Manufacturers rely heavily on tangible assets, so the balance sheet is a logical starting point. Some items are worth more (or less) than book value.
For example, manufacturers sometimes use the same depreciation methods for book and tax purposes. Accelerated depreciation methods, including expanded Section 179 and bonus depreciation deductions available in recent years, have significantly lowered the net book values of fixed assets — including machines, large tools, heavy-duty vehicles, computers, software and office furniture — below current market values.
Receivables also may need to be adjusted for bad debts. Inventory may include obsolete or unsalable items. And contingent liabilities — such as pending lawsuits, environmental obligations and warranties — also must be accounted for.
But the biggest adjustment is for intangible assets, such as internally developed patents, brands and goodwill. The cost approach generally omits the intangible value, but it can serve as a useful “floor” for a company’s value. Appraisers typically use another technique to arrive at an appraisal that’s inclusive of these intangibles.
