U.S. Economy Continued to Expand Slowly

The year 2016 began in the midst of an economic slowdown in China, plunging commodity prices, and global stock market declines. Yet, U.S. economic data remained positive in February when the unemployment rate stayed steady at 4.9% and 242,000 jobs were created. In March, manufacturing activity expanded for the first time in six months, but the unemployment rate moved higher to 5.0% despite the creation of 186,000 new jobs. The U.S. economy grew at a 1.1% annualized rate during the first quarter of 2016.

April saw 144,000 new jobs and an unchanged unemployment rate. Manufacturing and utility output advanced strongly, and inflation accelerated amid recovering energy prices. Economic data was mixed in May when only 24,000 new jobs were created while the unemployment rate declined to 4.7% as workers left the labor force. Investors remained cautious in June due to uncertainty surrounding a referendum in Great Britain to leave the European Union. Meanwhile, a robust 271,000 jobs were created during the month, and the unemployment rate increased to 4.9%. Still, U.S. GDP grew at only a 1.4% annualized rate over the second quarter.

Robust job growth continued in July with the addition of 252,000 positions and an unchanged unemployment rate. The manufacturing and services sectors continued to expand, but at slower rates. August brought some disappointing economic news, including a decline in new job creation to 176,000 positions and a contraction in manufacturing activity. In September, 249,000 new jobs were added even as the unemployment rate climbed to 5.0%. U.S. GDP grew at a relatively robust 3.5% annualized rate for the third quarter overall.

Despite political uncertainty ahead of the U.S. election, economic data generally remained positive in October. The unemployment rate slid lower to 4.9% as an estimated 124,000 jobs were created and quarterly corporate earnings exceeded most analysts’ expectations. November saw a post-election rally in most financial markets when investors looked forward to more stimulative fiscal and tax policies from a new presidential administration. Consumer confidence rose to its highest level since July 2007, and the unemployment rate slid to 4.6% while 164,000 new jobs were created.

The Federal Reserve Board (the “Fed”) implemented its only rate hike of the reporting period in December, raising the federal funds rate by 0.25 percentage points to between 0.50% and 0.75% in response to labor market gains and an expected acceleration of inflation. The unemployment rate ticked up to end the year at 4.7%, and 156,000 jobs were created during the month. In addition, consumer confidence continued to improve. U.S. GDP growth moderated to an estimated 1.9% annualized rate during the fourth quarter as declining export activity partly offset gains in consumer spending.

In January 2017, the economy added 227,000 new jobs, but the unemployment rate ticked higher to 4.8%. Meanwhile,

both manufacturing and non-manufacturing activity continued to expand.

More Rate Hikes Expected

As of the reporting period’s end, a new presidential administration’s business-friendly agenda is widely expected to fuel greater economic growth and rising inflationary pressures. Therefore, most analysts expect the Fed to raise short-term rates further in 2017, and we have maintained the funds’ weighted average maturities in ranges that are modestly shorter than industry averages. As always, we have retained our longstanding focus on quality and liquidity.

An investment in the funds is not insured or guaranteed by the FDIC or any other government agency. Each fund, except Dreyfus Cash Management, seeks to preserve the value of your investment at $1.00 per share. Dreyfus Cash Management calculates its net asset value (NAV) to four decimals (e.g., $1.0000), and the fund's NAV “floats,” meaning that it fluctuates with changes in the values of the fund’s portfolio securities. It is possible to lose money by investing in any of the funds.

Short-term corporate, asset-backed securities holdings and municipal securities holdings (as applicable) involve credit and liquidity risks and risk of principal loss.

¹Effective yield is based upon dividends declared daily and reinvested monthly. Past performance is no guarantee of future results. Yields fluctuate.

²Yields provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking, which is voluntary and temporary, not contractual, and can be terminated at any time without notice. Had these expenses not been absorbed, fund yields would have been lower and, in some cases, seven-day yields during the reporting period would have been negative absent the expense absorption.

Dear Shareholder:

Yields of municipal money market instruments climbed over much of the reporting period in response to changing supply-and-demand dynamics and expectations of higher short-term interest rates from the Federal Reserve Board (the “Fed”).

As of October 10, 2016, Dreyfus New York Municipal Cash Management and Dreyfus Tax-Exempt Cash Management were renamed Dreyfus AMT-Free New York Municipal Cash Management and Dreyfus AMT-Free Tax-Exempt Cash Management, respectively.

