PriceWaterhouseCoopers state that accountants in 283 countries implement IFRS as of June 2014. Here is the reference: http://www.pwc.com/en_US/us/issues/ifrs-reporting/publications/assets/pwc-ifrs-by-country-2014.pdf

That means that all accountants in the world implement the IASB's definition, namely 100% cumulative inflation over three years. 

PriceWaterhouseCoopers is a very reliable source. The PWC source is thus a very reliable source of the prevalence of the IASB's definition. The fact that all governments follow the IASB´s definition is thus now reliably referenced as well as relevant. I maintain my position that I can thus remove the said sentence as a reliable source has now been found that all accountants and all governments in the world follow the IASB´s definition. That is overwhelming proof that the IASB´s definition is the prevalent defintion. 195.23.41.216
