LONDON (Reuters) - Accor investor CIAM said on Thursday that Europe's largest hotel group was undervalued by public markets and a good potential target for a private equity buyer.

Catherine Berjal, CEO of CIAM, also told the Sohn conference in London, that a private equity buyer could dispose of Accor's non-core financial assets and return up to 35% of its market cap in cash.

Other steps to add value would include selling its luxury franchises and investing in its remaining business.

According to a source close to the matter CIAM has less than 1% in Accor, and did not view its investment as an activist position.

The Sohn conference brings together hedge fund managers invited to pitch ideas. Accor declined to comment.
