RLPC-KazMunaiGas to launch $2.5 bln loan Monday - source

LONDON, June 6 (Reuters) - Kazakhstan oil and gas company KazMunaiGas [KMG.UL] will launch syndication on Monday of a $2.5 billion, three-year unsecured loan, a banking source said on Friday.

Mandated lead arrangers are ABN AMRO, Bank of Tokyo-Mitsubishi-UFJ, Barclays, Credit Suisse, Deutsche Bank, SMBC, Societe Generale and WestLB.

Proceeds will refinance the company's $3.1 billion, one-year unsecured bridge loan that signed in January.

That unsecured loan paid a margin of 90 basis points (bps) over LIBOR and was used to fund the borrower's purchase of Romania's second-largest oil company Rompetrol. (Reporting by Christopher Mangham; Editing by David Holmes)
