ATHENS Nov 15 (Reuters) - Greece's plan to recapitalise its banks does not offer strong incentives for private investors whose participation is necessary to keep the lenders from further burdening a debt-laden state, one of the country's top banks said on Thursday.
"The banking system's recapitalisation is a big challenge," Eurobank Chief Executive Nikos Nanopoulos said in a speech to business figures in Thessaloniki.
"It is a fact that the recapitalisation terms do not finally look that enticing ... for private shareholders," he said, without specifying why the terms were not attractive enough.
On Monday, Athens unveiled a long-awaited framework to recapitalise its banks, whose capital base was nearly wiped out after huge losses from a sovereign debt swap and rising loan impairments because of a deep recession.
Under the plan, banks will have to issue new shares to achieve at least a 6 percent core Tier 1 capital adequacy ratio and convertible bonds or so-called CoCos to boost it up to 9 percent.
The private sector must take up at least 10 percent of the new shares to be issued to keep lenders privately run. The remainder will be taken up by a bank support fund that is funded from the country's bailout.
Greece and its international lenders have earmarked 50 billion euros from the country's 130-billion-euro bailout to recapitalise viable banks.
Authorities have set up a bank support fund, the Hellenic Financial Stability Fund (HFSF), to recapitalise the sector. The fund has already injected 18.5 billion euros into the country's four biggest banks.
Failure to meet the 10 percent private sector participation requirement will mean nationalisation, which Nanopoulos said must be avoided.
Under the recapitalisation plan, the new shares banks will issue will be priced at a 50 percent discount to the average price 50 days prior to the offering.
The HFSF fund, which will provide most of the new capital by buying most of the new shares and all of the convertible bonds banks will be issuing, will become their biggest shareholder. (Reporting by George Georgiopoulos; Editing by Mark Potter)
