S&P Global Ratings assigned its 'AAA' long-term rating to the Massachusetts Institute of Technology's (MIT) taxable bonds, series E. In addition, S&P Global Ratings affirmed its 'AAA' and 'AAA/A-1+' long-term ratings on Massachusetts Institute of Technology's (MIT) existing debt, some of which was issued by the Massachusetts Development Finance Agency (formerly known as the Massachusetts Health and Educational Facilities Authority). The outlook, where applicable, is stable. The 'AAA' rating reflects our view of MIT's extremely strong enterprise profile, characterized by incredible demand for its programs, exceptional student quality, a geographically diverse student body, and impressive management and governance oversight. We assessed the college's financial profile as very strong, with a substantial endowment and a track record of excellent operating performance.
