The methodologies of the CBOE BuyWrite Indexes and the CBOE Volatility Indexes are owned by CBOE and may be covered by one or more patents or pending patent applications. CBOE's BuyWrite Indexes are designed to represent a proposed hypothetical buy-write strategy. Like many passive indexes, the BuyWrite Indexes do not take into account significant factors such as transaction costs and taxes and, because of factors such as these, many or most investors should be expected to under perform passive indexes. Investors attempting to replicate the BuyWrite Indexes should discuss with their brokers possible timing and liquidity issues. Transaction costs and taxes for buy-write strategies could be significantly higher than transaction costs for a passive strategy of buying-and-holding stocks. Past performance does not guarantee future results.
