MOSCOW, Feb 26 (Reuters) - Two of Russia's richest men could
trigger a complicated auction known as a "shootout", in a bid to
end their long-running battle for control of mining giant
Norilsk Nickel (Nornickel)          . 
    After a five-year peace deal ended in December, the power
struggle between two major Nornickel shareholders, Vladimir
Potanin and Oleg Deripaska's aluminium giant Rusal          ,
resurfaced earlier this month.
    Potanin offered to buy a stake owned by a third businessman,
Roman Abramovich. Abramovich has a history of good relations
with President Vladimir Putin. Sources say he was installed as a
minority shareholder in 2012 by the Kremlin as part of the deal
to keep the peace. The Kremlin has always denied this. 
    Deripaska tried to block Potanin from buying Abramovich's
stake as it would have given his rival, who is already
Nornickel's chief executive and largest shareholder, even more
control of the company. 
    On Friday, the battle took a new turn when Rusal said it
would ask shareholders for permission for a mandate to authorise
the board to take part in a potential shootout.             
    The terms of the shootout, a price auction between the two
parties, were agreed as part of the 2012 deal and could be used
as of December. 
    The losing side would be forced to sell part or all of its
stake to the winner, effectively giving control of the $33
billion company, the world's top nickel and palladium producer,
to their rival.
    Representatives of Deripaska and Rusal, Potanin and
Nornickel and Abramovich's Millhouse declined to comment. 
    
    PEACE DEAL
    Deripaska and Potanin have periodically been at loggerheads
since Deripaska's Rusal bought a stake in Nornickel in 2008.
Rusal currently owns 27.8 percent of Nornickel and Potanin has
30.4 percent. 
    Chelsea soccer club owner Abramovich and his partners hold a
6.3 percent stake in Nornickel, of which 4.2 percent is owned
via a Cyprus-based company called Crispian. 
    The peace deal involved a five-year lock-up period, during
which no party could sell a chunk of their Nornickel stakes. 
    The Kremlin has said it was following the case but was not 
involved.
    "Taking into account the size and the social and economic
significance of this company, of course, the Kremlin is
following the development of the situation with the management,"
 Kremlin spokesman Dmitry Peskov told reporters on Monday.
    He said the Kremlin should not be involved in shareholder
relationships.
    The deal between Rusal, Potanin and Abramovich says that if
one firm wants to sell, they have to give other stakeholders
first right of refusal. This is not related to the shootout
process which can only be triggered by Rusal and Potanin. 
    Potanin's Cyprus-based firm Bonico made an offer on Feb. 2
to purchase a 4 percent stake in Nornickel from Abramovich's
Crispian for $1.5 billion.             
    Crispian sent Rusal and Potanin's other Cyprus-based firm -
Whiteleave - a letter informing them of the offer and the chance
to buy the stake on the same terms. Both Whiteleave and Rusal
say they accepted Crispian's offer.
    However, Rusal says Crispian's offer is not a valid notice
because Bonico is an affiliate of Whiteleave. Rusal is seeking
an injunction in a London court to block any deal. Whiteleave
says there is no reason to grant an injunction.  
    The court on Feb. 16 agreed to delay the injunction hearing
until the week of March 5 but then said that another hearing
would be held on Feb, 27. Lawyers on all sides asked the court
to complete the trial before June.                          
    Whiteleave has secured $1.5 billion in debt financing for
the possible deal with Abramovich, but says Rusal's court
application will mean losses for Whiteleave if the proceedings
go on for a long time, court materials obtained by Reuters show.
    Crispian has agreed not to transfer its shares in Nornickel
as part of the offer until the hearing is over.
    
    STARTING PRICE
    Tensions could end now if Potanin buys the 4 percent stake
in Nornickel from Abramovich or if Potanin and Rusal share the 4
percent stake between them. According to the agreement between
the three companies, Potanin and Rusal could share Abramovich's
stake if they both want to buy it.  
    But Rusal and Potanin could also both trigger the
"shootout". Analysts still say this is unlikely to happen
because the agreement is vague and requires raising large
capital.
    "We regard an actual sale as highly unlikely as the required
financing ($11-15 billion) looks excessive even for the
state-owned banks, and would require political will, which, in
our view, is uncertain," analysts at Aton said on Thursday. 
    But Rusal's request to shareholders on Friday for permission
"which shall authorise the board to effect the potential
shootout transaction as and when appropriate" appears to put the
idea firmly on the table. 
    According to the shootout agreement, the starting price,
would be based on the six-month average price of Nornickel
shares plus 20 percent.
    The maximum price at which Rusal might make an offer to buy
Potanin's stake in Nornickel is $320 per Nornickel share, Rusal
said in the statement on Friday. The minimum price at which
Rusal could consider selling its stake in Nornickel is $220.8
per share.
    However, Rusal's Board "would suggest that" Rusal should not
accept an offer to sell its stake in Nornickel to Potanin for
less than $320 a share, it added in the statement.
    "We think that the goal of setting the price level is to
deter Interros (a holding company which manages Potanin's
assets) from making an unfair - in Rusal's view - offer first,
rather than prepare for a buyout offer to Interros which we
think is overwhelming for Rusal," analysts at VTB Capital said
on Monday.
    Rusal declined to comment. The majority of shareholders
should vote in favour of the approval to grant the mandate.
    
    HELPFUL PARTNERS
    Analysts have also suggested that partners could help
Deripaska with a shootout purchase if needed.
    Trade and mining giant Glencore          also owns a stake
in Rusal and is buying aluminium from the latter. However,
Nornickel, selling the bulk of its metals under long-term
contracts with end users, has been avoiding working with
Glencore.
    "Given the attractiveness of Norilsk Nickel's commodity
basket (nickel, cobalt, platinum group metals), we believe it
could well be the case that Rusal may fund the stake acquisition
(in a shootout) with the support of a company such as Glencore
that would like to trade Norilsk Nickel's metal," analysts at
Sberbank CIB said. 
    Glencore declined to comment.
    Rusal bought its stake in Nornickel from Potanin's former
partner, Mikhail Prokhorov in 2008.
    During the conflict with Potanin, Deripaska refused to sell
his stake in Nornickel, angering his Rusal partners - Prokhorov
and Viktor Vekselberg and straining their relationship.
    On Feb. 19, Prokhorov agreed to sell a 6 percent stake in
Rusal to a consortium led by Vekselberg. The sale will cut
Prokhorov's stake in Rusal to zero and will increase the stake
of Vekselberg in Rusal to 26.5 percent.
    Glencore and Vekselberg's representative declined to comment
about whether they would vote in favour of granting the shootout
mandate to Rusal's board. A representative of En+          ,
Deripaska's company and the largest shareholder in Rusal, also
declined to comment.
