But here's the rub. The market doesn't pay that much if any attention to goodwill amortization expenses anyway. The first reason has to do with the fact that they're non-cash expenses. If it denotes an expense that will not recur, then it has little meaning. But where it does have meaning is where the expense will recur.
Some people treat depreciation as an expense that can be ignored because it's a non-cash expense.
Do this at your own risk. Depreciation is a memorandum denoting the consumption of an asset that will most likely need to be replaced. That replacement cost will be paid in cash. If one can't tell how much resources have been invested to create a dollar of earnings, one cannot get a good idea of how much resources it will take in the future to create another dollar of earnings. Without that information, it can be difficult to know the real quality of today's earnings and how much the company can grow in the future.
