(ii) U.S.-connected liabilities. Because Z's U.S. booked liabilities of $400 exceed its U.S.-connected liabilities by $100, all of Z's interest expense allocable to its U.S. trade or business must be scaled back pro-rata. To determine the scaling ratio, Z divides its U.S.-connected liabilities by its U.S. booked liabilities, as required by paragraph (d)(4) of this section. Z's interest expense is scaled back pro rata by the resulting ratio of 3/4 ($300 $400). Z's income, expense, gain or loss from hedging transactions described in paragraph (d)(2)(vi) of this section must be similarly reduced.
