Under typical market environments, the fund's strategy is to direct substantially all, and no less than 80%, of its total capital (including assets acquired through borrowing) into bonds and other debt instruments. The portfolio mainly comprises debt obligations that carry high investment-grade ratings—specifically, within the top four tiers (AAA, AA, A, or BAA, or comparable grades) from at least one nationally recognized rating agency. Unrated securities are included only if deemed of similar caliber by First National Fund Advisers, the sub-adviser for the fund.
