calculation of the arithmetical average of that Member State's population and surface area shares of the total population and surface area of all the eligible Member States. If, however, a Member State's share of total population exceeds its share of total surface area by a factor of five or more, reflecting an extremely high population density, only the share of total population will be used for this step;
adjustment of the percentage figures so obtained by a coefficient representing one third of the percentage by which that Member State's GNI per capita (measured in purchasing power parities) for the period 2008-2010 exceeds or falls below the average GNI per capita of all the eligible Member States (average expressed as 100 %).
