During 2017, 2016 and 2015, the Company capitalized interest of approximately $0.8 million, $0.7 million and $0.3 million, respectively.

During the fourth quarter of 2017, the Company completed a global design review of the next phases of its enterprise resource planning system implementation. Through this review, the Company identified certain software items that were no longer useful to the future phases of the enterprise resource planning system. As a result, the Company recorded a $16.3 million write-off of capitalized software costs, previously included in construction-in-progress.
