PARIS, June 1 (Reuters) - Money transfer company Wise's London-listed shares were down around 15% at 0900 GMT on Monday, after a report by the Bureau of Investigative Journalism said the company is being investigated by prosecutors in Belgium over EUR500 million ($582.5 million) worth of suspicious transactions.

Wise, which shifted its primary listing to the Nasdaq last month, responded to the report in a statement, without confirming the amount cited.

Here's what Wise said:

o "We are currently working with the Brussels prosecutor to respond to queries about our business, as we routinely do with regulators and law-enforcement authorities," the firm said.

o "No specific findings have been shared with us to date."

o Requests for information from law enforcement agencies and suspicious activity reports "are a normal part of operations and are not, in themselves, indicative of non-compliance with anti-money laundering requirements or of any wrongdoing," it said.

o "Like every financial institution, we face the reality of increasingly sophisticated bad actors attempting to exploit our platform and we continually invest in tech-enabled systems and teams to stay ahead of ever-evolving threats."
