Effective January 1, 2013, we adopted ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amended standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Derivative instruments (see Note 9), which are subject to master netting arrangements, are not considered material and are excluded from the below disclosures.
