FAIR VALUE | 15. FAIR VALUE (a) Assets and liabilities measured at fair value on a recurring basis In accordance with ASC 820-10, the Group measures financial products, available-for-sale investments, fair value option investment and equity securities with readily determinable fair value at fair value on a recurring basis. Equity securities classified within Level 1 are valued using quoted market prices currently available on the Hong Kong Stock Exchange. Variable-rate financial instruments and available-for-sale investments classified within Level 2 are valued using directly or indirectly observable inputs in the market place. The available-for-sale investments and fair value option investment classified within Level 3 are valued using income approach in discounted cash flow method or market approach in backsolve method. The discounted cash flow analysis and backsolve method require the use of significant unobservable inputs (Level 3 inputs) which involve significant management judgment and estimation. In the valuation of Level 3 financial instruments as of February 28, 2022, the weighted average cost of capital adopted ranges from 19% to 24% with weighted average at 20%, the discount for lack of marketability adopted ranges from 11% to 30% with weighted average at 17%, and the expected volatilities adopted ranges from 40% to 64% with weighted average at 56%. As of February 28, 2021 and 2022, information about inputs for the fair value measurements of the Group’s assets that are measured at fair value on a recurring basis in periods subsequent to their initial recognition is as follows: ​

​ (b) Assets and liabilities measured at fair value on a nonrecurring basis The Group’s goodwill and intangible assets are primarily acquired through business acquisitions. Purchase price allocation are measured at fair value on a nonrecurring basis as of the acquisition dates. The Group measures its goodwill and intangible assets at fair value on a nonrecurring basis annually or whenever events or changes in circumstances indicate that carrying amount of a reporting unit exceeds its fair value. Acquired intangible assets are measured using the income approach - discounted cash flow method when events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. ​ 15. FAIR VALUE - continued (b) Assets and liabilities measured at fair value on a nonrecurring basis - continued The Group measures long-term investments (excluding the equity securities with readily determinable fair values, available-for-sale investments and fair value option investment) at fair value on a nonrecurring basis only if an impairment or observable price adjustment is recognized in the current period. Please see Note 10(2), Note 10(3) and Note 10(4). For equity securities without readily determinable fair values, the fair value was determined using directly or indirectly observable inputs in the market place (Level 2 inputs). Whenever events or changes in circumstances indicate that the carrying value may no longer be recoverable, the fair value of aforementioned long term investments was determined using models with significant unobservable inputs (Level 3 inputs), primarily the management projection of discounted future cash flow and the discount rate.
