Description of Business and Summary of Significant Accounting Policies

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 leading global business advisory firm dedicated to helping organizations protect and enhance their enterprise value. Our experienced teams of professionals include many individuals who are widely recognized as experts in their respective fields. We believe clients retain us because of our recognized expertise and capabilities in highly specialized areas as well as our reputation for satisfying our clients’ needs. 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 (Loss). 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 stock-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 derive the majority of our revenues from providing professional services to clients in the U.S. For the year ended December 31, 2015, we derived approximately 28% of our 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. We do not have a single customer that represents ten percent or more of our consolidated revenues.

Revenue Recognition

Revenue is 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, revenue is deferred until all criteria for recognizing revenue are met. Provisions are recorded for the estimated realization adjustments on all engagements, including engagements for which fees are subject to review by the 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 revenue 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 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.

In fixed-fee billing arrangements, we agree to a pre-established fee in exchange for a pre-determined 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, revenue is 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.

In performance-based or contingent billing arrangements, fees are tied to 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.

In our Technology segment, unit-based revenues 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. We also generate certain revenue from software licenses and maintenance. 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 revenue upon delivery of the license and recognize the support and maintenance revenue 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 revenue until the earlier of customer acceptance or when the acceptance provisions lapse. Revenues from hosting fees are recognized based on the units used over the term of the hosting agreement. We have certain arrangements with clients in which we provide multiple elements of services under one engagement contract. Revenues under these types of arrangements are accounted for in accordance ASC 605-25, Multiple-Element Arrangements, and recognized pursuant to the criteria described above.

Some clients pay us retainers 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 similar 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. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs.

Share-Based Compensation

We measure share-based compensation using a fair value based recognition method. 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 various judgmental assumptions including volatility and expected term, which are based on our historical experience. We also make assumptions regarding the risk-free interest rate and the expected dividend yield. 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 dividend yield on our common stock is assumed to be zero since we do not pay dividends and have no current plans to do so in the future.

The fair value of restricted stock is measured based on the closing price of the underlying stock on the dates of grant. Awards with performance-based vesting conditions require the achievement of specific financial targets at the end of the specified performance period and the employee’s continued employment. We recognize the estimated fair value of performance-based awards as share-based compensation expense over the performance period. We consider each performance period separately, based upon our determination of whether it is probable that the performance target will be achieved. At each reporting period, we reassess the probability of achieving the performance targets. If a performance target is not met, no compensation cost is ultimately recognized against that target, and, to the extent previously recognized, compensation expense is reversed.

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. Development activities involve a plan or design for the production of new or substantially improved products. When we have determined that technological feasibility for our software products is reached, 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 costs related to software development totaled $19.5 million, $19.3 million, and $15.8 million for the years ended December 31, 2015, 2014 and 2013, respectively. Research and development costs are included in “Selling, general and administrative expenses” on the Consolidated Statements of Comprehensive Income (Loss).

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 $18.2 million for the year ended December 31, 2015, and $20.7 million for each of the years ended December 31, 2014 and 2013, respectively.

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 (Loss).

Income Taxes

Our income tax provision consists principally of 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. The evaluation of the need for a valuation allowance requires management judgment and could impact our financial results and effective tax rate.

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 also 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 disputes that affect our ability to fully collect our billed accounts receivable, potential fee reductions negotiated by clients or imposed by bankruptcy courts as well as the inability of clients to pay our fees. 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 need to record additional allowances or write-offs in future periods. This risk related to a client’s inability to pay may be mitigated to the extent that we receive retainers 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 revenue 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 (Loss), and totaled $15.6 million, $18.3 million, and $13.3 million for the years ended December 31, 2015, 2014 and 2013, 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 over the requisite service period which ranges from a period of one to ten 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 1 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 to 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 revenue 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 $17.6 million and $13.4 million at December 31, 2015 and 2014, respectively. Amortization expense for capitalized software costs were $6.5 million, $6.7 million, and $5.8 million for the years ended December 31, 2015, 2014 and 2013, 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 $44.9 million and $42.0 million for the years ended December 31, 2015 and 2014, 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 November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. The updated standard is effective for the Company at the beginning of its first quarter 2017, with early application permitted as of the beginning of any interim or annual reporting period. The Company elected to early adopt this standard as of December 31, 2015, and retrospectively reclassified $27.3 million of our current deferred tax assets to noncurrent deferred tax liabilities as of December 31, 2014. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issue costs in financial statements. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. In August 2015, FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which states that the SEC would not object to the balance sheet presentation of the costs associated with the line-of-credit arrangement as an asset that would be amortized ratably over the term of the arrangement. The Company elected to early adopt ASU 2015-03 and ASU 2015-15, and has reclassified $5.2 million and $11.6 million of debt issue costs associated with the Company’s long-term debt as of December 31, 2015 and 2014, respectively, from “Other Assets” to “Long-term debt, net” on our Consolidated Balance Sheets. In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This guidance is effective for interim and annual periods beginning after December 15, 2017 and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt this ASU. The Company is evaluating which transition approach to use and the impact of the adoption of this accounting standard update on its consolidated financial statements.

