Moggliden, the company set up to receive income related to the sale of books by the late Swedish crime writer, has reported revenues of 91 million kronor for the last fiscal year, the Expressen newspaper reported.
The continued success of the Millennium books, which sold tens of millions of copies and spawned Hollywood and Swedish-produced films, has generated a total of 288 million kronor in profits in the last three years, including 82.4 million in the last fiscal year.
While revenues for the last year remained strong, they decreased substantially compared to the 135.5 million kronor generated the previous year.
"Sales of the books has peaked and have levelled off somewhat," Stieg Larsson's brother Joakim told the paper, adding that the books were first published seven years ago.
"There will also be income, but not at the same levels. They will likely be at a much lower level in the future."
The late author's brother and father, who together manage Moggliden and the Stieg Larsson estate, have decided to take 10 million kronor in dividends from the company to support causes championed by the late author.
"Eight million of it will go to the Steig Larsson foundation and the remaining two million to the magazine Expo's foundation," Joakim told Expressen.
Stieg Larsson founded Expo in 1995 to investigate the far-right and neo-Nazi movements in Sweden. Larsson was on his way to work at the magazine when he died from a heart attack heart attack in 2004.
The Millennium trilogy books have sold a total of 73 million copies worldwide and have most recently been published in Kazakhstan, Expressen reported.
Joakim Larsson said that next year he and his father plan to give away 45 million kronor of Millennium proceeds to charity.
