With the LED market migrating from two-inch to four-inch substrates, much of the remaining two-inch demand comes from the mobile device market (…) GAAP loss per share in the third quarter was $0.53 and included certain non-cash charges, the majority of which were associated with changes made to the Company’s polishing platform in order to reduce product costs.”
