CATASTROPHE DEDUCTIBLE- A percentage or dollar amount that a homeowner must pay before the insurance policy kicks in when a major natural disaster occurs. These large deductibles limit an insurer’s potential losses in such cases, allowing it to insure more property. A property insurer may not be able to buy reinsurance to protect its own bottom line unless it keeps its potential maximum losses under a certain level.

COINSURANCE- In property insurance, requires the policyholder to carry insurance equal to a specified percentage of the value of property to receive full payment on a loss. For health insurance, it is a percentage of each claim above the deductible paid by the policyholder. For a 20 percent health insurance coinsurance clause, the policyholder pays for the deductible plus 20 percent of his covered losses. After paying 80 percent of losses up to a specified ceiling, the insurer starts paying 100 percent of losses.
