Perle has served as a Director of Hollinger International since June 1994. He is also Co-Chairman of Hollinger Digital Inc. and a Director of Jerusalem Post, both of which are subsidiaries of the company. He has served as a director of GeoBiotics. On August 31, 2004, a special committee of the Board of Directors investigating the alleged misconduct of the controlling shareholders of Hollinger International submitted the 512-page Breeden Report to the U.S. Securities and Exchange Commission (SEC). In the report, Perle is singled out as having breached his fiduciary responsibilities as a company director by authorizing several controversial transactions which diverted the company's net profit from the shareholders to the accounts of various executives. Perle received over $3 million in bonuses on top of his salary, bringing the total to $5.4 million, and the investigating committee called for him to return the money.
