Senior Secured Credit Facilities Agreement

On February 16, 2021, the Company entered into a Senior Secured Credit Facilities Agreement ("Credit Agreement") with Silicon Valley Bank ("SVB") for an aggregate commitment amount of $100.0 million with a maturity date of February 16, 2024. The Company recorded $0.6 million of debt issuance costs associated with the Credit Agreement in other assets on the Company's condensed consolidated balance sheet. The Credit Agreement bears interest at a rate per annum equal to the sum of LIBOR for the applicable interest period plus 1.75% - 2.00%, depending on the average daily outstanding balance of all loans and letters of credit under the Credit Agreement. Interest payments on outstanding borrowings are due on the last day of each interest period. The Credit Agreement has a commitment fee on the unused portion of the borrowing commitment, which is payable on the last day of each calendar quarter at a rate per annum of 0.20% - 0.25% depending on the average daily outstanding balance of all loans and letters of credit under the Credit Agreement. In addition, the Company's Credit Agreement contains a financial covenant that requires the Company to maintain a consolidated adjusted quick ratio of at least 1:25 to 1:00 tested on a quarterly basis as well as a springing revenue growth covenant for certain periods if the Company's consolidated adjusted quick ratio falls below 1.75 to 1:00 on the last day of any fiscal quarter. The Credit Agreement requires the Company to comply with these affirmative and negative covenants.

As of June 30, 2022, the Company was in compliance with all of its covenants. During the three and six months ended June 30, 2022 and 2021, no amounts were drawn down on the Company's Credit Agreement. As of June 30, 2022 and December 31, 2021, no amounts were outstanding under the Credit Agreement.

Convertible Senior Notes

On March 5, 2021, the Company issued approximately $948.8 million aggregate principal amount of the Company's 0% convertible senior notes due 2026 (the “Notes”), including the exercise in full by the initial purchasers of their option to purchase up to an additional approximately $123.8 million principal amount of the Notes. The Notes were issued in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Notes will mature on March 15, 2026, unless earlier converted, redeemed or repurchased. The net proceeds from the issuance of the Notes were approximately $930.0 million after deducting the initial purchasers’ discounts and transaction costs.

The Company may not redeem the Notes prior to March 20, 2024. On or after March 20, 2024, the Company may redeem for cash, all or any portion of the Notes, at the Company's option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of the Company's common stock has been at least 130% of the conversion price for the Notes 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 the Company provides notice of redemption. No sinking fund is provided for the Notes.

Holders of the Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding December 15, 2025, only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company's 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 calendar quarter is greater

than or equal to 130% of the conversion price for the Notes on each applicable trading day; (ii) during the five business day period after any ten consecutive trading day period (the “Measurement Period”) in which the trading price, as defined in the indenture agreement governing the Note filed with the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on March 5, 2021, 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 the Company's Class A common stock and the conversion rate on each such trading day; (iii) if the Company calls such Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the applicable redemption date, but only with respect to the Notes called (or deemed called) for redemption; or (iv) upon the occurrence of specified corporate events. On or after December 15, 2025 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 any time, regardless of the foregoing circumstances.

Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of its Class A common stock or a combination of cash and shares of its Class A common stock, at the Company's election. The initial conversion rate is 9.7272 shares of Class A common stock per $1,000 principal amount of Notes, equivalent to an initial conversion price of approximately $102.80 per share of Class A common stock. The conversion rate is subject to adjustment as described in the indenture governing the Notes but will not be adjusted for any accrued and unpaid special interest. In addition, following certain corporate events that occur prior to the maturity date of the Notes or if the Company delivers a notice of redemption in respect of the Notes, the Company will, in certain circumstances, increase the conversion rate of the Notes for a holder who elects to convert its Notes, in connection with such a corporate event or convert its Notes called (or deemed called) for redemption during the related redemption period, as the case may be.

The indenture includes customary covenants and sets forth certain events of default after which the Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the Notes become automatically due and payable. If the Company undergoes a fundamental change, as defined in the indenture agreement governing the Notes, then subject to certain conditions and except as described in the indenture governing the Notes, holders may require the Company to repurchase 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 special interest, if any, to, but excluding, the fundamental change repurchase date.

The Company evaluated the terms of its debt and concluded that the instrument does not require separation and that there were no other derivatives that required separation. As such, the Company has combined these features with the host contract and the Company accounts for its convertible debt as a single liability in long-term debt on its condensed consolidated balance sheet. The initial purchasers' discounts and transaction costs of $18.6 million incurred related to the issuance of the Notes were classified as liability and represents the difference between the principal amount of the Notes and the liability component (the “debt discount”), which is amortized to interest expense using the effective interest method over the term of the Notes.

As of June 30, 2022, the conversion conditions had not been met and therefore the Notes were not yet convertible.

On May 25, 2022, the Company entered into separate, privately negotiated transactions with certain holders of the Notes to repurchase (the “Repurchases”) approximately $235.0 million aggregate principal amount of the Notes for an aggregate cash repurchase price of approximately $176.4 million. The Repurchases closed on May 31, 2022. The Repurchases were accounted for as a debt extinguishment that resulted in a net gain of $54.4 million, which was recorded as non-operating income on the Company's condensed consolidated statement of operations in the three and six months ended June 30, 2022.

The following table reflects the carrying values of the debt agreements as of June 30, 2022 and December 31, 2021:
