The Dispute, Investigative & Regulatory Advisory Services business segment provides consulting
services to a wide range of clients facing the challenges of disputes, litigation, forensic investigations, discovery and regulatory compliance. The clients of the Dispute, Investigative & Regulatory Advisory Services business segment often
include corporate counsels, law firms, corporate boards and special committees. The Business, Financial & Operations Advisory Services business segment provides strategic, operational, financial and technical management consulting services,
as well as claims advisory services, to the management of businesses in a variety of industries, including the healthcare, energy, financial and insurance industries. In accordance with the disclosure requirements of Statement of Financial

(c) Narrative Description of Business

Overview

The Company markets its
services directly to senior and mid-level executives including corporate counsels, law firms, corporate boards, corporate executives and special committees. A variety of business development and marketing channels are used to communicate directly
with current and prospective clients, including on-site presentations, industry seminars, and industry-specific articles. New engagements are sought and won by the Companys senior and mid-level consultants. Future performance will continue to
depend on the consultants ability to win new engagements.

A significant portion of new business arises from prior client
engagements. In addition, the Company seeks to leverage its client relationships in one business segment to cross sell existing services provided by the other segment. Clients frequently expand the scope of engagements during delivery to include
follow-on, complementary activities. In addition, an on-site presence affords the Companys consultants the opportunity to become aware of, and to help define, additional project opportunities as they are identified.

The Company derives its revenues primarily from fees and reimbursable expenses for professional services. A substantial majority of the Companys
revenues are generated under hourly rates billed on a time and expense basis. Clients are typically invoiced on a monthly basis, with revenue recognized as the services are provided. There are also client engagements where the Company is paid a
fixed amount for its services, often referred to as fixed fee billings. This may be one single amount covering the whole engagement or several amounts for various phases or functions. From time to time, the Company earns incremental revenues, in
addition to hourly or fixed fee billings, which are contingent on the attainment of certain contractual milestones or objectives. Such incremental revenues may cause variations in quarterly revenues and operating results if all other revenues and
expenses during the quarters remain the same.

The Companys most significant expense is cost of services before reimbursable
expenses, which generally relates to costs associated with generating revenues, and includes consultant compensation and benefits, sales and marketing expenses, and the direct costs of training and recruiting the consulting staff. Consultant
compensation consists of salaries, incentive compensation and benefits. The Companys most significant overhead expenses are administrative compensation and benefits, and office related expenses. Administrative compensation includes payroll
costs for corporate management and administrative personnel, which are used to indirectly support client projects. Office related expenses primarily consist of rent for the Companys primary office locations.

provides wide and varied service offerings to its broad client base. The Company considers the following to be the Companys key professional services: dispute, investigative, financial, operational and business advisory services, risk
management and regulatory advisory services, and transaction advisory solutions services.

Industry Sectors

The Company provides services to and focuses on industries undergoing substantial regulatory or structural change. The Companys service offerings
are relevant to most industries and the public sector. However, the Company has significant industry-specific knowledge and a large client base in the construction, energy, financial, insurance and healthcare industries. Additionally, the Company
has a strong client presence in the public sector, including federal, state and local governmental agencies. The Company has a long history of work for defendants, insurers and reinsurers in product liability fields.

Human Capital

As of
December 31, 2006, the Company had 2,475 employees, including 1,871 Full Time Equivalent (FTE) consultants. Revenues are primarily generated from services performed by the Companys consultants;

therefore, success depends in large part on attracting, retaining and motivating talented, creative and experienced professionals at all levels. In
connection with recruiting, the Company employs internal recruiters, retains executive search firms, and utilizes personal and business contacts to recruit professionals with significant subject matter expertise and/or consulting experience.
Consultants are drawn from the industries the Company serves, accounting and other consulting organizations, and top rated colleges and universities. The Company seeks to retain its consultants by offering competitive packages of base and incentive
compensation, equity ownership, and benefits.

Independent contractors supplement the Companys consultants on certain engagements.
The Company has found that the practice of retaining independent contractors on a per-engagement basis provides flexibility in adjusting professional personnel levels in response to changes in demand for the Companys professional services.

In addition to the employees and independent contractors discussed above, the Company has acquired and seeks to acquire consulting
businesses to add highly skilled professionals and enhance the services offered by the Company. The Company believes that the strategy of selectively acquiring consulting businesses and consulting capabilities strengthens its platform, market share
and overall operating results.

In connection with recruiting activities and business acquisitions, the Companys policy is to obtain
non-solicitation covenants from senior and some mid-level consultants. Many of these covenants have restrictions that extend 12 months beyond the cessation of employment. The Company utilizes these contractual agreements and other agreements to
reduce the risk of attrition and to safeguard the Companys existing clients, staff and projects.

The Company continually reviews and
adjusts, if needed, the consultants total compensation, which includes salaries, annual cash incentive compensation, and other cash and equity incentives from certain Company programs, to ensure that the consultants compensation is
competitive within the industry, is consistent with the Companys performance and provides the Company the ability to achieve target profitability levels. The Companys compensation structure is reviewed and approved by the Compensation
Committee of the Companys Board of Directors. The Companys bill rates to clients are tiered in accordance with the experience and levels of the consulting staff. The Company monitors and adjusts those bill rates according to the supply
and demand of the then-current market conditions for the services offerings and within the various industries served by the Company.

In
addition, the Companys compensation program requires certain senior consulting leaders to receive payment of a portion of their compensation in restricted stock instead of cash, and the Company has also established equity ownership
requirements for its senior level employees.

Competition

The market for consulting services is intensely competitive, highly fragmented, and subject to rapid change. The market includes a large number of
participants with a variety of skills and industry expertise, including general management and information technology consulting firms, as well as the global accounting firms, and other local, regional, national, and international firms. Many of
these companies are global in scope and have greater personnel, financial, technical, and marketing resources than the Company. The Company believes that its independence, experience, reputation, industry focus, and broad range of professional
services will enable it to compete effectively in the consulting marketplace.

accounted for more than 5 percent of the Companys total revenues for the years ended December 31, 2006 and 2005. The Company had one client from
its Dispute, Investigative & Regulatory Advisory Services segment that accounted for more than 5 percent of the Companys total revenues for the year ended December 31, 2004. The mix of the Companys largest clients may
change from year to year.

International Operations

The Company has offices in Canada, China, and the United Kingdom. In addition, the Company has clients based in the United States of America that have international operations. No country, other than the United States
of America, accounted for more than 10 percent of the Companys total annual revenues in any of the three years ended December 31, 2006. The Companys foreign subsidiaries, in aggregate, represented approximately 9 percent, or $61.8
million, of the Companys total revenues in 2006 compared to less than 5 percent for 2005 and 2004.

|Item 1A. | Risk Factors.
|-------- | -------------

In addition to other information contained in this Annual Report on
Form 10-K and in the documents incorporated by reference herein, the following risk factors should be considered carefully in evaluating the Company and its business. Such factors could have a significant impact on the Companys business,
operating results and financial condition.

The Companys inability to retain and, as necessary, strengthen its executive management team would
be detrimental to the success of our business.

The Company relies heavily on a small group of senior executives and retaining their
services is important to our future success. As the Company continues to expand, the executive management will face increasing



7

##### Table of Contents

challenges and the possible need to supplement or expand the existing team, as well as put in place a necessary succession plan. Any failures in this regard
could impact, among other factors, the Companys revenues, growth and profitability.



The Companys inability to retain highly skilled consulting professionals could have a material adverse effect on the Company.



The Company relies heavily on its consulting staff and management team. The Companys success depends, in large part,
on its ability to hire, retain, develop and motivate highly skilled professionals. Competition for these skilled professionals is intense and the Companys inability to hire, retain and motivate adequate numbers of consultants and managers
could have a serious effect on its ability to meet client needs. A loss of a significant number of its employees could have a serious negative effect on the Company.



The Companys profitability will suffer if it is not able to maintain current pricing and utilization rates.



The Companys revenues, and thereby its profitability, is largely a
function of the bill rates charged to clients and the number of hours the Companys professionals work on client engagements, defined as the utilization of its professionals. Accordingly, if the Company is not able to maintain the
pricing for its services or an appropriate utilization rate for its professionals, revenues, project profit margins and the Companys profitability will suffer. Pricing pressures could result in changes in pricing policies and project profit
margins. Bill rates and utilization rates are affected by a number of factors, including:



| |  |  | Managements ability to predict future demand for services and maintain the appropriate headcount without significant underutilized personnel;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Managements ability to transition employees from completed projects to new engagements;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | The Companys clients perceptions of its ability to add value through its services;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | The pricing of services rendered by the Companys competitors;
| | - |  | --------------------------------------------------------------



| |  |  | The market demand for the services provided by the Company;
| | - |  | -----------------------------------------------------------



| |  |  | The Companys ability to manage attrition rates; and
| | - |  | ----------------------------------------------------



| |  |  | Managements ability to manage significantly larger and more diverse workforces as the Company increases the number of its professionals and executes its
growth strategies.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The Companys use of
equity-based compensation could impact its ability to attract, retain and motivate key employees, if the Companys stock price declines.



