A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Investment Portfolios, Core Value Portfolio, covering the 12-month period from January 1, 2010, through December 31, 2010.

Although 2010 proved to be a volatile year for stocks, the reporting period ended with a sustained market rally that produced above-average returns across most market-cap segments for the calendar year. Investors’ early concerns regarding sovereign debt issues in Europe and stubbornly high unemployment in the United States later gave way to optimism that massive economic stimulus programs, robust growth in the world’s emerging markets, a strong holiday retail season and rising corporate earnings signaled better economic times ahead.

We are aware that stocks have recently reached higher valuations, and that any new economic setbacks could result in market volatility as investors adjust their expectations. Nonetheless, we see value in many segments of the equity market. For example, investors in volatile markets may turn to high-quality stocks of U.S. companies with track records of consistent growth in a variety of economic climates, and international equities could benefit from a declining U.S. dollar and potentially higher growth opportunities abroad.With 2011 now upon us, we suggest talking to your financial advisor, who can help you identify potential opportunities and suggest strategies suitable for your individual needs in today’s market environment.

For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Thank you for your continued confidence and support.

Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2010, through December 31, 2010, as provided by Brian Ferguson, Portfolio Manager

Fund and Market Performance Overview

For the 12-month period ended December 31, 2010, Dreyfus Investment Portfolios, CoreValue Portfolio, produced a total return of 13.21% for its Initial shares, and its Service shares produced a total return of 12.93%.¹ In comparison, the fund’s benchmark, the Russell 1000Value Index (the “Index”), produced a total return of 15.51% for the same period.²

Despite heightened volatility over the first half of 2010, a later rally stemming from greater economic clarity enabled the stock market to achieve double-digit gains for the year.The fund produced lower returns than its benchmark, primarily due to shortfalls in the information technology, consumer discretionary and financials sectors.

The Fund’s Investment Approach

The fund seeks long-term growth of capital, with current income as a secondary objective. To pursue its goal, the fund invests primarily in large-cap companies that are considered undervalued based on traditional measures, such as price-to-earnings ratios.When choosing stocks, we use a “bottom-up” stock selection approach, focusing on individual companies, rather than a “top-down” approach that forecasts market trends. We also focus on a company’s relative value, financial strength, business momentum and likely catalysts that could ignite the stock price.

Waning Economic Concerns Fueled a Market Rally

Soon after the start of 2010, a number of new developments shook investors’ confidence in ongoing global and domestic economic recoveries. Europe was roiled by a sovereign debt crisis that led to austerity measures throughout the region, and mixed housing and employment data in the United States weighed on already mild domestic growth.As a result, U.S. stocks generally declined over the first half of the year.

However, investors’ economic concerns may have been overblown.

Corporate earnings over the second half of the year exceeded analysts’

expectations, commodity prices climbed amid robust demand from the world’s emerging markets, and the U.S. and global economies remained on mildly upward trajectories. The resolution of midterm elections and new stimulative programs by the Federal Reserve Board also boosted investor sentiment. However, growth-oriented stocks produced higher returns, on average, than value stocks in 2010.

Security Selections Dampened Returns in Some Sectors

Although the fund participated to a substantial degree in the stock market’s 2010 gains, disappointing security selections in certain market segments prevented it from matching the benchmark’s results. In the information technology sector, Cisco Systems struggled due to weakness in its European and U.S. public sector markets, and personal computer maker Hewlett-Packard declined when its CEO resigned abruptly. Software giant Microsoft lagged market averages as the company appeared to miss opportunities to capitalize on the trend toward “cloud computing,” in which data and a pplications are maintained and accessed over the Internet.

The fund’s consumer discretionary holdings also fell short of their respective benchmark components, as we favored media companies that create programming content over better performing content distributors. In addition, retailers Best Buy and Staples struggled amid changing consumer spending patterns and a lack of exciting new products.Among financial stocks, Bank of America, JPMorgan Chase & Co. and Morgan Stanley fared relatively poorly due to intensifying regulatory pressures, slower mergers-and-acquisitions activity and lower trading volumes. Relatively light exposure to real estate investment trusts also weighed on the fund’s relative performance.

On a more positive note, the fund focused successfully on industrial companies—including Caterpillar and Eaton Corp.—that have benefited from strong demand for the equipment and materials used in infrastructure construction in the world’s emerging markets. The materials sector also contained a number of top performers, including Freeport McMoRan Copper & Gold, which gained value along with underlying commodity prices.An underweighted position in the health care sector helped the fund avoid the brunt of weakness stemming from large pharmaceutical companies, such as Johnson & Johnson, that strug-

gled with pricing pressures and a dearth of new products in their development pipelines. Instead, we emphasized service companies such as drug distributor AmerisourceBergen, which benefited from greater demand for generic medicines.

Positioned for a More Selective Market Environment

We expect the U.S. economic recovery to persist in 2011. Greater economic and political clarity in the wake of U.S. midterm elections—including fiscal stimulus from a cut in payroll taxes and extension of Bush-era tax cuts—may help convince business leaders to deploy some of their massive cash reserves for mergers-and-acquisitions, stock buybacks and other productive uses. However, a number of economic headwinds remain, including high levels of unemployment and troubled housing markets.

We expect investors to become more selective in this environment, favoring companies that can grow consistently in a slowly expanding economy. Therefore, we have maintained an overweighted position among attractively valued media companies with solid business fundamentals. Conversely, the fund holds relatively few utilities, which generally do not meet our value-oriented investment criteria.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Investment Portfolios (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company operating as a series company currently offering four series, including the Core Value Portfolio (the “fund”). The fund is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies.The fund is a diversified series.The fund’s investment objective is to seek long-term capital growth. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold without a sales charge. The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Initial and Service. Each class of shares has identical rights and privileges, except with respect to the distribution plan and the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for

The Fund 19

NOTES TO FINANCIAL STATEMENTS (continued)

SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions.Actual results could differ from those estimates.

The Company enters into contracts that contain a variety of indemnifications.The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market),but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Trustees. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant ADRs and futures contracts. For other securities that are fair valued by the Board of Trustees, certain factors may be considered such as: funda-

20

mental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold and public trading in similar securities of the issuer or comparable issuers.

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Fund 21

NOTES TO FINANCIAL STATEMENTS (continued)

The following is a summary of the inputs used as of December 31, 2010 in valuing the fund’s investments:

		Level 2—Other	Level 3—
	Level 1—	Significant	Significant
	Unadjusted	Observable	Unobservable

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about FairValue Measurements”. The portions of ASU No. 2010-06 which require reporting entities to prepare new disclosures surrounding amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3 have been adopted by the fund. No significant transfers between Level 1 or Level 2 fair value measurements occurred at December 31, 2010. The remaining portion of ASU No. 2010-06 requires reporting entities to make new disclosures about information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. These new and re vised disclosures are required to be implemented for fiscal years beginning after December 15, 2010. Management is currently evaluating the impact that the adoption of this remaining portion of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

22

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager, U.S. Government and Agency securities or letters of credit.The fund is entitled to receive all income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of r ights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended December 31, 2010,The Bank of New York Mellon earned $43 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” in the Act.

The fund may invest in shares of certain affiliated investment companies also advised or managed by Dreyfus. Investments in affiliated investment companies for the period ended December 31, 2010 were as follows:

The Fund 23

NOTES TO FINANCIAL STATEMENTS (continued)

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) 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 interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended December 31, 2010, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

Each of the tax years in the four-year period ended December 31, 2010 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At December 31, 2010, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $327,567, accumulated capital losses $7,784,073 and unrealized appreciation $5,124,794.

