1. Organization and Description of Business

Cohen & Steers, Inc. (“CNS”) was organized as a Delaware corporation on March 17, 2004. CNS was formed to be the holding company for Cohen & Steers Capital Management, Inc. (“CSCM”), a New York corporation, and to allow for the issuance of common stock to the public.

The condensed consolidated financial statements set forth herein include the accounts of CNS and its direct and indirect subsidiaries. CNS’s wholly-owned subsidiaries are CSCM, Cohen & Steers Securities, LLC (“Securities”), Cohen & Steers Asia Limited, Cohen & Steers UK Limited and Cohen & Steers Europe S.A. (collectively, the “Company”). All material intercompany balances and transactions have been eliminated in consolidation.

Through CSCM, a registered investment advisor under the Investment Advisers Act of 1940 (the “Advisers Act”), the Company serves institutional and individual investors around the world. Founded in 1986, the Company is a leading global investment manager focused on global real estate securities, global listed infrastructure, real assets, large cap value stocks and preferred securities. The Company also manages alternative investment strategies for qualified investors such as hedged real estate securities portfolios and private real estate strategies. Its clients include Company-sponsored open-end and closed-end mutual funds, U.S. and non-U.S. pension plans, endowment funds, foundations and sub-advised funds for other financial institutions. Through Securities, its registered broker/dealer, the Company provides distribution services for certain of its funds.

2. Basis of Presentation and Significant Accounting Policies

The condensed consolidated financial statements of the Company included herein are unaudited and have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the interim results have been made. The Company’s condensed consolidated financial statements and the related notes should be read together with the consolidated financial statements and the related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Accounting Estimates—The preparation of the condensed consolidated financial statements 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the condensed 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. The amounts related to these reclassifications are not material to the Company’s condensed consolidated financial statements.

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The equity method of accounting is used for investments in non-controlled 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. The Company also consolidates any variable interest entities (“VIEs”) in which the Company is the primary beneficiary. The Company provides for noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent.

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, 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.

Securities owned and securities sold but not yet purchased are classified as trading securities 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 securities—net reported in the Company’s condensed consolidated statements of operations.

Investments classified as equity 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. 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 and closed-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 condensed consolidated statements of operations. An other than temporary impairment is generally 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 consolidated funds of the Company enter into derivative contracts 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 securities—net in the Company's condensed consolidated statements of operations. The fair value of these instruments is recorded in other assets or other liabilities and accrued expenses in the Company's condensed consolidated statements of financial condition.

Additionally, from time to time, the Company enters into foreign currency forward 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 condensed consolidated statements of operations. The Company records these contracts as either assets or liabilities in due from broker or other liabilities and accrued expenses, respectively, in its condensed 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. See Note 3 for further discussion about the Company’s goodwill and intangible assets.

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party minority voting 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.

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

Distribution and Service Fees—Distribution and service fee revenue is earned as the services are performed, based on contractually-predetermined percentages of the average assets under management of the Company-sponsored open-end load mutual funds. Distribution and service fee revenue is recorded gross of any third-party distribution and service fee expense arrangements. The expenses associated with these third-party distribution and service fee arrangements are recorded as incurred.

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 condensed 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. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future 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. The effective tax rate for interim periods represents the Company’s best estimate of the effective tax rate expected to be applied to the full fiscal year.

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable condensed consolidated statement of financial condition date. Revenues 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 condensed 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 condensed consolidated statements of operations.

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

Recently Issued Accounting Pronouncements—In October 2012, the Financial Accounting Standards Board (“FASB”) issued new guidance to make certain technical corrections to the FASB Accounting Standards Codification ("Codification"), which identifies when the use of fair value should be linked to the definition of fair value in Codification Topic 820, Fair Value Measurements and Disclosures (“Topic 820”). The amendments affect various Codification topics and include source literature amendments, guidance clarification and reference corrections and relocated guidance. The amendments that will not have transition guidance were effective upon issuance and the amendments that are subject to the transition guidance will be effective for the Company's first quarter of 2013. The adoption of this new guidance did not have and is not expected to have a material impact on the Company's condensed consolidated financial statements.

In July 2012, the FASB issued new guidance to simplify how entities test indefinite-lived intangible assets for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In December 2011, the FASB issued new guidance to create new disclosure requirements about the nature of an entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In September 2011, the FASB issued new guidance to simplify how entities test goodwill for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In June 2011, the FASB issued new guidance eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The new guidance requires changes to the components of net income and comprehensive income in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance should be applied retrospectively. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In May 2011, the FASB issued new guidance regarding fair value measurement and disclosures. The new guidance results in common fair value measurement and disclosure requirements in U.S. Generally Accepted Accounting Principles ("GAAP") and International Financial Reporting Requirements. This new guidance changed the wording used to describe many of the requirements for measuring fair value and for disclosing information about fair value measurements. This new guidance was effective for the Company's first quarter of 2012. See Note 5 for further discussion about the fair value of the Company's investments which incorporates this new guidance.

3. Goodwill and Intangible Assets

Goodwill

Goodwill represents the excess of purchase price over the net tangible assets and identifiable intangible assets of an acquired business. At September 30, 2012 and December 31, 2011, goodwill was approximately $19,824,000 and $19,934,000, respectively. The Company’s goodwill decreased by $110,000 in the nine months ended September 30, 2012 as a result of foreign currency revaluation.

Trading and equity investments

Cohen & Steers Global Realty Partners III-TE, L.P. ("GRP-TE"), which had an initial closing in October 2011, is structured as a partnership. The Company is the general partner and investment manager 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 deemed the primary beneficiary. As the general partner, the Company has significant influence over the financial decisions of GRP-TE and therefore records its investment in this fund using the equity method of accounting. The Company's equity interest in GRP-TE represents a seed investment to launch the fund which was made during the first quarter of 2012, adjusted for the Company’s proportionate share of the fund’s earnings. As of September 30, 2012, the fair value of the Company's equity interest in GRP-TE was approximately $89,000. 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 (“GRP-CIP”), which is used by the Company to fulfill its contractual commitment to co-invest with GRP-TE. See Note 11 for further discussion regarding the Company's co-investment commitment. As of September 30, 2012, the Company owned all of the voting interest in GRP-CIP. Accordingly, the underlying assets and liabilities of GRP-CIP have been included in the Company's condensed consolidated financial statements.

The Cohen & Steers Real Asset Fund (“RAP”), launched by the Company on January 31, 2012, is an open-end mutual fund for which the Company is the investment manager. As of September 30, 2012, the Company had a controlling financial interest in RAP. Accordingly, the underlying assets and liabilities of RAP have been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

Prior to the sale of the Company's interest in Cohen & Steers Global Listed Infrastructure Fund (“GLIF”) during June 2012, the Company owned the majority of the voting interest in GLIF. Accordingly, the underlying assets and liabilities of GLIF had been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

During 2008, the Company launched an onshore global real estate long-short fund (the “Onshore Fund”). As of September 30, 2012, the Company determined that the Onshore Fund was a VIE and the Company was the primary beneficiary. Therefore, the underlying assets and liabilities of the Onshore Fund have been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

The following represents the portion of the consolidated statements of financial condition attributable to the consolidated Onshore Fund as of September 30, 2012 and December 31, 2011.

The offshore global real estate long-short fund (the “Offshore Fund”), launched by the Company in 2008, is structured as a partnership. The Company is the general partner and investment manager of the Offshore Fund for which it receives a management fee and is entitled to receive a performance fee, if earned. As the general partner, the Company has significant influence over the financial decisions of the Offshore Fund and therefore, as of September 30, 2012, records its investment in this fund using the equity method of accounting.

Unrealized losses on investments, available-for-sale as of September 30, 2012 were generally caused by market conditions. When evaluating whether an unrealized loss on an investment, available-for-sale is other than temporary, the Company reviews such factors as 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 September 30, 2012, 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.

Sales proceeds, gross realized gains and losses from investments, available-for-sale for the three and nine months ended September 30, 2012 and 2011 are summarized below (in thousands):

5. Fair Value

Topic 820 defines fair value, establishes a framework for measuring fair value and enhances disclosures about instruments carried at fair value, but does not change existing guidance as to whether or not an instrument should be carried at fair value.

COHEN & STEERS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(UNAUDITED)

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 in active markets.

• 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 three months ended September 30, 2012.

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

Securities owned classified as level 3 in the above table was 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 was valued by the Company's valuation committee using a market approach which utilized market multiples derived from a set of comparables. The limited partnership interests made during 2012 as a co-investment along with GRP-TE represent the Company's ownership interests in private equity vehicles that invest directly in U.S. commercial real estate and were valued primarily based on the recent transaction value of the underlying investments.

Equity investments classified as level 2 in the above table primarily represent the fair value measurement of an equity investment in the Offshore Fund, which is measured at fair value based on the fund's net asset value. The fund makes long and short investments in listed real estate securities to maximize absolute and risk-adjusted returns with modest volatility. The Company has the ability to redeem its investment in the fund monthly at net asset value per share with prior written notice of 30 days and there are no significant restrictions to redemption.

Investments, available-for-sale classified as level 3 in the above table were comprised primarily of auction rate preferred securities which were measured at fair value using a third party pricing service by utilizing 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.

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.

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 unobservable 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 includes primarily senior members from administration departments. The valuation committee provides independent oversight of the valuation policies and procedures.

The valuation technique and significant unobservable inputs used in the fair value measurement of the following Level 3 investments as of September 30, 2012 were (in thousands):

			Fair Value	Significant	Price to Book
	Fair Value		Methodology	Unobservable Inputs	Ratio Range
Common shares of privately-held company	$	1,193	Market comparable companies	Price / book ratio	1.07x - 1.14x
Limited partnership interests	$	2,041	Transaction value	Recent transaction price

The significant unobservable input related to common shares of a privately-held company utilized in the fair value measurement of the level 3 investments in the above table is the price to book ratio. Significant changes in this input may result in a materially higher or lower fair value measurement. The disclosure in the above table 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.

7. Earnings Per Share

Basic earnings per share are calculated by dividing net income attributable to common shareholders by the weighted average shares outstanding. Diluted earnings per share are calculated by dividing net income attributable to common shareholders 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 three and nine months ended September 30, 2012. No anti-dilutive common stock equivalents were excluded from the computation for the three months ended September 30, 2011. Anti-dilutive common stock equivalents of approximately 3,000 shares were excluded from the computation for the nine months ended September 30, 2011.

Diluted earnings per share attributable to common shareholders	$	0.23		$	0.22	$	1.00		$	0.87

8. Income Taxes

The provision for income taxes for the three and nine months ended September 30, 2012 includes U.S. federal, state, local and foreign taxes at an approximate effective tax rate of 33% and 35%, respectively, which included discrete items, the most significant of which was attributable to the launch costs of Cohen & Steers Limited Duration Preferred and Income Fund, Inc. ("LDP"), a closed-end mutual fund. Excluding the discrete items, the effective tax rate for the three and nine months ended September 30, 2012 was approximately 36%. The effective tax rate for the three and nine months ended September 30, 2011 was approximately 46% and 38%, respectively. The effective tax rate for the three months ended September 30, 2011 reflected the cumulative effect of the projected tax rate increase from 35% to 38% for the full year 2011 which resulted primarily from a valuation allowance established on projected losses from the Company's seed investments in the onshore and offshore global real estate long-short funds. The Company expects the tax rate for the full year 2012 to approximate 35.5%, excluding discrete items.

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's net deferred tax asset is primarily comprised of future income tax deductions attributable to the delivery of unvested restricted stock units. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

9. Regulatory Requirements

Securities, a registered broker/dealer in the U.S., is subject to the SEC’s Uniform Net Capital Rule 15c3-1 (the “Rule”), which requires that broker/dealers maintain a minimum level of net capital, as defined. As of September 30, 2012, Securities had net capital of approximately $733,000, which exceeded its requirements by approximately $669,000. The Rule also provides that equity capital may not be withdrawn or cash dividends paid if the resulting net capital of a broker/dealer is less than the amount required under the Rule and requires prior notice to the SEC for certain withdrawals of capital.

These investment advisory agreements contractually require the Company to waive a portion of the advisory fees the Company otherwise would charge for up to ten years from the respective fund's inception date. The board of directors of these mutual funds must approve the renewal of the advisory agreements each year, including any reduction in advisory fee waivers scheduled to take effect during that year.

11. Commitments and Contingencies

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 business or financial condition.

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 5%, up to $25 million, of the total capital raised in Cohen & Steers Global Realty Partners III ("GRP"), a global private equity multimanager fund that had an initial closing on October 4, 2011, and such co-investment will be invested in GRP for up to 12 years through the life of the fund. The ultimate co-investment amount and actual timing of the funding of this commitment is currently unknown, as the co-investment amount will be based on investor commitments to GRP through March 2013, and the drawdown of the Company's commitment is contingent on the timing of drawdowns by the underlying funds and co-investments in which GRP invests. This unfunded commitment was not recorded on the Company's condensed consolidated statements of financial condition as of September 30, 2012.

Average assets under management in the three months ended September 30, 2012 were $45.2 billion compared with $42.9 billion in the three months ended September 30, 2011.

in closed-end mutual fund revenue was attributable to higher average assets under management. Average assets under management for closed-end mutual funds in the three months ended September 30, 2012 were $7.3 billion compared with $6.5 billion in the three months ended September 30, 2011.

In the three months ended September 30, 2012, total portfolio consulting and other revenue increased to $5.2 million from $1.1 million in the three months ended September 30, 2011. The increase was attributable to higher average assets under advisement from model-based strategies.

Expenses

Total operating expenses increased 51% to $59.1 million in the three months ended September 30, 2012 from $39.2 million in the three months ended September 30, 2011, primarily due to increases in employee compensation and benefits, distribution and service fees and general and administrative expenses.

Employee compensation and benefits increased 15% to $25.1 million in the three months ended September 30, 2012 from $21.9 million in the three months ended September 30, 2011, primarily due to higher incentive bonus and production compensation, net of deferrals, of approximately $2.6 million.

Distribution and service fee expenses increased to $21.4 million in the three months ended September 30, 2012 from $6.2 million in the three months ended September 30, 2011. The three months ended September 30, 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 $7.0 million. The increase was primarily due to higher average assets under management in certain of our open-end no-load mutual funds.

General and administrative expenses increased 13% to $10.6 million in the three months ended September 30, 2012 from $9.4 million in the three months ended September 30, 2011. The increase was primarily due to higher rent of approximately $632,000 resulting from the extension of the lease for our corporate headquarters in New York City, higher professional fees of approximately $318,000 and higher marketing and printing costs of approximately $188,000.

Non-operating Income

Non-operating income was $5.3 million in the three months ended September 30, 2012, compared with non-operating loss of $4.8 million in the three months ended September 30, 2011. The increase was primarily attributable to income from our seed investments.

Income Taxes

We recorded an income tax expense of $5.0 million in the three months ended September 30, 2012, compared with $8.0 million in the three months ended September 30, 2011. The provision for income taxes in the three months ended September 30, 2012 included U.S. federal, state, local and foreign taxes at an approximate effective tax rate of 33%, which included discrete items, the most significant of which was attributable to the offering costs for LDP. Excluding the discrete items, the effective tax rate for the three months ended September 30, 2012 was approximately 36%. The effective tax rate for the three months ended September 30, 2011 was approximately 46%, which reflected the cumulative effect of the projected tax rate increase from 35% to 38% for the full year 2011. The change in estimate was attributable to the establishment of a valuation allowance on projected losses from our seed investments in our sponsored onshore and offshore global real estate long-short funds. We expect our tax rate for the full year 2012 to approximate 35.5%, excluding discrete items.

Revenue

Total revenue increased 14% to $202.5 million in the nine months ended September 30, 2012 from $177.8 million in the nine months ended September 30, 2011. This increase was primarily attributable to higher investment advisory and administration fees resulting from higher average assets under management and higher portfolio consulting and other revenue attributable to higher average assets under advisement from model-based strategies. Average assets under management in the nine months ended September 30, 2012 were $44.0 billion compared with $40.0 billion in the nine months ended September 30, 2011.

In the nine months ended September 30, 2012, total investment advisory and administration revenue from institutional accounts increased 1% to $67.2 million from $66.5 million in the nine months ended September 30, 2011. The increase in institutional account revenue was attributable to higher levels of average assets under management. Average assets under management for institutional accounts in the nine months ended September 30, 2012 were $25.6 billion compared with $23.9 billion in the nine months ended September 30, 2011.

In the nine months ended September 30, 2012, total investment advisory and administration revenue from open-end mutual funds increased 19% to $70.8 million from $59.3 million in the nine months ended September 30, 2011. The increase in open-end mutual fund revenue was attributable to higher levels of average assets under management. Average assets under management for open-end mutual funds in the nine months ended September 30, 2012 were $11.5 billion compared with $9.4 billion in the nine months ended September 30, 2011.

In the nine months ended September 30, 2012, total investment advisory and administration revenue from closed-end mutual funds increased 5% to $43.0 million from $40.9 million in the nine months ended September 30, 2011. The increase in closed-end mutual fund revenue was attributable to higher levels of average assets under management. Average assets under management for closed-end mutual funds in the nine months ended September 30, 2012 were $6.8 billion compared with $6.6 billion in the nine months ended September 30, 2011.

In the nine months ended September 30, 2012, total portfolio consulting and other revenue increased 249% to $13.3 million from $3.8 million in the nine months ended September 30, 2011. The increase was attributable to higher average assets under advisement from model-based strategies.

Expenses

Total operating expenses increased 22% to $138.8 million in the nine months ended September 30, 2012 from $113.6 million in the nine months ended September 30, 2011, primarily due to increases in employee compensation and benefits, distribution and service fees and general and administrative expenses.

Employee compensation and benefits increased 9% to $69.7 million in the nine months ended September 30, 2012 from $63.7 million in the nine months ended September 30, 2011. The increase was primarily due to higher incentive bonus and production compensation, net of deferrals, of approximately $3.6 million, higher salaries of approximately $601,000 and higher payroll taxes of approximately $273,000 associated with the delivery of restricted stock units.

Distribution and service fee expenses increased 89% to $34.1 million in the nine months ended September 30, 2012 from $18.1 million in the nine months ended September 30, 2011. The nine months ended September 30, 2012 results included approximately $14.4 million of distribution costs associated with the launch of LDP. After adjusting for these costs, dist

28

ribution and service fee expenses would have been $19.8 million. The increase was primarily due to higher average assets under management in certain of our open-end no-load mutual funds.

General and administrative expenses increased 8% to $29.1 million in the nine months ended September 30, 2012 from $26.8 million in the nine months ended September 30, 2011. The increase was primarily due to higher professional fees of approximately $927,000, higher rent of approximately $736,000 resulting from the extension of the lease for our corporate headquarters in New York City and higher marketing and printing costs of approximately $369,000.

Non-operating Income

Non-operating income was $6.3 million in the nine months ended September 30, 2012, compared with non-operating loss of $2.6 million in the nine months ended September 30, 2011. The increase was primarily attributable to earnings in our seed investments, partially offset by foreign currency revaluations.

Income Taxes

We recorded an income tax expense of $24.2 million in the nine months ended September 30, 2012, compared with $23.5 million in the nine months ended September 30, 2011. The provision for income taxes in the nine months ended September 30, 2012 included U.S. federal, state, local and foreign taxes at an approximate effective tax rate of 35%, which included discrete items, the most significant of which was attributable to the offering costs for LDP. Excluding the discrete items, the effective tax rate for the nine months ended September 30, 2012 was approximately 36%. The effective tax rate for the nine months ended September 30, 2011 was approximately 38%. We expect our tax rate for the full year 2012 to approximate 35.5%, excluding discrete items.

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, equity investments, investments, available-for-sale 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 investments, investments, available-for-sale and accounts receivable were 58% and 69% of total assets as of September 30, 2012 and December 31, 2011, respectively, excluding investments classified as level 3 in accordance with the Accounting Standard Codification (the “Codification”) Topic 820, Fair Value Measurements and Disclosures (“Topic 820”).

Cash and cash equivalents decreased by $6.5 million, excluding the effect of foreign exchange rate changes, in the nine months ended September 30, 2012. Net cash used in operating activities was $21.7 million in the nine months ended September 30, 2012. Net cash of $3.6 million was provided by investing activities, primarily from proceeds from sales of investments, available-for-sale in the amount of $23.7 million, partially offset by purchases of $18.5 million of investments, available-for-sale and purchases of $2.4 million of property and equipment. Net cash of $11.6 million was provided by financing activities, primarily from contributions from redeemable noncontrolling interest of $44.1 million and excess tax benefits associated with the delivery of restricted stock units of $2.8 million, partially offset by dividends paid to stockholders of $23.6 million, repurchases of common stock of $8.5 million to satisfy employee withholding tax obligations on the delivery of restricted stock units, and redemptions of redeemable noncontrolling interest of $3.6 million.

Cash and cash equivalents decreased by $41.7 million, excluding the effect of foreign exchange rate changes, in the nine months ended September 30, 2011. Net cash provided by operating activities was $43.8 million in the nine months ended September 30, 2011. Net cash of $14.3 million was used in investing activities, primarily for purchases of $32.9 million of investments, available-for-sale and purchases of $2.2 million of property and equipment, partially offset by proceeds from sales of investments, available-for-sale in the amount of $20.8 million. Net cash of $71.1 million was used in financing activities, primarily for dividends paid to stockholders of $62.6 million, which included a special dividend of approximately $43.2 million paid on September 28, 2011, repurchases of common stock of $6.6 million to satisfy employee withholding tax obligations on the delivery of restricted stock units, and redemptions of redeemable noncontrolling interest of $3.7 million, partially offset by excess tax benefits associated with the delivery of restricted stock units of $1.5 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 September 30, 2012, we exceeded our minimum regulatory capital requirements by approximately $669,000. The SEC’s Uniform Net Capital Rule 15c3-1 imposes certain requirements that may have the effect of prohibiting

