Microsoft announced that it expected the acquisition is to be accretive to non-GAAP earnings within two years. What does non-GAAP mean in this case? In other words: what major expense is excluded?

Please research FASB and SEC pronouncements on this issue, possibly including but not limited to Anders (2017), Golden (2017) and SEC (2018).
