Recurrent expenditure expanded almost nineteen-fold over the period, the largest increases occurring in 1993, 1990 and 1987, with N83.14 billion or 156.77%, N10.23 billion or 39.34% and N7.95 billion or 103.27%, respectively. These increases were largely attributable to transfers in respect of public debt charges, increased expenditure on account of Administration comprising General Administration, Defence and Internal Security, upward review of salaries and benefits, and the Political Transition Program, inflation and interest rates, particularly towards eh end of the period. Debt service payments were high when compared with other categories of expenditure. From just under 40 percent in 1985 to 1987, it rose, averaging some 68 percent over the period of 1990 to 1992, before falling to some 86 percent in 1992. This fall is largely attributable to a slight decline in external interest payments and an extra budgetary expenditure of N54.03 billion (39.57%). Public debt charges were followed by expenditures on administration and social and community services, both of which trended downward in the last four years. Social and community services comprised mainly of health and education services. Special attention was given to universities in 1990 and 1992 by way of funding to enable them improve their infrastructure, libraries and research programs.
