A specialist commercial portfolio had written JPY6.2 billion of annual gross premium before we decided to stop renewing it. The expected economics of new commitments no longer met our appetite after claims and service costs were examined. Underwriting leadership recommended the change, and I prepared its financial consequences with the claims and operations teams. The decision concerned future business; it did not cancel the policies and claims already on our books.
An early cost proposal assumed that most support could be removed as premium volume fell. I asked for the remaining workload by activity: open claims, correspondence, records, complaints and reporting. The resulting plan retained eighteen experienced colleagues and a JPY240 million first-year operating budget. Some staff would support the runoff directly and others preserve access to systems and specialist knowledge needed by the team.
Commercial colleagues worried that retaining the cost would make the exit look indecisive. I argued that an unfunded service tail would make it incomplete. We agreed that the team and budget would be reviewed against work remaining, rather than a fixed percentage reduction tied to the disappearance of new premium. The board accepted the smaller future book and the continuing operating commitment together.
In the first year, the open-file count in the monitored cohort declined from 3,100 to 2,240. That count was not a measure of the value of remaining liabilities, and we did not use it to claim that the same proportion of financial risk had disappeared. The service team remained in place. New developments and complex files could continue to demand substantial effort even as simpler cases closed.
The decision gave up a visible volume contribution before all of its costs could fall. I would involve people planning even earlier in another exit, because an experienced colleague's uncertainty about their future can become a service risk long before their departure. The economics of runoff include the ability to keep capable people doing work whose commercial launch story has already ended.
