Maryland Estates and Trusts Section 15-403

      Section 15-402 does not apply if the applicable gift instrument indicates the intention of the donor that net appreciation shall not be expended. A restriction upon the expenditure of net appreciation may not be implied from a designation of a gift as an endowment, or from a direction or authorization in the applicable gift instrument to use only "income", "interest", "dividends", or "rents, issues or profits", or "to preserve the principal intact", or a direction which contains other words of similar import. This rule of construction applies to gift instruments executed or in effect before or after the effective date of this act.
