There was a doozy of a footnote in Nokia’s earnings report on Thursday.
Since signing its deal to go with Windows Phone in February 2011, Nokia has been getting $250 million per quarter in “platform support payments” from Microsoft. Nokia also pays Microsoft an unspecified amount of royalties for using Windows Phone. It varies based on the amount of phones Nokia ships, and there are also minimum commitments. Over the life of the deal, Nokia and Microsoft have said there will be billions of dollars going between the two companies.
