long-term debt of $41.4 million, payment of debt issuance costs of $11.0 million from the issuance of new debt and repurchases of common stock of $5.2 million. The cash provided by financing activities in the six months ended June 30, 2016, reflected net borrowings of revolving credit of $2.1 million offset by repayments of long-term debt of $15.0 million.
Liquidity and Capital Resources
In January 2017, Koppers Inc. completed a private placement offering of $500.0 million 6.00 percent Senior Notes due 2025 (the “2025 Notes”). The 2025 Notes will pay interest semi-annually in arrears on February 15 and August 15 beginning on August 15, 2017 and will mature on February 15, 2025 unless earlier redeemed or repurchased. The 2025 Notes are unsecured and are guaranteed by Koppers Holdings Inc. and certain of Koppers Inc.’s domestic subsidiaries.
Koppers Inc. used the proceeds from the offering of the 2025 Notes to repay its outstanding term loan and to fund a tender offer to repurchase its senior notes due 2019 (the “2019 Notes”). The tender offer for the 2019 Notes was completed in early February 2017. Any 2019 Notes remaining outstanding following the tender offer were called for redemption and Koppers Inc. concurrently satisfied and discharged its remaining obligations under the indenture governing the 2019 Notes.
In February 2017, the Company entered into a new $400.0 million senior secured revolving credit facility (the “Revolving Credit Facility”). The maturity date of the Revolving Credit Facility is February 2022. The interest rate on the Revolving Credit Facility is variable and is based on LIBOR.
Expenses associated with the redemption of the 2019 Notes, the repayment of our term loan and placement of the new Revolving Credit Facility were $13.3 million for the six months ended June 30, 2017 and are included in “Loss on Extinguishment of Debt” on the Condensed Consolidated Statement of Operations and Comprehensive Income. These costs consist of tender offer premiums, fees and write off of unamortized debt issuance costs.
Restrictions on Dividends to Koppers Holdings
Koppers Holdings depends on the dividends from the earnings of Koppers Inc. and its subsidiaries to generate the funds necessary to meet its financial obligations, including the payment of any declared dividend of Koppers Holdings. The Revolving Credit Facility prohibits Koppers Inc. from making dividend payments to Koppers Holdings unless (1) such dividend payments are permitted by the indenture governing Koppers Inc.’s 2025 Notes, (2) no event of default or potential default has occurred or is continuing under our Revolving Credit Facility, and (3) we are in pro forma compliance with our fixed charge coverage ratio covenant after giving effect to such dividend. The indenture governing the 2025 Notes restrict Koppers Inc.’s ability to finance our payment of dividends if (1) a default has occurred or would result from such financing, (2) Koppers Inc., or a restricted subsidiary of Koppers Inc. which is not a guarantor under the applicable indenture, is not able to incur additional indebtedness (as defined in the applicable indenture), and (3) the sum of all restricted payments (as defined in the applicable indenture) have exceeded the permitted amount (which we refer to as the “basket”) at such point in time.
The basket is governed by a formula based on the sum of a beginning amount, plus or minus a percentage of Koppers Inc.’s consolidated net income (as defined in the applicable indenture), plus the net proceeds of Koppers Inc.’s qualified stock issuance or conversions of debt to qualified stock, plus the net proceeds from the sale of or a reduction in an investment (as defined in the applicable indenture) or the value of the assets of an unrestricted subsidiary which is designated a restricted subsidiary. At June 30, 2017, the basket totaled $147.8 million. Notwithstanding such restrictions, the indenture governing the 2025 Notes permits an additional aggregate amount of $0.30 per share each fiscal quarter to finance dividends on the capital stock of Koppers Holdings, whether or not there is any basket availability, provided that at the time of such payment, no default in the indenture has occurred or would result from financing the dividends.
In addition, certain required coverage ratios in Koppers Inc.’s Revolving Credit Facility may restrict the ability of Koppers Inc. to pay dividends. Koppers Holdings suspended its dividend in February 2015 and does not expect to declare any dividends for the foreseeable future.
Borrowings under the Revolving Credit Facility are secured by a first priority lien on substantially all of the assets of Koppers Inc., Koppers Holdings and their material domestic subsidiaries. The Revolving Credit Facility contains certain covenants for Koppers Inc. and its restricted subsidiaries that limit capital expenditures, additional indebtedness, liens, dividends and investments or acquisitions. In addition, such covenants give rise to events of default upon the failure by Koppers Inc. and its restricted subsidiaries to meet certain financial ratios.
As of June 30, 2017, we had $187.3 million of unused revolving credit availability for working capital purposes after restrictions by various debt covenants and certain letter of credit commitments. As of June 30, 2017, $44.6 million of commitments were utilized by outstanding letters of credit.
