PART I

Item 1. Business

Overview

Cohen & Steers, Inc. (CNS), a Delaware corporation formed in 2004, together with its wholly-owned subsidiaries, is a leading global investment manager with a long history of innovation and a focus on real assets, including real estate, infrastructure and commodities, along with preferred securities and other income solutions. CNS and its subsidiaries are collectively referred to as the Company, we, us or our. Headquartered in New York City, with offices in London, Hong Kong, Tokyo and Seattle, we serve institutional and individual investors around the world.

CNS was organized as a Delaware corporation on March 17, 2004. CNS is the holding company for its direct and indirect subsidiaries, including Cohen & Steers Capital Management, Inc. (CSCM), Cohen & Steers Securities, LLC (CSS), Cohen & Steers Asia Limited (CSAL), Cohen & Steers UK Limited (CSUK) and Cohen & Steers Japan, LLC.

Our revenue is derived primarily from investment advisory fees received from institutional accounts and investment advisory, administration, distribution and service fees received from open-end mutual funds and closed-end funds. These fees are based on contractually specified percentages of the value of the managed assets in each client's portfolio. Revenue fluctuates with changes in the total value of the portfolios and is recognized over the period that the assets are managed.

At December 31, 2014, we managed $53.1 billion in assets - $26.2 billion in institutional accounts, $17.1 billion in open-end mutual funds, and $9.8 billion in closed-end funds. The assets we manage increased 16% from $45.9 billion at December 31, 2013 as a result of market appreciation of $9.1 billion, offset by net outflows of $1.9 billion.

Account Types

We manage three types of accounts: institutional accounts, open-end mutual funds and closed-end funds.

Institutional Accounts

Institutional accounts for which we are the investment adviser represent portfolios of securities we manage for institutional clients. We manage the assets in each institutional account in a manner tailored to the investment requirements of that client as set forth in such client's investment advisory agreement. Our investment advisory agreements with the institutional account clients are generally terminable at any time. For the years ended December 31, 2014, 2013 and 2012, investment advisory fees from our institutional accounts totaled approximately $81.9 million, $81.8 million and $88.6 million, respectively, and accounted for 28%, 30% and 36%, respectively, of investment advisory and administrative fee revenue.

Subadvisory assets, which represent vehicles sponsored by third-party asset managers, are included in our institutional account assets. Subadvisory assets represent accounts for which we have been appointed as a subadvisor by the investment adviser to that account. As subadvisor, we are responsible for managing the portfolio's investments, while the investment adviser oversees our performance as subadvisor.

Open-end Mutual Funds

The open-end mutual funds for which we are the investment adviser offer and issue new shares continuously as assets are invested and redeem shares when assets are withdrawn. The share price for purchases and redemptions of each of the open-end mutual funds is determined by each fund's net asset value, which is calculated at the end of each business day. The net asset value per share is the current value of a fund's assets less liabilities, divided by the fund's total shares outstanding.

Investment advisory fees for the open-end mutual funds vary based on each fund's investment strategy, fees charged by other comparable mutual funds and the market in which the mutual fund is offered. In addition, we receive a separate fee for providing administrative services to each open-end mutual fund at a rate that is designed to reimburse us for the cost of providing these services. Each of the open-end mutual funds pays us a monthly investment advisory and administration fee based on a percentage of the value of the fund's average assets under management. For the years ended December 31, 2014, 2013 and 2012, investment advisory and administrative fees from our open-end mutual funds totaled approximately $127.4 million, $114.7 million and $96.3 million, respectively, and accounted for 44%, 42% and 39%, respectively, of investment advisory and administrative fee revenue.

1

Our investment advisory and administration agreements with the open-end mutual funds are generally terminable upon a vote of a majority of the fund's Board of Directors on 60 days' notice, and each investment advisory agreement, including the fees payable thereunder, is subject to annual approval, after the first two years, by a majority of the directors of the mutual fund's board who are not "interested persons," as defined by the Investment Company Act of 1940 (the “Investment Company Act”).

Closed-end Funds

The closed-end funds for which we are the investment adviser are registered investment companies that have issued a fixed number of shares through public offerings. These shares are listed on the New York Stock Exchange and cannot be redeemed by the fund's shareholders. The trading price of the shares of a closed-end fund is determined by supply and demand in the marketplace, which means the shares may trade at a premium or discount to the net asset value of the fund.

Investment advisory fees for the closed-end funds vary based on each fund's investment strategy, fees charged by other comparable mutual funds and prevailing market conditions at the time each closed-end fund initially offered its shares to the public. In addition, we receive a separate fee for providing administrative services to eight of the nine closed-end funds at a rate that is designed to reimburse us for the cost of providing these services. For services under the investment advisory and administration agreements, the closed-end funds pay us a monthly fee based on a percentage of the value of the fund's average assets under management. For the years ended December 31, 2014, 2013 and 2012, investment advisory and administrative fees from our closed-end funds totaled approximately $82.5 million, $74.6 million and $59.7 million, respectively, and accounted for 28%, 28% and 24%, respectively, of investment advisory and administrative fee revenue.

Each of our investment advisory agreements with a closed-end fund is subject, following the initial two-year term, to annual approval by at least a majority of the independent directors of the fund's board. Our investment advisory and administration agreements with the closed-end funds are generally terminable upon a vote of a majority of the fund's Board of Directors on short notice.

Portfolio Consulting and Other Services

We maintain two proprietary indexes, Cohen & Steers Realty Majors Index (RMP) and Cohen & Steers Global Realty Majors Index (GRM). RMP is the basis for the iShares Cohen & Steers Realty Majors Index Fund sponsored by BlackRock Institutional Trust Company, N.A. GRM is the basis for Cohen & Steers Global Realty Majors ETF sponsored by ALPS Fund Services, Inc. and iShares Global Real Estate Index Fund (formerly, Claymore Global Real Estate ETF) sponsored by BlackRock Investments Canada Inc. (formerly, Claymore Investments, Inc.) We earn a licensing fee based on a percentage of the funds' assets for the use of our indexes, which assets, as of December 31, 2014, were approximately $3.6 billion. While we do collect a fee on these assets, they are not included in our reported assets under management.

We provide services in connection with model-based strategies (MBS) accounts. As portfolio consultant for a number of MBS accounts, we construct portfolios of securities that fulfill the investment objective of the mandate and supply portfolio models on a regular basis. As of December 31, 2014, we provided such advisory consulting services to MBS accounts with aggregate assets of $2.0 billion. While we do collect a fee on these assets, they are not included in our reported assets under management.

As portfolio consultant, we provide several services in connection with investment products such as unit investment trusts (UITs). A UIT is a registered investment company that holds a portfolio of securities that generally does not change during the life of the UIT (generally two to five years) except that the sponsor of the UIT may sell portfolio securities under certain narrowly defined circumstances. As portfolio consultant to a number of UITs, we construct a portfolio of securities that we believe is well suited to satisfy the investment objective of the UIT. We also provide ongoing portfolio monitoring services related to the portfolio. Finally, we provide a license to certain firms to use our name in connection with certain of their investment products. At December 31, 2014, we provided such advisory consulting services to UITs with aggregate assets of $902 million. While we do collect a fee on these assets, they are not included in our reported assets under management.

Our fee schedules for these relationships vary based on the type of services we provide for each relationship.

Our Investment Process

Each of our investment strategies has an investment process that is executed by specialist teams, each of which is led by a portfolio manager, or a team of portfolio managers, supported by dedicated analysts. These personnel are located in our New York, Seattle, London and Hong Kong offices. Each team executes fundamentally driven, actively managed investment strategies and each has a unique and well defined process that includes top-down macroeconomic and bottom-up fundamental research and portfolio management elements. These teams are subject to multiple levels of oversight and support from our President and Chief Investment Officer, Joseph Harvey, our Investment Risk Committee and our Legal and Compliance

2

department. Certain of our strategies may involve multiple asset classes and are overseen by investment committees led by senior portfolio managers of our specialist teams.

We offer the following strategies:

Real Assets invests in a diversified portfolio of companies and securities that own or are backed by tangible real assets, including real estate securities, global listed infrastructure, commodities and natural resource equities, with the objective of achieving attractive total returns over the long term, while providing diversification and maximizing the potential for real returns in periods of rising inflation.

Our Distribution Network

Our distribution network encompasses the major channels in the asset management industry, including large brokerage firms, registered investment advisers and institutional investors. The open-end mutual funds for which we are the investment adviser are available for purchase with and without commissions through full service and discount broker/dealers and the significant networks serving financial advisers. We provide advisory and administration services to our open-end mutual funds and closed-end funds under the Cohen & Steers brand name.

Our institutional account relationships include institutions such as corporate and public pensions, endowments and foundations and insurance funds. As of December 31, 2014, approximately $18.9 billion of our institutional account assets were subadvisory assets managed for investment managers of several mutual funds and variable annuity funds. These funds are sponsored by other financial institutions and are distributed in the United States, Canada, Europe, Australia and Japan.

Competition

We compete with a large number of global and U.S. investment advisers, commercial banks, broker/dealers, insurance companies and other financial institutions. With approximately $53.1 billion in assets under management as of December 31, 2014, we are considered a small to mid-sized global investment manager. Many competing firms are parts of larger financial services companies and attract business through numerous channels, including retail banking, investment banking and underwriting contacts, insurance agencies and broker/dealers.

We face various sources of competition in wealth management and institutional channels. Our direct competitors in wealth management are other mutual fund and exchange-traded-fund (ETF) sponsors, including large nationally recognized investment advisory firms that offer products for more or different asset classes than we do and smaller boutique firms that specialize in fewer or particular asset classes. We also compete against advisors who offer wealth management clients the ability to manage separate-account portfolios. In the institutional channel, we compete against a large pool of investment managers offering similar products and services, from boutique establishments to major commercial and investment banks.

Performance, price and brand are the principal factors of competition. Prospective clients and mutual fund shareholders will typically base their decisions to invest or continue to invest with us on our ability to generate returns in excess of a market index and the cost of doing so. In other words, we are judged on our performance and our fees relative to competitors. Individual mutual fund holders may also base their decision on the ability to access the mutual funds we manage through a particular distribution channel. For institutional accounts, clients are often advised by consultants, who may include other factors in their decisions for these clients.

We have seen increasing interest by institutional and individual investors in real assets, including real estate, infrastructure, natural resources and commodities, along with preferred securities and other income solutions. While this has attracted more assets into these classes, it has also increased competition from other managers that are competing for the same client base that we serve. Financial intermediaries that offer our products to their clients may also offer competing products. Many of our competitors have greater brand name recognition and more extensive client bases than we do, which could be to our disadvantage. In addition, our larger competitors have more resources and may have more leverage to expand their distribution channels and capture market share through ongoing business relationships and extensive marketing efforts. However, relative to our larger competitors, we may be able to grow our business at a faster rate from a relatively smaller asset base. In addition, we believe we are able to shift resources in response to changing market conditions more quickly than many larger investment advisory firms.

4

The open-end mutual funds for which we are the investment adviser face significant competition from other open-end mutual funds, ETFs and other public investment companies and private hedge funds. Advertising, sales promotions, the type and quality of services offered and investment performance influence competition for sale of open-end mutual funds.

Regulation

The Company is subject to regulation under U.S. federal and state laws, as well as applicable laws in the other jurisdictions in which we do business. Violation of applicable laws or regulations could result in fines, temporary or permanent prohibition of engagement in certain activities, reputational harm and related client terminations, suspensions of personnel or revocation of their licenses, suspension or termination of investment adviser or broker/dealer registrations, or other sanctions.

Investment Adviser Regulation

As U.S. registered investment advisers, our subsidiaries, CSCM, CSAL and CSUK are regulated by the Securities and Exchange Commission (the SEC) and are subject to the rules and regulations of the Investment Advisers Act of 1940 (the Advisers Act) and various state laws and regulations. The Advisers Act imposes numerous obligations on registered investment advisers, including recordkeeping, operational and marketing requirements, disclosure obligations and prohibitions on fraudulent activities. Our subsidiaries that serve as investment adviser or subadviser to U.S. registered mutual funds are also subject to the Investment Company Act, which imposes additional governance, compliance, reporting and fiduciary obligations. We also manage or subadvise funds that are domiciled and regulated outside the U.S. and are subject to regulation by local securities regulators. CSCM and CSUK are regulated by the Luxembourg Commission de Surveillance de Secteur Financier in their capacity as investment manager of undertakings for collective investment in transferable securities domiciled in Luxembourg, which imposes its own obligations and restrictions similar in type to those we are subject to in the U.S.

Outside the U.S., our subsidiary CSUK provides investment management services in the United Kingdom. The activities of CSUK are regulated by the United Kingdom Financial Conduct Authority (the FCA) and subject to the Financial Services and Markets Act 2000 (the FSMA). Under the FSMA, CSUK is subject to certain liquidity and capital resources requirements, among other things. Such requirements may limit our ability to withdraw capital from CSUK.

In addition, CSUK must comply with certain European regulations, including the Markets in Financial Instruments Directive (MiFID), the Capital Requirements Directive and the Alternative Investment Fund Managers Directive (AIFMD). MiFID regulates the provision of investment services throughout the European Economic Area and the Capital Requirements Directive delineates regulatory capital requirements. AIFMD regulates the management, administration and marketing of alternative investment funds domiciled in or marketed within the European Union and establishes a regime for the cross-border marketing of those funds, which are activities our subsidiaries currently engage, or may seek to engage, in.

CSAL provides investment management services in the Hong Kong Special Administrative Region of the People’s Republic of China. The activities of CSAL are regulated by the Hong Kong Securities and Futures Commission (the SFC) and are subject to the Securities and Futures Ordinance (the SFO), which regulates, among other things, offers of investments to the public and the licensing of intermediaries. CSAL and its employees conducting any of the regulated activities specified in the SFO are required to be licensed with the SFC and are subject to the rules, codes and guidelines issued by the SFC from time to time.

Because of the global and integrated nature of our business, regulation applicable to an affiliate in one jurisdiction may affect the operation of affiliates in others or require compliance at a group level.

Securities and Commodities Regulation

Our trading and investment activities are subject to the regulations of securities exchanges around the world and the rules, regulations and regulators that supervise such exchanges, including the SEC. These regulations include those governing insider trading, market manipulation, trading requirements (e.g., volume limitations and reporting obligations) as well as market regulation policies.

CSCM is a registered commodity trading advisor (CTA) and a registered commodity pool operator (CPO) with the Commodities Futures Trading Commission (the CFTC) and is a member of the National Futures Association (the NFA), a futures industry self-regulatory organization, in such capacities. The CFTC and NFA each regulate futures contracts, swaps (as a result of the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act)), and various other financial instruments in which certain of the Company’s clients may invest.

Our subsidiary, CSS, is a registered broker/dealer subject to regulations of the SEC, the Financial Industry Regulatory Authority and other federal and state agencies. CSS is subject to regulations governing, among other things, sales practices,

5

market making and trading among broker/dealers, use and safekeeping of clients' funds and securities, capital structure, and recordkeeping. CSS is also subject to the SEC’s net capital rule, which specifies minimum net capital levels for registered broker/dealers and is designed to enforce minimum standards regarding the general financial condition and liquidity of broker/dealers. Under certain circumstances, this rule may limit our ability to withdraw capital and receive dividends from CSS.

New and Pending Changes in Regulation

The European Commission (the EC) reviewed MiFID and produced MiFID II and the Markets in Financial Instruments Regulation (MiFIR), which were adopted by the European Parliament and the European Council. MiFID II and MiFIR entered into force on July 2, 2014, however, implementation of the final rules under MiFID II and MiFIR is not expected until January 2017. The final rules may result in changes to pre- and post-trade reporting obligations, administration of commissions and commission disclosure obligations and an expansion of the types of instruments subject to these requirements, as well as changes to a variety of other areas. The final rules may affect the buying and selling of derivatives by moving most derivatives trading onto regulated trading venues and may control the activities of algorithmic trading, conduct of business requirements and selling practices, intermediary inducements and client categorization.

For additional information on the impact of regulatory changes, see Item 1A. Risk Factors.

Employees

As of December 31, 2014, we had 263 full-time employees.

Available Information

We file annual, quarterly and current reports, proxy statements and all amendments to these reports and other information with the SEC. We make available free of charge on or through our website at www.cohenandsteers.com our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K (and all amendments to those reports) as soon as reasonably practicable after such reports are electronically filed with or furnished to the SEC.

Item 1A. Risk Factors

Risks Related to Our Business

A significant portion of our revenue for 2014 was derived from a single institutional client.

At December 31, 2014, our largest institutional client, which holds accounts across numerous strategies and in subadvisory and model-based assignments and products, represented approximately 13% of our total revenue for 2014. Approximately 50% of the institutional account assets we managed and approximately 25% of the total assets we managed were derived from this client. In addition, approximately 15% of our assets under advisement was derived from this client. Loss of, or significant withdrawal from, any of these accounts would reduce our revenue.

