At September 30, 2018, the current portion of long-term debt consisted of $698.0 million of bank revolving loans under our amended and restated senior secured credit facility and $35.4 million of other foreign bank revolving and term loans and other obligations.

On April 16, 2018, we redeemed all remaining outstanding 5% Senior Notes due 2020, or the 5% Notes, ($280.0 million aggregate principal amount) at a redemption price of 100 percent of their principal amount plus accrued and unpaid interest up to the redemption date. We funded this redemption with revolving loan borrowings under our amended and restated senior secured credit facility and cash on hand.

On May 30, 2018, we and certain of our wholly owned subsidiaries entered into a First Amendment to Amended and Restated Credit Agreement, or the First Amendment, with the Lenders (as defined therein) and Wells Fargo National Association, as Administrative Agent. The First Amendment amended our amended and restated senior secured credit facility dated as of March 24, 2017, or the Credit Agreement.

Pursuant to the First Amendment, the date until which revolving loans under the Credit Agreement generally may be borrowed, repaid and reborrowed from time to time was extended from March 24, 2022 to May 30, 2023. The First Amendment also extended the maturity date of the term loans under the Credit Agreement from March 24, 2023 to May 30, 2024 and provides that the term loans under the Credit Agreement are payable in installments as follows (expressed as a percentage of the original principal amount of the applicable term loan outstanding on the date that it is borrowed), with the remaining outstanding principal amounts to be repaid on the maturity date of the term loans:



Date	Percentage
December 31, 2019	5.0	%
December 31, 2020	10.0	%
December 31, 2021	10.0	%
December 31, 2022	10.0	%
December 31, 2023	10.0	%

In addition, pursuant to the First Amendment, during the period from May 30, 2018 through June 30, 2018, the applicable margin for term loans and the revolving loans under the Credit Agreement was (i) with respect to base rate and Canadian prime rate loans, 0.50 percent and (ii) with respect to Eurodollar Rate, Euro Rate and CDOR Rate loans, 1.50 percent. The applicable margin for term loans and revolving loans under the Credit Agreement will be reset quarterly based on our Total Net Leverage Ratio as provided in the Credit Agreement, beginning no sooner than July 1, 2018 (with respect to the quarterly period ended March 31, 2018). Pursuant to the First Amendment, the maximum applicable margin was decreased from 1.00 percent to 0.50 percent with respect to base rate and Canadian prime rate loans and from 2.00 percent to 1.50 percent with respect to Eurodollar Rate, Euro Rate and CDOR Rate loans.

The applicable commitment fee payable by revolving borrowers on the daily average unused portion of the commitment in respect of revolving loans under the Credit Agreement was 0.30 percent per annum for the period from May 30, 2018 through June 30, 2018. Pursuant to the First Amendment, the maximum applicable commitment fee was decreased from 0.35 percent to 0.30 percent and will be reset quarterly based upon our Total Net Leverage Ratio as provided in the Credit Agreement, beginning no sooner than July 1, 2018 (with respect to the quarterly period ended March 31, 2018).

Additionally, the First Amendment includes other changes to the Credit Agreement, including certain changes which provide us with additional flexibility to pursue our strategic initiatives.

As a result of the redemption of the remaining outstanding 5% Notes and the First Amendment, we recorded a pre-tax charge for the loss on early extinguishment of debt of $2.5 million during the second quarter of 2018.
