Answer:
Havana's 2016 actual return on plan asset is $504 thousand.
Explanation:
Havana's 2016 actual return on plan asset is $504 thousand.
Let actual return be x.
Ending balance of plan assets = Beginning balance of plan asset + Actual return + Cash Contributions - Retiree benefits
$6,336 = $5,760 + x + $696 - $624
x = $6,336 - $5,760 - $696 + $624
x= $504 (answer).
