A LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this semiannual report for General Government Securities Money Market Fund, covering the six-month period from December 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 early in the reporting period when long-term interest rates fell amid robust demand from global investors, but returns later moderated amid heightened market volatility stemming from renewed domestic economic concerns and expectations of higher short-term interest rates over the months ahead.Yet, yields of money market instruments remained steady, 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 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 December 1, 2014, through May 31, 2015, as provided by Bernard W. Kiernan, Jr., Senior Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended May 31, 2015, General Government Securities Money Market Fund’s Class A shares produced an annualized yield of 0.00%, and its Class B shares produced an annualized yield of 0.00%. Taking into account the effects of compounding, the fund’s Class A and Class B shares produced annualized effective yields of 0.00% and 0.00%, respectively.¹

Amid continued evidence of a persistent-but-choppy economic recovery, yields of short-term U.S. government securities remained anchored near zero percent when the Federal Reserve Board (the “Fed”) left its target for the federal funds rate unchanged in a range between 0% and 0.25%.

The Fund’s Investment Approach

The fund seeks as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. To pursue its goal, the fund invests in securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities, and repurchase agreements (including tri-party repurchase agreements).The securities in which the fund invests include those backed by the full faith and credit of the U.S. government and those that are neither insured nor guaranteed by the U.S. government.

U.S. Economic Recovery Back on Track after Soft Patch

The reporting period began in the midst of a sustained domestic economic recovery, but GDP growth decelerated to a 2.2% annualized rate during the fourth quarter of 2014 after posting more robust growth earlier in the year. Yet, economic news remained positive in December 2014, with the unemployment rate slipping to 5.6% and the creation of 329,000 jobs. January 2015 saw not just the addition of another 201,000 jobs, but compensation for hourly workers jumped by its largest margin

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

since the recession.A slight increase in the unemployment rate to 5.7% was attributed to more workers entering the labor force.The unemployment rate dipped to 5.5% in February, and 266,000 jobs were created, mainly in the food services, professional and business services, construction, health care, transportation, and warehousing industries.Wages and personal incomes also moved higher during the month, while energy prices began to rebound from previously depressed levels. On a more negative note, exports and orders for durable goods weakened in February, and retail sales proved disappointing.

March brought less encouraging economic news when job creation moderated to 119,000 positions even as the unemployment rate was unchanged. Moreover, an appreciating U.S. dollar drove the U.S. trade deficit to a six-and-a-half year high. In contrast, average hourly wages rose 0.3% during the month, helping to push the personal savings rate to its highest level in more than two years. For the first quarter overall, the U.S. economy contracted modestly, posting an annualized GDP growth rate of –0.7%.

The economy seemed to rebound in April.The unemployment rate slid to 5.4% and 221,000 new jobs were created, lending credence to the Fed’s comments that the forces behind the winter soft patch were transitory.Average hourly earnings continued to advance modestly during the month, and the manufacturing and service sectors continued to expand.The housing market also showed renewed signs of life in April when housing starts surged about 9% above year-ago levels and permit issuance for new construction climbed about 6% on a year-over-year basis. In contrast, industrial production dropped for the fifth consecutive month, which some analysts attributed to seasonal factors and the impact of lower commodity prices on mining output.

The rebound continued in May, as employers added an estimated 280,000 jobs, new unemployment claims remained well below year-ago levels, and hourly wages in the private sector rose 0.3%.The unemployment rate ticked higher to 5.5% as previously discouraged workers resumed their job searches. Meanwhile, stabilizing currency exchange rates enabled the U.S. trade deficit to shrink significantly during the month, and retail sales posted robust gains.

Rates May Begin Rising Gradually Later This Year

At its June meeting, the Fed 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 Committee views as normal in the longer run.”Therefore, while many analysts expect the first in a series of rate hikes later this year, those increases are likely to be gradual.

In light of these expectations — and until it becomes clearer that higher short-term rates are imminent — we currently intend to maintain the fund’s weighted average maturity in a range we consider to be in line with industry averages. As always, we remain focused on U.S. government securities with good liquidity characteristics.

