A risk measure is defined as a mapping from a set of random variables to the real numbers. This set of random variables represents portfolio returns. The common notation for a risk measure associated with a random variable X {\displaystyle X} is ρ ( X ) {\displaystyle \rho (X)} .
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).

Together with risk assessment and risk management, risk communication aims to reduce foodborne illnesses. Food safety risk communication is an obligatory activity for food safety authorities [ 69 ] in countries, which adopted the Agreement on the Application of Sanitary and Phytosanitary Measures .
Credit risk management is a profession that focuses on reducing and preventing losses by understanding and measuring the probability of those losses. Credit risk management is used by banks, credit lenders, and other financial institutions to mitigate losses primarily associated with nonpayment of loans.
At-Risk-Measures such as value at risk, Cash Flow at Risk or Earnings at Risk. Risk adjusted performance measures as RAROC and RARORAC. In summary, it can be concluded that the representation of risk and uncertainty in accounting systems is limited in scope and technique as well as dispersed over different systems.
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]
A coherent risk measure satisfies the following four properties: 1. Subadditivity. A risk measure is subadditive if for any portfolios A and B, the risk of A+B is never greater than the risk of A plus the risk of B. In other words, the risk of the sum of subportfolios is smaller than or equal to the sum of their individual risks.
