At the beginning of the fiscal year, David Company purchased for $1,030,000 a patent that applies to the manufacture of a unique tamper-proof lid for medicine bottles. David incurred legal costs of $450,000 in successfully defending use of the lid by a competitor. David estimated that the patent would be valuable for at least ten years.
During the first two years of operations, David successfully marketed the lid. At the beginning of the third year, a study appeared in a consumer magazine showing that children could in fact remove the lid. As a result, all orders for the lids were canceled, and the patent was rendered worthless.
Prepare journal entries to record the following:
