A consortium of Roman entrepreneur Gaetano Caltagirona and insurance giant Generali has launched a non-binding offer for the 49% stake in the MPS real estate portfolio that the Italian financial group put up for sale last year. Italian paper Il Sole 24 Ore reported on Thursday that the MPS assets consist of around 500 buildings mostly in the Tuscany and Lombardy regions and with a market value totalling EUR 1.4bn.
