Write-Up in Accounting

A write-up in accounting is an upward adjustment to the recorded value of an asset, increasing its carrying amount on the balance sheet above its previously recorded figure. It is the opposite of a write-down. Write-ups are rare under U.S. Generally Accepted Accounting Principles because GAAP follows the historical cost principle, which prohibits increasing an asset's value above its original cost basis. International Financial Reporting Standards allow write-ups in specific circumstances.

Think of a write-up like revising a test grade upward: it happens, but the rules that govern it are strict and the circumstances narrow.

When Write-Ups Are Permitted Under IFRS

IFRS allows the revaluation model for property, plant, and equipment under IAS 16 and for intangible assets under IAS 38. Under this model, a company can measure an asset at its fair value after initial recognition. If the fair value rises above the carrying amount, the company records a write-up. The increase goes directly to other comprehensive income as a revaluation surplus, not through the profit and loss statement.

This treatment is most common in industries where asset values fluctuate significantly, such as real estate, mining, and utilities. A mining company holding mineral rights that increase in value as commodity prices rise can reflect that increase on its balance sheet under IFRS.

Write-Ups in Acquisitions and Purchase Price Allocations

In an acquisition, U.S. GAAP and IFRS both require purchase price allocation, which assigns the acquisition price to all identifiable assets and liabilities at fair value. If the acquired company's assets are worth more than their book value, the acquirer records them at the higher fair value on the date of acquisition. This effectively writes up the assets to fair value at the moment of the acquisition.

For example, if an acquired company carries property at $2 million book value but independent appraisers value it at $5 million, the acquirer records the property at $5 million. The $3 million difference is not goodwill; it is a fair value step-up on identifiable assets. That step-up generates higher future depreciation charges, which reduce the acquirer's reported earnings after the deal closes.

Write-Ups vs. Goodwill Impairment Reversals

Goodwill created in an acquisition cannot be written back up under either GAAP or IFRS. Once goodwill is impaired, the impairment is permanent. Other assets written down under IFRS can be reversed if the recoverable amount later exceeds the carrying amount, with the reversal capped at what the carrying amount would have been had no impairment been recognized. U.S. GAAP prohibits reversals of impairment losses for most long-lived assets.

Why Write-Ups Matter to Analysts and Investors

A write-up changes the balance sheet but does not generate cash. If a company revalues its real estate portfolio upward by $500 million under IFRS, its equity increases by $500 million but its operating cash flow does not change at all. You need to strip out non-cash revaluation movements when assessing underlying profitability and cash generation.

Write-ups also affect return on assets calculations. When asset values rise through revaluation, the denominator in your return on assets calculation grows without a corresponding increase in earnings, which depresses the ratio. Comparing return on assets across companies that use different measurement models requires adjusting for this difference.
