Updated from 1:04 p.m. Shares of C-Cor Electronics ( CCBL) were among technology's losers Wednesday, falling 8.8% after the company cut its third-quarter forecast by a wide margin. The Internet services and products company now expects to post a loss of 34 cents to 38 cents a share on sales of $47 million to $49 million. Earnings projections include a $2.7 million charge for in-process research and development, and a $1.7 million charge for amortization of intangible assets, or 9 cents a share. In January, the company said it expected to post a third-quarter loss of 4 cents to a profit of 2 cents on sales of $70 million to $75 million. C-Cor blamed the shortfall on higher-than-expected purchase accounting adjustments to deferred revenue, which are related to its acquisition of nCube, and to customer orders late in the quarter that won't be recognized in time to be counted for the third quarter. C-Cor expects to release third-quarter results on April 21. Shares traded down 62 cents to $6.41. B.O.S.
