BroadVision executives said it will also take an unspecified restructuring charge in the second quarter to cover the costs of laying off 325 employees, or roughly 15 percent of its staff.
It also said it absorbed an additional $4 million in charges in its fourth quarter, resulting in actual earnings of 1 cent a share in the quarter instead of the 2 cents a share it reported in January.
"Our first quarter results reflect economic uncertainties, which caused some customers to postpone major IT expenditures," said CEO Pehong Chen in a prepared release. "Given continuing concerns surrounding the economic and IT spending environments, we are taking decisive short-term actions intended to return the company to profitable operation as quickly as possible, including streamlining our organization and aggressively containing discretionary spending."
Last quarter, BroadVision missed analysts' estimates when it made a profit of $4.5 million, or 1 cent a share.
