[1] A gain of $77 million, net of tax, related to net investment hedges was reclassified from other comprehensive income into income during 2012. The amount primarily related to the reversal of amounts recorded in cumulative other comprehensive income due to the incorrect application of hedge accounting on certain derivative contracts (see above for further information).
[2] Losses of $235 million, $220 million and $147 million were recognized in income related to amounts excluded from hedge effectiveness testing during 2012, 2011 and 2010, respectively.
[3] Gains (losses) on derivative contracts not designated as hedges are primarily included in Principal transactions—Trading.
[4] Gains (losses) associated with certain derivative contracts that have physically settled are excluded from the table above. Gains (losses) on these contracts are reflected with the associated cash instruments, which are also included in Principal transactions—Trading.