In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended December 31, 2010, the fund did not borrow under the Facilities.

NOTE 3—Investment Advisory Fee and Other Transactions With Affiliates:

(a) Pursuant to an investment advisory agreement with the Manager, the investment advisory fee is computed at the annual rate of .75% of the value of the fund’s average daily net assets and is payable monthly.

(b) Under the Distribution Plan (the “Plan”) adopted pursuant to Rule 12b-1 under the Act, Service shares pay the Distributor for distributing their shares, for servicing and/or maintaining Service shares’ shareholder accounts and for advertising and marketing for Service shares.The Plan provides for payments to be made at an annual rate of .25% of the value of the Service shares’ average daily net assets.The Distributor may make payments to Participating Insurance Companies and to brokers and dealers acting as principal underwriter for their variable insurance prod-ucts.The fees payable under the Plan are payable without regard to actual expenses incurred.

INFORMATION ABOUT THE REVIEW
AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited)

At a meeting of the Board of Trustees of the Company held on July 14 and 15, 2010, the Board considered the re-approval for an annual period (through August 31, 2011) of the fund’s Investment Advisory Agreement (the “Management Agreement”) with the Manager, pursuant to which the Manager provides the fund with investment advisory and administrative services.The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Company, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent and Quality of Services Provided to the Fund.The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement.The Manager’s representatives reviewed the fund’s distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each.The Board noted that the fund’s shares are offered only to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies. The Manager’s representatives noted the diversity of distribution among the funds in the Dreyfus fund complex, an d the Manager’s corresponding need for broad, deep and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including that of the fund.The Manager also provided the number of separate accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered the Manager’s research and portfolio management capabilities and that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements. The Board members also considered the Manager’s extensive administrative, accounting and compliance infrastructure.

30

The Board also considered the Manager’s brokerage policies and practices, the standards applied in seeking best execution and the Manager’s policies and practices regarding soft dollars.

Comparative Analysis of the Fund’s Performance and Investment Advisory Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to a group of large-cap value funds underlying variable insurance products (the “Performance Group”) and to a larger universe of funds, consisting of all large-cap value funds underlying variable insurance products (the “Performance Universe”), selected and provided by Lipper, Inc., an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below). The Board members discussed the results of the comparisons for various periods ended May 31, 2010. The Board members not ed that the fund’s total return performance was above the Performance Group and Performance Universe medians for the 4-year and 5-year periods, and was at or below the Performance Group and Performance Universe medians for all other periods. In addition, the Board members noted that the fund’s total return performance was slightly lower than the Performance Group median for the 1-year period. Representatives of the Manager also noted that the fund’s portfolio is comprised of high-quality investments and that during the recent reporting period these investments had underperformed lower-quality investments. The Manager also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s investment advisory fee and expense ratio and reviewed the range of investment advisory fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper.The Board members

The Fund 31

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

noted that the actual investment advisory fee and total expense ratio of the fund’s Initial shares (which are not subject to a Rule 12b-1 plan) were higher than the Expense Group and Expense Universe medians. They also noted that the fund’s contractual investment advisory fee was at the Expense Group median. In addition, the Board noted that the total expense ratio of the fund’s Service shares (which are subject to a Rule 12b-1 plan) was higher than the Expense Group and Expense Universe medians.

Representatives of the Manager reviewed with the Board members the management fees paid by other accounts managed by the Manager or its affiliates with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”).The Manager’s representatives explained the nature of the Similar Accounts and the differences in providing services to such Similar Accounts as compared to managing and providing services to the fund. Representatives of the Manager noted that the Manager or its affiliates do not manage other mutual funds with similar investment objectives, policies and strategies as the fund underlying variable insurance products and included within the fund’s Lipper category. The Board analyzed the differences in fees paid to the Manager and discussed the relationship of the fees paid in light of the services provided. The Board members considered the relevance of the f ee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s investment advisory fee.

Analysis of Profitability and Economies of Scale.The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board previously had been provided with information prepared by an independent consulting firm regarding the Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund com-plex.The Board members also had been informed that the methodology had been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of

32

scale might emerge in connection with the management of the fund. The Board members evaluated the profitability analysis in light of the relevant circumstances for the fund, and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors.The Board members also considered potential benefits to the Manager from acting as investment adviser to the fund, including any soft dollar arrangements with respect to trading the fund’s investments.

It was noted that the Board members should consider the Manager’s profitability with respect to the fund as part of their evaluation of whether the fee under the Management Agreement bears a reasonable relationship to the mix of services provided by the Manager, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund’s assets had been decreasing, the possibility that the Manager may have realized any economies of scale would be less. It also was noted that the Manager did not realize a profit on the fund’s operations.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

• The Board concluded that the nature, extent and quality of the ser- vices provided by the Manager are adequate and appropriate.

• The Board expressed its concern about the fund’s relative underper- formance, but noted the Manager’s explanation of factors affecting performance and determined to closely monitor performance.

• The Board concluded that the fee paid by the fund to the Manager was reasonable in light of the services provided, comparative perfor- mance, expense and investment advisory fee information, costs of the services provided and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.

The Fund 33

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

• The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of the fund had been adequately considered by the Manager in con- nection with the investment advisory fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the Management Agreement was in the best interests of the fund and its shareholders.

Dreyfus Investment Portfolios,
MidCap Stock Portfolio

The Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Investment Portfolios, MidCap Stock Portfolio, covering the 12-month period from January 1, 2010, through December 31, 2010.

Although 2010 proved to be a volatile year for stocks, the reporting period ended with a sustained market rally that produced above-average returns across most market-cap segments for the calendar year. Investors’ early concerns regarding sovereign debt issues in Europe and stubbornly high unemployment in the United States later gave way to optimism that massive economic stimulus programs, robust growth in the world’s emerging markets, a strong holiday retail season and rising corporate earnings signaled better economic times ahead.

We are aware that stocks have recently reached higher valuations, and that any new economic setbacks could result in market volatility as investors adjust their expectations. Nonetheless, we see potential value in many segments of the equity market. For example, investors in volatile markets may turn to high-quality stocks of U.S. companies with track records of consistent growth in a variety of economic climates, and international equities could benefit from a declining U.S. dollar and potentially higher growth opportunities abroad.With 2011 now upon us, we suggest talking to your financial advisor, who can help you identify potential opportunities and suggest strategies suitable for your individual needs in today’s market environment.

For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Thank you for your continued confidence and support.

Jonathan R. Baum
Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2010, through December 31, 2010, as provided by Patrick Slattery, Portfolio Manager

Fund and Market Performance Overview

For the 12-month period ended December 31, 2010, Dreyfus Investment Portfolios, MidCap Stock Portfolio’s Initial shares produced a total return of 27.10%, and its Service shares produced a total return of 26.94%.¹ In comparison, the fund’s benchmark, the Standard & Poor’s MidCap 400 Index (the “S&P 400 Index”), produced a total return of 26.64% for the same period.²

Equity prices were driven higher in 2010 by improving corporate earnings and revenues, as well as renewed confidence late in the year that the U.S. economy was emerging from recession. Small- and midcap stocks performed particularly well in this environment. The fund produced higher returns than its benchmark, primarily due to the success of our stock selection process across most of the market sectors represented in the S&P 400 Index.

The Fund’s Investment Approach

The fund seeks investment results that are greater than the total return performance of publicly traded common stocks of medium-size domestic companies in the aggregate, as represented by the S&P 400 Index.To pursue this goal, the fund normally invests at least 80% of its assets in stocks of midsize companies.The fund invests in growth and value stocks, which are chosen through a disciplined investment process that combines computer modeling techniques, fundamental analysis and risk management. Consistency of returns compared to the S&P 400 Index is a primary goal of the investment process.

