Bids for the takeover of Irish Continental Group (ICG) must be submitted by 5pm today following the extension of the deadline on Friday.
Thursday's noon deadline was moved after competing consortiums Aella and Moonduster failed to submit their bids for the group.
Each party was asked to submit their highest offer after offering the same amount - €22 a share - for ICG, which valued the ferry operator at €560.9 million.
Aella, which holds 17.19 per cent of ICG, is led by ICG chief executive Eamonn Rothwell, and Moonduster, which holds 20.38 per cent of ICG, comprises One51 and the Doyle shipping group and is led by Philip Lynch.
A statement issued by ICG's independent directors on Friday said there was no guarantee that an offer likely to succeed would come in the current process.
