I think it is appropriate to report insurance cash values as assets. Without looking anything up, I think there are parts of the instructions that talk about contracts with insurance companies that do NOT require reporting, but that is where a plan is offloading liabilities, e.g. buying an annuity contract.
In real life, purchasing a life insurance contract in a plan is absolutely just a transfer from one asset to another - the policy will happen to have little or no value at the end of the first year, but so be it. For anyone who thinks they shouldn't be reported, then the question is: suppose the insurance policy is surrendered and the money is invested elsewhere, how do you report that sudden influx of money?
As far as what to do with a policy for a participant entitled to a distribution, now you will experience why insurance in a plan is so bad - policies effectively get trapped. If the participant wants to keep the policy, and they take it as a distribution, the cash value is taxable (minus accumulated PS-58 costs, if anyone was keeping track of that). They could just surrender it and roll over the proceeds. They can buy the policy if they have cash sitting around, and the money that was used to pay for the policy can be rolled over. Or they can borrow most of the money out of the policy (the loan proceeds become part of the rest of the account and can be rolled over) and then take the stripped-out policy as a taxable distribution (maybe the cum PS-58s will cover some or all of it) or buy it for the reduced cash value. Either way you wind up doing a lot of work...
