Allen & Overy has advised Thai state-owned energy and petrochemical company PTT Plc. on a recent $1.1 billion bond offering.
 
The Oct. 25 bond sale, which was PTT’s first U.S. dollar-denominated issue since 2005, was split between two tranches: a 10-year tranche worth $500 million and a 30-year tranche worth $600 million.
 
The notes are part of a five-year, $2.6 billion fund-raising program that launched in 2010, and will be used to refinance the company’s existing debt.
 
Allen & Overy Hong Kong partner James Grandolfo advised PTT on the transaction. Clifford Chance acted for joint bookrunners Barclays, Citi, Deutsche Bank and J.P. Morgan.
