BNDI seeks to generate monthly income in a tax-efficient manner by investing in a diversified portfolio of ETFs or individual bonds aimed to provide exposure to the US Aggregate Bond market. This portfolio generally consists of US Treasurys, government and corporate bonds, MBS, and ABS. These securities may have varying maturities and are primarily rated investment grade but may invest up to 30% in high-yield securities. The fund also utilizes a put-spread strategy by selling and purchasing S&P 500 Index put options, which seeks to generate additional income. There is no guarantee that the adviser will be successful. The fund may engage in active and frequent trading of portfolio securities.
