	1.DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
	Navigant Consulting, Inc. (“we,”  “us,” or “our”) is an independent specialized, global professional services firm that combines deep industry knowledge with technical expertise to enable companies to defend, protect and create value.  We focus on industries and clients facing transformational change and significant regulatory and legal issues. We serve clients primarily in the healthcare, energy, construction and financial services sectors which represent highly complex regulatory environments. Our professional service offerings include strategic, financial, operational, technology, risk management, compliance, investigative solutions, dispute resolution services and revenue cycle management. We provide our services to companies, legal counsel and governmental agencies.  Our business is organized in four reporting segments — Disputes, Investigations & Economics; Financial, Risk & Compliance; Healthcare; and Energy.
	The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim reporting and do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America (GAAP). The information contained herein includes all adjustments, consisting of normal and recurring adjustments except where indicated, which are, in the opinion of management, necessary for a fair presentation of the results of operations for the interim periods presented.
	The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2014.
	These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes as of and for the year ended December 31, 2013 included in our Annual Report on Form 10-K filed with the SEC on February 14, 2014 (2013 10-K).
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and the related notes. Actual results could differ from those estimates and may affect future results of operations and cash flows. We have evaluated events and transactions occurring after the balance sheet date and prior to the date of the filing of this report.

	2.ACQUISITIONS
	2014 Acquisitions
	On May 14, 2014, we acquired Cymetrix Corporation (“Cymetrix”) to expand our healthcare business. Cymetrix specializes in providing revenue cycle management services to hospital and healthcare networks. This acquisition included approximately 600 professionals and was integrated into the Technology, Data & Process group within our Healthcare segment.  We paid $76.9 million, including selling costs, in cash at closing. During the third quarter 2014, we paid approximately $1.4 million for closing date working capital adjustments. The selling stockholders of Cymetrix can also earn up to an additional $25.0 million based on the business achieving certain performance targets over the period beginning November 1, 2014 and ending October 31, 2015. The additional payment is due within 90 days of the end of the performance period.  The deferred contingent consideration is recorded at fair value for each reporting period (see Note 12 – Fair Value).  We estimated the fair value of the deferred contingent consideration on the closing date to be $20.3 million which was recorded in other non-current liabilities at net present value using a risk-adjusted discount rate.  During the nine months ended September 30, 2014, acquisition costs relating to this acquisition totaling $1.2 million were expensed as incurred and included within general and administrative expenses. We have preliminarily estimated the fair value of the assets and liabilities for Cymetrix. We are still in the process of finalizing closing date working capital adjustments and tax related balances. In addition, as we complete our review we may come across additional closing date adjustments not anticipated.  These adjustments may revise our preliminary purchase price allocation.  The excess of the purchase price over the aggregate fair values was recorded as goodwill as required by ASC 805 – Accounting for Business Combinations and Non-controlling Interests.  Post-acquisition adjustments relating to facts and circumstances at the closing date, if any, will be recorded to goodwill when identified for a period not exceeding 12 months.  The preliminary opening balance sheet for Cymetrix is as follows (in thousands):
	Cash	$	1,357
	Accounts receivable, net		11,283
	Other current assets		1,659
	Property and equipment, net		11,824
	Goodwill		71,347
	Intangible assets		18,000
	Total assets	$	115,470
	Total liabilities	$	37,103
	The beginning fair value balance of the Cymetrix intangible assets consisted of the following (amounts in thousands, except year data):
	Category	Useful Life (years)		Amount
	Trade name	4	$	1,900
	Customer lists and relationships	8.3		16,100
			$	18,000
	Also, during 2014, we acquired three small businesses, Leerink Swann Consulting (“Leerink”) in April 2014, HLP Consulting PTE. LTD (“HLP”) in June 2014, and Assay Healthcare Solutions, LLC (“Assay”) in August 2014 for an aggregate purchase price of $11.8 million, of which $9.3 million was paid in cash at closing. Leerink and Assay were integrated into our Healthcare segment, and HLP was integrated into our Disputes, Investigations & Economics segment.
	2013 Acquisitions
	On July 1, 2013, we acquired the assets of The Anson Group, LLC (“Anson”) for an aggregate purchase price of $5.0 million, of which $3.0 million was paid in cash at closing and $2.0 million will be paid in deferred cash payments in three equal installments on each of the first, second and third anniversaries of closing.  During the third quarter of 2014, a payment of $0.7 million was made toward the deferred acquisition liability.  Anson can also earn up to $3.0 million of additional payments based on the business achieving certain performance targets over a three-year period following the closing.  The deferred contingent consideration is recorded at fair value for each reporting period (see Note 12 – Fair Value).  Anson was integrated into our Disputes, Investigations & Economics segment.
	Pro Forma Information
	The following supplemental unaudited pro forma financial information was prepared as if the acquisitions noted above had occurred as of January 1, 2013. The following table was prepared for comparative purposes only and does not purport to be indicative of what would have occurred had the acquisitions been made at that time or of results which may occur in the future (in thousands, except per share data).

Dispositions And Discontinued Operations	'
	3.DISPOSITIONS AND DISCONTINUED OPERATIONS
	On July 8, 2013, we sold the United Kingdom financial services advisory business within our Financial, Risk & Compliance segment.  The transaction included the transition of 45 employees to the purchaser.  As part of the transaction, we received $1.4 million in cash, net of selling costs and a holdback for post-closing working capital adjustments. The sale agreement also allowed for contingent deferred proceeds of $2.5 million payable to us on the 13th month anniversary of the closing based on the achievement of certain performance targets.  The performance targets were not achieved, and there were no contingent deferred proceeds paid to us.  During the three months ended March 31, 2014, we recorded a $0.5 million gain which was included in income from discontinued operations, net of tax, related to the settlement of the holdback mentioned above.
	The operating results of the United Kingdom financial services advisory business have been reported in accordance with ASC Topic 205 as “discontinued operations.”  All other operations are considered “continuing operations.”  Summarized operating results of the discontinued operations are presented in the following table (in thousands):

	On January 31, 2013, we sold a portion of the economics business within our Disputes, Investigations & Economics segment. This disposition facilitated the transition of four experts and certain engagements and approximately 40 other employees to the purchaser.  We received $15.6 million in cash, net of selling costs, for the sale.  As part of the transaction, we recorded a $1.7 million gain in other operating benefit, which reflected a reduction of $7.4 million in goodwill and $6.5 million in working capital.  The economics business remains as a continuing operation and as such did not qualify as discontinued operations.

Segment Information [Abstract]	'
Segment Information	'
	4.SEGMENT INFORMATION
	Our business is assessed and resources are allocated based on the following four reportable segments:
	•The Disputes, Investigations & Economics segment provides accounting, financial and economic analysis, as well as discovery support, data management and analytics, on a wide range of legal and business issues including disputes, investigations and regulatory matters. The clients of this segment are principally companies, along with their in-house counsel and law firms, as well as accounting firms, corporate boards and government agencies.
	•The Financial, Risk & Compliance segment provides strategic, operational, valuation, risk management, investigative and compliance consulting to clients in the highly regulated financial services industry, including major financial and insurance institutions. This segment also provides anti-corruption solutions and anti-money laundering, valuation and restructuring consulting, litigation support and tax compliance services to clients in a broad variety of industries.
	•The Healthcare segment provides strategic, operational, performance improvement and revenue cycle management solutions to clients across the healthcare landscape including health systems, physician practice groups, health insurance providers, government and life sciences companies. We assist clients on issues such as the shift to an outcomes and value-based reimbursements model, ongoing industry consolidation and reorganization, and the required implementation of a new medical coding system.
	•The Energy segment provides management advisory services to utility, government and commercial clients. We focus on creating value for our clients by assisting in their implementation of new business models and creating sustainable excellence on issues ranging from asset investment management, integrated resource planning, renewables, distributed generation, energy efficiency and outage management and restoration.
	The following information includes segment revenues before reimbursements, segment total revenues and segment operating profit. Certain unallocated expense amounts related to specific reporting segments have been excluded from segment operating profit to be consistent with the information used by management to evaluate segment performance. Segment operating profit represents total revenues less costs of services excluding long-term compensation expense attributable to consultants. Long-term compensation expense attributable to consultants includes share-based compensation expense and compensation expense attributed to certain retention incentives (see Note 7  — Share-based Compensation Expense and Note 8 — Supplemental Consolidated Balance Sheet Information).  During the year ended December 31, 2013, we disposed of a portion of our Financial, Risk & Compliance segment and the results of operations from the disposed business have been classified as discontinued operations.  As such, the segment information reflects results of segment operations on a continuing basis (see Note 3 – Dispositions and Discontinued Operations).
	The information presented does not necessarily reflect the results of segment operations that would have occurred had the segments been stand-alone businesses.
	Information on the segment operations has been summarized as follows (in thousands):

