In November 2009, the Office of Fair Trading announced a study into corporate insolvencies, with particular focus on pre-pack administrations, to report on whether the insolvency market is operating efficiently, with enough freedom of competition between insolvency practitioners and whether consumers and creditors are being treated as fairly as possible. An example of a pre-pack is the sale of the assets of Cobra Beer to Coors immediately after Cobra Beer entered administration. This allowed the brand to continue and saved jobs, but also left suppliers out of pocket by an estimated £75 million.
