<P> This basket is re-evaluated every five years, and the currencies included as well as the weights given to them can then change . A currency's importance is currently measured by the degree to which it is used as a foreign exchange reserve asset and the amount of exports sold in that currency . </P> <P> Because of fluctuating exchange rates, the relative value of each currency varies continuously and so does the value of the XDR . The IMF fixes the value of one XDR in terms of U.S. dollars every day . The latest U.S. dollar valuation of the XDR is published on the IMF website . </P> <Table> <Tr> <Th> Period </Th> <Th> USD </Th> <Th> DEM </Th> <Th> FRF </Th> <Th> JPY </Th> <Th> GBP </Th> </Tr> <Tr> <Th> 1981--1985 </Th> <Td> 0.540 (42%) </Td> <Td> 0.460 (19%) </Td> <Td> 0.740 (13%) </Td> <Td> 34.0 (13%) </Td> <Td> 0.0710 (13%) </Td> </Tr> <Tr> <Th> 1986--1990 </Th> <Td> 0.452 (42%) </Td> <Td> 0.527 (19%) </Td> <Td> 1.020 (12%) </Td> <Td> 33.4 (15%) </Td> <Td> 0.0893 (12%) </Td> </Tr> <Tr> <Th> 1991--1995 </Th> <Td> 0.572 (40%) </Td> <Td> 0.453 (21%) </Td> <Td> 0.800 (11%) </Td> <Td> 31.8 (17%) </Td> <Td> 0.0812 (11%) </Td> </Tr> <Tr> <Th> 1996--1998 </Th> <Td> 0.582 (39%) </Td> <Td> 0.446 (21%) </Td> <Td> 0.813 (11%) </Td> <Td> 27.2 (18%) </Td> <Td> 0.1050 (11%) </Td> </Tr> <Tr> <Th> </Th> <Th> USD </Th> <Th_colspan="2"> EUR </Th> <Th> JPY </Th> <Th> GBP </Th> </Tr> <Tr> <Th> 1999--2000 </Th> <Td> 0.5820 (39%) </Td> <Td> 0.2280 (21%) </Td> <Td> 0.1239 (11%) </Td> <Td> 27.2 (18%) </Td> <Td> 0.1050 (11%) </Td> </Tr> <Tr> <Td_colspan="2"> = 0.3519 (32%) </Td> </Tr> <Tr> <Th> 2001--2005 </Th> <Td> 0.5770 (44%) </Td> <Td_colspan="2"> 0.4260 (31%) </Td> <Td> 21.0 (14%) </Td> <Td> 0.0984 (11%) </Td> </Tr> <Tr> <Th> 2006--2010 </Th> <Td> 0.6320 (44%) </Td> <Td_colspan="2"> 0.4100 (34%) </Td> <Td> 18.4 (11%) </Td> <Td> 0.0903 (11%) </Td> </Tr> <Tr> <Th> 2011--2015 </Th> <Td> 0.6600 (41.9%) </Td> <Td_colspan="2"> 0.4230 (37.4%) </Td> <Td> 12.1000 (9.4%) </Td> <Td> 0.1110 (11.3%) </Td> </Tr> <Tr> <Th> </Th> <Th> USD </Th> <Th> EUR </Th> <Th> CNY </Th> <Th> JPY </Th> <Th> GBP </Th> </Tr> <Tr> <Th> 2016--2020 </Th> <Td> 0.58252 (41.73%) </Td> <Td> 0.38671 (30.93%) </Td> <Td> 1.0174 (10.92%) </Td> <Td> 11.900 (8.33%) </Td> <Td> 0.085946 (8.09%) </Td> </Tr> </Table> <Tr> <Th> Period </Th> <Th> USD </Th> <Th> DEM </Th> <Th> FRF </Th> <Th> JPY </Th> <Th> GBP </Th> </Tr>
