjustment to eliminate $2.6 million of operating income related to the reduction of an Olson contingent liability that was settled as a result of the acquisition.

CityTech

March 2014, the Company acquired CityTech, Inc. (“CityTech”), a Chicago-based digital interactive consultancy specializing in enterprise applications development, web experience management, mobile application development, cloud enablement, managed services, and customer experience management solutions. The acquisition added expertise to the Company’s content management capabilities and complemented its digital and interactive business. During the first quarter of 2015, the Company finalized its valuation of the assets acquired and liabilities assumed as a result of the acquisition. The purchase was immaterial to the Company’s financial statements taken as a whole.

Mostra

In February 2014, the Company completed its acquisition of Mostra SA (“Mostra”), a strategic communications consulting company based in Brussels, Belgium. Mostra offers end-to-end, multichannel communications solutions to assist government and commercial clients, in particular the European Commission. The acquisition extended the Company’s strategic communications capabilities globally to complement its policy work and enhance its strategy of providing a full suite of services that leverages its research and advisory services. During the first quarter of 2015, the Company finalized its valuation of the assets acquired and liabilities assumed as a result of the acquisition. The purchase was immaterial to the Company’s financial statements taken as a whole.

ECA

In July 2013, the Company hired the staff of, and purchased certain assets and liabilities from, Ecommerce Accelerator LLC (“ECA”), an e-commerce technology-based services firm based in New York, New York. The addition of ECA enhanced ICF’s multi-channel, end-to-end e-commerce solutions. In connection with the acquisition, the Company recorded a contingent consideration payable reflected in other long-term liabilities at the estimated fair value of $2.8 million at December 31, 2013. The fair value of the contingent liability was reduced to zero in the first quarter of 2014 and the change in the fair value measurement of $2.8 million was recorded as a reduction to indirect and selling expenses. The Company is no longer required to pay contingent consideration to ECA, as the parties mutually agreed to the release of this potential obligation in the third quarter of 2014. The purchase was immaterial to the Company’s financial statements taken as a whole.

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

Long-term Debt [Text Block]

NOTE I—LONG-TERM DEBT

The Company entered into a Fourth Amended and Restated Business Loan and Security Agreement with a syndication of 11 commercial banks on May 16, 2014, which was further modified on November 5, 2014 (the “Credit Facility”). The Credit Facility matures on May 16, 2019 and allows for borrowings of up to $500.0 million without a borrowing base requirement, taking into account financial, performance-based limitations and provides for an “accordion,” which permits additional revolving credit commitments of up to $100.0 million, subject to lenders’ approval. The Credit Facility provides for stand-by letters of credit aggregating up to $30.0 million that reduce the funds available under the Credit Facility when issued. The Credit Facility is collateralized by substantially all of the assets of the Company and requires that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants, as defined in the Credit Facility, require, among other things, that the Company maintain, on a consolidated basis for each quarter, a fixed charge coverage ratio of not less than 1.25 to 1.00 and a leverage ratio of not more than 3.75 to 1.00. As of December 31, 2015, the Company was in compliance with its covenants under the Credit Facility.

As of December 31, 2015, the Company had $311.5 million in long-term debt outstanding, $3.7 million in outstanding letters of credit, and available borrowing capacity of $184.8 million under the Credit Facility (excluding the accordion). Taking into account the financial, performance-based limitations, available borrowing capacity (excluding the accordion) was $131.9 million as of December 31, 2015.

The Company’s debt issuance costs, which are included within other assets, are amortized over the term of indebtedness. Amortizable debt issuance costs were $5.8 million as of both December 31, 2015 and December 31, 2014. Accumulated amortization related to debt issuance costs was $4.0 million and $3.5 million, as of December 31, 2015 and 2014, respectively. Amortization expense of $0.5 million was recorded for each of the years ended December 31, 2015, 2014, and 2013, respectively.

The Company has the ability to borrow funds under its Credit Facility at interest rates based on both LIBOR (1, 3, or 6 month rates) and prime rates, at its discretion, plus their applicable margins and payable monthly. At December 31, 2015 and 2014, the Credit Facility was subject to a commitment fee on the unused portion of the Credit Facility of 0.25% and 0.30% per annum, respectively.

