The annual cash and in-kind contributions of Members and Observers shall be determined using the following variables: Scale of contribution; DARIAH unit of ownership, in short: DARIAH unit; Cash budget; In-kind budget; The Members and Observers selected by the General Assembly to calculate the DARIAH unit. The scale of contribution for a country shall be calculated with the following formula: divide the GDP of the country by the sum of the GDPs of the Council of Europe Member States, and then round the scale of contribution to two figures after the decimal point. For countries that join DARIAH ERIC as Observers, their scale of contribution shall be half of what it would have been if they had joined as Members. The DARIAH unit for the cash budget (x) shall be calculated with the following formula: divide the cash budget by the sum of the scales of contribution of the Members and Observers selected by the General Assembly to calculate the DARIAH unit for the cash budget. The DARIAH unit for the in-kind budget (y) shall be calculated with the following formula: divide the in-kind budget by the sum of the scales of contribution of the Members and Observers selected by the General Assembly to calculate the DARIAH unit for the in-kind budget. Contributions for cash and in-kind shall be calculated according to the following formula: (a) Cash contribution The scale of contribution for a country is multiplied by the DARIAH unit for cash (x), and the result is then rounded up the nearest hundred euro. (b) In-kind contribution The scale of contribution for a country is multiplied by DARIAH unit for in-kind (y), and the result is then rounded up to the nearest thousand euro. The General Assembly may change the cash and in-kind budgets every year, and the reference GDP after three years, in accordance with the weighted voting system as defined in Articles 10(14) and 10(16). If the General Assembly does not change the variables of the budget (as described in principle 1 above), the annual contribution shall be the contribution of the previous year with an annual increase of two per cent to compensate for inflation and increase in costs. Intergovernmental organisations shall pay the contribution according to their status as Member or Observers. The contribution for entities joining during the course of a year shall be proportional to the number of remaining months in that year, starting on the first day of the month of joining. The annual contribution for Members or Observers not initially committing for five years shall be raised by twenty five per cent, as long as the commitment for the remaining period has not been made. If a commitment for the remaining part of the five years is made or if the Member or the Observer stays for five years, arrangements shall be made to ensure that the Member or the Observer shall not pay more in total than the standard contribution for those five years.
