Economic and Market Environment

When the reporting period began, the Federal Reserve Board (the “Fed”) had left short-term interest rates unchanged at 5.25% over the previous seven months in an environment of softening housing markets and declining energy prices. The combination of slowing economic growth and subdued inflation led some investors to believe that the Fed would remain on the sidelines for much of 2007 as it continued to scrutinize new economic data to assess the impact of its previous tightening campaign. In fact, the Fed again held short-term interest rates steady at its meeting in late January, just days before the start of the reporting period.

Despite heightened volatility in equity markets and the emergence of credit problems in the sub-prime mortgage sector in late February, the unemployment rate dipped to 4.5% .This development seemed to ease fears that the long U.S. economic expansion might be ending, as it would be unusual to see pronounced weakness among consumers while the labor market remained robust. The Fed apparently endorsed this view in late March, when it again left the federal funds rate unchanged. However, a change in the wording of its accompanying announcement suggested that the Fed viewed the risk of inflation as greater than the risk of recession, pushing back investors’ expectations of an eventual easing of monetary policy. It later was announced that GDP in the first quarter grew at an anemic 0.7% annualized rate, the slowest quarterly pace since the first quarter of 2003.

Economic and inflation data remained mixed in April and May. On one hand, housing prices continued to slide and consumer sentiment deteriorated. On the other hand, a key measure of inflation, the core personal consumption price index, rose by 2.2% in May before moderating in June. This was above the target rate that many Fed members have stated as the upper limit of their inflation tolerance, reinforcing investors’ views that the Fed was unlikely to reduce short-term interest rates anytime soon.

The Funds 3

LETTER TO SHAREHOLDERS (continued)

In June, signs of stronger economic growth contributed to higher yields on longer-term bonds. In its statement following its Federal Open Market Committee meeting on June 28, the Fed indicated that it was not yet convinced of the sustainability of lower inflationary pressures. In addition, the Fed expressed its view that the economy was likely to expand moderately, and that high levels of resource utilization could lead to higher inflation in the future. It later was estimated that the U.S. GDP grew at an annualized rate of 3.4% in the second quarter of 2007, further evidence of the economy’s resilience in the face of weakening housing markets and resurgent energy prices.

July proved to be a difficult month for the financial markets, when intensifying housing and lending concerns sparked a sharp repricing of risk in the stock and bond markets. Sharp declines in equities and the more credit-sensitive fixed-income sectors occurred when it was reported that rising delinquencies and defaults had spread from the sub-prime mortgage sector to home equity borrowers with good credit histories. Meanwhile, sales of existing homes slid to the slowest pace in almost five years, and sales of new single-family homes dropped by a significantly greater amount than had been expected. Still, by the reporting period’s end, money market instruments remained relatively insulated from the turmoil affecting longer-term securities, as the Fed gave no sign that it was prepared to alter its steady policy stance.

Portfolio Focus

In this relatively uncertain environment, we generally maintained the funds’ weighted average maturity in a range we considered to be in line with industry averages. Later in the reporting period, when it became clearer to us that the Fed would remain on

hold for the time being, we began to increase the funds’ holdings of money market instruments with longer dated maturities in an attempt to capture incrementally higher yields.

At its Federal Open Market Committee meeting soon after the end of the reporting period, the Fed again held the federal funds rate at 5.25% . Although the Fed acknowledged the recent market volatility caused by the sub-prime mortgage crisis, it continued to regard inflation as a more serious risk to the nation’s economic health than potential recession. This outlook was short-lived as the credit markets experienced one of the most significant upheavals in recent memory during mid-August leading the Fed to cut the discount rate.As we write, the Fed has not cut the overnight federal funds rate, but most market participants expect further actions from the Fed in order to facilitate a return to normalcy in the short-term money markets. We will, of course, closely monitor economic and financial conditions and stand ready to make portfolio adjustments as conditions warrant.

SHAREHOLDERS

For the period of February 1, 2007, through July 31, 2007, as provided by Colleen Meehan, Senior Portfolio Manager

Dear Shareholder:

Despite heightened volatility among longer-term bonds, yields of money market instruments remained relatively stable over the reporting period as the Federal Reserve Board (the “Fed”) continued to hold the overnight federal funds rate steady at 5.25% .