Any excessive volatility or decline in the market price of the Companys common stock could impair the Companys ability to use equity-based
compensation to attract, retain and motivate key employees. Compensation and retention related issues represent a continuing challenge for the Company.



The Company faces significant challenges in achieving and managing growth. Failure to meet these management challenges could have a material adverse effect on the
future profitability of the Company.



The increased
scale and complexity of the Companys businesses may require additional management systems that the Company may not be able to implement in a timely manner. The challenges of achieving and managing sustained growth may cause strain on the
Companys management team and the Companys systems. If the Company is unsuccessful in meeting these challenges, this may impair the Companys financial results, competitive position and ability to retain its professionals.



The Company may be exposed to potential risks if the Company is unable
to achieve and maintain effective internal controls.



In the course of managements evaluation of the effectiveness of the Companys internal control over financial reporting as of December 31, 2006, the Company identified one material weakness, as described in



8



---

##### Table of Contents

Item 9A, Controls and Procedures. If the Company fails to achieve and maintain adequate internal controls over financial reporting or fails to implement
necessary new or improved controls that provide reasonable assurance of the reliability of the financial reporting and preparation of our financial statements for external use, the Company may fail to meet its public reporting requirements on a
timely basis, or be unable to adequately report on its business and the results of operations. This could have a material adverse effect on the market price of the Companys stock. Finally, the inherent limitations of internal control over
financial reporting may not prevent or detect all misstatements or fraud, regardless of the adequacy of those controls. Also, projections of any evaluation of effectiveness of controls to future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.



Regulatory and legislative changes affecting the Company, its clients, competitors, or staff could have an impact on the Companys business.



Many of the Companys clients are in highly
regulated industries such as the healthcare, energy, financial institutions and insurance industries. Regulatory and legislative changes in these industries could impact the market for the Companys service offerings and could render its
current service offerings obsolete. In addition, regulatory and legislative changes could impact the competition for consulting services. This change could either increase or decrease the Companys competitive position compared with the
Companys competitors.



The Companys client engagements are
generally short term in nature, less than one year, and may be terminated. The Companys inability to attract business from new or existing clients could have a material adverse effect on the Company.



The Companys inability to continually replace a significant portion of
current engagements with new engagements would have an adverse effect on the Companys ability to meet its current and future commitments.



Many of the client engagement agreements can be terminated by the Companys clients with little or no notice and without penalty. For example, in
engagements related to litigation, if the litigation is settled, our engagement for those services usually is no longer necessary and is promptly terminated. The Company also is retained by clients where the work involves multiple engagements or
stages. In such engagements, there is a risk that a client may choose not to retain the Company for additional stages of an engagement or that a client will cancel or delay additional planned engagements. The Companys engagements are usually
relatively short-term in comparison to its office-related expenses and other infrastructure commitments.



Additionally, the above mentioned factors limit the Companys ability to predict future revenues and required professional staffing. If the Company
inaccurately predicts its future revenues or professional staffing needs, this can impact its financial results.



The Companys client engagements and revenues are frequently event-driven and therefore difficult to forecast.



In the past, the Company has derived significant revenues from events as
inherently unpredictable as the California energy crisis, the Sarbanes-Oxley Act of 2002, and Hurricane Katrina. Such events, in addition to being unpredictable, often have impacts that decline over time as clients adjust to and compensate for such
challenges. These factors limit the Companys ability to predict future revenues and required professional staffing, which can impact its financial results.



The Company has invested in specialized systems, processes and intellectual capital for which the Company may fail to recover its
investment or which may become obsolete.



Specialized
systems and processes have been developed by the Company and provide a competitive advantage in serving current clients and obtaining new clients. Additionally, many of the Companys service offerings rely on technology that is subject to rapid
change. The Companys intellectual capital, in certain service offerings, may be rendered obsolete due to new governmental regulation.

The Companys unsuccessful client engagements could result in damage to its professional reputation or legal
liability which could have a material adverse effect on the Company.

The professional reputation of the Company and its consultants
is critical to the Companys ability to successfully compete for new client engagements and attract or retain professionals. Any factors that damage the Companys professional reputation could have a material adverse effect on the
Companys business.

In addition, the Companys engagements are subject to the risk of legal liability. Any public assertion or
litigation alleging that the Companys services were negligent or that the Company breached any of its obligations to a client could expose the Company to significant legal liabilities, could distract its management and could damage its
reputation. The Company carries professional liability insurance, but such insurance may not cover every type of claim or liability that could potentially arise from the Companys engagements. In addition, the limits of our insurance coverage
may not be adequate to cover a particular claim or a group of claims, and the costs of defense.

Some of the work that the Company does involves
greater risk than ordinary consulting engagements.

The Company does work for clients that for financial, legal or other reasons may
present higher than normal risks. While the Company attempts to identify such higher risk engagements and higher risk clients in time to avoid unnecessary risks or to limit our potential exposure, these efforts may be ineffective and a professional
error or omission in one or more of these higher-risk engagements could have a material adverse impact on our financial condition. Examples of such higher risk engagements include, but are not limited to:



| |  |  | Interim management engagements, usually in hospitals and other healthcare providers;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Expert witness engagements;
| | - |  | ---------------------------



| |  |  | Corporate restructuring engagements, both inside and outside bankruptcy proceedings;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Engagements where the Company delivers a fairness opinion;
| | - |  | ----------------------------------------------------------



| |  |  | Engagements where the Company delivers a compliance effectiveness opinion;
| | - |  | --------------------------------------------------------------------------



| |  |  | Engagements where the Company delivers an actuarial opinion with respect to insurance company loss reserves; and;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Engagements involving independent consultants reports in support of bond financings.
| | - |  | -------------------------------------------------------------------------------------

As the Company becomes larger, the Company increasingly encounters professional conflicts of interest.

As the Company becomes larger, the potential for conflicts of interest also increases. If the Company is unable to accept new engagements for any reason,
including a conflict of interest, our consultants may become underutilized or discontented, which may adversely affect our revenues and results of operations for future periods and may also create challenges for the Company in retaining such
consultants. In addition, although the Company has systems and procedures to identify potential conflicts prior to accepting each new engagement, those systems are not fool-proof and undetected conflicts may result in damage to our reputation and
professional liability.

The Company cannot be assured that it will be able to raise capital or obtain debt financing to consummate future
acquisitions or to meet required working capital needs.

The Company maintains a revolving line of credit agreement to assist in
funding short-term and long-term cash requirements from normal operations. This agreement contains certain covenants requiring, among other things, certain levels of interest and debt coverage. Poor performance of the Company could cause the Company
to be in default of these covenants. In addition, the current agreement may not be sufficient to meet the future needs of the business if a decline in financial performance occurs. There can be no assurance that the Company



10



---

##### Table of Contents

will be able to raise capital or obtain debt financing to effect future acquisitions or to otherwise meet its working capital needs.

Furthermore, if the financial condition of the Companys clients were to deteriorate, resulting in an impairment of their ability to make payments
to the Company, the Company and its financial results would be adversely impacted, which could result in all of the effects described above.

The
Company may not be able to acquire businesses in the future and already acquired business may not achieve expected results.

The
Company has developed its business, in part, through the acquisition of complementary businesses. There has been increasing competition for acquisition targets, as possible acquirers also seek to expand their businesses through acquisitions. The
increased competition may continue to make it more difficult for the Company to complete acquisitions or to complete acquisitions on as favorable terms as in the past. Those factors may also make it more difficult to achieve an acceptable return of
its capital on certain business acquisitions. The financing of acquisitions through cash, borrowings or common stock could also impair liquidity or cause significant stock dilution.

The Company may not be able to effectively integrate the businesses it acquires, which may adversely affect the Company.

The substantial majority of the purchase price the Company pays for acquired businesses is related to intangible assets. The Company may not be able to realize the value of those assets or otherwise realize
anticipated synergies unless it is able to effectively integrate the businesses it acquires. The Company faces multiple challenges in integrating acquired businesses and their personnel, including differences in corporate cultures and management
styles, conflict issues with clients, and the need to divert managerial resources that would otherwise be dedicated to the Companys existing businesses. Any failure to successfully integrate acquired businesses could adversely affect the
financial performance of the Company.

The Companys work with governmental clients has inherent risks related to the governmental contracting
process.

