From the perspective of headquarters, commitment to the parent is perceived as important, given the part that the PCN plays in transferring know-how and ‘the preferred way of doing things’ into the subsidiary. This helps to explain the preference for using headquarters’ standards in expatriate performance appraisal as a control mechanism. If the PCN is perceived to identify too closely with host-subsidiary concerns (the term ‘going native’ has, in the past, often been used to describe this perception), he or she may be recalled. Some MNEs will restrict the length of stay to no more than three years to contain the possibility of PCN identification with local concerns. Because of the importance given to the parent as role sender in performance appraisal, a PCN may elect to ignore role communication sent from the host-country stakeholders if they consider that performance appraisal is determined by how role behavior conforms to headquarters’ expectations. After all, the expatriate's career is with the parent firm, not the host subsidiary.
