The fund is actively managed to generate income by writing put options on US large-cap equities. The fund examines available option premiums in order to write short-dated, out-of-the-money put options, while investing the portfolio in cash and cash equivalents. To select put options, volatility, fundamental and technical factors, price sensitivity, and sector diversification are considered. The put options written by the ETF may either be exchange-traded or over-the-counter. Note that the fund may be subject to a loss if the stock prices decline significantly over the option period.
