New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements Policy	Accounting Updates Outstanding: Accounting Standards Codification (ASC) 323 "Investments - Equity Method and Joint Ventures" In January 2014, the Financial Accounting Standards Board (FASB) issued an update to provide guidance on the accounting and reporting for investments in affordable housing projects that qualify for low-income housing tax credits. The guidance permits entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Additional disclosures concerning investments in qualified affordable housing projects will also be required. The guidance is effective for interim and annual periods beginning on or after December 15, 2014, with early adoption permitted, and is to be applied retrospectively. We have not yet finalized the effect on our financial position or results of operations. We will adopt this update effective January 1, 2015. ASC 606 "Revenue from Contracts with Customers" In May 2014, the FASB issued an update that will supersede virtually all existing guidance regarding the recognition of revenue from customers. Specifically excluded from the scope of this update are insurance contracts, although our fee-based service products are included within the scope. The issuance of the new guidance completes the joint effort by the FASB and the International Accounting Standards Board to develop a common revenue standard for GAAP and International Financial Reporting Standards. The guidance is intended to improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets and provide more useful information through improved disclosure requirements. The core principal of this guidance is that revenue recognition should depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The guidance is effective for interim and annual periods beginning after December 15, 2016 and is to be applied retrospectively. The adoption of this update will not have a material effect on our financial position or results of operations. ASC 718 "Compensation - Stock Compensation" In June 2014, the FASB issued an update to clarify that a performance target that affects vesting of a share-based payment and can be achieved after the requisite service is to be treated as a performance condition and should not be reflected in the determination of the grant date fair value of the award. Compensation cost for such an award should be recognized over the required service period when the achievement of the performance condition becomes probable. The guidance is intended to address diversity in practice and is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted, and may be applied either prospectively or retrospectively. The adoption of this update will not have a material effect on our financial position or results of operations. We will adopt this update effective January 1, 2016. ASC 860 "Transfers and Servicing" In June 2014, the FASB issued an update to change the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The update also requires disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions. The guidance is effective for interim and annual periods beginning after December 15, 2014, with the exception of certain of the additional disclosures, which will be effective for annual periods beginning after December 15, 2014 and for interim periods beginning after March 15, 2015. The guidance is to be applied retrospectively for transactions outstanding on the effective date of the update. The adoption of this update will expand our disclosures but is expected to have no effect on our financial position or results of operations.
