We are a leading global consulting firm specializing in providing economic, financial and management consulting services. We advise clients on economic and financial matters pertaining to litigation and regulatory proceedings, and guide corporations through critical business strategy and performance-related issues. Since 1965, we have been engaged by clients for our unique combination of functional expertise and industry knowledge, and for our objective solutions to complex problems. We combine economic and financial analysis with expertise in litigation and regulatory support, business strategy and planning, market and demand forecasting, policy analysis, and engineering and technology strategy. We are often retained in high-stakes matters, such as multibillion-dollar mergers and acquisitions, new product introductions, major strategy and capital investment decisions, and complex litigation, the outcomes of which often have significant consequences for the parties involved. These matters often require independent analysis and, as a result, the parties involved must rely on outside experts. Our analytical strength enables us to reach objective, factual conclusions that help clients make important business and policy decisions and resolve critical disputes. Clients turn to us because we can provide highly credentialed and experienced economic and finance experts to address critical, tough assignments, with high-stakes outcomes.

We offer consulting services in two broad areas: litigation, regulatory, and financial consulting and management consulting. These two areas represented approximately 98% of our consolidated revenues for fiscal 2013. The remaining 2% came from our NeuCo subsidiary. We provide our services primarily through our highly credentialed and experienced staff of employee consultants. As of December 28, 2013, we employed 442 consultants, of which 327 were either executive vice presidents, vice presidents, principals, associate principals, senior associates, or consulting associates, of whom approximately 76%

have a doctorate or other advanced degree. Our employee consultants have backgrounds in a wide range of disciplines, including economics, business, corporate finance, materials sciences, accounting, and engineering. We are extremely selective in our hiring of consultants, recruiting from leading universities, industry, and government. Many of our employee consultants are nationally or internationally recognized as experts in their respective fields and have published scholarly articles, lectured extensively, and have been quoted in the press. They combine outstanding intellectual acumen with practical experience and in-depth understanding of industries and markets. To enhance the expertise we provide to our clients, we maintain close working relationships with a select group of renowned academic and industry non-employee experts.

Our business is diversified across multiple dimensions, including service offerings and vertical industry coverage, as well as areas of functional expertise, client base, and geography. Through 19 offices located internationally, we provide multiple services across 20 areas of functional expertise to hundreds of clients across 17 vertical industries. We believe this diversification reduces our dependence on any particular market, industry, or geographic area.

We provide consulting services to corporate clients and attorneys in a wide range of litigation and regulatory proceedings, providing high-quality research and analysis, expert testimony, and comprehensive support in litigation and regulatory proceedings in all areas of finance, accounting, economics, insurance, and forensic accounting and investigations. We also use our expertise in economics, finance, and business to offer law firms, businesses, and government agencies services related to class certification, damages analysis, expert reports and testimony, regulatory analysis, strategy development, valuation of tangible and intangible assets, risk management, and transaction support. In our management consulting services, we use our expertise in economics, finance, and business analysis to offer our clients such services as strategy development, performance improvement, corporate strategy and portfolio analysis, estimation of market demand, new product pricing strategies, valuation of intellectual property and other assets, assessment of competitors' actions, and analysis of new sources of supply. Our analytical expertise in advanced economic and financial methods is complemented by our in-depth expertise in specific industries, including banking and capital markets; chemicals and industrials; consumer products; energy and utilities; financial services; health care; insurance; life sciences; manufacturing; media; mining, metals and materials; oil and gas; real estate; retail; sports; telecommunications; and transportation.

We have completed thousands of engagements for clients around the world, including domestic and foreign companies; federal, state, and local domestic government agencies; governments of foreign countries; public and private utilities; and national and international trade associations. Our clients come from a broad range of industries, with our top 10 clients in fiscal 2013, fiscal 2012, and fiscal 2011 accounting for approximately 19%, 18%, and 23%, of our revenues, respectively, and no single client accounting for more than 5% of our revenues in each of these periods. We also work with many of the world's leading law firms. We experience a high level of repeat business, and in fiscal 2013, fiscal 2012, and fiscal 2011, approximately 87%, 95%, and 94%, respectively, of our revenues resulted from either ongoing engagements or new engagements for existing clients.

We deliver our services through an international network of 19 coordinated offices. Headquartered in Boston, Massachusetts, we have offices throughout North America and Europe.

Businesses are operating in an increasingly complex economic, legal, and regulatory environment. Our changing world economy has created immense challenges and opportunities for businesses. Companies across industry sectors are seeking new strategies appropriate for the current economic environment, as well as greater operational efficiencies. To accomplish these objectives, they must constantly gather, analyze, and use information wisely to assure that business decisions are well-informed. In addition, as markets have become global, companies have the opportunity to expand their presence throughout the world, which can expose them to increased competition and the uncertainties of foreign operations. Further, companies are increasingly relying on technological and

business innovations to improve efficiency, thus increasing the importance of strategically analyzing their businesses and developing and protecting new technology. The increasing complexity and changing nature of the business environment are also forcing governments to modify their regulatory strategies. These constant changes in the regulatory environment and the pro-regulatory stance in the U.S. have led to frequent litigation and interaction with government agencies as companies attempt to interpret and react to the implications of this changing environment. Furthermore, as the general business and regulatory environment becomes more complex, corporate litigation has also become more complicated, protracted, expensive, and important to the parties involved.

As a result, companies are increasingly relying on sophisticated economic and financial analysis to solve complex problems and improve decision-making. Economic and financial models provide the tools necessary to analyze a variety of issues confronting businesses, such as interpretation of sales data, effects of price changes, valuation of assets, assessment of competitors' activities, evaluation of new products, and analysis of supply limitations. Governments are also relying, to an increasing extent, on economic and finance theory to measure the effects of anticompetitive activity, evaluate mergers and acquisitions, change regulations, implement auctions to allocate resources, and establish transfer pricing rules. Finally, litigants and law firms are using economic and finance theory to help determine liability and to calculate damages in complex and high-stakes litigation. As the need for complex economic and financial analysis becomes more widespread, companies and governments are turning to outside consulting firms, such as ours, for access to the independent, specialized expertise, experience, and prestige that are not available to them internally. In addition, companies' strategic, organizational, and operational problems have gotten more acute as a result of the economic environment, and companies are relying on management consultants for help in analyzing, addressing, and solving strategic business problems and performance-related issues involving market supply demand dynamics, supply chain and sourcing, pricing, capital allocation, technology management, portfolio positioning, risk management, merger integration, and improving shareholder value.

Since 1965, we have been committed to providing sophisticated consulting services to our clients. We believe that the following factors have been critical to our success.

Strong Reputation for High-Quality Consulting; High Level of Repeat Business. Since 1965, we have been a leader in providing sophisticated economic analysis and original, authoritative advice to clients involved in complex litigation and regulatory proceedings, and we also provide management consulting services to companies facing strategic, organizational, and operational challenges. As a result, we believe we have established a strong reputation among leading law firms and business clients as a preferred source of expertise in economics, finance, business, and management consulting, as evidenced by our high level of repeat business. In fiscal 2013, fiscal 2012, and fiscal 2011, approximately 87%, 95%, and 94%, respectively, of our revenues resulted from ongoing engagements or new engagements from repeat clients. In addition, we believe our significant name recognition, which we developed as a result of our work on many high-profile litigation and regulatory engagements, has enhanced the development of our management consulting practice.

Highly Educated, Experienced, and Versatile Consulting Staff. We believe our most important asset is our base of employee consultants, particularly our senior employee consultants. Of our 442 employee consultants as of December 28, 2013, 327 were either executive vice presidents, vice presidents, principals, associate principals, senior associates, or consulting associates, of whom approximately 76% have a doctorate or other advanced degree. Many of these senior employee consultants are nationally or internationally recognized as experts in their respective fields. In addition to their expertise in a particular field, most of our employee consultants are able to apply their skills across numerous practice areas. This flexibility in staffing engagements is critical to our ability to apply our resources as needed to meet the demands of our clients. As a result, we seek to hire consultants who not only have strong analytical skills, but who are also creative, intellectually curious, and driven to develop expertise in new practice areas and industries.

International Presence. We deliver our services through an international network of 19 coordinated offices. Headquartered in Boston, Massachusetts, we have offices throughout North America and Europe. Many of our clients are multinational firms with issues that cross international boundaries, and we believe our international presence provides us with an advantage to address complex issues that span countries and continents. Our international presence also gives us access to many of the leading experts around the world on a variety of issues, allowing us to expand our knowledge base and areas of functional expertise. Revenues outside of the U.S. accounted for approximately 22%, 23%, and 26% of our total revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. See Note 13 of our Notes to Consolidated Financial Statements for a breakdown of our revenue and long-lived assets by country.

Diversified Business. Our business is diversified across multiple dimensions, including service offerings, vertical industry coverage, areas of functional expertise, client base, and geography. By maintaining expertise in multiple industries, we are able to offer clients creative and pragmatic advice tailored to their specific markets. By offering clients litigation, regulatory, financial, and management consulting services, we are able to satisfy an array of client needs, ranging from expert testimony for complex lawsuits to designing global business strategies. This broad range of expertise enables us to take an interdisciplinary approach to certain engagements, combining economists and experts in one area with specialists in other disciplines. We believe this diversification reduces our dependence on any particular market, industry, or geographic area. Furthermore, our litigation, regulatory, and financial consulting businesses are driven primarily by regulatory changes and high-stakes legal proceedings. Our diversity also enhances our expertise and the range of issues that we can address on behalf of clients.

Integrated Business. We manage our business on an integrated basis through our international network of 19 offices and 20 areas of functional expertise. Many of our practice areas are represented in several of our offices and are managed across geographic borders. We view these cross-border practices as integral to our success and key to our management approach. Our practices share not only staff but also consulting approaches and marketing strategies. When we acquire companies, our practice is to rapidly integrate systems, procedures, and people into our business model. In addition to sharing our intellectual property assets globally, we encourage geographic collaboration among our practices by including a consultant's overall contribution to our practices as a factor in determining the consultant's annual bonus.

Diversified Client Base. We have completed thousands of engagements for clients in a broad range of industries around the world. In fiscal 2013, fiscal 2012, and fiscal 2011, our top 10 clients accounted for approximately 19%, 18%, and 23% of our revenues, respectively, with no single client accounting for more than 5% of our revenues in each of these periods. Our clients are major firms across a multitude of industries that include banking and capital markets; chemicals and industrials; consumer products; energy and utilities; financial services; health care; insurance; life sciences; manufacturing; media; mining, metals, and materials; oil and gas; real estate; retail; sports; telecommunications; and transportation.

Established Corporate Culture. Our success results in part from our established corporate culture. We believe we attract consultants because of our 48-year history, our strong reputation, the credentials, experience, and reputations of our employee consultants, the opportunity to work on an array of matters with a broad group of renowned non-employee experts, and our collegial atmosphere where teamwork and collaboration are emphasized and valued by many clients.

Access to Leading Academic and Industry Experts. To enhance the expertise we provide to our clients and the depth and breadth of our insights, we maintain close working relationships with a select group of non-employee experts. Depending on client needs, we use non-employee experts for their specialized expertise, assistance in conceptual problem-solving, and expert witness testimony. We work regularly with renowned professors at such institutions as Cornell University, Georgetown University, Harvard University, the Massachusetts Institute of Technology, Northwestern University, Texas A&M University, the University of California at Berkeley, the University of California at Los Angeles, the University of Chicago, the University of Toronto, Yale University, and other leading universities. These

experts also generate business for us and provide us access to other leading academic and industry experts. By establishing affiliations with these prestigious experts, we further enhance our reputation as a leading source of sophisticated economic and financial analysis.

We offer services in two broad areas: litigation, regulatory, and financial consulting and management consulting. Together, these two service areas comprised approximately 98% of our consolidated revenues for fiscal 2013, and approximately 2% of our consolidated revenues came from our NeuCo subsidiary.

In our litigation, regulatory, and financial consulting practices, we typically work closely with law firms on behalf of one or more companies involved in litigation or regulatory proceedings in such areas as antitrust, damages, and labor and employment. Many of the lawsuits and regulatory proceedings in which we are involved are critical assignments with high-stakes outcomes, such as obtaining regulatory approval of a pending merger or analyzing possible damages awards in a class action case. The ability to formulate and effectively communicate powerful economic and financial arguments to courts and regulatory agencies is often critical to a successful outcome in litigation and regulatory proceedings. Our consultants combine uncommon analytical rigor with practical experience and in-depth understanding of industries and markets. Our analytical strength enables us to reach objective, factual conclusions that help our clients make important business and policy decisions and resolve critical disputes. Our consultants work with law firms, corporate counsel, and regulatory agencies to assist in developing the theory of the case and in preparing the testimony of expert witnesses from among our employees and from among our non-employee experts and others in academia. In addition, our consultants provide general litigation support, including reviewing legal briefs and assisting in the appeals process.

The following is a summary of the areas of functional expertise that we offer in litigation, regulatory, and financial consulting engagements. We provide services, such as economic expertise, analyses, and expert testimony, in these areas:

We believe our ability to combine expertise in advanced economic and financial methods with in-depth knowledge of particular industries is one of our key competitive strengths. By maintaining

expertise in certain industries, we provide clients practical advice tailored to their specific markets. This industry expertise, which we developed over decades of providing sophisticated consulting services to a diverse group of clients in many industries, differentiates us from many of our competitors. We believe that we have developed a strong reputation and substantial name recognition within specific industries, which has led to repeat business and new engagements from clients in those markets. While we provide services to clients in a wide variety of industries, we have particular expertise in the following industries:

We have completed thousands of engagements for clients around the world, including domestic and foreign corporations; federal, state, and local domestic government agencies; governments of foreign countries; public and private utilities; accounting firms; and national and international trade associations. Frequently, we work with major law firms who approach us on behalf of their clients. While we have particular expertise in a number of industries, we provide services to a diverse group of clients in a broad range of industries. No single client accounted for more than 5% of our revenues in fiscal 2013, fiscal 2012, and fiscal 2011. Our policy is to keep the identities of our clients confidential unless our work for the client is already publicly disclosed. Revenues outside of the U.S. accounted for approximately 22%, 23%, and 26% of our total revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. See Note 13 of our Notes to Consolidated Financial Statements for a breakdown of our revenue by country.

NeuCo, Inc. develops and markets a family of neural network software tools and complementary application consulting services that are currently focused on electric utilities. Although NeuCo had its origins in one of our consulting engagements, it is primarily a software company that operates independently from our consulting business. NeuCo's products and services are designed to help

utilities optimize the use of their power plants by improving heat rate, reducing emissions, overcoming operating constraints, and increasing output capability.

Our ownership interest in NeuCo was 55.89% for each of fiscal 2013, fiscal 2012 and fiscal 2011. Our ownership interest constitutes control under GAAP; therefore, NeuCo's financial results have been consolidated with ours and the portion of NeuCo's results allocable to its other owners is shown as "noncontrolling interest."

NeuCo's revenues included in our consolidated statements of operations for fiscal 2013, fiscal 2012, and fiscal 2011 totaled approximately $5.1 million, $5.5 million, and $6.2 million, respectively. NeuCo's net loss included in our consolidated statements of operations for fiscal 2013 was approximately $0.3 million. NeuCo's net income included in our consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.3 million and $0.2 million, respectively. NeuCo's net loss, net of amounts allocable to its other owners, included in the our consolidated statements of operations for fiscal 2013 was approximately $0.2 million. NeuCo's net income, net of amounts allocable to its other owners, included in our consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.2 million and $0.1 million, respectively.

On December 28, 2013, we had 597 employees, including 442 employee consultants, comprising 100 executive vice presidents or vice presidents, 227 other senior employee consultants (either principals, associate principals, senior associates, or consulting associates) and 115 junior consultants (either associates or analysts), as well as 155 administrative staff members. Executive vice presidents, vice presidents, and principals generally work closely with clients, supervise junior consultants, provide expert testimony on occasion, and seek to generate business for us. Principals, associate principals, senior associates, and consulting associates typically serve as project managers and handle complex research or business problem solving assignments. Consulting associates, associates, and analysts gather and analyze data, complete marketplace and academic literature research, and may perform statistical programming.

We derive most of our revenues directly from the services provided by our employee consultants. Our employee consultants were responsible for securing engagements that accounted for approximately 77%, 84%, and 84% of our total revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Our top five employee consultants generated approximately 17%, 18%, and 14% of our total revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Our employee consultants have backgrounds in many disciplines, including economics, business, corporate finance, accounting, materials sciences, and engineering. Approximately 76% of our senior employee consultants, consisting of vice presidents, principals, associate principals, senior associates, and consulting associates, have either a doctorate, master of business administration ("MBA"), or another advanced degree in addition to substantial management, technical, or industry expertise. We believe our financial results and reputation are directly related to the number and quality of our employee consultants.

We are highly selective in our hiring of consultants, recruiting primarily from a select group of leading universities and degree programs, industry, and government. We believe consultants choose to work for us because of our strong reputation; the credentials, experience, and reputations of our consultants; the opportunity to work on a diverse range of matters and with renowned non-employee experts; and our collegial atmosphere where teamwork and collaboration are emphasized and valued by many clients. We use a decentralized, team hiring approach. Our training and career development program for our employee consultants focuses on three areas: mentoring, seminars, and scheduled courses. This program is designed to complement on-the-job experience and an employee's pursuit of his or her own career development. New employee consultants participate in a structured program in which they are partnered with an assigned mentor. Through our ongoing seminar program, outside speakers make presentations and conduct discussions with our employee consultants on various topics. In addition, employee consultants are expected to discuss significant projects and cases, present academic research papers or business articles, or outline new analytical techniques or marketing

opportunities periodically at in-house seminars. We also provide scheduled courses designed to improve an employee's professional skills, such as written and oral presentation, marketing techniques, and business development. We also encourage our employee consultants to pursue their academic interests by writing articles for economic, business, and other journals.