A decline in the performance of real estate securities could have an adverse effect on the assets we manage and our revenue.

As of December 31, 2014, a majority of the assets we managed were concentrated in real estate securities. Real estate securities and real property investments owned by the issuers of real estate securities are subject to varying degrees of risk that could affect any returns we realize. Returns on investments in real estate securities depend on the amount of income and capital appreciation or loss realized by the underlying real property. Income and real estate values may be adversely affected by, among other things, the cost of compliance with applicable laws, interest rates, the availability of financing, the creditworthiness of the tenants, and the limited ability of issuers of real estate securities to vary their portfolios promptly in response to changes in economic or other conditions. If the underlying properties do not generate sufficient income to meet operating expenses, the income and the ability of an issuer of real estate securities to pay interest and principal on debt securities or any dividends on common or preferred stocks will be adversely affected. A decline in the performance of real estate securities could reduce the value of the assets we manage, reducing the fees we earn and our revenue.

Fluctuations in the underlying value of the assets we manage could adversely impact revenues and earnings.

Our investment advisory and management revenues are primarily comprised of fees based on a percentage of the value of assets under management and, in some cases, performance fees normally expressed as a percentage of the returns in excess of a benchmark. Numerous factors, including movements in equity, debt, commodity, real estate and alternative investment asset prices, interest rates or foreign exchange rates or the loss, or reduction in size of, client accounts could cause: (i) the value of our assets under management to decrease, (ii) the returns realized on assets under management to decrease, (iii) clients to withdraw funds in favor of products that they perceive offer greater opportunity or safety than our products, (iv)

6

clients to rebalance assets away from products that we manage into products that we may not manage, and (v) clients to rebalance assets away from products that earn higher fees into products with lower fees. The occurrence of any of these events could result in lower investment advisory, management, administration and performance fees and cause the Company’s revenues and earnings to decline.

Our clients and partners may withdraw or reduce the assets we manage or otherwise change the terms of our relationship which could have an adverse impact on our assets under management and revenue.

Our institutional clients, and firms with which we have strategic alliances, may terminate their relationship with us, reduce the aggregate amount of assets we manage, shift their funds to other types of accounts with different fee structures, or renegotiate the fees we charge them for any number of reasons, including investment performance, changes in prevailing interest rates and financial market performance. Certain investors in the mutual funds that we manage hold their shares indirectly through platforms sponsored by financial institutions that have the authority to make investment and asset allocation decisions on behalf of such shareholders. Any such decision may cause the fund to sell assets at a disadvantageous time or price which could negatively affect the value of our assets under management. In a declining market or conditions of poor relative or absolute performance, the pace of mutual fund redemptions and withdrawals and the loss of institutional and individual separate account clients could accelerate. The occurrence of any of these events could have a material adverse effect on assets under management and revenue.

Increased competition from investment managers that charge lower fees may force us to reduce the fees we charge for our services which could have a negative impact on our revenues.

Increased competition from investment managers, including passive investment managers, that offer products and services at lower fees has resulted in downward pressure on fees in certain segments of the investment management industry. In order to maintain our fee structure in a competitive environment, we must be able to provide clients with investment returns and service that will encourage them to be willing to pay our fees. In the event our competitors charge lower fees for substantially similar products and services, we may be forced to reduce our fees in order to attract and retain clients, which could have a negative impact on our revenues.

Our growth may be constrained by the size and number of real estate securities issuers, as well as real estate investment trust ownership restrictions.

Investments in real estate securities continue to play an important role in our overall business strategy. Our ability to continue to increase our ownership of real estate securities depends in part on growth in the size and number of issuers in the real estate securities market, particularly in the U.S. Our ability to increase our ownership is also constrained by REIT ownership limits which limit ownership of a REIT’s outstanding capital stock, common stock, and/or preferred stock. Although certain REITs in which we invest have granted us waivers from these ownership limits to allow greater investment, such REITs retain the right to revoke or reduce the waiver limits at any time. As a result of these constraints, we have in the past, and may in the future, be prevented from acquiring new or additional real estate securities, which may impair our ability to increase the assets we manage and our revenue.

The inability to access clients through third-party intermediaries could have a material adverse effect on our business.

In recent years, a significant portion of the growth we have experienced in the assets we manage has been from assets obtained through third-party intermediaries. Our ability to distribute our mutual funds is highly dependent on access to the client bases and product platforms of international, national and regional securities firms, banks, insurance companies, defined contribution plan administrators and other intermediaries which generally offer competing investment products. In addition, our separate account asset management business and subadvisory services depend in part on recommendations by consultants, financial planners and other professional advisers, as well as our existing clients.

The structure and terms of the distribution arrangements with intermediaries, including fees paid by us or our mutual funds to intermediaries to assist with distribution efforts and the ability of our mutual funds to participate in these intermediary platforms, are subject to changes driven by market competition and regulatory developments. There can be no assurance that we will be able to retain access to these channels. Loss of any of these third-party distribution channels, or changes to their structure and terms, or any reduction in our ability to access clients and investors through existing and new distribution channels, could adversely affect our business.

7

Limitations on our ability to utilize leverage in the closed-end funds we sponsor could reduce our assets under management and revenue.

Certain of the closed-end funds sponsored by us utilize leverage in the form of bank financing, which in the aggregate amounted to $2.4 billion as of December 31, 2014. To the extent any closed-end fund sponsored by us elects or is required by regulation or the terms of its bank financing to reduce leverage, such fund may need to liquidate investments. Reducing leverage or liquidation during adverse market conditions could reduce the Company's assets under management and revenue.

Our financial performance could be negatively affected if we are unable to attract and retain qualified personnel.

Our financial performance is largely dependent on the talents and efforts of highly skilled personnel. Specifically, our continued ability to compete in our business, to manage our business effectively and to continue to execute our overall strategy depends on our ability to attract and retain highly skilled and qualified portfolio managers, investment analysts, marketing and client services personnel and other key personnel, including our executive officers, many of whom have specialized expertise and extensive experience in our industry. Our ability to attract and retain personnel depends on numerous factors, including without limitation, culture, compensation, career development, the management and leadership of the Company. If we are unable to continue to attract and retain qualified personnel for any reason, our performance, including our competitive position, the successful execution of our overall strategy and our results of operations could be negatively impacted.

Failure to comply with client contractual requirements and/or investment guidelines could result in payments to clients and loss of revenue.

In general, when clients retain the Company to manage assets or provide products or services on their behalf, they specify investment guidelines and contractual requirements that the Company is required to observe in the provision of its services. These investment guidelines and contractual requirements set forth the overall investment objective, performance and reporting obligations, investable securities and the criteria for portfolio management. A failure to comply with these guidelines and/or contractual requirements could result in clients seeking to recover losses, withdrawing their funds or terminating their agreements with us, which could cause the Company's revenue to decline.

We could suffer financial losses in earnings or revenue if our reputation is harmed.

Our reputation is important to the success of our business. We believe that the Cohen & Steers brand has been, and continues to be, well received both in our industry and with our clients, reflecting the fact that our brand, like our business, is based in part on trust and confidence. Our reputation may be harmed by a number of factors, including, but not limited to, poor investment performance, the dissemination by current or former clients of unfavorable opinions relating to our services, and the imposition of legal or regulatory sanctions or penalties in connection with our business activities. If our reputation is harmed, existing clients may reduce amounts held in, or withdraw entirely from, funds or accounts that we advise, or funds or accounts may terminate their relationship with us, which could reduce our assets under management. In addition, reputational harm may cause us to lose current employees and we may be unable to continue to attract new ones with similar qualifications or skills. If we fail to address, or appear to fail to address, successfully and promptly the underlying causes of any reputational harm, we may be unsuccessful in repairing any existing harm to our reputation and our future business prospects would likely be affected. The loss of either client relationships or personnel could reduce our assets under management, revenue and earnings.

Support provided to new products may reduce fee income, increase expenses and expose us to potential loss on invested capital.

From time to time, we may support the development of new investment products by waiving a portion of the fees we receive for managing such products, by subsidizing expenses or by making seed investments. Seed investments in new products utilize Company capital that would otherwise be available for general corporate purposes. Seed investments may be subject to losses due to market declines. Loss on invested capital used to support new products could have an adverse impact on our financial condition.

Regulations restricting the use of commission credits to pay for research could result in increased expenses.

On behalf of our clients, we make decisions to buy and sell securities, select broker/dealers to execute trades and negotiate brokerage commission rates. In connection with these transactions, we may receive commission credits to pay for research from broker/dealers that have the effect of reducing certain of our expenses. New regulations in and outside the U.S. may restrict or eliminate the Company’s ability to use commission credits to pay for research, which could increase our operating expenses.

8

The growth of our business could be adversely affected if we are unable to manage the costs associated with the implementation of our business strategy.

Our business strategy continues to involve diversifying our investment management business to include products and services outside investments in U.S. real estate securities. As part of the implementation of our strategy, we have emphasized the development of broader real assets strategies, including commodities and infrastructure, and have expanded our geographical presence outside the U.S. This has entailed hiring additional portfolio managers and additional personnel to support our strategies. As a result, our fixed costs and other expenses have increased as a result of expenses incurred to support the development of new strategies and to enhance our infrastructure, including additional office space, increased travel and additional technology and compliance resources. The success of our business strategy and future growth is contingent upon our ability to continue to support development and implementation of new strategies and products and our ability to successfully manage multiple offices and navigate legal and regulatory systems outside the U.S. In the future, we may not have sufficient resources to adequately support our growth.

We could incur financial losses, reputational harm, and regulatory penalties if we fail to properly safeguard sensitive and confidential information and fail to implement effective information and cyber security policies, procedures and capabilities.

We are dependent on the effectiveness of our information and cyber security policies, procedures and capabilities to protect our computer, network and telecommunications systems and the data that reside in or are transmitted through them.

As part of our normal operations, we maintain and transmit confidential information about our clients as well as proprietary information relating to our business operations. We maintain a system of internal controls designed to provide reasonable assurance that fraudulent activity, including misappropriation of assets, fraudulent financial reporting, and unauthorized access to sensitive or confidential data is either prevented or timely detected. However, our technology systems may still be vulnerable to unauthorized access or may be corrupted by cyber attacks, computer viruses or other malicious software code, or authorized persons could inadvertently or intentionally release confidential or proprietary information. Although we take precautions to password protect and encrypt our mobile electronic hardware, if such hardware is stolen, misplaced or left unattended, it may become vulnerable to hacking or other unauthorized use, creating a possible security risk and resulting in potentially costly actions by us. Breach of our technology systems could result in the loss of valuable information, liability for stolen assets or information, remediation costs to repair damage caused by the breach, additional security costs to mitigate against future incidents and litigation costs resulting from the incident. Moreover, loss of confidential client identification information could harm our reputation, result in the termination of contracts by our existing clients and subject us to liability under laws that protect confidential personal data, resulting in increased costs or loss of revenues. We do not currently maintain insurance coverage that would cover or limit our out-of-pocket losses related to cyber risks. As such, we would be liable for all losses in connection with a cyber attack.

Failure to maintain adequate business continuity plans could have a material adverse effect on the Company and its products.

Significant portions of our business operations and those of our critical third-party service providers are concentrated in a few geographic areas, including New York and New Jersey. Critical operations that are geographically concentrated in New York include trading operations, information technology, fund administration, and portfolio accounting services for the Company’s products. Should we, or our critical service providers, experience a significant local or regional disaster or other business continuity problem, our ability to remain operational will depend in part on the safety and availability of our personnel, our office facilities, and the proper functioning of our computer, network, telecommunication and other related systems and operations. The failure by us, or our critical service providers, to maintain updated adequate business continuity plans, including backup facilities, could impede our ability to operate in the event of a disruption, which could cause our earnings to decline. We have developed various backup systems and contingency plans but we cannot be assured that they will be adequate in all circumstances that could arise or that material interruptions and disruptions will not occur. In addition, we rely to varying degrees on outside vendors for disaster recovery support, and we cannot be assured that these vendors will be able to perform in an adequate and timely manner. If we, or our critical service providers, are unable to respond adequately to such an event in a timely manner, we may be unable to continue our business operations, which could lead to a damaged reputation and loss of clients resulting in a decrease in assets under management and lower revenues.

9

The failure of a key vendor to fulfill its obligations to the Company could have a material adverse effect on the Company and its products.

We depend on a number of key vendors for various fund administration, accounting, custody and transfer agent roles and other operational needs. The failure or inability of the Company to diversify its sources for key services or the failure of any key vendors to fulfill their obligations could lead to operational issues for the Company and certain of its products, which could result in financial losses for the Company and its clients.

Risks Related to our Common Stock

A majority of our common stock is owned by our Executive Chairman and Chief Executive Officer, whose interests may differ from those of other stockholders.

Our Executive Chairman and Chief Executive Officer beneficially owned approximately 52% of our common stock as of February 23, 2015. As long as our Executive Chairman and Chief Executive Officer own a majority of our common stock, they will have the ability to, among other things:

• elect all of the members of our board of directors and thereby control the management and affairs of the Company;

• determine the outcome of matters submitted to a vote of our stockholders; and

• preclude any unsolicited acquisition of us and, consequently, adversely affect the market price of our common stock or prevent our stockholders from realizing a premium on their shares.

The interests of our Executive Chairman and Chief Executive Officer may differ from those of other stockholders in instances where, for example, management compensation is being determined or where an unsolicited acquisition of us could result in a change in our management. The concentration of beneficial ownership in our Executive Chairman and Chief Executive Officer may limit the ability of our other stockholders to influence the affairs of the Company.

Sales of a substantial number of shares of our common stock may adversely affect the market price of our common stock, and the issuance of additional shares will dilute your percentage ownership in the Company.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could adversely affect the market price of our common stock. Our Executive Chairman and Chief Executive Officer, who beneficially owned, in the aggregate, 23,613,084 shares of our common stock as of February 23, 2015, may sell shares of our common stock in the open market, subject to any restrictions imposed by U.S. federal securities laws on sales by affiliates.

In addition, in connection with our initial public offering in 2004, we entered into a Registration Rights Agreement with our Executive Chairman and Chief Executive Officer and certain of their affiliates which requires us to register under the Securities Act of 1933, as amended (the “Securities Act”), shares of our common stock (and other securities convertible into or exchangeable or exercisable for shares of common stock) held by them under certain circumstances. In August 2012, we filed a Registration Statement on Form S-3 covering (i) the resale of an aggregate of 12,000,000 shares owned by our Executive Chairman and Chief Executive Officer and (ii) the offer and sale of 10,000,000 shares by us to the public. The registration statement was declared effective by the SEC in September 2012. On or prior to expiration of the registration statement in September 2015, we plan to file another registration statement covering the registered shares and may offer these shares to the public. The sale of a substantial number of shares of our common stock may adversely affect the market price of our common stock and any additional shares that we issue will dilute your percentage ownership in the Company.

Anti-takeover provisions in our charter documents and Delaware law may delay or prevent a change in control of us, which could decrease the trading price of our common stock.

Our certificate of incorporation and bylaws and Delaware law contain certain anti-takeover provisions that could have the effect of making it more difficult for a third-party to acquire, or of discouraging a third-party from attempting to acquire, control of the Company without negotiating with our board of directors. Such provisions could limit the price that certain investors might be willing to pay in the future for the Company’s securities. Certain of these provisions allow the Company to issue preferred stock with rights more senior to those of the common stock, impose various procedural and other requirements which could make it more difficult for stockholders to effect certain corporate actions and set forth rules regarding how stockholders may present proposals or nominate directors for election at annual meetings.

We believe these provisions protect our stockholders from coercive or other unfair takeover tactics by requiring potential acquirers to negotiate with our board of directors and by providing our board of directors with more time to assess

10

acquisition proposals. However, these provisions apply even if an acquisition proposal may be considered beneficial by some stockholders and could have the effect of delaying or preventing an acquisition. In the event that our board of directors determines that a potential business combination transaction would be beneficial to the Company and its stockholders, such stockholders may elect to sell their shares in the Company and the trading price of our common stock could decrease.

Regulatory and Legal Risks

We may be adversely impacted by legal and regulatory changes in the U.S. and internationally.

Our regulatory environment is frequently altered by new regulations and revisions to, and evolving interpretations of, existing regulations. Future changes could require us to modify or curtail our investment offerings and business or impact our expenses and profitability.

In the U.S., regulations under the Dodd-Frank Act relating to regulation of swaps and derivatives have impacted the manner in which Company-advised funds and accounts use and trade swaps and other derivatives, which has increased the cost of derivatives trading conducted by the Company on behalf of its clients. Compliance with these regulations has required the development and implementation of new mechanisms to monitor compliance with SEC and CFTC rules relating to, among other things, the registration and regulation of CTAs and CPOs, the registration of counterparties that are swap dealers and other counterparties that are major participants in the swap markets, and mandatory clearing of certain swap transactions. The SEC, the Internal Revenue Service (IRS) and the CFTC each continue to review the use of futures and derivatives by mutual funds, which could result in additional regulations that limit the use of futures and derivatives by mutual funds.

