US consumer prices, existing home sales and regional manufacturing data will be closely watched later on Thursday as investors around the globe gauge whether the world's largest economy is headed for recession.

"The deal is reasonable on 2012 consensus earnings estimates. In order to defend the bid successfully, Foster's needs to show the market its estimates are too low, thus making the multiple implied by SABMiller unreasonable," said City Index analyst Peter Esho.
