Abstract:
This study was undertaken with the objective of asserting the significant determinants
of microfinance profitability in Sri Lankan microfinance institutions. This study is
based on eleven microfinance institutions in Sri Lanka, within the period of 2005-
2010, which are practicing microfinance at present. In this study, profitability is
measured by profitability and sustainability ratios. Determinants of microfinance
profitability are measured by efficiency and productivity, financing structure and
portfolio quality ratios. Profitability is measured by return on equity ratio, return
on assets ratio, and profit margin ratio. Sustainability is measured by operational
self sufficiency ratio. Efficiency and productivity are measured by operating
expense ratio, personal productivity ratio and cost per borrower ratio. Financing
structure is measured by debt/equity ratio. Portfolio quality is measured by writeoff
ratio. Finally, the researcher intends to postulate that, the cost per borrower is
a determinant for return on equity and operational self sufficiency. Besides, the
operating expense ratio and write off ratios are determinants of return on equity,
return on assets and profit margin. Observations of the debt/equity variable of
the study imply causality for the return on assets and operational self sufficiency
as a determinant of respective models.
