(1) Approximately $17 million of the $42.8 million aggregate future minimum rental commitments at December 31, 2018 relates to Kronos’ Leverkusen facility lease discussed above. The minimum commitment amounts for such lease included in the table above for each year through the 2050 expiration of the lease are based upon the current annual rental rate as of December 31, 2018. As discussed above, any change in the rent is based solely on negotiations between Bayer and Kronos, and any such change in the rent was deemed “contingent rentals” under prior GAAP and was excluded from the future minimum lease payments disclosed above.
