Corporate earnings news and economic indicators were generally positive. However, geopolitical attention remained focused on the war on terrorism, and concerns over the impact of rising oil prices on the domestic economy were prevalent. Bond markets became tense in anticipation of rate increases by the Federal Reserve only uncertainty for bond investors was the speed and timing of the rate increases. YEAR-TO-DATE PERFORMANCE Option premiums generally remained at low levels, resulting in returns for the Gateway Fund below historical averages. Still, the Fund earned 2.83% for the first half of the year, ahead of money markets, most fixed income instruments and several equity market indexes such as the Dow Jones Industrial Average and the NASDAQ Composite Index. In fact, the S&P 500 Index, which has more than double the volatility of the Fund, earned 3.44% for the first six months of the year, only 61 basis points more than the Gateway Fund. The Lehman Brothers U. S. Intermediate Government/Credit Bond Index declined 0.11%. JANUARY RECAP The year 2004 began with the economy growing rapidly and corporate profits up handsomely. At the Federal Reserve Board meeting held on January 21, Chairman Alan Greenspan issued a subtle warning of interest rate increases. While the Board's policy toward interest rates remained unchanged, language describing a long period of low interest rates was dropped from the report. The financial markets declined on the news (or lack thereof) but recovered some poise by month-end with the S&P 500 Index delivering a total return of 1.84% for the month of January. Bonds also reacted badly to the news as sellers reversed an upward course set earlier in January. Still, the Lehman Brothers U. S. Intermediate Government/Credit Bond Index increased by 0.66%. As interest in financial markets waned, both volatility and option prices declined. The Gateway Fund delivered a total return of 0.39% for the month of January. FEBRUARY RECAP The equity market slowed its advance in February, losing a good bit of both momentum and volatility. Nevertheless, Gateway Fund returns improved over January, earning 0.69% for the month of February. Market volatility and option premiums continued at modest levels, although not at historic lows. For the month, the S&P 500 Index saw continued good news on the earnings front while investors kept a wary eye on labor markets and pronouncements by the Federal Reserve Board. The S&P 500 Index returned 1.39% for the month. Calming words on interest rate hikes caused bonds to rally. The Lehman Brothers U. S. Intermediate Government/Credit Bond Index returned 1.02% for the month. February saw both bond and equity index returns move in the direction of historic averages. The markets showed little tendency in February to break new ground, as the tone seemed more consistent with normalization. 2 GATEWAY FUND LETTER TO SHAREHOLDERS MARCH RECAP As international events (e.g., the bombing and subsequent election in Spain) collided with an apparent lack of domestic job growth in March, investors paused to interpret the new reality. February's caution turned to selling and the S&P 500 Index declined by 1.51%. The Gateway Fund produced a total return of 0.13% in March as accumulated premiums from index call options offset the decline in its stock portfolio. Bonds rallied as the stock market's decline was the bond market's good fortune. The Lehman Brothers U. S. Intermediate Government/Credit Bond Index posted a total return of 0.78% for March. Investor anxiety translated into higher volatility for stock prices and, concurrently, higher prices for options. APRIL RECAP Capital markets declined in April across the asset allocation spectrum from fixed income to equity investments. As is typical in times of market stress, Gateway Fund investors suffered significantly less. Escalation in the war on terrorism, particularly in Iraq, had an unnerving effect on investors in April. To add to their collective disquietude, expectations of rising interest rates surfaced again when Alan Greenspan, chairman of the Federal Reserve Board, testified before Congress. Such concerns overshadowed a rising tide of favorable economic and corporate earnings news, and the S&P 500 Index declined by 1.57% in April. Back on the defensive after the same type of news in March, the Gateway Fund earned premiums available from index call options, but earnings were not enough to offset the entire decline in the S&P 500 Index. The Fund declined by 0.43% in April, attesting to the benefits of hedging during a period when many investment categories lost greater value. Fears of rising interest rates and inflation sent bond investors scurrying. When the March employment number exceeded expectations, bond investors became convinced that economic growth was an irrefutable fact and, therefore, sold bonds aggressively. The Lehman Brothers U. S. Intermediate Government/Credit Bond Index declined 2.37% for the month. The April market harshness reversed much of the year-to-date gains in many asset classes, but not as dramatically in the Gateway Fund. MAY RECAP Equity markets recovered some dignity in May as investors were forced to consider both good economic data and, at the same time, disturbing reports on Iraq and rising oil prices. The Gateway Fund earned a total return of 0.86% in May, about equal to the net option premiums available for most of the month. On balance, investors overcame the impact of disappointments in Iraq and responded favorably to a surfeit of excellent first quarter corporate earnings reports. This reaction drove the S&P 500 Index to a gain of 1.37% for the month, with little reflection of the dichotomy between the blue-chip and growth-oriented ends of the market. Bond investors continued to show concern regarding the Federal Reserve Board's previously announced plans to raise interest rates in the face of early evidence of inflationary pressures. Most of the damage occurred in the first half of the month, as rates spiked sharply before easing toward month-end. Nevertheless, the Lehman Brothers U. S. Intermediate Government/Credit Bond Index edged down 0.45% in May, furthering the rather significant loss registered in April. 