SDRs are allocated to countries by the IMF.[citation needed] Private parties
do not hold or use them.[Williamson 2] As of March 2011, the amount of SDRs
in existence is around XDR 238.3 billion, but this figure is expected to
rise to XDR 476.8 by 2013.[3] http://en.wikipedia.org/wiki/Special_Drawing_Rights