29

a broker/dealer from distributing or withdrawing capital and requiring prior notice to the SEC for certain withdrawals of capital. Our non-U.S. subsidiaries are regulated outside the U.S. by the Hong Kong Securities and Future Commission, the United Kingdom Financial Securities Authority, and the Belgium Financial Services and Markets Authority. At September 30, 2012, our non-U.S. subsidiaries exceeded their aggregate minimum regulatory requirements by approximately $64.8 million. We believe that our 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 and investments, available-for-sale were approximately $76.6 million held by our foreign subsidiaries as of September 30, 2012, including amounts held by Cohen & Steers Europe S.A. We are currently considering a reorganization of Cohen & Steers Europe S.A., which may result in funds moving to the U.S. Based on our preliminary review, we believe the reorganization, if effected, should not result in any tax on repatriated funds. Otherwise, it is our current intention to permanently reinvest funds held by our foreign subsidiaries outside of the U.S. 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.

We periodically commit to fund a portion of the equity in certain of our sponsored investment products. We have committed to co-invest 5%, up to $25 million, of the total capital raised in Cohen & Steers Global Realty Partners III-TE, L.P. ("GRP-TE"), a global private equity multimanager fund that had an initial closing on October 4, 2011. Our investment with GRP-TE is illiquid and will be invested for up to 12 years through the life of the fund. The ultimate co-investment amount and actual timing of the funding of this commitment is currently unknown, as the co-investment amount will be based on investor commitments to GRP-TE through March 2013, and 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 condensed consolidated statements of financial condition as of September 30, 2012.

Contractual Obligations and Contingencies

We have contractual obligations to make future payments in connection with our non-cancelable operating lease agreements for office space. There were no material capital lease obligations as of September 30, 2012. The following summarizes our contractual obligations as of September 30, 2012 (in thousands):

	2012		2013		2014		2015		2016		2017 and after		Total
Operating leases	$	2,021	$	8,085	$	7,875	$	8,990	$	8,745	$	64,215	$	99,931

On June 29, 2012, we extended the lease for our corporate headquarters in New York City to 2024. See Note 11 for further discussion about our commitments and contingencies.

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 condensed consolidated financial statements.

Critical Accounting Policies and Estimates

The preparation of our condensed consolidated financial statements 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. We believe the estimates used in preparing the condensed consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.

A thorough understanding of our accounting policies is essential when reviewing our reported results of operations and our financial position. Management considers the following accounting policies critical to an informed review of our condensed consolidated financial statements. For a summary of these and additional accounting policies, see the notes to the annual audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2011.

Investments

We determine the appropriate classification of our investments at the time of purchase and re-evaluate such determination at each statement of financial condition date.

Securities owned and securities sold but not yet purchased are classified as trading securities 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 our valuation committee. Unrealized gains and losses are recorded as gain (loss) from trading securities reported in our condensed consolidated statements of operations.

Investments classified as equity investments are accounted for using the equity method, under which we recognize our respective share of the investee’s net income or loss for the period. 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 our sponsored open-end and closed-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. We periodically review each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other than temporary. If we believe an impairment of a security position is other than temporary, the loss will be recognized in our condensed consolidated statements of operations. An other than temporary impairment is generally presumed to have occurred if the available-for-sale investment has an unrealized loss continuously for 12 or more months.

From time to time, our consolidated funds enter into derivative contracts 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 securities—net in our condensed consolidated statements of operations. The fair value of these instruments are recorded in other assets or other liabilities and accrued expenses in our condensed consolidated statements of financial condition.

Additionally, from time to time, we enter into foreign currency forward contracts to hedge our currency exposure related to client receivables. These instruments are measured at fair value with gains and losses recorded in other non-operating income in our condensed consolidated statements of operations. We record these contracts as either assets or liabilities in due from broker or other liabilities and accrued expenses, respectively, in our condensed consolidated statements of financial condition.

Goodwill and Intangible Assets

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 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. We determined that the fair values of our goodwill and indefinite lived intangible assets substantially exceeded their carrying values as a result of the most recent impairment test performed as of November 30, 2011.

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. We also estimate forfeitures.

Income Taxes

We record the current and deferred tax consequences of all transactions that have been recognized in the condensed 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. 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. The effective tax rate for interim periods represents our best estimate of the effective tax rate expected to be applied to the full fiscal year.

Recently Issued Accounting Pronouncements

In October 2012, the Financial Accounting Standards Board (“FASB”) issued new guidance to make certain technical corrections to the FASB Accounting Standards Codification ("Codification"), which identifies when the use of fair value should be linked to the definition of fair value in Topic 820. The amendments affect various Codification topics and include source literature amendments, guidance clarification and reference corrections and relocated guidance. The amendments that will not have transition guidance were effective upon issuance and the amendments that are subject to the transition guidance will be effective for the first quarter of our 2013 fiscal year. The adoption of this new guidance did not have and is not expected to have a material impact on our condensed consolidated financial statements.

In July 2012, the FASB issued new guidance to simplify how entities test indefinite-lived intangible assets for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance will be effective for the first quarter of our 2013 fiscal year. We do not anticipate the adoption of this new guidance to have a material impact on our condensed consolidated financial statements.

In December 2011, the FASB issued new guidance to create new disclosure requirements about the nature of an entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. This new guidance will be effective for the first quarter of our 2013 fiscal year. We do not anticipate the adoption of this new guidance to have a material impact on our condensed consolidated financial statements.

In September 2011, the FASB issued new guidance to simplify how entities test goodwill for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance was effective for the first quarter of our 2012 fiscal year. The adoption of this new guidance did not have a material impact on our condensed consolidated financial statements.

