Answer:
1. Defined Benefit Plan
2. debit Vacation Pay Expense; credit Vacation Pay Payable
Explanation:
1. With a Defined Benefit Plan, employers promise to pay employees a pension based on factors like years of service and salary. The plan will be sponsored by the employer and will be managed by the company.
2. As the Vacation is an expense, it will need to be debited to an expense account being the Vacation Pay Expense account. It will also be credited to the Vacation Pay Payable to reflect that this is a liability that the company must fulfil.
