What happens if a broker goes down or closes down?

Could you please clarify this statement. Did not understand. Are u correlating cdsl or nsdl where all our investments are lodged could fail like lehman or asking what would happen if brokers fail?

Lehman was an investment bank

It is for this reason it is critical for all of us to ensure what ever we buy is reconciled with our holdings at cdsl or nsdl. We get periodic statements from them.

There are similar post in this forum as to what happens if brokers go bankrupt

If my broker goes bankrupt, are my shares in demat account safe?
