Details on the lead bank group and pricing for Petroleum Development Oman's (PDO) USD3.4bn, five-year pre-export facility have emerged. Banca IMI, Bank of China, HSBC, ING, JP Morgan, Natixis, National Bank of Abu Dhabi, Societe Generale, Standard Chartered and Sumitomo Mitsui Banking Corporation are leading the deal, with HSBC acting as the sole international financial adviser, one banking source said. The loan pays a margin of 160bp over Libor with all-in fees coming in at 190bp, the banker said. The deal initially went out to the ten lead banks who were asked to commit USD300m each, but it has now gone out to wider syndication following a bank meeting in London on May 27. The deal is expected to close by the end of June.   PDO - which is majority owned by Oman with stakes also held by Royal Dutch Shell, Total and Partex Oil & Gas - is working closely with Oman's Ministry of Finance and Ministry of Oil and Gas to raise the loan to fund its operations as low oil prices continues to impact revenue .PDO will be a benchmark deal for the sultanate which is looking to raise funds through a number of syndicated loans and its first bond issue in 20 years, which could be as large as USD3bn according to a second banker. Once PDO's loan has been closed, state energy investment firm Oman Oil Company is expected to immediately start the refinancing of a USD1.85bn loan originally signed in September 2014. PDO's deal follows a USD1bn, five-year loan for Oman that closed in January, but only after a protracted syndication. That deal faced difficulty after Standard & Poor's downgraded the country's sovereign debt to BBB+ during syndication in November, which led to pricing on the loan being flexed upwards from 110bp over Libor to 120bp over Libor.
