If you are an active person, chances are you do not need a protein supplement and using one will be counterproductive because of the extra calories (remember, 1 gram of protein provides as many kilocalories as 1 gram of sugar!).

Amortization expense is a non-cash expense. Therefore, like all non-cash expenses, it will be added to the net income when drafting an indirect cash flow statement. The same applies to depreciation of physical assets, as well other non-cash expenditures, such as increases in payables and accumulated interest expenses.
Amortization in accounting. When a company amortizes an asset, it is spreading out the cost of that asset over the course of its useful life. Amortization roughly matches the expense of an asset with the revenue it brings in. As a business writes off an asset, that asset is shifted from the balance sheet to the income statement. Amortization is used to write off intangible assets that have a specific useful life.
