We follow generally accepted accounting principles (“GAAP”) set by the Financial Accounting Standards Board (“FASB”). References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification, sometimes referred to as ASC.
Basis of Consolidation
Basis of Consolidation

The consolidated financial statements include the operations of our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Significant Customers and Concentration of Credit Risk
Significant Customers & Concentration of Credit Risk
 
We have a market concentration of revenue in both the automotive sector and financial services & insurance sector. Revenue from the automotive industry accounted for approximately 22%, 19% and 14% of our consolidated revenue for the years ended December 31, 2016, 2015 and 2014, respectively.  In addition, we have a concentration of revenue from a single automotive customer, which accounted for approximately 13% and 12% of our consolidated revenue for the years ended December 31, 2016 and 2015, respectively. As of December 31, 2016 accounts receivable from a single automotive customer totaled $11.6 million, or 11%, of our consolidated accounts receivable balance.
 
Revenue from the financial services and insurance industry accounted for approximately 21%, 21% and 18% of our consolidated revenue for the years ended December 31, 2016, 2015 and 2014, respectively. In addition, we have a concentration of revenue from a single financial services customer, which accounted for approximately 15% and 14% of our consolidated revenue for the years ended December 31, 2016 and 2015, respectively. As of December 31, 2016, billed and unbilled accounts receivable from a single financial services customer totaled $25.4 million, or 18%, of our consolidated accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts balances.

No other single customer accounted for more than 10% of our consolidated revenue in 2016 or consolidated accounts receivable balance as of December 31, 2016.
Cash and Cash Equivalents
Cash
 
We maintain our cash balances in bank accounts at various financial institutions. Outstanding checks which have been issued but not presented to the banks for payment in excess of amounts on deposit may create negative book cash balances. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods. Such negative cash balances are included in accounts payable and accrued expenses and totaled $5.0 million and $3.7 million as of December 31, 2016 and 2015, respectively. Changes in negative book cash balances from period to period are reported as a financing activity in the consolidated statement of cash flows.
Allowance for Doubtful Accounts Receivable
Allowance for Doubtful Accounts Receivable
 
Trade accounts receivable are recorded at invoiced amounts. We evaluate the collectability of trade accounts receivable based on a combination of factors. When we are aware that a specific customer may be unable to meet its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position, we evaluate the need to record a specific reserve for bad debt to reduce the related receivable to the amount we reasonably believe is collectible. We also record reserves for bad debt for all other customers based on a variety of factors, including the length of time the receivables are past due, historical collection experience and trends of past due accounts, write-offs and specific identification and review of past due accounts. Actual collections of trade receivables could differ from management’s estimates due to changes in future economic or industry conditions or specific customers’ financial conditions.
Foreign Currency Translation
Foreign Currency Translation
 
The functional currencies of our international operations are the respective local currencies of the countries in which we operate. The translation of the foreign currency into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using the weighted average exchange rates prevailing during the year. The unrealized gains and losses resulting from such translation are included as a component of comprehensive income. Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in “Other income (expense)" on our Consolidated Statements of Operations.
Revenue Recognition
Revenue Recognition
 
We provide services under time-and-materials, cost-reimbursable, and fixed price (including fixed-fee per transaction) contracts to both government and commercial customers. Each contract has different terms based on the scope, deliverables and complexity of the engagement, requiring us to make judgments and estimates about recognizing revenue. Revenue is recognized as services are performed.
 
Under time-and-materials contracts, as well as certain government cost-reimbursable and certain fixed price contracts, the contractual billing schedules are based on the specified level of resources we are obligated to provide. As a result, for these “level-of-effort” contracts, the contractual billing amount for the period is a measure of performance and, therefore, revenue is recognized in that amount.
 
Revenue under government fixed price contracts is recognized using the percentage-of-completion method. Under the percentage-of-completion method, management estimates the percentage-of-completion based upon costs incurred as a percentage of the total estimated costs.
 
