4. Wheelco, a foreign corporation, manufactures motorcycles for sale worldwide. Wheelco markets its motorcycles in the United States through Wheely, a wholly-owned U.S. marketing subsidiary that derives all of its income from U.S. business operations. Wheelco also has a creditor interest in Wheely, such that Wheely's debt to equity ratio is 3 to 1, and Wheely makes annual interest payments of $60 million to Wheelco. The results from Wheely's first year of operations are as follows:



Sales ............................................................................................. $180 million
Interest income ............................................................................... $6 million
Interest expense (paid to Wheelco)................................................................................................. $6 million
Depreciation expense....................................... .............................. ($30 million)
Other operating expenses................................. .............................. ($81 million)
Pre-tax income ................................................. ............................ $15 million

Assume the U.S. corporate tax rate is 35%, and that the applicable tax treaty exempts Wheelco's interest income from U.S. withholding tax. Compute Wheely's interest expense deduction.
