Goodwill is an intangible asset that occurs when a company buys another business for more than the value of its identifiable assets, reflecting the extra value from things like reputation and customer relationships.
For example, a buyer pays $1.8 million to acquire a plumbing company whose identifiable assets — trucks, tools, and receivables — are valued at $1.2 million. The $600,000 difference is recorded as goodwill on the buyer's balance sheet, representing the value of the seller's loyal customer base and brand reputation.
Why it matters: It accounts for intangible value like brand reputation; however, if the acquired business underperforms, goodwill must be written down, crushing net income.
