3. Financial Ratios

• User story: As a CA I would like to be able to assess the economic and financial standing of the Economic Operators (EO) for which I would need to be able to require the EOs provide different types of financial ratios for the past N years.

• Status: Draft

• Requirements:

• The CA SHOULD be able to specify the number of the past recent years for which it will require Ratios.

• To specify a Ratio, the CA MUST use one of the codes defined by BACH (see [https://www.bach.banque-france.fr/](BACH Banque France), and BACH-DataBase-Ratios.xlsx).

• Agreed types of Ratios that are not defined by BACH could be added to the BACH's list.
