The market value of the Fund at the end of 2005 was NOK 1 399 billion. The value increased by NOK 383 billion during the year, NOK 220 billion of which reflected transfers of new capital from the Ministry of Finance.

A weaker krone in relation to the investment currencies increased the value of the Fund, measured in NOK, by NOK 36 billion during the year. The krone exchange rate has no effect, however, on future international purchasing power.