	We performed our annual goodwill impairment test as of May 31, 2014.  The test is a two-step test. The first step compares the fair value of a reporting unit to its carrying value. The fair value is determined using a discounted cash flow analysis (income approach) and a comparable company analysis (market approach). The second step is performed only if the carrying value exceeds the fair value determined in step one.
	We determine the fair value of a reporting unit by using an equal weighting of estimated fair value using the income and market approaches. The income approach uses estimated future cash flows and terminal values. Assumptions used to determine future cash flows include: forecasted growth rates; profit margins; longer-term historical performance and cost of capital. Our assumptions are consistent with our internal projections and operating plans. Our internal projections and operating plans and thus our estimated fair value may be impacted by the overall economic environment. Our assumptions may change as a result of, among other things: changes in our estimated business future growth rate; profit margin; long-term outlook; market valuations of comparable companies; the ability to retain key personnel; changes in operating segments; competitive environment and weighted average cost of capital. Under the market approach for determining fair value, we adopt certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk or the risks inherent in the inputs to the valuation. Inputs to the valuation can be readily observable, market-corroborated or unobservable. Wherever possible, we use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs; however, due to the use of our own assumptions about the inputs in measuring fair value, our goodwill impairment testing also makes use of significant unobservable inputs. The fair value of our reporting units is also impacted by our overall market capitalization and may be impacted by volatility in our stock price and assumed control premium, among other things.
	If the carrying value exceeds the fair value determined in step one, step two is performed. Step two requires us to calculate the implied fair value of a reporting unit’s goodwill. This is accomplished by performing a hypothetical purchase price allocation for the reporting unit as of the measurement date, similar to the purchase price allocation used when purchasing a new business. We estimate the fair value of the reporting unit’s assets and liabilities and deem the residual fair value of the reporting unit as the implied fair value of the reporting unit’s goodwill. To the extent that the implied fair value of goodwill is below our carrying value, an impairment is recorded to reduce the carrying value to the implied fair value. The resulting impairment may be significantly higher than the difference between the carrying value and fair value determined in step one as a result of fair value assigned to other assets and liabilities in the hypothetical purchase price allocation completed in step two.
	The key assumptions used in our annual impairment test included:  internal projections completed during our most recent quarterly forecasting process; profit margin improvement generally consistent with our longer-term historical performance; assumptions regarding contingent revenue; revenue growth rates consistent with our longer-term historical performance also considering our near term investment plans and growth objectives; discount rates that were determined based on comparable discount rates for our peer group; company specific risk considerations; and cost of capital based on our historical experience. Each reporting unit’s estimated fair value depends on various factors including its expected ability to achieve profitable growth.
	Based on our assumptions, the estimated fair value exceeded the net asset carrying value for our Healthcare, Energy and Financial, Risk & Compliance reporting units as of May 31, 2014.  Accordingly, there was no indication of impairment of our goodwill for these reporting units.  Healthcare, Energy and Financial, Risk & Compliance reporting units exceeded their net asset carrying values by 41%,  41% and 65%, respectively.
	Based on our impairment test as of May 31, 2014, the estimated fair value of our Disputes, Investigations & Economics reporting unit was less than the net asset carrying value by approximately 1%.    As such, we performed the second step of the goodwill impairment test on this reporting unit.  The second step indicated that the current fair value of the reporting unit’s identifiable intangible assets based upon the hypothetical purchase price allocation mentioned above significantly exceeded the carrying value of those assets.   As such, a pre-tax goodwill impairment of $122.0 million was recorded as a separate line item within other operating costs (benefit) within the unaudited consolidated statements of comprehensive income (loss).  The impairment was non-cash in nature and did not affect our current liquidity, cash flows, borrowing capability or operations; nor did it impact the debt covenants under our credit agreement.  Additionally, we tested the intangible and tangible assets related to this reporting unit based on the related undiscounted future cash flows and concluded that no impairment for these assets existed.
	Historically, our May 31, 2013 and 2012 impairment tests of our Disputes, Investigations & Economics indicated that the reporting unit exceeded its carrying value by 7% and 18%, respectively. Given the relatively lower percentage of excess of carrying value and the decreasing trend in the estimated fair value of this reporting unit, we indicated in previous periodic reports filed with the SEC that if the estimated fair value decreased in future periods, an impairment could result.  Also, due to the relatively low excess carrying value, we have evaluated Disputes, Investigations, & Economics each quarter since our May 31, 2013 impairment test, and at the time, concluded that it was not more likely than not that the fair value of the reporting unit had fallen below the carrying value and as a result the two step impairment test was not performed prior to the May 2014 annual impairment test.
	In completing our annual impairment test at May 31, 2014, we considered historical trends as we updated projections for the business.  While Disputes, Investigations & Economics revenue before reimbursements (RBR) during the three months ended June 30, 2014 was consistent with the corresponding period in 2013 and segment operating profit as a percentage of RBR (margins) were slightly improved, the results were lower than assumed in previous projections.  At the same time, declines in our most recent projections for the year ended December 31, 2014 indicated results were not expected to return to levels included in previous projections.  As a result, as we finalized our longer term growth assumptions for Disputes, Investigations & Economics (as well as our other segments), we reduced our long-term RBR growth rates and also lowered our expectations for margin improvements in the future, partly due to the anticipated change in mix of services within the segment.  We also considered contingent events not included in our projections that would potentially improve RBR and margin performance, and included those factors in our impairment test.  However, the impact of lower long-term RBR and margin growth combined with these other contingent improvement considerations resulted in a lower overall projection from previous projections for the segment.
	We have reviewed the reduced performance expectations of our most recent financial projections and considered the impact of changes to our business and market conditions on our goodwill valuation and determined that no events or conditions have occurred or are expected to occur that would trigger a need to perform an interim goodwill impairment test.  In addition, we performed a sensitivity analysis based on current projections and evaluated various likelihoods of meeting the projections and the potential impact on the fair value.  We will continue to monitor the factors and key assumptions used in determining the fair value of each of our reporting units. There can be no assurance that goodwill or intangible assets will not be further impaired in the future. We will perform our next annual goodwill impairment test on May 31, 2015.
	As we review our portfolio of services in the future, we may exit certain markets or reposition certain service offerings within our business. Consistent with past evaluations, further evaluations may result in redefining our operating segments and may impact a significant portion of one or more of our reporting units. As noted above, if such actions occur, they may be considered triggering events that would result in our performing an interim impairment test of our goodwill and an impairment test of our intangible assets.

