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. For more information regarding Morgan Stanley’s role with respect to a Retirement Account, please visit www.morganstanley.com/disclosures/dol. Tax laws are complex and subject to change. Morgan Stanley does not provide tax or legal advice. Individuals are encouraged to consult their tax and legal advisors (a) before establishing a Retirement Account, and (b) regarding any potential tax, ERISA and related consequences of any investments or other transactions made with respect to a Retirement Account. Individuals should consult their tax advisor for matters involving taxation and tax planning and their attorney for matters involving trust and estate planning, charitable giving, philanthropic planning and other legal matters.
