Staffing division revenue does not include , and historically has not included , any revenue from nuclear engineering activities . Assystem's consolidated revenue is therefore now split out between " Nuclear " and " ET & I ” . However , in order to facilitate comparisons with prior periods , revenue figures for the Staffing division will be referred to on an ancillary basis in Assystem's revenue releases published during 2021 . In addition , the Group's segment information ( particularly relating to EBITA ) will henceforth be separated out into information related to operational activities , presented in a segment called " Assystem Operations " , and information related to holding activities , presented in a segment called " Holding company " .
