External Commercial Borrowings require Form ECB submission with lender and loan details; AD forwards for LRN within seven days. Form ECB (Part V: Annex I) mandates that borrowers submit a completed, certified application in duplicate to a designated Authorised Dealer, who must scrutinise original documents and forward one copy to the Reserve Bank for allotment of a Loan Registration Number. The Form records route (Automatic or Approval), borrower and lender details, loan amounts, drawdown and repayment schedules, interest and hedging terms, security/guarantee information, end-use allocations, prescribed codes, and certifications; incomplete or non conforming submissions may be rejected.
