40. Susan L SmithLCUK30.06.2004 Budget

41. Susan L SmithLCUK30.06.2004 Requested by Country, total request = €11.25M Total budget = €28 M

42. Susan L SmithLCUK30.06.2004 Requested by Country/UK Institute

43. Susan L SmithLCUK30.06.2004 Requested By Work Package

44. Susan L SmithLCUK30.06.2004 Outcome of the bid EUROTeV ranked second in the scientific evaluation Recommended approval of 9M€ which is less than the 11.2M€ bid The recommendation is that the host institutes makeup the shortfall to ensure that the scope of the project is maintained! Overall the UK host contribution is around twice the UK request. This is around twice the relative contribution of other countries which generally commit just over the matching funds required by the bid call.
