So property such as speculative investments, royalties, copyrights, and, in some jurisdictions, leaseholds, should be converted in the interest of the remainderman. These are considered to be non-permanent investments, and may be of significantly reduced or no value by the time of the death of the life tenant. On the other hand "future" property, such as a remainder or a reversionary interest, or other property which at present produces no income, is of no immediate benefit to the life tenant. In the interest of the life tenant, such property should be converted into income bearing properties.
