To Our Shareholders:

We are pleased to submit to you our report for the six months ended June 30, 2007. The net asset value at that date was $82.15 per share. In addition, a regular distribution of $0.534 per share was declared for shareholders of record on June 28, 2007 and was paid on June 29, 2007.^a

The total return, including income and change in net asset value, for Cohen & Steers Realty Shares and the comparative benchmarks were:

Investment Review

Following four years of strong absolute and relative performance, including a 35% total return in 2006 (as measured by the FTSE NAREIT Equity REIT Index) and seven years of positive returns, REITs had generally negative returns in the first half of 2007. REITs began the year on a positive note, buoyed by a January bidding contest between Vornado and The Blackstone Group for control of Equity Office Properties (EOP). Blackstone prevailed, purchasing EOP at a sizable premium, prompting investors at that time to raise valuation estimates for publicly traded real estate securities.

^a  Please note that distributions paid by the fund to shareholders are subject to recharacterization for tax purposes. The final tax treatment of these distributions is reported to shareholders after the close of each fiscal year.

^b  The FTSE NAREIT Equity REIT Index is an unmanaged, market capitalization weighted index of all publicly traded REITs that invest predominantly in the equity ownership of real estate. The index is designed to reflect the performance of all publicly traded equity REITs as a whole. The S&P 500 Index is an unmanaged index of common stocks that is frequently used as a general measure of stock market performance.

REITs struggled over the remainder of the period, however, declining nearly 20% from their February highs. This reflected concerns over rising interest rates and uncertainty about whether asset pricing would suffer. Expectations for Federal Reserve monetary easing were pushed back as economic growth continued and inflation fears persisted. The possibility that the Fed might in fact raise rates entered the picture, and the yield on the 10-year Treasury bond in June climbed to 5.26%, its highest level in five years; the yield retreated to 5.03% by period end.

Growth rates for real estate companies generally stabilized, after accelerating in the past few years. This signaled an end to the stock-multiple expansion phase of the real estate cycle, and set expectations for more normalized returns for REITs. Put another way, capitalization rate compression for real estate assets is likely over (a cap rate is the inverse of the earnings multiple).

Most property sectors declined. Among the poorest performing sectors were self storage, due to concerns that a slowing economy might materially affect demand; and health care, as these companies are typically more sensitive to rising interest rates, due to the long-term nature of their leases.

Apartments stage partial recovery

Apartments initially underperformed on concerns about the weakening housing market. However, the group's performance improved late in the period when Archstone-Smith, a leading apartment REIT, agreed to be acquired by a partnership sponsored by Tishman Speyer and Lehman Brothers for $22.2 billion, a 22.7% premium to the stock price before a rumor of the deal was published on May 24, 2007. This deal underscored for the market the overall positive prospects for apartment fundamentals and the sustainability of apartment asset pricing. The sector outperformed for the period as a whole.

The hotel sector, which was generally inexpensive relative to other property sectors coming into the period, outperformed. Merger activity stimulated the group's relative performance. Late in the quarter, Equity Inns, the third-largest hotel REIT as measured by the number of hotels owned, announced that it would be acquired by an affiliate of Whitehall Street Global Real Estate in a transaction valued at $2.2 billion. This represented a 19% premium to the stock's previous day closing price.

Relative performance hindered by self storage, aided by health care

The fund underperformed its benchmark, hindered by our overweight in the self-storage sector. Our underweight in regional malls was a detractor, as the sector outperformed despite a poor second quarter. Stock selection in the apartment, diversified and hotel sectors also hampered the fund's performance. Factors that aided the fund's relative return included our underweight in health care and stock selection in the office sector.

Investment Outlook

Before REITs can manage a sustainable performance recovery, investors may require more clarity on inflation and economic growth. In our opinion, if the economy gains momentum, it would likely benefit real estate companies; however, it might cause the Fed to raise interest rates, unsettling stock prices, including REITs. A cooling economy, on the other hand, would likely prompt the Fed to cut rates, which could lift stocks, as a rate reduction is not currently expected by the market.

