  measured against a daily VWAP⁴ benchmark (1.4 basis points

sweep program balances with participating banks. These deposits are not
reported in the Company’s statement of financial condition.

Note 2: In connection with our currency diversification strategy,
we have determined to base our net worth in GLOBALs, a basket of 14
major currencies in which we hold our equity. The total effect of the
currency diversification strategy is reported in Comprehensive Income;
the components are reported in (1) Other Income in the corporate segment
and (2) Other Comprehensive Income (“OCI”) on the balance sheet. The
effect of the GLOBAL on our comprehensive income can be estimated by
multiplying the total equity for the period by the change in the U.S.
dollar value of the GLOBAL during the same period.

Note 3: Trade money is the total amount of money clients spent or
received, including all commissions and fees.

Note 4: Consistent with the clients’ trading activity, the
computed VWAP benchmark includes extended trading hours.
