*GTIL reports global results in US dollars (USD). However, most member firms do not use USD as their local reporting currency so current year results are calculated using the prior year USD rate to remove the impact of currency fluctuations of the current year. This is referenced as ‘constant currency’. Growth in constant currency are also reported on a pro rata basis adjusted for practice disposals by member firms in the network. This enables for a like-for-like comparison between reporting periods.
