Green shoe option enables post listing price stabilisation through a stabilising agent under prescribed procedural safeguards. An issuer may use a green shoe option to stabilise post listing prices if shareholders authorize allotment to a stabilising agent and a lead manager is appointed as stabilising agent. Contracts must be executed before filing offer documents, including agreements to borrow securities for over allotment up to fifteen per cent. The stabilising agent controls timing, quantity and purchase price of market buys during a maximum thirty day stabilisation period, operates special bank and depository accounts, returns or causes allotment of securities to cover shortfalls, and complies with reporting and record retention requirements.
