NOTES
(1) The value of the US dollar in terms of the SDR is the reciprocal of the sum of the dollar values, based on market exchange rates, of specified quantities of the first four currencies shown. See SDR Valuation.
The value in terms of the SDR of each of the other currencies shown above is derived from that currency's representative exchange rate against the US dollar as reported by the issuing central bank and the SDR value of the US dollar, except for the Iranian rial and the Libyan dinar, the values of which are officially expressed directly in terms of domestic currency units per SDR. All figures are rounded to six significant digits. See Representative Exchange Rates for Selected Currencies.
(2) The value in terms of each national currency of the SDR is the reciprocal of the value in terms of the SDR of each national currency, rounded to six significant digits.
