Part I

When we use the terms “Lazard”, “we”, “us”, “our”, and “the Company”, we mean Lazard Ltd, a company incorporated under the laws of Bermuda, and its subsidiaries, including Lazard Group LLC, a Delaware limited liability company (“Lazard Group”), that is the current holding company for our businesses. Lazard Ltd has no material operating assets other than indirect ownership as of December 31, 2011 of approximately 94.8% of the common membership interests in Lazard Group and its controlling interest in Lazard Group.

Item 1. Business

Lazard is a preeminent financial advisory and asset management firm. We have long specialized in crafting solutions to the complex financial and strategic challenges of a diverse set of clients around the world, including corporations, governments, institutions, partnerships and individuals. Founded in 1848 in New Orleans, we currently operate from 42 cities in key business and financial centers across 27 countries throughout Europe, North America, Asia, Australia, the Middle East and Central and South America.

Principal Business Lines

We focus primarily on two business segments - Financial Advisory and Asset Management. We believe that the mix of our activities across business segments, geographic regions, industries and investment strategies helps to diversify and stabilize our revenue stream.

Financial Advisory

Lazard is a leading global independent advisor to corporations, governments, sovereigns, institutions and individual clients. We offer a wide array of financial advisory services regarding mergers and acquisitions (“M&A”) and other strategic matters, restructurings, capital structure, capital raising and various other financial matters. We focus on solving our clients’ most complex problems, providing advice to key decision-makers, senior management, boards of directors and business owners, as well as governments and governmental agencies, in transactions that typically are of significant strategic and financial importance to them.

We continue to build our Financial Advisory business by fostering long-term, senior level relationships with existing and new clients as their independent advisor on strategic transactions. We seek to build and sustain long-term relationships with our clients rather than focusing simply on individual transactions, a practice that we believe enhances our access to senior management of major corporations and institutions around the world. We emphasize providing clients with senior level focus during all phases of transaction execution.

While we strive to earn repeat business from our clients, we operate in a highly competitive environment in which there are no long-term contracted sources of revenue. Each revenue-generating engagement is separately negotiated and awarded. To develop new client relationships, and to develop new engagements from historical client relationships, we maintain an active dialogue with a large number of clients and potential clients, as well as with their financial and legal advisors, on an ongoing basis. We have gained a significant number of new clients each year through our business development initiatives, through recruiting additional senior investment banking professionals who bring with them client relationships and through referrals from directors, attorneys and other third parties with whom we have relationships. At the same time, we lose clients each year as a result of the sale or merger of a client, a change in a client’s senior management, competition from other investment banks and other causes.

For the years ended December 31, 2011, 2010 and 2009, the Financial Advisory segment net revenue totaled $992 million, $1.120 billion and $987 million, respectively, accounting for approximately 54%, 59% and 65%, respectively, of our consolidated net revenue for such years. We earned $1 million or more from 241 clients, 255 clients and 257 clients for the years ended December 31, 2011, 2010 and 2009, respectively. For the years

1

ended December 31, 2011, 2010 and 2009, the ten largest fee paying clients constituted approximately 14%, 16% and 17% of our Financial Advisory segment net revenue, respectively, with no client individually having constituted more than 10% of segment net revenue during any of these years. For the years ended December 31, 2011, 2010 and 2009, the Financial Advisory segment reported operating income (loss) of $62 million, $169 million and $(12) million, respectively. Operating income in 2010 and 2009 included charges of approximately $20 million and $49 million, respectively, representing the portion of special items (as described in Management’s Discussion and Analysis of Financial Condition and Results of Operations) that are applicable to the Financial Advisory segment. Excluding the impact of such special items, our Financial Advisory segment had operating income of $189 million and $37 million in the years ended December 31, 2010 and 2009, respectively. At December 31, 2011, 2010 and 2009, the Financial Advisory segment had total assets of $768 million, $799 million and $707 million, respectively.

We believe that we have been pioneers in offering financial advisory services on an international basis, with the establishment of our New York, Paris and London offices dating back to the nineteenth century. We maintain a major local presence in the U.S., the United Kingdom (the “U.K.”) and France, including a network of regional branch offices in the U.S. and France, as well a presence in Argentina, Australia, Belgium, Brazil, Chile, China, Colombia, Germany, India, Italy, Japan, the Netherlands, Panama, Peru, Saudi Arabia, Singapore, South Korea, Spain, Sweden, Switzerland, the United Arab Emirates and Uruguay.

Over the past several years, our Financial Advisory segment has made several business acquisitions and entered into certain other business relationships. In 2007 we acquired all of the outstanding ownership interests of Goldsmith, Agio, Helms & Lynner, LLC (“GAHL”), a Minneapolis-based investment bank specializing in financial advisory services to mid-sized private companies, all of the outstanding shares of Carnegie, Wylie & Company (Holdings) PTY LTD (“CWC”), an Australia-based financial advisory and private equity firm, now known as Lazard Holdings Pty Limited, and, along with the Company’s existing financial advisory business in Australia, referred to below as “Lazard Australia”, and concurrently sold such investment to Lazard Group, and we entered into a joint cooperation agreement with Raiffeisen Investment AG (“Raiffeisen”) for merger and acquisition advisory services in Russia and the Central and Eastern European (the “CEE”) region. The cooperation between us and Raiffeisen, one of the CEE region’s top M&A advisors, provides domestic, international and cross-border expertise within Russia and the CEE region. In 2008, we acquired a 50% interest in Merchant Bankers Asociados (“MBA”), an Argentina-based financial advisory services firm with offices across Central and South America and the parent company of MBA Banco de Inversiones. In 2009, we entered into a strategic alliance with a financial advisory firm in Mexico to provide global M&A advisory services for clients, both inside and outside of Mexico, who are seeking to acquire or sell assets in Mexico or have interests in other financial transactions with companies in Mexico, and to provide restructuring advisory services to clients in Mexico.

In addition to seeking business centered in the locations referred to above, we historically have focused in particular on advising clients with respect to cross-border transactions. We believe that we are particularly well known for our legacy of offering broad teams of professionals who are indigenous to their respective regions and who have long-term client relationships, capabilities and know-how in their respective regions, who will coordinate with our professionals with global sector expertise. We also believe that this positioning affords us insight around the globe into key industry, economic, government and regulatory issues and developments, which we can bring to bear on behalf of our clients.

Services Offered

We advise clients on a wide range of strategic and financial issues. When we advise clients on the potential acquisition of another company, business or certain assets, our services include evaluating potential acquisition targets, providing valuation analyses, evaluating and proposing financial and strategic alternatives and rendering, if appropriate, fairness opinions. We also may advise as to the timing, structure, financing and pricing of a proposed acquisition and assist in negotiating and closing the acquisition. In addition, we may assist in executing an acquisition by acting as a dealer-manager in transactions structured as a tender or exchange offer.

2

When we advise clients that are contemplating the sale of certain businesses, assets or their entire company, our services include advising on the appropriate sales process for the situation, valuation issues, assisting in preparing an offering circular or other appropriate sales materials and rendering, if appropriate, fairness opinions. We also identify and contact selected qualified acquirors and assist in negotiating and closing the proposed sale. As appropriate, we also advise our clients regarding financial and strategic alternatives to a sale including recapitalizations, spin-offs, carve-outs and split-offs. Our advice includes recommendations with respect to the structure, timing and pricing of these alternatives.

For companies in financial distress, our services may include reviewing and analyzing the business, operations, properties, financial condition and prospects of the company, evaluating debt capacity, assisting in the determination of an appropriate capital structure and evaluating and recommending financial and strategic alternatives, including providing advice on dividend policy. If appropriate, we may provide financial advice and assistance in developing and seeking approval of a restructuring or reorganization plan, which may include a plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code or other similar court administered processes in non-U.S. jurisdictions. In such cases, we may assist in certain aspects of the implementation of such a plan, including advising and assisting in structuring and effecting the financial aspects of a sale or recapitalization, structuring new securities, exchange offers, other consideration or other inducements to be offered or issued, as well as assisting and participating in negotiations with affected entities or groups.

When we assist clients in connection with their capital structure, we typically review and analyze structural alternatives, assist in long-term capital planning and advise and assist with respect to rating agency discussions and relationships, among other things.

When we assist clients in raising private or public market financing, our services include originating and executing private placements of equity, debt and related securities, assisting clients in connection with securing, refinancing or restructuring bank loans, originating public underwritings of equity, debt and convertible securities and originating and executing private placements of partnership and similar interests in alternative investment funds such as leveraged buyout, mezzanine or real estate focused funds.

Since the beginning of the financial crisis that began in mid-2007, we have been at the forefront of providing independent advice to governments and governmental agencies challenged by the current troubled environment. Lazard’s Sovereign Advisory Group is also highly active, advising a number of countries with respect to sovereign debt.

On May 10, 2005, Lazard Group transferred its capital markets business, which consisted of equity, fixed income and convertibles sales and trading, broking, research and underwriting services, and fund management activities outside of France as well as other specified non-operating assets and liabilities, to LFCM Holdings LLC (“LFCM Holdings”), a Delaware limited liability company. We refer to these businesses, assets and liabilities as the “separated businesses” and these transfers collectively as the “separation.” In connection with the separation, we entered into a business alliance agreement dated as of May 10, 2005 by and among Lazard Group, LAZ-MD Holdings LLC (“LAZ-MD Holdings”), an entity owned by Lazard Group’s current and former managing directors (including certain executive officers), and LFCM Holdings (the “business alliance agreement”), pursuant to which a subsidiary of LFCM Holdings generally underwrites and distributes U.S. securities offerings originated by our Financial Advisory business in a manner intended to be similar to our practice prior to the separation, with revenue from such offerings generally continuing to be divided evenly between Lazard Group and LFCM Holdings.

Staffing

We staff our assignments with a team of quality professionals who have appropriate product and industry expertise. We pride ourselves on, and we believe we differentiate ourselves from our competitors by, being able to offer a high level of attention from senior personnel to our clients and organizing ourselves in such a way that

3

managing directors who are responsible for securing and maintaining client relationships also actively participate in providing related transaction execution services. Our managing directors have significant experience, and many of them are able to use this experience to advise on M&A, financings, restructurings, capital structure and other transactions or financial matters, depending on our clients’ needs. Many of our managing directors and senior advisors come from diverse backgrounds, such as senior executive positions at corporations and in government, law and strategic consulting, which we believe enhances our ability to offer sophisticated advice and customized solutions to our clients. As of December 31, 2011, our Financial Advisory segment had 140 managing directors and 730 other professionals (which includes directors, vice presidents, associates and analysts).

Industries Served

We seek to offer our services across most major industry groups, including, in many cases, sub-industry specialties. Our Mergers and Acquisitions managing directors and professionals are organized to provide advice in the following major industry practice areas:

• consumer,

• financial institutions,

• healthcare and life sciences,

• industrial,

• power and energy/infrastructure,

• real estate, and

• technology, media and telecommunications.

These groups are managed locally in each relevant geographic region and are coordinated globally, which allows us to bring local industry-specific knowledge to bear on behalf of our clients on a global basis. We believe that this enhances the quality of the advice that we can offer, which improves our ability to market our capabilities to clients.

In addition to our Mergers and Acquisitions and Restructuring practices, we also maintain specialties in the following distinct practice areas within our Financial Advisory segment:

• government advisory,

• capital structure and debt advisory,

• fund raising for alternative investment funds,

• private investment in public equities, or “PIPES,” and

• corporate finance and other advisory services, including convertible exchange transactions, registered direct offerings and private placements.

We endeavor to coordinate the activities of the professionals in these areas with our Mergers and Acquisitions industry specialists in order to offer clients customized teams of cross-functional expertise spanning both industry and practice area expertise.

Strategy

Our focus in our Financial Advisory business is on:

• making a significant investment in our intellectual capital with the addition of senior professionals who we believe have strong client relationships and industry expertise,

4

• increasing our contacts with existing clients to further enhance our long-term relationships and our efforts in developing new client relationships,

• developing new client relationships, including by leveraging the broad geographic footprint and strong relationships in our Asset Management business,

• expanding the breadth and depth of our industry expertise and selectively adding or reinforcing practice areas, such as our Capital Structure Advisory, Debt Advisory and Sovereign Advisory Groups, to help corporations and governments in addressing the significant deleveraging that is occurring in the developed markets,

• coordinating our industry specialty activities on a global basis and increasing the integration of our industry experts in Mergers and Acquisitions with our Restructuring, Capital Markets and other professionals, and

• broadening our geographic presence by adding new offices, including, since the beginning of 2007, offices in Australia (Melbourne and Perth), Saudi Arabia (Riyadh), Switzerland (Zurich) and the United Arab Emirates (Dubai City), as well as new regional offices in the U.S. (Boston, Minneapolis, Charlotte and Washington DC), acquiring a 50% interest in a financial advisory firm with offices in Central and South America (Argentina, Chile, Colombia, Panama, Peru and Uruguay) and entering into a joint cooperation agreement in Eastern Europe and Russia, as well as a strategic alliance with a financial advisory firm in Mexico.

In addition to the investments made as part of this strategy, we believe that our Financial Advisory business may benefit from external market factors, including:

• increasing demand for independent, unbiased financial advice, and

• a potential increase in cross-border M&A and large capitalization M&A, two of our areas of historical specialization.

Going forward, our strategic emphasis in our Financial Advisory business is to leverage the investments we have made in recent years to grow our business and drive our productivity. We continue to seek to opportunistically attract outstanding individuals to our business. We routinely reassess our strategic position and may in the future seek opportunities to further enhance our competitive position. In this regard, since 2007, as described above, we have broadened our geographic footprint through acquisitions, investments and alliances.

Recapitalization and Relationship with Natixis

On May 10, 2005, we completed the equity public offering (the “equity public offering”) of Class A common stock of Lazard Ltd (“Class A common stock” or “common stock”), the public offering of equity security units of Lazard Ltd, the private placements under an investment agreement with IXIS Corporate & Investment Bank (“IXIS” or, following its merger with and into its parent, “Natixis”) and the private offering of the 7.125% senior notes due 2015 of Lazard Group, primarily to recapitalize Lazard Group. We refer to these financing transactions and the recapitalization, collectively, as the “recapitalization.” As part of the recapitalization, Lazard Group used the net proceeds from the financing transactions primarily to redeem the outstanding Lazard Group membership interests of certain of its historical partners.

Lazard Group and Natixis have in place a cooperation arrangement to place and underwrite securities in the French capital markets under a common brand, currently “Lazard-Natixis,” and cooperate in their respective origination, syndication, placement and other activities, whose term continues through July 8, 2012. This arrangement primarily covers French listed companies included in the Société des Bourses Francaises (“SBF”) 120 Index and initial public offerings with an expected resulting market capitalization of at least €500 million.

Asset Management

Our Asset Management business provides investment management and advisory services to institutional clients, financial intermediaries, private clients and investment vehicles around the world. Our goal in our Asset Management business is to produce superior risk-adjusted investment returns and provide investment solutions customized for our clients. Many of our equity investment strategies share an investment philosophy that centers on fundamental security selection with a focus on the trade-off between a company’s valuation and its financial productivity.

As of December 31, 2011, total assets under management (“AUM”) were $141 billion, of which approximately 83% was invested in equities, 12% in fixed income, 4% in alternative investments and 1% in private equity funds. As of the same date, approximately 29% of our AUM was invested in international (i.e., non-U.S. and regional non-U.S.) investment strategies, 50% was invested in global investment strategies and 21% was invested in U.S. investment strategies, and our top ten clients accounted for 22% of our total AUM. Approximately 90% of our AUM as of that date was managed on behalf of institutional clients, including corporations, labor unions, public pension funds, insurance companies and banks, and through sub-advisory relationships, mutual fund sponsors, broker-dealers and registered advisors, and approximately 10% of our AUM was managed on behalf of individual client relationships, which are principally with family offices and high-net worth individuals.

The charts below illustrate the mix of our AUM as of December 31, 2011, measured by broad product strategy and by office location.

For the years ended December 31, 2011, 2010 and 2009, our Asset Management segment net revenue totaled $897 million, $850 million and $602 million, respectively, accounting for approximately 49%, 45% and 39% respectively, of our consolidated net revenue for such years. For the years ended December 31, 2011, 2010 and 2009, Asset Management reported operating income of $268 million, $265 million and $97 million, respectively. Operating income in 2010 and 2009 included charges of $3 million and $8 million, respectively, representing the portion of the special items (as described in Management’s Discussion and Analysis of Financial Condition and Results of Operations) that are applicable to the Asset Management segment. Excluding the impact of such special items, our Asset Management segment had operating income of $268 million and $105 million in the years ended December 31, 2010 and 2009, respectively. At December 31, 2011, 2010 and 2009, our Asset Management segment had total assets of $584 million, $687 million and $703 million, respectively.

LAM and LFG

Our largest Asset Management businesses are Lazard Asset Management LLC and its subsidiaries (“LAM”), with offices in New York, San Francisco, Boston, Chicago, Toronto, Montreal, London, Milan, Frankfurt, Hamburg, Tokyo, Hong Kong, Sydney, Seoul, Zurich and Manama (aggregating approximately $127 billion in total AUM as of December 31, 2011), and Lazard Frères Gestion SAS (“LFG”), with offices in Paris, Bordeaux, Brussels and Lyon (aggregating approximately $13 billion in total AUM as of December 31, 2011). These operations, with 63 managing directors and 327 professionals as of December 31, 2011, provide our business with both a global presence and a local identity.

6

Primary distinguishing features of these operations include:

• a global footprint with global research, global mandates and global clients,

• a broad-based team of 259 investment professionals as of December 31, 2011 (LAM, with 228 investment professionals, including 88 focused, in-house investment analysts across all products and platforms, many of whom have substantial industry or sector specific expertise, and LFG, with 31 investment professionals, including research analysts),

• a security selection-based investment philosophy applied across products, and

• world-wide brand recognition and multi-channel distribution capabilities.

Our Investment Philosophy, Process and Research.    Our investment philosophy is generally based upon a fundamental security selection approach to investing. Across many of our products, we apply three key principles to investment portfolios:

• select securities, not markets,

• evaluate the trade-off between returns and valuations, and

• manage risk.

In searching for equity investment opportunities, many of our investment professionals follow an investment process that incorporates several interconnected components that may include:

• analytical framework analysis and screening,

• accounting validation,

• fundamental analysis,

• security selection and portfolio construction, and

• risk management.

In our Asset Management business, we conduct investment research on a global basis to develop market, industry and company specific insights and evaluate investment opportunities. Our global equity analysts, located in our worldwide offices, are organized around six global industry sectors:

• consumer goods,

• financial services,

• health care,

• industrials,

• power, and

• technology, media and telecommunications.

In addition to the primary investment strategies listed above, we also provide locally customized investment solutions to our clients. In many cases, we also offer both diversified and more concentrated versions of our products. These products are generally offered on a separate account basis, as well as through pooled vehicles.

Distribution.    We distribute our products through a broad array of marketing channels on a global basis. LAM’s marketing, sales and client service efforts are organized through a global market delivery and service network, with distribution professionals located in cities including New York, Boston, Chicago, San Francisco,

Tampa, London, Milan, Montreal, Toronto, Frankfurt, Hamburg, Zurich, Tokyo, Sydney, Hong Kong, Manama and Seoul. We have developed a well-established presence in the institutional asset management arena, managing money for corporations, labor unions, sovereign wealth funds and public pension funds around the world. In addition, we manage assets for insurance companies, savings and trust banks, endowments, foundations and charities.

We also have become a leading firm in third-party distribution, managing mutual funds and separately managed accounts for many of the world’s largest broker-dealers, insurance companies, registered advisors and other financial intermediaries. In the area of wealth management, we cater to family offices and private clients.

LFG markets and distributes its products through 28 sales professionals based in France, who directly target both individual and institutional investors.

In June 2009, the Company formed a new wealth management subsidiary, Lazard Wealth Management LLC (“Lazard Wealth Management U.S.”). Lazard Wealth Management U.S. provides customized investment management and financial planning services to high net worth individuals and works with investors to construct, implement and monitor an asset allocation strategy designed to meet the individual client’s investment objectives, integrating tax planning, estate planning, philanthropic interests and legacy planning with investment and risk management services. Lazard Wealth Management U.S. is registered as an investment advisor with the United States Securities and Exchange Commission (the “SEC”). In addition, in December 2011, the Company’s recently formed subsidiary, Lazard Wealth Management Europe S.à.r.l. (“Lazard Wealth Management Europe”), acquired BSI Spain Wealth and Asset Management, S.A. (referred to below as “Lazard Wealth Management Spain”) from BSI, S.A., a unit of Assicurazioni Generali S.p.A., as a platform from which to build a wealth management business and presence in Spain. Lazard Wealth Management Spain, through its two subsidiaries, which are regulated by the Comisión Nacional del Mercado de Valores, will provide high net worth clients with a full range of wealth management services. Lazard Wealth Management U.S. and Lazard Wealth Management Europe are collectively referred to as “Lazard Wealth Management”. As of December 31, 2011, Lazard Wealth Management had 7 managing directors and 6 professionals.

Strategy

Our strategic plan in our Asset Management business is to focus on delivering superior investment performance and client service and broadening our product offerings and distribution in selected areas in order to continue to drive improved business results. Over the past several years, in an effort to improve our Asset Management business’ operations and expand our Asset Management business, we have:

• focused on enhancing our investment performance,

• improved our investment management platform by adding a number of senior investment professionals (including portfolio managers and analysts),

• continued to strengthen our marketing and consultant relations capabilities, including by leveraging the broad geographic footprint and strong client relationships in our Financial Advisory business,

• expanded our product platform, including the addition of a new emerging markets debt team, a global equity team and a global real estate investment team, and

• continued to expand the geographic reach of our Asset Management business, including through opening offices in Hong Kong and Bahrain.

We believe that our Asset Management business has long maintained an outstanding team of portfolio managers and global research analysts. We intend to maintain and supplement our intellectual capital to achieve our goals. We routinely reassess our strategic position and may in the future seek acquisitions or other transactions, including the opportunistic hiring of new employees, in order to further enhance our competitive position. In this regard, in September 2011, LAM acquired the assets of Grubb & Ellis Alesco Global Advisors,

9

LLC (“Alesco”). Alesco is an investment advisor located in San Mateo, California, focusing on real estate securities and managing three registered mutual funds. We also believe that our specific investment strategies, global reach, unique brand identity and access to multiple distribution channels may allow us to expand into new investment products, strategies and geographic locations. In addition, we plan to expand our participation in alternative investment activities through investments in new and successor funds, through organic growth, acquisitions or otherwise.

Alternative Investments

Lazard has a long history of making investments with its own capital, often alongside capital of qualified institutional and individual investors. These activities typically are organized in funds that make substantial or controlling investments in private or public companies, generally through privately negotiated transactions and with a view to divest within two to seven years. While potentially risky and frequently illiquid, such investments, when successful, can yield investors substantial returns on capital and generate attractive management and performance fees for the sponsor of such funds.

Since 2005, consistent with our obligations to LFCM Holdings, we have engaged in a number of alternative investments and private equity activities. In February 2009 the business alliance agreement with LFCM Holdings was amended to remove certain restrictions on the Company engaging in private equity businesses in North America and to reduce the price of our option to acquire the fund management activities of Lazard Alternative Investments Holdings LLC (“LAI”) in North America. In that regard, on July 15, 2009, the Company established a private equity business with The Edgewater Funds (“Edgewater”), a Chicago-based private equity firm, through the acquisition of Edgewater’s management vehicles. The acquisition was structured as a purchase by Lazard of interests in a holding company that owns interests in the general partner and management company entities of the current Edgewater private equity funds (the “Edgewater Acquisition”) (see Note 9 of Notes to Consolidated Financial Statements). As of December 31, 2011, Edgewater employed 10 professionals and had approximately $1 billion of AUM and unfunded fee-earning commitments. Lazard Australia operates our private equity business in Australia, which, as of December 31, 2011, employed 6 professionals and had approximately $350 million of AUM and unfunded fee-earning commitments.

LFCM Holdings operates the alternative investment business (including private equity activities) transferred to it in the separation. Pursuant to the business alliance agreement with LFCM Holdings, we are entitled to receive all or a portion of the payments from incentive distributions attributable to capital that we have invested in funds managed or formed by LAI (net of compensation payable to investment professionals who manage these funds). In addition, pursuant to the business alliance agreement, we retained an option to acquire the North American and European fund management activities of LAI and have the right to participate in the oversight of LFCM Holdings’ funds and to consent to certain actions. On December 15, 2009, Lazard Group exercised its option to acquire the European fund management activities of LAI. While the remaining option to purchase the North American fund management activities is currently exercisable at any time prior to May 10, 2014, during the fourth quarter of 2011, the Company determined that it was unlikely to exercise such option (see Note 21 of Notes to Consolidated Financial Statements).

We will continue to abide by our obligations with respect to transferred funds. Also, consistent with our obligations to LFCM Holdings, we may explore discrete capital markets opportunities. See Note 21 of Notes to Consolidated Financial Statements for additional information regarding alternative investments, including certain matters with respect to Corporate Partners II Limited (“CP II”).

Employees

We believe that our people are our most important asset, and it is their reputation, talent, integrity and dedication that underpin our success. As of December 31, 2011, we employed 2,511 people, which included 140 managing directors and 730 other professionals in our Financial Advisory segment and 71 managing directors and 349 other professionals in our Asset Management segment. We strive to maintain a work environment that

10

fosters professionalism, excellence, diversity and cooperation among our employees worldwide. We generally utilize an evaluation process at the end of each year to measure performance, determine compensation and provide guidance on opportunities for improved performance. Generally, our employees are not subject to any collective bargaining agreements, except that our employees in certain of our European offices, including France and Italy, are covered by national, industry-wide collective bargaining agreements. We believe that we have good relations with our employees.

Competition

The financial services industry, and all of the businesses in which we compete, are intensely competitive, and we expect them to remain so. Our competitors are other investment banking and financial advisory firms, broker-dealers, commercial and “universal” banks, insurance companies, investment management firms, hedge fund management firms, alternative investment firms and other financial institutions. We compete with some of our competitors globally and with others on a regional, product or niche basis. We compete on the basis of a number of factors, including quality of people, transaction execution skills, investment track record, quality of client service, individual and institutional client relationships, absence of conflicts, range of products and services, innovation, brand recognition and business reputation.

While our competitors vary by country in our Mergers and Acquisitions practice, we believe our primary competitors in securing M&A advisory engagements are Bank of America Merrill Lynch, Barclays, Citigroup, Credit Suisse, Deutsche Bank AG, Evercore Partners, Goldman Sachs & Co., Greenhill & Co., JPMorgan Chase, Mediobanca, Morgan Stanley, Rothschild and UBS. In our Restructuring practice, our primary competitors are The Blackstone Group, Evercore Partners, Greenhill & Co., Houlihan Lokey, Miller Buckfire, Moelis & Company and Rothschild.

We believe that our primary global competitors in our Asset Management business include, in the case of LAM, Aberdeen and Schroders, Alliance Bernstein, Capital Management & Research, Fidelity, Franklin Templeton, Invesco, JP Morgan Asset Management, Lord Abbett and Mondrian Investment Partners, and, in the case of LFG, private banks with offices in France as well as large institutional banks and fund managers. We face competition in private equity both in the pursuit of outside investors for our private equity funds and the acquisition of investments in attractive portfolio companies. We compete with hundreds of other funds, many of which are subsidiaries of or otherwise affiliated with large financial service providers.

Competition is also intense in each of our businesses for the attraction and retention of qualified employees, and we compete on the level and nature of compensation and equity-based incentives for key employees. Our ability to continue to compete effectively in our businesses will depend upon our ability to attract new employees and retain and motivate our existing employees.

In recent years there has been substantial consolidation and convergence among companies in the financial services industry. In particular, a number of large commercial banks, insurance companies and other broad-based financial services firms have established or acquired broker-dealers or have merged with other financial institutions. This trend was amplified in connection with the unprecedented disruption and volatility in the financial markets during the past several years, and, as a result, a number of financial services companies have merged, been acquired or have fundamentally changed their respective business models, including, in certain cases, becoming bank holding companies or commercial banks. Many of these firms have the ability to offer a wider range of products than we offer, including loans, deposit taking, insurance and brokerage services. Many of these firms also offer more extensive asset management and investment banking services, which may enhance their competitive position. They also may have the ability to support investment banking and securities products with commercial banking, insurance and other financial services revenue in an effort to gain market share, which could result in pricing pressure in our businesses. This trend toward consolidation and convergence has significantly increased the capital base and geographic reach of our competitors, and, in certain instances, has afforded them access to government funds.

11

Regulation

Our businesses, as well as the financial services industry generally, are subject to extensive regulation throughout the world. As a matter of public policy, regulatory bodies are charged with safeguarding the integrity of the securities and other financial markets and with protecting the interests of customers participating in those markets, not with protecting the interests of our stockholders or creditors. Many of our affiliates that participate in securities markets are subject to comprehensive regulations that include some form of minimum capital requirements and customer protection rules. In the U.S., certain of our subsidiaries are subject to such regulations promulgated by the SEC or Financial Industry Regulatory Authority (“FINRA”) (formerly the NASD) or the Municipal Securities Rulemakers Board (the “MSRB”). Standards, requirements and rules implemented throughout the European Union are broadly comparable in scope and purpose to the regulatory capital and customer protection requirements imposed under the SEC and FINRA rules. European Union directives also permit local regulation in each jurisdiction, including those in which we operate, to be more restrictive than the requirements of such European Union-wide directives. These sometimes burdensome local requirements can result in certain competitive disadvantages to us.

In the U.S., the SEC is the federal agency responsible for the administration of the federal securities laws. FINRA is a voluntary, self-regulatory body composed of members, such as our broker-dealer subsidiaries, that have agreed to abide by FINRA’s rules and regulations. The MSRB is also a voluntary, self-regulatory body, composed of members, including “municipal advisors”, that have agreed to abide by the MSRB’s rules and regulations. The SEC, FINRA, MSRB and non-U.S. regulatory organizations may examine the activities of, and may expel, fine and otherwise discipline us and our employees. The laws, rules and regulations comprising this framework of regulation and the interpretation and enforcement of existing laws, rules and regulations are constantly changing, particularly in light of the extraordinary disruption and volatility in the global financial markets experienced in recent years. The effect of any such changes cannot be predicted and may impact the manner of operation and profitability of our company.

Our principal U.S. broker-dealer subsidiary, Lazard Frères & Co. LLC (“LFNY”), through which we conduct most of our U.S. Financial Advisory business, is currently registered as a broker-dealer with the SEC and FINRA, and as a broker-dealer in all 50 U.S. states, the District of Columbia and Puerto Rico. As such, LFNY is subject to regulations governing effectively every aspect of the securities business, including minimum capital requirements, record-keeping and reporting procedures, relationships with customers, experience and training requirements for certain employees, and business procedures with firms that are not members of certain regulatory bodies. LFNY is also currently registered with the SEC and the MSRB as a municipal advisor, a new registration category that includes placement agents that solicit investments from public pension funds on behalf of investments funds. The MSRB has adopted, and is in the process of adopting, additional rules to govern municipal advisors, including “pay-to-play” rules and rules regarding professional standards, and LFNY is subject to those rules. Lazard Asset Management Securities LLC, a subsidiary of LAM, is registered as a broker-dealer with the SEC and FINRA and in all 50 U.S. states, the District of Columbia and Puerto Rico. Lazard Middle Market LLC, a subsidiary of GAHL, is registered as a broker-dealer with the SEC and FINRA, and as a broker-dealer in various U.S. states and territories.

Certain U.K. subsidiaries of Lazard Group, including Lazard & Co., Limited, Lazard Fund Managers Limited and Lazard Asset Management Limited, which we refer to in this Annual Report on Form 10-K (this “Form 10-K”) as the “U.K. subsidiaries,” are regulated by the Financial Services Authority. We also have other subsidiaries that are registered as broker-dealers (or have similar non-U.S. registration in various jurisdictions).

Compagnie Financière Lazard Frères SAS (“CFLF”), our French subsidiary under which asset management and commercial banking activities are carried out in France, is subject to regulation by the Autorité de Contrôle Prudentiel for its banking activities conducted through its subsidiary, our Paris-based banking affiliate, Lazard Frères Banque SA (“LFB”). In addition, the investment services activities of the Paris group, exercised through LFB and other subsidiaries of CFLF, primarily LFG (asset management), are subject to regulation and supervision by the Autorité des Marchés Financiers.

12

Our business is also subject to regulation by non-U.S. governmental and regulatory bodies and self-regulatory authorities in other countries where we operate.

Our U.S. broker-dealer subsidiaries, including LFNY, are subject to the SEC’s uniform net capital rule, Rule 15c3-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the net capital rules of FINRA, which may limit our ability to make withdrawals of capital from our broker-dealer subsidiaries. The uniform net capital rule sets the minimum level of net capital a broker-dealer must maintain and also requires that a portion of its assets be relatively liquid. FINRA may prohibit a member firm from expanding its business or paying cash dividends if it would result in net capital falling below FINRA’s requirements. In addition, our broker-dealer subsidiaries are subject to certain notification requirements related to withdrawals of excess net capital. Our broker-dealer subsidiaries are also subject to regulations, including the USA PATRIOT Act of 2001, which impose obligations regarding the prevention and detection of money-laundering activities, including the establishment of customer due diligence and other compliance policies and procedures. Failure to comply with these requirements may result in monetary, regulatory and, in certain cases, criminal penalties.

Certain of our Asset Management subsidiaries are registered as investment advisors with the SEC. As registered investment advisors, each is subject to the requirements of the Investment Advisers Act and the SEC’s regulations thereunder. Such requirements relate to, among other things, the relationship between an advisor and its advisory clients, as well as general anti-fraud prohibitions. LAM serves as an advisor to several mutual funds which are registered under the Investment Company Act. The Investment Company Act regulates, among other things, the relationship between a mutual fund and its investment advisor (and other service providers) and prohibits or severely restricts principal transactions between an advisor and its advisory clients, imposes record- keeping and reporting requirements, disclosure requirements, limitations on trades where a single broker acts as the agent for both the buyer and seller (known as “agency cross”), and limitations on affiliated transactions and joint transactions. Lazard Asset Management Securities LLC, a subsidiary of LAM, serves as the underwriter or distributor for mutual funds and hedge funds managed by LAM, and as an introducing broker to Lazard Capital Markets LLC for unmanaged accounts of LAM’s private clients.

In addition, the Japanese Ministry of Finance and the Financial Supervisory Agency, the Korean Financial Supervisory Commission, the Australian Securities & Investments Commission and German banking authorities, among others, regulate various of our operating entities and also have capital standards and other requirements comparable to the rules of the SEC.

Regulators are empowered to conduct administrative proceedings that can result in censure, fine, the issuance of cease-and-desist orders or the suspension or expulsion or other disciplining of a broker-dealer or its directors, officers or employees.

Lazard Ltd had been subject to supervision by the SEC as a Supervised Investment Bank Holding Company (“SIBHC”). As a SIBHC, Lazard Ltd was subject to group-wide supervision, which required it to compute allowable capital and risk allowances on a consolidated basis. However, pursuant to Section 617 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the SEC’s SIBHC program was eliminated on July 21, 2011. Pursuant to relevant rules in the European Union, Lazard Ltd is required to be supervised by another regulatory body, either in the U.S. or the European Union. The Dodd-Frank Act allows certain securities holding companies seeking consolidated supervision, including Lazard Ltd, to elect to be supervised by the Board of Governors of the Federal Reserve. Lazard Ltd anticipates that the Board of Governors of the Federal Reserve will adopt regulations pursuant to Section 618 of the Dodd-Frank Act in the near future for companies that seek to come under its consolidated supervision. Once it analyzes the final scope of such regulations, Lazard Ltd will determine whether it will elect to register to come under the consolidated supervision of the Federal Reserve. Until such regulations are adopted, however, we cannot determine the full impact of such regulations on us. The Dodd-Frank Act and the rules and regulations that may be adopted thereunder (including regulations that have not yet been proposed) could have other effects on us. We continue to monitor the process as such rules are proposed and adopted. See “Risk Factors—Other Business Risks—Extensive regulation of our

13

businesses limits our activities and results in ongoing exposure to the potential for significant penalties, including fines or limitations on our ability to conduct our businesses.”

Over the last several years, global financial markets experienced extraordinary disruption and volatility. As a result, the U.S. and other governments have taken actions, and may continue to take further actions, in response to this disruption and volatility, including expanding current or enacting new standards, requirements and rules that may be applicable to us and our subsidiaries. The effect of any such expanded or new standards, requirements and rules is uncertain and could have adverse consequences to our business and results of operations.

ITEM 1A. RISK FACTORS

You should carefully consider the following risks and all of the other information set forth in this Form 10-K, including our consolidated financial statements and related notes. The following risks comprise material risks of which we are aware. If any of the events or developments described below actually occurred, our business, financial condition or results of operations would likely suffer.

Risks Relating to the Financial Services Industry and Financial Markets

In recent years, the U.S. and global capital markets and the economy experienced periods of significant deterioration and volatility, which has had negative repercussions on the global economy, and any continued deterioration and volatility could present challenges for our business.

In recent years, certain adverse financial developments have impacted the U.S. and global capital markets. These developments included a general slowing of economic growth both in the U.S. and globally, periods of substantial volatility in equity securities markets and volatility and tightening of liquidity in credit markets. In addition, concerns over high unemployment levels, declining business and consumer confidence, volatile energy costs, geopolitical issues and a weak real estate market in the U.S. and elsewhere have contributed to increased volatility and diminished expectations for the economy and the markets going forward. Significant levels of volatility in the equity securities markets and credit markets continue at the present time. In addition, investor concerns about the financial health of certain European countries and financial institutions caused market disruptions in 2010 and 2011 and may continue to cause disruption in future periods. If significant levels of market disruption and volatility continue, or if current conditions materially worsen, our business may be adversely affected, which may have a material impact on our business and results of operations.

15

The full extent of the effects of governmental economic and regulatory involvement in the wake of disruption and volatility in global financial markets remains uncertain.

As a result of market volatility and disruption in recent years, the U.S. and other governments have taken unprecedented steps to try to stabilize the financial system, including investing in financial institutions and taking certain regulatory actions. The full extent of the effects of these actions and legislative and regulatory initiatives (including the Dodd-Frank Act) effected in connection with, and as a result of, such extraordinary disruption and volatility is uncertain, both as to the financial capital markets and participants in general, and as to us in particular.

The level of soundness of third parties, including our clients, as well as financial, governmental and other institutions, could adversely affect us.

We have exposure to many different industries, institutions, products and counterparties, and we routinely execute transactions with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds and other institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be exacerbated when the collateral held by us cannot be fully realized or is liquidated at prices not sufficient to recover the full amount of the loan or derivative exposure due us.

Our share price may decline due to the large number of our common shares eligible for future sale and for exchange.

As of December 31, 2011, our authorized and unissued shares of Class A common stock include (i) approximately 6.8 million shares of our common stock underlying the outstanding LAZ-MD Holdings exchangeable membership interests and (ii) approximately 20.8 million and approximately 141 thousand shares of our common stock underlying the restricted stock units (“RSUs”) and deferred stock units (“DSUs”), respectively, that have been granted pursuant to Lazard Ltd’s 2005 Equity Incentive Plan (the “2005 Plan”) and 2008 Incentive Compensation Plan (the “2008 Plan”). RSUs generally require future service, among other requirements, as a condition for the delivery of the underlying shares of our Class A common stock (unless the recipient is then eligible for retirement under the Company’s retirement policy) and convert into Class A common stock on a one-for-one basis after the stipulated vesting periods. In addition, as of December 31, 2011, approximately 1.1 million shares of our common stock are issuable in connection with the Edgewater Acquisition, which shares will be issued only if certain performance thresholds for the next two Edgewater funds are met.

We have generally withheld a portion of the Class A common stock issued to our executive officers and employees upon vesting of RSUs or delivery of restricted stock to permit the payment of tax liabilities. In addition, we have historically repurchased in the open market and through privately negotiated transactions a significant number of shares of our common stock. If we were to cease to or were unable to repurchase shares of our common stock, the number of shares outstanding would increase over time, diluting the ownership of our existing stockholders. Furthermore, we cannot predict whether, when and how many shares of our common stock will be sold into the market and the effect, if any, that the possibility of market sales of shares of our common stock, the actual sale of such shares or the availability of such shares will have on the market price of our common stock or our ability to raise capital through the issuance of equity securities from time to time.

Other Business Risks

Our ability to retain our managing directors and other key professional employees is critical to the success of our business, including maintaining compensation levels at an appropriate level of costs, and failure to do so may materially adversely affect our results of operations and financial position.

Our people are our most important resource. We must retain the services of our managing directors and other key professional employees, and strategically recruit and hire new talented employees, to obtain and successfully execute the advisory and asset management engagements that generate substantially all our revenue.

16

Lazard Group has experienced several significant events in recent years. In general, our industry continues to experience change and exerts competitive pressures for retaining top talent, which makes it more difficult for us to retain professionals. If any of our managing directors and other key professional employees were to join an existing competitor, form a competing company or otherwise leave us, some of our clients could choose to use the services of that competitor or some other competitor instead of our services. The employment arrangements, non-competition agreements and retention agreements we have or will enter into with our managing directors and other key professional employees may not prevent our managing directors and other key professional employees from resigning from practice or competing against us. In addition, these arrangements and agreements have a limited duration and will expire after a certain period of time. We continue to be subject to intense competition in the financial services industry regarding the recruitment and retention of key professionals, and have experienced departures from and added to our professional ranks as a result. Certain changes to our employee compensation arrangements, such as changes to the composition between cash and deferred compensation, may result in increased compensation and benefits expense in a particular year. Our compensation levels, results of operations and financial position may be significantly affected by many factors, including general economic and market conditions, our operating and financial performance, staffing levels and competitive pay conditions.

Difficult market conditions can adversely affect our business in many ways, including by reducing the volume of the transactions involving our Financial Advisory business and reducing the value or performance of the assets we manage in our Asset Management business, which, in each case, could materially reduce our revenue or income and adversely affect our financial position.

As a financial services firm, our businesses are materially affected by conditions in the global financial markets and economic conditions throughout the world. The financial environment in the U.S. and globally has been volatile during recent years. Unfavorable economic and market conditions can adversely affect our financial performance in both the Financial Advisory and Asset Management businesses.

For example, revenue generated by our Financial Advisory business is directly related to the volume and value of the transactions in which we are involved. During periods of unfavorable market or economic conditions, the volume and value of M&A transactions may decrease, thereby reducing the demand for our Financial Advisory services and increasing price competition among financial services companies seeking such engagements. Our results of operations would be adversely affected by any such reduction in the volume or value of M&A transactions. In addition, our profitability would be adversely affected due to our fixed costs and the possibility that we would be unable to scale back other costs within a timeframe sufficient to offset any decreases in revenue relating to changes in market and economic conditions. The future market and economic climate may deteriorate because of many factors, including possible increases in interest rates, inflation, corporate or sovereign defaults, terrorism or political uncertainty.

Within our Financial Advisory business, we have typically seen that, during periods of economic strength and growth, our Mergers and Acquisitions practice historically has been more active and our Restructuring practice has been less active. Conversely, during periods of economic weakness and slowdown, we typically have seen that our Restructuring practice has been more active and our Mergers and Acquisitions practice has been less active. As a result, our revenue from our Restructuring practice has tended to correlate negatively to our revenue from our Mergers and Acquisitions practice over the course of business cycles. These trends are cyclical in nature and subject to periodic reversal. However, these trends do not cancel out the impact of economic conditions in our Financial Advisory business, which may be adversely affected by a downturn in economic conditions leading to decreased Mergers and Acquisitions practice activity, notwithstanding improvements in our Restructuring practice. Moreover, revenue improvements in our Mergers and Acquisitions practice in strong economic conditions could be offset in whole or in part by any related revenue declines in our Restructuring practice. While we generally have experienced a counter-cyclical relationship between our Mergers and Acquisitions practice and our Restructuring practice, this relationship may not continue in the future.

Our Asset Management business also would be expected to generate lower revenue in a market or general economic downturn. Under our Asset Management business’ arrangements, investment advisory fees we receive

17

typically are based on the market value of AUM. Accordingly, a decline in the prices of securities, such as that which occurred on a global basis in 2008, or in specific geographic markets or sectors that constitute a significant portion of our AUM (e.g., our emerging markets strategies), would be expected to cause our revenue and income to decline by causing:

• the value of our AUM to decrease, which would result in lower investment advisory fees,

• some of our clients to withdraw funds from our Asset Management business due to the uncertainty or volatility in the market, or in favor of investments they perceive as offering greater opportunity or lower risk, which would also result in lower investment advisory fees,

• some of our clients or prospective clients to hesitate in allocating assets to our Asset Management business due to the uncertainty or volatility in the market, which would also result in lower investment advisory fees, or

• negative absolute performance returns for some accounts which have performance-based incentive fees, which would result in a reduction of revenue from such fees.

If our Asset Management revenue declines without a commensurate reduction in our expenses, our net income would be reduced. In addition, in the event of a market downturn, our alternative investment and private equity practices also may be impacted by a difficult fund raising environment and reduced exit opportunities in which to realize the value of their investments. Fluctuations in foreign currency exchange rates may also affect the levels of our AUM and our investment advisory fees. See “Fluctuations in foreign currency exchange rates could reduce our stockholders’ equity and net income or negatively impact the portfolios of our Asset Management clients and may affect the levels of our AUM” below.

A majority of our revenue is derived from Financial Advisory fees, which are not long-term contracted sources of revenue and are subject to intense competition, and declines in our Financial Advisory engagements could have a material adverse effect on our financial condition and results of operations.

We historically have earned a substantial portion of our revenue from advisory fees paid to us by our Financial Advisory clients, which usually are payable upon the successful completion of a particular transaction or restructuring. For example, for the year ended December 31, 2011, Financial Advisory services accounted for approximately 54% of our consolidated net revenue. We expect that we will continue to rely on Financial Advisory fees for a substantial portion of our revenue for the foreseeable future, and a decline in our advisory engagements or the market for advisory services would adversely affect our business, financial condition and results of operations.

In addition, we operate in a highly competitive environment where typically there are no long-term contracted sources of revenue. Each revenue-generating engagement typically is separately awarded and negotiated. Furthermore, many businesses do not routinely engage in transactions requiring our services and, as a consequence, our fee paying engagements with many clients are not likely to be predictable. We also lose clients each year as a result of the sale or merger of a client, a change in a client’s senior management, competition from other financial advisors and financial institutions and other causes. As a result, our engagements with clients are constantly changing and our Financial Advisory fees could decline quickly due to the factors discussed above.

There will not be a consistent pattern in our financial results from period to period, which may make it difficult for us to achieve steady earnings growth on a quarterly basis.

We experience significant fluctuations in quarterly revenue and profits. These fluctuations generally can be attributed to the fact that we earn a significant portion of our Financial Advisory revenue upon the successful completion of a transaction or a restructuring, the timing of which is uncertain and is not subject to our control. In addition, our Asset Management revenue is particularly sensitive to fluctuations in our AUM. Asset Management fees are often based on AUM as of the end of a quarter or month. As a result, a reduction in assets at the end of a quarter or month (as a result of market depreciation, withdrawals or otherwise) will result in a

18

decrease in management fees. Similarly, timing of flows, contributions and withdrawals are often out of our control and may be inconsistent from quarter to quarter. As a result of quarterly fluctuations, it may be difficult for us to achieve steady earnings growth on a quarterly basis.

In many cases, we are paid for advisory engagements only upon the successful consummation of the underlying transaction or restructuring. As a result, our Financial Advisory business is highly dependent on market conditions and the decisions and actions of our clients, interested third parties and governmental authorities. For example, a client could delay or terminate an acquisition transaction because of a failure to agree upon final terms with the counterparty, failure to obtain necessary regulatory consents or board of directors or stockholder approval, failure to secure necessary financing, adverse market conditions or because the target’s business is experiencing unexpected operating or financial problems. Anticipated bidders for assets of a client during a restructuring transaction may not materialize or our client may not be able to restructure its operations or indebtedness, for example, due to a failure to reach agreement with its principal creditors. In addition, a bankruptcy court may deny our right to collect a “success” or “completion” fee. In these circumstances, other than in engagements where we receive monthly retainers, we often do not receive any advisory fees other than the reimbursement of certain expenses despite the fact that we devote resources to these transactions. Accordingly, the failure of one or more transactions to close either as anticipated or at all could materially adversely affect our business, financial condition or results of operations. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

If the number of debt defaults, bankruptcies or other factors affecting demand for our Restructuring services declines, our Restructuring practice’s revenue could suffer.

We provide various restructuring and restructuring-related advice to companies in financial distress or to their creditors or other stakeholders. Historically, the fees from restructuring related services have been a significant part of our Financial Advisory revenue. A number of factors could affect demand for these advisory services, including improving general economic conditions, the availability and cost of debt and equity financing and changes to laws, rules and regulations, including deregulation or privatization of particular industries and those that protect creditors.

We could lose clients and suffer a decline in our Asset Management revenue and earnings if the investments we choose in our Asset Management business perform poorly or if we lose key employees, regardless of overall trends in the prices of securities.

Investment performance affects our AUM relating to existing clients and is one of the most important factors in retaining clients and competing for new Asset Management business. Poor investment performance could impair our revenue and growth because:

• existing clients might withdraw funds from our Asset Management business in favor of better performing products, which would result in lower investment advisory fees,

• our incentive fees, which provide us with a set percentage of returns on some alternative investment and private equity funds and other accounts, would decline,

• third-party financial intermediaries, rating services, advisors or consultants may rate our products poorly, which may result in client withdrawals and reduced asset flows, or

• firms with which we have strategic alliances may terminate such relationships with us, and future strategic alliances may be unavailable.

If key employees were to leave our Asset Management business, whether to join a competitor or otherwise, we may suffer a decline in revenue or earnings and suffer an adverse effect on our financial position. Loss of key employees may occur due to perceived opportunity for promotion, increased compensation, work environment or other individual reasons, some of which may be beyond our control.

19

Our investment style in our Asset Management business may underperform other investment approaches, which may result in significant client or asset departures, or a reduction in AUM.

Even when securities prices are rising generally, performance can be affected by investment style. Many of the equity investment strategies in our Asset Management business share a common investment orientation towards fundamental security selection. We believe this style tends to outperform the market in some market environments and underperform it in others. In particular, a prolonged growth environment may cause certain investment strategies to go out of favor with some clients, advisors, consultants or third-party intermediaries. In combination with poor performance relative to peers, changes in personnel, extensive periods in particular market environments or other difficulties, the underperformance of our investment style may result in significant client or asset departures or a reduction in AUM.

Because many of our Asset Management clients can remove the assets we manage on short notice, we may experience unexpected declines in revenue and profitability.

Our investment advisory contracts are generally terminable upon very short notice. Institutional and individual clients, and firms with which we have strategic alliances, can terminate their relationship with us, reduce the aggregate amount of AUM or shift their funds to other types of accounts with different rate structures for a number of reasons, including investment performance, changes in prevailing interest rates and financial market performance. Poor performance relative to other investment management firms tends to result in decreased investments in our investment products, increased redemptions of our investment products, and the loss of institutional or individual accounts or strategic alliances. In addition, the ability to terminate relationships may allow clients to renegotiate for lower fees paid for asset management services.

In addition, in the U.S., as required by the Investment Company Act, each of our investment advisory contracts with the mutual funds we advise or subadvise automatically terminates upon its “assignment.” Each of our other investment advisory contracts subject to the provisions of the Investment Advisers Act provide, as required by the act, that the contract may not be “assigned” without the consent of the customer. A sale of a sufficiently large block of shares of our voting securities or other transactions could be deemed an “assignment” in certain circumstances. An assignment, actual or constructive, would trigger these termination provisions and could adversely affect our ability to continue managing client accounts.

Access to clients through intermediaries is important to our Asset Management business, and reductions in referrals from such intermediaries or poor reviews of our products or our organization by such intermediaries could materially reduce our revenue and impair our ability to attract new clients.

Our ability to market our Asset Management services relies in part on receiving mandates from the client base of national and regional securities firms, banks, insurance companies, defined contribution plan administrators, investment consultants and other intermediaries. To an increasing extent, our Asset Management business uses referrals from accountants, lawyers, financial planners and other professional advisors. The inability to have this access could materially adversely affect our Asset Management business. In addition, many of these intermediaries review and evaluate our products and our organization. Poor reviews or evaluations of either the particular product or of us may result in client withdrawals or an inability to attract new assets through such intermediaries.

Our historical investment activities involve increased levels of investments in relatively high-risk, illiquid assets, and we may lose some or all of the principal amount that we invest in these activities or fail to realize any profits from these activities for a considerable period of time.

During July 2009, the Company established a private equity business with Edgewater. We may expand our participation in alternative investment activities through investments in new and successor funds, including funds managed by Lazard Australia.

20

The revenue from this business is derived primarily from management fees, which are calculated as a percentage of committed capital or invested capital depending on the stage of each respective fund, transaction and advisory fees and incentive fees, which are earned if investments are profitable over a specified threshold. Our ability to form new alternative investment funds is subject to a number of uncertainties, including past performance of our funds, market or economic conditions, competition from other fund managers and the ability to negotiate terms with major investors.

Furthermore, we have made, and in the future may make, principal investments in public or private companies or in alternative investments (including private equity funds and special purpose acquisition companies) established by us or by LFCM Holdings, and continue to hold principal investments directly or through several funds managed by LFCM Holdings, Edgewater and Lazard Australia. Making principal investments is risky, and we may lose some or all of the principal amount of our investments. Certain of these types of investments may be in relatively high-risk, illiquid assets. Because it may take several years before attractive alternative investment opportunities are identified, some or all of the capital committed by us to these funds is likely to be invested in government securities, other short-term, highly rated debt securities and money market funds that traditionally have offered investors relatively lower returns. In addition, these investments may be adjusted for accounting purposes to fair value at the end of each quarter, and our allocable share of any such gains or losses will affect our revenue, even though such fair value fluctuations may have no cash impact, which could increase the volatility of our earnings. It takes a substantial period of time to identify attractive alternative investment opportunities, to raise all the funds needed to make an investment and then to realize the cash value of an investment through resale. Even if an alternative investment proves to be profitable, it may be several years or longer before any profits can be realized in cash or other proceeds.

Our results of operations may be affected by market fluctuations related to positions held in our investment portfolios.

We invest capital in various types of equity and debt securities in order to seed LAM equity and alternative investment funds, and for general corporate purposes. Such investments are subject to market fluctuations due to changes in the market prices of securities, interest rates or other market factors, such as liquidity. While we may seek to hedge the market risk for some of these investments, the hedge may not be effective or the investments may not be able to be hedged. These investments are adjusted for accounting purposes to fair value at the end of each quarter regardless of our intended holding period, with such gains or losses reflected in revenue, and therefore may increase the volatility of our earnings, even though such gains or losses may not be realized.

We face strong competition from financial services firms, many of whom have the ability to offer clients a wider range of products and services than we can offer, which could lead to pricing pressures that could materially adversely affect our revenue and profitability.

The financial services industry is intensely competitive, and we expect it to remain so. We compete on the basis of a number of factors, including the quality of our advice, employees and transaction execution, our products and services, innovation, reputation and price. We have experienced intense fee competition in some of our businesses in recent years, and we believe that we may experience pricing pressures in these and other areas in the future as some of our competitors seek to obtain increased market share by reducing fees.

We face increased competition due to a trend toward consolidation. In recent years, there has been substantial consolidation and convergence among companies in the financial services industry. In particular, a number of large commercial banks, insurance companies and other broad-based financial services firms have established or acquired broker-dealers or have merged with other financial institutions. This trend was amplified in connection with the unprecedented disruption and volatility in the financial markets during the past several years and, as a result, a number of financial services companies have merged, been acquired or have fundamentally changed their respective business models. Many of these firms have the ability to offer a wide range of products, from loans, deposit-taking and insurance to brokerage, asset management and investment banking services, which may enhance their competitive position. They may also have the ability to support

21

investment banking, including financial advisory services, with commercial banking, insurance and other financial services in an effort to gain market share, which could result in pricing pressure in our businesses.

The financial services industry, and all of the businesses in which we compete, are intensely competitive.

The financial services industry, and all of the businesses in which we compete, are intensely competitive, and we expect them to remain so. In particular, a number of factors increase the competitive risks of our Asset Management business:

• a number of our competitors have more experience, greater financial and other resources and more personnel than we do;

• there are relatively few barriers to entry impeding the launch of new asset management firms, including a relatively low cost of entering these businesses, and the successful efforts of new entrants into our various lines of business, including major banks and other financial institutions, have resulted in increased competition;

• other industry participants will from time to time seek to recruit our investment professionals and other employees away from us in order to compete in our lines of business; and

• certain of our asset management products are newly established and relatively small.

This competitive pressure could adversely affect our ability to make successful investments, retain our personnel and increase AUM, any of which would adversely impact our revenue and earnings.

An inability to access the debt and equity capital markets as a result of our debt obligations, credit ratings or other factors could impair our liquidity, increase our borrowing costs or otherwise adversely affect our competitive position or results of operations.

As of December 31, 2011, Lazard Group and its subsidiaries had approximately $1.1 billion in debt (including capital lease obligations) outstanding, of which $529 million and $548 million relate to Lazard Group senior notes that mature in 2015 and 2017, respectively. This debt has certain mandated payment obligations, which may constrain our ability to operate our business. In addition, in the future we may need to incur debt or issue equity in order to fund our working capital requirements or refinance existing indebtedness, as well as to make acquisitions and other investments. The amount of our debt obligations may impair our ability to raise debt or issue equity for financing purposes. Our access to funds also may be impaired if regulatory authorities take significant action against us, or if we discover that any of our employees had engaged in serious unauthorized or illegal activity. In addition, our borrowing costs and our access to the debt capital markets depend significantly on our credit ratings. These ratings are assigned by rating agencies, which may reduce or withdraw their ratings or place us on “credit watch” with negative implications at any time. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We may pursue acquisitions, joint ventures or cooperation agreements that may result in additional risks and uncertainties in our business and could present unforeseen integration obstacles or costs.

We routinely assess our strategic position and may in the future seek acquisitions or other transactions to further enhance our competitive position. We have in the past pursued joint ventures and other transactions aimed at expanding the geography and scope of our operations. During 2007, we acquired all of the outstanding ownership interests of GAHL and CWC, we entered into a joint cooperation agreement with Raiffeisen and we entered into a shareholders agreement to acquire a 50% interest in MBA. During 2009, we established a private equity business with Edgewater. During 2011, we acquired the assets of Alesco. We expect to continue to explore acquisitions and partnership or strategic alliance opportunities that we believe to be attractive.

22

Acquisitions and joint ventures involve a number of risks and present financial, managerial and operational challenges, including potential disruption of our ongoing business and distraction of management, difficulty with integrating personnel and financial and other systems, hiring additional management and other critical personnel and increasing the scope, geographic diversity and complexity of our operations. Our clients may react unfavorably to our acquisition and joint venture strategy, we may not realize any anticipated benefits from acquisitions, we may be exposed to additional liabilities of any acquired business or joint venture and we may not be able to renew on similar terms (or at all) previously successful joint ventures or similar arrangements, any of which could materially adversely affect our revenue and results of operations.

Employee misconduct, which is difficult to detect and deter, could harm us by impairing our ability to attract and retain clients and subjecting us to significant legal liability and reputational harm.

There have been a number of highly publicized cases involving fraud or other misconduct by employees in the financial services industry generally, and we run the risk that employee misconduct could occur in our business as well. For example, misconduct by employees could involve the improper use or disclosure of confidential information, which could result in legal action, regulatory sanctions and serious reputational or financial harm. Our Financial Advisory business often requires that we deal with client confidences of great significance to our clients, improper use of which may harm our clients or our relationships with our clients. Any breach of our clients’ confidences as a result of employee misconduct may impair our ability to attract and retain Financial Advisory clients and may subject us to liability. Similarly, in our Asset Management business, we have authority over client assets, and we may, from time to time, have custody of such assets. In addition, we often have discretion to trade client assets on the client’s behalf and must do so acting in the best interests of the client. As a result, we are subject to a number of obligations and standards, and the violation of those obligations or standards may adversely affect our clients and us. It is difficult to detect and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in all cases.

The financial services industry faces substantial litigation and regulatory risks, and we may face damage to our professional reputation and legal liability if our services are not regarded as satisfactory or for other reasons.

As a financial services firm, we depend to a large extent on our relationships with our clients and our reputation for integrity and high-caliber professional services to attract and retain clients. As a result, if a client is not satisfied with our services, such dissatisfaction may be more damaging to our business than to other types of businesses. Moreover, our role as advisor to our clients on important transactions involves complex analysis and the exercise of professional judgment, including, if appropriate, rendering “fairness opinions” in connection with mergers and other transactions.

In recent years, the volume of claims and amount of damages claimed in litigation and regulatory proceedings against financial advisors has been increasing. Our Financial Advisory activities may subject us to the risk of significant legal actions by our clients and third parties, including our clients’ stockholders, under securities or other laws for allegations relating to materially false or misleading statements made in connection with securities and other transactions and potential liability for the fairness opinions and other advice provided to participants in corporate transactions. In our Asset Management business, we make investment decisions on behalf of our clients which could result in substantial losses. This also may subject us to the risk of legal actions alleging negligence, misconduct, breach of fiduciary duty or breach of contract. Our Financial Advisory engagements typically include broad indemnities from our clients and provisions designed to limit our exposure to legal claims relating to our services, but these provisions may not protect us or may not be adhered to in all cases. We also are subject to claims arising from disputes with employees for alleged discrimination or harassment, among other things. These risks often may be difficult to assess or quantify, and their existence and magnitude often remain unknown for substantial periods of time. As a result, we may incur significant legal expenses in defending against litigation. Substantial legal liability or significant regulatory action against us could materially adversely affect our business, financial condition or results of operations or cause significant reputational harm to us, which could seriously harm our business.

23

Other operational risks may disrupt our businesses, result in regulatory action against us or limit our growth.

Our business is dependent on communications and information systems, including those of our vendors. Any failure or interruption of these systems, whether caused by fire, other natural disaster, power or telecommunications failure, act of terrorism or war or otherwise, could materially adversely affect our operating results. Although back-up systems are in place, our back-up procedures and capabilities in the event of a failure or interruption may not be adequate.

Particularly in our Asset Management business, we rely heavily on our financial, accounting, trading, compliance and other data processing systems, and those of our third party vendors or service providers who support these functions. We expect that we will need to review whether to continue to upgrade and expand the capabilities of these systems in the future to avoid disruption of, or constraints on, our operations. However, if any of these systems do not operate properly or are disabled, including for reasons beyond our control, we could suffer financial loss, a disruption of our businesses, liability to clients, regulatory intervention or reputational damage. The inability of our systems (or those of our vendors or service providers) to accommodate an increasing volume of transactions also could constrain our ability to expand our businesses.

In addition, if we were to experience a local or regional disaster or other business continuity problem, such as a pandemic or other man-made or natural disaster, our continued success will depend, in part, on the availability of our personnel and office facilities and the proper functioning of our computer, telecommunications, transaction processing and other related systems and operations, as well as those of third parties on whom we rely. Such events could lead us to experience operational challenges, and our inability to successfully recover could materially disrupt our businesses and cause material financial loss, regulatory actions, reputational harm or legal liability.

Extensive regulation of our businesses limits our activities and results in ongoing exposure to the potential for significant penalties, including fines or limitations on our ability to conduct our businesses.

The financial services industry is subject to extensive regulation. We are subject to regulation by governmental and self-regulatory organizations in the jurisdictions in which we operate around the world. Many of these regulators, including U.S. and non-U.S. government agencies and self-regulatory organizations, as well as state securities commissions in the U.S., are empowered to conduct administrative proceedings that can result in censure, fine, the issuance of cease-and-desist orders or the suspension or expulsion of a broker-dealer from registration or membership. The requirements imposed by our regulators are designed to ensure the integrity of the financial markets and to protect customers and other third parties who deal with us and are not designed to protect our stockholders. Consequently, these regulations often serve to limit our activities, including through net capital, customer protection and market conduct requirements.

We face the risk of significant intervention by regulatory authorities, including extended investigation and surveillance activity, adoption of costly or restrictive new regulations and judicial or administrative proceedings that may result in substantial penalties. Among other things, we could be fined or be prohibited from engaging in some of our business activities. In addition, the regulatory environment in which we operate is subject to modifications and further regulation. New laws or regulations or changes in the enforcement of existing laws or regulations applicable to us and our clients also may adversely affect our business, and our ability to function in this environment will depend on our ability to constantly monitor and react to these changes.

In recent years, the U.S. and global financial markets experienced periods of extraordinary disruption and volatility. As a result, the U.S. and other governments have taken actions, and may continue to take further actions, in response to this disruption and volatility, including expanding current or enacting new standards, requirements and rules that may be applicable to us and our subsidiaries. The effect of any such expanded or new standards, requirements and rules is uncertain and could have adverse consequences to our business and results of

24

operations. For example, in July 2010, the Dodd-Frank Act was signed into law, bringing sweeping changes in the regulation of financial institutions. It will take several years for all of the rules under the Dodd-Frank Act to be written and become effective, and the final scope and interpretations of those rules, and their impact on our business, will not be fully known for some time, but could have implications for the manner in which we conduct our business and, consequently, its profitability. While we currently are in the process of examining the potential impact of the Dodd-Frank Act and related regulations, we are not able to predict the ultimate effect on us. In addition, several states and municipalities in the United States have recently adopted “pay-to-play” rules, which could limit our ability to charge fees in connection with certain of our Private Fund Advisory engagements, and could therefore affect the profitability of that portion of our business.

The regulatory environment in which our clients operate may also impact our business. For example, changes in antitrust laws or the enforcement of antitrust laws could affect the level of M&A activity and changes in state laws may limit investment activities of state pension plans.

For asset management businesses in general, there have been a number of highly publicized cases involving fraud or other misconduct by employees of asset management firms, as well as industry-wide regulatory inquiries. These cases and inquiries have resulted in increased scrutiny in the industry and may result in new rules and regulations for mutual funds, hedge funds and their investment managers. This regulatory scrutiny and these rulemaking initiatives may result in an increase in operational and compliance costs or the risk of assessment of significant fines or penalties against our Asset Management business, and may otherwise limit our ability to engage in certain activities.

Financial services firms are subject to numerous conflicts of interest or perceived conflicts. We have adopted various policies, controls and procedures to address or limit actual or perceived conflicts and regularly seek to review and update our policies, controls and procedures. However, these policies and procedures may result in increased costs, additional operational personnel and increased regulatory risk. Failure to adhere to these policies and procedures may result in regulatory sanctions or client litigation.

Specific regulatory changes also may have a direct impact on the revenue of our Asset Management business. In addition to regulatory scrutiny and potential fines and sanctions, regulators continue to examine different aspects of the asset management industry. For example, the use of “soft dollars,” where a portion of commissions paid to broker-dealers in connection with the execution of trades also pays for research and other services provided to advisors, is periodically reexamined and may in the future be limited or modified. Although a substantial portion of the research relied on by our Asset Management business in the investment decision-making process is generated internally by our investment analysts, external research, including external research paid for with soft dollars, is important to the process. This external research generally is used for information gathering or verification purposes, and includes broker-provided research, as well as third-party provided databases and research services. For the year ended December 31, 2011, our Asset Management business obtained research and other services through third-party soft dollar arrangements, the total cost of which we estimate to be approximately $19 million. If the use of soft dollars is limited, we may have to bear some of these costs. In addition, new regulations regarding the management of hedge funds and the use of certain investment products may impact our Asset Management business and result in increased costs. For example, many regulators around the world adopted disclosure and reporting requirements relating to the hedge fund businesses or other businesses. In addition, legislators around the world are exploring regulatory changes and additional oversight of the financial industry generally. The impact of these proposed changes on us are uncertain. These regulatory changes and other proposed or potential changes may result in an increase in costs or a reduction of revenue associated with our Asset Management business.

See “Business—Regulation” for a further discussion of the regulatory environment in which we conduct our businesses.

25

Fluctuations in foreign currency exchange rates could reduce our stockholders’ equity and net income or negatively impact the portfolios of our Asset Management clients and may affect the levels of our AUM.

We are exposed to fluctuations in foreign currencies. Our financial statements are denominated in U.S. Dollars and, for the year ended December 31, 2011, we received approximately 41% of our consolidated net revenue in other currencies, predominantly in euros and British pounds. In addition, we pay a significant amount of our expenses in such other currencies. The exchange rates of these currencies versus the U.S. Dollar affects the carrying value of our assets and liabilities as well as our net income. We do not generally hedge such foreign currency exchange rate exposure arising in our subsidiaries outside of the U.S. Fluctuations in foreign currency exchange rates may also make period to period comparisons of our results of operations difficult.

Foreign currency fluctuations also can impact the portfolios of our Asset Management clients. Client portfolios are invested in securities across the globe, although most portfolios are in a single base currency. Foreign currency fluctuations can adversely impact investment performance for a client’s portfolio. In addition, foreign currency fluctuations may affect the levels of our AUM. As our AUM include significant assets that are denominated in currencies other than U.S. dollars, an increase in the value of the U.S. Dollar relative to non-U.S. currencies may result in a decrease in the dollar value of our AUM, which, in turn, would result in lower U.S. Dollar-denominated revenue in our Asset Management business. While this risk may be limited by foreign currency hedging, some risks cannot be hedged and our hedging activity may not be successful. Poor performance may result in decreased AUM, including as a result of withdrawal of client assets or a decrease in new assets being raised in the relevant product.

See Note 15 of Notes to Consolidated Financial Statements for additional information regarding the impact on stockholders’ equity from currency translation adjustments.

Lazard Ltd is a holding company and, accordingly, depends upon distributions from Lazard Group to pay dividends and taxes and other expenses.

Lazard Ltd is a holding company and has no independent means of generating significant revenue. We control Lazard Group through our indirect control of both of the managing members of Lazard Group. Our wholly-owned subsidiaries incur income taxes on their proportionate share of any net taxable income of Lazard Group in their respective tax jurisdictions. We intend to continue to cause Lazard Group to make distributions to its members, including our wholly-owned subsidiaries, in an amount sufficient to cover all applicable taxes payable by us and dividends, if any, declared by us. To the extent that our subsidiaries need funds to pay taxes on their share of Lazard Group’s net taxable income, or if Lazard Ltd needs funds for any other purpose, and Lazard Group is restricted from making such distributions under applicable law or regulation, or is otherwise unable to provide such funds, it could materially adversely affect our business, financial condition or results of operations.

Lazard Group is a holding company and therefore depends on its subsidiaries to make distributions to Lazard Group to enable it to service its obligations under its indebtedness.

Lazard Group depends on its subsidiaries, which conduct the operations of the businesses, for dividends and other payments to generate the funds necessary to meet its financial obligations, including payments of principal and interest on its indebtedness. However, none of Lazard Group’s subsidiaries is obligated to make funds available to it for servicing such financial obligations. In addition, legal and contractual restrictions in agreements governing current and future indebtedness, as well as financial conditions, minimum regulatory net capital and similar requirements and operating requirements of Lazard Group’s subsidiaries, currently limit and may, in the future, limit Lazard Group’s ability to obtain cash from its subsidiaries. The earnings from, or other available assets of, Lazard Group’s subsidiaries may not be sufficient to pay dividends or make distributions or loans to enable Lazard Group to make payments with respect to its financial obligations when such payments are due. In addition, even if such earnings were sufficient, the agreements governing the current and future

26

indebtedness of Lazard Group’s subsidiaries and regulatory requirements with respect to our broker-dealer and other regulated subsidiaries may not permit such subsidiaries to provide Lazard Group with sufficient dividends, distributions or loans to fund its financial obligations, when due.

We may become subject to taxes in Bermuda after March 28, 2016, which may have a material adverse effect on our results of operations.

The Bermuda Minister of Finance, under the Exempted Undertakings Tax Protection Act 1966 of Bermuda, as amended, has given us an assurance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of any such tax will not be applicable to us or any of our operations, shares, debentures or other obligations until March 28, 2016, except insofar as such tax applies to persons ordinarily resident in Bermuda or to any taxes payable by us in respect of real property owned or leased by us in Bermuda. Given the limited duration of the Bermuda Minister of Finance’s assurance, we may be subject to Bermuda tax after March 28, 2016.

In the event of a change or adverse interpretation of relevant income tax law, regulation or treaty, or a failure to qualify for treaty benefits, our overall tax rate may be substantially higher than the rate used for purposes of our consolidated financial statements.

Our effective tax rate is based upon the application of currently applicable income tax laws, regulations and treaties, current judicial and administrative authorities interpreting those income tax laws, regulations and treaties, and upon our non-U.S. subsidiaries’ ability to qualify for benefits under those treaties, and that a portion of their income is not subject to U.S. tax as effectively connected income. Moreover, those income tax laws, regulations and treaties, and the administrative and judicial authorities interpreting them, are subject to change at any time, and any such change may be retroactive.

Our effective tax rate is based upon our non-U.S. subsidiaries qualifying for treaty benefits, including reduced withholding tax rates, among other things. The eligibility of our non-U.S. subsidiaries for treaty benefits generally depends upon, among other things, at least 50% of the principal class of shares in such subsidiaries being “ultimately owned” by U.S. citizens and persons who are “qualified residents” for purposes of the treaty. It is possible that this requirement may not be met, and even if it is met, we may not be able to document that fact to the satisfaction of the U.S. Internal Revenue Service (“IRS”). If our non-U.S. subsidiaries are not treated as eligible for treaty benefits, such subsidiaries will be subject to additional U.S. taxes, including “branch profits tax” on their “effectively connected earnings and profits” (as determined for U.S. federal income tax purposes) at a rate of 30% rather than a treaty rate of 5%.

The inability, for any reason, to achieve and maintain an overall income tax rate approximately equal to the rate used in preparing our consolidated financial statements could materially adversely affect our business and our results of operations and could materially adversely affect our financial statements.

Tax authorities may challenge our tax computations and classifications and our transfer pricing methods, and their application.

Our tax returns are subject to audit by federal, local and foreign tax authorities. These authorities may successfully challenge certain tax positions or deductions taken by our subsidiaries. For example, tax authorities may contest intercompany allocations of fee income, management charges or interest charges among affiliates in different tax jurisdictions. While we believe that we have provided the appropriate required reserves (see Note 2 of Notes to Consolidated Financial Statements), it is possible that the tax authorities will disagree with all, or a portion, of the tax benefits claimed. If they were to successfully challenge our positions, it could result in significant additional tax costs or payments to LFCM Holdings under the tax receivable agreement.

27

Outcome of future U.S. tax legislation is unknown at the present time.

On February 13, 2012, the Executive Branch presented its 2013 budget proposals to Congress. The budget proposals included several potential revenue generating proposals, including proposals to (i) limit the deduction of certain related party interest and (ii) defer the deduction of interest attributable to foreign source income of foreign subsidiaries. Each of these proposals would be effective only for taxable years beginning after December 31, 2012. In addition, other members of Congress have proposed legislation that, if enacted, would reclassify certain types of publicly-traded entities as U.S. corporations for tax purposes if the management and control of such entities occurs primarily within the U.S.

We are currently unable to predict the ultimate outcome of any of these proposals. If enacted in their current form, however, some of these proposals may increase Lazard’s effective tax rate during future periods.

Our subsidiaries will be required to pay LFCM Holdings most of the benefit relating to any additional tax depreciation or amortization deductions our subsidiaries may claim as a result of the tax basis step-up our subsidiaries receive in connection with the Company’s equity public offering and related transactions.

In connection with our various secondary offerings, LAZ-MD Holdings exchangeable interests were, in effect, partially exchanged for shares of our common stock. Additional exchanges are scheduled to take place in the future. The redemption and the exchanges may result in increases in the tax basis of the tangible and intangible assets of Lazard Group attributable to our subsidiaries’ interest in Lazard Group that otherwise would not have been available. These increases in tax basis may reduce the amount of tax that our subsidiaries would otherwise be required to pay in the future, although the IRS may challenge all or part of that tax basis increase, and a court could sustain such a challenge.

Our subsidiaries entered into a tax receivable agreement with LFCM Holdings that provides for the payment by our subsidiaries to LFCM Holdings of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that we actually realize as a result of these increases in tax basis and of certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. We expect to benefit from the remaining 15% of cash savings realized. Our subsidiaries have the right to terminate the tax receivable agreement at any time for an amount based on an agreed value of certain payments remaining to be made under the tax receivable agreement at such time. While the actual amount and timing of any payments under this agreement will vary depending upon a number of factors, including the timing of exchanges, the extent to which such exchanges are taxable, the allocation of the step-up among the Lazard Group assets, and the amount and timing of our income, we expect that, as a result of the size of the increases in the tax basis of the tangible and intangible assets of Lazard Group attributable to our subsidiaries’ interest in Lazard Group, during the 24-year term of the tax receivable agreement, the payments that our subsidiaries may make to LFCM Holdings could be substantial. As of December 31, 2011, the aggregate increase in tax basis attributable to our subsidiaries’ interest in Lazard Group was approximately $2.9 billion. The aggregate amount, including those interests not yet exchanged, would have been approximately $3.1 billion as of that date (based on the then closing price per share of our common stock on the NYSE of $26.11), including the increase in tax basis associated with the redemption and recapitalization in 2005. The potential future increase in tax basis will depend on the Lazard common stock price at the time of exchange. The cash savings that our subsidiaries would actually realize as a result of this increase in tax basis likely would be significantly less than this amount multiplied by our statutory tax rate due to a number of factors, including insufficient taxable income to absorb the increase in tax basis, the allocation of the increase in tax basis to foreign or non-amortizable assets, the impact of the increase in the tax basis on our ability to use foreign tax credits and the rules relating to the amortization of intangible assets. Our ability to achieve benefits from any such increase, and the payments to be made under this agreement, will depend upon a number of factors, as discussed above, including the timing and amount of our future income.

28

In addition, if the IRS successfully challenges the tax basis increase, under certain circumstances, our subsidiaries could make payments to LFCM Holdings under the tax receivable agreement in excess of our subsidiaries’ cash tax savings.

Failure to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business.

We have documented and tested our internal control procedures in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent auditors regarding our internal control over financial reporting. We are in compliance with Section 404 of the Sarbanes-Oxley Act as of December 31, 2011. However, if we fail to maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act. Failure to maintain an effective internal control environment could have a material adverse effect on our business.

LAZ-MD Holdings, Lazard Group, LFCM Holdings and Lazard Ltd entered into various arrangements, including the master separation agreement, which contain cross-indemnification obligations of LAZ-MD Holdings, Lazard Group, LFCM Holdings and Lazard Ltd, that any party may be unable to satisfy.

The master separation agreement that Lazard Ltd entered into with Lazard Group, LAZ-MD Holdings and LFCM Holdings provides, among other things, that LFCM Holdings generally will indemnify Lazard Ltd, Lazard Group and LAZ-MD Holdings for losses that we incur arising out of, or relating to, the separated businesses and the businesses conducted by LFCM Holdings and losses that Lazard Ltd, Lazard Group or LAZ-MD Holdings incur arising out of, or relating to, LFCM Holdings’ breach of the master separation agreement. In addition, LAZ-MD Holdings generally will indemnify Lazard Ltd, Lazard Group and LFCM Holdings for losses that they incur arising out of, or relating to, LAZ-MD Holdings’ breach of the master separation agreement. Our ability to collect under the indemnities from LAZ-MD Holdings or LFCM Holdings depends on their financial position. For example, persons may seek to hold us responsible for liabilities assumed by LAZ-MD Holdings or LFCM Holdings or, as a result of the use of the Lazard name by subsidiaries of LFCM Holdings, for certain actions of LFCM Holdings or its subsidiaries. If these liabilities are significant and we are held liable for them, we may not be able to recover any or all of the amount of those losses from LAZ-MD Holdings or LFCM Holdings should either be financially unable to perform under their indemnification obligations.

In addition, Lazard Group generally will indemnify LFCM Holdings and LAZ-MD Holdings for liabilities related to Lazard Group’s businesses and Lazard Group will indemnify LFCM Holdings and LAZ-MD Holdings for losses that they incur to the extent arising out of, or relating to, Lazard Group’s or Lazard Ltd’s breach of the master separation agreement. Several of the ancillary agreements that Lazard Group entered into together with the master separation agreement also provide for separate indemnification arrangements. For example, under the administrative services agreement, Lazard Group provides a range of services to LFCM Holdings, including information technology, general office and building services and financing and accounting services, and LFCM Holdings will generally indemnify Lazard Group for liabilities that Lazard Group incurs arising from the provision of these services absent Lazard Group’s intentional misconduct. Lazard Group may face claims for indemnification from LFCM Holdings and LAZ-MD Holdings under these provisions regarding matters for which Lazard Group has agreed to indemnify them. If these liabilities are significant, Lazard Group may be required to make substantial payments, which could materially adversely affect our results of operations. Also, in connection with the CP II MgmtCo Spin-Off (as defined in Note 21 of Notes to Consolidated Financial Statements), the subsidiary of LFCM Holdings that manages CP II MgmtCo (“CP II MgmtCo”) has generally agreed to indemnify us against certain losses related to CP II that arise after the date of closing of the CP II MgmtCo Spin-Off. However, should persons seek to hold us responsible for liabilities assumed by CP II

29

MgmtCo, we may not be able to recover any or all of the amount of our losses from CP II MgmtCo if CP II MgmtCo is financially unable to perform under its indemnification obligations.

We may have potential business conflicts of interest with LAZ-MD Holdings and LFCM Holdings with respect to our past and ongoing relationships that could harm our business operations.

Pursuant to the LAZ-MD Holdings amended and restated stockholders’ agreement, LAZ-MD Holdings will vote the single share of Lazard Ltd Class B common stock, which, as of December 31, 2011, represented approximately 5.2% of Lazard Ltd’s voting power, as directed by its individual members who are party to that agreement. In addition, several employees of Lazard provide services to LFCM Holdings. Conflicts of interest may arise between LFCM Holdings and us in a number of areas relating to our past and ongoing relationships, including:

• labor, tax, employee benefits, indemnification and other matters arising from the separation,

• intellectual property matters,

• business combinations involving us,

• business operations or business opportunities of LFCM Holdings or us that would compete with the other party’s business opportunities, including investment banking by us and the management of alternative investment funds by LFCM Holdings, particularly as some of our managing directors provide services to LFCM Holdings,

• the terms of the master separation agreement and related ancillary agreements, including the operation of the alternative investment fund management business and Lazard Group’s option to purchase the business,

• the nature, quality and pricing of administrative services to be provided by us, and

• the provision of services by certain of our managing directors to LFCM Holdings.

In addition, the administrative services agreement commits us to provide a range of services to LFCM Holdings and LAZ-MD Holdings, which could require the expenditure of significant amounts of time by our management. Our agreements with LAZ-MD Holdings and LFCM Holdings may be amended upon agreement of the parties to those agreements. We may not be able to resolve any potential conflicts and, even if we do, the resolution may be less favorable to us than if we were dealing with a different party.

The use of the “Lazard” brand name by subsidiaries of LFCM Holdings may expose us to reputational harm that could affect our operations and adversely affect our financial position should these subsidiaries take actions that damage the brand name.

The “Lazard” brand name has over 160 years of heritage, connoting, we believe, world-class professional advice, independence and global capabilities with deeply rooted, local know-how. LFCM Holdings operates as a separate legal entity, and Lazard Group licensed to subsidiaries of LFCM Holdings that operate the separated businesses the use of the “Lazard” brand name for certain specified purposes, including in connection with alternative investment fund management and capital markets activities. As these subsidiaries of LFCM Holdings historically have and will continue to use the “Lazard” brand name, and because we no longer control these entities, there is a risk of reputational harm to us if these subsidiaries have, or in the future were to, among other things, engage in poor business practices, experience adverse results or otherwise damage the reputational value of the “Lazard” brand name. These risks could expose us to liability and also may adversely affect our revenue and our business prospects.

Item 3. Legal Proceedings

The Company is involved from time to time in judicial, regulatory and arbitration proceedings and inquiries concerning matters arising in connection with the conduct of our businesses, including proceedings initiated by former employees alleging wrongful termination. The Company reviews such matters on a case-by-case basis and establishes any required accrual if a loss is probable and the amount of such loss can be reasonably estimated. The Company does experience significant variation in its revenue and earnings on a quarterly basis. Accordingly, the results of any pending matter or matters could be significant when compared to the Company’s earnings in any particular fiscal quarter. The Company believes, however, based on currently available information, that the results of any pending matters, in the aggregate, will not have a material effect on its business or financial condition.

Item 4. Mine Safety Disclosures

Not applicable.

Purchases under the share repurchase program may be made in the open market or through privately negotiated transactions. Amounts shown in this line item include repurchases of both Class A common stock and Lazard Group common membership interests, and exclude the shares of Class A common stock withheld by the Company to cover estimated income taxes as described below.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with Lazard Ltd’s consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K (this “Form 10-K”). This discussion contains forward-looking statements that are subject to known and unknown risks and uncertainties. Actual results and the timing of events may differ significantly from those expressed or implied in such forward-looking statements due to a number of factors, including those set forth in the section entitled “Risk Factors” and elsewhere in this Form 10-K.

Business Summary

Lazard is a preeminent financial advisory and asset management firm. We have long specialized in crafting solutions to the complex financial and strategic challenges of a diverse set of clients around the world, including corporations, governments, institutions, partnerships and individuals. Founded in 1848 in New Orleans, we currently operate from 42 cities in key business and financial centers across 27 countries throughout Europe, North America, Asia, Australia, the Middle East and Central and South America.

Our principal sources of revenue are derived from activities in the following business segments:

• Financial Advisory, which offers corporate, partnership, institutional, government, sovereign and individual clients across the globe a wide array of financial advisory services regarding mergers and acquisitions (“M&A”) and other strategic matters, restructurings, capital structure, capital raising and various other financial matters, and

• Asset Management, which includes strategies for the management of equity and fixed income securities and alternative investment and private equity funds, as well as wealth management.

In addition, we record selected other activities in our Corporate segment, including management of cash, certain investments and the commercial banking activities of Lazard Group’s Paris-based Lazard Frères Banque SA (“LFB”). We also allocate outstanding indebtedness to our Corporate segment.

LFB is a registered bank regulated by the Autorité de Contrôle Prudentiel. It is engaged primarily in commercial and private banking services for clients and funds managed by Lazard Frères Gestion SAS (“LFG”) and other clients, investment banking activities, including participation in underwritten offerings of securities in France, asset-liability management and limited trading in securities and foreign exchange.

Our consolidated net revenue was derived from the following segments:

	Year Ended December 31,
	2011			2010			2009
Financial Advisory		54	%		59	%		65	%
Asset Management		49			45			39
Corporate		(3	)		(4	)		(4	)
Total		100	%		100	%		100	%

We also invest our own capital from time to time, generally alongside capital of qualified institutional and individual investors in alternative investments or private equity investments, and, since 2005, we have engaged in a number of alternative investments and private equity activities, including investments through (i) the Edgewater Funds (“Edgewater”), our Chicago-based private equity firm (see Note 9 of Notes to Consolidated Financial Statements), (ii) Lazard Australia Corporate Opportunities Fund 2, which has an opportunistic investment strategy focused on the Australian mid-market, (iii) a mezzanine fund, which invests in mezzanine debt of a diversified selection of small-to mid cap European companies, (iv) Corporate Partners II Limited

37

(“CP II”), a private equity fund targeting significant non-controlling investments in established public and private companies and (v) Lazard Senior Housing Partners LP (“Senior Housing”), which acquires companies and assets in the senior housing, extended stay and shopping center sectors. We continue to explore and discuss opportunities to expand the scope of our alternative investment and private equity activities in Europe, the U.S. and elsewhere. These opportunities could include internal growth of new funds and direct investments by us, partnerships or strategic relationships, investments with third parties or acquisitions of existing funds or management companies. Also, consistent with our obligations to LFCM Holdings LLC (“LFCM Holdings”), we may explore discrete capital markets opportunities.

Business Environment

Economic and global financial market conditions can materially affect our financial performance. As described above, our principal sources of revenue are derived from activities in our Financial Advisory and Asset Management business segments. As our Financial Advisory revenues are for the most part dependent on the successful completion of merger, acquisition, restructuring, capital raising or similar transactions, and our Asset Management revenues are primarily driven by the levels of assets under management (“AUM”), weak economic and global financial market conditions can result in a challenging business environment for M&A and capital-raising activity as well as our Asset Management business, but may provide opportunities for our restructuring business.

Overall, equity market indices at December 31, 2011 reflected little change in the U.S., and declined outside the U.S., when compared to such indices at December 31, 2010, with periods of significant volatility during the year. For the same period, capital-raising and M&A activity were uneven due to economic uncertainty caused by concerns over the scope and depth of the sovereign debt situation in Europe, the U.S. debt ceiling and related rating agency downgrade issues and continuing high U.S. unemployment, among other factors. The announced value of M&A activity increased modestly when compared to 2010. Restructuring activity continued at low levels, reflecting a cyclical decline in restructuring activity and a decrease in the number of corporate defaults.

Entering 2012, the outlook for equity and credit markets appears healthier, interest rates remain low while corporate cash balances remain high, CEO confidence appears to be improving and, as such, companies may be better positioned to make acquisitions for future growth and investors may be increasingly interested in deploying capital for investment purposes. Uncertainty remains, however, with regard to the stability of the global financial system and a variety of other factors.

