Accounting Policies [Abstract]

1. Description of Business and Summary of Significant Accounting Policies

Description of Business

FTI Consulting, Inc. including its consolidated subsidiaries (collectively, the “Company,” “we,” “our” or “FTI Consulting”), is a global business advisory firm dedicated to helping organizations manage change, mitigate risk and resolve disputes: financial, legal, operational, political and regulatory, reputational and transactional. Individually, each of our segments and practices is staffed with experts recognized for the depth of their knowledge and a track record of making an impact. Collectively, FTI Consulting offers a comprehensive suite of services designed to assist clients across the business cycle, from proactive risk management to rapid response to unexpected events and dynamic environments. We operate through five reportable segments: Corporate Finance & Restructuring, Forensic and Litigation Consulting, Economic Consulting, Technology and Strategic Communications.

Accounting Principles

Our financial statements are prepared in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The consolidated financial statements include the accounts of FTI Consulting and all of our subsidiaries. All intercompany transactions and balances have been eliminated. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.

Foreign Currency

Results of operations for our non-U.S. subsidiaries are translated from the designated functional currency to the reporting currency of the U.S. dollar. Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates. Resulting net translation adjustments are recorded as a component of stockholders’ equity in “Accumulated other comprehensive income (loss).”

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 “Interest income and other” on our Consolidated Statements of Comprehensive Income. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Due to the inherent uncertainty involved in making those assumptions, actual results could differ from those estimates. The most significant estimates made and assumptions used are the determination of the allowance for doubtful accounts and unbilled services, the assessment of the recoverability of goodwill and intangible assets and realization of deferred tax assets, the valuation of share-based compensation and the fair value of acquisition-related contingent consideration. Management bases its estimates on historical trends, current experience and other assumptions that it believes are reasonable.

Concentrations of Risk

We do not have a single customer that represents ten percent or more of our consolidated revenues. We derive the majority of our revenues from providing professional services to clients in the U.S. For the year ended December 31, 2016, we derived approximately 28% of our consolidated revenues from the work of professionals who are assigned to locations outside of the U.S. We believe that the geographic and industry diversity of our customer base throughout the U.S. and internationally minimizes the risk of incurring material losses due to concentrations of credit risk.

Revenue Recognition

Revenues are recognized when persuasive evidence of an arrangement exists, the related services are provided, the price is fixed or determinable and collectability is reasonably assured. If, at the outset of an arrangement, we determine that the arrangement fee is not fixed or determinable, revenues are deferred until all criteria for recognizing revenues are met. Provisions are recorded for the estimated realization adjustments on all engagements, including engagements for which fees are subject to review by bankruptcy courts and other regulatory institutions. If the client is in bankruptcy, fees for our services may be subject to approval by the court. In some cases, a portion of the fees to be paid to us by a client is required by a court to be held until completion of our work and final fee settlements have been negotiated. We make a determination whether to record all or a portion of such holdback as revenues prior to collection on a case-by-case basis.

We generate the majority of our revenues from providing professional services under four types of billing arrangements: time and expense, fixed fee, performance based and unit based.

Time and expense billing arrangements require the client to pay based on the number of hours worked by our revenue-generating professionals at contractually agreed-upon rates. We recognize revenues for our professional services rendered under time and expense engagements based on the hours incurred at agreed-upon rates, including discounts, as work is performed. In some cases, time and expense arrangements are subject to a cap, in which case we assess work performed on a periodic basis to ensure that the cap has not been exceeded.

Fixed fee billing arrangements require the client to pay a pre-established fee in exchange for a predetermined set of professional services. Generally, the client agrees to pay a fixed fee every month over the specified contract term. These contracts are for varying periods and generally permit the client to cancel the contract before the end of the term. We recognize revenues for our professional services rendered under these fixed fee billing arrangements monthly over the specified contract term or, in certain cases, revenues are recognized on the proportional performance method of accounting based on the ratio of labor hours incurred to estimated total labor hours, which we consider to be the best available indicator of the pattern and timing in which such contract obligations are fulfilled.

Performance based or contingent billing arrangements require the client to pay fees based on the attainment of contractually defined objectives. Often this type of arrangement supplements a time and expense or fixed fee engagement, where payment of a performance based fee is deferred until the conclusion of the matter or upon the achievement of performance based criteria. We do not recognize revenues under performance based billing arrangements until all related performance criteria are met and collection of the fee is reasonably assured.