In June 2011, the FASB issued new guidance eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The new guidance requires changes to the components of net income and comprehensive income in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance should be applied retrospectively. In December 2011, the FASB issued guidance to defer the effective date for amendments to the presentation of reclassifications of items out of accumulated other comprehensive income. This new guidance was effective for the first quarter of our 2012 fiscal year. The adoption of this new guidance did not have a material impact on our condensed consolidated financial statements.

In May 2011, the FASB issued new guidance regarding fair value measurement and disclosures. The new guidance results in common fair value measurement and disclosure requirements in U.S. Generally Accepted Accounting Principles ("GAAP") and International Financial Reporting Requirements. This new guidance changed the wording used to describe many of the requirements for measuring fair value and for disclosing information about fair value measurements. This new guidance was effective for the first quarter of our 2012 fiscal year. See Note 5 for further discussion about the fair value of our investments which incorporates this new guidance.

Basis of Presentation and Significant Accounting Policies [Abstract]

Accounting Estimates [Policy Text Block]

Accounting Estimates—The preparation of the condensed consolidated financial statements 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the condensed consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.

Reclassifications [Policy Text Block]

Reclassifications—Certain prior year amounts have been reclassified to conform to the current year presentation. The amounts related to these reclassifications are not material to the Company’s condensed consolidated financial statements

Consolidation [Policy Text Block]

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The equity method of accounting is used for investments in non-controlled 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. The Company also consolidates any variable interest entities (“VIEs”) in which the Company is the primary beneficiary. The Company provides for noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent.

VIE [Policy Text Block]

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 [Policy Text Block]

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 [Policy Text Block]

Due from Broker—The Company conducts business, 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 [Policy Text Block]

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.

Goodwill and Intangible Assets [Policy Text Block]

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. See Note 3 for further discussion about the Company’s goodwill and intangible assets.

Redeemable Noncontrolling Interest [Policy Text Block]

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party minority voting 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.

Investment Advisory and Administrative Fees [Policy Text Block]

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

Distribution and Service Fees [Policy Text Block]

Distribution and Service Fees—Distribution and service fee revenue is earned as the services are performed, based on contractually-predetermined percentages of the average assets under management of the Company-sponsored open-end load mutual funds. Distribution and service fee revenue is recorded gross of any third-party distribution and service fee expense arrangements. The expenses associated with these third-party distribution and service fee arrangements are recorded as incurred.

Stock-based Compensation [Policy Text Block]

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 [Policy Text Block]

Income Taxes—The Company records the current and deferred tax consequences of all transactions that have been recognized in the condensed 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. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future 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. The effective tax rate for interim periods represents the Company’s best estimate of the effective tax rate expected to be applied to the full fiscal year.

Currency Translation and Transactions [Policy Text Block]

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable condensed consolidated statement of financial condition date. Revenues and expenses are translated at average exchange rates during the period.

Comprehensive Income, Policy [Policy Text Block]

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

Recently Issued Accounting Pronouncements [Policy Text Block]

Recently Issued Accounting Pronouncements—In October 2012, the Financial Accounting Standards Board (“FASB”) issued new guidance to make certain technical corrections to the FASB Accounting Standards Codification ("Codification"), which identifies when the use of fair value should be linked to the definition of fair value in Codification Topic 820, Fair Value Measurements and Disclosures (“Topic 820”). The amendments affect various Codification topics and include source literature amendments, guidance clarification and reference corrections and relocated guidance. The amendments that will not have transition guidance were effective upon issuance and the amendments that are subject to the transition guidance will be effective for the Company's first quarter of 2013. The adoption of this new guidance did not have and is not expected to have a material impact on the Company's condensed consolidated financial statements.

In July 2012, the FASB issued new guidance to simplify how entities test indefinite-lived intangible assets for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In December 2011, the FASB issued new guidance to create new disclosure requirements about the nature of an entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In September 2011, the FASB issued new guidance to simplify how entities test goodwill for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In June 2011, the FASB issued new guidance eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The new guidance requires changes to the components of net income and comprehensive income in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance should be applied retrospectively. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In May 2011, the FASB issued new guidance regarding fair value measurement and disclosures. The new guidance results in common fair value measurement and disclosure requirements in U.S. Generally Accepted Accounting Principles ("GAAP") and International Financial Reporting Requirements. This new guidance changed the wording used to describe many of the requirements for measuring fair value and for disclosing information about fair value measurements. This new guidance was effective for the Company's first quarter of 2012. See Note 5 for further discussion about the fair value of the Company's investments which incorporates this new guidance.

Fair Value of Financial Instruments, Policy [Policy Text Block]

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.

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 unobservable 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 includes primarily senior members from administration departments. The valuation committee provides independent oversight of the valuation policies and procedures.

Regulatory Requirements

Regulatory Requirements

Trading and equity investments

Cohen & Steers Global Realty Partners III-TE, L.P. ("GRP-TE"), which had an initial closing in October 2011, is structured as a partnership. The Company is the general partner and investment manager 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 deemed the primary beneficiary. As the general partner, the Company has significant influence over the financial decisions of GRP-TE and therefore records its investment in this fund using the equity method of accounting. The Company's equity interest in GRP-TE represents a seed investment to launch the fund which was made during the first quarter of 2012, adjusted for the Company’s proportionate share of the fund’s earnings. As of September 30, 2012, the fair value of the Company's equity interest in GRP-TE was approximately $89,000. 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 (“GRP-CIP”), which is used by the Company to fulfill its contractual commitment to co-invest with GRP-TE. See Note 11 for further discussion regarding the Company's co-investment commitment. As of September 30, 2012, the Company owned all of the voting interest in GRP-CIP. Accordingly, the underlying assets and liabilities of GRP-CIP have been included in the Company's condensed consolidated financial statements.