For the six-month period ended July 31, 2007, the three tax-exempt money market portfolios that comprise Dreyfus Cash Management Funds (Tax Exempt) produced the following annualized yields and annualized effective yields:¹

Short-Term Interest Rates Remained Steady Despite Volatility Among Longer-Term Bonds

The reporting period was characterized by heightened levels of uncertainty and volatility in the U.S. bond market, stemming primarily from credit concerns in the sub-prime mortgage sector and investors’ shifting expectations regarding domestic economic growth and inflation. In contrast, money market instruments traded within a relatively narrow range as the Fed remained on the sidelines throughout the reporting period.

Although many analysts early in the reporting period anticipated a rate cut from the Fed sometime in 2007, those expectations were delayed by signs of stronger-than-expected economic growth, including a robust labor market and a relatively robust 3.4% annualized GDP growth rate for the second quarter of the year. Inflation concerns were rekindled by resurgent energy prices as crude oil set new record highs, and food prices rose sharply due largely to rising demand for corn, which is increasingly used to manufacture ethanol. Yet, the core rate of inflation appeared to remain relatively mild as weak housing markets, sluggish retail sales of apparel and ongoing troubles in the automotive sector helped to contain consumer prices. Faced with these mixed economic and inflation signals, the Fed risked an acceleration of inflation if it cut interest rates, while further rate hikes might have increased the chances of a more severe economic decline.

With the Fed on hold, the tax-exempt money markets were influenced to a significant degree by supply-and-demand forces. Investment banks continued to create a substantial volume of variable rate demand notes (“VRDNs”) and tender option bonds (“TOBs”), which put upward pressure on yields at the short end of the market’s maturity range. In fact, at times during the reporting period, VRDNs and TOBs provided higher yields than longer-dated municipal notes as a result of the ample supply of floating-rate product. The rest of the yield curve remained relatively flat throughout the reporting period, with little difference in yields among instruments with maturities between six months and one year.

The fiscal conditions of most states and municipalities remained sound during the reporting period.

The Funds 5

LETTER TO SHAREHOLDERS (continued)

Although some states have felt the impact of weak housing markets more than others, tax revenues generally have continued to support balanced budgets for most issuers.As a result, the winter and spring of 2007 was a time of relatively low issuance volumes in the short-term tax-exempt market, with a dearth of newly issued fixed-rate notes contributing to short weighted average maturities throughout our industry. However, the supply of municipal notes increased at least temporarily during June and July as states and municipalities issued their short-term financings for their upcoming fiscal years. Meanwhile, investor demand has been robust as tax-exempt money market assets have remained near record highs so far in 2007.

The fiscal environment in New York proved to be particularly favorable.The state and city continued to benefit from strong conditions in the financial services industry.The City of New York received a credit rating upgrade from one of the major bond rating agencies during the reporting period, and the City now enjoys the highest credit rating in its history.

A Conservative Investment Posture Was Warranted in an Uncertain Market

In this market environment, we generally have maintained the funds’ weighted average maturities in a range that is in line with to slightly longer than industry averages. We have focused primarily on VRDNs, complementing those holdings with tax-exempt commercial paper and seasoned municipal notes with maturities between three and nine months. We have attempted to “ladder” the funds’ longer-dated holdings so that their maturities are staggered, a strategy that is designed to stabilize the funds’ yields and protect them from unexpected fluctuations in short-term interest rates.

As always, we have maintained conservative credit standards, which we believe has become more important due to the recent spread of credit concerns from the sub-prime mortgage sector to other credit-sensitive areas of the bond market.

As of the reporting period’s end, we have seen no sign that the Fed is prepared to alter its policy stance. The U.S. economy has continued to send mixed signals, suggesting to us that current market uncertainty may persist. In addition, tax-exempt yield spreads have remained narrow compared to historical norms. Therefore, we have continued to maintain the funds’ average weighted maturities in a range that is close to industry averages.

