A very insightful quote from my colleague Al Liguori regarding how the GILTI tax is creating unexpected increases in taxes for some U.S. companies.  Companies with international operations - even those that are not technology and pharmaceutical firms - must pay very close attention to how the GILTI tax can unexpectedly increase their effective tax rates.  Furthermore, it is imperative that the GILTI tax is appropriately accounted for in a valuation of the company, or there is a risk that the business will be overvalued due to an understated tax rate.
