The fund employs a covered call option writing strategy while holding a portfolio of US Treasurys. The fund primarily invests in shorter-term US Treasury securities. It may also invest in longer-term US Treasury bonds through passively managed ETFs. To mitigate downside risk and generate income, the fund actively manages a covered call strategy that is expected to write at- or near-the-money call options on up to 100% of the longer-term US Treasurys portfolio value. The fund may also write cash-covered put options at the adviser's discretion. The strategy aims to generate attractive option premiums that increase cash flow for distribution and reinvestment, downside protection, and lower overall volatility of returns. The adviser reviews the portfolio on an ongoing basis and has full discretion to make buy, sell, and hold decisions at any time, including increasing or decreasing the percentage of options written.
