It provided around $61 billion in loans and assistance to "developing" and transition countries in the 2014 fiscal year. The bank's stated mission is to achieve the twin goals of ending extreme poverty and building shared prosperity. Total lending as of 2015 for the last 10 years through Development Policy Financing was approximately $117 billion. Its five organizations are the International Bank for Reconstruction and Development (IBRD), the International Development Association (IDA), the International Finance Corporation (IFC), the Multilateral Investment Guarantee Agency (MIGA) and the International Centre for Settlement of Investment Disputes (ICSID).
