Fiduciary Liability, also known as pension trust liability, provides coverage for loss that the insured becomes legally liable to pay because of a claim made against the insured for any alleged wrongful act by such insured or by any other person for whom the insured is legally responsible. It also covers the defense costs in connection with a covered claim. The policy is written on claims made form. A wrongful act includes any violation of responsibilities, obligations, or duties imposed on fiduciaries by the Employee Retirement Income Security Act (ERISA), as well as acts, errors, or omissions in the performance of the duties of the plan administrator.