Economic Developments Sparked Heightened Volatility

Throughout 2010, the U.S. economy continued to emerge from recession at a slow but steady pace. However, investor sentiment proved volatile in light of unsettling global developments and uncertainty regarding the recovery’s sustainability. After generally positive economic data sent stocks higher from February through late April 2010, the market retreated on news of an intensifying sovereign debt crisis in

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

Europe. During the summer, stubbornly high levels of U.S. unemployment and troubled housing markets, along with growing inflationary pressures in China, constrained equity prices near their lows for the year. However, continuing U.S. economic improvement in the fall led to a growing consensus that a return to recession was unlikely, and political developments following the midterm elections provided greater clarity regarding U.S. economic and tax policies. As investor confidence rose, stocks climbed sharply during the fourth quarter of 2010.

Quantitative Factors Proved Broadly Positive

A broad range of the quantitative modeling factors that drive the fund’s stock selection process enhanced performance during the reporting period. Behavioral factors, such as price momentum, and quality-related factors, such as earnings quality, contributed strongly to the fund’s relative outperformance. Value-related factors generated more volatile results, particularly during times of market weakness, but generally added to returns for the year as a whole.

Health Care and Industrials Sectors Led Performance

Investments in health care companies produced some of the fund’s better returns compared to the benchmark. OSI Pharmaceuticals was acquired by Astellas Pharma at a significant premium to its then-prevailing stock price. Endo Pharmaceuticals Holdings rose on the strength of favorable quarterly reports and positive market reaction to the company’s agreement to acquire generic drug manufacturer Qualitest Pharmaceuticals. Such gains overshadowed results from health care holdings that failed to keep pace with the sector’s advance, such as biotechnology product maker Techne.

The fund generated relatively robust returns in other areas as well. Strong gains among industrial holdings, such as diversified machinery parts manufacturer Timken, more than made up for the underperfor-mance of others, such as truck maker Oshkosh.The fund also produced strong results in the commercial services sector by holding outperforming IT services providers such as Gartner, and with the exception of services outsourcing provider Computer Sciences, avoided most of the sector’s weaker performers. Top holdings in other areas included fashion accessory designer Fossil and aftermarket automobile parts maker Advance Auto Parts.

4

The fund generally kept pace with the market’s gains in the technology sector. Enterprise software developer Sybase rose sharply on news of a takeover offer, while equipment maker F5 Networks and electrical components manufacturer Vishay Intertechnology both delivered strong financial results. On the other hand, computer wholesaler Tech Data and communications equipment maker CommScope both underperformed early in the reporting period after providing weaker-than-expected guidance.

Utilities proved to be the fund’s weakest sector. Several holdings, such as Constellation Energy Group and DPL, undermined the fund’s relative performance.

Continued Commitment to Our Disciplined Process

We are pleased that, as of the end of the reporting period, prevailing market conditions appeared to favor our disciplined stock selection process. Our consistent commitment to this process across the full range of market cycles remains the cornerstone of our investment approach.

Equity funds are subject generally to market, market sector, market liquidity, issuer and investment
style risks, among other factors, to varying degrees, all of which are more fully described in the
fund’s prospectus.
Stocks of midcap companies often experience sharper price fluctuations than stocks of
large-cap companies.
The fund is only available as a funding vehicle under variable life insurance policies or variable
annuity contracts issued by insurance companies. Individuals may not purchase shares of the fund
directly.A variable annuity is an insurance contract issued by an insurance company that enables
investors to accumulate assets on a tax-deferred basis for retirement or other long-term goals.

1 Total return includes reinvestment of dividends and any capital gains paid. Past performance is no
guarantee of future results. Share price and investment return fluctuate such that upon redemption,
fund shares may be worth more or less than their original cost.The fund’s performance does not
reflect the deduction of additional charges and expenses imposed in connection with investing in
variable insurance contracts, which will reduce returns. Return figures provided reflect the absorption of
certain fund expenses by The Dreyfus Corporation pursuant to an agreement in effect through
August 31, 2010. Had these expenses not been absorbed, the fund’s returns would have been lower.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Investment Portfolios (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company, operating as a series company currently offering four series, including the MidCap Stock Portfolio (the “fund”). The fund is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies.The fund is a diversified series.The fund’s investment objective is to seek investment results that are greater than the total return performance of publicly traded common stocks of medium-size domestic companies in the aggregate, as represented by the Standard & Poor’s MidCap 400 Index. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Me llon”), serves as the fund’s investment adviser.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold without a sales charge. The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Initial and Service. Each class of shares has identical rights and privileges, except with respect to the distribution plan, the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized

The Fund 21

NOTES TO FINANCIAL STATEMENTS (continued)

by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions.Actual results could differ from those estimates.

The Company enters into contracts that contain a variety of indemnifications.The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board ofTrustees. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and

22

other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Trustees, certain factors may be considered such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers.

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about FairValue Measurements”. The portions of ASU No. 2010-06 which require reporting entities to prepare new disclosures surrounding amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3 have been adopted by the fund. No significant transfers between Level 1 or Level 2 fair value measurements occurred at December 31, 2010. The remaining portion of ASU No. 2010-06 requires reporting entities to make new disclosures about information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. These new and re vised disclosures are required to be implemented for fiscal years beginning after December 15, 2010. Management is currently evaluating the impact that the adoption of this remaining portion of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

24

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager, U.S. Government and Agency securities or letters of credit.The fund is entitled to receive all income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of r ights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended December 31, 2010, The Bank of New York Mellon earned $6,487 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” in the Act.

The fund may invest in shares of certain affiliated investment companies also advised or managed by Dreyfus. Investments in affiliated investment companies for the period ended December 31, 2010 were as follows:

The Fund 25

NOTES TO FINANCIAL STATEMENTS (continued)

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) 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 interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended December 31, 2010, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

Each of the tax years in the four-year period ended December 31, 2010 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At December 31, 2010, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $791,814, accumulated capital losses $58,430,851 and unrealized appreciation $24,956,945.

The accumulated capital loss carryover is available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to December 31, 2010. If not applied, $12,514,855 of the carryover expires in fiscal 2016 and $45,915,996 expires in fiscal 2017.

26

The tax character of distributions paid to shareholders during the fiscal periods ended December 31, 2010 and December 31, 2009 were as follows: ordinary income $1,510,101 and $1,940,578, respectively.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in a $225 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing.

The average amount of borrowings outstanding under the Facilities during the period ended December 31, 2010 was approximately $15,900, with a related weighted average annualized interest rate of 1.52%.

NOTE 3—Investment Advisory Fee and Other Transactions With Affiliates:

(a) Pursuant to an investment advisory agreement with the Manager, the investment advisory fee is computed at the annual rate of .75% of the value of the fund’s average daily net assets and is payable monthly.

The Manager had agreed, from March 1, 2010 to August 31, 2010, to waive receipt of its fees and/or assume the expenses of the fund so that the expenses of neither class exclusive of taxes, brokerage fees, interest on borrowings, commitment fees and extraordinary expenses, do not exceed .90% of the value of the average daily net assets of such class. During the period ended December 31, 2010, the Manager waived $20,350 for Service shares, pursuant to the undertaking.

