Mo. U – Signatures of funding agencies Table as of July 2013 COMPASS FRC – November 29, 2013 6

Costs planning Changes versus original tables in Mo. U: - US: Only one drift chamber is funded, instead of two. Part of existing straws will be kept. This is fine for 2014 -2015. - Germany : 57 k. CHF for the ECAL 1 upgrade were paid from the Collaboration funds, and consequently are removed from the German contribution (see Table Sub-detector B, Mo. U page 30) Spending profile unchanged COMPASS FRC – November 29, 2013 7

Technical Coordinator The Collaboration Board has identified a candidate, J. Bernhard, and proposed him to CERN, for the role of Technical Coordinator. J. B. would be ready to start the job by March 1 st, 2014. We are confident that the issue is close to be solved. This is an important step for the forthcoming installations and runs.
