Mortgage
Banking

Among the rules pending are uniform lending and
servicing standards; consumer protection measures; and
several reforms affecting loan originators

Based on the $0.12 cap proposed in December, our
interchange revenue would decline $12MM-$15MM in
2011; rules will go into effect July 21, 2011

There is still no leader of the Bureau of Consumer
Financial Protection; the Bureau will have authority over
banks greater than $10 billion in assets

BOKF will be affected by other aspects of Dodd-Frank
including new capital rules, FDIC revised assessments,
and potentially the swap push-out rules
