What Is Goodwill?
Goodwill is the premium an acquirer pays above the fair market value of a target company's identifiable assets minus its liabilities. It only appears on the balance sheet as a result of an acquisition; a company cannot create goodwill through its own operations.
Conceptually, goodwill represents the value of things that are real but hard to itemize, such as reputation, workforce quality, customer loyalty, and anticipated synergies from combining two businesses.
How It Works
In purchase accounting, the acquirer allocates the purchase price to the target's tangible assets and identifiable intangible assets at fair value, and whatever is left over becomes goodwill. The formula is Goodwill = Purchase Price - Fair Value of Identifiable Net Assets.
Under both US GAAP and IFRS, goodwill is not amortized for public companies. Instead it is tested for impairment at least annually, and if the acquired business underperforms, the company must write goodwill down and take a charge through the income statement.
Example
Suppose an acquirer pays $500 million for a company whose identifiable assets are valued at $600 million and whose liabilities total $250 million. The fair value of identifiable net assets is $350 million, so the acquirer records $500 million - $350 million = $150 million of goodwill on its balance sheet.
Why It Matters
Large goodwill balances tell you a company has grown through acquisitions and paid meaningful premiums to do so. Big impairment charges, like those that have followed overpriced megadeals, are effectively an admission that the acquirer overpaid.
Goodwill is a staple of investment banking interviews: M&A technical questions frequently ask you to calculate goodwill in a deal and explain how a goodwill impairment flows through the three financial statements.