	Notes receivable represent unsecured employee loans. These loans were issued to recruit or retain certain senior-level consultants. The principal amount and accrued interest on these loans is either paid by the consultant or forgiven by us over the term of the loans so long as the consultant remains continuously employed by us and complies with certain contractual requirements. The expense associated with the forgiveness of the principal amount of the loans is amortized as compensation expense over the service period, which is consistent with the term of the loans.
	Capitalized client-facing software is marketed or licensed to our clients.  These amounts are amortized into cost of services before reimbursable expenses over their estimated remaining useful life.  During the nine months ended September 30, 2014 and 2013, we capitalized and acquired $2.4 million and $2.5 million, respectively, in client-facing software. In addition, during the nine months ended September 30, 2014, we transferred $3.0 million of developed software into property and equipment, net due to a change in scope for its use.
	Prepaid recruiting and retention incentives include sign-on and retention bonuses that are generally recoverable from an employee if the employee terminates employment prior to fulfilling his or her obligations to us. These amounts are amortized as compensation expense over the period in which they are recoverable from the employee, generally in periods up to six years. During the nine months ended September 30, 2014 and 2013, we granted $11.2 million and $5.9 million, respectively, of sign-on and retention bonuses, which have been included in current and non-current prepaid recruiting and retention incentives.