As of January 17, 2017, Dreyfus Municipal Cash Management Plus was renamed Dreyfus AMT-Free Municipal Cash Management Plus.

Supply-and-Demand Factors Drove Yields Higher

Early in the reporting period, persistent global economic challenges and sharp declines in commodity prices triggered a worldwide flight to traditional safe havens, such as U.S. Treasury securities and municipal bonds. Robust investor demand caused high-quality U.S. bond yields to fall even after the Fed raised short-term interest rates by 25 basis points in December 2015.

These yield levels persisted into the spring of 2016, when supply-and-demand dynamics caused yields of one-year notes and variable rate demand notes (VRDNs) to begin to rise. Demand for tax-exempt money market instruments fell significantly in anticipation of money market reforms slated to take effect in October, but issuance volumes increased from states and local authorities entering the market with one-year note financings. These developments put significant upward pressure on short-term yields. Yields of one-year notes climbed further in the weeks following U.S. elections in November, when investors revised upward their expectations for U.S. economic growth, inflation, and interest rates in anticipation of changing fiscal, tax, and regulatory policies from a new presidential administration. In contrast, yields of seven-day VRDNs remained relatively stable over the final three months of the reporting period.

Despite some isolated pockets of concern, fiscal conditions for tax-exempt issuers generally have remained favorable as municipal credit quality appears to have stabilized after years of gradual improvement. This is particularly evident at the state government level, where replenished rainy day emergency funds may provide a cushion against future economic downturns. In addition, tax receipts for most states have surpassed pre-recession levels. In particular, New York and California have participated fully in the economic recovery, enabling them to achieve budget surpluses.

Maintaining a Prudent Investment Posture

In this environment, most municipal money market funds maintained historically short weighted average maturities with a focus on liquidity. The funds were no exception, as we set their weighted average maturities in ranges that are consistent with industry averages. Indeed, the funds’ short weighted average maturities helped them capture higher yields more quickly.

We also have maintained a careful and well-researched credit selection strategy. We have focused mainly on instruments with strong liquidity characteristics, including VRDNs, and we have emphasized broad diversification across municipal issuers and instruments backed by third parties. In our judgment, many 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 healthcare and education issuers should remain stable credits.

More Rate Hikes Expected

While it remains to be seen if the new presidential administration’s fiscal and tax proposals will be enacted into law, many investors currently expect higher government spending and a friendlier business environment. In addition, in December the Fed implemented its only rate hike of the reporting period by raising the federal funds rate by 0.25 percentage points to between 0.50% and 0.75%. The Fed’s statement at the time forecast a steeper path for borrowing costs in 2017 due to an increase in inflation expectations. The statement also suggested that the U.S. labor market and economic activity were likely to continue to expand.

5

While most analysts expect additional rate hikes in 2017, we believe that any increases are likely to be modest. Therefore, in our view, an emphasis on preservation of capital and liquidity remains the prudent course for the funds’ management.

An investment in the funds is not insured or guaranteed by the FDIC or any other government agency. Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus AMT-Free New York Municipal Cash Management and Dreyfus California AMT-Free Municipal Cash Management seek to preserve the value of your investment at $1.00 per share. Dreyfus AMT-Free Tax Exempt Cash Management calculates its net asset value (NAV) to four decimals (e.g., $1.0000), and the fund's NAV “floats,” meaning that it fluctuates with changes in the values of the fund’s portfolio securities. It is possible to lose money by investing in any of the funds.

Short-term corporate, asset-backed securities holdings and municipal securities holdings (as applicable) involve credit and liquidity risks and risk of principal loss.

¹Effective yield is based upon dividends declared daily and reinvested monthly. Past performance is no guarantee of future results. Yields fluctuate.

