Credit Facility

On March 14, 2013, USEC amended its credit facility that was scheduled to mature on May 31, 2013. The amended revolving credit facility totals $110.0 million (including letters of credit of up to $50.0 million or $25.0 million upon cessation of enrichment at the Paducah GDP) and matures on September 30, 2013. The term loan under the credit facility was repaid in connection with the amendment.

Utilization of the credit facility at March 31, 2013 and December 31, 2012 follows:


	March 31,		December 31,
	2013		2012

Borrowings under the revolving credit facility	$	-	$	-
Term loan		-		83.2
Letters of credit		12.4		14.7
Available credit		67.6		87.1

As of March 31, 2013, USEC met all of the reserve provision and collateral requirements of the credit facility and was in compliance with all of the covenants.

The credit facility is secured by assets of USEC Inc. and its subsidiaries, excluding equity in, and assets of, subsidiaries created to carry out future commercial American Centrifuge activities. Borrowings under the credit facility are subject to limitations based on established percentages of eligible accounts receivable and USEC-owned inventory pledged as collateral to the lenders. The amended credit facility requires cash collateralization of letters of credit issued by the bank at 105%. Cash collateralization of $15.1 million as of March 31, 2013 is classified as restricted cash. Available credit reflects the levels of qualifying assets at the end of the previous month less any borrowings or letters of credit.

The credit facility is available to finance working capital needs and general corporate purposes. The credit facility imposes limitations and restrictions on USEC's ability to invest in the American Centrifuge project. With certain exceptions, all funds of USEC Inc. and its subsidiaries will be subject to full cash dominion, meaning that they will be swept on a daily basis into an account with the administrative agent and will be used to pay outstanding loans before they are available to USEC for use in its operations.

The credit facility contains various reserve provisions that reduce available borrowings under the facility periodically including a permanent availability block equal to $30.0 million. The other reserves under the revolving credit facility, such as availability reserves and borrowing base reserves, are customary for credit facilities of this type.

Convertible Senior Notes due 2014

Convertible senior notes amounted to $530.0 million as of March 31, 2013 and December 31, 2012. The convertible senior notes are due October 1, 2014. Interest of 3.0% is payable semi-annually in arrears on April 1 and October 1 of each year. The notes were not eligible for conversion to common stock as of March 31, 2013 or December 31, 2012.
