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 collateral when recognizing derivative assets and liabilities.

It permits an entity to first assess qualitative factors to determine whether further testing for impairment of indefinite-lived intangible assets other than goodwill is required. 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).

Additional information regarding derivative offsetting is provided in Note 7 (“Derivatives and Hedging Activities”).
