In the nine-month period ended September 30, 2015, the presentation of certain assets was changed from C&IS to Treasury and Other to reflect better the internal management responsibility for these assets. In addition to the transfer of assets, the Corporation’s internal funds pricing treatment of deposits that fund the transferred assets was updated to reflect the economics of these deposits.
