LORD ABBETT U.S. GOVERNMENT & GOVERNMENT SPONSORED ENTERPRISES MONEY MARKET FUND
SEMIANNUAL REPORT
FOR THE SIX-MONTH PERIOD ENDED DECEMBER 31, 2005
DEAR SHAREHOLDERS: We are pleased to provide you with this overview of the Lord
Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund's
strategies and performance for the six-month period ended December 31, 2005. On
this and the following pages, we discuss the major factors that influenced
performance.
Thank you for investing in Lord Abbett mutual funds. We value the trust
that you place in us and look forward to serving your investment needs in the
years to come.
BEST REGARDS,
/s/ Robert S. Dow
ROBERT S. DOW
CHAIRMAN
- --------------------------------------------------------------------------------
Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE REPORTING PERIOD?
A: The Federal Reserve Board (the Fed) raised the federal funds rate four times
in the first six months of the fund's fiscal year, ending calendar 2005 at 4.25
percent, amid concerns about inflationary pressures. (The fed funds rate is the
interest rate charged by banks with excess reserves at a Federal Reserve Board
district bank to other banks needing overnight loans to meet reserve
requirements.)
Short-term rates rose, while longer rates remained remarkably stable over
much of the period as inflation metrics trended downward. However, 10-year
maturities slipped lower in late December 2005, creating an inverted yield
curve.
Q: HOW DID THE FUND PERFORM OVER THE SIX-MONTH PERIOD ENDED DECEMBER 31, 2005?
A: The fund (Class A shares) finished the six-month period ended December 31,
2005, with total net assets of $290.8 million and a seven-day current yield of
3.3 percent. The current yield refers to the income generated by an investment
in the fund over a seven-day period, which is then annualized. The yield
quotation more closely reflects the current earnings of the fund than the
one-year total return quotation. For the six-month period ended December 31,
2005, the fund returned 1.5 percent, reflecting performance at the net asset
value (NAV) of Class A shares with all distributions reinvested, compared with
its peer group, the Lipper U.S. Government Money Market Funds Average,(1) which
returned 1.5 percent in the same period. STANDARDIZED AVERAGE ANNUAL RETURNS,
WHICH INCLUDE THE REINVESTMENT OF ALL DISTRIBUTIONS, AS OF DECEMBER 31, 2005,
ARE 1 YEAR: 2.48 PERCENT, 5 YEARS: 1.44 PERCENT, AND 10 YEARS: 3.10 PERCENT.
During certain periods shown, expense reimbursements were in place. Without such
expense reimbursements, the fund's returns would have been lower. Class A shares
purchased with a front-end sales charge have no contingent deferred sales charge
(CDSC). However, certain purchases of Class A shares made without a front-end
sales charge may be subject to a CDSC. Please

AN INVESTMENT IN MONEY MARKET FUNDS IS NEITHER INSURED NOR GUARANTEED BY
THE FEDERAL DEPOSIT INSURANCE CORPORATION 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. PERFORMANCE DATA
QUOTED REFLECT PAST PERFORMANCE AND ARE NO GUARANTEE OF FUTURE RESULTS. CURRENT
PERFORMANCE MAY BE HIGHER OR LOWER THAN THE PERFORMANCE QUOTED. THE INVESTMENT
RETURN AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT
SHARES, ON ANY GIVEN DAY OR WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR
ORIGINAL COST. YOU CAN OBTAIN PERFORMANCE DATA CURRENT TO THE MOST RECENT
MONTH-END BY CALLING LORD ABBETT AT 800-821-5129 OR REFERRING TO OUR WEBSITE AT
www.LordAbbett.com.
Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE?
A: In general, fund yield kept pace with short-term interest rates. Consistent
with its goal of providing current income with minimum credit risk, the fund
remained invested in high-quality, short-term securities issued by the U.S.
Treasury and certain U.S. government agency securities.
THE FUND'S PORTFOLIO IS ACTIVELY MANAGED AND, THEREFORE, ITS HOLDINGS AND
WEIGHTINGS OF A PARTICULAR ISSUER OR PARTICULAR SECTOR AS A PERCENTAGE OF
PORTFOLIO ASSETS ARE SUBJECT TO CHANGE.

EXPENSE EXAMPLE
As a shareholder of the fund you incur ongoing costs, including management
fees; distribution and service (12b-1) fees (currently only Class B shares have
an active 12b-1 Plan); and other Fund expenses. This Example is intended to help
you understand your ongoing costs (in dollars) of investing in the fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
The Example is based on an investment of $1,000 invested at the beginning
of the period and held for the entire period (July 1, 2005 through December 31,
2005).