We believe that a fair degree of pessimism has now been priced into REITs, including the possibility of some decline in property asset values. We believe REITs, on the whole, are attractively valued, with many trading at compelling discounts (more than 20% in some cases) to their underlying net asset values, compared with their long-term average of a 5% premium to NAV. The private equity market continues to value REITs more aggressively than the public market, as evidenced by the continued privatizations of real estate companies.

From a property sector perspective we continue to favor apartments, and believe that recent events underscore our view that a downward trend in owner-occupied housing prices, coupled with tightening credit standards, are clear positives for the sector. In our view, uncertainty in the housing market should ultimately result in lower overall home ownership rates in the next five years, which in turn should benefit apartment owners. We also like the self-storage and office sectors on a stock-specific basis, and believe that the market has taken too negative a view of these sectors.

Expense Example (Unaudited)

As a shareholder of the fund, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs including management fees and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 01/01/07–06/30/07.

Actual Expenses

The first line of the table below provides information about actual account values and expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value January 1, 2007		Ending Account Value June 30, 2007		Expenses Paid During Period* January 1, 2007– June 30, 2007
Actual (–7.09% return)	$	1,000.00	$	929.10	$	4.40
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,020.23	$	4.61

* Expenses are equal to the Fund's annualized expense ratio of 0.92% multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

(the fund) was incorporated under the laws of the State of Maryland on April 26, 1991 and is registered under the Investment Company Act of 1940, as amended, as a nondiversified, open-end management investment company. The fund's investment objective is total return.

The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America (GAAP). The preparation of the financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Portfolio Valuation: Investments in securities that are listed on the New York Stock Exchange are valued, except as indicated below, at the last sale price reflected at the close of the New York Stock Exchange on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices for the day or, if no asked price is available, at the bid price.

Securities not listed on the New York Stock Exchange but listed on other domestic or foreign securities exchanges or admitted to trading on the National Association of Securities Dealers Automated Quotations, Inc. (Nasdaq) national market system are valued in a similar manner. Securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined as reflected on the tape at the close of the exchange representing the principal market for such securities.

Readily marketable securities traded in the over-the-counter market, including listed securities whose primary market is believed by Cohen & Steers Capital Management, Inc. (the advisor) to be over-the-counter, but excluding securities admitted to trading on the Nasdaq National List, are valued at the official closing prices as reported by Nasdaq, the National Quotation Bureau, or such other comparable sources as the Board of Directors deem appropriate to reflect their fair market value. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices for the day, or if no asked price is available, at the bid price. Where securities are traded on more than one exchange and also over-the-counter, the securities will generally be valued using the quotations the Board of Directors believes most closely reflect the value of such securities.

Securities for which market prices are unavailable, or securities for which the advisor determines that bid and/or asked price does not reflect market value, will be valued at fair value pursuant to procedures approved by the fund's Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems

16

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

appropriate. These may include recent transactions in comparable securities, information relating to the specific security and developments in the markets.

The fund's use of fair value pricing may cause the net asset value of fund shares to differ from the net asset value that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Short-term debt securities, which have a maturity date of 60 days or less, are valued at amortized cost, which approximates value.

Security Transactions and Investment Income: Security transactions are recorded on trade date. Realized gains and losses on investments sold are recorded on the basis of identified cost. Interest income is recorded on the accrual basis. Discounts are accreted and premiums are amortized over the life of the respective securities. Dividend income is recorded on the ex-dividend date. The fund records distributions received in excess of income from underlying investments as a reduction of cost of investments and/or realized gain. Such amounts are based on estimates if actual amounts are not available and actual amounts of income, realized gain and return of capital may differ from the estimated amounts. The fund adjusts the estimated amounts of the components of distributions (and consequently its net investment income) as an increase to unrealized appreciation/(depre ciation) and realized gain/(loss) on investments as necessary once the issuers provide information about the actual composition of the distributions.

Dividends and Distributions to Shareholders: Dividends from net investment income and capital gain distributions are determined in accordance with U.S. federal income tax regulations, which may differ from GAAP. Dividends from net investment income are declared and paid quarterly. Net realized capital gains, unless offset by any available capital loss carryforward, are distributed to shareholders annually. Dividends and distributions to shareholders are recorded on the ex-dividend date and are automatically reinvested in full and fractional shares of the fund based on the net asset value per share at the close of business on the ex-dividend date unless the shareholder has elected to have them paid in cash.