Many of our vice presidents have signed non-solicitation agreements, which generally prohibit the employee from soliciting our clients or soliciting and/or hiring our employees for one year or longer following termination of the person's employment with us. In addition, many of the stock options we have issued between 2004 and 2008 contain a provision that they may only be exercised upon the execution of a non-competition agreement. We seek to align each vice president's interest with our overall interests, and many of our strongest contributors have an equity interest in us.

We maintain a discretionary bonus program through which we grant performance-based bonuses to our officers and other employees. In fiscal 2007, our shareholders approved a performance-based cash incentive plan for executive officers designed to preserve the deductibility of compensation paid to executive officers that would otherwise not be deductible under Section 162(m) of the Internal Revenue Code. On February 28, 2012, our Board of Directors amended this plan to extend its effective date until the annual meeting of our shareholders held in 2017 (or any special meeting in lieu thereof). In addition, during fiscal 2009, we implemented a long-term incentive program for certain key employees. Under this program, participants may receive a mixture of stock options, time-vesting restricted stock units, and performance-vesting restricted stock units. The program is designed to reward key employees and provide participants the opportunity to share in the long-term growth of our business. The Compensation Committee of our Board of Directors is responsible for approving equity compensation grants, approving the total bonuses to be distributed, establishing performance-based goals under these programs and plans each year, and determining the performance-based compensation earned each year by our executive officers under our cash incentive plan, with respect to which they can apply negative discretion. Our chief executive officer, in his discretion and in consultation with the Compensation Committee of our Board of Directors, approves the bonuses to be granted to our other employees, based on recommendations of the various leaders supervising the employees' work.

In addition, we work closely with a select group of non-employee experts from leading universities and industry. These experts supplement the work of our employee consultants and generate business for us. In fiscal 2013, fiscal 2012, and fiscal 2011, five of our top non-employee experts were responsible for securing engagements that accounted for approximately 15%, 9%, and 8%, respectively, of our revenues in those periods. We believe these experts choose to work with us because of the interesting and challenging nature of our work, the opportunity to work with our quality-oriented consultants, and the financially rewarding nature of the work. Several non-employee experts, generally comprising the more active of those with whom we work, have entered into restrictive covenant contracts with us of varying lengths, which, in some cases, include non-competition agreements.

The majority of our revenues depend on the number of hours worked by our employee consultants. As a result, we experience certain seasonal effects that impact our revenue, such as holiday seasons and the summer vacation season.

We rely to a significant extent on the efforts of our employee consultants, particularly our vice presidents and principals, to market our services. We encourage our employee consultants to generate new business from both existing and new clients, and we reward our employee consultants with increased compensation and promotions for obtaining new business. In pursuing new business, our consultants emphasize our institutional reputation, experience, and client service, while also promoting the expertise of the particular employees who will work on the matter. Many of our consultants have published articles in industry, business, economic, legal, or scientific journals, and have made speeches and presentations at industry conferences and seminars, which serve as a means of attracting new business and enhancing their reputations. On occasion, employee consultants work with one or more non-employee experts to market our services. In addition, we rely upon business development

professionals to ensure that the value of our litigation consulting service offerings is fully realized in the marketplace. They are focused on deepening and broadening client relationships with law firms and general counsels, ensuring that both existing and potential clients have access to our broad array of services, as well as helping to bring the best talent to any given assignment.

We supplement the personal marketing efforts of our employee consultants with firm-wide initiatives. We rely primarily on our reputation and client referrals for new business and undertake traditional marketing activities. We regularly organize seminars for existing and potential clients featuring panel members that include our employee consultants, non-employee experts, and leading government officials. We have an extensive set of brochures organized around our service areas, which describe our experience and capabilities. We also provide information about our services on our corporate website. We distribute publications to existing and potential clients highlighting emerging trends and noteworthy engagements. Because existing clients are an important source of repeat business and referrals, we communicate regularly with our existing clients to keep them informed of developments that affect their markets and industries.

We derive the majority of new business from new engagements from existing clients. We have worked with leading law firms across the globe and believe we have developed a reputation among law firms as a preferred source of sophisticated economic advice for litigation and regulatory work. For our management consulting services, we also rely on referrals from existing clients, and supplement referrals with a significant amount of direct marketing to new clients through conferences, seminars, publications, presentations, and direct solicitations.

It is important to us that we conduct business ethically and in accordance with industry standards and our own rigorous professional standards. We carefully consider the pursuit of each specific market, client, and engagement.

The market for economic and management consulting services is intensely competitive, highly fragmented, and subject to rapid change. In general, there are few barriers to entry into our markets, and we expect to face additional competition from new entrants into the economic and management consulting industries. In the litigation, regulatory, and financial consulting markets, we compete primarily with other economic consulting firms and individual academics. We believe the principal competitive factors in this market are reputation, analytical ability, industry expertise, size, and service. In the management consulting market, we compete primarily with other business and management consulting firms, specialized or industry-specific consulting firms, the consulting practices of large accounting firms, and the internal professional resources of existing and potential clients. We believe the principal competitive factors in this market are reputation, industry expertise, analytical ability, service, and price.

Our operations are subject to a number of risks. You should carefully read and consider the following risk factors, together with all other information in this report, in evaluating our business. If any of these risks, or any risks not presently known to us or that we currently believe are not significant, develops into an actual event, then our business, financial condition, and results of operations could be adversely affected. If that happens, the market price of our common stock could decline, and you may lose all or part of your investment.

Our business consists primarily of the delivery of professional services, and, accordingly, our success depends heavily on the efforts, abilities, business generation capabilities, and project execution capabilities of our employee consultants. In particular, our employee consultants' personal relationships with our clients are a critical element in obtaining and maintaining client engagements. If we lose the services of any employee consultant or group of employee consultants, or if our employee consultants fail to generate business or otherwise fail to perform effectively, that loss or failure could adversely affect our revenues and results of operations. Our employee consultants generated engagements that accounted for approximately 77%, 84%, and 84% of our revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Our top five employee consultants generated approximately 17%, 18%, and 14% of our revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively.

We do not have non-competition agreements with a majority of our employee consultants, and they can terminate their relationships with us at will and without notice. The non-competition and non-solicitation agreements that we have with some of our employee consultants offer us only limited protection and may not be enforceable in every jurisdiction. In the event that an employee leaves, some clients may decide that they prefer to continue working with the employee rather than with us. In the event an employee departs and acts in a way that we believe violates the employee's non-competition or non-solicitation agreement, we will consider any legal remedies we may have against such person on a case-by-case basis. We may decide that preserving cooperation and a professional relationship with the former employee or clients that worked with the employee, or other concerns, outweigh the benefits of any possible legal recovery.

Our business could suffer if we are unable to hire and retain additional qualified consultants as employees

Our business continually requires us to hire highly qualified, highly educated consultants as employees. Our failure to recruit and retain a significant number of qualified employee consultants could limit our ability to accept or complete engagements and adversely affect our revenues and results of operations. Relatively few potential employees meet our hiring criteria, and we face significant competition for these employees from our direct competitors, academic institutions, government agencies, research firms, investment banking firms, and other enterprises. Many of these competing employers are able to offer potential employees greater compensation and benefits or more attractive lifestyle choices, career paths, or geographic locations than we can. Competition for these employee consultants has increased our labor costs, and a continuation of this trend could adversely affect our margins and results of operations.

Our ability to secure new engagements and hire qualified consultants as employees depends heavily on our overall reputation as well as the individual reputations of our employee consultants and principal non-employee experts. Because we obtain a majority of our new engagements from existing clients, any client that is dissatisfied with our performance on a single matter could seriously impair our ability to secure new engagements. Given the frequently high-profile nature of the matters on which we work, including work before and on behalf of government agencies, any factor that diminishes our reputation or the reputations of any of our employee consultants or non-employee experts could make it substantially more difficult for us to compete successfully for both new engagements and qualified consultants.

We depend on our relationships with our non-employee experts. In fiscal 2013, fiscal 2012, and fiscal 2011, our top five non-employee experts generated engagements that accounted for approximately 15%, 9%, and 8% of our revenues in those periods, respectively. We believe that these experts are highly regarded in their fields and that each offers a combination of knowledge, experience, and expertise that would be very difficult to replace. We also believe that we have been able to secure some

engagements and attract consultants in part because we can offer the services of these experts. Most of these experts can limit their relationships with us at any time for any reason. These reasons could include affiliations with universities with policies that prohibit accepting specified engagements, termination of exclusive relationships, the pursuit of other interests, and retirement.

In many cases we seek to include restrictive covenant agreements in our agreements with our non-employee experts, which could include non-competition agreements, non-solicitation agreements and non-hire agreements. The limitation or termination of any of their relationships with us, or competition from any of them after these agreements expire, could harm our reputation, reduce our business opportunities and adversely affect our revenues and results of operations. These restrictive covenant agreements that we may have with some of our non-employee experts offer us only limited protection and may not be enforceable in every jurisdiction. In the event that non-employee experts leave, clients working with these non-employee experts may decide that they prefer to continue working with them rather than with us. In the event a non-employee expert departs and acts in a way that we believe violates the expert's restrictive covenant agreements, we will consider any legal and equitable remedies we may have against such person on a case-by-case basis. We may decide that preserving cooperation and a professional relationship with the former non-employee expert or clients that worked with the non-employee expert, or other concerns, outweigh the benefits of any possible legal action or recovery.

To meet our long-term growth targets, we need to establish ongoing relationships with additional non-employee experts who have reputations as leading experts in their fields. We may be unable to establish relationships with any additional non-employee experts. In addition, any relationship that we do establish may not help us meet our objectives or generate the revenues or earnings that we anticipate.

Many of our engagements depend upon disputes, proceedings, or transactions that involve our clients. Our clients may decide at any time to seek to resolve the dispute or proceeding, abandon the transaction, or file for bankruptcy. Our engagements can therefore terminate suddenly and without advance notice to us. If an engagement is terminated unexpectedly, our employee consultants working on the engagement could be underutilized until we assign them to other projects. In addition, because much of our work is project-based rather than recurring in nature, our consultants' utilization depends on our ability to secure additional engagements on a continual basis. Accordingly, the termination or significant reduction in the scope of a single large engagement could reduce our utilization and have an immediate adverse impact on our revenues and results of operations.

Potential conflicts of interests may preclude us from accepting some engagements

We provide our services primarily in connection with significant or complex transactions, disputes, or other matters that are usually adversarial or that involve sensitive client information. Our engagement by a client may preclude us from accepting engagements with the client's competitors or adversaries because of conflicts between their business interests or positions on disputed issues or other reasons. Accordingly, the nature of our business limits the number of both potential clients and potential engagements. Moreover, in many industries in which we provide consulting services, such as in the telecommunications industry, there has been a continuing trend toward business consolidations and strategic alliances. These consolidations and alliances reduce the number of potential clients for our services and increase the chances that we will be unable to continue some of our ongoing engagements or accept new engagements as a result of conflicts of interests.

Deterioration of global economic conditions, global market and credit conditions, and regulatory and legislative changes affecting our clients, practice areas, or competitors could have an impact on our business

Overall global economic conditions and global market and credit conditions in the industries we service can negatively impact the market for our services. These factors are outside of our control and

include the availability of credit, the costs and terms of borrowing, merger and acquisition activity, and general economic factors and business conditions.

Similarly, many of our clients are in highly regulated industries. Regulatory and legislative changes in these industries could also impact the market for our service offerings and could render our current service offerings obsolete, reduce the demand for our services, or impact the competition for consulting and expert services. For example, potential changes in the patent laws could have a significant impact on our intellectual property practice. We are not able to predict the positive or negative effects that future events or changes to the U.S. or international business environment could have on our operations.

We depend on our antitrust and mergers and acquisitions consulting business

We derive a significant amount of our revenues from engagements related to antitrust and mergers and acquisitions activities. Any substantial reduction in the number or size of our engagements in these areas could adversely affect our revenues and results of operations. Adverse changes in general economic conditions, particularly conditions influencing the merger and acquisition activity of larger companies, could adversely affect engagements in which we assist clients in proceedings before the U.S. Department of Justice, the U.S. Federal Trade Commission, and various foreign antitrust authorities. For example, global economic recessions have resulted in, and may in the future result in, reduced merger and acquisition activity levels. Any of these reductions in activity level would adversely affect our revenues and results of operations.

Our failure to execute our business strategy or manage future growth successfully could adversely affect our revenues and results of operations

Any failure on our part to execute our business strategy or manage future growth successfully could adversely affect our revenues and results of operations. In the future, we could open offices in new geographic areas, including foreign locations, and expand our employee base as a result of internal growth and acquisitions. Opening and managing new offices often requires extensive management supervision and increases our overall selling, general, and administrative expenses. Expansion creates new and increased management, consulting, and training responsibilities for our employee consultants. Expansion also increases the demands on our internal systems, procedures, and controls, and on our managerial, administrative, financial, marketing, and other resources. We depend heavily upon the managerial, operational, and administrative skills of our executive officers to manage our expansion and business strategy. New responsibilities and demands may adversely affect the overall quality of our work.

Competition from other litigation, regulatory, financial, and management consulting firms could hurt our business

The market for litigation, regulatory, financial, and management consulting services is intensely competitive, highly fragmented, and subject to rapid change. We may be unable to compete successfully with our existing competitors or with any new competitors. In general, there are few barriers to entry into our markets, and we expect to face additional competition from new entrants into the economic and management consulting industries. In the litigation, regulatory, and financial consulting markets, we compete primarily with other economic and financial consulting firms and individual academics. In the management consulting market, we compete primarily with other business and management consulting firms, specialized or industry-specific consulting firms, the consulting practices of large accounting firms, and the internal professional resources of existing and potential clients. Many of our competitors have national or international reputations as well as significantly greater personnel, financial, managerial, technical, and marketing resources than we do, which could enhance their ability to respond more quickly to technological changes, finance acquisitions, and fund internal growth. Some of our competitors also have a significantly broader geographic presence and resources than we do.

We derive a portion of our revenues from a limited number of large engagements. If we do not obtain a significant number of new large engagements each year, our business, financial condition, and results of operations could suffer. Our 10 largest engagements accounted for approximately 13%, 11%, and 14% of our revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Our top 10 clients accounted for approximately 19%, 18%, and 23% of our revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. In general, the volume of work we perform for any particular client varies from year to year, and due to the specific engagement nature of our practice, a major client in one year may not hire us in the following year.

Our engagements may result in professional liability and we may be subject to other litigation, claims or assessments

Our services typically involve difficult analytical assignments and carry risks of professional and other liability. Many of our engagements involve matters that could have a severe impact on a client's business, cause the client to lose significant amounts of money, or prevent the client from pursuing desirable business opportunities. Accordingly, if a client is dissatisfied with our performance, the client could threaten or bring litigation in order to recover damages or to contest its obligation to pay our fees. Litigation alleging that we performed negligently, disclosed client confidential information, or otherwise breached our obligations to the client could expose us to significant liabilities to our clients and other third parties and tarnish our reputation.

Despite our efforts to prevent litigation, from time to time we are party to various lawsuits, claims, or assessments in the ordinary course of business. Disputes may arise, for example, from business acquisitions, employment issues, regulatory actions, and other business transactions. The costs and outcome of any lawsuits or claims could have a material adverse effect on us.

Fluctuations in our quarterly revenues and results of operations could depress the market price of our common stock

We may experience significant fluctuations in our revenues and results of operations from one quarter to the next. If our revenues or net income in a quarter falls below the expectations of securities analysts or investors, the market price of our common stock could fall significantly. Our results of operations in any quarter can fluctuate for many reasons, including:

Because we generate a majority of our revenues from consulting services that we provide on an hourly fee basis, our revenues in any period are directly related to the number of our employee consultants, their billing rates, and the number of billable hours they work in that period. We have a limited ability to increase any of these factors in the short term. Accordingly, if we underutilize our consultants during one part of a fiscal period, we may be unable to compensate by augmenting revenues during another part of that period. In addition, we are occasionally unable to utilize fully any additional consultants that we hire, particularly in the quarter in which we hire them. Moreover, a significant majority of our operating expenses, primarily office rent and salaries, are fixed in the short term. As a result, any failure of our revenues to meet our projections in any quarter could have a disproportionate adverse effect on our net income. For these reasons, we believe our historical results of operations are not necessarily indicative of our future performance.

We regularly evaluate opportunities to acquire other businesses. The expenses we incur evaluating and pursuing acquisitions could adversely affect our results of operations. If we acquire a business, we may be unable to manage it profitably or successfully integrate its operations with our own. Moreover, we may be unable to realize the financial, operational, and other benefits we anticipate from these acquisitions or any other acquisition. Many potential acquisition targets do not meet our criteria, and, for those that do, we face significant competition for these acquisitions from our direct competitors, private equity funds, and other enterprises. Competition for future acquisition opportunities in our markets could increase the price we pay for businesses we acquire and could reduce the number of potential acquisition targets. Further, acquisitions may involve a number of special financial and business risks, such as:

Our clients include some companies that may from time to time encounter financial difficulties, particularly during a downward trend in the economy or may dispute the services we provide. If a client's financial difficulties become severe or a dispute arises, the client may be unwilling or unable to pay our invoices in the ordinary course of business, which could adversely affect collections of both our accounts receivable and unbilled services. On occasion, some of our clients have entered bankruptcy, which has prevented us from collecting amounts owed to us. The bankruptcy of a client with a substantial accounts receivable could have a material adverse effect on our financial condition and results of operations. Historically, a small number of clients who have paid sizable invoices have later declared bankruptcy, and a court determination that we were not properly entitled to any of those payments may require repayment of some or all of them, which could adversely affect our financial condition and results of operations.

