      Filed June 26, 2006



Dear Mr. Kaplan:

      We have reviewed your filings and have the following
comments.
Where indicated, we think you should revise your documents in
response
to these comments.  If you disagree, we will consider your
explanation
as to why our comment is inapplicable or a revision is
unnecessary.
Please be as detailed as necessary in your explanation.  In some
of
our comments, we may ask you to provide us with information so we
may
better understand your disclosure.  After reviewing this
information,
we may raise additional comments.

      Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We
look forward to working with you in these respects.  We welcome
any
questions you may have about our comments or any other aspect of
our
review.  Feel free to call us at the telephone numbers listed at
the
end of this letter.




General
1. We note your allocation of restricted stock on page 95 and your
addition of the reserved share program on page 130.  Please revise
your references, on page 1 and throughout the document, to the 14
percent of restricted stock that you are awarding employees to
disclose the following:
* after the offering, directors, executive officers and employees
will
beneficially own between 21.5 and 26.5 percent of the outstanding
shares and this percentage will increase further within the first
year
and each year thereafter as you intend to issue additional shares
to
the executive officers and other employees as part of their annual
compensation;
* you are initially awarding 6.5 percent of your outstanding stock
to
Mr. Fennebresque, who serves as your Chairman, CEO and President
and
disclose the value of the award;
* the amount and value of stock you are awarding to executive
officers
and the amount and value of stock you are awarding to senior
employees;
* clarify whether the awards of stock are subject to anti-dilution
protection;
* the amount and value of stock options you are awarding to
executive
officers and the amount and value of stock options you are
awarding to
senior employees; and
* you are reserving 5 percent of the stock being offered for
certain
directors, executive officers and employees as well as other
persons
and disclose how much of this is being offered to directors and
executive officers.

2. From the disclosures about the restricted stock awards, we are
unable to understand whether the shares have been issued but are
subject to restriction or have not been issued but will be issued
upon
vesting requirements being met. Please review the legal status of
the
restricted stock awards and revise the filing throughout to
provide
consistent disclosures about these awards, including disclosures
about
their inclusion or exclusion from common stock issued and
outstanding.

3. We note your responses to comment 1 of our letter to you dated
June
6, 2006.  Please revise your various references to Societe
Generale`s
so called "indemnification" of you for litigation expenses to
disclose
of the following information:
* you, not Societe Generale , will be indemnifying Societe
Generale
for the entire estimated costs of $79 million of all known pending
and
threatened litigation and certain known regulatory matters;
* Societe Generale will only indemnify you if the actual costs
exceed
the estimated costs of $79 million;
* Societe Generale will keep the funds to the extent that the
actual
costs are less than the estimated costs of $79 million; and
* disclose when you and Societe Generale will determine the amount
that you will pay for the estimated costs.

disclose the aggregate costs, direct and indirect, to you of the
separation, going public and related transactions and agreements
and
the effects, both immediate and prospective, on your financial
condition and results of operations.

5. As we requested in comment 4 of our letter to you dated June 6,
2006, please revise the section as follows:

to
Soc Gen;

trading
has declined each year for the past five years from approximately
$176
million in 2001 to approximately over $93 million in 2005; and
