Offsetting Derivative Positions	Offsetting Derivative Positions In accordance with the applicable accounting guidance, we take into account the impact of bilateral collateral and master netting agreements that allow us to settle all derivative contracts held with a single counterparty on a net basis, and to offset the net derivative position with the related cash collateral when recognizing derivative assets and liabilities. Additional information regarding derivative offsetting is provided in Note 7 (“Derivatives and Hedging Activities”).
Benchmark Interest Rate	*Benchmark interest rate.* In July 2013, the FASB issued new accounting guidance allowing entities to designate the Federal Funds Effective Swap Rate (which is the Overnight Index Swap rate, or OIS rate, in the U.S.) as a benchmark interest rate, in addition to U.S. Treasury and LIBOR rates, for hedge accounting purposes. This new accounting guidance was effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013 (effective July 17, 2013, for us). Note 7 (“Derivatives and Hedging Activities”) provides information regarding our use of derivatives and hedge accounting.
Reporting of Amounts Reclassified Out of AOCI	*Reporting of amounts reclassified out of AOCI.* In February 2013, the FASB issued new accounting guidance that requires reclassifications of amounts out of AOCI to be reported in a new format. It does not require the reporting of any information that is not currently required to be disclosed under existing GAAP. This accounting guidance was effective prospectively for reporting periods beginning after December 15, 2012 (effective January 1, 2013, for us). The disclosures required by this accounting guidance are provided in Note 16 (“Accumulated Other Comprehensive Income”).

This accounting guidance was effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 (January 1, 2013, for us). The adoption of this accounting guidance did not have a material effect on our financial condition or results of operations.

This accounting guidance was effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods (effective January 1, 2013, for us). Information about our offsetting and related arrangements is provided in Note 12 (“Securities Financing Activities”).

This accounting guidance will be applied prospectively to unrecognized tax benefits that exist at the effective date. It will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (effective January 1, 2014, for us). Early adoption and/or retrospective application are permitted. The adoption of this accounting guidance is not expected to have a material effect on our financial condition or results of operations.
Investment Companies	*Investment companies.* In June 2013, the FASB issued new accounting guidance that modifies the criteria used in defining an investment company. It also sets forth certain measurement and disclosure requirements for an investment company. This accounting guidance will be effective for interim and annual reporting periods in fiscal years that begin after December 15, 2013 (effective January 1, 2014, for us). Early application is prohibited. We are currently evaluating the impact this accounting guidance may have on our financial condition or results of operations.
Liquidation Basis of Accounting	*Liquidation basis of accounting.* In April 2013, the FASB issued new accounting guidance that specifies when and how an entity should prepare its financial statements using the liquidation basis of accounting when liquidation is imminent as defined in the guidance and describes the related disclosures that should be made. This new accounting guidance will be effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein (effective January 1, 2014, for us). Entities should apply the requirements prospectively from the day that liquidation becomes imminent. Early adoption is permitted.
Reporting of Cumulative Translation Adjustments upon the Derecognition of Certain Investments	*Reporting of cumulative translation adjustments upon the derecognition of certain investments.* In March 2013, the FASB issued new accounting guidance that addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. This accounting guidance will be effective prospectively for reporting periods beginning after December 15, 2013 (effective January 1, 2014, for us). The adoption of this accounting guidance is not expected to have a material effect on our financial condition or results of operations.
