A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Global Real Estate Securities Fund, covering the six-month period from January 1, 2011, through June 30, 2011. 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.

Although 2011 began on an optimistic note amid encouraging economic data, by midyear investors returned to a more cautious outlook. The U.S. and global economies continued to grow over the reporting period, but at a relatively sluggish pace. First, manufacturing activity proved unsustainably strong in late 2010 and early 2011, leading to a subsequent slowdown in new orders. Second, turmoil in the Middle East drove oil prices higher and produced an inflationary drag on real incomes.Third, natural and nuclear disasters in Japan added to upward pressure on energy prices, and these unexpected events disrupted the global supply chain, especially in the automotive sector. Finally, in the United States, disappointing labor and housing markets weighed on investor sentiment. As a result, U.S. stocks generally produced only modest gains over the first half of the year.

We expect economic conditions to improve over the second half of 2011. Inflationary pressures appear to be peaking in most countries, including the United States, and we have already seen energy prices retreat from their highs. In addition, a successful resolution to the current debate regarding government spending and borrowing, without major fiscal tightening over the near term, should help avoid a serious disruption to the domestic economy. To assess how these and other developments may affect your investments, we encourage you, as always, to speak with your financial advisor.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2011, through June 30, 2011, as provided by Peter Zabierek and Dean Frankel, Portfolio Managers, Urdang Securities Management, Inc., Sub-Investment Adviser

Fund and Market Performance Overview

For the six-month period ended June 30, 2011, Dreyfus Global Real Estate Securities Fund’s Class A shares produced a total return of 5.83%, Class C shares returned 5.31% and Class I shares returned 5.95%.¹In comparison, the FTSE EPRA/NAREIT Developed Index, the fund’s benchmark, achieved a total return of 6.08% for the same period.²

A debt crisis in Europe, natural and nuclear disasters in Japan, turmoil in North Africa, and disappointing global economic data weighed on investor sentiment during the second quarter of 2011, partially offsetting stronger returns stemming from the global economic recovery during the first quarter. The fund’s returns were roughly in line with its benchmark, as successes in the United States, United Kingdom and Singapore were balanced by lagging returns in Hong Kong and Japan.

The Fund’s Investment Approach

The fund seeks to maximize total return consisting of capital appreciation and current income by investing at least 95% of its assets in companies principally engaged in the real estate sector. The fund normally invests approximately 60% of its assets in companies located outside the United States, and invests in at least 10 different countries. The fund also may invest in companies located in emerging markets and in companies of any market capitalization. Our proprietary approach quantifies investment opportunity both from a real estate and stock perspective.

Shifting Sentiment Sparked Market Volatility

Global economic sentiment had improved dramatically by the start of 2011, fueled by quantitative easing of U.S. monetary policy, better-than-expected economic data in Europe and strong corporate earnings across a number of regions. As a result, real estate stock prices moved higher during the first quarter of the year. However, a number of


The Fund	3

DISCUSSION OF FUND PERFORMANCE (continued)

macroeconomic developments soon weighed on investor sentiment. Inflation worries prompted a number of central banks, including those in China and Europe, to raise short-term interest rates and tighten credit standards. Political uprisings in the Middle East and devastating natural and nuclear disasters in Japan added to investors’ concerns. Later, worries intensified regarding the European sovereign debt crisis as Greece teetered on the brink of default. These macroeconomic developments caused real-estate stocks to give back some, but not all, of their earlier gains in the second quarter.

Security Selections Produced Mixed Results

In this choppy market environment, we allocated about 40% of the fund’s assets to U.S. real estate stocks and approximately 60% to opportunities overseas. Our security selection strategy in the United States proved particularly successful over the first half of 2011. The fund scored a number of winners among real estate investment trusts (REITs) focusing on rental apartments, which fared well as demand for rentals increased and home ownership declined. Conversely, we maintained relatively light exposure to U.S. health care-related properties, a position that benefited relative performance when the sub-sector cooled. In addition, the fund’s position in National Health Properties gained value when the company was acquired at a premium to its stock price byVenta REIT.

Investments in the United Kingdom also produced above-average results. Particularly beneficial was an overweighted position in Unite Group, a specialist in student accommodations, which gained value as earlier strategic missteps were addressed.The fund also benefited from overweighted exposure to Land Securities Group, a UK REIT that owns both office and retail properties. In Singapore, overweighted exposure to REITs and an underweighted position in developers bolstered results when the government’s efforts to fight inflation discouraged residential development. Finally, Charter Hall Office REIT, which owns office properties in Australia and the United States, outperformed due to management’s published strategy to sell the company’s US assets and Canadian multifamily specialist Boardwalk Real Estate Investment Trust advanced after reporting robust financial results.

Disappointments during the reporting period were concentrated in the Hong Kong market, where inflation-fighting measures prompted us to

shift the fund’s emphasis from residential properties to the office market. We had established overweighted exposure to Japanese condominiums before the earthquake and tsunami damaged a number of coastal property developments, which dampened investor sentiment and led to the cancellation of some high-rise residential projects. Canada’s Chartwell Senior Housing Real Estate Investment Trust declined despite strong business fundamentals as investors favored the value opportunities.

Selectivity More Important in an Uncertain World

As of midyear, the emerging markets appear to be nearing the end of their inflation-fighting efforts, and we have identified a number of attractive values in Asia and Latin America. However, parts of Europe have remained under pressure from the sovereign debt crisis, leading us to maintain an underweighted position in most European countries outside of the United Kingdom and Scandinavia.We also have reduced the fund’s exposure to Japan and Hong Kong. In our judgment, these are prudent strategies until we see more consistent signs of a robust global recovery.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Global Real Estate Securities Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering ten series, including the fund. The fund’s investment objective is to maximize total return consisting of capital appreciation and current income. 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. Urdang Securities Management, Inc. (“Urdang”) serves as the fund’s sub-investment advisor. Urdang is a wholly-owned subsidiary of BNY Mellon and an affiliate of Dreyfus.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of Dreyfus, is the distributor of the fund’s shares.The fund is authorized to issue 250 million shares of $.001 par value Common Stock.The fund currently offers three classes of shares: Class A (100 million shares authorized), Class C (50 million shares authorized) and Class I (100 million shares authorized). Class A shares are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to 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 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.

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 Directors. 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 Directors, 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. Investments denominated in foreign currencies are translated to U.S. dollars at the prevailing rates of exchange. Forward foreign currency exchange contracts (“forward contracts”) are valued at the forward rate.

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 following is a summary of the inputs used as of June 30, 2011 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


The Fund	21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 June 30, 2011.

In May 2011, FASB issued ASU No. 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in GAAP and International Financial Reporting Standards (“IFRS”)”. ASU No. 2011-04 includes common requirements for measurement of and disclosure about fair value between GAAP and IFRS. ASU No. 2011-04 will require reporting entities to disclose the following information for fair value measurements categorized within Level 3 of the fair value hierarchy: quantitative information about the unobservable inputs used in the fair value measurement, the valuation processes used by the reporting entity and a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs. In addition,ASU No. 2011-04 will require reporting entities to make disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. The new and revised disclosures are effective for interim and annual reporting periods beginning after December 15, 2011. At this time, management is evaluating the implications of ASU No. 2011-04 and its impact on the financial statements.

(b) Foreign currency transactions: The fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized on securities transactions between trade and settlement date, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities other than

investments resulting from changes in exchange rates. Foreign currency gains and losses on investments are included with net realized and unrealized gain or loss on investments.

(c) 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.

Investing in foreign markets may involve special risks and considerations not typically associated with investing in the U.S. These risks include revaluation of currencies, high rates of inflation, repatriation restrictions on income and capital, and adverse political and economic developments. Moreover, securities issued in these markets may be less liquid, subject to government ownership controls and delayed settlements, and their prices may be more volatile than those of comparable securities in the U.S.

(d) 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 June 30, 2011 were as follows:


Affiliated
Investment	Value			Value	Net
Company	12/31/2010 ($)	Purchases ($)	Sales ($)	6/30/2011 ($)	Assets (%)

Plus Money
Market Fund	4,159,000	52,082,000	52,953,000	3,288,000	1.5

(e) 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

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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.

(f) 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 June 30, 2011, 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 three-year period ended December 31, 2010 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The fund has an unused capital loss carryover of $24,379,441 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, $6,895,360 of the carryover expires in fiscal 2016 and $17,484,081 expires in fiscal 2017.

The tax character of distributions paid to shareholders during the fiscal year ended December 31, 2010 was as follows: ordinary income $5,684,262. The tax character of current year distributions will be determined at the end of the current fiscal year.

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, a subsidiary of BNY Mellon and an affiliate of Dreyfus, (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 on June 30, 2011, the fund did not borrow under the Facilities.

Dreyfus had contractually agreed, until May 1, 2011, to waive receipt of its fees and/or assume the expenses of the fund so that the direct expenses of Class I shares (excluding taxes, interest, brokerage commissions, commitment fees on borrowings and extraordinary expenses) did not exceed 1.20% of the value of Class I shares’ average daily net assets.

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large Cap Equity Fund, covering the six-month period from January 1, 2011, through June 30, 2011. 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, 2011, through June 30, 2011, as provided by Irene D. O’Neill, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended June 30, 2011, Dreyfus Large Cap Equity Fund’s Class A shares produced a total return of 5.57%, Class C shares returned 5.26% and Class I shares returned 5.88%.¹In comparison, the Standard and Poor’s 500 Composite Stock Price Index (“S&P 500 Index”), the fund’s benchmark, achieved a total return of 6.01%.²

Although stocks rallied early in the year as an economic recovery appeared to gain traction, renewed concerns later caused the market to give back some of its previous gains.The fund produced lower returns than its benchmark, primarily due to shortfalls in the consumer discretionary and utilities sectors.

The Fund’s Investment Approach

The fund seeks long-term capital appreciation.To pursue this goal, the fund normally invests at least 80% of its assets in equity securities of large-capitalization companies with market capitalizations of $5 billion or more at the time of purchase.

The fund invests primarily in large, established companies that we believe have proven track records and the potential for superior relative earnings growth.The investment process begins with a “top-down” assessment of broad economic, political and social trends and their implications for different market and industry sectors. Fundamental research is used to identify companies with the potential for above-average earnings and revenue growth; sustainable competitive advantage; strong or improving financial condition; and/or earnings power that is either unrecognized or underestimated by the market.

Shifting Sentiment Sparked Heightened Volatility

Investors’ outlooks had improved dramatically by the start of 2011 due to improvements in employment, consumer spending and corporate earnings, sending stock prices broadly higher. However, the rally was interrupted in February when political unrest in North Africa/Middle


The Fund	3

DISCUSSION OF FUND PERFORMANCE (continued)

East led to sharply rising energy prices, and again in March when devastating natural and nuclear disasters in Japan threatened one of the world’s largest economies. Nonetheless, investors proved resilient, and stocks bounced back from these unexpected shocks.

In late April, investor sentiment began to deteriorate in earnest when Greece appeared headed for default on its sovereign debt, U.S. economic data proved disappointing and a contentious debate regarding U.S. government spending and borrowing intensified. Stocks suffered bouts of heightened volatility as newly risk-averse investors shifted their focus from economically sensitive industry groups to those that historically have held up well under uncertain economic conditions.

Security Selections Produced Mixed Results

Although the fund participated to a substantial degree in the market’s gains over the first half of 2011, results compared to the benchmark were undermined by a handful of disappointments in the consumer discretionary sector, where cruise line Carnival suffered when oil prices climbed and itineraries needed to be rerouted due to political instability in Northern Africa. In addition, mass merchandiser Target was hurt by weaker consumer spending among its customer base.The fund did not participate fully in above-average returns from the utilities sector, where most companies did not meet our earnings growth criteria. Moreover, electric utility company Sempra Energy lagged when investors reacted negatively to a management change.

The fund achieved better results in other areas. Overweighted exposure to the better-performing information technology sector produced particularly strong relative performance. Successful stock selections among technology companies included consulting services providers Accenture and International Business Machines, which encountered robust demand from businesses seeking to enhance revenue growth. Software and business analytics specialist Teradata benefited from the accelerating trend toward “cloud computing,” in which businesses manage data and applications over the Internet.The fund also benefited from underweighted exposure to large, slower-growing technology companies such as Microsoft—and no exposure to Cisco Systems—that appear to have missed the cloud computing trend.

The health care sector led the S&P 500 Index during the reporting period, and the fund achieved above-average returns in the sector

through successful stock selections. Holdings such as Baxter International, Covidien, Zimmer Holdings and Agilent Technologies bounced back from previous weakness as industry utilization rates increased and investors flocked to traditionally defensive investments. Drug producer Watson Pharmaceuticals advanced after capturing market share and receiving approvals for a number of new generic medicines. In the energy sector, overweighted exposure to natural gas producers bolstered results as commodity prices climbed, benefiting companies such as QEP Resources and Southwestern Energy. Investors responded positively to Plains Exploration & Production Company’s announcement of the sale of its deep-water properties in the Gulf of Mexico, and Halliburton gained value as drilling activity intensified.

Seeking Opportunities in a Choppy Economic Recovery

We expect the U.S. economic rebound to persist fitfully amid significant headwinds over the remainder of 2011, leading us to conclude that investors will continue to favor large-cap companies with solid business fundamentals and strong growth prospects.We have found a number of opportunities in the energy and information technology sectors, but fewer in the consumer staples, utilities and telecommunications services sectors.

NOTE 1—Significant Accounting Policies:

Dreyfus Large Cap Equity Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering ten series, including the fund. The fund’s investment objective is to seek long-term 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 Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares.The fund is authorized to issue 250 million shares of $.001 par value Common Stock.The fund currently offers three Classes of shares: Class A (100 million shares authorized), Class C (50 million shares authorized) and Class I (100 million shares authorized). Class A shares are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to 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.

As of June 30, 2011, MBC Investments Corp., an indirect subsidiary of BNY Mellon, held 904 Class C shares of the fund.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (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, 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 Directors. 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 Directors, 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. Options, which are traded on an exchange, are valued at the last sales price on the securities exchange on which such securities are primarily traded or at the last sales price on the national securities market on each business day. Options traded over-the-counter are valued at the mean between the bid and asked price.


The Fund	21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 following is a summary of the inputs used as of June 30, 2011 in valuing the fund’s investments:


		Level 2—Other	Level 3—

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 June 30, 2011.

(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.

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 rights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended June 30, 2011, The Bank of New York Mellon earned $816 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.

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.

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

The fund has an unused capital loss carryover of $70,327,360, 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, the carryover expires in fiscal 2017.

The tax character of distributions paid to shareholders during the fiscal year ended December 31, 2010 was as follows: ordinary income $2,336,477.The tax character of the current year distributions will be determined at the end of the current fiscal year.

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

The Manager had contractually agreed, until May 1, 2011, to waive receipt of its fees and/or assume the expenses of the fund so that the direct expenses of Class I shares (excluding taxes, interest, brokerage commissions, commitment fees on borrowings and extraordinary expenses) did not exceed .79% of the value of Class I shares average daily net assets.

In addition, the Manager had agreed, until May 1, 2011, to waive receipt of its fees and/or assume the expenses of the fund so that the direct expenses of Class A and Class C shares (excluding taxes, interest, brokerage commissions, commitment fees on borrowings, extraordinary expenses, shareholder services fees and Rule 12b-1 fees) did not exceed 1.25% of the value of Class A and Class C shares average daily net assets.

The reduction in expenses, pursuant to the undertakings, amounted to $15,930 during the period ended June 30, 2011.

During the period ended June 30, 2011, the Distributor retained $294 from commissions earned on sales of the fund’s Class A shares.

(c) Under the Shareholder Services Plan, Class A and Class C shares pay the Distributor at an annual rate of .25% of the value of their average daily net assets for the provision of certain services.The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts.The Distributor may make payments to Service Agents (a securities dealer, financial institution or other industry professional) in respect of these services.The Distributor determines the amounts to be paid to Service Agents. During the period ended June 30, 2011, Class A and Class C shares were charged $706 and $94, respectively, pursuant to the Shareholder Services 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 June 30, 2011, the fund was charged $6,327 pursuant to the transfer agency agreement, which is included in Shareholder servicing costs in the Statement of Operations.


The Fund	27

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 June 30, 2011, the fund was charged $944 pursuant to the cash management agreement, which is included in Shareholder servicing costs in the Statement of Operations.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and options transactions, during the period ended June 30, 2011, amounted to $46,891,623 and $59,773,114, respectively.

Options: The fund purchases and writes (sells) put and call options to hedge against changes in the values of equities, or as a substitute for an investment.The fund is subject to market risk in the course of pursuing its investment objectives through its investments in options contracts.A

call option gives the purchaser of the option the right (but not the obligation) to buy, and obligates the writer to sell, the underlying security or securities at the exercise price at any time during the option period, or at a specified date. Conversely, a put option gives the purchaser of the option the right (but not the obligation) to sell, and obligates the writer to buy the underlying security or securities at the exercise price at any time during the option period, or at a specified date.