3 GATEWAY FUND LETTER TO SHAREHOLDERS JUNE RECAP In the month of June, the S&P 500 Index oscillated. Alternating up and down with light volume, it attempted to handicap the impact of a pending interest rate hike by the Federal Reserve Board, uncertainty over oil prices and the handover of power in Iraq. In the end, investors decided to focus on positive corporate earnings reports and other signs of continued economic recovery, which extended the May rally for the S&P 500 Index, but still finished below its February high. For the month of June, the S&P 500 Index earned 1.94%. The Gateway Fund maintained a steady advance and finished the month of June up 1.15%, its best month in the first half of 2004. The bond market rallied when the Federal Reserve Board announced its 25 basis points interest rate hike on June 30, saving a positive monthly return. The Lehman Brothers U.S. Intermediate Government/Credit Bond Index finished up 0.30%, its only positive month of the second quarter. MARKET PERSPECTIVE All in all, while the first six months of 2004 offered little reward to investors in the broad market indexes, Gateway Fund investors could take some solace in earning a positive return while negotiating a great deal of market uncertainty. As we look to the second half of the year, downside risks are still present and, because of these, we expect volatility to be on increase. Whether or not that increased volatility will be accompanied by a declining market is certainly a concern, but a foregone conclusion. The Gateway Fund should be able to earn worthwhile premiums regardless of which market emerges while maintaining an effective hedge against a significant market decline over a short period of time. We cordially invite you to visit our website at www.gatewayfund.com for updates on the Fund's investment results and statistics. As always, we appreciate your support and continued confidence. /s/ Walter G. Sall Walter G.

SIGNIFICANT ACCOUNTING POLICIES The Gateway Trust (the Trust) is an Ohio business trust, registered under the Investment Company Act of 1940, which is authorized to establish and operate one or more separate series of mutual funds. The Trust currently operates one diversified mutual fund, the Gateway Fund (the Fund). The investment objective of the Fund is to capture the majority of the higher returns associated with equity market investments, while exposing investors to significantly less risk than other equity investments. The Fund attempts to achieve its investment objective primarily by owning the 500 common stocks included in the S&P 500 Index and by selling index call options on its indexed portfolio. The Fund also buys index put options that can protect the Fund from a significant market decline over a short period of time. The following is a summary of the Fund's significant accounting policies: INVESTMENTS VALUATION - The Fund values its portfolio securities as of the close of the regular session of trading on the New York Stock Exchange (normally 4:00 P.M., Eastern time). Securities, other than option contracts, traded on a national stock exchange are valued at the last reported sales price on the primary exchange on which the security is traded. Securities traded in the over-the-counter market, and which are quoted by NASDAQ, are valued at the NASDAQ Official Closing Price. Option contracts (both purchased and written) are valued at the average of the closing bid and asked quotations. Securities for which market quotations are not readily available and securities in which trading has been suspended during the day are valued at fair value as determined in good faith under procedures adopted by the Board of Trustees. SHARE VALUATION - The net asset value per share of the Fund is calculated daily by dividing the total value of the Fund's assets, less liabilities, by the number of shares outstanding. The offering price and redemption price per share are equal to the net asset value per share. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME - Investment transactions are recorded on the trade date. Capital gains and losses are calculated on an identified cost basis. Dividend income is recorded on the ex-dividend date and interest income is accrued daily. OPTION TRANSACTIONS - The Fund purchases index put options and writes (sells) index call options. When the Fund writes an index call option, an amount equal to the net premium received (the premium less commission) is recorded as a liability and is subsequently valued until the option expires or the Fund enters into a closing purchase transaction. When an index call option expires on its stipulated expiration date or the Fund enters into a closing purchase transaction, the difference between the net premium received and any amount paid at expiration or on effecting a closing purchase transaction, including commission, is treated as a realized gain or, if the net premium received is less than the amount paid, as a realized loss. The Fund, as writer of an index call option, bears the risk of an unfavorable change in the market value of the index underlying the written option. DISTRIBUTIONS TO SHAREHOLDERS - Distributions from net investment income and net realized capital gains, if any, are recorded on the ex-dividend date and are declared and paid to shareholders annually. REPURCHASE AGREEMENTS - The Fund requires the custodian to hold sufficient collateral to secure repurchase agreements. To reduce the chance of loss in its repurchase transactions, the Fund enters into repurchase agreements only with banks that have more than $1 billion in assets and are creditworthy in the judgment of Gateway Investment Advisers, L.P. (the Adviser). 