Did You Know? The Mega-wealth Tucked Away in Endowments

Collectively, the endowments of 15 Massachusetts colleges in 2017 were $70 billion, greater than the GDP of Lithuania. And Massachusetts isn’t alone—the endowments of 15 California colleges totaled $55 billion, and 10 Texas colleges trailed not far behind at $52 billion. Those institutions, as well as others in the chart above, comprise part of an elite group of about 100 colleges that have endowments exceeding $1 billion.

In this case, however, “elite” is far from a dirty word. For fiscal year 2017, colleges with endowments over $1 billion had a five-year average annual return of 8.6 percent and a 10-year average annual return of 5 percent.

Interestingly, the colleges with the most similar return rates over both periods were those with endowments of less than $25 million, who experienced average returns of 8.1 percent over 5 years and 5 percent over 10 years. This may be explained by the fact that while colleges with endowments over $1 billion had the highest spending rates and invested in the most “alternative strategies” (like private equity), those with endowments of less than $25 million invested the most in domestic equities and fixed income securities (like Treasury bonds).

In short, the amount of an institution’s endowment appears to have much less of an impact on its return than the way in which it is invested—wealthier schools spend big and take more risks, while less-wealthy schools stick to safer investments.
