US chocolate maker Hershey is considering making an offer of $17 billion for UK confectionery firm Cadbury, according to reports. It is believed that Hershey has lined up funding from Bank of America and JP Morgan in order to make a solo approach to rival the US food giant Kraft. Reports last week indicated that Hershey was planning to team up with Italian chocolate maker Ferrero to make an offer for Cadbury, but according to the Wall Street Journal, the Pennsylvania-based firm will now pursue its bid alone.
