IV.  Regulatory Flexibility Act

DoD certifies that this final rule will not have significant economic impact on a substantial number of small entities within the meaning for the Regulatory Flexibility Act, 5 U.S.C. 601, et seq., because major systems or subsystems are generally not developed by small businesses. The rule only applies in the limited circumstances that there is a challenge to a use or release restriction for a major system or subsystem that the contractor or subcontractor claims was developed exclusively at private expense.
