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!). Athletes and vegetarians are special populations that may require supplements.
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.
The software automatically calculated the amortization period as 2.82 years because the payment was specified.. The 2.82 years is 33 payments of $350 plus a 34th payment of $285.57 The 34th and last payment of 285.57 is because of the mathematics. You cannot always specify an exact payment to the end of the amortization period. The last payment sometimes is less than the prior payments in order to have the equations balance.
