1 Mod_24_10 Introducing Loss of Profits as a Relevant Damage within the Limitation of Liability Provisions

2 By default as the primary central party in the SEM, SEMO and its activities have being used both in the illustration of Modification Proposal Mod_24_10 and in this presentation to the Modifications Committee.
