February 2018 Notes

On February 12, 2014, the Company issued $300.0 million in aggregate principal amount, at par, of the February 2018 Notes in an underwritten public offering, for net proceeds of $290.2 million. The February 2018 Notes are due February 1, 2018, and the Company pays interest at 4.0% on the February 2018 Notes semiannually in arrears on February 1 and August 1 of each year, beginning August 1, 2014. A portion of the proceeds from the February 2018 Notes, net of amounts used for purchased call option transactions and provided by the warrant transactions described below, were used to redeem $131.7 million of the Company’s 2.975% Convertible Senior Notes due February 17, 2016. Upon the occurrence of a fundamental change, as defined in the indenture, holders have the option to require the Company to repurchase their February 2018 Notes at a purchase price equal to 100% of the principal, plus accrued interest.

On November 20, 2015, the Company’s agent initiated the repurchase of $53.6 million in aggregate principal amount of its February 2018 Notes for $43.7 million in cash in four open market transactions. The closing of these transactions occurred on November 30, 2015. It was determined that the repurchase of the principal amount shall be accounted for as a partial extinguishment of the February 2018 Notes. As a result, a gain on extinguishment of $6.5 million was recorded at closing of the transaction. The $6.5 million gain on extinguishment included the de-recognition of the original issuance discount of $3.1 million, outstanding deferred issuance costs of $0.9 million and agent fees of $0.1 million. Immediately following the repurchase, $246.4 million principal amount of the February 2018 Notes was outstanding with $14.1 million of remaining original issuance discount and $4.1 million of debt issuance costs to be amortized over the remaining life of the February 2018 Notes.

In connection with this repurchase of the February 2018 Notes, the Company unwound a portion of the purchased call options related to the notes. As a result of this unwinding, the Company received $0.3 million in cash. The payments received have been recorded as an increase to additional paid-in-capital. In addition, the Company unwound a portion of the warrants for $0.2 million in cash, payable by the Company. The payments have been recorded as a decrease to additional paid-in-capital. At the time of the transaction, the Company concluded that the remaining purchased call options and warrants continue to meet all criteria for equity classification.

On November 22, 2016, the Company repurchased $120.0 million in aggregate principal amount of its February 2018 Notes for approximately $121.5 million in cash (including $1.5 million of accrued interest) in open market transactions. It was determined that the repurchase of the principal amount shall be accounted for as an extinguishment. The extinguishment included the de-recognition of the original issuance discount of $4.3 million and outstanding deferred issuance costs of $1.3 million. Immediately following the repurchase, $126.4 million principal amount of the February 2018 Notes was outstanding with $4.6 million of remaining original issuance discount and $1.4 million of debt issuance costs to be amortized over the remaining life of the February 2018 Notes.

In connection with the repurchase of the February 2018 Notes, the Company unwound a portion of the purchased call options. The unwind transaction of the purchased call option did not result in any cash payments between the parties. In addition, the Company and the counterparties agreed to unwind a portion of the warrants, which also did not result in any cash payments between the parties. At the time of the transaction, the Company concluded that the remaining purchased call options and warrants continue to meet all criteria for equity classification.

The February 2018 Notes are convertible under any of the following circumstances:


•	During any fiscal quarter ending after the quarter ended June 30, 2014, if the last reported sale price of the Company’s common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter exceeds 130% of the conversion price for the notes on the last day of such preceding fiscal quarter;


•	During the five business-day period immediately after any five consecutive trading-day period in which the trading price per $1,000 principal amount of notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate for the notes for each such day;


•	Upon the occurrence of specified corporate events as described further in the indenture; or


•	At any time on or after August 1, 2017.

The initial conversion rate for the February 2018 Notes is 109.1048 shares of the Company’s common stock per $1,000 principal amount of February 2018 Notes, which is equivalent to an initial conversion price of approximately $9.17 per share of common stock, subject to adjustments upon the occurrence of certain specified events as set forth in the indenture. Upon conversion, the Company will be required to pay cash and, if applicable, deliver shares of the Company’s common stock as described in the indenture.

As of September 30, 2017, the Company’s February 2018 Notes are convertible. At September 30, 2017, the if-converted value of the February 2018 Notes did not exceed the principal amount.

In accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, the Company was required to separately account for the liability component of the instrument in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. As a result, the Company separated the principal balance of the February 2018 Notes between the fair value of the debt component and the fair value of the common stock conversion feature. Using an assumed borrowing rate of 7.0%, which represents the estimated market interest rate for a similar nonconvertible instrument available to the Company on the date of issuance, the Company recorded a total debt discount of $29.7 million, allocated $19.3 million to additional paid-in capital and allocated $10.4 million to deferred tax liability. The discount is being amortized to interest expense over the term of the February 2018 Notes and increases interest expense during the term of the February 2018 Notes from the 4.0% cash coupon interest rate to an effective interest rate of 6.9%. As of September 30, 2017, the remaining discount amortization period is 0.3 years.

The carrying value and unamortized discount of the February 2018 Notes were as follows:

Purchased Call Options and Warrants

In connection with the issuance of the February 2018 Notes, the Company entered into purchased call option transactions with two hedge counterparties. The Company paid an aggregate amount of $31.0 million for the purchased call options with terms substantially similar to the embedded conversion options in the February 2018 Notes. The purchased call options cover, subject to anti-dilution and certain other customary adjustments substantially similar to those in the February 2018 Notes, approximately 13.8 million shares of the Company’s common stock. The Company may exercise the purchased call options upon conversion of the February 2018 Notes and require the hedge counterparty to deliver shares to the Company in an amount equal to the shares required to be delivered by the Company to the note holder for the excess conversion value. The purchased call options expire on February 1, 2018, or the last day any of the February 2018 Notes remain outstanding.

In addition, the Company sold to the hedge counterparties warrants exercisable, on a cashless basis, for the sale of rights to receive shares of common stock that will initially underlie the February 2018 Notes at a strike price of $10.3610 per share, which represents a premium of approximately 30% over the last reported sale price of the Company’s common stock of $7.97 on February 6, 2014. The warrant transactions could have a dilutive effect to the extent that the market price of the Company’s common stock exceeds the applicable strike price of the warrants on the date of conversion. The Company received an aggregate amount of $11.4 million for the sale from the two counterparties. The warrant counterparties may exercise the warrants on their specified expiration dates that occur over a period of time. If the VWAP of the Company’s common stock, as defined in the warrants, exceeds the strike price of the warrants, the Company will deliver to the warrant counterparties shares equal to the spread between the VWAP on the date of exercise or expiration and the strike price. If the VWAP is less than the strike price, neither party is obligated to deliver anything to the other.

The purchased call option transactions and warrant sales effectively serve to reduce the potential dilution associated with conversion of the February 2018 Notes. The strike price is subject to further adjustment in the event that future quarterly dividends exceed $0.15 per share.

The purchased call options and warrants are considered indexed to the Company stock, require net-share settlement, and met all criteria for equity classification at inception and at September 30, 2017. The purchased call options cost of $31.0 million, less deferred taxes of $10.8 million, and the $11.4 million received for the warrants, was recorded as adjustments to additional paid-in capital. Subsequent changes in fair value will not be recognized as long as the purchased call options and warrants continue to meet the criteria for equity classification.

December 2021 Notes

On November 22, 2016, the Company issued $150.0 million in aggregate principal amount, at par, of the December 2021 Notes in an underwritten public offering, for net proceeds of $145.7 million. The December 2021 Notes are due December 1, 2021, and the Company pays interest at 2.75% on the December 2021 Notes semiannually in arrears on June 1 and December 1 of each year, beginning June 1, 2017. A portion of the proceeds from the December 2021 Notes was used to extinguish $120.0 million of the February 2018 Notes.