Additionally, from time to time, we may derive a significant amount of revenue from government agencies in the United States. Because we may derive a significant percentage of our revenue from contracts with the federal government, changes in federal government budgetary priorities could directly affect our financial performance. This could result in the cancellation of contracts and/or the incurrence of substantial costs without reimbursement under our contracts with the U.S. Government, which could have a negative effect on our business, financial condition, results of operations and cash flows.

Our entry into new lines of business could adversely affect our results of operations

If we attempt to develop new practice areas or lines of business outside our core litigation, regulatory, financial, and management consulting services, those efforts could harm our results of operations. Our efforts in new practice areas or new lines of business involve inherent risks, including risks associated with inexperience and competition from mature participants in the markets we enter. Our inexperience in these new practice areas or lines of business may result in costly decisions that could harm our business.

Our international operations carry special financial and business risks, including:

If our international revenues increase relative to our total revenues, these factors could have a more pronounced effect on our operating results.

Our performance could be affected if employees and non-employee experts default on loans

We utilize forgivable loans and term loans with some of our employees and non-employee experts, other than our executive officers, as a way to attract and retain them. A portion of the term loans are collateralized. Defaults under these loans could have a material adverse effect on our consolidated statements of operations, financial condition and liquidity.

The market price of our common stock has fluctuated widely and may continue to do so. For example, from December 30, 2012, to December 28, 2013, the trading price of our common stock

ranged from a high of $23.10 per share to a low of $15.64 per share. Many factors could cause the market price of our common stock to rise and fall. Some of these factors are:

In addition, the stock market often experiences significant price and volume fluctuations. These fluctuations are often unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our common stock. When the market price of a company's stock drops significantly, shareholders often institute securities class action litigation against that company. Any litigation against us could cause us to incur substantial costs, divert the time and attention of our management and other resources, or otherwise harm our business.

Our stock repurchase program could affect the market price of our common stock and increase its volatility.

On February 13, 2014, we announced that our Board of Directors authorized the repurchase of up to $15 million of our outstanding common stock, in addition to the $1.4 million remaining under our existing stock repurchase program. Under these stock repurchase programs, we are authorized to repurchase, from time-to-time, shares of our outstanding common stock on the open market or in privately negotiated transactions. The timing and amount of stock repurchases will be determined based upon our evaluation of market conditions and other factors. The stock repurchase program may be suspended, modified or discontinued at any time, and we have no obligation to repurchase any amount of our common stock under the program. Repurchases pursuant to our stock repurchase program could affect the market price of our common stock and increase its volatility. Any termination of our stock repurchase programs could cause a decrease in the market price of our common stock price, and the existence of a stock repurchase program could cause our stock price to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity of our common stock. There can be no assurance that any stock repurchases under these programs will enhance stockholder value because the market price of our common stock may decline below the levels at which those repurchases were made. Although our stock repurchase program is intended to enhance long-term stockholder value, short-term fluctuations in the market price of our common stock could reduce the program's effectiveness.

We have a revolving line of credit with our bank for $125.0 million. The amounts available under this line of credit are constrained by various financial covenants and reduced by certain letters of credit outstanding. Our loan agreement with the bank will mature on April 24, 2018. The degree to which we are leveraged could adversely affect our ability to obtain further financing for working capital, acquisitions or other purposes and could make us more vulnerable to industry downturns and competitive pressures. Our ability to secure short-term and long-term debt or equity financing in the future will depend on several factors, including our future profitability, the levels of our debt and equity, restrictions under our existing revolving line of credit, and the overall credit and equity market environments.

We may need to take material write-offs for the impairment of goodwill and other intangible assets, including if our market capitalization declines

As further described in Note 1 of our Notes to Consolidated Financial Statements, goodwill and intangible assets with indefinite lives are monitored annually for impairment, or more frequently, if events or circumstances exist that would more likely than not reduce our fair value below our carrying amount. In performing the first step of the goodwill impairment testing and measurement process, we compare our entity-wide estimated fair value to net book value to identify potential impairment. We estimate the entity-wide fair value utilizing our market capitalization, plus an appropriate control premium. We have utilized a control premium that considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If we determine through the impairment evaluation process that goodwill has been impaired, we would record the impairment charge in our consolidated statements of operations.

We had no impairment losses related to goodwill during fiscal 2013 as there were no events or circumstances that would more likely than not reduce our fair value below our carrying amount.

When we performed our annual impairment test in the fourth quarter of fiscal 2012, our net book value exceeded our market capitalization plus an estimated control premium. Therefore, we were required to perform the second step of the goodwill impairment test. During the process of conducting the second step of the annual goodwill impairment test in the fourth quarter of fiscal 2012, we identified significant unrecognized intangible assets. The combination of these hypothetical unrecognized intangible assets and other hypothetical unrecognized fair value changes to the carrying values of other assets and liabilities, together with the lower fair value calculated in the first step of the annual impairment test, resulted in a non-cash goodwill impairment charge of $71.4 million in the fourth quarter of fiscal 2012.

In the future, if our market capitalization plus an estimated control premium is below our net book value for a period we consider to be other-than-temporary, we may be required to record an impairment of goodwill either as a result of our annual assessment performed in the fourth quarter of each year or in a future quarter if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. A goodwill impairment charge would have the effect of decreasing our earnings in such period. If we are required to take a substantial impairment charge, our operating results would be materially adversely affected in such period, though such a charge would have no impact on cash flows or working capital.

Fluctuations in the types of service contracts we enter into may adversely impact revenue and results of operations

We derive a portion of our revenues from fixed-price contracts. We derived approximately 13%, 15%, and 22% of revenues from fixed-price engagements in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. These contracts are more common in our management consulting area, and would likely grow in number with expansion of that area. Fluctuations in the mix between time-and-material contracts, fixed-price contracts and arrangements with fees tied to performance-based criteria may result in fluctuations of revenue and results of operations. In addition, if we fail to estimate accurately the resources required for a fixed-price project or fail to satisfy our contractual obligations in a manner consistent with the project budget, we might generate a smaller profit or incur a loss on the project. On occasion, we have had to commit unanticipated additional resources to complete projects, and we may have to take similar action in the future, which could adversely affect our revenues and results of operations.

We could incur substantial costs protecting our proprietary rights from infringement or defending against a claim of infringement

As a professional services organization, we rely on non-competition and non-solicitation agreements with many of our employees and non-employee experts to protect our proprietary rights.

These agreements, however, may offer us only limited protection and may not be enforceable in every jurisdiction. In addition, we may incur substantial costs trying to enforce these agreements.

Our services may involve the development of custom business processes or solutions for specific clients. In some cases, the clients retain ownership or impose restrictions on our ability to use the business processes or solutions developed from these projects. Issues relating to the ownership of business processes or solutions can be complicated, and disputes could arise that affect our ability to resell or reuse business processes or solutions we develop for clients.

In recent years, there has been significant litigation in the U.S. involving patents and other intellectual property rights. We could incur substantial costs in prosecuting or defending any intellectual property litigation, which could adversely affect our operating results and financial condition.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to obtain and use information that we regard as proprietary. Litigation may be necessary in the future to enforce our proprietary rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Any such resulting litigation could result in substantial costs and diversion of resources and could adversely affect our business, operating results and financial condition. Any failure by us to protect our proprietary rights, or any court determination that we have either infringed or lost ownership of proprietary rights could adversely affect our business, operating results and financial condition.

Insurance and claims expenses could significantly reduce our profitability

We are exposed to claims related to group health insurance. We self-insure a portion of the risk associated with these claims. If the number or severity of claims increases, or we are required to accrue or pay additional amounts because the claims prove to be more severe than our original assessment, our operating results would be adversely affected. Our future insurance and claims expense might exceed historical levels, which could reduce our earnings. We expect to periodically assess our self-insurance strategy. We are required to periodically evaluate and adjust our claims reserves to reflect our experience. However, ultimate results may differ from our estimates, which could result in losses over our reserved amounts. We maintain individual and aggregate medical plan stop loss insurance with licensed insurance carriers to limit our ultimate risk exposure for any one case and for our total liability.

Many businesses are experiencing the impact of increased medical costs as well as greater variability in ongoing costs. As a result, our insurance and claims expense could increase, or we could raise our self-insured retention when our policies are renewed. If these expenses increase or we experience a claim for which coverage is not provided, results of our operations and financial condition could be materially and adversely affected.

Our amended and restated articles of organization and amended and restated by-laws and Massachusetts law contain provisions that could have anti-takeover effects and that could discourage, delay, or prevent a change in control or an acquisition that our shareholders may find attractive. These provisions may also discourage proxy contests and make it more difficult for our shareholders to take some corporate actions, including the election of directors. These provisions could limit the price that investors might be willing to pay for shares of our common stock.

In the aggregate, as of December 28, 2013, we leased approximately 310,218 square feet of office space in locations around the world. Additionally, NeuCo leases approximately 8,965 square feet of office space. We have subleased to other companies approximately 65,059 square feet of our leased office space.

All of our offices are electronically linked and have access to our core consulting tools. We believe our existing facilities are adequate to meet our current requirements and that suitable space will be available as needed.

On February 24, 2014, we entered into a new lease with BP Hancock LLC, as landlord, for the 9th and 10th floors (a total of 57,602 square feet) of the same office building at 200 Clarendon Street, Boston, Massachusetts in which our Boston offices are currently located. The lease's base term will expire ten years from the date that we begin paying fixed rent under the lease and, subject to certain conditions, will be extendible by us for two five-year periods. The annual fixed rent for this office space (which does not include customary operating costs and expenses) will be $42 per square foot, or approximately $2.4 million, for the first year of the lease's base term and will increase at the rate of $1.00 per square foot during the remainder of the lease's base term. The lease gives us a right of first refusal to rent certain additional office space in the office building if it becomes available. The performance of our obligations under the lease is secured by a $1 million letter of credit.

Concurrently with our entering into this new lease, we also entered into an amendment of our existing lease with BP Hancock LLC, as landlord, for the office space we currently rent in the office building described above, which currently expires on March 31, 2015. Except with respect to 25,099 square feet of office space covered by this lease, the amendment either extends the term of this lease to, or if prior to March 31, 2015 terminates this lease on, the day prior to the date that the we begin paying fixed rent under the new lease described above. If the term of the existing lease is extended, the amendment provides that the base rent payable under this lease during the extension period will be $2.4 million per year.

We currently expect that the term of the new lease will commence, and the relocation of our Boston offices to the 9th and 10th floors of the office building at 200 Clarendon Street, Boston, Massachusetts will occur, sometime in the second quarter of fiscal 2015.

Item 5—Market for Registrant's Common Equity, Related Shareholder Matters and Issuer Purchases of Equity Securities

Market Information. We first offered our common stock to the public on April 23, 1998. Our common stock is traded on the NASDAQ Global Select Market under the symbol CRAI. The following table provides the high and low sales prices of our common stock as reported on the NASDAQ Global Select Market for the periods indicated.

Shareholders. We had approximately 115 holders of record of our common stock as of March 6, 2014. This number does not include shareholders for whom shares were held in a "nominee" or "street" name.

Dividends. We have not paid any cash dividends in the past and we do not anticipate paying any cash dividends in the foreseeable future. In addition, the terms of our bank line of credit place restrictions on our ability to pay cash dividends on our common stock.

Repurchases of Equity Securities. The following table provides information about our repurchases of shares of our common stock during the quarter ended December 28, 2013. During that period, we did not act in concert with any affiliate or any other person to acquire any of our common stock and, accordingly, we do not believe that purchases by any such affiliate or other person (if any) are reportable in the following table. For purposes of this table, we have divided the quarter into three periods of four weeks, four weeks and five weeks to coincide with our reporting periods during the fourth quarter of fiscal 2013.

connection with the vesting of shares of restricted stock that occurred during the indicated period, at an average price per share of $18.43.

(2): On August 30, 2011, we announced that our Board of Directors approved a share repurchase program of up to $7.5 million of our common stock. On February 22, 2012 and August 10, 2012, our Board of Directors authorized the repurchase of up to an additional $4.45 million and $5.0 million, respectively, of our common stock under these programs. During the four weeks ended November 23, 2013 and the five weeks ended December 28, 2013, we repurchased and retired 66,174 shares and 19,019 shares, respectively, under this program at an average price per share of $18.29 and $18.51, respectively. Approximately $1.4 million was available for future repurchases under these programs as of December 28, 2013. On February 13, 2014, we announced that our Board of Directors approved a share repurchase program of up to an additional $15.0 million of our common stock. We expect to continue to repurchase shares under these programs.

(1): On June 9, 2009, we purchased substantially all of the assets of Marakon Associates, Inc.

On January 31, 2013, we announced that an approximate 40-person litigation consulting team had joined us, effective February 1, 2013. Under the terms of the transaction, we acquired certain intangible assets, accounts receivable, and certain client projects currently underway.

These acquisitions were accounted for under the purchase accounting method, and the results of operations for these acquisitions have been included in the accompanying statements of operations from the date of acquisition.

(2): Basic net income (loss) per share represents net income (loss) divided by the weighted average shares of common stock outstanding during the period. Diluted net income per share represents net income divided by the weighted average shares of common stock and common stock equivalents outstanding during the period, if applicable. Weighted average shares used in diluted net income per share include common stock equivalents arising from stock options, unvested restricted stock, and shares underlying our debentures using the treasury stock method. All common stock equivalents were excluded in fiscal 2012 and the five weeks ended January 1, 2011 and January 2, 2010 because they were antidilutive due to the net loss.

Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations

We are a worldwide leading economic, financial, and management consulting firm that applies advanced analytic techniques and in-depth industry knowledge to complex engagements for a broad range of clients.

We derive revenues principally from professional services rendered by our employee consultants. In most instances, we charge clients on a time-and-materials basis and recognize revenues in the period when we provide our services. We charge consultants' time at hourly rates, which vary from consultant to consultant depending on a consultant's position, experience, expertise, and other factors. We derive a portion of our revenues from fixed-price contracts. Revenues from fixed-price engagements are recognized using a proportional performance method based on the ratio of costs incurred, substantially all of which are labor-related, to the total estimated project costs. We derived approximately 13%, 15%, and 22% of our revenues from fixed-price engagements in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. We generate substantially all of our professional services fees from the work of our own employee consultants and a portion from the work of our non-employee experts. Factors that affect our professional services revenues include the number and scope of client engagements, the number of consultants we employ, the consultants' billing rates, and the number of hours our consultants work. Revenues also include reimbursements, which include travel and other out-of-pocket expenses, outside consultants, and other reimbursable expenses.

Our costs of services include the salaries, bonuses, share-based compensation expense, and benefits of our employee consultants. Our bonus program awards discretionary bonuses based on our revenues and profitability and individual performance. Costs of services also include out-of-pocket and other expenses, and the salaries of support staff whose time is billed directly to clients, such as librarians, editors, and programmers. Selling, general, and administrative expenses include salaries, bonuses, share-based compensation expense, and benefits of our administrative and support staff, fees to non-employee experts for generating new business, office rent, marketing, and other costs.

We derive the majority of our revenues from the number of hours worked by our employee consultants. Our utilization of those employee consultants is one key indicator that we use to measure our operating performance. We calculate utilization by dividing the total hours worked by our employee consultants on engagements during the measurement period by the total number of hours that our employee consultants were available to work during that period. Utilization was 73%, 68%, and 74% for fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Select underperforming practice areas, including our Chemicals practice and Middle East operations, affected our overall performance in fiscal 2012. In connection with the restructuring plan we committed to in the third quarter of fiscal 2012, we eliminated our Chemicals practice, closed our Middle East operations and repositioned other select underperforming practice areas, amongst other actions. The decrease in utilization in fiscal 2012 compared to fiscal 2011 reflects this underperformance and these restructuring actions.

We experience certain seasonal effects that impact our revenue. Concurrent vacations or holidays taken by a large number of consultants can adversely impact our revenue. For example, the third quarter typically experiences fewer billable hours, as that is the summer vacation season for most of our offices. Also, historically we have experienced fewer billable hours in our fiscal quarter that includes the holiday season, which was the fourth quarter in each of fiscal 2013, fiscal 2012 and fiscal 2011.

Revenues outside of the U.S. accounted for approximately 22%, 23%, and 26% of our total revenues in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Revenue by country is detailed in Note 13 to our Notes to Consolidated Financial Statements.

Our ownership interest in NeuCo is 55.89% and constitutes control under GAAP; therefore, NeuCo's financial results have been consolidated with ours and the portion of NeuCo's results allocable to its other owners is shown as "noncontrolling interest."

NeuCo's revenues included in our consolidated statements of operations for fiscal 2013, fiscal 2012, and fiscal 2011 totaled approximately $5.1 million, $5.5 million, and $6.2 million, respectively. NeuCo's net loss included in our consolidated statements of operations for fiscal 2013 was approximately $0.3 million. NeuCo's net income included in our consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.3 million and $0.2 million, respectively. NeuCo's net loss, net of amounts allocable to its other owners, included in our consolidated statements of operations for fiscal 2013 was approximately $0.2 million. NeuCo's net income, net of amounts allocable to its other owners, included in our consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.2 million and $0.1 million, respectively.

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, as well as related disclosure of contingent assets and liabilities. Estimates in these consolidated financial statements include, but are not limited to, accounts and unbilled receivable allowances, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long-lived assets and goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, accrued compensation, accrued exit costs, and other accrued expenses. These items are monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates if our assumptions based on past experience or our other assumptions do not turn out to be substantially accurate.

