As at December 31, 2018, we had total provisions of $3,436,000 (2017 - $7,250,000) for supplies inventory that we no longer expect to utilize. Following the formation of our Puna Operations in 2017, which extended the operating life of the Pirquitas plant, we partially reversed our existing provision against supplies inventory by $6,342,000.
