In 2018, FCX recorded $4.6 billion for proven and probable mineral reserves and other property, plant, equipment and mine development costs associated with the acquisition of PT Rio Tinto Indonesia (refer to Note 2 for further discussion). FCX recorded $1.7 billion for VBPP in connection with the FMC acquisition in 2007 (excluding $544 million associated with mining operations that were sold) and transferred $59 million to proven and probable mineral reserves during 2018 and $752 million prior to 2018 ($112 million in 2017). Cumulative impairments of VBPP total $485 million, which were primarily recorded in 2008. Capitalized interest, which primarily related to FCX’s mining operations’ capital projects, totaled $96 million in 2018, $121 million in 2017 and $92 million in 2016. During 2017 and 2018, FCX concluded there were no events or changes in circumstances that would indicate that the carrying amount of its long-lived mining assets might not be recoverable.
