Intangible personal property is all personal property that is not valuable in itself, but is valuable because of what it represents.
Examples are shares of stock, bonds, accounts receivable, or other loans which are not secured by real property, and shares of ownership in mutual and money market funds. These are essentially items that you own that make money, but are intangible (e.g. not land or houses).