A summary of the accounting policies that we believe are most critical to understanding and evaluating our financial results is set forth below. This summary should be read in conjunction with our consolidated financial statements and the related notes included in Item 8 of this annual report on Form 10-K.

Revenue Recognition and Accounts Receivable Allowances. We derive substantially all of our revenues from the performance of professional services. The contracts that we enter into and operate under specify whether the engagement will be billed on a time-and-materials or fixed-price basis. These engagements generally last three to six months, although some of our engagements can be much longer in duration. Each contract must be approved by one of our vice presidents.

We recognize substantially all of our revenues under written service contracts with our clients where the fee is fixed or determinable, as the services are provided, and only in those situations where collection from the client is reasonably assured. In certain cases we provide services to our clients without sufficient contractual documentation, or fees are tied to performance-based criteria, which require us to defer revenue in accordance with U.S. GAAP. In these cases, these amounts are fully reserved until all criteria for recognizing revenue are met.

Our revenues include projects secured by our non-employee experts as well as projects secured by our employees. We recognize all project revenue on a gross basis based on the consideration of the criteria set forth in Accounting Standards Codification ("ASC") Topic 605-45, Principal Agent Considerations.

Most of our revenue is derived from time-and-materials service contracts. Revenues from time-and-materials service contracts are recognized as the services are provided based upon hours worked and contractually agreed-upon hourly rates, as well as indirect fees based upon hours worked.

Revenues from a majority of our fixed-price engagements are recognized on a proportional performance method based on the ratio of costs incurred, substantially all of which are labor-related, to the total estimated project costs. We derived approximately 13%, 15%, and 22% of revenues from fixed-price engagements in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. In general, project costs are classified in costs of services and are based on the direct salary of the consultants on the engagement plus all direct expenses incurred to complete the engagement, including any amounts billed to us by our non-employee experts. The proportional performance method is used since reasonably dependable estimates of the revenues and costs applicable to various stages of a contract can be made, based on historical experience and terms set forth in the contract, and are indicative of the level of benefit provided to our clients. Fixed-price contracts generally convert to time-and-materials contracts in the event the contract terminates. Our management maintains contact with project managers to discuss the status of the projects and, for fixed-price engagements, management is updated on the budgeted costs and resources required to complete the project. These budgets are then used to calculate revenue recognition and to estimate the anticipated income or loss on the project. In the past, we have occasionally been required to commit unanticipated additional resources to complete projects, which has resulted in lower than anticipated income or losses on those contracts. We may experience similar situations in the future. Provisions for estimated losses on contracts are made during the period in which such losses become probable and can be reasonably estimated. To date, such losses have not been significant.

Revenues also include reimbursements, which include travel and other out-of-pocket expenses, outside consultants, and other reimbursable expenses. Reimbursable expenses are as follows (in thousands):

Our normal payment terms are 30 days from invoice date. For fiscal 2013, fiscal 2012, and fiscal 2011 our average days sales outstanding (DSOs) at the end of the period were 94 days, 98 days, and 96 days, respectively. We calculate DSOs by dividing the sum of our accounts receivable and unbilled services balance, net of deferred revenue, at the end of the period by average daily revenues. Average daily revenues are calculated by dividing period revenues by the number of days in the period. Our project managers and finance personnel monitor payments from our clients and assess any collection issues. We maintain accounts receivable allowances for estimated losses resulting from disputed amounts or the inability of our clients to make required payments. We base our estimates on our historical collection experience, current trends, and credit policy. In determining these estimates, we examine historical write-offs of our receivables and review client accounts to identify any specific customer collection issues. If the financial condition of our customers were to deteriorate or disputes were to arise regarding the services provided, resulting in an impairment of their ability or intent to make payment, additional allowances may be required. A failure to estimate accurately the accounts receivable allowances and ensure that payments are received on a timely basis could have a material adverse effect on our business, financial condition, and results of operations. As of December 28, 2013 and December 29, 2012, $7.2 million, and $9.5 million were provided for accounts receivable allowances, respectively.

Share-Based Compensation Expense. Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period of the award. We use the Black-Scholes option-pricing model to estimate the fair value of stock options.

Option valuation models require the input of assumptions, including the expected life of the share-based awards, the expected stock price volatility, the risk-free interest rate, and the expected dividend yield. The expected volatility and expected life are based on our historical experience. The risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected life of the share-based award. Expected dividend yield was not considered in the option pricing formula because we do not pay dividends and have no current plans to do so in the future. We will update these assumptions if changes are warranted. The forfeiture rate is based upon historical experience. We adjust the estimated forfeiture rate based upon our actual experience. In addition, we have performance-based awards that are valued at the fair value of shares as of the grant date and expense is recognized based on the number of shares expected to vest under the terms of the award under which they are granted. The fair value determination requires significant assumptions, including estimating future revenues and profits.

Valuation of Goodwill and Other Intangible Assets. We account for our acquisitions under the purchase method of accounting. Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired. Intangible assets typically consist of non-competition agreements, customer relationships, customer lists, developed technology, and trademarks, which are generally amortized on a straight-line basis over their estimated remaining useful lives (four to ten years).

In accordance with ASC Topic 350, "Intangibles—Goodwill and Other" ("ASC Topic 350"), goodwill and intangible assets with indefinite lives are not subject to amortization, but are monitored annually on October 15th for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. For our goodwill impairment analysis, we operate under one reporting unit.

Under ASC Topic 350, in performing the first step of the goodwill impairment testing and measurement process, we compare our entity-wide estimated fair value to net book value to identify potential impairment. We estimate the entity-wide fair value utilizing our market capitalization, plus an appropriate control premium. Market capitalization is determined by multiplying the shares outstanding on the test date by the market price of our common stock on that date. We have utilized a control premium which considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If our estimated fair value is less than our net book value, the second step is performed to determine if goodwill is impaired. If we determine through the impairment evaluation process that goodwill has been impaired, we would record the impairment charge in our consolidated statement of operations.

We had no impairment losses related to goodwill during fiscal 2013 as there were no events or circumstances that would more likely than not reduce our fair value below our carrying amount and our estimated fair value was greater than our carrying value on October 15, 2013.

Late in the second quarter of fiscal 2012, our stock price experienced a decline. In the third quarter of fiscal 2012, our stock price improved but remained below the price levels experienced in fiscal 2011 and the first five months of fiscal 2012. We did not record any impairment losses related to goodwill or intangible assets during the fiscal year to date period ended September 29, 2012 as the stock price decline was not deemed to be more than temporary, there were no other events or circumstances that would more likely than not reduce our fair value below our carrying amount, and our management felt that an increase in the stock price was a reasonable expectation. However, the depressed stock price levels persisted into the fourth quarter of 2012 and through the date of our annual impairment test performed in the fourth quarter fiscal 2012. When we performed our annual impairment test, our book value exceeded our market capitalization plus an estimated control premium. Therefore, we were required to perform the second step of the goodwill impairment test. In this step, our fair value, as determined in the first step of the test, is allocated among all of our assets and, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if we were being acquired in a business acquisition. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded for

the difference. During the process of conducting the second step of the annual goodwill impairment test in the fourth quarter of fiscal 2012, we identified significant unrecognized intangible assets. The combination of these hypothetical unrecognized intangible assets and other hypothetical unrecognized fair value changes to the carrying values of other assets and liabilities, together with the lower fair value calculated in the first step of the annual impairment test, resulted in a non-cash goodwill impairment charge of $71.4 million in the fourth quarter of fiscal 2012.

The re-measurement of goodwill is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed using our specific information. We used a combination of the income, cost and market approach techniques to determine the fair value of our assets and liabilities. The fair value adjustment to goodwill was computed as the difference between our fair value and the fair value of underlying assets and liabilities. The unobservable inputs used to determine the fair value of the underlying assets and liabilities were based on our specific information such as estimates of revenue and cost growth rates, profit margins, discount rates, and cost estimates.

In the future, if our market capitalization plus an estimated control premium is below our net book value for a period we consider to be other-than-temporary, we may be required to record an impairment of goodwill either as a result of our annual assessment performed in the fourth quarter of each fiscal year or in a future quarter if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. A goodwill impairment charge would have the effect of decreasing our earnings in such period. If we are required to take a substantial impairment charge, our operating results would be materially adversely affected in such period, though such a charge would have no impact on cash flows or working capital.

As of December 28, 2013, we had goodwill of approximately $81.6 million. The goodwill amount for acquisitions is initially recorded based upon a preliminary estimated purchase price allocation and is subject to change. Any preliminary purchase price allocation is based upon our estimate of fair value, and is finalized as we receive other information relevant to the acquisition.

We assess the impairment of amortizable intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include the following:

If we were to determine that an impairment evaluation is required, we would review the expected future undiscounted cash flows to be generated by the assets. If we determine that the carrying value of intangible assets may not be recoverable, we measure any impairment based on a projected discounted cash flow method using a discount rate determined by our management to be commensurate with the risk inherent in our current business model. The net amount of intangible assets was approximately $4.5 million as of December 28, 2013.

Accounting for Income Taxes. We record income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. 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.

Our financial statements contain certain deferred tax assets and liabilities that result from temporary differences between book and tax accounting, as well as net operating loss carryforwards. ASC Topic 740, "Income Taxes," ("ASC Topic 740") requires the establishment of a valuation allowance to reflect the likelihood of realization of deferred tax assets. Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, and any valuation allowance recorded against our net deferred tax assets. We evaluate the weight of all available evidence to determine whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The decision to record a valuation allowance requires varying degrees of judgment based upon the nature of the item giving rise to the deferred tax asset. As a result of operating losses incurred in certain of our foreign subsidiaries, and uncertainty as to the extent and timing of profitability in future periods, we recorded initial valuation allowances in fiscal 2013 and fiscal 2012 in these foreign subsidiaries based on the facts and circumstances affecting each subsidiary. Had we not recorded these allowances of approximately $0.4 million and $2.3 million, in fiscal 2013 and fiscal 2012, respectively, we would have reported a lower tax provision or a higher tax benefit, and a more favorable effective tax rate, than that recognized in our statements of operations in fiscal 2013 and fiscal 2012. If the realization of deferred tax assets is considered more likely than not, the corresponding release of the valuation allowance would increase net income in the period such determination was made. The amount of the deferred tax asset considered realizable is based on significant estimates, including forecasts of future income, and it is possible that changes in these estimates in the near term could materially affect our financial condition and results of operations.

Our effective tax rate may vary from period to period based on changes in estimated taxable income or loss, changes to the valuation allowance, changes to federal, state, or foreign tax laws, future expansion into areas with varying country, state, and local income tax rates, deductibility of certain costs, uncertain tax positions, and expenses by jurisdiction, and as a result of acquisitions or dispositions.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in several different tax jurisdictions. We are periodically reviewed by domestic and foreign tax authorities regarding the amount of taxes due. These reviews include questions regarding the timing and amount of deductions and the allocation of income among various tax jurisdictions. The Company accounts for uncertainties in income tax positions in accordance with ASC Topic 740. The number of years with open tax audits varies depending on the tax jurisdiction. Our major taxing jurisdiction is the United States. We are no longer subject to U.S. federal examinations by the Internal Revenue Service for years before fiscal 2012. Our United Kingdom subsidiary's corporate tax returns are no longer subject to examination by Her Majesty's Revenue and Customs for fiscal years before fiscal 2011. We believe our reserves for uncertain tax positions are adequate.

In July 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"), to clarify the presentation of current and deferred income taxes on the balance sheet. Under ASU 2013-11, companies generally must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, for an NOL carryforward, similar tax loss, or tax credit carryforward using the "net presentation" approach as a reduction of a deferred tax asset, with some allowed exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted and entities may choose to apply the amendments retrospectively to each prior reporting period presented. We believe the adoption of ASU 2013-11 will have no impact on our financial position, results of operations, cash flows, or disclosures.

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). ASU 2013-02 requires an entity disclose in a single location (either on the face of the financial statement that reports net income or in the notes) the effects of reclassifications out of accumulated other comprehensive income. For items reclassified out of accumulated other comprehensive income and into net income in their entirety, entities must disclose the effect of the reclassification on each affected net income item. For accumulated other comprehensive income reclassification items that are not reclassified in their entirety into net income, entities must provide a cross reference to other required U.S. GAAP disclosures. There is no change in the requirement to present the components of net income and other comprehensive income in either a single continuous statement or two separate consecutive statements. ASU 2013- 02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012 and should be applied prospectively. Our adoption of ASU 2013-02 in the first quarter of fiscal 2013 had no impact on our financial position, results of operations, cash flows, or disclosures.

In March 2013, the FASB issued ASU No. 2013-05, Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity ("ASU 2013-05"). ASU 2013-05 addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. ASU 2013-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied prospectively. Early adoption is permitted. We believe the adoption of ASU 2013-05 will have no impact on our financial position, results of operations, cash flows, or disclosures.

In July 2012, the FASB issued ASU No. 2012-02, Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment ("ASU 2012-02") to simplify the guidance for testing the decline in the realizable value (impairment) of indefinite-lived intangible assets other than goodwill. Under former guidance, an organization was required to test an indefinite-lived intangible asset for impairment on at least an annual basis by comparing the fair value of the asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeded its fair value, an impairment loss was recognized in an amount equal to the difference. ASU 2012-02 allows an organization the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. An organization electing to perform a qualitative assessment is no longer required to calculate the fair value of an indefinite-lived intangible asset unless the organization determines, based on a qualitative assessment, that it is "more likely than not" that the asset is impaired. ASU 2012-02 was effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Our adoption of ASU 2012-02 in fiscal 2013 had no impact on our financial position, results of operations, cash flows, or disclosures.

Revenues. Revenues increased by $8.0 million, or 3.0%, to $278.4 million for fiscal 2013 from $270.4 million for fiscal 2012 primarily due to increased revenue in our litigation, regulatory, and financial consulting business in the second half of fiscal 2013, reflecting organic growth and increasing contributions from the new senior-level hires we welcomed to CRA during the latter part of fiscal 2012 and the first quarter of fiscal 2013. The increase in revenue was partially offset by a decrease of revenue in our management consulting business in fiscal 2013 as compared to fiscal 2012. Although our management consulting business started fiscal 2013 slowly, it experienced improvements in project backlog toward the end of the second quarter of fiscal 2013 that continued into the second half of fiscal 2013. Our utilization increased to 73% for fiscal 2013 from 68% for the fiscal 2012. In addition, revenues were impacted by an increase in client reimbursable expenses, which are pass-through expenses that carry little to no margin, partially offset by a decrease in revenues of $0.4 million for NeuCo in fiscal 2013 as compared to fiscal 2012.

Overall, revenues outside of the U.S. represented approximately 22% of total revenues for fiscal 2013, compared with approximately 23% of total revenues for fiscal 2012. Revenues derived from fixed- price engagements decreased to 13% of total revenues for fiscal 2013 compared with 15% for fiscal 2012. This decrease was due primarily to the previously mentioned decrease in our management consulting business, as the management consulting business typically has a higher concentration of fixed-price service contracts.

Costs of Services. Costs of services increased by $6.9 million, or 3.8%, to $189.3 million for fiscal 2013 from $182.4 million for fiscal 2012. The increase in costs of services was due primarily to an increase in compensation expense, principally as a result of an increase in forgivable loan amortization

of $7.1 million. As is common in our industry, we have issued forgivable loans to attract and retain certain significant revenue-producing employees and non-employee experts. We issued $38.8 million and $20.7 million of forgivable loans in fiscal 2013 and fiscal 2012, respectively. Costs of services also had an increase of $3.8 million in client reimbursable expenses for fiscal 2013 as compared to fiscal 2012. The increases were offset by a decrease in cost of sales due to there being no restructuring expenses recorded in fiscal 2013 as compared to $3.8 million of expenses recorded in fiscal 2012 associated with the restructuring actions we announced in the third quarter of fiscal 2012.

As a percentage of revenues, costs of services increased to 68.0% for fiscal 2013 from 67.5% for fiscal 2012 due primarily to the increase in forgivable loan amortization and client reimbursable expenses as a percentage of revenues, partially offset by the decrease in in costs of services due to the $3.8 million of restructuring charges recorded during fiscal 2012 as compared with no restructuring charges in fiscal 2013.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $3.0 million, or 4.5%, to $64.2 million for fiscal 2013 from $67.2 million for fiscal 2012. Selling, general and administrative expenses in fiscal 2012 included $1.5 million of restructuring charges associated principally with the restructuring actions we announced in the third quarter of fiscal 2012, the reduction of leased office space in our London, England office and adjustments to our leased office space in Houston, TX and Chicago, IL. There were no restructuring charges recorded in selling, general and administrative expenses in fiscal 2013. Additionally contributing to this decrease were decreased rent and office operating expenses resulting from our reduction of leased office space in London, England and Boston, Massachusetts during fiscal 2012. Furthermore, decreases in outside consultant charges, travel expense, and professional fees for fiscal 2013 as compared to fiscal 2012 resulted from the restructuring actions we announced in the third quarter of fiscal 2012. Partially offsetting these decreases was an increase in commissions to non-employee experts of $2.3 million in fiscal 2013 as compared to fiscal 2012.

As a percentage of revenues, selling, general and administrative expenses decreased to 23.1% for fiscal 2013 from 24.9% for fiscal 2012, which was primarily due to restructuring charges recorded in fiscal 2012 and the decreased rent and office operating expenses, outside consultant charges, travel expenses, and professional fees in fiscal 2013 as compared with fiscal 2012, partially offset by the increase in commissions to non-employee experts from 2.3% of revenues for fiscal 2012 to 3.1% of revenues for fiscal 2013.

