Shareholder activist Carl Icahn has petitioned for a seat on Motorola's board, the company disclosed in its most recent proxy statement, filed with the Securities and Exchange Commission. The billionaire financier, now 71, holds (through affiliates) a 2.9 percent stake in the telecom equipment manufacturer, which is based in Schaumburg, Illinois.

The letter, addressed to Motorola shareholders, comes as shares have fallen to an all-time low of around $17. The stock price has been on a steady six-month decline due to disappointing profits and an announcement last month that first-quarter sales would fall more than $1 billion short of earlier projections.

"I had hoped that the existing board would have simply added me as a new member without the distraction of a proxy fight," Icahn wrote in the letter dated April 12. "However, I am willing to expend the time, effort, and money necessary to seek election through this proxy contest so that all of us will have a shareholder voice on the Motorola board."

In the letter, Icahn is pugnacious in his criticism of the current board's performance. "In my view, an engaged board of directors should have been able to help Motorola avoid the missteps that currently plague its business, or at least to have identified and addressed those problems earlier," he writes.

Icahn went on to outline his reasons for seeking a seat, as well as his fitness for the position. While he had previously encouraged buybacks, Icahn said in the letter that he now thinks stock repurchases should wait until after Motorola turns around its profit performance. He also pledged to scale back his involvement in other interests, and cut the number of boards he sits on to six, to make time for Motorola.

"The board is constantly looking at near- and long-term strategies for improving shareholder value," said spokesman Paul Alfieri. "Our board has been proactive in implementing changes when those changes would advance that objective."

Though Icahn's approach to shareholder activism has softened significantly since his days of targeting Texaco and RJR Nabisco, he has an established reputation as a corporate raider with no appetite for failure. Motorola has urged shareholders to withhold from any action until the 2007 shareholder meeting, which is set for May 7.
