Amortization is an important concept in accounting and finance, particularly for intangible assets like patents, trademarks, and goodwill. It helps spread the cost of an asset over its useful life, allowing companies to match the expense with the revenue generated by the asset. For investors, understanding amortization is critical because it affects financial statements, such as the income statement and balance sheet. The process also impacts cash flow and tax calculations, as the amortization expense is deductible.
