Middleton: Wells Will Need At Least $22B

``The bank's TCE ratio stands at 3.06% which is significantly lower than the prescribed limit of 4.0%. Further, based on our projections, the bank's TCE will likely fall to 2.37% at the end of 2010 after adjusting for losses (both accounting as well as economic losses on account of its significant off-balance sheet exposure towards the QSPE's and SIV's) worth US$64 billion.
