It also estimated development co-operation flows of ten countries that do not report to the DAC at USD 7.5 billion, drawing on publicly-available information. This information is often incomplete, as some providers do not specify which countries financial resources are flowing to, or do not provide this information on an annual basis. Bilateral development co-operation from providers who are not “developed” countries may choose not to publicly report information for various reasons, including the lack of systems in place to collect such statistics, or fear that providing assistance could make them ineligible to also receive development co-operation - though this is not the case (OECD, 2015b).
