Convertible Senior Notes |
Convertible Senior Notes | Note 9. Convertible Senior Notes In May 2020, the Company issued $115.0 million aggregate principal amount of 3.00% convertible senior notes due in 2025 (the “Senior Notes”), which includes the initial purchasers’ exercise in full of their option to purchase an additional $15.0 million principal amount of the Senior Notes, in a private placement exempt from registration under the Securities Act of 1933. The Senior Notes are governed by an indenture (the “Indenture”) dated May 26, 2020 between the Company, as issuer, and U.S. Bank National Association, as trustee (the “Trustee”). The Company received $111.3 million from the offering, net of underwriting discounts and commissions of $3.7 million, and incurred approximately $0.3 million in third-party offering related costs. The Senior Notes bear cash interest at a rate of 3.00%, payable semi-annually on June 1 and December 1 of each year, beginning on December 1, 2020 and will mature on June 1, 2025, unless earlier repurchased, redeemed, or converted in accordance with the terms of the Senior Notes. At September 30, 2021, accrued interest of $1.2 million is included in accounts payable and accrued liabilities in the accompanying consolidated financial statements. The Senior Notes comprise the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Senior Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries. At any time before the close of business on the scheduled trading day immediately before the maturity date, holders of the Senior Notes may convert their Senior Notes at their option into shares of the Company’s common stock. The Senior Notes are initially convertible into approximately 4,810,002 shares of the Company’s common stock based on the initial conversion rate of 41.8261 shares of the Company’s common stock per $1,000 principal amount of the Senior Notes, which represents an initial conversion price of approximately $23.91 per share of the Company’s common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. Also, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time and is determined by reference to a make-whole table set forth in the Indenture governing the Senior Notes. However, in no event will the conversion rate be increased to an amount that exceeds 48.10 shares of the Company’s common stock per $1,000 principal amount of Senior Notes. In addition, the holders of the Senior Notes may require the Company to repurchase the Senior Notes at par value plus accrued and unpaid interest following the occurrence of a “Fundamental Change” (as described in the Indenture). On or after June 5, 2023, the Company may redeem the Senior Notes at its option, in whole and not in part, at a cash redemption price equal to the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, if:
| (1) | The last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company send the related redemption notice; and (ii) the trading day immediately before the date the Company sends such notice; and
| (2) | A registration statement covering the resale of the shares of the Company’s common stock issuable upon conversion of the Senior Notes is effective and available for use and is expected to remain effective and available during the redemption period as of the date the redemption notice is sent.
The Senior Notes contain customary terms and events of default. If an event of default arising out of certain events of bankruptcy, insolvency, or reorganization involving the Company or a significant subsidiary (as set forth in the Indenture) occurs with respect to the Company, the principal amount of the Senior Notes and accrued and unpaid interest, if any, will automatically become immediately due and payable. If any other event of default (as defined in the Indenture) occurs and is continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding Senior Notes may declare the principal amount of the Senior Notes to be due and payable immediately by notice to the Company. There were no events of default at September 30, 2021. The Senior Notes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options (“ASC 470-20”) and ASC 815-40, Contracts in Entity’s Own Equity (“ASC 815-40”). Under ASC 815-40, to qualify for equity classification (or nonbifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s stock and (2) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the Senior Notes do contain embedded features indexed to its own stock, but do not meet the requirements for bifurcation, and therefore do not need to be separately accounted for as an equity component. Since the embedded conversion feature meets the equity scope exception from derivative accounting, and also since the embedded conversion option does not need to be separately accounted for as an equity component under ASC 470-20, the proceeds received from the issuance of the convertible debt was recorded as a liability on the consolidated balance sheet. The Company incurred approximately $4.1 million of debt issuance costs relating to the issuance of the Senior Notes, which were recorded as a reduction to the Senior Notes on the consolidated balance sheet. The debt issuance costs are being amortized and recognized as additional interest expense over the expected life of the Senior Notes using the effective interest rate method. We determined the expected life of the debt is equal to the five-year term of the Senior Notes. The effective interest rate on the Senior Notes is 3.74%. Senior Notes payable consisted of the following at September 30, 2021 (in thousands): ​

​ The Company’s Senior Notes payable of $115.0 are due and payable in 2025. In connection with the issuance of the Senior Notes, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) to use its best efforts to file a registration statement for the resale of the Senior Notes and the shares of the Company’s common stock issuable upon conversion of the Senior Notes, to cause the registration statement to become effective by January 31, 2021, and to keep the registration statement continuously effective for a specified period of time. If the Company fails to satisfy certain of its obligations under the Registration Rights Agreement (a “Registration Default”), it will be required to pay additional interest on the Senior Notes. Such additional interest will accrue at a rate per annum equal to 0.25% of the principal amount thereof for the first 90 days beginning on, and including the date on which such Registration Default occurs and, thereafter, at a rate per annum equal to 0.50% of the principal amount thereof. However, in no event will such additional interest, together with any special interest that accrues pursuant to the Indenture accrue on any day on a Note at a combined rate per annum that exceeds 0.50%. Additionally, if a Registration Default exists on the maturity date for the Senior Notes, then, in addition to any additional interest otherwise payable, the Company will be required to make a cash payment to each noteholder in an amount equal to 3% of the principal amount of Senior Notes outstanding and held by such holder as of the close of business on the business day immediately before the maturity date. As of September 30, 2021, the Company has not accrued any fees or expenses associated with the Registration Rights Agreement as no Registration Default exists and, therefore, it is not probable that a payment would be required. In December 2020, the Company filed an automatic shelf registration statement to register the resale of the Senior Notes and the shares of the Company’s common stock issuable upon conversion of the Senior Notes.