For commercial fixed price contracts which typically involve a discrete project, such as development of training content and materials, design of training processes, software implementation, or engineering projects, the contractual billing schedules are not based on the specified level of resources we are obligated to provide. These discrete projects generally do not contain milestones or other reliable measures of performance. As a result, revenue on these arrangements is recognized using a percentage-of-completion method based on the relationship of costs incurred to total estimated costs expected to be incurred over the term of the contract. We believe this methodology is a reasonable measure of proportional performance since performance primarily involves personnel costs and services provided to the customer throughout the course of the projects through regular communications of progress toward completion and other project deliverables. In addition, the customer typically is required to pay us for the proportionate amount of work and cost incurred in the event of contract termination.
 
When total direct cost estimates exceed revenues, the estimated losses are recognized immediately. The use of the percentage-of-completion method requires significant judgment relative to estimating total contract costs, including assumptions relative to the length of time to complete the project, the nature and complexity of the work to be performed, and anticipated changes in estimated salaries and other costs. Estimates of total contract costs are continuously monitored during the term of the contract, and recorded revenues and costs are subject to revision as the contract progresses. When revisions in estimated contract revenues and costs are determined, such adjustments are recorded in the period in which they are first identified. 
For certain commercial fixed-fee per transaction contracts, such as providing training courses, revenue is recognized during the period in which services are delivered in accordance with the pricing outlined in the contracts.

For certain fixed-fee per transaction and fixed price contracts in which the output of the arrangement is measurable, such as for the shipping of publications and print materials, revenue is recognized when the deliverable is met and the product is delivered based on the output method of performance.  The customer is required to pay for the cost incurred in the event of contract termination.
 
Certain of our fixed price commercial contracts contain revenue arrangements with multiple deliverables.  Revenue arrangements with multiple deliverables are evaluated to determine if the deliverables can be divided into more than one unit of accounting. For contracts determined to have more than one unit of accounting, we recognize revenue for each deliverable based on the revenue recognition policies discussed above.  Within each multiple deliverable project, there is objective and reliable fair value across all units of the arrangement, as discounts are not offered or applied to one deliverable versus another, and the rates bid across all deliverables are consistent.
 
As part of our on-going operations to provide services to our customers, incidental expenses, which are commonly referred to as “out-of-pocket” expenses, are billed to customers, either directly as a pass-through cost or indirectly as a cost estimated in proposing on fixed price contracts. Out-of-pocket expenses include expenses such as airfare, mileage, hotel stays, out-of-town meals and telecommunication charges. Our policy provides for these expenses to be recorded as both revenue and direct cost of services.
 
In connection with the delivery of products, primarily for publications delivered by our Sandy Training & Marketing segment, we incur shipping and handling costs which are billed to customers directly as a pass-through cost.  Our policy provides for these expenses to be recorded as both revenue and direct cost of revenue. 
Contract Related Assets and Liabilities
Contract Related Assets and Liabilities
 
Costs and estimated earnings in excess of billings on uncompleted contracts in the accompanying consolidated balance sheets represent unbilled amounts earned and reimbursable under contracts in progress. These amounts become billable according to the contract terms, which usually consider the passage of time, achievement of milestones or completion of the project. Generally, such unbilled amounts will be billed and collected over the next twelve months.
 
Billings in excess of costs and estimated earnings on uncompleted contracts in the accompanying consolidated balance sheets represent advanced billings to clients on contracts in advance of work performed. Generally, such amounts will be earned and recognized in revenue over the next twelve months.
Comprehensive Income
Comprehensive Income
 
Comprehensive income consists of net income and foreign currency translation adjustments.
Other Current Assets
Other Current Assets
 
Prepaid expenses and other current assets on our consolidated balance sheet include prepaid expenditures for goods or services before the goods are used or the services are received, inventories and work in progress on customer contracts. Prepaid expenses are charged to expense in the periods the benefits are realized. Inventories are stated at lower of cost or market. Provision is made to reduce excess and obsolete inventories to their estimated net realizable value.
Property, Plant and Equipment
Property, Plant and Equipment
 
Property, plant and equipment are carried at cost (or fair value at acquisition date for assets obtained through business combinations). Major additions and improvements are capitalized, while maintenance and repairs which do not extend the lives of the assets are expensed as incurred. Gain or loss on the disposition of property, plant and equipment is recognized in operations when realized.

