Step-by-step explanation:
The pension expense for 2013 can be calculated using the formula: Service Cost + Interest on Projected Benefit Obligation - Expected Return On Plan Assets + Amortization of Prior Service Cost.
Plugging in the given numbers, the calculation would be:

- Interest on Projected Benefit Obligation: $54,000
- Interest on Vested Benefits: $24,000
- Amortization of Prior Service Cost due to increase in benefits: $12,000
- Expected Return on Plan Assets: $18,000
Using these values, the pension expense for 2013 would be:
Pension Expense = $92,000 + $54,000 - $18,000 + $12,000 = $140,000
