costs in North America and Europe. Kraft has had to contend with the higher cost of ingredients such as corn, sugar and cocoa. Kraft chief executive Irene Rosenfeld said, “We expect it will remain weak for the foreseeable future.” Taking into account integration costs, the acquisition knocked about 33% off Kraft's earnings per share immediately after the purchase of Cadbury. In March 2011, Kraft caused national outrage when they sold the site of a historic Cadbury factory it vowed not to close for £50million after initially publicly promising the continuity of production within the UK in order to win over support for the deal from shareholders.

Proposed split After a period of poor share performance and investor criticism, Rosenfeld was forced to announce in 2011 the proposed split of the company into two new entities. Both were to be listed on the New York Stock Exchange, but the company has recently decided to move to NASDAQ, and the split companies will also trade on NASDAQ. The first entity would retain the Kraft foods names and brands, and focus on the North