The Company does work for various municipal, state and federal entities and agencies. These projects have risks that
include, but are not limited to, the following:



| |  |  | Government entities reserve the right to audit the Companys contract costs, including allocated indirect costs, and conduct inquiries and investigations of
the Companys business practices with respect to government contracts. If the government finds that the costs are not reimbursable, then the Company will not be allowed to bill for them, or the cost must be refunded to the government if it has
already been paid to the Company. Findings from such an audit also may result in being required to prospectively adjust previously agreed rates for work and affect future margins.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | If a government client discovers improper or illegal activities in the course of audits or investigations, the Company may become subject to various civil and
criminal penalties and administrative sanctions, which may include termination of contracts, forfeiture of profits, suspension of payments, fines and suspensions or debarment from doing business with other agencies of that government. The inherent
limitations of internal controls may not prevent or detect all improper or illegal activities, regardless of the adequacy of such controls.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Government contracts, and the proceedings surrounding them, are often subject to more extensive scrutiny and publicity than other commercial contracts. Negative
publicity related to our government contracts, regardless of its accuracy, may further damage our business by affecting our ability to compete for new contracts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

The impact of any of the occurrences or conditions described above could affect not only the
Companys relationship with the particular government agency involved, but also other agencies of the same or other governmental entities. Depending on the size of the project or the magnitude of the potential costs, penalties or negative
publicity involved, any of these occurrences or conditions could have a material adverse effect on the Companys business or results of operations.

The Company is subject to unpredictable risks of litigation.

Although the Company seeks to avoid litigation whenever
possible, from time to time the Company is party to various lawsuits and claims in the ordinary course of business. Such disputes may arise, for example, from client engagements, employment issues, regulatory actions, corporate acquisitions, real
estate and other business transactions. The costs and outcome of those lawsuits or claims cannot be predicted with certainty, and may be worse than we can foresee. The outcome of such lawsuits and claims could have a material adverse effect on the
Company.

Managements Discussion and Analysis of Financial Condition and Results of Operations relates to the Consolidated Financial Statements included in
this Annual Report on Form 10-K.



Overview



The Company is a specialized independent consulting firm providing dispute,
financial, regulatory and operations advisory services to government agencies, legal counsel and large companies facing the challenges of uncertainty, risk, distress and significant change. The Company focuses on industries undergoing substantial
regulatory or structural change and on the issues driving these transformations.

##### Table of Contents

The Companys revenues, margins and profits are generally not materially impacted by macro economic
business trends, although a long term decline in the U.S. economy would likely impact the Companys business. Examples of impacting events are natural disasters, legislative and regulatory changes, crises in the energy, healthcare, financial
services, insurance and other industries, and significant client specific events.



The Company derives its revenues from fees and reimbursable expenses for professional services. A substantial majority of the Companys revenues are generated under hourly or daily rates billed on a time and
expense basis. Clients are typically invoiced on a monthly basis, with revenue recognized as the services are provided. There are also client engagements where the Company is paid a fixed amount for its services, often referred to as fixed fee
billings. This may be one single amount covering the whole engagement or several amounts for various phases or functions. From time to time, the Company earns incremental revenues, in addition to hourly or fixed fee billings, which are contingent on
the attainment of certain contractual milestones or objectives. Such incremental revenues may cause variations in quarterly revenues and operating results if all other revenues and expenses during the quarters remain the same.



The Companys most significant expense is cost of services before
reimbursable expenses, which generally relates to costs associated with generating revenues, and includes consultant compensation and benefits, sales and marketing expenses, and the direct costs of recruiting and training the consulting staff.
Consultant compensation consists of salaries, incentive compensation and benefits. The Companys most significant overhead expenses are administrative compensation and benefits, and office related expenses. Administrative compensation includes
payroll costs for corporate management and administrative personnel, which are used to indirectly support client projects. Office related expenses primarily consist of rent for the Companys offices.



Critical Accounting Policies



The preparation of the financial statements requires management to make
estimates and assumptions that affect amounts reported therein. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following
critical accounting policies affect its more significant judgments and estimates used in the preparation of its consolidated financial statements:



Revenue Recognition



The Company recognizes revenues as the related professional services are provided. In connection with recording revenues, estimates and assumptions are
required in determining the expected conversion of the revenues to cash. The Company may provide multiple services under the terms of an arrangement. There are also client engagements where the Company is paid a fixed amount for its services. The
recording of these fixed revenue amounts requires the Company to make an estimate of the total amount of work to be performed and revenues are then recognized as efforts are expended based on (i) objectively determinable output measures,
(ii) input measures if output measures are not reliable, or (iii) the straight-line method over the term of the arrangement. From time to time, the Company also earns incremental revenues. These incremental revenue amounts are generally
contingent on a specific event, and the incremental revenues are recognized when the contingencies are resolved.



Accounts Receivable Realization



The Company maintains allowances for doubtful accounts for estimated losses resulting from the Companys review and assessment of its clients
ability to make required payments, and the estimated realization, in cash, by the Company of amounts due from its clients. If the financial condition of the Companys clients were to deteriorate, resulting in an impairment of their ability to
make payments, additional allowances might be required.

Goodwill and Intangible Assets



Intangible assets consist of identifiable intangibles other than goodwill. Identifiable intangible assets other than
goodwill include customer lists and relationships, employee non-compete agreements, employee training methodology and materials, backlog revenue, and trade names. Intangible assets, other than goodwill, are amortized on the straight-line method
based on their estimated useful lives, ranging up to fifteen years.



Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is accounted for by the purchase method of accounting. The Company tests goodwill and
intangible assets annually for impairment. This annual test is performed in the second quarter of each year by comparing the financial statement carrying value of each reporting unit to its fair value. The Company also reviews long-lived assets,
including identifiable intangible assets and goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.



Considerable management judgment is required to estimate future cash flows. Assumptions used in the Companys
impairment evaluations, such as forecasted growth rates and cost of capital, are consistent with internal projections and operating plans. The Company did not recognize any impairment charges for goodwill, indefinite-lived intangible assets or
identifiable intangible assets subject to amortization during the periods presented.



Share-Based PaymentsSFAS No. 123(R)



In December 2004, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 123(R), Share-Based Payment. SFAS No. 123(R) requires that the cost resulting from all share-based
compensation arrangements, such as the Companys stock option and restricted stock plans, be recognized in the financial statements based on their fair value. The provisions of SFAS No. 123(R) were required to be applied effective
January 1, 2006.



SFAS No. 123(R) requires companies
that adopt its provisions prospectively to recognize compensation expense for the unvested portion of previously granted awards and all new awards granted after the adoption date over the respective vesting periods. The Company had outstanding stock
options for approximately 300,000 shares that were unvested as of January 1, 2006. The Company recorded $800,000 in share-based compensation expense related to these unvested options in 2006, and expects to record $700,000 over the remaining
vesting period from 2007 to 2009. The Company assumed an estimated 15 percent forfeiture rate for these stock options. The Company continues to utilize the Black-Scholes-Merton option-pricing model to estimate the fair value of its stock options.



The Company treats its employee stock purchase plan as
compensatory and records the purchase discount from market price of stock purchases by employees as share-based compensation expense.



The adoption of SFAS No. 123(R) does not affect the Companys net cash flows, but it does reduce net earnings and net earnings per share, both
basic and diluted.



Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and EquitySFAS No. 150



The Company is contractually obligated to issue a fixed dollar amount of shares of its common stock. The number of shares to be issued is based on the trading price of the Companys common stock at the time of
issuance. In accordance with SFAS No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity the Company recorded such obligations as current and non-current liabilities in accordance
with the due dates of the obligations. Based on the $19.76 closing price of the Companys common stock at December 31, 2006, 477,000 shares, with a fair value of $9.4 million, would be issued at December 31, 2006 if the settlement of
the obligations was to occur at that date.



Recent Accounting Pronouncements



In June 2006, the FASB issued Interpretation No. 48,
Accounting for Uncertainty in Income Taxesan interpretation of FAS Statement No. 109 (FIN 48). This interpretation clarifies the accounting for uncertainty



19

##### Table of Contents

in income taxes recognized in an entitys financial statements in accordance with SFAS No. 109, Accounting for Income Taxes. It
prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken. This interpretation also provides guidance on derecognition, classification, interest and penalties,
accounting in interim periods, and disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company will be required to adopt this interpretation in the first quarter of 2007. The Company expects the impact on
its consolidated financial statements to be immaterial.



In
September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108 (SAB 108). SAB 108 was issued to provide interpretive guidance on how the effects of the carryover or reversal of prior year
misstatements should be considered in quantifying a current year misstatement. The provisions of SAB 108 are effective for the Company for its December 31, 2006 year-end. The Company adopted SAB 108 during the fourth quarter of 2006 and
accordingly, the Company recorded a $5.8 million, net of tax, cumulative effect of accounting change to accumulated deficit as of January 1, 2006. See Note 7 to the Consolidated Financial Statements.

