(Changes in presentation of interim condensed consolidated statement of income)
In the interim condensed consolidated statement of income, the Company had presented the "Operating income (loss)" which classified the revenue and expense as those from operating activities and those from other activities until the previous fiscal year. However, since it became difficult to continuously adopt the previous method of presentation due to the varying earning activities of the Group, the Company changed its method to present "Revenue" and classification breakdown of "Expense" without presenting "Operating income (loss)". Accordingly, the interim condensed consolidated statement of income for the six months ended September 30, 2014 is revised in order to conform to the current year presentation.
