However, the facts plainly show that this is not even remotely true. Let us examine how, over the last decade, shareholders have benefited as a result of my taking sizeable positions and pressing for performance improvements. During this period, we were strong activists in well over 20 companies with an equity capitalization of between $500 million and $20 billion in which we purchased a large amount of stock. If investors had purchased these stocks when we did and sold when we did, even with factoring in some losing investments, they would have realized a net annualized return of 23.44 percent -- compared to a return of 1 percent if they made the same investment over the same time period in the S&P 500 Index. Additionally, the stock value of these companies increased by approximately $44 billion over the same period, obviously benefiting all shareholders. These companies included such well-known names as Biogen, Genzyme, Blockbuster, CIT, Korean Tobacco, Kerr-McGee, ImClone and Amylin. Furthermore, we also invested in a number of distressed bonds during this period and were actively involved in restructuring the indebted companies. Although all bondholders greatly benefited from our activities, these results were not factored into the above calculations of net return. The article in Sunday's Post completely omitted the great benefits to shareholders outlined above. Instead it focused on four examples where I allegedly took advantage of shareholders: * DYNEGY: Recently we opposed a $4.50 per-share bid for Dynegy made by Blackstone. Seneca Capital, a New York hedge fund, asserted that the auction process awarding Blackstone the company was totally unfair and made it almost impossible for any other bids to materialize -- because Blackstone would have a right of first refusal. Furthermore, Blackstone would receive a $50 million breakup fee if another bid was accepted. I told shareholders that they should vote against Blackstone's offer and that a new and fair auction process should be initiated. In the new process, I promised to make a "stalking horse bid" with a breakup fee of $35 million less than Blackstone's breakup fee with no right of first refusal. In addition, I offered to pay 22 percent more than Blackstone's original bid. For some reason that I cannot fathom, The Post is saying I somehow took advantage of Dynegy by keeping my promise and making a higher offer. * BLOCKBUSTER: Even more ridiculous is a lawsuit that The Post quotes, stating that soon after I left the board of Blockbuster, I purchased Blockbuster bonds on the cheap, knowing it would go into bankruptcy. With all due respect, I do not believe The Post should be quoting unfounded malicious allegations filed in an absurd complaint. I left the Blockbuster board in January and did not purchase Blockbuster bonds until August, when it was already publicly known that Blockbuster might go bankrupt, since they had entered into "forbearance agreements" with creditors (copies of which were filed with the SEC) because they could not make the required interest payments. * LIONSGATE: The specious allegations regarding supposed secret plans involving MGM and Lionsgate are a complete fabrication, invented to justify meritless litigation by Lionsgate to throw roadblocks in the way of our campaign to improve the company's dismal performance. Accordingly, we have filed a motion, still pending, to dismiss Lionsgate's complaint. * XO COMMUNICATIONS: The Post has repeated certain negative statements made by Geoffrey Raynor, a shareholder of XO, a company which I control. He purchased XO approximately seven years ago at $5 per share and obviously has a large loss. In fact, since the time of his purchase, I have had to invest substantial additional funds into XO in order to keep its business alive, during a period in which small telecommunication companies have fared very badly. As a result, I now have just under $l billion of preferred stock. Raynor, like other large holders, was offered opportunities to invest with me. He declined to do so, choosing instead to bring lawsuits against me rather than face up to the fact that he has made a very poor investment. In recent years, Raynor has also brought numerous lawsuits against others in connection with other investments he has made. Raynor also argues that I could have sold the company. This is entirely false. We hired investment bankers and tried for two years to sell and never got a firm cash offer. To sum up, I believe it is a truism that "activism," if done properly, enhances value for all shareholders. The reason activism is so profitable is not because of the genius of activists but, sadly, because many companies in our country have managers that are not held accountable and are often doing a poor job. Additionally, many companies would be more efficient if they were consolidated with other synergistic companies. However, too many managements and boards would rather entrench themselves than take these actions. Unfortunately, if we do not do something soon about increasing the efficiencies of our corporations, our country will continue to lose its edge in competing in the global economy and unemployment will continue to grow.
