Series 2012 Notes

In January 2012, the Company issued and exchanged $169.0 million aggregate principal of new Series 2012 Notes for an identical principal amount of the February 2015 Notes, plus a cash payment of $5.00 for each $1,000 principal amount tendered, totaling approximately $845,000. The cash payment was allocated to deferred issue costs of $765,000, additional paid-in capital of $52,000 and deferred tax assets of $28,000. The deferred issue costs were recognized over the life of the Series 2012 Notes as interest expense. In February 2012, the Company entered into separate privately negotiated exchange agreements under which the Company issued and exchanged an additional $10.0 million aggregate principal amount of the Series 2012 Notes for an identical principal amount of the February 2015 Notes. In August 2013, the Company entered into a separate privately negotiated exchange agreement under which it retired the final $1.0 million aggregate principal amount of the outstanding February 2015 Notes. Pursuant to the exchange agreement, the holder of the February 2015 Notes received $1.0 million aggregate principal amount of the Series 2012 Notes. Immediately following the exchange, no principal amount of the February 2015 Notes remained outstanding and $180.0 million principal amount of the Series 2012 Notes is outstanding.

On February 6, 2014, the Company entered into exchange and purchase agreements with certain holders of approximately $131.7 million aggregate principal amount of outstanding Series 2012 Notes. The exchange agreement provided for the issuance by the Company of shares of common stock and a cash payment for the Series 2012 Notes being exchanged, and the purchase agreement provided for a cash payment for the Series 2012 Notes being repurchased. The total consideration given was approximately $191.8 million. The Company issued to the participating holders of the Series 2012 Notes a total of approximately 20.3 million shares of its common stock with a fair value of approximately $157.6 million and made an aggregate cash payment of approximately $34.2 million pursuant to the exchange and purchase agreements. Of the $34.2 million cash payment, $2.5 million is attributable to an inducement fee, $1.8 million is attributable to interest accrued through the date of settlement and $29.9 million is attributable to the repurchase of the Series 2012 Notes. It was determined that the exchange and purchase agreement represented an extinguishment of the related notes. As a result, a loss on extinguishment of $6.1 million was recorded. The $6.1 million loss on extinguishment included the de-recognition of the original issuance discount of $5.8 million and a $0.3 million charge resulting from the difference of the face value of the notes and the fair value of the notes. Immediately following the exchange, $48.3 million principal amount of the Series 2012 Notes was outstanding with approximately $2.1 million of remaining original issuance discount that was amortized over the remaining life of the Series 2012 Notes.

On October 20, 2014, the Company entered into a privately negotiated exchange agreement under which it retired approximately $26.0 million in principal of the outstanding Series 2012 Notes. The exchange agreement provided for the issuance, by the Company, of shares of common stock and a cash payment for the Series 2012 Notes being exchanged. The Company issued approximately 1.8 million shares of its common stock and paid a cash payment of approximately $26.2 million. Immediately following the exchange, $22.3 million principal amount of the Series 2012 Notes was outstanding with approximately $0.1 million of remaining original issuance discount to be amortized over the remaining life of the Series 2012 Notes.

The Series 2012 Notes were due February 17, 2015, and bore interest at a rate of 2.875% per annum, payable semi-annually in arrears on February 15 and August 15 of each year. On February 17, 2015, the Company retired the remaining $22.3 million of aggregate principal of its Series 2012 notes at their stated maturity for $22.3 million, plus approximately 1.34 million shares of its common stock.

Interest expense for the Series 2012 Notes on the Company’s Consolidated Statements of Income was as follows:

May 2015 Notes

On May 16, 2011, the Company issued $155.3 million in aggregate principal amount, at par, of the May 2015 Notes in an underwritten public offering, for net proceeds of $149.7 million. The May 2015 Notes were due May 1, 2015, and the Company paid interest at 3.75% on the May 2015 Notes semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2011. Proceeds from the May 2015 Notes, net of amounts used for purchased call option transactions and provided by the warrant transactions described below, were used to redeem the Series 2012 Notes.

On May 1, 2015, the Company retired of the remaining $155.1 million of aggregate principal of its May 2015 Notes at their stated maturity for $155.1 million, plus approximately 5.2 million shares of its common stock for the excess conversion value.

Purchased Call Options and Warrants

In connection with the issuance of the May 2015 Notes, the Company entered into purchased call option transactions with two hedge counterparties. The Company paid an aggregate amount of $20.8 million, plus legal fees, for the purchased call options with terms substantially similar to the embedded conversion options in the May 2015 Notes. The Company exercised the purchased call options upon conversion of the May 2015 Notes on May 1, 2015, which required the hedge counterparties to deliver shares to the Company. The hedge counterparties delivered approximately 5.2 million shares of the Company’s common stock to the Company, which was the amount equal to the shares required to be delivered by the Company to the note holders for the excess conversion value.

