Conversion of Facility refers to change of one facility type into another, such as cash credit to term loan, short-term loan to WCTL, or temporary overdraft to regular limit. It affects repayment structure, documentation, security, and approval authority. In MSME underwriting, it helps the bank understand the nature of the requested or existing facility, the repayment route, the security expectations and the conditions that must be tracked after sanction. For example, a term loan, cash-credit limit or guarantee facility can have different repayment, security, pricing and monitoring requirements even for the same borrower. This matters because product structure affects cash-flow assessment, limit sizing, pricing, documentation and monitoring frequency. The common mistake is to look only at the sanctioned amount while ignoring tenor, utilisation behaviour, repayment cycle, renewal terms and closure conditions.
