however, from the very beginning, kafka made it clear that he was not going to focus narrowly on relations between his constituency and the fund. rather, he was going to speak out for the interests of the developing world and make sure that their voices were heard. in 1966, the compensatory financing facility (cff) was just beginning to be a major source of financing for commodity-exporting countries. some of his earliest interventions aimed to strengthen its role. throughout his tenure on the board, he fought to expand the usefulness of the cff and to prevent it from being reduced to a standard conditional facility. in the 1960s, he helped formulate the special drawing rights (sdr) system in a way that would benefit developing as well as industrial countries. in the 1970s, he was instrumental in the creation and design of the extended fund facility, and he helped build a consensus for the oil facilities of 1974 and 1975. following the collapse of the bretton woods system in the early 1970s, he served as vice-chairman of the deputies of the committee of twenty, the forerunner of the international monetary and financial committee (imfc). in the 1980s, he stressed the importance of enlarged access to fund resources, insisted that the international debt crisis could not be solved until the developed countries assumed more responsibility for it, and worked for the creation and expansion of concessional lending facilities for low-income countries. in the 1990s, he continued to advocate systemic solutions to the problems of the developing world, through innovations such as the hipc initiative.
