on a restructuring of a corporation in financial difficulty ("Y Ltd.") which owes to X Ltd. a trade receivable which was included in X Ltd.'s income in a previous taxation year, X Ltd. converts the trade receivable into common shares of Y Ltd. X Ltd. is entitled to a deduction under s. 20(1)(p) equal to the difference between the amount of the trade receivable and the fair market value of the common shares of Y Ltd. If X Ltd. should dispose of any of those common shares for less than the pro rata amount of the trade receivable from which they were converted, X Ltd. would not be entitled to claim an amount under s. 20(1)(p) because the amount would no longer relate to the trade receivable.
