Thereafter, the minimum amount for each succeeding year shall be determined by the Borough Solicitor during February of such year in the following manner: The minimum amount of the previous year shall be increased or decreased during each succeeding year by the amount of inflation or deflation that has taken place in the preceding year.

The index for determining the amount of inflation or deflation shall be the Consumer Price Index for Urban Wage Earners and Clerical Workers (including single workers) published by the Bureau of Labor Statistics, United States Department of Labor (1957-59 = 100) or, if the said Consumer Price Index be discontinued, then such consumer price index as the Borough Solicitor shall determine is the generally recognized successor thereto.
