A LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholder:

We present to you this annual report for Dreyfus New Jersey Municipal Money Market Fund, Inc., covering the 12-month period from December 1, 2010, through November 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.

The financial markets proved volatile during the reporting period as investors struggled with persistently sluggish global economic growth and persistent sovereign debt concerns. Consequently, the broad international stock market generally lost value in 2011, while U.S. equities fared far better.Among fixed income assets, the escalating European debt crisis sparked a “flight to quality,” in which investors flocked to traditional safe haven assets, such as U.S. government securities. These developments, along with moderate near-term inflation risks, drove longer-term U.S. government securities sharply higher. Shorter-term U.S. government bonds, however, also advanced, but to a much lesser degree. In addition, municipal bonds also performed well, as robust demand from investors seeking higher relative after-tax yields supported bond prices in a limited supply environment.

The global economic outlook currently remains clouded by uncertainty regarding the ability of European policymakers to contain the region’s debt crisis. Meanwhile, conditions in other parts of the world seem to be improving as inflationary pressures have receded in the emerging markets and consumer confidence has strengthened in the United States.To assess the potential impact of these and other developments on your investments, we encourage you, as always, to speak with your financial advisor.

Thank you for your continued confidence and support.

Chairman and Chief Executive Officer

DISCUSSION OF FUND PERFORMANCE

For the period of December 1, 2010, through November 30, 2011, as provided by Joseph Irace, Senior Portfolio Manager

Fund and Market Performance Overview

For the 12-month period ended November 30, 2011, Dreyfus New Jersey Municipal Money Market Fund produced a yield of 0.00%. Taking into account the effects of compounding, the fund produced an effective yield of 0.00%.¹

Tax-exempt money market yields remained stable at historically low levels during the reporting period as short-term interest rates were unchanged in a faltering U.S. economy.

The Fund’s Investment Approach

The fund’s objective is to seek as high a level of current income exempt from federal and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity.The fund also seeks to maintain a stable $1.00 share price.To pursue its goal, the fund normally invests substantially all of its assets in short-term, high-quality municipal obligations that provide income exempt from federal and New Jersey state personal income taxes. The fund also may invest in high-quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations.

When pursuing the fund’s objective, we employ two primary strategies. First, we attempt to add value by constructing a portfolio of high-quality, tax-exempt money market municipal obligations that provide income exempt from federal and New Jersey state income taxes. Second, we actively manage the fund’s average maturity in anticipation of interest-rate trends and supply-and-demand changes in New Jersey’s short-term municipal marketplace.

For example, if we expect an increase in short-term supply, we may reduce the weighted average maturity of the fund, which should better position the fund to purchase new securities with higher yields, if higher

DISCUSSION OF FUND PERFORMANCE (continued)

yields materialize.Yields tend to rise when there is an increase in new-issue supply competing for investor interest. New securities generally are issued with maturities in the one-year range and tend to lengthen the fund’s weighted average maturity if purchased. If we anticipate limited new-issue supply, we may extend the fund’s average maturity to maintain then-current yields for as long as we think practical. At other times, we try to maintain an average maturity that reflects our view of short-term interest-rate trends and future supply-and-demand considerations.

Yields Stay Steady Despite Shifting Economic Sentiment

Although a U.S. economic recovery seemed to gain momentum early in the reporting period, headwinds intensified in February 2011, when energy prices surged amid unrest in the Middle East, and in March, when natural and nuclear disasters in Japan disrupted the global industrial supply chain. Investor sentiment deteriorated further in late April, when Greece appeared headed for default on its sovereign debt and fiscal pressures mounted for other members of the European Union. In the United States, high unemployment and weak housing markets threatened the economic recovery, and a contentious political debate regarding U.S. government spending and borrowing intensified.

In August, Standard & Poor’s downgraded its credit rating on long-term U.S. debt securities, producing heightened volatility through September. Ironically, U.S. government securities rallied strongly during a “flight to quality” in the wake of the downgrade. October and November saw a partial reversal of this trend, as traditional safe havens gave back some of their previous gains when some macroeconomic concerns seemed to ease.

Throughout the reporting period, and as it has since December 2008, the Federal Reserve Board (the “Fed”) left the overnight federal funds rate in a range between 0% and 0.25%. Consequently, municipal money market yields remained near zero percent.

The supply of newly issued municipal money market instruments trended downward during the reporting period, in part due to political pressure to reduce government spending and borrowing. Meanwhile,

demand remained steady from individuals and institutional investors. From a credit-quality perspective, New Jersey has reduced spending, but lower-than-expected tax receipts in fiscal 2012 could put pressure on the state’s fiscal condition.

