Description Of Business And Basis Of Presentation	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 and financial services sectors which represent highly complex market and regulatory environments. Our professional service offerings include strategic, financial, operational, technology, risk management, compliance, investigative solutions, dispute resolution services and business process management services. 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 months ended March  31, 2015 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2015.
	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, 2014 included in our Annual Report on Form 10-K filed with the SEC on February 13, 2015 (2014 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.

Acquisitions [Abstract]
Acquisitions	2.ACQUISITIONS
	2015 Acquisitions
	On February 23, 2015, we acquired RevenueMed, Inc. to expand our healthcare business.  RevenueMed specializes in providing coding, revenue cycle management, and business process management services to healthcare providers.  This acquisition included approximately 1,500 professionals primarily located in India and was integrated into the Technology, Data & Process group within our Healthcare segment.  We paid $22.1 million, including selling costs, in cash at closing.  The selling stockholders of RevenueMed can also earn up to an additional $4.0 million based on the business achieving certain performance targets over the period beginning January 1, 2015 and ending June 30, 2015.  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 $3.8 million which was recorded in other current liabilities at net present value using a risk-adjusted discount rate.  As part of our preliminary purchase price allocation, we recorded $7.0 million in identifiable intangible assets, $14.9 million in goodwill, $1.4 million of internally developed software and other net assets of $2.6 million. Net assets includes a liability for uncertain tax positions of $1.3 million and per the terms of the agreement, an offsetting receivable from RevenueMed was recorded. We are still in the process of finalizing our purchase price allocation and the assumptions used to determine the fair value of the intangible assets.  In addition, as we complete our review we may come across additional closing date adjustments not currently recognized in the consolidated financial statements.  These adjustments may revise our preliminary purchase price allocation.  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.
	2014 Acquisitions
	On May 14, 2014, we acquired Cymetrix Corporation to expand our healthcare business.  Cymetrix specializes in providing business process 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. 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 three months ended March 31, 2015, we recorded $15.4 million of other operating benefit reflecting a fair value adjustment (see Note 12 – Fair Value) to reduce the estimated deferred contingent consideration. The opening balance sheet for Cymetrix as of March 31, 2015 was as follows (in thousands):
	Cash	$	1,357
	Accounts receivable, net		11,283
	Other current assets		1,563

	Goodwill		71,264
	Intangible assets		18,000
	Total assets	$	115,291

	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.

Dispositions	3.DISPOSITIONS
	On October 1, 2014, we sold a portion of our Technology, Data & Process business within our Healthcare segment.  We received $1.5 million in cash, net of selling costs, for the sale.  As part of the transaction, we recorded a $0.5 million gain in other operating benefit, which reflected a reduction of $0.8 million in goodwill, $0.1 million in intangible assets, and $0.2 million in other assets.  The Technology, Data & Process business within our Healthcare segment remains a continuing operation and, as such, this transaction did not qualify as discontinued operations.

	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 business process management services which includes 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 and the implications on maximizing the effects of revenue cycle management.
	•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 client-service employees. Long-term compensation expense attributable to client-service employees 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).

	We performed our annual goodwill impairment test as of May 31, 2014. Based on our assumptions, at that time, 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.  As of May 31, 2014, the estimated fair value of our Healthcare, Energy and Financial, Risk & Compliance reporting units exceeded their net asset carrying values by 41%,  41% and 65%, respectively.
	However, the estimated fair value of our Disputes, Investigations & Economics reporting unit was less than the net asset carrying value by approximately 1% as of May 31, 2014.  As such, we performed the second step of the goodwill impairment test on this reporting unit and based on the result in May 2014 a pre-tax goodwill impairment of $122.0 million was recorded as a separate line item within other operating costs (benefit).  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. For further information regarding the impairment, see Note 6 – Goodwill and Intangible Assets, Net in our 2014 10-K.  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 at that time.
	We have reviewed the performance expectations based on 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 since the date of our annual goodwill impairment test or are expected to occur that would trigger a need to perform an interim goodwill impairment test.  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. 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, current and non-current, represent unsecured employee loans. These loans were issued to recruit or retain certain senior-level client-serving employees.  The principal amount and accrued interest on these loans is either paid by the employee 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 used by our clients as part of client engagements. These amounts are amortized into cost of services before reimbursable expenses over their estimated remaining useful life.  During the three months ended March 31, 2015 and 2014, we capitalized or acquired nil and $2.3 million, respectively, in capitalized client-facing software.
	During the three months ended March 31, 2015, we recorded a $6.2 million tenant allowance receivable included in other prepaid expenses and other current assets above, primarily relating to our new office space located in New York.
	Prepaid recruiting and retention incentives, current and non-current, 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 three months ended March 31, 2015 and 2014, we granted $1.6 million and $2.7 million, respectively, of sign-on and retention bonuses, which have been included in current and non-current prepaid recruiting and retention incentives.

Derivatives And Hedging Activity	10.DERIVATIVES AND HEDGING ACTIVITY
	During the three months ended March 31, 2015, the following interest rate derivatives were outstanding (summarized based on month of execution):
		Number of				Total Notional Amount
	Month executed	Contracts	Beginning Date	Maturity Date	Rate	(millions)
	Nov-11	1	31-May-12	31-May-15	0.98%	$10.00

	Mar-15	1	29-May-15	31-May-18	1.47%	$10.00
	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 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 three months ended March 31, 2015. For the three months ended March 31, 2015 and 2014, we recorded $0.1 million in interest expense associated with differentials received or paid under the interest rate derivatives.
	At March 31, 2015, we had $0.4 million of net liability related to the interest rate derivatives.

Bank Debt [Abstract]
Bank Debt	11.BANK DEBT
	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 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 March 31, 2015, we had aggregate borrowings outstanding of $178.7 million, compared to $109.8 million at December 31, 2014.   Based on our financial covenants at March 31, 2015, approximately $208 million in additional borrowings were available to us under the credit facility.  At March 31, 2015, we had $6.4 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 March 31, 2015, the applicable margins on LIBOR and base rate loans were 1.00% and 0.00%, respectively. Depending upon our performance and financial condition, our LIBOR loans will 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 2.4% and 3.1% for the three months ended March 31, 2015 and 2014, 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 March 31, 2015, under the definitions in the credit agreement, our consolidated leverage ratio was 1.3 and our consolidated interest coverage ratio was 5.4.   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 March 31, 2015; however, there can be no assurances that we will remain in compliance in the future.

Fair_Value

Fair Value [Abstract]
Fair Value	12.FAIR VALUE
	Fair value is defined as the price that would be received on the sale of 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 Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by ourselves and our counterparties. However, at March 31, 2015, 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 the 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 three months ended March 31, 2015 and 2014, we recorded $14.9 million and $1.2 million, respectively, in other operating benefit for a net reduction in the liability reflecting changes in the fair value estimate of the contingent consideration for certain acquisitions made in 2014 and 2013 (see Note 2 – Acquisitions).  The following table summarizes the changes in deferred contingent acquisition liabilities (in thousands):
		For the three months ended

	Ending Balance	$	12,929	$	5,156
	At March 31, 2015, 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 March 31, 2015 based upon the short-term nature of the assets and liabilities.
