Debt instrument, convertible, terms of conversion feature |  |  |  |  |  |  |  |  | Holders of the Convertible Notes have the right to convert their Convertible Notes in certain circumstances and during specified periods.

Upon conversion, the Company will pay or deliver, as applicable, cash or a combination of cash (in an amount no less than the principal amount of the Convertible Notes being converted) and common shares, at its election, based on the applicable conversion rates. The initial conversion rate is 34.7766 common shares per $1,000 principal amount of Convertible Notes, which represents an initial conversion price of approximately $28.75 per common share, and is subject to adjustment upon the occurrence of certain events. |  |  |  |  |  |  |  |