A Credit-Conscious Investment Posture

As we have for some time, we have maintained a conservative investment posture during the reporting period, emphasizing direct, high-quality municipal obligations and commercial paper deemed creditworthy by our analysts.We favored instruments backed by pledged tax appropriations or dedicated revenues, but we generally shied away from instruments issued by localities that depend heavily on state aid. We maintained the fund’s weighted average maturity in a range that is slightly longer than industry averages.

Outlook Clouded by Economic Uncertainty

The U.S. and New Jersey economies have continued to grow, but the outlook for 2012 remains cloudy due to uncertainty surrounding the European debt crisis and U.S. fiscal policy. However, the Fed has signaled that it is prepared to maintain short-term interest rates near current levels “at least through mid-2013.”With money market yields likely to remain near historical lows, we believe that the prudent course continues to be an emphasis on preservation of capital and liquidity.

	An investment in the fund is not insured or guaranteed by the FDIC or any other government
	agency.Although the fund seeks to preserve the value of your investment at $1.00 per share, it is
	possible to lose money by investing in the fund.
	Short-term municipal securities holdings involve credit and liquidity risks and risk of principal loss.
1	Effective yield is based upon dividends declared daily and reinvested monthly. Past performance is
	no guarantee of future results.Yields fluctuate. Income may be subject to state and local taxes for
	non-New Jersey residents, and some income may be subject to the federal alternative minimum tax
	(AMT) for certain investors.Yields provided reflect the absorption of certain fund expenses by The
	Dreyfus Corporation pursuant to an undertaking in effect that may be extended, terminated or
	modified at any time. Had these expenses not been absorbed, fund yields would have been lower.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus New Jersey Municipal Money Market Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a non-diversified open-end management investment company.The fund’s investment objective is to seek as high a level of current income exempt from federal and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity. 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 to the public without a sales charge.

It is the fund’s policy to maintain a continuous net asset value per share of $1.00; the fund has adopted certain investment, portfolio valuation and dividend and distribution policies to enable it to do so.There is no assurance, however, that the fund will be able to maintain a stable net asset value per share of $1.00.

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 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 amortized cost in accordance with Rule 2a-7 of the Act, which has been determined by the Board of Directors to represent the fair value of the fund’s investments.

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. For example, money market securities are valued using amortized cost,


The Fund	25

NOTES TO FINANCIAL STATEMENTS (continued)

in accordance with rules under the Act. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected within Level 2 of the fair value hierarchy.

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


	Short-Term
Valuation Inputs	Investments ($)^†
Level 1—Unadjusted Quoted Prices	—
Level 2—Other Significant Observable Inputs	276,013,273
Level 3—Significant Unobservable Inputs	—
Total	276,013,273
† See Statement of Investments for additional detailed categorizations.

In May 2011, FASB issued Accounting Standards Update (“ASU”) No. 2011-04 “Amendments to Achieve Common FairValue Measurement and Disclosure Requirements in GAAP and International Financial Reporting Standards (“IFRS”)” (“ASU 2011-04”). ASU 2011-04 includes common requirements for measurement of and disclosure about fair value between GAAP and IFRS. ASU 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 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 2011-04 and its impact on the financial statements.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and recognized on the accrual basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Cost of investments represents amortized cost.

The fund follows an investment policy of investing primarily in municipal obligations of one state. Economic changes affecting the state and certain of its public bodies and municipalities may affect the ability of issuers within the state to pay interest on, or repay principal of, municipal obligations held by the fund.

(c) Dividends to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. 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.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, which can distribute tax exempt dividends, by complying with the applicable provisions of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended November 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.


The Fund	27

NOTES TO FINANCIAL STATEMENTS (continued)

Each of the tax years in the four-year period ended November 30, 2011 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At November 30, 2011, the components of accumulated earnings on a tax basis were substantially the same as for financial reporting purposes.

The tax character of distributions paid to shareholders during the fiscal periods ended November 30, 2011 and November 30, 2010 were as follows: tax exempt income $66 and $90, and long-term capital gains $2,793 and $0, respectively.

During the period ended November 30, 2011, as a result of permanent book to tax differences, primarily due to the tax treatment for dividend reclassification, the fund increased accumulated undistributed investment income-net by $2,793 and decreased accumulated net realized gain (loss) on investments by the same amount. Net assets and net asset value per share were not affected by this reclassification.

At November 30, 2011, the cost of investments for federal income tax purposes was substantially the same as for financial reporting purposes (see the Statement of Investments).

