When looking at our differentiated products, we have made good progress in fingerprint sensor technology and CMOS-MEMS technology, which are both now in production.

We are also excited to announce that we have secured some used equipment for our Shenzhen fab, and we target 10-thousand-wafers-per-month capacity installed in Shenzhen by the end of this year and production in 2015.

We have improved our profitability and, as is reflected in our guidance, we believe we are positioned for a recovery in the second quarter, and we continue to be optimistic about the second half of this year."
