On 13 July 1972, the department stores of the Cooperative “La Proletaria” in Piombino take fire. The fire destroys the entire building insured by Assitalia and Unipol on equal terms. On 9 November 1973 thanks to the moderating function of Unipol, the claim is paid out about fifteen months after its occurrence. The portion paid by Unipol amounts to a total of over ITL 178m.
