The CPRP is an active defined-benefit pension administered by United Airlines that offers both lump-sum and annuity distribution options, with lump-sum amounts influenced by current interest rates. The PBGC benefit derives from United’s legacy A-Plan, which was terminated in 2004, and is now administered by the federal PBGC — a government corporation that insures private pension plans. Unlike the CPRP, the PBGC provides no lump-sum option; only annuity distributions are available, paid at benefit levels established under the plan’s termination priority categories. Coordinating both income streams is an important part of building a comprehensive retirement income plan.
