The 3.75% Convertible Senior Notes bear interest at a  rate of 3.75% per year, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The notes will mature on June 1, 2025, unless earlier converted, redeemed or repurchased in accordance with their terms.

The 3.75% Convertible Senior Notes are senior, unsecured obligations of the Company and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the notes, equal in

right of payment to any of the Company’s existing and future liabilities that are not so subordinated, including the Company’s $100 million in aggregate principal amount of the 5.5% Convertible Senior Notes due 2023, which is referred to herein as the 5.5% Convertible Senior Notes, effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all indebtedness and other liabilities, including trade payables, of its current or future subsidiaries.

Holders of the 3.75% Convertible Senior Notes may convert their notes at their option at any time prior to the close of the business day immediately preceding December 1, 2024 in the following circumstances:

1)

during any calendar quarter commencing after December 31, 2020, if the last reported sale price of the Company’s common stock exceeds 130% of the conversion price for each of 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;

2)

during the five business days after any five consecutive trading day period (such five consecutive trading day period, the measurement period) in which the trading price per $1,000 principal amount of the 3.75% Convertible Senior Notes for each trading day of the 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;

3)

if the Company calls any or all of the 3.75% Convertible Senior Notes for redemption, any such notes that have been called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

4)

upon the occurrence of specified corporate events, as described in the indenture governing the 3.75% Convertible Senior Notes.

On or after December 1, 2024, the holders of the 3.75% Convertible Senior Notes may convert all or any portion of their notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions.

The initial conversion rate for the 3.75% Convertible Senior Notes is 198.6196 shares of the Company’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $5.03 per share of the Company’s common stock, subject to adjustment upon the occurrence of specified events. Upon conversion, the Company will pay or deliver, as applicable, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. During January and February of 2021, $15.2 million of the 3.75% Convertible Senior Notes have been converted and the Company has issued 3.0 million shares in conjunction with these conversions.

In addition, following certain corporate events or following issuance of a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called for redemption during the related redemption period in certain circumstances.

The 3.75% Convertible Senior Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after June 5, 2023 and before the 41st scheduled trading day immediately before the maturity date, at a cash redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including at least one of the three trading days immediately preceding the date the Company sends the related redemption notice, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company sends such redemption notice.

If the Company undergoes a “fundamental change” (as defined in the Indenture), holders may require the Company to repurchase their notes for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the 3.75% Convertible Senior Notes, the Company separated the notes into liability and equity components. The initial carrying amount of the liability component of approximately $75.2 million, net of costs incurred, was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component of approximately $130.3 million, net of costs incurred, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 3.75% Convertible Senior Notes. The difference between the principal amount of the 3.75% Convertible Senior Notes and the liability component (the debt discount) is amortized to interest expense using the effective interest method over the term of the 3.75% Convertible Senior Notes. The effective interest rate is approximately 29.0%. The equity component of the 3.75% Convertible Senior Notes is included in additional paid-in capital in the consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification.

We incurred transaction costs related to the issuance of the 3.75% Convertible Senior Notes of approximately $7.0 million, consisting of initial purchasers’ discount of approximately $6.4 million and other issuance costs of $0.6 million. In accounting for the transaction costs, we allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds from the 3.75% Convertible Senior Notes. Transaction costs attributable to the liability component were approximately $2.6 million, were recorded as debt issuance cost (presented as contra debt in the consolidated balance sheets) and are being amortized to interest expense over the term of the 3.75% Convertible Senior Notes. The transaction costs attributable to the equity component were approximately $4.4 million and were netted with the equity component in stockholders’ equity.

Based on the closing price of the Company’s common stock of $33.91 on December 31, 2020, the if-converted value of the notes was greater than the principal amount. The estimated fair value of the note at December 31, 2020 was approximately $1.3 billion. Fair value estimation was primarily based on a stock exchange, active trade on December 29, 2020 of the 3.75%  Senior Convertible Note. The Company considers this a Level 1 fair value measurement. Refer to Note 4, “Summary of Significant Accounting Policies.”

Capped Call

In conjunction with the pricing of the 3.75% Convertible Senior Notes, the Company entered into privately negotiated capped call transactions (the “3.75% Notes Capped Call”) with certain counterparties at a price of $16.2 million.

The 3.75% Notes Capped Call covers, subject to anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that underlie the initial 3.75% Convertible Senior Notes and is generally expected to reduce potential dilution to the Company’s common stock upon any conversion of the 3.75% Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The cap price of the 3.75% Notes Capped Call is initially $6.7560 per share, which represents a premium of approximately 60% over the last then-reported sale price of the Company’s common stock of $4.11 per share on the date of the transaction and is subject to certain adjustments under the terms of the 3.75% Notes Capped Call. The 3.75% Notes Capped Call becomes exercisable if the conversion option is exercised.

The net cost incurred in connection with the 3.75% Notes Capped Call has been recorded as a reduction to additional paid-in capital in the consolidated balance sheet.

7.5% Convertible Senior Note

In September 2019, the Company issued $40.0 million aggregate principal amount of 7.5%  Convertible Senior Note due on January 5, 2023, which is referred to herein as the 7.5% Convertible Senior Note, in exchange for net proceeds of $39.1 million, in a private placement to an accredited investor pursuant to Rule 144A under the Securities Act. There were no required principal payments prior to the maturity of the 7.5% Convertible Senior Note. Upon maturity of the 7.5% Convertible Senior Note, the Company was required to repay 120% of $40.0 million, or $48.0 million. The 7.5% Convertible Senior Note bore interest at 7.5% per year, payable quarterly in arrears on January 5, April 5, July 5 and October 5 of each year beginning on October 5, 2019 and was to mature on January 5, 2023 unless earlier converted or repurchased in accordance with its terms. The 7.5% Convertible Senior Note was unsecured and did not contain any financial covenants or any restrictions on the payment of dividends, or the issuance or repurchase of common stock by the Company.

