Accounting Changes and Error Corrections [Abstract]
New accounting pronouncements	In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 applies to contracts with customers, excluding, most notably, insurance and leasing contracts. ASU 2014-09 prescribes a framework in accounting for revenues from contracts within its scope, including (a) identification of the contract, (b) identification of the performance obligations under the contract, (c) determination of the transaction price, (d) allocation of the transaction price to the identified performance obligations and (e) recognition of revenues as the identified performance obligations are satisfied. ASU 2014-09 also prescribes additional disclosures and financial statement presentations. On July 9, 2015, the FASB deferred the effective date of ASU 2014-09 to reporting periods beginning after December 15, 2017. Early adoption is permitted for reporting periods beginning after December 15, 2016. ASU 2014-09 may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. In April 2015, the FASB issued ASU 2015-05 “Intangibles—Goodwill and Other—Internal-Use Software,” which clarifies that software licenses contained in a cloud computing arrangement should be capitalized if the customer has the right to take possession of the software and the ability to run the software outside of the cloud computing arrangement. ASU 2015-05 is effective for annual periods beginning after December 15, 2015 and may be adopted prospectively or retrospectively. Early adoption is permitted. In April 2015, the FASB also issued ASU 2015-03 “Interest—Imputation of Interest,” which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, instead of as an asset. The recognition and measurement guidance for debt issuance costs under current GAAP is not affected by ASU 2015-03. ASU 2015-03 is effective for reporting periods beginning after December 15, 2015 and should be adopted retrospectively. Early adoption is permitted for financial statements that have not been previously issued. In May 2015, the FASB issued ASU 2015-09 “Financial Services—Insurance—Disclosures about Short-Duration Contracts,” which requires additional disclosures in annual and interim reporting periods by insurance entities regarding liabilities for unpaid claims and claim adjustment expenses, and any changes in assumptions or methodologies for calculations of such liabilities. ASU 2015-09 is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. Early adoption is permitted. We are evaluating the effect the adoption each of these standards will have on our Consolidated Financial Statements.
