Late Payment Charge. If any portion of the payment is received by Qwest after the Payment Due Date, or if any portion of the payment is received by Qwest in funds that are not immediately available, then a late payment charge will be due to Qwest. The late payment charge is the portion of the payment not received by the Payment Due Date multiplied by a late factor. The late factor is the lesser of (i) the highest interest rate (in decimal value) which may be levied by law for commercial transactions, compounded daily for the number of Days from the Payment Due Date to and including the date that the CLEC actually makes the payment to Qwest; or (ii) 0.000407 per Day, compounded daily for the number of Days from the Payment Due Date to and including the date that the CLEC actually makes the payment to Qwest.
