   1.                                                   Please tell us in more
detail how you use Economic Income (Loss), Economic Operating

   2.                                                   It appears that many of
the adjustments you make to GAAP revenue when calculating
                                                        Economic Income revenue
are to reclassify amounts from other income statement line

         items to revenue. For example, income (loss) from proprietary trading
has been
         reclassified from other income to revenue. Additionally, gross
interest expense for net
         securities borrowed and securities loaned activities has been
reclassified to revenue.
         Please explain to us why you believe it is appropriate to characterize
these amounts and
         any similar    other adjustments    as revenue for non-GAAP purposes
when they not
         recognized as revenue under GAAP.
3.       We note the adjustments to a) recognize incentive fees during periods
when the fees are
         not yet crystalized b) recognize startup costs of a fund over the
expected life of a fund and
         c) recognize retainer fees related to investment banking activities
earned during the period
         that would otherwise be deferred until closing. Please tell us how you
considered the
         guidance in the Division   s Non-GAAP C&DI 100.04 when determining the
         appropriateness of your presentation. Specifically, explain to us how
you considered
         whether your non-GAAP measure includes individually tailored revenue
recognition and
         measurement methods that could violate Rule 100(b) of Regulation G.

to disclose the
         underlying causes for material changes in these line items from

investment strategies,
         industries or issuers to which the net gains (losses) on securities,
derivatives and other
         investments relate. Similarly, for your Consolidated Funds, consider
disclosure identifying
         any specific funds performance contributing to net realized and
