(B) Matching expense amount. The term matching expense amount means the lesser of the total amount of the UPL interest expense taken into account directly or indirectly by the UPL debtor for the taxable year with respect to an upstream partnership loan or the total amount of the distributive shares of the UPL interest income of the UPL debtor (or any other person in the same affiliated group as the UPL debtor) with respect to the loan. (C) Upstream partnership loan. The term upstream partnership loan means a loan by a partnership to a person (or any person in the same affiliated group as such person) that owns an interest, directly or indirectly through one or more other partnerships or other pass-through entities (as defined in 1.904-5(a)(4)(iv)), in the partnership. (D) Upstream partnership loan debtor (UPL debtor). The term upstream partnership loan debtor, or UPL debtor, means the person that has the payable with respect to an upstream partnership loan. If a partnership has the payable, then any partner in the partnership (other than a partner described in paragraph (e)(4)(i) of this section) is also considered a UPL debtor. (E) Upstream partnership loan interest expense (UPL interest expense). The term upstream partnership loan interest expense, or UPL interest expense, means an item of interest expense paid or accrued with respect to an upstream partnership loan, without regard to whether the expense was currently deductible (for example, by reason of section 163(j) or the election to waive deductions pursuant to 1.59A-3(c)(6)). (F) Upstream partnership loan interest income (UPL interest income). The term upstream partnership loan interest income, or UPL interest income, means an item of gross interest income received or accrued with respect to an upstream partnership loan. (vi) Examples. The following examples illustrate the application of this paragraph (e)(9). (A) Example 1(1) Facts. US1, a domestic corporation, directly owns 60% of PRS, a foreign partnership that is not engaged in a U.S. trade or business. The remaining 40% of PRS is directly owned by US2, a domestic corporation that is unrelated to US1. US1, US2, and PRS all use the calendar year as their taxable year. In Year 1, PRS loans $1,000x to US1. For Year 1, US1 has $100x of interest expense with respect to the loan and PRS has $100x of interest income with respect to the loan. US1's distributive share of the interest income is $60x. Under paragraph (e)(2) of this section, $75x of US1's interest expense with respect to the loan is allocated and apportioned to U.S. source income and $25x is allocated and apportioned to foreign source foreign branch category income. Under paragraph (h)(4)(i) of this section, US1's share of the total value of the loan between US1 and PRS is $600x.
