In accounting, goodwill is an intangible value attached to a company resulting mainly from the company’s management skill or know-how and a favorable reputation with customers. A company’s value may be greater than the total of the fair market value of its tangible and identifiable intangible assets. This greater value means that the company generates an above-average income on each dollar invested in the business. Thus, proof of a company’s goodwill is its ability to generate superior earnings or income.
