serious investors should understand the disparate nature of intangible assets: Some truly deplete over time while others never lose value. With software, for example, amortization charges are very real expenses. Charges against other intangibles such as the amortization of customer relationships, however, arise through purchase-accounting rules and are clearly not real expenses. GAAP accounting draws no distinction between the two types of charges. Both, that is, are recorded as expenses when calculating earnings — even though from an investor’s viewpoint they could not be more different.
