While each sub-system has a particular process for planning and allocating funds, as with all policies and programmes financed with public funds, the budget process starts in June with the elaboration of the Annual Operation Programmes (Programa Operativo Annual, POA). These plans are presented by sector or Ministry to the Ministry of Finance, which makes the ultimate decisions on how funds are allocated. This gets integrated into the Federal Budget (Presupuesto de Egresos de la Federación, PEF) initiative that then goes to Congress for final approval. According to the Budget and Expenditure Legislation, the Federal Budget initiative has to be submitted no later than September 8 of each year to the Chamber of Deputies, which has the exclusive power to approve it no later than November 15 and then be published in the Official Gazette of the Federation no later than 20 calendar days after its approval (Ley Federal de Presupuesto y Responsabilidad Hacendaria).
