Section 54.713 - Contributors' failure to report or to contribute(a) A contributor that fails to file a Telecommunications Reporting Worksheet and subsequently is billed by the Administrator shall pay the amount for which it is billed. The Administrator may bill a contributor a separate assessment for reasonable costs incurred because of that contributor's filing of an untruthful or inaccurate Telecommunications Reporting Worksheet, failure to file the Telecommunications Reporting Worksheet, or late payment of contributions. Failure to file the Telecommunications Reporting Worksheet or to submit required quarterly contributions may subject the contributor to the enforcement provisions of the Act and any other applicable law. The Administrator shall advise the Commission of any enforcement issues that arise and provide any suggested response. Once a contributor complies with the Telecommunications Reporting Worksheet filing requirements, the Administrator may refund any overpayments made by the contributor, less any fees, interest, or costs.(b) If a universal service fund contributor fails to make full payment on or before the date due of the monthly amount established by the contributor's applicable Form 499-A or Form 499-Q, or the monthly invoice provided by the Administrator, the payment is delinquent. All such delinquent amounts shall incur from the date of delinquency, and until all charges and costs are paid in full, interest at the rate equal to the U.S. prime rate (in effect on the date of the delinquency) plus 3.5 percent, as well as administrative charges of collection and/or penalties and charges permitted by the applicable law (e.g., 31 U.S.C. 3717 and implementing regulations).(c) If a universal service fund contributor is more than 30 days delinquent in filing a Telecommunications Reporting Worksheet Form 499-A or 499-Q, the Administrator shall assess an administrative remedial collection charge equal to the greater of $100 or an amount computed using the rate of the U.S. prime rate (in effect on the date the applicable Worksheet is due) plus 3.5 percent, of the amount due per the Administrator's calculations. In addition, the contributor is responsible for administrative charges of collection and/or penalties and charges permitted by the applicable law (e.g., 31 U.S.C. 3717 and implementing regulations). The Commission may also pursue enforcement action against delinquent contributors and late filers, and assess costs for collection activities in addition to those imposed by the Administrator.(d) In the event a contributor fails both to file the Worksheet and to pay its contribution, interest will accrue on the greater of the amounts due, beginning with the earlier of the date of the failure to file or pay.(e) If a universal service fund contributor pays the Administrator a sum that is less than the amount due for the contributor's universal service contribution, the Administrator shall adhere to the "American Rule" whereby payment is applied first to outstanding penalty and administrative cost charges, next to accrued interest, and third to outstanding principal. In applying the payment to outstanding principal, the Administrator shall apply such payment to the contributor's oldest past due amounts first. 72 FR 54219 , Sept. 24, 2007
