Credit Derivatives

I am seeing more and more credit derivatives. The trades originating in
Houston are coming from Jeff Kinneman's bond/debt traders but are booked in
the name of ECT Investments, Inc. or ENA. I can't be certain if these are
backed to EnronCredit.com Limited.

In particular, there is a proposed total return bond trade with DLJ
International Capital requiring ECT Investments to post collateral. We have
no master with this party. Who in Houston credit is looking at credit
derivatives?

FYI, other credit deals seem to be transacted wtih Deutsche Bank and UBS AG.
