Time at Risk == Value at Risk (if we replace value by time)

E.g. An insurance company’s 90% TaR is 3 year for liquidity risk - That means that for 3 years the insurer under the current financial structure would be 90% safe

Time at Risk (TaR for short): is the maximum period of time that an adverse event would not occur. We calculate it as follows:

The units are cases/person-year
