Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	Accounting Updates Adopted in 2013: Accounting Standards Codification (ASC) 210 "Balance Sheet - Disclosures about Offsetting Assets and Liabilities" In December 2011, the Financial Accounting Standards Board (FASB) issued an update requiring additional disclosures and information about financial instruments and derivative instruments that are either offset on the balance sheet or are subject to an enforceable master netting arrangement. These disclosures provide information about the effect or potential effect of netting arrangements on an entity's financial position, including the effect or potential effect of rights of set-off associated with certain financial instruments and derivative instruments. In January 2013, the FASB issued an update to clarify the scope of transactions that are subject to the disclosures about offsetting. Specifically, the update applies only to derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions to the extent they are subject to a master netting arrangement or similar agreement. We adopted these updates effective January 1, 2013. The adoption of these updates expanded our disclosures but had no effect on our financial position or results of operations. ASC 220 "Comprehensive Income" In February 2013, the FASB issued an update to improve the transparency of reporting reclassifications out of accumulated other comprehensive income by requiring additional information to be presented regarding certain reclassification adjustments. We adopted this update effective January 1, 2013. The adoption of this update expanded our disclosures but had no effect on our financial position or results of operations. ASC 815 "Derivatives and Hedging" In July 2013, the FASB issued an update which allows entities to use the Fed Funds Effective Swap Rate, also referred to as the Overnight Index Swap Rate (OIS), as a benchmark interest rate for hedge accounting purposes. Previously the only acceptable benchmark rates for hedge accounting purposes under GAAP were U.S. Treasury rates and the London Interbank Offered Rate (LIBOR) swap rate. This update reflects the evolution of market hedging practices and is intended to provide more flexibility in hedging interest rate risk. We adopted this update effective July 17, 2013 for qualifying new or redesignated hedging relationships entered into on or after that date. Accounting Updates Adopted in 2012: ASC 220 "Comprehensive Income" In June 2011, the FASB issued an update related to the financial statement presentation of comprehensive income. This update requires that non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present net income and its components, followed consecutively by a second statement presenting total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. We adopted this update effective January 1, 2012. The adoption of this update modified our financial statement presentation but had no effect on our financial position or results of operations. ASC 350 "Intangibles - Goodwill and Other" In September 2011, the FASB issued an update which gives companies the option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. We adopted this update effective January 1, 2012. The adoption of this update had no effect on our financial position or results of operations. ASC 820 "Fair Value Measurements and Disclosures" In May 2011, the FASB issued an update to require additional disclosures regarding fair value measurements and to provide clarifying guidance on the application of existing fair value measurement requirements. Specifically, the update requires additional information on Level 1 and Level 2 transfers within the fair value hierarchy; the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial position, but for which the fair value of such items is required to be disclosed; and information about the sensitivity of a fair value measurement in Level 3 of the fair value hierarchy to changes in unobservable inputs and any interrelationships between those unobservable inputs. We adopted this update effective January 1, 2012. The adoption of this update expanded our disclosures but had no effect on our financial position or results of operations. ASC 860 "Transfers and Servicing" In April 2011, the FASB issued an update to revise the criteria for assessing effective control for repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. The determination of whether the transfer of a financial asset subject to a repurchase agreement is a sale is based, in part, on whether the entity maintains effective control over the financial asset. This update removes from the assessment of effective control the criterion requiring the transferor to have the ability to repurchase or redeem the financial asset on substantially the agreed terms, even in the event of default by the transferee, and the related requirement to demonstrate that the transferor possess adequate collateral to fund substantially all the cost of purchasing replacement financial assets. We adopted this update effective January 1, 2012. The adoption of this update had no effect on our financial position or results of operations. ASC 944 "Financial Services - Insurance" In October 2010, the FASB issued an update to address the diversity in practice regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify as deferred acquisition costs. The amendments in the update require that only incremental direct costs associated with the successful acquisition of a new or renewal insurance contract can be capitalized. All other costs are to be expensed as incurred. We adopted this update effective January 1, 2012 and applied the amendments retrospectively, adjusting all prior periods in our consolidated financial statements and accompanying notes. Accounting Updates Adopted in 2011: ASC 310 "Receivables" In April 2011, the FASB issued an update to provide additional clarification to help creditors in determining whether a creditor has granted a concession as well as whether a debtor is experiencing financial difficulties for purposes of determining whether a restructuring constitutes a troubled debt restructuring. We adopted this update effective July 1, 2011. The adoption of this update expanded our disclosures but had no effect on our financial position or results of operations. Accounting Updates Outstanding: ASC 323 "Investments - Equity Method and Joint Ventures" In January 2014, the 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 amendments in the update permit 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 by the update. The amendments in the update are effective for interim and annual periods beginning on or after December 15, 2014, with early adoption permitted, and are to be applied retrospectively. We have not yet finalized the expected impact on our financial position or results of operations.