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.

1 Annualized effective yield is based upon dividends declared daily and reinvested monthly. Past performance is no

guarantee of future results.Yields fluctuate.Yields provided for the fund’s Class A and Class B shares reflect the

absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect that may be

extended, terminated, or modified at any time. Had these expenses not been absorbed, fund yields would have

been lower.

UNDERSTANDING YOUR FUND’S EXPENSES (Unaudited)

As a mutual fund investor, you pay ongoing expenses, such as management fees and other expenses. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds.You also may pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial adviser.

Review your fund’s expenses

The table below shows the expenses you would have paid on a $1,000 investment in General Government Securities Money Market Fund from December 1, 2014 to May 31, 2015. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.

COMPARING YOUR FUND’S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

	Class A	Class B
Expenses paid per $1,000^†	$.56	$.56
Ending value (after expenses)	$ 1,024.38	$ 1,024.38

† Expenses are equal to the fund’s annualized expense ratio of .11% for Class A and .11% for Class B, multiplied
by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

NOTE 1—Significant Accounting Policies:

General Government Securities Money Market Fund (the “fund”) is a separate diversified series of General Government Securities Money Market Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company, currently offering two series, including the fund.The fund’s investment objective is to seek as high a level of current income 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 NewYork 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 to the public without a sales charge.The fund is authorized to issue 11 billion shares of $.001 par value Common Stock.The fund currently offers two classes of shares: Class A (5 billion shares authorized) and Class B (6 billion shares authorized). Class A and Class B shares are identical except for the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Class A shares are subject to a Service Plan adopted pursuant to Rule 12b-1 under the Act, Class B shares are subject to a Distribution Plan adopted pursuant to Rule 12b-1 under the Act and Class A and Class B shares are subject to a Shareholder Services Plan. In addition, Class B shares are charged directly for sub-accounting services provided by Service Agents (securities dealers, financial institutions or other industry professionals) at an annual rate of .05% of the value of the average daily net assets of Class B shares. During the period ended May 31, 2015, sub-accounting service fees amounted to $272,247 for Class B shares and are included in Shareholder servicing costs in the Statement of Operations. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Fund 15

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 Company accounts separately for the assets, liabilities and operations of each series. Expenses directly attributable to each series are charged to that series’ operations; expenses which are applicable to all series are allocated among them on a pro rata basis.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The Company enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(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 Company’s Board of Directors (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 trans-

action between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value.This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For example, money market securities are valued using amortized cost, 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 Fund 17

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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	1,181,045,723
Level 3—Significant Unobservable Inputs	—
Total	1,181,045,723

† 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 may enter into repurchase agreements with financial institutions, deemed to be creditworthy by Dreyfus, subject to the seller’s agreement to repurchase and the 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 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 its right to sell the underlying securities at market value and may claim any resulting loss against the seller.The 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 to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, if such qualification is in the best interests of its shareholders, by complying with the applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended 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.

Each tax year in the three-year period ended November 30, 2014 remains subject to examination by the Internal Revenue Service and state taxing authorities.

The tax character of distributions paid to shareholders during the fiscal year ended November 30, 2014 was all ordinary income.The tax character of current year distributions will be determined at the end of the current fiscal year.

At May 31, 2015, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

The Fund 19

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 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 1¹/₂% of the value of the fund’s average daily net assets, the fund may deduct from payments 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 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 $5,131,316 during the period ended May 31, 2015.

