The Hill - North Carolina's "bathroom bill" will cost the state more than $3.76 billion over the next dozen years, according to an Associated Press analysis.
The law, which requires that people use the bathroom that corresponds to the sex on their birth certificates, has already resulted in lost business.
Several artists have pulled out of concerts scheduled in North Carolina, and the NCAA avoided the state as a host site for its annual basketball tournament.
Bank of America CEO Brian Moynihan said he has spoken with business leaders who have decided to conduct projects in other states. "Companies are moving to other places because they don't face an issue that they face here," he told a World Affairs Council of Charlotte luncheon last month, according to the AP.
