The Credit Register information used here is based exclusively at the transaction or loan level, not at the level of borrowers. A given borrower may enter into several loans with the same bank or with different banks. As some characteristics of the loans cannot readily be aggregated for a given borrower (collateral, maturity, type of instrument), in order to distinguish their impact it is essential to perform the analysis at the level of each loan. If all of a borrower’s loans with various different banks are grouped together it also becomes impossible to distinguish differences in behaviour between.
