Tobacco companies involved in the 1998 landmark settlement with states over tobacco-related health care costs transferred more than $71 million last week in their annual payment to Iowa, Attorney General Tom Miller said Friday. The payment includes a $6 million tobacco arbitration judgment from September.  In that case, cigarette manufacturers claimed that Iowa did not diligently enforce its tobacco statutes in 2003, as required under the settlement.  A unanimous three-judge panel sided with Iowa. The state has received more than $960 million in payments since 1999 through the agreement, which also created a broad array of restrictions on the advertising, marketing and promotion of cigarettes.
