The company now expects sales to decline 1 percent to 2 percent from the first quarter of 2008, implying revenue between $692.5 million and $685.5 million. Previously, the company expected sales to rise between 1 percent and 3 percent, to a range of $706.5 million to $720.5 million.
Analysts polled by Thomson Financial anticipate revenue of $710.8 million, on average.