ACTUAL EXPENSES
For each class of the fund, the first line of the applicable table on the
following pages provides information about actual account values and actual
expenses. You may use the information in this line, together with the amount you
invested, to estimate the expenses that you paid over the period. Simply divide
your account value by $1,000 (for example, an $8,600 account value divided by
$1,000 = 8.6), then multiply the result by the number in the first line under
the heading entitled "Expenses Paid During the Period 7/1/05 - 12/31/05" to
estimate the expenses you paid on your account during this period.
HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
For each class of the fund, the second line of the applicable table on the
following pages provides information about hypothetical account values and
hypothetical expenses based on the fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period. You may
use this information to compare the ongoing costs of investing in the fund and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

- --------------------------------------------------------------------------------
Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and do not reflect any transactional costs, such as
sales charges. Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
1. ORGANIZATION
Lord Abbett U.S. Government & Government Sponsored Enterprises Money Market
Fund, Inc. (the "Fund"), is registered under the Investment Company Act of 1940
(the "Act") as a diversified, open-end management investment company. The Fund
was incorporated under Maryland law on May 9, 1979.
The investment objective of the Fund is to seek high current income and
preservation of capital through investments in high quality, short-term, liquid
securities.
The Fund offers four classes of shares: Classes A, B, C and Y. There are no
front end sales charges on shares of each class, although there may be a
contingent deferred sales charge ("CDSC") applied to each class of shares as
follows: Class A shares acquired through an exchange and redeemed within 24
months (12 months if shares were purchased on or after November 1, 2004)
following certain purchase made without a sales charge; Class B shares redeemed
before the sixth anniversary of purchase; and Class C shares redeemed before the
first anniversary of purchase.
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
certain estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates.
2. SIGNIFICANT ACCOUNTING POLICIES
(a) INVESTMENT VALUATION-The Fund values securities utilizing the amortized cost
method, which approximates market value. Under this method, all investments
purchased at a discount or premium are valued by amortizing the difference
between the original purchase price and maturity value of the issue over the
period to maturity. Securities purchased at face value are valued at cost,
which approximates market value.
(b) SECURITY TRANSACTIONS-Security transactions are recorded as of the date that
the securities are purchased or sold (trade date). Realized gains and losses
on sales of portfolio securities are calculated using the identified-cost
method.
(c) INVESTMENT INCOME-Interest income is recorded on the accrual basis.
Investment income is allocated to each class of shares based upon the
relative proportion of net assets at the beginning of the day.
(d) FEDERAL TAXES-It is the policy of the Fund to meet the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all taxable net income to its
shareholders. Therefore, no federal income tax provision is required.
(e) EXPENSES-Expenses, excluding class specific expenses, are generally
allocated to each class of shares based upon the relative proportion of net
assets at the beginning of the day. Class B shares bear all expenses and
fees related to the Class B 12b-1 distribution plan.
14
<Page>
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)
(f) REPURCHASE AGREEMENTS-The Fund may enter into repurchase agreements with
respect to securities. A repurchase agreement is a transaction in which the
Fund acquires a security and simultaneously commits to resell that security
to the seller (a bank or securities dealer) at an agreed-upon price on an
agreed-upon date. The Fund requires at all times that the repurchase
agreement be collateralized by cash or by securities of the U.S. Government,
its agencies, its instrumentalities, or U.S. Government sponsored
enterprises having a value equal to, or in excess of, the value of the
repurchase agreement (including accrued interest). If the seller of the
agreement defaults on its obligation to repurchase the underlying securities
at a time when the value of those securities has declined, the Fund may
incur a loss upon disposition of the securities.
3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES
MANAGEMENT FEE
The Fund has a management agreement with Lord, Abbett & Co. LLC ("Lord Abbett")
pursuant to which Lord Abbett supplies the Fund with investment management
services and executive and other personnel, pays the remuneration of officers,
provides office space and pays for ordinary and necessary office and clerical
expenses relating to research and statistical work and supervision of the Fund's
investment portfolio. The management fee is based on average daily net assets at
the following annual rates:
<Table>
First $250 million .50%
Next $250 million .45%
Over $500 million .40%
</Table>
For the fiscal year ending June 30, 2006, Lord Abbett contractually agreed to
reimburse the Fund to the extent necessary so that each class' net annual
operating expenses do not exceed the following annual rates:
<Table>
<Caption>
CLASS % OF AVERAGE DAILY NET ASSETS
- ------------------------------------------
A .70%
B 1.45%
C .70%
Y .70%
</Table>
Lord Abbett provides certain administrative services to the Fund pursuant to an
Administrative Services Agreement at an annual rate of .04% of the Fund's
average daily net assets.
