(a)	Negative interest income for the three and six months ended June 30, 2014 and 2013, is a result of increased client-driven demand for certain securities combined with the impact of low interest rates; the offset of this matched book activity is reflected as lower net interest expense reported within short-term and other liabilities.


(b)	Largely margin loans.


(c)	Includes brokerage customer payables.


(d)	Effective January 1,2014, prior period amounts (and the corresponding amounts on the Consolidated statements of income) have been reclassified to conform with the current period presentation.
