The CFS Index is compiled from different sub-indices. Panel participants are asked questions about four different business parameters: transaction volume, profits, employment and investments, The answers may be given as “positive”, “neutral”, or “negative” and a response is requested for the previous and the current quarter. 

All participants are allocated to two branch-specific groups. Within each group, a balance of the share of positive and negative responses is evaluated and transformed into performance data. These performance data are then aggregated in order to constitute the CFS Index. Due to construction, the maximum index value is 150, the minimum index value is 50; a value of 100 signalizes a neutral business sentiment.