(b) Under the Service Plan with respect to Class A, adopted pursuant to Rule 12b-1 under the Act, Class A shares bear directly the costs of preparing, printing and distributing prospectuses and statements of additional information and of implementing and operating the Service Plan, such aggregate amount not to exceed in any fiscal year of the fund, the greater of $100,000 or .005% of the average daily net assets of Class A. In addition, Class A shares pay the Distributor for distributing its shares, servicing shareholder accounts (“Servicing”) and advertising and marketing relating to Class A shares at an annual rate of .20% of the value of the average daily net assets of Class A. The Distributor may pay one or more Service Agents a fee with respect to Class A shares owned by shareholders with whom the Service Agent has a Servicing relationship or for whom the Service Agent is the dealer or holder of record. The schedule of such fees and the basis upon which such fees will be paid shall be determined from time to

time by the Distributor. If a holder of Class A shares ceases to be a client of a Service Agent, but continues to hold Class A shares, the Distributor will be permitted to act as a Service Agent with respect to such fund shareholders and receive payments under the Service Plan for Servicing.The fees payable for Servicing are payable without regard to actual expenses incurred. During the period ended May 31, 2015, Class A shares were charged $39,313 pursuant to the Service Plan.

Under the Distribution Plan with respect to Class B, adopted pursuant to Rule 12b-1 under the Act, Class B shares bear directly the costs of preparing, printing and distributing prospectuses and statements of additional information and of implementing and operating the Distribution Plan, such aggregate amount not to exceed in any fiscal year of the fund the greater of $100,000 or .005% of the average daily net assets of Class B. In addition, Class B shares reimburse the Distributor for payments made to third parties for distributing its shares at an annual rate not to exceed .20% of the value of its average daily net assets. During the period ended May 31, 2015, Class B shares were charged $1,114,835 pursuant to the Distribution Plan.

Under the Shareholder Services Plan with respect to Class B (the “Class B Shareholder Services Plan”), Class B shares pay the Distributor at an annual rate of .25% of the value of the average daily

The Fund 21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

net assets of its shares for servicing shareholder accounts.The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. The Distributor may make payments to Service Agents with respect to these services. The Distributor determines the amounts to be paid to Service Agents.

Dreyfus had undertaken, from December 1, 2014 through May 31, 2015, to reduce the expenses of Class B shares, if the aggregate expenses of Class B shares (excluding taxes, brokerage commissions and extraordinary expenses) exceeded an annual rate of 1.03% of the value of the average daily net assets of Class B shares. Such expense limitations are voluntary, temporary and may be terminated at any time. During the period ended May 31, 2015, Class B shares were charged $1,361,223 pursuant to the Class B Shareholder Services Plan, of which $12,235 was reimbursed by Dreyfus.

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 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 $15,139 for transfer agency services and $726 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 $35.

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 $37,184 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 $564 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 $6,140 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 $480,770, Distribution Plan fees $192,334, Shareholder Services Plan fees $279,951, custodian fees $25,566, Chief Compliance Officer fees $2,113 and transfer agency fees $7,642, which are offset against an expense reimbursement currently in effect in the amount of $874,695.

(d) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 3—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.

A LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this semiannual report for General Treasury Prime Money Market Fund, covering the six-month period from December 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 early in the reporting period when long-term interest rates fell amid robust demand from global investors, but returns later moderated amid heightened market volatility stemming from renewed domestic economic concerns and expectations of higher short-term interest rates over the months ahead. Yet, yields of money market instruments remained steady, 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.

Thank you for your continued confidence and support.

J. Charles Cardona
President
The Dreyfus Corporation
June 15, 2015

DISCUSSION OF FUND PERFORMANCE

For the period of December 1, 2014, through May 31, 2015, as provided by Bernard W. Kiernan, Jr., Senior Portfolio Manager

Fund and Market Performance Overview

For the six-month period ended May 31, 2015, General Treasury Prime Money Market Fund’s Class A shares produced an annualized yield of 0.00%, and its Class B shares produced an annualized yield of 0.00%.Taking into account the effects of compounding, the fund’s Class A and Class B shares produced annualized effective yields of 0.00% and 0.00%, respectively.¹

Amid continued evidence of a persistent-but-choppy economic recovery, yields of short-term U.S. Treasury obligations remained anchored near zero percent as the Federal Reserve Board (the “Fed”) left its target for the federal funds rate unchanged in a range between 0% and 0.25%.