In addition, the Company has begun reporting certain information about its private funds to the SEC and certain information about a number of its commodity pools to the CFTC pursuant to systemic risk reporting requirements adopted by both agencies, which have required, and will continue to require, investments in people and systems to assure timely and accurate reporting. Legislators, regulators, tax authorities and others worldwide continue to explore, on their own and in response to demands from the investment community, increased regulation related to private pools of capital, including changes with respect to investor eligibility, certain limitations on trading activities, marketing activities, the scope of anti-fraud protections and a variety of other matters, which could result in additional compliance costs.

Outside the U.S., the EC is in the process of formulating rules and regulations under MiFID II and MiFIR. These, together with the changes contemplated by AIFMD, will have direct and indirect effects on our operations in the European Economic Area, including marketing restrictions and increased compliance, disclosure and other obligations, which could impact our ability to expand in these markets.

The foregoing regulatory changes and other reforms, including changes to laws affecting the tax status of REITs, could affect our ability to conduct certain business activities.

Our involvement in legal proceedings could adversely affect our results of operations and financial condition.

Many aspects of our business involve risks of legal liability. Various claims against us arise in the ordinary course of business, including employment related claims. From time to time, we receive subpoenas or other requests for information from various U.S. and non-U.S. governmental and regulatory authorities and third parties in connection with certain industry-wide, company-specific or other investigations or proceedings. In addition, certain of the investment funds that the Company manages may become subject to lawsuits, any of which could potentially harm the investment returns of the applicable fund or result in the Company being liable to the applicable fund for any resulting damages.

We carry insurance in amounts and under terms that we believe are appropriate. We cannot guarantee that our insurance will cover most liabilities and losses to which we may be exposed, or that our insurance policies will continue to be available at acceptable terms and fees. Certain insurance coverage may not be available or may be prohibitively expensive in future periods. As our insurance policies come up for renewal, we may need to assume higher deductibles or pay higher premiums, which would increase our expenses and reduce our net income.

The tax treatment of certain of our funds involves the interpretation of complex provisions of U.S. federal income tax law for which no precedent may be available and may be subject to potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis.

The U.S. federal income tax treatment of our funds depends in some instances on determinations of fact and interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. U.S. federal income tax rules are constantly under review by persons involved in the legislative process, the IRS

11

and the U.S. Department of Treasury, frequently resulting in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations. Changes to the U.S. federal income tax laws and interpretations thereof could cause us to change our investments and commitments, affect the tax considerations of an investment in us and change the character or treatment of portions of our income. In addition, the Company may be required to make certain assumptions when electing a particular tax treatment. However, those assumptions may not be in compliance with all aspects of applicable tax requirements. It is possible that the IRS will assert successfully that the assumptions used by us do not satisfy the technical requirements of the Internal Revenue Code and/or Treasury Regulations and could require items of income, gain, deductions, loss or credit, including interest deductions, be adjusted, reallocated or disallowed in a manner that adversely affects our clients.

Item 1B. Unresolved Staff Comments

The Company has no unresolved SEC comments.

Item 2. Properties

Our principal executive office is located in leased office space at 280 Park Avenue, New York, New York. In addition, we have leased office space in London, Hong Kong, Tokyo and Seattle.

Item 3. Legal Proceedings

From time to time, we may become involved in legal matters relating to claims arising in the ordinary course of our business. There are currently no such matters pending that we believe could have a material effect on our consolidated results of operations, cash flows or financial condition. From time to time, the Company receives subpoenas or other requests for information from various U.S. federal and state governmental authorities, domestic and foreign regulatory authorities and third parties in connection with certain industry-wide or other investigations or proceedings. It is the Company's policy to cooperate fully with such inquiries.

Item 4. Mine Safety Disclosures

Not applicable.

PART II

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

Our common stock is listed on the New York Stock Exchange (“NYSE”) and is traded under the symbol “CNS”. As of February 23, 2015, there were 28 holders of record of our common stock.

Payment of any dividends to our common stockholders is subject to the discretion of our Board of Directors. When determining whether to pay a dividend, our Board of Directors takes into account such matters as general economic and business conditions, our strategic plans, our financial results and condition, contractual, legal and regulatory restrictions on the payment of dividends by us and our subsidiaries and such other factors that our Board of Directors deems relevant. On February 26, 2015, we declared a quarterly cash dividend on our common stock in the amount of $0.25 per share. As set forth in the table above, we have historically paid quarterly cash dividends.

Assets under management were $53.1 billion at December 31, 2014, an increase of 16% from $45.9 billion at December 31, 2013 and an increase of 16% from $45.8 billion at December 31, 2012. The increase in assets under management during 2014 was due to market appreciation of $9.1 billion, including $6.7 billion from U.S. real estate, $1.4 billion from global/international real estate, $435 million from global listed infrastructure and $406 million from preferred securities, partially offset by net outflows of $1.9 billion, including net outflows of $1.7 billion from U.S. real estate, $1.7 billion from large cap value and $669 million from global/international real estate, partially offset by net inflows of $1.2 billion into preferred securities, $548 million into global listed infrastructure and $291 million into commodities, which is included in "Other." The increase in assets under management during 2013 was attributable to market appreciation of $2.1 billion, offset by net outflows of $2.0 billion, primarily from global/international real estate and large cap value strategies. The increase in assets under management during 2012 was attributable to market appreciation of $7.1 billion, partially offset by net outflows of $2.6 billion, primarily from global/international real estate strategies associated with subadvisory relationships.

A significant majority of our revenue, approximately 93%, 91% and 89% for the years ended December 31, 2014, 2013 and 2012, respectively, was derived from investment advisory and administrative fees for providing asset management services to institutional accounts and open-end mutual funds and closed-end funds sponsored by us. This revenue is earned pursuant to the terms of the underlying advisory and administration contracts, and is based on a contractual fee generally applied to the average assets under management in the client's portfolio.

Average assets under management was $50.6 billion for the year ended December 31, 2014, a 6% increase from $47.9 billion for the year ended December 31, 2013 and a 15% increase from $44.2 billion for the year ended December 31, 2012.

Assets under management in institutional accounts were $26.2 billion at December 31, 2014, compared with $22.9 billion at December 31, 2013 and $24.9 billion at December 31, 2012. The increase in assets under management during 2014 was due to market appreciation of $5.2 billion, including $3.7 billion from U.S. real estate, $1.2 billion from global/international real estate and $223 million from large cap value strategies, partially offset by net outflows of $2.1 billion, including net outflows of $1.6 billion from large cap value, $949 million from U.S. real estate and $565 million from global/international real estate, partially offset by net inflows of $392 million into global listed infrastructure and $382 million into preferred securities. The decrease in assets under management during 2013 was due to net outflows of $3.4 billion, primarily from global/international real estate and large cap value strategies, partially offset by market appreciation of $1.5 billion. The decrease in assets under management during 2012 was attributable to net outflows of $5.1 billion, primarily from global/international real estate strategies associated with subadvisory relationships, largely offset by market appreciation of $4.5 billion.

Average assets under management for institutional accounts was $24.9 billion for the year ended December 31, 2014, an increase of 1% from $24.7 billion for the year ended December 31, 2013 and a decrease of 2% from $25.3 billion for the year ended December 31, 2012.

The increase in assets under management during 2014 was due to market appreciation of $3.0 billion, including $2.6 billion from U.S. real estate, $206 million from global/international real estate and $194 million from preferred securities, and net inflows of $196 million, including net inflows of $831 million into preferred securities, $156 million into global listed infrastructure and $117 million into multi-strategy real assets, partially offset by net outflows of $779 million from U.S. real estate and $103 million from global/international real estate strategies. The increase in assets under management during 2013 was due to net inflows of $702 million, primarily from U.S. real estate and preferred securities strategies, and market appreciation of $352 million. The increase in assets under

17

management during 2012 was attributable to market appreciation of $1.9 billion and net inflows of $1.5 billion, primarily from U.S. real estate and preferred securities strategies.

The increase in assets under management during 2014 was due to market appreciation of $840 million. The increase in assets under management during 2013 was due to net inflows of $765 million, primarily from the launch of Cohen & Steers MLP Income and Energy Opportunity Fund, Inc. (MIE), and market appreciation of $215 million. The increase in assets under management during 2012 was attributable to inflows of $1.0 billion, primarily from the launch of Cohen & Steers Limited Duration Preferred and Income Fund, Inc. (LDP) and market appreciation of $696 million.

2014 Compared with 2013

Revenue

Revenue increased 5% to $313.9 million for the year ended December 31, 2014 from $297.7 million for the year ended December 31, 2013. This increase was primarily attributable to higher investment advisory and administration fees resulting from higher average assets under management, partially offset by lower portfolio consulting and other revenue attributable to lower average assets under advisement from model-based strategies. Investment advisory and administration fees increased 8% to $291.7 million for the year ended December 31, 2014, compared with $271.1 million for the year ended December 31, 2013.

For the year ended December 31, 2014, total investment advisory and administration revenue from institutional accounts increased 0.1% to $81.9 million from $81.8 million for the year ended December 31, 2013. The increase in institutional account revenue was attributable to higher average assets under management.

18

For the year ended December 31, 2014, total investment advisory and administration revenue from open-end mutual funds increased 11% to $127.4 million from $114.7 million for the year ended December 31, 2013. The increase in open-end mutual fund revenue was attributable to higher average assets under management.

For the year ended December 31, 2014, total investment advisory and administration revenue from closed-end funds increased 10% to $82.5 million from $74.6 million for the year ended December 31, 2013. The increase in closed-end fund revenue was attributable to higher average assets under management.

Distribution and service fee revenue increased 2% to $14.7 million for the year ended December 31, 2014 from $14.4 million for the year ended December 31, 2013. This increase was primarily due to higher average assets under management in our open-end load mutual funds in 2014.

Portfolio consulting and other revenue decreased 39% to $7.5 million for the year ended December 31, 2014 from $12.2 million for the year ended December 31, 2013.The decrease was primarily attributable to lower average assets under advisement from model-based strategies.

Expenses

Total operating expenses increased 0.3% to $192.0 million for the year ended December 31, 2014 from $191.4 million for the year ended December 31, 2013, primarily due to increases in employee compensation and benefits of $8.0 million and general and administrative expenses of $535,000, partially offset by decreases of $5.8 million in distribution and service fees, $1.2 million in amortization of deferred commissions and $982,000 in depreciation and amortization expenses.

Employee compensation and benefits increased 8% to $102.7 million for the year ended December 31, 2014 from $94.7 million for the year ended December 31, 2013. This increase was primarily due to higher amortization of restricted stock units of approximately $4.0 million and higher incentive compensation of approximately $3.6 million.

General and administrative expenses increased 1% to $47.3 million for the year ended December 31, 2014 from $46.8 million for the year ended December 31, 2013. The increase was primarily due to higher travel and entertainment expenses of approximately $649,000 resulting from increases in hosted conference expenses.

Distribution and service fee expenses decreased 14% to $35.5 million for the year ended December 31, 2014 from $41.2 million for the year ended December 31, 2013. The change, after excluding additional expenses in 2013 of $7.2 million associated with the launch of MIE, was primarily due to an increase in average assets under management in open-end mutual funds.

Non-operating Income

Non-operating income for the year ended December 31, 2014 was $73,000, an increase of $2.1 million from a loss of $2.0 million for the year ended December 31, 2013, primarily due to smaller realized and unrealized losses from seed investments. The non-operating income included net income attributable to redeemable noncontrolling interest of $224,000 for the year ended December 31, 2014 and net loss attributable to redeemable noncontrolling interest of $4.9 million for the year ended December 31, 2013.

Income Taxes

Income tax expense was $46.3 million for the year ended December 31, 2014, compared with $41.1 million for the year ended December 31, 2013. The provision for income taxes for the year ended December 31, 2014 included U.S. federal, state, local and foreign taxes at an effective tax rate of 38%. The effective tax rate for the year ended December 31, 2013 was approximately 37.6%, which included discrete items, the most significant of which was attributable to the launch costs for MIE. Excluding the discrete items, the effective tax rate for the year ended December 31, 2013 was approximately 38%.

2013 Compared with 2012

Revenue

Revenue increased 9% to $297.7 million for the year ended December 31, 2013 from $273.6 million for the year ended December 31, 2012. This increase was primarily attributable to higher investment advisory and administration fees resulting from higher average assets under management, partially offset by lower portfolio consulting and other revenue attributable to lower average assets under advisement from model-based strategies. Investment advisory and administration fees increased

19

11% to $271.1 million for the year ended December 31, 2013, compared with $244.5 million for the year ended December 31, 2012.

For the year ended December 31, 2013, total investment advisory and administration revenue from institutional accounts decreased 8% to $81.8 million from $88.6 million for the year ended December 31, 2012. The decrease in institutional account revenue was attributable to a lower average assets under management.

For the year ended December 31, 2013, total investment advisory and administration revenue from open-end mutual funds increased 19% to $114.7 million from $96.3 million for the year ended December 31, 2012. The increase in open-end mutual fund revenue was attributable to higher average assets under management.

For the year ended December 31, 2013, total investment advisory and administration revenue from closed-end funds increased 25% to $74.6 million from $59.7 million for the year ended December 31, 2012. The increase in closed-end fund revenue was attributable to higher average assets under management primarily from the launch of MIE.

Distribution and service fee revenue increased 27% to $14.4 million for the year ended December 31, 2013 from $11.3 million for the year ended December 31, 2012. This increase was primarily due to higher average assets under management in our open-end mutual funds in 2013.

Portfolio consulting and other revenue decreased 31% to $12.2 million for the year ended December 31, 2013 from $17.7 million for the year ended December 31, 2012. The decrease was primarily attributable to lower average assets under advisement from model-based strategies.

Expenses

Total operating expenses increased 8% to $191.4 million for the year ended December 31, 2013 from $177.1 million for the year ended December 31, 2012, primarily due to increases in general and administrative expenses of $7.4 million and employee compensation and benefits of $6.2 million.

General and administrative expenses increased 19% to $46.8 million for the year ended December 31, 2013 from $39.4 million for the year ended December 31, 2012. The increase was primarily due to higher fund related expenses of approximately $3.1 million, higher rent of approximately $1.5 million resulting from the extension of the lease for our corporate headquarters in New York City, higher professional fees of approximately $1.0 million and higher information technology costs of approximately $736,000, primarily related to upgrades made to our infrastructure, including trading and application systems.

Employee compensation and benefits increased 7% to $94.7 million for the year ended December 31, 2013 from $88.5 million for the year ended December 31, 2012. This increase was primarily due to higher amortization of restricted stock units of approximately $3.8 million and higher salaries of approximately $1.8 million.

Distribution and service fee expenses were $41.2 million for the year ended December 31, 2013, compared with $41.3 million for the year ended December 31, 2012. The 2013 results included approximately $7.2 million of distribution costs associated with the launch of MIE. After adjusting for these costs, distribution and service fee expenses would have been $34.1 million for the year ended December 31, 2013. The 2012 results included approximately $14.4 million of distribution costs associated with the launch of LDP. After adjusting for these costs, distribution and service fee expenses would have been $26.9 million for the year ended December 31, 2012. The increase in distribution and service fee expenses after adjustments was primarily due to higher average assets under management in our open-end mutual funds and additional expenses related to the exercise of the underwriters' over-allotment option for MIE during the year ended December 31, 2013.

Non-operating Income

Non-operating loss for the year ended December 31, 2013 was $2.0 million, a decrease of $9.8 million from income of $7.9 million for the year ended December 31, 2012, primarily due to lower realized and unrealized earnings from seed investments. The non-operating loss included net loss attributable to redeemable noncontrolling interest of $4.9 million for the year ended December 31, 2013 and net income attributable to redeemable noncontrolling interest of $1.8 million for the year ended December 31, 2012.

Income Taxes

Income tax expense was $41.1 million for the year ended December 31, 2013, compared with $36.4 million for the year ended December 31, 2012. The provision for income taxes for the year ended December 31, 2013 included U.S. federal,

20

state, local and foreign taxes at an approximate effective tax rate of 37.6%, which included discrete items, the most significant of which was attributable to the launch costs for MIE. Excluding the discrete items, the effective tax rate for the year ended December 31, 2013 was approximately 38%. The effective tax rate for the year ended December 31, 2012 was approximately 35.5%, which included discrete items, the most significant of which was attributable to the offering costs of LDP. Excluding the discrete items, the effective tax rate for the year ended December 31, 2012 was approximately 36%.

