2. Accounting Changes: In May 2011, the Financial Accounting Standards Board (FASB) issued amended guidance and disclosure requirements for fair value measurements. These amendments did not have a material impact on the consolidated financial results. These changes became effective January 1, 2012 on a prospective basis. See Note 3, “Financial Instruments” on pages 9 to 14 for fair value disclosures.

In July 2012, the FASB issued amended guidance that simplifies how entities test indefinite-lived intangible assets other than goodwill for impairment.  After an assessment of certain qualitative factors, if it is determined to be more likely than not that an indefinite-lived asset is impaired, entities must perform the quantitative impairment test.  Otherwise, the quantitative test is optional.  The amended guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted.  The adoption of this guidance is not expected to have a material impact on the company’s financial results.
