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
