The new accounting standard requiring banks to bring assets back on balance sheet had a negligible impact on Wells Fargo. Despite having over $2.0 trillion of off-balance sheet assets, Wells consolidated just $10 billion of risk-weighted assets when the new standard took effect January 1. (See slide 17 in the bank's supplemental earnings release)
The idea behind the new accounting standard is to bring hidden assets back into the light of day so that regulators can insure proper levels of capital are held against them. With Wells, this appears not to be happening.
Last summer, the bank estimated the new standard would raise risk-weighted assets by $46 billion.* In its last quarterly filing, it revised the estimate down to $25 billion.** When the standard finally went into effect, the figure was just $10 billion.
Total off balance sheet assets, meanwhile, were over $2.0 trillion at the end of September. (see page 31)
One reason for the giant difference is that "conforming" mortgages comprise a bit over half of Wells' off balance sheet assets. These are eligible for a government guarantee via Fannie Mae, Freddie Mac, or Ginnie Mae, argues the bank, so it needn't consolidate them since they pose no risk to its balance sheet.
