Distinguishing Features of Index Options Trading Efficiencies Index Options Are Cash-Settled — Cash Is Delivered To The Option Buyer, Not Stocks Benefits Lower Transactional Costs Tax Efficient

Disclosure This material is restricted for use only on a one-on-one basis with prospective clients. Gateway Index/RA performance shown in this illustration is an asset-weighted composite of all discretionary accounts under Gateway’s management which share the same investment objectives and hedging strategies. These results have been prepared and presented in compliance with the AIMR-PPS standards only for the period from January 1, 1993 through September 30, 2003. Prior to January 1, 1993, not all fully discretionary portfolios were represented in composites. Results shown for 1988 through 1992 are those of one representative account. The composite was created in January 1993. Gateway Index/RA performance results reflect the reinvestment of dividends and other earnings, but do not reflect the deduction of investment advisory fees. A client’s return will be reduced by the advisory fees and other expenses the account may incur. A more detailed description of Gateway’s fees is included in Form ADV, Part II. To illustrate the effect of management fees on performance, consider a $5 million account with a total return of 12% per year. Management fees are 0.85% per year on the first $5 million and 0.65% per year on assets between $5 million and $10 million, deducted monthly. At the conclusion of a five-year period, the value of the account would be $8,464,065, and management fees paid would total $264,887. Exclusive of management fees, the ending value of the account would have been $8,811,708.
