Debt Disclosure [Abstract] |
Convertible Senior Notes | Convertible Senior Notes In September 2018, we issued $575.0 million aggregate principal amount of 0.5% Convertible Senior Notes due in 2023 (the Notes), including the initial purchasers’ exercise in full of their option to purchase an additional $75.0 million principal amount of the Notes, in a private placement to qualified institutional buyers in an offering exempt from registration under the Securities Act. The net proceeds from the issuance of the Notes were $560.8 million after deducting the initial purchasers’ discounts and transaction costs. The Notes are governed by an indenture (the “Indenture”) between us, as the issuer, and U.S. Bank National Association, as trustee. The Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our unsecured indebtedness then existing and future liabilities that are not so subordinated; effectively junior in right of payment to any of our secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The Indenture does not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by us or any of our subsidiaries. The Notes mature on September 15, 2023 unless earlier repurchased or redeemed by us or earlier converted in accordance with their terms prior to the maturity date. Interest is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2019. The Notes have an initial conversion rate of 13.9860 shares of our common stock per $1,000 principal amount of Notes, which is equal to an initial conversion price of approximately $71.50 per share of our common stock and is subject to adjustment in some events. Following certain corporate events that occur prior to the maturity date or following our issuance of a notice of redemption, we will increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or during the related redemption period in certain circumstances. Additionally, upon the occurrence of a corporate event that constitutes a “fundamental change” per the Indenture, holders of the Notes may require us to repurchase for cash all or a portion of their Notes at a purchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest. On or after June 15, 2023, until the close of business on September 13, 2023, holders may convert all or any portion of their Notes at any time regardless of whether the conditions set forth below have been met. Upon conversion, holders will receive cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. Holders of the Notes may convert all or any portion of their Notes at any time prior to the close of business on June 14, 2023, in integral multiples of $1,000 principal amount, only under the following circumstances:
• | During any fiscal quarter commencing after the fiscal quarter ending on January 31, 2019 (and only during such fiscal quarter), if the last reported sale price of our 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;
• | During the 5-business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price as defined in the Indenture 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 common stock and the conversion rate on each such trading day;
• | If we call any or all of the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or
• | Upon the occurrence of specified corporate events described in the Indenture.
We may redeem for cash or shares all or any portion of the Notes, at our option, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, beginning on or after September 20, 2021 if the last reported sale price of our 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. As of April 30, 2019, the conditions allowing holders of the Notes to convert have not been met and therefore the Notes are not yet convertible. We account for the Notes as separate liability and equity components. We determined the carrying amount of the liability component as the present value of its cash flows using a discount rate of 6% based on comparable convertible transactions for similar companies. The carrying amount of the equity component representing the conversion option was $134.7 million and was calculated by deducting the carrying value of the liability component from the principal amount of the Notes as a whole. This difference represents a debt discount that is amortized to interest expense over the term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. We allocate transaction costs related to the issuance of the Notes to the liability and equity components using the same proportions as the initial carrying value of the Notes. Transaction costs attributable to the liability component were $10.9 million and are being amortized to interest expense using the effective interest method over the term of the Notes. Transaction costs attributable to the equity component were $3.3 million and are netted with the equity component of the Notes in stockholders’ equity. The net carrying value of the liability component of the Notes was as follows:
(in thousands) | April 30, 2019
Principal | $ | 575,000 |
Less: unamortized debt discount | (119,903 | )
Less: unamortized transaction costs | (9,712 | )
Net carrying amount | $ | 445,385 |
The net carrying amount of the equity component of the Notes was as follows:
(in thousands) | April 30, 2019
Proceeds allocated to the conversion option (debt discount) | $ | 134,667 |
Less: transaction costs | (3,336 | )
Net carrying amount | $ | 131,331 |
The interest expense recognized related to the Notes was as follows:
(in thousands) | Three Months Ended April 30, 2019
Contractual interest expense | $ | 710 |
Amortization of debt discount | 484 |
Amortization of transaction costs | 5,970 |
Total | $ | 7,164 |
Capped Calls In connection with the offering of the Notes, we entered into privately-negotiated capped call transactions ("Capped Calls") with certain counterparties. The Capped Calls each have an initial strike price of approximately $71.50 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have initial cap prices of $110.00 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 8.0 million shares of our common stock. 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. As the Capped Call transactions are considered indexed to our own stock and are considered equity classified, they are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $67.6 million incurred in connection with the Capped Calls was recorded as a reduction to additional paid-in capital. Impact on Earnings Per Share The Notes will not have an impact on our diluted earnings per share until the average market price of our common stock exceeds the cap price of $110.00 per share, as we intend and have the ability to settle the principal amount of the Notes in cash upon conversion. We are required under the treasury stock method to compute the potentially dilutive shares of common stock related to the Notes for periods we report net income. However, upon conversion, there will be no economic dilution from the Notes until the average market price of our common stock exceeds the cap price of $110.00 per share, as exercise of the Capped Calls offsets any dilution from the Notes from the conversion price up to the cap price. Capped Calls are excluded from the calculation of diluted earnings per share, as they would be antidilutive under the treasury stock method.
