A LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this annual report for Dreyfus New York AMT-Free Municipal Money Market Fund, Inc., covering the 12-month period from June 1, 2014, through May 31, 2015. 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.

Longer term U.S.Treasury securities fared well over the first half of the reporting period when long-term interest rates fell amid robust demand from global investors, but returns moderated in early 2015 amid heightened market volatility stemming from renewed domestic economic concerns and expectation of higher short-term interest rates in the months ahead.Yet, yields of money market instruments remained steady throughout the reporting period, anchored near zero percent by an unchanged target for overnight interest rates.Yields also experienced downward pressure from robust demand for a relatively limited supply of money market-eligible instruments.

We remain optimistic regarding the outlook for the U.S. economy. We believe the domestic economic recovery has resumed after a winter soft patch, labor markets remain strong, energy prices have climbed from previous lows, and aggressively accommodative monetary policies from the world’s major central banks seem likely to address persistent global economic weakness. Nonetheless, we believe short-term interest rates may remain near current levels at least until later in 2015, and any eventual rate hikes may be gradual and modest. As always, we urge you to discuss these observations with your financial advisor, who can help you assess their implications for your investment portfolio.

Thank you for your continued confidence and support.

J. Charles Cardona
President
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

For the period of June 1, 2014 through May 31, 2015, as provided by Bill Vasiliou, Portfolio Manager

Fund and Market Performance Overview

For the 12-month period ended May 31, 2015, Dreyfus New York AMT-Free Municipal Money Market Fund, Inc. produced a yield of 0.00%. Taking into account the effects of compounding, the fund produced an effective yield of 0.00%.¹

Long-term interest rates encountered heightened volatility during the reporting period, but short-term interest rates stayed steady near historical lows. Consequently, yields of tax-exempt money market instruments remained near zero percent.

The Fund’s Investment Approach

The fund seeks to maximize current income exempt from federal, NewYork state, and NewYork city personal income taxes, to the extent consistent with the preservation of capital and the maintenance of liquidity. To pursue its goal, the fund normally invests substantially all of its net assets in short-term, high-quality municipal obligations that provide income exempt from federal, NewYork state, and NewYork city income taxes. The fund also seeks to provide income exempt from the federal alternative minimum tax. The fund may also invest in high-quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations.

In pursuing this objective, we employ two primary strategies. First, we normally attempt to add value by constructing a diverse portfolio of high-quality, municipal money market instruments that provide income exempt from federal, New York state, and New York city personal income taxes. Second, we actively manage the fund’s average maturity based on our anticipation of supply-and-demand changes in New York’s short-term municipal marketplace.

If we expect an increase in short-term supply, we may decrease the average maturity of the fund, which could enable us to take advantage of opportunities when short-term supply increases.Yields generally tend to rise when there is an increase in new-issue supply competing for investor interest. New securities, which are generally issued with maturities in the one-year range, may in turn lengthen the fund’s average maturity if

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

purchased. If we anticipate limited new-issue supply, we may then look to extend the fund’s average maturity to maintain then-current yields for as long as we believe practical. In addition, we try to maintain an average maturity that reflects our view of short-term interest-rate trends and future supply-and-demand considerations.

Accommodative Fed Policy Kept Yields Low

The U.S. economy recovered strongly over the first half of the reporting period, but long-term interest rates declined due to a supply-and-demand imbalance when global investors flocked to U.S. Treasury securities. This trend began to reverse over the reporting period’s second half: longer term interest rates drifted higher amid stronger-than-expected employment data and expectations of short-term rate hikes later this year.An economic soft patch during the winter of 2015 caused yields to moderate temporarily, but long-term rates resumed their climb when growth re-accelerated in the spring. Despite these developments, short-term rates remained steady as the Federal Reserve Board (the “Fed”) maintained the federal funds rate in a range between 0% and 0.25%.

Meanwhile, investor demand continued to be robust, while the supply of new municipal money market instruments stayed low as the need for short-term financing diminished. Municipal credit quality generally continued to improve when many states and local governments balanced their budgets and replenished reserves. New York participated fully in the national recovery, supported by a strong financial services industry.

Focus on Quality and Liquidity

As we have for some time, we retained the fund’s focus on instruments with strong liquidity characteristics, including variable rate demand notes (VRDNs) on which yields are reset weekly.As part of our risk management strategy, we maintained broad diversification across municipal issuers and instruments backed by third parties. For example, we have identified stable credits among state general obligation bonds; essential-service revenue bonds issued by water, sewer, and electric enterprises; certain local credits with strong financial positions and stable tax bases; and various health care and education issuers.

4

We continued to maintain a short weighted average maturity compared to historical averages, as narrow yield differences along the market’s maturity range provided little incentive to assume the incremental risks of longer dated instruments.

Fed: Neither Patient nor Impatient

The Fed has reiterated that “it will take a balanced approach consistent with its longer-run goals of maximum employment and inflation of 2%,” and “economic conditions may, for some time, warrant keeping the target federal funds rate below levels the Federal Open Market Committee views as normal in the longer run.” Therefore, while many analysts expect rate hikes to begin later this year, those increases are likely to be modest and gradual. Meanwhile, the outlook for higher yields and money market reforms could move the one-year note index off historical lows, and we will carefully monitor the upcoming note issuance season for evidence of this trend.As for now, in our judgment, the prudent course for fund management continues to be an emphasis on preservation of capital and liquidity.

June 15, 2015

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-NewYork residents, and some 

income may be subject to the federal alternative minimum tax (AMT) for non-NewYork residents.Yields provided for 

the fund’s shares reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to a voluntary 

undertaking 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 York AMT-Free Municipal Money Market Fund (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, New York state and New York city 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 Dreyfus, is the distributor of the fund’s shares, which are sold 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.

The Fund 17

NOTES TO FINANCIAL STATEMENTS (continued)

(a) Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 under the Act. If amortized cost is determined not to approximate market value, the fair value of the portfolio securities will be determined by procedures established by and under the general supervision of the fund’s Board of Trustees (the “Board”).

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

18

cost, 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 May 31, 2015 in valuing the fund’s investments:

	Short-Term
Valuation Inputs	Investments ($)†
Level 1—Unadjusted Quoted Prices	—
Level 2—Other Significant Observable Inputs	94,940,806
Level 3—Significant Unobservable Inputs	—
Total	94,940,806

† See Statement of Investments for additional detailed categorizations.

At May 31, 2015, there were no transfers between Level 1 and Level 2 of the fair value hierarchy.

(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 is 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 Fund 19

NOTES TO FINANCIAL STATEMENTS (continued)

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 May 31, 2015, 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 ended May 31, 2015, the fund did not incur any interest or penalties.

At May 31, 2015, the components of accumulated earnings on a tax basis were substantially the same as for financial reporting purposes.

Each tax year in the four-year period ended May 31, 2015 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The tax character of distributions paid to shareholders during the fiscal periods ended May 31, 2015 and May 31, 2014 were all tax-exempt income.

At May 31, 2015, 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 (the “Agreement”) with Dreyfus, 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

20

monthly. The Agreement provides that if in any full fiscal year the aggregate expenses of the fund (excluding taxes, brokerage commissions and extraordinary expenses) exceed 1 ¹ / ₂ % of the value of the fund’s average daily net assets, the fund may deduct from the payment to be made to Dreyfus, or Dreyfus will bear, such excess expense. During the period ended May 31, 2015, there was no reduction in expenses pursuant to the Agreement.

Dreyfus has also 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 $634,433 during the period ended May 31, 2015.

(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 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. During the period ended May 31, 2015, the fund was charged $68,183 pursuant to the Shareholder Services Plan.

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

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of Dreyfus, under a transfer agency agreement for providing transfer agency and cash management services for the fund. The

The Fund 21

NOTES TO FINANCIAL STATEMENTS (continued)

majority of transfer agency fees are comprised of amounts paid on a per account basis, while cash management fees are related to fund subscriptions and redemptions. During the period ended May 31, 2015, the fund was charged $27,788 for transfer agency services and $1,342 for cash management services. These fees are included in Shareholder servicing costs in the Statement of Operations. Cash management fees were partially offset by earnings credits of $59.

The fund compensates The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, under a custody agreement for providing custodial services for the fund.These fees are determined based on net assets, geographic region and transaction activity. During the period ended May 31, 2015, the fund was charged $12,761 pursuant to the custody agreement.

The fund compensates The Bank of New York Mellon for performing certain cash management services related to fund subscriptions and redemptions, including shareholder redemption draft processing, under a cash management agreement. During the period ended May 31, 2015, the fund was charged $1,023 pursuant to the agreement, which is included in Shareholder servicing costs in the Statement of Operations.

During the period ended May 31, 2015, the fund was charged $10,891 for services performed by the Chief Compliance Officer and his staff.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $40,942, Shareholder Services Plan fees $6,000, custodian fees $4,081, Chief Compliance Officer fees $2,113 and transfer agency fees $5,342, which are offset against an expense reimbursement currently in effect in the amount of $47,773.

(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.

22

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.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 Trustees and/or common officers, complies with Rule 17a-7 under the Act. During the period ended May 31, 2015, the fund engaged in purchases and sales of securities pursuant to Rule 17a-7 under the Act amounting to $37,700,000 and $33,670,000, respectively.

