Colleges across the nation are scrambling to close deep budget holes and some have been pushed to the brink of collapse after the coronavirus outbreak triggered financial losses that could total more than $100 million at some institutions. Scores of colleges say they’re taking heavy hits as they refund money to students for housing, dining and parking after campuses closed last month. Many schools are losing millions more in ticket sales after athletic seasons were cut short, and some say huge shares of their reserves have been wiped out amid wild swings in the stock market.
