Senior Notes

HPIDC 2025 Notes

On March 19, 2015, our wholly-owned direct subsidiary, Helmerich & Payne International Drilling Co. (“HPIDC”), issued $500 million of 4.65 percent 10-year unsecured senior notes (the “HPIDC 2025 Notes”). Interest on the HPIDC 2025 Notes is payable semi-annually on March 15 and September 15. The debt discount is being amortized to interest expense using the effective interest method. The debt issuance costs are amortized straight-line over the stated life of the obligation, which approximates the effective interest method.

Private Exchange Offer and Consent Solicitation

On November 19, 2018, we commenced an offer to exchange (the “Exchange Offer”) any and all outstanding HPIDC 2025 Notes for (i) up to $500.0 million aggregate principal amount of new 4.65 percent 10-year unsecured senior notes of the Company (the “Company 2025 Notes”), with registration rights, and (ii) cash. Concurrently with the Exchange Offer, we solicited consents (the “Consent Solicitation”) to adopt certain proposed amendments (the “Proposed Amendments”) to the indenture governing the HPIDC 2025 Notes, which include eliminating substantially all of the restrictive covenants in such indenture and limiting the reporting covenant under such indenture. On December 20, 2018, we settled the Exchange Offer, pursuant to which we issued approximately $487.1 million in aggregate principal amount of Company 2025 Notes. Interest on the Company 2025 Notes is payable semi-annually on March 15 and September 15 of each year, commencing March 15, 2019. The terms of the Company 2025 Notes are governed by an indenture, dated December 20, 2018, as amended and supplemented by the first supplemental indenture thereto, dated December 20, 2018, each among the Company, HPIDC and Wells Fargo Bank, National Association, as trustee.

Following the consummation of the Exchange Offer, HPIDC had outstanding approximately $12.9 million in aggregate principal amount of HPIDC 2025 Notes. In connection with the Consent Solicitation, the requisite number of consents to adopt the Proposed Amendments was received. Accordingly, on December 20, 2018, HPIDC, the Company and Wells Fargo Bank, National Association, as trustee, entered into a supplemental indenture to the indenture governing the HPIDC 2025 Notes to adopt the Proposed Amendments.

Registered Exchange Offer

On February 15, 2019, we commenced a registered exchange offer (the “Registered Exchange Offer”) to exchange the Company 2025 Notes for new SEC-registered notes that are substantially identical to the terms of the Company 2025 Notes, except that the offer and issuance of the new notes have been registered under the Securities Act of 1933, as amended (the “Securities Act”), and certain transfer restrictions, registration rights and additional interest provisions relating to the Company 2025 Notes do not apply to the new notes. The Registered Exchange Offer expired on March 18, 2019, and approximately 99.99% of the Company 2025 Notes were exchanged.

The Company 2025 Notes that were not exchanged pursuant to the Registered Exchange Offer have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements or a transaction not subject to the registration requirements of the Securities Act or any state securities law.

Credit Facilities

On November 13, 2018, we entered into an unsecured revolving credit facility (the “2018 Credit Facility”), which will mature on November 13, 2023. The 2018 Credit Facility has $750 million in aggregate availability with a maximum of $75 million available for use as letters of credit. The 2018 Credit Facility also permits aggregate commitments under the facility to be increased by $300 million, subject to the satisfaction of certain conditions and the procurement of additional commitments from new or existing lenders. The 2018 Credit Facility is currently guaranteed by HPIDC, which guarantee is subject to release following or simultaneously with the repayment or exchange of the HPIDC 2025 Notes and HPIDC’s release as a guarantor under the Company 2025 Notes. The borrowings under the 2018 Credit Facility accrue interest at a spread over either the London Interbank Offered Rate (LIBOR) or the Base Rate. We also pay a commitment fee on the unused balance of the facility. Borrowing spreads as well as commitment fees are determined based on the debt rating for senior unsecured debt of the Company or, in the event the Company has no such rating, the debt rating for senior unsecured debt of HPIDC, both as determined by Moody’s and Standard & Poor’s (“S&P”). The spread over LIBOR ranges from 0.875 percent to 1.500 percent per annum and commitment fees range from 0.075 percent to 0.200 percent per annum. Based on the unsecured debt rating of HPIDC on June 30, 2019, the spread over LIBOR would have been 1.125 percent had borrowings been outstanding under the facility and commitment fees are 0.125 percent. There is a financial covenant in the 2018 Credit Facility that requires us to maintain a total debt to total capitalization ratio of less than 50 percent. The 2018 Credit Facility contains additional terms, conditions, restrictions and covenants that we believe are usual and customary in unsecured debt arrangements for companies of similar size and credit quality, including a limitation that priority debt (as defined in the credit agreement) may not exceed 17.5 percent of the net worth of the Company. As of June 30, 2019, there were no borrowings, but there was one letter of credit outstanding in the amount of $10.0 million, leaving $740.0 million available to borrow under the 2018 Credit Facility.

In connection with entering into the 2018 Credit Facility, we terminated our $300 million unsecured credit facility under the credit agreement dated as of July 13, 2016 by and among HPIDC, as borrower, the Company, as guarantor, Wells Fargo, National Association, as administrative agent, and the lenders party thereto.

At June 30, 2019, we had two outstanding letters of credit with banks under bilateral line of credit agreements, in the amounts of $25.5 million and $2.1 million, respectively.

At June 30, 2019, we also had a $12.0 million unsecured standalone line of credit facility, for the purpose of obtaining the issuance of bid and performance bonds, as needed, for international operations. Nothing was outstanding under the $12.0 million facility as of June 30, 2019.

The applicable agreements for all unsecured debt contain additional terms, conditions and restrictions that we believe are usual and customary in unsecured debt arrangements for companies that are similar in size and credit quality. At June 30, 2019, we were in compliance with all debt covenants.