Unit based revenues, predominantly in our Technology segment, are based on either the amount of data stored or processed, the number of concurrent users accessing the information, or the number of pages or images processed for a client. We recognize revenues for our professional services rendered under unit based engagements as the services are provided based on agreed-upon rates. Revenues from hosting fees are recognized based on the units used over the term of the hosting agreement. Additionally, we may provide client incentives in the form of volume fee discounts, which are recorded as a reduction of revenues.

We also generate certain revenues from software licenses and maintenance, predominantly in our Technology segment. We have vendor-specific objective evidence of fair value for support and maintenance separate from software for the majority of our products. Accordingly, when licenses of certain offerings are included in an arrangement with support and maintenance, we recognize the license revenues upon delivery of the license and recognize the support and maintenance revenues over the term of the maintenance service period. Our software license agreements generally do not include acceptance provisions. If an arrangement allows for customer acceptance of the software, we defer revenues until the earlier of customer acceptance or when the acceptance provisions lapse.

Some clients pay us a retainer before we begin work for them. We hold retainers on deposit until we have completed the work. We generally apply these retainers to final billings and refund any excess over the final amount billed to clients, as appropriate.

Reimbursable expenses, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues, and an equivalent amount of reimbursable expenses is included in costs of services in the period in which the expense is incurred. Revenues recognized, but not yet billed to clients, have been recorded as “Unbilled receivables” in the Consolidated Balance Sheets.

Direct Cost of Revenues

Direct cost of revenues consists primarily of billable employee compensation and related payroll benefits, the cost of contractors assigned to revenue-generating activities and direct expenses billable to clients. Direct cost of revenues also includes depreciation expense on the equipment of our Technology segment that is used to host and process client information, as well as amortization of software. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs.

Share-Based Compensation

Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period or performance period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date.

We use the Black-Scholes pricing model to determine the fair value of stock options on the dates of grant. The Black-Scholes pricing model requires the development of assumptions including volatility and expected term, which are based on our historical experience. The risk-free interest rate is based on the term of U.S. Treasury interest rates that is consistent with the expected term of the share-based award.

The fair value of restricted share awards and restricted stock units are measured based on the closing price of the underlying stock on the dates of grant. The fair value of performance share units that contain market-based vesting conditions are measured using a Monte Carlo pricing model. The compensation cost of performance stock units is based on the grant date fair value and is not subsequently reversed if it is later determined that the market condition is unlikely to be met or is expected to be lower than originally expected.

For all our share-based awards, we estimate the expected forfeiture rate and recognize expense only for those shares expected to vest. We estimate the forfeiture rate based on historical experience. Groups of share-based award holders that have similar historical behavior with regard to option exercise timing and forfeiture rates are considered separately for valuation and attribution purposes. Forfeitures are estimated at the time an award is granted and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Research and Development

Research and development costs related to software development are expensed as incurred. When we have determined that technological feasibility for our software products is reached, development costs related to the project are capitalized until such products are available for general release to customers as discussed in “Capitalized Software to Be Sold, Leased or Otherwise Marketed.” Research and development expense related to software development totaled $17.5 million, $19.5 million and $19.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, and are included in “Selling, general and administrative expenses” on the Consolidated Statements of Comprehensive Income.

Advertising Costs

Advertising costs consist of marketing, advertising through print and other media, professional event sponsorship and public relations. These costs are expensed as incurred. Advertising costs totaled $15.9 million for the year ended December 31, 2016, $18.2 million for the year ended December 31, 2015 and $20.7 million for the year ended December 31, 2014.

Acquisition-Related Contingent Consideration

The fair value of acquisition-related contingent consideration is estimated at the acquisition date utilizing a probability weighted estimated cash flow stream adjusted for the expected timing of each payment. Subsequent to the acquisition date, on a quarterly basis, the contingent consideration liability is remeasured at current fair value with any changes recorded in earnings. Accretion expense is recorded to adjust the discounted value of acquisition contingent consideration liabilities to their present value. Any remeasurement gain or loss and the accretion expense related to the increase in the net present value of the contingent liability are included in “Acquisition-related contingent consideration” on our Consolidated Statements of Comprehensive Income.

Income Taxes

Our income tax provision consists principally of U.S. federal, state and international income taxes. We generate income in a significant number of states located throughout the U.S., as well as foreign countries in which we conduct business. Our effective income tax rate may fluctuate due to a change in the mix of earnings between higher and lower state or country tax jurisdictions and the impact of non-deductible expenses. Additionally, we record deferred tax assets and liabilities using the asset and liability method of accounting, which requires us to measure these assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of temporary differences, projected future taxable income, tax planning strategies and results of recent operations.

Cash Equivalents and Short-Term Investments

Cash equivalents consist of highly liquid short-term investments, principally money market funds, commercial paper and certificates of deposit with maturities of three months or less at the time of purchase. In addition, we may invest in short-term investments with maturities greater than three months, consisting primarily of certificates of deposit and treasury bills. Any short-term investments are classified as available-for-sale and carried at fair value, based on quoted market prices or other readily available market information. Short-term investments are included in “Prepaid assets and other current assets” on our Consolidated Balance Sheets.

Allowance for Doubtful Accounts and Unbilled Services

We maintain an allowance for doubtful accounts and unbilled services for estimated losses resulting from potential fee reductions negotiated by clients or imposed by bankruptcy courts or other regulatory agencies, the inability of clients to pay our fees, as well as from disputes that affect our ability to fully collect our billed accounts receivable. Even if a bankruptcy court approves our services, the court has the discretion to require us to refund all or a portion of our fees due to the outcome of the case or a variety of other factors. We estimate the allowance for all receivable risks by reviewing the status of each matter and recording reserves based on our experience and knowledge of the particular client and historical collection patterns. However, our actual experience may vary significantly from our estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay our fees, or bankruptcy courts require us to refund certain fees, we may need to record additional allowances or write-offs in future periods. This risk related to a client’s non-payment may be mitigated to the extent that we receive a retainer from some of our clients prior to performing services.

We record adjustments to the allowance for doubtful accounts and unbilled services as a reduction in revenues when there are changes in estimates of fee reductions that may be imposed by bankruptcy courts and other regulatory institutions for both billed and unbilled receivables. The allowance for doubtful accounts and unbilled services is also adjusted after the related work has been billed to the client and we discover that collectability is not reasonably assured. These adjustments are recorded to “Selling, general and administrative expenses” on the Consolidated Statements of Comprehensive Income and totaled $8.9 million, $15.6 million and $18.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Property and Equipment

We record property and equipment, including improvements that extend useful lives, at cost, while maintenance and repairs are charged to operations as incurred. We calculate depreciation using the straight-line method based on estimated useful lives ranging from three to seven years for furniture, equipment and internal use software. We amortize leasehold improvements over the shorter of the estimated useful life of the asset or the lease term. We capitalize costs incurred during the application development stage of computer software developed or obtained for internal use. Capitalized software developed for internal use is classified within furniture, equipment and software and is amortized over the estimated useful life of the software, which is generally three years.

Notes Receivable from Employees

Notes receivable from employees principally include unsecured general recourse forgivable loans and retention payments, which are provided to attract and retain certain of our senior employees and other professionals. Generally, all of the principal amount and accrued interest of the forgivable loans we make to employees and other professionals will be forgiven according to the stated terms of the loan agreement, provided that the professional is providing service to the Company on the forgiveness date, and upon other specified events, such as death or disability. Professionals who terminate their employment or services with us prior to the end of the forgiveness period are required to repay the outstanding, unforgiven loan balance and any accrued but unforgiven interest. If the termination was by the Company without cause or by the employee with good reason, or, subject to certain conditions, if the employee terminates his or her employment due to retirement or non-renewal of his or her employment agreement, the loan may be forgiven or continue to be forgivable, in whole or in part. We amortize forgivable loans ratably over the requisite service period, which ranges from a period of one to 10 years. The amount of expense recognized at any date must at least equal the portion of the principal forgiven on the forgiveness date.

Goodwill and Other Intangible Assets

Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired. Other intangible assets may include trade names, customer relationships, non-competition agreements and software.

We test our goodwill and other indefinite-lived intangible assets for impairment annually as of the first day of the fourth quarter or whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Factors we consider important that could trigger an interim impairment review include, but are not limited to, the following:

•

significant underperformance relative to expected historical or projected future operating results;

•

a significant change in the manner of our use of the acquired asset or the strategy for our overall business;

•

a significant market decline related to negative industry or economic trends; and/or

•

our market capitalization relative to net carrying value.