Distributions paid by the fund are subject to recharacterization for tax purposes. Based upon the results of operations for the six months ended June 30, 2007, the advisor considers it likely that a portion of the dividends will be reclassified to return of capital and distributions of net realized capital gains upon the final determination of the fund's taxable income for the year.

Federal Income Taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interest of the shareholders, by complying with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies, and by distributing substantially all of its taxable earnings to its shareholders. Accordingly, no provision for federal income or excise tax is necessary.

Note 2. Investment Advisory and Administration Fees and Other Transactions with Affiliates

Investment Advisory Fees: The advisor serves as the fund's investment advisor pursuant to an investment advisory agreement (the advisory agreement). Under the terms of the advisory agreement, the advisor provides the fund with the day-to-day investment decisions and generally manages the fund's investments in accordance with the stated policies of the fund, subject to the supervision of the fund's Board of Directors. For the services provided to the fund, the advisor receives a fee, accrued daily and paid monthly, at the annual rate of 0.85% for the first $1.5 billion and 0.75% thereafter of the average daily net assets of the fund.

Administration Fees: The fund has entered into an administration agreement with the advisor under which the advisor performs certain administrative functions for the fund and receives a fee, accrued daily and paid monthly, at the annual rate of 0.02% of the fund's average daily net assets. For the six months ended June 30, 2007, the fund paid the advisor $371,730 in fees under this administration agreement. Additionally, the fund has retained State Street Bank and Trust Company as sub-administrator under a fund accounting and administration agreement.

Directors' and Officers' Fees: Certain directors and officers of the fund are also directors, officers, and/or employees of the advisor. The fund does not pay compensation to any affiliated directors and officers except for the Chief Compliance Officer, who received $18,880 from the fund for the six months ended June 30, 2007.

Note 3. Purchases and Sales of Securities

Purchases and sales of securities, excluding short-term investments, for the six months ended June 30, 2007, totaled $1,226,396,412 and $1,400,201,449, respectively.

^a  The fund may charge a 1% redemption fee on shares sold within six months of the time of purchase.

Note 6. Borrowings

The fund, in conjunction with other Cohen & Steers funds, is a party to a $150,000,000 syndicated credit agreement (the credit agreement) with State Street Bank and Trust Company, as administrative agent and operations agent, and the lenders identified in the credit agreement, which expires December 2007. The fund pays a commitment fee of 0.10% per annum on its proportionate share of the unused portion of the credit agreement.

During the six months ended June 30, 2007, the fund did not utilize the line of credit.

Note 7. Other

In the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is dependent on claims that may be made against the fund in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote.

Note 8. New Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. An assessment of the fund's tax positions has been made and it has been determined that there is no impact to the fund's financial statements.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the fund's financial statements.

Note 9. Subsequent Event

Effective September 28, 2007, the redemption fee charged by the fund will be 2% on shares redeemed or exchanged within 60 days of the time of purchase. Please see the prospectus for further details.

APPROVAL OF INVESTMENT ADVISORY AGREEMENT

The board of directors of the fund, including a majority of the directors who are not parties to the fund's Management Agreement, or interested persons of any such party ("Independent Directors"), has the responsibility under the 1940 Act to approve the fund's Management Agreement for its initial two year term and its continuation annually thereafter at a meeting of the board called for the purpose of voting on the approval or continuation. At a meeting held in person on March 6, 2007, the Management Agreement was discussed and was unanimously continued for a one-year term by the fund's board, including the Independent Directors. The Independent Directors were represented by independent counsel who assisted them in their deliberations during the meeting and executive session.

In considering whether to continue the Management Agreement, the board reviewed materials provided by the fund's investment manager (the "Investment Manager") and fund counsel which included, among other things, fee, expense and performance information compared to peer funds ("Peer Funds") prepared by an independent data provider, supplemental performance and summary information prepared by the Investment Manager, sales and redemption data for the fund and memoranda outlining the legal duties of the board. The board also spoke directly with representatives of the independent data provider and met with investment advisory personnel. In addition, the board considered information provided from time to time by the Investment Manager throughout the year at meetings of the board, including presentations by portfolio managers relating to the investment performance of the fund and the investment strategies used in pursuing the fund's objective. In p articular, the board considered the following:

(i) The nature, extent and quality of services to be provided by the Investment Manager: The board reviewed the services that the Investment Manager provides to the fund, including, but not limited to, making the day-to-day investment decisions for the fund, and generally managing the fund's investments in accordance with the stated policies of the fund. The board also discussed with officers and portfolio managers of the fund the amount of time the Investment Manager dedicates to the fund and the types of transactions that were being done on behalf of the fund. Additionally, the board took into account the services provided by the Investment Manager to its other funds, including those that invest substantially in real estate securities and have investment objectives and strategies similar to the fund.

