Non-Performing Asset Migration represents movement or risk of movement of an account into NPA status due to overdue principal, interest, or other regulatory triggers. It is a monitoring and portfolio risk concept. Define the applicable regulatory overdue threshold. In MSME underwriting, it is read along with financial statements, bank statements, GST data and existing obligations to judge cash-flow strength and repayment capacity. The trend is usually more important than one isolated number, because MSME financials can be affected by seasonality, accounting treatment and one-off events. For example, the value should be compared across years and reconciled with audited statements, GST returns, bank credits and related schedules. It matters because financial interpretation can change the view on leverage, liquidity, profitability, debt-service ability and the borrower’s real operating strength. The common caution is to check calculation basis, period, exceptional items, related-party entries and consistency with GST, bank statement and audit data.
