(9)A risk may evolve over time and, in order to adapt to the evolution of the risk, commodity derivatives initially executed for reducing risk related to commercial activity, may have to be offset through the use of additional commodity derivative contracts that close out those commodity derivative contracts that have become unrelated to the commercial risk. Additionally, the evolution of a risk that has been addressed by the entering into of a position in a commodity derivative for the purpose of reducing risk should not subsequently give rise to the re-evaluation of that position as not being a privileged transaction ab initio.
