Israel Chemicals Ltd., the fertilizer maker that listed shares in the U.S. last week, headed for the biggest decline in a year after Israel Corp. sold part of its stake at below market value. Israel Chemicals declined 4.4 percent to 26.56 shekels ($7.22) at the close in Tel Aviv, the steepest retreat since October 2013. Israel Corp. slid 3.7 percent to 2,075 shekels, after the holding company sold more than 60 million shares of its subsidiary at a price of $7 in a secondary offering as ICL listed on the New York Stock Exchange. That's a 7 percent discount to the closing price in Tel Aviv on Sept. 23.
