The good news for Grant Thornton is that they managed to take remedial actions related to their 2010 inspection report and addressed criticisms to the satisfaction of the PCAOB. Cheers!
The bad news is that the same cannot be said for their 2008 and 2009 reports.
The quality control remediation process is basically a way for audit firms to improve on areas the PCAOB identifies as needing improvement. According to this, Grant Thornton is still in need of a little improvement. Better luck next time, guys!
