851.6. Where, at a particular time, a segregated fund trust has property that was not funded with premiums paid under a segregated fund policy relating to the trust, the insurer is deemed to have an interest in the trust that is not respect of any particular property or separate source of income.
The cost at a particular time of that interest to an insurer is deemed to be equal to the aggregate of the amount that would be the adjusted cost base, to the insurer, of the property described in the first paragraph at that time that it allocated to the segregated fund prior to 1978 if that interest had been a capital property at all times prior to 1978 and if the rules provided in this chapter had applied to the taxation years 1972 to 1977, and the fair market value, at the time the insurer last allocated it to the fund, of the other property described in the said paragraph at that particular time that the insurer allocated to the segregated fund after 1977.
