(a) The contributions of an employer and the contributions of its employees shall be transmitted to the administrator as soon as practicable after the close of the payroll period for which the contributions are made. Subject to (c) of this section, if an employer is delinquent in transferring the contributions for more than 15 days, interest shall be assessed on the outstanding contributions at one and one-half times the most recent actuarially determined rate of earnings for the retirement plan from the date that the contributions were originally due.
(b) If contributions are not submitted within the prescribed time limit, the amount of contributions and interest due may be claimed by the administrator from any agency of the state or political subdivision that has in its possession funds of the employer or that is authorized to disburse funds to the employer that are not restricted by statute or appropriation to a specific purpose. The amount claimed shall be certified by the administrator as sufficient to pay the contributions and interest due from the employer. The agency shall submit the amount claimed, or the amount of funds of the employer subject to the administrator's claim that are in the agency's possession, whichever is less, to the administrator for deposit in the retirement fund and the Alaska retiree health care trust.
(c) If an employer delinquent in transferring a contribution is a municipality in which the population decreased by more than 25 percent between 2000 and 2010, according to the decennial census conducted by the United States Bureau of the Census, the administrator may assess interest on the outstanding contribution at a rate less than the rate required in (a) of this section.
