2. What was the amount of benefit payments distributed to retirees in 2017?
3. Determine the amount of increase (decrease) in the projected benefit obligation (PBO) as a result of amendments to the plan during 2017 and reconcile it to AOCI-prior service costs.
4. Determine the amount of the actuarial loss (gain) on the PBO in 2017.
5. What was the effect of increasing the discount rate from 7.00% in 2016 to 8.25% in 2017?
6. Give the journal entries that Green would have made to record the effects of its pension plan for 2017.
