Answer:
a. All employees are fully covered by the plan.
Since all the company's employees are covered by the health plan in a similar way, then reimbursements are excluded from gross income. The plan treats all the employees int he same way, so the benefits are the same for everyone, which means that it is company perk and it doesn't discriminate.
b. All employees are covered by the plan. However, only Faldo's executive officers are fully reimbursed for all expenses. All other employees are limited to a maximum reimbursement of $1,000 per year.
Since the health plan discriminates between normal employees and executives, the additional payments made to Nick for being president of the company will be considered as part of his gross income. In this case, the first $1,000 is not included, but the rest, $2,400, must be considered as part of his income.
