Underwood, the CFO of TechCo, Inc., has used ASC 740-30 (APB 23) to avoid reporting any U.S. deferred tax expense on $50 million of the earnings of TechCos foreign subsidiaries. All of these subsidiaries operate in countries with lower tax rates than in the United States. Underwood wants to bring to the United States $10 million in profits from these foreign subsidiaries in the form of dividends. How will this profit repatriation affect TechCos book effective tax rate?