NOTE 1—Significant Accounting Policies:

Dreyfus Cash Management, Dreyfus Cash Management Plus, Inc., Dreyfus Government Cash Management, Dreyfus Government Prime Cash Management, Dreyfus Treasury Cash Management, Dreyfus Treasury Prime Cash Management, Dreyfus Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax Exempt 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”). Each fund, other than Dreyfus New York Municipal Cash Management, is diversified. Dreyfus New York Municipal Cash Management is non-diversified. Dreyfus Government Cash Management and Dreyfus Government Prime Cash Management are each a separate series of Dreyfus Government Cash Management Funds (the “Company”) which currently offers two series. Dreyfus Tax Exempt Cash Management is a series of Dreyfus Tax Exempt Cash Management Funds, which also currently offers two series. 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 and, in the case of Dreyfus Municipal Cash Management Plus and Dreyfus Tax Exempt Cash Management only, which is exempt from federal income tax, and, in the case of Dreyfus New York Municipal Cash Management only, which are exempt from federal, New York state and New York city personal income taxes. The Dreyfus Corporation (the “Manager” or “Dreyfus”) serves as each fund’s investment adviser. During the reporting period, the Manager was a wholly-owned subsidiary of Mellon Financial Corporation (“Mellon Financial”).

On July 1, 2007, the Mellon Financial and The Bank of New York Company, Inc. merged, forming The Bank of New York Mellon Corporation. As part of this transaction, Dreyfus became a wholly-owned subsidiary of The Bank of New York Mellon Corporation.

On May 22, 2007, the fund’s Board of Directors/Trustees approved the addition of Select Shares and Service Shares for Dreyfus Cash Management Plus and Dreyfus Treasury Cash Management, which became effective June 29, 2007.

During the reporting period, Dreyfus Service Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, served as the distributor of the funds’ shares, which are sold to the public without a sales charge. Effective June 30, 2007, the Distributor became known as MBSC Securities Corporation. Each fund offers the following classes of shares: Institutional Shares, Investor Shares, Administrative Shares and Participant Shares, and Dreyfus Cash Management Plus, Inc. and Dreyfus Treasury Cash Management also offer Service Shares and Select Shares. Investor, Administrative, Participant, Service and Select Shares are subject to a Service Plan adopted pursuant to Rule 12b-1 under the Act. Other differences between the classes include the services offered to and the expenses borne by each class 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.

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

Each fund’s financial statements are prepared in accordance with U.S. generally accepted accounting principles, 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: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 of the Act, which has been determined by the Board members to represent the fair value of each fund’s investments.

The Financial Accounting Standards Board (FASB) released Statement of Financial Accounting Standards No. 157 “Fair Value Measurements” (“FAS 157”). FAS 157 establishes an

authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe that the application of this standard will have a material impact on the financial statements of the fund.

(b) Securities transactions and investment income:

Securities transactions are recorded on a trade date basis. Realized gain and loss from securities transactions are recorded on the identified cost 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. Cost of investments represents amortized cost.

Dreyfus New York Municipal Cash Management 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.

Dreyfus Cash Management, Dreyfus Cash Management Plus, Inc., Dreyfus Government Cash Management and Dreyfus Treasury Cash Management may enter into repurchase agreements with financial institutions, deemed to be creditworthy by the Manager, subject to the seller’s agreement to repurchase and the fund’s agreement to resell such securities at a mutually agreed upon price. Securities purchased subject to repurchase agreements are deposited with the funds’ custodians and, pursuant to the terms of the repurchase agreement, must have an aggregate market value greater than or equal to the repurchase 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, the 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, the fund maintains the right to sell the underlying securities at market value and may claim any resulting loss against the seller.

(c) Expenses: With regards to the Company, expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to both series are allocated between them.

(d) Dividends to shareholders: It is the policy of each fund to declare dividends from investment income-net on each business day. Such dividends are paid monthly. Dividends from net realized capital gain, 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 gain can be offset by capital loss carryovers, it is the policy of each fund not to distribute such gain.

(e) Federal income taxes: It is the policy of each fund (except for Dreyfus Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax Exempt 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 Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax Exempt 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 sufficient to relieve it from substantially all federal income and excise taxes.

The FASB released FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the fund’s tax returns to determine whether the tax positions are

The Funds 73

^{NOTES TO FINANCIAL STATEMENTS (Unaudited)}(continued)

“more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management does not believe that the application of this standard will have a material impact on the financial statements of the fund.

Table 1 summarizes each fund’s unused capital loss carryover available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to January 31, 2007.

The tax character of each fund’s distributions paid to shareholders (except for Dreyfus Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax Exempt Cash Management) during the fiscal year ended January 31, 2007, were all ordinary income. The tax character of current year distributions will be determined at the end of the current fiscal year.