Long-term debt outstanding and the weighted average interest rate at December 31 is summarized as follows:

	2015					2014
	Debt Outstanding		Weighted Average Interest Rate			Debt Outstanding		Weighted Average Interest Rate
Revolving Line of Credit/Swing Line	$	311,532		2.23	%	$	350,052		2.41	%

Letters of Credit

At December 31, 2015 and 2014, the Company had outstanding letters of credit totaling approximately $3.7 million and $4.4 million, respectively. These letters of credit are renewed annually.

At December

31, 2015 and 2014, the Company had net operating loss (“NOL”) carry-forwards for foreign income taxes of approximately $6.9

million and $1.9 million, respectively, all of which may be carried forward indefinitely.

At December

31, 2015, the Company had NOL carry-forwards for federal and state income tax purposes of approximately $15.2 million, which expire in 2034. The Company also had federal tax credits totaling $0.2 million, all of which may be carried forward indefinitely. The Company acquired these NOLs and credits as a result of its purchase of Olson in November 2014. Internal Revenue Code Section 382 imposes an annual limitation on the use of a corporation’s NOLs, tax credits and other carryovers after an “ownership change” occurs.

Section

382 imposes an annual limitation on the amount of post-ownership change taxable income a corporation may offset with pre-ownership change NOLs and credits. In general, the annual limitation is determined by multiplying the value of the corporation’s stock immediately before the ownership change (subject to certain adjustments) by the applicable long-term tax-exempt rate. Any unused portion of the annual limitation is available for use in future years until such NOLs are scheduled to expire (in general, NOLs may be carried forward 20 years). The Company presently estimates that it will be able to fully utilize the acquired NOLs and credits prior to their expiration.

At December 31, 2015, the Company had gross state income tax credit carry-forwards of approximately $2.0 million, which expire between 2017 and 2025. A deferred tax asset of approximately $1.3 million (net of federal benefit) has been established related to these state income tax credit carry-forwards as of December 31, 2015.

The need to establish valuation allowances for deferred assets is based on a more-likely-than-not threshold that the benefit of such assets will be realized in future periods. Appropriate consideration has been given to all available evidence, including historical operating results, projections of taxable income, and tax planning alternatives. The Company concluded that a valuation allowance of approximately $0.9 million and $0.5 million was required for tax attributes related to specified foreign jurisdictions as of December 31, 2015 and 2014, respectively.

Effective January 1, 2009, the Company made no provisions for deferred U.S. income taxes or additional foreign taxes on any unremitted earnings of its controlled foreign subsidiaries because the Company considers these earnings to be permanently invested. If these earnings were repatriated, in the form of dividends or otherwise, the Company would be subject to U.S. income tax on these earnings. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with this hypothetical calculation; however, unrecognized foreign tax credit carry forwards would be available to reduce some portion of the U.S. tax liability. The Company has $1.9 million of foreign tax credits available for carry forward related to its foreign branch operations as of December 31, 2015.

On September 13, 2013, the Treasury Department and the Internal Revenue Service issued final regulations regarding the deduction and capitalization of amounts paid to acquire, produce, improve or dispose of tangible personal property. These regulations are generally effective for tax years beginning on or after January 1, 2014. The application of these regulations did not have a material impact on the consolidated financial statements for fiscal years 2014 and 2015.

The total amount of unrecognized tax benefits as of December 31, 2015 and 2014, was $0.4 million and $0.7 million, respectively. Included in the balance as of December 31, 2015 and 2014, were $0.3 million and $0.6 million, respectively, of tax positions that, if recognized, would impact the effective tax rate.

The unrecognized tax benefit reconciliation, excluding penalty and interest, is as follows:

Unrecognized tax benefits at January 1, 2013	$	1,091
Decrease attributable to settlements		(8	)
Increase attributable to tax positions taken during a prior period		43
Decrease attributable to lapse of statute of limitations		(424	)
Unrecognized tax benefits at December 31, 2013		702
Increase (decrease) in unrecognized tax benefits		—
Unrecognized tax benefits at December 31, 2014		702
Decrease attributable to settlements		(174	)
Increase attributable to tax positions taken during a prior period		12
Decrease attributable to lapse of statute of limitations		(140	)
Unrecognized tax benefits at December 31, 2015	$	400

The Company’s policy is not to recognize accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. The Company had approximately $0.1 million and $0.2 million of accrued penalty and interest at both December 31, 2015, and 2014, respectively.

The Company’s 2012 through 2015 tax years remain subject to examination by the Internal Revenue Service for federal tax purposes, in addition to the Company’s 2009 amended tax return. Certain significant state and foreign tax jurisdictions are also either currently under examination or remain open under the statute of limitations and subject to examination for the tax years from 2011 to 2015.

