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.