On July 1, 2020, the 7.5% Convertible Senior Note automatically converted into 16.0 million shares of common stock.

5.5% Convertible Senior Notes

In March 2018, the Company issued $100 million in aggregate principal amount of the 5.5% Convertible Senior Notes due on March 15, 2023, which is referred to herein as the 5.5% Convertible Senior Notes, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act.

In May 2020, the Company used a portion of the net proceeds from the issuance of the 3.75% Convertible Senior Notes to finance the cash portion of the partial repurchase of the 5.5% Convertible Senior Notes, which consisted of a repurchase of approximately $66.3 million in aggregate principal amount of the 5.5% Convertible Senior Notes in privately-negotiated transactions for aggregate consideration of $128.9 million, consisting of approximately $90.2 million in cash and approximately 9.4 million shares of the Company’s common stock. Of the $128.9 million in aggregate consideration, $35.5 million and $93.4 million were allocated to the debt and equity components, respectively, utilizing an effective discount rate of 29.8% to determine the fair value of the liability component. As of the repurchase date, the carrying value of the 5.5% Convertible Senior Notes that were repurchased, net of unamortized debt discount and issuance costs, was $48.7 million. The partial repurchase of the 5.5% Convertible Senior Notes resulted in a $13.2 million gain on early debt extinguishment. In the fourth quarter of 2020, $33.5 million of the remaining 5.5% Convertible Senior Notes converted into 14.6 million shares of common stock which resulted in a gain of approximately $4.5 million which was recorded on the consolidated statement of operations on the gain (loss) on extinguishment of debt line. As of December 31, 2020, approximately $160 thousand aggregate principal amount of the 5.5% Convertible Senior Notes remained outstanding, all of which were converted into common stock  in January 2021.

In accounting for the issuance of the notes, the Company separated the 5.5% Convertible Senior Notes into liability and equity components. The initial carrying amount of the liability component of approximately $58.2 million,

net of costs incurred, was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component of approximately $37.7 million, net of costs incurred, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 5.5% Convertible Senior Notes. The difference between the principal amount of the 5.5% Convertible Senior Notes and the liability component (the debt discount) is amortized to interest expense using the effective interest method over the term of the 5.5% Convertible Senior Notes. The effective interest rate is approximately 16.0%. The equity component of the 5.5% Convertible Senior Notes is included in additional paid-in capital in the consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification.

We incurred transaction costs related to the issuance of the 5.5% Convertible Senior Notes of approximately $4.1 million, consisting of initial purchasers’ discount of approximately $3.3 million and other issuance costs of $0.9 million. In accounting for the transaction costs, we allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds from the 5.5% Convertible Senior Notes. Transaction costs attributable to the liability component were approximately $2.4 million, were recorded as debt issuance cost (presented as contra debt in the consolidated balance sheets) and are being amortized to interest expense over the term of the 5.5% Convertible Senior Notes. The transaction costs attributable to the equity component were approximately $1.7 million and were netted with the equity component in stockholders’ equity.

Capped Call

In conjunction with the pricing of the 5.5% Convertible Senior Notes, the Company entered into privately negotiated capped call transactions (the “5.5% Notes Capped Call”) with certain counterparties at a price of $16.0 million. The 5.5% Notes Capped Call covers, subject to anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that underlie the initial 5.5% Convertible Senior Notes and is generally expected to reduce the potential dilution to the Company’s common stock upon any conversion of the 5.5% Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted 5.5% Convertible Senior Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The cap price of the 5.5% Notes Capped Call is initially $3.82 per share, which represents a premium of 100% over the last then-reported sale price of the Company’s common stock of $1.91 per share on the date of the transaction and is subject to certain adjustments under the terms of the 5.5% Notes Capped Call. The 5.5% Notes Capped Call becomes exercisable if the conversion option is exercised.

The net cost incurred in connection with the 5.5% Notes Capped Call has been recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

In conjunction with the partial repurchase of the 5.5% Convertible Senior Notes, the Company terminated 100% of the 5.5% Notes Capped Call on June 5, 2020. As a result of the termination, the Company received $24.2 million which was recorded in additional paid-in capital.

Common Stock Forward

In connection with the issuance of the 5.5% Convertible Senior Notes, the Company also entered into a forward stock purchase transaction, or the Common Stock Forward, pursuant to which the Company agreed to purchase 14,397,906 shares of its common stock for settlement on or about March 15, 2023. In connection with the issuance of the 3.75% Convertible Senior Notes and the partial payoff of the 5.5% Convertible Senior Notes, the Company amended and extended the maturity of the Common Stock Forward to June 1, 2025. The number of shares of common stock that the Company will ultimately repurchase under the Common Stock Forward is subject to customary anti-dilution adjustments. The Common Stock Forward is subject to early settlement or settlement with alternative consideration in the event of certain corporate transactions.

The net cost incurred in connection with the Common Stock Forward of $27.5 million has been recorded as an increase in treasury stock in the consolidated balance sheets. The related shares were accounted for as a repurchase of common stock.

The book value of the Common Stock Forward is not remeasured.

During the fourth quarter of 2020, the Common Stock Forward was partially settled and, as a result, the Company received 4.4 million shares of its common stock.
