FD Details refers to details of Fixed Deposits linked to the borrower, facility, margin, lien, collateral, or repayment arrangement. It includes deposit amount, maturity, lien status, and ownership. In MSME underwriting, it supports the bank’s secondary repayment comfort by identifying what security is available, who owns it, how it is valued and whether the charge can be enforced. For example, a fixed deposit offered as security may reduce loss risk, but lien marking, maturity date and ownership must be checked. It matters because collateral can reduce loss severity, support sanction conditions and improve exposure comfort when business cash flows are volatile. The common mistake is to rely only on stated value; title defects, prior charges, documentation gaps and valuation haircuts can materially weaken security comfort.
