The Bangko Sentral ng Pilipinas (BSP) Monetary Board has revoked the registration of three companies, due to "significant violations."

In a statement Wednesday, the policy-setting monetary board said it has cancelled the registration of Philrem Service Corporation (Philrem), Werquick, Inc. (Werquick), and Peso Remittance Express, Inc. (Peso Remittance).

Philrem, which has been dragged in the $81-million Bangladesh money laundering scam, loses its rights to do business as a remittance agent.

Werquick can no longer be a Foreign Exchange Dealer, money changer, and remittance agent while Peso Remittance is no longer registered to do foreign Exchange, money change, and as remittance agent.

The Monetary Board cited, but did not enumerate, "significant violations" of Section 4511N of the Manual of Regulations for Non-Bank Financial Institutions and Circular No. 706 dated 5 January 2011, also known as the Anti-Money Laundering Rules and Regulations.

BSP said it will work with authorities in probing the violations the companies committed.

"The BSP will also be working closely with other relevant government agencies, such as the Anti-Money Laundering Council and the Department of Justice, in their investigation of possible criminal and administrative violations under the Anti-Money Laundering Act and its Implementing Rules and Regulations, of the aforementioned entities, including their Directors and Officers," the statement read.
