The 2023 Repurchase Right entitles each holder of the Exchangeable Notes to require the Company to repurchase for cash on July 1, 2023 all of such holder’s Exchangeable Notes, or any portion thereof that is equal to US$200,000 or an integral multiple of US$1,000 in excess thereof. The repurchase price for such Exchangeable Notes will be equal to 100% of the principal amount of the Exchangeable Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, July 1, 2023, which is the date specified for repurchase in the Indentures (the “2023 Repurchase Date”), subject to the terms and conditions of the Indentures and the Exchangeable Notes. The 2023 Repurchase Date is an interest payment date under the terms of the Indentures and the Exchangeable Notes. Accordingly, on July 1, 2023, being the interest payment date, the Company will pay accrued and unpaid interest on all of the Exchangeable Notes through June 30, 2023, to all holders who are holders of record at 5:00 p.m., New York City time, on Thursday, June 15, 2023, regardless of whether the 2023 Repurchase Right is exercised with respect to such Exchangeable Notes.

As of May 26, 2023, there was US$500,000,000 in aggregate principal amount of the Exchangeable Notes outstanding. If all outstanding Exchangeable Notes are surrendered for repurchase through exercise of the 2023 Repurchase Right, the aggregate cash purchase price will be US$500,000,000.

The opportunity for holders of the Exchangeable Notes to exercise the 2023 Repurchase Right commences from 9:00 a.m., New York City time, on Friday, May 26, 2023, and will terminate at 5:00 p.m., New York City time, on Thursday, June 29, 2023.