We assess our goodwill for impairment using a fair value approach at the reporting unit level. A reporting unit is an operating segment or a business one level below that operating segment if discrete financial information is available and regularly reviewed by the chief operating decision makers. When available and as appropriate in order to estimate fair values, we use market multiples derived from a set of guideline companies and/or guideline transactions (market approaches), discounted cash flows (an income approach) or a combination of appropriately weighted income and market approaches.

Intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate an asset’s carrying value may not be recoverable. We amortize our acquired finite-lived intangible assets on a straight-line basis over periods ranging from one to 15 years.

Impairment of Long-Lived Assets

We review long-lived assets such as property and equipment and finite-lived intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans or changes in anticipated future cash flows. If an impairment indicator is present, we evaluate recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. We group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, we estimate the fair value of the asset group to determine whether an impairment loss should be recognized.

Capitalized Software to Be Sold, Leased or Otherwise Marketed

We expense costs for software products that will be sold, leased or otherwise marketed until technological feasibility has been established. Thereafter, eligible software development costs are capitalized and subsequently reported at the lower of unamortized cost or net realizable value. Capitalized costs are amortized based on current and future revenues for each product with an annual minimum equal to the straight-line amortization over the remaining estimated economic life of the product. We classify software products to be sold, leased or otherwise marketed as noncurrent “Other assets” on our Consolidated Balance Sheets. Unamortized capitalized software costs were $16.6 million and $17.6 million as of December 31, 2016 and 2015, respectively. Amortization expense for capitalized software costs was $12.0 million, $6.5 million and $6.7 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Leases

We lease office space and equipment under non-cancelable operating leases. The leases normally provide for the payment of minimum annual rentals and may include scheduled rent increases. Some leases include provisions for renewal options of up to five years. Some of our leases for office space contain provisions whereby the future rental payments may be adjusted for increases in operating expenses above specified amounts.

We recognize rent expense under operating leases on a straight-line basis over the non-cancelable lease term. For leases with scheduled rent increases, this treatment results in a deferred rent liability, which is classified within “Other liabilities” on the Consolidated Balance Sheets. Lease inducements, such as tenant improvement allowances, cash inducements and rent abatements, are amortized on a straight-line basis over the life of the lease. Unamortized lease inducements are also included in deferred rent. Deferred rent totaled $41.9 million and $44.9 million for the years ended December 31, 2016 and 2015, respectively.

Billings in Excess of Services Provided

Billings in excess of services provided represent amounts billed to clients, such as retainers, in advance of work being performed. Clients may make advance payments, which are held on deposit until completion of work or are applied at predetermined amounts or times. Excess payments are either applied to final billings or refunded to clients upon completion of work. Payments in excess of related accounts receivable and unbilled receivables are recorded as billings in excess of services provided within the liabilities section of our Consolidated Balance Sheets.

Accounting Changes And Error Corrections [Abstract]

New Accounting Standards

2. New Accounting Standards

In October 2016, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which removes the prohibition against immediate recognition of current and deferred income tax effects on intra-entity transfers of assets other than inventory. This standard is effective January 1, 2019, although early adoption is permitted as early as January 1, 2017. We have not yet determined the impact that the adoption of this guidance will have on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how cash receipts and cash payments are classified in the statement of cash flows. This standard is effective January 1, 2018, although early adoption is permitted. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This standard makes several modifications to Topic 718, including the accounting for forfeitures, employer tax withholding on share-based compensation, income tax consequences, and clarifies the statement of cash flows presentation for certain components of share-based awards, all of which are intended to simplify various aspects of the accounting for share-based compensation. The ASU will require that the difference between the actual tax benefit realized upon option exercise or restricted share or restricted stock unit release and the tax benefit recorded based on the fair value of the stock award at the time of grant (the “excess tax benefits”) to be reflected as a reduction of the current period provision for income taxes with any shortfall recorded as an increase in the tax provision rather than as a component of changes to additional paid-in capital. The ASU will also require the excess tax benefit or detriment realized to be reflected as operating cash flows rather than financing cash flows. The standard is effective beginning January 1, 2017. If we had adopted this ASU on January 1, 2015, the provision for income taxes would have increased by $2.1 million, $2.0 million and $1.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. The actual benefit or detriment realized in future periods cannot be precisely estimated and will vary based on the timing and relative value realized for future share-based transactions.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), that replaces existing lease guidance. Under this ASU, leases will be required to record right-of-use assets and corresponding lease liabilities on the balance sheet. This guidance is effective beginning January 1, 2019. The new standard is required to be applied with a modified retrospective approach to each prior reporting period presented. We have not yet determined the impact that the adoption of this guidance will have on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Under this ASU and subsequently issued amendments, revenues are recognized at the time when goods or services are transferred to a customer in an amount that reflects the consideration it expects to receive in exchange for those goods or services. Companies may use either a full retrospective or a modified retrospective approach to adopt this ASU. Based on our continuing assessment of the potential impact of this standard, we believe the adoption of this standard may impact the following:

•

Engagements that contain performance-based arrangements, in which we earn a success or completion fee when and if certain predefined outcomes occur;

•

Engagements with fixed-fees that have multiple performance obligations; and

•

Engagements that include discounting arrangements.

We have not completed our assessment and have not yet determined whether the impact of the adoption of this standard on our consolidated financial statements will be material. We will adopt this standard on January 1, 2018 but have not yet concluded on a transition approach. We expect to complete our assessment process, including selecting a transition method for adoption during the first half of 2017.

There were no forfeitures related to special charges for the year ended December 31, 2016. (See Note 4, “Special Charges” for information related to the special charges).

Stock Options

We use the Black-Scholes option-pricing model to value our option grants using the assumptions in the following table.

	Year Ended December 31,
Assumptions	2016		2015		2014

A summary of our stock option activity during the year ended December 31, 2016 is presented below. The aggregate intrinsic value in the table below represents the total pre-tax intrinsic value, which is calculated as the difference between the closing price of our common stock on the last trading day of 2016 and the exercise price, multiplied by the number of in-the-money options that would have been received by the option holders had all option holders exercised their options on December 31, 2016. The aggregate intrinsic value changes based on fluctuations in the fair market value per share of our common stock.

Cash received from option exercises for the years ended December 31, 2016, 2015 and 2014 was $27.3 million, $21.1 million and $11.3 million, respectively. The actual tax benefit realized from stock options exercised totaled $4.8 million, $5.5 million and $1.9 million for the years ended December 31, 2016, 2015 and 2014, respectively.

The intrinsic value of stock options exercised is the amount by which the market value of our common stock on the exercise date exceeds the exercise price. The total intrinsic value of stock options exercised for the years ended December 31, 2016, 2015 and 2014 was $6.9 million, $8.1 million and $4.4 million, respectively.

Financial Instruments

8. Financial Instruments

We consider the recorded value of our certain financial assets and liabilities, which consist primarily of cash equivalents, accounts receivable and accounts payable, to approximate the fair value of the respective assets and liabilities as of December 31, 2016 and 2015, based on the short-term nature of the assets and liabilities. We determine the fair value of our long-term debt primarily based on quoted market prices for our 6% Senior Notes Due 2022 (the “2022 Notes”) as of December 31, 2016. The fair value of our borrowings on our senior secured bank revolving credit facility (“Senior Bank Credit Facility”) approximates the carrying amount. The fair value of our long-term debt is classified within Level 2 of the fair value hierarchy because it is traded in less active markets.

The following table presents the carrying amounts and estimated fair values of our other financial instruments as of December 31, 2016 and 2015.

	December 31,
	2016				2015
	Carrying		Estimated		Carrying		Estimated
	Amount		Fair Value		Amount		Fair Value
Liabilities
Acquisition-related contingent consideration, including current portion⁽¹⁾	$	5,692	$	5,692	$	4,394	$	4,394
Long-term debt		370,000		382,750		500,000		513,500
Total	$	375,692	$	388,442	$	504,394	$	517,894

⁽¹⁾	The short-term portion is included in “Accounts payable, accrued expenses and other” and the long-term portion is included in “Other liabilities” on the Consolidated Balance Sheets.

We estimate the fair value of acquisition-related contingent consideration using a probability-weighted discounted cash flow model. This fair value measure is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Fair value measurements characterized within Level 3 of the fair value hierarchy are measured based on unobservable inputs that are supported by little or no market activity and reflect our own assumptions in measuring fair value.

The significant unobservable inputs used in the fair value measurements of our acquisition-related contingent consideration are our measures of the future profitability and related cash flows and discount rates. Significant increases (decreases) in any of these inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumptions used for the discount rates is accompanied by a directionally opposite change in the fair value measurement, and a change in the assumptions used for the future cash flows is accompanied by a directionally similar change in the fair value measurement. The fair value of the contingent consideration is reassessed at each reporting period by the Company based on additional information as it becomes available.

