In the past, I've shown how dividend-paying stocks can fuel your retirement by providing income and growth during your golden years.

But before buying dividend-paying stocks, there's an important point that everyone must remember: Dividend payments are not guaranteed.

Sure, companies such as Johnson & Johnson (NYSE:JNJ), Coca-Cola (NYSE:KO), and Procter & Gamble (NYSE:PG) have paid dividends every year for at least the past half-century (P&G since 1890!), but even their future payments aren't guaranteed. A company's board of directors must approve every single dividend payment, even if it's already a foregone conclusion.

And there may come a time when the board will advise its company to keep the cash and reinvest in the business.

Consider the cases of Goodyear Tire & Rubber (NYSE:GT) and Eastman Kodak. Goodyear had paid a dividend every year between 1937 and 2002, but stopped in 2002 to improve company cash flow. In 2003, Kodak cut its dividend for the first time in its long history -- and by 70%, at that -- to invest in digital technology.

Hey, what about me?
While a dividend-cutting strategy can benefit a company by freeing up cash to invest in the business, for income-sensitive investors and those looking to harness the power of reinvested dividends, such an announcement can have a profound effect on financial plans.

If you find yourself in that camp, you should be looking for companies that not only have enough cash on hand to pay regular dividends, but also have room to increase them.

A good rule of thumb is to look for companies that pay out less than 80% of free cash flow and have a long track record of increasing dividend payments. That way, if the company falls on lean times, it should have some excess cash on hand to continue dividend payments.

The companies below provide an excellent example of this. Each has increased its dividend payouts by more than 10% per annum over the past five years while paying out less than 80% of free cash flow.

Reinvesting dividends in growing companies sure adds up over time. In fact, according to a study by Wharton professor Jeremy Siegel, fully 97% of the market's return from 1871 to 2003 can be attributed to reinvested dividends.

Unfortunately, the amazing power of dividends is dampened when a company cuts or reduces its payouts to shareholders. That's why it pays to look for stocks that don't stop -- financially sound companies with huge market opportunities and plenty of room to continue dividend payments.
