15.  RECENT ACCOUNTING PRONOUNCEMENTS

In April 2010, FASB issued ASU 2010-13 "Compensation-Stock Compensation (Topic 718) Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades" (ASU 2010-13). Topic 718 is amended to clarify that a share-based payment award with an exercise price denominated in the currency of a market in which a substantial portion of the entity's equity securities trades shall not be considered to contain a market, performance, or service condition. Therefore, such an award is not to be classified as a liability if it otherwise qualifies as equity classification. The amendments in this standard are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2010. The guidance should be applied by recording a cumulative-effect adjustment to the opening balance of retained earnings for all outstanding awards as of the beginning of the fiscal year in which the amendments are initially applied. The adoption of the standard did not have a material impact on our consolidated results of operations and financial condition.

In December 2010, FASB issued ASU 2010-28 “Intangibles - Goodwill and Other (Topic 350)” (ASU 2010-28). Topic 350 is amended to clarify the requirement to test for impairment of goodwill. Topic 350 has required that goodwill be tested for impairment if the carrying amount of a reporting unit exceeds its fair value. Under ASU 2010-28, when the carrying amount of a reporting unit is zero or negative an entity must assume that it is more likely than not that a goodwill impairment exists, perform an additional test to determine whether goodwill has been impaired and calculate the amount of that impairment. The modifications to ASC Topic 350 resulting from the issuance of ASU 2010-28 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2010. The adoption of the standard did not have a material impact on our consolidated results of operations and financial condition.

In December 2010, FASB issued ASU 2010-29 “Business Combinations (Topic 805) - Disclosure of Supplementary Pro Forma Information for Business Combinations” (ASU 2010-29). This standard update clarifies that, when presenting comparative financial statements, SEC registrants should disclose revenue and earnings of the combined entity as though the current period business combinations had occurred as of the beginning of the comparable prior annual reporting period only. The update also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. ASU 2010-29 is effective prospectively for material (either on an individual or aggregate basis) business combinations entered into in fiscal years beginning on or after December 15, 2010. The adoption of the standard did not have a material impact on our consolidated financial statements.
 
In June 2011, FASB issued ASU 2011-05, “Comprehensive Income (Topic 220) – Presentation of Comprehensive Income” (ASU 2011-05).  This standard update requires an entity to present 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.  ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of stockholders’ equity.  ASU 2011-05 is effective for the interim and annual periods beginning after December 15, 2011.  We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements as it only requires a change in the format of presentation.

In September 2011, FASB issued ASU 2011-08, “Intangibles-Goodwill and Other (Topic 350) – Testing Goodwill for Impairment”.  ASU 2011-08 provides companies with a new option to determine whether or not it is necessary to apply the traditional two-step quantitative goodwill impairment test in ASC 350, Intangibles – Goodwill and Other.  Under ASU 2011-08 companies are no longer required to calculate the fair value of a reporting unit unless it determines, on the basis of qualitative information, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  ASU 2011-08 is effective for periods ending after December 15, 2011; however, early adoption is permitted for periods ending after September 15, 2011.   We do not anticipate the adoption to have a material impact on our consolidated financial statements.
