146.2. The maximum amount of surplus assets that may be appropriated to the payment of employer contributions shall be the lesser of the surplus assets of the pension plan as determined on a funding basis and the surplus assets as determined on a solvency basis in the last actuarial valuation of the whole plan, reduced to take into account the value of the additional obligations arising from any amendment to the plan which, having been made after the last actuarial valuation of the whole plan, has not entailed the determination of an improvement unfunded actuarial liability.
In the case of a pension plan to which Chapter X does not apply, the maximum amount shall be limited to the portion of the assets which exceeds the value of the obligations arising from the plan, assuming that the plan is terminated.