In addition, the Company sold to the hedge counterparties warrants exercisable, on a cashless basis, for the sale of rights to receive up to 27.5 million shares of common stock underlying the May 2015 Notes. The Company received an aggregate amount of $10.9 million for the sale from the two counterparties. Under the terms of the warrant agreement, the warrant counterparties had the option to exercise the warrants on their specified expiration dates through the 120 scheduled trading days beginning on July 30, 2015 and ended on January 20, 2016. Because the VWAP of the Company’s common stock never exceeded the strike price of the warrants, the Company did not deliver any common stock to the warrant counterparties.

The purchased call option transactions and warrant sales effectively served to reduce the potential dilution associated with conversion of the May 2015 Notes.

Because the share price was above $5.72 but below $6.73, upon conversion of the Company’s May 2015 Notes, the purchased call options offset the share dilution, and the Company received shares on exercise of the purchased call options equal to the shares that the Company delivered to the note holders.

While the purchased call options reduced the potential equity dilution upon conversion of the May 2015 Notes, prior to the conversion or exercise, the May 2015 Notes and the warrants had a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock during a given measurement period exceeds the respective exercise prices of those instruments.

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 Series 2012 Notes. 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 the repurchase of the February 2018 Notes, the Company and the counterparties agreed to unwind a portion of the purchased call options. As a result of the unwind transaction of the purchased call option, the Company received $270,000 in cash. The payments received have been recorded as an increase to APIC. In addition, the Company and the counterparties agreed to unwind a portion of the warrants for $170,000 in cash, payable by the Company. The payments have been recorded as a decrease to APIC. At December 31, 2015, 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. As of December 31, 2016, our February 2018 Notes are not convertible. At December 31, 2016, the if-converted value of our February 2018 Notes did not exceed the principal amount.

In connection with the repurchase of the February 2018 Notes, the Company and the counterparties agreed to unwind 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 December 31, 2016, the Company concluded that the remaining purchased call options and warrants continue to meet all criteria for equity classification.

As of December 31, 2016, the February 2018 Notes are not convertible. At December 31, 2016, the if-converted value of the February 2018 Notes did not exceed the principal amount.

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


•	During any fiscal quarter ending after the quarter ending 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, 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 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.

In accordance with the accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, the Company 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 us 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 December 31, 2016, the remaining discount amortization period is 1.1 years.

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



(In thousands)	December 31, 2016			December 31, 2015
Principal amount of the February 2018 Notes	$	126,447		$	246,447

As of December 31, 2016, 2015 and 2014, the February 2018 Notes are not convertible. At December 31, 2016, 2015 and 2014, the if-converted value of the February 2018 Notes did not exceed the principal amount.

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 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 December 31, 2016 and 2015. 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, net of amounts used for capped call transaction described below, were 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 ending March 31, 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 December 31, 2016, the remaining discount amortization period is 4.9 years.

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



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

Interest expense for the December 2021 Notes on the Company’s Consolidated Statements of Income was as follows:

As of December 31, 2016, the December 2021 Notes are not convertible. At December 31, 2016, the if-converted value of the December 2021 Notes did not exceed the principal amount.

Capped Call Transaction

In conjunction 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, which 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.

March 2015 Term Loan

On March 30, 2015, the Company entered into a credit agreement among the Company, the lenders party thereto and the Royal Bank of Canada, as administrative agent. The credit agreement consisted of a term loan of $100.0 million.

The interest rates per annum applicable to amounts outstanding under the term loan were, at the Company’s option, either (a) the alternate base rate (as defined in the credit agreement) plus 0.75%, or (b) the adjusted Eurodollar rate (as defined in the credit agreement) plus 1.75% per annum. As of December 31, 2015, the interest rate, based upon the adjusted Eurodollar rate, was 2.17%. Interest payments under the credit agreement were due on the interest payment dates specified in the credit agreement.

The credit agreement required amortization of the term loan in the form of scheduled principal payments on June 15, September 15 and December 15 of 2015, with the remaining outstanding balance due on February 15, 2016. This principal balance and outstanding interest was paid in full on February 12, 2016.

October 2013 Term Loan

On October 28, 2013, the Company entered into a credit agreement among the Company, the lenders party thereto and the Royal Bank of Canada, as administrative agent. The October 2013 Term Loan amount was for $75.0 million, with a term of one-year.

The interest rates per annum applicable to amounts outstanding under the October 2013 Term Loan were, at the Company’s option, either (a) the base rate plus 1.00%, or (b) the Eurodollar rate plus 2.00% per annum. As of the final payment date, the interest rate was 2.22%. This principal balance and outstanding interest was paid in full on October 28, 2014.

As of December 31, 2016 and 2015, the Company was in compliance with all applicable debt covenants.

As of December 31, 2016, the future minimum principal payments under the February 2018 Notes and December 2021 Notes were:
