Principal Transactions Revenue, Net [Abstract] |
PRINCIPAL TRANSACTIONS | PRINCIPAL TRANSACTIONS The table below consists of realized and unrealized gains and losses presented in Principal transactions. Activities include revenues from fixed income, equities, credit and commodities products and foreign exchange transactions that are managed on a portfolio basis and characterized below based on the primary risk managed by each trading desk (as such, the trading desks can be periodically reorganized and thus the risk categories). Principal transactions include CVA (credit valuation adjustments) and FVA (funding valuation adjustments) on over-the-counter derivatives. These adjustments are discussed further in Note 23. For transactions that are denominated in a currency other than the functional currency, including transactions denominated in the local currencies of foreign operations that use the U.S. dollar as their functional currency, the effects of changes in exchange rates are included in Principal transactions, along with the related effects of any qualifying and economic hedges. In certain transactions, Citi incurs fees and presents these fees paid to third parties in operating expenses, while others are presented net in Principal transactions. Not included in the table below is the impact of net interest income related to trading activities, which is an integral part of the profitability of trading activities (see Note 4 for information about net interest income related to trading activities).
