NDS-OM access via Separate Business Unit: SEBI-registered brokers must segregate SBU operations and net worth. SEBI-registered stock brokers may transact on NDS-OM through a Separate Business Unit (SBU) that is exclusively engaged in NDS-OM activities, maintained at arms-length from the broker's securities market business, with separate accounts and segregated net worth; the broker's net worth for compliance shall exclude the SBU. The SBU's trading activities are subject to the other regulatory authority's framework for policy, eligibility, risk management, inspection and enforcement, and exchange grievance redressal mechanisms and the Investor Protection Fund (including SCORES) will not be available to SBU investors.
