Age 15Explain it to a 15-year-oldConnect it to the formula
Attachment points, limits, reinstatements, counterparty risk, timing and exclusions control actual recovery. The rule is Reinsurance coverage ratio = qualifying recoverables ÷ selected gross claim exposure. Its input values are Selected gross catastrophe claim exposure, Expected treaty reinsurance recoverables, Expected facultative recoverables, Expected reinstatement and recovery cost, Selected net exposure target, and the main result is Qualifying reinsurance coverage ratio. Try changing one number and watch what happens to Qualifying reinsurance coverage ratio.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a macroeconomics relationship while holding unmodelled conditions constant. The implemented relation is Reinsurance coverage ratio = qualifying recoverables ÷ selected gross claim exposure, evaluated from Selected gross catastrophe claim exposure, Expected treaty reinsurance recoverables, Expected facultative recoverables, Expected reinstatement and recovery cost, Selected net exposure target to produce Qualifying reinsurance coverage ratio. Attachment points, limits, reinstatements, counterparty risk, timing and exclusions control actual recovery. The result depends on comparable definitions, units, populations and time periods. It estimates a relationship; it does not establish causation or replace current primary data.
The economic question
Measure qualifying reinsurance recoverables against selected gross catastrophe claim exposure.
Why this relationship is useful
Attachment points, limits, reinstatements, counterparty risk, timing and exclusions control actual recovery.
Inputs that must be comparable
- Selected gross catastrophe claim exposure.
- Expected treaty reinsurance recoverables.
- Expected facultative recoverables.
- Expected reinstatement and recovery cost.
- Selected net exposure target.
Use one market, firm, population and time period throughout; mixing definitions can make a correctly calculated number economically meaningless.
The model
Reinsurance coverage ratio = qualifying recoverables ÷ selected gross claim exposure
From inputs to output
The calculator combines Selected gross catastrophe claim exposure, Expected treaty reinsurance recoverables, Expected facultative recoverables, Expected reinstatement and recovery cost, Selected net exposure target and reportsQualifying reinsurance coverage ratio together with Selected net catastrophe exposure, Net exposure above selected target. Change one assumption at a time to identify what actually drives the estimate.
How to read Qualifying reinsurance coverage ratio
Read the sign, magnitude, unit and period together. The result quantifies the relationship in “measure qualifying reinsurance recoverables against selected gross catastrophe claim exposure”; it does not by itself prove that one input caused another.
Where interpretation can fail
Do not use the result when the input definitions, units or formula assumptions do not match the real situation. This is an educational model, not financial, investment, tax or policy advice; verify material decisions against primary data and professional guidance.
