Recently Issued Accounting Standards	15. Recently Issued Accounting Standards In July 2012, the Financial Accounting Standards Board issued Accounting Standard Update No. 2012-02 “Intangibles—Goodwill and Other (Topic 350)” that amends the accounting guidance on testing indefinite-lived intangible assets for impairment. The amendments in this accounting standard update are intended to reduce complexity and costs by allowing an entity the option to make a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendments also enhance the consistency of impairment testing guidance among long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset’s fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendments in this accounting standard update are effective for interim and annual impairment tests performed for fiscal years beginning after September 15, 2012. The Company tests its indefinite-lived intangible assets for impairment annually in the fourth quarter or more frequently when events or changes in circumstances indicate that impairment may have occurred.
