During an audit of accounting of services at PostBus Switzerland Ltd, the Federal Office of Transport (FOT) found evidence of accounting practices that do not comply with the law. In view of these audit findings, Swiss Post initiated enquiries by independent experts in November 2017 concerning financial reporting under subsidy law at the Swiss Post subsidiary PostBus Switzerland Ltd. Both the FOT and Swiss Post have concluded that PostBus Switzerland Ltd used accounting practices that do not comply with subsidy law in the period from 2007 to 2015 and, as a result, received excessively high compensation for the provision of public transport services. Swiss Post management has already undertaken relevant measures, and PostBus will reimburse the Confederation and the cantons in full for the unlawful compensatory payments.
