The Investment Income Builder Fund employs a mix of equities and bonds. The equity component is a diversified portfolio consisting of both foreign and domestic companies with histories of paying dividends and showing the capacity to increase them. It is typically weighted towards sectors with traditionally high payout ratios, such as utilities, financials, and REITs. The bond component earns income and mitigates the volatility of returns from the equity component. The asset mix normally focuses on the corporate sector and may include exposure to convertibles, preferred stocks, and high-yield instruments.
