Final answer:
The actual return on plan assets in 2013 is -$1,146,000.
Step-by-step explanation:
The actual return on plan assets in 2013 can be calculated by subtracting the change in the accumulated benefit obligation (ABO) from the change in the fair value of plan assets. The formula for calculating the change in ABO is: Change in ABO = Projected benefit obligation (PBO) at the end of the year - Accumulated benefit obligation (ABO) at the beginning of the year.
Using the given data, the change in ABO for 2013 is ($4,002,000 - $2,760,000) = $1,242,000. The change in the fair value of plan assets is equal to the contributions made by Turner ($378,000) minus the benefits paid ($282,000), which is $96,000. Therefore, the actual return on plan assets in 2013 is ($96,000 - $1,242,000) = -$1,146,000.