Results of Operations



Annual Comparisons for the Years ended December 31, 2006, 2005 and 2004



Revenues before Reimbursements. Most revenues before reimbursements are earned from consultants fee revenues
that are primarily a function of billable hours, bill rates and consultant headcount. Revenues before reimbursements were $605.1 million, $508.9 million and $426.9 million for the years ended December 31, 2006, 2005 and 2004, respectively,
which represented increases in revenues before reimbursements of 19 percent for 2006 and 2005, when compared to the preceding year.



Revenues before reimbursements in 2006 and 2005 increased over the prior year due to increases in consulting headcount and improved average rate per hour.
The Company had 1,871 billable full time equivalent (FTE) consultants as of December 31, 2006, compared to 1,705 as of December 31, 2005 and 1,523 as of December 31, 2004. The headcount increases of 10 percent during 2006
and 12 percent during 2005 were due to the Companys business acquisitions and recruiting efforts during those years. The increased staffing levels, along with the commensurate client engagements sought and retained by the Companys
employees, contributed to the increased revenue. Because the Companys bill rates are tiered in accordance with experience and title, an increase in the number of senior level consultants in 2006 improved the Companys average rate per
hour and was a contributing factor in the revenue increase. The consultant utilization rate was generally consistent at 70 percent for the year ended December 31, 2006, compared to 70 percent and 72 percent for each of the years 2005 and 2004,
respectively. The Company calculated its utilization rate measures on a 2,080 hour base for the years.



Segment Total Revenues. Total revenues increased to $681.7 million during 2006 compared to $575.5 million and $482.1 million for the years ended
December 31, 2005 and 2004, respectively, which represented increases in total revenues of 18 and 19 percent each year, respectively, when compared to the preceding year.



Total revenues for the Dispute, Investigative & Regulatory Advisory Services segment increased 26 percent to $318.4
million and 18 percent to $252.3 million for the years ended December 31, 2006 and 2005, respectively, in comparison to the corresponding prior year. The increase in total revenues for 2006 and 2005 compared to the corresponding prior year was
primarily attributable to an increase in headcount, along with the incremental client engagements sought and retained by the Companys employees. The segments increase in headcount was a result of both recruiting efforts and acquisitions
(including Precept, Hutchison and LAC). Total revenues for the Business, Financial & Operations Advisory Services segment increased 12 percent to $363.4 million and 20 percent to $323.2 million for the years ended December 31, 2006 and
2005, respectively, in comparison to the corresponding prior year. The increase in 2006 compared to 2005 was due to the combined effects of headcount and hourly bill rate increases. Incremental revenues which are contingent on the attainment of
certain contractual milestones or objectives were also a contributing factor to the 2006 increase. The increase in 2005 compared to 2004 was primarily attributable to increased headcount, along with the commensurate client engagements required to
support this increased headcount.



Cost of Services before
Reimbursable Expenses. Cost of services before reimbursable expenses increased $49.9 million, or 17 percent, to $349.1 million for the year ended December 31, 2006, and increased $43.5 million, or 17 percent, to $299.2 million for the year
ended December 31, 2005, when compared to the preceding year.



Cost of services before reimbursable expenses increased primarily because of consultant compensation and benefits. The increased employee headcount was the primary cause of the increase in consultant compensation and benefits. As a
percentage of revenues before reimbursements, cost of services before reimbursable expenses decreased to 58 percent for the year ended December 31, 2006 compared to 59 percent and 60 percent for the years ended December 31, 2005 and 2004,
respectively. The decrease in cost of services as a percentage of revenues before reimbursement, which is an indication of increased profitability, primarily related to better utilization of senior professionals with higher chargeability rates and
better assignment of consultants to client engagements in accordance with their skills and chargeability rates.



Cost of services before reimbursable expenses includes amounts related to consultant incentive compensation. Incentive compensation is structured to
reward consultants based on the achieved business

performance objectives approved by the Companys management and the Compensation Committee of the Companys Board of Directors. The amount of
consultant incentive compensation expense during 2006 was generally consistent with 2005. The amount of consultant compensation expense during 2005 was substantially lower when compared to 2004.



General and Administrative Expenses. General and administrative
expenses include facility-related costs, salaries and benefits costs of management and support personnel, bad debt costs for uncollectible billed amounts, professional and administrative services costs, and all other support costs.



General and administrative expenses increased $27.1 million, or 27 percent,
to $127.6 million during the year ended December 31, 2006, and increased $12.9 million, or 15 percent, to $100.5 million in 2005. The increase in expenses was due to several factors including business acquisitions, as well as the support for
additional consulting personnel. Increases in administrative headcount to support the additional consulting personnel contributed to an increase in total administrative payroll and benefit costs. The balance of the increase was attributed to
expansion of existing facilities, facilities acquired through business acquisitions and certain investments made to the Companys infrastructure in the areas of technology, business development and marketing.



General and administrative expenses as a percentage of revenues before
reimbursements were generally consistent at 21 percent, 20 percent, and 21 percent for the years ended December 31, 2006, 2005 and 2004, respectively.



Amortization Expense. Amortization expense includes primarily the amortization of intangible assets such as customer lists and relationships,
and non-compete agreements related to certain business acquisitions.



Amortization expense was $10.0 million and $8.5 million for the years ended December 31, 2006 and 2005, respectively. The increase of $1.5 million in amortization expense for 2006 compared to 2005 represented the amortization of
intangible assets which were acquired as part of the acquisitions made during 2006, partially offset by the lapse of amortization of certain intangible assets acquired in previous years. The amortization expense of the intangible assets related to
the acquisitions consummated during 2006 aggregated $2.7 million, which included $1.2 million of amortization expense for Precept, which was acquired in March 2006. During the year ended December 31, 2005, the increase of $5.0 million in
amortization expense compared to 2004 represented the amortization of intangible assets which were acquired as part of the business acquisitions made during the year. Of the $5.0 million increase, $3.7 million related to amortization of intangible
assets acquired as part of the CBW acquisition, which closed on February 8, 2005.



Litigation. The Company recorded a pre-tax charge of $7.4 million ($4.4 million after tax) during 2006 related to a settlement in its dispute with the City of Vernon, California. The Company originally recorded
a pre-tax litigation charge and related accrued liability of $9.3 million during the third quarter of 2006 and subsequently adjusted the pre-tax charge to reflect the final settlement reached and paid during the fourth quarter of 2006. The Company
recorded litigation charges of $1.3 million for the year ended December 31, 2005, and $0.4 million for year ended December 31, 2004. The matters for which the Company had established the provisions have been resolved and paid.



Interest Expense. Interest expense was $4.9 million and
$4.0 million for the years ended December 31, 2006 and 2005, which represented increases of 24 percent and 60 percent, respectively, when compared to the preceding year. The increases were primarily related to higher weighted-average interest
rates and higher average outstanding borrowings, which included both the line of credit facility and notes payable. The Company utilized its line of credit and other financing arrangements to finance certain transactions, including recently
completed business acquisitions.

Operating results fluctuate from quarter to
quarter as a result of a number of factors, including the significance of client engagements commenced and completed during a quarter, the number of business days in a quarter, employee hiring and utilization rates. The timing of revenues varies
from quarter to quarter due to various factors, such as the ability of clients to terminate engagements without penalty, the attainment of certain contractual objectives, the size and scope of assignments, and general economic conditions. Because a
significant percentage of the Companys expenses are relatively fixed, a variation in the number of client assignments, or the timing of the initiation or the completion of client assignments, can cause significant variations in operating
results from quarter to quarter.



Human Capital Resources



The Company had 1,871 billable FTE consultants as of December 31, 2006,
compared to 1,705 as of December 31, 2005, which represented a net increase of 10 percent, or 166 consultants, for the year.

|Number of administrative and management personnel as of December 31, |  | 502   |   |  | 454   |   |  | 382   |  



The average number of
FTE consultants is adjusted for part-time status and takes into consideration hiring and attrition which occur during the year.



In addition to the headcounts presented above, the Company has hired other employees on a short-term basis or seasonal basis. The Company believes the
practice of hiring these employees provides greater flexibility in adjusting consulting and administrative personnel levels in response to changes in demand for the Companys professional services. The short-term or seasonal hires have been
employed to supplement services on certain engagements or to provide additional administrative support to the consultants.



In connection with certain recruiting activities and business acquisitions, the Companys policy is to obtain non-solicitation covenants from senior
and mid-level consultants. Many of these covenants have restrictions that extend 12 months beyond the cessation of employment. The Company utilizes these contractual agreements and other agreements to reduce the risk of attrition and to safeguard
the Companys existing clients, staff and projects.



The
Company continually reviews and adjusts, if needed, the consultants total compensation, which includes salaries, annual cash incentive compensation, and other cash and equity incentives from certain Company programs, to ensure that the
consultants compensation is competitive within the industry, is consistent with the Companys performance and provides the Company the ability to achieve target profitability levels. The Companys compensation structure is reviewed
and approved by the Compensation Committee of the Companys Board of Directors. The Companys bill rates to clients are tiered in accordance with the experience and levels of the consulting staff. The Company monitors and adjusts those
bill rates according to the supply and demand of the then-current market conditions within the various industry segments served by the Company.



