Whenever the executor of a will or the trustee of a testamentary or inter vivos trust is permitted or required to select assets in kind to satisfy a gift, devise, or bequest, whether outright or in trust, intended to qualify for the federal estate tax marital deduction prescribed by the United States "Internal Revenue Code of 1954," 68A Stat. 392, 26 U.S.C.A. 2056, or any comparable federal statute enacted after July 20, 1965, and the will or trust instrument empowers or requires the fiduciary to satisfy such gift, devise, or bequest by allocating assets thereto at any values other than market values at the date of satisfaction of such gift, devise, or bequest, the executor or trustee shall satisfy such gift, devise, or bequest by distribution of assets having a value fairly representative in the aggregate of appreciation or depreciation in the value of all property, including cash, available for distribution in satisfaction of such gift, devise, or bequest, unless the will or trust instrument expressly requires that distribution be made in a manner so as not to be fairly representative of such appreciation or depreciation.
