The guideline for your first year grant will be $1,500,000, subject to the provisions of the plan at the time of grant. As a reference, in 2012, 80% of equity was granted as performance-based restricted stock units and 20% was granted as stock options. The design of the program is reviewed each year and is subject to change.

• You will receive a special one-time sign-on cash bonus of $1,500,000, less any applicable tax withholding, payable as soon as administratively feasible after your start date. Should you voluntarily terminate your employment with Alcoa for any reason within three years of receipt of this payment you agree to reimburse Alcoa pro-rata for the time after your date of termination not worked within three years of hire.
