Foreign Subsidiary – Fair Value Adjustment Intangible

When calculating the goodwill of a foreign subsidiary, an aspect involves conducting fair value adjustments net of tax of the net assets of the acquiree. Some common adjustments include PPE and intangibles. Normally when preparing goodwill of a foreign subsidiary, you would make the calculations all in the functional currency of the acquiree (If UK company acquired US company, the goodwill is calculated in USD). For PPE you would make the adjustment net of tax using the tax rate of where the PPE is located (US), which makes sense. However, what tax rate would you apply for an intangible? i.e. brand name. Would that still be the US tax rate?
