When is it possible to know whether a Shareholders' Meeting will be held at first, second or third calling?

In the notice calling the Shareholders' Meeting it is explicitly stated if the Shareholders' Meeting will be held in single call or following more than one call.
In the latter case, as a result of legislative provisions consequent to Legislative Decree No. 27/2010, it is no longer possible to know with certainty in advance the date on which the Shareholders' Meeting will be held.
However, with regard to Eni's shareholder structure and if more than one call is provided, the ordinary Shareholders' Meeting is normally held on second calling and the Extraordinary Meetings on third calling.
