In May 2017, we sold our equity interest in IronPlanet Holdings Inc. for $93 million. We recognized a pretax gain of $85 million (included in Other income (expense)) and derecognized the carrying value of our noncontrolling interest, which was included in Other assets in Statement 3. The gain on the disposal is included as a reconciling item between Segment profit and Consolidated profit before taxes.
