We have limited our review of your Forms 10-K to disclosures relating to your contacts with countries that have been identified as state sponsors of terrorism, and will make no further review of the Forms 10-K. Our review with respect to this issue does not preclude further review by the Assistant Director group with respect to other issues. At this juncture, we are asking you to provide us with supplemental information, so that we may better understand your disclosure. Please be as detailed as necessary in your response. After reviewing this information, we may or may not raise additional comments. Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filings. We look forward to working with you in these respects. We welcome any questions you may have about our comment or on any other aspect of our review. Feel free to call us at the telephone number listed at the end of this letter. General - We note your March 17, 2005 response to our letter dated December 28, 2004. While your letter makes clear that you considered qualitative factors in evaluating the materiality to your business and your security holders of the fact that, under the Agreement, your territory includes North Korea, it does not identify the qualitative factors you considered. Please advise us of the consideration you gave to factors such as risk to the Company`s reputation, and risk of possible corresponding negative impact on your share value, by virtue of the fact that the Agreement specifically contemplates that you will have contacts with a country identified as a state sponsor of terrorism and subject to U.S. economic sanctions. In this regard, please note that future evaluations of the materiality of the Agreement, and of any contacts you may have with North Korea pursuant to the Agreement, also should include careful consideration of these specific types of qualitative factors. Closing Please understand that we may have additional comments after we review your response to our comment. Please contact me at (202) 942- 7817 if you have any questions about the comment or our review. 								Sincerely, 								Cecilia D.