In recent years, we have expanded our geographic reach, bolstered our industry expertise and continued to build in growth areas. Companies, government bodies and investors seek independent advice with a geographic perspective, deep understanding of capital structure, informed research and knowledge of global economic conditions. We believe that our business model as an independent advisor will continue to create opportunities for us to attract new clients and key personnel. We seek to leverage the power and scale of our firm-wide global network to drive growth in both our Financial Advisory and Asset Management business segments. We believe that we are well positioned to benefit from opportunities that may result from regional or global increases in M&A, restructuring, capital-raising or similar transactions, as well as increases in demand for investment management and advisory services. We continue to focus on the development of our business in this environment and on a wide variety of related factors, including the generation of stable revenue growth during periods of macroeconomic volatility, the prudent management of our costs and expenses and the return of cash to our shareholders.

We operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for our management to predict all risks and uncertainties, nor can we assess the impact of all potentially applicable factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. See the section entitled “Risk Factors” in this Form 10-K. Furthermore, net income and revenue in any period may not be indicative of full-year results or the results of any other period and may vary significantly from year to year and quarter to quarter.

Financial Advisory

As shown in the following table, during 2011 the value and number of completed and announced M&A transactions increased as compared to 2010, despite the overall decline in the value of both announced and completed transactions during the second half of 2011 versus the corresponding prior year period.

Source: Dealogic as of January 16, 2012.

We continue to believe that we are relatively well positioned as our clients refinance, restructure and reposition their asset portfolios for growth.

Global restructuring activity during 2011 decreased from 2010 levels driven by a cyclical decline, resulting in a decelerating pace of corporate debt defaults. According to Moody’s Investors Service, Inc., during 2011 a total of 36 issuers defaulted, as compared to 61 in 2010. While the number and value of corporate defaults for 2011 are significantly lower as compared to 2010, we expect that our Restructuring business will remain active. Our Restructuring activities include advising companies on matters relating to debt restructurings, refinancings and other on- and off-balance sheet assignments. Our Restructuring assignments are generally executed over a six- to eighteen-month period.

Our Private Fund Advisory Group, which is part of our Financial Advisory segment and is conducted in the U.S. through Lazard Frères & Co. LLC (“LFNY”), an SEC-registered broker-dealer and municipal advisor and member of the Financial Industry Regulatory Authority (“FINRA”) and the Municipal Securities Rulemaking Board (the “MSRB”), acts as placement agent for investment funds, including investment funds that have historically received capital from certain public pension funds. In April 2009, governmental officials in New York announced a new policy banning the use of placement agents by funds seeking investment contributions from the New York State and New York City public pension funds. The use of placement agents has also been prohibited or otherwise restricted with respect to investments by public pension funds in Illinois, Ohio, California and New Mexico, and similar measures are being considered or have been implemented in other jurisdictions. On June 22, 2011, the SEC approved an amendment to its June 30, 2010 rule which, among other things, will place certain restrictions on the use of placement agents. As amended, the SEC rule will prohibit investment advisors from paying a third-party placement agent for soliciting investment advisory business from a U.S. governmental entity, unless the placement agent is (i) an SEC-registered investment advisor complying with the rule, (ii) an SEC-registered broker-dealer that is a member of FINRA and thus subject to FINRA’s forthcoming “pay-to-play” rule, or (iii) a “municipal advisor” that is registered with the SEC under Section 15B of the Securities Exchange Act of 1934, as amended, and subject to the “pay-to-play” rules that will be adopted by the MSRB. We are continuing to evaluate the potential impact of state, local and other restrictions on our Private Fund Advisory business.

Asset Management

As shown in the table below, major equity market indices at December 31, 2011 were mixed in the U.S., but declined outside the U.S., when compared to such indices at December 31, 2010. Global market indices at December 31, 2010 increased in most markets versus the corresponding indices at December 31, 2009.

	Percentage Changes December 31,

The fees that we receive for providing investment management and advisory services are primarily driven by the level of AUM. Accordingly, since market movements and foreign currency volatility impact the level of our AUM, such items will impact the level of revenues we receive from our Asset Management business. A substantial portion of our AUM is invested in equities, and market movements reflected in the changes in Lazard’s AUM during the period generally corresponded to the changes in global market indices. Our AUM at December 31, 2011 decreased 9% versus AUM at December 31, 2010 (primarily due to market and foreign exchange depreciation), while our average AUM for 2011 increased 11% as compared to our average AUM in 2010. The higher levels of average AUM contributed to increased management fee revenues in 2011.

Financial Statement Overview

Net Revenue

The majority of Lazard’s Financial Advisory net revenue is earned from the successful completion of M&A transactions, strategic advisory matters, restructuring and capital structure advisory services, capital raising and similar transactions. The main drivers of Financial Advisory net revenue are overall M&A activity, the level of corporate debt defaults and the environment for capital raising activities, particularly in the industries and geographic markets in which Lazard focuses. In some client engagements, often those involving financially distressed companies, revenue is earned in the form of retainers and similar fees that are contractually agreed upon with each client for each assignment and are not necessarily linked to the completion of a transaction. In addition, Lazard also earns fees from providing strategic advice to clients, with such fees not being dependent on a specific transaction, and may also earn fees in connection with public and private securities offerings and for referring opportunities to LFCM Holdings for underwriting, distribution and placement of securities. The referral fees received from LFCM Holdings are generally one-half of the revenue recorded by LFCM Holdings in respect of such activities. Significant fluctuations in Financial Advisory net revenue can occur over the course of any given year, because a significant portion of such net revenue is earned upon the successful completion of a transaction, restructuring or capital raising activity, the timing of which is uncertain and is not subject to Lazard’s control.

Lazard’s Asset Management segment principally includes Lazard Asset Management LLC (together with its subsidiaries, “LAM”), LFG, Edgewater (commencing July 15, 2009) and Lazard Wealth Management. Asset Management net revenue is derived from fees for investment management and advisory services provided to institutional and private clients. As noted above, the main driver of Asset Management net revenue is the level of AUM, which is influenced by the performance of the global equity markets and, to a lesser extent, fixed income markets and Lazard’s investment performance, which impacts its ability to successfully attract and retain assets.

40

As a result, fluctuations (including timing thereof) in financial markets and client asset inflows and outflows have a direct effect on Asset Management net revenue and operating income. Asset Management fees are generally based on the level of AUM measured daily, monthly or quarterly, and an increase or reduction in AUM, due to market price fluctuations, currency fluctuations, net client asset flows or otherwise, will result in a corresponding increase or decrease in management fees. The majority of our investment advisory contracts are generally terminable at any time or on notice of 30 days or less. Institutional and individual clients, and firms with which we have strategic alliances, can terminate their relationship with us, reduce the aggregate amount of AUM or shift their funds to other types of accounts with different rate structures for a number of reasons, including investment performance, changes in prevailing interest rates and financial market performance. In addition, as Lazard’s AUM includes significant amounts of assets that are denominated in currencies other than U.S. Dollars, changes in the value of the U.S. Dollar relative to foreign currencies will impact the value of Lazard’s AUM. Fees vary with the type of assets managed and the vehicle in which they are managed, with higher fees earned on equity assets, alternative investments (such as hedge funds) and private equity investments, and lower fees earned on fixed income and cash management products.

The Company earns performance-based incentive fees on various investment products, including traditional products and alternative investment funds such as hedge funds and private equity funds.

For hedge funds, incentive fees are calculated based on a specified percentage of a fund’s net appreciation, in some cases in excess of established benchmarks or thresholds. The Company records incentive fees on traditional products and hedge funds at the end of the relevant performance measurement period, when potential uncertainties regarding the ultimate realizable amounts have been determined. The incentive fee measurement period is generally an annual period (unless an account terminates during the year), and therefore such incentive fees are usually recorded in the fourth quarter of Lazard’s fiscal year. These incentive fees received at the end of the measurement period are not subject to reversal or payback. Incentive fees on hedge funds generally are subject to loss carryforward provisions in which losses incurred by the hedge funds in any year are applied against certain future period net appreciation before any incentive fees can be earned.

For private equity funds, incentive fees may be earned in the form of a “carried interest” if profits arising from realized investments exceed a specified threshold. Typically, such carried interest is ultimately calculated on a whole-fund basis and, therefore, clawback of carried interests during the life of the fund can occur. As a result, incentive fees earned on our private equity funds are not recognized until potential uncertainties regarding the ultimate realizable amounts have been determined, including any potential for clawback.

Corporate segment net revenue consists primarily of investment gains and losses on the Company’s “seed investments” in LAM equity and fixed income funds and principal investments in equities and alternative asset management funds, investments at LFB and “equity method” investments (including gains and losses on the extinguishment of debt, interest income and interest expense). Corporate net revenue also can fluctuate due to changes in the fair value of investments classified as “trading”, and with respect to “available-for-sale” investments, when realized, or, with respect to “available-for-sale” and “held-to-maturity” investments, when a decline is determined to be other than temporary, as well as due to changes in interest and currency exchange rates and in the levels of cash, investments and indebtedness. During the fourth quarter of 2010, all of LFB’s remaining corporate debt portfolio that had been previously designated as “available-for-sale” was sold, with net realized losses on a pre-tax basis reclassified from “accumulated other comprehensive income (loss), net of tax” (“AOCI”) to “investment gains (losses)”. For the years ended December 31, 2010 and 2009, the Company recorded net investment gains of $13 million and $29 million, respectively, in AOCI. As of December 31, 2010 and subsequent thereto, the Company held no “available-for-sale” or “held-to-maturity” investments.

Although Corporate segment net revenue during 2011 represented (3)% of Lazard’s net revenue, total assets in the Corporate segment represented 56% of Lazard’s consolidated total assets as of December 31, 2011, which is attributable to investments in government bonds and money market funds, fixed income funds, alternative asset management funds and other securities, private equity investments, cash and assets associated with LFB.

41

Operating Expenses

The majority of Lazard’s operating expenses relate to compensation and benefits for managing directors and employees. Our compensation and benefits expense includes (i) salaries and benefits, (ii) amortization of the relevant portion of previously granted deferred incentive compensation awards, including (a) share-based incentive compensation under the Lazard Ltd 2005 Equity Incentive Plan (the “2005 Plan”) and the Lazard Ltd 2008 Incentive Compensation Plan (the “2008 Plan”) and (b) Lazard Fund Interests (see Note 16 of Notes to Consolidated Financial Statements) and (iii) a provision for discretionary or guaranteed bonuses and profit pools. Compensation expense in any given period is dependent on many factors, including general economic and market conditions, our operating and financial performance, staffing levels, competitive pay conditions and the nature of revenues earned, as well as the mix between current and deferred compensation.

We believe that “awarded compensation and benefits expense” and the ratio of “awarded compensation and benefits expense” to “operating revenue,” both non-U.S. GAAP measures, provide the most meaningful basis for comparison of compensation and benefits expense between present, historical and future years. “Awarded compensation and benefits expense” for a given year is calculated using “adjusted compensation and benefits expense,” as modified by the following items:

• We deduct amortization expense recorded for U.S. GAAP purposes in each fiscal year associated with the vesting of deferred incentive compensation awards,

• We add (i) the grant date fair value of the deferred incentive compensation awards granted applicable to the relevant year-end compensation process (e.g. grant date fair value of deferred incentive awards granted in 2012, 2011 and 2010 related to the 2011, 2010 and 2009 year-end compensation processes, respectively) and (ii) investments in people (e.g. “sign-on” bonuses) and other special deferred incentive awards granted throughout the applicable year, with such amounts in (i) and (ii) reduced by an estimate of future forfeitures of such awards, and

• We adjust for year-end foreign exchange fluctuations.

For interim periods we use “adjusted compensation and benefits expense” and the ratio of “adjusted compensation and benefits expense” to “operating revenue,” both non-U.S. GAAP measures, for comparison of compensation and benefits expense between periods. For the calculations with respect to “adjusted compensation and benefits expense” and “awarded compensation and benefits expense” and related ratios to “operating revenue,” see the table under “Consolidated Results of Operations” below.

Lazard’s operating expenses also include “non-compensation expense” (which includes costs for occupancy and equipment, marketing and business development, technology and information services, professional services, fund administration and outsourced services and other expenses), the provision (benefit) pursuant to the tax receivable agreement with LFCM Holdings, amortization of intangible assets related to acquisitions and, in 2010 and 2009, restructuring expense. Amortization of intangible assets relates primarily to the acquisition of Edgewater. Restructuring expense relates to certain staff reductions and realignment of personnel in the first quarters of 2010 and 2009, and includes severance and related benefits expense, the acceleration of unrecognized expense pertaining to restricted stock unit awards denominated in shares of Lazard Ltd Class A common stock (“RSUs”) previously granted to individuals who were terminated and certain other costs related to these initiatives.

Provision for Income Taxes

As a result of its indirect investment in Lazard Group, Lazard Ltd, through certain of its subsidiaries, is subject to U.S. federal income taxes on its portion of Lazard Group’s operating income. Lazard Group primarily operates in the U.S. as a limited liability company that is treated as a partnership for U.S. federal income tax purposes. As a result, Lazard Group’s income pertaining to the limited liability company is not subject to U.S. federal income taxes because taxes associated with such income represent obligations of the individual partners. Outside the U.S., Lazard Group operates principally through corporations and is subject to local income taxes.

42

Income taxes shown on Lazard’s consolidated statements of operations are principally related to non-U.S. entities and to New York City Unincorporated Business Tax (“UBT”) attributable to Lazard’s operations apportioned to New York City.

Noncontrolling Interests

Noncontrolling interests primarily relate to the amount attributable to LAZ-MD Holdings’ ownership interest in the net income of Lazard Group, amounts related to Edgewater, and various LAM-related general partnership interests (“GPs”) in limited partnerships held directly by certain of our LAM managing directors and investment companies which are deemed to be controlled by the Company. See Note 15 of Notes to Consolidated Financial Statements for information regarding the Company’s noncontrolling interests.

Consolidated Results of Operations

Lazard’s consolidated financial statements are presented in U.S. Dollars. Many of our non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. Dollar, generally the currency of the country in which the subsidiaries are domiciled. Such subsidiaries’ assets and liabilities are translated into U.S. Dollars using exchange rates as of the respective balance sheet date, while revenue and expenses are translated at average exchange rates during the respective periods based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary’s functional currency are reported as a component of members’/stockholders’ equity. Foreign currency remeasurement gains and losses on transactions in non-functional currencies are included in the consolidated statements of operations.

During 2010 and 2009, the Company reported certain credits (charges) (the “2010 special items” and the “2009 special items”, respectively, and collectively, the “2010 and 2009 special items”) that significantly impacted operating results for the applicable years. We believe that the impact of the 2010 and 2009 special items should be considered when comparing the results of the years in providing the most meaningful comparison between present, historical and future periods. The impact of such special items on the Company’s consolidated statements of operations (described in more detail in Notes 16 and 18 of Notes to Consolidated Financial Statements) is reflected in the table below.

(b) Revenue related to the consolidation of noncontrolling interests is excluded from operating revenue because the Company has no economic interest in such amount.

(c) Gain on the repurchase of the Company’s subordinated promissory note is excluded from operating revenue because of the non-operating nature of such transaction.

(d) Changes in the fair value of investments held in connection with Lazard Fund Interests and other similar deferred compensation arrangements are excluded from operating revenue because they are equally offset by the change in value of the derivative liability pertaining to such awards, which is recorded within compensation and benefits expense.

(a) Expenses related to the consolidation of noncontrolling interests are excluded because, as is the case with operating revenue, Lazard has no economic interest in such amounts.

(b) Changes in fair value of the derivative compensation liability recorded in connection with Lazard Fund Interests and other similar deferred compensation arrangements are excluded from compensation and benefits expense because such amounts are equally offset by a corresponding change in the fair value of the underlying investments excluded from operating revenue.

(c) Includes base salaries and benefits of $506,490, $453,193 and $422,614 for 2011, 2010 and 2009, respectively, and cash incentive compensation of $372,373, $472,484 and $404,569 for the respective years.

Operating Results

As reflected in the table above, the 2010 and 2009 special items had a significant impact on the Company’s reported operating results for the respective years. Lazard management believes that comparisons between years are most meaningful after excluding the impact of such items.

Year Ended December 31, 2011 versus December 31, 2010

The Company reported net income attributable to Lazard Ltd in both 2011 and 2010 of $175 million. The Company’s results in 2010 were significantly impacted by the 2010 special items, which served to decrease net income attributable to Lazard Ltd by $72 million. Accordingly, excluding the after-tax impact of the 2010 special items, net income attributable to Lazard Ltd in 2011 decreased $72 million, or 29%, as compared to 2010. The changes in the Company’s operating results during these years are described below.

Net revenue decreased by $76 million, or 4%, with operating revenue decreasing by $95 million, or 5%. Fees from investment banking and other advisory activities decreased $135 million, or 12%, reflecting the continued cyclical decline in restructuring activity and the number of corporate debt defaults, as well as a slowdown in overall M&A activity. Restructuring fee revenues in 2011 declined by $96 million, or 33%. M&A and Strategic Advisory fees in 2011 decreased $14 million, or 2%. Money management fees, including incentive fees, increased $47 million, or 6%, primarily due to a $102 million, or 14%, increase in money management fees principally reflecting a $15 billion, or 11%, increase in average AUM for 2011 and a favorable change in the mix of AUM into higher margin equity products, partially offset by a $60 million, or 70%, decline in incentive fees earned. Interest income decreased $6 million, or 30%, due primarily to a shift in asset allocation at LFB (with a corresponding decrease in interest expense). Other revenue increased $11 million, or 17%, primarily due to the

46

pre-tax gain of $18 million related to the repurchase of the Company’s subordinated promissory note, partially offset by a $7 million aggregate decrease in net referral fees for underwriting, foreign exchange gains and commission revenue and net investment losses in 2011 (including losses of $3 million related to our purchase of investments underlying Lazard Fund Interests, which are equally offset by a corresponding reduction in compensation and benefits expense) as compared to net investment gains in 2010. Interest expense decreased $8 million, or 8%, principally reflecting the repurchase of our subordinated promissory note in the third quarter of 2011, as well as reduced interest expense on interest rate swap hedges on investments that were sold in 2010.

Compensation and benefits expense in 2011 was $1.169 billion, as compared to $1.194 billion in 2010. The decrease of $25 million in 2011 was principally due to the costs associated with the 2010 special item included in compensation and benefits expense in 2010. Adjusted compensation and benefits expense (which excludes certain items that management believes allows for improved comparability between years and which is described more thoroughly above) was $1.168 billion in 2011, substantially unchanged when compared to $1.166 billion in 2010. The resulting ratios of adjusted compensation and benefits expense to operating revenue were 62.0% and 58.9% for 2011 and 2010, respectively. The increase in the 2011 ratio reflects increases in base salaries of $53 million, or 11%, and amortization expense for deferred incentive compensation of $49 million, or 20%, which in the aggregate were offset by a decrease in cash incentive compensation of $100 million, or 21%. As described above, when analyzing compensation and benefits expense on a full year basis, we believe that awarded compensation and benefits expense provides the most meaningful basis for comparison of compensation and benefits expense between present, historical and future years. Awarded compensation and benefits expense in 2011 of $1.163 billion decreased $54 million, or 4.5%, when compared to $1.217 billion for 2010, roughly in line with the 4.8% decline in operating revenue, despite significant investments in new hires in both of our businesses. The resulting ratio of awarded compensation and benefits expense to operating revenue was substantially unchanged when comparing 2011 to 2010 at 61.7% and 61.5%, respectively. The grant date fair value of year-end deferred incentive compensation awards for 2011 was $281 million, representing a 4% decrease compared to 2010.

In 2012, we currently anticipate a further increase in amortization expense for deferred incentive compensation of approximately $41 million. While the value of deferred incentive compensation award grants related to the 2011 and 2010 compensation processes were at a lower level than in previous years, the vesting periods associated with award grants related to prior years are uneven, resulting in all of the $41 million of increased amortization expense anticipated in 2012. When assuming a constant level of award grants for 2012, we currently anticipate that amortization expense will revert to a lower level in 2013. In addition, we currently expect to record a charge to compensation and benefits expense in the first quarter of 2012 in the range of $25 to $30 million related to severance costs and benefit payments and the acceleration of unrecognized amortization expense of deferred incentive compensation previously granted to individuals being terminated.

Non-compensation expense in 2011 was $413 million, an increase of $43 million, or 11%, as compared to $370 million in 2010. Non-compensation expense in the fourth quarter of 2011 included aggregate charges of $11 million relating to the Company’s leased facilities in the U.K. and the write-off of the capitalized costs related to the Company’s option to acquire the fund management activities of Lazard Alternative Investment Holdings LLC (“LAI”) (see Notes 14 and 21 of Notes to Consolidated Financial Statements). When excluding such charges, non-compensation expense increased by $32 million, or 9%, primarily reflecting (i) higher costs associated with investments in the business, including technology and related consulting, recruitment fees and, to a lesser extent, occupancy-related costs related to new and amended leases and (ii) increased costs related to a higher level of business activity, including transactional and AUM-based costs within our Asset Management business and travel expenditures in both our Financial Advisory and Asset Management businesses. The ratio of non-compensation expense to operating revenue was 21.9% in 2011 versus 18.7% for 2010. In 2012, as compared to 2011, we expect our occupancy-related costs associated with the amended lease at our Rockefeller Center facility to increase by approximately $11 million.

Amortization of intangible assets in 2011 increased by $4 million, primarily due to increased amortization relating to the Edgewater acquisition.

47

The provision pursuant to the tax receivable agreement in 2011 was $0.4 million, as compared to $2 million for 2010.

Operating income in 2011 was $236 million, a decrease of $8 million, or 3%, as compared to operating income of $244 million in 2010 (with such latter amount including the impact of the 2010 special items) and, as a percentage of net revenue, was 13% in both 2011 and 2010. Excluding the impact of the 2010 special items, operating income in 2011 decreased $111 million, or 32%, as compared to operating income of $347 million in 2010, and, as a percentage of net revenue, was 13%, as compared to 18%, respectively.

The provision for income taxes was $45 million and $49 million in 2011 and 2010, respectively, representing effective tax rates of 19.1% and 20.2% in 2011 and 2010, respectively. When excluding the tax impact of the 2010 special items, the income tax provision would have been $56 million in 2010, representing an effective tax rate of 16.2%.

Net income attributable to noncontrolling interests was $16 million and $19 million in 2011 and 2010, respectively. When excluding the impact of the 2010 special items, net income attributable to noncontrolling interests was $44 million in 2010. The decrease of $28 million principally reflects LAZ-MD Holdings’ reduced ownership interest in Lazard Group in 2011 and, to a lesser extent, a decrease in the noncontrolling interest relating to Edgewater in 2011.

Year Ended December 31, 2010 versus December 31, 2009

The Company reported net income attributable to Lazard Ltd of $175 million in 2010, as compared to a net loss of $130 million in 2009. The Company’s results in these years were adversely affected by the 2010 and the 2009 special items, which served to reduce the net income attributable to Lazard Ltd in 2010 and 2009 by $72 million and $143 million, respectively. Excluding the after-tax impact of the 2010 and 2009 special items, net income attributable to Lazard Ltd in 2010 was $247 million, an increase of $234 million as compared to 2009. The changes in the Company’s operating results during these years are described below.

Net revenue in 2010 increased $375 million, or 24%, as compared to 2009, with operating revenue increasing $361 million, or 22%. Fees from investment banking and other advisory activities increased $149 million, or 16%, including increases of $188 million, or 36%, in M&A and Strategic Advisory fees, as well as higher Capital Markets and Other Advisory fees, primarily from our Private Fund Advisory Group business, with the latter due to an increase in the value and number of fund closings, which in the aggregate was partially offset by a $83 million, or 22%, decline in Restructuring fee revenues reflecting a reduction in restructuring activity as the economy improved and the number of corporate debt defaults declined. Money management fees, including incentive fees, increased $249 million, or 44%, primarily due to a $33 billion, or 32%, increase in average AUM for 2010, the result of market appreciation and net inflows during 2010, a favorable change in the mix of AUM into higher margin equity products and higher incentive fees earned in 2010. Interest income decreased $8 million, or 28%, due primarily to the lower interest rate environment. Other revenue decreased $25 million, or 28%, primarily due to a $17 million, or 59%, decline in underwriting referral fees as a result of a lower level of equity capital markets transactions, and foreign exchange losses, as compared to gains in 2009. Other revenue in 2010 included investment gains of $19 million, as compared to gains of $20 million in 2009. The investment gains in 2010 are net of realized losses of $14 million in connection with the sale in the fourth quarter of LFB’s portfolio, while the gains in 2009 are net of a $13 million write-off of the Company’s investment in warrants of Sapphire Industrials Corp. (“Sapphire”), a special purpose acquisition company sponsored by Lazard. Interest expense decreased $10 million, or 9%, due to the lower interest rate environment and reduced levels of LFB’s customer deposits.

Compensation and benefits expense in 2010 was $1.194 billion, as compared to $1.309 billion in 2009. When excluding the 2010 and 2009 special items, compensation and benefits expense in 2010 increased $7 million, or 1%, which includes an increase in base salaries, the provision for discretionary compensation and

48

profit pools directly related to the increase in operating revenue and was partially offset by a reduction in the amortization of share-based and deferred cash incentive awards. The ratios of adjusted compensation and benefits expense to operating revenue were 58.9% and 71.7% for 2010 and 2009, respectively. Awarded compensation and benefits expense in 2010 of $1.217 billion increased $134 million, or 12%, when compared to the $1.083 billion for 2009, a slower rate than the 22% growth in operating revenue. The increase in awarded compensation and benefits expense reflected a $98 million, or 12%, increase in cash compensation and benefits expense in 2010 and a $41 million, or 15%, increase in the grant date fair value of total deferred incentive compensation awards. The resulting ratios of awarded compensation and benefits expense to operating revenue were 61.5% and 67.0% for 2010 and 2009, respectively.

Non-compensation expense in 2010 was $370 million, an increase of $33 million, or 10%, as compared to $337 million in 2009. Factors contributing to this increase included higher spending on travel and other business development activities, technology and fund administration expenses related to a higher level of business activity and AUM. The ratio of non-compensation expense to operating revenue was 18.7% in 2010 versus 20.8% in 2009.

Amortization of intangible assets in 2010 increased $3 million, primarily due to the Edgewater acquisition in July 2009.

In the first quarters of 2010 and 2009, the Company announced plans to reduce certain staff and realign personnel. As a result, the 2010 and 2009 special items include restructuring charges of $87 million and $63 million, respectively, in connection with severance and benefit payments, the acceleration of unrecognized expense pertaining to share-based incentive compensation previously granted to individuals who were terminated and certain other costs related to the restructuring initiatives.

The provision pursuant to the tax receivable agreement for 2010 was $2 million as compared to a benefit of $1 million for 2009. When excluding the impact of the 2010 special items, the provision in 2010 would have been $11 million, with the increase due to a higher level of taxable income in 2010, with a corresponding increase in the level of tax savings attributable to the amortization of tax basis increases.

Operating income for 2010 was $244 million, as compared to an operating loss of $182 million in the prior year (with such amounts including the impact of the 2010 and 2009 special items) and, as a percentage of net revenue, was 13% in 2010, as compared to (12)% in 2009. Excluding the impact of the 2010 and 2009 special items, operating income in 2010 was $347 million, an increase of $319 million, as compared to operating income of $27 million in 2009, and, as a percentage of net revenue, was 18%, as compared to 2%, respectively.

The provision for income taxes was $49 million and $6 million in 2010 and 2009, respectively, representing effective tax rates of 20.2% and (3.3)% in 2010 and 2009, respectively. When excluding the tax benefits relating to the 2010 and 2009 special items, the income tax provision would have been $56 million in 2010, as compared to $15 million in 2009, representing effective tax rates of 16.2% and 54.8% in 2010 and 2009, respectively. The reduction in the effective tax rate in 2010 was primarily due to a change in the geographic mix of operating income between the respective years.

Net income (loss) attributable to noncontrolling interests in 2010 was $19 million, as compared to $(58) million in 2009, an increase of $77 million as compared to 2009. When excluding the impact of the 2010 and 2009 special items, net income attributable to noncontrolling interests was $44 million in 2010, an increase of $44 million as compared to 2009, with such increase primarily reflecting LAZ-MD Holdings’ ownership interest in the increased net income of Lazard Group, partially offset by a decrease in its ownership interest.

Business Segments

The following is a discussion of net revenue and operating income for the Company’s business segments - Financial Advisory, Asset Management and Corporate. Each segment’s operating expenses include (i) compensation and benefits expenses that are incurred directly in support of the segment and (ii) other operating expenses, which include directly incurred expenses for occupancy and equipment, marketing and business development, technology and information services, professional services, fund administration and outsourcing, and indirect support costs (including compensation and benefits expense and other operating expenses related thereto) for administrative services. Such administrative services include, but are not limited to, accounting, tax, legal, facilities management and senior management activities. Such support costs are allocated to the relevant segments based on various statistical drivers such as headcount, square footage and other factors.

Net revenue trends in Financial Advisory for M&A and Strategic Advisory and Restructuring are generally correlated to the volume of completed industry-wide M&A transactions and restructurings occurring subsequent to corporate debt defaults, respectively. However, deviations from this relationship can occur in any given year for a number of reasons. For instance, our results can diverge from industry-wide activity where there are material variances from the level of industry-wide M&A activity in a particular market where Lazard has significant market share, or regarding the relative number of our advisory engagements with respect to larger-sized transactions, and where we are involved in significant non-public assignments. Certain Lazard client statistics and global industry statistics are set forth below:

(b) Source: Dealogic as of January 16, 2012.

The geographical distribution of Financial Advisory net revenue is set forth below in percentage terms and is based on the Lazard offices that generate Financial Advisory net revenue, which are located in the U.S., Europe (primarily in the U.K., France, Italy, Spain and Germany) and the rest of the world (primarily in Australia) and therefore may not be reflective of the geography in which the clients are located.

Europe		38			37			43
Rest of World		7			5			6
Total		100	%		100	%		100	%

The Company’s managing directors and many of its professionals have significant experience, and many of them are able to use this experience to advise on M&A, strategic advisory matters and restructuring transactions, depending on clients’ needs. This flexibility allows Lazard to better match its professionals with the counter-cyclical business cycles of mergers and acquisitions and restructurings. While Lazard measures revenue by practice area, Lazard does not separately measure the costs or profitability of M&A services as compared to restructuring services. Accordingly, Lazard measures performance in its Financial Advisory segment based on overall segment net revenue and operating income margins.

Financial Advisory Results of Operations

As reflected in the table of operating results of the Financial Advisory segment above, the portion of the 2010 and 2009 special items attributable to the Financial Advisory segment had a significant impact on the segment’s reported operating results for the respective years. Lazard management believes that comparisons between years are most meaningful after excluding the impact of such items.

51

Year Ended December 31, 2011 versus December 31, 2010

Total Strategic Advisory net revenue in 2011, representing fees from M&A, Sovereign, Capital Markets, Private Funds and Other Advisory businesses, decreased $32 million, or 4%, and Restructuring revenue declined $96 million, or 33%, as compared to 2010.

M&A and Strategic Advisory revenue in 2011 decreased $14 million, or 2%. Capital Markets and Other Advisory revenue in 2011 decreased $18 million, or 16%. The decrease in M&A and Strategic Advisory revenue in 2011 was principally due to a general slowdown in activity and resulted in lower average fees per M&A and Strategic Advisory transaction. Our major clients, which in the aggregate represented 25% of our M&A and Strategic Advisory revenue for the year, included Atria Senior Living Group, Clayton Dubilier & Rice, IBM, Landis + Gyr, Parmalat Spa, Progress Energy, Qwest Communications International, Royalty Pharmaceuticals, Smurfit Stone Container and Weather Investments.

The decrease in Capital Markets and Other Advisory revenue in 2011 was primarily attributable to a lower level of closings by Private Fund Advisory.

Restructuring revenue is derived from various activities including bankruptcy assignments, global debt and financing restructurings, distressed asset sales and advice on complex on- and off-balance sheet assignments. The decline in Restructuring revenue was in turn driven by a cyclical decline in global restructuring activity, resulting in a lower number of active assignments in 2011, as compared to the prior year, and a corresponding decrease in completion fees. Notable assignments completed in 2011 included Energy Alloys, Nortel Networks, Station Casinos and Westgate Resorts.

Operating expenses decreased $21 million, or 2%, as compared to 2010. Excluding the impact of the 2010 special item attributable to the Financial Advisory segment, operating expenses were substantially unchanged when compared to 2010. Declines in compensation and benefits expense in 2011 were offset by higher costs principally related to travel and recruiting expenses.

Financial Advisory operating income in 2011 was $62 million, a decrease of $107 million, as compared to operating income of $169 million in 2010 (with such latter amount including the impact of the 2010 special item) and, as a percentage of net revenue, was 6% as compared to 15% in 2010. Excluding the impact of the 2010 special item, operating income in 2011 decreased $126 million, as compared to operating income of $188 million in 2010.

Year Ended December 31, 2010 versus December 31, 2009

Total Strategic Advisory net revenue, representing fees from M&A, Sovereign, Capital Markets, Private Funds and Other Advisory businesses, increased $216 million, or 35%, and Restructuring revenue declined $83 million, or 22%, as compared to 2009.

M&A and Strategic Advisory revenue increased $188 million, or 36%. Capital Markets and Other Advisory revenue increased $28 million, or 33%. The increase in M&A and Strategic Advisory revenue in 2010 was principally due to higher average fees per M&A and Strategic Advisory assignment. Our major clients, which in the aggregate represented 25% of our M&A and Strategic Advisory revenue for the year, included 3G Capital, Abraxis Bioscience, Coca-Cola Enterprises, Continental Airlines, Côte d’Ivoire, Kraft Foods, Marken, Newcrest Mining, Ocarina Trust, Royal Bank of Scotland Group and SSL International.

The increase in Capital Markets and Other Advisory revenue in 2010 primarily reflected increased revenue in our Private Fund Advisory Group, resulting from an increase in the number and value of fund closings, and was partially offset by decreases in underwriting referral fees from public offerings.

The decrease in Restructuring revenue was principally driven by a significant decline in retainer fees due to a decline in the number of active assignments in 2010 as compared to the prior year. Notable assignments completed in 2010 included Alliance Bank Joint Stock Company, BTA Bank JSC, Evraz Group, Extended Stay Hotels and LNR Property.

52

Operating expenses decreased $48 million, or 5%, as compared to 2009. Excluding the impact of the 2010 and 2009 special items attributable to the Financial Advisory segment, operating expenses decreased $19 million, or 2%. The principal contributor to the decrease was a decline in the amortization of share-based and deferred cash incentive compensation awards, which was partially offset by a higher provision for discretionary compensation related to the increase in operating revenue, as well as higher costs related to travel, other business development and technology expenses.

Financial Advisory operating income in 2010 was $169 million, an increase of $181 million, as compared to an operating loss of $12 million in 2009 (with such amounts including the impact of the 2010 and 2009 special items) and, as a percentage of net revenue, was 15% as compared to (1)% in 2009. Excluding the impact of the 2010 and 2009 special items, operating income in 2010 was $188 million, an increase of $151 million, as compared to operating income of $37 million in 2009, and as a percentage of net revenue, was 17%, as compared to 4% in 2009.

	2011		2010		2009
	($ in millions)
Average AUM	$	152,072	$	137,381	$	103,988

Total AUM at December 31, 2011 decreased $14 billion, or 9%, as compared to total AUM of $155 billion at December 31, 2010, primarily due to market depreciation and, to a lesser extent, the negative impact of the stronger U.S. Dollar versus foreign currencies. However, average AUM for the year ended December 31, 2011 was 11% higher than that for 2010. International, Global and U.S. equities represented 20%, 49% and 14% of total AUM at December 31, 2011, versus 21%, 50% and 14% at December 31, 2010.

Total AUM at December 31, 2010 increased $26 billion, or 20%, as compared to total AUM of $129 billion at December 31, 2009, primarily the result of market appreciation (which was generally consistent with the

53

industry as a whole) and net inflows occurring during 2010. Average AUM for the year ended December 31, 2010 was 32% higher than the average AUM for 2009. International, Global and U.S. equities represented 21%, 50% and 14% of total AUM at December 31, 2010, respectively, versus 25%, 45% and 12% of total AUM at December 31, 2009, respectively.

As of December 31, 2011 and December 31, 2010, approximately 90% of our AUM was managed on behalf of institutional clients, including corporations, labor unions, public pension funds, insurance companies and banks, and through sub-advisory relationships, mutual fund sponsors, broker-dealers and registered advisors, and, as of such dates, 10% of our AUM was managed on behalf of individual client relationships, which are principally with family offices and high-net worth individuals.

As of December 31, 2011, AUM denominated in foreign currencies represented approximately 61% of our total AUM, as compared to 63% at December 31, 2010. Foreign denominated AUM declines in value with the strengthening of the U.S. Dollar and increases in value as the U.S. Dollar weakens.

The following is a summary of changes in AUM for the years ended December 31, 2011, 2010 and 2009:

(a) Includes inflows of $27,597, $35,028 and $30,984 and outflows of $28,645, $25,682 and $20,731 for the years ended December 31, 2011, 2010 and 2009, respectively.

(b) Includes AUM and unfunded fee-earnings commitments related to the Edgewater Acquisition, offset by the disposition of private equity AUM related to the sale of Fonds Partenaires Gestion SA, our former private equity business in France.

During the year ended December 31, 2011, inflows were principally in Global Equities and resulted from increased investments in existing accounts, as well as new accounts gained. Outflows in 2011 occurred primarily in Global and International Equities and, to a lesser extent, International and U.S. Fixed Income products.

During the year ended December 31, 2010, inflows were principally in Global Equities and resulted from increased investments in existing accounts, as well as new accounts gained. Outflows in 2010 occurred primarily in Global and International Equities and certain Fixed Income products.

As of February 17, 2012, AUM was $155.7 billion, a $14.7 billion increase since December 31, 2011. The change in AUM was due to market/foreign exchange appreciation of $14.6 billion and net inflows of $0.1 billion. Market appreciation was approximately 10% of AUM since December 31, 2011, which was generally consistent with the increase in global market indices during that period.

Asset Management Results of Operations

As reflected in the table of operating results of the Asset Management segment above, the portion of the 2010 and 2009 special items attributable to the Asset Management segment impacted the segment’s reported operating results for the respective years. Lazard management believes that comparisons between years are most meaningful after excluding the impact of such items.

Year Ended December 31, 2011 versus December 31, 2010

Asset Management net revenue in 2011 increased $48 million, or 6%, as compared to 2010. Management fees increased $102 million, or 14%, as compared to 2010, driven primarily by an 11% increase in average AUM, as well as a favorable change in the mix of AUM into higher margin equity products. Incentive fees, consisting of traditional long-only and alternative investment strategies, decreased $60 million, or 70%, as compared to 2010, principally due to difficult market conditions. Other income increased $6 million, or 12%, as compared to 2010, primarily due to increased interest, commission and custody fee income.

55

Operating expenses in 2011 increased $45 million, or 8%, as compared to 2010. Excluding the impact of the 2010 special item attributable to the Asset Management segment, operating expenses increased $47 million, or 8%. The principal contributors to the increase were higher fees for fund administration and outsourced services and increased business development expenses for travel and market related data due to the increased level of business activity, transactions and average AUM and higher compensation expense.

Asset Management operating income in 2011 was $268 million, an increase of $3 million, as compared to operating income of $265 million in 2010 (with such latter amount including the impact of the 2010 special item) and, as a percentage of net revenue, was 30%, as compared to 31% in 2010. Excluding the impact of the 2010 special item, operating income in 2011 was substantially unchanged from 2010.

Year Ended December 31, 2010 versus December 31, 2009

Asset Management net revenue increased $248 million, or 41%, as compared to 2009. Management fees increased $229 million, or 47%, as compared to 2009, driven by a 32% increase in average AUM, as well as a favorable change in the mix of AUM into higher margin equity products. Incentive fees, consisting of traditional long-only and alternative investment strategies, increased $12 million, or 15%, as compared to 2009. Other revenue increased $7 million, or 19%, as compared to 2009, primarily due to increased investment and commission income.

Operating expenses increased $80 million, or 16%, as compared to 2009. Excluding the impact of the 2010 and 2009 special items attributable to the Asset Management segment, operating expenses increased $85 million, or 17%, primarily due to a higher provision for discretionary compensation and profit pools related to the increase in operating revenue, as well as higher fees for outsourced services related to AUM growth and an increase in the amortization of intangible assets relating to the Edgewater acquisition.

Asset Management operating income was $265 million, an increase of $168 million, as compared to $97 million in 2009 (with such amounts including the impact of the 2010 and 2009 special items) and, as a percentage of net revenue, was 31%, as compared to 16% in 2009. Excluding the impact of the 2010 and 2009 special items, operating income in 2010 was $268 million, an increase of $164 million, as compared to operating income of $104 million in 2009, and, as a percentage of net revenue, was 32%, as compared to 17% in 2009.

Corporate Results of Operations

As reflected in the table of operating results of the Corporate segment above, the 2010 and 2009 special items had a significant impact on the segment’s reported operating results for the respective years. Lazard management believes that comparisons between years are most meaningful after excluding the impact of such items.

Year Ended December 31, 2011 versus December 31, 2010

Net interest expense increased $2 million, or 2%, as compared to 2010.

Other revenue in 2011 increased $6 million, or 36%, and includes a pre-tax gain of $18 million related to Company’s repurchase of its subordinated promissory note, partially offset by investment losses of $12 million.

Operating expenses in 2011 decreased $91 million, principally related to the net impact of the 2010 special items recorded in the Corporate segment. When excluding the 2010 special items, operating expenses in 2011 decreased $10 million, or 23%, primarily due to lower compensation, lower expenses related to secondary offerings in 2010 and a lower provision related to the tax receivable agreement. Such decreases were partially offset by expenses in the fourth quarter of 2011 related to the U.K. lease write-off and the write-off of the capitalized costs related to our option to acquire the fund management activities of LAI.

Year Ended December 31, 2010 versus December 31, 2009

Net interest expense was relatively unchanged as compared to 2009. Other revenue declined $6 million, or 27%, compared to 2009, reflecting foreign exchange losses in 2010 as compared to gains in 2009, and lower investment income. Investment income in 2010 includes realized losses of $14 million in connection with the fourth quarter sale of LFB’s portfolio, as compared to the $13 million write-off in 2009 of the Company’s investment in warrants of Sapphire (see Note 5 of Notes to Consolidated Financial Statements).

Operating expenses decreased $83 million, or 40%, the principal portion of which related to the net impact of the 2010 and 2009 special items recorded in the Corporate segment. When excluding the impact of the 2010 and 2009 special items, operating expenses declined $10 million, or 18%, principally due to a decline in the amortization of share-based and deferred cash incentive compensation awards, which was partially offset by a higher provision in 2010 in discretionary compensation related to the increase in the Company’s operating revenue.

Cash Flows

The Company’s cash flows are influenced by the timing of the receipt of Financial Advisory and Asset Management fees, the timing of distributions to shareholders, payments of incentive compensation to managing directors and employees and purchases of Class A common stock and, in 2011, repurchases of debt. M&A, Strategic Advisory, and Asset Management fees are generally collected within 60 days of billing, while Restructuring fee collections may extend beyond 60 days, particularly those that involve bankruptcies with court-ordered holdbacks. Fees from our Private Fund Advisory Group activities are generally collected over a four-year period from billing and typically include an interest component.

The Company makes cash payments for, or in respect of, a significant portion of its incentive compensation during the first three months of each calendar year with respect to the prior year’s results.

(d) Consists primarily of purchases of shares of Class A common stock and common membership interests from LAZ-MD Holdings, settlements of vested RSUs, Class A common stock dividends and distributions to noncontrolling interest holders and activity relating to borrowings, including, in 2011, the repurchase of the Company’s 3.25% subordinated promissory note.

Liquidity and Capital Resources

The Company’s liquidity and capital resources are derived from operating activities, financing agreements and equity offerings.

Operating Activities

Net revenue, operating income and cash receipts fluctuate significantly between quarters. In the case of Financial Advisory, fee receipts are generally dependent upon the successful completion of client transactions, the occurrence and timing of which is irregular and not subject to Lazard’s control. In the case of Asset Management, incentive fees earned on AUM are generally not earned until the end of the applicable measurement period, which is generally the fourth quarter of Lazard’s fiscal year, with the respective receivable collected in the first quarter of the following year.

58

Liquidity is significantly impacted by cash payments for, or in respect of, incentive compensation, a significant portion of which are made during the first three months of the year. As a consequence, cash on hand generally declines in the beginning of the year and gradually builds over the remainder of the year. We also pay certain tax advances during the year on behalf of our managing directors, which serve to reduce their respective incentive compensation payments. We expect this seasonal pattern of cash flow to continue.

Lazard’s consolidated financial statements are presented in U.S. Dollars. Many of Lazard’s non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. Dollar, generally the currency of the country in which such subsidiaries are domiciled. Such subsidiaries’ assets and liabilities are translated into U.S. Dollars at the respective balance sheet date exchange rates, while revenue and expenses are translated at average exchange rates during the year based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary’s functional currency are reported as a component of members’/stockholders’ equity. Foreign currency remeasurement gains and losses on transactions in non-functional currencies are included on the consolidated statements of operations.

