Norilsk Nickel said on Friday its 2012 net profit fell 41 percent year on year due to write-offs and a decline in metal prices.
Norilsk's net profit of $2.14 billion for last year, was hit by $976 million in write-offs. A poll of analysts had expected net profit of $2.89 billion.
The write-offs included investment-related losses of $552 million mainly from a decline in share price of Russian energy group InterRao, in which Norilsk has about 13 percent. There was also a $278 million impairment loss related to Norilsk's assets in Botswana and Australia.
Norilsk shareholder RusAl said in December the mining group might pay a total of up to $9 billion in dividends for 2012 and the following two years, part of a peace deal between billionaires Vladimir Potanin, Norilsk's CEO, and RusAl owner Oleg Deripaska.