12b-1 DISTRIBUTION PLANS
The Fund has adopted a distribution plan with respect to one or more classes of
shares pursuant to Rule 12b-1 of the Act, which provides for the payment of
ongoing distribution and service fees to Lord Abbett Distributor LLC (the
"Distributor"), an affiliate of Lord Abbett. The fees are accrued daily at
annual rates based upon average daily net assets as follows:
<Table>
<Caption>
FEE CLASS A(1) CLASS B CLASS C(1)
- ------------------------------------------------------------------------------------
Service and distribution fee .15% .75% .25%
</Table>
(1) The Fund has not activated its Class A and Class C Plans, and therefore, no
payments are currently authorized under the Plans.
15
<Page>
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)
Class Y does not have a distribution plan.
One Director and certain of the Fund's officers have an interest in Lord Abbett.
4. DISTRIBUTIONS
Dividends from net investment income are declared daily and paid monthly.
5. DIRECTORS' REMUNERATION
The Fund's officers and the one Director who are associated with Lord Abbett do
not receive any compensation from the Fund for serving in such capacities.
Outside Directors' fees are allocated among all Lord Abbett-sponsored funds
based on the net assets of each fund. There is an equity based plan available to
all outside Directors under which outside Directors must defer receipt of a
portion of, and may elect to defer receipt of an additional portion of
Directors' fees. The deferred amounts are treated as though equivalent dollar
amounts have been invested proportionately in the funds. Such amounts and
earnings accrued thereon are included in Directors' Fees on the Statement of
Operations and in Directors' Fees Payable on the Statement of Assets and
Liabilities and are not deductible for U.S. Federal income tax purposes until
such amounts are paid.
6. EXPENSE REDUCTIONS
The Fund has entered into arrangements with its transfer agent and custodian
whereby credits realized as a result of uninvested cash balances are used to
reduce a portion of the Fund's expenses.
7. CUSTODIAN AND ACCOUNTING AGENT
State Street Bank & Trust Company ("SSB") is the Fund's custodian and accounting
agent. SSB performs custodial, accounting and recordkeeping functions relating
to portfolio transactions and calculating the Fund's NAV.
8. INVESTMENT RISKS
The Fund's yield may vary in response to changes in interest rates and other
market factors.
The Fund generally invests a substantial portion of its assets in money market
securities issued by various government sponsored enterprises such as Federal
Home Loan Mortgage Corporation and Federal National Mortgage Association. Such
securities are not guaranteed by the U.S. Government, but are supported only by
the credit of the particular government sponsored enterprises involved, and the
discretionary authority of the U.S. Treasury to purchase the enterprise
obligations. There is no assurance that the U.S. Government will provide
financial support to such enterprises.
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.
Although the Fund seeks to preserve the value of an investment at $1.00 per
share, it is possible to lose money by investing in the Fund.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONCLUDED)
These factors can affect the Fund's performance.

APPROVAL OF ADVISORY CONTRACTS
At meetings on December 7 and 8, 2005, the Board, including all Directors who
are not interested persons, considered whether to approve the continuation of
the existing management agreement between the Fund and Lord Abbett. In addition
to the materials the Board had reviewed throughout the course of the year, the
Board received materials relating to the management agreement before the meeting
and had the opportunity to ask questions and request further information in
connection with its consideration. The Board also took into account its
familiarity with Lord Abbett gained through its previous meetings and
discussions, and the examination of the portfolio management team conducted by
members of the Contract Committee during the year.
The materials received by the Board included, but were not limited to, (1)
information provided by Lipper Analytical Services, Inc. regarding the
investment performance of the Fund compared to the investment performance of a
group of funds with substantially similar investment objectives (the
"performance universe") and to the investment performance of an appropriate
securities index (if such an index existed), for various time periods each
ending September 30, 2005, (2) information on the effective management fee rates
and expense ratios for funds with similar objectives and similar size (the "peer
group"), (3) sales and redemption information for the Fund, (4) information
regarding Lord Abbett's financial condition, (5) an analysis of the relative
profitability of the management agreement to Lord Abbett, (6) information
regarding the distribution arrangements of the Fund, (7) information regarding
the personnel and other resources devoted by Lord Abbett to managing the Fund.
INVESTMENT MANAGEMENT SERVICES GENERALLY. The Board considered the investment
management services provided by Lord Abbett to the Fund, including investment
research, portfolio management, and trading, and Lord Abbett's commitment to
compliance with all relevant legal requirements. The Board also observed that
Lord Abbett was solely engaged in the investment management business and
accordingly did not experience the conflicts of interest resulting from being
engaged in other lines of business. The Board noted that Lord Abbett did not use
brokerage commissions to purchase third-party research. The Board also
considered the investment advisory services provided by Lord Abbett to other
clients, the fees charged for the services, and the differences in the nature of
the services provided to the Fund and other Lord Abbett Funds, on the one hand,
and the services provided to other clients, on the other.
