Advances from customers included $20.6 million as of September 30, 2012 and $22.3 million as of December 31, 2011 for services to be provided to DOE or to be applied to existing receivables balances due from DOE in USEC's contract services segment. DOE funded this work through an arrangement whereby DOE transferred uranium to USEC between the fourth quarter of 2009 and the first quarter of 2011, which USEC immediately sold in the market.

Advances from customers as of September 30, 2012 include $43.1 million representing the balance of $87.7 million of funding to date from DOE under the RD&D program. DOE made the $87.7 million available by taking the disposal obligation for a specific quantity of depleted uranium from USEC, which enables USEC to release encumbered funds for investment in the American Centrifuge technology that USEC had otherwise committed to future depleted uranium disposition obligations. In the third quarter of 2012, surety bonds and related collateral deposits were reduced and USEC received cash of $55.6 million. The remaining $32.1 million of encumbered funds are reflected in other long-term assets as of September 30, 2012, and are expected to be received as cash in the fourth quarter of 2012 as the remaining surety bonds and related collateral deposits are reduced. As of September 30, 2012, USEC made qualifying American Centrifuge expenditures under the RD&D program of $55.7 million. DOE's pro-rata share of 80%, or $44.6 million, is recognized as other income in the nine months ended September 30, 2012.
