Intangible assets can bring profit to businesses but their value decreases over time. Amortization is a way to account for this decrease. Three factors affect how intangible assets are amortized: the cost and expense difference, the amortization period, and the method used. It's important to consider the specific costs of different intangible assets and choose a conservative and flexible amortization period. While the straight-line method is commonly used, some assets may benefit from accelerated amortization due to their quick renewal.
