Saudi Aramco's board has concluded that listing the oil giant on the New York Stock Exchange would carry a lot of legal risk to make it a realistic option, although it said the final decision was in the hands of Saudi Crown Prince Mohammed bin Salman, five sources said.

The sources said New York was the stock exchange favored by Prince Mohammed bin Salman before the IPO was suspended last year, even after Aramco's lawyers and some government advisers raised legal concerns, Reuters reported on Friday.

New York offers the world's largest investor base and is vital to the IPO, which aims to attract up to $ 100 billion, an amount that may be difficult for other exchanges to raise. US President Donald Trump has urged the kingdom to list Aramco in New York.

A source familiar with the IPO said the board, made up of government ministers and executives of Aramco, concluded at a meeting this month that it would not consider listing the company in the United States, "unless Aramco is granted sovereign immunity that protects it from any legal process."

"This is of course difficult, if not impossible," the source told Reuters.

The Saudi crown prince hopes to make Aramco worth $ 2 trillion, while some insiders and bankers say the figure is too high.

Realistic subtraction
Sources also said the move to exclude New York and Aramco's devaluation suggests that company and government experts are pushing for a more realistic plan for the IPO.

Alongside New York, the London, Hong Kong and Tokyo exchanges are keen to woo Saudi officials to secure a deal to trade shares in Aramco, which is expected to have a major listing in Riyadh.

But Saudi officials say the New York disclosure procedures and complex regulations may legally interfere with the sovereignty of the Saudi government, which will remain Aramco's main shareholder and is likely to retain a 95 percent stake.

"Listing in New York is no longer an option," said a source familiar with the IPO.

Four sources said Riyadh and London were now the two main options, with a domestic listing first followed by an international offering at a later stage.

Another source familiar with the IPO said that "the probability of local listing is increasing, with 1% to 2% of Aramco being listed locally," adding that "the other possibility is listing in London."

Three sources said the potential litigation risks in the United States include the Justice Against Terrorism Act (Justa) and proposed US legislation known as Nubik, which could lead to Aramco being sued in US courts.

Another source who discussed the IPO with Saudi officials said: "The whole system is very much inclined to appeal to the judiciary, but of course Aramco has a lot of investment in the US that will continue."

Aramco may also find itself involved in ongoing lawsuits against US oil companies for their role in climate change, the sources said.

Aramco responded
In response to a question from Reuters whether New York was excluded as a listing site, Saudi Aramco said in a statement it "continues to engage with the shareholder on IPO preparation activities."

She added that "the company is ready and will depend on the timing of market conditions and be at a time chosen by the shareholder."

According to sources familiar with Saudi thinking, the crown prince preferred listing on the New York Stock Exchange, partly because of Riyadh's long-standing ties with Washington. Aramco began its activities in the 1930s as a US-Saudi project.

The sale of a 5% stake in Aramco is central to Vision 2030, a plan to diversify the Saudi economy away from oil, but the initial public offering, which was initially expected to take place in 2017, has faced repeated delays.

Currently, the IPO is not expected until Aramco completes a majority stake in petrochemical giant Saudi Basic Industries Corp (SABIC), which will delay it until 2020 or 2021.
