I just re listened to the aasb 17 briefing from last year. The last question ask during the briefing basically answered my question from before.

At a high level HLI recognises that it can take up to 15 years for a policy to clear the books, after this period it won't require any payout (?), so risk and outflow because 0? and remaining CSM is fully earned as Revenue. If the policy is cancelled, then the Contract Service Margin, previously called Unearned Premium, will be spread to the remaining years of the 15 years. And cause the policy has been cancelled, the risk adjustment and cash outflow would be 0 going forward hence the CSM should be consistent.

Not sure if my understanding is correct, especially for why they choose 15 years for the max duration of the contract? Thought insurance would be the max loan duration? so up to 30 years?
