Significant Accounting Policies	2. Significant Accounting Policies *Basis of Presentation* The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”). These interim consolidated financial statements include normal recurring adjustments and the elimination of all intercompany accounts and transactions which are, in the opinion of management, necessary to provide a fair presentation of the Company’s financial condition and results of operations for the periods presented. These interim consolidated financial statements are presented in accordance with ASC 270, “Interim Reporting,” (“ASC 270”) and, accordingly, do not include all of the information and note disclosures required by US GAAP for complete financial statements. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results to be expected for a full year or for any other periods. The December 31, 2012 balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. *Recent Accounting Pronouncements* In February 2013, the FASB issued ASU No.2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” (“ASU 2013-02”) which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, ASU 2013-02 requires an entity to present, either on the face of the income statement or in the notes to financial statements, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The update does not change the current requirements for reporting net income or other comprehensive income in financial statements and is effective prospectively for reporting periods beginning after December 15, 2012. The Company adopted ASU 2013-02 from the quarter ended March 31, 2013. In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. This authoritative guidance was issued to enhance disclosure requirements on offsetting financial assets and liabilities. The new rules require the Company to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position, as well as instruments and transactions subject to a netting arrangement. In January 2013, the FASB further issued ASU No. 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” to address implementation issues surrounding the scope of ASU No. 2011-11 and to clarify the scope of the offsetting disclosures and address any unintended consequences. The Company adopted ASU No.2013-01 from the quarter ended March 31, 2013. In July 2012, the FASB issued ASU No.2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment” (“ASU 2012-02”). Under ASU 2012-02, testing the decline in the realizable value (impairment) of indefinite-lived intangible assets other than goodwill has been simplified. ASU 2012-02 provides the Company the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. The Company electing to perform a qualitative assessment is no longer required to calculate the fair value of an indefinite-lived intangible asset unless the Company determines, based on a qualitative assessment, that it is “more likely than not” that the asset is impaired. ASU 2012-02 is effective for impairment tests for fiscal years beginning after September 15, 2012. The Company adopted ASU 2012-02 from the year ended December 31, 2012, and the adoption does not have a material impact on the Company’s consolidated financial statements. In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350)-Testing Goodwill for Impairment” (“ASU 2011-08”). ASU 2011-08 gives the option to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit. Under the amendments in ASU 2011-08, an entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The amendments in ASU 2011-08 are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2011. Early adoption is permitted. The Company adopted the applicable requirements of ASU 2011-08 in fiscal 2012.