During 2007, in connection with compensation reviews, the Company has been given authority to grant up to $25 million in Key Leader stock
incentives. The restricted stock awards will vest seven years from the grant date, with the opportunity for accelerated vesting over five years based upon the achievement of annual Company-wide performance metrics. The Company intends to issue the
restricted stock at the time of payment of annual performance bonuses in March 2007. In addition, the Company is reviewing other compensatory, developmental and benefits programs to enhance its retention and motivation of consultants.



Liquidity and Capital Resources



Summary



The Company had $11.7 million in cash and cash equivalents at
December 31, 2006, compared to $14.9 million at December 31, 2005. The Companys cash equivalents were primarily limited to commercial paper or securities (rated A or better), with maturity dates of 90 days or less. As of
December 31, 2006, the Company had a $33.6 million balance outstanding under its line of credit agreement compared to $40.8 million as of December 31, 2005.



Working capital, the excess of current assets over current liabilities, was $70.5 million at December 31, 2006,
compared to $41.6 million at December 31, 2005.



The
Company calculates accounts receivable days sales outstanding (DSO) by dividing the accounts receivable balance, net of deferred revenue credits, at the end of the quarter by daily net revenues. Daily net

##### Table of Contents

revenues are calculated by taking quarterly net revenues divided by 90 days, approximately equal to the number of days in a quarter. Calculated as such, DSO
was 78 days at December 31, 2006 compared to 80 days at December 31, 2005.



Cash Flow



For the year
ended December 31, 2006, net cash provided by operating activities was $87.9 million, compared to $58.4 million and $72.2 million for the years ended December 31, 2005 and 2004, respectively. The increase in net cash provided by operating
activities during 2006 compared to 2005 was primarily related to increased net income and a lower investment in working capital. The decrease in net cash provided by operating activities during 2005 compared to 2004 was primarily related to an
increased investment in working capital during 2005.



Net cash
used in investing activities for the year ended December 31, 2006 was $94.4 million, compared to $129.9 million and $81.6 million for 2005 and 2004, respectively. The decrease in net cash used in investing activities for 2006 compared to 2005
was primarily related to a lower amount of investments made in business acquisitions. The increase in net cash used by investing activities for 2005 compared to 2004 was primarily related to an increased investment in business acquisitions. The
Company had capital expenditures of $23.7 million in 2006, which was primarily related to investment in technology purchases, leasehold improvements in certain offices and furniture for its facilities. The Companys capital spending in 2006 was
generally consistent with the $21.3 million spent in 2005. The increase in capital spending during 2005 compared to 2004 primarily related to increased facilities and technology investments.



Net cash provided by financing activities was $3.4 million in 2006, compared
to $49.5 million in 2005 and $7.8 million in 2004. The increased net cash provided by financing activities in 2005 was primarily related to bank borrowings under the line of credit. The Company utilizes its line of credit primarily to finance
certain business acquisitions.



Debt, Commitments and
Capital



As of December 31, 2006, the Company
maintained an unsecured revolving line of credit agreement for $200.0 million, which expires in November 2011. On November 15, 2006, the Company amended its line of credit facility to increase the facility from $175.0 million to $200.0 million,
with the option to increase the facility further to $350.0 million. The amended line of credit allows the Company to borrow in multiple currencies. In addition, the amendment extended the maturity of the agreement from July 2008 to November 2011.



As of December 31, 2006, borrowings under the revolving line
of credit agreement bear interest based, at the Companys option and based on the currency borrowed, on either (1) the higher of the prime rate as defined less 0.15 percent of the determined prime rate or (2) London Interbank Offered
Rate (LIBOR) plus 0.475 percent. The line of credit agreement requires the Company to maintain certain levels of interest and debt coverage. The Company complied with the terms of its line of credit agreement as of December 31, 2006 and
December 31, 2005. As of December 31, 2006, the Company had a $33.6 million balance outstanding under the line of credit agreement compared to $40.8 million as of December 31, 2005.



As of December 31, 2006, the Company had total commitments of $179.4
million, which consisted of $15.3 million in deferred business acquisition obligations, payable in cash and its common stock, notes payable totaling $6.8 million, $33.6 million in line of credit borrowings and $123.8 million in lease commitments.
The lease commitments are related to the Companys leases of office facilities and certain equipment under operating lease arrangements that expire at various dates through 2017.

The Company believes
that its current cash and cash equivalents, future cash flows from operations and the line of credit facility will provide adequate cash to fund anticipated short-term and long-term cash needs from normal operations. In the event the Company was to
make significant cash expenditures in the future for major acquisitions or other non-operating activities, the Company might need additional debt or equity financing, as appropriate.



Off-Balance Sheet Arrangements



The Company does not maintain any off-balance sheet arrangements, transactions, obligations or other relationships with unconsolidated entities that would
be expected to have a material current or future impact on the Companys financial condition or results of operations.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk.
|-------- | -----------------------------------------------------------



The Companys primary exposure to market risks relates to changes in interest rates associated with its borrowings under the line of credit, and its
investment portfolio, classified as cash equivalents. The Companys general investment policy is to limit the risk of principal loss by limiting market and credit risks.



As of December 31, 2006, the Companys investments were primarily limited to A rated securities, with
maturity dates of 90 days or less. These financial instruments are subject to interest rate risk and will decline in value if interest rates rise. Because of the short periods to maturity of these instruments, an increase in interest rates would not
have a material effect on the Companys financial position or operating results.



The Companys market risk associated with its line of credit relates to changes in interest rates. As of December 31, 2006, borrowings under the revolving line of credit agreement bear interest based, at the
Companys option and based on the currency borrowed, on either (1) the higher of the prime rate as defined less 0.15 percent of the determined prime rate or (2) London Interbank Offered Rate (LIBOR) plus 0.475 percent. Based on the
line of credit balance as of December 31, 2006, a substantial rise in interest rates would not have a material effect on the Companys financial position or operating results. The Company does not anticipate any material changes in
interest rates in the short-term future.



Other than the
certain deferred purchase price obligations, notes payable, and borrowings under its revolving line of credit agreement, the Company did not have, at December 31, 2006, any other short-term debt, long-term debt, interest rate derivatives,
forward exchange agreements, firmly committed foreign currency sales transactions, or derivative commodity instruments.



The Company operates in foreign countries, which exposes it to market risk associated with foreign currency exchange rate fluctuations. The Companys
foreign currency exchange rate risk includes operating cash and debt denominated in foreign currency, which is used to fund foreign operations. At December 31, 2006, the Company had $29.6 million of United Kingdom Pounds Sterling borrowings
under the Companys line of credit that was used to fund its operations in the United Kingdom.

|Item 9A. | Controls and Procedures.
|-------- | ------------------------



(1) Evaluation of Disclosure Controls and Procedures



The Company maintains disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) and 15d-15(e)) that are designed to ensure that information required to be disclosed in the Companys reports
filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time frames specified in the SECs rules and forms, and that such information is accumulated and communicated to the Companys management,
including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Any system of controls and procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives.



Management of the Company, with the participation of the principal executive officer and the principal financial officer, evaluated the effectiveness of the design and operation of the Companys disclosure controls and procedures as of
December 31, 2006. Based on the material weakness discussed below, the principal executive officer and principal financial officer have concluded that the Companys disclosure controls and procedures were not effective as of December 31, 2006.



(2) Managements Report on Internal Control over
Financial Reporting



Management of the Company is
responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act). Because of its inherent limitations, internal control over financial reporting may
not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.



Management conducted
an evaluation of the effectiveness of the Companys internal control over financial reporting as of December 31, 2006 based on the framework published by the Committee of Sponsoring Organizations of the Treadway Commission, Internal
ControlIntegrated Framework. In the course of its evaluation, management concluded that the Company did not maintain effective control over financial reporting as of December 31, 2006 due to the existence of a material weakness, described
below. A material weakness represents a significant deficiency (as defined in the Public Company Accounting Oversight Boards Auditing Standard No. 2), or a combination of significant deficiencies, that results in more than a remote likelihood
that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.



Management identified a material weakness in the Companys risk assessment process as of December 31, 2006. Specifically, the Company did not
have effective policies and procedures in place to fully consider the impact of control deficiencies on the Companys prior accounting for relevant non-routine transactions that had a continuing impact on the Companys consolidated
financial statements. As a result, upon the identification of a deficiency in internal control over business combinations during 2006, the Company failed to consider the impact of this deficiency on its accounting for previous business combinations
that were structured in a similar manner. This material weakness resulted in material misstatements in the Companys 2006 preliminary consolidated

financial statements. The aggregate impact of the misstatements has been recorded at January 1, 2006 as a cumulative effect of an accounting change in
connection with the Companys adoption of SEC Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements.



