Tangible Book Value

Tangible book value strips goodwill and intangible assets out of shareholders' equity, leaving the net worth backed by assets you could point at: cash, securities, receivables, inventory, property. The logic is conservative — goodwill is the premium paid in past acquisitions, and if those deals sour it gets written off, so tangible book asks what the equity is worth if the accounting optimism evaporates.

It is the standard equity measure for banks. A bank's assets are mostly financial and close to marked value, so tangible book per share is treated as the floor the franchise is built on, and bank M&A gets negotiated in multiples of it. For a serial acquirer in any sector, the gap between book and tangible book measures how much of the balance sheet is deal premium rather than hard assets.

It punishes the wrong companies if applied blindly. A software firm's most valuable assets — code, brand, customer relationships — are mostly absent from the balance sheet, so its tangible book can be trivial or negative while the business is superb. Tangible book is a solvency lens, not a quality lens.
