In US Premium Beef, LLC, et al. v. United States of America, Brattle worked on behalf of the US Department of Justice (DOJ) in a dispute with a beef cooperative. The cooperative sought a $33 million tax deduction tied to the revaluation of financial instruments issued to its members, but this deduction could only be claimed for debt instruments. A Brattle-supported academic expert opined on the equity-like characteristics of these instruments, leading to a favorable settlement for the DOJ with an allowed deduction of only $8 million.
