At the risk of being in opposition to everyone on this thread so far, can I just point out a few things about this deal:
Kraft currently have a very small confectionery business - so buying Cadbury expands their portfolio. Most M&A deals with big job losses are in that situation because there is a big cross over in what their current business does and what the new acquisition does (eg Nestle and Rowntree) So logically, I would not assume there will be massive job losses in the actual manufacturing area of the business. There probably will be losses in management/Coporate/Head Office areas - so is everyone worried about the poor old CFOs/Marketing Directors etc etc, where there are duplicate roles in both organisations?
Re recipies/chocolate tastes - Cadbury already makes different tasting chocolate for different markets...based on what the local market preference is. IIRC, there are 2 production lines for Creme Eggs - UK and rest of world, because the taste for sweetness differs. And yes, they are significant in the Emerging Market countries, including India - which has yet another taste profile. I don't know why Kraft would radically change this, as it would affect sales. And brand perception...thereby defeating the purpose of buying a successful, brand-led company, no?
Yes, people will make money out of this deal. And if anyone here has a pension, there's a fair chance that your pension pot could be positively impacted by the deal as well...so I don't think it's as straightforward as Nasty Hedgefunders and Directors Making a Packet at Everyone Else's Expense. They are running a business, and it's part of their fiduciary duty to provide returns to shareholders, and ensure the successful implementation of business decisions.
In the interests of full disclosure, I should point out that I used to work for Cadbury, and am a (very small) shareholder. I am not overjoyed that a UK company has been taken over by a US conglomerate - but there are worse things that could happen....eg Hershey could be taking them over!
