Valuation when consideration not solely in money: open market value then alternative methods determine taxable value. Where consideration is not solely in money, taxable value is determined sequentially: first by open market value; if unavailable, by monetary consideration plus the money-equivalent of non monetary consideration when known at the time of supply; if still not determinable, by the value of a like kind and quality supply; and finally by monetary consideration plus the money-equivalent of non monetary consideration as determined under subsequent valuation rules. Valuation techniques include cost plus mark up and reasonable best judgement methods.