(b) Under the Distribution Plan (the “Plan”) adopted pursuant to Rule 12b-1 under the Act, Service shares pay the Distributor for dis-

The Fund 27

NOTES TO FINANCIAL STATEMENTS (continued)

tributing their shares, for servicing and/or maintaining Service shares’ shareholder accounts and for advertising and marketing for Service shares.The Plan provides for payments to be made at an annual rate of .25% of the value of the Service shares’ average daily net assets. The Distributor may make payments to participating insurance companies and to brokers and dealers acting as principal underwriter for their variable insurance products. The fees payable under the Plan are payable without regard to actual expenses incurred. During the period ended December 31, 2010, Service shares were charged $43,370 pursuant to the Plan.

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

Shareholders and Board of Trustees

Dreyfus Investment Portfolios, MidCap Stock Portfolio

Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement.We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting.Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting p rinciples used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2010 by correspondence with the custodian and oth-ers.We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Dreyfus Investment Portfolios, MidCap Stock Portfolio at December 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the indicated years, in conformity with U.S. generally accepted accounting principles.

INFORMATION ABOUT THE REVIEW AND
APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT (Unaudited)

At a meeting of the Board of Trustees of the Company held on July 14 and 15, 2010, the Board considered the re-approval for an annual period (through August 31, 2011) of the fund’s Investment Advisory Agreement (the “Management Agreement”) with the Manager, pursuant to which the Manager provides the fund with investment advisory and administrative services.The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Company, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent and Quality of Services Provided to the Fund.The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement.The Manager’s representatives reviewed the fund’s distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each.The Board noted that the fund’s shares are offered only to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies. The Manager’s representatives noted the diversity of distribution among the funds in the Dreyfus fund complex, an d the Manager’s corresponding need for broad, deep and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including that of the fund.The Manager also provided the number of separate accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered the Manager’s research and portfolio management capabilities and that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements. The Board members also considered the Manager’s extensive administrative, accounting and compliance infrastructure. The Board

32

also considered the Manager’s brokerage policies and practices, the standards applied in seeking best execution and the Manager’s policies and practices regarding soft dollars.

Comparative Analysis of the Fund’s Performance and Investment Advisory Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to a group of mid-cap core funds underlying variable insurance products (the “Performance Group”) and to a larger universe of funds consisting of all mid-cap core funds underlying variable insurance products (the “Performance Universe”), selected and provided by Lipper, Inc., an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below).The Board members discussed the results of the comparisons for various periods ended May 31, 2010. The Board members noted that the fund’s total return performance was below the Performance Group and Performance Universe medians for all periods, except for the 1-year period of the Performance Group where the fund’s performance was at the median. Representatives of the Manager reminded the Board of the changes made to portfolio management’s investment process for the fund and noted the fund’s performance had improved more recently.The Manager also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s investment advisory fee and expense ratio and reviewed the range of investment advisory fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper.The Board members noted that the actual and contractual investment advisory fees and total expense ratio of the fund’s Initial shares (which are not subject to a Rule 12b-1 plan) were lower than the Expense Group medians.They noted

The Fund 33

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

that the fund’s actual investment advisory fee was higher than the Expense Universe median, but that the fund’s total expense ratio was lower than the Expense Universe median. In addition, the Board noted that the total expense ratio of the fund’s Service shares (which are subject to a Rule 12b-1 plan) was higher than the Expense Group median and lower than the Expense Universe median.The Board also considered the current fee waiver and expense reimbursement arrangement undertaken by the Manager.

Representatives of the Manager reviewed with the Board members the investment advisory fees paid by other accounts managed by the Manager or its affiliates with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”).The Manager’s representatives explained the nature of the Similar Accounts and the differences in providing services to such Similar Accounts as compared to managing and providing services to the fund. Representatives of the Manager noted that the Manager or its affiliates do not manage other mutual funds with similar investment objectives, policies and strategies as the fund underlying variable insurance products and included within the fund’s Lipper category.The Board analyzed the differences in fees paid to the Manager and discussed the relationship of the fees paid in light of the services provided.The Board members considered the relevance o f the fee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s investment advisory fee.

Analysis of Profitability and Economies of Scale.The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board previously had been provided with information prepared by an independent consulting firm regarding the Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund com-plex.The Board members also had been informed that the methodology had been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of

scale might emerge in connection with the management of the fund. The Board members evaluated the profitability analysis in light of the relevant circumstances for the fund, and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors.The Board members also considered potential benefits to the Manager from acting as investment adviser to the fund, including any soft dollar arrangements with respect to trading the fund’s investments.

It was noted that the Board members should consider the Manager’s profitability with respect to the fund as part of their evaluation of whether the fee under the Management Agreement bears a reasonable relationship to the mix of services provided by the Manager, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund’s assets had been decreasing, the possibility that the Manager may have realized any economies of scale would be less. It also was noted that the Manager did not realize a profit on the fund’s operations.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

• The Board concluded that the nature, extent and quality of the ser- vices provided by the Manager are adequate and appropriate.

• The Board was concerned with the fund’s performance, but noted changes made to portfolio management’s investment process for the fund and the fund’s improved short-term performance.

• The Board concluded that the fee paid by the fund to the Manager was reasonable in light of the services provided, comparative perfor- mance, expense and investment advisory fee information (including the fee waiver and expense reimbursement arrangement), costs of the services provided and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

• The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of the fund had been adequately considered by the Manager in con- nection with the investment advisory fee rate charged to the fund, and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the Management Agreement was in the best interests of the fund and its shareholders.

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Investment Portfolios, Small Cap Stock Index Portfolio, covering the 12-month period from January 1, 2010, through December 31, 2010.

Although 2010 proved to be a volatile year for stocks, the reporting period ended with a sustained market rally that produced above-average returns across most market-cap segments for the calendar year. Investors’ early concerns regarding sovereign debt issues in Europe and stubbornly high unemployment in the United States later gave way to optimism that massive economic stimulus programs, robust growth in the world’s emerging markets, a strong holiday retail season and rising corporate earnings signaled better economic times ahead.

We are aware that stocks have recently reached higher valuations, and that any new economic setbacks could result in market volatility as investors adjust their expectations. Nonetheless, we see potential value in many segments of the equity market. For example, investors in volatile markets may turn to high-quality stocks of U.S. companies with track records of consistent growth in a variety of economic climates, and international equities could benefit from a declining U.S. dollar and potentially higher growth opportunities abroad.With 2011 now upon us, we suggest talking to your financial advisor, who can help you identify potential opportunities and suggest strategies suitable for your individual needs in today’s market environment.

For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2010, through December 31, 2010, as provided by Thomas J. Durante, Karen Q.Wong and Richard A. Brown, Portfolio Managers

Fund and Market Performance Overview

For the 12-month period ended December 31, 2010, Dreyfus Investment Portfolios, Small Cap Stock Index Portfolio produced a total return of 25.83%.¹ In comparison, the fund’s benchmark, the Standard & Poor’s SmallCap 600 Index (the “S&P 600 Index”) produced a 26.31% return for the same period.^2,3

Despite heightened market volatility over the first half of the year, stocks generally ended 2010 with substantial gains as investors gained confidence in the economic recovery. Small-cap stocks generally produced higher returns than their large-cap counterparts. The difference in returns between the fund and its benchmark was primarily due to the fund’s sampling strategy, transaction costs and fund operating expenses.

The Fund’s Investment Approach

The fund seeks to match the performance of the S&P 600 Index by investing in a representative sample of the stocks included in the S&P 600 Index, and in futures whose performance is tied to the S&P 600 Index. The fund’s investments are selected by a “sampling” process based on market capitalization, industry representation and other means.The fund expects to invest in approximately 500 or more of the stocks in the S&P 600 Index.

