9Calculation of amount of compensatory payment
(1)In calculating the compensatory payment in respect of which notice may be served under section 8(1) of this Act, there shall first be determined the sum of money which would, if invested in two and a half per cent. Consolidated Stock at the middle market price at the close of business last preceding the appointed day, produce an annual sum equal to the feuduty.
(2)Unless the feuduty was, at extinction, a cumulo feuduty the sum so determined shall be the compensatory payment.
(3)If the feuduty was, at extinction, a cumulo feuduty the former superior shall, after determining that sum, allocate it among the former vassals in such proportions as are reasonable in all the circumstances; and an amount which is so allocated to a former vassal shall be the compensatory payment for that former vassal.
(4)If the feuduty was, at extinction, a cumulo feuduty wholly or partly apportioned among the former vassals, then for the purposes of subsection (3) above the proportions of an allocation shall be presumed reasonable in so far as they accord with that apportionment.
