Personnel expenses increased by CHF 5.4 million or 1.2 per cent from the previous year to CHF 447.8 million. Disregarding the effects of changes to the group of consolidated companies, the increase in personnel expenses was CHF 18.9 million. An important reason for the increase in personnel expenses is the reduction in compensation for short-time work which the TX Group claimed in the reporting year. The compensation for short-time work was CHF 7.3 million in 2021 (previous year: CHF 21.2 million), while the subsidy from the welfare fund to cover shortfalls for employees short-time work was CHF 1.3 million compared with CHF 4.4 million the previous year. The expenses associated with the profit share participation programme also increased by CHF 7.7 million. By contrast, employee benefit expenses as per IAS 19 decreased by CHF 11.0 million compared with the previous year, which is attributable in particular to TX Group welfare fund covering the costs in the previous year of funding shortfalls due to short-time work and social plan benefits. Disregarding one-off effects and the change to the group of consolidated companies, current personnel expenses were up by around CHF 6.8 million compared with the previous year.
