Government Investigations and Crisis Management

Internal investigations and organizing third-party committees

When misconduct or violation of the law is discovered within a corporation, it is necessary to promptly investigate the facts, decide on internal disciplinary action, formulate measures to prevent recurrence thereof and file a criminal complaint with the relevant authorities. Depending on the context and nature of the case, companies may be required to set-up a third-party committee, comprised of outside professionals, and be accountable vis-a-vis shareholders. AMT has extensive experience assisting clients undertaking internal investigations and organizing such third-party committees, providing prompt and appropriate support in a manner best suited for each individual case.
