What should be the remedy when a bankruptcy court holds that a security interest is avoidable as a preferential transfer, but the value of the security interest is not readily ascertainable? The Ninth Circuit recently addressed this issue in USAA Federal Savings Bank v. Thacker (In re: Taylors), 2010 U.S. App. LEXIS 5793 (9th Cir. 2010). The Court held that, since the value of the security interest was not readily ascertainable, the only available remedy is for the bankruptcy court to return the security interest itself, not its value, to the bankruptcy estate.
