The Calgary-based company says the required regulatory approvals are in hand and completion remains subject to the satisfaction of customary closing deliverables.
Talisman agreed late last year to be bought by Repsol in a deal worth about $13 billion, including $8.3 billion for Talisman stock plus the assumption of its debt.
The company said in February that its shareholders had voted more than 99 per cent to approve the takeover by Spain-based Repsol.
Also in February, Talisman reported a loss of US$1.59 billion in the fourth quarter of 2014, or $1.54 per share. That compared to a loss of $1 billion, or 98 cents per share, in the same quarter a year earlier.
Talisman's main operations are in North America, Colombia and Asia.
