as part of the BFSE network, Lombardy Region piloted an SROI tool on the Polpetteria Ciccilla social co-operative restaurant in Milan. On 24 Sep 2012, also in Milan, they presented the results during a seminar organised by Formez as part of the 'Diesis' (no relation to DIESIS sc!) project.
The SROI by the way is 2.05 = a 105% return.
