Ixia Chief Executive Bethany Mayer rang the closing bell on Monday at the Nasdaq in New York City. The appearance of the Calabasas developer of security and network-performance software at the Nasdaq comes after a year of stability in which the company straightened out its financial reporting and hired Mayer as new chief executive. Ixia had fallen behind with quarterly reporting after a review of its financials following the departure in October 2013 of then-chief executive Walt Alston, who resigned over false information in his resume. The company then reviewed its financials, leading to further delays, and it faced delisting from the Nasdaq until it become current in September of last year, a couple of weeks after Mayer was hired. Shares closed unchanged at $14.89.
