Validate Qualitative Factors With Backtesting
Backtesting the ALLL refers to comparing the actual outcome of credit losses with model forecasts during a defined period to validate the accuracy of the model. In other words, institutions can retroactively prove that their ALLL levels were appropriate with actual incurred losses.
If an institution has a sound backtesting policy in place and can validate the accuracy of its model, this can serve as further evidence when defending any future qualitative analyses within the ALLL calculation.
