(a)
It is unlawful to make or cause to be made any knowingly false or fraudulent statement, whether made orally or in writing, of any fact material to the determination of the premium, rate, or cost of any policy of workers’ compensation insurance issued or administered by the State Compensation Insurance Fund for the purpose of reducing the premium, rate, or cost of the insurance. Any person convicted of violating this subdivision shall be punished by imprisonment in a county jail for one year, or pursuant to subdivision (h) of Section 1170 of the Penal Code for two, three, or five years, or by a fine not exceeding fifty thousand dollars ($50,000), or double the value of the fraud, whichever is greater, or by both that imprisonment and fine.
(b)
Any person who violates subdivision (a) and who has a prior felony conviction of the offense set forth in that subdivision shall receive a two-year enhancement for each prior conviction in addition to the sentence provided in subdivision (a). The existence of any fact that would subject a person to a penalty enhancement shall be alleged in the information or indictment and either admitted by the defendant in open court, or found to be true by the jury trying the issue of guilt or by the court where guilt is established by plea of guilty or nolo contendere or by trial by the court sitting without a jury.
