In January 2021, we issued $345.0 million aggregate principal amount of 0.00% convertible senior notes due January 15, 2026. The Notes are senior unsecured obligations and do not bear regular interest. Each $1,000 principal amount of the Notes will initially be convertible into 38.7665 shares of our Class A common stock, which is equivalent to an initial conversion price of approximately $25.80 per share, subject to adjustment upon the occurrence of specified events.

The Notes are convertible at the option of the holders of the Notes at any time prior to the close of business on the business day immediately preceding October 15, 2025, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on April 30, 2021 (and only during such fiscal quarter), if the last reported sale price of our Class A 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 fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our Class A common stock and the conversion rate for the Notes on each such trading day; (3) if we call the Notes for redemption, 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.

On or after October 15, 2025, holders of the 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. Effective February 5, 2021, we have made an irrevocable election to settle the principal portion of the Notes only in cash. Accordingly, upon conversion, we will pay the principal portion in cash and we will pay or deliver, as the case may be, the conversion premium in cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election.

We may not redeem the Notes prior to January 20, 2024. We may redeem for cash all or any portion of the Notes, at our option, on or after January 20, 2024, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid special interest to, but excluding the redemption date. No sinking fund is provided for the Notes, which means we are not required to redeem or retire the Notes periodically.

Upon the occurrence of a fundamental change (as defined in the indenture governing the Notes) prior to the maturity date, subject to certain conditions, holders of the Notes may require us to repurchase all or a portion of the Notes for cash at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus any accrued and unpaid special interest to, but excluding, the fundamental change repurchase date.

As of January 31, 2021, the conditions allowing holders of the Notes to convert were not met.

In accounting for the issuance of the Notes, we separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Notes. The difference represents the debt discount that is amortized to interest expense over the term of the Notes using the effective interest rate method. The gross carrying amount of the equity component recorded was $70.5 million and was included in additional paid-in capital on the consolidated balance sheets upon issuance. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The effective interest rate of the liability component was 5.19%.

In accounting for the issuance costs related to the Notes, we allocated the total amount of issuance costs incurred to liability and equity components based on their relative values. Issuance costs attributable to the liability component are being amortized to interest expense over the term of the Notes using the effective interest rate method. The issuance costs attributable to the equity component were netted against the equity component in additional paid-in capital. Upon issuance of the Notes, we recorded liability issuance costs of $7.5 million and equity issuance costs of $1.9 million.

The net carrying amount of the liability component of the Notes consists of the following (in thousands):

	January 31,
	2021
Principal		345,000
Unamortized debt discount for conversion option		(69,916	)
Unamortized issuance costs		(7,470	)
Net carrying amount		267,614

The net carrying amount of the equity component of the Notes consists of the following (in thousands):

	January 31,
	2021
Debt discount for conversion option		70,509
Issuance costs		(1,933	)
Net carrying amount		68,576

For the year ended January 31, 2021, the interest expense recognized related to the Notes was $0.6 million.

In connection with the pricing of the Notes, we entered into privately negotiated capped call transactions with certain counterparties (Capped Calls). The Capped Calls each have an initial strike price of approximately $25.80 per share, subject to certain adjustments, which correspond to the initial conversion price of the Notes. The Capped Calls have initial cap prices of $35.58 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 13.4 million shares of our Class A common stock. Conditions that cause adjustments to the initial strike price of the Capped Calls are similar to the conditions that result in corresponding adjustments for the Notes. The Capped Calls are generally intended to reduce or offset the potential dilution to our common stock upon any conversion of the Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. The Capped Calls are separate transactions, and not part of the terms of the Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $27.8 million incurred in connection with the Capped Calls was recorded as a reduction to additional paid-in capital.

On November 27, 2017, we entered into a secured credit agreement (as amended or otherwise modified from time to time, the November 2017 Facility) and on July12, 2019, we entered into Amendment No.1 to the November 2017 Facility. Pursuant to the terms of the amendment, among other changes, (i) the maturity date of borrowings under the November 2017 Facility was extended from November 27, 2020 to July 12, 2022; (ii) the revolving commitments were increased from $85.0 million to $100.0 million; (iii) the sublimit for the issuance of letters of credit was increased from $30.0 million to $45.0 million; (iv) the covenant in the November 2017 Facility that limits the amount of finance leases and debt that we can incur to finance the acquisition, construction or improvement of any equipment or capital assets was increased from $100.0 million to $200.0 million; and (v) a clause for the issuance of debt constituting convertible debt securities was added, limiting the debt to an aggregate principal amount not to exceed the greater of (a) $350.0 million and (b) immediately after giving pro forma effect to the incurrence of such debt, an amount that would not cause the total leverage ratio to exceed 6.00 to 1.00. The total leverage ratio is defined in Amendment No. 1 as the ratio of (a) all outstanding funded debt to (b) earnings before

interest, taxes, depreciation, and amortization (EBITDA), as of the end of the twelve-month period most recently ended for which financial statements are available. The proceeds of the revolving loans may be used for general corporate purposes. The revolving loans accrue interest at a prime rate plus a margin of 0.25% or, at our option, a LIBOR rate (based on one, three or six-month interest periods) plus a margin of 1.00%. Interest on the revolving loans is payable quarterly in arrears with respect to loans based on the prime rate and at the end of an interest period in the case of loans based on the LIBOR rate (or at each three-month interval if the interest period is longer than three months). Borrowings under the November 2017 Facility are collateralized by substantially all of our assets. The November 2017 Facility requires us to comply with a maximum leverage ratio and a minimum liquidity requirement. Additionally, the November 2017 Facility contains customary affirmative and negative covenants, including covenants limiting our, and our subsidiaries’, ability to, among other things, grant liens, incur debt, pay dividends or distributions on the capital stock, effect certain mergers, make investments, dispose of assets, incur contractual obligations and commitments and enter into transactions with affiliates, in each case subject to customary exceptions for a credit facility of the size and type of the November 2017 Facility.

In April 2020, we drew an additional $30.0 million on the November 2017 Facility. During the year ended January 31, 2021, we paid down $40.0 million, of which $20.0 million was paid down in October 2020 and $20.0 million was paid down in January 2021, on our outstanding principal balance on the November 2017 Facility. As of January 31, 2021, we had total debt outstanding relating to the November 2017 Facility with a carrying amount of $30.0 million.

In connection with the November 2017 Facility, for the years ended January 31, 2021, 2020 and 2019, we incurred interest expense, net of capitalized interest costs, of $1.1 million, $1.3 million, and $1.3 million, respectively. During the same periods, the amounts of interest capitalized were not material. Interest expense in connection with the November 2017 Facility includes interest charges for our line of credit, amortization of issuance costs, and unused commitment fees on our line of credit.
