The UK’s biggest property group, Land Securities, started an auction for its Trillium outsourcing business recently. The business could sell for up to £1.5bn. The property group has had many approaches from interested parties. Macquarie, the Australia-based infrastructure group and Cinven, the private equity investors, are thought to be among them. Analysts have valued the business at between £1bn and £1.5bn. Before a price can be finalised, Land Securities would first need to decide on how to package the business in regards to its debts and assets. Land Securities said it would also consider the benefits of a sale of Trillium against the merits of a de-merger, according to reports.
