In April 2010, the FASB issued an accounting update that provides guidance on defining a milestone and determining when it may be appropriate to apply the milestone method of revenue recognition for certain research and development transactions. Under this new standard, a company can recognize as revenue consideration that is contingent upon achievement of a milestone in the period in which it is achieved, only if the milestone meets all criteria to be considered substantive. This standard will be effective for the Company on a prospective basis as of January 1, 2011. The Company is currently evaluating the impact of the adoption of the update. 

In April 2010, the FASB issued an accounting update 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 must not be considered to contain a market, performance, or service condition. Therefore, an entity should not classify such an award as a liability if it otherwise qualifies for classification in equity. This guidance is effective for annual periods beginning on or after December 15, 2010, and will be applied prospectively. Affected entities will be required to record a cumulative catch-up adjustment to the opening balance of retained earnings for all awards outstanding as of the beginning of the annual period in which the guidance is adopted. Earlier application is permitted. The Company is currently evaluating the impact of the adoption of the update. 

In December 2010, the FASB issued an accounting update to require that supplemental pro forma information disclosures pertaining to acquisitions should be presented as if the business combination(s) occurred as of the beginning of the prior annual period when comparative financial statements are presented. This guidance 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. This guidance is effective for business combinations consummated in periods beginning after December 15, 2010. Early adoption is permitted. The Company will make the required disclosures prospectively as of the date of the adoption for any material business combinations or series of immaterial business combinations that are material in the aggregate. The Company does not expect the new accounting standard will have a material impact on the Company financial statements. 

In December 2010, the FASB issued an accounting update to modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. For public entities, this guidance is effective for impairment tests performed during entities’ fiscal years that begin after December 15, 2010. Early application will not be permitted. Based on the Company’s analysis, the Company currently does not anticipate that the new guidance will have a material effect on the Company’s results of operations and financial position or cash flows. 

## b. Share-based compensation 

The Company adopted share-based compensation guidance to recognize compensation cost of options granted by SENAO. The guidance requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service period. The Company has estimated the fair value of stock options as of the date of grant using the Black-Scholes option pricing model. 

The Compensation expenses related to stock options were NT$22 million, NT$17 million and NT$6 million for 2008, 2009 and 2010, respectively. There is no income tax benefit effect related to share-based compensation arrangements.
