Iowa Code § 553.13
In addition to suit under section 553.12, the state may bring suit to assess a civil penalty against an enterprise whose conduct is prohibited under this chapter. The suit may be tried to the jury and the civil penalty provided for in this section shall be imposed by the court. The civil penalty assessed shall not exceed ten percent of the total value of the specific commodities by their brand, make, and size or of services either of which were the subject of the prohibited conduct sold in the relevant market in this state by the enterprise in each year in which this conduct occurred, but this penalty shall not exceed one hundred fifty thousand dollars. In computing this penalty, only the four most recent years in which the prohibited conduct occurred, as of commencement of suit under this section, shall be used in the computation.
