This chapter is to describes with a real case study, how to properly integrate financial quantitative data with operational data. The objective is to generate an integrated risk score from two different data sources: financial data represented by XBRL balance sheets and operational loss data. XBRL is a language for the electronic communication of business and financial data, which is revolutionizing business reporting. In the case study, starting from XBRL balance sheets, it is possible to derive quantitative information such as financial ratios that are useful for measuring credit risk. The chapter presents a methodological proposal followed by a description of the application and the main results achieved. It shows how to integrate financial and operational risk management and, more precisely, credit risk with operational risk, following a two-step approach.