	The deferred acquisition liabilities at September 30, 2014 consisted of cash obligations related to definitive and contingent purchase price considerations recorded at net present value. During the nine months ended September 30, 2014, we made cash payments of $1.2 million in connection with deferred acquisition liabilities relating to prior period acquisitions and added an additional $1.6 million of deferred acquisition liabilities relating to acquisitions made during the period (see Note 2 – Acquisitions).  Additionally, we reduced the fair value of certain current deferred contingent acquisition liabilities by $0.4 million during the same period (see Note 12 – Fair Value). During the nine months ended September 30, 2014,  $2.6 million relating to accrued incentive compensation liabilities for the 2013 performance year was recorded as additional paid-in capital at the time of grant of certain restricted stock units in 2014.
	The current portion of deferred rent relates to rent allowances and incentives on lease arrangements for our office facilities that expire at various dates through 2025.

	Jul-14	5	11-Jul-14	11-Jul-17	1.10%	$30.00
	We expect the interest rate derivatives to be highly effective against changes in cash flows related to changes in interest rates and have recorded the derivatives as a cash flow hedge. As a result, gains or losses related to fluctuations in the fair value of the interest rate derivatives are recorded as a component of accumulated other comprehensive (loss) income and reclassified into interest expense as the variable interest expense on our bank debt is recorded. There was no ineffectiveness related to the interest rate derivatives during the nine months ended September 30, 2014. During each of the nine months periods ended September 30, 2014 and 2013, we recorded $0.2 million in interest expense associated with differentials received or paid under the interest rate derivatives.

	Our credit agreement provides a $400.0 million revolving credit facility.  At our option, subject to the terms and conditions specified in the credit agreement, we may elect to increase the commitments under the credit facility up to an aggregate amount of $500.0 million.    The credit facility becomes due and payable in full upon maturity in September 2018.  Borrowings and repayments under the credit facility may be made in multiple currencies including U.S. Dollars, Canadian Dollars, United Kingdom Pound Sterling and Euro.
	At September 30, 2014, we had aggregate borrowings outstanding of $158.0 million, compared to $56.7 million at December 31, 2013. Based on our financial covenants at September 30, 2014,  approximately $220 million in additional borrowings were available to us under the credit facility.  At September 30, 2014, we had $8.1 million of unused letters of credit under our credit facility, which have been included as a reduction in the available borrowings above.  The letters of credit are primarily related to the requirements of certain lease agreements for office space.
	At our option, borrowings under the credit facility bear interest at a variable rate equal to an applicable base rate or LIBOR, in each case plus an applicable margin. For LIBOR loans, the applicable margin varies depending upon our consolidated leverage ratio (the ratio of total funded debt to adjusted EBITDA, as defined in the credit agreement). At September 30, 2014, the applicable margins on LIBOR and base rate loans were 1.25% and 0.25%, respectively. Depending upon our performance and financial condition, our LIBOR loans have applicable margins varying between 1.00% and 2.00%,  and our base rate loans have applicable margins varying between zero and 1.00%. Our average borrowing rate (including the impact of our interest rate derivatives; see Note 10 — Derivatives and Hedging Activity) was 2.2% and 2.6% for the three months ended September 30, 2014 and 2013, respectively, and 2.3% and 2.5% for the nine months ended September 30, 2014 and 2013, respectively.
	Our credit agreement contains certain financial covenants, including covenants that require that we maintain a consolidated leverage ratio of not greater than 3.25:1 (except for the first quarter of each calendar year when the covenant requires us to maintain a consolidated leverage ratio of not greater than 3.5:1) and a consolidated interest coverage ratio (the ratio of the sum of adjusted EBITDA (as defined in the credit agreement) and rental expense to the sum of cash interest expense and rental expense) of not less than 2.0:1. At September 30, 2014, under the definitions in the credit agreement, our consolidated leverage ratio was 1.4 and our consolidated interest coverage ratio was 5.2. In addition, the credit agreement contains customary affirmative and negative covenants (subject to customary exceptions), including covenants that limit our ability to incur liens or other encumbrances, make investments, incur indebtedness, enter into mergers, consolidations and asset sales, change the nature of our business and engage in transactions with affiliates, as well as customary provisions with respect to events of default. We were in compliance with the terms of our credit agreement at September 30, 2014; however, there can be no assurances that we will remain in compliance in the future.

