the biggest risk to buying bonds is that a company will go bankrupt and you will only get a percentage of what you paid (the face value). these bonds are guaranteed by their factories machines etc. so if they default, they sell the machines, factories etc and they have enough to settle with the bond holders making them very close to risk free. the problem is that banks got this deal. it wasn't made public. what was made public though is a 4 billion or so bond deal that offers the possibility of converting to Ford shares if the price goes up. Ford stock has been rising recently. The bond pays less than the US treasury rate becuase of the imbedded option to convert to ford stock. I got this quote from an article.
"The 30-year convertible bonds -- which Ford raised from $3 billion after strong demand from Wall Street -- offer several advantages over Ford's common stock. While Ford's stock dividend has been eliminated, the bonds pay a 4.25% interest rate. The bonds can be converted into shares if Ford's stock prices rise to between $9.05 and $9.20 a share; at those prices, some 500 million more shares could be added to the 1.9 billion Ford shares already on the market, diluting the value of the shares outstanding today."
"And were Ford to declare bankruptcy, the bondholders would be a step ahead of regular shareholders for a share of the company's assets. The convertible bond even includes a form of insurance for the bondholders in case Ford brings back its dividend."