Changes in Financial Condition, Liquidity and Capital Resources

Our investment advisory business does not require us to maintain significant capital balances. Our current financial condition is highly liquid, with a significant amount of our assets comprised of cash and cash equivalents, trading investments, equity method investments, available-for-sale investments and accounts receivable. Our cash flows generally result from the operating activities of our business, with investment advisory and administrative fees being the most significant contributor. Cash and cash equivalents, equity method investments, available-for-sale investments and accounts receivable, excluding investments classified as level 3 in accordance with Accounting Standards Codification (the Codification) Topic 820, Fair Value Measurement (ASC 820), were 78% and 73% of total assets as of December 31, 2014 and 2013, respectively.

Net cash provided by operating activities was $54.6 million for the year ended December 31, 2014, compared with $75.9 million and $20.3 million for the years ended December 31, 2013 and December 31, 2012, respectively. We expect that cash flows provided by operating activities will continue to serve as the principal source of working capital in our near future.

Net cash provided by investing activities was $9.8 million for the year ended December 31, 2014, compared with $18.0 million for the year ended December 31, 2013 and $2.5 million for the year ended December 31, 2012. In 2014, net cash provided by investing activities was primarily comprised of proceeds from sales of available-for-sale investments in the amount of $12.7 million and proceeds from redemption of equity method investments of $10.9 million, partially offset by purchases of available-for-sale investments in the amount of $7.8 million and purchases of property and equipment in the amount of $5.9 million. In 2013, net cash provided by investing activities was primarily comprised of proceeds from sales of available-for-sale investments in the amount of $26.7 million and proceeds from redemption of equity method investments of $7.7 million, partially offset by purchases of available-for-sale investments in the amount of $10.2 million and purchases of property and equipment in the amount of $6.2 million. In 2012, net cash provided by investing activities was primarily comprised of proceeds from sales of available-for-sale investments in the amount of $25.7 million and proceeds from redemption of equity method investments of $811,000, partially offset by purchases of available-for-sale investments in the amount of $20.7 million and purchases of property and equipment in the amount of $3.4 million.

Net cash used in financing activities was $65.6 million for the year ended December 31, 2014, compared with $61.8 million for the year ended December 31, 2013 and $55.7 million for the year ended December 31, 2012. In 2014, net cash used in financing activities was primarily for dividends paid to stockholders of $84.2 million, which included a special dividend of approximately $44.8 million paid on December 19, 2014, repurchases of common stock to satisfy employee withholding tax obligations on the delivery of restricted stock units of $11.7 million and distributions to redeemable noncontrolling interest of $9.0 million, partially offset by contributions from redeemable noncontrolling interest of $36.3 million and excess tax benefits associated with the delivery of restricted stock units of $2.6 million. In 2013, net cash used in financing activities was primarily for dividends paid to stockholders of $79.7 million, which included a special dividend of approximately $44.3 million paid on December 20, 2013, distributions to redeemable noncontrolling interest of $14.2 million and repurchases of common stock to satisfy employee withholding tax obligations on the delivery of restricted stock units of $8.0 million, partially offset by contributions from redeemable noncontrolling interest of $37.7 million and excess tax benefits associated with the delivery of restricted stock units of $2.0 million. In 2012, net cash used in financing activities was primarily for dividends paid to stockholders of $97.2 million, which included a special dividend of approximately $65.6 million paid on December 20, 2012, repurchases of common stock to satisfy employee withholding tax obligations on the delivery of restricted stock units of $8.5 million and distributions to redeemable noncontrolling interest of $8.4 million, partially offset by contributions from redeemable noncontrolling interest of $55.1 million and excess tax benefits associated with delivery of restricted stock units of $2.9 million.

It is our policy to continuously monitor and evaluate the adequacy of our capital. We have consistently maintained net capital in excess of the regulatory requirements for our broker/dealer, as prescribed by the Securities and Exchange Commission (SEC). At December 31, 2014, we exceeded our minimum regulatory capital requirements by approximately $1.3 million. The SEC’s Uniform Net Capital Rule 15c3-1 imposes certain requirements that may have the effect of

21

prohibiting a broker/dealer from distributing or withdrawing capital and requiring prior notice to the SEC for certain withdrawals of capital.

Cohen & Steers Asia Limited (CSAL) and Cohen & Steers UK Limited (CSUK) are regulated outside the U.S. by the Hong Kong Securities and Futures Commission and the United Kingdom Financial Conduct Authority, respectively. At December 31, 2014, CSAL and CSUK exceeded their aggregate minimum regulatory requirements by approximately $56.6 million. We believe that our cash and cash equivalents and cash flows from operations will be more than adequate to meet our anticipated capital requirements and other obligations as they become due.

Included in cash and cash equivalents was approximately $80.1 million held by our foreign subsidiaries as of December 31, 2014. It is our current intention to permanently reinvest funds held by our non-U.S. subsidiaries. We believe that our cash and cash equivalents and short term investments held in the U.S. are more than sufficient to cover our working capital needs in the U.S.

We periodically commit to fund a portion of the equity in certain of our sponsored investment products. We have committed to co-invest up to $5.1 million alongside Cohen & Steers Global Realty Partners III-TE, L.P. (GRP-TE). As of December 31, 2014, we funded approximately $3.2 million with respect to this commitment. Our co-investment alongside GRP-TE is illiquid and is anticipated to be invested for the life of the fund. The timing of the funding of the unfunded portion of our commitment is currently unknown, as the drawdown of our commitment is contingent on the timing of drawdowns by the underlying funds and co-investments in which GRP-TE invests. The unfunded portion of this commitment was not recorded on our consolidated statements of financial condition as of December 31, 2014.

Contractual Obligations and Contingencies

We have contractual obligations to make future payments in connection with our noncancelable operating leases for office space and certain computer and office equipment. There were no material capital lease obligations as of December 31, 2014. The following summarizes our contractual obligations as of December 31, 2014 (in thousands):

	2015		2016		2017		2018		2019		2020 and after		Total
Operating leases	$	11,354	$	11,025	$	10,213	$	9,838	$	10,580	$	42,859	$	95,869

We had $6.3 million, $5.9 million and $4.9 million of total gross unrecognized tax benefits as of December 31, 2014, 2013 and 2012, respectively. The total amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate was $4.1 million, $3.7 million and $3.0 million (net of the federal benefit on state issues) as of December 31, 2014, 2013 and 2012, respectively. We accrue interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of December 31, 2014 and 2013, we had interest and penalties related to unrecognized tax benefits of approximately $1.3 million and $1.2 million, respectively. See Note 14 to the consolidated financial statements for additional disclosures related to income taxes.

Off-Balance Sheet Arrangements

We do not invest in any off-balance sheet vehicles that provide liquidity, capital resources, market or credit risk support, or engage in any leasing activities that expose us to any liability that is not reflected in our consolidated financial statements.

Critical Accounting Policies and Estimates

A thorough understanding of our accounting policies is essential when reviewing our reported results of operations and our financial condition. The preparation of our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Our significant accounting policies are disclosed in Note 2 to the consolidated financial statements and should be read in conjunction with the summarized information below. Management considers the following accounting policies critical to an informed review of our consolidated financial statements as they require management to make certain judgments about matters that may be uncertain at the time the policies were applied or the estimates determined.

22

Consolidation

The Company uses judgment in determining which consolidation model to apply to its investments in affiliated investment companies. The assessment of whether an entity is a variable interest entity (VIE) or voting interest entity (VOE) involves judgment and analysis on an entity by entity basis. In performing this analysis, we consider the legal structure of the entity and the nature of the ownership interest and rights of interest holders in the entity, including the Company. If we determine that the entity is a VIE, we must then assess whether the Company is the primary beneficiary of the VIE. The Company is considered the primary beneficiary of a VIE when it has the obligation to absorb the majority of the expected losses or the right to receive the majority of the expected benefits from the VIE which involves judgment. We consolidate VOEs if we own a majority of the voting interest in the entity.

Investments

Our investments are classified as trading investments, equity method investments or available-for-sale investments at the time of purchase and at the date of each statement of financial condition. The majority of our investments are carried at fair value or amounts that approximate fair value on our statement of financial condition with the periodic mark-to-market included in accumulated other comprehensive income for available-for-sale investments and directly in earnings for trading investments and equity method investments. Fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities reported at fair value are classified and disclosed in a fair value hierarchy based on whether the inputs to the valuation techniques are observable or unobservable. The classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement:

Level 1 - Unadjusted quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices of identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable.

Level 3 - Valuations derived from valuation techniques in which significant inputs or significant value drivers are unobservable.

Goodwill

Goodwill represents the excess of the cost of our investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill is not amortized but is tested annually for impairment and at other times if an event or circumstances occur indicating that it is more likely than not that an impairment has occurred. We estimate the fair value of goodwill using a market approach based upon multiples of AUM and earnings before interest, taxes, depreciation and amortization from a set of comparable peers for the current year and the trailing six years. We determined that the fair value of our goodwill substantially exceeded its carrying value based on the most recent impairment test performed as of November 30, 2014.

Stock-based Compensation

We recognize compensation expense for the grant-date fair value of awards of equity instruments granted to employees. This expense is recognized over the period during which employees are required to provide service and reflects an adjustment for anticipated forfeitures.

Income Taxes

We operate in numerous states and countries through our various subsidiaries and therefore must allocate our income, expenses, and earnings to these taxing jurisdictions taking into account the various laws and regulations in each jurisdiction. Our tax provision represents an estimate of the total liability that we have incurred in these jurisdictions as a result of our operations. Each year we file tax returns in each jurisdiction and settle our return liabilities which may be subject to audit by the taxing authorities. The determination of our annual provision is subject to judgments and estimates and the actual results may vary from the amounts reported in our consolidated financial statements. Accordingly, we recognize additions to, or reductions of, income tax expense during reporting periods that may pertain to prior period provisions as our estimated liabilities are revised and actual tax returns and audits, if any, are settled. Such adjustments are recognized in the discrete quarterly period in which they are determined.

In addition, we record deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for

23

temporary differences that will result in deductible amounts in future years. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years. We record a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

In the normal course of our business, we are exposed to risk as a result of changes in interest and currency rates and securities market and general economic fluctuations, which may have an adverse impact on the value of our investments. At December 31, 2014, we had approximately $9.5 million of trading investments as a result of consolidating Cohen & Steers Active Commodities Strategy Fund, Inc. and Cohen & Steers Co-Investment Partnership, L.P. At December 31, 2014, we had approximately $28.6 million of equity method investments, which represented our equity interests in Cohen & Steers Active Commodities Fund, LP, Cohen & Steers MLP & Energy Opportunity Fund, Inc. and GRP-TE. As of December 31, 2014, we had approximately $21.3 million of available-for-sale investments which were comprised of approximately $5.8 million invested in foreign and domestic common stocks, $1.1 million invested in preferred securities and $14.3 million invested in our sponsored mutual funds.

The following is a summary of the effect that a 10 percent increase or decrease in equity prices would have on our investments subject to equity price fluctuation at December 31, 2014:

	Carrying Value		Carrying Value Assuming a 10% Increase		Carrying Value Assuming a 10% Decrease
Trading investments	$	9,509	$	10,460	$	8,558
Equity method investments	28,550		31,405		25,695
Available-for-sale investments	21,269		23,396		19,142

At December 31, 2014, the Company had outstanding foreign currency forward contracts to hedge its currency exposure related to client receivables with aggregated notional value of approximately $11.1 million. The Company estimates that a 10 percent adverse change in market prices would result in a decrease of approximately $49,000 in the fair value of open foreign currency forward contracts held at December 31, 2014.

A significant majority of our revenue—approximately 93%, 91% and 89% for the years ended December 31, 2014, 2013 and 2012, respectively—was derived from investment advisory agreements with our clients. Under these agreements, the investment advisory and administration fee we receive is based on the market value of the assets we manage. Accordingly, a decline in the prices of securities generally, and real estate securities in particular, attributable to such market factors as inflation, interest rate changes and economic downturn, may cause our revenue and income to decline by:

•causing the value of the assets we manage to decrease, which would result in lower investment advisory and administration fees; or

•causing our clients to withdraw funds in favor of investments that they perceive as offering greater opportunity or lower risk or cost, which would also result in lower investment advisory and administration fees.

In addition, market conditions may preclude us from increasing the assets we manage in closed-end funds. The market conditions for these offerings may not be as favorable in the future, which could adversely impact our ability to grow the assets we manage and realize higher fee revenue associated with such growth. Further, depending on market conditions, the closed-end funds we manage may increase or decrease their leverage in order to maintain the funds' target leverage ratios, thereby increasing or decreasing the assets we manage.

As of December 31, 2014, 53% and 19% of the assets we managed were concentrated in U.S. real estate and global/international real estate strategies, respectively. An increase in interest rates or prolonged economic downturn could have a negative impact on the valuation of real estate securities in our clients' portfolios, which could reduce our revenue. In addition, an increase in interest rates or prolonged economic downturn could negatively impact our ability to increase open-end mutual fund assets and to offer new mutual funds.

We maintain disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Our management, including our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of December 31, 2014. Based on that evaluation and subject to the foregoing, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures as of December 31, 2014 were effective to accomplish their objectives at a reasonable assurance level.

There has been no change in our internal control over financial reporting that occurred during the three months ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

COHEN & STEERS, INC.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Cohen & Steers, Inc. (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company's internal control system is designed to provide reasonable assurance to the Company's management and Board of Directors regarding the reliability of financial reporting and the preparation of published financial statements in accordance with accounting principles generally accepted in the United States of America. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Company's internal control over financial reporting includes (1) policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company; (3) and 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 Company's financial statements.

The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2014. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on its assessment, our management believes that, as of December 31, 2014, the Company's internal control over financial reporting is effective based on those criteria.

The Company's independent registered public accounting firm that audited the accompanying Consolidated Financial Statements has issued an attestation report on the effectiveness of the Company's internal control over financial reporting. Their report appears on the following page.

February 27, 2015

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Cohen & Steers, Inc. New York, NY

We have audited the accompanying consolidated statement of financial condition of Cohen & Steers, Inc. and subsidiaries (the Company) as of December 31, 2014 and 2013, and the related consolidated statements of operations, comprehensive income, changes in stockholders' equity and redeemable noncontrolling interest, and cash flows for each of the three years in the period ended December 31, 2014. We also have audited the Company's internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for these financial statements, 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 these financial statements and an opinion on the Company's internal control over financial reporting 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 and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of Cohen & Steers, Inc. and subsidiaries as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

Cohen & Steers, Inc. (CNS) was organized as a Delaware corporation on March 17, 2004. CNS is the holding company for its direct and indirect subsidiaries, including Cohen & Steers Capital Management, Inc. (CSCM), Cohen & Steers Securities, LLC (CSS), Cohen & Steers Asia Limited, Cohen & Steers UK Limited and Cohen & Steers Japan, LLC (collectively, the Company).

The Company is a leading global investment manager with a long history of innovation and a focus on real assets, including real estate, infrastructure and commodities, along with preferred securities and other income solutions. The Company serves institutional and individual investors around the world. Its clients include Company-sponsored open-end mutual funds and closed-end funds, U.S. and non-U.S. pension plans, endowment funds, foundations and subadvised funds for other financial institutions. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The consolidated financial statements set forth herein include the accounts of CNS and its direct and indirect subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.

2. Summary of Significant Accounting Policies

Accounting Estimates—The preparation of the consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.

Reclassifications—Certain prior year amounts have been reclassified to conform to the current year presentation.

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The Company also consolidates any variable interest entities (VIEs) in which the Company is the primary beneficiary. The Company records noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent. The equity method of accounting is used for investments in affiliates in which the Company’s ownership ranges from 20 to 50 percent, or in instances in which the Company is able to exercise significant influence but not control.

A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns. Investments and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. The Company assesses whether entities in which it has an interest are VIEs upon initial involvement and at each reporting date. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. See Note 4 for further discussion about the Company’s investments.

Cash and Cash Equivalents—Cash equivalents consist of short-term, highly liquid investments, which are readily convertible into cash and have original maturities of three months or less.

Due from Broker—The Company conducts business, primarily through its consolidated seed investments, with brokers for certain of its investment activities. The clearing and custody operations for these investment activities are performed pursuant to agreements with prime brokers. The due from broker balance represents cash and cash equivalents balances at brokers and net receivables and payables for unsettled security transactions.

Investments—Management of the Company determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination at each statement of financial condition date.

F-10

COHEN & STEERS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Investments classified as trading represent securities held within the affiliated funds that the Company consolidates and are measured at fair value based on quoted market prices, market prices obtained from independent pricing services engaged by management or as determined by the Company’s valuation committee. Unrealized gains and losses are recorded as gain (loss) from trading investments—net in the Company’s consolidated statements of operations.

