In financial accounting, an asset is any resource owned by the business. Anything tangible or intangible that can be owned or controlled to produce value and that is held by a company to produce positive economic value is an asset. Simply stated, assets represent value of ownership that can be converted into cash (although cash itself is also considered an asset).^[1] The balance sheet of a firm records the monetary^[2] value of the assets owned by that firm. It covers money and other valuables belonging to an individual or to a business.^[1]

One can classify assets into two major asset classes: tangible assets and intangible assets. Tangible assets contain various subclasses, including current assets and fixed assets.^[3] Current assets include inventory, while fixed assets include such items as buildings and equipment.^[3] Intangible assets are nonphysical resources and rights that have a value to the firm because they give the firm some kind of advantage in the marketplace.

Examples of intangible assets include goodwill, copyrights, trademarks, patents and computer programs,^[3] and financial assets, including such items as accounts receivable, bonds and stocks.

An asset is a resource controlled by the entity as a result of past events and from which future economic benefits are expected to flow to the entity.

It is the result of a past event or transaction.^[5]

One of the most widely accepted accounting definitions of asset is the one used by the International Accounting Standards Board.^[6] The following is a quotation from the IFRS Framework: "An asset is a resource controlled by the enterprise as a result of past events and from which future economic benefits are expected to flow to the enterprise."^[7]

This means that:

Employees are not considered assets like machinery is, even though they can generate future economic benefits.

This is because an entity does not have sufficient control over its employees to satisfy the Framework's definition of an asset.

Resources that are expected to yield benefits only for a short time can also be considered not to be assets, for example in the USA the 12 month rule excludes items with a useful life of less than a year.

Similarly, in economics an asset is any form in which wealth can be held.

There is a growing analytical interest in assets and asset forms in other social sciences too, especially in terms of how a variety of things (e.g. personality, personal data, ecosystems, etc.) can be turned into an asset.^[8]

In the financial accounting sense of the term, it is not necessary to be able to legally enforce the asset's benefit for qualifying a resource as being an asset, provided the entity can control its use by other means.

The accounting equation is the mathematical structure of the balance sheet. It relates assets, liabilities, and owner's equity:

Assets are listed on the balance sheet. On a company's balance sheet certain divisions are required by generally accepted accounting principles (GAAP), which vary from country to country.^[9] Assets can be divided into e.g. current assets and fixed assets, often with further subdivisions such as cash, receivables and inventory.

Assets are formally controlled and managed within larger organizations via the use of asset tracking tools.

These monitor the purchasing, upgrading, servicing, licensing, disposal etc., of both physical and non-physical assets.

Current assets are cash and other assets expected to be converted to cash or consumed either in a year or in the operating cycle (whichever is longer), without disturbing the normal operations of a business.

These assets are continually turned over in the course of a business during normal business activity.

There are 5 major items included into current assets:

Marketable securities: Securities that can be converted into cash quickly at a reasonable price.

The phrase net current assets (also called working capital) is often used and refers to the total of current assets less the total of current liabilities.

Often referred to simply as "investments".

Long-term investments are to be held for many years and are not intended to be disposed of in the near future.

This group usually consists of three types of investments:

Different forms of insurance may also be treated as long term investments.

Also referred to as PPE (property, plant, and equipment), these are purchased for continued and long-term use in earning profit in a business. This group includes as an asset land, buildings, machinery, furniture, tools, IT equipment, e.g., laptops, and certain wasting resources e.g., timberland and minerals. They are written off against profits over their anticipated life by charging depreciation expenses (with exception of land assets). Accumulated depreciation is shown in the face of the balance sheet or in the notes. An asset is an important factor in a balance sheet.

These are also called capital assets in management accounting.

Intangible assets lack of physical substance and usually are very hard to evaluate.

They include patents, copyrights, franchises, goodwill, trademarks, trade names, etc. These assets are (according to US GAAP) amortized to expense over 5 to 40 years with the exception of goodwill.

Websites are treated differently in different countries and may fall under either tangible or intangible assets.

Tangible assets are those that have a physical substance, such as currencies, buildings, real estate, vehicles, inventories, equipment, art collections, precious metals, rare-earth metals, Industrial metals, and crops.

Depreciation is applied to tangible assets when those assets have an anticipated lifespan of more than one year. This process of depreciation is used instead of allocating the entire expense to one year.^[10]

Tangible assets such as art, furniture, stamps, gold, wine, toys and books have become recognized as an asset class in their own right^[11] and many high-net-worth individuals will seek to include these tangible assets as part of their overall asset portfolio. This has created a need for tangible asset managers.
