Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements Not Yet Adopted	In February 2016 the FASB issued ASU 2016-02, Leases (Topic 842). This update requires an entity to recognize assets and liabilities for leases with lease terms of more than 12 months on the balance sheet. We plan to adopt this standard on January 1, 2019. We are still evaluating the impact that this standard will have on our consolidated financial statements. In March 2016 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. We plan to adopt this standard on January 1, 2017. We are still evaluating the impact that this standard will have on our consolidated financial statements. In May 2014 the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This update outlines a single, comprehensive model for accounting for revenue from contracts with customers. We plan to adopt the standard on January 1, 2018. We are still evaluating the impact that this standard will have on our consolidated financial statements. No other new accounting pronouncements were issued or became effective during the period that had, or are expected to have, a material impact on our consolidated financial statements.
