Talisman Energy Inc. says the acquisition of the company by Repsol SA is now scheduled to be completed on May 8. 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.