Any change in the fair value of an acquisition’s contingent consideration liability results in a remeasurement gain or loss that is recorded as income or expense, respectively, and is included in “Acquisition-related contingent consideration” on the Consolidated Statements of Comprehensive Income. During the year ended December 31, 2016, we recorded a $1.4 million expense related to the increase in the liability for future expected contingent consideration payments. During the year ended December 31, 2015 and 2014, we recorded a $1.9 million and $2.7 million gain related to the change in fair value of future contingent consideration payments, respectively.

Accretion expense for acquisition-related contingent consideration totaled $0.8 million, $0.7 million and $1.0 million for the year ended December 31, 2016, 2015 and 2014, respectively, and is included within “Acquisition-related contingent consideration” in the Consolidated Statements of Comprehensive Income.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Other Intangible Assets

Other intangible assets with finite lives are amortized over their estimated useful lives. We recorded amortization expense of $10.3 million, $11.7 million and $15.5 million during the years ended December 31, 2016, 2015 and 2014, respectively. Based solely on the amortizable intangible assets recorded as of December 31, 2016, we estimate amortization expense to be $9.4 million in 2017, $7.9 million in 2018, $7.3 million in 2019, $7.1 million in 2020, $6.5 million in 2021 and an aggregate of $8.3 million in years after 2021. Actual amortization expense to be reported in future periods could differ from these estimates as a result of new intangible asset acquisitions, changes in useful lives or other relevant factors or changes.

There were no current portions of long-term debt as of December 31, 2016 and 2015.

6% Senior Notes Due 2022. The 2022 Notes have been registered with the Securities and Exchange Commission. Cash interest is payable semiannually beginning on May 15, 2013 at a rate of 6% per year. The 2022 Notes will mature on November 15, 2022. The 2022 Notes are guaranteed, with certain exceptions, by our existing and future domestic subsidiaries. The 2022 Notes and the guarantees are our and the guarantors’ general unsecured senior obligations. The indebtedness evidenced by the 2022 Notes and the guarantees (i) rank equally in right of payment with all of FTI Consulting, Inc.’s and the guarantors’ existing and future senior indebtedness, (ii) rank senior in right of payment to any existing and future subordinated indebtedness, (iii) are effectively junior to all of FTI Consulting, Inc.’s and the guarantors’ secured debt, including borrowings under the Senior Bank Credit Facility, to the extent of the value of the collateral securing such indebtedness, and (iv) are structurally subordinated to all existing and future indebtedness and other liabilities of any current and future non-guarantor subsidiaries (other than indebtedness and liabilities owed to FTI Consulting, Inc. or one of its guarantor subsidiaries).

At any time prior to November 15, 2017, we may redeem the 2022 Notes, in whole or in part, at a price equal to 100% of the principal amount plus an applicable “make-whole” premium and accrued and unpaid interest, if any, to the redemption date. The 2022 Notes are subject to redemption at our option, in whole or in part, at any time after November 15, 2017, upon not less than 30 nor more than 60 days prior notice at the following redemption prices (expressed as percentages of the principal amount to be redeemed) set forth below plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

Year	Redemption Price
2017		103.000	%
2018		102.000	%
2019		101.000	%
2020 and thereafter		100.000	%

Debt issue costs of approximately $7.6 million were capitalized and are being amortized over the term of the 2022 Notes, which approximates the effective interest method.

6³/₄% Senior Notes Due 2020. On August 14, 2015, the Company commenced a cash tender offer for any and all of the 6 ¾% Senior Notes Due 2020 (the “2020 Notes”) for a price equal to $1,037.88 per $1,000 principal amount plus accrued interest (the “Tender Offer”). The Tender Offer expired on August 27, 2015, and on August 28, 2015, we retired an aggregate of $192.9 million principal amount of the 2020 Notes pursuant to the Tender Offer. On September 1, 2015, the Company issued a notice of redemption for the balance of $207.1 million principal amount of 2020 Notes that remained outstanding after the Tender Offer, with a redemption date of October 1, 2015. On September 23, 2015, pursuant to the terms of the 2020 Note Indenture, we satisfied and discharged the $207.1 million principal amount of the 2020 Notes that remained outstanding by irrevocably depositing with a trustee, prior to the redemption date, sufficient funds to repurchase all such 2020 Notes at a redemption price of $1,033.75 (plus accrued and unpaid interest through September 30, 2015) for each $1,000 aggregate principal amount. The 2020 Notes were subsequently redeemed by the trustee on October 1, 2015.

