This course explains Informal Income Reliability Evaluation and how the credibility and sustainability of informal or undocumented income sources are identified, assessed, and governed within Agri & Rural Commercial Credit. It covers the key dimensions of behavioural patterns, obligations, and risk indicators for sustainable decision-making, along with sector risk, emphasizing the need for structured assessment, clear boundary definition, and independent validation before credit decisions are finalized. The course also distinguishes Informal Income Reliability Evaluation from the credit approval process, and highlights its role within Borrower & Household Profiling, including limit setting, exception handling, and escalation to credit committees.
