Convertible Senior Notes due October 1, 2014

The balance sheet carrying value of USEC’s convertible senior notes was $530.0 million as of December 31, 2013 and December 31, 2012. The convertible senior notes, issued in September 2007, bear interest at a rate of 3.0% per annum payable semi-annually in arrears on April 1 and October 1 of each year. The convertible senior notes are due October 1, 2014, and are classified as a current liability as of December 31, 2013. USEC paid underwriting discounts and offering expenses of $14.3 million in 2007, and these costs were deferred and are being amortized using the effective interest rate method over the life of the convertible notes. Under our proposed Plan, the convertible notes will be restructured. Refer to "Chapter 11 Filing" in Note 1.

The notes are senior unsecured obligations and rank equally with all existing and future senior unsecured debt of USEC Inc. and senior to all subordinated debt of USEC Inc. The notes are structurally subordinated to all existing and future liabilities of subsidiaries of USEC Inc. and will be effectively subordinated to existing and future secured indebtedness of USEC Inc. to the extent of the value of the collateral. The notes were not eligible for conversion to common stock as of December 31, 2013 or December 31, 2012.

Under the terms of USEC's convertible notes, a "fundamental change" is triggered if USEC's shares of common stock are not listed for trading on any of the NYSE, the American Stock Exchange (now NYSE-MKT), the NASDAQ Global Market or the NASDAQ Global Select Market, and the holders of the notes can require USEC to repurchase the notes at par for cash. However, as a result of the Chapter 11 filing, any actions to enforce such repurchase right or to otherwise exercise rights under the notes are stayed.