The tax character of distributions paid to shareholders of Dreyfus Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax Exempt Cash Management during the fiscal year ended January 31, 2007, were all tax exempt income.The tax character of current year distributions will be determined at the end of the current fiscal year.

At July 31, 2007, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statements of Investments).

INFORMATION ABOUT THE REVIEW AND APPROVAL

OF EACH FUND’S INVESTMENT MANAGEMENT AGREEMENT (Unaudited)

ALL CASH MANAGEMENT FUNDS

At a Joint Meeting of the Board of each fund held on May 22, 2007, the Board considered the re-approval for an annual period of each fund’s Management Agreement, pursuant to which the Manager provides each fund with investment advisory and administrative services. The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the funds, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent, and Quality of Services Provided to each Fund. The Board members received a presentation from representatives of the Manager regarding services provided to each fund and other funds in the Dreyfus fund complex, and discussed the nature, extent, and quality of the services provided to each fund pursuant to each fund’s Management Agreement.The Manager’s representatives noted that the funds serve institutional investors acting for themselves or in a fiduciary capacity, and reviewed the nature of the relationships that the Manager has with various intermediaries and the different needs of each.The Manager’s representatives noted the sales and servicing support provided by Dreyfus Investments Division to each fund, the diversity of distribution of the funds in the Dreyfus complex generally, and the Manager’s need for broad, deep, and diverse resources to be able to provide ongoing shareholder services in each distribution channel.The Board also reviewed the number of shareholder accounts in each fund, as well as each fund’s asset size.

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

Comparative Analysis of Each Fund’s Management Fee and Expense Ratio and Performance. The Board members reviewed reports prepared by Lipper, Inc., an independent provider of investment company data, which included information comparing each fund’s management fee and expense ratio (based on each fund’s Institutional Shares) with a group of comparable funds (the “Expense Group”) and with a broader group of funds (the “Expense Universe”) that were selected by Lipper, in each case based on the current financial statements available to Lipper as of March 31, 2007. Included in each fund’s reports were comparisons of contractual and actual management fee rates and total operating expenses.

The Board members also reviewed the reports prepared by Lipper that presented each fund’s performance (based on each fund’s Institutional Shares) for various periods ended March 31, 2007, and placed significant emphasis on comparisons of total return performance for each fund to the same group of funds as the fund’s Expense Group (the “Performance Group”) and to a group of funds that was broader than the fund’s Expense Universe (the “Performance Universe”) that also were selected by Lipper.

DREYFUS CASH MANAGEMENT

The Board reviewed the range of management fees and expense ratios of the funds in the Expense Group and Expense Universe, and noted that the fund’s contractual and actual management fees were lower and higher than the respective Expense Group medians. The Board also noted that the fund’s total expense ratio was one basis point higher than the Expense Group median and lower than the Expense Universe median.

With respect to the fund’s performance, the Board noted that the fund achieved total return results lower than the Performance Group median and higher than the Performance Universe median, for each reported time period up to 10 years. The Board noted the narrow spreads in the returns among the fund and the Performance Group funds for each reported time period.The Board noted that each Performance Group fund that had a lower actual management fee than the fund also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund trailing the Performance Group median by 3-5 basis points in the reported time periods.The Board also noted the portfolio manager’s presentation of the strategies for managing the fund’s average maturity and credit risk profile compared with those pursued by the Performance Group funds.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by mutual funds managed by the Manager or its affiliates that were reported in the same Lipper category as the fund (the “Similar Funds”), and explained the nature of the Similar Funds and the differences, from the Manager’s perspective, in providing services to the Similar Funds as compared to the fund.The Board members noted that the Similar Funds included funds used primarily as sweep vehicles for asset management accounts as well as funds with investment minimums ranging from $100,000 to $1 billion.The Board analyzed differences in fees paid to the Manager and discussed the relationship of the management fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Funds to evaluate the appropriateness and reasonableness of the fund’s management fee.

The Manager’s representatives noted that there were no similarly managed separate accounts or wrap fee accounts managed by the Manager or its affiliates with similar investment objectives, policies, and strategies as the fund.