We regularly monitor our liquidity position, including cash levels, credit lines, principal investment commitments, interest and principal payments on debt, capital expenditures, dividend payments, purchases of shares of Class A common stock and Lazard Group common membership interests and matters relating to liquidity and to compliance with regulatory net capital requirements. At December 31, 2011, Lazard had approximately $1.0 billion of cash, with such amount including approximately $351 million held at Lazard’s operations outside the U.S.. Since Lazard provides for U.S. income taxes on substantially all of its unrepatriated foreign earnings, no material amount of additional U.S. income taxes would be recognized upon receipt of dividends or distributions of such earnings from its foreign operations.

We maintain lines of credit in excess of anticipated liquidity requirements. As of December 31, 2011, Lazard had approximately $312 million in unused lines of credit available to it, including a $150 million, three-year, senior revolving credit facility with a group of lenders that matures in April 2013 (the “Credit Facility”) (see “—Financing Activities” below) and unused lines of credit available to LFB of approximately $91 million (at December 31, 2011 exchange rates) and Edgewater of $65 million. In addition, LFB has access to the Eurosystem Covered Bond Purchase Program of the Banque de France.

The Credit Facility contains customary terms and conditions, including limitations on consolidations, mergers, indebtedness and certain payments, as well as financial condition covenants relating to leverage and interest coverage ratios. Lazard Group’s obligations under the Credit Facility may be accelerated upon customary events of default, including non-payment of principal or interest, breaches of covenants, cross-defaults to other material debt, a change in control and specified bankruptcy events.

59

Financing Activities

The table below sets forth our corporate indebtedness as of December 31, 2011 and December 31, 2010. The agreements with respect to this indebtedness are discussed in more detail in our consolidated financial statements and related notes included elsewhere in this Form 10-K.

	Maturity Date	As of December 31,				Increase (Decrease)
		2011		2010
		($ in millions)
Senior Debt:
7.125%	2015	$	528.5	$	528.5	$	–
6.85%	2017		548.4		548.4		–
Subordinated Debt (a):
3.25%	–		–		150.0		(150.0	)
Total Senior and Subordinated Debt		$	1,076.9	$	1,226.9	$	(150.0	)

(a) On July 22, 2011, the Company repurchased its outstanding $150 million, 3.25% subordinated promissory note, at a cost, excluding accrued interest, of $131.8 million. Such repurchase resulted in a pre-tax gain of $18.2 million.

Lazard’s annual cash flow generated from operations historically has been sufficient to enable it to meet its annual obligations. Lazard has not drawn on its Credit Facility and prior revolving credit facility since June 30, 2006. We believe that our cash flows from operating activities, along with the use of our credit lines as needed, should be sufficient for us to fund our current obligations for the next 12 months and beyond.

As long as the lenders’ commitments remain in effect, any loan pursuant to the Credit Facility remains outstanding and unpaid or any other amount is owing to the lending bank group, the Credit Facility includes financial condition covenants that require that Lazard Group not permit (i) its Consolidated Leverage Ratio (as defined in the Credit Facility) for the 12-month period ending on the last day of any fiscal quarter to be greater than 4.00 to 1.00 or (ii) its Consolidated Interest Coverage Ratio (as defined in the Credit Facility) for the 12-month period ending on the last day of any fiscal quarter to be less than 3.00 to 1.00. For the 12-month period ended December 31, 2011 Lazard Group was in compliance with such ratios, with its Consolidated Leverage Ratio being 1.87 to 1.00 and its Consolidated Interest Coverage Ratio being 7.90 to 1.00. In any event, no amounts were outstanding under the Credit Facility as of December 31, 2011.

In addition, the Credit Facility, indenture and supplemental indentures relating to Lazard Group’s senior notes contain certain other covenants (none of which relate to financial condition), events of default and other customary provisions. At December 31, 2011, the Company was in compliance with all of these provisions. We may, to the extent required and subject to restrictions contained in our financing arrangements, use other financing sources, which may cause us to be subject to additional restrictions or covenants.

See Note 13 of Notes to Consolidated Financial Statements for additional information regarding senior and subordinated debt.

Stockholders’ Equity

At December 31, 2011, total stockholders’ equity was $867 million, as compared to $796 million and $523 million at December 31, 2010 and 2009, respectively, including $726 million, $652 million and $355 million attributable to Lazard Ltd on the respective dates. The net activity in stockholders’ equity during the years ended December 31, 2011 and 2010 is reflected in the table below (in millions of dollars):

On January 27, 2010, the Board of Directors of Lazard Ltd authorized, on a cumulative basis, a share repurchase program which permitted the repurchase of up to $200 million in aggregate cost of its Class A common stock and Lazard Group common membership interests through December 31, 2011. In addition, in February 2011 and October 2011, the Board of Directors of Lazard Ltd authorized the repurchase of up to an additional $250 million and $125 million, respectively, in aggregate cost of Lazard Ltd Class A common stock and Lazard Group common membership interests through December 31, 2012 and December 31, 2013, respectively. During the year ended December 31, 2011 the Company repurchased 6,135,189 shares of Class A common stock, at an aggregate cost of $205 million and 19,032 Lazard Group common membership interests at an aggregate cost of $1 million. As of January 1, 2012, $212 million of the current aggregate $375 million share repurchase amount authorized as of such date remained available as follows – $87 million of the $250 million share repurchase amount expiring December 31, 2012, and all of the $125 million share repurchase amount expiring December 31, 2013. Furthermore, under the terms of the 2005 Plan and the 2008 Plan, upon the vesting of RSUs, shares of Class A common stock may be withheld by the Company to cover estimated income taxes.

In addition to the repurchases of Class A common stock and Lazard Group common membership interests described above, during the year ended December 31, 2011, in order, among other reasons, to help neutralize the dilutive effect of our share-based incentive compensation plans, the Company utilized $93 million to satisfy certain employees’ withholding tax obligations on vested RSUs and delivery of restricted Class A common stock in lieu of issuing 2,422,427 shares of Class A common stock directly by Lazard Ltd or by delivery of shares held by Lazard Group.

Regulatory Capital

We actively monitor our regulatory capital base. Our principal subsidiaries are subject to regulatory requirements in their respective jurisdictions to ensure their general financial soundness and liquidity, which require, among other things, that we comply with certain minimum capital requirements, record-keeping, reporting procedures, relationships with customers, experience and training requirements for employees and certain other requirements and procedures. These regulatory requirements may restrict the flow of funds to affiliates. See Note 22 of Notes to Consolidated Financial Statements for further information. These regulations differ in the U.S., the U.K., France and other countries in which we operate. Our capital structure is designed to provide each of our subsidiaries with capital and liquidity consistent with its business and regulatory requirements. For a discussion of regulations relating to us, see “Item 1-Business—Regulation” included in this Form 10-K.

Effect of Inflation

We do not believe inflation will significantly affect our compensation costs as they are substantially variable in nature. However, the rate of inflation may affect certain of our other expenses, such as information technology and occupancy costs. To the extent inflation results in rising interest rates and has other effects upon the securities markets, it may adversely affect our financial position and results of operations by reducing AUM, net revenue or otherwise. See “Risk Factors—Other Business Risks—Difficult market conditions can adversely affect our business in many ways, including by reducing the volume of the transactions involving our Financial Advisory business and reducing the value or performance of the assets we manage in our Asset Management business, which, in each case, could materially reduce our revenue or income and adversely affect our financial position.”

62

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our consolidated financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in conformity with U.S. GAAP. The preparation of Lazard’s consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, Lazard evaluates its estimates, including those related to revenue recognition, compensation liabilities, income taxes, investing activities and goodwill. Lazard bases these estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Lazard believes that the critical accounting policies set forth below comprise the most significant estimates and judgments used in the preparation of its consolidated financial statements.

Revenue Recognition

Lazard generates substantially all of its net revenue from providing Financial Advisory and Asset Management services to clients. Lazard recognizes revenue when the following criteria are met:

• there is persuasive evidence of an arrangement with a client,

• the agreed-upon services have been provided,

• fees are fixed or determinable, and

• collection is probable.

The Company earns performance-based incentive fees on various investment products, including traditional products and alternative investment funds such as hedge funds and private equity funds (see “Financial Statement Overview”).

If, in Lazard’s judgment, collection of a fee is not probable, Lazard will not recognize revenue until the uncertainty is removed. We maintain an allowance for doubtful accounts to provide coverage for estimated losses from our receivables. We determine the adequacy of the allowance by estimating the probability of loss based on management’s analysis of the client’s creditworthiness and specifically reserve against exposures where we determine the receivables are impaired, which may include situations where a fee is in dispute or litigation has commenced.

With respect to fees receivable from Financial Advisory activities, such receivables are generally deemed past due when they are outstanding 60 days from the date of invoice. However, some Financial Advisory transactions include specific contractual payment terms that may vary from one month to four years (as is the case for our Private Fund Advisory fees) following the invoice date or may be subject to court approval (as is the case with restructuring assignments that include bankruptcy proceedings). In such cases, receivables are deemed past due when payment is not received by the agreed-upon contractual date or the court approval date, respectively. Financial Advisory fee receivables past due in excess of 180 days are fully provided for unless there is evidence that the balance is collectible. Asset Management fees are deemed past due and fully provided for when such receivables are outstanding 12 months after the invoice date. Notwithstanding our policy for receivables past due, we specifically reserve against exposures relating to Financial Advisory and Asset Management fees where we determine receivables are impaired.

At December 31, 2011 and 2010, the Company had receivables past due of approximately $23 million and $17 million, respectively, and its allowance for doubtful accounts was $19 million and $15 million at such respective dates.

63

Income Taxes

As part of the process of preparing our consolidated financial statements, we estimate our income taxes for each of our tax-paying entities in each of their respective jurisdictions. In addition to estimating actual current tax liability for these jurisdictions, we also must account for the tax effects of differences between the financial reporting and tax reporting of items, such as deferred revenue, compensation and benefits expense, unrealized gains or losses on investments and depreciation and amortization, as well as intercompany transactions such as revenue sharing, dividends and interest expense. These temporary differences result in deferred tax assets and liabilities. Significant judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and, as discussed below, any valuation allowance recorded against our deferred tax assets.

A deferred tax asset is recognized if it is more likely than not (defined as a likelihood of greater than 50%) that a tax benefit will be accepted by a taxing authority. The measurement of deferred tax assets and liabilities is based upon currently enacted tax rates in the applicable jurisdictions. At December 31, 2011, on a consolidated basis, we recorded deferred tax assets of approximately $1.3 billion.

Subsequent to the recognition of deferred tax assets, we also must continually assess the likelihood that such deferred tax assets will be realized. If we determine that we may not fully derive the benefit from a deferred tax asset, we consider whether it would be appropriate to apply a valuation allowance against the applicable deferred tax asset. In order to determine whether we apply a valuation allowance, we must assess whether it is more likely than not that such asset will be realized, taking into account all available information. The ultimate realization of a deferred tax asset for a particular entity depends, among other things, on the generation of taxable income by such entity in the applicable jurisdiction. Although we have been profitable on a consolidated basis in the last two years, certain of our tax-paying entities have individually experienced pre-tax losses on a cumulative three-year basis primarily due to permanent differences between net income and taxable income at such entities. Considering these losses and the other factors listed below, we have recorded a valuation allowance of approximately $1.1 billion on our deferred tax assets as of December 31, 2011.

We consider multiple possible sources of taxable income when assessing a valuation allowance against a deferred tax asset, including:

• future reversals of existing taxable temporary differences;

• future taxable income exclusive of reversing temporary differences and carryforwards;

• taxable income in prior years; and

• tax-planning strategies.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available information, including the following:

• nature, frequency and severity of any recent losses,

• duration of statutory carryforward periods,

• historical experience with tax attributes expiring unused, and

• near-term and medium-term financial outlook.

The weight we give to any particular item is, in part, dependent upon the degree to which it can be objectively verified. We give greater weight to the recent results of operations of a relevant entity. Pre-tax operating losses on a three year cumulative basis or lack of sustainable profitability are considered significant evidence and will generally outweigh a projection of future taxable income.

64

The table below sets forth our deferred tax assets and liabilities, and the valuation allowance recorded against our deferred tax assets, as of December 31, 2011 and December 31, 2010:

	December 31,
	2011			2010
	($ in thousands)
Deferred Tax Assets:
Basis adjustments (primarily as a result of the separation and recapitalization transactions that occurred during 2005 and from secondary offerings)	$	846,252		$	877,143
Compensation and benefits		196,133			207,080
Net operating loss and tax credit carryforwards		209,781			156,798
Depreciation and amortization		1,519			14,785
Other		25,410			39,316
Gross deferred tax assets		1,279,095			1,295,122
Valuation allowance		(1,145,257	)		(1,165,274	)
Total deferred tax assets (net of valuation allowance)	$	133,838		$	129,848
Deferred Tax Liabilities:
Depreciation and amortization	$	16,240		$	16,469
Compensation and benefits		10,729			20,563
Goodwill		15,031			9,839
Other		41,581			35,201
Total deferred tax liabilities	$	83,581		$	82,072

As mentioned previously, certain of our tax-paying entities have individually experienced losses on cumulative basis over the past several years. If these entities achieve sustainable levels of profitability in the future, we believe there is a reasonable possibility that the valuation allowance recorded against our deferred tax assets at such entities could be reduced significantly. If any valuation allowance reduction were to occur, we would likely have a negative effective tax rate in the period in which such reduction occurs. Included in our deferred tax assets as of December 31, 2011 are approximately $709 million related to certain basis step-ups and approximately $137 million of net operating losses generated by the amortization of such step-up assets. Under our tax receivable agreement, Lazard Group will retain 15% of the actual cash tax savings relating to such assets and will pay 85% of such savings to the former owners of Lazard. As a result, in the event of a reduction of our valuation allowance, we also would recognize a liability relating to the portion expected to be payable under the tax receivable agreement. The creation of this liability could potentially offset a significant amount (but not all) of the income we would otherwise recognize upon a release of the valuation allowance.

If any valuation allowance reduction were to occur, for subsequent periods, our effective tax rate, with all other factors being held constant, would increase and could be significantly higher than our effective tax rate in the period immediately preceding the reduction in the valuation allowance. In such a situation, an increase in our effective tax rate would not impact the amount of cash income taxes we would pay in those periods subsequent to the release of any valuation allowance.

In addition to the discussion above regarding deferred tax assets and associated valuation allowances, other factors affect our provision for income taxes, including changes in the geographic mix of our business, the level of our annual pre-tax income, transfer pricing and intercompany transactions. In addition, our interpretation of complex tax laws may impact our recognition and measurement of current and deferred income taxes. Tax contingencies involve complex issues and often require an extended period of time to resolve. Tax contingencies that are resolved in a manner that is adverse to us could have a material adverse effect on our financial results. See “Risk Factors” for more information on risks related to income taxes.

65

See Note 19 of Notes to Consolidated Financial Statements for additional information regarding income tax matters.

Investments

Investments consist principally of debt securities, equities, interests in alternative asset management funds, fixed income funds and other private equity investments.

These investments are carried at either fair value on the consolidated statements of financial condition, with any increases or decreases in fair value reflected (i) in earnings, to the extent held by our broker-dealer subsidiaries or when designated as “trading” securities within our non-broker-dealer subsidiaries, and (ii) in AOCI, to the extent designated as “available-for-sale” securities until such time they are realized and reclassified to earnings, or, if designated as “held-to-maturity” securities, amortized cost on the consolidated statements of financial condition. Any declines in the fair value of “available-for-sale” and “held-to-maturity” securities that are determined to be other than temporary are charged to earnings. As of December 31, 2010 and subsequent thereto, there were no securities designated as “available-for-sale” or “held-to-maturity”.

Gains and losses on investment positions held, which arise from sales or changes in the fair value of the investments, are not predictable and can cause periodic fluctuations in net income or AOCI and therefore subject Lazard to market and credit risk.

Data relating to net investments is set forth below (in millions of dollars):

	December 31,
	2011 (a)						2010
	$			%			$			%
Debt securities (b)	$	37			10	%		$62			15	%
Equity securities (net of $4 and $3 of securities sold, not yet purchased, at December 31, 2011 and 2010, respectively) (c)		152			41			86			21
Alternative asset management funds owned (principally GP interests in Lazard-managed hedge funds) (d)		20			5			50			12
Private equity owned (e)		104			28			96			23
Fixed income funds (f)		31			8			34			8
Other (g)		30			8			87			21
Net investments	$	374			100	%		$415			100	%
Total assets	$	3,082					$	3,423
Net investments, as a percentage of total assets		12	%					12	%

(a) Investments above include investments held in connection with Lazard Fund Interests and other similar deferred compensation arrangements granted, with an aggregate fair value of $27 million at December 31, 2011. Market risk associated with such investments is equally offset by any changes in the fair value related to the Company’s obligation pertaining to such awards.

(b) Debt securities primarily consist of U.S. and non-U.S. government debt securities and debt securities of U.S. Government agencies and state and municipal debt securities, and include debt securities seeding our Asset Management business.

(c) The Company’s equity securities primarily represent investments in marketable equity securities of large-, mid- and small-cap domestic, international and global companies seeding new Asset Management products and includes investments in public and private asset management funds managed both by LAM and third-party asset managers. Hedging strategies are employed to attempt to reduce market risk, and, in turn, the volatility to earnings.

66

Additional information regarding equity securities is shown below:

	December 31,
	2011			2010
Percentage invested in:
Consumer		38	%		28	%
Financials		19			28
Industrial		9			9
Other		34			35
Total		100	%		100	%

(d) The fair value of such interests reflects the pro-rata value of the ownership of the underlying securities in the funds. Such funds are broadly diversified and may incorporate particular strategies; however, there are no investments in funds with a single sector strategy.

(e) Comprised of investments in private equity funds and direct private equity interests that are generally not subject to short-term market fluctuation, but may subject Lazard to market or credit risk.

Private equity investments primarily include (i) a mezzanine fund, which invests in mezzanine debt of a diversified selection of small-to mid-cap European companies; (ii) CP II, a private equity fund targeting significant noncontrolling investments in established public and private companies; (iii) Senior Housing, which targets controlling interests in companies and assets in senior housing, extended stay and shopping center sectors, and (iv) Edgewater Growth Capital Partners III, a private equity fund primarily making growth equity and buyout investments in high-quality, lower middle market companies.

(f) Fixed income funds primarily consists of amounts seeding products of our Asset Management segment. Hedging strategies are employed to attempt to reduce market risk and, in turn, the volatility to earnings.

(g) Represents investments (i) accounted for under the equity method of accounting and (ii) private equity and general partnership interests that are consolidated but owned by noncontrolling interests, and therefore do not subject the Company to market or credit risk. The applicable noncontrolling interests are presented within “stockholders’ equity” on the consolidated statements of financial condition.

The decrease in the Company’s aggregate investments at December 31, 2011 compared to December 31, 2010 of $41 million relates principally to maturities of government debt securities, the disposition of certain alternative asset management funds and a decline in private equity and general partnership interests consolidated but owned by noncontrolling interests, partially offset by additional investments in corporate equities to seed Asset Management products.

At December 31, 2011, $133 million of our total investments at a fair value of $374 million, or 36%, were classified as Level 3 assets. Substantially all of our Level 3 investments are priced based on a NAV or its equivalent. During the year ended December 31, 2011, approximately $3 million of losses were recognized in “revenue-other” on the consolidated statement of operations pertaining to Level 3 investments. For additional information, see Note 6 of Notes to Consolidated Financial Statements.

For additional information regarding risks associated with our investments, see “Risk Factors—Other Business Risks—Our results of operations may be affected by market fluctuations related to positions held in our investment portfolios”.

See Notes 5 and 6 of Notes to Consolidated Financial Statements for additional information regarding investments and certain other assets and liabilities measured at fair value, including the levels of fair value within which such measurements of fair value fall.

Assets Under Management

AUM managed by LAM and LFG, which represents substantially all of the Company’s total AUM, principally consists of debt and equity instruments whose value is readily available based on quoted prices on a recognized exchange or by a broker. Accordingly, significant estimates and judgments are generally not involved in the calculation of the value of our AUM.

67

Goodwill

In accordance with current accounting guidance, goodwill has an indefinite life and is tested for impairment annually or more frequently if circumstances indicate impairment may have occurred. For years prior to 2011, Lazard made estimates and assumptions in order to determine the fair value of its assets and liabilities and to project future earnings using various valuation techniques. Commencing in 2011, as permitted under an amendment issued by the Financial Accounting Standards Board, the Company elected to perform a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of the reporting unit. See Note 11 of Notes to Consolidated Financial Statements for additional information regarding goodwill.

Consolidation of VIEs

The consolidated financial statements include the accounts of Lazard Group and all other entities in which it has a controlling interest. Lazard determines whether it has a controlling interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”) under U.S. GAAP.

• Voting Interest Entities. Voting interest entities are entities in which (i) the total equity investment at risk is sufficient to enable the entity to finance itself independently and (ii) the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. Lazard is required to consolidate a voting interest entity that it maintains an ownership interest in if it holds a majority of the voting interest in such entity.

• Variable Interest Entities. VIEs are entities that lack one or more of the characteristics of a voting interest entity. If Lazard has a variable interest, or a combination of variable interests in a VIE, it is required to analyze whether it needs to consolidate such VIE.

Lazard is involved with various entities in the normal course of business that are VIEs and holds variable interests in such VIEs. Transactions associated with these entities primarily include investment management, real estate and private equity investments. Those VIEs for which Lazard is determined to be the primary beneficiary are consolidated in accordance with the applicable accounting guidance. Those VIEs include company-sponsored venture capital investment vehicles established in connection with Lazard’s compensation plans.

Risk Management

We encounter risk in the normal course of business, and therefore, in order to help manage and monitor such risks, we have designed risk management processes which consider both the nature of our business and our operating model. We are subject to varying degrees of credit and market risk, including risks related to the level of soundness of our clients, financial, governmental and other institutions and third parties, as well as operational and liquidity risks (see “—Liquidity and Capital Resources”) and we monitor these risks at both an entity level and on a consolidated basis. Management within each of Lazard’s operating locations is principally responsible for managing the risks within its respective businesses on a day-to-day basis.

Market and/or credit risks related to our investing activities are discussed under “Critical Accounting Policies and Estimates—Investments” above. Risks related to Lazard’s other activities are presented below. Lazard has established procedures to assess credit and market risks, as well as specific interest rate and currency risk, and has established limits related to various positions.

Risks Related to Receivables

We maintain an allowance for doubtful accounts to provide coverage for probable losses from our receivables. We determine the adequacy of the allowance by estimating the probability of loss based on our analysis of the client’s creditworthiness and specifically provide for exposures where we determine the receivables are impaired. At December 31, 2011, total receivables amounted to $504 million, net

68

of an allowance for doubtful accounts of $19 million. As of that date, Financial Advisory and Asset Management fees, customer and related party receivables comprised 80%, 16% and 4% of total receivables, respectively. At December 31, 2010, total receivables amounted to $569 million, net of an allowance for doubtful accounts of $15 million. As of that date, Financial Advisory and Asset Management fees, customer and related party receivables comprised 85%, 11% and 4% of total receivables, respectively. See also “Critical Accounting Policies and Estimates—Revenue Recognition” above and Note 4 of Notes to Consolidated Financial Statements for additional information regarding receivables.

LFB engages in lending activities, including commitments to extend credit. At December 31, 2011 and 2010, customer and related party receivables included $29 million and $41 million of LFB loans, respectively. Such loans are closely monitored for counterparty creditworthiness to help minimize exposure. In addition, as of December 31, 2011, LFB had commitments to lend totaling $16 million, which are fully collateralized and generally contain requirements for the counterparty to maintain a minimum collateral level.

LFB fully secures its collateralized lending and borrowing transactions with fixed income securities.

Credit Concentrations

To reduce the exposure to concentrations of credit from banking activities within LFB, the Company has established limits for corporate counterparties and monitors the exposure against such limits. At December 31, 2011, excluding inter-bank counterparties, LFB had no exposure to an individual counterparty that exceeded $22 million, with such amount being fully collateralized.

With respect to activities outside LFB, as of December 31, 2011 the Company’s largest individual counterparty exposure was a Financial Advisory fee receivable of $17 million, the terms of which require payment over a remaining period of 18 months, including accrued interest.

Risks Related to Derivatives

Lazard enters into interest rate swaps and foreign currency exchange contracts to hedge exposures to interest rates and currency exchange rates and uses equity and fixed income swap contracts to hedge a portion of its market exposure with respect to certain equity investments. At December 31, 2011 and 2010, such derivative contracts are recorded at fair value. Derivative assets amounted to $7 million and $2 million at December 31, 2011 and 2010, respectively, and derivative liabilities, excluding the derivative liability arising from the Company’s obligation pertaining to Lazard Fund Interests and other similar deferred compensation arrangements, amounted to $1 million and $3 million at such respective dates.

In addition, LFB may take open foreign exchange positions with a view to profit, but does not sell foreign exchange options in this context, and enters into interest rate swaps, forward foreign exchange contracts and other derivative contracts to hedge exposures to interest rate and currency fluctuations. The primary market risks associated with LFB’s foreign currency exchange hedging and lending activities are sensitivity to changes in the general level of interest rate and foreign exchange risk. The risk management strategies that we employ use various risk sensitivity metrics to measure such risks and to examine behavior under significant adverse market conditions. The following sensitivity metrics provide the resultant effects on the Company’s operating income for the year ended December 31, 2011:

• LFB’s interest rate risk as measured by a 100+/– basis point change in interest rates totaled $600 thousand.

• Foreign currency risk associated with LFB’s open positions, in the aggregate, as measured by a 200+/– basis point change against the U.S. Dollar, totaled approximately $5 thousand.

69

Risks Related to Short-Term Investments and Corporate Indebtedness

A significant portion of the Company’s indebtedness has fixed interest rates, while its cash and short-term investments generally have floating interest rates. Based on account balances as of December 31, 2011, Lazard estimates that its annual operating income relating to cash and short-term investments and corporate indebtedness would increase by approximately $10 million in the event interest rates were to increase by 1% and decrease by approximately $2 million if rates were to decrease by 1%.

As of December 31, 2011, the Company’s cash and cash equivalents totaled approximately $1 billion. Substantially all of the Company’s cash and cash equivalents were invested in highly liquid institutional money market funds (a significant majority of which were invested solely in U.S. Government or agency money market funds) or in short-term interest earning accounts at a number of leading banks throughout the world, or in short-term certificates of deposit from such banks. On a regular basis, management reviews and updates its list of approved depositor banks as well as deposit and investment thresholds.

Operational Risks

Operational risk is inherent in all our business and may, for example, manifest itself in the form of errors, breaches in the system of internal controls, business interruptions, fraud or legal actions due to operating deficiencies or noncompliance. The Company maintains a framework including policies and a system of internal controls designed to monitor and manage operational risk and provide management with timely and accurate information. Management within each of the operating companies is primarily responsible for its operational risk programs. The Company has in place business continuity and disaster recovery programs that manage its capabilities to provide services in the case of a disruption. We purchase insurance programs designed to protect the Company against accidental loss and losses, which may significantly affect our financial objectives, personnel, property or our ability to continue to meet our responsibilities to our various stakeholder groups.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Lazard Ltd and its subsidiaries (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed under the supervision of the Company’s principal executive and principal financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

Our internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of the Company’s management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2011. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on management’s assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2011.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, audited the Company’s internal control over financial reporting as of December 31, 2011, as stated in their report which appears under “Reports of Independent Registered Public Accounting Firm.”

72

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Lazard Ltd:

We have audited the internal control over financial reporting of Lazard Ltd and subsidiaries (the “Company”) as of December 31, 2011 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’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”. 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, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as listed in the Index at Item 8 as of and for the year ended December 31, 2011 of the Company, and our report dated February 28, 2012 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Lazard Ltd:

We have audited the accompanying consolidated statements of financial condition of Lazard Ltd and subsidiaries (the “Company”) as of December 31, 2011 and 2010, and the related consolidated statements of operations, cash flows, and changes in stockholders’ equity, for each of the three years in the period ended December 31, 2011. Our audits also included the financial statement schedule listed in the Index at Item 8. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedule based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Lazard Ltd and subsidiaries at December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2012 expressed an unqualified opinion on the Company’s internal control over financial reporting.

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

Lazard Ltd, a Bermuda holding company, and its subsidiaries (collectively referred to as “Lazard Ltd”, “Lazard”, “we” or the “Company”), including Lazard Ltd’s indirect investment in Lazard Group LLC, a Delaware limited liability company (collectively referred to, together with its subsidiaries, as “Lazard Group”), is one of the world’s preeminent financial advisory and asset management firms and has long specialized in crafting solutions to the complex financial and strategic challenges of our clients. We serve a diverse set of clients around the world, including corporations, partnerships, institutions, governments and high net worth individuals.

Lazard Ltd indirectly held approximately 94.8% and 94.0% of all outstanding Lazard Group common membership interests as of December 31, 2011 and 2010, respectively. Lazard Ltd, through its control of the managing members of Lazard Group, controls Lazard Group. LAZ-MD Holdings LLC (“LAZ-MD Holdings”), an entity owned by Lazard Group’s current and former managing directors, held approximately 5.2% and 6.0% of the outstanding Lazard Group common membership interests as of December 31, 2011 and 2010, respectively. Additionally, LAZ-MD Holdings was the sole owner of the one issued and outstanding share of Lazard Ltd’s Class B common stock (the “Class B common stock”) which provided LAZ-MD Holdings with approximately 5.2% and 6.0% of the voting power but no economic rights in the Company as of December 31, 2011 and 2010, respectively. Subject to certain limitations, LAZ-MD Holdings’ interests in Lazard Group are exchangeable for Lazard Ltd Class A common stock, par value $0.01 per share (“Class A common stock”). Lazard Group is governed by an Operating Agreement dated as of May 10, 2005, as amended (the “Operating Agreement”).

Our sole operating asset is our indirect ownership of common membership interests of Lazard Group and our managing member interest of Lazard Group, whose principal operating activities are included in two business segments:

• Financial Advisory, which offers corporate, partnership, institutional, government, sovereign and individual clients across the globe a wide array of financial advisory services regarding mergers and acquisitions (“M&A”) and other strategic matters, restructurings, capital structure, capital raising and various other financial matters, and

• Asset Management, which includes strategies for the management of equity and fixed income securities and alternative investment and private equity funds, as well as wealth management.

In addition, we record selected other activities in our Corporate segment, including management of cash, certain investments and the commercial banking activities of Lazard Group’s Paris-based Lazard Frères Banque SA (“LFB”). We also allocate outstanding indebtedness to our Corporate segment.

LFB is a registered bank regulated by the Autorité de Contrôle Prudentiel. It is engaged primarily in commercial and private banking services for clients and funds managed by Lazard Frères Gestion SAS (“LFG”) and other clients, investment banking activities, including participation in underwritten offerings of securities in France, asset-liability management and limited trading in securities and foreign exchange.

Basis of Presentation

The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company’s policy is to consolidate (i) entities in which it has a controlling financial interest, (ii) variable interest entities (“VIEs”) where the Company has a

82

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

variable interest and is deemed to be the primary beneficiary and (iii) limited partnerships where the Company is the general partner, unless the presumption of control is overcome. When the Company does not have a controlling interest in an entity, but exerts significant influence over the entity’s operating and financial decisions, the Company applies the equity method of accounting in which it records in earnings its share of earnings or losses of the entity. Intercompany transactions and balances have been eliminated.

The consolidated financial statements include Lazard Ltd, Lazard Group and Lazard Group’s principal operating subsidiaries: Lazard Frères & Co. LLC (“LFNY”), a New York limited liability company, along with its subsidiaries, including Lazard Asset Management LLC and its subsidiaries (collectively referred to as “LAM”); its French limited liability companies Compagnie Financière Lazard Frères SAS (“CFLF”) along with its subsidiaries, LFB and LFG, and Maison Lazard SAS and its subsidiaries; and Lazard & Co., Limited (“LCL”), through Lazard & Co., Holdings Limited, an English private limited company (“LCH”), together with their jointly owned affiliates and subsidiaries.

2. SIGNIFICANT ACCOUNTING POLICIES

The accounting policies below relate to reported amounts and disclosures in the consolidated financial statements.

Foreign Currency Translation—The consolidated financial statements are presented in U.S. Dollars. Many of the Company’s non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. Dollar, generally the currency of the country in which such subsidiaries are domiciled. Such subsidiaries’ assets and liabilities are translated into U.S. Dollars at year-end exchange rates, while revenue and expenses are translated at average exchange rates during the year based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary’s functional currency to U.S. Dollars are reported in “accumulated other comprehensive income (loss), net of tax” (“AOCI”). Foreign currency remeasurement gains and losses on transactions in non-functional currencies are included on the consolidated statements of operations. Net foreign currency remeasurement gains (losses) amounted to $1,406, $(1,606) and $5,700, respectively, for the years ended December 31, 2011, 2010 and 2009, and are included in “revenue-other” on the respective consolidated statements of operations.

Use of Estimates—In preparing the consolidated financial statements, management makes estimates and assumptions regarding:

• valuations of assets and liabilities requiring fair value estimates including, but not limited to, investments, derivatives, securities sold, not yet purchased and assumptions used to value pension and other post-retirement plans;

• the adequacy of the allowance for doubtful accounts;

• the realization of deferred taxes and adequacy of tax reserves for uncertain tax positions;

• the outcome of litigation;

• the carrying amount of goodwill and other intangible assets;

• the amortization period of intangible assets;

• the valuation of shares issued or issuable that contain transfer restrictions;

• share-based and other deferred compensation plan forfeitures, and

• other matters that affect the reported amounts and disclosure of contingencies in the consolidated financial statements.

83

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

Estimates, by their nature, are based on judgment and available information. Therefore, actual results could differ from those estimates and could have a material impact on the consolidated financial statements.

Cash and Cash Equivalents—The Company defines cash equivalents as short-term, highly liquid securities and cash deposits with original maturities of 90 days or less when purchased.

Deposits with Banks—Represents LFB’s short-term deposits, principally with the Banque de France. The level of these deposits may be driven by the level of LFB customer and bank-related interest-bearing time and demand deposits (which can fluctuate significantly on a daily basis) and by changes in asset allocation.

Cash Deposited with Clearing Organizations and Other Segregated Cash—Primarily represents restricted cash deposits made by the Company, including those to satisfy the requirements of clearing organizations.

Allowance for Doubtful Accounts—We maintain an allowance for bad debts to provide for estimated losses relating to fees and customer receivables. We determine the adequacy of the allowance by estimating the probability of loss based on management’s analysis of the client’s creditworthiness and specifically reserve against exposures where we determine the receivables may be impaired, which may include situations where a fee is in dispute or litigation has commenced.

With respect to fees receivable from Financial Advisory activities, such receivables are generally deemed past due when they are outstanding 60 days from the date of invoice. However, some Financial Advisory transactions include specific contractual payment terms that may vary from one month to four years (as is the case for our Private Fund Advisory fees) following the invoice date or may be subject to court approval (as is the case with bankruptcy-related restructuring assignments). In such cases, receivables are deemed past due when payment is not received by the agreed-upon contractual date or the court approval date, respectively. Financial Advisory fee receivables past due in excess of 180 days are fully provided for unless there is evidence that the balance is collectable. Asset Management fees are deemed past due and fully provided for when such receivables are outstanding 12 months after the invoice date. Notwithstanding our policy for receivables past due, we specifically reserve against exposures relating to Financial Advisory and Asset Management fees where we determine receivables are impaired.

See Note 4 of Notes to Consolidated Financial Statements for additional information regarding receivables.

Investments—Investments in debt and marketable equity securities held either directly or indirectly through asset management funds at the Company’s broker-dealer subsidiaries are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard industry practices. Such amounts are reflected in “revenue-other” in the consolidated statements of operations.

Investments in debt and marketable equity securities held at the Company’s non broker-dealer subsidiaries may include “trading”, “available-for-sale” and “held-to-maturity” securities. Investments in debt and marketable equity securities considered “trading” securities are accounted for at fair value, with any increase or decrease in fair value reflected in “revenue-other” in the consolidated statements of operations. Investments in debt securities considered “available-for-sale” securities are accounted for at fair value, with any increase or decrease in fair value reported in AOCI, until such time they are realized and reclassified to earnings. Investments in debt securities considered “held-to-maturity” securities are accounted for at amortized cost. Declines in the fair value of “available-for-sale” and “held-to-maturity” securities that are determined to be other-than-temporary are charged to earnings, which, for periods beginning after April 1, 2009, may only include the credit loss component of such declines. At December 31, 2010 and subsequent thereto, the Company had no “available-for-sale” or “held-to-maturity” debt or marketable equity securities.

84

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

Other investments include general partnership and limited partnership interests in alternative asset management funds, fixed income funds and private equity investments accounted for at fair value, as well as investments accounted for under the equity method of accounting. Any increases or decreases in the carrying value of those investments accounted for at fair value and the Company’s share of net income or losses pertaining to its equity method investments are reflected in “revenue-other” in the consolidated statements of operations.

Dividend income is reflected in “revenue-other” on the consolidated statements of operations. Interest income includes accretion or amortization of any discount or premium arising at acquisition of the related debt security. Securities transactions and the related revenue and expenses are recorded on a “trade date” basis.

See Notes 5 and 6 of Notes to Consolidated Financial Statements for additional information regarding the Company’s investments.

Property-net—Property is stated at cost or, in the case of buildings under capital leases, the present value of the future minimum lease payments, less accumulated depreciation and amortization. Buildings represent owned property and amounts recorded pursuant to capital leases (see Notes 10 and 14 of Notes to Consolidated Financial Statements), with the related obligations recorded as capital lease obligations. Such buildings are depreciated on a straight-line basis over their estimated useful lives. Leasehold improvements are capitalized and are amortized over the lesser of the economic useful life of the improvement or the term of the lease. Depreciation of furniture and equipment, including computer hardware and software, is determined on a straight-line basis using estimated useful lives. Depreciation and amortization expense aggregating $24,580, $22,712 and $22,541 for the years ended December 31, 2011, 2010 and 2009, respectively, is included on the respective consolidated statements of operations in “occupancy and equipment” or “technology and information services”, depending on the nature of the underlying asset. Repairs and maintenance are expensed as incurred.

Goodwill and Other Intangible Assets—As goodwill has an indefinite life, it is required to be tested for impairment annually or more frequently if circumstances indicate impairment may have occurred. For years prior to 2011, the Company assessed whether any goodwill recorded by its applicable reporting units was impaired by comparing the fair value of each reporting unit with its respective carrying amount. In this process, Lazard used its best judgment and information available to it at the time to perform this review and utilized various valuation techniques in order to determine the applicable fair values. Commencing in 2011, as permitted under an amendment issued by the Financial Accounting Standards Board (the “FASB”), the Company elected to perform a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of the reporting unit.

Intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. This analysis is performed by comparing the carrying value of the intangible asset being reviewed for impairment to the current and expected future cash flows expected to be generated from such asset on an undiscounted basis, including eventual disposition. An impairment loss would be measured for the amount by which the carrying amount of the intangible asset exceeds its fair value.

See Note 11 of Notes to Consolidated Financial Statements with respect to goodwill and other intangible assets.

Derivative Instruments—A derivative is typically defined as an instrument whose value is “derived” from underlying assets, indices or reference rates, such as a future, forward, swap, or option contract, or other financial

85

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

instrument with similar characteristics. Derivative contracts often involve future commitments to exchange interest payment streams or currencies based on a notional or contractual amount (e.g., interest rate swaps or currency forwards) or to purchase or sell other financial instruments at specified terms on a specified date (e.g., options to buy or sell securities or currencies).

The Company enters into forward foreign currency exchange rate contracts, interest rate swaps, interest rate futures, equity and fixed income swaps and other derivative contracts to hedge exposures to fluctuations in currency exchange rates, interest rates and equity and debt markets. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company’s derivative instruments are recorded at their fair value, and are included in “other assets” and “other liabilities” on the consolidated statements of financial condition. Except for derivative instruments hedging its then “available-for-sale” securities held prior to 2011 (see Note 5 of Notes to Consolidated Financial Statements), the Company elected not to apply hedge accounting to its other derivative instruments. Gains and losses on the Company’s derivative contracts not designated as hedging instruments, as well as gains and losses on derivative instruments accounted for as fair value hedges, are included in “interest income” and “interest expense”, respectively, or “revenue-other”, depending on the nature of the underlying item, on the consolidated statements of operations. Furthermore, with respect to derivative instruments designated as fair value hedges, the hedged item is required to be adjusted for changes in fair value of the risk being hedged, with such adjustment accounted for in the consolidated statements of operations.

In addition to the derivative instruments above, the Company recognized a derivative liability relating to its obligation pertaining to Lazard Fund Interests awards (“Lazard Fund Interests”) and other similar deferred compensation arrangements, the fair value of which is based on the value of the underlying investments and is included in “accrued compensation and benefits” on the consolidated statement of financial condition as of December 31, 2011. Changes in the fair value of the derivative liability are included in “compensation and benefits” on the consolidated statement of operations for the year ended December 31, 2011, the impact of which equally offsets the changes in the fair value of the underlying investments owned and is reported in “revenue-other” in the consolidated statement of operations. For information regarding Lazard Fund Interests and other similar deferred compensation arrangements, see Notes 7 and 16 of Notes to Consolidated Financial Statements.

Deposits and Other Customer Payables—Principally relates to LFB customer-related demand and time deposits, both interest-bearing and non-interest bearing, short-term inter-bank borrowings and amounts due on short-term collateralized borrowing activities. Collateralized borrowing activities amounted to $8,928 and $7,483 at December 31, 2011 and 2010, respectively, and were fully collateralized with pledged assets of equal or greater value at each such date.

Securities Sold, Not Yet Purchased—Securities sold, not yet purchased represents liabilities for securities sold for which payment has been received and the obligations to deliver such securities are included within “other liabilities” in the consolidated statements of financial condition. These securities are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard securities industry practices. Such gains and losses are reflected in “revenue-other” in the consolidated statements of operations.

Fair Value of Financial Assets and Liabilities—The majority of the Company’s financial assets and liabilities are recorded at fair value or at amounts that approximate fair value. Such assets and liabilities include cash and cash equivalents, deposits with banks, cash deposited with clearing organizations and other segregated cash, receivables, investments (excluding investments accounted for at amortized cost, interest-bearing deposits or using the equity

(dollars in thousands, except for per share data, unless otherwise noted)

method of accounting), derivative instruments and deposits and other customer payables. For information regarding the fair value of the Company’s senior and subordinated debt, see Note 13 of Notes to Consolidated Financial Statements.

Revenue Recognition

Investment Banking and Other Advisory Fees—Fees for M&A and Strategic Advisory services and Restructuring advisory services are recorded when earned, which is generally the date the related transactions are consummated. Expenses that are directly related to such transactions and billable to clients are deferred to match revenue recognition. “Investment banking and other advisory fees” on the Company’s consolidated statements of operations are presented net of client reimbursements of expenses. The amount of expenses reimbursed by clients for the years ended December 31, 2011, 2010 and 2009 are $18,942, $20,216 and $21,673, respectively.

Money Management and Incentive Fees—Money management fees are derived from fees for investment management and advisory services provided to institutional and private clients. Revenue is recorded on an accrual basis primarily based on a percentage of client assets managed. Fees vary with the type of assets managed, with higher fees earned on equity assets, alternative investment (such as hedge funds) and private equity products, and lower fees earned on fixed income and money market products.

The Company may earn performance-based incentive fees on various investment products, including alternative investment funds such as hedge funds, private equity funds and traditional investment strategies. Incentive fees are calculated based on a specified percentage of a fund’s net appreciation, in some cases in excess of established benchmarks. Incentive fees on private equity funds also may be earned in the form of a carried interest if profits from investments exceed a specified threshold. These incentive fees are recorded when realized and are paid at the end of the measurement period. Incentive fees on hedge funds generally are subject to loss carry-forward provisions in which losses incurred by the funds in any year are applied against certain future period net appreciation before any incentive fees can be earned.

The Company records incentive fees at the end of the relevant performance measurement period, when potential uncertainties regarding the ultimate realizable amounts have been determined. The performance fee measurement period is generally an annual period, unless an account terminates during the year. These incentive fees received at the end of the measurement period are not subject to reversal or payback.

Receivables relating to money management and incentive fees are reported in “fees receivable” on the consolidated statements of financial condition.

Soft Dollar Arrangements—The Company’s Asset Management business obtains research and other services through “soft dollar” arrangements. Consistent with the “soft dollar” safe harbor established by Section 28(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Asset Management business does not have any contractual obligation or arrangement requiring it to pay for research and other services obtained through soft dollar arrangements with brokers. Instead, the provider is obligated to pay for the services. Consequently, the Company does not incur any liability and does not accrue any expenses in connection with any research or other services obtained by the Asset Management business pursuant to such soft dollar arrangements. If the use of soft dollars is limited or prohibited in the future by regulation, we may have to bear the costs of such research and other services.

