In November 2017 the Financial Reporting Council (FRC) announced an investigation into the financial statements for the year ended 31 March 2016. This led to the disclosure in the Annual Report for 2017 that there had been errors in the impairment testing of healthcare goodwill and that, if certain judgements had instead been treated as errors, the amount of the prior year adjustment disclosed in the 2016 results would have increased by £44.0 million. This disclosure had addressed the FRC's concerns.
