The complaint alleges that Defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. Specifically, the complaint alleges that Defendants issued a series of materially false and misleading statements during the Class Period regarding the Company's financial performance. More specifically, Defendants failed to disclose that Aspen had improperly recognized revenue for certain software license and service agreement transactions entered into with certain alliance partners during the period 2000-2002, and that as a result the Company's revenues and earnings were materially overstated.

On October 27, 2004, Aspen announced that its Audit Committee had begun a review of accounting for certain software license and service agreement transactions. According to the Company, the review could lead to a restatement. Then on October 29, 2004, Aspen announced that federal prosecutors launched a probe into the Company's accounting practices from 2000 through 2002. The Company also received a subpoena from the U.S. Attorney's Office for the Southern District of New York requesting documents related to the transactions the Company entered into in those years.

If you bought Aspen securities between January 25, 2000 and October 29, 2004, inclusive, and would like to obtain information about the lawsuit, then you are invited to call (800) 495-1868 to speak with an advisor.
