Fixed assets, also known as a non-current asset or as property, plant, and equipment (PP&E), is a term used in accounting for assets and property which cannot easily be converted into cash. This can be compared with current assets such as cash or bank accounts, which are described as liquid assets. In most cases, only tangible assets are referred to as fixed.

Moreover, a fixed/non-current asset can also be defined as an asset not directly sold to a firm's consumers/end-users. As an example, a baking firm's current assets would be its inventory (in this case, flour, yeast, etc.), the value of sales owed to the firm via credit (i.e. debtors or accounts receivable), cash held in the bank, etc. Its non-current assets would be the oven used to bake bread, motor vehicles used to transport deliveries, cash registers used to handle cash payments, etc. Each aforementioned non-current asset is not sold directly to consumers.

These are items of value which the organization has bought and will use for an extended period of time; fixed assets normally include items such as land and buildings, motor vehicles, furniture, office equipment, computers, fixtures and fittings, and plant and machinery. These often receive favorable tax treatment (depreciation allowance) over short-term assets. According to International Accounting Standard (IAS) 16, Fixed Assets are assets whose future economic benefit is probable to flow into the entity, whose cost can be measured reliably.