Although the Company believes it has adequately provided for all uncertain tax positions, amounts asserted by taxing authorities could be greater than the Company’s accrued position. Accordingly, additional provisions on federal, state and foreign income tax related matters could be recorded in the future as revised estimates are made or the underlying matters are effectively settled or otherwise resolved. Conversely, the Company could settle positions with the tax authorities for amounts lower than have been accrued. The Company believes it is reasonably possible that, during the next 12 months, the Company’s liability for uncertain tax positions may decrease by approximately $0.1 million.

The Company’s provision for income taxes differs from the anticipated federal statutory rate. Approximate differences between the statutory rate and the Company’s provision are as follows:

	2015			2014			2013
Taxes at statutory rate		35.0	%		35.0	%		35.0	%
State taxes, net of federal benefit		3.9	%		4.2	%		4.2	%
Foreign tax rate differential and U.S. unrepatriated earnings		(0.3	)%		(0.6	)%		(0.3	)%
Other permanent differences		1.9	%		2.0	%		0.7	%
Prior year tax adjustments and changes in unrecognized tax benefits		(1.9	)%		(2.3	)%		(2.1	)%
Tax credits		(0.5	)%		(0.7	)%		(0.7	)%
Taxes at effective rate		38.1	%		37.6	%		36.8	%

Stock Incentive Plans

On June 5, 2015, the Company’s stockholders approved an amendment (the “Amendment”) to the ICF International, Inc. 2010 Omnibus Incentive Plan (as amended, the “Omnibus Plan”). The Amendment, among other items, increased the new shares available for issuance under the Omnibus Plan by 1,540,000 shares from 3,550,000 to 5,090,000 (for an aggregate 5,966,186 shares, which includes shares that remained available under the 2006 Long-Term Equity Incentive Plan when the Omnibus Plan was initially adopted). The Omnibus Plan provides for the granting of options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, cash-based awards, and other stock-based awards to all officers, key employees, and non-employee directors of the Company. Under the terms of the Omnibus Plan, shares awarded that are not stock options or stock appreciation rights, are counted as 1.93 shares deducted for every one share delivered under those awards. Shares awarded that are stock options or stock appreciation rights are counted as a single share deducted from the Omnibus Plan for every one share delivered under those awards. As of December 31, 2015, the Company had approximately 2.7 million shares available to grant under the Amended Plan. CSRSUs have no impact on the shares available for grant under the Omnibus Plan, and have no impact on the calculated shares used in earnings per share calculations.

Starting in the third quarter of 2013, the Company started granting awards of unregistered shares to its non-employee directors on a quarterly basis under its Annual Equity Election program to replace the previous restricted stock awards program. The awards are issued from the Company’s treasury stock and have no impact on the shares available for grant under the Omnibus Plan.

Total compensation expense relating to stock-based compensation was approximately $14.7 million, $13.4 million, and $11.9 million for the years ended December 31, 2015, 2014, and 2013, respectively. As of December 31, 2015, the total unrecognized compensation expense related to non-vested stock awards totaled approximately $17.1 million. These amounts are expected to be recognized over a weighted-average period of 2.1 years. The unrecognized expense related to CSRSUs totaled approximately $11.7 million at December 31, 2015. These costs are expected to be recognized over a weighted-average period of 2.6 years.

The assumptions of employment termination forfeiture rates used in the determination of fair value of stock awards during calendar year 2015 were based on the Company’s historical average from October 2006 through the 12 months preceding the reporting period. The expected annualized forfeiture rates used varied from 4.92% to 8.87%, and the Company does not expect these termination rates to vary significantly in the future.

Stock Options

Option awards are granted with an exercise price equal to the market value of the Company’s common stock on the date of grant. All options outstanding as of December 31, 2015 have a 10-year contractual term. Options generally have a vesting term of three or four years. The Company recorded approximately $1.5 million, $1.9 million, and $1.6 million of compensation expense related to stock options for the years ended December 31, 2015, 2014, and 2013, respectively. There were no options awards granted during 2015. The fair value assumptions using the Black-Scholes-Merton pricing model for awards granted in 2014 were 5.1 years for the expected life, 33.0% for historical volatility, and 1.5% for the risk-free rate of return. The fair value assumptions using the Black-Scholes-Merton pricing model for awards granted in 2013 were 5.4 years for the expected life, 36.8% for historical volatility, and 0.9% for the risk-free rate of return. At December 31, 2015, unrecognized expense related to stock options totaled approximately $0.9 million, and these costs are expected to be recognized over a weighted average period of 1.2 years.

