We do not use one but several business registers. The databases are not the same for non Financial corporations, Insurance companies and Financial intermediaries. o Non-financial sector: merge of a database on balance-sheet and income statements with another database of financial links for resident firms; these databases come from Banque de France and the French National Statistical Institute, INSEE ;o Financial sector (financial intermediaries and insurance companies): data come from the French financial supervision authority (ACPR), which provides balance-sheets and financial links.
