During the fourth quarter of 2017, we committed to a plan to divest our land drilling rigs assets. As such, we reclassified the carrying amounts of the assets we plan to divest as held for sale as of December 31, 2017, which include $276 million of PP&E and other assets and $64 million of inventory. As of December 31, 2017, we also had $19 million of other PP&E held for sale.
