Under this plan, participants will receive 1,200 shares of common stock upon election and 1,200 additional shares following each annual meeting of stockholders thereafter. 600,000 shares of Southern Copper common stock have been reserved for this plan. The fair value of the award is measured each year at the date of the grant. The activity of the plan in the six-month period ended June 30, 2011 and 2010 is as follows:

Parent Company common shares: Employee Stock Purchase Plan: In January 2007, the Company offered to eligible employees a stock purchase plan (the “Employee Stock Purchase Plan”) through a trust that acquires shares of Grupo Mexico stock for sale to its employees, employees of subsidiaries, and certain affiliated companies. The purchase price is established at the approximate fair market value on the grant date. Every two years employees will be able to acquire title to 50% of the shares paid for the previous two years. The employees will pay for shares purchased through monthly payroll deductions over the eight year period of the plan. At the end of the eight year period, the Company will grant the participant a bonus of 1 share for every 10 shares purchased by the employee. If Grupo Mexico pays dividends on shares during the eight year period, the participants will be entitled to receive the dividend in cash for all shares that have been fully purchased and paid as of the date that the dividend is paid. If the participant has only partially paid for shares, the entitled dividends will be used to reduce the remaining liability owed for purchased shares. In the case of voluntary resignation of the employee, the Company will pay to the employee the fair market sales price at the date of resignation of the fully paid shares, net of costs and taxes. When the fair market sales value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on the following schedule:
If the resignation occurs during: |  | % Deducted |
1st year after the grant date |  | 90 | %
2nd year after the grant date |  | 80 | %
3rd year after the grant date |  | 70 | %
4th year after the grant date |  | 60 | %
5th year after the grant date |  | 50 | %
6th year after the grant date |  | 40 | %
7th year after the grant date |  | 20 | %
In the case of involuntary termination of the employee, the Company will pay to the employee the fair market sales price at the date of termination of employment of the fully paid shares, net of costs and taxes. When the fair market value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on the following schedule:
If the termination occurs during: |  | % Deducted |
1st year after the grant date |  | 100 | %
2nd year after the grant date |  | 95 | %
3rd year after the grant date |  | 90 | %
4th year after the grant date |  | 80 | %
5th year after the grant date |  | 70 | %
6th year after the grant date |  | 60 | %
7th year after the grant date |  | 50 | %
In case of retirement or death of the employee, the Company will render the buyer or his legal beneficiary, the fair market sales value as of the date of retirement or death of the shares effectively paid, net of costs and taxes.
