All US holdings of this investor are reported in this report. Confidential Treatment Requested (one or more holding(s) omitted). The Form 13F report requires disclosure of the manager that files the report, the name and class of the security, the CUSIP code, the number of shares as
of the end of the calendar quarter for which the report is filed, and the total market value. The market value
column should not be used as a substitute for Assets Under Management (AUM), as it does not include cash held in
accounts.
* Reported Price is the price of the security as of the portfolio date. This value is significant in that it is the last known price at which the security was still held.
An asterisk sign (*) next to the price indicates that the price is likely invalid.
