Halliburton Co. will redeem $2.5 billion of its 2.700% senior notes due March 2020 and its 3.375% senior notes due March 2022 under redemption procedures in the indenture governing the notes. The special mandatory redemption is connected to the termination of Halliburton’s merger agreement with Baker Hughes Inc., the company said May 6.

The notes’ redemption date is May 12. Halliburton said it will use cash on hand to fund the redemption.

The Bank of New York Mellon Trust Co. NA, the trustee, is notifying all current registered noteholders of the redemption.

Halliburton Co. is based in Houston.
