Stanley Black & Decker voluntarily disclosed to federal regulators its international division might have violated the Foreign Corrupt Practices Act (FCPA).

In its annual report published Thursday, the Connecticut-based tool manufacturer said it “identified certain transactions relating to its international operations that may raise compliance questions under the [FCPA].”

The company said it voluntarily disclosed the information to the Department of Justice (DOJ) and the Securities and Exchange Commission. Stanley Black & Decker said it is “cooperating with both agencies in their investigations” and it has hired professional advisers to review and further enhance “relevant policies, procedures, and controls.”