23 GATEWAY FUND NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) FEDERAL INCOME TAXES - The Fund intends to comply with the provisions of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and distribute substantially all of its taxable income to shareholders. Based on this policy, the Fund makes no provision for income taxes. At December 31, 2003, the components of distributable earnings on a tax basis were as follows (000's): Cost of portfolio investments $ 1,093,340 ================= Gross unrealized appreciation $ 311,427 Gross unrealized depreciation 48,107 ----------------- Net unrealized appreciation 263,320 Undistributed ordinary income 70 Capital loss carryforwards (186,689) Other loss deferrals (5,708) ----------------- Distributable earnings $ 70,993 ================= At December 31, 2003, $2,865,000 of the Fund's capital loss carryforwards expires December 31, 2009 and $183,824,000 expires December 31, 2011. The difference between the book basis and tax basis of distributable earnings resulted from the tax deferral of losses on wash sales and certain hedged transactions, and the tax recognition of net unrealized depreciation on open option contracts at December 31, 2003. There were no differences between the book basis and tax basis of distributions paid for the years ended December 31, 2003 and 2002. At June 30, 2004, based on a $1,371,105,000 federal tax cost of common stocks and options, gross unrealized appreciation totaled $359,167,000, gross unrealized depreciation totaled $66,480,000 and net unrealized appreciation totaled $292,687,000. ESTIMATES - The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. 2. TRANSACTIONS WITH AFFILIATES The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 that allows for the payment of distribution expenses related to the sale and distribution of its shares. In any year, distribution expenses cannot exceed 0.50% of the Fund's average daily net assets. The Fund also pays the Adviser an investment advisory and management fee under the terms of a Management Agreement at an annual rate of 0.925% of the Fund's average daily net assets minus all distribution expenses incurred by the Fund. The Adviser receives no separate fee for its transfer agency, fund accounting and other services to the Fund, and the Adviser pays the Fund's expenses of reporting to shareholders under the Management Agreement. If total annual operating expenses (excluding taxes, interest, brokerage commissions and expenses of an extraordinary nature) exceed 1.50% of the Fund's average daily net assets, the Adviser has agreed to reduce its fee as necessary to limit the Fund's expenses to this level. 24 GATEWAY FUND NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2004 (UNAUDITED) 3. INVESTMENT TRANSACTIONS For the six months ended June 30, 2004, cost of purchases of investment securities (excluding short-term investments) totaled $244,191,000 and proceeds from sales totaled $27,849,000. The Fund may write (sell) call options on stock indexes in exchange for cash (that is, "the option premium") to enhance earnings on the portfolio securities. However, using these contracts limits the opportunity to participate in appreciation of the underlying portfolio beyond certain upper limits set by the contracts. The Fund may also buy put options on stock indexes. The purchase of put options involves the risk of loss of all or part of the cash paid for the put options. In general, the liability recorded upon receipt of written option premiums increases to offset rises and decreases to offset declines in portfolio value. Similarly, the value of purchased put options generally increases to offset declines and decreases to offset rises in portfolio value. For the six months ended June 30, 2004, transactions in written options were as follows: Contracts Premiums (000's) --------- ---------------- Outstanding at December 31, 2003 12,982 $ 45,734 Options written 50,800 133,592 Options terminated in closing purchase transactions (46,563) (133,260) Options expired (2,316) (7,979) ------ ------------- Outstanding at June 30, 2004 14,903 $ 38,087 ====== ============= 4. BANK LINE OF CREDIT The Fund has an uncommitted $55 million bank line of credit to be used as a temporary liquidity source for meeting redemption requests. Borrowings under this arrangement, expiring October 31, 2004, bear interest at the bank's prime rate minus 0.50%. There are no fees associated with maintaining this facility. During the six months ended June 30, 2004, there were no borrowings on this line of credit. 25 WEB SITE For general information regarding the Gateway Fund, visit us at www.gatewayfund.com AFFORDABILITY $1,000 Minimum Initial Investment $500 Minimum Initial IRA Investment $100 Minimum Additional Investment No Annual Account Charges No-Fee IRA Account CONVENIENCE Automatic Investment Program Systematic Withdrawal Program Telephone Redemptions FLEXIBILITY Available for numerous investment options: Individuals IRAs Trusts Pension Plans Gifts to Minors ITEM 1.
