[1] The Company's 0.625% Senior Convertible Notes due 2033 (the "2033 Notes") are not included in the table above. The par amount of convertible notes is payable in cash equal to the principal amount of the notes plus any accrued and unpaid interest and then the "in-the-money" conversion benefit feature at the conversion price above $18.83 per share is payable in cash, shares of the Company's common stock or a combination of both. Refer to "Note 10. Debts and Letters of Credit" for more details.

[2] As the Company incurred a net loss in the period, potential dilutive securities from employee stock options, employee stock purchase plan ("ESPP") and restricted stock units ("RSUs") have been excluded from the diluted net loss per share computations as their effects were deemed anti-dilutive.
