1When Morgan Stanley Smith Barney LLC, its affiliates and Morgan Stanley Financial Advisors and Private Wealth Advisors (collectively, “Morgan Stanley”) provide “investment advice” regarding a retirement or welfare benefit plan account, an individual retirement account or a Coverdell education savings account (“Retirement Account”), Morgan Stanley is a “fiduciary” as those terms are defined under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and/or the Internal Revenue Code of 1986 (the “Code”), as applicable. When Morgan Stanley provides investment education, takes orders on an unsolicited basis or otherwise does not provide “investment advice”, Morgan Stanley will not be considered a “fiduciary” under ERISA and/or the Code.
