There are no duplicates in firmbasecore. In firmbase, aside from 'AmundiPrivate Equity Funds SA'was the only duplicate, which but we dropped the one with the earlier founding date when we cleaned firmbase. Amundi has 2 branch offices in the same city (Bucharest) but different zip codes, which is why there are different counts when we use firmname/firmname,bocity as a key vs firmname, bozipas our key. We might drop "Amundi" from firmbasecore, as well as branchofficecore.
