Yahoo assesses the situation and comes to the following conclusions:

Most of these firms have limited cash for a rainy day, and a lot of debt, with large interest payments due over the next year. In ordinary times, it might not be so hard to refinance loans, or get new ones, to help keep the cash flowing. But in an acute credit crunch it's a different story, and at companies where sales are down and going lower, skittish lenders may refuse to grant any more credit. It's a terrible time to be cash-poor.

That's why Moody's assigns most of these firms its lowest rating for short-term liquidity. And all the firms on this list have long-term debt that Moody's rates Caa or lower, which means the borrower is considered at least a "very high" credit risk.

Once a company defaults on its debt, or fails to make a payment, the next step is usually a Chapter 11 bankruptcy filing. Some firms continue to operate while in Chapter 11, retaining many of their employees. Those firms often shed debt, restructure, and emerge from bankruptcy as healthier companies.

But it takes fresh financing to do that, and with money scarce, more bankrupt firms than usual are likely to liquidate - like Circuit City. That's why corporate failures are likely to be a major drag on the economy in 2009: In a liquidation, the entire workforce often gets axed, with little or no severance. That will only add to unemployment, which could hit 9 or even 10 percent by the end of the year.

As for those companies at least tangentially related to MMA, we have this:

Station Casinos. (Privately owned, about 14,000 employees). Las Vegas has already been creamed by a biblical real-estate bust, and now it may face the loss of its home-grown gambling joints, too. Station - which runs 15 casinos off the strip that cater to locals - recently failed to make a key interest payment, which is often one of the last steps before a Chapter 11 filing. For once, the house seems likely to lose.

Have no fear UFC diehards. Trump is getting a comeuppance as well:

Trump Entertainment Resorts Holdings. (TRMP; about 9,500 employees; stock down 94%). The casino company made famous by The Donald has received several extensions on interest payments, while it tries to sell at least one of its Atlantic City properties and pay down a stack of debt. But with casino buyers scarce, competition circling, and gamblers nursing their losses from the recession, Trump Entertainment may face long odds of skirting bankruptcy.

The common link here is obviously the gambling and casino business, whatever that is worth. Other notable companies on the list: Rite Aid, Blockbuster, Sirius Satellite Radio, Chrysler, Six Flags and Sbarro. Hold onto your asses folks. This one's going to get nasty.
