(b) Unless specifically stated otherwise, the reference in the will, trust document, or beneficiary designation to the unified credit, applicable exclusion amount, exemption equivalent, family-owned business deduction, other credit, or other deduction shall be considered to refer to the unified credit, applicable exclusion amount, exemption equivalent, family-owned business deduction, other credit, or other deduction as it exists at the time of death of the individual.
