Since the payments received in the taxable year of the sale do not exceed 30 percent of the selling price and the sales price exceeds $1,000, A may report the income received on the sale of his corporation X stock on the installment method. A elects to report the income on the installment method. The gross profit to be realized when the corporation X stock is fully paid for is 10 percent of the total contract price, computed as follows: $100,000 gross profit (i.e., $1 million contract price less $900,000 basis in corporation X stock) over $1 million contract price. However, since subparagraph (2) of this paragraph also treats the 250 corporation Y registered bonds as a payment for purposes of reporting income, A must include $25,000 (i.e., 10 percent times $250,000) in his gross income for calendar year 1970, the taxable year of sale.
For purposes of subdivision (ii) of this subparagraph, the determination as to whether there exist obligations of a comparable character depends upon the particular facts and circumstances. Factors to be considered in making such determination include, but are not limited to, substantial similarity with respect to the presence and nature of security for the obligation, the number of obligations issued (or to be issued), the number of holders of such obligation, the principal amount of the obligation, and other relevant factors.
