Deutsche Wohnen, one of the leading listed real estate companies in Germany and Europe, offered to acquire conwert Immobilien Invest, which develops, manages, sells, and leases commercial and residential real estate, for £2bn. The offer was lapsed in April 2015. "Given that the minimum acceptance threshold regarding the takeover offer for Conwert shares has not been reached, the offers for Conwert’s convertible bonds as well as the anticipatory mandatory offer for the relevant shares of (unit) ECO Business-Immobilien AG are no longer effective," Deutsche Wohnen.
