Since 1948, SSA has provided information from its earnings records to private pension
plan administrators. Detailed annual earnings amounts of participants in the specific
pension plan are used by the pension plan to determine the worker's eligibility and
pension amount. In plans to which more than one employer contributes, the earnings
information may also be used to allocate pension costs among the employers.

earnings history is provided to pension plans.