NOTE 2—Management Fee and Other Transactions With Affiliates:

(a) Pursuant to a management agreement with the Manager, the management fee is computed at the annual rate of .50% of the value of the fund’s average daily net assets and is payable monthly.

The Manager has undertaken to waive receipt of the management fee and/or reimburse operating expenses in order to facilitate a daily yield at or above a certain level which may change from time to time.This undertaking is voluntary and not contractual, and may be terminated at any time. The reduction in expenses, pursuant to the undertaking, amounted to $668,735 during the period ended November 30, 2011.

(b) Under the Shareholder Services Plan, the fund reimburses the Distributor an amount not to exceed an annual rate of .25% of the value of the fund’s average daily net assets for certain allocated expenses of providing personal services and/or maintaining shareholder accounts.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. During the period ended November 30, 2011, the fund was charged $150,593 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 November 30, 2011, the fund was charged $61,788 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, a subsidiary of BNY Mellon and an affiliate of Dreyfus, under a cash management agreement for performing cash management services related to fund subscriptions and redemptions. During the period ended November 30, 2011, the fund was charged $6,305 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 $242.


The Fund	29

NOTES TO FINANCIAL STATEMENTS (continued)

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 November 30, 2011, the fund was charged $27,324 pursuant to the custody agreement.

During the period ended November 30, 2011, the fund was charged $6,356 for services performed by the Chief Compliance Officer.

The components of “Due toThe Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $113,341, custodian fees $9,443, chief compliance officer fees $4,743 and transfer agency per account fees $14,042, which are offset against an expense reimbursement currently in effect in the amount of $70,276.

(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 3—Securities Transactions:

The fund is permitted to purchase or sell securities from or to certain affiliated funds under specified conditions outlined in procedures adopted by the Board of Directors.The procedures have been designed to ensure that any purchase or sale of securities by the fund from or to another fund or portfolio that are, or could be, considered an affiliate by virtue of having a common investment adviser (or affiliated investment adviser), common Directors and/or common officers, complies with Rule 17a-7 of the Act. During the period ended November 30, 2011, the fund engaged in purchases and sales of securities pursuant to Rule 17a-7 of the Act amounting to $211,585,000 and $203,400,000, respectively.

PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors

Dreyfus New Jersey Municipal Money Market Fund, Inc.

We have audited the accompanying statement of assets and liabilities of Dreyfus New Jersey Municipal Money Market Fund, Inc., including the statement of investments, as of November 30, 2011, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and financial highlights for each of the years indicated therein. These financial statements and financial highlights are the responsibility of the Fund’s management. 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 principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2011 by correspondence with the custodian and others.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 New Jersey Municipal Money Market Fund, Inc. at November 30, 2011, 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.

At a meeting of the fund’s Board of Directors held on November 7-8, 2011, the Board considered the renewal of the fund’s Management Agreement with Dreyfus pursuant to which Dreyfus provides the fund with investment advisory and administrative services (the “Agreement”). The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the fund, were assisted in their review by independent legal counsel and met with counsel in executive session separate from Dreyfus representatives. In considering the renewal of the Agreement, the Board considered all factors that it believed to be relevant, including those discussed below.The Board did not identify any one factor as dispositive, and each Board member may have attributed different weights to the factors considered.

Analysis of Nature, Extent and Quality of Services Provided to the Fund.The Board considered information previously provided to them in a presentation from Dreyfus representatives regarding the nature, extent, and quality of the services provided to funds in the Dreyfus fund complex, and representatives of Dreyfus confirmed that there had been no material changes in this information. Dreyfus provided the number of open accounts in the fund, the fund’s asset size and the allocation of fund assets among distribution channels. Dreyfus also had previously provided information regarding the diverse intermediary relationships and distribution channels of funds in the Dreyfus fund complex and Dreyfus’ corresponding need for broad, deep, and diverse resources to be able to provide ongoing shareholder services to each distribution channel, including the distribution channel(s) for the fund.

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

MANAGEMENT AGREEMENT (Unaudited) (continued)

Comparative Analysis of the Fund’s Performance and Management Fee and Expense Ratio.The Board reviewed reports prepared by Lipper, Inc. (“Lipper”), an independent provider of investment company data, which included information comparing (1) the fund’s performance with the performance of a group of comparable funds (the “Performance Group”) and with a broader group of funds (the “Performance Universe”), all for various periods ended September 30, 2011, and (2) the fund’s actual and contractual management fees and total expenses with those of a group of comparable funds (the “Expense Group”) and with a broader group of funds (the “Expense Universe”), the information for which was derived in part from fund financial statements available to Lipper as of September 30, 2011. Dreyfus previously had furnished the Board with a description of the methodology Lipper used to select the Performance Group and Performance Universe and the Expense Group and Expense Universe.