DREYFUS CASH MANAGEMENT PLUS

With respect to the fund’s performance, the Board noted that the fund achieved total returns variously lower, higher, and at the Performance Group median, and higher than the Performance Universe median, for each reported time period up to 10 years. The Board noted the narrow spreads in the returns among the fund and the Performance Group funds for each reported time period.The Board noted that most of the Performance Group funds that had a lower actual management fee than the fund (6 of the 8) also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund trailing the Performance Group median by 1-2 basis point in certain reported time

periods. The Board also noted the portfolio manager’s presentation of the strategies for managing the fund’s average maturity and credit risk profile compared with those pursued by the Performance Group funds.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by Similar Funds, and explained the nature of the Similar Funds and the differences, from the Manager’s perspective, in providing services to the Similar Funds as compared to the fund.The Board members noted that the Similar Funds included funds used primarily as sweep vehicles for asset management accounts as well as funds with investment minimums ranging from $100,000 to $1 billion.The Board analyzed differences in fees paid to the Manager and discussed the relationship of the management fees paid in light of the services provided. The Board members considered the relevance of the fee information provided for the Similar Funds to evaluate the appropriateness and reasonableness of the fund’s management fee.

time periods.The Board noted that most of the Performance Group funds that had a lower actual management fee than the fund (8 of the 10) also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund’s median Performance Group returns. The Board also noted the portfolio manager’s presentation of the strategy for managing the fund’s average maturity compared with those pursued by the Performance Group funds.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by one Similar Fund, and explained the nature of the Similar Fund and the difference, from the Manager’s perspective, in providing services to the Similar Fund as compared to the fund.The Board noted that the Similar Fund’s management fee was the same as the fund’s management fee.The Board members considered the relevance of the fee information provided for the Similar Fund to evaluate the appropriateness and reasonableness of the fund’s management fee.

DREYFUS GOVERNMENT PRIME CASH MANAGEMENT

The Board reviewed the range of management fees and expense ratios of the funds in the Expense Group and Expense Universe, and noted that the fund’s contractual and actual management fees were lower and higher than the respective Expense Group medians. The Board also noted that the fund’s total expense ratio was a fraction of one percentage point lower than Expense Group median and lower than the Expense Universe median.

With respect to the fund’s performance, the Board noted that the fund achieved various total return results at or no more than three basis points lower than the Performance Group median, and higher than the Performance Universe median, for each reported time period up to 5 years.The Board noted the narrow spreads in the returns among the fund and the Performance Group funds for each reported time period.The Board noted that each Performance Group fund that had a lower actual management fee than the fund also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund trailing the Performance Group median by 2-3 basis points in certain reported time periods. The Board also noted the portfolio manager’s presentation of the strategy for managing the fund’s average maturity compared with those pursued by the Performance Group funds.

DREYFUS TREASURY CASH MANAGEMENT

The Board reviewed the range of management fees and expense ratios of the funds in the Expense Group and Expense Universe, and noted that the fund’s contractual and actual management fees were higher than the respective Expense Group medians.The Board also noted that the fund’s total expense ratio was a fraction of one percentage point lower than the Expense Group median and lower than the Expense Universe median.

With respect to the fund’s performance, the Board noted that the fund achieved various total return results at or no more than four basis points lower than the Performance Group median, and higher than the Performance Universe median, for each reported time period up to 10 years. The Board noted the narrow spreads in the returns among the fund and the Performance Group funds for each reported time period. The Board noted that most of the Performance Group funds that had a lower actual management fee than the fund (6 of the 9) also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund trailing the Performance Group median by 2-4 basis points in

certain reported time periods.The Board also noted the portfolio manager’s presentation of the strategy for managing the fund’s average maturity compared with those pursued by the Performance Group funds.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by Similar Funds, and explained the nature of the Similar Funds and the differences, from the Manager’s perspective, in providing services to the Similar Funds as compared to the fund.The Board members noted that the Similar Funds included funds used primarily as a sweep vehicle for asset management accounts as well as funds with investment minimums close to or the same as that of the fund.The Board analyzed differences in fees paid to the Manager and discussed the relationship of the management fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Funds to evaluate the appropriateness and reasonableness of the fund’s management fee.

