Ann: Update - Liability Management and Buy Back, page-3

The liability related to the repurchase of the equity component of the convertible notes has been recorded against equity, with the tax benefit
also recorded against equity. For the repurchase of convertible notes where the repurchase is already settled, the difference between the value
of the consideration attributable to repurchase of the liability component and the repurchase amount (on market) or committed repurchase
amount on the date of the commitment, has been recorded in equity with the tax benefit also recorded in equity.
