Long-Term Investments [Abstract]

Long-Term Investment

The Company treats each equity investment in the consolidated financial statements under the equity method and they are classified as long-term investments, except for the investment in Waferworks which is measured at cost minus impairment, if any, as there is no readily determinable fair value. Under the equity method, an investment is initially recorded at cost, adjusted for any excess of the Company’s share of the incorporated-date fair values of the investee’s identifiable net assets over the cost of the investment (if any). Thereafter, the investment is adjusted for the post incorporation change in the Company’s share of the investee’s net assets and any impairment loss relating to the investment. The Company concluded

that the investments were not impaired and did not record any impairment charges related to the investments for any prior periods.
