Debt Disclosure [Abstract] |
CONVERTIBLE SENIOR NOTES | CONVERTIBLE SENIOR NOTES In January 2018, we issued Convertible Senior Notes with a 0% interest rate for an aggregate principal amount of $575.0 million, due in 2023 (the "Notes"), in a private placement to qualified institutional buyers pursuant to Rule144A under the Securities Act of 1933, as amended. This included $75.0 million in aggregate principal amount of the Notes that we issued resulting from initial purchasers fully exercising their option to purchase additional notes. There are no required principal payments prior to the maturity of the Notes. The total net proceeds from the Notes are as follows:
| Amount
| (in thousands)
Principal amount | $ | 575,000 |
Less: initial purchasers' discount | (10,781 | )
Less: cost of the bond hedges | (143,175 | )
Add: proceeds from the sale of warrants | 87,975 |
Less: other issuance costs | (707 | )
Net proceeds | $ | 508,312 |
The Notes do not bear any interest and will mature on January 15, 2023, unless earlier converted or repurchased in accordance with their terms. The Notes are unsecured and do not contain any financial covenants or any restrictions on the payment of dividends, or the issuance or repurchase of securities by us. Each $1,000 of principal of the Notes will initially be convertible into 20.4705 shares of our Class A common stock, which is equivalent to an initial conversion price of approximately $48.85 per share, subject to adjustment upon the occurrence of specified events. Holders of these Notes may convert their Notes at their option at any time prior to the close of the business day immediately preceding October 15, 2022, only under the following circumstances:
1) | during any fiscal quarter commencing after the fiscal quarter ending on April 30, 2018 (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; or
3) | upon the occurrence of certain specified corporate events.
Based on the closing price of our Class A common stock of $43.19 on April 30, 2019, the if-converted value of the Notes was lower than the principal amount. The price of our Class A common stock was not greater than or equal to 130% of the conversion price for 20 or more trading days during the 30 consecutive trading days ending on the last trading day of the quarter ended April 30, 2019, the Notes are not convertible for the fiscal quarter commencing after April 30, 2019. On or after October 15, 2022, holders 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. Upon conversion of the Notes, we will pay or deliver, as the case may be, cash, shares of our Class A common stock or a combination of cash and shares of Class A common stock, at our election. We intend to settle the principal of the Notes in cash. The conversion rate will be subject to adjustment in some events, but will not be adjusted for any accrued or unpaid interest. A holder who converts their Notes in connection with certain corporate events that constitute a "make-whole fundamental change" per the indenture governing the Notes are, under certain circumstances, entitled to an increase in the conversion rate. In addition, if we undergo a fundamental change prior to the maturity date, holders may require us to repurchase for cash all or a portion of their Notes at a repurchase price equal to 100% of the principal amount of the repurchased Notes, plus accrued and unpaid interest. We may not redeem the Notes prior to the maturity date, and no sinking fund is provided for the Notes. In accounting for the issuance of the Notes, we separated the Notes into liability and equity components. The carrying amount of the liability component of approximately $423.4 million 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 $151.6 million, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the liability component (the "debt discount") is amortized to interest expense using the effective interest method over the term of the Notes. The equity component of the Notes is included in additional paid-in capital in the condensed 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 Notes of approximately $11.5 million, consisting of an initial purchasers' discount of $10.8 million and other issuance costs of approximately $0.7 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 Notes. Transaction costs attributable to the liability component were approximately $8.5 million, recorded as debt issuance costs (presented as contra debt in the condensed consolidated balance sheets), and are being amortized to interest expense over the term of the Notes. The transaction costs attributable to the equity component were approximately $3.0 million and were net with the equity component within stockholders’ equity. The Notes consisted of the following:
| As of
| July 31, 2018 |  | April 30, 2019
| (in thousands)
Principal amounts: |  |  |
Principal | $ | 575,000 |  |  | $ | 575,000 |
Unamortized debt discount (1) | (137,719 | ) |  | (117,070 | )
Unamortized debt issuance costs (1) | (7,683 | ) |  | (6,531 | )
Net carrying amount | $ | 429,598 |  |  | $ | 451,399 |
Carrying amount of equity component (2) | $ | 148,598 |  |  | $ | 148,598 |
(1) | Included in the condensed consolidated balance sheets within convertible senior notes, net and amortized over the remaining life of the Notes using the effective interest rate method. The effective interest rate is 6.62%.
(2) | Included in the condensed consolidated balance sheets within additional paid-in capital, net of $3.0 million in equity issuance costs.
As of April 30, 2019, the remaining life of the Notes was approximately 44 months. The following table sets forth the total interest expense recognized related to the Notes:
| Three Months Ended April 30, |  | Nine Months Ended April 30,

| (in thousands)
Interest expense related to amortization of debt discount | $ | 6,550 |  |  | $ | 6,997 |  |  | $ | 7,250 |  |  | $ | 20,650 |
Interest expense related to amortization of debt issuance costs | 366 |  |  | 390 |  |  | 404 |  |  | 1,152 |
Total interest expense | $ | 6,916 |  |  | $ | 7,387 |  |  | $ | 7,654 |  |  | $ | 21,802 |
Note Hedges and Warrants Concurrently with the offering of the Notes in January 2018, we entered into convertible note hedge transactions with certain bank counterparties, whereby we have the initial option to purchase a total of approximately 11.8 million shares of our Class A common stock at a conversion price of approximately $48.85 per share, subject to adjustment for certain specified events. The total cost of the convertible note hedge transactions was approximately $143.2 million. In addition, we sold warrants to certain bank counterparties, whereby the holders of the warrants have the initial option to purchase a total of approximately 11.8 million shares of our Class A common stock at a price of $73.46 per share, subject to adjustment for certain specified events. We received approximately $88.0 million in cash proceeds from the sale of these warrants. Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset any actual dilution from the conversion of the Notes and to effectively increase the overall conversion price from $48.85 to $73.46 per share. As these transactions meet certain accounting criteria, the convertible note hedges and warrants are recorded within stockholders’ equity and are not accounted for as derivatives. The net cost incurred in connection with the convertible note hedge and warrant transactions of approximately $55.2 million was recorded as a reduction to additional paid-in capital in the condensed consolidated balance sheets as of July 31, 2018 and April 30, 2019. The fair value of the note hedges and warrants are not remeasured each reporting period. The amounts paid for the note hedges are tax deductible expenses, while the proceeds received from the warrants are not taxable. Impact to Earnings per Share The Notes will have no impact to diluted earnings per share ("EPS") until they meet the criteria for conversion, as discussed above, as we intend to settle the principal amount of the Notes in cash upon conversion. Under the treasury stock method, in periods when we report net income, we are required to include the effect of additional shares that may be issued under the Notes when the price of our Class A common stock exceeds the conversion price. Under this method, the cumulative dilutive effect of the Notes would be approximately 3.9 million shares if the average price of our Class A common stock was $73.46. However, upon conversion, there will be no economic dilution from the Notes, as exercise of the note hedges eliminate any dilution that would have otherwise occurred. The note hedges are required to be excluded from the calculation of diluted earnings per share, as they would be antidilutive under the treasury stock method. The warrants will have a dilutive effect when the average share price exceeds the warrant strike price of $73.46 per share. As the price of our Class A common stock continues to increase above the warrant strike price, additional dilution would occur at a declining rate so that a $10 increase from the warrant strike price would yield a cumulative dilution of approximately 4.9 million diluted shares for EPS purposes. However, upon conversion, the note hedges would neutralize the dilution from the Notes so that there would only be dilution from the warrants, which would result in an actual dilution of approximately 1.4 million shares at a common stock price of $83.46.
