In addition to the modified threshold requirements, the 1999 revisions introduced several other changes. First, the six-year structure was abandoned and replaced by a "floating completion point" that allows countries to progress towards completion in less than six years. Second, the revised HIPC allows for interim debt relief so that countries begin to see partial relief before reaching the completion point. Third, the PRGF heavily modified ESAF by curtailing the number and detail of IMF conditions and by encouraging greater input from the local community into the program's design.
