Financial projections. The reliability of an estimate of the value of a platform or operating contribution in connection with a PCT will often depend upon the reliability of projections used in making the estimate. Such projections should reflect the best estimates of the items projected (normally reflecting a probability weighted average of possible outcomes and thus also reflecting non-market-correlated risk). Projections necessary for this purpose may include a projection of sales, IDCs, costs of developing operating contributions, routine operating expenses, and costs of sales. Some method applications directly estimate projections of items attributable to separate development and exploitation by the controlled participants within their respective divisions. Other method applications indirectly estimate projections of items from the perspective of the controlled group as a whole, rather than from the perspective of a particular participant, and then apportion the items so estimated on some assumed basis. For example, in some applications, sales might be directly projected by division, but worldwide projections of other items such as operating expenses might be apportioned among divisions in the same ratio as the divisions' respective sales. Which approach is more reliable depends on which provides the most reliable measure of an arm's length result, considering the competing perspectives under the facts and circumstances in light of the completeness and accuracy of the underlying data, the reliability of the assumptions, and the sensitivity of the results to possible deficiencies in the data and assumptions. For these purposes, projections that have been prepared for non-tax purposes are generally more reliable than projections that have been prepared solely for purposes of meeting the requirements in this paragraph (g).
