Translation of Non-United States Currencies

currencies other than US dollars are translated at period end exchange rates. The resulting adjustments are charged or
credited directly to the
Equity section of the Consolidated Balance Sheet
. Revenue and expenses are translated at the
weighted-average exchange rates for the period. Realized and unrealized transaction gains and losses are included in
income in the period in which they occur. Transaction losses of $37 million, $25 million and $27 million, net of hedging
activities, were recognized in 2012, 2011 and 2010, respectively.
