Accounting Policies	3. Accounting Policies Newly Issued Accounting Standards In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, Fair Value Measurement — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”). The amendments result in common fair value measurement and disclosure requirements in U.S. GAAP and international financial reporting standards (“IFRS”). To improve consistency in application across jurisdictions, some wording changes are necessary to ensure that U.S. GAAP and IFRS fair value measurement and disclosure requirements are described in the same way. ASU 2011-04 also provides for certain changes in current U.S. GAAP disclosure requirements. The amendments in ASU 2011-04 are to be applied prospectively, and will be effective for the Company’s fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-04 is not expected to have a material impact on the Company’s consolidated balance sheets, statements of income or statements of cash flows. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income — Presentation of Comprehensive Income (“ASU 2011-05”). ASU 2011-05 will require the presentation of the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income, nor does it affect how earnings per share is calculated or presented. Current U.S. GAAP allows reporting entities three alternatives for presenting other comprehensive income and its components in financial statements. One of those presentation options is to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity, which is the presentation format the Company currently uses. This update eliminates that option. The changes to the presentation format are required to be applied retrospectively, and will be effective for the Company’s fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 is not expected to have a material impact on the Company’s consolidated balance sheets, statements of income or statements of cash flows. In September 2011, the FASB issued ASU No. 2011-08, Intangibles-Goodwill and Other — Testing Goodwill for Impairment ("ASU 2011-08"). The amendments in ASU No. 2011-08 are intended to simplify goodwill impairment testing by adding a qualitative review step to assess whether the required quantitative impairment analysis that exists today is necessary. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on the qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. ASU No. 2011-08 will be effective for the Company's fiscal years beginning after December 15, 2011; earlier adoption is permitted. As the amendments do not change the underlying principle that the carrying value of goodwill should not exceed its implied fair value, the adoption of ASU 2011-08 is not expected to have a material impact on the Company’s consolidated balance sheets, statements of income or statements of cash flows. The Company reviewed all other significant newly issued accounting pronouncements and concluded that they either are not applicable to the Company’s operations or that no material effect is expected on the consolidated financial statements as a result of future adoption.
