I was wondering if you would be able to help me with this problem

Earnest, Inc. holds a patent (#54321-BO) on an advanced form of political hooey. Earnest does not manufacture or sell the hooey, rather it licenses the patent to various administrations on a royalty basis. From time to time it may sell one of its patents. The history of patent#54321-BO is as follows: Cost Incurred

Amortization is computed for an entire year if the cost is incurred before July 1st, and no amortization is recorded if the cost is incurred after June 30th.
