Answer:
$31,500
Step-by-step explanation:
For the year ended December 31, 2005, Gavin should report vacation pay expense of $31,500
The total vacation pay expense for 2005 is $31,500 which is the sum of two amounts:
1. the amount earned in 2005, plus
2. the increase in cost from earlier periods owing to wage increases in 2005.
These two amounts are:(1) $30,000 as given in the problem - this amount is already updated for the most current rate
(2) $1,500 = ($35,000 - $20,000).10 = the amount of vacation pay yet to be disbursed on benefits earned before 2005; the liability for this amount is increased by the 10% pay increase.
The increase in pay rate on the pre-2005 benefits is treated as an estimate change. Therefore, it is handled in current and future years.
Retroactive application does not apply in this case.
