In the 36 weeks ended September 8, 2012, as part of our 2007 Long-Term Incentive Plan, we granted a nominal amount of PepsiCo equity performance units (PEPUnits) to certain executive officers. These PEPUnits are earned based on achievement of a cumulative net income performance target and provide an opportunity to earn shares of PepsiCo Common Stock with a value that adjusts based upon absolute changes in PepsiCo’s stock price as well as PepsiCo’s Total Shareholder Return relative to the S&P 500 over a three-year performance period.
