Pledged shares are collateral for a loan; invoking the
shares means the lender transfers the shares to itself when the borrower fails
to pay back the loan.
Invoking means that the lender has exercised his right on
security and the shares have been actually transferred from the demat a/c of
borrowers to the demat account of lenders. To that extent the promoters holding
has reduced and lender has the liberty to sell the shares at any time and sue
the borrower for balance amount.
If the loan is not repaid, the pledgee, after giving notice
to the pledgor as per the terms of the agreement, may instruct its DP to invoke
the pledge by submitting the "Pledge Form" with a tick on
"Invoke Pledge". On execution of this instruction, the securities are
transferred into the pledgee's account. This does not require any confirmation
from the pledgor.