Managements assessment of the effectiveness of the Companys
internal control over financial reporting as of December 31, 2006 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included elsewhere in this Form 10-K.



(3) Changes in Internal Control over Financial Reporting



There has been no change in the Companys internal control over
financial reporting during the Companys fourth quarter that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.



In response to the material weakness noted above, the Company will adopt a
control requiring that, in the event of a significant deficiency relating to a non-routine transaction, the Company will review prior relevant non-routine transactions. The Company also has commenced implementation of additional controls and
procedures to ensure the proper allocation of consideration related to future acquisitions between purchase price and compensation expense. The implementation of these additional controls and procedures is expected to be completed by March 31, 2007.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



The Board of Directors and Stockholders

Navigant Consulting, Inc.:



We have audited managements assessment, presented in Managements Report on Internal Control Over Financial Reporting (Item 9A(2)), that
Navigant Consulting, Inc. (the Company) did not maintain effective internal control over financial reporting as of December 31, 2006, because of the effect of a material weakness identified in managements assessment based on
criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Navigant Consulting, Inc.s management is responsible for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on managements assessment and an opinion on the effectiveness of the
Companys internal control over financial reporting based on our audit.



We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating managements assessment, testing and
evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.



A companys internal control over financial reporting is a process
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being
made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets
that could have a material effect on the financial statements.



Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.



A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material
misstatement of the annual or interim financial statements will not be prevented or detected. Management identified a material weakness in the Companys internal control over financial reporting as of December 31, 2006, related to its risk
assessment process. Specifically, the Company did not have effective policies and procedures in place to fully consider the impact of control deficiencies on the Companys prior accounting for relevant non-routine transactions that had a
continuing impact on the Companys consolidated financial statements. As a result, upon the identification of a deficiency in internal control over business combinations during 2006, the Company failed to consider the impact of this deficiency
on its accounting for previous business combinations that were structured in a similar manner. This material weakness resulted in material misstatements in the Companys 2006 preliminary consolidated financial statements.



In our opinion, managements assessment that Navigant Consulting, Inc.
did not maintain effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the criteria established in Internal Control Integrated Framework issued by the Committee
of Sponsoring

Organizations of the Treadway Commission. Also, in our opinion, because of the effect of the material weakness described above on the achievement of the
objectives of the control criteria, Navigant Consulting, Inc. has not maintained effective internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal Control Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission.



We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Navigant Consulting, Inc. and subsidiaries as of
December 31, 2006 and 2005, and the related consolidated statements of income, stockholders equity, and cash flows for each of the years in the three-year period ended December 31, 2006, and our report dated March 1, 2007
expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



The Board of Directors and Stockholders

Navigant Consulting, Inc.:



We have audited the accompanying consolidated balance sheets of Navigant Consulting, Inc. and subsidiaries (the
Company) as of December 31, 2006 and 2005, and the related consolidated statements of income, stockholders equity and cash flows for each of the years in the three-year period ended December 31, 2006. In connection with
our audits of the consolidated financial statements, we also have audited the financial statement schedule as listed in the accompanying index. These consolidated financial statements and financial statement schedule are the responsibility of the
Companys management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedule based on our audits.



We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.



In our opinion,
the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Navigant Consulting, Inc. and subsidiaries as of December 31, 2006 and 2005, and the results of their operations and
their cash flows for each of the years in the three-year period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.



As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for stock-based compensation effective
January 1, 2006.



As discussed in Note 7 to the consolidated
financial statements, the Company changed its method for quantifying errors in 2006.



We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Companys internal control over financial reporting as of
December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 1, 2007 expressed an
unqualified opinion on managements assessment of, and an adverse opinion on the effective operation of, internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.    
DESCRIPTION OF BUSINESS



Navigant Consulting, Inc. (the Company) is a specialized independent consulting firm providing dispute, financial, regulatory and operations advisory services to government agencies, legal counsel and large companies facing the
challenges of uncertainty, risk, distress and significant change. The Company focuses on industries undergoing substantial regulatory or structural change and on the issues driving these transformations.



The Company is headquartered in Chicago, Illinois and has offices in various
cities within the United States, as well as offices in Canada, China, and the United Kingdom. The Companys foreign subsidiaries, in aggregate, represented approximately 9 percent of the Companys total revenues in 2006 and less than 5
percent of the Companys total revenues for 2005 and 2004.



2.    
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



Principles of Consolidation



The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany transactions have been eliminated in consolidation.



Use of Estimates



The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the consolidated financial statements and the related notes. Actual results could differ from those estimates and may affect future results of operations and cash flows.



Reclassifications



Certain amounts in prior years consolidated financial statements have
been reclassified to conform to the current years presentation.



Cash and Cash Equivalents



Cash equivalents
are comprised of liquid instruments with original maturity dates of 90 days or less.



Fair Value of Financial Instruments



The Company considers the recorded value of its financial assets and liabilities, which consist primarily of cash and cash equivalents, accounts receivable, bank borrowings, and accounts payable, to approximate the
fair value of the respective assets and liabilities at December 31, 2006 and 2005 based upon the short-term nature of the assets and liabilities.



Accounts Receivable Realization



The Company maintains allowances for doubtful accounts for estimated losses resulting from the Companys review and assessment of its clients
ability to make required payments, and the estimated realization, in cash, by the Company of amounts due from its clients. If the financial condition of the Companys clients were to deteriorate, resulting in an impairment of their ability to
make payment, additional allowances might be required.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)



Property and Equipment



Property and equipment are recorded at cost. Depreciation is computed using the straight-line method based on the estimated
useful lives of three to seven years for furniture, fixtures and equipment, three years for software, and forty years for buildings. Amortization of leasehold improvements is computed over the shorter of the remaining lease term or the estimated
useful life of the asset.



Operating Leases



The Company leases office space under operating leases. Some of the lease
agreements contain one or more of the following provisions or clauses: tenant allowances, rent holidays, lease premiums, and rent escalation clauses. For the purpose of recognizing these provisions on a straight-line basis over the terms of the
leases, the Company uses the date of initial possession to begin amortization, which is generally when the Company enters the space and begins to make improvements in preparation of intended use.



For tenant allowances and rent holidays, the Company records a deferred rent
liability on the consolidated balance sheets and amortizes the deferred rent over the terms of the leases as reductions to rent expense on the consolidated statements of income. For scheduled rent escalation clauses during the lease term or for
rental payments commencing at a date other than the date of initial occupancy, the Company records minimum rental expenses on a straight-line basis over the terms of the leases in the consolidated statements of income.



Goodwill and Intangible Assets



Intangible assets consist of identifiable intangibles other than goodwill.
Identifiable intangible assets other than goodwill include customer lists and relationships, employee non-compete agreements, employee training methodology and materials, backlog revenue, and trade names. Intangible assets, other than goodwill, are
amortized on the straight-line method based on their estimated useful lives, ranging up to fifteen years.



Goodwill represents the difference between the purchase price of acquired companies and the related fair value of the net assets acquired, which is
accounted for by the purchase method of accounting. The Company tests goodwill and intangible assets annually for impairment. This annual test is performed in the second quarter of each year by comparing the financial statement carrying value of
each reporting unit to its fair value. The Company also reviews long-lived assets, including identifiable intangible assets and goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may
not be recoverable.



Considerable management judgment is
required to estimate future cash flows. Assumptions used in the Companys impairment evaluations, such as forecasted growth rates and cost of capital, are consistent with internal projections and operating plans. The Company did not recognize
any impairment charges for goodwill, indefinite-lived intangible assets or identifiable intangible assets subject to amortization during the periods presented.



Revenue Recognition



The Company recognizes revenues as the related professional services are provided. In connection with recording revenues, estimates and assumptions are
required in determining the expected conversion of the revenues to cash. The Company may provide multiple services under the terms of an arrangement. There are also client engagements where the Company is paid a fixed amount for its services. The
recording of these fixed revenue amounts requires the Company to make an estimate of the total amount of work to be performed and



F-8

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)



revenues are then recognized as efforts are expended based on (i) objectively determinable output measures, (ii) input measures if output measures
are not reliable, or (iii) the straight-line method over the term of the arrangement. From time to time, the Company also earns incremental revenues. These incremental revenue amounts are generally contingent on a specific event, and the
incremental revenues are recognized when the contingencies are resolved.



Legal



The Company
records legal expenses as incurred. Potential exposures related to unfavorable outcomes of legal matters are accrued for when they become probable and reasonably estimable under SFAS No. 5.



