That OTS was the primary regulator of AIG has been described as "nonsense" and compared to "the super-heavyweight of the world going up against the 65 lb, 13-year-old, class weakling". AIG operates in 130 countries. The OTS had a small division that monitored derivatives including the credit default swaps at AIG. After a dispute with Goldman Sachs in 2007 over the value of the credit default swaps, the OTS did not initiate formal enforcement action, but "periodically raised concerns with AIG managers". Other sources of concern were the three credit rating agencies and AIG's auditor PricewaterhouseCoopers. In March 2008, after AIG disclosed valuation problems, the OTS sent a letter to AIG requesting a "corrective action plan" in 30 days. The division overseeing AIG Financial Products was "quietly disbanded" and AIG missed their deadline.
