CrossHarbor Capital Partners, a private-equity company in Boston, plans to buy the bankrupt Yellowstone Club for $115 million, according to a person familiar with the situation.

The offer comes after a bankruptcy auction where CrossHarbor and Credit Suisse vied for ownership of the Montana club. Credit Suisse loaned the gated ski resort $375 million in 2005. The club sought protection from creditors in November as real estate sales slowed.

CrossHarbor’s offer is $35 million in cash and $80 million in debt, according to the person.

A Credit Suisse spokesman had no immediate comment and a spokesman for CrossHarbor declined to comment.
