The unamortized issuance costs related to the 2017 Credit Facility were $2.9 million and $3.7 million as of June 30, 2020 and December 31, 2019, respectively, and are included in other assets in the Condensed Consolidated Balance Sheets.

On April 20, 2017, the Company issued $500 million in aggregate principal amount of 6.875% Senior Notes due 2025 (the “2017 Senior Notes”) in a private placement offering. Interest on the 2017 Senior Notes is payable in arrears semi-annually in May and November of each year, beginning in November 2017.

Prior to May 1, 2020, the Company could have redeemed the 2017 Senior Notes at a redemption price equal to 100% of their principal amount plus a “make-whole” premium described in the indenture. In addition, prior to May 1, 2020, the Company also could have redeemed up to 40% of the original aggregate principal amount of the notes at a redemption price of 106.875% of their principal amount with the proceeds received by the Company from any offering of the Company’s equity. Since May 1, 2020, the Company may redeem the 2017 Senior Notes at specified redemption prices described in the indenture. Upon a change of control, holders of the 2017 Senior Notes may require the Company to repurchase all or part of the 2017 Senior Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.

The 2017 Senior Notes are senior unsecured obligations of the Company and are guaranteed by substantially all of the Company’s existing and future subsidiaries that also guarantee obligations under the Company’s 2017 Credit Facility, as defined below. In addition, the indenture for the 2017 Senior Notes provides for customary covenants, including events of default and restrictions on the payment of dividends and share repurchases.

On April 20, 2017, the Company entered into a credit agreement (the “2017 Credit Facility”) with SunTrust Bank, now known as Truist Bank, as Administrative Agent, Swing Line Lender and L/C Issuer and a syndicate of other lenders. The 2017 Credit Facility provides for a $350 million revolving credit facility (the “2017 Revolver”) and a sublimit for the issuance of letters of credit and swingline loans up to the aggregate amount of $150 million and $10 million, respectively, both maturing on April 20, 2022 unless any of the Convertible Notes, as defined below, are outstanding on December 17, 2020, in which case all such borrowings will mature on

December 17, 2020 (the “spring-forward provision”), provided however (i) if the Convertible Notes are refinanced in full with the proceeds of permitted refinancing indebtedness in accordance with the terms of the 2017 Credit Facility, the maturity date for the 2017 Credit Facility will remain April 20, 2022 and (ii) if the Company issues “New Convertible Notes” (as defined in the 2017 Credit Facility) and retires the Convertible Notes in full, the maturity date for the 2017 Credit Facility will be the earlier of (x) April 20, 2022 or (y) 90 days prior to the maturity date for such New Convertible Notes. The 2017 Credit Facility also permits additional borrowings in an aggregate amount of $150 million, which can be in the form of increased capacity on the 2017 Revolver or the establishment of one or more term loans.

Borrowings under the 2017 Revolver bear interest, at the Company’s option, at a rate equal to (a) LIBOR plus a margin of between 1.50% and 3.00% or (b) a base rate (determined by reference to the highest of (i) the administrative agent’s prime lending rate, (ii) the federal funds effective rate plus 50 basis points, (iii) the LIBOR rate for a one-month interest period plus 100 basis points and (iv) 0%), plus a margin of between 0.50% and 2.00%, in each case based on the Consolidated Leverage Ratio (as defined in the 2017 Credit Facility). In addition to paying interest on outstanding principal under the 2017 Credit Facility, the Company will pay a commitment fee to the lenders under the 2017 Revolver in respect of the unutilized commitments thereunder. The Company will pay customary letter of credit fees. If an event of default occurs and is continuing, the otherwise applicable margin and letter of credit fees will be increased 2% per annum. The weighted-average annual interest rate on borrowings under the 2017 Revolver was approximately 3.66% during the six months ended June 30, 2020.

The 2017 Credit Facility contains customary covenants for credit facilities of this type, including maximum consolidated leverage ratios ranging from 4.00:1.00 to 3.25:1.00 over the life of the facility and a minimum consolidated fixed charge coverage ratio of 1.25:1.00. On May 7, 2019, certain provisions of the 2017 Credit Facility were amended, including setting the maximum leverage ratio at 3.50:1.00 for the remainder of its term, thus eliminating the step down from 3.50:1:00 to 3.25:1.00. Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the 2017 Credit Facility; additionally, the obligations are secured by a lien on all personal property of the Company and its subsidiaries guaranteeing these obligations.

As of June 30, 2020, there was $250 million available under the 2017 Revolver, and the Company had not utilized the 2017 Credit Facility for letters of credit. The Company was in compliance with the financial covenants under the 2017 Credit Facility as of June 30, 2020.

As a result of the spring-forward provision mentioned above, the facility will mature on December 17, 2020 if the Convertible Notes remain outstanding at that time. The Company does not have call rights that allow it to unilaterally redeem the Convertible Notes. Due to the spring-forward provision in the 2017 Credit Facility, all borrowings under the facility are included in “Current maturities of long-term debt” on the Condensed Consolidated Balance Sheet as of June 30, 2020. The Company continues to evaluate options to address the spring-forward provision and refinancing or retirement of the outstanding Convertible Notes.

Convertible Notes

On June 15, 2016, the Company issued $200 million of 2.875% Convertible Senior Notes due June 15, 2021 (the “Convertible Notes”) in a private placement offering. The Convertible Notes are unsecured obligations of the Company and do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company. The Convertible Notes bear interest at a rate of 2.875% per year, payable in cash semi-annually in June and December, and are included in “Current maturities of long-term debt” on the Condensed Consolidated Balance Sheet as of June 30, 2020.

Prior to January 15, 2021, the Convertible Notes will be convertible only under the following circumstances: (1) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (2) if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion rate of 33.0579 (or $39.32) on each applicable trading day; or (3) upon the occurrence of specified corporate events. On or after January 15, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.

The Convertible Notes will be convertible at an initial conversion rate of 33.0579 shares of the Company’s common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $30.25. The conversion rate will be subject to adjustment for some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company is required to increase, in certain circumstances, the

conversion rate for a holder who elects to convert their Convertible Notes in connection with such a corporate event including customary conversion rate adjustments in connection with a “make-whole fundamental change” described in the indenture. Upon conversion, and at the Company’s election, the Company may satisfy its conversion obligation with cash, shares of its common stock or a combination thereof. As of June 30, 2020, the conversion provisions of the Convertible Notes have not been triggered.