The Fund’s Investment Approach

The fund seeks as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. To pursue its goal, the fund normally invests substantially all of its assets in U.S.Treasury securities.

U.S. Economic Recovery Got Back on Track in Spring

The Fund 3

DISCUSSION OF FUND PERFORMANCE (continued)

February, and 266,000 jobs were created, mainly in the food services, professional and business services, construction, health care, transportation, and warehousing industries. Wages and personal incomes also moved higher during the month, while energy prices began to rebound from previously depressed levels. On a more negative note, exports and orders for durable goods weakened in February, and retail sales proved disappointing.

The economy seemed to get back on track in April. The unemployment rate slid to 5.4% and 221,000 new jobs were created, lending credence to the Fed’s comments that the forces behind the winter soft patch were transitory. Average hourly earnings continued to advance modestly during the month, and the manufacturing and service sectors continued to expand.The housing market also showed renewed signs of life in April when housing starts surged about 9% above year-ago levels and permit issuance for new construction climbed about 6% on a year-over-year basis. In contrast, industrial production dropped for the fifth consecutive month, which some analysts attributed to seasonal factors and the impact of lower commodity prices on mining output.

Rates May Begin Rising Gradually Later This Year

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.

1 Annualized effective yield is based upon dividends declared daily and reinvested monthly. Past performance is no

guarantee of future results.Yields fluctuate.Yields provided for the fund’s Class A and Class B shares reflect the

absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking in effect that may be

extended, terminated, or modified at any time. Had these expenses not been absorbed, fund yields would have

been lower.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

General Treasury Prime Money Market Fund (the “fund”) is a separate diversified series of General Government Securities Money Market Funds, Inc. (the “Company”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and operates as a series company, currently offering two series, including the fund. The fund’s investment objective is to seek as high a level of current income 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 to the public without a sales charge.The fund is authorized to issue 9 billion shares of $.001 par value Common Stock.The fund currently offers two classes of shares: Class A (1 billion shares authorized) and Class B (8 billion shares authorized). Class A and Class B shares are identical except for the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Class A shares are subject to a Service Plan adopted pursuant to Rule 12b-1 under the Act. Class B shares are subject to a Distribution Plan adopted pursuant to Rule 12b-1 under the Act and Class A and Class B shares are subject to a Shareholder Services Plan. In addition, Class B shares are charged directly for sub-accounting services provided by Service Agents (securities dealers, financial institutions or other industry professionals) at an annual rate of .05% of the value of the average daily net assets of Class B shares. During the period ended May 31, 2015, sub-accounting service fees amounted to $613,924 for Class B shares and are included in Shareholder servicing costs in the Statement of Operations. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The 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 trans-

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements.These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The 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	2,311,269,985
Level 3—Significant Unobservable Inputs	—
Total	2,311,269,985

† 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.

(c) Dividends to shareholders: It is the policy of the fund to declare dividends daily from investment income-net. Such dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”).To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains.

The Fund 17

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

visions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

Each tax year in the three-year period ended November 30, 2014 remains subject to examination by the Internal Revenue Service and state taxing authorities.

Under the Regulated Investment Company Modernization Act of 2010, the 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.

The fund has an unused capital loss carryover available for federal income tax purposes to be applied against future net realized capital gains, if any, realized subsequent to November 30, 2014.The fund has $3,555 of short-term capital losses which can be carried forward for an unlimited period.

At May 31, 2015, the cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes (see the Statement of Investments).

NOTE 2—Management Fee and Other Transactions with Affiliates:

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 1¹/₂% of the value of the fund’s average daily net assets, the fund may deduct from payments to be made to Dreyfus, or Dreyfus will bear, such excess expense. During the period ended May 31, 2015, there was no expense reimbursement pursuant to the Agreement.

