Germany's Metro is not planning to sell its property assets, despite market rumours that a private equity firm would be interested in a deal, Wolfgang Baumgartinger, head of real estate at Metro Cash & Carry told news agency Reuters on Wednesday. 'There have been quite a few rumours recently, but I guess this happens to all the companies that have a lot of assets in real estate. There is nothing substantial behind it in my view', he said. The world's third-biggest retailer by sales built its business by investing in its own properties and this is not going to change, he added.