Share-Based Incentive Compensation Awards—Share-based incentive compensation awards that do not require future service are expensed immediately; however, awards that require future service are amortized over the applicable vesting period or requisite service period. Expense relating to share-based incentive compensation awards is generally

87

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

based on the fair value of the Company’s Class A common stock on the date of grant, and is recognized in “compensation and benefits” (and, as applicable, in “restructuring” expense, with respect to the expense associated with the acceleration of unrecognized expense pertaining to awards granted previously to individuals who were terminated by the Company in the restructuring programs described in Note 18 of Notes to Consolidated Financial Statements).

Income Taxes—Lazard Ltd, through certain of its subsidiaries, is subject to U.S. corporate federal income tax on its allocable share of the results of operations of Lazard Group, and certain non-U.S. subsidiaries of the Company are subject to income taxes in their local jurisdictions. In addition, the Company is subject to New York City Unincorporated Business Taxes (“UBT”) attributable to Lazard Group’s operations apportioned to New York City.

Substantially all of Lazard’s operations outside the U.S. are conducted in “pass-through” entities for U.S. income tax purposes and the Company provides for U.S. income taxes on a current basis for substantially all of those earnings. The repatriation of prior year earnings attributable to “non-pass-through” entities would not result in the recognition of a material amount of additional U.S. income taxes.

Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. Such temporary differences are reflected as deferred tax assets and liabilities and are included in “other assets” and “other liabilities”, respectively, on the consolidated statements of financial condition.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized and, when necessary, a valuation allowance is established. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. Management considers the following possible sources of taxable income when assessing the realization of deferred tax assets:

• future reversals of existing taxable temporary differences;

• future taxable income exclusive of reversing temporary differences and carryforwards;

• taxable income in prior carryback years; and

• tax-planning strategies.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence, including, but not limited to, the following:

• nature, frequency, and severity of any recent losses;

• duration of statutory carryforward periods;

• historical experience with tax attributes expiring unused; and

• near- and medium-term financial outlook.

Furthermore, management applies the “more likely than not” criteria prior to the recognition of a financial statement benefit of a tax position taken or expected to be taken in a tax return with respect to uncertainty in income taxes.

The Company recognizes interest and/or penalties related to income tax matters in “income tax expense”. See Note 19 of Notes to Consolidated Financial Statements for additional information relating to income taxes.

3. RECENT ACCOUNTING DEVELOPMENTS

Fair Value Measurements—During May 2011, the FASB amended its fair value measurement guidance, which it states was designed to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards (“IFRS”). Although many of the changes for U.S. GAAP purposes are clarifications of existing guidance or wording changes to align with IFRS, additional disclosures about fair value measurements would be required, including (i) a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, (ii) the valuation processes used and the sensitivity of fair value measurements related to investments categorized within Level 3 of the hierarchy of fair value measurements to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any, and (iii) the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial condition but for which the fair value is required to be disclosed. The amended fair value measurement guidance will become effective for interim and annual periods beginning after December 15, 2011 and is to be applied prospectively. Early application is not permitted. The Company does not anticipate that the adoption of the amended fair value measurement guidance will have a material impact on the Company’s consolidated financial statements.

Other Comprehensive Income—During June 2011, the FASB amended its guidance regarding the presentation of comprehensive income, which it states was designed to improve comparability, consistency and transparency. The amendment requires that all changes in comprehensive income be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the one-statement approach, the Company would present total net income, including its components, followed by other comprehensive income, including its components, and a total of comprehensive income. In the two-statement approach, the first statement would present total net income and its components as currently presented by the Company in its consolidated statement of operations, followed consecutively by a second statement that would present the components of other comprehensive income, total other comprehensive income and the total of comprehensive income. The amendment is to be applied retrospectively and is effective with interim and annual periods beginning after December 15, 2011, with early adoption permitted. The Company will adopt the amendment in the first quarter of 2012.

Goodwill—During September 2011, the FASB amended its guidance regarding goodwill impairment testing by allowing an entity the option to make a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of a reporting unit. The amendment became effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption was permitted. The Company adopted the amendment during the year ended December 31, 2011. The adoption of the amended guidance did not have a material impact on the Company’s consolidated financial statements.

Offsetting of Assets and Liabilities—During December 2011, the FASB issued new disclosure requirements regarding the nature of an entity’s rights of setoff and related arrangements associated with its derivative and other financial instruments. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods therein, with retrospective application required. The new disclosures are designed to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under IFRS. The Company does not anticipate that the adoption of the new disclosure requirements will have a material impact on the Company’s consolidated financial statements.

4. RECEIVABLES - NET

The Company’s “receivables - net” represents receivables from fees, customers and other and related parties.

89

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

In connection with short-term collateralized lending activities of LFB, the Company typically receives a pledge of specifically identified securities of equal or greater value than the amount of the cash loaned and that are permitted to be sold or repledged. Collateralized customer loan receivables, which amounted to $5,952 and $4,009 at December 31, 2011 and 2010, respectively, were collateralized by securities of equal or greater value at each such date, none of which were sold or repledged at each such date.

Receivables are stated net of an estimated allowance for doubtful accounts of $19,450 and $15,017 at December 31, 2011 and 2010, respectively, for past due amounts and for specific accounts deemed uncollectible, which may include situations where a fee is in dispute. The Company recorded bad debt expense of $7,952, $8,392 and $4,509 for the years ended December 31, 2011, 2010 and 2009, respectively. In addition, the Company recorded charge-offs, foreign currency translation and other adjustments, which resulted in a net decrease to the allowance for doubtful accounts of $3,519, $4,950 and $8,817 for the years ended December 31, 2011, 2010 and 2009, respectively. At December 31, 2011 and 2010, the Company had receivables deemed past due or uncollectible of $22,785 and $17,101, respectively.

(dollars in thousands, except for per share data, unless otherwise noted)

During the year ended December 31, 2010, the Company sold “available-for-sale” debt securities for $214,540, which equaled its then carrying value, and sold “held-to-maturity” U.S. government and agency debt securities for $132,209, which had a carrying value of $126,573. Accordingly, there are no “available-for-sale” or “held-to-maturity” securities at December 31, 2010 and subsequent thereto.

During the year ended December 31, 2009, an other-than-temporary impairment charge of $1,825 pertaining to “available-for-sale” debt securities was recognized in “other-revenue” on the consolidated statement of operations, representing the credit loss component of debt securities whose fair value was below amortized cost. There were no other-than-temporary impairment charges recognized during the year ended December 31, 2010.

The Company’s debt securities included in the table above are categorized as “trading” securities. Non-U.S. Government and other debt includes U.S. state and municipal debt securities, as well as amounts seeding products of our Asset Management business.

Equities primarily represent the Company’s investments in marketable equity securities of large-, mid- and small-cap domestic, international and global companies seeding new Asset Management products and includes investments in public and private asset management funds managed both by LAM and third-party asset managers.

Interests in alternative asset management funds represent (i) general partner (“GP”) interests owned by Lazard in various Lazard-managed alternative asset management funds and (ii) GP interests consolidated by the Company pertaining to noncontrolling interests in such alternative asset management funds, the latter of which aggregated $777 and $8,219 at December 31, 2011 and 2010, respectively. Such noncontrolling interests, which represent GP interests held directly by certain of our Asset Management managing directors or employees of the Company, are deemed to be controlled by, and therefore consolidated by, the Company in accordance with U.S. GAAP. Noncontrolling interests are presented within “stockholders’ equity” on the consolidated statements of financial condition (see Note 15 of Notes to Consolidated Financial Statements).

Fixed income funds primarily consist of amounts seeding products of our Asset Management business.

Private equity investments include those owned by Lazard and those consolidated but not owned by Lazard. Private equity investments owned by Lazard are primarily comprised of investments in private equity funds and direct private equity interests. Such investments primarily include (i) a mezzanine fund, which invests in mezzanine debt of a diversified selection of small- to mid-cap European companies, (ii) Corporate Partners II Limited (“CP II”), a private equity fund targeting significant noncontrolling-stake investments in established public and private companies, (iii) Lazard Senior Housing Partners LP (“Senior Housing”), which targets controlling interests in companies and assets in the senior housing, extended-stay hotel and shopping center sectors and (iv) Edgewater Growth Capital Partners III, L.P. (“EGCP III”), a private equity fund primarily making equity and buyout investments in lower middle market companies.

Private equity investments consolidated but not owned by Lazard relate to the economic interests that are owned by the leadership team and other investors in the Edgewater Funds (“Edgewater”) which aggregated $18,502 and $67,206 at December 31, 2011 and 2010, respectively (see Note 9 of Notes to Consolidated Financial Statements).

On January 24, 2008, Sapphire Industrials Corp. (“Sapphire”), a then newly-organized special purpose acquisition company formed by the Company, completed an initial public offering (the “Sapphire IPO”). Sapphire had been included in equity method investments prior to its dissolution discussed below. Sapphire was formed for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

the purpose of effecting a business combination within a 24-month period (the “Business Combination”) and net proceeds from the Sapphire IPO were placed in a trust account by Sapphire (the “Trust Account”) pending consummation of the Business Combination. In connection with the Sapphire IPO, the Company purchased warrants from Sapphire for a total purchase price of $12,500 and Sapphire common stock for an aggregate purchase price of $50,000. The Company’s investment in Sapphire had been accounted for using the equity method of accounting. On January 6, 2010, Sapphire announced it had not completed the Business Combination and it would dissolve and distribute the funds in the Trust Account to all of its public shareholders, to the extent they were holders of shares issued in the Sapphire IPO. Pursuant to such dissolution, on January 26, 2010, Sapphire made an initial distribution to the Company aggregating $50,319. All Sapphire warrants expired without value. During the fourth quarter of 2009, the Company recognized a loss of approximately $13,000 principally related to its investment in warrants of Sapphire, with such loss being recorded in “revenue-other” in the accompanying consolidated statement of operations.

The Company recognized gross investment gains and losses for the years ended December 31, 2011, 2010 and 2009, including a gain of $5,636 from the sale of “held-to-maturity” securities during the fourth quarter of 2010, in “revenue-other” on its consolidated statements of operations as follows:

	Year Ended December 31,
	2011		2010		2009
Gross investment gains	$	14,632	$	45,503	$	53,319
Gross investment losses	$	22,376	$	19,703	$	19,740

The table above includes gross unrealized investment gains and losses pertaining to “trading” securities as follows:
	Year Ended December 31,
	2011		2010		2009
Gross unrealized investment gains	$	683	$	78	$	3,723
Gross unrealized investment losses	$	1,135	$	512	$	–

Within AOCI, the Company recorded a reduction in net unrealized losses of $17,923 and $46,273 during the years ended December 31, 2010 and 2009, respectively, pertaining to “available-for-sale” debt securities. The reduction in net unrealized losses during the year ended December 31, 2010 includes the reclassification to earnings of realized gains of $1,755 and realized losses of $16,245 from the sale of the “available-for-sale” portfolio. With respect to adjustments for items reclassified to earnings, the average cost basis is utilized for purposes of calculating realized investment gains and losses.

6. FAIR VALUE MEASUREMENTS

Lazard categorizes its investments and certain other assets and liabilities recorded at fair value into a three-level fair value hierarchy as follows:

Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that Lazard has the ability to access.

Level 2. Assets and liabilities whose values are based on quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in non-active markets or assets valued based

92

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

on net assets value (“NAV”, or its equivalent) redeemable at the measurement date or within the near term without redemption restrictions, or inputs other than quoted prices that are directly observable or derived principally from, or corroborated by, market data.

Level 3. Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. Items included in Level 3 include securities or other financial assets whose volume and level of activity have significantly decreased when compared with normal market activity and there is no longer sufficient frequency or volume to provide pricing information on an ongoing basis as well as assets valued based on NAV not redeemable within the near term.

The Company’s investments in U.S. Government and agency debt securities as well as in non-U.S. Government and other debt securities are considered Level 1 assets when their respective fair values are based on unadjusted quoted prices in active markets and are considered Level 2 assets when their fair values are primarily based on broker quotes as provided by external pricing services.

The fair value of equities is principally classified as Level 1, Level 2 or Level 3 as follows: marketable equity securities are classified as Level 1 and are valued based on the last trade price on the primary exchange for that security; public asset management funds are classified as Level 1 and are valued based on the reported closing price for the fund; investments in private asset management funds are classified as Level 2 and are primarily valued based on information provided by fund managers and, secondarily, from external pricing services to the extent managed by LAM; and Level 3 represents equities valued based on NAV and are not redeemable within the near term.

The fair value of interests in alternative asset management funds is classified as either Level 2 or Level 3 depending on the time frame of any applicable redemption restriction, and is based on information provided by external pricing services.

The Company’s investments in fixed income funds are considered Level 1 assets when the fair values are based on the reported closing price for the fund or Level 2 assets when their fair values are primarily based on broker quotes as provided by external pricing services.

The fair value of private equity investments is classified as Level 3, and is primarily based on NAV and are not redeemable within the near term.

The fair values of derivatives entered into by the Company are classified as Level 2 and are based on the values of the related underlying assets, indices or reference rates as follows - the fair value of forward foreign currency exchange rate contracts is a function of the spot rate and the interest rate differential of the currency from the trade date to settlement date; the fair value of equity and fixed income swaps is based on the change in fair values of the related underlying equity security, financial instrument or index and a specified notional holding; and the fair values of interest rate swaps are based on the interest rate yield curve.

Where information reported is based on broker quotes, the Company generally obtains one quote/price per instrument. In some cases, quotes related to corporate bonds obtained through external pricing services represent the average of several broker quotes. Where information reported is based on data received from fund managers or from external pricing services, the Company reviews such information to ascertain at which level within the fair value hierarchy to classify the investment.

These losses were substantially offset by gains recognized on the hedged risk portion of such “available-for-sale” securities.

8. LAM MERGER TRANSACTION

On September 25, 2008, the Company, LAM and LAZ Sub I, LLC, a then newly-formed subsidiary of LFNY, completed the merger of LAZ Sub I, LLC with and into LAM (the “LAM Merger”). Prior to the LAM Merger, the common equity interests of LAM were held by LFNY, and certain other equity interests of LAM, representing contingent payments should certain specified fundamental transactions occur, were held by present and former employees of LAM. Following the LAM Merger, all equity interests of LAM are owned directly or indirectly by LFNY.

The aggregate non-contingent consideration relating to the equity interests of LAM held by present and former employees of LAM and its subsidiaries (the “Transaction Consideration”) consisted of (i) cash payments made from the closing of the LAM Merger through January 2, 2009 of approximately $60,000, (ii) a cash payment made on October 31, 2011 of approximately $90,000, (iii) the delivery on October 31, 2011 of 2,210,520 shares of Class A common stock and (iv) the satisfaction of certain employees’ tax obligations in lieu of delivering 68,384 shares of Class A common stock on October 31, 2011.

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

additional issuances of 24,537 shares of Class A common stock are subject to delayed payment/issuance until the eighth anniversary of the closing of the LAM Merger because the applicable employees were no longer employed by Lazard or its affiliates on October 31, 2011, subject to certain exceptions. The related liabilities for the present value of the unpaid cash consideration as of December 31, 2010 were recorded in the accompanying consolidated statement of financial condition in “accrued compensation and benefits” and “other liabilities”, and amounted to $15,152 and $71,394, respectively.

9. BUSINESS ACQUISITIONS

On July 15, 2009, the Company established a private equity business with Edgewater. Edgewater manages funds primarily focused on buy-out and growth equity investments in middle market companies. The acquisition was structured as a purchase by Lazard Group of interests in a holding company that in turn owns interests in the general partner and management company entities of the current Edgewater private equity funds (the “Edgewater Acquisition”). Following the Edgewater Acquisition, Edgewater’s leadership team retained a substantial economic interest in such entities.

The aggregate fair value of the consideration recognized by the Company at the acquisition date was $61,624. Such consideration consisted of (i) a one-time cash payment, (ii) 1,142,857 shares of Class A common stock (the “Initial Shares”) and (iii) up to 1,142,857 additional shares of Class A common stock subject to earnout criteria and payable over time (the “Earnout Shares”). The Initial Shares are subject to forfeiture provisions that lapse only upon the achievement of certain performance thresholds and transfer restrictions during the four year period ending December 2014. The Earnout Shares will be issued only if certain performance thresholds are met. On December 30, 2011, 285,715 Initial Shares and 57,287 Earnout Shares became unrestricted or were otherwise delivered.

The Edgewater Acquisition was accounted for under the acquisition method of accounting, whereby the results of the acquired business are included in our consolidated financial results from July 15, 2009, the effective date of the acquisition. As a result of the acquisition, we recorded net tangible assets, identifiable intangible assets and goodwill of $53,635 (consisting primarily of Edgewater’s investments in the underlying funds and cash), $56,200 and $61,630, respectively, which include amounts for Edgewater’s noncontrolling interests held (whose economic interests approximate 50%) aggregating $109,841. Goodwill pertaining to this acquisition is deductible for income tax purposes. See Note 11 of Notes to Consolidated Financial Statements for additional information relating to goodwill and other intangible assets. The operating results relating to Edgewater are included in the Company’s Asset Management segment.

In prior years, the Company made certain other business acquisitions. These purchases were affected through an exchange of a combination of cash, Class A common stock, and by Lazard Ltd issuing shares of non-participating convertible Series A and Series B preferred stock, which are or were each convertible into Class A common stock. In connection with such acquisitions, as of December 31, 2011 and 2010, 47,474 and 1,295,029 shares of Class A common stock, respectively, were issuable on a non-contingent basis. Additionally, at December 31, 2010, 4,862 shares of Series A preferred stock were convertible into shares of Class A common stock on a non-contingent basis. During the year ended December 31, 2011, an additional 9,238 shares of Series A preferred stock became convertible, with the total of 14,100 shares of Series A preferred stock converting into 2,434,561 shares of Class A common stock during the year. Depending upon the future performance of such businesses acquired, at December 31, 2011 and 2010, 7,921 and 17,159 shares of Series A preferred stock were contingently convertible into shares of Class A common stock. See Note 15 of Notes to Consolidated Financial Statements for additional information relating to preferred stock.

Total								$	1,076,850	$	1,076,850

(a) During the year ended December 31, 2010, the Company repurchased $10,000 principal amount of the 7.125% Senior Notes, at a cost, excluding accrued interest, of $10,375, and, after the write-off of applicable unamortized debt issuance costs of $49, the Company recognized a pre-tax loss of $424. In connection with the issuance of the 7.125% Senior Notes, on April 1, 2005, Lazard Group entered into an interest rate forward agreement. On May 9, 2005, Lazard Group settled the interest rate forward agreement, of which $11,003 was deemed to be the effective portion of the hedge and recorded within AOCI and is being amortized as a charge to interest expense over the ten-year term of the 7.125% Senior Notes.

(b) During the year ended December 31, 2009, the Company repurchased $900 principal amount of the 6.85% Senior Notes, at a cost, excluding accrued interest, of $635, and, after the write-off of applicable unamortized debt issuance costs of $7, the Company recognized a pre-tax gain of $258.

(c) On April 29, 2010, Lazard Group entered into a $150,000, three-year senior revolving credit facility with a group of lenders (the “Credit Facility”). The Credit Facility, as amended, replaced the prior revolving credit facility, which was terminated as a condition to effectiveness of the Credit Facility. Interest rates under the Credit Facility vary and are based on either a Federal Funds rate or a Eurodollar rate, in each case plus an applicable margin. As of December 31, 2011, the annual interest rate for a loan accruing interest (based on the Federal Funds overnight rate), including the applicable margin, was 1.90%. At December 31, 2011 and 2010, no amounts were outstanding under the Credit Facility.

The Credit Facility contains customary terms and conditions, including certain financial covenants. In addition, the Credit Facility, the indenture and the supplemental indentures relating to Lazard Group’s senior

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

notes, contain certain covenants, events of default and other customary provisions, including a customary make-whole provision in the event of early redemption where applicable. As of December 31, 2011, the Company was in compliance with all of these provisions. All of the Company’s senior debt obligations are unsecured.

As of December 31, 2011, the Company had approximately $312,000 in unused lines of credit available to it, including the Credit Facility, and unused lines of credit available to LFB of approximately $91,000 (at December 31, 2011 exchange rates) and Edgewater of $65,000. In addition, LFB has access to the Eurosystem Covered Bond Purchase Program of the Banque de France.

Subordinated Debt—Subordinated debt at December 31, 2010 represented a promissory note amounting to $150,000. The note had a maturity date of September 30, 2016 and had a fixed interest rate of 3.25% per annum. Until June 30, 2011, the note had a conversion feature which permitted the holder to convert the note into a maximum of 2,631,570 shares of Class A common stock at an effective conversion price of $57 per share. No conversions had occurred. On July 22, 2011, the Company repurchased the note, at a cost, excluding accrued interest, of $131,829. Such repurchase resulted in a pre-tax gain of $18,171, which was recognized by the Company in the third quarter of 2011 and included in “revenue-other” on the accompanying consolidated statement of operations.

Debt maturities relating to senior borrowings outstanding at December 31, 2011 for each of the five years in the period ending December 31, 2016, and thereafter, are set forth in the table below.

Year Ending December 31,
2012-2014	$	–

The Company’s debt at December 31, 2011 and 2010 is recorded at historical amounts. At December 31, 2011 and 2010, the fair value of the Company’s senior and subordinated debt outstanding was approximately $1,138,000 and $1,271,000, respectively, and exceeded the aggregate carrying value by approximately $61,000 and $44,000, respectively. The fair value of the Company’s senior and subordinated debt was estimated using a discounted cash flow analysis based on the Company’s current borrowing rates for similar types of borrowing arrangements or based on market quotations, where available.

14. COMMITMENTS AND CONTINGENCIES

With respect to abandoned leased facilities in the U.K., at December 31, 2011 and 2010, the Company has recognized liabilities of $10,632 and $7,194, respectively, which are included in “other liabilities” on the consolidated statements of financial condition. Payments toward the liabilities continue through the remaining term of the leases. Such liabilities are based on the discounted future commitment, net of expected sublease income. During the year ended December 31, 2011, the Company recorded a charge of $5,539 related to such abandoned lease facilities, which is included within “occupancy and equipment” on the consolidated statement of operations.

Guarantees—In the normal course of business, LFB provides indemnifications to third parties to protect them in the event of non-performance by its clients. At December 31, 2011, LFB had $3,907 of such indemnifications and held $2,655 of collateral/counter-guarantees to secure these commitments. The Company believes the likelihood of loss with respect to these indemnities is remote. Accordingly, no liability is recorded in the consolidated statement of financial condition.

Other Commitments—In the normal course of business, LFB enters into commitments to extend credit, predominately at variable interest rates. Such commitments at December 31, 2011 aggregated $15,647. These commitments have varying expiration dates and are fully collateralized and generally contain requirements for the counterparty to maintain a minimum collateral level. These commitments may not represent future cash requirements as they may expire without being drawn upon.

See Notes 6, 8, 9 and 17 of Notes to Consolidated Financial Statements for information regarding commitments relating to investment capital funding commitments, the LAM Merger, business acquisitions and obligations to fund our pension plans, respectively.

The Company has various other contractual commitments arising in the ordinary course of business. In addition, from time to time, LFB enters into underwriting commitments in which it participates as a joint underwriter. The settlement of such transactions are not expected to have a material adverse effect on the Company’s consolidated financial position or results of operations. At December 31, 2011, LFB had no such underwriting commitments.

In the opinion of management, the fulfillment of the commitments described herein will not have a material adverse effect on the Company’s consolidated financial position or results of operations.

Legal—The Company is involved from time to time in judicial, regulatory and arbitration proceedings and inquiries concerning matters arising in connection with the conduct of our businesses, including proceedings initiated by former employees alleging wrongful termination. The Company reviews such matters on a case-by-case basis and establishes any required accrual if a loss is probable and the amount of such loss can be reasonably estimated. The Company does experience significant variation in its revenue and earnings on a quarterly basis. Accordingly, the results of any pending matter or matters could be significant when compared to the Company’s earnings in any particular fiscal quarter. The Company believes, however, based on currently available information, that the results of any pending matters, in the aggregate, will not have a material effect on its business or financial condition.

The remaining 7,921 and 17,159 shares of Series A preferred stock outstanding at December 31, 2011 and 2010, respectively, may become convertible into shares of Class A common stock upon completion or satisfaction of specified obligations in the applicable acquisition agreement (see Note 9 of Notes to Consolidated Financial Statements). The Series A preferred stock conversion rate into shares of Class A common stock varies, with the ultimate conversion rate dependent on certain variables, including the value of the Class A common stock, as defined, and the currency exchange rate on the date of conversion.

16. INCENTIVE PLANS

Share-Based Incentive Plan Awards

A description of Lazard Ltd’s 2005 Plan and 2008 Plan and activity with respect thereto during the years ended December 31, 2011, 2010 and 2009, is presented below.

Shares Available Under the 2005 Plan and 2008 Plan

The 2005 Plan authorizes the issuance of up to 25,000,000 shares of Class A common stock pursuant to the grant or exercise of stock options, stock appreciation rights, restricted stock, stock units and other equity-based awards. Each stock unit granted under the 2005 Plan represents a contingent right to receive one share of Class A common stock, at no cost to the recipient. The fair value of such stock unit awards is determined based on the closing market price of Class A common stock at the date of grant.

In addition to the shares available under the 2005 Plan, additional shares of Class A common stock are available under the 2008 Plan. The maximum number of shares available under the 2008 Plan is based on a formula that limits the aggregate number of shares that may, at any time, be subject to awards that are considered “outstanding” under the 2008 Plan to 30% of the then-outstanding shares of Class A common stock (treating, for this purpose, the then-outstanding exchangeable interests of LAZ-MD Holdings on a “fully-exchanged” basis as described in the 2008 Plan).

Restricted and Deferred Stock Units

RSUs generally require future service as a condition for the delivery of the underlying shares of Class A common stock (unless the recipient is then eligible for retirement under the Company’s retirement policy) and convert into Class A common stock on a one-for-one basis after the stipulated vesting periods. The grant date fair value of the RSUs, net of an estimated forfeiture rate, is amortized over the vesting periods or requisite service periods, and, for purposes of calculating diluted net income per share, are included in the diluted weighted average shares of Class A common stock outstanding using the treasury stock method. Expense relating to RSUs was as follows within the Company’s consolidated statements of operations:

	Year Ended December 31,
	2011		2010		2009
Compensation and benefits (*)	$	264,110	$	256,214	$	333,823
Restructuring		–		46,880		24,239
Total	$	264,110	$	303,094	$	358,062

(*) Includes, during the year ended December 31, 2010, $24,860 relating to the amendment of the Company’s retirement policy (described below) and, during the year ended December 31, 2009, $86,514 of accelerated amortization expense relating to awards held by Lazard’s former Chairman and Chief Executive Officer as a result of his death.

RSUs issued subsequent to December 31, 2005 generally include a dividend participation right that provides that during vesting periods each RSU is attributed additional RSUs (or fractions thereof) equivalent to any ordinary quarterly dividends paid on Class A common stock during such period. During the years ended December 31, 2011, 2010 and 2009, issuances of RSUs pertaining to such dividend participation rights and respective charges to “retained earnings”, net of estimated forfeitures, (with corresponding credits to “additional paid-in-capital”) consisted of the following:

	Year Ended December 31,
	2011		2010		2009
Number of RSUs issued		389,846		318,025		331,642
Charges to retained earnings, net of estimated forfeitures	$	11,120	$	9,522	$	4,042

In January 2010, the Company amended its retirement policy with respect to RSU awards. Such amendment served to modify the retirement eligibility vesting requirements of existing and future RSU awards, and, as noted above, Lazard accelerated the recognition of compensation expense for the affected RSU awards. Accordingly, the Company recorded a non-cash charge to “compensation and benefits” expense of $24,860 in the first quarter of 2010 relating to prior years’ awards.

Non-executive members of the Board of Directors receive approximately 55% of their annual compensation for service on the Board of Directors and its committees in the form of DSUs, which resulted in 26,859, 31,588 and 36,627 DSUs granted during the years ended December 31, 2011, 2010 and 2009, respectively. Their remaining compensation is payable in cash, which they may elect to receive in the form of additional DSUs under the Directors’ Fee Deferral Unit Plan described below. DSUs are convertible into Class A common stock at the time of cessation of service to the Board. The DSUs include a cash dividend participation right equivalent to any ordinary quarterly dividends paid on Class A common stock, and resulted in nominal cash payments for the years ended December 31, 2011, 2010 and 2009.

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

On May 9, 2006, the Board of Directors adopted the Directors’ Fee Deferral Unit Plan, which allows the Company’s Non-Executive Directors to elect to receive additional DSUs pursuant to the 2005 Plan in lieu of some or all of their cash fees. The number of DSUs that shall be granted to a Non-Executive Director pursuant to this election will equal the value of cash fees that the applicable Non-Executive Director has elected to forego pursuant to such election, divided by the market value of a share of Class A common stock on the date on which the foregone cash fees would otherwise have been paid. During the years ended December 31, 2011, 2010 and 2009, 8,184, 7,438 and 8,899 DSUs, respectively, had been granted pursuant to such Plan.

DSU awards are expensed at their fair value on their date of grant, which, inclusive of amounts related to the Directors’ Fee Deferral Unit Plan, totaled $1,265, $1,230 and $1,316 during the years ended December 31, 2011, 2010 and 2009, respectively.

The following is a summary of activity relating to RSUs and DSUs during the three-year period ended December 31, 2011:

During the years ended December 31, 2011, 2010 and 2009, 8,054,387 RSUs, 8,248,654 RSUs and 5,948,920 RSUs (including the acceleration of 4,406,440 RSUs held by Lazard’s former Chairman and Chief Executive Officer as a result of his death) vested, respectively, and, during the year ended December 31, 2010, 40,895 RSUs were exchanged for 40,895 shares of restricted Class A common stock. In connection with the vested RSUs, the Company satisfied certain employees’ tax obligations in lieu of issuing 2,353,561, 1,674,261 and 446,172 shares of Class A common stock in the years ended December 31, 2011, 2010 and 2009, respectively. Accordingly, 5,700,826, 6,574,393 and 5,502,748 shares of Class A common stock held by Lazard Group were delivered during the years ended December 31, 2011, 2010 and 2009, respectively.

As of December 31, 2011, unrecognized RSU compensation expense, adjusted for estimated forfeitures, was approximately $259,000, with such unrecognized compensation expense expected to be recognized over a weighted average period of approximately 1.3 years subsequent to December 31, 2011. The ultimate amount of such expense is dependent upon the actual number of RSUs that vest. The Company periodically assesses the forfeiture rates used for such estimates. A change in estimated forfeiture rates would cause the aggregate amount of compensation expense recognized in future periods to differ from the estimated unrecognized compensation expense described herein.

Restricted Stock

The following is a summary of activity related to shares of restricted Class A common stock associated with compensation arrangements during the two-year period ended December 31, 2011:

	Restricted Shares			Weighted Average Grant Date Fair Value
Balance, January 1, 2010		–			–
Granted/Exchanged (a)		95,332		$	37.63
Vested		–			–
Balance, December 31, 2010		95,332		$	37.63
Granted		327,238		$	43.70
Vested		(327,238	)	$	43.70
Balance, December 31, 2011		95,332		$	37.63

(a) Includes 40,895 shares of restricted Class A common stock issued in exchange for 40,895 RSUs previously granted during the year at a grant date fair value of $36.10 per share. The vesting terms of such restricted Class A common stock issued are the same as those of the original award exchanged. There was no incremental compensation cost incurred as a result of the exchange.

The Company satisfied certain employees’ tax obligations in lieu of delivering 68,866 shares of Class A common stock in connection with shares of restricted Class A common stock that vested during the year ended December 31, 2011. Accordingly, 258,372 shares of Class A common stock held by the Company were delivered during the year ended December 31, 2011.

Expense relating to restricted stock awards is charged to “compensation and benefits” expense within the Company’s consolidated statements of operations, and amounted to $9,767 and $979 for the years ended December 31, 2011 and 2010, respectively. The awards include a cash dividend participation right equivalent to any ordinary quarterly dividends paid on Class A common stock during the period, which will vest concurrently with the underlying restricted stock award. At December 31, 2011, unrecognized restricted stock expense was approximately $957, with such expense to be recognized over a weighted average period of approximately 0.7 years subsequent to December 31, 2011.

For purposes of calculating diluted net income per share, such awards are included in the diluted weighted average shares of Class A common stock outstanding using the “treasury stock” method.

Lazard Fund Interests

As previously described, in February 2011 the Company granted to eligible employees Lazard Fund Interests. In connection with the Lazard Fund Interests and other similar deferred compensation arrangements, the Company recorded a prepaid compensation asset and a corresponding compensation liability on the grant date based upon the fair value of the award. The prepaid asset is amortized on a straight-line basis over the applicable vesting periods or requisite service periods, and is charged to “compensation and benefits” expense within the Company’s consolidated statement of operations, and amounted to $14,551 for the year ended December 31, 2011. Lazard Fund Interests and similar deferred compensation arrangements that do not require future service are expensed immediately. The related compensation liability is accounted for at fair value as a derivative liability, and is adjusted for changes in fair value primarily related to the changes in the fair value of the underlying investments. Such changes in the fair value of the derivative liability are recorded to “compensation and benefits” expense within the Company’s consolidated statements of operations, the impact of which equally offsets the changes in fair value of the underlying investments owned and is reported in “revenue-other” in the consolidated statement of operations (see Note 7 of Notes to Consolidated Financial Statements).

The Lazard Fund Interests granted as of December 31, 2011 generally provide for one-third vesting on March 1, 2013 and two-thirds vesting on March 3, 2014. As of December 31, 2011, unrecognized compensation expense for Lazard Fund Interests and other similar deferred compensation arrangements, adjusted for estimated forfeitures, was approximately $18,000. Such compensation expense will generally be recognized over a weighted average period of approximately 1.8 years subsequent to December 31, 2011.

Incentive Awards Granted In February 2009

A portion of the incentive awards granted in February 2009 included a deferred cash component, which was originally scheduled to vest over a maximum period of four years. During the fourth quarter of 2009, in connection with a review of the Company’s compensation policy, the Company accelerated the vesting of the then unamortized portion of such previously awarded deferred cash incentive awards which resulted in a pre-tax charge to “compensation and benefits” expense of $60,512.

Incentive Awards Granted In February 2012

In February 2012, the Company granted approximately $281,000 of deferred incentive awards to eligible employees. These grants included approximately 6.1 million RSUs or shares of restricted Class A common stock, that in accordance with U.S. GAAP, were measured at the grant date fair value of $27.57 per RSU or share of restricted Class A common stock, or an aggregate of approximately $168,000. In addition, eligible employees will have the choice of receiving a portion of their deferred incentive awards in a combination of (i) Lazard Fund Interests, and (ii) additional RSUs or shares of restricted Class A common stock. The aggregate fair value on the date of grant of these awards is approximately $102,000. The remaining deferred incentive awards include deferred cash awards and a portion of fund managers’ year-end incentive compensation that is reinvested in certain asset management funds. The aggregate fair value on the date of grant of these awards is approximately $11,000.

The RSUs, restricted stock and Lazard Fund Interests granted each provide for one-third vesting on March 3, 2014 and the remaining two-thirds vesting on March 2, 2015. Compensation expense with respect to such incentive awards will generally be recognized over the vesting period, with such compensation expense to be recognized over a weighted average period of approximately 2.7 years.

17. EMPLOYEE BENEFIT PLANS

The Company provides retirement and other post-retirement benefits to certain of its employees through defined contribution and defined benefit pension plans and other post-retirement plans. These plans generally provide benefits to participants based on average levels of compensation. Expenses related to the Company’s employee benefit plans are included in “compensation and benefits” expense on the consolidated statements of operations.

The Company also offers a partially funded contributory post-retirement medical plan covering qualifying U.S. employees (the “Medical Plan”). The Medical Plan pays a stated percentage of most necessary medical expenses incurred by retirees, after subtracting payments by Medicare or other providers and after stated deductibles have been met. Participants become eligible for benefits if they retire from the Company after meeting certain age and service requirements. Effective January 1, 2005, post-retirement health care benefits are no longer offered to those managing directors and employees hired on or after January 1, 2005 and for those managing directors and employees hired before January 1, 2005 who did not attain the age of 40 before December 31, 2005. In addition, effective January 1, 2006, the cost sharing policy changed for those who qualify for the benefit. The plan was amended effective January 1, 2008, such that previously ineligible managing directors and employees who meet the Medical Plan’s age and service requirements have the ability, upon retirement, to elect to purchase medical coverage through the Medical Plan at no cost to the Company. The Company will continue to contribute towards the cost of retiree medical premiums for those employees hired before January 1, 2005 who were age 55 or older on or before December 31, 2005.

Employer Contributions to Pension Plans—The Company’s funding policy for its U.S. and non-U.S. pension plans is to fund when required or when applicable upon an agreement with the plans’ Trustees. Management also evaluates from time to time whether to make voluntary contributions to the plans. The Company did not make any contributions to the U.S. pension plans during the year ended December 31, 2011, however it expects to make a contribution of approximately $700 to the U.S. pension plans in the year ending December 31, 2012.

In accordance with agreements reached with the Trustees of certain U.K. pension plans in 2005, the Company was obligated to make further contributions to such pension plans based upon the cumulative performance of the plans’ assets against specific benchmarks as measured on June 1, 2009 and subsequently remeasured on June 1, 2010. As of December 31, 2009, the obligation related to the cumulative underperformance of the plans’ assets (the “underperformance obligation”) was payable in equal monthly installments through May 2013. During the year ended December 31, 2010, the Company contributed approximately $8,600 to settle the plans’ underperformance obligation in full.

Further on June 30, 2009 the Company and the Trustees concluded the December 31, 2007 triennial valuation of the U.K. pension plans discussed above, pursuant to which the Company agreed to annual future contributions to the plan through 2018. The agreement also required the Company to secure its obligations’ to the pension plans by placing in escrow 12.5 million British pounds (with the Company depositing such amount in escrow in July 2009), with a final redemption date of December 31, 2018. The aggregate escrow balance at December 31, 2010 had been recorded in “cash deposited with clearing organizations and other segregated cash” and “investments” on the accompanying consolidated statement of financial condition. The terms of this agreement were subject to adjustment based on the results of the December 31, 2010 triennial valuation and subsequent triennial valuations.

During 2011, the Company and the Trustees of the U.K. pension plans referred to above commenced negotiations regarding the terms of the December 31, 2010 triennial valuations of the plans and potential future contributions to the plans. We currently anticipate that the valuations will be concluded by March 31, 2012, with a tentative agreement having been reached in principle that would supersede the June 2009 agreement described above and that provides pension funding terms whereby the Company: (i) made a contribution in December 2011 to the plans of 2.3 million British pounds ($3,687 at December 31, 2011 exchange rates) from the escrow account, (ii) will make contributions of 1 million British pounds during each year from 2012 through 2020 inclusive and (iii) will amend and extend the existing escrow arrangement into an account security arrangement covering 10 million British pounds from the existing escrow and additional contributions of 1 million British pounds into such account security arrangement during each year from 2014 through 2020, inclusive, with an agreement that assets from the account security arrangements will be released into the plans if and to the extent that the value of the plans’ assets falls short of the funding target for June 1, 2020 that has been agreed upon with the Trustees. The terms of the tentative agreement are subject to adjustment based on the results of subsequent triennial valuations. Additionally, the Company is discussing with the Trustees the extent to which the Company would contribute to the plans to cover their administrative expenses. The aggregate escrow balance at December 31, 2011 has been recorded in “cash deposited with clearing organizations and other segregated cash” on the accompanying consolidated statement of financial condition. Income on the escrow balance accretes to the Company and is recorded in interest income.

Additionally, during the year ended December 31, 2011, contributions made to other non-U.S. pension plans amounted to $4,867. The Company expects to contribute a similar amount to these other non-U.S. pension plans in the year ending December 31, 2012.

The assumptions used to develop actuarial present value of the projected benefit obligation and net periodic pension cost as of or for the years ended December 31, 2011, 2010 and 2009 are set forth below:

	Pension Plans December 31,									Post-Retirement Medical Plan December 31,
	2011			2010			2009			2011			2010		2009
Weighted average assumptions used to determine benefit obligations:
Discount rate		4.8	%		5.4	%		5.7	%		4.1	%		5.0%		5.6%
Weighted average assumptions used to determine net periodic benefit cost:
Discount rate		4.7	%		5.0	%		5.5	%		5.0	%		5.6%		5.8%
Expected long-term rate of return on plan assets		5.4	%		5.9	%		6.2	%		–			–		–
Healthcare cost trend rates used to determine net periodic benefit cost:
Initial											8.0	%		8.5%		9.0%
Ultimate											6.0	%		6.0%		6.0%
Year ultimate trend rate achieved											2015			2015		2015

Generally, the Company determined the discount rates for its defined benefit plans by utilizing indices for long-term, high-quality bonds and ensuring that the discount rate does not exceed the yield reported for those indices after adjustment for the duration of the plans’ liabilities.

In selecting the expected long-term rate of return on plan assets, the Company considered the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of the plan, giving consideration to expected returns on different asset classes held by the plans in light of prevailing economic conditions as well as historic returns. This basis is consistent for all years presented.

The assumed cost of healthcare has an effect on the amounts reported for the Company’s post-retirement plans. A 1% change in the assumed healthcare cost trend rate would increase (decrease) our cost and obligation as follows:

	1% Increase				1% Decrease
	2011		2010		2011			2010
Cost	$	66	$	39	$	(49	)	$	(34	)
Obligation	$	929	$	1,231	$	(649	)	$	(891	)

Expected Benefit Payments—The following table summarizes the expected benefit payments for the Company’s plans for each of the next five fiscal years and in the aggregate for the five fiscal years thereafter:

	Pension Plans		Post-Retirement Medical  Plan

Activity in the fair value of the plans’ Level 3 debt mutual funds for the year ended December 31, 2011 consisted of purchases and net unrealized/realized gains of $1,837 and $3, respectively, partially offset by unfavorable foreign currency translation adjustments of $63.

At December 31, 2011 and 2010, the Company’s U.S. pension plans had 46% and 52%, respectively, of the plans’ assets invested in exchange-traded mutual funds that invest in equity securities and 54% and 48%, respectively, invested in an exchange-traded mutual fund that invests in debt securities, both of which are categorized as Level 1. The Company’s non-U.S. pension plans at December 31, 2011 and 2010 had 36% and 43%, respectively, of the plans’ assets invested in certain debt mutual funds which are categorized as Level 2. The Company’s other non-U.S. pension plans’ investment holdings did not individually constitute more than 10% of non-U.S. pension plan assets at December 31, 2011 and 2010.

Investment Policies and Strategies—The primary investment goal is to ensure that the plans remain well funded, taking account of the likely future risks to investment returns and contributions. As a result, a portfolio of assets is maintained with appropriate liquidity and diversification that can be expected to generate long-term future returns that minimize the long-term costs of the pension plans without exposing the trust to an unacceptable risk of under-funding. The Company’s likely future ability to pay such contributions as are required to maintain the funded status of the plans over a reasonable time period is considered when determining the level of risk that is appropriate. The fair values of plan investments classified as Level 1 assets are based on market quotes. The fair values of plan assets classified as Level 2 assets are primarily based on information provided by fund managers.

Defined Contribution Plans—Pursuant to certain matching contributions, the Company contributes to employer sponsored defined contribution plans. Such contributions amounted to $10,944, $9,684 and $8,409 for the years ended December 31, 2011, 2010 and 2009, respectively, which are included in “compensation and benefits” expense on the consolidated statements of operations.

18. RESTRUCTURING PLANS

In each of the first quarters of 2010 and 2009, the Company announced a restructuring plan which included certain staff reductions and realignments of personnel (the “2010 Restructuring Plan” and the “2009 Restructuring Plan”, respectively, and collectively the “2010 and 2009 Restructuring Plans”). In connection with the 2010 Restructuring Plan, the Company recorded a charge in the first quarter of 2010 of $87,108, inclusive of $46,880 relating to the acceleration of RSUs (in aggregate, the “2010 Restructuring Charge”), and, in connection with the 2009 Restructuring Plan, the Company recorded a charge in the first quarter of 2009 of $62,550, inclusive of $24,239 relating to the acceleration of RSUs (in aggregate, the “2009 Restructuring Charge”, and, together with the 2010 Restructuring Charge, the “2010 and 2009 Restructuring Charges”).

The 2010 and 2009 Restructuring Charges primarily consisted of compensation-related expenses, including the acceleration of unrecognized expenses pertaining to RSUs previously granted to individuals who were terminated pursuant to the restructuring, severance and benefit payments and other costs. As of December 31, 2011 and 2010, the remaining liability associated with the 2010 Restructuring Plan was $9,456 and $21,381, respectively, and, as of December 31, 2011 and 2010, the remaining liability associated with the 2009 Restructuring Plan was $2,791 and $5,427, respectively. During the years ended December 31, 2011 and 2010, the Company made cash payments of $10,625 and $18,847, respectively, for the 2010 Restructuring Plan and $1,436 and $6,073, respectively, for the 2009 Restructuring Plan. Further during the year ended December 31, 2011, we reduced our provisions by $1,300 and $1,200 for the 2010 and 2009 Restructuring Plans, respectively. Liabilities relating to the 2010 and 2009 Restructuring Plans are reported within “accrued compensation and benefits” and “other liabilities” on the accompanying consolidated statements of financial condition.

