Globally Diversified Income

Cultivating the growth of dividends for almost two decades

The Investment Income Builder Fund has been able to deliver a consistent income stream to clients while continuing to grow their principal.

We believe that the power of dividends combined with our active approach can serve two goals:

  1. Help meet short-term funding needs, such as retirement income or foundation distributions.
  2. Contribute significantly to long-term growth to help make a future income stream last.

Overview

Overview

Why Invest in This Fund?

 

  • Global, diversified multi-asset portfolio of income-producing stocks and bonds that seeks to deliver an attractive and growing income stream.
  • Proven bottom-up fundamental research process to identify dividend-paying companies with strong cash flows that have both the ability and willingness to pay and grow their dividends over time.
  • Highly active, flexible approach that allows us to go anywhere in the world to seek income.

Investment Objective

The fund’s goal is to provide investors with a level of current income which exceeds the average yield on U.S. stocks generally, and which will grow, subject to periodic fluctuations, over the years on a per share basis.

Investment Approach

The strategy is a multi-asset portfolio of global dividend-paying stocks selected via a bottom-up, fundamentals and valuation-sensitive process. The strategy seeks to generate an attractive and growing income stream, with capital appreciation over time by building a portfolio of companies that have the ability and willingness to generate cash flow and distribute dividends to its shareholders.
