Have You Heard of 10%-Yielding

I've uncovered a small group of double-digit yielders that are so unusual nobody knows quite what to call them.

I've heard them called perpetual cash machines (PCM), income deposit securities (IDS), enhanced income securities (EIS), and income participating securities (IPS). I just call them "stapled products."

Call them what you want. You can buy them through just about any brokerage... but you need to find them first. Only a handful -- less than ten -- exist in the entire world.

What makes these securities so unique is that they provide two separate sources of income stapled together. Typically, companies pair a high-yield bond with their common stock. In that case, the distribution comprises one part bond interest income and one part common stock dividend. That gives you predictable bond payouts with potential equity appreciation.

And that income is pretty hefty. The stapled securities I've found pay an average yield of 7-8%. The top one currently yields about 10%. That's good in any environment, much less a nearly 0% interest rate economy.

So what's behind the companies that issue these unique high-yield securities?

In order for a firm to issue a stapled product, it must generate a steady stream of regular annual cash flows. After all, they are expected to pay both regular interest on a bond and steady dividends. As a result, those companies with unpredictable earnings and poor cash flows need not apply. Since cash flows must be stable, only steady companies in solid, non-volatile industries consider issuing shares.

The ones I've found come from a telecom in Alabama, a bus-maker from Canada, and a hospital-owner with facilities in South Dakota and Oklahoma.

Now, I wouldn't call stapled products risk-free -- certainly, there's no free lunch -- but these securities have demonstrated above-average performance.

Over the past three years, for example, my perpetual cash machines have delivered average total returns of 14% annually, trouncing the S&P 500's 1% average annual returns over the same period.

Past success is of course no guarantee of future performance, and some of these securities are more volatile than others so you have to be selective.

But as a group, I count them as one of my favorite asset classes for the money they have made my loyal High-Yield Investing readers over the years and for the steady monthly or quarterly income they provide.
