In October 2017, the Company issued US$900 million in aggregate principal amount of 1.25% coupon interest convertible senior notes due on November 15, 2022 (“2022 Notes”) at par.

The conversion rate may be adjusted under certain circumstances, such as distribution of dividends and stock splits. In addition, upon a make-whole fundamental change prior to the maturity date of the notes, the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert his/her notes in connection with such make-whole fundamental change.