The Cohen & Steers Real Asset Fund (“RAP”), launched by the Company on January 31, 2012, is an open-end mutual fund for which the Company is the investment manager. As of September 30, 2012, the Company had a controlling financial interest in RAP. Accordingly, the underlying assets and liabilities of RAP have been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

Prior to the sale of the Company's interest in Cohen & Steers Global Listed Infrastructure Fund (“GLIF”) during June 2012, the Company owned the majority of the voting interest in GLIF. Accordingly, the underlying assets and liabilities of GLIF had been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

During 2008, the Company launched an onshore global real estate long-short fund (the “Onshore Fund”). As of September 30, 2012, the Company determined that the Onshore Fund was a VIE and the Company was the primary beneficiary. Therefore, the underlying assets and liabilities of the Onshore Fund have been included in the Company's condensed consolidated financial statements with the third party interests classified as redeemable noncontrolling interest.

The following represents the portion of the consolidated statements of financial condition attributable to the consolidated Onshore Fund as of September 30, 2012 and December 31, 2011. The following assets may only be used to settle obligations of the Onshore Fund and these liabilities are only the obligations of the Onshore Fund for which the creditors do not have recourse to the general credit of the Company (in thousands):

The offshore global real estate long-short fund (the “Offshore Fund”), launched by the Company in 2008, is structured as a partnership. The Company is the general partner and investment manager of the Offshore Fund for which it receives a management fee and is entitled to receive a performance fee, if earned. As the general partner, the Company has significant influence over the financial decisions of the Offshore Fund and therefore, as of September 30, 2012, records its investment in this fund using the equity method of accounting. The Company’s equity interest in the Offshore Fund represents a seed investment to launch the fund, adjusted for the Company’s proportionate share of the fund’s earnings.

Unrealized losses on investments, available-for-sale as of September 30, 2012 were generally caused by market conditions. When evaluating whether an unrealized loss on an investment, available-for-sale is other than temporary, the Company reviews such factors as 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 September 30, 2012, 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.

Sales proceeds, gross realized gains and losses from investments, available-for-sale for the three and nine months ended September 30, 2012 and 2011 are summarized below (in thousands):

Commitments and Contingencies

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 business or financial condition.

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 5%, up to $25 million, of the total capital raised in Cohen & Steers Global Realty Partners III ("GRP"), a global private equity multimanager fund that had an initial closing on October 4, 2011, and such co-investment will be invested in GRP for up to 12 years through the life of the fund. The ultimate co-investment amount and actual timing of the funding of this commitment is currently unknown, as the co-investment amount will be based on investor commitments to GRP through March 2013, and the drawdown of the Company's commitment is contingent on the timing of drawdowns by the underlying funds and co-investments in which GRP invests. This unfunded commitment was not recorded on the Company's condensed consolidated statements of financial condition as of September 30, 2012.

On June 29, 2012, the Company extended the lease for its corporate headquarters in New York City for an added 10 year period through January 2024.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share are calculated by dividing net income attributable to common shareholders by the weighted average shares outstanding. Diluted earnings per share are calculated by dividing net income attributable to common shareholders 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 three and nine months ended September 30, 2012. No anti-dilutive common stock equivalents were excluded from the computation for the three months ended September 30, 2011. Anti-dilutive common stock equivalents of approximately 3,000 shares were excluded from the computation for the nine months ended September 30, 2011.

The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the three and nine months ended September 30, 2012 and 2011 (in thousands, except per share data):

Fair Value [Abstract]

Fair Value [Text Block]

Fair Value

Topic 820 defines fair value, establishes a framework for measuring fair value and enhances disclosures about instruments carried at fair value, but does not change existing guidance as to whether or not an instrument should be carried at fair value.

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 in active markets.

• 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 three months ended September 30, 2012.

The following table presents fair value measurements as of September 30, 2012 (in thousands):

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

Securities owned classified as level 3 in the above table was 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 was valued by the Company's valuation committee using a market approach which utilized market multiples derived from a set of comparables. The limited partnership interests made during 2012 as a co-investment along with GRP-TE represent the Company's ownership interests in private equity vehicles that invest directly in U.S. commercial real estate and were valued primarily based on the recent transaction value of the underlying investments.

Equity investments classified as level 2 in the above table primarily represent the fair value measurement of an equity investment in the Offshore Fund, which is measured at fair value based on the fund's net asset value. The fund makes long and short investments in listed real estate securities to maximize absolute and risk-adjusted returns with modest volatility. The Company has the ability to redeem its investment in the fund monthly at net asset value per share with prior written notice of 30 days and there are no significant restrictions to redemption.

Investments, available-for-sale classified as level 3 in the above table were comprised primarily of auction rate preferred securities which were measured at fair value using a third party pricing service by utilizing 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 had no level 3 investments during the three and nine months ended September 30, 2011.

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

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 unobservable 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 includes primarily senior members from administration departments. The valuation committee provides independent oversight of the valuation policies and procedures.

The valuation technique and significant unobservable inputs used in the fair value measurement of the following Level 3 investments as of September 30, 2012 were (in thousands):

			Fair Value	Significant	Price to Book
	Fair Value		Methodology	Unobservable Inputs	Ratio Range
Common shares of privately-held company	$	1,193	Market comparable companies	Price / book ratio	1.07x - 1.14x
Limited partnership interests	$	2,041	Transaction value	Recent transaction price

The significant unobservable input related to common shares of a privately-held company utilized in the fair value measurement of the level 3 investments in the above table is the price to book ratio. Significant changes in this input may result in a materially higher or lower fair value measurement. The disclosure in the above table 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.

