The 8.0% paid-in-kind (“PIK”) toggle notes (the “PIK Toggle Notes”) pay interest at a rate of 8.0% per annum. Interest is payable semi-annually in arrears based on a 360-day year consisting of twelve 30-day months. The principal amount is increased by any payment of interest in the form of PIK payments. The Company has the option to pay up to 5.5% per annum of interest due on the PIK Toggle Notes in the form of PIK payments. For the semi-annual interest periods ending March 31, 2016 and September 30, 2016, the Company has elected to pay interest in the form of PIK payments at 5.5% per annum. As such, interest for the semi-annual period ended March 31, 2016 was paid as $3.1 million in cash and $6.8 million in PIK payments, and the principal balance increased accordingly to $254.4 million. Financing costs for the issuance of the PIK Toggle Notes were deferred and are being amortized on a straight-line basis, which approximates the effective interest method, over the life of the PIK Toggle Notes.

The PIK Toggle Notes will mature on September 30, 2019. However, the maturity date can be extended to September 30, 2024 upon the satisfaction of certain funding conditions described in the Indenture relating to the funding, under binding agreements, of (i) the American Centrifuge project or (ii) the implementation and deployment of a National Security Train Program utilizing American Centrifuge technology.

The PIK Toggle Notes rank equally in right of payment with all existing and future unsubordinated indebtedness of the Company (other than the Issuer Senior Debt as defined below) and are senior in right of payment to all existing and future subordinated indebtedness of the Company.
