PBGC preliminary estimate of ERISA liability
PBGC preliminary estimate of ERISA liability
After receiving the Company’s notification of the transition of employees at the Portsmouth GDP in 2011, the PBGC staff at that time informally advised Enrichment Corp. of its preliminary view that the Portsmouth GDP transition was a cessation of operations that triggered liability under ERISA Section 4062(e) and that its preliminary estimate was that the ERISA Section 4062(e) liability (computed taking into account the plan’s underfunding on a “termination basis,” which amount differs from that computed for GAAP purposes) for the Portsmouth GDP transition was approximately $130 million.

Separative Work Units [Member]
Separative Work Units [Member]
Separative Work Units (SWU) [Member] - SWU is a standard unit of measurement that represents the effort required to transform a given amount of natural uranium into two components: enriched uranium having a higher percentage of the uranium-235 isotope (“U235”) and depleted uranium having a lower percentage of U235. The SWU contained in LEU is calculated using an industry standard formula based on the physics of enrichment. The amount of enrichment deemed to be contained in LEU under this formula is commonly referred to as its SWU component and the quantity of natural uranium used in the production of LEU under this formula is referred to as its uranium component.
