Does Saudi Arabia have the cash to pay ?
Way, way more than enough. This deal is a drop in the Saudi money bucket.
Consider:
The worlds largest oil exporter known formally as the government-owned Saudi Arabian Oil Co. holds a concession to pump the kingdoms oil and gas, and a stake in that business is what the Saudi government will sell in an Initial Public stock Offering (IPO) of not far from 5 percent of company shares in 2018. Analysts at Sanford C. Bernstein & Co. and Rystad Energy AS said that the IPO has a potential market value of more than $1 trillion.
The bottom line is that the minute Saudi Oil goes public, it becomes the richest publicly traded company on the planet, surpassing Apple, Alphabet (Google), Microsoft, Amazon and Facebook.
