FAMOS, which stands for Financial Analysis Model of Small and Medium Enterprises (SMEs), forecasts assets and capital as expressed on the balance sheet, distinguishing between sectors and size classes. In addition, the model generates a number of financial indicators, from which the financial situation of firms can be derived instantly (e.g. liquidity, solvency). The modeling of the size-class structure is the surplus value of the model. The model can be used to analyse the impact of changes in turnover, investments, profits and financial costs on the composition of assets and capital. For instance, an increase of the interest rate of 2 percentage points affects the liquidity and solvency of firms. With FAMOS, it is possible to address the effects of such changes across sectors and size classes.
