Where do you get the idea that GE has no tangible equity? Those revenues and earnings from the various lines of business, most of which they are #1 or #2 in, come from somewhere. Just because their financial assets dwarf their operating assets, and a standard ratio isn't defined by their intangible assets, doesn't mean that the core earnings generating power from the various businesses isn't there. They are as tangible as Berkshire's businesses. Cheers!
Well, it is more than an idea... They have about 110 Bn equity and 100 Bn intangibles/goodwill. So this means about 10 Bn tangible equity. Now if you compare this vs. the size of your balance sheet which is about 800 Bn, this is about 1% tangible equity/size of balance sheet. It would not take much to get to negative tangible equity. I don't care if they are number one or number two in their business. AIG was often referred to as the number one insurance company not so long ago...
