S&P Global Ratings assigned its 'AA+' long-term rating to the Massachusetts Housing Finance Agency's (MassHousing) $124.3 million series 233, 234, and 235 single-family housing revenue bonds (SFHRBs) within its SFHRB program. At the same time, S&P Global Ratings affirmed its 'AA+', 'AA+/A-1+', and 'AA+/A-1' ratings on previously issued debt within MassHousing's SFHRB program. The outlook, where applicable, is stable. Bonds issued within the SFHRB program are special obligations of MassHousing, secured solely by certain revenue and funds established under this program for their security and payment. These bonds are on parity with all other obligations under this program. The 'AA+/A-1+' and 'AA+/A-1' dual ratings reflect the long-term rating on previously issued debt as well as our view of liquidity support
