In accounting , anything of value that a person or firm buys . Assets can be physical, such as real estate or stocks , a claim on debts , such as accounts receivable or liens , or a right, such as a patent . Of crucial importance to assets is their relative liquidity , or the ease with which they can be converted to cash . Liquid assets are often thought to be more useful than illiquid assets.
