Types of PP&E

• Land: Land includes the ground on which buildings are located, as well as any natural resources on the land.
• Buildings: Buildings include offices, factories, and warehouses used for business operations.
• Machinery: Machinery includes equipment used in the production process, such as manufacturing machines and assembly lines.
• Equipment: Equipment includes office equipment, vehicles, and other assets used in the business but not directly involved in production.
• Furniture and Fixtures: This includes desks, chairs, shelves, and other items used in the office or retail space.

Accounting for PP&E

• Initial Recognition: PP&E assets are initially recorded at their historical cost, which includes the purchase price plus any costs incurred to get the asset ready for its intended use.
• Depreciation: Depreciation is the process of allocating the cost of a PP&E asset over its useful life. This reflects the decline in the asset's value due to wear and tear, obsolescence, or other factors.
• Methods of Depreciation: Common depreciation methods include straight-line, declining balance, and units of production. The choice of method depends on the nature of the asset and how it is used.
• Impairment: If the fair value of a PP&E asset falls below its carrying amount, the asset is considered impaired. An impairment loss is recognized to reduce the carrying amount to its fair value.
• Disposal: When a PP&E asset is disposed of, the company recognizes a gain or loss on the disposal. This is the difference between the proceeds from the sale and the asset's carrying amount.

Analyzing a company's PP&E can provide insights into its capital investments, operational efficiency, and financial stability. Investors and analysts often examine PP&E to assess a company's ability to generate future revenue and maintain its competitive position.
