Derivatives eligibility after corporate restructuring: exchanges must reintroduce near, middle and far month contracts if criteria met.
Exchanges may reintroduce derivatives on a post restructured company from its first trading day only if: futures and options on the pre restructured company previously traded; the pre restructured company met a market capitalisation threshold pre restructuring; the post restructured company is likely to be at least one third the size of the pre restructured company by revenues, assets, or analyst valuations in the exchange's view; and the restructuring does not create disqualifying characteristics (e.g., extremely low free float). If conditions are satisfied, exchanges shall introduce near, middle and far month contracts in the initial contract month; thereafter normal eligibility rules govern.
