2020 Executive Salaries

On February 18, 2020, the Compensation Committee of the Board of Directors (the “Committee”) of Diodes Incorporated (the “Company”) established the base salaries of certain executive officers effective February 19, 2020 as follows:

2020 Long-term Incentive (LTI)

On February 18, 2020, the Committee also granted long-term incentive (“LTI”) awards under the Company’s previously disclosed LTI plan to certain executive officers for services to be rendered in fiscal 2020.

Each LTI award consists of (1) restricted stock units (“RSUs”) which vest ratably over four years (i.e., 25% on each anniversary of the award) and (2) performance stock units (“PSUs”) which contain a performance vesting condition by which the PSUs will vest upon the Company achieving a cumulative 3-year non-GAAP operating income target of $390.6 million.

If the Company achieves the Company-wide performance target, the executive will be entitled to receive 100% of their PSUs. Achievement of 80% of the performance target (the “threshold”) would result in the vesting of 50% of the target PSUs, and achievement of 120% of the performance target (the “maximum”) would result in the vesting of 200% of the target PSUs. Achievement of less than 80% of the performance target would result in the vesting of no PSUs, and achievement of above 120% of the performance target would not result in the vesting of more than 200% of the target PSUs. Achievement of between the threshold and the target, and between the target and the maximum, would result in the vesting of a prorated number of PSUs.

The table below sets forth the number of RSUs and the target PSUs awarded to the following executive officers:
