Ixia announced Wednesday it received a notice from Nasdaq Stock Market LLC on Tuesday that the computer network equipment manufacturer no longer complies with Nasdaq’s listing rules. The rule requires that companies must file all required periodic financial reports with the Securities and Exchange Commission. Ixia now has 60 calendar days, until January 18, to submit a plan to Nasdaq to regain compliance with the rules. Earlier this week, the Calabasas-based company announced it had delayed its quarterly report for the quarter ended Sept. 30 due to a review of financial information. The company conducted the review after the resignation of Victor Alston, the formerchief executive, who abruptly left in October over a falsified resume.
