                                      August 15, 2003

DEAR SHAREHOLDER,
Developments in the United States and abroad
encouraged a trend toward lower interest rates
that drove impressive gains in bonds during the
first six months of 2003. Stocks also ended the
reporting period higher after recovering from a
sharp sell-off early in the year. In this
volatile investment environment, money market
funds remained a comparatively safe haven for
many investors, even though their yields
declined toward record low levels.

Market conditions may remain challenging, but
regardless of the future direction of stocks
and bonds, it is important to remember that a
wise investor plans today for tomorrow's needs.
Current market activity should have little
impact on planning for your long-term
investment goals. Whether you are investing for
your retirement, your children's education, or
some other purpose, a diversified asset
allocation strategy is a disciplined approach
to investing that may help you make more
consistent progress toward your goals.

We recommend that you develop a personal asset
allocation strategy in consultation with a
financial professional who knows you, who
understands your reasons for investing, the
time you have to reach your goals, and the
amount of risk you are comfortable assuming.
Your financial professional can help you choose
the appropriate funds to implement your
strategy.

I was named president of MoneyMart Assets, Inc.
in March 2003. As always, thank you for your
continued confidence in our mutual funds. We
look forward to serving your future investment
needs.

Sincerely,

Judy A. Rice, President
MoneyMart Assets, Inc.

             Notes to Financial Statements

      MoneyMart Assets, Inc. (the 'Fund'), formerly known as the Prudential
MoneyMart Assets Fund, Inc. is registered under the Investment Company Act of
1940 as a diversified, open-end management investment company. The Fund invests
primarily in a portfolio of money market instruments maturing in thirteen months
or less whose ratings are within the two highest rating categories by a
nationally recognized statistical rating organization or, if not rated, are of
comparable quality. The ability of the issuers of the securities held by the
Fund to meet their obligations may be affected by economic developments in a
specific industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

      Securities Valuations:    Portfolio securities are valued at amortized
cost, which approximates market value. The amortized cost method involves
valuing a security at its cost on the date of purchase and thereafter assuming a
constant amortization to maturity of any discount or premium.

      Securities Transactions and Net Investment Income:    Security
transactions are recorded on the trade date. Realized gains (losses) on sales of
securities are calculated on the identified cost basis. The Fund amortizes
premiums and accretes discounts on purchases of portfolio securities as
adjustments to interest income. Interest income is recorded on the accrual
basis. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.

      Repurchase Agreements:    In connection with transactions in repurchase
agreements with U.S. financial institutions, it is the Fund's policy that its
custodian or designated subcustodians, as the case may be under triparty
repurchase agreements, take possession of the underlying collateral securities,
the value of which exceeds the principal amount of the repurchase transaction
including accrued interest. To the extent that any repurchase transaction
exceeds one business day, the value of the collateral is marked-to-market on a
daily basis to ensure the adequacy of the collateral. If the seller defaults and
the value of the collateral declines or if bankruptcy proceedings are commenced
with respect to the seller of the security, realization of the collateral by the
Fund may be delayed or limited.

      Federal Income Taxes:    It is the Fund's policy to continue to meet the