INVESTMENT PERFORMANCE AND COMPLIANCE. The Board reviewed the Fund's investment
performance as well as the performance of the performance universe of funds,
both in terms of total return and in terms of other statistical measures. The
Board observed that the Fund's performance of the Class A shares of the Fund was
in the third quintile of its performance universe in the nine-month period, in
the fourth quintile for the one- and three-year periods, and in the fifth
quintile for the five- and ten-year periods. The Board also observed that the
performance was below that of the Lipper U.S. Government Money Market Index for
each period.
LORD ABBETT'S PERSONNEL AND METHODS. The Board considered the qualifications of
the personnel providing investment management services to the Fund, in light of
its investment objective and discipline. Among other things, they considered the
size, experience, and turnover rates of Lord Abbett's investment management
staff, Lord Abbett's investment methodology and philosophy, and Lord Abbett's
approach to recruiting, training, and retaining investment management personnel.
The Board determined that Lord Abbett had the expertise and resources to manage
the Fund effectively.
18
<Page>
NATURE AND QUALITY OF OTHER SERVICES. The Board considered the nature, quality,
costs, and extent of administrative and other services performed by Lord Abbett
and Lord Abbett Distributor and the nature and extent of Lord Abbett supervision
of third party service providers, including the Fund's transfer agent and
custodian.
EXPENSES. The Board considered the expense ratio of the Fund and the expense
ratios of peer groups. It also considered the amount and nature of the fees paid
by shareholders. The Board observed that Lord Abbett had implemented a total
expense cap for the Fund that limited the total expense ratios of Classes A, C,
and Y to not more than 0.70% and the total expense ratio of Class B to not more
than 1.45%. The Board also observed that the total expense ratio of Classes A
and C were approximately one basis point below the median of the peer group, the
total expense ratio of Class B was approximately sixty-six basis points above
the median of the peer group, and the total expense ratio of Class Y was
approximately twenty-five basis points above the median of the peer group. The
Board observed, in addition, that the Fund had relatively high transfer agent
and shareholder servicing costs compared to many of its peers due to its
relatively small average account size.
PROFITABILITY. The Board considered the level of Lord Abbett's profits in
managing the Fund, including a review of Lord Abbett's methodology for
allocating its costs to its management of the Fund. The Board concluded that the
allocation methodology had a reasonable basis and was appropriate. It considered
the profits realized by Lord Abbett in connection with the operation of the Fund
and whether the amount of profit was fair for the management of the Fund. The
Board also considered the profits realized from other businesses of Lord Abbett,
which may benefit from or be related to the Fund's business. The Board
considered Lord Abbett's profit margins in comparison with available industry
data, both accounting for and ignoring marketing and distribution expenses, and
how those profit margins could affect Lord Abbett's ability to recruit and
retain investment personnel. The Board recognized that Lord Abbett's
profitability was a factor in enabling it to attract and retain qualified
investment management personnel to provide services to the Fund. The Board noted
that Lord Abbett's profitability had increased, in part due to an increase in
assets under management, but concluded that Lord Abbett's profitability overall
and with respect to the Fund was not excessive.
ECONOMIES OF SCALE. The Board considered whether there had been any economies of
scale in managing the Fund, whether the Fund had appropriately benefited from
any such economies of scale, and whether there was potential for realization of
any further economies of scale. The Board concluded that the existing advisory
fee schedule adequately addressed any economies of scale in managing the Fund.
OTHER BENEFITS TO LORD ABBETT. The Board considered the character and amount of
fees paid by the Fund and the Fund's shareholders to Lord Abbett and Lord Abbett
Distributor for services other than investment advisory services. The Board also
considered the revenues and profitability of Lord Abbett's investment advisory
business apart from its mutual fund business, and the intangible benefits
enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board
observed that Lord Abbett Distributor receives 12b-1 fees from the Funds as to
shares held in accounts for which there is no other broker of record, may retain
a portion of the 12b-1 fees from the Funds, and receives a portion of the sales
charges on sales and redemptions of some classes of shares. In addition, Lord
Abbett accrues certain benefits for its business of providing investment advice
to clients other than the Funds, but that that business also benefits the Funds.
The Board also noted that Lord Abbett, as disclosed in the prospectus of each
Fund, has entered into revenue sharing arrangements with certain entities that
distribute shares of the Funds.
19
<Page>
ALTERNATIVE ARRANGEMENTS. The Board considered whether, instead of approving
continuation of the management agreement, employing one or more alternative
arrangements might be in the best interests of the Fund, such as continuing to
employ Lord Abbett, but on different terms.
In considering whether to approve the continuation of the management agreement,
the Board did not identify any single factor as paramount or controlling. This
summary does not discuss in detail all matters considered. After considering all
of the relevant factors, the Board unanimously found that continuation of the
existing management agreement was in the best interests of the Fund and its
shareholders and voted unanimously to approve the continuation of the management
agreement.
