Notes: The number in parentheses are the standard errors. GDP is the macroeconomic measure of the soundness of economy; INF measures the price index; C3 refers to the concentration index; size is measured by total assets; CAP is the total equity to total assets; ROA measures the profitability; LLP/TL represents the credit risk; NII/TA measures the non-interest/ finance income; TL measures the intensity of loans/ finance provided to customers; LN(LIQ) refers to liquidity risks. *,**,***Significant at 1, 5 and 10 per cent level, respectively