The following table summarizes the changes in outstanding stock options:

Non-employee director awards do not include vesting conditions; thus, there was no unrecognized expense related to these awards as of December 31, 2015, 2014 and 2013. Non-employee director awards are comprised of unregistered shares and have no impact on the shares available for grant under the Omnibus Plan. A summary of the Company’s non-employee director awards granted by fiscal year is presented below.

For the Year ended December 31,	Number of Shares Granted		Weighted- Average Grant Date Fair Value
2013		5,133	$	35.06

2015		18,109	$	35.62

Performance Shares

In the first quarter of 2015, the Company’s Board of Directors approved a performance-based share program (the “Program”) that provides for the issuance of PSAs to its senior management. Under the Program, the number of PSAs that the participant will receive depends on the Company’s achievement of two performance goals during two performance periods. The performance goals under the Program are based on a performance condition (i) the Company’s compounded annual growth rate in earnings per share (“EPS”) during a performance period from January 1, 2015 through December 31, 2016, and a market condition (ii) the Company’s cumulative total shareholder return (“rTSR”) relative to its peer group during a performance period from January 1, 2015 through December 31, 2017. The PSAs will only be eligible to vest following the expiration of the three-year performance period ending on December 31, 2017. Actual shares vested will be subject to both continued employment by the Company (barring certain exceptions allowing for partial performance periods) and actual financial measures achieved. The actual number of shares of common stock that will be issued to each participant at the end of the applicable performance period will be determined by multiplying the award by the product of two percentages, one based on the Company’s EPS performance and a second one based on the Company’s rTSR performance, subject to a minimum and maximum performance level.

The fair value of the awards is estimated on the grant date using a Monte Carlo simulation model due to the market condition for the rTSR component. The fair value assumptions using the Monte Carlo simulation model for awards in 2015 were 0.0% for the dividend yield, 29.3% for historical volatility, and 1.0% for the risk-free rate of return.

During the year ended December 31, 2015, the Company granted approximately 0.1 million PSAs with a grant-date fair value of $44.21 per share. Compensation expense recognized related to PSAs for the year ended December 31, 2015 was $0.7 million. Based on the Company’s current estimate of shares expected to vest, unrecognized compensation expense related to PSAs of $1.9 million as of December 31, 2015 is expected to be recognized over a weighted-average period of approximately 2.0 years.

Earnings Per Share [Text Block]

NOTE

—EARNINGS PER SHARE

Earnings Per Share

EPS is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted EPS considers the potential dilution that could occur if common stock equivalents were exercised or converted into stock. The difference between the basic and diluted weighted-average equivalent shares with respect to the Company’s EPS calculation is due entirely to the assumed exercise of stock options and the vesting and settlement of RSUs.

PSAs are included in the computation of diluted shares only to the extent that the underlying performance conditions (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end of the reporting period were the end of the related performance period and the result would be dilutive under the treasury stock method.

The Company’s PSAs outstanding at December 31, 2015 did not meet the related performance conditions and therefore were excluded from the calculation of diluted EPS. For the years ended December 31, 2015, 2014, and 2013, approximately 167,849, 151,611, and 173,168 anti-dilutive weighted-average shares were excluded from the calculation of EPS because they were anti-dilutive.

The dilutive effect of stock options and RSUs for each period reported is summarized below:

Treasury Stock [Text Block]	NOTE M —SHARE REPURCHASE PROGRAM The Company’s Board of Directors approved a share repurchase plan effective in November 2013 and expiring in November 2015, which authorized the Company to repurchase its outstanding common stock. In March 2015, the plan was amended to increase the amount authorized for repurchases from $35.0 million to $75.0 million, not to exceed the amount allowed under the Credit Facility. Our Credit Facility limits share repurchases to $75.0 million during the duration of the Credit Facility, net of new issuances as defined in the Credit Facility. In the third quarter of 2015, the Company’s Board of Directors approved a new share repurchase plan effective in November 2015 that extends the share repurchase plan through November 2017 and authorizes share repurchases in the aggregate up to $75.0 million, not to exceed the amount allowed under the Credit Facility. Purchases under this program may be made from time to time at prevailing market prices in open market purchases or in privately negotiated transactions pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended and in accordance with applicable insider trading and other securities laws and regulations. The purchases are funded from existing cash balances and/or borrowings, and the repurchased shares are held in treasury and used for general corporate purposes. The timing and extent to which the Company repurchases its shares will depend upon market conditions and other corporate considerations as may be considered in the Company’s sole discretion. During the year ended December 31, 2015, the Company repurchased 638,654 shares totaling $22.3 million under this program. As of December 31, 2015, approximately $39.9 million remained available under the share repurchase plan.