Investments classified as equity method investments are accounted for using the equity method, under which the Company recognizes its respective share of the investee’s net income or loss for the period. As of December 31, 2014, the Company's equity method investments consisted of interests in affiliated funds which measure their underlying investments at fair value and report a net asset value on a recurring basis. The carrying amounts of these investments approximate their fair value.

Investments classified as available-for-sale are comprised of equity securities, investment-grade preferred instruments and investments in Company-sponsored open-end mutual funds. These investments are carried at fair value based on quoted market prices or market prices obtained from independent pricing services engaged by management, with unrealized gains and losses, net of tax, reported in accumulated other comprehensive income. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other than temporary. If the Company believes an impairment of a security position is other than temporary, the loss will be recognized in the Company’s consolidated statements of operations. An other than temporary impairment is presumed to have occurred if the available-for-sale investment has an unrealized loss continuously for 12 or more months.

From time to time, the affiliated funds consolidated by the Company enter into derivative contracts to gain exposure to the underlying commodities markets or to hedge market and credit risks of the underlying portfolios utilizing options, total return swaps, credit default swaps and futures contracts. These instruments are measured at fair value with gains and losses recorded as gain (loss) from trading investments—net in the Company's consolidated statements of operations. The fair values of these instruments are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition. As of December 31, 2014, none of the outstanding derivative contracts were subject to a master netting agreement or other similar arrangement.

Additionally, from time to time, the Company enters into foreign exchange contracts to hedge its currency exposure related to client receivables. These instruments are measured at fair value with gains and losses recorded in other non-operating income in the Company's consolidated statements of operations. The fair values of these contracts are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition.

Goodwill and Intangible Assets—Goodwill represents the excess of the cost of the Company’s investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill and indefinite lived intangible assets are not amortized but are tested at least annually for impairment by comparing the fair value to their carrying amounts. Finite lived intangible assets are amortized over their useful lives and are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. See Note 3 for further discussion about the Company’s goodwill and intangible assets.

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party interests in the Company's consolidated entities. This interest is redeemable at the option of the investors and therefore is not treated as permanent equity. Redeemable noncontrolling interest is remeasured at redemption value which approximates the fair value at each reporting period.

Investment Advisory and Administration Fees—The Company earns revenue by providing asset management services to institutional accounts and to Company-sponsored open-end mutual funds and closed-end funds. Investment advisory fees are earned pursuant to the terms of underlying advisory contracts, and are based on a contractual fee rate applied to the assets in the portfolio, net of applicable waivers, if any. The Company also earns administration fees from certain Company-sponsored open-end mutual funds and closed-end funds pursuant to the terms of underlying administration contracts. Administration fees are based on the average assets under management of such funds. Investment advisory and administration fees revenue is recognized as such fees are earned.

Distribution and Service Fee Revenue—CSS acts as the principal distributor of the Company’s sponsored open-end mutual funds which may offer the following classes: Class A (initial sales load), Class C (back end sales load), Class R (load retirement) and Class Z (no load retirement). Effective May 2007, the Company suspended sales of Class B shares and all remaining Class B shares are expected to convert to Class A shares in 2015. Distribution and service fee revenue is based on the average daily net assets of the funds as detailed below. Distribution and service fee revenue is earned daily and is recorded gross of any third-party distribution and service fee expense for applicable share classes.

Pursuant to distribution plans with the Company's sponsored open-end mutual funds, CSS receives distribution fees of 25bps for Class A shares, 75bps for Class C shares and 50bps for Class R shares. CSS also receives shareholder servicing fees of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares, pursuant to shareholder servicing plans with the funds. Effective October 1, 2014, Class Z shares no longer accrued shareholder servicing fees.

Distribution and Service Fee Expense—Distribution and service fee expense includes distribution fees, service fees and intermediary assistance payments. Distribution and service fee expense is recorded as incurred.

Distribution fee expense represents payments made to qualified dealers/institutions for (i) assistance in connection with the distribution of the Company's sponsored open-end mutual funds' shares and (ii) for other expenses such as advertising costs and printing and distribution of prospectuses to investors. Such amounts may also be used to pay financial intermediaries for services as specified in the terms of written agreements complying with Rule 12b-1 of the Investment Company Act of 1940 (Rule 12b-1). CSS pays distribution fee expense based on the average daily net assets under management of 25bps on Class A shares, 75bps on Class C shares and 50bps on Class R shares.

Shareholder servicing fee expense represents payments made to qualified dealers/institutions for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. CSS pays service fee expenses based on the average daily net assets under management of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares. Effective October 1, 2014, Class Z shares no longer paid shareholder service fees.

Intermediary assistance payments represent payments to qualified dealers/institutions for activities related to distribution, shareholder servicing and marketing and support of Company-sponsored open-end mutual funds and are incremental to those described above. Intermediary assistance payments may be based on the average assets under management, the number of accounts being serviced, or a combination thereof.

During the first quarter of 2013 and the third quarter of 2012, the Company made payments of approximately $7.2 million and $14.4 million, respectively, associated with additional compensation agreements entered into in connection with the offering of two closed-end funds. These payments are included in distribution and service fee expense on the accompanying consolidated statements of operations for the years ended December 31, 2013 and December 31, 2012.

Portfolio Consulting and Other—The Company earns portfolio consulting and other fees by: i) providing portfolio consulting services in connection with model-based strategies accounts; ii) earning a licensing fee for the use of the Company's proprietary indices; and iii) providing portfolio monitoring services related to a number of unit investment trusts. This revenue is earned pursuant to the terms of the underlying contract, and the fee schedules for these relationships vary based on the type of services the Company provides for each relationship. This revenue is recognized as such fees are earned.

Stock-based Compensation—The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments granted to employees. This expense is recognized over the period during which employees are required to provide service. The Company also estimates forfeitures.

Income Taxes—The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years at tax rates that are expected to apply in those years. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

COHEN & STEERS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. Gains or losses resulting from non-U.S. dollar currency transactions are included in other non-operating income in the consolidated statements of operations. The cumulative translation adjustment was $(1,446,000), $2,264,000 and $985,000 as of December 31, 2014, December 31, 2013 and December 31, 2012, respectively.

Comprehensive Income—The Company reports all changes in comprehensive income in the consolidated statements of comprehensive income. Comprehensive income includes net income or loss attributable to common stockholders, foreign currency translation gain and loss (net of tax), unrealized gain and loss from available-for-sale investments (net of tax) and reclassification to statements of operations of gain and loss from available-for-sale investments (net of tax).

Recently Issued Accounting Pronouncements—In February 2015, the Financial Accounting Standards Board (FASB) issued new guidance amending the current accounting for consolidation of certain legal entities. These amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminate the presumption that a general partner should consolidate a limited partnership, affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, and provide a scope exception from consolidation guidance for reporting entities with interests in certain investment funds. This new guidance will be effective for the Company’s first quarter of 2016. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures.

In August 2014, the FASB issued new guidance regarding disclosure of going concern uncertainties in the financial statements. The guidance requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued at each annual and interim reporting period. This new guidance will be effective for the Company’s first quarter of 2017. The Company does not anticipate that the adoption of this new guidance will have a material impact on the Company's consolidated financial statements.

In May 2014, the FASB issued new guidance which outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for the Company's first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption. Early application is prohibited. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures, as well as the available transition methods.

In July 2013, the FASB issued new guidance on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryfoward exists. An entity is required to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward unless a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available as of the reporting date or the entity does not intend to use the deferred tax asset for this purpose (provided that the tax law permits a choice). This new guidance was effective for the Company's first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

In June 2013, the FASB issued new guidance which clarifies the characteristics of an investment company and provides guidance for assessing whether an entity is an investment company. From time to time the Company consolidates certain of its affiliated funds which are considered investment companies. The Company retains the specialized investment company accounting for such funds in consolidation. This new guidance was effective for the Company’s first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

Trading and equity method investments

The Cohen & Steers Active Commodities Strategy Fund, Inc. (CDF), which was launched by the Company in May 2014, is an open-end mutual fund for which the Company is the investment adviser. As of December 31, 2014, the Company owned the majority of the outstanding voting interest in CDF. Accordingly, the underlying assets and liabilities and results of operations of CDF have been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest.

The Cohen & Steers MLP & Energy Opportunity Fund, Inc. (MLO), which was launched by the Company in December 2013, is an open-end mutual fund for which the Company is the investment adviser. The Company owned the majority of the outstanding voting interest in MLO through October 31, 2014. Accordingly, the underlying assets and liabilities and results of operations of MLO had been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest. As a result of additional third-party subscriptions into the fund, effective November 1, 2014, the Company no longer owned the majority of the outstanding voting interest in MLO, however it was determined that the Company had significant influence over MLO. Accordingly, effective November 1, 2014, the Company began recording its investment in MLO using the equity method of accounting.

The Cohen & Steers Active Commodities Fund, LP (ACOM), launched by the Company in April 2013, is structured as a partnership. The Company is the investment adviser of ACOM for which it is entitled to receive a management fee. The Company owned all of the voting interest in ACOM through September 30, 2014. Accordingly, the underlying assets and liabilities and results of operations of ACOM had been included in the Company's consolidated financial statements. As a result of third-party investments into the fund, effective October 1, 2014, the Company no longer held a controlling financial interest in ACOM. The Company determined that ACOM was not a VIE as the limited partners, unaffiliated with the Company, have the ability to liquidate the fund with a majority vote. As a result, the Company does not have financial control and ACOM is not consolidated into the Company's consolidated financial statements. As the general partner, the Company has significant influence over the financial decisions of ACOM and therefore records its investment in ACOM using the

equity method of accounting. The Company's equity interest in ACOM represents a seed investment to launch the fund, adjusted for the Company's proportionate share of the fund's earnings.

Cohen & Steers Global Realty Partners III-TE, L.P. (GRP-TE), which had its closing in October 2011, is structured as a partnership. The Company is the general partner and investment adviser of GRP-TE, for which it receives a management fee and is entitled to receive an incentive distribution, if earned. GRP-TE is a VIE and the Company is not the primary beneficiary. As the general partner, the Company has significant influence over the financial decisions of GRP-TE and therefore records its investment using the equity method of accounting. The Company's equity interest in GRP-TE represents a seed investment to launch the fund, adjusted for the Company’s proportionate share of the fund’s earnings. The Company's risk with respect to its investment in GRP-TE is limited to its equity ownership and any uncollected management fees. In conjunction with the launch of GRP-TE, the Company established Cohen & Steers Co-Investment Partnership, L.P. (GRP-CIP), which is used by the Company to fulfill its contractual commitment to co-invest with GRP-TE. See Note 13 for further discussion regarding the Company's co-investment commitment. As of December 31, 2014, the Company owned all of the voting interest in GRP-CIP. Accordingly, the underlying assets and liabilities and results of operations of GRP-CIP have been included in the Company's consolidated financial statements.

Cohen & Steers Real Assets Fund, Inc. (RAP), which was launched by the Company on January 31, 2012, is an open-end mutual fund for which the Company is the investment adviser. The Company had a controlling financial interest in RAP through July 31, 2013 and therefore, the underlying assets and liabilities and results of operations of RAP had been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest. During the period of August 1, 2013 through September 30, 2014, as a result of additional third-party subscriptions into the fund, the Company no longer held a controlling financial interest in RAP, however it was determined that the Company had significant influence over RAP. Accordingly, the Company recorded its investment in RAP using the equity method of accounting. Effective September 30, 2014, the Company's ownership interest in RAP fell below 20% and the Company no longer has significant influence over RAP. Accordingly, the Company began recording its investment in RAP as available-for-sale investments.

Prior to its liquidation in April 2014, the Company owned the majority of the voting interests in Cohen & Steers Global Real Estate Long-Short Fund, L.P. (the Onshore Fund). Accordingly, the underlying assets and liabilities and results of operations of the Onshore Fund had been included in the Company's consolidated financial statements. The Onshore Fund was structured as a partnership and the Company was the general partner and investment adviser of the fund.

The Cohen & Steers Global Real Estate Long-Short Offshore Fund, L.P. (the Offshore Fund), which was liquidated in April 2014, was structured as a partnership. The Company was the general partner and investment adviser of the Offshore Fund for which it received a management fee and was entitled to receive a performance fee, if earned. The Company determined that the Offshore Fund was not a VIE as the limited partners, unaffiliated with the Company, had the ability to dissolve the fund with a majority vote. As a result, the Company did not have financial control and the Offshore Fund was not consolidated into the Company's consolidated financial statements. As the general partner, the Company had significant influence over the financial decisions of the Offshore Fund and therefore recorded its investment in this fund using the equity method of accounting. The Company’s equity interest in the Offshore Fund represented a seed investment to launch the fund, adjusted for the Company’s proportionate share of the fund’s earnings.

(1)    At December 31, 2013, there were no securities with unrealized losses continuously for a period of more than 12 months.

The aggregate fair value of available-for-sale investments in an unrealized loss position was approximately $15,875,000 and $1,785,000 at December 31, 2014 and December 31, 2013, respectively.

Unrealized losses on available-for-sale investments as of December 31, 2014 were generally caused by market conditions. When evaluating whether an unrealized loss on an available-for-sale investment is other than temporary, the Company reviews such factors as the extent and duration of the loss, deterioration in the issuer’s credit quality, reduction or cessation of dividend payments and overall financial strength of the issuer. As of December 31, 2014, the Company determined that it had the ability and intent to hold the remaining investments for which no other-than-temporary impairment has occurred until a recovery of fair value. Accordingly, impairment of these investments is considered temporary.

5. Fair Value

Codification Topic 820, Fair Value Measurement (ASC 820) specifies a hierarchy of valuation classifications based on whether the inputs to the valuation techniques used in each valuation classification are observable or unobservable. These classifications are summarized in the three broad levels listed below:

• Level 1—Unadjusted quoted prices for identical instruments in active markets.

• Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable.

• Level 3—Valuations derived from valuation techniques in which significant inputs or significant value drivers are unobservable.

Inputs used to measure fair value might fall in different levels of the fair value hierarchy, in which case the Company defaults to the lowest level input that is significant to the fair value measurement in its entirety. These levels are not necessarily an indication of the risk or liquidity associated with the investments. In determining the appropriate levels, the Company performed a detailed analysis of the assets and liabilities that are subject to ASC 820. Transfers among levels, if any, are recorded at the beginning of the reporting period. There were no transfers between level 1 and level 2 during the year ended ended December 31, 2014.

(1) Comprised of investments in actively traded money market funds measured at net asset value.

Trading investments classified as level 2 in the above table were primarily comprised of investments in United States Treasury Bills carried at amortized cost, which approximates fair value.

Trading investments classified as level 3 in the above table were comprised of investments in the common stock of a privately held bank holding company and limited partnership interests. The investments in the common stock of a privately held bank holding company were valued by the Company's valuation committee using a market approach which utilized market multiples derived from a set of comparable public companies. The limited partnership interests represent the Company's co-investments through GRP-CIP. The methodology used to value the investments held by GRP-CIP was changed during the year ended December 31, 2013 as the transaction cost was no longer a reasonable approximation of value due to the passage of time.

Equity method investments classified as level 3 in the above table represent the carrying amount of partnership interests in the Offshore Fund and GRP-TE, which approximate their fair value based on each fund's net asset value. The Offshore Fund made long and short investments in listed real estate equity securities to maximize absolute and risk-adjusted returns with modest volatility. As of December 31, 2013, the Company did not have the ability to redeem its investment in either fund.

Available-for-sale investments classified as level 3 in the above table were comprised of an auction rate preferred security of a closed-end fund which was measured at fair value using a third-party pricing service which utilized a combination of a market approach based on the quoted prices for identical or similar instruments in markets that are not active and an income approach in which the expected cash flows of the securities were discounted back to the measurement date. The Company reviewed the fair value provided by the pricing service and confirmed its understanding of the methodology utilized.

Valuation Techniques

In certain instances, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable brokers/dealers or pricing services. In determining the value of a particular investment, pricing services may use information with respect to transactions in such investments, broker quotes, pricing matrices, market transactions in comparable investments and various relationships between investments. As part of its independent price verification process, the Company selectively performs detailed reviews of valuations provided by broker/dealers or pricing services.

Foreign exchange contracts are valued by interpolating a value using the spot foreign exchange rate and forward points (based on the spot rate and currency interest rate differentials), which are all inputs that are observable in active markets (level 2).

In the absence of observable market prices, the Company values its investments using valuation methodologies applied on a consistent basis. For some investments, little market activity may exist; management's determination of fair value is then based on the best information available in the circumstances, and may incorporate management's own assumptions and involves a significant degree of judgment, taking into consideration a combination of internal and external factors. Such

F-22

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

investments are valued on a quarterly basis, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The valuation process also includes a review by the Company's valuation committee which is comprised of senior members from various departments within the Company, including investment management. The valuation committee provides independent oversight of the valuation policies and procedures.

