Based on the risk appetite of the respective banks(JP MORGAN and MUFG), how do they each represent risk?

Risk Representation (R). Risk is a highly abstract (unobservable) concept that is poorly understood and communicated by organisations. Having a word for an abstract concept, however, does not always mean that everyone holds the same conception of it. How does the bank represent risk, i.e., what do they refer to when talking (communicating) about 'risk'? As a set of parameters (reasoning)? As an outcome (expectation) As a probability? An event (possibility)? A process (short and long tails)? Is risk represented as a timing (t) issue, a return sequencing issue (order of returns), as volatility (Stdev), correlation (diversification), probability (p), threshold value (value-at-risk, VaR)? Does the representation pay attention to relationship within its structure? Has the representation of risk changed over the time? What caused the change? When people have different representations about risk it makes it hard to communicate about it. Conflicts of interest? How does the organisation communicate risk through language? Language shows what the organisation thinks is possible, appropriate and inappropriate about risk, the values underlying risk philosophy.