Share-Based PaymentsSFAS No. 123(R)



Effective January 1, 2006, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 123(R), Share-Based Payment, which replaces SFAS No. 123, Accounting for Stock-based Compensation, and supersedes APB Opinion No. 25, Accounting for Stock Issued to
Employees. SFAS No. 123(R) requires that the cost resulting from all share-based compensation arrangements, such as the Companys stock option and restricted stock plans, be recognized in the financial statements based on their grant
date fair value. The Company adopted SFAS 123(R) using the modified prospective application method. Under the modified prospective application method, prior periods are not revised for comparative purposes. The valuation provisions of SFAS 123(R)
apply to new awards and to unvested awards that are outstanding on the effective date (January 1, 2006) or subsequently modified or cancelled.



Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and EquitySFAS No. 150



The Company is contractually obligated to issue a fixed dollar amount of
shares of its common stock. The number of shares to be issued is based on the trading price of the Companys common stock at the time of issuance. In accordance with SFAS No. 150, Accounting for Certain Financial Instruments with
Characteristics of Both Liabilities and Equity the Company recorded such obligations as current and non-current liabilities based on the due dates of the obligations. Using the $19.76 closing price of the Companys common stock at
December 31, 2006, 477,000 shares would be issued if the settlement of the obligations was to occur at the current balance sheet date, with a fair value of $9.4 million.



Income Taxes



Income taxes are accounted for in accordance with the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply
to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment
date.



Treasury Stock



Treasury stock transactions are recorded at cost.



Foreign Currency Translation



The balance sheets of the Companys foreign subsidiaries are translated
into U.S. dollars using the period-end exchange rates, and revenues and expenses are translated using the average exchange rates for each

period. The resulting translation gains or losses are recorded in stockholders equity as a component of accumulated other comprehensive income (loss).
Gains and losses resulting from foreign exchange transactions are recorded in consolidated statements of income. Such amounts were not significant during the periods presented.



Comprehensive Income



Comprehensive income consists of net income and foreign currency translation adjustments. It is presented in the consolidated statements of
stockholders equity.

6.    
NET INCOME PER SHARE (EPS)



Basic earnings per share (EPS) is computed by dividing net income by the number of basic shares. Basic shares are the total of the common shares outstanding and the equivalent shares from obligations presumed payable in common stock, both
weighted for the average number of days outstanding for the period. Basic shares exclude the dilutive effect of common shares that could potentially be issued due to the exercise of stock options, vesting of restricted shares, or satisfaction of
necessary conditions for contingently issuable shares. Diluted EPS is computed by dividing income by the diluted shares, which are the total of the basic shares outstanding and all potentially issuable shares, based on the weighted average days
outstanding for the period.



For the years ended
December 31, 2006, 2005 and 2004, the components of basic and diluted shares (shown in thousands and based on the weighted average days outstanding for the periods) are as follows:

For the years ended
December 31, 2006, 2005 and 2004, the Company had stock options of 0.3 million, 0.3 million, and 0.2 million, respectively, which were excluded from the computation of diluted shares. The shares were excluded from the diluted
share computation because these shares had exercise prices greater than the average market price and the impact of including these options in the diluted share calculation would have been antidilutive.



In connection with certain business acquisitions, the Company is obligated to
issue a certain number of shares of its common stock. Obligations to issue a fixed number of shares are included in the basic earnings per share calculation. Obligations to issue a fixed dollar amount of shares where the number of shares is based on
the trading price of the Companys shares at the time of issuance are included in the diluted earnings per share calculation.



In accordance with SFAS No. 128, Earnings per Share, the Company uses the treasury stock method to calculate the dilutive effect of its
common stock equivalents should they vest. The exercise of stock options or vesting of restricted shares and restricted stock unit shares triggers excess tax benefits or tax deficiencies that reduce or increase the dilutive effect of such shares
being issued. The excess tax benefits or deficiencies are based on the difference between the market price of the Companys common stock on the date the equity award is exercised or vested and the cumulative compensation cost of the stock
options, restricted shares and restricted stock units.



7.    
STOCKHOLDERS EQUITY



In
September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108 (SAB 108). SAB 108 was issued to provide interpretive guidance on how the effects of the carryover or



F-16

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)



reversal of prior year misstatements should be considered in quantifying a current year misstatement. The provisions of SAB 108 are effective for the Company
for its December 31, 2006 year-end. The Company adopted SAB 108 during the fourth quarter of 2006 and accordingly, the Company recorded a $5.8 million, net of tax, cumulative effect of accounting change to accumulated deficit as of
January 1, 2006. The $5.8 million cumulative effect of accounting change related to certain payments in connection with previously disclosed acquisitions and revenue recognition related to a long-term claims processing engagement. The
cumulative effect of accounting change related to payments in connection with previously disclosed acquisitions aggregated $4.4 million. The Company has determined that such payments previously determined to be purchase price were compensatory in
nature. The net income impact of the additional compensation expense would have been $0.2 million in 2002, $1.3 million in 2003, $1.5 million in 2004, and $1.4 million in 2005. The cumulative effect of the accounting change related to the revenue
recognition of a long-term claims processing engagement was $1.4 million. If revenue had been recorded correctly, net income would have been reduced by $0.8 million in 2004 and $0.6 million in 2005. The error related to an inadvertent acceleration
of revenue based on billing terms.



The Company did not have
any preferred stock transactions during the year ended December 31, 2006.



In connection with the Precept acquisition, the Company issued 636,000 shares of its common stock valued at $12.0 million at the time of closing. As part of the purchase price of other acquisitions made during 2006,
the Company issued 177,000 shares of its common stock.



In
January 2006, in connection with the acquisition of Tucker Alan, Inc. (Tucker), which occurred on January 30, 2004, the Company issued 340,000 shares of its common stock, the last of three annual installments of the purchase price.
During the year ended December 31, 2006, the Company issued 333,000 shares of its common stock in connection with deferred purchase price obligations of other acquisitions made during previous years.



During the first quarter of 2006, the Company issued 265,000 shares of
restricted stock to employees to satisfy a portion of their 2005 annual incentive bonus. The shares of restricted stock vested during the third quarter of 2006.



The Company had a net excess tax benefits of $4.3 million on stock options exercised and restricted stock awards vested during the year ended
December 31, 2006.



Stock Appreciation Rights



During 2000, the Company granted 200,000 shares of stock
appreciation rights. During 2004, two-thirds of the 200,000 shares were exercised and $2.4 million in cash was paid for the accumulated appreciation in stock value since grant date. During 2005, the remaining one-third of the 200,000 shares was
exercised and $1.4 million was paid for the accumulated appreciation in stock value since grant date. As of December 31, 2006, there were no stock appreciation rights outstanding.



Stockholder Rights Plan



On December 15, 1999, the Companys Board of Directors adopted a Stockholders Rights Plan (the Rights Plan) and declared a dividend
distribution of one Right (a Right) for each outstanding share of common stock, to stockholders of record at the close of business on December 27, 1999. The description and terms of the Rights are set forth in a Rights Agreement
(the Rights Agreement) between the Company and LaSalle Bank, as successor Rights Agent. Each Right will entitle its holder, under certain circumstances described in the Rights

Agreement, to purchase from the Company one one-thousandth of a share of its Series A Junior Participating Preferred Stock, $.001 par value at an exercise
price of $75 per Right, subject to adjustment. The Rights are not exercisable until the Distribution Date (as defined in the Rights Agreement) and will expire at the close of business on December 15, 2009, unless earlier redeemed or exchanged
by the Company.



8.    
SHARE-BASED COMPENSATION EXPENSE



Summary



On June 30, 1996, the Company
adopted a Long-Term Incentive Plan (the 1996 LTIP) that provides for common stock, common stock-based and other performance incentives to employees, consultants, directors, advisors and independent contractors of the Company. On
May 4, 2005, the Companys shareholders approved, at the 2005 Annual Meeting of Shareholders, the 2005 Long-Term Incentive Plan (2005 LTIP and, together with the 1996 LTIP, the LTIP). The 2005 LTIP provided for an
additional 5.25 million shares of the Companys common stock available to be issued under the plan. In November 2001, the Company adopted a Supplemental Equity Incentive Plan (SEIP) to retain and recruit certain middle and
senior-level employees and to optimize shareholder value. The SEIP only provides for the grant of nonqualified stock options. The SEIP did not require shareholder approval; therefore, it was not voted on or approved by the Companys
stockholders.



The purposes of the plans are to (1) align
the interests of the Companys shareholders and recipients of awards under the plan, (2) attract and retain officers, other employees, non-employee directors, consultants, independent contractors and agents, and (3) motivate such
persons to act in the long-term best interests of the Companys shareholders. The incentives offered by the Company under the plans are an important component of the compensation for the recipients.



Share-based Compensation Plans



The share-based compensation plans use restricted stock, stock options, and
an employee stock purchase plan to provide incentives to the Companys employees.



Restricted Stock Outstanding



As of December 31, 2006, the Company had 2.0 million restricted stock and equivalent units outstanding at a weighted average measurement price of $19.07 per share. The measurement price is the market price of the Companys
common stock at the date of grant of the restricted stock and equivalent units. The restricted stock and equivalent units were granted out of the LTIP. The majority of the awards outstanding at December 31, 2006 vest over four years in 25
percent annual installments from the grant date.

