The statute does not define the expression "fair market value", but the expression has been defined in many different ways depending generally on the subject matter which the person seeking to define it had in mind. I do not think it necessary to attempt an exact definition of the expression as used in the statute other than to say that the words must be construed in accordance with the common understanding of them. That common understanding I take to mean the highest price an asset might reasonably be expected to bring if sold by the owner in the normal method applicable to the asset in question in the ordinary course of business in a market not exposed to any undue stresses and composed of willing buyers and sellers dealing at arm's length and under no compulsion to buy or sell. I would add that the foregoing understanding as I have expressed it in a general way includes what I conceive to be the essential element which is an open and unrestricted market in which the price is hammered out between willing and informed buyers and sellers on the anvil of supply and demand. These definitions are equally applicable to "fair market value" and "market value" and it is doubtful if the word "fair" adds anything to the words "market value."