Upon the occurrence of a fundamental change, as defined in the indenture, holders have the option to require the Company to repurchase their December 2021 Notes at a purchase price equal to 100% of the principal, plus accrued interest.

The December 2021 Notes are convertible under any of the following circumstances:

•

During any fiscal quarter (and only during such fiscal quarter) commencing after the fiscal quarter ended June 30, 2017, if the last reported sale price of Company common stock for at least 20 trading days (whether or not consecutive), in the period of 30 consecutive trading days, ending on, and including, the last trading day of the immediately preceding fiscal quarter, exceeds 130% of the conversion price for the notes on each applicable trading day;

•

During the five business-day period immediately after any five consecutive trading-day period, which the Company refers to as the measurement period, in which the trading price per $1,000 principal amount of notes for each trading day of that measurement period was less than 98% of the product of the last reported sale price of Company common stock and the conversion rate for the notes for each such trading day; or


•	Upon the occurrence of specified corporate events as described in the indenture.

The initial conversion rate for the December 2021 Notes is 262.2951 shares of the Company’s common stock per $1,000 principal amount of December 2021 Notes, which is equivalent to an initial conversion price of approximately $3.81 per share of common stock, subject to adjustments upon the occurrence of certain specified events as set forth in the indenture.

In accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, the Company was required to separately account for the liability component of the instrument in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. As a result, the Company separated the principal balance of the December 2021 Notes between the fair value of the debt component and the fair value of the common stock conversion feature. Using an assumed borrowing rate of 9.5%, which represents the estimated market interest rate for a similar nonconvertible instrument available to us on the date of issuance, the Company recorded a total debt discount of $4.3 million, allocated $23.8 million to additional paid-in capital and allocated $12.8 million to deferred tax liability. The discount is being amortized to interest expense over the term of the December 2021 Notes and increases interest expense during the term of the December 2021 Notes from the 2.75% cash coupon interest rate to an effective interest rate of 3.4%. As of September 30, 2017, the remaining discount amortization period is 4.2 years.

The carrying value and unamortized discount of the December 2021 Notes were as follows:



(In thousands)	September 30, 2017			December 31, 2016
Principal amount of the December 2021 Notes	$	150,000		$	150,000
Unamortized discount of liability component	(34,284		)	(39,152		)
Net carrying value of the December 2021 Notes	$	115,716		$	110,848

As of September 30, 2017, the December 2021 Notes are not convertible. At September 30, 2017, the if-converted value of the December 2021 Notes did not exceed the principal amount.

Capped Call Transaction

In connection with the offering of the December 2021 Notes, the Company entered into a privately-negotiated capped call transaction with an affiliate of the underwriter of such issuance. The aggregate cost of the capped call transaction was $14.4 million. The capped call transaction is generally expected to reduce the potential dilution upon conversion of the December 2021 Notes and/or partially offset any cash payments the Company is required to make in excess of the principal amount of converted December 2021 Notes in the event that the market price per share of the Company’s common stock, as measured under the terms of the capped call transaction, is greater than the strike price of the capped call transaction. This initially corresponds to the approximate $3.81 per share conversion price of the December 2021 Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the December 2021 Notes. The cap price of the capped call transaction was initially $4.88 per share, and is subject to certain adjustments under the terms of the capped call transaction. The Company will not be required to make any cash payments to the option counterparty upon the exercise of the options that are a part of the capped call transaction, but the Company will be entitled to receive from it an aggregate amount of cash and/or number of shares of the Company’s common stock, based on the settlement method election chosen for the related convertible notes, with a value equal to the amount by which the market price per share of the Company’s common stock, as measured under the terms of the capped call transaction, is greater than the strike price of the capped call transaction during the relevant valuation period under the capped call transaction, with such number of shares of the Company’s common stock and/or amount of cash subject to the cap price.

The Company evaluated the capped call transaction under authoritative accounting guidance and determined that they should be accounted for as separate transactions and classified as a net reduction to additional paid-in capital within stockholders’ equity with no recurring fair value measurement recorded.