Earnings (Loss) Per Common Share

3. Earnings (Loss) Per Common Share

Basic earnings (loss) per common share are calculated by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings per common share adjust basic earnings per common share for the effects of potentially dilutive common shares. Potentially dilutive common shares include the dilutive effects of shares issuable under our equity compensation plans, including stock options and restricted stock, each using the treasury stock method. Due to a net loss applicable to common stockholders for the year ended December 31, 2013, we excluded 1,232,880 potentially dilutive securities from the computation as their effect would be anti-dilutive.

Special Charges

4. Special Charges

There were no special charges recorded during the year ended December 31, 2015.

During the year ended December 31, 2014, we recorded special charges as a separate line within operating income in our Consolidated Statements of Income (Loss) totaling $16.3 million, of which $0.7 million was non-cash. The charges reflect the contractual post-employment payments and equity award expense acceleration, net of forfeitures of unvested equity and liability awards and annual bonus payments of former executive officers, the termination of the Company’s corporate airplane lease, the closure of the Company’s former West Palm Beach executive office and related lease termination, and updated forecasts of expected sublease income for corporate and segment offices previously vacated.

During the year ended December 31, 2013, we recorded special charges totaling $38.4 million, of which $14.1 million was non-cash. The charges reflect certain executive leadership transition costs and costs related to actions we took to realign our workforce to address current business demands impacting our Corporate Finance & Restructuring and Forensic and Litigation Consulting segments, and to reduce certain corporate overhead within our EMEA region.

The following table details the special charges by segment:

	For the years ended December 31,

Share-Based Incentive Compensation Plans

Under the Company’s 2009 Omnibus Incentive Compensation Plan (Amended and Restated Effective as of June 3, 2015) (“Restated 2009 Plan”), we are authorized to issue up to 7,450,000 shares of common stock, of which no more than 5,400,000 shares of common stock may be issued in the form of restricted or unrestricted shares or other share-based awards. At December 31, 2015, 1,760,495 shares of common stock were available for grant under our Restated 2009 Plan, all of which may be granted as share-based awards.

Our officers, employees, non-employee directors and certain individual service providers are eligible to participate in the Company’s equity compensation plans, subject to the discretion of the administrator of the plans. During the year ended December 31, 2015, we awarded 307,965 restricted shares, stock options exercisable for up to 185,421 shares, 81,016 performance stock units, and 109,665 restricted stock units. These awards are recorded as equity on the Consolidated Balance Sheet. During the year ended December 31, 2015, stock options exercisable for up to 270,506 shares, 113,141 performance stock units and 20,827 restricted shares were forfeited prior to the completion of the vesting requirements.

We have also awarded employees cash-settled stock appreciation rights, cash settled units, and cash-settled performance units. The cash-settled performance units are subject to market conditions based on the adjusted total shareholder return of the Company as compared to the adjusted total shareholder return of the adjusted S&P 500 for the three year period ending March 31, 2017. During the year ended December 31, 2015, we awarded a total of 5,554 cash-settled stock appreciation rights to employees in certain foreign countries. As of December 31, 2015, there were 93,559 cash-settled stock appreciation rights, 17,896 cash-settled units, and 49,472 cash-settled performance units outstanding and there was $1.8 million of unrecognized compensation cost related to these unvested cash-settled awards.

