During the six months ended June 30, 2019, the Company executed several debt transactions which are described in more detail below. These transactions include: (i) open market purchases of our 5.625% senior secured notes due 2024 (“2024 notes”), (ii) extension of the maturity of our $900.0 million revolving credit facility (“2023 facility”) and (iii) privately negotiated purchases of our 2024 notes and a partial repayment of our senior secured term loan facility due 2024 (“2024 term loan”) with the proceeds from the issuance of 6.75% senior secured notes due 2027 (“2027 notes”). These transactions collectively have extended our debt maturity profile and reduced the amount of long-term debt outstanding.

In the first quarter of 2019, the Company executed a series of open market purchases of its 2024 notes. These transactions resulted in $20.4 million in aggregate principal amount of the 2024 notes being repurchased at prices ranging from 94.9% to 95.9% of par value.

These repurchases of the 2024 notes were considered to be debt extinguishments. As such, we recognized a gain on debt extinguishment of $0.7 million which was recorded as a component of interest expense in the first quarter of 2019. Of this gain, approximately $0.9 million was attributable to the repurchase of the notes at a discount to par value which was partially offset by a $0.2 million write-off of unamortized debt issuance costs associated with the 2024 notes repurchased.

In April 2019, the Company extended the maturity date of its 2023 facility by 20 months to November 22, 2023. All other material terms of the 2023 facility remain unchanged from those of the previous agreement.

In connection with the 2023 facility amendment we incurred $1.2 million in lender and third-party fees which, together with $5.9 million in remaining unamortized debt issuance costs, have been recorded as other assets and are being amortized over the remaining contractual life of the 2023 facility on a straight-line basis.

In May 2019, we completed a private offering of $400.0 million in aggregate principal amount of 2027 notes at an issue price equal to 100% of their par value. The proceeds from the issuance of the 2027 notes were used, together with cash on hand, to purchase $97.0 million in aggregate principal amount of 2024 notes, to repay $300.0 million of the 2024 term loan and to pay related transaction fees and expenses.

In connection with the issuance of the 2027 notes, we incurred $6.1 million of various third-party fees and expenses. Of these costs, $2.1 million were recorded to interest expense in the second quarter of 2019. The remaining $4.0 million in costs incurred have been recorded as a reduction to long-term debt and are being amortized over the contractual life of the 2027 notes using the effective interest method. Further, we recorded an additional $2.2 million to interest expense in the second quarter of 2019 related to the write-off of unamortized debt discount and debt issuance costs in connection with the partial repayment of the 2024 term loan.

As of June 30, 2019, we have $400.0 million outstanding in aggregate principal amount of the 2027 notes which mature on June 1, 2027. Interest accrues on the 2027 notes at a rate of 6.75% per annum and is payable semi-annually on June 1 and December 1 of each year, commencing on December 1, 2019.

The terms of the 2027 notes are governed by the indenture, dated as of the May 30, 2019 (the “Indenture”), among the Company, the guarantors named therein and Wilmington Trust, National Association, as trustee and as notes collateral agent. The 2027 notes, subject to certain exceptions, are guaranteed, jointly and severally, on a senior secured basis, by certain of the Company’s direct and indirect wholly owned subsidiaries (the “Guarantors”). All obligations under the 2027 notes, and the guarantees of those obligations, are secured by substantially all of the assets of the Company and the Guarantors subject to certain exceptions and permitted liens, including a first-priority security interest in such assets that constitute Notes Collateral (as defined below) and a second-priority security interest in such assets that constitute ABL Collateral (as defined below).

“ABL Collateral” includes substantially all presently owned and after-acquired accounts, inventory, rights of an unpaid vendor with respect to inventory, deposit accounts, investment property, cash and cash equivalents, and instruments and chattel paper and general intangibles, books and records and documents related to and proceeds of each of the foregoing. “Notes Collateral” includes all collateral which is not ABL Collateral.

The Indenture contains restrictive covenants that limit the ability of the Company and its restricted subsidiaries to, among other things, incur additional debt or issue preferred stock, create liens, create restrictions on the Company’s subsidiaries’ ability to make payments to the Company, pay dividends and make other distributions in respect of the Company’s and its subsidiaries’ capital stock, make certain investments or certain other restricted payments, guarantee indebtedness, designate unrestricted subsidiaries, sell certain kinds of assets, enter into certain types of transactions with affiliates, and effect mergers and consolidations.

At any time prior to June 1, 2022, the Company may redeem the 2027 notes in whole or in part at a redemption price equal to 100% of the principal amount of the 2027 notes plus the “applicable premium” set forth in the Indenture. At any time on or after June 1, 2022, the Company may redeem the 2027 notes at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to the redemption date. At any time and from time to time during the 36-month period following the Closing Date, the Company may redeem up to 10% of the aggregate principal amount of the 2027 notes during each twelve-month period commencing on the Closing Date at a redemption price of 103% of the aggregate principal amount thereof plus accrued and unpaid interest to the redemption date. In addition, at any time prior to June 1, 2022, the Company may redeem up to 40% of the aggregate principal amount of the 2027 notes with the net cash proceeds of one or more equity offerings, as described in the Indenture, at a price equal to 106.750% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date. If the Company experiences certain change of control events, holders of the 2027 notes may require it to repurchase all or part of their 2027 notes at 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the repurchase date.

As of June 30, 2019 and December 31, 2018, the Company does not have any financial instruments which are measured at fair value on a recurring basis. We have elected to report the value of our 2027 notes, 2024 notes, 2024 term loan and 2023 facility at amortized cost. The fair values of the 2027 notes, 2024 notes and the 2024 term loan at June 30, 2019 were approximately $423.4 million, $597.2 million and $156.8 million, respectively, and were determined using Level 2 inputs based on market prices. The carrying value of the 2023 facility at June 30, 2019 approximates fair value as the rates are comparable to those at which we could currently borrow under similar terms, are variable and incorporate a measure of our credit risk. As such, the fair value of the 2023 facility was also classified as Level 2 in the hierarchy.

We were not in violation of any covenants or restrictions imposed by any of our debt agreements at June 30, 2019.