A Late Market Rally Erased Earlier Losses

The year 2010 began in the midst of an economic recovery as improved manufacturing activity and rising corporate earnings helped boost confidence among businesses, consumers and investors. The stock market generally rallied, and investors continued to favor lower-quality stocks, including those of small-cap companies that had been severely punished in the previous downturn.

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

In the spring, however, investor sentiment deteriorated when several new global developments weighed heavily on the equity markets. Greece and, later, Ireland found themselves unable to refinance heavy debt loads, part of a sovereign debt crisis that led to the adoption of austerity budgets among governments throughout the European Union.A catastrophic oil spill in the Gulf of Mexico threatened economic activity along the U.S. Gulf Coast and the prospects of deep-sea oil drillers. Meanwhile, stubbornly high U.S. unemployment and troubled housing markets continued to undermine an already sluggish domestic economic rebound.

It became clearer over the summer that investors’ economic concerns may have been overblown. Corporate earnings generally exceeded analysts’ expectations, commodity prices climbed amid robust demand from the emerging markets, mergers-and-acquisitions activity increased, and the U.S. and global economies remained on upward trajectories.

Throughout the reporting period, the Federal Reserve Board (the “Fed”) made it clear that it would continue to employ all available tools to stimulate the economy, including maintaining the overnight federal funds rate in a historically low range between 0.00% and 0.25%. In August, the Fed announced plans for a second round of quantitative easing involving the purchase of $600 billion of U.S.Treasuries.The Fed’s announcement sparked a market rally that persisted through year-end. The resolution of uncertainty regarding U.S. economic and tax policies following the midterm elections also helped drive stock prices higher.

S&P 600 Index Posted Gains in All Market Sectors

All of the market sectors represented in the S&P 600 Index posted positive absolute returns for the reporting period, testament to the breadth of the market rally. Consumer discretionary stocks produced especially attractive relative returns in the recovering economy, as low-end retailers, farming equipment suppliers, office supply stores and casual dining restaurants led the market rally.

In the information technology sector, several semiconductor companies benefited from the proliferation of devices used in wireless communications. In addition, a number of software developers and hardware providers fared well as more businesses moved toward “cloud computing,” in which companies maintain and gain access to data and applications over the Internet. Electronic equipment makers benefited

4

from an expansion in corporations’ technology budgets as companies made purchases that were postponed during the downturn. Among industrial companies, machinery manufacturers serving the aerospace industry performed especially well. Finally, some of the S&P 600 Index’s top performers in 2010 included real estate investment trusts, which benefited from easier access to the capital markets as confidence returned to the commercial real estate market.

Although disappointments in 2010 proved to be relatively mild, capital markets participants in the financials sector suffered from lower trading volumes, reduced mergers-and-acquisitions activity and a number of company-specific problems.

Index Investing Offers Diversification Benefits

As an index fund, our strategy is to attempt to replicate the returns of the S&P 600 Index by investing in a representative sample of the stocks listed in the S&P 600 Index. The fund’s investments are not affected by any individual preference for one market or security over another. Instead, the fund employs a passive management approach in which all investment decisions are based on the composition of the S&P 600 Index.

January 18, 2011

Equity funds are subject generally to market, market sector, market liquidity, issuer, and investment
style risks, among other factors, to varying degrees, all of which are more fully described in the
fund’s prospectus. Stocks of small- and/or midcap companies often experience sharper price
fluctuations than stocks of large-cap companies.
The fund is only available as a funding vehicle under variable life insurance policies or variable
annuity contracts issued by insurance companies. Individuals may not purchase shares of the fund
directly.A variable annuity is an insurance contract issued by an insurance company that enables
investors to accumulate assets on a tax-deferred basis for retirement or other long-term goals.

1 Total return includes reinvestment of dividends and any capital gains paid. Past performance is no
guarantee of future results. Share price and investment return fluctuate such that upon redemption,
fund shares may be worth more or less than their original cost.The fund’s performance does not
reflect the deduction of additional charges and expenses imposed in connection with investing in
variable insurance contracts, which will reduce returns.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Investment Portfolios (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open end management investment company, operating as a series company currently offering four series, including the Small Cap Stock Index Portfolio (the “fund”).The fund is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies.The fund is a diversified series.The fund’s investment objective is to match the performance of the Standard & Poor’s SmallCap 600 Index.The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold without a sales charge.

The Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions.Actual results could differ from those estimates.

The Fund 33

NOTES TO FINANCIAL STATEMENTS (continued)

The Company enters into contracts that contain a variety of indemnifications.The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices. Bid price is used when no asked price is available. U.S.Treasury Bills are valued at the mean between quoted bid prices and asked prices by an independent pricing service approved by the Board of Trustees. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board ofTrustees. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Trustees, certain factors may be considered such as: fundamental analytical data, the nature and duration of restrict ions on disposition, an evaluation of the forces that influence the mar-

34

ket in which the securities are purchased and sold and public trading in similar securities of the issuer or comparable issuers. Financial futures are valued at the last sales price.

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Fund 35

The following is a summary of the inputs used as of December 31, 2010 in valuing the fund’s investments:

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about FairValue Measurements”. The portions of ASU No. 2010-06 which require reporting entities to prepare new disclosures surrounding amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3 have been adopted by the fund. No significant transfers between Level 1 or Level 2 fair value measurements occurred at December 31, 2010. The remaining portion of ASU No. 2010-06 requires reporting entities to make new disclosures about information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. These new and re vised disclosures are required to be implemented for fiscal years beginning after December 15, 2010. Management is currently evaluat-

36

ing the impact that the adoption of this remaining portion of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager, U.S. Government and Agency securities or letters of credit.The fund is entitled to receive all income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of r ights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended December 31, 2010, The Bank of New York Mellon earned $35,796 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” in the Act.

The Fund 37

NOTES TO FINANCIAL STATEMENTS (continued)

The fund may invest in shares of certain affiliated investment companies also advised or managed by Dreyfus. Investments in affiliated investment companies for the period ended December 31, 2010 were as follows:

 

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) 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 interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended December 31, 2010, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

38

Each of the tax years in the four-year period ended December 31, 2010 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At December 31, 2010, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $1,067,626, undistributed capital gains $426,817 and unrealized appreciation $24,674,103.

The tax character of distributions paid to shareholders during the fiscal periods ended December 31, 2010 and December 31, 2009 were as follows: ordinary income $784,411 and $2,555,228 and long-term capital gains $0 and $17,296,536, respectively.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in a $225 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing.

The average amount of borrowings outstanding under the Facilities during the period ended December 31, 2010 was approximately $21,100, with a related weighted average annualized interest rate of 1.47%.

NOTE 3—Investment Advisory Fee and Other Transactions With Affiliates:

(a) Pursuant to an investment advisory agreement with the Manager, the investment advisory fee is computed at the annual rate of .35% of the value of the fund’s average daily net assets and is payable monthly. Under the terms of the Agreement, the Manager has agreed to pay all of the

The Fund 39

NOTES TO FINANCIAL STATEMENTS (continued)

expenses of the fund except investment advisory fees, Rule 12b-1 distribution plan fees, taxes, interest expenses, brokerage commissions, fees and expenses of independent counsel to the fund and the non-interested Board members, and extraordinary expenses. In addition, the Manager has also agreed to reduce its fee in an amount equal to the fund’s allocated portion of the accrued fees and expenses of non-interested Board members and fees and expenses of independent counsel to the fund.

