Energy, Inc., 188 F.3d 116, 122 (3d Cir.1999). As the relevant facts are undisputed, this appeal presents a pure question of law, which we review de novo. See id. II. A. Section 510(b) of the Bankruptcy Code provides: For the purpose of distribution under this title, a claim arising from rescission of a purchase or sale of a security of the debtor or of an affiliate of the debtor, for damages arising from the purchase or sale of such a security, or for reimbursement or contribution allowed under section 502 on account of such a claim, shall be subordinated to all claims or interests that are senior to or equal the claim or interest represented by such security, except that if such security is common stock, such claim has the same priority as common stock. In this ca Bankr.S.D.Fla.1999) (<HOLDING>). In construing § 510(b), we begin, as we must,