²Yields provided reflect the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking, which is voluntary and temporary, not contractual, and can be terminated at any time without notice. Had these expenses not been absorbed, fund yields would have been lower, and in some cases, 7-day yields during the reporting period would have been negative absent the expense absorption.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Cash Management, Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Treasury & Agency Cash Management, Dreyfus Treasury Securities Cash Management, Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus AMT-Free New York Municipal Cash Management, Dreyfus AMT-Free Tax Exempt Cash Management and Dreyfus California AMT-Free Municipal Cash Management (each, a “fund” and collectively, the “funds”) are open-end management investment companies registered under the Investment Company Act of 1940, as amended (the “Act”). Dreyfus Cash Management, Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Treasury & Agency Cash Management, Dreyfus Treasury Securities Cash Management, Dreyfus AMT-Free Municipal Cash Management Plus and Dreyfus AMT-Free Tax Exempt Cash Management are diversified funds. Dreyfus AMT-Free New York Municipal Cash Management and Dreyfus California AMT-Free Municipal Cash Management are non-diversified. Dreyfus Government Cash Management and Dreyfus Government Securities Cash Management are each a separate series of Dreyfus Government Cash Management Funds (the “Company”) and Dreyfus AMT-Free Tax Exempt Cash Management and Dreyfus California AMT-Free Municipal Cash Management are separate series of Dreyfus Tax Exempt Cash Management Funds (the “Trust”).

Each fund’s investment objective is to provide investors with as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. Dreyfus AMT-Free Municipal Cash Management Plus and Dreyfus AMT-Free Tax Exempt Cash Management seek to provide income exempt from federal income taxes and the federal alternative minimum tax. Dreyfus AMT-Free New York Municipal Cash Management seeks to provide income exempt from federal, New York state and New York city income taxes and the federal alternative minimum tax. Dreyfus California AMT-Free Municipal Cash Management seeks to provide income exempt from federal and California state income taxes and the federal alternative minimum tax. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as each fund’s investment adviser.

Effective October 10, 2016, Dreyfus Cash Management and Dreyfus AMT-Free Tax Exempt Cash Management each moved to a “floating” net asset value (NAV) based on the market value of the fund’s portfolio securities, calculated to four decimals.

The Boards of Trustees (each, a “Board” ) of the following funds approved proposals to change the names of such funds, as follows: “Dreyfus Government Prime Cash Management” was changed to “Dreyfus Government Securities Cash Management” effective April 15, 2016; “Dreyfus Treasury Prime Cash Management” was changed to “Dreyfus Treasury Securities Cash Management” effective April 15, 2016; “Dreyfus New York Municipal Cash Management” was changed to “Dreyfus AMT-Free New York Municipal Cash Management” effective October 10, 2016; “Dreyfus Tax-Exempt Cash Management” was changed to “Dreyfus AMT-Free Tax-Exempt Cash Management” effective October 10, 2016; and “Dreyfus Municipal Cash Management Plus” was changed to “Dreyfus AMT-Free Municipal Cash Management Plus” effective January 17, 2017.

The Board of Dreyfus Treasury & Agency Cash Management approved the termination of the fund’s Service Shares and Select Shares, effective March 1, 2016.

The Board of Dreyfus Tax Exempt Cash Management Funds approved the termination of the Administrative Shares of Dreyfus California AMT-Free Tax-Exempt Cash Management, effective April 29, 2016.

As of the close of business on June 19, 2015, pursuant to an Agreement and Plan of Reorganization previously approved by the Board, all of the assets, subject to the liabilities, of Touchstone Institutional Money Market Fund were transferred to Dreyfus Cash Management in exchange for shares of Beneficial Interest of equal value. The purpose of the transaction was to combine two funds with comparable investment objectives and strategies. Shareholders of Touchstone Institutional Money Market Fund received Dreyfus Cash Management Institutional Shares in an amount equal to the aggregate net asset value of their investment in Touchstone Institutional Money Market Fund at the time of the exchange. The net asset value of Dreyfus Cash Management’s shares on the close of business on June 19, 2015, after the reorganization was $1.00, and a total of 518,912,697 shares were issued to shareholders of Touchstone Institutional Money Market Fund in the exchange.

As of the close of business on September 4, 2015, pursuant to an Agreement and Plan of Reorganization previously approved by the Board, all of the assets, subject to the liabilities, of Dreyfus New York AMT-Free Municipal Cash Management were transferred to Dreyfus New York Municipal Cash Management in exchange for shares of Beneficial Interest of equal value. The purpose of the transaction was to combine two funds with comparable investment objectives and strategies. Shareholders of Dreyfus New York AMT-Free Municipal Cash Management’s Institutional, Investor, Administrative and Classic Shares received Dreyfus New York Municipal Cash Management Institutional, Investor, Administrative and Participant Shares,

