The fund seeks to deliver attractive monthly income by holding an equal-weighted portfolio of large-cap North American energy companies with a covered call option writing program. Since the fund is actively managed, the fund adviser has full discretion to make adjustments to the portfolio, which is rebalanced at least semi-annually. The fund also utilizes a covered call strategy, which allows the fund to mitigate downside risk and generate income. It generally writes at or slightly out-of-the-money call options with a term of less than two months on up to 100% of the portfolio value. Call options sold by the fund may either be exchange-traded or over-the-counter. Although it provides hedging protection and generates premiums, the use of a covered call strategy may cap the fund's potential gains. Additionally, the fund may hold cash equivalents or money market instruments to meet its obligations.