The following table summarizes the option activity under our Equity Compensation Plans as of and for the year ended December 31, 2015. The aggregate intrinsic value in the table below represents the total pre-tax intrinsic value (the difference between the closing price of our common stock on the last trading day of 2015 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, 2015. The aggregate intrinsic value changes based on fluctuations in the fair market value per share of our common stock.

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, long-term receivables and accounts payable, to approximate the fair value of the respective assets and liabilities at December 31, 2015 and 2014, 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”) at December 31, 2015. The fair value of our borrowings on our senior secured bank revolving credit facility (“Senior Bank Credit Facility”) approximates the carrying amount. During the quarter ended September 30, 2015, we repurchased a portion of our 6 ¾% Senior Notes Due 2020 (the “2020 Notes”) through a cash tender offer and satisfied and discharged the entire remaining amount of our 2020 Notes. 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 at December 31, 2015 and 2014:

	December 31,
	2015				2014
	Carrying		Estimated		Carrying		Estimated
	Amount		Fair Value		Amount		Fair Value
Liabilities
Acquisition-related contingent consideration, including current portion ⁽¹⁾	$	4,394	$	4,394	$	6,338	$	6,338
Long-term debt, including current portion		500,000		513,500		711,000		735,000
Total	$	504,394	$	517,894	$	717,338	$	741,338

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

For business combinations consummated on or after January 1, 2009, 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 adjustment is recorded in the earnings of that period and is included within the “Acquisition-related contingent considerations” line in the Consolidated Statements of Comprehensive Income (Loss).

During the years ended December 31, 2015, 2014, and 2013, management determined that the fair value of certain contingent consideration liabilities had declined. This remeasurement of the contingent consideration was based on management’s probability-adjusted present value of the consideration expected to be transferred during the remainder of the earnout period, based on the acquired operations’ forecasted results. The resulting reduction in the liability was recorded as income totaling $1.9 million, $2.7 million and $13.6 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Accretion expense for acquisition-related contingent consideration totaled $0.7 million, $1.0 million and $2.7 million for years ended December 31, 2015, 2014 and 2013, respectively, and is included within “Acquisition-related contingent consideration” in the Consolidated Statements of Comprehensive Income (Loss).

2015 and 2014 Goodwill Impairment Test

For the 2015 and 2014 annual goodwill impairment test performed as of October 1, 2015 and October 1, 2014 respectively, we utilized the quantitative test for our six reporting units using a combination of appropriately weighted income and market approaches. The cash flows employed in the income approach are based on our most recent budgets, forecasts and business plans, as well as various growth rate assumptions for years beyond the current business plan period, discounted using an estimated weighted average costs of capital. The results of the Step 1 goodwill impairment analysis indicated that the estimated fair value of all of our reporting units exceeded their respective carrying values.

2013 Goodwill Impairment Test

In the third quarter of 2013, in addition to reduced levels of M&A activity, our Strategic Communications segment experienced pricing pressure for certain discretionary communications services, including initial public offering support services where there is volume but also increasing competition. These factors compressed segment margins and contributed to a change in the Company’s near-term outlook for this segment. As a result, we performed an interim impairment analysis with respect to the carrying value of goodwill in our Strategic Communications reporting unit in connection with the preparation of our financial statements for the quarter ended September 30, 2013. We concluded that the carrying values of the Strategic Communications reporting unit exceeded its implied fair value, resulting in a $83.8 million goodwill impairment charge.

Other Intangible Assets

Other intangible assets with finite lives are amortized over their estimated useful lives. We recorded amortization expense of $11.7 million, $15.5 million, and $23.0 million during the years ended December 31, 2015, 2014 and 2013, respectively. Based solely on the amortizable intangible assets recorded at December 31, 2015, we estimate amortization expense to be $10.5 million in 2016, $9.7 million in 2017, $8.1 million in 2018, $7.5 million in 2019, $7.3 million in 2020 and an aggregate of $15.2 million in years after 2020. 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.

6% Senior Notes Due 2022. The 2022 Notes have been registered with the SEC. Cash interest is payable semi-annually 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 (as defined below), 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.

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 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 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 has been recorded in “Loss on early extinguishment of debt” within the Consolidated Statements of Comprehensive Income (Loss).

