SQM Salar has filed seven tax claims against the SII. The amount paid included US$59.5 million in over-assessed amounts, US$818.0 million in disputed taxes (net of the corporate income tax impact), and US$108.8 million in interest and penalties.

Although this ruling by the Santiago Court of Appeals does not affect the other claims filed by SQM Salar against the SII and is still subject to appeal by SQM Salar, it prompted a review of the accounting treatment of the tax claims by the Company’s Board of Directors.
