​ On March 7, 2023, the Company determined that it had been a victim of a complex criminal scheme, which resulted in fraudulently-induced outbound wire transfers to a third-party account. As a result of the event, the Company incurred a loss of approximately $3.0 million related to the amount of the unrecovered funds. Any amount of this loss expected to be reimbursed to the Company from its insurance policy is not expected to be material. The Company retained specialized legal counsel and a cybersecurity services firm to assist in an independent forensic investigation of the incident and the efforts to recover the funds. As a result, the Company incurred legal, audit and other professional fees in the aggregate amount of $0.2 million related to this event. The total amount of the fraud loss and the professional fees, approximately $3.2 million, is included in other loss in the condensed consolidated statements of earnings for the three months ended April 30, 2023.