The valuation techniques and significant unobservable inputs used in the fair value measurement of the following level 3 investments as of December 31, 2014 were:

	Fair Value		Fair Value	Significant	Input /
	(in thousands)		Methodology	Unobservable Inputs	Range
Limited partnership interests - direct investments in real estate	$	1,465	Discounted cash flows	Discount rate Exit capitalization rates Market rental rates	9% - 15% 8% - 8.5% $15.00 - 17.00 psf

The valuation techniques and significant unobservable inputs used in the fair value measurement of the following level 3 investments as of December 31, 2013 were:

	Fair Value		Fair Value	Significant	Input /

Changes in the significant unobservable inputs in the tables above may result in a materially higher or lower fair value measurement. The disclosure in the above tables excludes the Company's ownership interests in limited partnership vehicles which are valued based on the net asset values of the underlying funds. The disclosure in the above table as of December 31, 2013 also excludes auction rate preferred securities for which fair value is based on unobservable but non-quantitative inputs.

8. Earnings Per Share

Basic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share is calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards. Common stock equivalents are excluded from the computation if their effect is anti-dilutive. Diluted earnings per share are computed using the treasury stock method.

No anti-dilutive common stock equivalents were excluded from the computation for the years ended December 31, 2014, 2013 and 2012.

9. Stock-Based Compensation

Amended and Restated Stock Incentive Plan

The Amended and Restated Cohen & Steers, Inc. Stock Incentive Plan (the SIP) provides for the issuance of Restricted Stock Units (RSUs), stock options and other stock-based awards for a period of up to ten years to eligible employees and directors. A total of 16.0 million shares of common stock may be granted under the SIP. At December 31, 2014, RSUs with respect to approximately 12.7 million shares of common stock were issued. Total compensation cost related to unvested RSUs not yet recognized was approximately $34,343,000 at December 31, 2014 and is expected to be recognized over approximately the next three years.

Restricted Stock Units

Vested Restricted Stock Unit Grants

The Company has granted awards of vested RSUs to the independent directors of the Company pursuant to the SIP. The directors are entitled to receive delivery of the underlying common stock on the third anniversary of the date of the grant. Dividends declared during the delayed delivery period are paid to the directors in cash. From time to time, the Company grants awards of vested RSUs to certain employees pursuant to the SIP. These grants are usually delivered pro-rata over four years. At December 31, 2014, vested RSUs with respect to approximately 28,000 shares of common stock were outstanding pursuant to these grants. In connection with the grant of these vested RSUs, the Company recorded non-cash stock-based compensation expense of approximately $352,000, $300,000 and $326,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

The following table sets forth activity relating to the Company's granted awards of vested RSUs under the SIP for awards to the independent directors and certain employees (share data in thousands):

Unvested Restricted Stock Unit Grants

The Company grants awards of unvested RSUs to certain employees pursuant to the SIP. The fair value at the date of grant is expensed on a straight-line basis over the applicable service periods. Except in circumstances where a dividend is determined to be an extraordinary dividend in the sole discretion of the Company's Compensation Committee (in which case dividend equivalents are accrued on such RSUs in the form of additional unvested RSUs), dividends are not paid to the holders of such unvested RSUs. At December 31, 2014, RSUs with respect to approximately 690,000 shares of common stock were outstanding pursuant to these grants. Amortization expense related to the unearned stock-based compensation, net of forfeitures, was approximately $8,590,000, $8,491,000 and $7,328,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Incentive Bonus Plans for Employees of the Company

The Company has implemented a program for employees which, based upon compensation levels, automatically pays a portion of their year-end bonuses in the form of unvested RSUs (Mandatory Program). Prior to performance year 2013, employees could also elect to defer, on a pre-tax basis, an additional portion of their year-end bonus in the form of vested RSUs (Voluntary Program). These RSUs were issued pursuant to the SIP. Prior to performance year 2013, under both plans, the Company matched a predetermined amount of the employee contribution in the form of unvested RSUs. Dividend equivalents are accrued on the deferred compensation awards and the matches in the form of additional unvested RSUs. The RSUs under the Mandatory Program, including the Company match, will vest and be delivered pro-rata over four years. The dividend equivalents issued under the Mandatory Program vest and will be delivered four years after the date of the associated original grant. The RSUs granted under the Voluntary Program vest immediately at the date of grant and will be delivered three years after the date of grant. The Company match and dividend equivalents under the Voluntary Program vest and will be delivered three years after the date of the original grant. The fair value at the date of grant of the RSUs under the Mandatory Program and the matching under both programs is expensed on a straight-line basis. On May 8, 2012, the Company discontinued the company match on amounts deferred under the Mandatory Program. All historical grants made pursuant to the company match on amounts deferred under the Mandatory Program will continue to vest and be delivered in accordance with the previous schedule. Further, on May 8, 2012, the Company discontinued the Voluntary Program, commencing with performance year 2013. All historical grants made pursuant to the Voluntary Program, as well as the Company match on such grants, will continue to vest and/or be delivered in accordance with the previous schedule. All employees that made an election to voluntarily defer a portion of their 2012 year-end bonus were permitted to defer such optional deferred amount, and received a matching contribution from the company on such optional deferred amount.

As of December 31, 2014, approximately 1,412,000 and 42,000 RSUs under the Mandatory Program and Voluntary Program, respectively, including matching and dividend equivalents, were outstanding. In connection with the grant of the vested RSUs issued under the Voluntary Program, the Company recorded a non-cash stock-based compensation expense, including amortization on the matching component, of approximately $116,000, $113,000, and $577,000 for the years ended December 31, 2014, 2013 and 2012, respectively. Amortization expense, net of forfeitures, related to the unearned stock-based compensation of the Mandatory Program, including the matching component, was approximately $16,178,000, $12,863,000 and $10,069,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Employee Stock Purchase Plan

Pursuant to the Amended and Restated Employee Stock Purchase Plan (ESPP), the Company allows eligible employees, as defined in the ESPP, to purchase common stock at a 15% discount from market value with a maximum of $25,000 in annual aggregate purchases by any one individual. The number of shares of common stock authorized for purchase by eligible employees was 600,000. For the years ended December 31, 2014, 2013 and 2012, approximately 14,000, 13,000 and 16,000 shares, respectively, had been purchased by eligible employees through the ESPP. For the years ended December 31, 2014, 2013 and 2012, the Company recorded a non-cash stock-based compensation expense of approximately $87,000, $72,000 and $76,000, respectively, which represents the discount on the shares issued pursuant to this plan. The ESPP will terminate upon the earliest to occur of the following: (1) termination of the ESPP by the board of directors, or (2) issuance of all of the shares reserved for issuance under the ESPP.

10. 401(k) and Profit-Sharing Plan

The Company sponsors a profit-sharing plan (the Plan) covering all employees who meet certain age and service requirements. Subject to limitations, the Plan permits participants to defer up to 100% of their compensation pursuant to Section 401(k) of the Internal Revenue Code. Employee contributions are matched by the Company at $0.50 per $1.00 deferred. The Plan also allows the Company to make discretionary contributions, which are integrated with the taxable wage base under the Social Security Act. No discretionary contributions were made for the years ended December 31, 2014, 2013 and 2012.

Forfeitures occur when participants terminate employment before becoming entitled to their full benefits under the Plan. Forfeited amounts are used to reduce the Company's contributions to the Plan or to pay Plan expenses. Forfeitures for the years ended December 31, 2014, 2013 and 2012 totaled approximately $83,000, $176,000 and $72,000, respectively.

Matching contributions, net of forfeitures, to the Plan totaled approximately $1,074,000, $1,462,000 and $1,110,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

As of December 31, 2014, the Company has funded approximately $3.2 million with respect to this commitment. The actual timing of the funding of this commitment is currently unknown, as the drawdown of the Company's commitment is contingent on the timing of drawdowns by the underlying funds and co-investments in which GRP-TE invests. The unfunded commitment was not recorded on the Company's consolidated statements of financial condition as of December 31, 2014.

14. Income Taxes

At December 31, 2014, the Company had approximately $6,346,000 of total gross unrecognized tax benefits. Of this total, approximately $4,076,000 (net of the federal benefit on state issues) represents the amount of unrecognized tax benefits that, if recognized, would favorably affect the Company's effective tax rate in future periods. The Company expects to reduce its unrecognized tax benefits by $430,000 within the next twelve months due to the lapse of the statute of limitations on certain positions.

Sublease rental income received for the years ended December 31, 2014, 2013 and 2012 was approximately $70,000, $876,000 and $1,025,000, respectively.

From time to time, the Company is involved in legal matters relating to claims arising in the ordinary course of business. There are currently no such matters pending that the Company believes could have a material adverse effect on its consolidated results of operations, cash flows or financial position.

The Company periodically commits to fund a portion of the equity in certain of its sponsored investment products. The Company has committed to co-invest up to $5.1 million alongside GRP-TE, a portion of which is made through GRP-TE and the reminder of which is made through GRP-CIP for up to 12 years through the life of GRP-TE. As of December 31, 2014, the Company has funded approximately $3.2 million with respect to this commitment. The actual timing of the funding of this commitment is currently unknown, as the drawdown of the Company's commitment is contingent on the timing of drawdowns by the underlying funds and co-investments in which GRP-TE invests. The unfunded commitment was not recorded on the Company's consolidated statements of financial condition as of December 31, 2014.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share is calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards. Common stock equivalents are excluded from the computation if their effect is anti-dilutive. Diluted earnings per share are computed using the treasury stock method.

No anti-dilutive common stock equivalents were excluded from the computation for the years ended December 31, 2014, 2013 and 2012.

The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the years ended December 31, 2014, 2013 and 2012 (in thousands, except per share data):

Stock-Based Compensation

Stock-Based Compensation

Amended and Restated Stock Incentive Plan

The Amended and Restated Cohen & Steers, Inc. Stock Incentive Plan (the SIP) provides for the issuance of Restricted Stock Units (RSUs), stock options and other stock-based awards for a period of up to ten years to eligible employees and directors. A total of 16.0 million shares of common stock may be granted under the SIP. At December 31, 2014, RSUs with respect to approximately 12.7 million shares of common stock were issued. Total compensation cost related to unvested RSUs not yet recognized was approximately $34,343,000 at December 31, 2014 and is expected to be recognized over approximately the next three years.

Restricted Stock Units

Vested Restricted Stock Unit Grants

The Company has granted awards of vested RSUs to the independent directors of the Company pursuant to the SIP. The directors are entitled to receive delivery of the underlying common stock on the third anniversary of the date of the grant. Dividends declared during the delayed delivery period are paid to the directors in cash. From time to time, the Company grants awards of vested RSUs to certain employees pursuant to the SIP. These grants are usually delivered pro-rata over four years. At December 31, 2014, vested RSUs with respect to approximately 28,000 shares of common stock were outstanding pursuant to these grants. In connection with the grant of these vested RSUs, the Company recorded non-cash stock-based compensation expense of approximately $352,000, $300,000 and $326,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

The following table sets forth activity relating to the Company's granted awards of vested RSUs under the SIP for awards to the independent directors and certain employees (share data in thousands):

Unvested Restricted Stock Unit Grants

The Company grants awards of unvested RSUs to certain employees pursuant to the SIP. The fair value at the date of grant is expensed on a straight-line basis over the applicable service periods. Except in circumstances where a dividend is determined to be an extraordinary dividend in the sole discretion of the Company's Compensation Committee (in which case dividend equivalents are accrued on such RSUs in the form of additional unvested RSUs), dividends are not paid to the holders of such unvested RSUs. At December 31, 2014, RSUs with respect to approximately 690,000 shares of common stock were outstanding pursuant to these grants. Amortization expense related to the unearned stock-based compensation, net of forfeitures, was approximately $8,590,000, $8,491,000 and $7,328,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Incentive Bonus Plans for Employees of the Company

The Company has implemented a program for employees which, based upon compensation levels, automatically pays a portion of their year-end bonuses in the form of unvested RSUs (Mandatory Program). Prior to performance year 2013, employees could also elect to defer, on a pre-tax basis, an additional portion of their year-end bonus in the form of vested RSUs (Voluntary Program). These RSUs were issued pursuant to the SIP. Prior to performance year 2013, under both plans, the Company matched a predetermined amount of the employee contribution in the form of unvested RSUs. Dividend equivalents are accrued on the deferred compensation awards and the matches in the form of additional unvested RSUs. The RSUs under the Mandatory Program, including the Company match, will vest and be delivered pro-rata over four years. The dividend equivalents issued under the Mandatory Program vest and will be delivered four years after the date of the associated original grant. The RSUs granted under the Voluntary Program vest immediately at the date of grant and will be delivered three years after the date of grant. The Company match and dividend equivalents under the Voluntary Program vest and will be delivered three years after the date of the original grant. The fair value at the date of grant of the RSUs under the Mandatory Program and the matching under both programs is expensed on a straight-line basis. On May 8, 2012, the Company discontinued the company match on amounts deferred under the Mandatory Program. All historical grants made pursuant to the company match on amounts deferred under the Mandatory Program will continue to vest and be delivered in accordance with the previous schedule. Further, on May 8, 2012, the Company discontinued the Voluntary Program, commencing with performance year 2013. All historical grants made pursuant to the Voluntary Program, as well as the Company match on such grants, will continue to vest and/or be delivered in accordance with the previous schedule. All employees that made an election to voluntarily defer a portion of their 2012 year-end bonus were permitted to defer such optional deferred amount, and received a matching contribution from the company on such optional deferred amount.

As of December 31, 2014, approximately 1,412,000 and 42,000 RSUs under the Mandatory Program and Voluntary Program, respectively, including matching and dividend equivalents, were outstanding. In connection with the grant of the vested RSUs issued under the Voluntary Program, the Company recorded a non-cash stock-based compensation expense, including amortization on the matching component, of approximately $116,000, $113,000, and $577,000 for the years ended December 31, 2014, 2013 and 2012, respectively. Amortization expense, net of forfeitures, related to the unearned stock-based compensation of the Mandatory Program, including the matching component, was approximately $16,178,000, $12,863,000 and $10,069,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Accounting Estimates—The preparation of the consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.

Reclassifications—Certain prior year amounts have been reclassified to conform to the current year presentation.

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The Company also consolidates any variable interest entities (VIEs) in which the Company is the primary beneficiary. The Company records noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent. The equity method of accounting is used for investments in affiliates in which the Company’s ownership ranges from 20 to 50 percent, or in instances in which the Company is able to exercise significant influence but not control.

A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns. Investments and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. The Company assesses whether entities in which it has an interest are VIEs upon initial involvement and at each reporting date. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. See Note 4 for further discussion about the Company’s investments.

Cash and Cash Equivalents—Cash equivalents consist of short-term, highly liquid investments, which are readily convertible into cash and have original maturities of three months or less.

Due from Broker—The Company conducts business, primarily through its consolidated seed investments, with brokers for certain of its investment activities. The clearing and custody operations for these investment activities are performed pursuant to agreements with prime brokers. The due from broker balance represents cash and cash equivalents balances at brokers and net receivables and payables for unsettled security transactions.

Investments—Management of the Company determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination at each statement of financial condition date.

Investments classified as trading represent securities held within the affiliated funds that the Company consolidates and are measured at fair value based on quoted market prices, market prices obtained from independent pricing services engaged by management or as determined by the Company’s valuation committee. Unrealized gains and losses are recorded as gain (loss) from trading investments—net in the Company’s consolidated statements of operations.

Investments classified as equity method investments are accounted for using the equity method, under which the Company recognizes its respective share of the investee’s net income or loss for the period. As of December 31, 2014, the Company's equity method investments consisted of interests in affiliated funds which measure their underlying investments at fair value and report a net asset value on a recurring basis. The carrying amounts of these investments approximate their fair value.

Investments classified as available-for-sale are comprised of equity securities, investment-grade preferred instruments and investments in Company-sponsored open-end mutual funds. These investments are carried at fair value based on quoted market prices or market prices obtained from independent pricing services engaged by management, with unrealized gains and losses, net of tax, reported in accumulated other comprehensive income. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other than temporary. If the Company believes an impairment of a security position is other than temporary, the loss will be recognized in the Company’s consolidated statements of operations. An other than temporary impairment is presumed to have occurred if the available-for-sale investment has an unrealized loss continuously for 12 or more months.

From time to time, the affiliated funds consolidated by the Company enter into derivative contracts to gain exposure to the underlying commodities markets or to hedge market and credit risks of the underlying portfolios utilizing options, total return swaps, credit default swaps and futures contracts. These instruments are measured at fair value with gains and losses recorded as gain (loss) from trading investments—net in the Company's consolidated statements of operations. The fair values of these instruments are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition. As of December 31, 2014, none of the outstanding derivative contracts were subject to a master netting agreement or other similar arrangement.