Depreciation of property, plant and equipment is recognized on a straight-line basis over the following estimated useful lives:
Class of assets
 
Useful life
Buildings and improvements
 
5 to 40 years
Machinery, equipment, and furniture and fixtures
 
3 to 10 years
Leasehold improvements
 
Shorter of asset life or term of lease
Impairment of Long-Lived Assets
Impairment of Long-Lived Assets
 
Long-lived assets, such as property, plant, and equipment, and intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized at the amount by which the carrying amount of the asset exceeds the fair value of the asset. Impairment of long-lived assets is assessed at the lowest level for which there are identifiable cash flows that are independent from other groups of assets. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated.
Goodwill and Intangible Assets
Goodwill and Intangible Assets
 
Our intangible assets include amounts recognized in connection with acquisitions, including customer relationships, tradenames, technology and intellectual property. Intangible assets are initially valued at fair market value using generally accepted valuation methods appropriate for the type of intangible asset. Amortization is recognized on a straight-line basis over the estimated useful life of the intangible assets. Intangible assets with definite lives are reviewed for impairment if indicators of impairment arise. Except for goodwill, we do not have any intangible assets with indefinite useful lives.
 
Goodwill represents the excess of costs over fair value of assets of businesses acquired. We review our goodwill for impairment annually as of October 1 and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. We test goodwill at the reporting unit level.
 
Accounting Standards Update (“ASU”) 2011-08, Testing Goodwill for Impairment (“ASU 2011-08”) permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.  Under ASU 2011-08, an entity is not required to perform step one of the goodwill impairment test for a reporting unit if it is more likely than not that its fair value is greater than its carrying amount.  For our annual goodwill impairment test as of October 1, 2016, we performed a qualitative assessment as permitted by ASU 2011-08 for all of our reporting units and determined that it was more likely than not that the fair values of each of our reporting units exceeded their respective carrying values. For our annual goodwill impairment test as of October 1, 2015, we performed a quantitative step one goodwill impairment test and concluded that the fair values of each of our reporting units exceeded their respective carrying values.
 
If it is determined as a result of the qualitative assessment permitted by ASU 2011-8, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a two-step impairment test is required. In the first step, we compare the fair value of each reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and we are not required to perform further testing. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit's goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit’s assets and liabilities in a manner similar to a purchase price allocation, with any residual fair value allocated to goodwill. If the carrying value of a reporting unit's goodwill exceeds its implied fair value, then we record an impairment loss equal to the difference.
 
Under the two-step impairment test, we determine the fair value of our reporting units using both an income approach and a market approach, and weigh both approaches to determine the fair value of each reporting unit. Under the income approach, we perform a discounted cash flow analysis which incorporates management’s cash flow projections over a five-year period and a terminal value is calculated by applying a capitalization rate to terminal year projections based on an estimated long-term growth rate. The five-year projected cash flows and calculated terminal value are discounted using a weighted average cost of capital (“WACC”) which takes into account the costs of debt and equity. The cost of equity is based on the risk-free interest rate, equity risk premium, industry and size equity premiums and any additional market equity risk premiums as deemed appropriate for each reporting unit. To arrive at a fair value for each reporting unit, the terminal value is discounted by the WACC and added to the present value of the estimated cash flows over the discrete five-year period. There are a number of other variables which impact the projected cash flows, such as expected revenue growth and profitability levels, working capital requirements, capital expenditures and related depreciation and amortization. Under the market approach, we perform a comparable public company analysis and apply revenue and earnings multiples from the identified set of companies to the reporting unit’s actual and forecasted financial performance to determine the fair value of each reporting unit. We evaluate the reasonableness of the fair value calculations of our reporting units by reconciling the total of the fair values of all of our reporting units to our total market capitalization, and adjusting for an appropriate control premium. In addition, we make certain judgments in allocating shared assets and liabilities to determine the carrying values for each of our reporting units.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and determination of appropriate market comparables. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates. In addition, we make certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of our reporting units. The timing and frequency of our goodwill impairment tests are based on an ongoing assessment of events and circumstances that would indicate a possible impairment. We will continue to monitor our goodwill and intangible assets for impairment and conduct formal tests when impairment indicators are present.
Contingent Consideration for Business Acquisitions
Contingent Consideration for Business Acquisitions  
 
