The Boston Museum of Fine Arts, which took on a sizable amount of debt in recent years with the opening of two new wings (currently, $175 million of outstanding Series A-1 and A-2 variable-rate demand bonds that the institution has issued through the Massachusetts Health and Educational Facilities Authority), recently was affirmed by Moody's in its Aa2 rating, its third-highest rating for institutions. Those bonds reach maturity in 2037, but bond holders could cash in early, which could cause the museum considerable financial stress since its ability to quickly monetize assets is restricted by donors when they made gifts to the institution. Bond holders would be more apt to cash out early if the museum's credit rating and long-term forecast declines, so Moody's determination that the museum's outlook is stable is a matter of dollars and cents.
