The questions in the monthly surveys are harmonised with the requirements and recommendations of international institutions (European Commission DG ECFIN, OECD) and results of the surveys are part of materials of these institutions and are used for international comparisons. The questionnaire for business cycle surveys is very simple so that the management of an enterprise can fill it in fast and answers can be obtained immediately even as far as urgent and topical questions are concerned. The questionnaires contain questions regarding expected and running tendencies. Questions are put in the form of evaluation scales, mostly with three possible alternatives of answers such as improvement, constancy, worsening, and the like. Evaluation of the results is made as a summary of the questions in individual alternatives, a clear expression of tendencies is business cycle balance, which is the difference between the answers "improvement" and "worsening" expressed in percents. The higher the positive balance of answers the more optimistic is the evaluation of the answer obtained. Since January 2002, the consumer confidence indicator has been composed of four indicators (expected financial situation of consumers, expected total economic situation, expected total unemployment (with inverted sign) and savings expected in 12 months to come). Since January 2003, the confidence indicators have been presented as basic indices, the base being the average of 1995.
