Pfizer Inc. raised its offer to buy AstraZeneca Plc to 69.4 billion pounds ($117 billion) in what the drugmaker described as a final bid to spur negotiations for the industry’s biggest-ever acquisition. Pfizer said it doesn’t expect AstraZeneca to accept the new cash-and-stock offer, which values the London-based company at 55 pounds a share, and is made up of 45 percent cash. On May 2, New York-based Pfizer offered 50 pounds a share, following a previous bid made in January. http://www.bloomberg.com/news/2014-05-18/pfizer-raises-offer-for-astrazeneca-to-117-billion.html
