What is follow the actions clause in reinsurance?

"Follow-the-fortunes" is a fundamental doctrine of reinsurance which provides generally that a reinsurer must follow the underwriting fortunes of its cedant (reinsured) and is thus bound by the claims-handling decisions of its reinsured, provided there is no evidence of fraud, collusion with the insured, or bad faith. It is a burden-shifting doctrine which allows the cedant (reinsured) the freedom of making good-faith claims decisions without the fear of having to relitigate those decisions with its reinsurer. This term is used inter-changeably with "follow-the settlements".
