From Wikipedia:

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.[4] 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,[4]and financial assets, including such items as accounts receivable, bondsand stocks.