Acquisitions may include contingent consideration payments based on future financial measures of an acquired company. Contingent consideration is required to be recognized at fair value as of the acquisition date. We estimate the fair value of these liabilities using an appropriate valuation methodology, typically either an income-based approach or a simulation model, such as the Monte Carlo model, depending on the structure of the contingent consideration arrangement. At each reporting date, the contingent consideration obligation is revalued to estimated fair value and changes in fair value subsequent to the acquisition are reflected in income or expense in the consolidated statements of operations, and could cause a material impact to our operating results. Changes in the fair value of contingent consideration obligations may result from changes in discount periods and rates and changes in the timing and amount of revenue and/or earnings projections.
Other Assets
Other Assets
 
Other assets primarily include an investment in a joint venture and certain software development costs. We account for a 10% interest in a joint venture partnership under the equity method of accounting because significant influence exists due to certain factors, including representation on the partnership’s Management Board and voting rights. We capitalize the cost of internal-use software in accordance with ASC Topic 350-40, Internal-Use Software. These costs consist of payments made to third parties for software development and implementation and are amortized using the straight-line method over their estimated useful lives, typically three to five years.

Income Taxes
Income Taxes
 
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
 
We establish accruals for uncertain tax positions taken or expected to be taken in a tax return when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities that have full knowledge of all relevant information. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Favorable or unfavorable adjustment of the accrual for any particular issue would be recognized as an increase or decrease to income tax expense in the period of a change in facts and circumstances. Interest and penalties related to income taxes are accounted for as income tax expense.
Earnings per Share
Earnings per Share
 
Basic earnings per share (“EPS”) are computed by dividing earnings by the weighted average number of common shares outstanding during the periods.  Diluted EPS reflects the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

Our dilutive common stock equivalent shares consist of stock options and restricted stock units outstanding under our stock-based incentive plans and are computed under the treasury stock method, using the average market price during the period. Performance-based restricted stock unit awards are included in the computation of diluted shares based on the probable outcome of the underlying performance conditions being achieved. The following table presents instruments which were not dilutive and were excluded from the computation of diluted EPS in each period, as well as the weighted average dilutive common stock equivalent shares which were included in the computation of diluted EPS: 
Stock-based Compensation
Stock-Based Compensation
 
Pursuant to our stock-based incentive plans which are described more fully in Note 10, we grant stock options, restricted stock units, performance-based stock units (PSU's) and equity to officers, employees, and members of the Board of Directors.  We compute compensation expense for all equity-based compensation awards issued to employees using the fair-value measurement method. We recognize compensation expense on a straight-line basis over the requisite service period for stock-based compensation awards with both graded and cliff vesting terms. We apply a forfeiture estimate to compensation expense recognized for awards that are expected to vest during the requisite service period, and revise that estimate if subsequent information indicates that the actual forfeitures will differ from the estimate. We recognize the cumulative effect of a change in the number of awards expected to vest in compensation expense in the period of change.  We do not capitalize any material portion of our stock-based compensation.

We recognize compensation expense, net of estimated forfeitures, for PSU's on a straight-line basis over the performance period based on the probable outcome of achievement of the financial targets. At the end of each reporting period, we estimate the number of PSU's expected to vest, based on the probability and extent to which the performance goals will be met, and take into account these estimates when calculating the expense for the period. If the number of shares expected to be earned changes during the performance period, we will make a cumulative adjustment to compensation expense based on the revised number of shares expected to be earned.