Fair Value [Abstract]	'
Fair Value	'
	12.FAIR VALUE
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The inputs used to measure fair value are classified into the following hierarchy:
	Level 1:  Unadjusted quoted prices in active markets for identical assets or liabilities
	Level 2:  Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability
	Level 3:  Unobservable inputs for the asset or liability
	We endeavor to utilize the best available information in measuring fair value.  Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
	Our interest rate derivatives (see Note 10 — Derivatives and Hedging Activity) are valued using counterparty quotations in over-the-counter markets. In addition, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk. The credit valuation adjustments associated with our interest rate derivatives utilize unobservable inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by ourselves and our counterparties. However, at September 30, 2014, we assessed the significance of the impact on the overall valuation and believe that these adjustments are not significant. As such, our interest rate derivatives are classified within Level 2.
	In certain instances our acquisitions provide for deferred contingent acquisition payments.  These deferred payments are recorded at fair value at the time of acquisition and are included in other current and/or non-current liabilities on our consolidated balance sheets. We estimate the fair value of our deferred contingent acquisition liabilities 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 deferred contingent acquisition liabilities are our measures of the future profitability and related cash flows and discount rates. The fair value of our deferred contingent acquisition liabilities is reassessed on a quarterly basis based on assumptions provided to us by segment and business area leaders in conjunction with our business development and finance departments. Any change in the fair value estimate is recorded in the earnings of that period. During the nine months ended September 30, 2014, we recorded $4.4 million in other operating benefit for a reduction in the liability reflecting changes in the fair value estimate of the deferred contingent consideration for certain acquisitions made in 2013 and 2012 (see Note 2 – Acquisitions).  The following table summarizes the changes in the deferred contingent consideration liabilities (in thousands):

	Payments		-107		-3,287
	Ending Balance	$	23,445	$	9,493
	At September 30, 2014, the carrying value of our bank debt approximated fair value as it bears interest at variable rates. We consider the recorded value of our other financial assets and liabilities, which consist primarily of cash and cash equivalents, accounts receivable and accounts payable, to approximate the fair value of the respective assets and liabilities at September 30, 2014 based upon the short-term nature of the assets and liabilities.

	Contingent Acquisition Liability Adjustment
	During the three months ended September 30, 2014 and 2013, we recorded benefits of $0.8 million and $2.0 million, respectively, relating to fair value adjustments to our deferred contingent acquisition liabilities.  Contingent acquisition liabilities are initially estimated based on expected performance at the acquisition date and subsequently reviewed each quarter (see Note 12 – Fair Value).
	During the nine months ended September 30, 2014 and 2013, we recorded benefits of $4.4 million and $2.0 million, respectively, relating to fair value adjustments to our deferred contingent acquisition liabilities.
	Office consolidation
	During the three months ended September 30, 2013, we recorded a benefit of $0.2 million for earlier-than-anticipated sublease income related to one previously vacated office space in 2013.
	During the nine months ended September 30, 2013, in addition to the benefit mentioned above, we recorded $0.5 million of additional depreciation expense relating to the consolidation of two office spaces.
	Gain on disposition of asset
	During the nine months ended September 30, 2013, we recorded a $1.7 million gain relating to the January 31, 2013 sale of a portion of our economics business within our Disputes, Investigations & Economics segment  (see Note 3 – Disposition and Discontinued Operations).
	Goodwill impairment
	During the nine months ended September 30, 2014, we recorded a pre-tax goodwill impairment of $122.0 million (see Note 5 – Goodwill and Intangible Assets, net).
	Other impairment
	During the nine months ended September 30, 2014, we recorded a $0.2 million impairment on software that is no longer being utilized by our consultants for client engagements.

[1]	Stock options with exercise prices greater than the average market price of our common stock during the respective time periods were excluded from the computation of diluted shares because the impact of including the shares subject to these stock options in the diluted share calculation would have been antidilutive. Due to a net loss applicable to common stockholders for the nine months ended September 30, 2014, we excluded 1,256 in potentially dilutive securities from the computation as their effect would have been antidilutive.
