Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards: Recently adopted On February 25, 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ASU 2016-02, “Leases” (“ASU 2016-02”). ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, ASU 2016-02 modifies current guidance for lessors' accounting. ASU 2016-02 is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. PMI has identified its lease management system and has identified and evaluated the applicable leases. In addition to the guidance in ASU 2016-02, PMI has evaluated ASU 2018-11, which was issued in July 2018 and provides an optional transitional method. As a result of this evaluation, PMI elected to use the optional transition method, which allows companies to use the effective date as the date of initial application on transition and not adjust comparative period financial information or make the new required disclosures for periods prior to the effective date. Additionally, PMI elected to use the hindsight practical expedient, as well as the package of practical expedients permitted under the transition guidance within the new standard. Upon adoption, PMI recognized lease liabilities and the corresponding right-of-use assets (at the present value of future payments) for predominately all of its operating leases in place at that time. At January 1, 2019, PMI's adoption of ASU 2016-02 resulted in an increase of approximately $0.7 billion on its assets and liabilities in its statement of financial position. ASU 2016-02 did not have a material impact on its results of operations or cash flows. For further details, see Note 18. Leases. On January 1, 2019, PMI elected to early adopt ASU 2018-15 “Intangibles - Goodwill and Other - Internal - Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The adoption of ASU 2018-15 did not have a material impact on PMI's consolidated financial position or results of operations.
