Last week, World Wrestling Entertainment (NYSE: WWE) reported its Q1 results. Above all, investors interested in this business look at one thing: cash flow. Why? Take a look at WWE's dividend yield.

As of Tuesday's close, the stock was yielding almost 13%! That's high. And a high dividend yield often indicates that a dividend cut may be in the offing -- the theory being that if the yield were sustainable, then buyers would rush in, and their activities would eventually lower the yield by driving the price higher.

Well, WWE hasn't had a great time of it when it comes to cash flow. I found this out when I examined the company's third quarter. Net cash from operations, unfortunately, has been overpowered at times by the dividend obligation. In fact, according to the Q4 report (pdf file), operational cash flow for 2008 dropped significantly to roughly $36 million, and the dividend obligation was over $80 million.

And that was before capital investments. That's sort of like the Undertaker throwing Mankind off the top of a steel cage. In other words, it's not pretty, folks.