19. INCOME TAXES

As a result of its indirect investment in Lazard Group, Lazard Ltd, through certain of its subsidiaries, is subject to U.S. federal income taxes on its portion of Lazard Group’s operating income. Although a portion of Lazard Group’s income is subject to U.S. federal income taxes, Lazard Group primarily operates in the U.S. as a limited liability company that is treated as a partnership for U.S. federal income tax purposes. As a result, Lazard Group’s income from its U.S. operations is generally not subject to U.S. federal income taxes because such income is attributable to its partners. In addition, Lazard Group is subject to UBT which is attributable to Lazard Group’s operations apportioned to New York City. UBT is incremental to the U.S. federal statutory tax rate. Outside the U.S., Lazard Group operates principally through subsidiary corporations that are subject to local income taxes.

Deferred income taxes are provided for the effects of temporary differences between the tax basis of an asset or liability and its reported amount in the consolidated statements of financial condition. These temporary differences result in taxable or deductible amounts in future years. Details of the Company’s deferred tax assets and liabilities, which are included in “other assets” and “other liabilities”, respectively, on the consolidated statements of financial condition, are as follows:

	December 31,
	2011			2010
Deferred Tax Assets:
Basis adjustments (primarily as a result of the separation and recapitalization transactions that occurred during 2005 and from secondary offerings)	$	846,252		$	877,143
Compensation and benefits		196,133			207,080
Net operating loss and tax credit carryforwards		209,781			156,798
Depreciation and amortization		1,519			14,785
Other		25,410			39,316
Gross deferred tax assets		1,279,095			1,295,122
Valuation allowance		(1,145,257	)		(1,165,274	)
Total deferred tax assets (net of valuation allowance)	$	133,838		$	129,848
Deferred Tax Liabilities:
Depreciation and amortization	$	16,240		$	16,469
Compensation and benefits		10,729			20,563
Goodwill		15,031			9,839
Other		41,581			35,201
Total deferred tax liabilities	$	83,581		$	82,072

The basis adjustments recorded as of December 31, 2011 and 2010 are the result of:

• purchases and redemptions of historical and working member interests consummated in connection with the separation and recapitalization of the Company, which resulted in deferred tax assets of $176,871 and $196,049 at December 31, 2011 and 2010, respectively,

• tax basis step-ups resulting from the exchange of LAZ-MD exchangeable interests and from secondary offerings, and associated with the LAM Merger which in the aggregate resulted in deferred tax assets of $638,069 and $640,720 at December 31, 2011 and 2010, respectively,

• tax basis step-up for U.S. income tax purposes on certain U.K. assets, which resulted in deferred tax assets of $24,338 and $32,455 at December 31, 2011 and 2010, respectively, and

• tax basis step-up for payments made under the tax receivable agreement of $6,974 and $7,919 at December 31, 2011 and 2010, respectively.

Although we have been profitable on a consolidated basis in the last two years, certain of our tax-paying entities have individually experienced pre-tax losses on a cumulative three-year basis primarily due to permanent differences between net income and taxable income at such entities. Considering these losses and the other factors listed below, we have recorded valuation allowances on our deferred tax assets of $1,145,257 and $1,165,274 as of December 31, 2011 and December 31, 2010, respectively. If these entities achieve sustainable levels of profitability in the future, we believe there is a reasonable possibility that the valuation allowance recorded against our deferred tax assets at such entities could be reduced significantly. The valuation allowance at December 31, 2011 reflects a net decrease of $20,017 from the balance of $1,165,274 at December 31, 2010.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company had net operating loss and tax credit carryforwards for which related deferred tax assets were recorded at December 31, 2011 primarily relating to:

(i) indefinite-lived carryforwards (subject to various limitations,) of approximately $50,800, primarily in the U.K. and Italy, and

(ii) certain carryforwards of approximately $137,100 in the U.S., which begin expiring in 2029.

As a result of certain realization requirements regarding share-based incentive plan awards, certain deferred tax assets pertaining to tax deductions related to equity compensation in excess of compensation recognized for financial reporting that would otherwise have been recognized at December 31, 2011 and 2010 of $19,900 and $9,065, respectively, are not included in the table above. The impact of such excess tax deductions will be recorded in stockholders’ equity if and when such deferred tax assets are ultimately realized.

With few exceptions, the Company is no longer subject to income tax examination by foreign tax authorities and by U.S. federal, state and local tax authorities for years prior to 2007. While we are under examination in various tax jurisdictions with respect to certain open years, the Company believes that the result of any final determination related to these examinations is not expected to have a material impact on its financial statements. Developments with respect to such examinations are monitored on an ongoing basis and adjustments to tax liabilities are made as appropriate.

A reconciliation of the beginning to the ending amount of gross unrecognized tax benefits (excluding interest and penalties) for the years ended December 31, 2011, 2010 and 2009 is as follows:

	Year Ended December 31,
	2011			2010			2009
Balance, January 1 (excluding interest and penalties of $7,099, $7,247 and $5,467, respectively)	$	58,605		$	60,558		$	46,725

Prior years		1,081			2,184			5,271

Additional information with respect to unrecognized tax benefits is as follows:

	Year Ended December 31,
	2011		2010			2009
Unrecognized tax benefits at the end of the year that, if recognized, would favorably affect the effective tax rate (includes interest and penalties of $8,454, $7,099 and $7,247, respectively)	$	44,545	$	39,112		$	41,405
Offset to deferred tax assets for unrecognized tax benefits	$	26,109	$	26,592		$	26,400

The Company anticipates that it is reasonably possible that the total amount of unrecognized tax benefits recorded at December 31, 2011 will decrease within 12 months by an amount up to approximately $10,000 as a result of the lapse of the statute of limitations in various tax jurisdictions.

Tax Receivable Agreement

The redemption of historical partner interests in connection with the Company’s separation and recapitalization that occurred in May 2005 and the subsequent exchanges through December 31, 2011 of LAZ-MD Holdings exchangeable interests for shares of Class A common stock have resulted, and future exchanges of LAZ-MD Holdings exchangeable interests for shares of Class A common stock may result, in increases in the tax basis of the tangible and/or intangible assets of Lazard Group. Included in our deferred tax assets as of December 31, 2011 are approximately $709,000 related to certain basis step-up assets and approximately $137,000 of net operating losses generated by the amortization of such step-up assets. The tax receivable agreement dated as of May 10, 2005 with LFCM Holdings requires the Company to pay LFCM Holdings 85% of the cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes as a result of the above-mentioned increases in tax basis. During the years ended December 31, 2011, 2010 and 2009, the Company recorded a “provision (benefit) pursuant to tax receivable agreement” on the consolidated statements of operations of $429, $2,361 and $(1,258), respectively, with the liability related thereto at December 31, 2011 and 2010 of $2,790 and $2,361, respectively, included within “related party payables” on the consolidated statements of financial condition (see Note 21 of Notes to Consolidated Financial Statements). During the year ended December 31, 2009, the Company recorded a benefit related to the tax receivable agreement as a result of certain adjustments to previously recorded estimated provisions.

LFCM Holdings

LFCM Holdings owns and operates the capital markets business and fund management activities, as well as other specified non-operating assets and liabilities, that were transferred to it by Lazard Group (referred to as the “separated businesses”) in May 2005 and is owned by various current and former working members, including certain of Lazard’s current and former managing directors (which also include certain of the Company’s executive officers) who were or are also members of LAZ-MD Holdings. In addition to the master separation agreement, dated as of May 10, 2005, by and among Lazard Ltd, Lazard Group, LAZ-MD Holdings and LFCM Holdings (the “master separation agreement”), which effected the separation and recapitalization that occurred in May 2005, LFCM Holdings entered into an insurance matters agreement and a license agreement that addressed various business matters associated with the separation, as well as several other agreements discussed below.

Under the employee benefits agreement, dated as of May 10, 2005, by and among Lazard Ltd, Lazard Group, LAZ-MD Holdings and LFCM Holdings, LFCM Holdings generally assumed, as of the completion of the separation and recapitalization transactions, all outstanding and future liabilities in respect of the current and former employees of the separated businesses. The Company retained all accrued liabilities under, and assets of, the pension plans in the U.S. and the U.K. as well as the 401(k) plan accounts of the inactive employees of LFCM Holdings and its subsidiaries.

Pursuant to the administrative services agreement, dated as of May 10, 2005, by and among LAZ-MD Holdings, LFCM Holdings and Lazard Group (the “administrative services agreement”), Lazard Group provides selected administrative and support services to LAZ-MD Holdings and LFCM Holdings, such as cash management and debt service administration, accounting and financing activities, tax, payroll, human resources administration, financial transaction support, information technology, public communications, data processing, procurement, real estate management and other general administrative functions. Lazard Group charges for these services based on Lazard Group’s cost allocation methodology.

The services provided pursuant to the administrative services agreement by Lazard Group to LFCM Holdings, and by LFCM Holdings to Lazard Group, are subject to automatic annual renewal, unless either party gives 180 days’ notice of termination. LFCM Holdings and Lazard Group have a right to terminate the services earlier if there is a change of control of either party or the business alliance provided in the business alliance agreement entered into on May 10, 2005, by and among LAZ-MD Holdings, LFCM Holdings and Lazard Group

(the “business alliance agreement”) (described below) expires or is terminated. The party receiving a service may also terminate a service earlier upon 180 days’ notice as long as the receiving party pays the service provider an additional three months of service fee for the terminated service. In addition, in connection with the various agreements entered into regarding the CP II MgmtCo Spin-Off described below, Lazard Group agreed to provide certain specified services to LFCM Holdings (which, in turn, LFCM Holdings may provide to its subsidiary, CP II MgmtCo (“CP II MgmtCo”)).

The business alliance agreement provides, among other matters, that Lazard Group will refer to LFCM Holdings selected opportunities for underwriting and distribution of securities. In addition, Lazard Group will provide assistance in the execution of any such referred business. In exchange for the referral obligation and assistance, Lazard Group will receive a referral fee from LFCM Holdings equal to approximately one-half of the revenue obtained by LFCM Holdings in respect of any underwriting or distribution opportunity. In addition, LFCM Holdings will refer opportunities in the Financial Advisory and Asset Management businesses to Lazard Group. In exchange for this referral, LFCM Holdings will be entitled to a customary finders’ fee from Lazard Group. The business alliance agreement further provides that, during the term of the business alliance, LFNY and Lazard Asset Management Securities LLC, an indirect wholly-owned subsidiary of LFNY, will introduce execution and settlement transactions to broker-dealer entities affiliated with LFCM Holdings. The business alliance agreement is subject to periodic automatic renewal, unless Lazard Group or LFCM Holdings elects to terminate the agreement in connection with any such renewal or elects to terminate on account of a change of control of either party.

For the years ended December 31, 2011, 2010 and 2009, amounts recorded by Lazard Group relating to the administrative services agreement amounted to $10,277, $12,110 and $9,717, respectively, and net referral fees for underwriting, private placement, M&A and restructuring transactions under the business alliance agreement amounted to $18,862, $11,506 and $12,301, respectively. Amounts relating to the administrative services agreement are reported as reductions to operating expenses. Net referral fees for underwriting transactions under the business alliance agreement are reported in “revenue-other”. Net referral fees for private placement, M&A and restructuring transactions under the business alliance agreement are reported in advisory fee revenue.

Receivables from LFCM Holdings and its subsidiaries as of December 31, 2011 and 2010 primarily include $10,722 and $12,775, respectively, related to administrative and support services and reimbursement of expenses incurred on behalf of LFCM Holdings, and $2,928 and $11,413, respectively, related to referral fees for underwriting and private placement transactions. Payables to LFCM Holdings and its subsidiaries at December 31, 2011 and 2010 relate primarily to obligations pursuant to the tax receivable agreement of $2,790 and $2,361, respectively (see Note 19 of Notes to Consolidated Financial Statements) and $2,060 and $458, respectively, principally relating to certain advances and referral fees for Financial Advisory transactions.

Other

For the years ended December 31, 2011 and 2010, amounts recorded by Lazard Group relating to referral fees for restructuring transactions and fee sharing with MBA Lazard Holdings S.A. Group (“MBA”), an Argentina-based group in which the Company has a 50% ownership interest, amounted to $1,866 and $128, respectively, and are reported in advisory fee revenue. There were no such amounts for the year ended December 31, 2009.

Other receivables at December 31, 2011 and 2010 and payables at December 31, 2011 primarily relate to referral fees for restructuring and M&A transactions with MBA and, in 2011, a related party loan.

LAZ-MD Holdings

Lazard Group provides selected administrative and support services to LAZ-MD Holdings through the administrative services agreement as discussed above, with such services generally to be provided until December 31, 2014 unless terminated earlier because of a change in control of either party. Lazard Group charges LAZ-MD Holdings for these services based on Lazard Group’s cost allocation methodology and, for the years ended December 31, 2011, 2010 and 2009, such charges amounted to $750 in each year.

Lazard Alternative Investments

The business alliance agreement, among other things, granted Lazard Group the option to acquire the North American and European fund management activities of Lazard Alternative Investments Holdings LLC (“LAI”), the subsidiary of LFCM Holdings that owns and operates LFCM Holdings’ alternative investment (including private equity) activities, for an aggregate purchase price of $8,000 and $2,000, respectively. On December 15, 2009, Lazard Group exercised its option to acquire the European fund management activities of LAI for a purchase price of $2,000. LAI’s fund management activities consist of the fund management and general partner entities, together with Lazard Group’s direct investments in related funds that were transferred to LFCM Holdings pursuant to or in anticipation of the May 10, 2005 separation (the “separation”) from the Company of its former Capital Markets and Other business segment.

The business alliance agreement provides Lazard Group with certain governance rights with respect to LAI and provides for support by LFCM Holdings of the business of LAI. With respect to historical investments and funds transferred to LFCM Holdings as part of the separation, profits realized prior to the exercise of the option are for the account of LFCM Holdings, whereas profits realized after the exercise of the option are for the account of Lazard Group. The master separation agreement and business alliance agreement provide for Lazard Group (i) to invest capital in future funds to be managed by LFCM Holdings’ subsidiaries and (ii) to receive incentive distributions from such funds, as well as profits related to such investments, if any, irrespective of whether it exercises its purchase option.

In February 2005, Lazard Group formed CP II, with institutional and Lazard Group capital commitments which required funding at any time through 2010, except for potential follow-on investments and/or CP II expenses. As of December 31, 2011, Lazard Group’s investment in CP II amounted to $31,533 which is recorded within “investments - other - private equity” on the consolidated statement of financial condition. Pursuant to the master separation agreement and business alliance agreement, CP II was managed by CP II MgmtCo, and Lazard Group is entitled to receive the carried interest distributions made by CP II (other than the carried interest distributions made to investment professionals who manage the fund).

In February 2009, pursuant to agreements entered into by the Company with a subsidiary of LAI (“LAI North America”), LFCM Holdings and the investment professionals who manage CP II, equity ownership of CP II MgmtCo was transferred from LAI North America to the investment professionals who manage CP II (the “CP II MgmtCo Spin-Off”). Concurrently with the CP II MgmtCo Spin-Off, CP II MgmtCo became a standalone entity. In addition, in connection with a February 2009 $4,000 cash payment from Lazard Group to LFCM Holdings relating to the CP II MgmtCo Spin-Off, the business alliance agreement was amended to remove any restriction on the Company engaging in private equity businesses in North America other than certain investments in real estate and technology and information services. Such amendment reduced the then purchase price relating to our option to acquire the fund management activities of LAI in North America from $6,500 to $2,500. As part of the CP II MgmtCo Spin-Off, we retained our entitlement to receive a slightly reduced portion of the carried interest distributions made by CP II.

(dollars in thousands, except for per share data, unless otherwise noted)

The remaining option to purchase the North American fund management activities is currently exercisable at any time prior to May 10, 2014, for a purchase price of $2,500 as described above. The reduced price for the North American option reflects (i) a reduction of $1,500 due to the payment of a like amount in February 2008 to LFCM Holdings in connection with the Sapphire IPO, whereby LFCM Holdings agreed not to assert certain claims that it may believe that it had under the business alliance agreement and (ii) the $4,000 payment described above.

During the fourth quarter of 2011, the Company determined that it was unlikely to exercise the North American option. Accordingly, during such period the Company wrote-off the $5,500 capitalized cost associated with the option which is included within “other” operating expenses on the consolidated statement of operations.

22. REGULATORY AUTHORITIES

LFNY is a U.S. registered broker-dealer and is subject to the net capital requirements of Rule 15c3-1 under the Exchange Act. Under the basic method permitted by this rule, the minimum required net capital, as defined, is a specified fixed percentage of total aggregate indebtedness recorded in LFNY’s Financial and Operational Combined Uniform Single (“FOCUS”) report filed with the Financial Industry Regulatory Authority (“FINRA”), or $100, whichever is greater. At December 31, 2011, LFNY’s regulatory net capital was $100,819, which exceeded the minimum requirement by $93,184.

Certain U.K. subsidiaries of the Company, including LCL, Lazard Fund Managers Limited and Lazard Asset Management Limited (the “U.K. Subsidiaries”) are authorized and regulated by the Financial Services Authority. At December 31, 2011, the aggregate regulatory net capital of the U.K. Subsidiaries was $149,345, which exceeded the minimum requirement by $137,437.

CFLF, under which asset management and commercial banking activities are carried out in France, is subject to regulation by the Autorité de Contrôle Prudentiel for its banking activities conducted through its subsidiary, LFB. In addition, the investment services activities of the Paris group, exercised through LFB and other subsidiaries of CFLF, primarily LFG (asset management), are subject to regulation and supervision by the Autorité des Marchés Financiers. At December 31, 2011, the consolidated regulatory net capital of CFLF was $175,781, which exceeded the minimum requirement set for regulatory capital levels by $81,099.

Certain other U.S. and non-U.S. subsidiaries are subject to various capital adequacy requirements promulgated by various regulatory and exchange authorities in the countries in which they operate. At December 31, 2011, for those subsidiaries with regulatory capital requirements, their aggregate net capital was $96,255, which exceeded the minimum required capital by $71,592.

At December 31, 2011, each of these subsidiaries individually was in compliance with its regulatory capital requirements.

Lazard Ltd had been subject to supervision by the SEC as a Supervised Investment Bank Holding Company (“SIBHC”). As a SIBHC, Lazard Ltd was subject to group-wide supervision, which required it to compute allowable capital and risk allowances on a consolidated basis. However, pursuant to Section 617 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the SEC’s SIBHC program was eliminated on July 21, 2011. Pursuant to relevant rules in the European Union, Lazard Ltd is required to be supervised by another regulatory body, either in the U.S. or the European Union. The Dodd-Frank Act allows certain securities holding companies seeking consolidated supervision, including Lazard Ltd, to elect to be supervised by the Board of Governors of the Federal Reserve. Lazard Ltd anticipates that the Board of

130

LAZARD LTD

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(dollars in thousands, except for per share data, unless otherwise noted)

Governors of the Federal Reserve will adopt regulations pursuant to Section 618 of the Dodd-Frank Act in the near future for companies that seek to come under its consolidated supervision. Once it analyzes the final scope of such regulations, Lazard Ltd will determine whether it will elect to register to come under the consolidated supervision of the Federal Reserve. Until such regulations are adopted, however, we cannot determine the full impact of such regulations on us. The Dodd-Frank Act and the rules and regulations that may be adopted thereunder (including regulations that have not yet been proposed) could have other effects on us. We continue to monitor the process as such rules are proposed and adopted.

23. SEGMENT INFORMATION

The Company’s reportable segments offer different products and services and are managed separately as different levels and types of expertise are required to effectively manage the segments’ transactions. Each segment is reviewed to determine the allocation of resources and to assess its performance. The Company’s principal operating activities are included in two business segments as described in Note 1 above - Financial Advisory and Asset Management. In addition, as described in Note 1 above, the Company records selected other activities in its Corporate segment.

The Company’s segment information for the years ended December 31, 2011, 2010 and 2009 is prepared using the following methodology:

• Revenue and expenses directly associated with each segment are included in determining operating income.

• Expenses not directly associated with specific segments are allocated based on the most relevant measures applicable, including headcount, square footage and other factors.

• Segment assets are based on those directly associated with each segment, and include an allocation of certain assets relating to various segments, based on the most relevant measures applicable, including headcount, square footage and other factors.

The Company allocates investment gains and losses, interest income and interest expense among the various segments based on the segment in which the underlying asset or liability is reported.

Each segment’s operating expenses include (i) compensation and benefits expenses incurred directly in support of the businesses and (ii) other operating expenses, which include directly incurred expenses for occupancy and equipment, marketing and business development, technology and information services, professional services, fund administration and outsourced services and indirect support costs (including compensation and other operating expenses related thereto) for administrative services. Such administrative services include, but are not limited to, accounting, tax, legal, facilities management and senior management activities.

There were no clients for the years ended December 31, 2011, 2010 and 2009 that individually constituted more than 10% of the net revenue of any of the Company’s business segments.

Geographic Information

Due to the highly integrated nature of international financial markets, the Company manages its business based on the profitability of the enterprise as a whole. Accordingly, management believes that profitability by geographic region is not necessarily meaningful. The Company’s revenue and identifiable assets are generally allocated based on the country or domicile of the legal entity providing the service.

The following table sets forth the net revenue from, and identifiable assets for, the Company and its consolidated subsidiaries by geographic region allocated on the basis described above.

The Parent Company Financial Statements as of December 31, 2011 and 2010, and for each of the three years in the period ended December 31, 2011, are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and the disclosures in the condensed financial statements. Management believes that the estimates utilized in the preparation of the condensed financial statements are reasonable. Actual results could differ materially from these estimates.

The Parent Company Financial Statements include investments in subsidiaries, accounted for under the equity method.

Exhibit 12.1

LAZARD LTD

COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES (a)

The following table sets forth the ratio of earnings to fixed charges for Lazard Ltd and its subsidiaries on a consolidated basis.

	Year Ended December 31,
	2011		2010			2009			2008			2007
	(dollars in thousands)
Operating income (loss)	$	235,499	$	243,650		$	(182,234	)	$	25,140		$	418,295
Add—Fixed charges		110,919		117,119			127,398			160,154			155,374
Operating income (loss) before fixed charges	$	346,418	$	360,769		$	(54,836	)	$	185,294		$	573,669
Fixed Charges:
Interest (b)	$	90,126	$	97,709		$	107,890		$	139,899		$	137,110
Other (c)		20,793		19,410			19,508			20,255			18,264
Total fixed charges	$	110,919	$	117,119		$	127,398		$	160,154		$	155,374
Ratio of earnings to fixed charges		3.12		3.08	(d)		–	(e)		1.16	(f)		3.69
Deficiency in the coverage of operating income (loss) before fixed charges to total fixed charges						$	182,234

Notes (dollars in thousands):

(a) For purposes of computing the ratio of earnings to fixed charges:

• earnings for the years presented represent income before income taxes and fixed charges, and

• fixed charges represent the interest expense and the portion of rental expense which represents an appropriate interest factor.

(b) The Company’s policy is to include interest expense on unrecognized tax benefits in income tax expense. Accordingly, such interest expense is not included in the computations of the ratio of earnings to fixed charges.

(c) Other fixed charges consist of the interest factor in rentals.

(d) Operating income for the year ended December 31, 2010 is presented after giving effect to (i) a restructuring charge of $87,108, (ii) a charge of $24,860 relating to the amendment of Lazard’s retirement policy with respect to RSU awards and (iii) benefits pursuant to the tax receivable agreement of $8,834 relating to the aforementioned items (see Notes 16, 18, and 19 of Notes to Consolidated Financial Statements). Excluding the impact of such items, the ratio of earnings to fixed charges would have been 3.96.

(e) Operating loss for the year ended December 31, 2009 is presented after giving effect to (i) a restructuring charge of $62,550, (ii) the acceleration of amortization expense of $86,514 relating to the vesting of RSUs held by Lazard’s former Chairman and Chief Executive Officer as the result of his death in October 2009 and (iii) the acceleration of amortization expense of $60,512 relating to the accelerated vesting of the unamortized portion of previously awarded deferred cash incentive awards (see Notes 16 and 18 of Notes to Consolidated Financial Statements). Excluding the impact of such items, the ratio of earnings to fixed charges would have been 1.21.

(f) Operating income for the year ended December 31, 2008 is presented after giving effect to a charge of $199,550 relating to the LAM Merger. Excluding the impact of such charge, the ratio of earnings to fixed charges would have been 2.40.

[1] During the year ended December 31, 2010, the Company repurchased $10,000 principal amount of the 7.125% Senior Notes, at a cost, excluding accrued interest, of $10,375, and, after the write-off of applicable unamortized debt issuance costs of $49, the Company recognized a pre-tax loss of $424. In connection with the issuance of the 7.125% Senior Notes, on April 1, 2005, Lazard Group entered into an interest rate forward agreement. On May 9, 2005, Lazard Group settled the interest rate forward agreement, of which $11,003 was deemed to be the effective portion of the hedge and recorded within AOCI and is being amortized as a charge to interest expense over the ten-year term of the 7.125% Senior Notes.

[2] During the year ended December 31, 2009, the Company repurchased $900 principal amount of the 6.85% Senior Notes, at a cost, excluding accrued interest, of $635, and, after the write-off of applicable unamortized debt issuance costs of $7, the Company recognized a pre-tax gain of $258.

[3] On April 29, 2010, Lazard Group entered into a $150,000, three-year senior revolving credit facility with a group of lenders (the "Credit Facility"). The Credit Facility, as amended, replaced the prior revolving credit facility, which was terminated as a condition to effectiveness of the Credit Facility. Interest rates under the Credit Facility vary and are based on either a Federal Funds rate or a Eurodollar rate, in each case plus an applicable margin. As of December 31, 2011, the annual interest rate for a loan accruing interest (based on the Federal Funds overnight rate), including the applicable margin, was 1.90%. At December 31, 2011 and 2010, no amounts were outstanding under the Credit Facility.

Employee Benefit Plans [Abstract]

Employee Benefit Plans

17. EMPLOYEE BENEFIT PLANS

The Company provides retirement and other post-retirement benefits to certain of its employees through defined contribution and defined benefit pension plans and other post-retirement plans. These plans generally provide benefits to participants based on average levels of compensation. Expenses related to the Company's employee benefit plans are included in "compensation and benefits" expense on the consolidated statements of operations.

The Company also offers a partially funded contributory post-retirement medical plan covering qualifying U.S. employees (the "Medical Plan"). The Medical Plan pays a stated percentage of most necessary medical expenses incurred by retirees, after subtracting payments by Medicare or other providers and after stated deductibles have been met. Participants become eligible for benefits if they retire from the Company after meeting certain age and service requirements. Effective January 1, 2005, post-retirement health care benefits are no longer offered to those managing directors and employees hired on or after January 1, 2005 and for those managing directors and employees hired before January 1, 2005 who did not attain the age of 40 before December 31, 2005. In addition, effective January 1, 2006, the cost sharing policy changed for those who qualify for the benefit. The plan was amended effective January 1, 2008, such that previously ineligible managing directors and employees who meet the Medical Plan's age and service requirements have the ability, upon retirement, to elect to purchase medical coverage through the Medical Plan at no cost to the Company. The Company will continue to contribute towards the cost of retiree medical premiums for those employees hired before January 1, 2005 who were age 55 or older on or before December 31, 2005.

Employer Contributions to Pension Plans—The Company's funding policy for its U.S. and non-U.S. pension plans is to fund when required or when applicable upon an agreement with the plans' Trustees. Management also evaluates from time to time whether to make voluntary contributions to the plans. The Company did not make any contributions to the U.S. pension plans during the year ended December 31, 2011, however it expects to make a contribution of approximately $700 to the U.S. pension plans in the year ending December 31, 2012.

In accordance with agreements reached with the Trustees of certain U.K. pension plans in 2005, the Company was obligated to make further contributions to such pension plans based upon the cumulative performance of the plans' assets against specific benchmarks as measured on June 1, 2009 and subsequently remeasured on June 1, 2010. As of December 31, 2009, the obligation related to the cumulative underperformance of the plans' assets (the "underperformance obligation") was payable in equal monthly installments through May 2013. During the year ended December 31, 2010, the Company contributed approximately $8,600 to settle the plans' underperformance obligation in full.

Further on June 30, 2009 the Company and the Trustees concluded the December 31, 2007 triennial valuation of the U.K. pension plans discussed above, pursuant to which the Company agreed to annual future contributions to the plan through 2018. The agreement also required the Company to secure its obligations' to the pension plans by placing in escrow 12.5 million British pounds (with the Company depositing such amount in escrow in July 2009), with a final redemption date of December 31, 2018. The aggregate escrow balance at December 31, 2010 had been recorded in "cash deposited with clearing organizations and other segregated cash" and "investments" on the accompanying consolidated statement of financial condition. The terms of this agreement were subject to adjustment based on the results of the December 31, 2010 triennial valuation and subsequent triennial valuations.

During 2011, the Company and the Trustees of the U.K. pension plans referred to above commenced negotiations regarding the terms of the December 31, 2010 triennial valuations of the plans and potential future contributions to the plans. We currently anticipate that the valuations will be concluded by March 31, 2012, with a tentative agreement having been reached in principle that would supersede the June 2009 agreement described above and that provides pension funding terms whereby the Company: (i) made a contribution in December 2011 to the plans of 2.3 million British pounds ($3,687 at December 31, 2011 exchange rates) from the escrow account, (ii) will make contributions of 1 million British pounds during each year from 2012 through 2020 inclusive and (iii) will amend and extend the existing escrow arrangement into an account security arrangement covering 10 million British pounds from the existing escrow and additional contributions of 1 million British pounds into such account security arrangement during each year from 2014 through 2020, inclusive, with an agreement that assets from the account security arrangements will be released into the plans if and to the extent that the value of the plans' assets falls short of the funding target for June 1, 2020 that has been agreed upon with the Trustees. The terms of the tentative agreement are subject to adjustment based on the results of subsequent triennial valuations. Additionally, the Company is discussing with the Trustees the extent to which the Company would contribute to the plans to cover their administrative expenses. The aggregate escrow balance at December 31, 2011 has been recorded in "cash deposited with clearing organizations and other segregated cash" on the accompanying consolidated statement of financial condition. Income on the escrow balance accretes to the Company and is recorded in interest income.

Additionally, during the year ended December 31, 2011, contributions made to other non-U.S. pension plans amounted to $4,867. The Company expects to contribute a similar amount to these other non-U.S. pension plans in the year ending December 31, 2012.

The following table summarizes the changes in the benefit obligations, the fair value of the assets, the funded status and amounts recognized in the consolidated statements of financial condition for the U.S. and non-U.S. defined benefit pension plans and the U.S. post-retirement Medical Plan. The Company uses December 31 as the measurement date for its employee benefit plans.

The amounts in AOCI on the consolidated statement of financial condition as of December 31, 2011 that are expected to be recognized as components of net periodic benefit cost (credit) for the year ending December 31, 2012 are as follows:

	Pension Plans		Post-Retirement Medical Plan		Total
Prior service cost	$	2,772	$	–	$	2,772
Net actuarial loss	$	1,504	$	–	$	1,504

The assumptions used to develop actuarial present value of the projected benefit obligation and net periodic pension cost as of or for the years ended December 31, 2011, 2010 and 2009 are set forth below:

	Pension Plans December 31,									Post-Retirement Medical Plan December 31,
	2011			2010			2009			2011			2010		2009
Weighted average assumptions used to determine benefit obligations:
Discount rate		4.8	%		5.4	%		5.7	%		4.1	%		5.0%		5.6%
Weighted average assumptions used to determine net periodic benefit cost:
Discount rate		4.7	%		5.0	%		5.5	%		5.0	%		5.6%		5.8%
Expected long-term rate of return on plan assets		5.4	%		5.9	%		6.2	%		–			–		–
Healthcare cost trend rates used to determine net periodic benefit cost:
Initial											8.0	%		8.5%		9.0%
Ultimate											6.0	%		6.0%		6.0%
Year ultimate trend rate achieved											2015			2015		2015

Generally, the Company determined the discount rates for its defined benefit plans by utilizing indices for long-term, high-quality bonds and ensuring that the discount rate does not exceed the yield reported for those indices after adjustment for the duration of the plans' liabilities.

In selecting the expected long-term rate of return on plan assets, the Company considered the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of the plan, giving consideration to expected returns on different asset classes held by the plans in light of prevailing economic conditions as well as historic returns. This basis is consistent for all years presented.

The assumed cost of healthcare has an effect on the amounts reported for the Company's post-retirement plans. A 1% change in the assumed healthcare cost trend rate would increase (decrease) our cost and obligation as follows:

	1% Increase				1% Decrease
	2011		2010		2011			2010
Cost	$	66	$	39	$	(49	)	$	(34	)
Obligation	$	929	$	1,231	$	(649	)	$	(891	)

Expected Benefit Payments—The following table summarizes the expected benefit payments for the Company's plans for each of the next five fiscal years and in the aggregate for the five fiscal years thereafter:

	Pension Plans		Post-Retirement Medical  Plan
2012	$	21,055	$	360
2013		21,466		393
2014		22,327		391

Activity in the fair value of the plans' Level 3 debt mutual funds for the year ended December 31, 2011 consisted of purchases and net unrealized/realized gains of $1,837 and $3, respectively, partially offset by unfavorable foreign currency translation adjustments of $63.

At December 31, 2011 and 2010, the Company's U.S. pension plans had 46% and 52%, respectively, of the plans' assets invested in exchange-traded mutual funds that invest in equity securities and 54% and 48%, respectively, invested in an exchange-traded mutual fund that invests in debt securities, both of which are categorized as Level 1. The Company's non-U.S. pension plans at December 31, 2011 and 2010 had 36% and 43%, respectively, of the plans' assets invested in certain debt mutual funds which are categorized as Level 2. The Company's other non-U.S. pension plans' investment holdings did not individually constitute more than 10% of non-U.S. pension plan assets at December 31, 2011 and 2010.

Investment Policies and Strategies—The primary investment goal is to ensure that the plans remain well funded, taking account of the likely future risks to investment returns and contributions. As a result, a portfolio of assets is maintained with appropriate liquidity and diversification that can be expected to generate long-term future returns that minimize the long-term costs of the pension plans without exposing the trust to an unacceptable risk of under-funding. The Company's likely future ability to pay such contributions as are required to maintain the funded status of the plans over a reasonable time period is considered when determining the level of risk that is appropriate. The fair values of plan investments classified as Level 1 assets are based on market quotes. The fair values of plan assets classified as Level 2 assets are primarily based on information provided by fund managers.

Defined Contribution Plans—Pursuant to certain matching contributions, the Company contributes to employer sponsored defined contribution plans. Such contributions amounted to $10,944, $9,684 and $8,409 for the years ended December 31, 2011, 2010 and 2009, respectively, which are included in "compensation and benefits" expense on the consolidated statements of operations.

Organization And Basis Of Presentation

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

Lazard Ltd, a Bermuda holding company, and its subsidiaries (collectively referred to as "Lazard Ltd", "Lazard", "we" or the "Company"), including Lazard Ltd's indirect investment in Lazard Group LLC, a Delaware limited liability company (collectively referred to, together with its subsidiaries, as "Lazard Group"), is one of the world's preeminent financial advisory and asset management firms and has long specialized in crafting solutions to the complex financial and strategic challenges of our clients. We serve a diverse set of clients around the world, including corporations, partnerships, institutions, governments and high net worth individuals.

Lazard Ltd indirectly held approximately 94.8% and 94.0% of all outstanding Lazard Group common membership interests as of December 31, 2011 and 2010, respectively. Lazard Ltd, through its control of the managing members of Lazard Group, controls Lazard Group. LAZ-MD Holdings LLC ("LAZ-MD Holdings"), an entity owned by Lazard Group's current and former managing directors, held approximately 5.2% and 6.0% of the outstanding Lazard Group common membership interests as of December 31, 2011 and 2010, respectively. Additionally, LAZ-MD Holdings was the sole owner of the one issued and outstanding share of Lazard Ltd's Class B common stock (the "Class B common stock") which provided LAZ-MD Holdings with approximately 5.2% and 6.0% of the voting power but no economic rights in the Company as of December 31, 2011 and 2010, respectively. Subject to certain limitations, LAZ-MD Holdings' interests in Lazard Group are exchangeable for Lazard Ltd Class A common stock, par value $0.01 per share ("Class A common stock"). Lazard Group is governed by an Operating Agreement dated as of May 10, 2005, as amended (the "Operating Agreement").

Our sole operating asset is our indirect ownership of common membership interests of Lazard Group and our managing member interest of Lazard Group, whose principal operating activities are included in two business segments:

• Financial Advisory, which offers corporate, partnership, institutional, government, sovereign and individual clients across the globe a wide array of financial advisory services regarding mergers and acquisitions ("M&A") and other strategic matters, restructurings, capital structure, capital raising and various other financial matters, and

• Asset Management, which includes strategies for the management of equity and fixed income securities and alternative investment and private equity funds, as well as wealth management.

In addition, we record selected other activities in our Corporate segment, including management of cash, certain investments and the commercial banking activities of Lazard Group's Paris-based Lazard Frères Banque SA ("LFB"). We also allocate outstanding indebtedness to our Corporate segment.

LFB is a registered bank regulated by the Autorité de Contrôle Prudentiel. It is engaged primarily in commercial and private banking services for clients and funds managed by Lazard Frères Gestion SAS ("LFG") and other clients, investment banking activities, including participation in underwritten offerings of securities in France, asset-liability management and limited trading in securities and foreign exchange.

Basis of Presentation

The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The Company's policy is to consolidate (i) entities in which it has a controlling financial interest, (ii) variable interest entities ("VIEs") where the Company has a variable interest and is deemed to be the primary beneficiary and (iii) limited partnerships where the Company is the general partner, unless the presumption of control is overcome. When the Company does not have a controlling interest in an entity, but exerts significant influence over the entity's operating and financial decisions, the Company applies the equity method of accounting in which it records in earnings its share of earnings or losses of the entity. Intercompany transactions and balances have been eliminated.

The consolidated financial statements include Lazard Ltd, Lazard Group and Lazard Group's principal operating subsidiaries: Lazard Frères & Co. LLC ("LFNY"), a New York limited liability company, along with its subsidiaries, including Lazard Asset Management LLC and its subsidiaries (collectively referred to as "LAM"); its French limited liability companies Compagnie Financière Lazard Frères SAS ("CFLF") along with its subsidiaries, LFB and LFG, and Maison Lazard SAS and its subsidiaries; and Lazard & Co., Limited ("LCL"), through Lazard & Co., Holdings Limited, an English private limited company ("LCH"), together with their jointly owned affiliates and subsidiaries.

LFCM Holdings

LFCM Holdings owns and operates the capital markets business and fund management activities, as well as other specified non-operating assets and liabilities, that were transferred to it by Lazard Group (referred to as the "separated businesses") in May 2005 and is owned by various current and former working members, including certain of Lazard's current and former managing directors (which also include certain of the Company's executive officers) who were or are also members of LAZ-MD Holdings. In addition to the master separation agreement, dated as of May 10, 2005, by and among Lazard Ltd, Lazard Group, LAZ-MD Holdings and LFCM Holdings (the "master separation agreement"), which effected the separation and recapitalization that occurred in May 2005, LFCM Holdings entered into an insurance matters agreement and a license agreement that addressed various business matters associated with the separation, as well as several other agreements discussed below.

Under the employee benefits agreement, dated as of May 10, 2005, by and among Lazard Ltd, Lazard Group, LAZ-MD Holdings and LFCM Holdings, LFCM Holdings generally assumed, as of the completion of the separation and recapitalization transactions, all outstanding and future liabilities in respect of the current and former employees of the separated businesses. The Company retained all accrued liabilities under, and assets of, the pension plans in the U.S. and the U.K. as well as the 401(k) plan accounts of the inactive employees of LFCM Holdings and its subsidiaries.

Pursuant to the administrative services agreement, dated as of May 10, 2005, by and among LAZ-MD Holdings, LFCM Holdings and Lazard Group (the "administrative services agreement"), Lazard Group provides selected administrative and support services to LAZ-MD Holdings and LFCM Holdings, such as cash management and debt service administration, accounting and financing activities, tax, payroll, human resources administration, financial transaction support, information technology, public communications, data processing, procurement, real estate management and other general administrative functions. Lazard Group charges for these services based on Lazard Group's cost allocation methodology.

The services provided pursuant to the administrative services agreement by Lazard Group to LFCM Holdings, and by LFCM Holdings to Lazard Group, are subject to automatic annual renewal, unless either party gives 180 days' notice of termination. LFCM Holdings and Lazard Group have a right to terminate the services earlier if there is a change of control of either party or the business alliance provided in the business alliance agreement entered into on May 10, 2005, by and among LAZ-MD Holdings, LFCM Holdings and Lazard Group (the "business alliance agreement") (described below) expires or is terminated. The party receiving a service may also terminate a service earlier upon 180 days' notice as long as the receiving party pays the service provider an additional three months of service fee for the terminated service. In addition, in connection with the various agreements entered into regarding the CP II MgmtCo Spin-Off described below, Lazard Group agreed to provide certain specified services to LFCM Holdings (which, in turn, LFCM Holdings may provide to its subsidiary, CP II MgmtCo ("CP II MgmtCo")).

The business alliance agreement provides, among other matters, that Lazard Group will refer to LFCM Holdings selected opportunities for underwriting and distribution of securities. In addition, Lazard Group will provide assistance in the execution of any such referred business. In exchange for the referral obligation and assistance, Lazard Group will receive a referral fee from LFCM Holdings equal to approximately one-half of the revenue obtained by LFCM Holdings in respect of any underwriting or distribution opportunity. In addition, LFCM Holdings will refer opportunities in the Financial Advisory and Asset Management businesses to Lazard Group. In exchange for this referral, LFCM Holdings will be entitled to a customary finders' fee from Lazard Group. The business alliance agreement further provides that, during the term of the business alliance, LFNY and Lazard Asset Management Securities LLC, an indirect wholly-owned subsidiary of LFNY, will introduce execution and settlement transactions to broker-dealer entities affiliated with LFCM Holdings. The business alliance agreement is subject to periodic automatic renewal, unless Lazard Group or LFCM Holdings elects to terminate the agreement in connection with any such renewal or elects to terminate on account of a change of control of either party.

For the years ended December 31, 2011, 2010 and 2009, amounts recorded by Lazard Group relating to the administrative services agreement amounted to $10,277, $12,110 and $9,717, respectively, and net referral fees for underwriting, private placement, M&A and restructuring transactions under the business alliance agreement amounted to $18,862, $11,506 and $12,301, respectively. Amounts relating to the administrative services agreement are reported as reductions to operating expenses. Net referral fees for underwriting transactions under the business alliance agreement are reported in "revenue-other". Net referral fees for private placement, M&A and restructuring transactions under the business alliance agreement are reported in advisory fee revenue.

Receivables from LFCM Holdings and its subsidiaries as of December 31, 2011 and 2010 primarily include $10,722 and $12,775, respectively, related to administrative and support services and reimbursement of expenses incurred on behalf of LFCM Holdings, and $2,928 and $11,413, respectively, related to referral fees for underwriting and private placement transactions. Payables to LFCM Holdings and its subsidiaries at December 31, 2011 and 2010 relate primarily to obligations pursuant to the tax receivable agreement of $2,790 and $2,361, respectively (see Note 19 of Notes to Consolidated Financial Statements) and $2,060 and $458, respectively, principally relating to certain advances and referral fees for Financial Advisory transactions.

Other

For the years ended December 31, 2011 and 2010, amounts recorded by Lazard Group relating to referral fees for restructuring transactions and fee sharing with MBA Lazard Holdings S.A. Group ("MBA"), an Argentina-based group in which the Company has a 50% ownership interest, amounted to $1,866 and $128, respectively, and are reported in advisory fee revenue. There were no such amounts for the year ended December 31, 2009.

Other receivables at December 31, 2011 and 2010 and payables at December 31, 2011 primarily relate to referral fees for restructuring and M&A transactions with MBA and, in 2011, a related party loan.

LAZ-MD Holdings

Lazard Group provides selected administrative and support services to LAZ-MD Holdings through the administrative services agreement as discussed above, with such services generally to be provided until December 31, 2014 unless terminated earlier because of a change in control of either party. Lazard Group charges LAZ-MD Holdings for these services based on Lazard Group's cost allocation methodology and, for the years ended December 31, 2011, 2010 and 2009, such charges amounted to $750 in each year.

Lazard Alternative Investments

The business alliance agreement, among other things, granted Lazard Group the option to acquire the North American and European fund management activities of Lazard Alternative Investments Holdings LLC ("LAI"), the subsidiary of LFCM Holdings that owns and operates LFCM Holdings' alternative investment (including private equity) activities, for an aggregate purchase price of $8,000 and $2,000, respectively. On December 15, 2009, Lazard Group exercised its option to acquire the European fund management activities of LAI for a purchase price of $2,000. LAI's fund management activities consist of the fund management and general partner entities, together with Lazard Group's direct investments in related funds that were transferred to LFCM Holdings pursuant to or in anticipation of the May 10, 2005 separation (the "separation") from the Company of its former Capital Markets and Other business segment.

