The World Bank's current focus is on the achievement of the Millinium Development Goals (MDGs), lending primarily to "middle-income countries" at interest rates which reflect a small mark-up over its own (AAA-rated) borrowings from capital markets; while the IDA provides low or no interest Loans and grants to low income countries with little or no access to international credit markets. The IBRD is a market-based Non-Profit Organisations, using its high credit rating to make up for the relatively low interest rate on its loans, while the IDA is funded primarily by periodic "replenishments" (grants) voted to the institution by its more affluent member countries.
