There have been many Australian demergers in the past 15 years. Generally, demergers take place as management expect a demerged company will be worth more as an independent entity rather than being part of a larger business. Sometimes the motivation for a demerger comes from the desire to separate out a "bad" business so that an unfettered "good" business can shine through to investors.
Wesfarmers is described as a diversified industrial. The business has a significant list of subsidiaries. In 2007, Wesfarmers acquired Coles Group for $22 billion. It was the largest corporate takeover in Australia at the time. The acquisition was $17 ex dividend per share. This represented a 48.4% premium on Coles shares.
