(Sharecast News) - Allied Universal said its offer for rival G4S had become final after Canada's GardaWorld on Monday declared it would not raise its own bid for the UK security firm.

The US firm said its recommended cash offer of 245p a share valued G4S at approximately £3.8bn.

Allied added that it was waiving down the acceptance condition to 75% from 90% "providing significantly increased deal certainty for G4S shareholders".

It added that it has obtained "substantially all of the required antitrust and regulatory approvals and foreign direct investment clearances in applicable jurisdictions".
