On the basis of these expectations, BGB had granted a large number of commercial real estate loans and, in the period prior to 1999, had set up increasingly large real estate funds with extensive guarantees for which, at the beginning of the real estate crisis in the late 1990s, a valuation adjustment and liability reserves were sorely needed.
Nende alusel andis BGB suures mahus kinnisvaralaenusid tööstusele ja kuni 1999 järjest kasvava mahuga kinnisvarafondidele ulatuslikke garantiisid, mis seoses 90ndate aastate lõpu kinnisvarakriisi algusega nõudis tungivat väärtuste korrigeerimist ja reserve.
