The bonds are expected to be issued under the company's $5 billion guaranteed debt issuance program currently rated BBB-, Fitch said.
Under the terms of the securities, noteholders will rely on a senior unsecured guarantee from TNK-BP International Ltd. for repayment, Fitch said.
The bond's issue amount will be disclosed and a final rating assigned later. The final rating is contingent upon receipt of final documents conforming to information already received, Fitch said.
On March 2, 2007, Fitch upgraded TNK-BP International Ltd's $5 billion guaranteed debt issuance program to BBB- from BB+, and also its local and foreign currency Issuer Default ratings to BBB- from BB+ with stable outlook, the agency said.
