Third quarter 2007 revenue was $154.6 million, a decrease of less than 2 percent sequentially and 3 percent compared to the third quarter of 2006. Revenue by end market during the third quarter was: -- Automotive -- $44.0 million or 28 percent of total revenue, down 1 percent sequentially due to a slower European summer season, but up 13 percent year over year; -- Medical -- $21.4 million or 14% of total revenue, down 16 percent sequentially and 24 percent year over year due to the expected weakness in the implantable and glucose metering sub-markets; -- Industrial -- $39.3 million or 25 percent of total revenue, up 2 percent sequentially due to strength in bookings, especially in the security market, but down 6 percent year over year; -- Mil/Aero -- $11.7 million or 8 percent of total revenue, down 6 percent sequentially but up 11 percent year over year due to normal third quarter seasonality; -- Communications and Computing -- $12.4 million or 8 percent and $15.8 million or 10 percent of total revenue, respectively, up over 5 percent sequentially in each market due to a rebound in overall communications and computing demand; -- Consumer -- $10.0 million or 7 percent of total revenue, up 9 percent due primarily to new product introductions.
