text: 4. SEPARATELY DISCLOSED ITEMS
text: The Group has disclosed underlying EBITDA1 and underlying profit after tax, referring to the Group’s trading results adjusted for certain transactions during the year that are not representative of the Group’s regular business activities. The Group considers that these transactions are of such significance to understanding the ongoing results of the Group that the Group has elected to separately identify these transactions to determine an ongoing result to enable a 'like-for-like' comparison. These items are described as 'separately disclosed items' throughout this Financial Report.
text: Transaction costs related to the acquisition of Sigma Systems (2018: acquisition of Enoro)
text: Transaction costs of $2,063,000 were incurred in relation to the acquisition of the Sigma Systems group of entities (Sigma).

These costs were included with 'Other Expenses' in the Group’s consolidated statement of comprehensive income in the prior year.
text: Onerous lease provision
text: The Group recognised a provision on future lease payments for one of our offices in the Americas, as the non-cancellable future payments in the lease contract are expected to exceed the benefits from keeping the office over the remainder of the lease term. The Group has separately identified these costs because it is not in the normal course of business activities. These costs are included with 'Property and Operating Rental Expenses' in the Group’s consolidated statement of comprehensive income.
text: Restructuring costs incurred in Sigma Systems
text: Included in Sigma’s results for June are $72,000 of restructuring costs related to certain redundancy payments post-acquisition. These costs are included with 'Employee Benefit Expenses' in the Group’s consolidated statement of comprehensive income.
