It’s not clear whether the Woodruff gift is being paid all at once or spread out over several years. I can’t tell from the Emory press release. I doubt the Wall Street Journal computations accounted for this gift which wasn’t announced until 2 weeks before the WSJ published this article. Again, the Emory press release doesn’t say payment schedule for the gift.
It is noteworthy that the gift is being used in significant part to construct two new buildings, which would not generate the type of investment gain taxed under the endowment tax for those institutions that meet the $500,000/student threshold.
