| Re: | Comment Letter—GlaxoSmithKline plc (“GSK”) Annual Report on Form 20-F for 2009 |
Dear Mr. Rosenberg:
We appreciated the opportunity to speak with your colleague Frank Wyman yesterday in connection with the comment letter dated August 13, 2010 relating to GSK’s Annual Report on Form 20-F for 2009. As requested, this is a brief note to indicate that GSK intends to respond to the comments by September 24, 2010.
The preparation of a response to staff comment letters typically involves a number of GSK business, financial and legal personnel, as well as members of the GSK audit team from PricewaterhouseCoopers and outside counsel. Arranging for this involvement in order to meet the requested deadline would be difficult, particularly in light of the summer holiday schedules of many of the individuals involved.
Mr. Jim B. Rosenberg, p. 2
You can reach either me, or my colleagues Jerry Neugebauer and Aimée Schultz, at my number above. Please do not hesitate to contact us if you have any questions or if we can be of further assistance at this time.
Yours sincerely,