(b) Under the Service Plan with respect to Class A, adopted pursuant to Rule 12b-1 under the Act, Class A shares bear directly the costs of preparing, printing and distributing prospectuses and statements of additional information and implementing and operating the Service Plan, such aggregate amount not to exceed in any fiscal year of the fund, the greater of $100,000 or .005% of the average daily net assets of Class A. In addition, Class A shares pay the Distributor for distributing their shares, servicing shareholder accounts (“Servicing”) and advertising and marketing relating to Class A shares at an annual rate of .20% of the value of the average daily net assets of Class A. The Distributor may pay one or more Service Agents a fee with respect to Class A shares owned by shareholders with whom the Service Agent has a Servicing relationship or for whom the Service Agent is the dealer or holder of record. The schedule of such fees and the basis upon which such fees will be paid shall be determined from time to time by the Distributor. If a holder of Class A shares ceases to be a client of a Service Agent, but continues to hold Class A shares, the Distributor will be permitted to act as a Service Agent with respect to such fund shareholders and receive payments under the Service Plan for Servicing.The fees payable for Servicing are payable without regard

to actual expenses incurred. During the period ended May 31, 2015, Class A shares were charged $24,323 pursuant to the Service Plan.

(c) Under the Shareholder Services Plan with respect to Class A (the “Class A Shareholder Services Plan”), Class A shares reimburse the Distributor at an amount not to exceed an annual rate of .25% of the value of the average daily net assets of its shares 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. Dreyfus had undertaken from December 1, 2014 through May 31, 2015, to reduce the expenses of Class A shares, if the aggregate expenses of Class A shares (excluding taxes, brokerage fees and extraordinary expenses) exceeded an annual rate of .80% of the value of the average daily net assets of Class A shares. Such expense limitations are voluntary, temporary and may be terminated at any time. During the period ended May 31, 2015, Class A shares were charged $2,145 pursuant to the Class A Shareholder Services Plan.

Under the Shareholder Services Plan with respect to Class B (the “Class B Shareholder Services Plan”), Class B shares pay the Distributor at an

annual rate of .25% of the value of the average daily net assets of its shares for the provision of certain services. The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. The Distributor may make payments to Service Agents with respect to these services. The Distributor determines the amounts to be paid to Service Agents.

Dreyfus had undertaken, from December 1, 2014 through May 31, 2015, to reduce the expenses of Class B shares, if the aggregate expenses of Class B shares (excluding taxes, brokerage commissions and extraordinary expenses) exceeded an annual rate of 1.03% of the value of the average daily net assets of Class B shares. Such expense limitations are voluntary, temporary and may be terminated at any time. During the period ended May 31, 2015, Class B shares were charged $3,069,623 pursuant to the Class B Shareholder Services Plan.

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 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 $17,513 for transfer agency services and $766 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 $36.

The Fund 21

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

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 $57,431 pursuant to the custody agreement. These fees were partially offset by earnings credits of $79.

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 $598 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 $6,140 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 $1,019,751, Distribution Plan fees $407,906, Shareholder Services Plan fees $607,126, custodian fees $37,167, Chief Compliance Officer fees $2,113 and transfer agency fees $7,277, which are offset against an expense reimbursement currently in effect in the amount of $2,004,196.

(d) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 3—Regulatory Developments:

NOTE 4—Plan of Reorganization:

On May 5, 2015, the Board approved an Agreement and Plan of Reorganization (the “Reorganization”) between General Government Securities Money Market Funds, Inc., on behalf of the fund, and Dreyfus 100% U.S. Treasury Money Market Fund (the “Acquired Fund”).The Reorganization is subject to the approval of the shareholders of the Acquired Fund. The Reorganization is anticipated to occur on or about December 4, 2015. The Reorganization provides for the Acquired Fund to transfer all of its assets, subject to its liabilities, to the fund, in exchange for a number of Dreyfus Class shares of the fund of equal value to the assets less liabilities of the Acquired Fund.The fund’s Dreyfus Class shares will then be distributed to the Acquired Fund’s shareholders on a pro rata basis in liquidation of the Acquired Fund.