NOTE 4—Regulatory Developments:

On July 23, 2014, the SEC adopted amendments to the rules that govern money market mutual funds. In part, the amendments will require structural changes to most types of money market funds to one extent or another; however, the SEC provided for an extended two-year transition period to comply with such structural requirements. At this time, management is evaluating the reforms adopted and the manner for implementing these reforms over time and its impact on the financial statements.

NOTE 5—Subsequent Event:

On July 27, 2015, the Board approved a Plan of Liquidation (the “Plan”).The Plan provides for the liquidation of the fund, the pro rata distribution of the assets of the fund to its shareholders and the closing of fund shareholder accounts (the “Liquidation”). The Liquidation of the fund is expected to occur on or about October 28, 2015. Accordingly, effective August 28, 2015, the fund will be closed to any investments for new accounts.

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

Shareholders and Board of Trustees
Dreyfus New York AMT-Free Municipal Money Market Fund

We have audited the accompanying statement of assets and liabilities of Dreyfus NewYork AMT-Free Municipal Money Market Fund, including the statement of investments, as of May 31, 2015, 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 the financial highlights for each of the five years in the period then ended. 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 May 31, 2015 by correspondence with the custodian.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 York AMT-Free Municipal Money Market Fund at May 31, 2015, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

1.Covered Officers/Purpose of the Code

This code of ethics (the "Code") for the investment companies within the complex (each, a "Fund") applies to each Fund's Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller, or other persons performing similar functions, each of whom is listed on Exhibit A(the "Covered Officers"), for the purpose of promoting:

·honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

·full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the Fund;

·compliance with applicable laws and governmental rules and regulations;

·the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

·accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

2.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund.  For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act"), and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. The compliance programs and procedures of the Fund and the Fund's investment adviser (the "Adviser") are designed to prevent, or identify and correct, violations of these provisions. The Code does not, and is not intended to, repeat or replace these programs and procedures, and the circumstances they cover fall outside of the parameters of the Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the Adviser of which the Covered Officers are also officers or employees.  As a result, the Code recognizes that the Covered Officers, in the ordinary course of their duties (whether formally for the Fund or for the Adviser, or for both), will be involved in establishing policies and implementing decisions that will have different effects on the Adviser and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the Adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Fund and, if addressed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, will be deemed to have been handled ethically. In addition, it is recognized by the Fund's Board that the Covered Officers also may be officers or employees of one or more other investment companies covered by this or other codes of ethics.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act.  Covered Officers should keep in mind that the Code cannot enumerate every possible scenario.  The overarching principle of the Code is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

·not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

·not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund; and

·not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith.

3.Disclosure and Compliance

·Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Fund within his area of responsibility;

·each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board members and auditors, and to governmental regulators and self-regulatory organizations;

·each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Fund and the Adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

·it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

4.Reporting and Accountability

Each Covered Officer must:

·upon adoption of the Code (or thereafter, as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he has received, read, and understands the Code;

·annually thereafter affirm to the Board that he has complied with the requirements of the Code; and

·notify the Adviser's General Counsel (the "General Counsel") promptly if he knows of any violation of the Code.  Failure to do so is itself a violation of the Code.

The General Counsel is responsible for applying the Code to specific situations in which questions are presented under it and has the authority to interpret the Code in any particular situation. However, waivers sought by any Covered Officer will be considered by the Fund's Board.

The Fund will follow these procedures in investigating and enforcing the Code:

·the General Counsel will take all appropriate action to investigate any potential violations reported to him;

·if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

·any matter that the General Counsel believes is a violation will be reported to the Board;

·if the Board concurs that a violation has occurred, it will consider appropriate action, which may include: review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Adviser or its board; or dismissal of the Covered Officer;

·the Board will be responsible for granting waivers, as appropriate; and

·any waivers of or amendments to the Code, to the extent required, will be disclosed as provided by SEC rules.

5.Other Policies and Procedures

The Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. The Fund's, its principal underwriter's and the Adviser's codes of ethics under Rule 17j-1 under the Investment Company Act and the Adviser's additional policies and procedures, including its Code of Conduct, are separate requirements applying to the Covered Officers and others, and are not part of the Code.

6.Amendments 

The Code may not be amended except in written form, which is specifically approved or ratified by a majority vote of the Fund's Board, including a majority of independent Board members.

7.Confidentiality 

All reports and records prepared or maintained pursuant to the Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or the Code, such matters shall not be disclosed to anyone other than the appropriate Funds and their counsel, the appropriate Boards (or Committees) and their counsel and the Adviser. 

8.Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.
