8. DEBT

​

Outstanding debt, net of debt issuance costs, consisted of the following (dollars in millions):

​

Huntsman Corporation

​

​

Huntsman International

​

​

Direct and Subsidiary Debt

​

Huntsman Corporation’s direct debt and guarantee obligations consist of a guarantee of certain indebtedness incurred from time to time to finance certain insurance premiums. Substantially all of our other debt, including the facilities described below, has been incurred by our subsidiaries (primarily Huntsman International). Huntsman Corporation is not a guarantor of such subsidiary debt.

​

Certain of our subsidiaries have third-party debt agreements that contain certain restrictions with regard to dividends, distributions, loans or advances. In certain circumstances, the consent of a third party would be required prior to the transfer of any cash or assets from these subsidiaries to us.

​

Debt Issuance Costs

​

We record debt issuance costs related to a debt liability on the balance sheet as a reduction to the face amount of that debt liability. As of June 30, 2019 and December 31, 2018, the amount of debt issuance costs directly reducing the debt liability was $12 million and $8 million, respectively. We record the amortization of debt issuance costs as interest expense.

​

Revolving Credit Facility

​

On May 21, 2018, Huntsman International entered into a new $1.2 billion senior unsecured revolving credit facility (the “2018 Revolving Credit Facility”). Borrowings under the 2018 Revolving Credit Facility will bear interest at the rates specified in the credit agreement governing the 2018 Revolving Credit Facility, which will vary based on the type of loan and Huntsman International’s debt ratings. Unless earlier terminated, the 2018 Revolving Credit Facility will mature in May 2023. Huntsman International may increase the 2018 Revolving Credit Facility commitments up to an additional $500 million, subject to the satisfaction of certain conditions.

​

In connection with entering into the 2018 Revolving Credit Facility, Huntsman International terminated all commitments and repaid all obligations under the Prior Credit Facility. In addition, we recognized a loss on early extinguishment of debt of $3 million. Upon the termination of the Prior Credit Facility, all guarantees of the obligations under the Prior Credit Facility were terminated, and all liens granted under the Prior Credit Facility were released. As of June 30, 2019, our 2018 Revolving Credit Facility was as follows (dollars in millions):

​

​

​

A/R Programs

​

Our U.S. A/R Program and our European accounts receivable securitization program (“EU A/R Program” and collectively with the U.S. A/R Program, “A/R Programs”) are structured so that we transfer certain of our trade receivables to the U.S. special purpose entity (“U.S. SPE”) and the European special purpose entity (“EU SPE”) in transactions intended to be true sales or true contributions. The receivables collateralize debt incurred by the U.S. SPE and the EU SPE. Information regarding our A/R Programs as of June 30, 2019 was as follows (monetary amounts in millions):

​

On April 18, 2019, we entered into amendments to the EU A/R Program (the “European Amendment”) and the U.S. A/R Program (the “U.S. Amendment”). The European Amendment, among other things, extended the scheduled commitment termination date of the loan facility to April 2022, reduced the facility maximum funding availability from €150 million to €100 million and made certain other amendments. The U.S. Amendment, among other things, extended the scheduled commitment termination date of the loan facility to April 2022 and made certain other amendments.

​

​

​

​

​

As of June 30, 2019 and December 31, 2018, $372 million and $341 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs.

​

Notes

​

On March 13, 2019, Huntsman International completed a $750 million offering of its 4.50% senior notes due 2029 (“2029 Senior Notes”). On March 27, 2019, Huntsman International applied the net proceeds of the offering of the 2029 Senior Notes to redeem in full $650 million in aggregate principal amount of its 4.875% senior notes due 2020 (“2020 Senior Notes”) and also paid associated costs and accrued interest of $21 million and $12 million, respectively. In addition, we recognized a loss on early extinguishment of debt of $23 million.

The 2029 Senior Notes bear interest at 4.50% per year, payable semi-annually on May 1 and November 1, and will mature on May 1, 2029. Huntsman International may redeem the 2029 Senior Notes in whole or in part at any time prior to February 1, 2029 at a price equal to 100% of the principal amount thereof plus a “make-whole” premium and accrued and unpaid interest. Huntsman International may redeem the 2029 Senior Notes at any time, in whole or from time to time in part, on or after February 1, 2029 at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest.

Note Payable from Huntsman International to Huntsman Corporation

​

As of June 30, 2019, we had a loan of $473 million to our subsidiary, Huntsman International (the “Intercompany Note”). The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of June 30, 2019 on our condensed consolidated balance sheets. As of June 30, 2019, under the terms of the Intercompany Note, Huntsman International promises to pay us interest on the unpaid principal amount at a rate per annum based on the previous monthly average borrowing rate obtained under our U.S. A/R Program, less 10 basis points (provided that the rate shall not exceed an amount that is 25 basis points less than the monthly average borrowing rate obtained for the U.S. LIBOR-based borrowings under our 2018 Revolving Credit Facility).

​

Compliance with Covenants

​

Our 2018 Revolving Credit Facility contains a financial covenant regarding the leverage ratio of Huntsman International and its subsidiaries. The 2018 Revolving Credit Facility also contains other customary covenants and events of default for credit facilities of this type. Upon an event of default that is not cured or waived within any applicable cure periods, in addition to other remedies that may be available to the lenders, the obligations under the 2018 Revolving Credit Facility may be accelerated.

​

The agreements governing our A/R Programs also contain certain receivable performance metrics. Any material failure to meet the applicable A/R Programs’ metrics could lead to an early termination event under the A/R Programs, which could require us to cease our use of such facilities, prohibiting us from additional borrowings against our receivables or, at the discretion of the lenders, requiring that we repay the A/R Programs in full. An early termination event under the A/R Programs would also constitute an event of default under our 2018 Revolving Credit Facility, which could require us to pay off the balance of the 2018 Revolving Credit Facility in full and could result in the loss of our 2018 Revolving Credit Facility.

​

We believe that we are in compliance with the covenants contained in the agreements governing our material debt instruments, including our 2018 Revolving Credit Facility, our A/R Programs and our notes.