We recognized a loss on our early extinguishment of debt of $19.6 million, consisting primarily of a redemption premium of $14.3 million and a $4.9 million non-cash write-off of unamortized deferred financing costs. This loss was recorded in “Loss on early extinguishment of debt” within the 2015 Consolidated Statements of Comprehensive Income.

Senior Bank Credit Facility. On June 26, 2015, we entered into a credit agreement (the “2015 Credit Agreement”), which effectively amended and extended our prior credit agreement, dated November 27, 2012 (the “2012 Credit Agreement”). The 2012 Credit Agreement provided for a five-year $350.0 million senior secured revolving line of credit maturing on November 27, 2017. The 2015 Credit Agreement provides for a $550.0 million senior secured revolving line of credit maturing on September 26, 2020. We did not incur any early termination or prepayment penalties in connection with the replacement of the 2012 Credit Agreement. At the Company’s option, borrowings under the Senior Bank Credit Facility will bear interest at either one-, two- or three-month LIBOR or an alternative base rate, in each case plus the applicable margin. The applicable margin will fluctuate between 1.375% per annum and 2.00% per annum, in the case of LIBOR borrowings, or between 0.375% per annum and 1.00% per annum, in the case of base rate borrowings, in each case, based upon the Company’s Consolidated Total Leverage Ratio (as defined in the 2015 Credit Agreement) at such time.

Under the Senior Bank Credit Facility, we are required to pay a commitment fee rate that fluctuates between 0.25% and 0.35% per annum and the letter of credit fee rate that fluctuates between 1.375% and 2.00% per annum, in each case, based upon the Company’s Consolidated Total Leverage Ratio.

Under the Senior Bank Credit Facility, the lenders have a security interest in substantially all of the existing and after-acquired assets of FTI Consulting, Inc. and substantially all of our domestic subsidiaries. Subject to certain conditions, at any time prior to maturity, we will be able to invite existing and new lenders to increase the size of the Senior Bank Credit Facility under the 2015 Credit Agreement or provide new term loans under the 2015 Credit Agreement, in each case, up to a maximum of $100.0 million plus unlimited amounts as long as the effect of the new increase does not cause the Consolidated Total Leverage Ratio to be greater than 3.50 to 1.00.

The 2015 Credit Agreement governing our Senior Bank Credit Facility and the indenture governing our 2022 Notes contain covenants that, among other things, limit our ability to incur additional indebtedness; create liens; pay dividends on our capital stock; make distributions or repurchases of our capital stock or make specified other restricted payments; consolidate, merge or sell assets or engage in sale-leasebacks; guarantee obligations of other entities and our foreign subsidiaries; make investments and loans; enter into transactions with affiliates or related persons, repay, redeem or purchase certain indebtedness (or modify the terms thereof), make material changes to accounting and reporting practices; and engage in any business other than consulting-related businesses or substantially related, complimentary or incidental businesses. In addition, the 2015 Credit Agreement governing our Senior Bank Credit Facility includes financial covenants that require us (i) not to exceed a maximum consolidated total leverage ratio (the ratio of total funded debt to adjusted EBITDA) and (ii) to exceed a minimum consolidated interest coverage ratio (the ratio of adjusted EBITDA less capital expenditures and cash taxes to cash interest expense).

There were $70.0 million in borrowings outstanding under the Company’s Senior Bank Credit Facility as of December 31, 2016. The Company has classified these borrowings as long-term debt in the accompanying Consolidated Balance Sheets as the Company has the intent and ability, as supported by availability under the 2015 Credit Agreement, to refinance these borrowings for more than one year from the balance sheet date. Additionally, $0.7 million of the borrowing limit was used (and, therefore, unavailable) as of December 31, 2016 for letters of credit.

There were $4.3 million, $5.5 million and $2.8 million of unamortized debt issue costs related to Senior Bank Credit Facility as of December 31, 2016, 2015 and 2014, respectively. These amounts were included in “Other assets” on our Consolidated Balance Sheets.

As of December 31, 2016, we have not provided for deferred taxes on $81.7 million of the undistributed non-U.S. subsidiary earnings that are considered permanently invested. If these earnings were distributed in the form of dividends or otherwise, the distributors would be subject to U.S. federal income tax of approximately $28.6 million.

