was determined as follows:

Finished goods—Estimated selling price, less an estimate of costs to be incurred to sell the inventory, and an estimate of a reasonable profit allowance for that selling effort.

Work in process—Estimated selling price of an equivalent finished good, less an estimate of costs to be incurred to complete the work-in-process inventory, an estimate of costs to be incurred to sell the inventory and an estimate of a reasonable profit allowance for those manufacturing and selling efforts.

Raw materials and supplies—Estimated cost to replace the raw materials and supplies.

The fair value of inventory is recognized in our results of operations as the inventory is sold. Some of the more significant estimates and assumptions inherent in the estimate of the fair value of inventory include stage of completion, costs to complete, costs to dispose and selling price. All of these judgments and estimates can materially impact our results of operations.

• Property, Plant and Equipment—The fair value of acquired property, plant and equipment is determined using a variety of valuation approaches, depending on the nature of the asset and the quality of available information. If multiple approaches are used for a single asset or a group of assets, those approaches are compared and reconciled to arrive at a single estimate of fair value. The fair value of acquired property, plant and equipment was primarily determined as follows:

O Land––Market, a sales comparison approach that measures value of an asset through an analysis of sales and offerings of comparable property.

O Buildings—Replacement cost, an approach that measures the value of an asset by estimating the cost to acquire or construct comparable assets. For buildings that are not highly specialized or that could be income producing if leased to a third party, we also considered market and income factors.

O Machinery and Equipment—Replacement cost. O Furniture and Fixtures—Replacement cost.

O Construction in Progress—Replacement cost, generally assumed to equal historical book value.

The amounts recorded for the major components of acquired property, plant and equipment are as follows:

       The fair value of property, plant and equipment will be recognized in our results of operations over the expected useful life of the individual depreciable assets.

Some of the more significant inputs, estimates and assumptions inherent in the estimate of the fair value of property, plant and equipment include the nature, age, condition or location of the land, buildings, machinery and equipment, furniture and fixtures, and construction in progress, as applicable, as well as the estimate of market and replacement cost and the determination of the appropriate valuation premise, in-use or in-exchange. The in-use valuation premise assesses the value of an asset when used in combination with other assets (for example, on an installed basis), while the in-exchange valuation assesses the value of an asset on a stand alone basis. All of these judgments and estimates can materially impact our results of operations.

• Identifiable Intangible Assets—The fair value of acquired identifiable
