             Green Shoe Option (GSO) is a process of allocating shares in excess of the no. of shares mentioned in the offer document.
The issuer company appoints one of the lead Book runner as the "Stabilising Agent" (SA). The SA enters into an agreement with the Promoters of the Company who agree to lend their shares to the extent of proposed overallotment( max. 5% shares) 
The SA then opens a GSO demat account and a GSO bank account. The money received from the applicants to extent of overallotmnet is kept separately in GSO bank account. This money is then used to buy shares to the extent of overallotment from the market during the stablilsation period and these shares are kept in GSO demat account
These shares are then returned to the promoters, in any case not later then 2 days from the close of stabilisation period.
Thus GSO operates as a post listing price stabilisation mechanism
