Answer: d. As the company will ultimately get 100% of the deduction, no contingency reserve is required.
Explanation:
Just because the company will eventually get 100% of the deduction does not mean that no contingency reserve is required.
A contingency reserve needs to be created that is the same amount as the deferred tax asset which arises from the claimed deduction and deducted from every year to offset the deduction for that particular year until the 5 years have elapsed.
