Sec. 225.4  Limitation on amount of earnings used to compute a PIA.

    Certain PIA's used by the Board are based on a combination of 
compensation and wages, while other PIA's used by the Board are based 
solely on either compensation or wages. For purposes of crediting 
earnings when computing any PIA, compensation is always treated as 
wages. Regardless of whether a PIA is based on a combination of 
compensation and wages or exclusively on either compensation or wages, 
the total earnings for each year used in computing a PIA cannot be 
higher than the maximum social security earnings creditable in that year 
under sections 209(a) and 211(b) of the Social Security Act. The various 
PIA's used by the Board are described in subparts B and C of this part.
