The module provides an example of rating attribution, determining an elementary rating (formed of four degrees of judgment) on the basis of the most common ratios calculated on the business balance sheets: ROE, ROI, ROS, Turnover of invested capital, Degree of financial autonomy, Current ratio, Performance index, Acid-test ratio.
It is possible to customize the rating calculation logic, selecting the ratios to consider and their weight.
This way, users can adapt the rating model to the specific needs of each credit institution. Actually, the Basel 2 framework leaves each bank free to decide which ratios to consider and how much significance to give each one.
