Many investors lost money over the past couple of years, but the endowments at prestigious universities suffered even worse. Investment performance at Harvard and Yale "badly trailed" the results at the average college, as The Wall Street Journal so delicately put it. I'm shocked -- but not because of these endowments' lackluster returns.

With exotic strategies and illiquid investments, Princeton registered a 24% loss in 2009, while Cornell took a 26% hit, and Harvard suffered a 27% drop. Compare those losses to the 18% drop for the median large endowment. Worse yet, many such institutions fund their operating expenses with the capital from endowments like these. If they don't generate capital gains, they may be forced to cut budgets and slash salaries.

So what?
Rather than relying on capital gains to sustain our own budgets, we need to seek additional safety in the power of ever-increasing dividend streams. With such a strategy, you'll never have to float debt in order to avoid whittling down your principal. Princeton only wishes it could say the same.

The companies below provide a dividend yield at least as high as that of the S&P 500 (about 2%), and they've grown their dividends at more than 5% per year over the last half-decade:

PepsiCo and Brown-Forman have increased their dividends quite a bit over the past five years, and their sustainable dividend growth rates suggest that they will be able to raise their dividends even more in the future. Penn Virginia, in contrast, has a much higher yield, which requires it to use a high portion of its free cash flow for dividend payouts. With its dividends exceeding its earnings, Penn Virginia's negative sustainable dividend growth rate suggests it may have to rein in its dividends soon.