The business alliance agreement provides Lazard Group with certain governance rights with respect to LAI and provides for support by LFCM Holdings of the business of LAI. With respect to historical investments and funds transferred to LFCM Holdings as part of the separation, profits realized prior to the exercise of the option are for the account of LFCM Holdings, whereas profits realized after the exercise of the option are for the account of Lazard Group. The master separation agreement and business alliance agreement provide for Lazard Group (i) to invest capital in future funds to be managed by LFCM Holdings' subsidiaries and (ii) to receive incentive distributions from such funds, as well as profits related to such investments, if any, irrespective of whether it exercises its purchase option.

In February 2005, Lazard Group formed CP II, with institutional and Lazard Group capital commitments which required funding at any time through 2010, except for potential follow-on investments and/or CP II expenses. As of December 31, 2011, Lazard Group's investment in CP II amounted to $31,533 which is recorded within "investments - other - private equity" on the consolidated statement of financial condition. Pursuant to the master separation agreement and business alliance agreement, CP II was managed by CP II MgmtCo, and Lazard Group is entitled to receive the carried interest distributions made by CP II (other than the carried interest distributions made to investment professionals who manage the fund).

In February 2009, pursuant to agreements entered into by the Company with a subsidiary of LAI ("LAI North America"), LFCM Holdings and the investment professionals who manage CP II, equity ownership of CP II MgmtCo was transferred from LAI North America to the investment professionals who manage CP II (the "CP II MgmtCo Spin-Off"). Concurrently with the CP II MgmtCo Spin-Off, CP II MgmtCo became a standalone entity. In addition, in connection with a February 2009 $4,000 cash payment from Lazard Group to LFCM Holdings relating to the CP II MgmtCo Spin-Off, the business alliance agreement was amended to remove any restriction on the Company engaging in private equity businesses in North America other than certain investments in real estate and technology and information services. Such amendment reduced the then purchase price relating to our option to acquire the fund management activities of LAI in North America from $6,500 to $2,500. As part of the CP II MgmtCo Spin-Off, we retained our entitlement to receive a slightly reduced portion of the carried interest distributions made by CP II.

The remaining option to purchase the North American fund management activities is currently exercisable at any time prior to May 10, 2014, for a purchase price of $2,500 as described above. The reduced price for the North American option reflects (i) a reduction of $1,500 due to the payment of a like amount in February 2008 to LFCM Holdings in connection with the Sapphire IPO, whereby LFCM Holdings agreed not to assert certain claims that it may believe that it had under the business alliance agreement and (ii) the $4,000 payment described above.

During the fourth quarter of 2011, the Company determined that it was unlikely to exercise the North American option. Accordingly, during such period the Company wrote-off the $5,500 capitalized cost associated with the option which is included within "other" operating expenses on the consolidated statement of operations.

Regulatory Authorities

22. REGULATORY AUTHORITIES

LFNY is a U.S. registered broker-dealer and is subject to the net capital requirements of Rule 15c3-1 under the Exchange Act. Under the basic method permitted by this rule, the minimum required net capital, as defined, is a specified fixed percentage of total aggregate indebtedness recorded in LFNY's Financial and Operational Combined Uniform Single ("FOCUS") report filed with the Financial Industry Regulatory Authority ("FINRA"), or $100, whichever is greater. At December 31, 2011, LFNY's regulatory net capital was $100,819, which exceeded the minimum requirement by $93,184.

Certain U.K. subsidiaries of the Company, including LCL, Lazard Fund Managers Limited and Lazard Asset Management Limited (the "U.K. Subsidiaries") are authorized and regulated by the Financial Services Authority. At December 31, 2011, the aggregate regulatory net capital of the U.K. Subsidiaries was $149,345, which exceeded the minimum requirement by $137,437.

CFLF, under which asset management and commercial banking activities are carried out in France, is subject to regulation by the Autorité de Contrôle Prudentiel for its banking activities conducted through its subsidiary, LFB. In addition, the investment services activities of the Paris group, exercised through LFB and other subsidiaries of CFLF, primarily LFG (asset management), are subject to regulation and supervision by the Autorité des Marchés Financiers. At December 31, 2011, the consolidated regulatory net capital of CFLF was $175,781, which exceeded the minimum requirement set for regulatory capital levels by $81,099.

Certain other U.S. and non-U.S. subsidiaries are subject to various capital adequacy requirements promulgated by various regulatory and exchange authorities in the countries in which they operate. At December 31, 2011, for those subsidiaries with regulatory capital requirements, their aggregate net capital was $96,255, which exceeded the minimum required capital by $71,592.

At December 31, 2011, each of these subsidiaries individually was in compliance with its regulatory capital requirements.

Lazard Ltd had been subject to supervision by the SEC as a Supervised Investment Bank Holding Company ("SIBHC"). As a SIBHC, Lazard Ltd was subject to group-wide supervision, which required it to compute allowable capital and risk allowances on a consolidated basis. However, pursuant to Section 617 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), the SEC's SIBHC program was eliminated on July 21, 2011. Pursuant to relevant rules in the European Union, Lazard Ltd is required to be supervised by another regulatory body, either in the U.S. or the European Union. The Dodd-Frank Act allows certain securities holding companies seeking consolidated supervision, including Lazard Ltd, to elect to be supervised by the Board of Governors of the Federal Reserve. Lazard Ltd anticipates that the Board of Governors of the Federal Reserve will adopt regulations pursuant to Section 618 of the Dodd-Frank Act in the near future for companies that seek to come under its consolidated supervision. Once it analyzes the final scope of such regulations, Lazard Ltd will determine whether it will elect to register to come under the consolidated supervision of the Federal Reserve. Until such regulations are adopted, however, we cannot determine the full impact of such regulations on us. The Dodd-Frank Act and the rules and regulations that may be adopted thereunder (including regulations that have not yet been proposed) could have other effects on us. We continue to monitor the process as such rules are proposed and adopted.

Segment Information

23. SEGMENT INFORMATION

The Company's reportable segments offer different products and services and are managed separately as different levels and types of expertise are required to effectively manage the segments' transactions. Each segment is reviewed to determine the allocation of resources and to assess its performance. The Company's principal operating activities are included in two business segments as described in Note 1 above - Financial Advisory and Asset Management. In addition, as described in Note 1 above, the Company records selected other activities in its Corporate segment.

The Company's segment information for the years ended December 31, 2011, 2010 and 2009 is prepared using the following methodology:

• Revenue and expenses directly associated with each segment are included in determining operating income.

• Expenses not directly associated with specific segments are allocated based on the most relevant measures applicable, including headcount, square footage and other factors.

• Segment assets are based on those directly associated with each segment, and include an allocation of certain assets relating to various segments, based on the most relevant measures applicable, including headcount, square footage and other factors.

The Company allocates investment gains and losses, interest income and interest expense among the various segments based on the segment in which the underlying asset or liability is reported.

Each segment's operating expenses include (i) compensation and benefits expenses incurred directly in support of the businesses and (ii) other operating expenses, which include directly incurred expenses for occupancy and equipment, marketing and business development, technology and information services, professional services, fund administration and outsourced services and indirect support costs (including compensation and other operating expenses related thereto) for administrative services. Such administrative services include, but are not limited to, accounting, tax, legal, facilities management and senior management activities.

There were no clients for the years ended December 31, 2011, 2010 and 2009 that individually constituted more than 10% of the net revenue of any of the Company's business segments.

Management evaluates segment results based on net revenue and operating income and believes that the following information provides a reasonable representation of each segment's contribution with respect to net revenue, operating income (loss) and total assets:

Commitments And Contingencies

14. COMMITMENTS AND CONTINGENCIES

Leases—The Company leases office space and equipment under non-cancelable lease agreements, which expire on various dates through 2033.

Operating lease agreements, in addition to base rentals, generally are subject to escalation provisions based on certain costs incurred by the landlord. For the years ended December 31, 2011, 2010 and 2009, aggregate rental expense relating to operating leases amounted to $76,718, $66,350 and $69,412, respectively, and is included in "occupancy and equipment" or "technology and information services" on the consolidated statements of operations, depending on the nature of the underlying asset. The Company subleases office space under agreements, which expire on various dates through 2033. Sublease income from such agreements was $10,967, $10,478, and $11,327 for the years ended December 31, 2011, 2010 and 2009, respectively.

Capital lease obligations recorded under sale/leaseback transactions are payable through 2017 at a weighted average interest rate of approximately 6.4%. Such obligations are collateralized by certain buildings with a net book value of approximately $22,491 and $25,004 at December 31, 2011 and 2010, respectively. The net book value of all assets recorded under capital leases aggregated $24,589 and $27,767 at December 31, 2011 and 2010, respectively.

At December 31, 2011, minimum rental commitments under non-cancelable leases, net of sublease income, are approximately as follows:

Year Ending December 31,	Minimum Rental Commitments

With respect to abandoned leased facilities in the U.K., at December 31, 2011 and 2010, the Company has recognized liabilities of $10,632 and $7,194, respectively, which are included in "other liabilities" on the consolidated statements of financial condition. Payments toward the liabilities continue through the remaining term of the leases. Such liabilities are based on the discounted future commitment, net of expected sublease income. During the year ended December 31, 2011, the Company recorded a charge of $5,539 related to such abandoned lease facilities, which is included within "occupancy and equipment" on the consolidated statement of operations.

Guarantees—In the normal course of business, LFB provides indemnifications to third parties to protect them in the event of non-performance by its clients. At December 31, 2011, LFB had $3,907 of such indemnifications and held $2,655 of collateral/counter-guarantees to secure these commitments. The Company believes the likelihood of loss with respect to these indemnities is remote. Accordingly, no liability is recorded in the consolidated statement of financial condition.

Other Commitments—In the normal course of business, LFB enters into commitments to extend credit, predominately at variable interest rates. Such commitments at December 31, 2011 aggregated $15,647. These commitments have varying expiration dates and are fully collateralized and generally contain requirements for the counterparty to maintain a minimum collateral level. These commitments may not represent future cash requirements as they may expire without being drawn upon.

See Notes 6, 8, 9 and 17 of Notes to Consolidated Financial Statements for information regarding commitments relating to investment capital funding commitments, the LAM Merger, business acquisitions and obligations to fund our pension plans, respectively.

The Company has various other contractual commitments arising in the ordinary course of business. In addition, from time to time, LFB enters into underwriting commitments in which it participates as a joint underwriter. The settlement of such transactions are not expected to have a material adverse effect on the Company's consolidated financial position or results of operations. At December 31, 2011, LFB had no such underwriting commitments.

In the opinion of management, the fulfillment of the commitments described herein will not have a material adverse effect on the Company's consolidated financial position or results of operations.

Legal—The Company is involved from time to time in judicial, regulatory and arbitration proceedings and inquiries concerning matters arising in connection with the conduct of our businesses, including proceedings initiated by former employees alleging wrongful termination. The Company reviews such matters on a case-by-case basis and establishes any required accrual if a loss is probable and the amount of such loss can be reasonably estimated. The Company does experience significant variation in its revenue and earnings on a quarterly basis. Accordingly, the results of any pending matter or matters could be significant when compared to the Company's earnings in any particular fiscal quarter. The Company believes, however, based on currently available information, that the results of any pending matters, in the aggregate, will not have a material effect on its business or financial condition.

16. INCENTIVE PLANS

Share-Based Incentive Plan Awards

A description of Lazard Ltd's 2005 Plan and 2008 Plan and activity with respect thereto during the years ended December 31, 2011, 2010 and 2009, is presented below.

Shares Available Under the 2005 Plan and 2008 Plan

The 2005 Plan authorizes the issuance of up to 25,000,000 shares of Class A common stock pursuant to the grant or exercise of stock options, stock appreciation rights, restricted stock, stock units and other equity-based awards. Each stock unit granted under the 2005 Plan represents a contingent right to receive one share of Class A common stock, at no cost to the recipient. The fair value of such stock unit awards is determined based on the closing market price of Class A common stock at the date of grant.

In addition to the shares available under the 2005 Plan, additional shares of Class A common stock are available under the 2008 Plan. The maximum number of shares available under the 2008 Plan is based on a formula that limits the aggregate number of shares that may, at any time, be subject to awards that are considered "outstanding" under the 2008 Plan to 30% of the then-outstanding shares of Class A common stock (treating, for this purpose, the then-outstanding exchangeable interests of LAZ-MD Holdings on a "fully-exchanged" basis as described in the 2008 Plan).

Restricted and Deferred Stock Units

RSUs generally require future service as a condition for the delivery of the underlying shares of Class A common stock (unless the recipient is then eligible for retirement under the Company's retirement policy) and convert into Class A common stock on a one-for-one basis after the stipulated vesting periods. The grant date fair value of the RSUs, net of an estimated forfeiture rate, is amortized over the vesting periods or requisite service periods, and, for purposes of calculating diluted net income per share, are included in the diluted weighted average shares of Class A common stock outstanding using the treasury stock method. Expense relating to RSUs was as follows within the Company's consolidated statements of operations:

	Year Ended December 31,
	2011		2010		2009
Compensation and benefits (*)	$	264,110	$	256,214	$	333,823
Restructuring		–		46,880		24,239
Total	$	264,110	$	303,094	$	358,062

(*) Includes, during the year ended December 31, 2010, $24,860 relating to the amendment of the Company's retirement policy (described below) and, during the year ended December 31, 2009, $86,514 of accelerated amortization expense relating to awards held by Lazard's former Chairman and Chief Executive Officer as a result of his death.

RSUs issued subsequent to December 31, 2005 generally include a dividend participation right that provides that during vesting periods each RSU is attributed additional RSUs (or fractions thereof) equivalent to any ordinary quarterly dividends paid on Class A common stock during such period. During the years ended December 31, 2011, 2010 and 2009, issuances of RSUs pertaining to such dividend participation rights and respective charges to "retained earnings", net of estimated forfeitures, (with corresponding credits to "additional paid-in-capital") consisted of the following:

	Year Ended December 31,
	2011		2010		2009
Number of RSUs issued		389,846		318,025		331,642
Charges to retained earnings, net of estimated forfeitures	$	11,120	$	9,522	$	4,042

In January 2010, the Company amended its retirement policy with respect to RSU awards. Such amendment served to modify the retirement eligibility vesting requirements of existing and future RSU awards, and, as noted above, Lazard accelerated the recognition of compensation expense for the affected RSU awards. Accordingly, the Company recorded a non-cash charge to "compensation and benefits" expense of $24,860 in the first quarter of 2010 relating to prior years' awards.

Non-executive members of the Board of Directors receive approximately 55% of their annual compensation for service on the Board of Directors and its committees in the form of DSUs, which resulted in 26,859, 31,588 and 36,627 DSUs granted during the years ended December 31, 2011, 2010 and 2009, respectively. Their remaining compensation is payable in cash, which they may elect to receive in the form of additional DSUs under the Directors' Fee Deferral Unit Plan described below. DSUs are convertible into Class A common stock at the time of cessation of service to the Board. The DSUs include a cash dividend participation right equivalent to any ordinary quarterly dividends paid on Class A common stock, and resulted in nominal cash payments for the years ended December 31, 2011, 2010 and 2009.

On May 9, 2006, the Board of Directors adopted the Directors' Fee Deferral Unit Plan, which allows the Company's Non-Executive Directors to elect to receive additional DSUs pursuant to the 2005 Plan in lieu of some or all of their cash fees. The number of DSUs that shall be granted to a Non-Executive Director pursuant to this election will equal the value of cash fees that the applicable Non-Executive Director has elected to forego pursuant to such election, divided by the market value of a share of Class A common stock on the date on which the foregone cash fees would otherwise have been paid. During the years ended December 31, 2011, 2010 and 2009, 8,184, 7,438 and 8,899 DSUs, respectively, had been granted pursuant to such Plan.

DSU awards are expensed at their fair value on their date of grant, which, inclusive of amounts related to the Directors' Fee Deferral Unit Plan, totaled $1,265, $1,230 and $1,316 during the years ended December 31, 2011, 2010 and 2009, respectively.

The following is a summary of activity relating to RSUs and DSUs during the three-year period ended December 31, 2011:

	RSUs					DSUs
	Units			Weighted Average Grant Date Fair Value		Units			Weighted Average Grant Date Fair Value
Balance, January 1, 2009		22,141,468		$	39.17		65,256		$	40.32

Balance, December 31, 2010		22,108,635		$	35.67		121,737		$	34.46
Granted (including 389,846 RSUs relating to dividend participation)		7,002,736		$	43.21		35,043		$	36.09
Forfeited		(305,155	)	$	37.83		–			–
Vested/Converted		(8,054,387	)	$	39.13		(16,120	)	$	34.76
Balance, December 31, 2011		20,751,829		$	36.84		140,660		$	34.83

During the years ended December 31, 2011, 2010 and 2009, 8,054,387 RSUs, 8,248,654 RSUs and 5,948,920 RSUs (including the acceleration of 4,406,440 RSUs held by Lazard's former Chairman and Chief Executive Officer as a result of his death) vested, respectively, and, during the year ended December 31, 2010, 40,895 RSUs were exchanged for 40,895 shares of restricted Class A common stock. In connection with the vested RSUs, the Company satisfied certain employees' tax obligations in lieu of issuing 2,353,561, 1,674,261 and 446,172 shares of Class A common stock in the years ended December 31, 2011, 2010 and 2009, respectively. Accordingly, 5,700,826, 6,574,393 and 5,502,748 shares of Class A common stock held by Lazard Group were delivered during the years ended December 31, 2011, 2010 and 2009, respectively.

As of December 31, 2011, unrecognized RSU compensation expense, adjusted for estimated forfeitures, was approximately $259,000, with such unrecognized compensation expense expected to be recognized over a weighted average period of approximately 1.3 years subsequent to December 31, 2011. The ultimate amount of such expense is dependent upon the actual number of RSUs that vest. The Company periodically assesses the forfeiture rates used for such estimates. A change in estimated forfeiture rates would cause the aggregate amount of compensation expense recognized in future periods to differ from the estimated unrecognized compensation expense described herein.

Restricted Stock

The following is a summary of activity related to shares of restricted Class A common stock associated with compensation arrangements during the two-year period ended December 31, 2011:

	Restricted Shares			Weighted Average Grant Date Fair Value
Balance, January 1, 2010		–			–
Granted/Exchanged (a)		95,332		$	37.63
Vested		–			–
Balance, December 31, 2010		95,332		$	37.63
Granted		327,238		$	43.70
Vested		(327,238	)	$	43.70
Balance, December 31, 2011		95,332		$	37.63

(a) Includes 40,895 shares of restricted Class A common stock issued in exchange for 40,895 RSUs previously granted during the year at a grant date fair value of $36.10 per share. The vesting terms of such restricted Class A common stock issued are the same as those of the original award exchanged. There was no incremental compensation cost incurred as a result of the exchange.

 The Company satisfied certain employees' tax obligations in lieu of delivering 68,866 shares of Class A common stock in connection with shares of restricted Class A common stock that vested during the year ended December 31, 2011. Accordingly, 258,372 shares of Class A common stock held by the Company were delivered during the year ended December 31, 2011.

Expense relating to restricted stock awards is charged to "compensation and benefits" expense within the Company's consolidated statements of operations, and amounted to $9,767 and $979 for the years ended December 31, 2011 and 2010, respectively. The awards include a cash dividend participation right equivalent to any ordinary quarterly dividends paid on Class A common stock during the period, which will vest concurrently with the underlying restricted stock award. At December 31, 2011, unrecognized restricted stock expense was approximately $957, with such expense to be recognized over a weighted average period of approximately 0.7 years subsequent to December 31, 2011.

For purposes of calculating diluted net income per share, such awards are included in the diluted weighted average shares of Class A common stock outstanding using the "treasury stock" method.

Lazard Fund Interests

As previously described, in February 2011 the Company granted to eligible employees Lazard Fund Interests. In connection with the Lazard Fund Interests and other similar deferred compensation arrangements, the Company recorded a prepaid compensation asset and a corresponding compensation liability on the grant date based upon the fair value of the award. The prepaid asset is amortized on a straight-line basis over the applicable vesting periods or requisite service periods, and is charged to "compensation and benefits" expense within the Company's consolidated statement of operations, and amounted to $14,551 for the year ended December 31, 2011. Lazard Fund Interests and similar deferred compensation arrangements that do not require future service are expensed immediately. The related compensation liability is accounted for at fair value as a derivative liability, and is adjusted for changes in fair value primarily related to the changes in the fair value of the underlying investments. Such changes in the fair value of the derivative liability are recorded to "compensation and benefits" expense within the Company's consolidated statements of operations, the impact of which equally offsets the changes in fair value of the underlying investments owned and is reported in "revenue-other" in the consolidated statement of operations (see Note 7 of Notes to Consolidated Financial Statements).

The Lazard Fund Interests granted as of December 31, 2011 generally provide for one-third vesting on March 1, 2013 and two-thirds vesting on March 3, 2014. As of December 31, 2011, unrecognized compensation expense for Lazard Fund Interests and other similar deferred compensation arrangements, adjusted for estimated forfeitures, was approximately $18,000. Such compensation expense will generally be recognized over a weighted average period of approximately 1.8 years subsequent to December 31, 2011.

Incentive Awards Granted In February 2009

A portion of the incentive awards granted in February 2009 included a deferred cash component, which was originally scheduled to vest over a maximum period of four years. During the fourth quarter of 2009, in connection with a review of the Company's compensation policy, the Company accelerated the vesting of the then unamortized portion of such previously awarded deferred cash incentive awards which resulted in a pre-tax charge to "compensation and benefits" expense of $60,512.

Incentive Awards Granted In February 2012

In February 2012, the Company granted approximately $281,000 of deferred incentive awards to eligible employees. These grants included approximately 6.1 million RSUs or shares of restricted Class A common stock, that in accordance with U.S. GAAP, were measured at the grant date fair value of $27.57 per RSU or share of restricted Class A common stock, or an aggregate of approximately $168,000. In addition, eligible employees will have the choice of receiving a portion of their deferred incentive awards in a combination of (i) Lazard Fund Interests, and (ii) additional RSUs or shares of restricted Class A common stock. The aggregate fair value on the date of grant of these awards is approximately $102,000. The remaining deferred incentive awards include deferred cash awards and a portion of fund managers' year-end incentive compensation that is reinvested in certain asset management funds. The aggregate fair value on the date of grant of these awards is approximately $11,000.

The RSUs, restricted stock and Lazard Fund Interests granted each provide for one-third vesting on March 3, 2014 and the remaining two-thirds vesting on March 2, 2015. Compensation expense with respect to such incentive awards will generally be recognized over the vesting period, with such compensation expense to be recognized over a weighted average period of approximately 2.7 years.

Business Acquisitions [Abstract]

Business Acquisitions

9. BUSINESS ACQUISITIONS

On July 15, 2009, the Company established a private equity business with Edgewater. Edgewater manages funds primarily focused on buy-out and growth equity investments in middle market companies. The acquisition was structured as a purchase by Lazard Group of interests in a holding company that in turn owns interests in the general partner and management company entities of the current Edgewater private equity funds (the "Edgewater Acquisition"). Following the Edgewater Acquisition, Edgewater's leadership team retained a substantial economic interest in such entities.

The aggregate fair value of the consideration recognized by the Company at the acquisition date was $61,624. Such consideration consisted of (i) a one-time cash payment, (ii) 1,142,857 shares of Class A common stock (the "Initial Shares") and (iii) up to 1,142,857 additional shares of Class A common stock subject to earnout criteria and payable over time (the "Earnout Shares"). The Initial Shares are subject to forfeiture provisions that lapse only upon the achievement of certain performance thresholds and transfer restrictions during the four year period ending December 2014. The Earnout Shares will be issued only if certain performance thresholds are met. On December 30, 2011, 285,715 Initial Shares and 57,287 Earnout Shares became unrestricted or were otherwise delivered.

The Edgewater Acquisition was accounted for under the acquisition method of accounting, whereby the results of the acquired business are included in our consolidated financial results from July 15, 2009, the effective date of the acquisition. As a result of the acquisition, we recorded net tangible assets, identifiable intangible assets and goodwill of $53,635 (consisting primarily of Edgewater's investments in the underlying funds and cash), $56,200 and $61,630, respectively, which include amounts for Edgewater's noncontrolling interests held (whose economic interests approximate 50%) aggregating $109,841. Goodwill pertaining to this acquisition is deductible for income tax purposes. See Note 11 of Notes to Consolidated Financial Statements for additional information relating to goodwill and other intangible assets. The operating results relating to Edgewater are included in the Company's Asset Management segment.

In prior years, the Company made certain other business acquisitions. These purchases were affected through an exchange of a combination of cash, Class A common stock, and by Lazard Ltd issuing shares of non-participating convertible Series A and Series B preferred stock, which are or were each convertible into Class A common stock. In connection with such acquisitions, as of December 31, 2011 and 2010, 47,474 and 1,295,029 shares of Class A common stock, respectively, were issuable on a non-contingent basis. Additionally, at December 31, 2010, 4,862 shares of Series A preferred stock were convertible into shares of Class A common stock on a non-contingent basis. During the year ended December 31, 2011, an additional 9,238 shares of Series A preferred stock became convertible, with the total of 14,100 shares of Series A preferred stock converting into 2,434,561 shares of Class A common stock during the year. Depending upon the future performance of such businesses acquired, at December 31, 2011 and 2010, 7,921 and 17,159 shares of Series A preferred stock were contingently convertible into shares of Class A common stock. See Note 15 of Notes to Consolidated Financial Statements for additional information relating to preferred stock.

Receivables - Net

4. RECEIVABLES - NET

The Company's "receivables - net" represents receivables from fees, customers and other and related parties.

In connection with collateralized lending activities of LFB, the Company typically receives a pledge of specifically identified securities of equal or greater value than the amount of the cash loaned. Collateralized customer loan receivables, which amounted to $5,952 and $4,009 at December 31, 2011 and 2010, respectively, were collateralized by securities of equal or greater value at each such date.

Receivables are stated net of an estimated allowance for doubtful accounts of $19,450 and $15,017 at December 31, 2011 and 2010, respectively, for past due amounts and for specific accounts deemed uncollectible, which may include situations where a fee is in dispute. The Company recorded bad debt expense of $7,952, $8,392 and $4,509 for the years ended December 31, 2011, 2010 and 2009, respectively. In addition, the Company recorded charge-offs, foreign currency translation and other adjustments, which resulted in a net decrease to the allowance for doubtful accounts of $3,519, $4,950 and $8,817 for the years ended December 31, 2011, 2010 and 2009, respectively. At December 31, 2011 and 2010, the Company had receivables deemed past due or uncollectible of $22,785 and $17,101, respectively.

3. RECENT ACCOUNTING DEVELOPMENTS

Fair Value Measurements—During May 2011, the FASB amended its fair value measurement guidance, which it states was designed to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards ("IFRS"). Although many of the changes for U.S. GAAP purposes are clarifications of existing guidance or wording changes to align with IFRS, additional disclosures about fair value measurements would be required, including (i) a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, (ii) the valuation processes used and the sensitivity of fair value measurements related to investments categorized within Level 3 of the hierarchy of fair value measurements to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any, and (iii) the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial condition but for which the fair value is required to be disclosed. The amended fair value measurement guidance will become effective for interim and annual periods beginning after December 15, 2011 and is to be applied prospectively. Early application is not permitted. The Company does not anticipate that the adoption of the amended fair value measurement guidance will have a material impact on the Company's consolidated financial statements.

Other Comprehensive Income—During June 2011, the FASB amended its guidance regarding the presentation of comprehensive income, which it states was designed to improve comparability, consistency and transparency. The amendment requires that all changes in comprehensive income be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the one-statement approach, the Company would present total net income, including its components, followed by other comprehensive income, including its components, and a total of comprehensive income. In the two-statement approach, the first statement would present total net income and its components as currently presented by the Company in its consolidated statement of operations, followed consecutively by a second statement that would present the components of other comprehensive income, total other comprehensive income and the total of comprehensive income. The amendment is to be applied retrospectively and is effective with interim and annual periods beginning after December 15, 2011, with early adoption permitted. The Company will adopt the amendment in the first quarter of 2012.

Goodwill—During September 2011, the FASB amended its guidance regarding goodwill impairment testing by allowing an entity the option to make a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of a reporting unit. The amendment became effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption was permitted. The Company adopted the amendment during the year ended December 31, 2011. The adoption of the amended guidance did not have a material impact on the Company's consolidated financial statements.

Offsetting of Assets and Liabilities—During December 2011, the FASB issued new disclosure requirements regarding the nature of an entity's rights of setoff and related arrangements associated with its derivative and other financial instruments. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods therein, with retrospective application required. The new disclosures are designed to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under IFRS. The Company does not anticipate that the adoption of the new disclosure requirements will have a material impact on the Company's consolidated financial statements.

Lazard Group Distributions—As previously described, Lazard Group's common membership interests are held by subsidiaries of Lazard Ltd and by LAZ-MD Holdings. Pursuant to provisions of the Operating Agreement, Lazard Group distributions in respect of its common membership interests are allocated to the holders of such interests on a pro rata basis. Such distributions represent amounts necessary to fund (i) any dividends Lazard Ltd may declare on its Class A common stock and (ii) tax distributions in respect of income taxes that Lazard Ltd's subsidiaries and the members of LAZ-MD Holdings incur as a result of holding Lazard Group common membership interests.

During the years ended December 31, 2011, 2010 and 2009, Lazard Group distributed the following amounts to LAZ-MD Holdings and the subsidiaries of Lazard Ltd:

	Year Ended December 31,
	2011		2010		2009
Tax distributions:

Share Repurchase Program—In January 2010, the Board of Directors of Lazard Ltd authorized, on a cumulative basis, the repurchase of up to $200,000 in aggregate cost of its Class A common stock and Lazard Group common membership interests through December 31, 2011.

Pursuant to such authorizations, purchases have been made in the open market or through privately negotiated transactions, and since inception of the program in February 2006 through December 31, 2011, purchases with respect to such program are set forth in the table below (including, during the year ended December 31, 2011, purchases of 6,135,189 Class A common shares, at an aggregate cost of $204,835, and the purchase of 19,032 Lazard Group common membership interests, at an aggregate cost of $794):

	Number  of Shares/Common Membership Interests Purchased		Average Price  Per Share/Common Membership Interest
Class A common stock		22,908,848	$	32.94
Lazard Group common membership interests		1,400,089	$	32.66

As a result of the delivery of shares of Class A common stock during the five year period ended December 31, 2011 relating to (i) the settlement of vested RSUs and deferred stock unit grants ("DSUs"), (ii) the incentive plan share awards of shares of restricted Class A common stock, (iii) the issuance of shares of restricted Class A common stock in exchange for RSUs and (iv) the delivery of shares of Class A common stock in connection with business acquisitions and the LAM Merger, there were 3,492,017 and 6,847,508 shares of Class A common stock held by our subsidiaries at December 31, 2011 and 2010, respectively. Such Class A common shares are reported, at cost, as "Class A common stock held by subsidiaries" on the accompanying consolidated statements of financial condition.

As of January 1, 2012, $212,143 of the current aggregate $375,000 share repurchase amount authorized as of such date remained available under the share repurchase program as follows – $87,143 of the $250,000 share repurchase amount expiring December 31, 2012, and all of the $125,000 share repurchase amount expiring December 31, 2013. In addition, under the terms of the 2005 Plan and the 2008 Plan, upon the vesting of RSUs, shares of Class A common stock may be withheld by the Company to cover the recipient's estimated income tax liability (see Note 16 of Notes to Consolidated Financial Statements).

Preferred Stock—Lazard Ltd has 15,000,000 authorized shares of preferred stock, par value $0.01 per share, inclusive of its Series A preferred stock and Series B preferred stock. The Series A and Series B preferred shares are each non-participating securities that are or were each convertible into Class A common stock, and have no voting or dividend rights. During the years ended December 31, 2011, 2010 and 2009, 14,100, 4,862 and 4,862 shares of Series A preferred stock, respectively, were converted into shares of Class A common stock. Such conversions resulted in the issuance of 2,434,561, 572,988, and 479,732 shares of Class A common stock in the years ended December 31, 2011, 2010 and 2009, respectively. As of December 31, 2011 and 2010, 7,921 and 22,021 shares of Series A preferred stock were outstanding, respectively, and no shares of Series B preferred stock were outstanding at such respective dates.

At December 31, 2010, 4,862 shares of the Series A preferred shares outstanding were convertible into shares of Class A common stock. During the year ended December 31, 2011, an additional 9,238 shares became convertible, with the total of 14,100 shares of Series A preferred stock converting into shares of Class A common stock during the year. The remaining 7,921 and 17,159 shares of Series A preferred stock outstanding at December 31, 2011 and 2010, respectively, may become convertible into shares of Class A common stock upon completion or satisfaction of specified obligations in the applicable acquisition agreement (see Note 9 of Notes to Consolidated Financial Statements). The Series A preferred stock conversion rate into shares of Class A common stock varies, with the ultimate conversion rate dependent on certain variables, including the value of the Class A common stock, as defined, and the currency exchange rate on the date of conversion.

Investments, at fair value	$	364,634	$	398,365
Securities sold, not yet purchased, at fair value (included in "other liabilities")	$	4,282	$	2,897

(a) At December 31, 2011, equities, interests in alternative asset management funds and fixed income funds include investments with fair values of $19,857, $2,256 and $5,212, respectively, held in order to satisfy the Company's liability upon vesting of previously granted Lazard Fund Interests and other similar deferred compensation arrangements. Lazard Fund Interests represent grants by the Company to eligible employees of actual or notional interests in several Lazard managed funds (see Note 7 and 16 of Notes to Consolidated Financial Statements).

During the year ended December 31, 2010, the Company sold "available-for-sale" debt securities for $214,540, which equaled its then carrying value, and sold "held-to-maturity" U.S. government and agency debt securities for $132,209, which had a carrying value of $126,573. Accordingly, there are no "available-for-sale" or "held-to-maturity" securities at December 31, 2010 and subsequent thereto.

During the year ended December 31, 2009, an other-than-temporary impairment charge of $1,825 pertaining to "available-for-sale" debt securities was recognized in "other-revenue" on the consolidated statement of operations, representing the credit loss component of debt securities whose fair value was below amortized cost. There were no other-than-temporary impairment charges recognized during the year ended December 31, 2010.

The Company's debt securities included in the table above are categorized as "trading" securities. Non-U.S. Government and other debt includes U.S. state and municipal debt securities, as well as amounts seeding products of our Asset Management business.

Equities primarily represent the Company's investments in marketable equity securities of large-, mid- and small-cap domestic, international and global companies seeding new Asset Management products and includes investments in public and private asset management funds managed both by LAM and third-party asset managers.  

Interests in alternative asset management funds represent (i) general partner ("GP") interests owned by Lazard in various Lazard-managed alternative asset management funds and (ii) GP interests consolidated by the Company pertaining to noncontrolling interests in such alternative asset management funds, the latter of which aggregated $777 and $8,219 at December 31, 2011 and 2010, respectively. Such noncontrolling interests, which represent GP interests held directly by certain of our Asset Management managing directors or employees of the Company, are deemed to be controlled by, and therefore consolidated by, the Company in accordance with U.S. GAAP. Noncontrolling interests are presented within "stockholders' equity" on the consolidated statements of financial condition (see Note 15 of Notes to Consolidated Financial Statements).

Fixed income funds primarily consist of amounts seeding products of our Asset Management business.

Private equity investments include those owned by Lazard and those consolidated but not owned by Lazard. Private equity investments owned by Lazard are primarily comprised of investments in private equity funds and direct private equity interests. Such investments primarily include (i) a mezzanine fund, which invests in mezzanine debt of a diversified selection of small- to mid-cap European companies, (ii) Corporate Partners II Limited ("CP II"), a private equity fund targeting significant noncontrolling-stake investments in established public and private companies, (iii) Lazard Senior Housing Partners LP ("Senior Housing"), which targets controlling interests in companies and assets in the senior housing, extended-stay hotel and shopping center sectors and (iv) Edgewater Growth Capital Partners III, L.P. ("EGCP III"), a private equity fund primarily making equity and buyout investments in lower middle market companies.

Private equity investments consolidated but not owned by Lazard relate to the economic interests that are owned by the leadership team and other investors in the Edgewater Funds ("Edgewater") which aggregated $18,502 and $67,206 at December 31, 2011 and 2010, respectively (see Note 9 of Notes to Consolidated Financial Statements).

On January 24, 2008, Sapphire Industrials Corp. ("Sapphire"), a then newly-organized special purpose acquisition company formed by the Company, completed an initial public offering (the "Sapphire IPO"). Sapphire had been included in equity method investments prior to its dissolution discussed below. Sapphire was formed for the purpose of effecting a business combination within a 24-month period (the "Business Combination") and net proceeds from the Sapphire IPO were placed in a trust account by Sapphire (the "Trust Account") pending consummation of the Business Combination. In connection with the Sapphire IPO, the Company purchased warrants from Sapphire for a total purchase price of $12,500 and Sapphire common stock for an aggregate purchase price of $50,000. The Company's investment in Sapphire had been accounted for using the equity method of accounting. On January 6, 2010, Sapphire announced it had not completed the Business Combination and it would dissolve and distribute the funds in the Trust Account to all of its public shareholders, to the extent they were holders of shares issued in the Sapphire IPO. Pursuant to such dissolution, on January 26, 2010, Sapphire made an initial distribution to the Company aggregating $50,319. All Sapphire warrants expired without value. During the fourth quarter of 2009, the Company recognized a loss of approximately $13,000 principally related to its investment in warrants of Sapphire, with such loss being recorded in "revenue-other" in the accompanying consolidated statement of operations.

The Company recognized gross investment gains and losses for the years ended December 31, 2011, 2010 and 2009, including a gain of $5,636 from the sale of "held-to-maturity" securities during the fourth quarter of 2010, in "revenue-other" on its consolidated statements of operations as follows:

	Year Ended December 31,
	2011		2010		2009
Gross investment gains	$	14,632	$	45,503	$	53,319
Gross investment losses	$	22,376	$	19,703	$	19,740

The table above includes gross unrealized investment gains and losses pertaining to "trading" securities as follows:

	Year Ended December 31,
	2011		2010		2009
Gross unrealized investment gains	$	683	$	78	$	3,723
Gross unrealized investment losses	$	1,135	$	512	$	–

Within AOCI, the Company recorded a reduction in net unrealized losses of $17,923 and $46,273 during the years ended December 31, 2010 and 2009, respectively, pertaining to "available-for-sale" debt securities. The reduction in net unrealized losses during the year ended December 31, 2010 includes the reclassification to earnings of realized gains of $1,755 and realized losses of $16,245 from the sale of the "available-for-sale" portfolio. With respect to adjustments for items reclassified to earnings, the average cost basis is utilized for purposes of calculating realized investment gains and losses.

Fair Value Measurements [Abstract]

Fair Value Measurements

6. FAIR VALUE MEASUREMENTS

Lazard categorizes its investments and certain other assets and liabilities recorded at fair value into a three-level fair value hierarchy as follows:

Level 1. Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that Lazard has the ability to access.

Level 2. Assets and liabilities whose values are based on quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in non-active markets or assets valued based on net assets value ("NAV", or its equivalent) redeemable at the measurement date or within the near term without redemption restrictions, or inputs other than quoted prices that are directly observable or derived principally from, or corroborated by, market data.

Level 3. Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management's own assumptions about the assumptions a market participant would use in pricing the asset or liability. Items included in Level 3 include securities or other financial assets whose volume and level of activity have significantly decreased when compared with normal market activity and there is no longer sufficient frequency or volume to provide pricing information on an ongoing basis as well as assets valued based on NAV not redeemable within the near term.

The Company's investments in U.S. Government and agency debt securities as well as in non-U.S. Government and other debt securities are considered Level 1 assets when their respective fair values are based on unadjusted quoted prices in active markets and are considered Level 2 assets when their fair values are primarily based on broker quotes as provided by external pricing services.

The fair value of equities is principally classified as Level 1, Level 2 or Level 3 as follows: marketable equity securities are classified as Level 1 and are valued based on the last trade price on the primary exchange for that security; public asset management funds are classified as Level 1 and are valued based on the reported closing price for the fund; investments in private asset management funds are classified as Level 2 and are primarily valued based on information provided by fund managers and, secondarily, from external pricing services to the extent managed by LAM; and Level 3 represents equities valued based on NAV and are not redeemable within the near term.

The fair value of interests in alternative asset management funds is classified as either Level 2 or Level 3 depending on the time frame of any applicable redemption restriction, and is based on information provided by external pricing services.

The Company's investments in fixed income funds are considered Level 1 assets when the fair values are based on the reported closing price for the fund or Level 2 assets when their fair values are primarily based on broker quotes as provided by external pricing services.

The fair value of private equity investments is classified as Level 3, and is primarily based on NAV and are not redeemable within the near term.

The fair values of derivatives entered into by the Company are classified as Level 2 and are based on the values of the related underlying assets, indices or reference rates as follows - the fair value of forward foreign currency exchange rate contracts is a function of the spot rate and the interest rate differential of the currency from the trade date to settlement date; the fair value of equity and fixed income swaps is based on the change in fair values of the related underlying equity security, financial instrument or index and a specified notional holding; and the fair values of interest rate swaps are based on the interest rate yield curve.

Where information reported is based on broker quotes, the Company generally obtains one quote/price per instrument. In some cases, quotes related to corporate bonds obtained through external pricing services represent the average of several broker quotes. Where information reported is based on data received from fund managers or from external pricing services, the Company reviews such information to ascertain at which level within the fair value hierarchy to classify the investment.

The following tables present the categorization of investments and certain other assets and liabilities measured at fair value on a recurring basis as of December 31, 2011 and 2010 into the three-level fair value hierarchy in accordance with fair value measurement disclosure requirements:

LAM Merger Transaction

8. LAM MERGER TRANSACTION

On September 25, 2008, the Company, LAM and LAZ Sub I, LLC, a then newly-formed subsidiary of LFNY, completed the merger of LAZ Sub I, LLC with and into LAM (the "LAM Merger"). Prior to the LAM Merger, the common equity interests of LAM were held by LFNY, and certain other equity interests of LAM, representing contingent payments should certain specified fundamental transactions occur, were held by present and former employees of LAM. Following the LAM Merger, all equity interests of LAM are owned directly or indirectly by LFNY.

The aggregate non-contingent consideration relating to the equity interests of LAM held by present and former employees of LAM and its subsidiaries (the "Transaction Consideration") consisted of (i) cash payments made from the closing of the LAM Merger through January 2, 2009 of approximately $60,000, (ii) a cash payment made on October 31, 2011 of approximately $90,000, (iii) the delivery on October 31, 2011 of 2,210,520 shares of Class A common stock and (iv) the satisfaction of certain employees' tax obligations in lieu of delivering 68,384 shares of Class A common stock on October 31, 2011. In addition, with respect to certain former employees of LAM and its subsidiaries, as of December 31, 2011, additional cash payments of $961 and additional issuances of 24,537 shares of Class A common stock are subject to delayed payment/issuance until the eighth anniversary of the closing of the LAM Merger because the applicable employees were no longer employed by Lazard or its affiliates on October 31, 2011, subject to certain exceptions. The related liabilities for the present value of the unpaid cash consideration as of December 31, 2010 were recorded in the accompanying consolidated statement of financial condition in "accrued compensation and benefits" and "other liabilities", and amounted to $15,152 and $71,394, respectively.

The accompanying Lazard Ltd condensed financial statements (the "Parent Company Financial Statements"), including the notes thereto, should be read in conjunction with the consolidated financial statements of Lazard Ltd and its subsidiaries (the "Company") and the notes thereto.

The Parent Company Financial Statements as of December 31, 2011 and 2010, and for each of the three years in the period ended December 31, 2011, are prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"), which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and the disclosures in the condensed financial statements. Management believes that the estimates utilized in the preparation of the condensed financial statements are reasonable. Actual results could differ materially from these estimates.

Many of the Company's non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. Dollar, generally the currency of the country in which such subsidiaries are domiciled. Such subsidiaries' assets and liabilities are translated into U.S. Dollars at year-end exchange rates, while revenue and expenses are translated at average exchange rates during the year based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary's functional currency to U.S. Dollars are reported in "accumulated other comprehensive income (loss), net of tax" ("AOCI"). Foreign currency remeasurement gains and losses on transactions in non-functional currencies are included on the consolidated statements of operations. Net foreign currency remeasurement gains (losses) amounted to $1,406, $(1,606) and $5,700, respectively, for the years ended December 31, 2011, 2010 and 2009, and are included in "revenue-other" on the respective consolidated statements of operations.