Depreciation and Amortization. Depreciation and amortization decreased by $0.8 million, or 10.8%, to $6.4 million for fiscal 2013 from $7.2 million for fiscal 2012. Of this decrease, approximately $1.1 million was related to the write-off of unamortized leaseholds and other costs associated with restructuring costs recorded in fiscal 2012 for the reduction of leased office space in our London, England office, as compared to there being no restructuring expenses recorded in fiscal 2013. The decrease was partially offset by the amortization of intangibles arising from the acquisition of a 40-person litigation consulting team that joined us effective February 1, 2013.

Goodwill Impairment. In accordance with ASC Topic 350, "Intangibles—Goodwill and Other", goodwill and intangible assets with indefinite lives are not subject to amortization, but are monitored annually for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. When we performed our annual impairment test in the fourth quarter of fiscal 2012, our net book value exceeded our market capitalization plus an estimated control premium. Therefore, we were required to perform the second step of the goodwill impairment test, which resulted in a goodwill impairment charge of $71.4 million. We recorded this non-cash goodwill impairment charge in the fourth quarter of fiscal 2012. We did not record any impairment charges in fiscal 2013.

Interest Expense. Interest expense increased by $0.3 million to $0.6 million for fiscal 2013 from $0.3 million for fiscal 2012. The increase was primarily due to interest expense related to the credit agreement we entered into on April 24, 2013 that provides us with a $125.0 million revolving credit

facility. Upon entering into the credit agreement, we borrowed $15.0 million under the revolving credit facility, which we used, together with cash on hand, to repay in full all indebtedness outstanding under the previous credit agreement, whereupon such agreement was terminated. During the second quarter of fiscal 2013, we borrowed an additional $2.3 million under the multi-currency portion of the credit agreement. We repaid $12.2 million during the second quarter of fiscal 2013 and the remaining $5.1 million during the third quarter of fiscal 2013.

Provision (Benefit) for Income Taxes. For fiscal 2013, our income tax provision was $6.7 million and the effective tax rate was 37.3% compared to an income tax benefit of $5.2 million and an effective tax rate of 8.9% for fiscal 2012. The effective tax rate for fiscal 2013 was lower than our combined federal and state statutory tax rate primarily due to the favorable settlement of a tax matter in the first quarter of fiscal 2013, partially offset by a discrete tax adjustment recorded in the second quarter of fiscal 2013 and the effect of losses in foreign jurisdictions that provided no tax benefit. The effective tax rate for fiscal 2012 was lower than the statutory rate primarily due to the $71.4 million goodwill impairment charge we recorded in the fourth quarter of fiscal 2012, a portion of which provided a tax benefit, partially offset by losses in foreign locations that provided no tax benefit and lower pre-tax income.

Net (Income) Loss Attributable to Noncontrolling Interest, Net of Tax. Our ownership interest in NeuCo was 55.89% at the end of fiscal 2013 and fiscal 2012 and constitutes control under U.S. GAAP. As a result, NeuCo's financial results are consolidated with ours and allocations of the noncontrolling interest's share of NeuCo's net income result in deductions to our net income, while allocations of the noncontrolling interest's share of NeuCo's net loss result in additions to our net income. NeuCo's results of operations allocable to its other owners was a net loss of $135,000 for fiscal 2013 and net income of $147,000 for fiscal 2012.

Net Income Attributable to CRA International, Inc. Net income attributable to CRA International, Inc. increased by $64.4 million to net income of $11.4 million for fiscal 2013 from a net loss of $53.0 million for fiscal 2012. The diluted net income per share was $1.12 per share for fiscal 2013, compared to net loss per share of $5.21 for fiscal 2012. Diluted weighted average shares outstanding increased by approximately 6,000 shares to approximately 10,173,000 shares for fiscal 2013 from approximately 10,167,000 shares for fiscal 2012. The increase in weighted average shares outstanding was primarily due to an increase as a result of shares of restricted stock that have vested or that have been issued, and stock options that have been exercised since December 29, 2012, partially offset by repurchases of common stock.

Revenues. Revenues decreased by $34.8 million, or 11.4%, to $270.4 million for fiscal 2012 from $305.2 million for fiscal 2011. Our fiscal 2012 results were negatively impacted by select underperforming practice areas, including our Chemicals practice and Middle East operations, which affected our overall performance compared to fiscal 2011. In connection with the restructuring plan we committed to in the third quarter of fiscal 2012, we eliminated our Chemicals practice, closed our Middle East operations and repositioned other select underperforming practice areas, amongst other actions. Utilization decreased to 68% for fiscal 2012 from 74% for fiscal 2011 reflecting this underperformance and these restructuring actions. Overall, revenues outside of the U.S. represented approximately 23% of total revenues for fiscal 2012, compared with approximately 26% of total revenues for the fiscal 2011. This decrease was due primarily to our management consulting business, particularly to our Chemicals practice and Middle East operations, which were eliminated in the third quarter of fiscal 2012, and our management consulting activity in Europe where economic uncertainties affected our performance, primarily during the earlier part of fiscal 2012. Revenues derived from fixed-price engagements decreased to 15% of total revenues for fiscal 2012 compared with 22% for fiscal 2011. This decrease was due primarily to the previously mentioned decrease in our management consulting business, as the management consulting business typically has a higher concentration of

fixed-price service contracts. Another factor contributing to our overall revenue decline was a decrease in client reimbursable expenses, which are pass-through expenses that carry little to no margin.

Costs of Services Costs of services decreased by $17.0 million, or 8.5%, to $182.4 million for fiscal 2012 from $199.4 million for fiscal 2011. As a result of our decreased revenues and profitability, we had a decrease in incentive bonus expense for our employee consultants in fiscal 2012 as compared to fiscal 2011. Additionally, client reimbursable expenses decreased by $6.2 million primarily due to a decrease in the use of outside consultants and subcontractors and a decrease in travel expenses as a result of the decreased revenue. Also contributing to the decrease in costs of services was a decrease in employee consultant headcount from 521 as of December 31, 2011 to 464 as of December 29, 2012 due to restructuring actions we announced in the third quarter of fiscal 2012. These decreases in costs of services were partially offset by $3.8 million of expenses in fiscal 2012 associated with the restructuring actions we announced in the third quarter of fiscal 2012, compared with no restructuring expenses recorded in costs of services in fiscal 2011.

As a percentage of revenues, costs of services increased to 67.5% for fiscal 2012 from 65.3% for fiscal 2011 primarily due to the decrease in revenues in fiscal 2012 compared with fiscal 2011, as the decrease in revenues outpaced the decrease in costs of services, and the $3.8 million of restructuring charges recorded during fiscal 2012 as compared with no restructuring charges recorded in costs of services in fiscal 2011. Partially offsetting these increases in costs of services as a percentage of revenues was the decrease in client reimbursable expenses as a percentage of revenues.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $4.5 million, or 6.3%, to $67.2 million for fiscal 2012 from $71.8 million for fiscal 2011. This decrease was due primarily to a decrease in compensation expense resulting from the decrease in headcount in fiscal 2012 as compared with fiscal 2011 and a decrease in incentive bonus expense for our employees as a result of the decrease in revenues and profitability in fiscal 2012 as compared with fiscal 2011. Additionally, NeuCo had a decrease in selling, general and administrative expenses of approximately $0.6 million in fiscal 2012 compared to fiscal 2011. Partially offsetting these decreases was an increase in commissions to nonemployee experts of $1.1 million in fiscal 2012 as compared to fiscal 2011 and a $0.5 million increase in restructuring expenses recorded in selling, general and administrative expenses to $1.5 million in fiscal 2012 as compared to $1.0 million of these restructuring expenses in fiscal 2011. These restructuring expenses in fiscal 2012 were associated principally with the restructuring actions we announced in the third quarter of fiscal 2012 and included the reduction of leased office space in our offices in London, England and in Boston, Massachusetts partially offset by adjustments to our leased office space in Houston, TX and Chicago, IL. These restructuring expenses in fiscal 2011 were related to leased office space in our Houston, TX office.

As a percentage of revenues, selling, general and administrative expenses increased to 24.9% for fiscal 2012 from 23.5% for the fiscal 2011, which was primarily a result of the decrease in revenues in fiscal 2012 compared with fiscal 2011 and the increase in restructuring costs of $0.5 million in fiscal 2012 as compared with fiscal 2011. Additionally, commissions to nonemployee experts increased from 1.7% of revenues for fiscal 2011 to 2.3% of revenues for fiscal 2012.

Depreciation and Amortization. Depreciation and amortization increased by $2.2 million, or 43.0%, to $7.2 million for fiscal 2012 from $5.0 million for fiscal 2011. Of this increase, approximately $1.1 million was related to the write-off of unamortized leaseholds and other costs associated with restructuring costs recorded in the second quarter of fiscal 2012 for the reduction of our leased office space in our London, England office and $0.2 million of similar charges recorded in the fourth quarter of fiscal 2012 for the reduction of our leased office space in our Boston, Massachusetts office. The remaining increase was primarily due to the amortization of software costs related to our implementation of an enterprise-wide financial reporting system at the start of fiscal 2012.

more likely than not reduce the fair value of the reporting unit below its carrying amount. When we performed our annual impairment test in the fourth quarter of fiscal 2012, our net book value exceeded our market capitalization plus an estimated control premium. Therefore, we were required to perform the second step of the goodwill impairment test, which resulted in a goodwill impairment charge of $71.4 million. We recorded this non-cash goodwill impairment charge in the fourth quarter of fiscal 2012.

Interest Expense. Interest expense decreased by $0.6 million to $0.3 million for fiscal 2012 from $0.9 million for fiscal 2011. The decrease was primarily due to our repurchase, on June 15, 2011, of 100% of the principal amount of our outstanding debentures and the accrued and unpaid interest thereon, which amounted to $21.9 million and $0.3 million, respectively. Through this final repurchase date, interest expense primarily consisted of interest incurred on this convertible debt, the amortization of debt issuance costs, and the amortization of the discount on the debt for the equity conversion feature of the debt instrument.

Other Expense, Net. Other expense, net decreased by $0.2 million to $0.2 million for fiscal 2012 from $0.4 million for fiscal 2011. Other expense, net consists primarily of foreign currency exchange transaction gains and losses. We continue to manage our foreign currency exchange exposure through frequent settling of intercompany account balances and by self-hedging movements in exchange rates between the value of the dollar and foreign currencies including the Euro and the British Pound.

(Provision) Benefit for Income Taxes. For fiscal 2012, our income tax benefit was $5.2 million and the effective tax rate was 8.9% compared to a provision of $11.1 million and an effective tax rate of 39.7% for fiscal 2011. The effective tax rate for fiscal 2012 was lower than the statutory rate primarily due to the $71.4 million goodwill impairment charge we recorded in the fourth quarter of fiscal 2012, a portion of which provided a tax benefit, partially offset by losses in foreign locations that provided no tax benefit and lower pre-tax income. The effective tax rate for fiscal 2011 benefited from the use of foreign net operating loss carryforwards and foreign tax credits that had not been previously benefited, and the related release of certain valuation allowances as a result of improved profitability in certain foreign jurisdictions.

Net (Income) Loss Attributable to Noncontrolling Interest, Net of Tax. Our ownership interest in NeuCo is 55.89% and constitutes control under U.S. GAAP. As a result, NeuCo's financial results are consolidated with ours and allocations of the noncontrolling interest's share of NeuCo's net income result in deductions to our net income, while allocations of the noncontrolling interest's share of NeuCo's net loss result in additions to our net income. NeuCo's results of operations allocable to its other owners was net income of $147,000 for fiscal 2012 and net income of $94,000 for fiscal 2011.

Net Income Attributable to CRA International, Inc. Net income attributable to CRA International, Inc. decreased by $69.8 million to a net loss of $53.0 million for fiscal 2012 from net income of $16.9 million for fiscal 2011. The net loss was $5.21 per share for fiscal 2012, compared to net income of $1.57 per diluted share for fiscal 2011. Diluted weighted average shares outstanding decreased by approximately 572,000 shares to approximately 10,167,000 shares for fiscal 2012 from approximately 10,739,000 shares for fiscal 2011. Diluted weighted average shares outstanding for fiscal 2012 excluded 140,000 common stock equivalents because we had a net loss and inclusion of these common stock equivalents would be anti-dilutive. The decrease in weighted average shares outstanding was primarily due to repurchases of common stock and lower average stock price in fiscal 2012 as compared to fiscal 2011, offset in part by an increase as a result of shares of restricted stock that have vested or that have been issued, and stock options that have been exercised since December 31, 2011.

We believe that current cash, cash equivalents, cash generated from operations, and amounts available under our bank line of credit will be sufficient to meet our anticipated working capital and capital expenditure requirements for at least the next 12 months.

General. In fiscal 2013, cash and cash equivalents decreased by $4.2 million. We completed the period with cash and cash equivalents of $51.3 million and working capital (defined as current assets less current liabilities) of $75.0 million. Of the total cash and cash equivalents of $51.3 million at December 28, 2013, $41.8 million was in the U.S. We have sufficient sources of cash in the U.S. to fund U.S. cash requirements without the need to repatriate any funds.

As of December 28, 2013, a substantial portion of our cash accounts was concentrated at a single financial institution, which potentially exposes us to credit risks. The financial institution has a short-term credit rating of A-2 by Standard & Poor's ratings services. We have not experienced any losses related to such accounts and we do not believe that there is significant risk of non-performance by the financial institution. Our cash on deposit at this financial institution is fully liquid, and we continually monitor the credit ratings of this institution. A change in the credit worthiness of this financial institution could materially affect our liquidity and working capital.

Sources and Uses of Cash. During fiscal 2013, net cash provided by operations was $18.4 million. The primary factor in cash provided by operations was the increase in "accounts payable, accrued expenses, and other liabilities" of $11.1 million, which includes approximately $40.0 million for accrued fiscal 2013 performance bonuses, partially offset by the payment of approximately $28 million for the majority of our fiscal 2012 performance bonuses during fiscal 2013. We anticipate that a majority of the accrued performance bonuses for fiscal 2013 will be paid during the the first quarter of fiscal 2014. Other sources of cash included a $7.7 million net favorable movement in "accounts receivable" and "accounts receivable allowances" due primarily to significant cash collections on accounts receivable balances during the fourth quarter of fiscal 2013, offset partially by a decrease in "unbilled services" of $3.0 million. These sources of cash were offset by a decrease in "prepaid expenses and other current assets, and other assets" of $20.2 million during fiscal 2013 due primarily to our payment of approximately $38.8 million in forgivable loans and advances to employees and non-employee experts and other decreases of $4.8 million, offset partially by $14.2 million of forgivable loan amortization in fiscal 2013 and movements of approximately $9.3 million in income taxes receivable and deferred tax assets. Cash provided by operations also included net income of $11.2 million, non-cash charges for depreciation and amortization expense of $6.5 million, deferred income tax provision of $3.9 million, and share-based compensation expense of $3.0 million, partially offset by decreased deferred rent of $1.9 million.

During fiscal 2013, net cash used in investing activities was $18.4 million, which included $15.6 million of net acquisition consideration payments and $2.8 million for capital expenditures.

Net cash used in financing activities during fiscal 2013 was $4.5 million. On April 24, 2013, we entered into a credit agreement and borrowed $15.0 million under the revolving credit facility, which we used, together with cash on hand, to repay in full all indebtedness outstanding under the previous credit agreement, whereupon such agreement was terminated. During fiscal 2013, we borrowed an additional $2.3 million under the multi-currency portion of the credit agreement. No borrowings were outstanding at the end of fiscal 2013, as we repaid the entire balance during fiscal 2013. We paid debt issuance costs of approximately $1.1 million in connection with entering into the credit agreement. Additionally, NeuCo paid in full a note payable of $0.7 million during the third quarter of fiscal 2013. Additional cash used in financing activities included the repurchase of stock of $2.2 million and the redemption of $0.7 million in vested employee restricted shares for tax withholdings, partially offset by $0.2 million received upon the exercise of stock options.

On April 24, 2013, we entered into a credit agreement that provides us with a $125.0 million revolving credit facility and a $15 million sublimit for the issuance of letters of credit. We may use the proceeds of the revolving credit loans to provide working capital and for other general corporate purposes. Generally, we may repay any borrowings under the revolving credit facility at any time, but must repay all borrowings no later than April 24, 2018. Upon entering into the agreement, we borrowed $15.0 million under the revolving credit facility, which we used, together with cash on hand,

to repay in full all indebtedness outstanding under the previous credit agreement, whereupon such agreement was terminated. We also borrowed an additional $2.3 million during the second quarter of fiscal 2013 under the multicurrency portion of the credit agreement. There were no amounts outstanding under this revolving line of credit as of December 28, 2013, as we repaid $17.3 million during fiscal 2013.

Additionally, letters of credit in the aggregate amount of approximately $0.4 million that had been issued under the previous credit agreement were deemed to be issued and outstanding under the new revolving credit facility. The amount available under this revolving line of credit is reduced by certain letters of credit outstanding, which amounted to $0.4 million as of December 28, 2013.

Borrowings under the revolving credit facility bear interest at a rate per annum of either (i) the adjusted base rate, as defined in the credit agreement, plus an applicable margin, which varies between 0.50% and 1.50% depending on our total leverage ratio as determined under the credit agreement, or (ii) the adjusted eurocurrency rate, as defined in the credit agreement, plus an applicable margin, which varies between 1.50% and 2.50% depending on our total leverage ratio. We are required to pay a fee on the unused portion of the revolving credit facility at a rate per annum that varies between 0.25% and 0.375% depending on our total leverage ratio. Borrowings under the credit facility are secured by 100% of the stock of certain of our U.S. subsidiaries and 65% of the stock of certain of our foreign subsidiaries, which represent approximately $6.5 million in net assets as of December 28, 2013.

