# Commission Decision of 8 May 2012 on State aid SA.22668 (C 8/08 (ex NN 4/08)) (notified under document C(2012) 3025) (Only the Spanish text is authentic) (Text with EEA relevance) (2013/126/EU), Division 1: Amadeus data

Extent: E+W+S+N.I.

Amadeus is a comprehensive, pan-European database containing financial information on over 11 million public and private companies in 41 European countries provided by Bureau van Dijk (BvD) Electronic Publishing. BvD is one of the world’s leading providers of firm level balance sheet data, with Europe being most extensively covered.
The median is the number separating the higher half of a sample from the lower half. If the observed values are arranged in either ascending or descending order, the median is the value in the middle.
The arithmetic mean (average) is the sum of all the observations divided by the number of observations.
For many distributions, the median and mean coincide. Empirically, the two may differ substantially if, despite large sample size, the observed distribution is skewed (e.g. because it contains a number of outliers, i.e. extreme observations).
The data we present below is characterised by values for the mean that are higher that the median (positive skewness). Since the mean is sensitive to outliers, we focus on the median instead. Note that this choice leads to a finding of lower returns as compared to using the sample average.
