October 19, 2018 CALIBRE Systems Incorporated Attn: General Counsel’s Office 6354 Walker Lane Suite 300 Alexandria, Virginia 22310-3252 Dear General Counsel of CALIBRE Systems Incorporated: The Project On Government Oversight (POGO) is creating a Department of Defense Revolving Door Database on its website (pogo.org), which compiles information from public resources regarding former senior Department of Defense officials and military officers who went on to work for government contractors, including CALIBRE Systems Incorporated, from 2008 to the present. The database is an attempt to track individuals when they leave the Department of Defense, and inclusion in the database doesn’t represent anything illegal or a violation of ethics rules. I have enclosed the findings relevant to CALIBRE Systems Incorporated and am requesting verification or refutation of the data from you. Any response would be greatly appreciated, as the accuracy of this information is in the best interest of all parties. When a precise start date was not publicly available POGO chose the first day of the month the employee said they began working for CALIBRE Systems Incorporated. POGO is also interested in any related ethics opinions issued for current or former CALIBRE Systems Incorporated personnel in compliance with the National Defense Authorization Act for Fiscal Year 2008, Public Law 110-181, Sec. 847 and certifications of compliance as required by Defense Federal Acquisition Regulation Supplement (DFARS) subpart 252.203-7005; 41 U.S.C. § 2105(c). Out of fairness to CALIBRE Systems Incorporated, please be assured that any response received by POGO will be posted on the website along with the data if you so choose. If you have any questions, I can be reached at (202) 347-1122 or msmithberger@pogo.org. Thank you for your time and consideration.
