Noble Group tightens guidance on $500 mln bond sale

HONG KONG, May 22 (Reuters) - Singapore-listed commodities firm Noble Group (NOBG.SI) has tightened guidance for its $500 million sale of five-year bonds, a source familiar with the deal said on Thursday.

Noble Group is seeking to sell the bonds at a yield of 8.375-8.625 percent, down from a guidance of 8.5-8.75 percent provided on Wednesday, said the source, who has been briefed on the deal but asked not to be identified discussing the transaction.

The commodities firm, which is based in Hong Kong, has closed order books for its sale with $4 billion in orders, said the source. Pricing is expected early in the morning in U.S. hours later on Thursday.

"The deal will probably not grow," the source added.

Citigroup (C.N) and JPMorgan (JPM.N) are the lead managers for the sale. (Reporting by Rafael Nam; Editing by Anne Marie Roantree)