As a writer of call options, the fund receives a premium at the outset and then bears the market risk of unfavorable changes in the price of the financial instrument underlying the option. Generally, the fund realizes a gain, to the extent of the premium, if the price of the underlying financial instrument decreases between the date the option is written and the date on which the option is terminated. Generally, the fund incurs a loss, if the price of the financial instrument increases between those dates.

As a writer of put options, the fund receives a premium at the outset and then bears the market risk of unfavorable changes in the price of the financial instrument underlying the option. Generally, the fund realizes a gain, to the extent of the premium, if the price of the underlying financial instrument increases between the date the option is written and the date on which the option is terminated. Generally, the fund incurs a loss, if the price of the financial instrument decreases between those dates.

As a writer of an option, the fund has no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the security underlying the written option.There is a risk of loss from a change in value of such options which may exceed the related premiums received. One risk of holding a put or a call option is that if the option is not sold or exercised prior to its expiration, it becomes worthless. However, this risk is limited to the premium paid by the fund. Upon the expiration or closing of the option transaction, a gain or loss is reported in the Statement of Operations.

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large Cap Growth Fund, covering the six-month period from January 1, 2011, through June 30, 2011. 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

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2011, through June 30, 2011, as provided by Irene D. O’Neill, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended June 30, 2011, Dreyfus Large Cap Growth Fund’s Class A shares produced a total return of 6.55%, Class C shares returned 6.15% and Class I shares returned 6.88%.¹In comparison, the Russell 1000 Growth Index (the “Index”), the fund’s benchmark, achieved a total return of 6.83%.²

Although stocks rallied early in the year as an economic recovery appeared to gain traction, renewed concerns later caused the market to give back some of its previous gains.The fund’s returns were roughly in line with its benchmark, as strong performance in the information technology, materials and industrials sectors was balanced by shortfalls in the consumer discretionary, financials and energy sectors.

The Fund’s Investment Approach

The fund invests primarily in large, established companies that we believe have proven track records and the potential for superior relative earnings growth.The investment process begins with a “top-down” assessment of broad economic, political and social trends and their implications for different market and industry sectors. Fundamental research is used to identify companies with the potential for accelerating earnings and revenue growth, favorable market positions, improving operating efficiencies, and/or increasing earnings per share.

Shifting Sentiment Sparked Heightened Volatility


The Fund	3

DISCUSSION OF FUND PERFORMANCE (continued)

interrupted in February when political unrest in North Africa/Middle East led to sharply rising energy prices, and in March when devastating natural and nuclear disasters in Japan threatened one of the world’s largest economies. Nonetheless, investors proved resilient, and stocks bounced back from these unexpected shocks.

In late April, investor sentiment began to deteriorate in earnest when Greece appeared headed for default on its sovereign debt and a contentious debate regarding U.S. government spending and borrowing intensified. Stocks suffered bouts of heightened volatility as newly risk-averse investors shifted their focus from economically sensitive industry groups to those that historically have held up well under uncertain economic conditions.

Security Selections Produced Mixed Results

The fund’s investments in the information technology sector produced particularly strong relative performance due to solid stock selection. Successful stock selections included semiconductor manufacturer ARM Holdings, which advanced due to greater adoption of smartphones containing its microchips. Software and business analytics specialist Teradata and communications equipment maker Acme Packet benefited from the trend toward “cloud computing,” in which businesses manage data and applications over the Internet. Search engine Baidu grew more rapidly after Google’s exit from the Chinese market. The fund also benefited from underweighted exposure to large technology companies—and no exposure to Cisco Systems—that appear to have missed the cloud computing trend.

Results in the materials sector were boosted by iron ore producer Cliffs Natural Resources, which benefited from the industry’s limited mining capacity and a change in the pricing methodology for iron ore.Among industrial companies, aerospace giants Honeywell International and Boeing encountered rising orders for commercial aircraft, while heavy equipment maker Caterpillar and transportation company Union Pacific benefited from improved domestic industrial production trends. In the health care sector, holdings such as Baxter International, Covidien, Zimmer Holdings and Agilent Technologies bounced back from previous weakness as industry utilization rates improved. Drug producer Watson Pharmaceuticals advanced after capturing market share and receiving approvals for a number of new generic medicines.

