[1] Includes over-the-counter derivative instruments in a net asset value position which may require the counterparty to pledge collateral to the Company. As of September 30, 2012 and December 31, 2011, $320 and $1.4 billion, respectively, of cash collateral liability was netted against the derivative asset value in the Condensed Consolidated Balance Sheet and is excluded from the table above. See footnote 3 below for derivative liabilities.

[2] Approximately $6.0 billion and $4.0 billion of investment sales receivable that are not subject to fair value accounting are excluded as of September 30, 2012 and December 31, 2011, respectively.

[3] Represents embedded derivatives associated with non-funding agreement-backed consumer equity linked notes.

[4] Includes over-the-counter derivative instruments in a net negative market value position (derivative liability). In the Level 3 roll-forward table included below in this Note 4, the derivative asset and liability are referred to as “freestanding derivatives” and are presented on a net basis.