 
We estimate the fair value of our stock options on the date of grant using the Black-Scholes option pricing model, which requires various assumptions such as expected term, expected stock price volatility and risk-free interest rate. We estimate the expected term of stock options granted taking into consideration historical data related to stock option exercises. We use historical stock price data in order to estimate the expected volatility factor of stock options granted. The risk-free interest rate for the periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.
Use of Estimates
Use of Estimates
 
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate the estimates used, including but not limited to those related to revenue recognition, the allowance for doubtful accounts receivable, impairments of goodwill and other intangible assets, valuation of intangible assets acquired and contingent consideration liabilities assumed in business acquisitions, valuation of stock-based compensation awards and income taxes.  Actual results could differ from these estimates.
Fair Value Estimates
Fair Value Estimates
 
ASC Topic 820, Fair Value Measurements and Disclosure (“Topic 820”), defines fair value, establishes a market-based framework or hierarchy for measuring fair value, and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The guidance within Topic 820 is applicable whenever another accounting pronouncement requires or permits assets and liabilities to be measured at fair value. The fair value hierarchy prioritizes the inputs used in valuation techniques into three levels as follows:
 
Level 1 – unadjusted quoted prices for identical assets or liabilities in active markets;

Level 2 – quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted market prices that are observable or that can be corroborated by observable market data by correlation; and

Level 3 – unobservable inputs based upon the reporting entity’s internally developed assumptions which market participants would use in pricing the asset or liability.

The carrying value of financial instruments including cash, accounts receivable, accounts payable and short-term borrowings approximate estimated market values because of short-term maturities and interest rates that approximate current rates. In addition, the fair value of our long-term debt approximated its carrying value as of December 31, 2016 as it bears interest at variable rates. Our fair value measurements relate to goodwill, intangible assets and contingent consideration recognized in connection with acquisitions and are valued using Level 3 inputs.
Leases
Leases
 
We lease various office space, machinery and equipment under noncancelable operating leases which have minimum lease obligations.  Many of the leases contain provisions for rent escalations based primarily on increases in real estate taxes and operating costs incurred by the lessor.  Rent expense is recognized in the statements of operations as incurred except for escalating rents, which are expensed on a straight-line basis over the terms of the leases. 
Legal Expenses
Legal Expenses
 
We are involved, from time to time, in litigation and proceedings arising out of the ordinary course of business.  Costs for legal services rendered in the course of these proceedings are charged to expense as they are incurred.

Accounting Standard Issued
Accounting Standards Issued

In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In 2016, the FASB issued accounting standards updates to address implementation issues and to clarify the guidance for identifying performance obligations, licenses and determining if a company is the principal or agent in a revenue arrangement. In August 2015, the FASB deferred the effective date of this ASU to fiscal years beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. ASU 2014-09 permits the use of either a full retrospective or a modified retrospective adoption method. We plan to adopt the standard effective January 1, 2018 and we currently anticipate using the full retrospective method. Based on our assessment to date, we believe the new standard could result in a change in revenue recognition on certain fixed price projects from a proportional performance method, where revenue is currently recognized over contract performance, to a completed contract method, where revenue would be recognized upon completion of our performance obligations. This change could result in a shift in the timing of revenue recognition, causing quarter to quarter revenue fluctuations. We are continuing to evaluate ASU 2014-09 and the impact of its adoption on our consolidated financial statements and plan to provide additional information at a future date.

In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet as a right-of-use asset and a lease liability. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. We believe adoption of this standard will have a significant impact on our consolidated balance sheets because we will need to recognize substantially all of our operating leases as right-of-use assets and lease liabilities on our balance sheet. Although we have not completed our assessment, we do not expect the adoption of ASU 2016-02 to materially change the recognition and measurement of lease expense within the consolidated statements of operations.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718) ("ASU 2016-09"). The standard is intended to simplify several areas of accounting for share-based compensation arrangements. Under ASU 2016-09, companies will no longer record excess tax benefits and tax deficiencies to additional paid-in capital (APIC) on the settlement of awards. Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement and APIC pools will be eliminated. ASU 2016-09 also requires companies to make an accounting policy election on whether to account for forfeitures on share-based payments by 1) recognizing forfeitures as they occur; or 2) estimating the number of awards expected to be forfeited and periodically adjusting the estimate, as is currently required. ASU 2016-09 also clarifies the statement of cash flows presentation for certain components of share-based awards. The standard is effective for annual and interim reporting periods of public companies beginning after December 15, 2016, although early adoption is permitted. We adopted ASU 2016-09 on January 1, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements. However, it could result in volatility in income tax expense in future periods as a result of the change in accounting for excess tax benefits on the settlement of awards.
