Final Answer:
The convention that applies to the amortization of purchased intangibles is the Mid-Month Convention. Option C is answer.
Step-by-step explanation:
The Mid-Month Convention is a method used for the amortization of purchased intangibles, allocating the expense over the asset's useful life. This convention assumes that the asset is placed in service or disposed of at the midpoint of the month, regardless of the actual acquisition date. It is a practical approach for accounting purposes to evenly distribute amortization expenses.
Options (a) Half-Year Convention and (b) Mid-Quarter Convention are conventions applied to tangible property, not specifically to intangibles. Option (d) No specific convention applies to intangibles amortization is incorrect because there is a specific convention, which is the Mid-Month Convention, commonly used in accounting practices for intangible assets.
Option C (Mid-Month Convention) is the answer.