56

respectively, in an amount equal to the aggregate net asset value of their investment in Dreyfus New York AMT-Free Municipal Cash Management at the time of the exchange. The net asset value of Dreyfus New York Municipal Cash Management’s shares on the close of business on September 4, 2015, after the reorganization was $1.00, and a total of 20,719,739 Institutional, 18,378,257 Investor, 0 Administrative and 23,612 Participant Shares were issued to shareholders of Dreyfus New York AMT-Free Municipal Cash Management in the exchange.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of Dreyfus, is the distributor of each fund’s shares, which are sold to the public without a sales charge. Each fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest. Each fund offers Institutional Shares, Investor Shares, Administrative Shares, Participant Shares and Agency Shares with the exception of Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus AMT-Free New York Municipal Cash Management, Dreyfus AMT-Free Tax Exempt Cash Management and Dreyfus California AMT-Free Municipal Cash Management which do not offer Agency Shares. Dreyfus California AMT-Free Municipal Cash Management does not offer Administrative Shares. In addition, Dreyfus Treasury & Agency Cash Management offers Premier Shares. Each share class, except Institutional Shares, is subject to a Service Plan adopted pursuant to Rule 12b-1 under the Act. Other differences between the classes include the services offered (by Service Agents receiving Rule 12b-1 fees) 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.

Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus AMT-Free New York Municipal Cash Management and Dreyfus California AMT-Free Tax-Exempt Cash Management each operate as a “retail money market fund” as that term is defined in Rule 2a-7 under the Act (a “Retail Fund”). Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Treasury & Agency Cash Management and Dreyfus Treasury Securities each operate as a “government money market fund” as that term is defined in Rule 2a-7 under the Act (a “Government Fund”). It is the policy of each Government Fund and Retail Fund to maintain a constant NAV of $1.00 per share, and each Government Fund and Retail Fund has adopted certain investment, portfolio valuation and dividend and distribution policies to enable it to do so. There is no assurance, however, that a Government Fund or Retail Fund will be able to maintain a constant NAV of $1.00 per share.

Dreyfus Cash Management and Dreyfus AMT-Free Tax Exempt Cash Management each operate as an institutional prime fund (an “Institutional Fund”), with a floating NAV.

Each Retail Fund and Institutional Fund may, or in certain circumstances, must impose a fee upon the sale of shares or may temporarily suspend redemptions if the fund’s weekly liquid assets fall below required minimums because of market conditions or other factors. Government Funds are not subject to liquidity fees or temporary suspensions of redemptions due to declines in the Funds’ weekly liquid assets.

The Company and the Trust account 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 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 funds enter into contracts that contain a variety of indemnifications. The funds’ maximum exposure under these arrangements is unknown. The funds do not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: 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

57

NOTES TO FINANCIAL STATEMENTS (continued)

disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of each 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 funds’ 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.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value each fund’s investments are as follows:

Retail and Government Funds: 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 Board.

Institutional Funds: Investments in securities are valued each business day by an independent pricing service (the “Service”) approved by the Board. Investments for which quoted bid prices are readily available and are representative of the bid side of the market in the judgment of the Service are valued at the mean between the quoted bid prices (as obtained by the Service from dealers in such securities) and asked prices (as calculated by the Service based upon its evaluation of the market for such securities). Other investments (which constitute a majority of the portfolio securities) are carried at fair value as determined by the Service, based on methods which include consideration of the following: yields or prices of municipal securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. All of the preceding securities are generally categorized within Level 2 of the fair value hierarchy.

The Service is engaged under the general supervision of the Board.

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, but before the funds calculate their net asset value, the funds may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments 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. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For restricted securities where observable inputs are limited, assumptions about market activity and risk are used and are generally categorized within Level 3 of the fair value hierarchy.

At January 31, 2017, all of the securities in each fund were considered Level 2 within the fair value hierarchy.

At January 31, 2017, there were no transfers between levels 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.

Dreyfus AMT-Free New York Municipal Cash Management and Dreyfus California AMT-Free Municipal Cash Management each follow 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 funds.

Dreyfus Cash Management, Dreyfus Government Cash Management and Dreyfus Treasury & Agency Cash Management may enter into repurchase agreements with financial institutions, deemed to be creditworthy by Dreyfus, subject to the seller’s agreement to repurchase and each fund’s agreement to resell such securities at a mutually agreed upon price. Pursuant to the terms of the repurchase agreement, such securities must have an aggregate market value greater than or equal to the terms of the repurchase

58

price plus accrued interest at all times. If the value of the underlying securities falls below the value of the repurchase price plus accrued interest, each fund will require the seller to deposit additional collateral by the next business day. If the request for additional collateral is not met, or the seller defaults on its repurchase obligation, each fund maintains its right to sell the underlying securities at market value and may claim any resulting loss against the seller. The collateral is held on behalf of the fund by the tri-party administrator with respect to any tri-party agreement. Each fund may also jointly enter into one or more repurchase agreements with other Dreyfus-managed funds in accordance with an exemptive order granted by the SEC pursuant to section 17(d) and Rule 17d-1 under the Act. Any joint repurchase agreements must be collateralized fully by U.S. Government securities.

(c) Dividends and distributions to shareholders: It is the policy of each 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 each 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 each fund not to distribute such gains.

(d) Federal income taxes: It is the policy of Dreyfus Cash Management, Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management, Dreyfus Treasury & Agency Cash Management and Dreyfus Treasury Securities Cash Management 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.

It is the policy of Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus AMT-Free New York Municipal Cash Management, Dreyfus AMT-Free Tax Exempt Cash Management and Dreyfus California AMT-Free Municipal Cash Management 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.

For federal income tax purposes, each fund is treated as a separate entity for the purpose of determining such qualification.

As of and during the period ended January 31, 2017, the funds did not have any liabilities for any uncertain tax positions. Each fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statements of Operations. During the period ended January 31, 2017, the funds did not incur any interest or penalties.

Each tax year in the four-year period ended January 31, 2017 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At January 31, 2017, the components of accumulated earnings on a tax basis for each fund were substantially the same as for financial reporting purposes.

Under the Regulated Investment Company Modernization Act of 2010, each fund is permitted to carry forward capital losses for an unlimited period. Furthermore, capital loss carryovers retain their character as either short-term or long-term capital losses.

Table 1summarizes each relevant fund’s accumulated capital loss carryover available for federal income tax purposes to be applied against future net realized capital gains, if any, realized subsequent to January 31, 2017.

Table 2 summarizes each fund’s tax character of distributions paid to shareholders during the fiscal periods ended January 31, 2017 and January 31, 2016.

During the period ended January 31, 2017, as a result of permanent book to tax differences, each identified fund increased accumulated undistributed investment income-net and (decreased) accumulated net realized gain (loss) on investments as summarized in Table 3. These permanent book to tax differences are primarily due to dividend reclassification for each relevant fund. Net assets and net asset value per share were not affected by these reclassifications.

At January 31, 2017, the cost of investments for federal income tax purposes for each fund was substantially the same as the cost for financial reporting purposes (see the Statements of Investments).

NOTE 2—Mangement Fee and Other Transactions with Affiliates:

(a) Pursuant to separate management agreements with Dreyfus, the management fee of each fund is computed at the annual rate of .20% of the value of each fund’s average daily net assets and is payable monthly. For the funds listed in Table 4 below, with the exception of Dreyfus AMT-Free Municipal Cash Management Plus, Dreyfus had agreed, from February 1, 2016 through January 31, 2017, to waive receipt of its fee and/or assume the expenses of each fund so that the direct expenses of the Institutional shares of each fund do not exceed .18% of the value of the respective fund’s average daily net assets, provided that such expense limitation will be implemented for each fund only when the fund’s current gross one-day yield (before deducting fees and expenses from the yield) is 18 basis points or higher. This direct expense limitation was maintained at .18% during the period ended January 31, 2017. Dreyfus had agreed, from August 8, 2016 through January 31, 2017, to waive receipt of its fee and/or assume the expenses of each fund so that the direct expenses of Dreyfus Government Cash Management’s Institutional Shares (in accordance with certain provisions as described above) do not exceed .13% of the value of the fund’s average daily net assets when the fund’s current gross one-day yield is 13 basis points or higher. To the extent that it is necessary for Dreyfus to waive receipt of its management fee (or reimburse a fund’s custody expense), the amount of the waiver will be applied equally to each share class of the fund. These expense limitations and waivers are voluntary, not contractual, and may be terminated by Dreyfus at any time. Dreyfus had also agreed, from June 2, 2016 through January 31, 2017, to assume .10% of management fees for Dreyfus AMT-Free Municipal Cash Management Plus. Table 4 summarizes the reduction in expenses for each fund, pursuant to these undertakings, during the period ended January 31, 2017.