During the years ended December 31, 2006, 2005 and 2004, the Company received $9.1 million, $8.7
million and $7.8 million of cash from employee stock option exercises and employee stock purchases. Additionally, during the years ended December 31, 2006, 2005 and 2004, the Company generated excess tax benefits of $4.7 million, $5.9 million
and $13.1 million, respectively, related to these transactions.



Employee Stock Purchase Plan



During 1996, the
Company implemented a plan (the 1996 ESPP) that permits employees to purchase shares of the Companys common stock each quarter at 85 percent of the market value. The market value of shares purchased for this purpose is determined
to be the closing market price on the last day of each calendar quarter. During the years ended December 31, 2006, 2005, and 2004, the Company issued 287,000, 291,000 and 107,000 shares, respectively, of its common stock related to employee
stock purchases under the 1996 ESPP.



On May 3, 2006, at
the Companys Annual Meeting of Stockholders, the Companys stockholders approved a new employee stock purchase plan (the ESPP) that will become effective on January 1, 2007. The new ESPP will expire on the date that all
of the shares available under the new ESPP are issued to employees. The maximum number of shares of the Companys common stock that can be issued under the ESPP is 2.5 million shares, subject to certain adjustments.



For the Year Ended December 31, 2006



In accordance with SFAS No. 123(R), the Company recognizes compensation
expense for the unvested portion of previously granted awards and all new awards granted after the adoption date over the respective vesting periods. The Company had 300,000 stock options that were unvested as of January 1, 2006. The remaining
2.1 million stock options outstanding at January 1, 2006 were fully vested. The Company used the Black-Scholes-Merton option-pricing model to estimate the fair value of the unvested stock options. The Company assumed an estimated 15
percent forfeiture rate for these stock options. The Company recorded $800,000 in share-based compensation expense related to these unvested options during 2006, and expects to record $700,000 over the remaining vesting period from 2007 to 2009.



The Company granted 82,000 stock options during the first
quarter of 2006 and there were no other options grants during the remainder of the year. The Company recorded $280,000 during the year ended December 31, 2006 related to the fair value of these options and expects to record $580,000 over the
remaining term. For purposes of calculating compensation cost under SFAS No. 123(R), the fair value of each option grant is estimated as of the date of grant using the Black-Scholes-Merton option-pricing model. The Company used its historical
stock price volatility for purposes of estimating the stock options fair value. The weighted average fair value of options granted and the assumptions used in the Black-Scholes-Merton option pricing model were as follows:



|                                         |  |      |       |  
|---------------------------------------- |  | ---- | ----- | -
|                                         |  | 2006 |      
|Fair value of options granted            |  | $    | 10.52 |  
|Expected volatility                      |  |      | 64.0  | %
|Risk free interest rate                  |  |      | 4.3   | %
|Forfeiture rate                          |  |      | 0.0   | %
|Dividend yield                           |  |      | 0.0   | %
|Contractual or expected lives (in years) |  |      | 4.2   |  



The Company estimated
a zero forfeiture rate for these stock option grants as the awards have short vesting terms or have a low probability of forfeiture.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)



Share-based compensation expense is recorded for restricted stock awards on a straight-line basis
over the vesting term based on the fair value at grant date. The agreements for certain restricted stock awards outstanding at December 31, 2006 contain provisions that allow for an acceleration of vesting if the Company achieves a certain
level of financial performance. Accordingly, the Company may accelerate the unamortized compensation expense related to those awards and, therefore, the Company may experience variations in share-based compensation expense from period to period.



In addition, share-based compensation expense is recorded for
certain stock options and stock appreciation rights (variable accounting awards) that have been awarded to the Companys employees and are subject to variable accounting treatment. As of December 31, 2006, the Company had less
than 25,000 shares that were subject to variable accounting treatment. Compensation expense (or credit) for these variable accounting awards is recorded, on a cumulative basis, for the increase (or decrease) in the Companys stock price above
the grant date fair value.



The Company treats its ESPP as
compensatory under SFAS No. 123(R) and records the purchase discount from market price of stock purchases by employees as share-based compensation expense. Previously, the Company followed Accounting Principles Board (APB) Opinion
25, Accounting for Stock Issued to Employees as it related to employee stock purchase plans and did not record an expense for any discounts.



Upon adoption of SFAS No. 123(R), an entity that had a policy of recognizing the effect of forfeitures only as they occurred, as the Company did, is
required to estimate the number of instruments outstanding for which the requisite service is not expected to be rendered. SFAS No. 123(R) requires a cumulative effect of a change in accounting principle to be recognized for the difference
between compensation costs recognized to date using actual forfeitures and the costs that would have been recognized to date using estimated forfeitures. The Company did not record a cumulative effect of a change in accounting principle due to the
impact being insignificant.



SFAS No. 123(R) amended FASB
Statement No. 95, Statement of Cash Flows, to specify the classification in cash flow statements of the tax benefits realized from share-based payment arrangements. SFAS No. 123(R) requires that the amount of the tax benefits
reported as an addition to, or deduction from, additional paid-in capital be reported as a financing activity rather than an operating activity. In accordance with SFAS No. 123(R), the Company now classifies the excess tax benefits from
issuances of common stock as a financing activity.



The
adoption of SFAS No. 123(R) does not affect the Companys net cash flows, but it does reduce net earnings and net earnings per share, both basic and diluted.



For the Years Ended December 31, 2005 and 2004



Prior to the adoption of SFAS No. 123(R), the Company accounted for share-based compensation using the intrinsic
value-based method, as prescribed under APB Opinion No. 25 and related interpretations, for its share-based compensation plans for option and restricted stock awards. Accordingly, prior to the adoption of SFAS No. 123(R), no share-based
compensation costs had been recognized for those option grants where the exercise price was equal to the fair market value of the underlying common stock on the date of grant.

During 2006, the
Company recorded a valuation allowance of approximately $500,000 related to certain capital loss carry forwards that expired as of December 31, 2006. Additionally during 2006, the Company recorded a valuation allowance of approximately $300,000
related to certain foreign operating loss carry forwards. The Company has not recorded a valuation allowance against any of its other deferred tax assets, as it believes it is more likely than not that such deferred tax assets are recoverable from
future results of operations.



The Company continues to
reinvest any undistributed earnings of foreign subsidiaries in developing its business in those countries in which the earnings were generated. There were no unremitted earnings in 2006.



In June 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxesan
interpretation of FAS Statement No. 109 (FIN 48). This interpretation clarifies the accounting for uncertainty in income taxes recognized in an entitys financial statements in accordance with SFAS No. 109,
Accounting for Income Taxes. It prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken. This interpretation also provides guidance on derecognition,
classification, interest and penalties, accounting in interim periods, and disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company will be required to adopt this interpretation in the first quarter of
2007. The Company expects the impact on its consolidated financial statements to be immaterial.

at any time. The Companys contributions to the various plans were $5.0 million, $5.1 million and $4.0 million in the years ended December 31, 2006, 2005 and 2004, respectively.



The Company has other retirement plans for its foreign subsidiaries participants. During the year ended
December 31, 2006, the Company paid $1.3 million for retirement savings related plans.



15.    
RELATED PARTY TRANSACTIONS



Governor Thompson, one of the Companys Directors, was Chairman of the law firm of Winston & Strawn through August 2006. He is currently Senior Chairman at Winston & Strawn. Winston & Strawn has provided
legal representation for the Company in the past and may provide services to the Company in the future. Total payments related to services rendered were less than $0.1 million in 2006 and 2005, and were $0.3 million for 2004.



The Company leases office space from Equity Office Properties
(EOP). William M. Goodyear was a Trustee on the Board of Trustees at EOP. Mr. Goodyear resigned as a Trustee of EOP during February 2007. During the years ended December 31, 2006, 2005 and 2004, the Company paid $2.5 million,
$3.4 million, and $2.5 million, respectively, to EOP in connection with such space. These leases were executed at market terms.



16.    
LITIGATION AND SETTLEMENTS



On
November 28, 2006, the Company reached an agreement with the City of Vernon, California to settle for $7.4 million all claims related to an arbitrators interim award against the Company in an arbitration proceeding relating to a dispute
with the City. The dispute related to certain electric distribution maintenance services that the Company provided to the City prior to November 30, 2003. Since then, the Company no longer provides electric distribution maintenance services.
During 2006, the Company paid the $7.4 million settlement and recorded such payment as a litigation charge.



From time to time, the Company is party to various other lawsuits and claims in the ordinary course of business. While the outcome of those lawsuits or
claims cannot be predicted with certainty, except as otherwise described above, the Company does not believe that any of those additional lawsuits or claims will have a material adverse effect on the financial condition and results of operation of
the Company.
