The fund invests in government and corporate US bond ETFs of various investment quality or maturity. It employs a covered call option strategy that could potentially mitigate volatility, generate capital and additional yield from interest income, distributions, and call option premiums. The portfolio is rebalanced quarterly. The ETF has a mutual fund counterpart, which shares the same portfolio advisor and investment objectives, that invests all or substantially all of its assets in the fund. As an actively managed fund, the portfolio manager has discretion to make any investment decision at any time.
