Foreign pensions that are based entirely on nonwork factors do not cause the WEP to
apply in the computation of a regular (non-Totalization) primary insurance amount
(PIA). Foreign pensions that are based on work or a combination of work and nonwork
factors may cause the WEP to apply. However, when a foreign pension is based on a
combination of work and nonwork factors, only that portion of the foreign pension
attributable to work will be considered for purposes of applying the guarantee provision
of the WEP.