As of December 31, 2016 and 2015, the Company believed certain deferred tax assets principally associated with foreign net operating loss, foreign tax credit carryforwards and other related foreign balance sheet accounts, which can be carried forward for periods ranging from 20 years to indefinite, would expire unused based on updated forward-looking financial information. Therefore, valuation allowances of $18.9 million and $13.2 million were recorded against the Company’s net deferred tax assets as of December 31, 2016 and 2015, respectively.

As of December 31, 2016, we have not recorded a $15.4 million deferred tax liability related to the tax basis difference in the investment in our foreign subsidiaries as the investment is considered permanent in duration.

We file numerous consolidated and separate income tax returns in the U.S. federal jurisdiction and in many city, state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations for years prior to 2012. We are also no longer subject to state and local or foreign tax examinations by tax authorities for years prior to 2010.

Our liability for uncertain tax positions was $2.7 million and $8.1 million as of December 31, 2016 and 2015, respectively. The $5.4 million decrease in our liability for uncertain tax positions was primarily due to closure of certain income tax audits. As of December 31, 2016, our accrual for the payment of tax-related interest and penalties was not material.

Segment Reporting [Abstract]

Segment Reporting

17. Segment Reporting

We manage our business in five reportable segments: Corporate Finance & Restructuring, Forensic and Litigation Consulting, Economic Consulting, Technology and Strategic Communications.

Our Corporate Finance & Restructuring segment focuses on the strategic, operational, financial and capital needs of our clients around the world and delivers a wide range of distressed and non-distressed practice offerings. Our distressed practice offerings include corporate restructuring (and bankruptcy) and interim management services. Our non-distressed practice offerings include financings, mergers and acquisitions (“M&A”), M&A integration, valuations and tax advice, as well as financial, operational and performance improvement services.

Our Forensic and Litigation Consulting segment provides law firms, companies, government clients and other interested parties with multidisciplinary, independent dispute advisory, investigations, data analytics, forensic accounting, business intelligence and risk mitigation services, as well as interim management and performance improvement services for our health solutions practice clients.

Our Economic Consulting segment provides law firms, companies, government entities and other interested parties with analysis of complex economic issues for use in legal, regulatory and international arbitration proceedings, strategic decision making and public policy debates in the U.S. and around the world.

Our Technology segment offers a comprehensive portfolio of information governance and e-discovery software, services and consulting support to companies, law firms, courts and government agencies worldwide. Our services allow our clients to control the risk and expense of e-discovery events more confidently, as well as manage their data in the context of compliance and risk.

Our Strategic Communications segment designs and executes communications strategies for management teams and boards of directors to help them seize opportunities, manage financial, regulatory and reputational challenges, navigate market disruptions, articulate their brand, stake a competitive position, and preserve and grow their operations.

We evaluate the performance of our operating segments based on Adjusted Segment EBITDA. We define Adjusted Segment EBITDA as a segment’s share of consolidated operating income before depreciation, amortization of intangible assets, remeasurement of acquisition-related contingent consideration, special charges and goodwill impairment charges. We define Total Adjusted Segment EBITDA, a non-GAAP financial measure, as the total of Adjusted Segment EBITDA for all segments, which excludes unallocated corporate expenses. We use Adjusted Segment EBITDA to internally evaluate the financial performance of our segments because we believe it reflects current core operating performance and provides an indicator of the segment’s ability to generate cash.

The table below presents revenues and Adjusted Segment EBITDA for our reportable segments for the years ended December 31, 2016, 2015 and 2014.

Supplemental Condensed Consolidating Guarantor and Non-Guarantor Financial Information

18. Supplemental Condensed Consolidating Guarantor and Non-Guarantor Financial Information

Substantially all of our domestic subsidiaries are guarantors of borrowings under our Senior Bank Credit Facility and 2022 Notes. The guarantees are full and unconditional and joint and several. All of our guarantors are 100% owned, direct or indirect, subsidiaries.

The following financial information presents condensed consolidating balance sheets, statements of comprehensive income (loss) and statements of cash flows for FTI Consulting, all the guarantor subsidiaries, all the non-guarantor subsidiaries and the eliminations necessary to arrive at the consolidated information for FTI Consulting and its subsidiaries. For purposes of this presentation, we have accounted for our investments in our subsidiaries using the equity method of accounting. The principal eliminating entries eliminate investment in subsidiary and intercompany balances and transactions.