Additionally, from time to time, the Company enters into foreign exchange contracts to hedge its currency exposure related to client receivables. These instruments are measured at fair value with gains and losses recorded in other non-operating income in the Company's consolidated statements of operations. The fair values of these contracts are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition.

Goodwill and Intangible Assets—Goodwill represents the excess of the cost of the Company’s investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill and indefinite lived intangible assets are not amortized but are tested at least annually for impairment by comparing the fair value to their carrying amounts. Finite lived intangible assets are amortized over their useful lives and are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. See Note 3 for further discussion about the Company’s goodwill and intangible assets.

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party interests in the Company's consolidated entities. This interest is redeemable at the option of the investors and therefore is not treated as permanent equity. Redeemable noncontrolling interest is remeasured at redemption value which approximates the fair value at each reporting period.

Investment Advisory and Administration Fees—The Company earns revenue by providing asset management services to institutional accounts and to Company-sponsored open-end mutual funds and closed-end funds. Investment advisory fees are earned pursuant to the terms of underlying advisory contracts, and are based on a contractual fee rate applied to the assets in the portfolio, net of applicable waivers, if any. The Company also earns administration fees from certain Company-sponsored open-end mutual funds and closed-end funds pursuant to the terms of underlying administration contracts. Administration fees are based on the average assets under management of such funds. Investment advisory and administration fees revenue is recognized as such fees are earned.

Distribution and Service Fee Revenue—CSS acts as the principal distributor of the Company’s sponsored open-end mutual funds which may offer the following classes: Class A (initial sales load), Class C (back end sales load), Class R (load retirement) and Class Z (no load retirement). Effective May 2007, the Company suspended sales of Class B shares and all remaining Class B shares are expected to convert to Class A shares in 2015. Distribution and service fee revenue is based on the average daily net assets of the funds as detailed below. Distribution and service fee revenue is earned daily and is recorded gross of any third-party distribution and service fee expense for applicable share classes.

Pursuant to distribution plans with the Company's sponsored open-end mutual funds, CSS receives distribution fees of 25bps for Class A shares, 75bps for Class C shares and 50bps for Class R shares. CSS also receives shareholder servicing fees of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares, pursuant to shareholder servicing plans with the funds. Effective October 1, 2014, Class Z shares no longer accrued shareholder servicing fees.

Distribution and Service Fee Expense—Distribution and service fee expense includes distribution fees, service fees and intermediary assistance payments. Distribution and service fee expense is recorded as incurred.

Distribution fee expense represents payments made to qualified dealers/institutions for (i) assistance in connection with the distribution of the Company's sponsored open-end mutual funds' shares and (ii) for other expenses such as advertising costs and printing and distribution of prospectuses to investors. Such amounts may also be used to pay financial intermediaries for services as specified in the terms of written agreements complying with Rule 12b-1 of the Investment Company Act of 1940 (Rule 12b-1). CSS pays distribution fee expense based on the average daily net assets under management of 25bps on Class A shares, 75bps on Class C shares and 50bps on Class R shares.

Shareholder servicing fee expense represents payments made to qualified dealers/institutions for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. CSS pays service fee expenses based on the average daily net assets under management of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares. Effective October 1, 2014, Class Z shares no longer paid shareholder service fees.

Intermediary assistance payments represent payments to qualified dealers/institutions for activities related to distribution, shareholder servicing and marketing and support of Company-sponsored open-end mutual funds and are incremental to those described above. Intermediary assistance payments may be based on the average assets under management, the number of accounts being serviced, or a combination thereof.

During the first quarter of 2013 and the third quarter of 2012, the Company made payments of approximately $7.2 million and $14.4 million, respectively, associated with additional compensation agreements entered into in connection with the offering of two closed-end funds. These payments are included in distribution and service fee expense on the accompanying consolidated statements of operations for the years ended December 31, 2013 and December 31, 2012.

Portfolio Consulting and Other—The Company earns portfolio consulting and other fees by: i) providing portfolio consulting services in connection with model-based strategies accounts; ii) earning a licensing fee for the use of the Company's proprietary indices; and iii) providing portfolio monitoring services related to a number of unit investment trusts. This revenue is earned pursuant to the terms of the underlying contract, and the fee schedules for these relationships vary based on the type of services the Company provides for each relationship. This revenue is recognized as such fees are earned.

Stock-based Compensation—The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments granted to employees. This expense is recognized over the period during which employees are required to provide service. The Company also estimates forfeitures.

Income Taxes—The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years at tax rates that are expected to apply in those years. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. Gains or losses resulting from non-U.S. dollar currency transactions are included in other non-operating income in the consolidated statements of operations. The cumulative translation adjustment was $(1,446,000), $2,264,000 and $985,000 as of December 31, 2014, December 31, 2013 and December 31, 2012, respectively.

Comprehensive Income—The Company reports all changes in comprehensive income in the consolidated statements of comprehensive income. Comprehensive income includes net income or loss attributable to common stockholders, foreign currency translation gain and loss (net of tax), unrealized gain and loss from available-for-sale investments (net of tax) and reclassification to statements of operations of gain and loss from available-for-sale investments (net of tax).

Recently Issued Accounting Pronouncements—In February 2015, the Financial Accounting Standards Board (FASB) issued new guidance amending the current accounting for consolidation of certain legal entities. These amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminate the presumption that a general partner should consolidate a limited partnership, affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, and provide a scope exception from consolidation guidance for reporting entities with interests in certain investment funds. This new guidance will be effective for the Company’s first quarter of 2016. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures.

In August 2014, the FASB issued new guidance regarding disclosure of going concern uncertainties in the financial statements. The guidance requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued at each annual and interim reporting period. This new guidance will be effective for the Company’s first quarter of 2017. The Company does not anticipate that the adoption of this new guidance will have a material impact on the Company's consolidated financial statements.

In May 2014, the FASB issued new guidance which outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for the Company's first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption. Early application is prohibited. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures, as well as the available transition methods.

In July 2013, the FASB issued new guidance on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryfoward exists. An entity is required to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward unless a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available as of the reporting date or the entity does not intend to use the deferred tax asset for this purpose (provided that the tax law permits a choice). This new guidance was effective for the Company's first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

In June 2013, the FASB issued new guidance which clarifies the characteristics of an investment company and provides guidance for assessing whether an entity is an investment company. From time to time the Company consolidates certain of its affiliated funds which are considered investment companies. The Company retains the specialized investment company accounting for such funds in consolidation. This new guidance was effective for the Company’s first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

Income Taxes

Income Taxes

The provision for income taxes for the years ended December 31, 2014, 2013 and 2012 includes U.S. federal, state, local and foreign taxes. The effective tax rate for the year ended December 31, 2014 was approximately 38%. The effective tax rate of approximately 37.6% for the year ended December 31, 2013 included discrete items, the most significant of which was attributable to the launch costs for Cohen & Steers MLP Income and Energy Opportunity Fund, Inc., a closed-end fund. Excluding the discrete items, the effective tax rate for the year ended December 31, 2013 was approximately 38%. The effective tax rate of approximately 35.5% for the year ended December 31, 2012 included discrete items, the most significant of which was attributable to the launch costs for Cohen & Steers Limited Duration Preferred and Income Fund, Inc., a closed-end fund. Excluding the discrete items, the effective tax rate for the year ended December 31, 2012 was approximately 36%.

The Company does not provide for deferred taxes on the excess of the financial reporting basis over the tax basis in its investments in foreign subsidiaries that are essentially permanent in duration. That excess totaled approximately $73,425,000 as of December 31, 2014. The determination of the additional deferred taxes that have not been provided is not practicable because of the complexities of the hypothetical calculation.

The income before provision for income taxes and provision for income taxes for the years ended December 31, 2014, 2013 and 2012 are as follows (in thousands):

	Years Ended December 31,

Provision for income taxes	$	46,280		$	41,109		$	36,407

Deferred income taxes represent the tax effects of the temporary differences between book and tax bases and are measured using enacted tax rates that will be in effect when such items are expected to reverse. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Significant components of the Company's net deferred income tax asset at December 31, 2014 and 2013 consist of the following (in thousands):

	At December 31,
	2014			2013
Deferred income tax assets (liabilities):
Stock-based compensation	$	8,923		$	7,953

The Company had capital loss carryforwards of approximately $11,700,000 and $11,300,000 for the years ended December 31, 2014 and December 31, 2013 which, if unused, will expire in years 2015 to 2019. The valuation allowance on the net deferred income tax asset increased approximately $995,000 during the year ended December 31, 2014.

At December 31, 2014, the Company had approximately $6,346,000 of total gross unrecognized tax benefits. Of this total, approximately $4,076,000 (net of the federal benefit on state issues) represents the amount of unrecognized tax benefits that, if recognized, would favorably affect the Company's effective tax rate in future periods. The Company expects to reduce its unrecognized tax benefits by $430,000 within the next twelve months due to the lapse of the statute of limitations on certain positions.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands):

	Liability for Unrecognized Tax Benefits
Gross unrecognized tax benefits balance at January 1, 2012	$	4,712
Addition for tax positions of current year	933
Addition for tax positions of prior years	74

Gross unrecognized tax benefits balance at December 31, 2014	$	6,346

The Company recognizes potential interest and penalties related to uncertain tax positions in the provision for income taxes. At December 31, 2014 and 2013, the Company had approximately $1,267,000 and $1,170,000, respectively, in potential interest and penalties associated with uncertain tax positions.

The tax years 2010 through 2014 remain open to examination by various taxing jurisdictions.

A reconciliation of the Company's statutory federal income tax rate and the effective tax rate for the years ended December 31, 2014, 2013 and 2012 is as follows:

Compensation Related Costs [Abstract]

401 (k) and Profit-Sharing Plan

401(k) and Profit-Sharing Plan

The Company sponsors a profit-sharing plan (the Plan) covering all employees who meet certain age and service requirements. Subject to limitations, the Plan permits participants to defer up to 100% of their compensation pursuant to Section 401(k) of the Internal Revenue Code. Employee contributions are matched by the Company at $0.50 per $1.00 deferred. The Plan also allows the Company to make discretionary contributions, which are integrated with the taxable wage base under the Social Security Act. No discretionary contributions were made for the years ended December 31, 2014, 2013 and 2012.

Forfeitures occur when participants terminate employment before becoming entitled to their full benefits under the Plan. Forfeited amounts are used to reduce the Company's contributions to the Plan or to pay Plan expenses. Forfeitures for the years ended December 31, 2014, 2013 and 2012 totaled approximately $83,000, $176,000 and $72,000, respectively.

Matching contributions, net of forfeitures, to the Plan totaled approximately $1,074,000, $1,462,000 and $1,110,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

Trading and equity method investments

The Cohen & Steers Active Commodities Strategy Fund, Inc. (CDF), which was launched by the Company in May 2014, is an open-end mutual fund for which the Company is the investment adviser. As of December 31, 2014, the Company owned the majority of the outstanding voting interest in CDF. Accordingly, the underlying assets and liabilities and results of operations of CDF have been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest.

The Cohen & Steers MLP & Energy Opportunity Fund, Inc. (MLO), which was launched by the Company in December 2013, is an open-end mutual fund for which the Company is the investment adviser. The Company owned the majority of the outstanding voting interest in MLO through October 31, 2014. Accordingly, the underlying assets and liabilities and results of operations of MLO had been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest. As a result of additional third-party subscriptions into the fund, effective November 1, 2014, the Company no longer owned the majority of the outstanding voting interest in MLO, however it was determined that the Company had significant influence over MLO. Accordingly, effective November 1, 2014, the Company began recording its investment in MLO using the equity method of accounting.

The Cohen & Steers Active Commodities Fund, LP (ACOM), launched by the Company in April 2013, is structured as a partnership. The Company is the investment adviser of ACOM for which it is entitled to receive a management fee. The Company owned all of the voting interest in ACOM through September 30, 2014. Accordingly, the underlying assets and liabilities and results of operations of ACOM had been included in the Company's consolidated financial statements. As a result of third-party investments into the fund, effective October 1, 2014, the Company no longer held a controlling financial interest in ACOM. The Company determined that ACOM was not a VIE as the limited partners, unaffiliated with the Company, have the ability to liquidate the fund with a majority vote. As a result, the Company does not have financial control and ACOM is not consolidated into the Company's consolidated financial statements. As the general partner, the Company has significant influence over the financial decisions of ACOM and therefore records its investment in ACOM using the equity method of accounting. The Company's equity interest in ACOM represents a seed investment to launch the fund, adjusted for the Company's proportionate share of the fund's earnings.

Cohen & Steers Global Realty Partners III-TE, L.P. (GRP-TE), which had its closing in October 2011, is structured as a partnership. The Company is the general partner and investment adviser of GRP-TE, for which it receives a management fee and is entitled to receive an incentive distribution, if earned. GRP-TE is a VIE and the Company is not the primary beneficiary. As the general partner, the Company has significant influence over the financial decisions of GRP-TE and therefore records its investment using the equity method of accounting. The Company's equity interest in GRP-TE represents a seed investment to launch the fund, adjusted for the Company’s proportionate share of the fund’s earnings. The Company's risk with respect to its investment in GRP-TE is limited to its equity ownership and any uncollected management fees. In conjunction with the launch of GRP-TE, the Company established Cohen & Steers Co-Investment Partnership, L.P. (GRP-CIP), which is used by the Company to fulfill its contractual commitment to co-invest with GRP-TE. See Note 13 for further discussion regarding the Company's co-investment commitment. As of December 31, 2014, the Company owned all of the voting interest in GRP-CIP. Accordingly, the underlying assets and liabilities and results of operations of GRP-CIP have been included in the Company's consolidated financial statements.

Cohen & Steers Real Assets Fund, Inc. (RAP), which was launched by the Company on January 31, 2012, is an open-end mutual fund for which the Company is the investment adviser. The Company had a controlling financial interest in RAP through July 31, 2013 and therefore, the underlying assets and liabilities and results of operations of RAP had been included in the Company's consolidated financial statements with the third-party interests classified as redeemable noncontrolling interest. During the period of August 1, 2013 through September 30, 2014, as a result of additional third-party subscriptions into the fund, the Company no longer held a controlling financial interest in RAP, however it was determined that the Company had significant influence over RAP. Accordingly, the Company recorded its investment in RAP using the equity method of accounting. Effective September 30, 2014, the Company's ownership interest in RAP fell below 20% and the Company no longer has significant influence over RAP. Accordingly, the Company began recording its investment in RAP as available-for-sale investments.

Prior to its liquidation in April 2014, the Company owned the majority of the voting interests in Cohen & Steers Global Real Estate Long-Short Fund, L.P. (the Onshore Fund). Accordingly, the underlying assets and liabilities and results of operations of the Onshore Fund had been included in the Company's consolidated financial statements. The Onshore Fund was structured as a partnership and the Company was the general partner and investment adviser of the fund.

The Cohen & Steers Global Real Estate Long-Short Offshore Fund, L.P. (the Offshore Fund), which was liquidated in April 2014, was structured as a partnership. The Company was the general partner and investment adviser of the Offshore Fund for which it received a management fee and was entitled to receive a performance fee, if earned. The Company determined that the Offshore Fund was not a VIE as the limited partners, unaffiliated with the Company, had the ability to dissolve the fund with a majority vote. As a result, the Company did not have financial control and the Offshore Fund was not consolidated into the Company's consolidated financial statements. As the general partner, the Company had significant influence over the financial decisions of the Offshore Fund and therefore recorded its investment in this fund using the equity method of accounting. The Company’s equity interest in the Offshore Fund represented a seed investment to launch the fund, adjusted for the Company’s proportionate share of the fund’s earnings.

(1)    At December 31, 2013, there were no securities with unrealized losses continuously for a period of more than 12 months.

The aggregate fair value of available-for-sale investments in an unrealized loss position was approximately $15,875,000 and $1,785,000 at December 31, 2014 and December 31, 2013, respectively.

Unrealized losses on available-for-sale investments as of December 31, 2014 were generally caused by market conditions. When evaluating whether an unrealized loss on an available-for-sale investment is other than temporary, the Company reviews such factors as the extent and duration of the loss, deterioration in the issuer’s credit quality, reduction or cessation of dividend payments and overall financial strength of the issuer. As of December 31, 2014, the Company determined that it had the ability and intent to hold the remaining investments for which no other-than-temporary impairment has occurred until a recovery of fair value. Accordingly, impairment of these investments is considered temporary.

Fair Value [Abstract]

Fair Value

Fair Value

Codification Topic 820, Fair Value Measurement (ASC 820) specifies a hierarchy of valuation classifications based on whether the inputs to the valuation techniques used in each valuation classification are observable or unobservable. These classifications are summarized in the three broad levels listed below:

• Level 1—Unadjusted quoted prices for identical instruments in active markets.

• Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable.

• Level 3—Valuations derived from valuation techniques in which significant inputs or significant value drivers are unobservable.