—CONTINGENCIES AND COMMITMENTS

Litigation and Claims

The Company is involved in various legal matters and proceedings arising in the ordinary course of business. While these matters and proceedings cause it to incur costs, including, but not limited to, attorneys’ fees, the Company currently believes that any ultimate liability arising out of these matters and proceedings will not have a material adverse effect on our financial position, results of operations, or cash flows.

Road Home Contract

Although no legal proceeding has been commenced, the Company has received correspondence from the Office of Community Development of the State of Louisiana, claiming that the Company is responsible for the overpayment of Road Home program grant funds to some grant applicants. The State has also indicated that, as it continues to review homeowner grant calculations, it expects to assert additional demands in the future, increasing the aggregate claim amount. The total claim received by the Company to date is approximately $175.3 million. The Company believes this claim has no merit, intends to vigorously defend its position, and has therefore not recorded a liability as of December 31, 2015.

Operating Leases

On March 8, 2010, the Company entered into a new lease that replaced its prior headquarters lease, which was due to expire in October 2012. The new lease was initially for approximately 258,000 square feet, with approximately 72,000 square feet of additional space subsequently added. The lease commenced on April 1, 2010, and will expire on December 31, 2022. Base rent under the agreement is approximately $0.9 million per month with annual escalations fixed at 2.5% per year, yielding a total lease commitment of approximately $150.6 million over the twelve-year term of the lease.

The Company has entered into various other operating leases for equipment and office space. Certain facility leases may contain fixed escalation clauses, certain facility leases require the Company to pay operating expenses in addition to base rental amounts, and nine leases require the Company to maintain letters of credit. Rent expense is recognized on a straight-line basis over the lease term. Rent expense and sub-lease income for operating leases were approximately $40.0 million and less than $0.1 million, respectively, for 2015. Rent expense and sub-lease income for operating leases were approximately $35.8 million and less than $0.1 million, respectively, for 2014. Rent expense for operating leases was approximately $36.5 million for 2013. Future minimum rental payments under all non-cancelable operating leases are as follows:

Compensation and Employee Benefit Plans [Text Block]	NOTE O —EMPLOYEE BENEFIT PLANS Retirement Savings Plan Effective June 30, 1999, the Company established the ICF Consulting Group Retirement Savings Plan (the “Retirement Savings Plan”). The Retirement Savings Plan is a defined contribution profit sharing plan with a cash or deferred arrangement under Section 401(k) of the Internal Revenue Code. Participants in the Retirement Savings Plan are able to elect to defer up to 70% of their compensation subject to statutory limitations, and are entitled to receive 100% employer matching contributions for the first 3% and 50% for the next 2% of their compensation. Contribution expense related to the Retirement Savings Plan for the years ended December 31, 2015, 2014, and 2013, was approximately $13.1 million, $12.3 million, and $12.0 million, respectively. Deferred Compensation Plan Certain key employees of the Company are eligible to defer a specified percentage of their cash compensation by having it contributed to a nonqualified deferred compensation plan. Eligible employees may elect to defer up to 80% of their base salary and up to 100% of performance bonuses, reduced by any amounts withheld for the payment of taxes or other deductions required by law. Participants are at all times 100% vested in their account balances. The Company funds its deferred compensation liabilities by making cash contributions to a Rabbi Trust at the time the salary or bonus being deferred would otherwise be payable to the employee. The liability to plan participants is materially funded at all times and the plan does not have a material net impact on the Company’s results of operations. Employee Stock Purchase Plan The Company has a 2006 Employee Stock Purchase Plan (“ESPP”) under which one million shares have been authorized for issuance. The ESPP allows eligible employees to purchase shares of our common stock through payroll deductions up to $25,000 per calendar year over six-month offering periods at a discount not to exceed 5% of the market value on the date of each purchase period. For the year ended December 31, 2015, 33,339 shares were purchased by employees and 776,512 shares remain available for future issuance. The Company does not recognize compensation expense related to the ESPP.
