(1)Under master netting agreements with our counterparties, we have the legal right of offset with a counterparty, which incorporates all of the counterparty’s outstanding

rights and obligations under the arrangement. These balances reflect additional credit risk mitigation that is available by a counterparty in the event of a counterparty’s

default, but which are not netted in our Consolidated Statements of Financial Condition because other netting provisions of U.S. GAAP are not met.

(2)Includes securities received or paid under collateral arrangements with counterparties that could be liquidated in the event of a counterparty default and thus offset

against a counterparty’s rights and obligations under the respective repurchase agreements or securities borrowing or lending arrangements.

(3)Includes $5.31 billion of securities borrowing arrangements, for which we have received securities collateral of $5.19 billion, and $645.0 million of repurchase

agreements, for which we have pledged securities collateral of $656.9 million, which are subject to master netting agreements, but we have not determined the

agreements to be legally enforceable.

(4)Includes $5.17 billion of securities borrowing arrangements, for which we have received securities collateral of $5.04 billion, and $505.0 million of repurchase

agreements, for which we have pledged securities collateral of $520.4 million, which are subject to master netting agreements, but we have not determined the

agreements to be legally enforceable.
