The goal of this paper is to inform readers about a valuation issue that is the subject of a petition put before the United States Supreme Court to resolve a circuit split. The issue is how does corporate-owned life insurance designed to fund the redemption of a deceased shareholder’s stock impact the fair market value of the subject company and the value of the decedent’s gross estate. The author examines the applicable U.S. Tax Court, district court, and two appellate decisions so the reader can understand the arguments made and the basis for the legal conclusions.
