Convertible Senior Notes | 6. Convertible Senior Notes In December 2018, the Company issued $240,000 aggregate principal amount of 1.25% convertible senior notes (“Notes”) due December 15, 2023, unless earlier repurchased by the Company or converted by the holder pursuant to their terms. Interest is payable semiannually in arrears on June 15 and December 15 of each year, commencing on June 15, 2019. The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes are unsecured and rank: senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to the Company’s unsecured indebtedness that is not subordinated; effectively junior in right of payment to any of the Company’s senior, secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities incurred by the Company’s subsidiaries. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. The Notes have an initial conversion rate of 18.8076 shares of common stock per $1 principal amount of Notes. This represents an initial effective conversion price of approximately $53.17 per share of common stock and 4,513,824 shares issuable upon conversion. Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the Notes will not receive any cash payment representing accrued and unpaid interest, if any, upon conversion of a Note, except in limited circumstances. Accrued but unpaid interest will be deemed to be paid by cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock paid or delivered, as the case may be, to the holder upon conversion of Notes. Prior to the close of business on September 14, 2023, the Notes will be convertible at the option of holders during certain periods, only upon satisfaction of certain conditions set forth below. On or after September 15, 2023, 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 at the conversion price at any time regardless of whether the conditions set forth below have been met. Holders may convert all or a portion of their Notes prior to the close of business on September 14, 2023, in multiples of $1 principal amount, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on March 31, 2019 (and only during such calendar quarter), if the last reported sales 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, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period, or the Notes measurement period, in which the “trading price” (as defined in the Indenture) per $1 principal amount of notes for each trading day of the Notes measurement period 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; • if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on September 14, 2023; or • upon the occurrence of specified corporate events. As of June 30, 2020, the Notes were not convertible. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and with similar maturity, the Company estimated the implied market interest rate of its Notes to be approximately 7.30%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component of the Notes, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the Notes, which resulted in a fair value of the liability component of $181,500 upon issuance, calculated as the present value of future contractual payments based on the $240,000 aggregate principal amount. The excess of the principal amount of the liability component over its carrying amount, or the debt discount, is amortized to interest expense over the term of the Notes. The $58,500 difference between the In accounting for the transaction costs related to the issuance of the Notes, the Company allocated the total amount incurred to the liability and equity components in proportion to the allocation of proceeds. Transaction costs attributable to the liability component, totaling $ 4,808 , are being amortized to expense over the term of the Notes, and transaction costs attributable to the equity component, totaling $ 1,550 , and were included with the equity component in shareholders’ equity. The Notes consist of the following as of: As of June 30, 2020 December 31, 2019 Liability component: Principal $ 240,000 $ 240,000 Less: Debt discount, net of amortization (46,157 ) (52,051 ) Net carrying amount $ 193,843 $ 187,949 Equity component (a) 56,950 56,950 (a) Recorded in the consolidated balance sheet within additional paid-in capital, net of $1,550 transaction costs in equity. The following table sets forth total interest expense recognized related to the Notes: Three Months Ended June 30, 2020 2019 1.25% coupon $ 750 $ 742 Amortization of debt discount and transaction costs 2,970 2,792 $ 3,720 $ 3,534 As of June 30, 2020, the fair value of the Notes, which was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, quoted price of the Notes in an over-the-counter market (Level 2), and carrying value of debt instruments (carrying value excludes the equity component of the Company’s Notes classified in equity) were as follows: June 30, 2020 December 31, 2019 Fair Value Carrying Value Fair Value Carrying Value Convertible senior notes $ 184,800 $ 193,843 $ 207,600 $ 187,949 In connection with the issuance of the Notes, the Company entered into capped call transactions with certain counterparties affiliated with the initial purchasers and others. The capped call transactions are expected to reduce potential dilution of earnings per share upon conversion of the Notes. Under the capped call transactions, the Company purchased capped call options that in the aggregate relate to the total number of shares of the Company’s common stock underlying the Notes, with an initial strike price of approximately $53.17 per share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $89.98. The cost of the purchased capped calls of $33,024 was recorded to stockholders’ deficit and will not be re-measured provided it continues to meet the conditions for equity classification. Based on the closing price of our common stock of $10.76 on June 30, 2020, the last trading day of the quarter, the if-converted value of the Notes was less than their respective principal amounts. |