Use Of Estimates

Use of Estimates—In preparing the consolidated financial statements, management makes estimates and assumptions regarding:

• valuations of assets and liabilities requiring fair value estimates including, but not limited to, investments, derivatives, securities sold, not yet purchased and assumptions used to value pension and other post-retirement plans;

• the adequacy of the allowance for doubtful accounts;

• the realization of deferred taxes and adequacy of tax reserves for uncertain tax positions;

• the outcome of litigation;

• the carrying amount of goodwill and other intangible assets;

• the amortization period of intangible assets;

• the valuation of shares issued or issuable that contain transfer restrictions;

• share-based and other deferred compensation plan forfeitures, and;

• other matters that affect the reported amounts and disclosure of contingencies in the consolidated financial statements.

Estimates, by their nature, are based on judgment and available information. Therefore, actual results could differ from those estimates and could have a material impact on the consolidated financial statements.

Cash And Cash Equivalents

Cash and Cash Equivalents—The Company defines cash equivalents as short-term, highly liquid securities and cash deposits with original maturities of 90 days or less when purchased.

Deposits With Banks

Deposits with Banks—Represents LFB's short-term deposits, principally with the Banque de France. The level of these deposits may be driven by the level of LFB customer and bank-related interest-bearing time and demand deposits (which can fluctuate significantly on a daily basis) and by changes in asset allocation.

Cash Deposited With Clearing Organizations And Other Segregated Cash

Cash Deposited with Clearing Organizations and Other Segregated Cash—Primarily represents restricted cash deposits made by the Company, including those to satisfy the requirements of clearing organizations.

Allowance For Doubtful Accounts

Allowance for Doubtful Accounts—We maintain an allowance for bad debts to provide for estimated losses relating to fees and customer receivables. We determine the adequacy of the allowance by estimating the probability of loss based on management's analysis of the client's creditworthiness and specifically reserve against exposures where we determine the receivables may be impaired, which may include situations where a fee is in dispute or litigation has commenced.

With respect to fees receivable from Financial Advisory activities, such receivables are generally deemed past due when they are outstanding 60 days from the date of invoice. However, some Financial Advisory transactions include specific contractual payment terms that may vary from one month to four years (as is the case for our Private Fund Advisory fees) following the invoice date or may be subject to court approval (as is the case with bankruptcy-related restructuring assignments). In such cases, receivables are deemed past due when payment is not received by the agreed-upon contractual date or the court approval date, respectively. Financial Advisory fee receivables past due in excess of 180 days are fully provided for unless there is evidence that the balance is collectable. Asset Management fees are deemed past due and fully provided for when such receivables are outstanding 12 months after the invoice date. Notwithstanding our policy for receivables past due, we specifically reserve against exposures relating to Financial Advisory and Asset Management fees where we determine receivables are impaired.

See Note 4 of Notes to Consolidated Financial Statements for additional information regarding receivables.

Investments

Investments—Investments in debt and marketable equity securities held either directly or indirectly through asset management funds at the Company's broker-dealer subsidiaries are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard industry practices. Such amounts are reflected in "revenue-other" in the consolidated statements of operations.

Investments in debt and marketable equity securities held at the Company's non broker-dealer subsidiaries may include "trading", "available-for-sale" and "held-to-maturity" securities. Investments in debt and marketable equity securities considered "trading" securities are accounted for at fair value, with any increase or decrease in fair value reflected in "revenue-other" in the consolidated statements of operations. Investments in debt securities considered "available-for-sale" securities are accounted for at fair value, with any increase or decrease in fair value reported in AOCI, until such time they are realized and reclassified to earnings. Investments in debt securities considered "held-to-maturity" securities are accounted for at amortized cost. Declines in the fair value of "available-for-sale" and "held-to-maturity" securities that are determined to be other-than-temporary are charged to earnings, which, for periods beginning after April 1, 2009, may only include the credit loss component of such declines. At December 31, 2010 and subsequent thereto, the Company had no "available-for-sale" or "held-to-maturity" debt or marketable equity securities.

Other investments include general partnership and limited partnership interests in alternative asset management funds, fixed income funds and private equity investments accounted for at fair value, as well as investments accounted for under the equity method of accounting. Any increases or decreases in the carrying value of those investments accounted for at fair value and the Company's share of net income or losses pertaining to its equity method investments are reflected in "revenue-other" in the consolidated statements of operations.

Dividend income is reflected in "revenue-other" on the consolidated statements of operations. Interest income includes accretion or amortization of any discount or premium arising at acquisition of the related debt security. Securities transactions and the related revenue and expenses are recorded on a "trade date" basis.

See Notes 5 and 6 of Notes to Consolidated Financial Statements for additional information regarding the Company's investments.

Property-Net

Property-net—Property is stated at cost or, in the case of buildings under capital leases, the present value of the future minimum lease payments, less accumulated depreciation and amortization. Buildings represent owned property and amounts recorded pursuant to capital leases (see Notes 10 and 14 of Notes to Consolidated Financial Statements), with the related obligations recorded as capital lease obligations. Such buildings are depreciated on a straight-line basis over their estimated useful lives. Leasehold improvements are capitalized and are amortized over the lesser of the economic useful life of the improvement or the term of the lease. Depreciation of furniture and equipment, including computer hardware and software, is determined on a straight-line basis using estimated useful lives. Depreciation and amortization expense aggregating $24,580, $22,712 and $22,541 for the years ended December 31, 2011, 2010 and 2009, respectively, is included on the respective consolidated statements of operations in "occupancy and equipment" or "technology and information services", depending on the nature of the underlying asset. Repairs and maintenance are expensed as incurred.

Goodwill And Other Intangible Assets

Goodwill and Other Intangible Assets—As goodwill has an indefinite life, it is required to be tested for impairment annually or more frequently if circumstances indicate impairment may have occurred. For years prior to 2011, the Company assessed whether any goodwill recorded by its applicable reporting units was impaired by comparing the fair value of each reporting unit with its respective carrying amount. In this process, Lazard used its best judgment and information available to it at the time to perform this review and utilized various valuation techniques in order to determine the applicable fair values. Commencing in 2011, as permitted under an amendment issued by the Financial Accounting Standards Board (the "FASB"), the Company elected to perform a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of the reporting unit.

Intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. This analysis is performed by comparing the carrying value of the intangible asset being reviewed for impairment to the current and expected future cash flows expected to be generated from such asset on an undiscounted basis, including eventual disposition. An impairment loss would be measured for the amount by which the carrying amount of the intangible asset exceeds its fair value.

See Note 11 of Notes to Consolidated Financial Statements with respect to goodwill and other intangible assets.

Derivative Instruments

Derivative Instruments—A derivative is typically defined as an instrument whose value is "derived" from underlying assets, indices or reference rates, such as a future, forward, swap, or option contract, or other financial instrument with similar characteristics. Derivative contracts often involve future commitments to exchange interest payment streams or currencies based on a notional or contractual amount (e.g., interest rate swaps or currency forwards) or to purchase or sell other financial instruments at specified terms on a specified date (e.g., options to buy or sell securities or currencies).

The Company enters into forward foreign currency exchange rate contracts, interest rate swaps, interest rate futures, equity and fixed income swaps and other derivative contracts to hedge exposures to fluctuations in currency exchange rates, interest rates and equity and debt markets. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company's derivative instruments are recorded at their fair value, and are included in "other assets" and "other liabilities" on the consolidated statements of financial condition. Except for derivative instruments hedging its then "available-for-sale" securities held prior to 2011 (see Note 5 of Notes to Consolidated Financial Statements), the Company elected not to apply hedge accounting to its other derivative instruments. Gains and losses on the Company's derivative contracts not designated as hedging instruments, as well as gains and losses on derivative instruments accounted for as fair value hedges, are included in "interest income" and "interest expense", respectively, or "revenue-other", depending on the nature of the underlying item, on the consolidated statements of operations. Furthermore, with respect to derivative instruments designated as fair value hedges, the hedged item is required to be adjusted for changes in fair value of the risk being hedged, with such adjustment accounted for in the consolidated statements of operations.

In addition to the derivative instruments above, the Company recognized a derivative liability relating to its obligation pertaining to Lazard Fund Interests awards ("Lazard Fund Interests") and other similar deferred compensation arrangements, the fair value of which is based on the value of the underlying investments and is included in "accrued compensation and benefits" on the consolidated statement of financial condition as of December 31, 2011. Changes in the fair value of the derivative liability are included in "compensation and benefits" on the consolidated statement of operations for the year ended December 31, 2011, the impact of which equally offsets the changes in the fair value of the underlying investments owned and is reported in "revenue-other" in the consolidated statement of operations.  For information regarding Lazard Fund Interests and other similar deferred compensation arrangements, see Notes 7 and 16 of Notes to Consolidated Financial statments.

Deposits And Other Customer Payables

Deposits and Other Customer Payables—Principally relates to LFB customer-related demand and time deposits, both  interest-bearing and non-interest bearing, short-term inter-bank borrowings and amounts due on short-term collateralized borrowing activities. Collateralized borrowing activities amounted to $8,928 and $7,483 at December 31, 2011 and 2010, respectively, and were fully collateralized with pledged assets of equal or greater value at each such date.

Securities Sold, Not Yet Purchased

Securities Sold, Not Yet Purchased—Securities sold, not yet purchased represents liabilities for securities sold for which payment has been received and the obligations to deliver such securities are included within "other liabilities" in the consolidated statements of financial condition. These securities are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard securities industry practices. Such gains and losses are reflected in "revenue-other" in the consolidated statements of operations.

Fair Value Of Financial Assets And Liabilities

Fair Value of Financial Assets and Liabilities—The majority of the Company's financial assets and liabilities are recorded at fair value or at amounts that approximate fair value. Such assets and liabilities include cash and cash equivalents, deposits with banks, cash deposited with clearing organizations and other segregated cash, receivables, investments (excluding investments accounted for at amortized cost, interest-bearing deposits or using the equity method of accounting), derivative instruments and deposits and other customer payables. For information regarding the fair value of the Company's senior and subordinated debt, see Note 13 of Notes to Consolidated Financial Statements.

Revenue Recognition

Revenue Recognition

Investment Banking and Other Advisory Fees—Fees for M&A and Strategic Advisory services and Restructuring advisory services are recorded when earned, which is generally the date the related transactions are consummated. Expenses that are directly related to such transactions and billable to clients are deferred to match revenue recognition. "Investment banking and other advisory fees" on the Company's consolidated statements of operations are presented net of client reimbursements of expenses. The amount of expenses reimbursed by clients for the years ended December 31, 2011, 2010 and 2009 are $18,942, $20,216 and $21,673, respectively.

Money Management and Incentive Fees—Money management fees are derived from fees for investment management and advisory services provided to institutional and private clients. Revenue is recorded on an accrual basis primarily based on a percentage of client assets managed. Fees vary with the type of assets managed, with higher fees earned on equity assets, alternative investment (such as hedge funds) and private equity products, and lower fees earned on fixed income and money market products.

The Company may earn performance-based incentive fees on various investment products, including alternative investment funds such as hedge funds, private equity funds and traditional investment strategies. Incentive fees are calculated based on a specified percentage of a fund's net appreciation, in some cases in excess of established benchmarks. Incentive fees on private equity funds also may be earned in the form of a carried interest if profits from investments exceed a specified threshold. These incentive fees are recorded when realized and are paid at the end of the measurement period. Incentive fees on hedge funds generally are subject to loss carry-forward provisions in which losses incurred by the funds in any year are applied against certain future period net appreciation before any incentive fees can be earned.

The Company records incentive fees at the end of the relevant performance measurement period, when potential uncertainties regarding the ultimate realizable amounts have been determined. The performance fee measurement period is generally an annual period, unless an account terminates during the year. These incentive fees received at the end of the measurement period are not subject to reversal or payback.

Receivables relating to money management and incentive fees are reported in "fees receivable" on the consolidated statements of financial condition.

Soft Dollar Arrangements— The Company's Asset Management business obtains research and other services through "soft dollar" arrangements. Consistent with the "soft dollar" safe harbor established by Section 28(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Asset Management business does not have any contractual obligation or arrangement requiring it to pay for research and other services obtained through soft dollar arrangements with brokers. Instead, the provider is obligated to pay for the services. Consequently, the Company does not incur any liability and does not accrue any expenses in connection with any research or other services obtained by the Asset Management business pursuant to such soft dollar arrangements. If the use of soft dollars is limited or prohibited in the future by regulation, we may have to bear the costs of such research and other services.

Share-Based Incentive Compensation Awards

Share-Based Incentive Compensation Awards—Share-based incentive compensation awards that do not require future service are expensed immediately; however, awards that require future service are amortized over the applicable vesting period or requisite service period. Expense relating to share-based incentive compensation awards is generally based on the fair value of the Company's Class A common stock on the date of grant, and is recognized in "compensation and benefits" (and, as applicable, in "restructuring" expense, with respect to the expense associated with the acceleration of unrecognized expense pertaining to awards granted previously to individuals who were terminated by the Company in the restructuring programs described in Note 18 of Notes to Consolidated Financial Statements).

Income Taxes

Income Taxes—Lazard Ltd, through certain of its subsidiaries, is subject to U.S. corporate federal income tax on its allocable share of the results of operations of Lazard Group, and certain non-U.S. subsidiaries of the Company are subject to income taxes in their local jurisdictions. In addition, the Company is subject to New York City Unincorporated Business Taxes ("UBT") attributable to Lazard Group's operations apportioned to New York City.

Substantially all of Lazard's operations outside the U.S. are conducted in "pass-through" entities for U.S. income tax purposes and the Company provides for U.S. income taxes on a current basis for substantially all of those earnings. The repatriation of prior year earnings attributable to "non-pass-through" entities would not result in the recognition of a material amount of additional U.S. income taxes.

Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. Such temporary differences are reflected as deferred tax assets and liabilities and are included in "other assets" and "other liabilities", respectively, on the consolidated statements of financial condition.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized and, when necessary, a valuation allowance is established. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. Management considers the following possible sources of taxable income when assessing the realization of deferred tax assets:

• future reversals of existing taxable temporary differences;

• future taxable income exclusive of reversing temporary differences and carryforwards;

• taxable income in prior carryback years; and

• tax-planning strategies.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence, including, but not limited to, the following:

• nature, frequency, and severity of any recent losses;

• duration of statutory carryforward periods;

• historical experience with tax attributes expiring unused; and

• near- and medium-term financial outlook.

Furthermore, management applies the "more likely than not" criteria prior to the recognition of a financial statement benefit of a tax position taken or expected to be taken in a tax return with respect to uncertainty in income taxes.

The Company recognizes interest and/or penalties related to income tax matters in "income tax expense". See Note 19 of Notes to Consolidated Financial Statements for additional information relating to income taxes.

Senior And Subordinated Debt [Abstract]

Senior And Subordinated Debt

13. SENIOR AND SUBORDINATED DEBT

Senior Debt—Senior debt is comprised of the following as of December 31, 2011 and 2010:

	Initial Principal Amount		Maturity Date		Annual Interest Rate			Outstanding As Of December 31,
								2011		2010
Lazard Group 7.125% Senior Notes (a)	$	550,000		5/15/15		7.125	%	$	528,500	$	528,500
Lazard Group 6.85% Senior Notes (b)		600,000		6/15/17		6.85	%		548,350		548,350
Lazard Group Credit Facility (c)		150,000		4/29/13		1.90	%		–		–
Total								$	1,076,850	$	1,076,850

(a) During the year ended December 31, 2010, the Company repurchased $10,000 principal amount of the 7.125% Senior Notes, at a cost, excluding accrued interest, of $10,375, and, after the write-off of applicable unamortized debt issuance costs of $49, the Company recognized a pre-tax loss of $424. In connection with the issuance of the 7.125% Senior Notes, on April 1, 2005, Lazard Group entered into an interest rate forward agreement. On May 9, 2005, Lazard Group settled the interest rate forward agreement, of which $11,003 was deemed to be the effective portion of the hedge and recorded within AOCI and is being amortized as a charge to interest expense over the ten-year term of the 7.125% Senior Notes.

(b) During the year ended December 31, 2009, the Company repurchased $900 principal amount of the 6.85% Senior Notes, at a cost, excluding accrued interest, of $635, and, after the write-off of applicable unamortized debt issuance costs of $7, the Company recognized a pre-tax gain of $258.

(c) On April 29, 2010, Lazard Group entered into a $150,000, three-year senior revolving credit facility with a group of lenders (the "Credit Facility"). The Credit Facility, as amended, replaced the prior revolving credit facility, which was terminated as a condition to effectiveness of the Credit Facility. Interest rates under the Credit Facility vary and are based on either a Federal Funds rate or a Eurodollar rate, in each case plus an applicable margin. As of December 31, 2011, the annual interest rate for a loan accruing interest (based on the Federal Funds overnight rate), including the applicable margin, was 1.90%. At December 31, 2011 and 2010, no amounts were outstanding under the Credit Facility.

The Credit Facility contains customary terms and conditions, including certain financial covenants. In addition, the Credit Facility, the indenture and the supplemental indentures relating to Lazard Group's senior notes, contain certain covenants, events of default and other customary provisions, including a customary make-whole provision in the event of early redemption where applicable. As of December 31, 2011, the Company was in compliance with all of these provisions. All of the Company's senior debt obligations are unsecured.

As of December 31, 2011, the Company had approximately $312,000 in unused lines of credit available to it, including the Credit Facility, and unused lines of credit available to LFB of approximately $91,000 (at December 31, 2011 exchange rates) and Edgewater of $65,000. In addition, LFB has access to the Eurosystem Covered Bond Purchase Program of the Banque de France.

Subordinated Debt—Subordinated debt at December 31, 2010 represented a promissory note amounting to $150,000. The note had a maturity date of September 30, 2016 and had a fixed interest rate of 3.25% per annum. Until June 30, 2011, the note had a conversion feature which permitted the holder to convert the note into a maximum of 2,631,570 shares of Class A common stock at an effective conversion price of $57 per share. No conversions had occurred. On July 22, 2011, the Company repurchased the note, at a cost, excluding accrued interest, of $131,829. Such repurchase resulted in a pre-tax gain of $18,171, which was recognized by the Company in the third quarter of 2011 and included in "revenue-other" on the accompanying consolidated statement of operations.

Debt maturities relating to senior borrowings outstanding at December 31, 2011 for each of the five years in the period ending December 31, 2016, and thereafter, are set forth in the table below.

Year Ending December 31,
2012-2014	$	–
2015		528,500
2016		–
Thereafter		548,350
Total	$	1,076,850

The Company's debt at December 31, 2011 and 2010 is recorded at historical amounts. At December 31, 2011 and 2010, the fair value of the Company's senior and subordinated debt outstanding was approximately $1,138,000 and $1,271,000, respectively, and exceeded the aggregate carrying value by approximately $61,000 and $44,000, respectively. The fair value of the Company's senior and subordinated debt was estimated using a discounted cash flow analysis based on the Company's current borrowing rates for similar types of borrowing arrangements or based on market quotations, where available.

Restructuring Plans [Abstract]

Restructuring Plans

18. RESTRUCTURING PLAN S

In each of the first quarters of 2010 and 2009, the Company announced a restructuring plan which included certain staff reductions and realignments of personnel (the "2010 Restructuring Plan" and the "2009 Restructuring Plan", respectively, and collectively the "2010 and 2009 Restructuring Plans"). In connection with the 2010 Restructuring Plan, the Company recorded a charge in the first quarter of 2010 of $87,108, inclusive of $46,880 relating to the acceleration of RSUs (in aggregate, the "2010 Restructuring Charge"), and, in connection with the 2009 Restructuring Plan, the Company recorded a charge in the first quarter of 2009 of $62,550, inclusive of $24,239 relating to the acceleration of RSUs (in aggregate, the "2009 Restructuring Charge", and, together with the 2010 Restructuring Charge, the "2010 and 2009 Restructuring Charges").

The 2010 and 2009 Restructuring Charges primarily consisted of compensation-related expenses, including the acceleration of unrecognized expenses pertaining to RSUs previously granted to individuals who were terminated pursuant to the restructuring, severance and benefit payments and other costs. As of December 31, 2011 and 2010, the remaining liability associated with the 2010 Restructuring Plan was $9,456 and $21,381, respectively, and, as of December 31, 2011 and 2010, the remaining liability associated with the 2009 Restructuring Plan was $2,791 and $5,427, respectively. During the years ended December 31, 2011 and 2010, the Company made cash payments of $10,625 and $18,847, respectively, for the 2010 Restructuring Plan and $1,436 and $6,073, respectively, for the 2009 Restructuring Plan. Further during the year ended December 31, 2011, we reduced our provisions by $1,300 and $1,200 for the 2010 and 2009 Restructuring Plans, respectively. Liabilities relating to the 2010 and 2009 Restructuring Plans are reported within "accrued compensation and benefits" and "other liabilities" on the accompanying consolidated statements of financial condition.

(a) During the year ended December 31, 2010, the Company repurchased $10,000 principal amount of the 7.125% Senior Notes, at a cost, excluding accrued interest, of $10,375, and, after the write-off of applicable unamortized debt issuance costs of $49, the Company recognized a pre-tax loss of $424. In connection with the issuance of the 7.125% Senior Notes, on April 1, 2005, Lazard Group entered into an interest rate forward agreement. On May 9, 2005, Lazard Group settled the interest rate forward agreement, of which $11,003 was deemed to be the effective portion of the hedge and recorded within AOCI and is being amortized as a charge to interest expense over the ten-year term of the 7.125% Senior Notes.

(b) During the year ended December 31, 2009, the Company repurchased $900 principal amount of the 6.85% Senior Notes, at a cost, excluding accrued interest, of $635, and, after the write-off of applicable unamortized debt issuance costs of $7, the Company recognized a pre-tax gain of $258.

(c) On April 29, 2010, Lazard Group entered into a $150,000, three-year senior revolving credit facility with a group of lenders (the "Credit Facility"). The Credit Facility, as amended, replaced the prior revolving credit facility, which was terminated as a condition to effectiveness of the Credit Facility. Interest rates under the Credit Facility vary and are based on either a Federal Funds rate or a Eurodollar rate, in each case plus an applicable margin. As of December 31, 2011, the annual interest rate for a loan accruing interest (based on the Federal Funds overnight rate), including the applicable margin, was 1.90%. At December 31, 2011 and 2010, no amounts were outstanding under the Credit Facility.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

2. SIGNIFICANT ACCOUNTING POLICIES

The accounting policies below relate to reported amounts and disclosures in the consolidated financial statements.

Foreign Currency Translation—The consolidated financial statements are presented in U.S. Dollars. Many of the Company's non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. Dollar, generally the currency of the country in which such subsidiaries are domiciled. Such subsidiaries' assets and liabilities are translated into U.S. Dollars at year-end exchange rates, while revenue and expenses are translated at average exchange rates during the year based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary's functional currency to U.S. Dollars are reported in "accumulated other comprehensive income (loss), net of tax" ("AOCI"). Foreign currency remeasurement gains and losses on transactions in non-functional currencies are included on the consolidated statements of operations. Net foreign currency remeasurement gains (losses) amounted to $1,406, $(1,606) and $5,700, respectively, for the years ended December 31, 2011, 2010 and 2009, and are included in "revenue-other" on the respective consolidated statements of operations.

Use of Estimates—In preparing the consolidated financial statements, management makes estimates and assumptions regarding:

• valuations of assets and liabilities requiring fair value estimates including, but not limited to, investments, derivatives, securities sold, not yet purchased and assumptions used to value pension and other post-retirement plans;

• the adequacy of the allowance for doubtful accounts;

• the realization of deferred taxes and adequacy of tax reserves for uncertain tax positions;

• the outcome of litigation;

• the carrying amount of goodwill and other intangible assets;

• the amortization period of intangible assets;

• the valuation of shares issued or issuable that contain transfer restrictions;

• share-based and other deferred compensation plan forfeitures, and;

• other matters that affect the reported amounts and disclosure of contingencies in the consolidated financial statements.

Estimates, by their nature, are based on judgment and available information. Therefore, actual results could differ from those estimates and could have a material impact on the consolidated financial statements.

Cash and Cash Equivalents—The Company defines cash equivalents as short-term, highly liquid securities and cash deposits with original maturities of 90 days or less when purchased.

Deposits with Banks—Represents LFB's short-term deposits, principally with the Banque de France. The level of these deposits may be driven by the level of LFB customer and bank-related interest-bearing time and demand deposits (which can fluctuate significantly on a daily basis) and by changes in asset allocation.

Cash Deposited with Clearing Organizations and Other Segregated Cash—Primarily represents restricted cash deposits made by the Company, including those to satisfy the requirements of clearing organizations.

Allowance for Doubtful Accounts—We maintain an allowance for bad debts to provide for estimated losses relating to fees and customer receivables. We determine the adequacy of the allowance by estimating the probability of loss based on management's analysis of the client's creditworthiness and specifically reserve against exposures where we determine the receivables may be impaired, which may include situations where a fee is in dispute or litigation has commenced.

With respect to fees receivable from Financial Advisory activities, such receivables are generally deemed past due when they are outstanding 60 days from the date of invoice. However, some Financial Advisory transactions include specific contractual payment terms that may vary from one month to four years (as is the case for our Private Fund Advisory fees) following the invoice date or may be subject to court approval (as is the case with bankruptcy-related restructuring assignments). In such cases, receivables are deemed past due when payment is not received by the agreed-upon contractual date or the court approval date, respectively. Financial Advisory fee receivables past due in excess of 180 days are fully provided for unless there is evidence that the balance is collectable. Asset Management fees are deemed past due and fully provided for when such receivables are outstanding 12 months after the invoice date. Notwithstanding our policy for receivables past due, we specifically reserve against exposures relating to Financial Advisory and Asset Management fees where we determine receivables are impaired.

See Note 4 of Notes to Consolidated Financial Statements for additional information regarding receivables.

Investments—Investments in debt and marketable equity securities held either directly or indirectly through asset management funds at the Company's broker-dealer subsidiaries are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard industry practices. Such amounts are reflected in "revenue-other" in the consolidated statements of operations.

Investments in debt and marketable equity securities held at the Company's non broker-dealer subsidiaries may include "trading", "available-for-sale" and "held-to-maturity" securities. Investments in debt and marketable equity securities considered "trading" securities are accounted for at fair value, with any increase or decrease in fair value reflected in "revenue-other" in the consolidated statements of operations. Investments in debt securities considered "available-for-sale" securities are accounted for at fair value, with any increase or decrease in fair value reported in AOCI, until such time they are realized and reclassified to earnings. Investments in debt securities considered "held-to-maturity" securities are accounted for at amortized cost. Declines in the fair value of "available-for-sale" and "held-to-maturity" securities that are determined to be other-than-temporary are charged to earnings, which, for periods beginning after April 1, 2009, may only include the credit loss component of such declines. At December 31, 2010 and subsequent thereto, the Company had no "available-for-sale" or "held-to-maturity" debt or marketable equity securities.

Other investments include general partnership and limited partnership interests in alternative asset management funds, fixed income funds and private equity investments accounted for at fair value, as well as investments accounted for under the equity method of accounting. Any increases or decreases in the carrying value of those investments accounted for at fair value and the Company's share of net income or losses pertaining to its equity method investments are reflected in "revenue-other" in the consolidated statements of operations.

Dividend income is reflected in "revenue-other" on the consolidated statements of operations. Interest income includes accretion or amortization of any discount or premium arising at acquisition of the related debt security. Securities transactions and the related revenue and expenses are recorded on a "trade date" basis.

See Notes 5 and 6 of Notes to Consolidated Financial Statements for additional information regarding the Company's investments.

Property-net—Property is stated at cost or, in the case of buildings under capital leases, the present value of the future minimum lease payments, less accumulated depreciation and amortization. Buildings represent owned property and amounts recorded pursuant to capital leases (see Notes 10 and 14 of Notes to Consolidated Financial Statements), with the related obligations recorded as capital lease obligations. Such buildings are depreciated on a straight-line basis over their estimated useful lives. Leasehold improvements are capitalized and are amortized over the lesser of the economic useful life of the improvement or the term of the lease. Depreciation of furniture and equipment, including computer hardware and software, is determined on a straight-line basis using estimated useful lives. Depreciation and amortization expense aggregating $24,580, $22,712 and $22,541 for the years ended December 31, 2011, 2010 and 2009, respectively, is included on the respective consolidated statements of operations in "occupancy and equipment" or "technology and information services", depending on the nature of the underlying asset. Repairs and maintenance are expensed as incurred.

Goodwill and Other Intangible Assets—As goodwill has an indefinite life, it is required to be tested for impairment annually or more frequently if circumstances indicate impairment may have occurred. For years prior to 2011, the Company assessed whether any goodwill recorded by its applicable reporting units was impaired by comparing the fair value of each reporting unit with its respective carrying amount. In this process, Lazard used its best judgment and information available to it at the time to perform this review and utilized various valuation techniques in order to determine the applicable fair values. Commencing in 2011, as permitted under an amendment issued by the Financial Accounting Standards Board (the "FASB"), the Company elected to perform a qualitative evaluation about whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount in lieu of actually calculating the fair value of the reporting unit.

Intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. This analysis is performed by comparing the carrying value of the intangible asset being reviewed for impairment to the current and expected future cash flows expected to be generated from such asset on an undiscounted basis, including eventual disposition. An impairment loss would be measured for the amount by which the carrying amount of the intangible asset exceeds its fair value.

See Note 11 of Notes to Consolidated Financial Statements with respect to goodwill and other intangible assets.

Derivative Instruments—A derivative is typically defined as an instrument whose value is "derived" from underlying assets, indices or reference rates, such as a future, forward, swap, or option contract, or other financial instrument with similar characteristics. Derivative contracts often involve future commitments to exchange interest payment streams or currencies based on a notional or contractual amount (e.g., interest rate swaps or currency forwards) or to purchase or sell other financial instruments at specified terms on a specified date (e.g., options to buy or sell securities or currencies).

The Company enters into forward foreign currency exchange rate contracts, interest rate swaps, interest rate futures, equity and fixed income swaps and other derivative contracts to hedge exposures to fluctuations in currency exchange rates, interest rates and equity and debt markets. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company's derivative instruments are recorded at their fair value, and are included in "other assets" and "other liabilities" on the consolidated statements of financial condition. Except for derivative instruments hedging its then "available-for-sale" securities held prior to 2011 (see Note 5 of Notes to Consolidated Financial Statements), the Company elected not to apply hedge accounting to its other derivative instruments. Gains and losses on the Company's derivative contracts not designated as hedging instruments, as well as gains and losses on derivative instruments accounted for as fair value hedges, are included in "interest income" and "interest expense", respectively, or "revenue-other", depending on the nature of the underlying item, on the consolidated statements of operations. Furthermore, with respect to derivative instruments designated as fair value hedges, the hedged item is required to be adjusted for changes in fair value of the risk being hedged, with such adjustment accounted for in the consolidated statements of operations.

In addition to the derivative instruments above, the Company recognized a derivative liability relating to its obligation pertaining to Lazard Fund Interests awards ("Lazard Fund Interests") and other similar deferred compensation arrangements, the fair value of which is based on the value of the underlying investments and is included in "accrued compensation and benefits" on the consolidated statement of financial condition as of December 31, 2011. Changes in the fair value of the derivative liability are included in "compensation and benefits" on the consolidated statement of operations for the year ended December 31, 2011, the impact of which equally offsets the changes in the fair value of the underlying investments owned and is reported in "revenue-other" in the consolidated statement of operations.  For information regarding Lazard Fund Interests and other similar deferred compensation arrangements, see Notes 7 and 16 of Notes to Consolidated Financial statments.

Deposits and Other Customer Payables—Principally relates to LFB customer-related demand and time deposits, both  interest-bearing and non-interest bearing, short-term inter-bank borrowings and amounts due on short-term collateralized borrowing activities. Collateralized borrowing activities amounted to $8,928 and $7,483 at December 31, 2011 and 2010, respectively, and were fully collateralized with pledged assets of equal or greater value at each such date.

Securities Sold, Not Yet Purchased—Securities sold, not yet purchased represents liabilities for securities sold for which payment has been received and the obligations to deliver such securities are included within "other liabilities" in the consolidated statements of financial condition. These securities are accounted for at fair value, with any increase or decrease in fair value recorded in earnings in accordance with standard securities industry practices. Such gains and losses are reflected in "revenue-other" in the consolidated statements of operations.

Fair Value of Financial Assets and Liabilities—The majority of the Company's financial assets and liabilities are recorded at fair value or at amounts that approximate fair value. Such assets and liabilities include cash and cash equivalents, deposits with banks, cash deposited with clearing organizations and other segregated cash, receivables, investments (excluding investments accounted for at amortized cost, interest-bearing deposits or using the equity method of accounting), derivative instruments and deposits and other customer payables. For information regarding the fair value of the Company's senior and subordinated debt, see Note 13 of Notes to Consolidated Financial Statements.

Revenue Recognition

Investment Banking and Other Advisory Fees—Fees for M&A and Strategic Advisory services and Restructuring advisory services are recorded when earned, which is generally the date the related transactions are consummated. Expenses that are directly related to such transactions and billable to clients are deferred to match revenue recognition. "Investment banking and other advisory fees" on the Company's consolidated statements of operations are presented net of client reimbursements of expenses. The amount of expenses reimbursed by clients for the years ended December 31, 2011, 2010 and 2009 are $18,942, $20,216 and $21,673, respectively.

Money Management and Incentive Fees—Money management fees are derived from fees for investment management and advisory services provided to institutional and private clients. Revenue is recorded on an accrual basis primarily based on a percentage of client assets managed. Fees vary with the type of assets managed, with higher fees earned on equity assets, alternative investment (such as hedge funds) and private equity products, and lower fees earned on fixed income and money market products.

The Company may earn performance-based incentive fees on various investment products, including alternative investment funds such as hedge funds, private equity funds and traditional investment strategies. Incentive fees are calculated based on a specified percentage of a fund's net appreciation, in some cases in excess of established benchmarks. Incentive fees on private equity funds also may be earned in the form of a carried interest if profits from investments exceed a specified threshold. These incentive fees are recorded when realized and are paid at the end of the measurement period. Incentive fees on hedge funds generally are subject to loss carry-forward provisions in which losses incurred by the funds in any year are applied against certain future period net appreciation before any incentive fees can be earned.

The Company records incentive fees at the end of the relevant performance measurement period, when potential uncertainties regarding the ultimate realizable amounts have been determined. The performance fee measurement period is generally an annual period, unless an account terminates during the year. These incentive fees received at the end of the measurement period are not subject to reversal or payback.

Receivables relating to money management and incentive fees are reported in "fees receivable" on the consolidated statements of financial condition.

Soft Dollar Arrangements— The Company's Asset Management business obtains research and other services through "soft dollar" arrangements. Consistent with the "soft dollar" safe harbor established by Section 28(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Asset Management business does not have any contractual obligation or arrangement requiring it to pay for research and other services obtained through soft dollar arrangements with brokers. Instead, the provider is obligated to pay for the services. Consequently, the Company does not incur any liability and does not accrue any expenses in connection with any research or other services obtained by the Asset Management business pursuant to such soft dollar arrangements. If the use of soft dollars is limited or prohibited in the future by regulation, we may have to bear the costs of such research and other services.

Share-Based Incentive Compensation Awards—Share-based incentive compensation awards that do not require future service are expensed immediately; however, awards that require future service are amortized over the applicable vesting period or requisite service period. Expense relating to share-based incentive compensation awards is generally based on the fair value of the Company's Class A common stock on the date of grant, and is recognized in "compensation and benefits" (and, as applicable, in "restructuring" expense, with respect to the expense associated with the acceleration of unrecognized expense pertaining to awards granted previously to individuals who were terminated by the Company in the restructuring programs described in Note 18 of Notes to Consolidated Financial Statements).

Income Taxes—Lazard Ltd, through certain of its subsidiaries, is subject to U.S. corporate federal income tax on its allocable share of the results of operations of Lazard Group, and certain non-U.S. subsidiaries of the Company are subject to income taxes in their local jurisdictions. In addition, the Company is subject to New York City Unincorporated Business Taxes ("UBT") attributable to Lazard Group's operations apportioned to New York City.

Substantially all of Lazard's operations outside the U.S. are conducted in "pass-through" entities for U.S. income tax purposes and the Company provides for U.S. income taxes on a current basis for substantially all of those earnings. The repatriation of prior year earnings attributable to "non-pass-through" entities would not result in the recognition of a material amount of additional U.S. income taxes.

Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. Such temporary differences are reflected as deferred tax assets and liabilities and are included in "other assets" and "other liabilities", respectively, on the consolidated statements of financial condition.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized and, when necessary, a valuation allowance is established. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. Management considers the following possible sources of taxable income when assessing the realization of deferred tax assets:

• future reversals of existing taxable temporary differences;

• future taxable income exclusive of reversing temporary differences and carryforwards;

• taxable income in prior carryback years; and

• tax-planning strategies.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence, including, but not limited to, the following:

• nature, frequency, and severity of any recent losses;

• duration of statutory carryforward periods;

• historical experience with tax attributes expiring unused; and

• near- and medium-term financial outlook.

Furthermore, management applies the "more likely than not" criteria prior to the recognition of a financial statement benefit of a tax position taken or expected to be taken in a tax return with respect to uncertainty in income taxes.

The Company recognizes interest and/or penalties related to income tax matters in "income tax expense". See Note 19 of Notes to Consolidated Financial Statements for additional information relating to income taxes.

Income Taxes

19. INCOME TAXES

As a result of its indirect investment in Lazard Group, Lazard Ltd, through certain of its subsidiaries, is subject to U.S. federal income taxes on its portion of Lazard Group's operating income. Although a portion of Lazard Group's income is subject to U.S. federal income taxes, Lazard Group primarily operates in the U.S. as a limited liability company that is treated as a partnership for U.S. federal income tax purposes. As a result, Lazard Group's income from its U.S. operations is generally not subject to U.S. federal income taxes because such income is attributable to its partners. In addition, Lazard Group is subject to UBT which is attributable to Lazard Group's operations apportioned to New York City. UBT is incremental to the U.S. federal statutory tax rate. Outside the U.S., Lazard Group operates principally through subsidiary corporations that are subject to local income taxes.

The components of the Company's provision for income taxes for the years ended December 31, 2011, 2010 and 2009, and a reconciliation of the U.S. federal statutory income tax rate to the Company's effective tax rates for such periods are shown below.

See Note 23 of Notes to Consolidated Financial Statements regarding operating income (loss) by geographic region.

Deferred income taxes are provided for the effects of temporary differences between the tax basis of an asset or liability and its reported amount in the consolidated statements of financial condition. These temporary differences result in taxable or deductible amounts in future years. Details of the Company's deferred tax assets and liabilities, which are included in "other assets" and "other liabilities", respectively, on the consolidated statements of financial condition, are as follows:

	December 31,
	2011			2010
Deferred Tax Assets:
Basis adjustments (primarily as a result of the separation and recapitalization transactions that occurred during 2005 and from secondary offerings)	$	846,252		$	877,143
Compensation and benefits		196,133			207,080
Net operating loss and tax credit carryforwards		209,781			156,798
Depreciation and amortization		1,519			14,785
Other		25,410			39,316
Gross deferred tax assets		1,279,095			1,295,122
Valuation allowance		(1,145,257	)		(1,165,274	)
Total deferred tax assets (net of valuation allowance)	$	133,838		$	129,848
Deferred Tax Liabilities:
Depreciation and amortization	$	16,240		$	16,469
Compensation and benefits		10,729			20,563
Goodwill		15,031			9,839
Other		41,581			35,201
Total deferred tax liabilities	$	83,581		$	82,072

The basis adjustments recorded as of December 31, 2011 and 2010 are the result of:

• purchases and redemptions of historical and working member interests consummated in connection with the separation and recapitalization of the Company, which resulted in deferred tax assets of $176,871 and $196,049 at December 31, 2011 and 2010, respectively,

• tax basis step-ups resulting from the exchange of LAZ-MD exchangeable interests and from secondary offerings, and associated with LAM Merger which in the aggregate resulted in deferred tax assets of $638,069 and $640,720 at December 31, 2011 and 2010, respectively,

• tax basis step-up for U.S. income tax purposes on certain U.K. assets, which resulted in deferred tax assets of $24,338 and $32,455 at December 31, 2011 and 2010, respectively, and

• tax basis step-up for payments made under the tax receivable agreement of $6,974 and $7,919 at December 31, 2011 and 2010, respectively.

Although we have been profitable on a consolidated basis in the last two years, certain of our tax-paying entities have individually experienced pre-tax losses on a cumulative three-year basis primarily due to permanent differences between net income and taxable income at such entities. Considering these losses and the other factors listed below, we have recorded valuation allowances on our deferred tax assets of $1,145,257 and $1,165,274 as of December 31, 2011 and December 31, 2010, respectively. If these entities achieve sustainable levels of profitability in the future, we believe there is a reasonable possibility that the valuation allowance recorded against our deferred tax assets at such entities could be reduced significantly. The valuation allowance at December 31, 2011 reflects a net decrease of $20,017 from the balance of $1,165,274 at December 31, 2010.

The Company had net operating loss and tax credit carryforwards for which related deferred tax assets were recorded at December 31, 2011 primarily relating to:

(i) indefinite-lived carryforwards (subject to various limitations,) of approximately $50,800, primarily in the U.K. and Italy, and

(ii) certain carryforwards of approximately $137,100 in the U.S., which begin expiring in 2029.

As a result of certain realization requirements regarding share-based incentive plan awards, certain deferred tax assets pertaining to tax deductions related to equity compensation in excess of compensation recognized for financial reporting that would otherwise have been recognized at December 31, 2011 and 2010 of $19,900 and $9,065, respectively, are not included in the table above. The impact of such excess tax deductions will be recorded in stockholders' equity if and when such deferred tax assets are ultimately realized.

With few exceptions, the Company is no longer subject to income tax examination by foreign tax authorities and by U.S. federal, state and local tax authorities for years prior to 2007. While we are under examination in various tax jurisdictions with respect to certain open years, the Company believes that the result of any final determination related to these examinations is not expected to have a material impact on its financial statements. Developments with respect to such examinations are monitored on an ongoing basis and adjustments to tax liabilities are made as appropriate.

A reconciliation of the beginning to the ending amount of gross unrecognized tax benefits (excluding interest and penalties) for the years ended December 31, 2011, 2010 and 2009 is as follows:

	Year Ended December 31,
	2011			2010			2009
Balance, January 1 (excluding interest and penalties of $7,099, $7,247 and $5,467, respectively)	$	58,605		$	60,558		$	46,725
Increases in gross unrecognized tax benefits relating to tax positions taken during:
Prior years		1,081			2,184			5,271
Current year		16,928			15,756			18,251
Decreases in gross unrecognized tax benefits relating to:
Tax positions taken during prior years		(5,133	)		(644	)		–
Settlements with tax authorities		-			(3,805	)		–
Lapse of the applicable statute of limitations		(9,281	)		(15,444	)		(9,689	)
Balance, December 31 (excluding interest and penalties of $8,454, $7,099 and $7,247, respectively)	$	62,200		$	58,605		$	60,558

Additional information with respect to unrecognized tax benefits is as follows:

	Year Ended December 31,
	2011		2010			2009
Unrecognized tax benefits at the end of the year that, if recognized, would favorably affect the effective tax rate (includes interest and penalties of $8,454, $7,099 and $7,247, respectively)	$	44,545	$	39,112		$	41,405
Offset to deferred tax assets for unrecognized tax benefits	$	26,109	$	26,592		$	26,400
Interest and penalties recognized in current income tax expense (after giving effect to the reversal of interest and penalties of $1,785, $2,430 and $1,223, respectively)	$	1,355	$	(148	)	$	1,780

The Company anticipates that it is reasonably possible that the total amount of unrecognized tax benefits recorded at December 31, 2011 will decrease within 12 months by an amount up to approximately $10,000 as a result of the lapse of the statute of limitations in various tax jurisdictions.

Tax Receivable Agreement

The redemption of historical partner interests in connection with the Company's separation and recapitalization that occurred in May 2005 and the subsequent exchanges through December 31, 2011 of LAZ-MD Holdings exchangeable interests for shares of Class A common stock have resulted, and future exchanges of LAZ-MD Holdings exchangeable interests for shares of Class A common stock may result, in increases in the tax basis of the tangible and/or intangible assets of Lazard Group. Included in our deferred tax assets as of December 31, 2011 are approximately $709,000 related to certain basis step-up assets and approximately $137,000 of net operating losses generated by the amortization of such step-up assets. The tax receivable agreement dated as of May 10, 2005 with LFCM Holdings requires the Company to pay LFCM Holdings 85% of the cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes as a result of the above-mentioned increases in tax basis. During the years ended December 31, 2011, 2010 and 2009, the Company recorded a "provision (benefit) pursuant to tax receivable agreement" on the consolidated statements of operations of $429, $2,361 and $(1,258), respectively, with the liability related thereto at December 31, 2011 and 2010 of $2,790 and $2,361, respectively, included within "related party payables" on the consolidated statements of financial condition (see Note 21 of Notes to Consolidated Financial Statements). During the year ended December 31, 2009, the Company recorded a benefit related to the tax receivable agreement as a result of certain adjustments to previously recorded estimated provisions.
