Form 20-F for the Fiscal Year Ended December 31, 2009

Dear Ms. Long:

We have received your letter of August 9, 2010, and thank you for your comments to our 2009 Annual Report on Form 20-F.  Your letter requests us to inform you as to when we will provide a response to your comments.  As discussed with Jessica Kane of the Staff, we are in the process of considering your comments and preparing our response.  However, given the difficulty in analyzing and compiling the requested Guide 7 information for a multi-national company as large as ours, we currently expect that we will be able to provide an initial response no later than September 30, 2010.  While we do not anticipate any difficulties in meeting that schedule, if for any reason we are unable to make that date, we would of course contact you in advance.

If you have any questions or require additional information, please contact Robert M. Chilstrom at (212) 735-2588 of our U.S. counsel, Skadden, Arps, Slate, Meagher & Flom LLP, or the undersigned at (212) 317-6015.

 
Very truly yours,
   
 
/s/ Jill Simeone
