Accounting Changes and Error Corrections [Abstract]
New accounting standards	New accounting standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In July 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date. This guidance approves a one-year deferral of the effective date of ASU 2014-09. The ASU now permits the Company to adopt this standard effective January 1, 2018. Early application is permitted as of January 1, 2017. In March, April, and May 2016, the FASB issued ASU 2016-08, ASU 2016-10, ASU 2016-11, and ASU 2016-12, Revenue from Contracts with Customers (Topic 606), each of which amends the guidance in ASU 2014-09. When they become effective, these ASUs will replace most existing revenue recognition guidance in GAAP. The Company has assembled an internal revenue task force that meets regularly to discuss and evaluate the overall impact this guidance will have on various revenue streams in the condensed consolidated financial statements and related disclosures. The Company is continuing to evaluate the impact this guidance will have on its consolidated financial statements. The Company expects to adopt these ASU’s effective January 1, 2018 retrospectively with the cumulative effect of initially applying it recognized at the date of initial application (the cumulative effect method). In January 2016, the FASB issued ASU No. 2016-01, Financial Statements - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU revise accounting related to (i) the classification and measurement of investments in equity securities and (ii) the presentation of certain fair value changes for financial liabilities at fair value. The amendments in this ASU are effective for the Company beginning on January 1, 2018 and are to be applied through a cumulative effect adjustment to the statement of financial position. Early adoption is permitted under certain circumstances. The adoption of this ASU is not expected to have a material impact on the Company’s condensed consolidated financial statements when adopted on January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for substantially all leases with lease terms in excess of twelve months. The new lease guidance also simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The amendments in this ASU are effective for the Company beginning on January 1, 2019 and are to be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. The Company has assembled an internal lease task force that meets regularly to discuss and evaluate the overall impact of this guidance on its condensed consolidated financial statements and related disclosures, as well as the expected timing of adoption. The Company believes that the new standard will have a material impact on its condensed consolidated balance sheet but will not have a material impact on its results of operations or liquidity. The Company expects to adopt this ASU on January 1, 2019, and continues to evaluate the effect that the implementation of this ASU will have on its condensed consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amendments in this ASU eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments in this ASU were effective for the Company beginning on January 1, 2017 and was applied prospectively. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The changes required by this ASU involve several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and an election on estimating forfeitures. The amendments in this ASU were effective for the Company beginning January 1, 2017. The method of adoption differs for each of the topics covered by the ASU. The primary effect of this ASU for the Company is the presentation of excess tax benefits or deficiencies as a component of income tax expense within the Company's condensed consolidated statement of income rather than within additional paid-in capital on its condensed consolidated balance sheet. In addition, these excess tax benefits or deficiencies are presented as an operating activity on the condensed consolidated statement of cash flows rather than as a financing activity. The Company elected to apply the presentation requirements for cash flows related to excess tax benefits prospectively. Additionally, the Company has elected to continue to estimate forfeitures expected to occur in determining the amount of compensation cost to be recognized each period. The new standard may cause volatility in the Company’s effective tax rates and diluted earnings per share due to the tax effects related to share-based payments being recorded within the Company’s condensed consolidated statement of income, including a potential increase in the Company’s provision for income taxes if a significant number of outstanding stock awards are exercised at recent levels of the Company’s stock price. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this ASU clarify how certain cash receipts and cash payments should be classified on the statement of cash flows. The new standard is effective for the Company beginning January 1, 2018 and should be applied retrospectively to all periods presented. The Company has not yet determined the effect that adoption of this ASU will have on its condensed consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The amendments in this ASU allow entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The current guidance does not allow recognition until the asset has been sold to an outside party. The amendments in this ASU are effective for the Company beginning on January 1, 2018 and are to be applied on a modified retrospective basis. The Company has not yet determined the effect that adoption of this ASU will have on its condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this ASU simplify the test for goodwill impairment by eliminating the second step in testing for goodwill impairment. The amendments in this new ASU are effective for the Company January 1, 2020 and are to be applied on a prospective basis. Early adoption is permitted after January 1, 2017. The Company early adopted this ASU as of January 1, 2017.
