Premise: If the cost of the PP and E acquired equals the book value of the PP and E surrendered, there is no gain or loss (nor a revenue or other financing source), because the exchange of one asset for another of equal value does not provide a net inflow of resources.

Hypothesis: If PP and E acquired cost equals book value of PP and E surrendered, we can assume there was no leakage of money in the process.
Relation: neutral
