transfer pricing between foreign units was a little more complicated due to a greater breadth of issues. there were different legal entities, two different sets of regulatory authorities ( for tax, duty, etc.), and two different currencies. in this situation xerox used a market-based transfer price ( market price less a discount). this method conformed to the US tax law and to the rules of most of the other taxing authorities. in addition, market price followed the OECD guidelines. the transfer price denomination (currency) varied based on the product value added (explained in the next section ). the market-based transfer price provided a marin to the selling unit as well as sufficient margin to the buying unit. this enabled the buying unit to be competitive in their local market.