Under the credit agreement, we must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including our failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require us to maintain a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, our ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations.

In order to attract and retain highly skilled professionals, we may issue forgivable loans or term loans to employees and non-employee experts. The forgivable loans have terms that are generally between three and eight years. The principal amount of forgivable loans and accrued interest is forgiven by us over the term of the loans, so long as the employee or non-employee expert continues employment or affiliation with us and complies with certain contractual requirements. The expense associated with the forgiveness of the principal amount of the loans is recorded as compensation expense over the service period, which is consistent with the term of the loans. During fiscal 2013, we issued approximately $38.8 million in forgivable loans to employees and non-employee experts for future service. As of December 28, 2013, we had obligations to issue approximately $5.0 million in forgivable loans to future employees for future service. The $5.0 million in loans were issued, and the corresponding payments were made, in the first quarter of fiscal 2014.

In connection with an acquisition completed in fiscal 2013, we agreed to pay incentive performance awards to certain non-employee experts and employees of the acquired business, if specific performance targets are met from June 2013 through May 2017. Retention of amounts paid is contingent on their continued relationships with us through May 2019. The amount of the award could fluctuate depending on future performance through May 2017. Changes in the estimated award are expensed prospectively over the remaining service period. We believe that we will have sufficient funds to satisfy any obligations related to the incentive performance awards. We expect to fund these payments, if any, from existing cash resources, cash generated from operations, or financing transactions.

On January 31, 2013, we announced that an approximate 40-person litigation consulting team had joined us, effective February 1, 2013. Under an agreement to hire the team, we accelerated the previously announced start dates of certain key personnel from May 2013. Under the terms of the transaction, we acquired certain intangible assets, accounts receivable, and certain client projects currently underway. The fair value of the assets acquired and the liabilities assumed as part of the acquisition will be finalized as we receive other information relevant to the acquisition and complete our analysis of other transaction-related costs. The acquisition was not material. The acquisition has been accounted for under the purchase method of accounting, and the results of operations have been included in the accompanying statements of operations from the date of acquisition.

As part of our business, we regularly evaluate opportunities to acquire other consulting firms, practices or groups or other businesses. In recent years, we have typically paid for acquisitions with cash, or a combination of cash and our common stock, and we may continue to do so in the future. To pay for an acquisition, we may use cash on hand, cash generated from our operations, borrowings under our revolving credit facility, or we may pursue other forms of financing. Our ability to secure short-term and long-term debt or equity financing in the future, including our ability to refinance our current senior loan agreement, will depend on several factors, including our future profitability, the levels of our debt and equity, restrictions under our existing revolving line of credit with our bank, and the overall credit and equity market environments.

On August 30, 2011, we announced that our Board of Directors approved a share repurchase program of up to $7.5 million of our common stock. On February 22, 2012 and August 10, 2012, our Board of Directors authorized the repurchase of up to an additional $4.45 million and $5.0 million, respectively, of our common stock under these programs. During fiscal 2013, we repurchased and retired 118,968 shares under these programs at an average price per share of $18.44. As of December 28, 2013, $1.4 million was available for future repurchases under these programs. On February 13, 2014, we announced that our Board of Directors approved a share repurchase program of up to an additional $15.0 million of our common stock.

We will finance these programs with available cash and cash from future operations. We may repurchase shares in open market purchases or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. We expect to continue to repurchase shares under these programs.

To date, inflation has not had a material impact on our financial results. There can be no assurance, however, that inflation will not adversely affect our financial results in the future.

The following table presents information about our known contractual obligations as of December 28, 2013. It does not reflect contractual obligations that may have arisen or may arise after that date. Except for historical facts, the information in this section is forward-looking information.

On February 24, 2014, we entered into a new lease with BP Hancock LLC, as landlord, for the 9th and 10th floors (a total of 57,602 square feet) of the same office building at 200 Clarendon Street, Boston, Massachusetts in which our Boston offices are currently located. The lease's base term will expire ten years from the date that we begin paying fixed rent under the lease and, subject to certain conditions, will be extendible by us for two five-year periods. The annual fixed rent for this office space (which does not include customary operating costs and expenses) will be $42 per square foot, or $2.4 million, for the first year of the lease's base term and will increase at the rate of $1.00 per square foot during the remainder of the lease's base term. The lease gives us a right of first refusal to rent certain additional office space in the office building if it becomes available. The performance of our obligations under the lease is secured by a $1 million letter of credit.

We are party to standby letters of credit with RBS Citizens N.A. in support of the minimum future lease payments under leases for permanent office space and bonds required per the terms of certain project proposals and contracts amounting to $0.4 million as of December 28, 2013.

Item 1A of this annual report sets forth risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this annual report. If any of these risks, or any risks not presently known to us or that we currently believe are not significant, develops into an actual event, then our business, financial condition, and results of operations could be adversely affected.

The majority of our operations are based in the U.S. and, accordingly, the majority of our transactions are denominated in U.S. Dollars. However, we have foreign-based operations where transactions are denominated in foreign currencies and are subject to market risk with respect to fluctuations in the relative value of foreign currencies. Our primary foreign currency exposures relate to our short-term intercompany balances with our foreign subsidiaries and accounts receivable and cash valued in the United Kingdom in U.S. Dollars or Euros. Our primary foreign subsidiaries have functional currencies denominated in the British Pound and Euro, and foreign denominated assets and liabilities are remeasured each reporting period with any exchange gains and losses recorded in our consolidated statements of operations. We continue to manage our foreign currency exchange exposure through frequent settling of intercompany account balances and by self-hedging movements in exchange rates between the value of the U.S. Dollar and foreign currencies and the Euro and the British Pound. Holding all other variables constant, fluctuations in foreign exchange rates may affect reported revenues and expenses, based on our currency exposures at December 28, 2013. A hypothetical 10% movement in foreign exchange rates on December 28, 2013 would have affected our income before provision for income taxes for the fourth quarter of fiscal 2013 by approximately $0.2 million. However, actual gains and losses in the future could differ materially from this analysis based on the timing and amount of both foreign currency exchange rate movements and our actual exposure.

From time to time, we may use derivative instruments to manage the risk of exchange rate fluctuations. However, at December 28, 2013, we had no outstanding derivative instruments. We do not use derivative instruments for trading or speculative purposes.

We maintain an investment portfolio consisting mainly of commercial paper and money market funds with maturities of three months or less when purchased. These held-to-maturity securities are subject to interest rate risk. However, a hypothetical change in the interest rate of 10% would not have a material impact to the fair values of these securities at December 28, 2013 primarily due to their short maturity.

We have included our consolidated financial statements in this annual report starting on page FS-1. We have provided an index to our consolidated financial statements on page FS-1.

Item 9—Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. This is done in order to ensure that information the Company is required to disclose in reports that are filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of December 28, 2013, because of a material weakness, described below in Management's Report on Internal Control over Financial Reporting.

Notwithstanding the material weakness discussed below, management has concluded that the consolidated financial statements included in this form 10-K present fairly, in all material aspects, the Company's financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States.

Except for the material weakness in internal control over financial reporting related to the accounting and reporting for income taxes, we have determined that, during the fourth quarter of fiscal 2013, there were no changes in our internal control over financial reporting that have affected, or are reasonably likely to affect, materially our internal control over financial reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we assessed the effectiveness of our internal control over financial reporting as of the end of the period covered by this report based on the framework in "Internal Control—Integrated Framework (1992)" issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on that assessment, our President and Chief Executive Officer and our Chief Financial Officer concluded that our internal control over financial reporting was not effective to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. generally accepted accounting principles as of December 28, 2013 because of a material weakness in internal control described in the second succeeding paragraph.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis.

The Company's controls were not sufficiently complete and comprehensive to ensure that our income tax accounting and reporting for income taxes were complete and accurate. Specifically, there was inadequate detailed documentation maintained and ineffective analysis and review of the documentation supporting the Company's income tax accounts. Although the amount of tax related misstatements corrected in the Company's consolidated financial statements were immaterial, the absence of sufficient controls creates a reasonable possibility that a material misstatement in the Company's annual or interim consolidated financial statements would not be prevented or detected in a timely manner.

Our independent registered public accounting firm, KPMG LLP, has issued an audit report on their assessment of our internal control over financial reporting. The audit report is included herein.

Management has initiated a remediation plan which includes the following actions:

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, there can be no assurance that any system of disclosure controls and procedures or internal control over financial reporting will be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.

We have audited CRA International, Inc.'s internal control over financial reporting as of December 28, 2013, based on criteria established in "Internal Control – Integrated Framework (1992)" issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). CRA International, 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, included in the accompanying Management's Report on Internal Control Over Financial Reporting (Item 9A(c)). Our responsibility is to express an opinion on 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, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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 deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. A material weakness related to the accounting and reporting for income taxes has been identified and included in management's assessment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CRA International, Inc. and subsidiaries as of December 28, 2013 and December 29, 2012, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and shareholders' equity for each of the fiscal years ended December 28, 2013, December 29, 2012, and December 31, 2011. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2013 consolidated financial statements, and this report does not affect our report dated March 13, 2014, which expressed an unqualified opinion on those consolidated financial statements.

In our opinion, because of the effect of the aforementioned material weakness on the achievement of the objectives of the control criteria, CRA International, Inc. has not maintained effective internal

control over financial reporting as of December 28, 2013, based on criteria established in "Internal Control – Integrated Framework (1992)" issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We have omitted the information required in Part III of this annual report because we intend to include that information in our definitive proxy statement for the 2014 special meeting in lieu of annual meeting of shareholders, which we expect to file before 120 days after the end of fiscal 2013.

	101**	The following financial statements from CRA International, Inc.'s Annual Report on Form 10-K for the fiscal year ended December 28, 2013, formatted in XBRL (eXtensible Business Reporting Language), as follows: (i) Consolidated Statements of Operations for the fiscal years ended December 28, 2013, December 29, 2012 and December 31, 2011, (ii) Consolidated Statements of Comprehensive Income (Loss) for the fiscal years ended December 28, 2013, December 29, 2012 and December 31, 2011, (iii) Consolidated Balance Sheets as at December 28, 2013 and December 29, 2012, (iv) Consolidated Statements of Cash Flows for the fiscal years ended December 28, 2013, December 29, 2012 and December 31, 2011, (v) Consolidated Statements of Shareholders' Equity for the fiscal years ended December 28, 2013, December 29, 2012 and December 31, 2011, and (vi) Notes to Consolidated Financial Statements.

We have audited the accompanying consolidated balance sheets of CRA International, Inc. and subsidiaries as of December 28, 2013 and December 29, 2012, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and shareholders' equity for each of the fiscal years ended December 28, 2013, December 29, 2012, and December 31, 2011. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements 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 CRA International, Inc. and subsidiaries as of December 28, 2013 and December 29, 2012, and the results of their operations and their cash flows for the fiscal years ended December 28, 2013, December 29, 2012, and December 31, 2011, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), CRA International, Inc.'s internal control over financial reporting as of December 28, 2013, based on criteria established in "Internal Control—Integrated Framework (1992)" issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 13, 2014 expressed an adverse opinion on the effectiveness of the Company's internal control over financial reporting.

CRA International, Inc. ("CRA") is a worldwide leading consulting services firm that applies advanced analytic techniques and in-depth industry knowledge to complex engagements for a broad range of clients. CRA offers services in two broad areas: litigation, regulatory, and financial consulting and management consulting. CRA operates in one business segment, which is consulting services. CRA operates its business under its registered trade name, Charles River Associates.

CRA's fiscal year end is the Saturday nearest December 31 of each year. CRA's fiscal years periodically contain 53 weeks rather than 52 weeks. Fiscal 2013, fiscal 2012, and fiscal 2011 were 52-week years.

The consolidated financial statements include the accounts of CRA and its wholly owned subsidiaries. In addition, as more fully explained below, the consolidated financial statements include CRA's interest in NeuCo, Inc. ("NeuCo"). All significant intercompany accounts have been eliminated.

CRA's ownership interest in NeuCo is 55.89%. CRA's ownership interest has constituted control under GAAP for all periods presented. Therefore, NeuCo's financial results have been consolidated with CRA's and the portion of NeuCo's results allocable to its other owners is shown as "noncontrolling interest." NeuCo's revenues included in the CRA's consolidated statements of operations for fiscal 2013, fiscal 2012, and fiscal 2011 totaled approximately $5.1 million, $5.5 million, and $6.2 million, respectively. NeuCo's net loss included in CRA's consolidated statements of operations for fiscal 2013 was approximately $0.3 million. NeuCo's net income included in CRA's consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.3 million and $0.2 million, respectively. NeuCo's net loss, net of amounts allocable to its other owners, included in CRA's consolidated statements of operations for fiscal 2013 was approximately $0.2 million. NeuCo's net income, net of amounts allocable to its other owners, included in CRA's consolidated statements of operations for fiscal 2012 and fiscal 2011 was approximately $0.2 million and $0.1 million, respectively. NeuCo's interim reporting schedule is based on calendar month-ends, and its fiscal year end is the last Saturday of November. CRA's quarterly results could include a few days reporting lag between CRA's quarter end and the most recent financial statements available from NeuCo. CRA does not believe that the reporting lag, if any, will have a significant impact on CRA's consolidated statements of operations or financial condition.

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of consolidated revenues and expenses during the reporting period. Estimates in these consolidated financial statements include, but are not limited to, accounts and unbilled receivable allowances, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long lived assets and goodwill, accrued and deferred income taxes, valuation allowances

on deferred tax assets, accrued compensation, accrued exit costs, and other accrued expenses. These items are monitored and analyzed by CRA for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. CRA bases its estimates on historical experience and various other assumptions that CRA believes to be reasonable under the circumstances. Actual results may differ from those estimates if CRA's assumptions based on past experience or other assumptions do not turn out to be substantially accurate.

CRA derives substantially all of its revenues from the performance of professional services. The contracts that CRA enters into and operates under specify whether the engagement will be billed on a time-and-materials or a fixed-price basis. These engagements generally last three to six months, although some of CRA's engagements can be much longer in duration. Each contract must be approved by one of CRA's vice presidents.

CRA recognizes substantially all of its revenues under written service contracts with its clients when the fee is fixed or determinable, as the services are provided, and only in those situations where collection from the client is reasonably assured and sufficient contractual documentation has been obtained. In certain cases CRA provides services to its clients without sufficient contractual documentation, or fees are tied to performance-based criteria, which require CRA to defer revenue in accordance with U.S. GAAP. In these cases, these amounts are fully reserved until all criteria for recognizing revenue are met.

CRA's revenues include projects secured by our non-employee experts as well as projects secured by our employees. CRA recognizes all project revenue on a gross basis based on the consideration of the criteria set forth in Accounting Standards Codification ("ASC") Topic 605-45, Principal Agent Considerations.

Most of CRA's revenue is derived from time-and-materials service contracts. Revenues from time-and-materials service contracts are recognized as services are provided based upon hours worked and contractually agreed-upon hourly rates, as well as indirect fees based upon hours worked.

Revenues from the majority of CRA's fixed-price engagements are recognized on a proportional performance method based on the ratio of costs incurred, substantially all of which are labor-related, to the total estimated project costs. CRA derived approximately 13%, 15%, and 22% of consolidated revenues from fixed-price engagements in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. In general, project costs are classified as costs of services and are based on the direct salary of the consultants on the engagement plus all direct expenses incurred to complete the engagement, including any amounts billed to us by our non-employee experts. The proportional performance method is used because reasonably dependable estimates of the revenues and costs applicable to various stages of a contract can be made, based on historical experience and the terms set forth in the contract, and are indicative of the level of benefit provided to CRA's clients. Fixed-price contracts generally convert to time-and-materials contracts in the event the contract terminates. CRA's management maintains contact with project managers to discuss the status of the projects and, for fixed-price engagements, management is updated on the budgeted costs and resources required to complete the project. These budgets are then used to calculate revenue recognition and to estimate the anticipated income or loss on the project. Occasionally, CRA has been required to commit unanticipated additional resources to complete projects, which has resulted in lower than anticipated income or losses on those contracts. CRA may experience similar situations in the future. Provisions for estimated losses on contracts are made during the period in which such losses become probable and can be reasonably estimated. To date, such losses have not been significant.

Revenues also include reimbursable expenses, which include travel and other out-of-pocket expenses, outside consultants, and other reimbursable expenses. Reimbursable expenses are as follows (in thousands):

CRA maintains accounts receivable allowances for estimated losses and disputed amounts resulting from clients' failure to make required payments. CRA bases its estimates on historical collection experience, current trends, and credit policy. In determining these estimates, CRA examines historical write-offs of its receivables and reviews client accounts to identify any specific customer collection issues. If the financial condition of CRA's customers were to deteriorate or disputes were to arise regarding the services provided, resulting in an impairment of their ability or intent to make payment, additional allowances may be required.

Unbilled services represent revenue recognized by CRA for services performed but not yet billed to the client. Deferred revenue represents amounts billed or collected in advance of services rendered.

CRA collects goods and services and value added taxes from customers and records these amounts on a net basis, which is within the scope of ASC Topic 605-45, Principal Agent Considerations.

Cash equivalents consist principally of money market funds and commercial paper with maturities of three months or less when purchased. As of December 28, 2013, a substantial portion of CRA's cash accounts was concentrated at a single financial institution, which potentially exposes CRA to credit risks. The financial institution has a short-term credit rating of A-2 by Standard & Poor's ratings services. CRA has not experienced any losses related to such accounts. CRA does not believe that there is significant risk of non-performance by the financial institution and the cash on deposit is fully liquid. CRA continually monitors the credit ratings of the institution.