(b) Under each fund’s Service Plan adopted pursuant to Rule 12b-1 under the Act, with respect to each fund’s applicable Investor Shares, Administrative Shares, Participant Shares, Agency Shares and Premier Shares, each fund pays (and with respect to Dreyfus Treasury & Agency Cash Management’s Service Shares and Select Shares paid) the Distributor for distributing such classes of shares, for advertising and marketing and for providing certain services relating to shareholders of the respective class of shares. Investor Shares, Administrative Shares, Participant Shares, Agency Shares and Premier Shares pay the Distributor at annual rates of .25%, .10%, .40%, .06% and .31%, respectively, of the value of the applicable share class’ average daily net assets. Service Shares and Select Shares paid the Distributor as described above at annual rates of .50% and .80%, respectively. These services include answering shareholder inquiries regarding the funds and providing reports and other information and services related to the maintenance of shareholder accounts (“Servicing”). Under the Service Plan, as to each class, the Distributor may make payments to Service Agents with respect to these services. Generally, the Service Agent may provide holders of Investor Shares, Administrative Shares, Participant Shares, Agency Shares and Premier Shares a consolidated statement. The Service Agent will generally also provide the holders of Investor Shares, Participant Shares and/or Premier Shares automated teller check writing privileges and, in the case of Participant Shares and Premier Shares, automated teller machine access and bill paying services. The amount paid under the Service Plan for Servicing is intended to be a “service fee” as defined under the Conduct Rules of the Financial Industry Regulatory Authority (“FINRA”), and at no time will such amount exceed the maximum amount permitted to be paid under the FINRA Conduct Rules as a service fee. The fees payable under the Service Plan are payable without regard to actual expenses incurred.

(c) Each fund has adopted a Shareholder Services Plan with respect to its Institutional Shares. Each fund reimburses the Distributor at an amount not to exceed an annual rate of .25% of the value of each 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 funds and providing reports and other information, and services related to the maintenance of shareholder accounts. Table 7summarizes the amount each fund’s Institutional Shares were charged pursuant to the Shareholder Services Plan during the period ended January 31, 2017.

The funds have arrangements with the transfer agent and the custodian whereby the funds 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 funds include net earnings credits as expense offsets in the Statements of Operations.

Each fund compensatesDreyfus Transfer, Inc., a wholly-owned subsidiary of Dreyfus, under a transfer agency agreement for providing transfer agency and cash management services for the funds. The 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. Table 8 summarizes the amount each fund was charged during the period ended January 31, 2017 for cash management services, which is included in Shareholder servicing costs in the Statements of Operations. Cash management fees were partially offset by earnings credits, also summarized in Table 8.

Each 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 each fund. These fees are determined based on net assets, geographic region and transaction activity. Table 9 summarizes the amount each fund was charged during the period ended January 31, 2017 pursuant to the custody agreement. These fees were partially offset by earnings credits for each relevant fund, also summarized in Table 9.

During the period ended January 31, 2017, each fund was charged $9,717 for services performed by the Chief Compliance Officer and his staff.

NOTE 3—Securities Transactions:

The funds are 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 funds 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. Table 11 summarizes the amounts of purchases and sales of securities engaged in by each relevant fund pursuant to Rule 17a-7 under the Act during the period ended January 31, 2017.

We have audited the accompanying statements of assets and liabilities, including the statements of investments, of Dreyfus Cash Management, Dreyfus Government Cash Management, Dreyfus Government Securities Cash Management (formerly, Dreyfus Government Prime Cash Management), Dreyfus Treasury & Agency Cash Management, Dreyfus Treasury Securities Cash Management (formerly, Dreyfus Treasury Prime Cash Management), Dreyfus AMT-Free Municipal Cash Management Plus (formerly, Dreyfus Municipal Cash Management Plus), Dreyfus AMT-Free New York Municipal Cash Management (formerly, Dreyfus New York Municipal Cash Management), Dreyfus AMT-Free Tax Exempt Cash Management (formerly, Dreyfus Tax Exempt Cash Management) and Dreyfus California AMT-Free Municipal Cash Management (the “Funds”) as of January 31, 2017, and the related statements of operations for the year then ended, the statements 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 Funds’ 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 Funds’ 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 Funds’ 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 January 31, 2017 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 the Funds at January 31, 2017, the results of their operations for the year then ended, the changes in their 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.
