own pipeline and maximizing the value of our in-line products, as well as through strategic and opportunistic licensing, co-promotion agreements and acquisitions. Our business- development strategy targets a number of potential growth opportunities, including biologics, vaccines, oncology, diabetes, Alzheimer’s disease, inflammation/immunology, pain, psychoses, and other products and services that seek to provide valuable healthcare solutions across developed and emerging markets. Some of our most significant business-development transactions since 2007 are described below.

• On October 15, 2009 (the acquisition date), we acquired all of the outstanding equity of Wyeth in a cash-and-stock transaction, valued, based on the closing market price of Pfizer common stock on the acquisition date, at $50.40 per share of Wyeth common stock, or a total of approximately $68 billion. We are required to divest certain animal health assets in connection with the regulatory approval process associated with our acquisition of Wyeth. As a result, in October 2009, we sold certain animal health products, research and manufacturing facilities located primarily in Fort Dodge, Iowa, as well as related assets and intellectual property, primarily from Wyeth’s Fort Dodge Animal Health portfolio in the U.S. and Canada to Boehringer Ingelheim (BI). The products primarily included cattle and small animal vaccines and some animal health pharmaceuticals. BI also acquired from us certain animal health assets in other jurisdictions, including companion animal vaccines in Australia, and cattle vaccines in Europe and South Africa, all of which are primarily manufactured at the Fort Dodge, Iowa site. In January 2010, we completed the divestiture of the legacy Fort Dodge Animal Health livestock business and certain related assets in Australia. In February 2010, we entered into an agreement for the divestiture of certain animal health assets in China, completion of which is subject to regulatory approval and other closing conditions. In the European Union, Switzerland and Mexico, in connection with the regulatory approval process associated with our acquisition of Wyeth, we are also required to divest certain other animal health assets for which we have not yet entered into definitive transaction agreements. It is possible that additional divestitures of animal health assets may be required based on ongoing regulatory reviews in other jurisdictions worldwide.

While Wyeth is now a wholly owned subsidiary of Pfizer, the merger of local Pfizer and Wyeth entities may be pending or delayed in various jurisdictions and integration in these jurisdictions is subject to completion of various local legal and regulatory obligations.