Income Taxes

The provision for income taxes for the three and nine months ended September 30, 2012 includes U.S. federal, state, local and foreign taxes at an approximate effective tax rate of 33% and 35%, respectively, which included discrete items, the most significant of which was attributable to the launch costs of Cohen & Steers Limited Duration Preferred and Income Fund, Inc. ("LDP"), a closed-end mutual fund. Excluding the discrete items, the effective tax rate for the three and nine months ended September 30, 2012 was approximately 36%. The effective tax rate for the three and nine months ended September 30, 2011 was approximately 46% and 38%, respectively. The effective tax rate for the three months ended September 30, 2011 reflected the cumulative effect of the projected tax rate increase from 35% to 38% for the full year 2011 which resulted primarily from a valuation allowance established on projected losses from the Company's seed investments in the onshore and offshore global real estate long-short funds. The Company expects the tax rate for the full year 2012 to approximate 35.5%, excluding discrete items.

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's net deferred tax asset is primarily comprised of future income tax deductions attributable to the delivery of unvested restricted stock units. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Basis of Presentation and Significant Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies [Text Block]

Basis of Presentation and Significant Accounting Policies

The condensed consolidated financial statements of the Company included herein are unaudited and have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the interim results have been made. The Company’s condensed consolidated financial statements and the related notes should be read together with the consolidated financial statements and the related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Accounting Estimates—The preparation of the condensed consolidated financial statements 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the condensed 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. The amounts related to these reclassifications are not material to the Company’s condensed consolidated financial statements.

Consolidation—The Company consolidates operating entities deemed to be voting interest entities if the Company owns a majority of the voting interest. The equity method of accounting is used for investments in non-controlled 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. The Company also consolidates any variable interest entities (“VIEs”) in which the Company is the primary beneficiary. The Company provides for noncontrolling interests in consolidated subsidiaries for which the Company’s ownership is less than 100 percent.

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, 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.

Securities owned and securities sold but not yet purchased are classified as trading securities 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 securities—net reported in the Company’s condensed consolidated statements of operations.

Investments classified as equity 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. 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 and closed-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 condensed consolidated statements of operations. An other than temporary impairment is generally 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 consolidated funds of the Company enter into derivative contracts 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 securities—net in the Company's condensed consolidated statements of operations. The fair value of these instruments is recorded in other assets or other liabilities and accrued expenses in the Company's condensed consolidated statements of financial condition.

Additionally, from time to time, the Company enters into foreign currency forward 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 condensed consolidated statements of operations. The Company records these contracts as either assets or liabilities in due from broker or other liabilities and accrued expenses, respectively, in its condensed 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. See Note 3 for further discussion about the Company’s goodwill and intangible assets.

Redeemable Noncontrolling Interest—Redeemable noncontrolling interest represents third-party minority voting 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.

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

Distribution and Service Fees—Distribution and service fee revenue is earned as the services are performed, based on contractually-predetermined percentages of the average assets under management of the Company-sponsored open-end load mutual funds. Distribution and service fee revenue is recorded gross of any third-party distribution and service fee expense arrangements. The expenses associated with these third-party distribution and service fee arrangements are recorded as incurred.

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 condensed 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. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future 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. The effective tax rate for interim periods represents the Company’s best estimate of the effective tax rate expected to be applied to the full fiscal year.

Currency Translation and Transactions—Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable condensed consolidated statement of financial condition date. Revenues 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 condensed 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 condensed consolidated statements of operations.

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

Recently Issued Accounting Pronouncements—In October 2012, the Financial Accounting Standards Board (“FASB”) issued new guidance to make certain technical corrections to the FASB Accounting Standards Codification ("Codification"), which identifies when the use of fair value should be linked to the definition of fair value in Codification Topic 820, Fair Value Measurements and Disclosures (“Topic 820”). The amendments affect various Codification topics and include source literature amendments, guidance clarification and reference corrections and relocated guidance. The amendments that will not have transition guidance were effective upon issuance and the amendments that are subject to the transition guidance will be effective for the Company's first quarter of 2013. The adoption of this new guidance did not have and is not expected to have a material impact on the Company's condensed consolidated financial statements.

In July 2012, the FASB issued new guidance to simplify how entities test indefinite-lived intangible assets for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In December 2011, the FASB issued new guidance to create new disclosure requirements about the nature of an entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. This new guidance will be effective for the Company's first quarter of 2013. The Company does not anticipate the adoption of this new guidance to have a material impact on the Company's condensed consolidated financial statements.

In September 2011, the FASB issued new guidance to simplify how entities test goodwill for impairment. The new guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the second step to measure the amount of the impairment loss, if any. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In June 2011, the FASB issued new guidance eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The new guidance requires changes to the components of net income and comprehensive income in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance should be applied retrospectively. This new guidance was effective for the Company's first quarter of 2012. The adoption of this new guidance did not have a material impact on the Company's condensed consolidated financial statements.

In May 2011, the FASB issued new guidance regarding fair value measurement and disclosures. The new guidance results in common fair value measurement and disclosure requirements in U.S. Generally Accepted Accounting Principles ("GAAP") and International Financial Reporting Requirements. This new guidance changed the wording used to describe many of the requirements for measuring fair value and for disclosing information about fair value measurements. This new guidance was effective for the Company's first quarter of 2012. See Note 5 for further discussion about the fair value of the Company's investments which incorporates this new guidance.
