The study on the effect of corporate governance on performance of SACCOs was based on the revelations that some cooperatives are ailing, while others are very vibrant and sustainable. Good corporate governance is now accepted as vital to achieving the Millennium Development Goals and as a pre-condition for sustainable economic growth. Corporate governance was operationalized by transparency and accountability, shareholder involvement, policies and guidelines, and rewards and incentives while performance of SACCOs was characterized by growth in share capital/deposits, growth in membership, growth in turnover, and customer satisfaction.
