In a notice issued on February 15, 2018, the Securities and Exchange Commission of the US highlighted various concerns, including whether the deal would allow it to supervise the exchange properly. The SEC said that during its review, it was unable to obtain all the information it needed from the Chinese-led group of investors, including details about how some of the entities involved in the deal were funded. The regulator said this "raises significant doubts" that it would be able to monitor the exchange if the deal went through.
