Along the topic of why US hesitates to adopt IFRS, The textbook states the US is “disinclined to give up the GAAP standards over domestic issuers to an international standard-setting body headquartered in London.” Would this be an altered or a different scenario if headquarters were outside of London?

New York State Society of Certified Public Accountants released their comments in 2009 voicing their concerns regarding IFRS adoption. Nearly over a decade later, in present day, would some accountants disagree with their colleagues that voiced their concerns back in 2009? Is the SEC’s plan for adoption still lacking sufficient detail?
