For the past year, the Malaysian government has said a company called Good Star Ltd, which received $1.03 billion from the scandal-hit 1MDB investment fund, was owned by the fund's joint venture partner, PetroSaudi International Ltd. Now an official with knowledge of a regulatory investigation has confirmed what Malaysia's central bank has recently asserted: Malaysian financier Low Taek Jho was the sole owner of Good Star during its five years as a company. "What I can say for sure is that Jho Low is the exclusive beneficial owner of Good Star," the official said. According to a registration document seen by Reuters, Good Star was incorporated in the Seychelles on May 18, 2009, four months before the initial payment to PetroSaudi. It was dissolved five years later on May 2, 2014. Low, who is most often referred to as Jho Low, was the owner of Good Star throughout those five years, the official said. Both Low, and the government have denied he had anything to do with 1Malaysia Development Bhd (1MDB), a fund Prime Minister Najib Razak founded in September 2009 to invest in strategic property and energy projects. Malaysian companies and banks linked to 1MDB are at the centre of corruption and money laundering probes that have led investigators to look at transactions and financial relationships across the globe - from Malaysia to Singapore and the Seychelles, from Abu Dhabi to offshore companies in the Caribbean, and from the United States to Switzerland. Investigations are being conducted by authorities in the United States, Switzerland, Luxembourg, Singapore, and the United Arab Emirates. ENERGY INVESTMENT? Unravelling the status of Good Star's ownership is important, investigators say, because it will help determine whether 1MDB's funds were misappropriated or used for legitimate investments, as the government maintains. If Low is the sole owner of Good Star, it could indicate that 1MDB funds were not directed to an energy project investment with PetroSaudi but for another purpose, investigators say. The 34-year-old Low has not been charged with any offence in the investigations into 1MDB. He did not reply to requests for comment that were directed to his private equity and advisory firm in Hong Kong, Jynwel Capital, and his whereabouts could not be determined. Najib, who was the chairman of 1MDB's advisory board until recently, has denied any wrongdoing. The Prime Minister's office did not respond to requests for comment about Good Star for this article. 1MDB and the Malaysian finance ministry, which is the sole shareholder of the fund, declined to comment. PetroSaudi was founded in 2005 by Saudi businessman Tarek Essam Ahmad Obaid, a graduate of Georgetown University School of Foreign Service, the company's website says. PetroSaudi and Obaid did not respond directly when asked if the firm owned Good Star. The London-based law firm of Carter-Ruck, speaking on behalf of PetroSaudi, said in an emailed statement: "Our clients categorically deny any wrongdoing in relation to the Joint Venture with 1MDB, and they have made clear that all funds invested by 1MDB in the Joint Venture were returned, with profits." CENTRAL BANK LETTER Good Star's ownership continues to be a matter of debate in Malaysia. The head of Malaysia's parliamentary inquiry into 1MDB last month denied Low was the owner of Good Star. He did so in explaining why he rejected a letter from Malaysia's central bank saying that Low, indeed, was the owner. The parliamentary inquiry chief, Hasan Arifin, from Najib's ruling United Malays National Organisation, said he did not include the confidential letter in his final report on 1MDB because the Bank's source of information was "intelligence grade", which "may be prejudiced against various parties". Arifin declined to comment to Reuters. The central bank did not respond to requests for comment. The former chief executive of 1MDB, Shahrol Halmi, told the inquiry that Good Star was a subsidiary of PetroSaudi, according to the report. 1MDB made two payments to Good Star, in 2009 and 2011, totalling $1.03 billion. What happened to the money after that could not be determined because the inquiry panel was not given information on 1MDB's foreign banking transactions, according to Tony Pua, an opposition member of the parliamentary inquiry. The Wall Street Journal on July 3 of last year reported that global investigators believed that $700 million in cash moved through banks and companies linked to 1MDB before eventually going into Najib's personal bank accounts. None of the investigations across the world into 1MDB have shown any connection between any alleged misappropriation of money linked to 1MDB and the prime minister. Malaysia's Attorney-General Mohamed Apandi Ali cleared Najib in January of any corruption or criminal offences. He said that $681 million, deposited into Najib's personal account in March 2013 before a Malaysian general election, was a gift from a member of Saudi Arabia's royal family and most of it was returned. Saudi Arabia's Foreign Minister Adel al-Jubeir told reporters in April the funds wired into Najib's account from an unspecified Saudi source were "a genuine donation" with no obligations attached.
