Final answer:
Based on the new estimate, the company must reassess its decision about the options issued to the executive and potentially fulfill the contingent requirement if the target is met.
Step-by-step explanation:

Since the target is now deemed achievable, the company may need to revalue the options and potentially fulfill the contingent requirement if the target is met.
