MOSCOW, April 7 (Reuters) - Russian mid-sized bank Nomos has found buyers for its initial public offering (IPO), likely to include a local billionaire and a European fund as core investors, sources told Reuters on Thursday.
Stockholm-based fund manager East Capital may invest around $100 million in Nomos's IPO, two sources said.
Russian tycoon Alexander Mamut -- owner of mobile retailer Euroset and investor in British music retailer HMV -- may put more than $100 million in to the offering, a market source said on Tuesday.
Nomos IPO is fully subscribed, another source told Reuters on Thursday.
Nomos declined to comment. East Capital and Mamut could not be reached for comment.
Risk appetite -- which plunged last month on the nuclear crisis in Japan and unrest in the Arab world -- has improved, sparking renewed interest in listings, with Russian firms leading the charge. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Russian companies seeking IPOs: DEALTALK on current hopefuls: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Nomos, whose offering is expected to price on April 19, said it aimed to sell ordinary shares at $32 to $37, or $16.0 to $18.5 per global depositary receipt (GDR), in London and Moscow.
The shares for sale are mostly existing equity owned by 18.7 percent shareholder Roman Korbacka, as well as new shares worth around 5.5 billion roubles ($194.8 million).
The bank said the offering would value it at $2.8 billion to $3.2 billion. A source close to the deal said previous market estimates of $700 million remained the fund-raising target.
