You must furnish us and the bank with authorizations as necessary to permit us to make withdrawals from the Account by electronic funds transfer. Each week, we will transfer from the Account an amount equal to the royalty fees and NMF contribution due from you based on Gross Sales for the preceding week, as well as any other fees due to us or our affiliates. You agree to maintain sufficient funds in the Account at all times to cover all royalty fees, Brand Marketing Fund contributions and other fees payable to us or our affiliates. If funds in the Account are insufficient to cover the amounts payable at the time we make our weekly electronic funds transfer, the amount of the shortfall will be deemed overdue.
• 5.5. Interest and Late Fees. If any sums required to be paid by you to us under this Agreement are not received in full by us when due, we will assess a late fee of one hundred dollars ($100) for each week that any payment is delinquent.
