European private equity firm Triton Partners has offered to buy a portfolio of assets from mid-market firm Zurmont Madison – a deal that would raise fresh questions about the survival of the seller.

Triton has offered just under Sfr82 million ($74 million) for three assets, according to people familiar with the secondaries deal. The assets are: steel products business SMB; electronic engineering services company CCS Holding; and parquet flooring manufacturer Bauwerk Boen.