(b) Under the Distribution Plan (the “Plan”) adopted pursuant to Rule 12b-1 under the Act, the fund pays the Distributor for distributing its shares, for servicing and/or maintaining shareholder accounts and for advertising and marketing.The Plan provides for payments to be made at an annual rate of .25% of the value of the fund’s average daily net assets. The Distributor may make payments to Participating Insurance Companies and to brokers and dealers acting as principal underwriter for their variable insurance products. The fees payable under the Plan are payable without regard to actual expenses incurred. During the period ended December 31, 2010, the fund was charged $361,177 pursuant to the Plan.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: investment advisory fees $51,624 and Rule 12b-1 distribution plan fees $36,874.

(c) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and financial futures, during the period ended December 31, 2010, amounted to $62,360,881 and $46,524,202, respectively.

40

The provisions of ASC Topic 815 “Derivatives and Hedging” require qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments and disclosures about credit-risk-related contingent features in derivative agreements. The disclosure requirements distinguish between derivatives, which are accounted for as “hedges” and those that do not qualify for hedge accounting. Because investment companies value their derivatives at fair value and recognize changes in fair value through the Statement of Operations, they do not qualify for such accounting. Accordingly, even though a fund’s investments in derivatives may represent economic hedges, they are considered to be non-hedge transactions for purposes of this disclosure.

Futures Contracts: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk, as a result of changes in value of underlying financial instruments. The fund invests in financial futures contracts in order to manage its exposure to or protect against changes in the market.A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a broker, which consist of cash or cash equivalents. The amount of these deposits is determined by the exchange or Board of Trade on which the contract is traded and is subject to change. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which ar e recorded in the Statement of Operations. Futures contracts are valued daily at the last sales price established by the Board of Trade or exchange upon which they are traded.When the contracts are closed, the fund recognizes a realized gain or loss. There is minimal counterparty credit risk to the fund with futures since futures are exchange traded, and

INFORMATION ABOUT THE REVIEW AND
APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT (Unaudited)

At a meeting of the Board of Trustees of the Company held on July 14 and 15, 2010, the Board considered the re-approval for an annual period (through August 31, 2011) of the fund’s Investment Advisory Agreement (the “Management Agreement”) with the Manager, pursuant to which the Manager provides the fund with investment advisory and administrative services.The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Company, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent and Quality of Services Provided to the Fund.The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement.The Manager’s representatives reviewed the fund’s distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each.The Board noted that the fund’s shares are offered only to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies. The Manager’s representatives noted the diversity of distribution among the funds in the Dreyfus fund complex, an d the Manager’s corresponding need for broad, deep and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including that of the fund.The Manager also provided the number of separate accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered the Manager’s research and portfolio management capabilities and that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements.The Board members also considered the Manager’s extensive administrative,

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

accounting and compliance infrastructure.The Board also considered the Manager’s brokerage policies and practices, the standards applied in seeking best execution and the Manager’s policies and practices regarding soft dollars.

Comparative Analysis of the Fund’s Performance and Investment Advisory Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to three other pure index funds underlying variable insurance products that are benchmarked against the S&P SmallCap 600 Index (the “Performance Group”) and to a larger universe of funds, consisting of all small-cap core funds underlying variable insurance products (the “Performance Universe”), selected and provided by Lipper, Inc., an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below).The Board members discussed the results of the comparisons for var ious periods ended May 31, 2010. The Board members noted that the fund’s total return performance was the highest or second highest of the funds in the Performance Group for each period. The Board members also noted that the fund’s total return performance was above the Performance Universe medians for all periods.The Manager also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s investment advisory fee and expense ratio and reviewed the range of investment advisory fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper.The Board members noted that the fund’s actual and contractual investment advisory fees were the second lowest of the funds in the Expense Group and lower than the Expense Group medians, although the total expense ratio was the highest of the four.They also noted that the fund’s actual investment

46

advisory fee was lower than the Expense Universe median, but that its total expense ratio was higher than the Expense Universe median.

Representatives of the Manager reviewed with the Board members the investment advisory fees paid by the only other mutual fund managed by the Manager or its affiliates underlying variable insurance products with similar investment objectives, policies and strategies, and included within the fund’s Lipper category (the “Similar Fund”), and by other accounts managed by the Manager or its affiliates with similar investment objectives, policies and strategies as the fund (the “Similar Accounts”).The Manager’s representatives explained the nature of the Similar Accounts and the differences in providing services to such Similar Accounts as compared to managing and providing services to the fund. The Board analyzed the differences in fees paid to the Manager and discussed the relationship of the fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Fund and Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s investment advisory fee.

Analysis of Profitability and Economies of Scale.The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board previously had been provided with information prepared by an independent consulting firm regarding the Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund com-plex.The Board members also had been informed that the methodology had been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable.The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund. The Board members evaluated the prof itability analysis in light of the rele-

The Fund 47

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

vant circumstances for the fund, and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors.The Board members also considered potential benefits to the Manager from acting as investment adviser to the fund, including any soft dollar arrangements with respect to trading the fund’s investments.

It was noted that the Board members should consider the Manager’s profitability with respect to the fund as part of their evaluation of whether the fee under the Management Agreement bears a reasonable relationship to the mix of services provided by the Manager, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund’s assets had been decreasing, the possibility that the Manager may have realized any economies of scale would be less. It also was noted that the Manager did not realize a profit on the fund’s operations.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

• The Board concluded that the nature, extent and quality of the services provided by the Manager are adequate and appropriate.

• The Board was generally satisfied with the fund’s relative performance.

• The Board concluded that the fee paid by the fund to the Manager was reasonable in light of the services provided, comparative perfor- mance, expense and investment advisory fee information, costs of the services provided and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.

48

• The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of the fund had been adequately considered by the Manager in con- nection with the investment advisory fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the Management Agreement was in the best interests of the fund and its shareholders.

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Investment Portfolios, Technology Growth Portfolio, covering the 12-month period from January 1, 2010, through December 31, 2010.

Although 2010 proved to be a volatile year for stocks, the reporting period ended with a sustained market rally that produced above-average returns across most market-cap segments for the calendar year. Investors’ early concerns regarding sovereign debt issues in Europe and stubbornly high unemployment in the United States later gave way to optimism that massive economic stimulus programs, robust growth in the world’s emerging markets, a strong holiday retail season and rising corporate earnings signaled better economic times ahead.

We are aware that stocks have recently reached higher valuations, and that any new economic setbacks could result in market volatility as investors adjust their expectations. Nonetheless, we see value in many segments of the equity market. For example, investors in volatile markets may turn to high-quality stocks of U.S. companies with track records of consistent growth in a variety of economic climates, and international equities could benefit from a declining U.S. dollar and potentially higher growth opportunities abroad.With 2011 now upon us, we suggest talking to your financial advisor, who can help you identify potential opportunities and suggest strategies suitable for your individual needs in today’s market environment.

For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2010, through December 31, 2010, as provided by Barry K. Mills, CFA, Portfolio Manager

Fund and Market Performance Overview

For the 12-month period ended December 31, 2010, Dreyfus Investment Portfolios,Technology Growth Portfolio’s Initial shares produced a total return of 29.93%, and its Service shares produced a total return of 29.65%.¹ The fund’s benchmarks, the Morgan Stanley High Technology 35 Index (“MS High Tech 35 Index”) and the Standard & Poor’s 500 Composite Stock Price Index (“S&P 500 Index”), produced total returns of 16.03% and 15.08%, respectively, over the same period.^2,3

A stock market rally late in the year more than offset earlier weakness as economic uncertainty waned and investor sentiment improved.The fund produced higher returns than its benchmarks, primarily due to our emphasis on companies benefiting from the widespread adoption of new technologies.

