| Impact of Accounting Changes                            | IMPACT OF ACCOUNTING CHANGESFASB Accounting Standards Update No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis The FASB has issued an Accounting Standards Update (ASU) No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions).  The ASU focuses on the consolidation evaluation for reporting organizations (public and private companies and not-for-profit organizations) that are required to evaluate whether they should consolidate certain legal entities.  In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ (Codification) and improves current GAAP by:•Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met.•Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE).•Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.The ASU will be effective for periods beginning after December 15, 2015, for public companies. For private companies and not-for-profit organizations, the ASU will be effective for annual periods beginning after December 15, 2016; and for interim periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period.  Adoption of this ASU is not expected to have a significant effect on the Corporation’s consolidated financial statements. |