The board next considered the education, background and experience of the Investment Manager's personnel, noting particularly that the favorable history and reputation of the portfolio managers for the fund, has had, and would likely continue to have, a favorable impact on the success of the fund. The board further noted the Investment Manager's ability to attract quality and experienced personnel. After consideration of the above factors, among others, the board concluded that the nature, quality and extent of services provided by the Investment Manager are adequate and appropriate.

22

COHEN & STEERS REALTY SHARES, INC.

(ii) Investment performance of the fund and the Investment Manager: The board considered the investment performance of the fund compared to Peer Funds and compared to a relevant benchmark. The board noted that the fund outperformed the Peer Funds and benchmark during the one, three and five-year periods. In particular, the board noted that among the Peer Funds, the fund ranked fifth in total returns for the one-year period, third in total returns for the three-year period and fourth in total returns for the five-year period, placing the fund in the first quartile among its Peer Funds over all periods. The board also considered the Investment Manager's performance in managing other real estate funds. The board then determined that fund performance, in light of all considerations noted above, was satisfactory.

(iii) Cost of the services to be provided and profits to be realized by the Investment Manager from the relationship with the fund: Next, the board considered the advisory fees and administrative fees payable by the fund, as well as total expense ratios. As part of their analysis, the board gave substantial consideration to the fee and expense analyses provided by the independent data provider. The board noted that the advisory fee was above the median for the Peer Funds and that the total expense ratio (on a gross and net basis) was below the Peer Fund median and in the second quartile versus the Peer Funds. The board further noted that the administrative fees payable by the fund were below the Peer Fund median. In light of the considerations above, the board concluded that the fund's expense structure was competitive in the peer group.

The board also reviewed information regarding the profitability to the Investment Manager of its relationship with the fund. The board considered the level of the Investment Manager's profits and whether the profits were reasonable for the Investment Manager. The board took into consideration other benefits to be derived by the Investment Manager in connection with the Management Agreement, noting particularly the research and related services, within the meaning of Section 28(e) of the Securities Exchange Act of 1934, as amended, that the Investment Manager receives by allocating the fund's brokerage transactions. The board also considered the fees received by the Investment Manager under the Administration Agreement, but noted the significant services received, such as operational services and furnishing office space and facilities for the fund, and providing persons satisfactory to the board to serve as officers of the fund, and that thes e services were beneficial to the fund. The directors concluded that the profits realized by the Investment Manager from its administrative relationship with the fund were reasonable and consistent with fiduciary duties.

(iv) The extent to which economies of scale would be realized as the fund grows and whether fee levels would reflect such economies of scale: The board noted that the fund's advisory fee schedule does not contain any breakpoints. The board considered the fund's asset size and determined that there were not at this time significant economies of scale that were not being shared with stockholders.

(v) Comparison of services rendered and fees paid to those under other investment advisory contracts, such as contracts of the same and other investment advisers or other clients: As discussed above in (i) and (iii), the board compared both the services rendered and the fees paid under the Management Agreement to those under

23

COHEN & STEERS REALTY SHARES, INC.

other investment advisory contracts of other investment advisers managing Peer Funds. The board was also provided with an industry study analyzing differences between funds and institutional accounts and the services and fees associated with each and compared the services rendered, fees paid and profitability under the Management Agreement to the Investment Manager's other advisory contracts with institutional and other clients with similar investment mandates. The board determined that on a comparative basis the fees under the Management Agreement were reasonable in relation to the services provided.

No single factor was cited as determinative to the decision of the board. Rather, after weighing all of the considerations and conclusions discussed above, the board, including the Independent Directors, unanimously approved the continuation of the Management Agreement.