With respect to the fund’s performance, the Board noted that the fund achieved total return results generally at or slightly higher than the Performance Group median, and higher than the Performance Universe median, for each reported time period up to 10 years. The Board noted the narrow spreads in the returns among the fund and the Performance Group funds for each reported time period, including that 4 basis points separated the fund from a first quintile ranking for the 1-year period.The Board noted that most of the Performance Group funds that had a lower actual management fee than the fund (7 of the 8) also had an expense reduction in effect, and the Board considered the extent to which this may account for the fund’s performance relative to the median. The Board also noted the portfolio manager’s presentation of the strategy for managing the fund’s average maturity compared with those pursued by the Performance Group funds.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by Similar Funds, and explained the nature of the Similar Funds and the differences, from the Manager’s perspective, in providing services to the Similar Funds as compared to the fund.The Board members noted that the Similar Funds included funds used primarily as a sweep vehicle for asset management accounts as well as funds with investment minimums close to or the same as that of the fund.The Board analyzed differences in fees paid to the Manager and discussed the relationship of the management fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Funds to evaluate the appropriateness and reasonableness of the fund’s management fee.

The Board reviewed the range of management fees and expense ratios of the funds in the Expense Group and Expense Universe, and noted that the fund’s contractual and actual management fees were lower than the respective Expense Group medians. The Board also noted that the fund’s total expense ratio was lower than the Expense Group and Expense Universe medians.

With respect to the fund’s performance, the Board noted that the fund achieved first quintile total return rankings among its Performance Group and Performance Universe for each reported time period up to 10 years, including number one total return rankings in the Performance Group for 3 of the 5 reported time periods.

Representatives of the Manager reviewed with the Board members the fees paid to the Manager or its affiliates by Similar Funds, and explained the nature of the Similar Funds and the differences, from the Manager’s perspective, in providing services to the Similar Funds as compared to the fund. The Board members noted that the Similar Funds included one fund used primarily as a sweep vehicle for asset management accounts as well as two other retail funds. The Board analyzed differences in fees paid to the Manager and discussed the relationship of the management fees paid in light of the services provided.The Board members considered the relevance of the fee information provided for the Similar Funds to evaluate the appropriateness and reasonableness of the fund’s management fee.

Analysis of Profitability and Economies of Scale.The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager for each fund and the method used to determine such expenses and profit.The Board considered information, previously provided and discussed, prepared by an independent consulting firm regarding the

Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund complex. The Board members also considered that the methodology had also been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of scale might emerge in connection with the management of a fund.The Board members evaluated the profitability analysis in light of the relevant circumstances for each fund, including any decline in fund assets from the prior year, 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 share-holders.The Board members also considered potential benefits to the Manager from acting as investment adviser to each fund and noted that there were no soft dollar arrangements in effect with respect to trading any fund’s portfolio.

It was noted that the Board members should consider the Manager’s profitability with respect to each fund as part of their evaluation of whether the fees under the Management Agreement bear a reasonable relationship to the mix of services provided by the Manager, including the nature, extent, and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund’s assets had been decreasing, the possibility that the Manager may have realized any economies of scale would be less. It was noted that the profitability percentage for managing each fund was within the range determined by appropriate court cases to be reasonable given the services rendered and that the profitability percentage for managing the fund was reasonable given the generally superior service levels provided. The Board also noted the Manager’s expense undertaking in effect for each fund over the past year and its effect on the profitability of the Manager.

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

The Board concluded that the nature, extent, and quality of the services provided by the Manager to each fund are ade- quate and appropriate.
As to each taxable Dreyfus Cash Management fund, the Board was satisfied with each fund’s overall performance, noting the narrow spreads in returns among each fund and its respective Performance Group, and the portfolio man- ager’s explanation of each fund’s maturity and credit risk strategy, as applicable, over the past two years.
As to each tax exempt Dreyfus Cash Management fund, the Board was satisfied with each fund’s performance.
The Board concluded that the fee paid to the Manager by each fund was reasonable in light of the services provided, comparative performance and expense and management fee information, including the expense undertakings in effect for each fund, costs of the services provided and profits to be realized and benefits derived or to be derived by the Manager from its relationship with each fund.
The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of each fund had been adequately considered by the Manager in connection with the man- agement fee rate charged to each fund, and that, to the extent in the future it were to be determined that mater- ial economies of scale had not been shared with a fund, the Board would seek to have those economies of scale shared with the fund.
The Board members considered these conclusions and determinations, along with the information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of each fund’s Management Agreement was in the best interests of the fund and its respective shareholders.
