I found the dividend situation confusing too. On Google finance the dividend yield is 4%. Afaik, only 10% of the stock is not being held by the saudi government. Assuming 2T market cap, the dividend obligation is 8B$ to shareholders. But the article indicates an order of magnitude higher dividend obligation. Are there dividend obligations above and beyond what's visible in Google finance?