The carrying amounts of these instruments classified as cash equivalents are stated at amortized cost, which approximates fair value because of their short-term maturity.

CRA's financial instruments, including cash, cash equivalents, accounts receivable, loans and advances from employees and non-employee experts, accounts payable, and accrued expenses, are carried at cost, which approximates their fair value because of the short-term maturity of these instruments or because their stated interest rates are indicative of market interest rates.

In accordance with ASC Topic 350, "Intangibles—Goodwill and Other", goodwill is not subject to amortization, but is monitored at least annually for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. For the CRA's goodwill impairment analysis, CRA operates under one reporting unit. Under ASC Topic 350, in performing the first step of the goodwill impairment testing and measurement process, CRA compares its entity-wide estimated fair value to net book value to identify potential impairment. Management estimates the entity-wide fair value utilizing CRA's market capitalization, plus an appropriate control premium. Market capitalization is determined by multiplying

the shares outstanding on the test date by the market price of CRA's common stock on that date. CRA has utilized a control premium which considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If the fair value of CRA is less than its net book value, the second step is performed to determine if goodwill is impaired. If CRA determines through the impairment evaluation process that goodwill has been impaired, an impairment charge would be recorded in the consolidated statement of operations.

There were no impairment losses related to goodwill during fiscal 2013 as there were no events or circumstances that would more likely than not reduce CRA's fair value below its carrying amount.

When CRA performed its annual impairment test in the fourth quarter of fiscal 2012, its net book value exceeded its market capitalization plus an estimated control premium. Therefore, CRA was required to perform the second step of the goodwill impairment test. In this step, CRA's fair value is allocated among all of its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if CRA were being acquired in a business acquisition. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded for the difference. During the process of conducting the second step of the annual goodwill impairment test in the fourth quarter of fiscal 2012, CRA identified significant unrecognized intangible assets. The combination of these hypothetical unrecognized intangible assets and other hypothetical unrecognized fair value changes to the carrying values of other assets and liabilities, together with the lower fair value calculated in the first step of the annual impairment test, resulted in a goodwill impairment charge of $71.4 million in the fourth quarter of fiscal 2012.

The re-measurement of goodwill is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed using CRA-specific information. CRA used a combination of the income, cost and market approach techniques to determine the fair value of its assets and liabilities. The fair value adjustment to goodwill was computed as the difference between CRA's fair value and the fair value of underlying assets and liabilities. The unobservable inputs used to determine the fair value of the underlying assets and liabilities were based on CRA-specific information such as estimates of revenue and cost growth rates, profit margins, discount rates, and cost estimates.

Intangible assets that are separable from goodwill and have determinable useful lives are valued separately and amortized over their estimated useful lives. Intangible assets consist of non-competition agreements, customer relationships, customer lists, developed technology, and trademarks, all of which are generally amortized on a straight-line basis over their remaining useful lives of four to ten years.

Property and equipment are recorded at cost. Depreciation is calculated using the straight-line method based on the estimated useful lives of three years for computer equipment, three to ten years for computer software, and ten years for furniture and fixtures. Amortization of leasehold improvements is calculated using the straight-line method over the shorter of the lease term or the estimated useful life of the leasehold improvements. Expenditures for maintenance and repairs are expensed as incurred. Expenditures for renewals and betterments are capitalized.

CRA leases all of its office space. Leases are evaluated and classified as operating or capital leases for financial reporting purposes. For leases that contain rent escalations and rent holidays, CRA records the total rent payable during the lease term, as determined above, on a straight-line basis over

the term of the lease and records the difference between the rents paid and the straight-line rent as deferred rent. Additionally, any tenant improvement allowances received from the lessor are recorded as a reduction to deferred rent.

CRA reviews the carrying value of its long-lived assets (primarily property and equipment and intangible assets) to assess the recoverability of these assets whenever events or circumstances indicate that impairment may have occurred. Factors CRA considers important that could trigger an impairment review include the following:

If CRA determines that an impairment review is required, CRA would review the expected future undiscounted cash flows to be generated by the assets or asset groups. If CRA determines that the carrying value of long-lived assets or asset groups may not be recoverable, CRA would measure any impairment based on a projected discounted cash flow method using a discount rate determined by CRA to be commensurate with the risk inherent in CRA's current business model. If impairment is indicated through this review, the carrying amount of the assets would be reduced to their estimated fair value.

CRA's billed and unbilled receivables consist of receivables from a broad range of clients in a variety of industries located throughout the U.S. and in other countries. CRA performs a credit evaluation of its clients to minimize its collectability risk. Periodically, CRA will require advance payment from certain clients. However, CRA does not require collateral or other security. CRA maintains accounts receivable allowances for estimated losses and disputed amounts resulting from clients' failures to make required payments. CRA bases its estimates on historical collection experience, current trends, and credit policy. In determining these estimates, CRA examines historical write-offs of its receivables and reviews client accounts to identify any specific customer collection issues. If the financial condition of any of CRA's customers were to deteriorate, resulting in an impairment of their ability or intent to make payment, additional allowances may be required.

A rollforward of the accounts receivable allowances is as follows (in thousands):

CRA accounts for equity-based compensation using a fair value based recognition method. Under the fair value recognition requirements of ASC Topic 718, "Compensation-Stock Compensation" ("ASC Topic 718"), share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date.

For share-based awards granted to non-employee experts, CRA accounts for the compensation under variable accounting in accordance with ASC Topic 718 and ASC Topic 505-50, "Equity-Based Payments to Non-Employees" (formerly Emerging Issues Task Force 96-18, "Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services"), and recognizes the cost over the related vesting period. For performance-vesting restricted stock units awarded to employees, CRA accounts for the compensation under variable accounting in accordance with ASC Topic 718, and recognizes the cost over the related vesting period.

CRA accounts for income taxes using the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. 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. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

In addition, the calculation of CRA's tax liabilities involves dealing with uncertainties in the application of complex tax regulations in several different tax jurisdictions. CRA records liabilities for estimated tax obligations resulting in a provision for taxes that may become payable in the future, in accordance with ASC Topic 740-10, "Income Taxes," which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, and disclosure. CRA includes accrued interest and penalties, if any, related to uncertain tax positions in income tax expense.

Balance sheet accounts of CRA's foreign subsidiaries are translated into U.S. dollars at year-end exchange rates and operating accounts are translated at average exchange rates for each year. The resulting translation adjustments are recorded in shareholders' equity as a component of accumulated other comprehensive income (loss). Foreign currency transactions are translated at current exchanges rates, with adjustments recorded in the statement of operations. The effect of transaction gains and losses recorded in income (loss) before (provision) benefit for income taxes amounted to losses of $0.2 million, $0.2 million, and $0.4 million for fiscal 2013, fiscal 2012, and fiscal 2011, respectively.

In July 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11") to clarify the presentation of current and deferred income taxes on the balance sheet. Under ASU 2013-11, companies generally must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, for an NOL carryforward, similar tax loss, or tax credit carryforward using the "net presentation" approach as a reduction of a deferred tax asset, with some allowed exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted and entities may choose to apply the amendments retrospectively to each prior reporting period presented. CRA believes the adoption of ASU 2013-11 will have no impact on its financial position, results of operations, cash flows, or disclosures.

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). ASU 2013-02 requires an entity disclose in a single location (either on the face of the financial statement that reports net income or in the notes) the effects of reclassifications out of accumulated other comprehensive income. For items reclassified out of accumulated other comprehensive income and into net income in their entirety, entities must disclose the effect of the reclassification on each affected net income item. For accumulated other comprehensive income reclassification items that are not reclassified in their entirety into net income, entities must provide a cross reference to other required U.S. GAAP disclosures. There is no change in the requirement to present the components of net income and other comprehensive income in either a single continuous statement or two separate consecutive statements. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012 and should be applied prospectively. CRA's adoption of ASU 2013-02 in the first quarter of fiscal 2013 had no impact on its financial position, results of operations, cash flows, or disclosures.

In March 2013, the FASB issued ASU No. 2013-05, Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity ("ASU 2013-05"). ASU 2013-05 addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. ASU 2013-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied prospectively. Early adoption is permitted. CRA believes the adoption of ASU 2013-05 will have no impact on its financial position, results of operations, cash flows, or disclosures.

carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeded its fair value, an impairment loss was recognized in an amount equal to the difference. ASU 2012-02 allows an organization the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. An organization electing to perform a qualitative assessment is no longer required to calculate the fair value of an indefinite-lived intangible asset unless the organization determines, based on a qualitative assessment, that it is "more likely than not" that the asset is impaired. ASU 2012-02 was effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. CRA's adoption of ASU 2012-02 in fiscal 2013 had no impact on its financial position, results of operations, cash flows, or disclosures.

On January 31, 2013, CRA announced that an approximately 40-person litigation consulting team joined CRA, effective February 1, 2013. Under an agreement to hire the team, CRA accelerated the previously announced start dates of certain key personnel from May 2013. Under the terms of the transaction, CRA acquired certain intangible assets, accounts receivable, and certain client projects currently underway. The fair values of the assets acquired and the liabilities assumed as part of the acquisition will be finalized as CRA receives other information relevant to the acquisition and completes its analysis of other transaction-related costs. The acquisition was not material. The acquisition has been accounted for under the purchase method of accounting, and the results of operations have been included in the accompanying statements of operations from the date of acquisition.

Prepaid expenses and other current assets consist of the following (in thousands):

In order to attract and retain highly skilled professionals, CRA may issue forgivable loans or term loans to employees and non-employee experts which are classified in "prepaid expenses and other current assets" and "other assets" on the accompanying balance sheets as of December 28, 2013 and December 29, 2012. The forgivable loans have terms that are generally between three and eight years. The principal amount of forgivable loans and accrued interest is forgiven by CRA over the term of the loans, so long as the employee or non-employee expert continues employment or affiliation with CRA and complies with certain contractual requirements. The expense associated with the forgiveness of the principal amount of the loans is recorded as compensation expense over the service period, which is consistent with the term of the loans. During fiscal 2013 and fiscal 2012, CRA issued approximately $38.8 million and $20.7 million, respectively, in forgivable loans to employees and non-employee experts

for future service. As of December 28, 2013, CRA had obligations to issue approximately $5.0 million in forgivable loans to future employees for future service, which are included in the $51.1 million of such loans reported as of December 28, 2013 in the table above. The $5.0 million in loans were issued, and the corresponding payments were made, in the first quarter of fiscal 2014.

The changes in the carrying amount of goodwill for fiscal 2013 and fiscal 2012 are as follows (in thousands):

There were no impairment losses related to goodwill during fiscal 2013. When CRA performed its annual impairment test in the fourth quarter of fiscal 2012, its net book value exceeded its market capitalization plus an estimated control premium. Therefore, CRA was required to perform the second step of the goodwill impairment test, which resulted in a goodwill impairment charge of $71.4 million. CRA recorded this goodwill impairment charge in the fourth quarter of fiscal 2012.

Intangible assets that are separable from goodwill and have determinable useful lives are valued separately and amortized over their expected useful lives. There were no impairment losses related to intangible assets during fiscal 2013, fiscal 2012, or fiscal 2011.

The components of acquired identifiable intangible assets are as follows (in thousands):

Amortization of intangible assets was $1.2 million, $0.8 million, and $0.9 million in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. Amortization of intangible assets held at December 28, 2013 for the next five fiscal years is expected to be as follows (in thousands):

Depreciation expense, including amounts recorded in costs of services, was $5.2 million, $5.0 million, and $4.1 million, in fiscal 2013, fiscal 2012, and fiscal 2011, respectively.

As of December 28, 2013 and December 29, 2012, approximately $40 million and $28 million of accrued bonuses for fiscal 2013 and fiscal 2012, respectively, were included above in "Compensation and related expenses". Additionally, as of December 28, 2013, CRA had obligations to issue approximately $5.0 million in forgivable loans to future employees for future service, which are included in "Other" in the table above. The $5.0 million in loans were issued, and the corresponding payments were made, in the first quarter of fiscal 2014.

On April 24, 2013, CRA entered into a credit agreement that provides CRA with a $125.0 million revolving credit facility and a $15 million sublimit for the issuance of letters of credit. CRA may use the proceeds of the revolving credit loans for working capital and other general corporate purposes. CRA may repay any borrowings under the revolving credit facility at any time, but no later than April 24, 2018. Upon entering into the agreement, CRA borrowed $15.0 million under the revolving credit facility, which it used, together with cash on hand, to repay in full all indebtedness outstanding under CRA's previous credit agreement, whereupon such agreement was terminated. CRA also borrowed an additional $2.3 million during the second quarter of fiscal 2013 under the multi-currency portion of the credit agreement. There was no amount outstanding under this revolving line of credit as of December 28, 2013, as CRA repaid these borrowings before the end of the third quarter of fiscal 2013.

As of December 28, 2013, the amount available under this revolving line of credit was reduced by certain letters of credit outstanding, which amounted to $0.4 million. Borrowings under the revolving credit facility bear interest at a rate per annum of either (i) the adjusted base rate, as defined in the credit agreement, plus an applicable margin, which varies between 0.50% and 1.50% depending on CRA's total leverage ratio as determined under the credit agreement, or (ii) the adjusted eurocurrency rate, as defined in the credit agreement, plus an applicable margin, which varies between 1.50% and 2.50% depending on CRA's total leverage ratio. CRA is required to pay a fee on the unused portion of the revolving credit facility at a rate per annum that varies between 0.25% and 0.375% depending on its total leverage ratio. Borrowings under the credit facility are secured by 100% of the stock of certain of CRA's U.S. subsidiaries and 65% of the stock of certain of its foreign subsidiaries, which represent approximately $6.5 million in net assets as of December 28, 2013.

Under the credit agreement, CRA must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including CRA's failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require CRA to maintain a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, CRA's ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations.

CRA maintains qualified defined-contribution plans under Section 401(k) of the Internal Revenue Code, covering substantially all U.S. employees who meet specified age and service requirements. Company contributions are made at the discretion of CRA, and cannot exceed the maximum amount deductible under applicable provisions of the Internal Revenue Code. Company contributions under these plans amounted to approximately $1.7 million, $1.8 million, and $2.7 million for fiscal 2013, fiscal 2012, and fiscal 2011, respectively.

At December 28, 2013, CRA had the following minimum rental commitments for office space and equipment leases, all of which are under non-cancelable operating leases (in thousands):

Certain office leases contain renewal options that CRA may exercise at its discretion, which were not included in the amounts above. Rent expense was approximately $9.6 million in fiscal 2013, $12.4 million in fiscal 2012, and $13.6 million in fiscal 2011. Included in rent expense were $0.9 million and $1.0 million in restructuring charges in fiscal 2012 and fiscal 2011, respectively. There were no restructuring charges during fiscal 2013.

CRA is party to standby letters of credit with its bank in support of the minimum future lease payments under leases for office space amounting to $0.4 million as of December 28, 2013.

Basic net income (loss) per share represents net income (loss) divided by the weighted average shares of common stock outstanding during the period. Diluted net income per share represents net income divided by the weighted average shares of common stock and common stock equivalents, if applicable, outstanding during the period. Common stock equivalents arise from stock options and unvested shares of restricted stock, using the treasury stock method. Under the treasury stock method, the amount CRA would receive on the exercise of stock options and the vesting of shares of restricted stock, the amount of compensation cost for future service that CRA has not yet recognized, and the amount of tax benefits that would be recorded in common stock when these stock options and shares of restricted stock become deductible are assumed to be used to repurchase shares at the average share price over the applicable fiscal period, and these repurchased shares are netted against the shares underlying these stock options and these unvested shares of restricted stock. A reconciliation of basic to diluted weighted average shares of common stock outstanding is as follows (in thousands):

For fiscal 2013, fiscal 2012, and fiscal 2011, certain share-based awards, which amounted to 1,138,411, 1,947,992, and 1,045,351 shares, respectively, were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares outstanding because they were anti-dilutive. These share-based awards were anti-dilutive because their exercise price exceeded the average market price over the applicable period. Additionally, approximately 140,000 common stock equivalents were excluded from diluted weighted average shares outstanding for fiscal 2012 because they were anti-dilutive as CRA had a net loss for that period.

Share-Based Compensation. Approximately $2.9 million, $4.9 million, and $5.7 million of share-based compensation expense was recorded in fiscal 2013, fiscal 2012, and fiscal 2011, respectively, as an increase to common stock for share-based payment awards made to CRA's employees and directors, based on the estimated grant date fair values of stock options and shares of restricted stock vesting during the period.

CRA also recorded $147,000, $79,000, and $34,000 for fiscal 2013, fiscal 2012, and fiscal 2011, respectively, in shared-based compensation expense for grants to non-employee experts.

Restricted Share Vesting. In fiscal 2013, fiscal 2012, and fiscal 2011, 134,384, 216,528, and 164,086 shares of restricted stock vested, respectively. CRA redeemed 37,642, 69,207, and 50,724 of these shares from their holders in order to pay $0.7 million, $1.4 million, and $1.1 million, respectively, of employee tax withholdings.

Common Stock Repurchases and Retirements. On July 6, 2010, CRA announced that its Board of Directors approved a share repurchase program of up to $5 million of CRA's common stock. On August 30, 2011, February 22, 2012 and August 10, 2012, the Board of Directors authorized the repurchase of up to an additional $7.5 million, $4.45 million, and $5.0 million, respectively, of CRA's common stock under these programs.

