Note 9.    Debt, Credit Facility and Leases

Senior Notes

On February 19, 2020, we completed an offering of $475 million in aggregate principal amount of our 7.25% Senior Notes due February 15, 2028 ("Senior Notes") under our shelf registration statement previously filed with the SEC. The Senior Notes are governed by the Indenture, dated as of February 19, 2020, among Hecla Mining Company ("Hecla") and certain of our subsidiaries and The Bank of New York Mellon Trust Company, N.A., as trustee. On March 19, 2020, the net proceeds from the offering of the Senior Notes ($469.5 million) were used, together with cash on hand, to redeem all of our previously-outstanding 6.875% Senior Notes that were due in 2021 and had a principal balance of $506.5 million ("2021 Notes").

The Senior Notes are recorded net of a 1.16% initial purchaser discount totaling $5.5 million at the time of the February 2020 issuance. The discount and issuance costs had an unamortized balance of $6.0 million as of March 31, 2020.  The Senior Notes bear interest at a rate of 7.25% per year from the date of issuance or from the most recent payment date on which interest has been paid or provided for.  Interest on the Senior Notes is payable on February 15 and August 15 of each year, commencing August 15, 2020. During each of the three month periods ended March 31, 2020 and 2019, interest expense on the statement of operations and comprehensive loss related to the Senior Notes and 2021 Notes and amortization of the initial purchaser discount and fees related to the issuance of the Senior Notes and 2021 Notes totaled $13.7 million and $9.1 million, respectively. Interest expense for the three month period ended March 31, 2020 included amounts recorded for (i) interest recognized on both the Senior Notes and 2021 Notes for an overlapping period of approximately one month, as the Senior Notes were issued on February 19, 2020 and the 2021 Notes were redeemed on March 19, 2020, and (ii) $1.7 million in unamortized initial purchaser discount on the 2021 Notes upon redemption. As of March 31, 2020, the long-term debt balance on the Senior Notes was $469.0 million, consisting of the principal amount of $475.0 million less $6.0 million in amortized discount and issuance costs. As of December 31, 2019, the long-term debt balance on the 2021 Notes was $504.7 million, consisting of the total principal amount of $506.5 million less $1.8 million in amortized discount.

The Senior Notes are guaranteed on a senior unsecured basis by certain of our subsidiaries (the "Guarantors"). The Senior Notes and the guarantees are, respectively, Hecla's and the Guarantors' general senior unsecured obligations and are subordinated to all of Hecla's and the Guarantors' existing and future secured debt to the extent of the assets securing that secured debt.  In addition, the Senior Notes are effectively subordinated to all of the liabilities of Hecla's subsidiaries that are not guaranteeing the Senior Notes, to the extent of the assets of those subsidiaries.

The Senior Notes will be redeemable in whole or in part, at any time and from time to time on or after February 15, 2023, on the redemption dates and at the redemption prices specified in the Indenture, plus accrued and unpaid interest, if any, to the date of redemption.  Prior to February 15, 2023, we may redeem some or all of the Senior Notes at a redemption price of 100% of the principal amount, plus accrued interest, if any, to the redemption date, plus a "make whole" premium. We may redeem up to 35% of the Senior Notes before February 15, 2023 with the net cash proceeds of certain equity offerings.

Upon the occurrence of a change of control (as defined in the Indenture), each holder of Senior Notes will have the right to require us to purchase all or a portion of such holder's Senior Notes pursuant to a change of control offer (as defined in the Indenture), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of holders of the Senior Notes on the relevant record date to receive interest due on the relevant interest payment date.

Ressources Québec Notes

On March 5, 2018, we entered into a note purchase agreement pursuant to which we issued CAD$40 million (approximately USD$30.8 million at the time of the transaction) in aggregate principal amount of our Series 2018-A Senior Notes due May 1, 2021 (the “RQ Notes”) to Ressources Québec, a subsidiary of Investissment Québec, a financing arm of the Québec government. Because the RQ notes were denominated in CAD, the reported USD-equivalent principal balance changed with movements in the exchange rate. The RQ Notes were issued at a discount of 0.58%, or CAD$0.2 million, and bore interest at a rate of 4.68% per year, payable on May 1 and November 1 of each year, commencing May 1, 2018. The RQ Notes were senior and unsecured and were pari passu in all material respects with the 2021 Notes, including with respect to guarantees of the RQ Notes by certain of our subsidiaries. The net proceeds from the RQ Notes were required to be used for development and expansion of our Casa Berardi mine. In December 2019, we prepaid the obligation related to the RQ Notes through issuance of approximately 10.7 million shares of our common stock having a total value of approximately CAD$43.8 million (approximately USD$33.5 million). During the three months ended March 31, 2019, interest expense related to the RQ Notes, including discount and origination fees, totaled $0.4 million.

Credit Facility

In July 2018, we entered into a $250 million senior secured revolving credit facility which replaced our previous $100 million credit facility. The facility has a term ending on February 7, 2023. The credit facility is collateralized by the assets of or shares of common stock held in our material subsidiaries, including those owning the Casa Berardi mine and our Nevada operations, and by our joint venture interests holding 100% ownership of the Greens Creek mine, all of our rights and interests in the joint venture agreement, and all of our rights and interests in the assets of the joint venture. Below is information on the interest rates, standby fee, and financial covenant terms under our current credit facility as of March 31, 2020:

Interest rates:
Spread over the London Interbank Offered Rate	2.25	-	4.00%
Spread over alternative base rate	1.25	-	3.00%
Standby fee per annum on undrawn amounts	0.5625	-	1.00%
Covenant financial ratios:

⁽¹⁾ The leverage ratio will change to 4.00:1 effective July 1, 2020.

We are also able to obtain letters of credit under the facility, and for any such letters we are required to pay a participation fee of between 2.25% and 4.00% of the amount of the letters of credit based on our total leverage ratio, as well as a fronting fee to each issuing bank of 0.20% annually on the average daily dollar amount of any outstanding letters of credit.  There were $28.7 million in letters of credit outstanding as of March 31, 2020.

We believe we were in compliance with all covenants under the credit agreement as of March 31, 2020.  We drew $210.0 million on the facility during the first quarter of 2020, and that amount was outstanding as of March 31, 2020 and the date of this report.

Finance Leases

We have entered into various lease agreements, primarily for equipment at our Greens Creek, Lucky Friday, Casa Berardi and Nevada Operations units, which we have determined to be finance leases.  At March 31, 2020, the total liability balance associated with finance leases, including certain purchase option amounts, was $11.2 million, with $5.4 million of the liability classified as current and the remaining $5.8 million classified as non-current. At December 31, 2019, the total liability balance associated with finance leases was $12.6 million, with $5.4 million of the liability classified as current and the remaining $7.2 million classified as non-current.

Operating Leases

We have entered into various lease agreements, primarily for equipment, buildings and other facilities, and land at our operating units and corporate offices, which we have determined to be operating leases.  Some of the operating leases allow for extension of the lease beyond the current term at our option. We have considered the likelihood and estimated duration of the extension options in determining the lease term for measurement of the liability and right-of-use asset. For our operating leases as of March 31, 2020, we have assumed discount rates of between 5% and 6.5%, and the weighted average discount rate was 6.5%. At March 31, 2020, the total liability balance associated with the operating leases was $14.9 million, with $4.8 million of the liability classified as current and the remaining $10.1 million classified as non-current. At December 31, 2019, the total liability balance associated with the operating leases was $16.4 million, with $5.6 million of the liability classified as current and the remaining $10.8 million classified as non-current.
