Answer: c. Sydney can diversify 50% of her WillCo stock.
Explanation:
Employee stock ownership plan (ESOP) is simply referred to as an employee benefit where the employees of a particular company are given ownership interest as long as some certain criteria are met.
Once the workers become qualified participants, they can diversify certain percentage of their stocks. From the 1st-5th year, a qualified participant is allowed to diversify about 25% of his or her stock account and about 50% in the 6th year.
Based on the explanation, since Sydney has worked for WillCo for the last 20 years, Sydney can diversify 50% of her WillCo stock.
