The Global Fund is a financing mechanism rather than an implementing agency. Programs are implemented by in-country partners such as ministries of health, while the Global Fund secretariat, whose staff only have an office in Geneva, monitor the programs. Implementation is overseen by Country Coordinating Mechanisms, country-level committees consisting of in-country stakeholders that need to include, according to Global Fund requirements, a broad spectrum of representatives from government, NGOs, faith-based organizations, the private sector, and people living with the diseases. This system has kept the Global Fund secretariat smaller than other international bureaucracies. The model has also raised concerns about conflict of interest, as some of the stakeholders represented on the Country Coordinating Mechanisms may also receive money from the Global Fund, either as grant recipients, sub-recipients, private persons (e. g. for travel or participation at seminars) or contractors.
