2. Pursco is a domestic corporation that distributes scientific equipment worldwide. During the current year, Pursco had $100 million of sales, a gross profit of $40 million, and incurred $30 million of selling, general and administrative expenses (SG&A), for taxable income of $10 million. Purscos sales include $20 million of sales to foreign customers. The gross profit on these foreign sales was $10 million. Pursco transferred title abroad on all foreign sales, and therefore the entire $10 million is classified as foreign-source income. A time management survey was recently completed, and indicates that employees devote 90% of their time to the companys domestic operations and 10% to foreign operations. Compensation expenses account for $20 million of the $30 million of total SG&A expenses. Assume Purscos $10 million of taxable income is subject to U.S. tax at a 35% rate. Compute Purscos foreign tax credit limitation under the following independent assumptions. a. Pursco determines the amount of SG&A expenses allocable to foreign-source income using gross sales as an apportionment base. b. Pursco determines the amount of SG&A expenses allocable to foreign-source income using gross profit as an apportionment base. c. Pursco determines the amount of SG&A expenses allocable to foreign-source income using time as an apportionment base for the compensation component of SG&A, and gross sales as an apportionment base for the all other SG&A expenses.
