Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Cyber Insurance Retention Exposure to answer this question: estimate retained cyber loss after deductible, coinsurance, limit and expected coverage probability? Enter Modelled gross cyber incident loss, Policy deductible or retention, Policy limit, and 2 other inputs; the calculator shows Expected retained cyber incident loss. Try changing one number and watch what happens to Expected retained cyber incident loss. The answer tells you Expected retained cyber incident loss.
Age 15Explain it to a 15-year-oldConnect it to the formula
Exclusions, sublimits, waiting periods, control warranties and claim disputes must be reviewed in the policy. The rule is Retained loss = gross incident loss − expected insurance recovery. Its input values are Modelled gross cyber incident loss, Policy deductible or retention, Policy limit, Insurer-paid share after retention (%), Probability loss is covered as modelled (%), and the main result is Expected retained cyber incident loss. Try changing one number and watch what happens to Expected retained cyber incident loss.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Retained loss = gross incident loss − expected insurance recovery, evaluated from Modelled gross cyber incident loss, Policy deductible or retention, Policy limit, Insurer-paid share after retention (%), Probability loss is covered as modelled (%) to produce Expected retained cyber incident loss. Exclusions, sublimits, waiting periods, control warranties and claim disputes must be reviewed in the policy. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
