(e) 2018 Performance Bonus Plan

On January 11, 2018, the Compensation Committee approved our 2018 performance bonus program for our named executive officers. The 2018 annual performance bonuses for each named executive officer (as set forth in our proxy statement for our Annual Meeting of Stockholders held on June 9, 2017), other than Dr. Susan Molineaux, will be based upon the achievement of corporate performance goals (80%) and individual performance goals (20%). Dr. Susan Molineaux’s annual performance bonus will be based solely upon the achievement of corporate performance goals. The corporate performance goals relate to the advancement of our clinical trials, business and corporate development objectives, collaboration objectives and financial management objectives. The individual performance goals will consist of a subjective assessment of each named executive officer’s individual contributions to Calithera. The following table sets forth the base salary and target bonuses for 2018:
