A wiser board might have stopped Chris Mawe’s £400,000 share sale the morning before auditor quit

It is a rare for an auditor to quit the role at a London-listed FTSE 250 firm. So one might conclude it was merely unfortunate that Chris Mawe, the finance director at Ferrexpo, chose last Thursday morning to sell £400,000-worth of shares, just before events moved rapidly at the Swiss-based miner of iron ore in Ukraine. In the evening of the same day, Deloitte quit. On Friday morning, when the firm’s resignation was made public, Ferrexpo’s share price plunged by 28%.

The company had not received Deloitte’s letter of resignation at the time of the share sale, so there is – to be clear – no suggestion rules were broken. Even so, one has to ask if it was sensible for Mawe to sell last Thursday when so many unanswered questions hung in the air.