The Fund’s Investment Approach

The fund seeks capital appreciation by normally investing at least 80% of its assets in the stocks of growth companies of any size that Dreyfus believes to be leading producers or beneficiaries of technological innovation. In choosing stocks, the fund looks for technology companies with the potential for strong earnings or revenue growth rates, although some of the fund’s investments may currently be experiencing losses.The fund’s investment process centers on a multi-dimensional approach that looks for opportunities across emerging growth, cyclical or stable growth companies.The fund’s investment approach seeks companies that appear to have strong earnings momentum, positive earnings revisions, favorable growth, product or market cycles and/or favorable valuations.

Waning Economic Concerns Fueled a Market Rally

Soon after the start of 2010, a number of new developments shook investors’ confidence in ongoing global and domestic economic recoveries. Europe was roiled by a sovereign debt crisis that led to austerity measures throughout the region, and mixed housing and employment

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

data in the United States weighed on already mild growth.A catastrophic oil spill in the Gulf of Mexico also added to economic uncertainty.As a result, stocks generally declined amid heightened volatility over the first half of the year.

As the year progressed, however, it became clearer that investors’ economic concerns may have been overblown. Corporate earnings improved, commodity prices climbed amid robust demand from the emerging markets, and the U.S. and global economies remained on mildly upward trajectories. New stimulative efforts by the Federal Reserve Board also boosted investor sentiment, and the resulting market rally helped the S&P 500 Index end the year with double-digit gains.

The information technology sector participated fully in the broader market’s gains. However, small- and midcap stocks typically fared better than larger technology stocks, and growth-oriented stocks outperformed their value-oriented counterparts.

Security Selections Bolstered Relative Performance

The fund’s returns in 2010 outpaced the MS High Tech 35 Index, due primarily to our focus on companies poised to benefit from new technological trends. Companies engaged in “cloud computing,” server virtualization, smartphones and software development generally produced higher returns than companies selling more mature technologies. In addition, smaller companies considered potential targets for acquisition by larger rivals fared well in 2010.

As more business enterprises shifted their technology infrastructures to cloud computing, in which applications and data are accessed over the Internet, companies involved in the emerging technology increasingly attracted investors’ attention. Fund holdings Akamai Technologies, VMWare, Riverbed Technology and Informatica benefited from this trend. Similarly, online movie rental company Netflix achieved higher sales and earnings during a shift from U.S. mail delivery of DVDs to Internet delivery of streaming video. Holdings that gained value after receiving acquisition offers included enterprise software developer Sybase and security software specialist McAfee.The fund also benefited from not owning some of the information technology sector’s laggards in 2010, including companies—such as SeagateTechnology, Nokia and Dell—that may have been slow in migrating away from more mature technology paradigms.

4

Although disappointments in 2010 proved relatively mild, the fund’s laggards included wireless communications pioneer QUALCOMM, which suffered from inventory-related issues; smartphone maker Research in Motion, which lost market share to competitors; Google, which encountered intensifying competitive pressures; and Microsoft, which has been slow to adapt to cloud computing. In addition, the fund did not own some of the MS High Tech 35 Index’s better performers, including Intuit and Infosys.

Finding Value in a Growing Market

The market rally over the second half of 2010 left many stocks, including those in the information technology sector, with richer valuations. However, we have continued to seek attractive opportunities in the market sector, especially among companies that may have been punished more severely than warranted by their underlying business fundamentals. Therefore, we recently augmented the fund’s holdings of companies engaged in secular growth themes with value-oriented investments in a select group of semiconductor and disk-drive manufacturers.

Please note, the position in any security highlighted in italicized typeface was sold during the
reporting period.
The fund’s share price is likely to be more volatile than that of other funds that do not
concentrate in one sector.The technology sector involves special risks, such as the faster rate of
change and obsolescence of technological advances, and has been among the most volatile sectors of
the stock market.
Equity funds are subject generally to market, market sector, market liquidity, issuer and investment
style risks, among other factors, to varying degrees, all of which are more fully described in the
fund’s prospectus.
The fund is only available as a funding vehicle under variable life insurance policies or variable
annuity contracts issued by insurance companies. Individuals may not purchase shares of the fund
directly.A variable annuity is an insurance contract issued by an insurance company that enables
investors to accumulate assets on a tax-deferred basis for retirement or other long-term goals.
1 Total return includes reinvestment of dividends and any capital gains paid. Past performance is no
guarantee of future results. Share price and investment return fluctuate such that upon redemption,
fund shares may be worth more or less than their original cost.The fund’s performance does not
reflect the deduction of additional charges and expenses imposed in connection with investing in
variable insurance contracts, which will reduce returns.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Investment Portfolios (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company, operating as a series company, currently offering four series, including the Technology Growth Portfolio (the “fund”). The fund is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies.The fund is a diversified series.The fund’s investment objective is to seek capital appreciation. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser.

MBSC Service Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares, which are sold without a sales charge.The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Initial and Service. Each class of shares has identical rights and privileges, except with respect to the distribution plan and the expenses borne by each class, the allocation of certain transfer agency costs and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for

The Fund 17

NOTES TO FINANCIAL STATEMENTS (continued)

SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions.Actual results could differ from those estimates.

The Company enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. Securities not listed on an exchange or the national securities market, or securities for which there were no transactions, are valued at the average of the most recent bid and asked prices, except for open short positions, where the asked price is used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value.When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Trustees. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures contracts. For other securities that are fair valued by the Board of Trustees, certain factors may be

18

considered such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers.

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Fund 19

NOTES TO FINANCIAL STATEMENTS (continued)

The following is a summary of the inputs used as of December 31, 2010 in valuing the fund’s investments:

		Level 2—Other	Level 3—
	Level 1—	Significant	Significant
	Unadjusted	Observable	Unobservable
	Quoted Prices	Inputs	Inputs	Total

† See Statement of Investments for additional detailed categorizations.

In January 2010, FASB issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about FairValue Measurements”. The portions of ASU No. 2010-06 which require reporting entities to prepare new disclosures surrounding amounts and reasons for significant transfers in and out of Level 1 and Level 2 fair value measurements as well as inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3 have been adopted by the fund. No significant transfers between Level 1 or Level 2 fair value measurements occurred at December 31, 2010.The remaining portion of ASU No. 2010-06 requires reporting entities to make new disclosures about information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of activity in Level 3 fair value measurements. These new and rev ised disclosures are required to be implemented for fiscal years beginning after December 15, 2010. Management is currently evaluating the impact that the adoption of this remaining portion of ASU No. 2010-06 may have on the fund’s financial statement disclosures.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income, including, where applicable, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

20

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by the Manager, U.S. Government and Agency securities or letters of credit.The fund is entitled to receive all income on securities loaned, in addition to income earned as a result of the lending transaction. Although each security loaned is fully collateralized, the fund bears the risk of delay in recovery of, or loss of r ights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended December 31, 2010, The Bank of New York Mellon earned $4,445 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” in the Act.

The fund may invest in shares of certain affiliated investment companies also advised or managed by Dreyfus. Investments in affiliated investment companies for the period ended December 31, 2010 were as follows:

The Fund 21

NOTES TO FINANCIAL STATEMENTS (continued)

(d) Dividends to shareholders: Dividends are recorded on the ex-dividend date. Dividends from investment income-net and dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) 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 interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended December 31, 2010, the fund did not have any liabilities for any uncertain tax positions.The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period, the fund did not incur any interest or penalties.

Each of the tax years in the four-year period ended December 31, 2010 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At December 31, 2010, the components of accumulated earnings on a tax basis were as follows: accumulated capital losses $38,343,113 and unrealized appreciation $43,506,325.