Disappointments during the reporting period were concentrated mainly in the consumer discretionary sector, where cruise line Carnival suffered when oil prices climbed and itineraries needed to be rerouted due to political instability in North Africa. In addition, mass merchandiser Target was hurt by weaker consumer spending among its customer base. Results from the financials sector were hindered by municipal bond insurer Assured Guaranty, which suffered when a major bond rating agency changed its evaluation methodologies, and by banking giant Citigroup, which was hurt by volatile capital markets and concerns regarding regulatory capital requirements. In the energy sector, Forest Oil lagged amid disappointing production volumes at some of its properties, and Newfield Exploration was punished when investors worried that the company overpaid for a recent acquisition.

Seeking Opportunities in a Choppy Economic Recovery

We expect the U.S. economic rebound to persist fitfully amid significant headwinds over the remainder of 2011, leading us to conclude that investors will continue to favor large-cap companies with solid business fundamentals and strong growth prospects.We have found a number of opportunities in the energy and information technology sectors, but fewer in the consumer discretionary, utilities and telecommunications services sectors.

FINANCIAL HIGHLIGHTS

Please note that the financial highlights information in the following tables for the fund’s Class A and Class I shares represents the financial highlights of the Class A and Institutional shares, repectively, of the fund’s predecessor, BNY Hamilton Large Cap Growth Fund (“Hamilton Large Cap Growth Fund”), before the fund commenced operations as of the close of business on September 12, 2008, and represents the performance of the fund’s Class A and Class I shares thereafter. Before the fund commenced operations, all of the assets of the Hamilton Large Cap Growth Fund were transferred to the fund in exchange for Class A and Class I shares of the fund in a tax-free reorganization. Total return shows how much your investment in the fund would have increased (or decreased) during each period, assuming you had reinvested all dividends and distributions.These figures have been derived from the fund’s and the fund’s predecessor’s financial statements.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus Large Cap Growth Fund (the “fund”) is a separate diversified series of Dreyfus Premier Investment Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company currently offering ten series, including the fund. The fund’s investment objective seeks to provide long-term 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 Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, is the distributor of the fund’s shares. The fund is authorized to issue 250 million shares of $.001 par value Common Stock. The fund currently offers three Classes of shares: Class A (100 million shares authorized), Class C (50 million shares authorized) and Class I (100 million shares authorized). Class A shares are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to 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.

asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board of Directors. 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 Directors, 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. Financial futures and options, which are traded on an exchange, are valued at the last sales price on the securities exchange on which such securities are primarily traded or at the last sales price on the national securities market on each business day. Options traded over-the-counter are valued at the mean between the bid and asked price.


The Fund	21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 following is a summary of the inputs used as of June 30, 2011 in valuing the fund’s investments:


		Level 2—Other	Level 3—

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 rights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended June 30, 2011, The Bank of New York Mellon earned $499 from lending portfolio securities, pursuant to the securities lending agreement.

The Fund

A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus Large Cap Value Fund, covering the six-month period from January 1, 2011, through June 30, 2011. 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
July 15, 2011

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2011, through June 30, 2011, as provided by Brian Ferguson, Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended June 30, 2011, Dreyfus Large Cap Value Fund’s Class A shares produced a total return of 5.09%, Class C shares returned 4.67% and Class I shares returned 5.34%.¹In comparison, the fund’s benchmark, the Russell 1000 Value Index (the “Index”), produced a total return of 5.92% for the same period.²

Stocks generally rallied early in the year as an economic recovery appeared to gain traction, but renewed concerns later caused the market to give back some of its previous gains.The fund produced returns that were lower than its benchmark, as a result of lagging returns from the consumer discretionary and energy sectors.

The Fund’s Investment Approach

The fund seeks to provide long-term capital appreciation; its secondary goal is current income. To pursue these goals, the fund normally invests at least 80% of its assets in equity securities of large capitalization companies with market capitalizations of $5 billion or more at the time of purchase.The fund invests primarily in equity securities of U.S. issuers, but may invest up to 20% of its assets in equity securities of foreign issuers, including those in emerging markets.

When choosing stocks, we focus on individual stock selection (a “bottom-up” approach) rather than forecasting stock market trends. We employ a three-step value screening process that seeks to identify the stocks of companies that are underpriced relative to their intrinsic worth or business prospects, and that exhibit sound business fundamentals, positive business momentum or a catalyst that may trigger an improving stock price.

