The Office of the Inspector General (OIG) for the Commodity Futures Trading Commission has issued a report summarizing its investigation into the CFTC's cost-benefit analyses for four rulemakings promulgated under the Dodd-Frank Wall Street Reform and Consumer Protection Act. The OIG investigation, which was conducted at the request of Reps. Frank Lucas (R-OK) and K. Michael Conway (R-TX), reviewed how the CFTC formulated its cost-benefit analyses for its rulemakings regarding (1) definitions of "swap dealer," "major swap participant" and other key terms from Title VII of the Dodd-Frank Act; (2) confirmation, portfolio reconciliation and compression requirements for swap dealers and major swap participants; (3) core principles for designated contract markets; and (4) duties of swap dealers and major swap participants.