The accumulated capital loss carryover is available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to December 31, 2010. If not applied, $7,722,694 of the carryover expires in fiscal 2011, $3,537,823 expires in fiscal 2012, $11,980,354 expires in fiscal 2016 and $15,102,242 expires in fiscal 2017.

22

The tax character of distributions paid to shareholders during the fiscal periods ended December 31, 2010 and December 31, 2009 were as follows: ordinary income $0 and $364,149, respectively.

During the period ended December 31, 2010, as a result of permanent book to tax differences, primarily due to the tax treatment for net operating losses and capital loss carryover expiration, the fund increased accumulated undistributed investment income-net by $910,683, increased accumulated net realized gain (loss) on investments by $5,432,576 and decreased paid-in-capital by $6,343,259. Net assets and net asset value per share were not affected by this reclassification.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in a $225 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon, (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of the respective Facility at the time of borrowing. During the period ended December 31, 2010, the fund did not borrow under the Facilities.

NOTE 3—Investment Advisory Fee and Other Transactions With Affiliates:

(a) Pursuant to an investment advisory agreement with the Manager, the investment advisory fee is computed at the annual rate of .75% of the value of the fund’s average daily net assets and is payable monthly.

(b) Under the Distribution Plan (the “Plan”) adopted pursuant to Rule 12b-1 under the Act, Service shares pay the Distributor for distributing its shares, for servicing and/or maintaining Service shares’

The Fund 23

NOTES TO FINANCIAL STATEMENTS (continued)

shareholder accounts and for advertising and marketing for Service shares.The Plan provides for payments to be made at an annual rate of .25% of the value of the Service shares’ average daily net assets. The Distributor may make payments to Participating Insurance Companies and to brokers and dealers acting as principal underwriter for their variable insurance products. The fees payable under the Plan are payable without regard to actual expenses incurred. During the period ended December 31, 2010, Service shares were charged $288,883 pursuant to the Plan.

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the Manager, under a transfer agency agreement for providing personnel and facilities to perform transfer agency services for the fund. During the period ended December 31, 2010, the fund was charged $452 pursuant to the transfer agency agreement, which is included in Shareholder servicing costs in the Statement of Operations.

The fund has arrangements with the custodian and cash management bank whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset custody and cash management fees. For financial reporting purposes, the fund includes net earnings credits as an expense offset in the Statement of Operations.

The fund compensates The Bank of New York Mellon under a cash management agreement for performing cash management services related to fund subscriptions and redemptions. During the period ended December 31, 2010, the fund was charged $79 pursuant to the cash management agreement, which is included in Shareholder servicing costs in the Statement of Operations.These fees were partially offset by earnings credits of $5.

The fund also compensates The Bank of New York Mellon under a custody agreement for providing custodial services for the fund. During the period ended December 31, 2010, the fund was charged $14,738 pursuant to the custody agreement.

24

During the period ended December 31, 2010, the fund was charged $6,243 for services performed by the Chief Compliance Officer.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: investment advisory fees $149,780, Rule 12b-1 distribution plan fees $30,522, custodian fees $4,200, chief compliance officer fees $1,728 and transfer agency per account fees $76.

(c) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities, during the period ended December 31, 2010, amounted to $190,502,936 and $196,508,310, respectively.

INFORMATION ABOUT THE REVIEW
AND APPROVAL OF THE FUND’S
INVESTMENT ADVISORY AGREEMENT (Unaudited)

At a meeting of the Board of Trustees of the Company held on July 14 and 15, 2010, the Board considered the re-approval for an annual period (through July 29, 2011) of the fund’s Investment Advisory Agreement (the “Management Agreement”) with the Manager, pursuant to which the Manager provides the fund with investment advisory and administrative services.The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Company, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent and Quality of Services Provided to the Fund. The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent and quality of the services provided to the fund pursuant to its Management Agreement.The Manager’s representatives reviewed the fund’s distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each.The Board noted that the fund’s shares are offered only to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies.The Manager’s representatives noted the diversity of distribution among the funds in the Dreyfus fund complex, an d the Manager’s corresponding need for broad, deep and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including that of the fund. The Manager also provided the number of separate accounts investing in the fund, as well as the fund’s asset size.

The Board members also considered the Manager’s research and portfolio management capabilities and that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements. The Board members also considered the Manager’s extensive administrative, accounting and compliance infrastructure.

Comparative Analysis of the Fund’s Performance and Investment Advisory Fee and Expense Ratio. The Board members reviewed the fund’s performance and comparisons to a group of science and technology funds underlying variable insurance products (the “Performance Group”) and to a larger universe of funds, consisting of all science and technology funds underlying variable insurance products (the “Performance Universe”), selected and provided by Lipper, Inc., an independent provider of investment company data.The Board was provided with a description of the methodology Lipper used to select the Performance Group and Performance Universe, as well as the Expense Group and Expense Universe (discussed below).The Board members discussed the results of the comparisons for various periods ended May 31, 2010.The Board members noted that the fund’s total return performance was above the Performance Universe medians for all periods. In addition, the Board members noted that the fund’s total return performance was at or above the Performance Group medians for the 1-, 2-, and 3- year periods, and was below the Performance Group medians for all other periods.The Manager also provided a comparison of the fund’s calendar year total returns to the returns of the fund’s benchmark index.

The Board members also discussed the fund’s investment advisory fee and expense ratio and reviewed the range of investment advisory fees and expense ratios as compared to a comparable group of funds (the “Expense Group”) and a broader group of funds (the “Expense Universe”), each selected and provided by Lipper.The Board members noted that the actual investment advisory fee and total expense ratio of the fund’s Initial shares (which are not subject to a Rule 12b-1 plan) were lower than the Expense Group and Expense Universe medians and that the fund’s contractual investment advisory fee was also lower than the Expense Group median. In addition, the Board noted that the expense ratio of the fund’s Service shares (which are subject to a Rule 12b-1 plan) was lower than the Expense Universe medians, but higher than the Expense Group medians.

Representatives of the Manager noted that the Manager or its affiliates do not manage other mutual funds with similar investment objectives, policies and strategies as the fund underlying variable insurance products and included within the fund’s Lipper category. Nor does the Manager or its affiliates manage other accounts with similar investment objectives, policies and strategies as the fund.

Analysis of Profitability and Economies of Scale. The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board previously had been provided with information prepared by an independent consulting firm regarding the Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund complex. The Board members also had been informed that the methodology had been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable.The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund. The Board members evaluated the pro fitability analysis in light of the relevant circumstances for the fund, and the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors.The Board members also considered potential benefits to the Manager from acting as investment adviser to the fund, including any soft dollar arrangements with respect to trading the fund’s investments.

It was noted that the Board members should consider the Manager’s profitability with respect to the fund as part of their evaluation of whether the fee under the Management Agreement bears a reasonable relationship to the mix of services provided by the Manager, including the nature, extent and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund’s assets had been decreasing, the possibility that the Manager may have

INVESTMENT ADVISORY AGREEMENT (Unaudited) (continued)

realized any economies of scale would be less. It also was noted that the Manager did not realize a profit on the fund’s operations.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

• The Board concluded that the nature, extent and quality of the services provided by the Manager are adequate and appropriate.

• The Board was satisfied with the fund’s relative performance.

• The Board concluded that the fee paid by the fund to the Manager was reasonable in light of the services provided, comparative perfor- mance, expense and investment advisory fee information, costs of the services provided and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.

• The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of the fund had been adequately considered by the Manager in con- nection with the investment advisory fee rate charged to the fund and that, to the extent in the future it were determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the Management Agreement was in the best interests of the fund and its shareholders.
