How much will you receive at expiry?
You are not required to deliver any exercise notice and the Warrants will be automatically exercised on the
relevant Expiry Date. You will receive a Cash Settlement Amount (if positive) in Hong Kong dollars calculated as
follows:
Cash Settlement Amount per Exercise Amount = Entitlement x (Closing Price – Exercise Price) – Exercise Expenses
“Closing Price” means the arithmetic mean of the closing prices of one Share (as derived from the Daily
Quotation Sheet of the Stock Exchange) for each of the five business days immediately preceding the Expiry Date,
subject to adjustment in accordance with the terms and conditions of the Warrants.
“Exercise Expenses” mean any charges or expenses including any taxes or duties which are incurred in respect
of the exercise of the Warrants.
