In a similar vein, a GAO report in 2014 determined that the market expectation of bailouts for the largest "too big to fail" banks had been largely eliminated by the reforms. That was determined by various methods, especially by comparing the funding cost of the biggest banks with smaller banks that are subject to ordinary FDIC resolution. That differential, which had been large in the crisis, had been reduced to roughly zero by the advance of reform, but the GAO also cautioned that the results should be interpreted with caution.
