Retroactive date

UK: Date that defines the extent of cover in time under claims made liability policies. Claims resulting from occurrences prior to the retroactive date are not covered notwithstanding the notification of claims during the policy period. Retroactive dates are commonly stated to be the inception date of the first year of cover. See ‘NOSE.
***
REINSURANCE: The date on a claims made policy or reinsurance contract which triggers the beginning period of coverage for occurrences commencing prior to the effective date of the policy. A retroactive date is not required. If one is shown on a claims made policy, any claim made during the policy period on a loss that occurred before the retroactive date will not be covered. In reinsurance, losses occurring before the contract term are sometimes covered by the addition of “retroactive” coverage to the contract.

The date that defines the extent of coverage in time under claims-made liability policies. Claims resulting from occurrences prior to the policy’s stated retroactive date are excluded.

Retroactive insurance

Cover for a loss that has already occurred, e.g. a major fire, but for which the severity of the loss is uncertain. The insured pays a high premium to substitute certainty for the uncertain outcome. The insurer is attracted by the investment potential of a high premium pending settlement of the claims.

Retroactive Period

In health Insurance, a period of time at the onset of an injury or disease during which no benefits are payable unless the injury or disease causes disability which extends beyond the retroactive period. If disability last longer than the retroactive period, then benefits are payable retroactively from the first day of disability.