Dreyfus representatives stated that the usefulness of performance comparisons may be affected by a number of factors, including different investment limitations that may be applicable to the fund and comparison funds. The Board discussed the results of the comparisons and noted that the fund’s total return performance was variously below, at, and above the Performance Group median and the Performance Universe median for various time periods.The Board noted that the fund’s performance was only one basis point lower than the applicable Performance Group median or Performance Universe median for the 1-year and 2-year periods.

The Board also reviewed the range of actual and contractual management fees and total expenses of the Expense Group and Expense Universe funds and discussed the results of the comparisons. They noted that the fund’s contractual management fee was above the Expense Group median, the fund’s actual management fee was above the Expense Group median and the Expense Universe median, and the fund’s actual total expenses were above the Expense Group median and the Expense Universe median.

The Board considered the duration and extent of the fee waiver/expense reimbursement undertaking by Dreyfus to support a minimum zero or positive daily yield, as applicable from time to time, in the historically low interest rate environment, and the Board noted the extent to which differences among the returns for the Performance Group funds might be attributable to similar undertakings.

Dreyfus representatives reviewed with the Board the management or investment advisory fees paid to Dreyfus or its affiliates by funds in the same Lipper category as the fund (the “Similar Accounts”), and explained the nature of the Similar Accounts. Dreyfus representatives noted that Dreyfus does not advise any separate accounts and/or other types of client portfolios that are considered to have similar investment strategies and policies as the fund.They discussed differences in fees paid and the relationship of the fees paid in light of any differences in the services provided and other relevant factors.The Board considered the relevance of the fee information provided for the Similar Accounts to evaluate the appropriateness and reasonableness of the fund’s management fee.

Analysis of Profitability and Economies of Scale. Dreyfus’ representatives reviewed the expenses allocated and profit received by Dreyfus and the resulting profitability percentage for managing the fund, and the method used to determine the expenses and profit. The Board concluded that the profitability results were not unreasonable given the services rendered and service levels provided by Dreyfus. The Board also noted the expense limitation arrangement and its effect on Dreyfus’ profitability. The Board previously had been provided with information prepared by an independent consulting firm regarding Dreyfus’ approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus fund complex.The consulting firm also had analyzed where any economies of scale might emerge in connection with the management of a fund.

INFORMATION ABOUT THE RENEWAL OF THE FUND’S

MANAGEMENT AGREEMENT (Unaudited) (continued)

The Board’s counsel stated that the Board should consider the profitability analysis (1) as part of their evaluation of whether the fees under the Agreement bear a reasonable relationship to the mix of services provided by Dreyfus, including the nature, extent, and quality of such services, and (2) 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 shareholders. Dreyfus representatives noted that a discussion of economies of scale is predicated on a fund having achieved a substantial size with increasing assets and that, if a fund’s assets had been stable or decreasing, the possibility that Dreyfus may have realized any economies of scale would be less. Dreyfus representatives also noted that, as a result of shared and allocated costs among funds in the Dreyfus fund complex, the extent of economies of scale could depend substantially on the level of assets in the complex as a whole, so that increases and decreases in complex-wide assets can affect potential economies of scale in a manner that is disproportionate to, or even in the opposite direction from, changes in the fund’s asset level.The Board also considered potential benefits to Dreyfus from acting as investment adviser and noted that there were no soft dollar arrangements in effect for trading the fund’s investments.

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 the renewal of the Agreement. Based on the discussions and considerations as described above, the Board concluded and determined as follows.

The Board concluded that the nature, extent, and quality of the services provided by Dreyfus are adequate and appropriate.
The Board was satisfied with the fund’s performance, in light of the considerations described above.
The Board concluded that the fee paid to Dreyfus was reasonable in light of the considerations described above.

The Board determined that the economies of scale which may accrue to Dreyfus and its affiliates in connection with the management of the fund had been adequately considered by Dreyfus in connection with the fee rate charged to the fund pursuant to the Agreement 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 considered these conclusions and determinations, along with information received on a routine and regular basis throughout the year. In addition, it should be noted that the Board’s consideration of the contractual fee arrangements for this fund had the benefit of a number of years of reviews of prior or similar agreements during which lengthy discussions took place between the Board and Dreyfus representatives. Certain aspects of the arrangements may receive greater scrutiny in some years than in others, and the Board’s conclusions may be based, in part, on their consideration of the same or similar arrangements in prior years.The Board determined that renewal of the Agreement was in the best interests of the fund and its shareholders.
