“The fund’s goals are to provide interesting current income, and over the long term, to grow that income on a per-share basis. If we’re able to find companies that show both an ability and willingness to pay shareholders a
significant portion of earnings, and those companies are in a position to create value over time through growth, we may find continued success.”

— Brian McMahon

WE GO WHERE THE INCOME IS

Global Diversification Can Improve Yield
U.S. corporations have historically reinvested capital in businesses rather than returning it to shareholders in the form of dividends. But in overseas markets with stronger dividend-paying cultures, this tendency is reversed.

BEYOND UTILITIES

Investors sometimes think of high dividend yields as limited to the utilities or telecom sectors, but we search for promising dividend payers in a range of sectors and geographies.

A SUPPORTING ROLE: BONDS OF ANY TYPE

Fixed income plays a supporting role in the portfolio, aiding in income production and potentially muting volatility over time. And in the Income Builder portfolio, we don’t limit ourselves to bonds of a particular type or credit quality in the search for the best risk/reward trade-off. Bonds have ranged from under 10% today to more than 40% of fund assets.

BEYOND CURRENT YIELD

Investors tend to focus on current yield, or current income divided by current price. While useful, current yield is only a snapshot. It can be helpful to look beyond it—to yield on cost, which is annual income divided by the cost of an initial investment—reflecting an investor’s yield on their original purchase.

If one were to invest a hypothetical $100,000 in a security with a current yield of 5% at purchase, and income grew by 50% over time, the yield on cost of the initial investment would have grown from 5% to 7.5%.

THE IMPORTANCE OF PER-SHARE CASH FLOW

With both declining price and declining income, an investor can experience a current yield that remains level. Similarly, with a rising price and flat income, current yield would decline. So as investors choose which vehicles to use for income, it’s important that they understand per-share cash flow (the actual dollar amount of income received per share) as a true measure of income—along with current yield and yield on cost.
