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.

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 April 30, 2021, the conditions allowing holders of the Notes to convert were not met.

	April 30,			January 31,
	2021			2021
Principal	$	345,000		$	345,000
Unamortized debt discount for conversion option		—			(69,916	)
Unamortized issuance costs		(8,939	)		(7,470	)
Net carrying amount	$	336,061		$	267,614

Issuance costs are being amortized to interest expense over the term of the Notes using the effective interest rate method. The effective interest rate used to amortize the issuance costs was 0.56%. For the three months ended April 30, 2021, the interest expense recognized related to the Notes was $0.5 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). The maturity date of borrowings under the November 2017 Facility is July 12, 2022, the revolving commitment is $100.0 million, and it provides for a sublimit for the issuance of letters of credit of $45.0 million. The November 2017 Facility limits the amount of finance leases and debt that we can incur to $200.0 million, and allows for the issuance of debt constituting convertible debt securities of $350.0 million so long as the total leverage ratio does not exceed 6.00 to 1.00. 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%. 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.

As of April 30, 2021, we had total debt outstanding with a carrying amount of $30.0 million and we were in compliance with all financial covenants.

In association with our November 2017 Facility, we are required to make variable rate interest payments based on a contractually specified interest rate index (e.g., LIBOR). The variable rate interest payments create interest rate risk as interest payments will fluctuate based on changes in the contractually specified interest rate index over the life of the loan. To minimize our risk exposure due to the volatility of the interest rate index, we entered into an interest rate swap agreement with Wells Fargo Bank, National Association, effective as of September 5, 2019 (Swap Agreement). This agreement, which is designated as a cash flow hedge, has a maturity of five years. Under the Swap Agreement, we have hedged a portion of the variable interest payments by effectively fixing our interest payments over the term of the agreement. As of April 30, 2021, our interest rate swap had a notional value of $30.0 million.
