Well-settled in the tax law is the notion that the character of amounts received in the settlement of a claim turns on the underlying nature of the claim. See Lyeth v. Hoey, 305 U.S. 188 (1930) and its progeny. The same holds true in characterizing amounts paid in settlements and is sometimes referred to as the "origin of the claim doctrine." See, e.g., United States v. Gilmore, 372 U.S. 39 (1963), Woodland v. Commissioner, 397 U.S. 572 (1970), United States v. Hilton Hotels Corp., 397 U.S. 580 (1970).
