His Honour also accepted the evidence of Mr Young as to the value of the business as at 28 October 1988 on the basis that condition (p) prevented the use of the boardroom and the annex. On the assumption that those parts of the premises returned 15.28 per cent of the revenue of the business, Mr Young estimated that the lawful revenue of the business was $1,863,840 which, based on the 45 per cent industry average, provided a hypothetical profit of $838,728 for the year. From this figure, Mr Young deducted an annual rental of $406,690, which represented 21.82 per cent of the estimate of the modified revenue for the year, the same percentage which the rent of $480,000 bore to the revenue of $2,200,000. Mr Young then applied the capitalisation rate of 30 per cent to derive a gross value of $1,440,127 from which he deducted $600,000 for the estimated payout figure for the leased chattels, leaving a value of $840,127. The difference between this value and the value of $1,100,000, based on the unrestricted use of the boardroom and the annex, was $259,873. Northrop J accepted Mr Young's analysis of the figures and, after rounding off the various figures, held that Kizbeau was entitled to damages of $265,000 for the difference between what it paid for the business and its true value as at that date.
