MURRAY HILL, N.J. (AP) – Telecom and networking equipment maker Alcatel-Lucent said Thursday that a computer disk containing personal information about Lucent employees, retirees and their dependents was lost.

The disk was prepared by Hewitt Associates for delivery by UPS to Aon Corp., another vendor, and was lost or stolen some time between April 5 and May 3.

The disk included Lucent employees’ names, addresses, Social Security numbers, birth dates and salary information.

The company said the disk did not include customer information.

‘We recognize that we have a responsibility to carefully protect this type of information and deeply regret this loss,’ said Frank D’Amelio, chief administrative officer for Alcatel-Lucent.

Shares of Alcatel-Lucent were trading at $13.31 in the after-hours session, up a penny from Thursday’s closing price of $13.30.
