Huntsman said its second-quarter profit skyrocketed as a hefty legal settlement offset a steep drop in sales. For the period ended June 30, the company reported net income of $406 million compared with $24 million in the year-earlier period. The results were bolstered by a gain of $1.7 billion from a settlement earlier in the year with Deutsche Bank and Credit Suisse Group. Sales fell 36 % to $1.87 billion.
