was invested primarily in money market funds, municipal auction rate certificates and commercial paper. Any
adverse changes in interest rates or securities prices may decrease the value of our short-term investments and
operating results.
We are exposed to market risk from changes in interest rates on our outstanding cash and cash equivalents,
investments and bank debt. On our cash equivalents and investments we are exposed to changes in interest rates,
particularly short-term interest rates. With regards to our debt, the level of our actual average monthly
borrowings determines the interest rates we pay on borrowings. The interest rate will be between prime and
prime plus 0.50% or LIBOR plus 1.75% and LIBOR plus 2.50%. Prime rate is the rate publicly announced by
Bank of America as its prime rate. The interest cost of our bank debt is affected by changes in either prime rate
or LIBOR. We had no outstanding debt at December 31, 2006 and December 31, 2005, or any time during those
years.

Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this annual report on Form 10-K, we evaluated the effectiveness of
the design and operation of our disclosure controls and procedures, or disclosure controls. This controls
evaluation was performed under the supervision and with the participation of management, including our Chief
Executive Officer, or CEO and Chief Financial Officer or CFO. Disclosure controls are controls and procedures
designed to reasonably assure that information required to be disclosed in our reports filed under the Exchange
Act, such as this report, is recorded, processed, summarized and reported within the time periods specified in the
USEC’s rules and forms. Disclosure controls are also designed to reasonably assure that such information is
accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely
decisions regarding required disclosure.
The evaluation of our disclosure controls included a review of the controls’ objectives and design, our
implementation of the controls and the effect of the controls on the information generated for use in this report.
In the course of the controls evaluation, we reviewed and identified data errors and control problems and sought
to confirm that appropriate corrective actions, including process improvements, were being undertaken. This type
of evaluation is performed on a quarterly basis so that the conclusions of management, including our CEO and
CFO, concerning the effectiveness of the disclosure controls can be reported in our periodic reports on Form
10-Q and Form 10-K.
Based upon the controls evaluation, our CEO and CFO have concluded that our disclosure controls were
effective as of December 31, 2006.
