Answer: $50000
Explanation:
From the question, we are informed that Sheller Company estimates that its pension plan asset will earn a return of 10% as the beginning balance of plan assets was $500,000 and the ending balance was $560,000.
Due to this, then the pension expense will decrease by:
= 10% × $500,000
= $50,000
It should be noted that the expected return on plan assets will reduce pension expense by $50000.
