I don't think anyone who has posted here understands why what they're saying means what it means.
Specifically, Nintendo says they have the Pokemon Company on their balance sheet under the equity ownership accounting method. when you do that, that means that Nintendo can't actually recognize the revenue from Pokemon Company directly under N's income statement because it is not their income. Instead Pokemon company will hold said cash on their books, so that Nintendo doesn't have to then pay taxes on the dividends received from Pokemon a Company by monetizing it. This way their investment grows in value but with no tax implications.
This doesn't mean that Pokemon company is not making bank on Pokemon Go, they probably are, it just means that the revenue will largely stay on Pokemon Company's books.
I think there is like some deferred tax liability stuff you will see on N's books... But I can't remember explicitly.
