5. Common Fund budget projections 51 Oct 2014, indico: 3360793rd FRC meeting, Antti Onnela, CERN-PH-DT Balance in 2015-2017 assumes that all contributions of those years are paid. Notes: 1. No nominal contributions in 2011, only voluntary ones. CLOUD M&O MoU signed in 2012. 2. CF budgeted income bases on 50 k€/y & 20 k€/y for cat.1 & 2 partners, respectively. 3. When account balance positive may reduce contributions by factor two to 25 k€/y & 10 k€/y (cat.1 & 2). 4. In 2012 no CF payment by Lisbon, Leeds and Manchester, 10 kE by Vienna, and 30 kE by Karlsruhe. 70 kE extra contribution by Frankfurt to pay CLOUD dewars (of which 44 kCHF N2 dewar included here in income and expenditure, but paid directly from Frankfurt team account). 5. In 2013 no CF payment by Vienna. Lisbon requests 5 kEuro payment. Karlsruhe contributed 20 kE in-kind for permanent SIMONE instrument. Not shown in income nor in expenditure. 6. No CF payment from Frankfurt and IfT until 2013 (BMBF contribution). 7. In 2014 Lisbon requests 5 kEuro payment, Karlsruhe requests passing to cat 2. and 20 kEuro payment. 8. No CF payment from PSI until 2015 (chamber construction debt). PSI contribution in 2015: 42 kEuro, as 8 kEuro to complete the chamber constr debt payment.

6. Common Fund budget projections 61 Oct 2014, indico: 3360793rd FRC meeting, Antti Onnela, CERN-PH-DT Ideal scenario: All contributions paid in time, and the delayed ones in 2015- 2016. Unacceptable scenario: 100 kE unpaid, every year. Debt paid only by ~2021! Expenditures must stay low (= no major technical problems allowed during 6 years!) Debt paid within 2016. Shows that the current Nominal contributions vs. Expenditures is not wrong, if respected by all.

9. Big accumulated debt: -842’351.76 CHF ≈ 683’000 Euro at end 2013. This debt and the unpaid/delayed contributions have seriously compromised the use of the CLOUD Common Fund account in 2014 and getting CLOUD ready for the 2014 run. Positive: Annual expenditures to keep CLOUD operational are going down: A substantial backlog, 260 kEuro, of unpaid contributions [kEuro]: 1 Oct 2014, indico: 3360793rd FRC meeting, Antti Onnela, CERN-PH-DT9 Summary of the current status Year201120122013201420152016 [kEuro]541506386260 (est.)230 (est.) 201220132014TotalComment Innsbruck20 60New invoices to U of Innsbruck, not IONICON Karlsruhe20/50 Requests passing to 20 kE/year (Cat 2.)

10. Expenditures: Budget needed for CLOUD M&O in 2015 is estimated at 230 kEuro. Requesting the FRC to approve this budget. Contributions: CLOUD needs to have a clear plan on covering the expenditures AND reimbursing the debt. Basically, the plan should be simple and inventing nothing new: Every CLOUD partner pays its agreed contributions: 50 kEuro for cat. 1 and 20 kEuro for cat. 2 partners. Backlog of unpaid contributions (total 260 kEuro) paid in 2015-2016. Expenditures maintained at the strict necessary to keep CLOUD operational, safe and achieving its scientific goals. Estimated at 230 kEuro / year, for 2015 and 2016.  With this plan the debt would be paid within 2016. If this plan is not realistic, what needs to be corrected in it? What is an acceptable and achievable reimbursement schedule? 1 Oct 2014, indico: 3360793rd FRC meeting, Antti Onnela, CERN-PH-DT10 2015 and beyond
