A key consideration during the preparatory phase project DiSSCo Prepare – which laid the foundations for the future Research Infrastructure DiSSCo (Distributed System of Scientific Collections) – was the need to establish a small number of alternative viable financial contribution models and a scalable formula which could be presented to potential funders, with a view to obtaining the minimum financial contribution necessary for DiSSCo to operate, as well as considering how the RI could grow with increased national funding. This report briefly explains the ERIC funding framework – as chosen for DiSSCo – and its legal constraints, in order to explain the key role played by national member contributions in the viability of an ERIC. An essential annex of the statutes that will be signed by all members of the ERIC is the member fee calculation. A proposal for the DiSSCo member fee calculation is set out in this document and is based on three main indicators: economic power (GDP), annual spending in research and development and population size. In the context of DiSSCo – and to ensure the ERIC can function – these indicators are connected to a fixed baseline fee of €50,000, in order to guarantee a minimum significant annual contribution from each participating country and avoid contributions that will be more expensive to manage than to benefit from. This baseline is multiplied by contribution factors which propose different ways to weight the various indicators. The method is established on an ideal scenario, whereby all 27 EU members, as well as the UK, Iceland, Norway and Switzerland sign the DiSSCo statutes and agree to the proposed member contribution calculation, amounting to €4.5 million for the annual budget of the ERIC. This scenario remains highly unlikely; therefore, a scaled approach has been envisaged, meaning the initial engagement of some countries will allow DiSSCo to begin its operation and implement its business strategy, whilst the growth of the ERIC and its activities is likely to evolve proportionally to the number of national members it is able to engage. This report also looks at the ways in which funding could be distributed amongst the DiSSCo members in order to implement decentralised services.
