In connection with the offering, the Company entered into a convertible note hedge transaction with an affiliate of one of the initial purchasers (the "hedge counterparty") and a warrant transaction with the hedge counterparty at a higher strike price. The convertible note hedge transaction is expected generally to offset potential dilution to the ordinary shares and ADSs upon any conversion of notes. However, the warrant transaction could separately have a dilutive effect to the extent that the market value per ADS exceeds the applicable strike price of the warrants subject to the Company's ability to elect cash settlement of the warrants under certain circumstances. If the over-allotment option is exercised, the Company may enter into additional note hedge and warrant transactions with the hedge counterparty.The Company has been advised that, in connection with establishing its initial hedge of the convertible note hedge transaction and warrant transaction, the hedge counterparty and/or its affiliates expect to enter into various derivative transactions with respect to the ADSs and/or to purchase ADSs concurrently with, or shortly after, the pricing of the notes. This activity could have the effect of increasing or preventing a decline in the price of the ADSs concurrently with, or shortly after, the pricing of the notes. In addition, the hedge counterparty and/or its affiliates may modify their hedge positions by unwinding these derivative transactions, entering into or unwinding additional derivative transactions with respect to the ADSs and/or purchasing or selling the ADSs or other securities of the Company in secondary market transactions from time to time following the pricing of the notes and prior to the maturity of the notes (and are likely to do so following any conversion of the notes, upon any early termination or early exercise of the convertible note hedge and warrant transactions, and during a 20-trading-day period beginning on, and including, the maturity date of the notes).
