RLPC-KazMunaiGas $2.5 bln loan oversubscribed -banker

LONDON, July 3 (Reuters) - Kazakhstan oil and gas company KazMunaiGas's [KMG.UL] unsecured $2.5 billion, three-year syndicated loan is oversubscribed ahead of closing, a banking source said on Thursday.

The deal pays a margin of 155 basis points (bps) over LIBOR.

Lenders are invited to commit $200 million for which they will receive an upfront fee of 100 bps, $100 million for 85 bps, $50 million for 70 bps, or $25 million for 60 bps.

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 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 Will Waterman)
