Sociedad Quimica y Minera de Chile SA, or SQM, recommended that shareholders approve a final 2017 dividend of about US$1.63 per share, representing 100% of the company's net income of US$427.7 million for the year.

In comparison, the Chilean miner proposed a final dividend of about US$1.06 per share for 2016.

The company said March 28 that its interim dividend of US$1.21 per share will be deducted from the final amount, resulting in a balance of 41.97 U.S. cents per share.

SQM will seek shareholder approval at an April 27 meeting.
