The New York Times had an article by William D Cohan (May 12th, 2017 - https://www.nytimes.com/2017/05/12/business/dealbook/a-little-known-accounting-change-could-have-a-big-impact.html) about a change to GAAP.
Again, those who create GAAP (this time a new (updated) FASB 2016-01) calculated the net gain to the public CPA firm's coffers before their core constituency: investors, creditors and the general public.
The new rule will require investments in other companies less than 20% be valued at market. Not annually, but quarterly.
Needless to say many of these investments are difficult to value, but think of the cost to the companies? Do it yourself or go out and pay someone else (sic: public CPA firms and speciality firms).
What do you think?
