Form 20-F and other submissions to the US Securities and Exchange Commission

We file periodic reports and submit other information about UBS to the US Securities and Exchange Commission (SEC). ­Principal among these filings is Form 20-F; our Annual Report filed pursuant to the US Securities Exchange Act of 1934.

Our Form 20-F filing is structured as a "wrap-around" document. Most sections of the filing are provided by referring to parts of the Handbook 2006 / 2007 or to parts of the Financial Report 2006. However, there is a small amount of additional information in Form 20-F which is not presented elsewhere, and is particularly targeted at readers in the US. You are encouraged to refer to this additional disclosure.

You may read and copy any document that we file with the SEC on the SEC's website, www.sec.gov, or at the SEC's public reference room at 450 Fifth Street NW, Washington, DC, 20549. Please call the SEC by dialing +1-800-SEC-0330 (in the US) or +1 202 942 8088 (outside the US) for further information on the operation of its public reference room. You may also inspect our SEC reports and other information at the New York Stock Exchange, Inc., 20 Broad Street, New York, NY 10005.
