Constant-currency basis amounts are calculated using the average foreign currency exchange rates for the comparable period in the prior year and applied to the current period. As an example, we calculate royalty revenues from China Dungeon&Fighter by applying the same CNY/USD, USD/KRW and KRW/JPY exchange rates from last year's same fiscal quarter. 4 Year-over-year growth on a constant currency basis 2021 NEXON Co., Ltd.