Inputs used to measure fair value might fall in different levels of the fair value hierarchy, in which case the Company defaults to the lowest level input that is significant to the fair value measurement in its entirety. These levels are not necessarily an indication of the risk or liquidity associated with the investments. In determining the appropriate levels, the Company performed a detailed analysis of the assets and liabilities that are subject to ASC 820. Transfers among levels, if any, are recorded at the beginning of the reporting period. There were no transfers between level 1 and level 2 during the year ended ended December 31, 2014.

The following table presents fair value measurements as of December 31, 2014 (in thousands):

Trading investments classified as level 2 in the above table were primarily comprised of investments in United States Treasury Bills carried at amortized cost, which approximates fair value.

Trading investments classified as level 3 in the above table were comprised of limited partnership interests which represent the Company's co-investments through GRP-CIP, which along with the Company's interest in GRP-TE, represent the Company's collective ownership interests in limited partnership vehicles that invest in non-registered real estate funds which are valued based on the net asset values of the underlying funds and private equity vehicles that invest directly in real estate which are generally valued using a discounted cash flow model.

Equity method investments classified as level 2 in the above table represent the carrying amount of the Company's partnership interest in ACOM, which approximates its fair value based on the fund's net asset value. ACOM invests in exchange-traded commodity futures contracts and other commodity related derivatives. The Company has the ability to redeem its investment in the fund monthly at net asset value per share with prior written notice of 15 days and there are no significant restrictions to redemption.

Equity method investments classified as level 3 in the above table represent the carrying amount of the Company's partnership interests in GRP-TE, which approximate its fair value based on the fund's net asset value. GRP-TE invests in non-registered real estate funds and in private equity vehicles that invest directly in real estate. As of December 31, 2014, the Company did not have the ability to redeem its investment in GRP-TE.

(1) Comprised of investments in actively traded money market funds measured at net asset value.

Trading investments classified as level 2 in the above table were primarily comprised of investments in United States Treasury Bills carried at amortized cost, which approximates fair value.

Trading investments classified as level 3 in the above table were comprised of investments in the common stock of a privately held bank holding company and limited partnership interests. The investments in the common stock of a privately held bank holding company were valued by the Company's valuation committee using a market approach which utilized market multiples derived from a set of comparable public companies. The limited partnership interests represent the Company's co-investments through GRP-CIP. The methodology used to value the investments held by GRP-CIP was changed during the year ended December 31, 2013 as the transaction cost was no longer a reasonable approximation of value due to the passage of time.

Equity method investments classified as level 3 in the above table represent the carrying amount of partnership interests in the Offshore Fund and GRP-TE, which approximate their fair value based on each fund's net asset value. The Offshore Fund made long and short investments in listed real estate equity securities to maximize absolute and risk-adjusted returns with modest volatility. As of December 31, 2013, the Company did not have the ability to redeem its investment in either fund.

Available-for-sale investments classified as level 3 in the above table were comprised of an auction rate preferred security of a closed-end fund which was measured at fair value using a third-party pricing service which utilized a combination of a market approach based on the quoted prices for identical or similar instruments in markets that are not active and an income approach in which the expected cash flows of the securities were discounted back to the measurement date. The Company reviewed the fair value provided by the pricing service and confirmed its understanding of the methodology utilized.

The following table summarizes the changes in level 3 investments measured at fair value on a recurring basis for the years ended December 31, 2014 and 2013 (in thousands):

	Trading Investments						Equity Method Investments				Available-for-sale investments

(2) Transferred from level 2 to level 3 during the year ended December 31, 2013 due to the imposition of redemption restrictions on the Company's investment in connection with the winding down of the operations of the Offshore Fund.

Realized gains (losses) from investments classified as trading investments, equity method investments and available-for-sale investments in the above table were recorded as gain (loss) from trading investments, equity in earnings (losses) of affiliates and gain (loss) from available-for-sale investments, respectively, in the Company's consolidated statements of operations. Unrealized gains (losses) from investments classified as trading investments and equity method investments in the above table were recorded as gain (loss) from trading investments and equity in earnings (losses) of affiliates, respectively, in the Company's consolidated statements of operations. Unrealized gains (losses) from available-for-sale investments in the above table were recorded as unrealized gain (loss) from available-for-sale investments in the Company's consolidated statements of comprehensive income.

Valuation Techniques

In certain instances, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable brokers/dealers or pricing services. In determining the value of a particular investment, pricing services may use information with respect to transactions in such investments, broker quotes, pricing matrices, market transactions in comparable investments and various relationships between investments. As part of its independent price verification process, the Company selectively performs detailed reviews of valuations provided by broker/dealers or pricing services.

Foreign exchange contracts are valued by interpolating a value using the spot foreign exchange rate and forward points (based on the spot rate and currency interest rate differentials), which are all inputs that are observable in active markets (level 2).

In the absence of observable market prices, the Company values its investments using valuation methodologies applied on a consistent basis. For some investments, little market activity may exist; management's determination of fair value is then based on the best information available in the circumstances, and may incorporate management's own assumptions and involves a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments are valued on a quarterly basis, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The valuation process also includes a review by the Company's valuation committee which is comprised of senior members from various departments within the Company, including investment management. The valuation committee provides independent oversight of the valuation policies and procedures.

The valuation techniques and significant unobservable inputs used in the fair value measurement of the following level 3 investments as of December 31, 2014 were:

	Fair Value		Fair Value	Significant	Input /
	(in thousands)		Methodology	Unobservable Inputs	Range
Limited partnership interests - direct investments in real estate	$	1,465	Discounted cash flows	Discount rate Exit capitalization rates Market rental rates	9% - 15% 8% - 8.5% $15.00 - 17.00 psf

The valuation techniques and significant unobservable inputs used in the fair value measurement of the following level 3 investments as of December 31, 2013 were:

	Fair Value		Fair Value	Significant	Input /
	(in thousands)		Methodology	Unobservable Inputs	Range
Common shares of privately-held company	$	503	Market comparable companies	Price / tangible book ratio Liquidity discount	1.48x 33%
Limited partnership interests - direct investments in real estate	$	2,101	Discounted cash flows	Discount rate Exit capitalization rates Market rental rates	9% - 15% 8.5% - 9% $15.00 - 16.25 psf

Changes in the significant unobservable inputs in the tables above may result in a materially higher or lower fair value measurement. The disclosure in the above tables excludes the Company's ownership interests in limited partnership vehicles which are valued based on the net asset values of the underlying funds. The disclosure in the above table as of December 31, 2013 also excludes auction rate preferred securities for which fair value is based on unobservable but non-quantitative inputs. Such items include financial instruments for which the determination of fair value is based on unadjusted quotations provided by a third-party pricing service.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Accounting Policies [Abstract]

Accounting Estimates

Accounting Estimates—The preparation of the consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.

Reclassifications

Reclassifications—Certain prior year amounts have been reclassified to conform to the current year presentation.

Consolidation

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The Company also consolidates any variable interest entities (VIEs) in which the Company is the primary beneficiary. The Company records noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent. The equity method of accounting is used for investments in affiliates in which the Company’s ownership ranges from 20 to 50 percent, or in instances in which the Company is able to exercise significant influence but not control.

VIE

A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns. Investments and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. The Company assesses whether entities in which it has an interest are VIEs upon initial involvement and at each reporting date. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees.

Cash and Cash Equivalents

Cash and Cash Equivalents—Cash equivalents consist of short-term, highly liquid investments, which are readily convertible into cash and have original maturities of three months or less.

Due from Broker

Due from Broker—The Company conducts business, primarily through its consolidated seed investments, with brokers for certain of its investment activities. The clearing and custody operations for these investment activities are performed pursuant to agreements with prime brokers. The due from broker balance represents cash and cash equivalents balances at brokers and net receivables and payables for unsettled security transactions.

Investments

Investments—Management of the Company determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination at each statement of financial condition date.

Investments classified as trading represent securities held within the affiliated funds that the Company consolidates and are measured at fair value based on quoted market prices, market prices obtained from independent pricing services engaged by management or as determined by the Company’s valuation committee. Unrealized gains and losses are recorded as gain (loss) from trading investments—net in the Company’s consolidated statements of operations.

Investments classified as equity method investments are accounted for using the equity method, under which the Company recognizes its respective share of the investee’s net income or loss for the period. As of December 31, 2014, the Company's equity method investments consisted of interests in affiliated funds which measure their underlying investments at fair value and report a net asset value on a recurring basis. The carrying amounts of these investments approximate their fair value.

Investments classified as available-for-sale are comprised of equity securities, investment-grade preferred instruments and investments in Company-sponsored open-end mutual funds. These investments are carried at fair value based on quoted market prices or market prices obtained from independent pricing services engaged by management, with unrealized gains and losses, net of tax, reported in accumulated other comprehensive income. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other than temporary. If the Company believes an impairment of a security position is other than temporary, the loss will be recognized in the Company’s consolidated statements of operations. An other than temporary impairment is presumed to have occurred if the available-for-sale investment has an unrealized loss continuously for 12 or more months.

From time to time, the affiliated funds consolidated by the Company enter into derivative contracts to gain exposure to the underlying commodities markets or to hedge market and credit risks of the underlying portfolios utilizing options, total return swaps, credit default swaps and futures contracts. These instruments are measured at fair value with gains and losses recorded as gain (loss) from trading investments—net in the Company's consolidated statements of operations. The fair values of these instruments are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition. As of December 31, 2014, none of the outstanding derivative contracts were subject to a master netting agreement or other similar arrangement.

Additionally, from time to time, the Company enters into foreign exchange contracts to hedge its currency exposure related to client receivables. These instruments are measured at fair value with gains and losses recorded in other non-operating income in the Company's consolidated statements of operations. The fair values of these contracts are recorded in other assets or other liabilities and accrued expenses in the Company's consolidated statements of financial condition.

Goodwill and Intangible Assets

Goodwill and Intangible Assets—Goodwill represents the excess of the cost of the Company’s investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill and indefinite lived intangible assets are not amortized but are tested at least annually for impairment by comparing the fair value to their carrying amounts. Finite lived intangible assets are amortized over their useful lives and are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Redeemable Noncontrolling Interest

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party interests in the Company's consolidated entities. This interest is redeemable at the option of the investors and therefore is not treated as permanent equity. Redeemable noncontrolling interest is remeasured at redemption value which approximates the fair value at each reporting period.

Investment Advisory and Administration Fees

Investment Advisory and Administration Fees—The Company earns revenue by providing asset management services to institutional accounts and to Company-sponsored open-end mutual funds and closed-end funds. Investment advisory fees are earned pursuant to the terms of underlying advisory contracts, and are based on a contractual fee rate applied to the assets in the portfolio, net of applicable waivers, if any. The Company also earns administration fees from certain Company-sponsored open-end mutual funds and closed-end funds pursuant to the terms of underlying administration contracts. Administration fees are based on the average assets under management of such funds. Investment advisory and administration fees revenue is recognized as such fees are earned.

Distribution and Service Fee Revenue

Distribution and Service Fee Revenue—CSS acts as the principal distributor of the Company’s sponsored open-end mutual funds which may offer the following classes: Class A (initial sales load), Class C (back end sales load), Class R (load retirement) and Class Z (no load retirement). Effective May 2007, the Company suspended sales of Class B shares and all remaining Class B shares are expected to convert to Class A shares in 2015. Distribution and service fee revenue is based on the average daily net assets of the funds as detailed below. Distribution and service fee revenue is earned daily and is recorded gross of any third-party distribution and service fee expense for applicable share classes.

Pursuant to distribution plans with the Company's sponsored open-end mutual funds, CSS receives distribution fees of 25bps for Class A shares, 75bps for Class C shares and 50bps for Class R shares. CSS also receives shareholder servicing fees of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares, pursuant to shareholder servicing plans with the funds. Effective October 1, 2014, Class Z shares no longer accrued shareholder servicing fees.

Distribution and Service Fee Expense

Distribution and Service Fee Expense—Distribution and service fee expense includes distribution fees, service fees and intermediary assistance payments. Distribution and service fee expense is recorded as incurred.

Distribution fee expense represents payments made to qualified dealers/institutions for (i) assistance in connection with the distribution of the Company's sponsored open-end mutual funds' shares and (ii) for other expenses such as advertising costs and printing and distribution of prospectuses to investors. Such amounts may also be used to pay financial intermediaries for services as specified in the terms of written agreements complying with Rule 12b-1 of the Investment Company Act of 1940 (Rule 12b-1). CSS pays distribution fee expense based on the average daily net assets under management of 25bps on Class A shares, 75bps on Class C shares and 50bps on Class R shares.

Shareholder servicing fee expense represents payments made to qualified dealers/institutions for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. CSS pays service fee expenses based on the average daily net assets under management of 10bps on Class A shares, 25bps on Class C shares and 15bps on Class Z shares. Effective October 1, 2014, Class Z shares no longer paid shareholder service fees.

Intermediary assistance payments represent payments to qualified dealers/institutions for activities related to distribution, shareholder servicing and marketing and support of Company-sponsored open-end mutual funds and are incremental to those described above. Intermediary assistance payments may be based on the average assets under management, the number of accounts being serviced, or a combination thereof.

Portfolio Consulting and Other

Portfolio Consulting and Other—The Company earns portfolio consulting and other fees by: i) providing portfolio consulting services in connection with model-based strategies accounts; ii) earning a licensing fee for the use of the Company's proprietary indices; and iii) providing portfolio monitoring services related to a number of unit investment trusts. This revenue is earned pursuant to the terms of the underlying contract, and the fee schedules for these relationships vary based on the type of services the Company provides for each relationship. This revenue is recognized as such fees are earned.

Stock-based Compensation

Stock-based Compensation—The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments granted to employees. This expense is recognized over the period during which employees are required to provide service. The Company also estimates forfeitures.

Income Taxes

Income Taxes—The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years at tax rates that are expected to apply in those years. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Currency Translation and Transactions

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. Gains or losses resulting from non-U.S. dollar currency transactions are included in other non-operating income in the consolidated statements of operations.

Comprehensive Income

Comprehensive Income—The Company reports all changes in comprehensive income in the consolidated statements of comprehensive income. Comprehensive income includes net income or loss attributable to common stockholders, foreign currency translation gain and loss (net of tax), unrealized gain and loss from available-for-sale investments (net of tax) and reclassification to statements of operations of gain and loss from available-for-sale investments (net of tax).

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements—In February 2015, the Financial Accounting Standards Board (FASB) issued new guidance amending the current accounting for consolidation of certain legal entities. These amendments modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminate the presumption that a general partner should consolidate a limited partnership, affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, and provide a scope exception from consolidation guidance for reporting entities with interests in certain investment funds. This new guidance will be effective for the Company’s first quarter of 2016. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures.

In August 2014, the FASB issued new guidance regarding disclosure of going concern uncertainties in the financial statements. The guidance requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued at each annual and interim reporting period. This new guidance will be effective for the Company’s first quarter of 2017. The Company does not anticipate that the adoption of this new guidance will have a material impact on the Company's consolidated financial statements.

In May 2014, the FASB issued new guidance which outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for the Company's first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption. Early application is prohibited. The Company is currently evaluating the potential impact on its consolidated financial statements and related disclosures, as well as the available transition methods.

In July 2013, the FASB issued new guidance on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryfoward exists. An entity is required to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward unless a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available as of the reporting date or the entity does not intend to use the deferred tax asset for this purpose (provided that the tax law permits a choice). This new guidance was effective for the Company's first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

In June 2013, the FASB issued new guidance which clarifies the characteristics of an investment company and provides guidance for assessing whether an entity is an investment company. From time to time the Company consolidates certain of its affiliated funds which are considered investment companies. The Company retains the specialized investment company accounting for such funds in consolidation. This new guidance was effective for the Company’s first quarter of 2014. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

Valuation Techniques

Valuation Techniques

In certain instances, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable brokers/dealers or pricing services. In determining the value of a particular investment, pricing services may use information with respect to transactions in such investments, broker quotes, pricing matrices, market transactions in comparable investments and various relationships between investments. As part of its independent price verification process, the Company selectively performs detailed reviews of valuations provided by broker/dealers or pricing services.

Foreign exchange contracts are valued by interpolating a value using the spot foreign exchange rate and forward points (based on the spot rate and currency interest rate differentials), which are all inputs that are observable in active markets (level 2).

In the absence of observable market prices, the Company values its investments using valuation methodologies applied on a consistent basis. For some investments, little market activity may exist; management's determination of fair value is then based on the best information available in the circumstances, and may incorporate management's own assumptions and involves a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments are valued on a quarterly basis, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The valuation process also includes a review by the Company's valuation committee which is comprised of senior members from various departments within the Company, including investment management. The valuation committee provides independent oversight of the valuation policies and procedures.
