The reasonableness" inquiry turns on a number of factors [see Restatement S 403(2, supra p. 759]. ** * The activity relevant to the counts at issue here took place primarily in the UnitedKingdom, and the defendants in these counts are British corporations and British subjects having their principal place of business or residence outside the United States. Great Britain has established a comprehensive regulatory scheme governing the London reinsurance markets, and clearly has a heavy "interest in regulating the activity," id., S 403(2)g). * ** Finally, s 2(b) of the MeCarran-Ferguson Act allows state regulatory statutes to override the Sherman Act in the insurance field, subject only to the narrow "'boycott" exception set forth in S 3(b)--suggesting that "the importance of regulation to the [United States]," Restatement (Third) $ 403(2/c), is slight. Considering these factors, I think it unimaginable that an assertion of legislative jurisdiction by the United States would be considered reasonable, and therefore it is inappropriate to assume, in the absence of statutory indication to the contrary, that Congress made such an assertion.
