If market conditions are favorable, the forward contracts will be exercised with a charge to the share repurchase reserve approved by the Shareholders' Meeting, in accordance with the Policy for the Acquisition and Disposition of Own Shares approved by the Board of Directors.

As of September 30, 2012, the fair value for not exercising the contracts was the equivalent to a loss of Ps. 31 million in financial derivative effects.
