Equity investments whereby we have significant influence but not control over the investee, and are not the primary beneficiary of the investee’s activities, are accounted for under the equity method. Under this method, we record our share of gains or losses attributable to equity method investments.

Non-marketable equity securities consist of investments in privately held companies without readily determinable fair values, and are reported at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. We estimate the fair value of our equity investments using Level 3 inputs to assess whether impairment losses shall be recorded.
