Strange Capitol

So, now we come to really strange forms of "capitol". In return for US taxpayer money the bailed out banks are required promise to sell their stock to the government at today's (depressed) price, sometime in the future. The idea being that the taxpayers are entitled to a cut of any of the bank's future earnings in return for putting up barrels of money. The paperwork to do this is called a "warrent". We used to call them stock options in industry.
According to a Wall St Journal article, these "warrents" would be carried on the books of the bank as "capitol". Wow. First of all, the warrents aren't readily saleable, which makes them questionable as capitol. Second of all, the government owns the warrents, not the bank, so I fail to see how they contribute to the bank's capitol whatsoever, neglecting matters of proper pricing and liquidity.
Then the WSJ writer goes on to worry about how fluxuations in the value of these warrents would make the bank's capitol fluxuate.
Something does not compute here.