During fiscal 2013, CRA repurchased and retired 118,968 shares of its common stock under these programs at an aggregate price of approximately $2.2 million, resulting in approximately $1.4 million available for future repurchases as of December 28, 2013. During fiscal 2012, CRA repurchased and retired 466,109 shares of its common stock under these programs at an aggregate price of approximately $9.1 million. During fiscal 2011, CRA repurchased and retired 398,372 shares of its common stock under these programs at an aggregate price of approximately $9.1 million. CRA records the retirement of its repurchased common stock as a reduction to common stock.

On February 13, 2014, CRA announced that its Board of Directors approved a share repurchase program of up to an additional $15.0 million of CRA's common stock.

During fiscal 2013, fiscal 2012, and fiscal 2011, CRA did not repurchase any shares of its common stock from non-employee experts and employees based on contractual rights of first purchase contained in their stock purchase agreement with CRA.

Exercise of Stock Options. During fiscal 2013, 13,389 options were exercised for $0.2 million of proceeds. During fiscal 2012, 47,185 options were exercised for $0.6 million of proceeds. During fiscal 2011, 47,009 options were exercised for $0.6 million of proceeds.

Tax Deficit on Stock Option Exercises and Restricted Share Vesting. CRA recorded tax deficits on stock options exercises and vesting of shares of restricted stock as a decrease to common stock in fiscal 2013, fiscal 2012, and fiscal 2011, totaling $0.3 million, $0.6 million, and $0.6 million, respectively.

CRA recorded $2.9 million, $4.9 million, and $5.7 million of compensation expense for fiscal 2013, fiscal 2012, and fiscal 2011, respectively, for share-based awards consisting of stock options, shares of restricted stock and time-vesting restricted stock units issued to employees and directors based on their respective estimated grant date fair values. Compensation expense also includes performance-vesting restricted stock units issued to employees that are accounted for under variable accounting in accordance with ASC Topic 718.

Compensation expense, net of tax, was $1.9 million, $3.0 million, and $3.5 million in fiscal 2013, fiscal 2012, and fiscal 2011, respectively, for share-based awards made to CRA's employees and directors consisting of stock options, shares of restricted stock, and time-vesting restricted stock units issued to employees and directors based on their respective estimated grant date fair values and for performance-vesting restricted stock units issued to employees that are accounted for under variable accounting.

In addition, CRA recorded $87,000, $47,000, and $20,000 of share-based compensation expense, net of tax, during fiscal 2013, fiscal 2012, and fiscal 2011, respectively, for share-based awards consisting of stock options and shares of restricted stock issued to non-employees (other than directors).

The weighted average fair market value using the Black-Scholes option-pricing model of the stock options granted in fiscal 2013, and fiscal 2011 was $7.77 and $10.01, respectively. There were no stock options granted during fiscal 2012. The fair market value of the stock options at the date of grant was estimated using the Black-Scholes option-pricing model with the following weighted average assumptions:

The risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected life of the stock options. Expected volatility and expected life are based on CRA's historical experience. Expected dividend yield was not considered in the option-pricing formula because CRA does not pay dividends and has no current plans to do so in the future. The forfeiture rate used was based upon historical experience. CRA may adjust the estimated forfeiture rate based upon actual experience.

CRA maintains share-based compensation plans that use restricted stock, stock options, restricted stock units, as well as an employee stock purchase plan, to provide incentives to its directors, employees and independent contractors.

CRA's Amended and Restated 2006 Equity Incentive Plan, as amended (the "2006 Incentive Plan"), authorizes the grant of a variety of incentive and performance awards to CRA's directors, employees and independent contractors, including incentive stock options, nonqualified stock options, restricted stock awards, restricted stock unit awards, performance awards and other share-based awards. Each share of CRA's common stock issued pursuant to an award (other than a stock option) granted under the 2006 Incentive Plan on or after April 30, 2010 counts as 1.83 shares against the maximum number of shares issuable under the plan, as does any restricted stock unit or other performance award granted under the plan on or after April 30, 2010 to the extent that shares of CRA's common stock were or will be used for measurement purposes. This "fungibility ratio" with respect to shares of CRA's common stock issued pursuant to awards (other than stock options) granted under the plan, as well as

restricted stock unit and other performance awards granted under the plan to the extent that shares of CRA's common stock are used for measurement purposes, was 2.2 for grants made on or after March 12, 2008 and before April 30, 2010 and 1.8 for grants made before March 12, 2008. The maximum number of shares issuable under the 2006 Incentive Plan is 4,874,000, consisting of (1) 500,000 shares initially reserved for issuance under the 2006 Incentive Plan, (2) 1,000,000 shares that either remained for future awards under our 1998 Incentive and Nonqualified Stock Option Plan (the "1998 Plan") on April 21, 2006, the date CRA's shareholders initially approved the 2006 Incentive Plan, or were subject to stock options issued under the 1998 Plan that were forfeited or terminated after April 21, 2006, (3) 210,000 shares approved by CRA's shareholders in 2008, (4) 1,464,000 shares approved by CRA's shareholders in 2010, and (5) the 1,700,000 shares that CRA has determined to use of the 2,500,000 shares approved by CRA's shareholders in 2012.

During fiscal 2009, CRA implemented a long-term incentive program ("LTIP") for certain key employees. Under this program, participants may receive a mixture of stock options, restricted stock units, and performance-vesting restricted stock units. The program is designed to reward key employees and provide participants the opportunity to share in the long-term growth of CRA. CRA has granted options, restricted stock units, and performance-vesting restricted stock units under this program during fiscal 2009 through fiscal 2013, except fiscal 2012. The awards were granted under the 2006 Incentive Plan and are included in the discussion below. The following is a rollforward of the maximum number of shares issuable under the 2006 Incentive Plan as of December 28, 2013:



Maximum shares of common stock issuable under the 2006 Incentive Plan		4,874,000
Restricted shares or units granted/reserved through March 12, 2008	471,827	(849,289	)
Restricted shares or units granted/reserved from March 12, 2008 to April 29, 2010	352,932	(776,450	)
Restricted shares or units granted/reserved on or after April 30, 2010	1,196,776	(2,190,100	)
Cancellation of restricted shares or units through March 12, 2008	91,277	164,299
Cancellation of restricted shares or units from March 12, 2008 to April 29, 2010	91,964	202,321

Options cancelled		183,208
Options forfeited		10,000


Shares available for grant under the 2006 Incentive Plan		1,255,216

Under the 1998 Plan, 3,839,216 options to purchase shares have been granted. With the adoption of the 2006 Incentive Plan, no new options will be granted under the 1998 Plan. Under the terms of the 1998 Plan, options have been granted at an exercise price equal to the fair market value of the shares of common stock at the date of grant. Vesting terms were determined at the discretion of the Board of Directors and generally range from immediate vesting to vesting at various rates up to five years. In general, stock options terminate 7 to 10 years after the date of grant.

In addition, under CRA's 2004 Nonqualified Inducement Stock Option Plan, options to purchase 359,420 shares have been granted. With the adoption of the 2006 Incentive Plan, no new stock options will be granted under the 2004 Nonqualified Inducement Stock Option Plan.

Under CRA's 2009 Nonqualified Inducement Stock Option Plan, options to purchase 200,000 shares have been granted. There are a maximum of 250,000 shares available for issuance pursuant to stock option grants under the 2009 Nonqualified Inducement Stock Option Plan. There are an additional 50,000 stock options available for grant under this plan. Each stock option vests over four years, has a term of seven years, and an exercise price equal to $50.00 per share.

The aggregate intrinsic value of stock options exercised in fiscal 2013, fiscal 2012, and fiscal 2011 was approximately $0.1 million, $0.4 million, and $0.6 million, respectively. The following table summarizes stock options outstanding and stock options exercisable as of December 28, 2013:

	Options Outstanding						Options Exercisable

Range of Exercise Prices	Number Outstanding at December 28, 2013		Weighted-Average Remaining Contractual Life (years)		Weighted-Average Exercise Price		Number Exercisable at December 28, 2013		Weighted-Average Exercise Price

The following table summarizes the status of CRA's non-vested stock options since December 29, 2012:

The total fair value of stock options that vested during fiscal 2013, fiscal 2012, and fiscal 2011 was $1.3 million, $1.5 million, and $1.1 million, respectively. As of December 28, 2013, there was $3.0 million of total unrecognized compensation cost, net of expected forfeitures, related to non-vested stock options granted. That cost is expected to be recognized over a weighted-average period of 2.9 years.

CRA grants restricted stock and time-vesting restricted stock unit awards, which are subject to the execution of a restricted stock agreement or restricted stock unit agreement, as applicable. Generally, shares of restricted stock and time-vesting restricted stock units vest in four equal annual installments beginning on the first anniversary of the date of grant. Total unrecognized compensation cost, net of expected forfeitures, related to restricted stock and time-vesting restricted stock unit awards as of December 28, 2013 was $4.7 million, which is expected to be recognized over a weighted-average period of 2.8 years.

The following table summarizes the status of CRA's non-vested restricted stock and time-vesting restricted stock unit awards since December 29, 2012:

As of December 28, 2013, there were 175,277 vested shares outstanding that include a right of first refusal provision in favor of CRA. As of December 28, 2013, there were 236,062 stock options exercisable that include this right of first refusal provision.

Performance share awards are valued based on the fair value of CRA's stock as of the grant date and expense is recognized based on the number of shares expected to vest under the terms of the award under which they are granted. As of December 28, 2013, up to approximately 219,000 shares will become issuable under performance share awards upon achievement of certain financial performance goals, including revenue and profits, for a measurement period falling within the first quarter of fiscal 2014 through the fourth quarter of fiscal 2015.

CRA adopted its 1998 Employee Stock Purchase Plan. The Stock Purchase Plan authorizes the issuance of up to an aggregate of 243,000 shares of common stock to participating employees at a purchase price equal to 85% of fair market value on either the first or the last day of the one-year offering period under the Stock Purchase Plan. In fiscal 2013, fiscal 2012, and fiscal 2011, there were no offering periods under the Stock Purchase Plan and no shares were issued.

In general, a valuation allowance is recorded against deferred tax assets because CRA's management believes, after considering the available evidence, that it is more likely than not that the assets will not be realized. Reductions in valuation allowances are a result of management's consideration of historical profitability, future expected results and the nature of the related deferred tax assets. The net change in the total valuation allowance for fiscal 2013 was a decrease of approximately $1.2 million compared to fiscal 2012. The $1.2 million decrease was related to the recording of a $1.4 million increase to a deferred tax liability in fiscal 2013 associated with goodwill and a corresponding decrease to valuation allowance and to the utilization of $0.6 million of certain prior net operating losses, offset partially by additional valuation allowances recorded against certain net deferred assets including foreign net operating losses of $0.4 million and NeuCo net operating losses of $0.4 million. The net change in the total valuation allowance for fiscal 2012 was an increase of approximately $2.3 million compared to fiscal 2011. The net change was related to the recording of additional valuation allowances against certain foreign net deferred assets including foreign net operating losses of $2.5 million reduced by the utilization of $0.2 million of certain prior net operating losses. The ultimate realization of deferred tax assets that continue to be subject to valuation allowances is dependent upon the generation of future taxable income during the periods and in the tax jurisdictions in which those temporary differences become deductible.

At December 28, 2013 CRA had $11.8 million of foreign net operating loss carry forwards and $0.4 million in U.S. state net operating loss carryforwards. NeuCo has net operating loss carryforwards for U.S. federal and U.S. state tax purposes of $6.1 million which are subject to a full valuation allowance and begin to expire in 2021. NeuCo files a separate U.S. federal tax return and none of its losses are available to offset CRA's consolidated taxable income. The foreign operating losses have an indefinite life, except for $0.2 million that will begin to expire in 2016.

The aggregate changes in the balances of gross unrecognized tax benefits were as follows (in thousands):

CRA files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. A number of years may elapse before an uncertain tax position, for which CRA has unrecognized tax benefits, is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, CRA believes that its unrecognized tax benefits reflect the most likely outcome. CRA adjusts these unrecognized tax benefits, and the associated interest, in light of changing facts and circumstances. At the end of fiscal 2013, CRA had $67,000 of interest on its unrecognized tax benefit balance. CRA reports accrued interest and penalties related to unrecognized tax benefits in income tax expense. Settlement of any particular position could require the use of cash. Of the total $372,000 balance at the end of fiscal 2013, a favorable resolution would result in $47,000 being recognized as a reduction to the effective income tax rate in the period of resolution. It is reasonably likely that $47,000 of unrecognized tax benefits will reverse within the next twelve months.

The number of years with open tax audits varies depending on the tax jurisdiction. CRA's major taxing jurisdiction is the United States. CRA is no longer subject to U.S. federal examinations by the Internal Revenue Service for years before fiscal 2012. CRA's United Kingdom subsidiary's corporate tax returns are no longer subject to examination by Her Majesty's Revenue and Customs for fiscal years before fiscal 2011. CRA believes its reserves for uncertain tax positions are adequate.

CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings from its foreign subsidiaries of approximately $3.2 million as of December 28, 2013 because such earnings are considered to be indefinitely reinvested. CRA does not rely on these unremitted earnings as a source of funds for its domestic business as it expects to have sufficient cash flow in the U.S. to fund its U.S. operational and strategic needs. If CRA were to repatriate its foreign earnings that are indefinitely reinvested, it would accrue substantially no additional tax expense.

CRA made payments to shareholders of CRA who performed consulting services exclusively for CRA in the amounts of $6.1 million, $5.4 million, and $7.3 million in fiscal 2013, fiscal 2012, and fiscal 2011, respectively. These payments were to exclusive non-employee experts for consulting services performed for CRA's clients in the ordinary course of business.

During fiscal 2012, CRA incurred pre-tax restructuring expenses of $6.7 million, of which approximately $5.4 million was for termination benefits, facility-related charges, asset write-downs and other charges in connection with the plan committed to by CRA's management during the third quarter of fiscal 2012 to eliminate and restructure selected practice areas and reduce selling, general and administrative costs. In connection with this plan, CRA eliminated its Chemicals practice and closed its

Middle East operations. These restructuring actions, along with the repositioning of other select underperforming practice areas, resulted in the reduction of more than 60 consulting positions. Commensurate with these consulting staff reductions, CRA also took significant actions to lower its selling, general and administrative costs by reducing CRA's administrative staff, eliminating excess office space capacity, better rationalizing remaining office space, and lowering administrative spending, particularly related to outside contractors and professional fees. These restructuring actions were designed to intensify the focus of CRA's portfolio, increase the cohesiveness of its services and improve its margins and profitability. The majority of these actions occurred during the third quarter of fiscal 2012, and the remainder was completed during the fourth quarter of fiscal 2012.

Additionally, during fiscal 2012, CRA entered into an agreement with the landlord of its London, England office to surrender the lease of one of the three floors it leased in the office building in London. Under this agreement, CRA surrendered its lease of this floor on June 30, 2012, instead of on the lease's original termination date of October 2, 2016, and paid the landlord approximately $1.2 million in connection with the surrender. In connection with this surrender, CRA incurred pre-tax restructuring charges of $1.7 million, which included the $1.2 million surrender charge and approximately $0.5 million of fixed asset write-offs and other charges or offsets. During fiscal 2012, CRA also recorded pre-tax restructuring credits of approximately $0.4 million related primarily to adjustments to its leased office space in Houston, TX and Chicago, IL.Of the $6.7 million of restructuring charges recorded during fiscal 2012, approximately $3.8 million was charged to cost of sales, $1.5 million was charged to selling, general and administrative expenses, and $1.4 million was charged to depreciation and amortization expense.

The restructuring expenses and reserve balance are as follows as of December 28, 2013 and December 29, 2012 (in thousands):

Earnings per share is calculated for each period, and the sum of the four quarters may not equal the full year amount.

In connection with an acquisition completed in fiscal 2013, CRA agreed to pay incentive performance awards to certain non-employee experts and employees of the acquired business, if specific performance targets are met from June 2013 through May 2017. Retention of amounts paid is contingent on their continued relationships with CRA through May 2019. The amount of the award could fluctuate depending on future performance through May 2017. Changes in the estimated award are expensed prospectively over the remaining service period.

On February 24, 2014, CRA entered into a new lease with BP Hancock LLC, as landlord, for the 9th and 10th floors (a total of 57,602 square feet) of the same office building at 200 Clarendon Street, Boston, Massachusetts in which CRA's Boston offices are currently located. The lease's base term will expire ten years from the date that CRA begins paying fixed rent under the lease and, subject to certain conditions, will be extendible by CRA for two five-year periods. The annual fixed rent for this office space (which does not include customary operating costs and expenses) will be $42 per square foot, or $2.4 million, for the first year of the lease's base term and will increase at the rate of $1.00 per square foot during the remainder of the lease's base term. The lease gives CRA a right of first refusal to rent certain additional office space in the office building if it becomes available. The performance of our obligations under the lease is secured by a $1 million letter of credit.

Concurrently with our entering into this new lease, CRA also entered into an amendment of its existing lease with BP Hancock LLC, as landlord, for the office space it currently rents in the office building described above, which currently expires on March 31, 2015. Except with respect to 25,099 square feet of office space covered by this lease, the amendment either extends the term of this lease to, or if prior to March 31, 2015 terminates this lease on, the day prior to the date that CRA begins paying fixed rent under the new lease described above. If the term of the existing lease is extended, the amendment provides that the base rent payable under this lease during the extension period will be $2.4 million per year.

CRA currently expects that the term of the new lease will commence, and the relocation of its Boston offices to the 9th and 10th floors of the office building at 200 Clarendon Street, Boston, Massachusetts will occur, sometime in the second quarter of fiscal 2015.
