Investment Objective and Policies

The Fund’s investment objective is to provide current income and gains with a secondary objective of capital appreciation. The Fund will evaluate returns on an after-tax basis, seeking to minimize and defer shareholder federal income taxes. The Fund will invest in a diversified portfolio of common stocks that seeks to exceed the total return performance of the S&P 500 index and sell S&P 500 covered call options on a continuous basis.

Performance

AVERAGE ANNUAL TOTAL RETURNS

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or market price (as applicable) with all distributions reinvested. The Fund’s performance at market market price will differ from its results at NAV. Although market price performance generally reflects investment results over time, during shorter periods, returns at market price can also be affected by factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for the Fund’s shares, or changes in Fund distributions. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Fund’s current performance may be lower or higher than quoted.

For certain periods following the ex date of distributions paid by the Fund, returns may be calculated based on the lower of the net asset value or market price of the shares on the distribution pay date rather than the true distribution reinvestment price.

There is a one-time public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange. Net asset value (NAV) is total assets less total liabilities divided by the number of shares outstanding. At the time of sale, your shares may have a market price that is above or below NAV. There is no assurance that the fund will achieve its investment objective. The fund is subject to investment risks, including possible loss of principal invested.
