Prudential’s Gibraltar Fund, Inc. Semiannual Report         June 30, 2003

LETTER TO PLANHOLDERS

n DEAR PLANHOLDER A more optimistic tone characterized the financial markets in the second quarter of 2003. In fact, it was the best quarter in 4 ¹/2 years for both the U.S. stock market and markets outside the United States, even as the long-standing bond market rally persisted. The market rallies were very welcome after the long bear market. In general, investors should expect both good and bad markets within any extended time span. Good financial planning takes this into account by diversifying your portfolio with an asset allocation that is appropriate to your stage in life and your tolerance for the possibility of loss. A financial professional can help you create a complete picture of the potential demands on your resources. Moreover, financial professionals are familiar with the long-term returns and historical volatility of various asset classes. Together, you and your financial professional can plan an investment program that takes into account your reasons for investing, the time you have to reach your goals, and the amount of risk you feel comfortable assuming. On behalf of Prudential Financial, I would like to thank you for your confidence in our products. We look forward to continuing to serve your investment needs. Sincerely, David R. Odenath, Jr. President, Prudential’s Gibraltar Fund, Inc. July 31, 2003 PRESIDENT DAVID R. ODENATH, JR.

NOTES TO THE FINANCIAL STATEMENTS OF

PRUDENTIAL’S GIBRALTAR FUND, INC.

(Unaudited)

General

Prudential’s Gibraltar Fund, Inc. (the “Fund”) was originally incorporated in the State of Delaware on March 14, 1968 and was reincorporated in the State of Maryland effective May 1, 1997. It is registered as an open-end, diversified management investment company under the Investment Company Act of 1940, as amended. The investment objective of the fund is growth of capital to the extent compatible with a concern for preservation of principal by investing in common stocks and other securities convertible into common stock. The Fund was organized by The Prudential Insurance Company of America (“PICA”) to serve as the investment medium for the variable contract accounts of The Prudential Financial Security Program (“FSP”). The Fund does not sell its shares to the public. The accounts will redeem shares of the Fund to the extent necessary to provide benefits under the contracts or for such other purposes as may be consistent with the contracts.

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 Valuation:    Securities listed on a securities exchange are valued at the last sale price on such exchange on the day of valuation or, if there was no sale on such day, at the mean between the last reported bid and ask prices, or at the last bid price on such day in the absence of an asked price. Securities traded via Nasdaq are valued at the official closing price provided by Nasdaq. Securities that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed by Prudential Investments LLC (“PI” or “Manager”), in consultation with Jennison Associates LLC (“Jennison” or “Subadviser”), to be over-the-counter, are valued by an independent pricing agent or principal market maker.

Short-term securities which mature in more than 60 days are valued at current market quotations and those short-term securities which mature in 60 days or less are valued at amortized cost, which approximates market value.

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. 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.

Securities Transactions and Net Investment Income:    Securities transactions are recorded on the trade date. Realized gains (losses) on sales of securities are calculated on the identified cost basis. Dividend income is recorded on the ex-dividend date and 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.

Custody Fee Credits:    The Fund has an arrangement with its custodian bank, whereby uninvested monies earn credits which reduce the fees charged by the custodian. Such custody fee credits are presented as a reduction of gross expenses in the accompanying statement of operations.

Dividends and Distributions:    Dividends from net investment income are declared and paid semi-annually. The Fund will distribute at least annually net capital gains in excess of capital loss carryforwards, if any. Dividends and distributions are recorded on the ex-dividend date. Dividends from net investment income and net realized capital gains of the Fund will normally be declared and reinvested in additional full and fractional shares. Some dividends may be paid in cash.

Income distributions and capital gain distributions are determined in accordance with income tax regulations which may differ from generally accepted accounting principles.

Taxes:    It is the Fund’s policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net income and capital gains, if any, to shareholders. Therefore, no federal income tax provision is required.

C1

Withholding taxes on foreign dividends have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates.

Note 2: Management Fee and Other Transactions with Affiliates

Management Fee:    The Fund has a management agreement with Prudential Investments LLC (“PI”). Pursuant to this agreement, PI has responsibility for all investment advisory services and supervises the subadviser’s performance of such services. PI has entered into a subadvisory agreement with Jennison Associates LLC (“Jennison”). The subadvisory agreement provides that Jennison will furnish investment advisory services in connection with the management of the Fund. PI pays for the services of Jennison, compensation of officers of the Fund, costs related to shareholder reporting, occupancy and certain clerical and administrative expenses of the Fund. The Fund bears all other costs and expenses.

The management fee paid to PI is computed daily and payable monthly, at an annual rate of 0.55 of 1% of the Fund’s average daily net assets.

PI, PICA and Jennison are indirect, wholly-owned subsidiaries of Prudential Financial, Inc.

The United States federal income tax basis of the Fund’s investments and the net unrealized appreciation as of June 30, 2003 were as follows:

Tax Basis of Investments	Appreciation	Depreciation	Net Unrealized Appreciation
$205,315,818	$14,139,339	$(8,733,102)	$5,406,237

The difference between book basis and tax basis is attributable to deferred losses on wash sales.