Shifting Sentiment Sparked Heightened Market Volatility

Investors had become more optimistic by the start of 2011 due to gains in employment, consumer spending and corporate earnings, sending stock prices broadly higher. However, the market rally was interrupted


The Fund	3

DISCUSSION OF FUND PERFORMANCE (continued)

in February when political unrest in the Middle East led to sharply rising crude oil prices, and again in March when catastrophic natural and nuclear disasters in Japan threatened one of the world’s largest domestic economies and disrupted industrial supply chains in the global economy. Nonetheless, investors proved resilient, and the U.S. stock market rebounded from these unexpected shocks.

However, investor sentiment deteriorated in earnest in late April and May when Greece again appeared headed for default on its sovereign debt, U.S. economic data proved more disappointing than expected and a contentious debate regarding U.S. government spending and borrowing intensified. Stocks suffered bouts of heightened volatility as newly risk-averse investors shifted their focus from economically sensitive industry groups to those that historically have held up well under uncertain economic conditions. Value-oriented stocks produced slightly lower returns, on average, than growth-oriented stocks over the first half of the year.

Stock Selections Produced Mixed Results

In this choppy market environment, our security selection strategy proved especially successful in the information technology sector, where video game maker Electronic Arts achieved better-than-expected financial results at the start of a new product cycle centered on digital downloads of gaming software. In the corporate technology market, enterprise systems management specialist BMC Software and data warehousing provider Teradata benefited from the growing trend toward “cloud computing,” in which businesses manage applications and data over the Internet. Consulting services provider Accenture also advanced as more businesses sought help in building corporate data centers for cloud computing.

In the financials sector, bond rating agency Moody’s benefited as corporate bond issuance increased and litigation concerns waned in the wake of the 2008 financial crisis. Investment manager Franklin Resources gained value due to positive asset inflows to the company’s mutual funds, which helped boost profit margins.

Disappointments over the first half of 2011 included the consumer discretionary sector, where cruise line Carnival suffered shortfalls

stemming from higher fuel costs and the need to reroute itineraries in the Mediterranean to avoid political unrest in Northern Africa. Retailer Staples was hurt by sluggish demand for office supplies and intensifying competitive pressures. Apparel seller Guess? encountered lower same-store sales and weaker store traffic. In the energy sector, coal supplier Alpha Natural Resources declined due to higher input prices.

Finding Opportunities Among Quality Companies

Despite ongoing headwinds, we believe the economic recovery is likely to persist. Profits in some industries have returned to pre-recession levels, energy prices have begun to moderate and rebuilding in Japan could boost economic activity.

In this slow-growth environment, we expect investors to remain selective, favoring attractively valued companies with the ability to grow in a sluggish economy and avoiding those with more expensive valuations and weaker underlying business fundamentals. Our bottom-up security selection process has identified a number of opportunities in the consumer discretionary sector, where valuations of media companies appear especially attractive. Fewer stocks in the financials sector have satisfied our value-oriented investment criteria.

	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.
1	Total return includes reinvestment of dividends and any capital gains paid, and does not take into
	consideration the maximum initial sales charges in the case of Class A shares or the applicable
	contingent deferred sales charges imposed on redemptions in the case of Class B and Class C
	shares. Had these charges been reflected, returns would have been lower. 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. Return figures provided reflect the
	absorption of certain fund expenses by The Dreyfus Corporation pursuant to an agreement
	through May 1, 2012, at which time it may be extended, terminated or modified. Had these
	expenses not been absorbed, the fund’s returns would have been lower.
2	SOURCE: LIPPER INC. — Reflects the reinvestment of dividends and, where applicable,

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. Effective May 2, 2011, the fund is closed to any investments for new accounts.

Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class I shares are sold at net asset value per share only to institutional investors. Other differences between the classes include the services offered to 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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 Directors, 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.

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 following is a summary of the inputs used as of June 30, 2011 in valuing the fund’s investments:

fair value hierarchy: quantitative information about the unobservable inputs used in the fair value measurement, the valuation processes used by the reporting entity and a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs. In addition, ASU No. 2011-04 will require reporting entities to make disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. The new and revised disclosures are effective for interim and annual reporting periods beginning after December 15, 2011. At this time, management is evaluating the implications of ASU No. 2011-04 and its impact on the financial statements.

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 rights in, the securities loaned should a borrower fail to return the securities in a timely manner. During the period ended June 30, 2011, The Bank of New York Mellon earned $968 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.

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.
