The article, “Estate Tax Repeal” on page 10 of the mid-February Cow-Calf Issue on estate planning, incorrectly referred to a 2003 book by New York Times tax writer David Cay Johnston. The correct title is: “Perfectly Legal: The Covert Campaign To Rig Our Tax System To Benefit The Super Rich — And Cheat Everybody Else.” We apologize for the error.
