Sep. 30, 2017
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: Income tax provisions for jurisdictions outside the United States of America, as well as state and local income tax provisions, were determined on a separate company basis, and the related assets and liabilities were recorded in PMI’s condensed consolidated balance sheets. PMI’s effective tax rates for the nine months and three months ended September 30, 2017 were 27.1% and 28.5%, respectively. PMI’s effective tax rates for the nine months and three months ended September 30, 2016 were 28.1% and 27.7%, respectively. PMI estimates that its full-year 2017 effective tax rate will be approximately 28%. The effective tax rate for the nine months ended September 30, 2017 was favorably impacted by the tax benefit of a legal entity restructuring ($61 million). Excluding the effect of the legal entity restructuring, the change in the effective tax rate for the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, was primarily due to earnings mix by taxing jurisdiction and repatriation cost differences. The effective tax rates are based on PMI’s full-year earnings mix projections by taxing jurisdiction and cash repatriation plans. Changes in currency exchange rates, earnings mix by taxing jurisdiction, or cash repatriation plans could have an impact on the effective tax rates, which PMI monitors each quarter. Significant judgment is required in determining income tax provisions and in evaluating tax positions. PMI is regularly examined by tax authorities around the world and is currently under examination in a number of jurisdictions. The U.S. federal statute of limitations remains open for the years 2013 and onward. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from three to five years. It is reasonably possible that within the next 12 months certain tax examinations will close, which could result in a change in unrecognized tax benefits, along with related interest and penalties. An estimate of any possible change cannot be made at this time.
