It is essential to speed up recovery efforts on profitability, French Finance Minister Francois Baroin told Jean-Cyril Spinetta, the president of French power and transport engineering group Areva SA (AREVA.FR) in a letter, published Monday by French Internet news site Owni.

"Given the major challenges which are faced after Fukushima, it is necessary to restore the group's profitability so that it can finance its development projects," Baroin wrote.

"The board of directors should strive to reach the new objectives fixed for 2012 and a double-digit operational margin as quickly as possible, in any case, by 2015 at the latest," Baroin wrote, adding that "these objectives aim to create value for the group's shareholders."

The French state-controlled nuclear engineering firm warned in July that even as it continued to believe in nuclear power as a viable long-term energy source, it was still assessing the impact of the Fukushima nuclear accident on the global nuclear market and couldn't yet issue long-term guidance on the effects of the disaster.

In the first half, Areva's net profit stood at EUR351 million, down from EUR843 million a year earlier. Its operating profit stood at EUR710 million, compared to an operating loss of EUR485 million a year earlier.

A spokeswoman said that it was "an ordinary letter that the state, as the group's majority shareholder, has sent to the board of directors" and that the letter dated from several months ago.
