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:

All of these companies have seen reasonable dividend growth in the past five years. China Petroleum & Chemical's high payout ratio looks scary, but it reflects huge reinvestments of profits back into its business that should help support growth in the future. Ventas, on the other hand, looks like its dividend growth will come to a standstill in the near future. New Alliance Bancshares may not have to halt growth entirely, but it looks like it will have to slow that growth dramatically. Still, its payout ratio is not excessive, at least over the last four quarters, leaving it some room to grow.
