Accounting Changes and Error Corrections [Abstract]
Impact of New Accounting Standards	12—Impact of New Accounting Standards In May 2014, the Financial Accounting Standards Board (the “FASB”) issued guidance that 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. While this guidance will replace most existing GAAP revenue recognition guidance, the scope of the guidance excludes insurance contracts. The new standard is effective on January 1, 2018. The standard permits the use of either the retrospective or the cumulative effect transition method. Because the accounting for insurance contracts is outside of the scope of the standard, we do not expect the adoption of this guidance to have a significant impact on our financial position, results of operations or cash flows. In January 2016, the FASB issued guidance that generally requires entities to measure equity investments at fair value and recognize changes in fair value in their results of operations. This guidance also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring entities to perform a qualitative assessment to identify impairment. The FASB issued other disclosure and presentation improvements related to financial instruments within the guidance. The guidance is effective for annual and interim reporting periods beginning after December 15, 2017. As a result of this guidance, we will reflect changes in the fair value of our equity investments in our results of operations beginning January 1, 2018. In February 2016, the FASB issued guidance that requires lessees to recognize leases, including operating leases, on the lessee’s balance sheet, unless a lease is considered a short-term lease. This guidance also requires entities to make new judgments to identify leases. The guidance is effective for annual and interim reporting periods beginning after December 15, 2018 and permits early adoption. We do not expect the adoption of this guidance to have a significant impact on our financial position, results of operations or cash flows. In March 2016, the FASB issued guidance that simplifies and improves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for annual and interim reporting periods beginning after December 15, 2016. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows. In June 2016, the FASB issued guidance that amends previous guidance on the impairment of financial instruments by adding an impairment model that requires an entity to recognize expected credit losses as an allowance rather than impairments as credit losses are incurred. The intent of this guidance is to reduce complexity and result in a more timely recognition of expected credit losses. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019. We do not expect the adoption of this guidance to have a significant impact on our financial position, results of operations or cash flows. In March 2017, the FASB issued guidance that amends previous guidance on the amortization period for certain purchased callable debt securities held at a premium. This new guidance shortens the amortization period to the earliest call date. The intent of the new guidance is to align interest income recognition with the expectations incorporated in the market pricing on the underlying securities. The new standard is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted this guidance effective January 1, 2017. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows.