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 so 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 which, 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 not to (i) exceed a maximum consolidated total leverage ratio (the ratio of total funded debt to adjusted EBITDA), and (ii) exceed a maximum consolidated interest coverage ratio (the ratio of adjusted EBITDA minus capital expenditures and cash taxes to cash interest). At December 31, 2015, we were in compliance with all covenants as stipulated in the 2015 Credit Agreement governing our Senior Bank Credit Facility and the indenture governing our 2022 Notes.

There were $200.0 million in borrowings outstanding under the Company’s Senior Bank Credit Facility as of December 31, 2015. The Company has classified these borrowings as long-term debt in the accompanying Consolidated Balance Sheet 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, $1.4 million of the borrowing limit was used (and, therefore, unavailable) as of December 31, 2015 for letters of credit.

There were $5.5 million, $2.8 million and $3.7 million of unamortized debt issue costs related to Senior Bank Credit Facility as of December 31, 2015, 2014 and 2013 respectively. These amounts were included in “Other assets” on our Consolidated Balance Sheets.

Notes payable to shareholders of acquired businesses. In connection with our 2010 acquisition of FS Asia Advisory Limited (formerly Ferrier Hodgson Hong Kong Group), we issued $35.0 million of notes to selling shareholders as part of the total consideration paid. On August 19, 2015, we repaid the remaining $11.0 million balance of notes payable to the former shareholders of FS Asia Advisory Limited.

Guarantees. Currently, we do not have any debt guarantees related to entities outside of the consolidated group. At December 31, 2015, substantially all of our domestic subsidiaries are guarantors of borrowings under our Senior Bank Credit Facility and our Notes in the amount of $500.0 million.

As of December 31, 2015, we have not provided for deferred taxes on $46.8 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 $16.4 million.

At December 31, 2015 and 2014, 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 $13.2 million and $14.4 million were recorded against the Company’s net deferred tax assets at December 31, 2015 and 2014, respectively.

As of December 31, 2015, we have not recorded a $7.6 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 currently under an IRS audit for the year 2012 and are no longer subject to U.S. federal income tax examinations for years prior to 2011. We are also no longer subject to state and local or foreign tax examinations by tax authorities for years prior to 2009. In addition, open tax years related to state and foreign jurisdictions remain subject to examination but are not considered material to our financial position, results of operations or cash flows.

Our liability for uncertain tax positions was $8.1 million and $2.8 million at December 31, 2015 and 2014, respectively. The $5.3 million increase in our liability for uncertain tax positions was due to the timing of tax deductions claimed in prior years. At December 31, 2015, our accrual for the payment of tax- related interest and penalties was not material. Management believes that an adequate provision has been made for any adjustments that may result from tax examinations. Although the timing of the resolution and closure of such examinations is not certain, the Company believes it is reasonably possible that tax audit resolutions could reduce its unrecognized tax benefits by approximately $5.8 million in the next 12 months.

Segment Reporting

17. Segment Reporting

We manage our business in five reportable segments: Corporate Finance & Restructuring (formally known as 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 businesses around the world and provides consulting and advisory services on a wide range of areas, such as restructuring (including bankruptcy), interim management, financings, mergers and acquisitions (“M&A”), M&A integration, valuations and tax issues and as well as financial, operational and performance improvement. Our distressed service offerings generally include corporate restructurings and interim management, and our non-distressed service offerings generally include all other services mentioned above.

Our Forensic and Litigation Consulting segment provides law firms, companies, government clients and other interested parties with dispute advisory, investigations, forensic accounting, business intelligence assessments, data analytics 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 provides e-discovery and information governance, hosting and consulting services and software to its clients. It provides products, services and consulting to companies, law firms, courts and government agencies worldwide. Its comprehensive suite of software and services help clients locate, review and produce ESI, including e-mail, computer files, voicemail, instant messaging, cloud and social media data, as well as financial and transactional data.

Our Strategic Communications segment provides advice and consulting services relating to financial and corporate communications, investor relations, reputation management, brand communications, public affairs, business consulting, digital design and marketing.

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 as the total of Adjusted Segment EBITDA for all segments, which excludes unallocated corporate expenses. Although Adjusted Segment EBITDA is not a measure of financial condition or performance determined in accordance with GAAP, we use Adjusted Segment EBITDA to internally evaluate the financial performance of our segments because we believe it is a useful supplemental measure which 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, 2015, 2014 and 2013.

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.
