Banking is at the forefront of the effort to quantify and measure operational risk and as such can be role model beyond the financial services industry. The Basel Committee of the Bank for International Settlements (BIS) has created a new capital accord, known as Basel II. Basel II requires banks to establish an operational risk management (ORM) framework and compute an explicit capital charge for operational risk once it is adopted. This chapter from Goverance, Risk, and Compliance Handbook, by Anthony Tarantino, outlines different approaches, tools, and guidance on operational risk management for financial services companies.
