Convertible Notes due 2019

In June 2014, the Company issued $200.0 million aggregate principal amount of 3.625 percent convertible senior notes due 2019 (the “convertible notes”). The Company received net proceeds of $192.9 million from the sale of the convertible notes, after deducting fees of $6.0 million and expenses of $1.1 million. At the same time, the Company used $43.2 million of the net proceeds from the sale of the convertible notes to pay the cost of convertible bond hedges, as described below, which cost was partially offset by $27.6 million in proceeds to the Company from the sale of warrants in the warrant transactions also described below.

The convertible notes are governed by the terms of an indenture between the Company, as issuer, and Wells Fargo Bank, National Association, as trustee. The convertible notes are senior unsecured obligations and bear interest at a rate of 3.625 percent per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2014. The convertible notes will mature on June 15, 2019, unless earlier repurchased or converted. The convertible notes are convertible, subject to adjustment as described below, into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election, at an initial conversion rate of approximately 107.5095 shares of common stock per $1,000 principal amount of the convertible notes, which corresponds to an initial conversion price of approximately $9.30 per share of the Company’s common stock and represents a conversion premium of approximately 32.5 percent based on the last reported sale price of the Company’s common stock of $7.02 on June 11, 2014, the date the notes offering was priced. The principal amount of the notes exceeded the if-converted value as of June 30, 2016.

The conversion rate is subject to adjustment from time to time upon the occurrence of certain events, but will not be adjusted for any accrued and unpaid interest. At any time prior to the close of business on the business day immediately preceding December 15, 2018, holders may convert their convertible notes at their option only under the following circumstances:

•

during any calendar quarter commencing after the calendar quarter ending on December 31, 2014 (and only during such calendar 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 the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 percent of the conversion price, or approximately $12.00 per share, on each applicable trading day;


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


•	upon the occurrence of specified corporate events.

On or after December 15, 2018 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 convertible notes, in multiples of $1,000 principal amount, at their option regardless of the foregoing circumstances. Upon conversion, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock, or a combination thereof, at its election.

If a make-whole fundamental change, as described in the indenture, occurs and a holder elects to convert its convertible notes in connection with such make-whole fundamental change, such holder may be entitled to an increase in the conversion rate as described in the indenture.

The Company may not redeem the convertible notes prior to the maturity date and no “sinking fund” is provided for the convertible notes, which means that the Company is not required to periodically redeem or retire the convertible notes. Upon the occurrence of certain fundamental changes involving the Company, holders of the convertible notes may require the Company to repurchase for cash all or part of their convertible notes at a repurchase price equal to 100 percent of the principal amount of the convertible notes to be repurchased, plus accrued and unpaid interest.

The indenture does not contain any financial or maintenance covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company or any of its subsidiaries. The indenture contains customary terms and covenants and events of default. If an event of default

(other than certain events of bankruptcy, insolvency or reorganization involving the Company or any of its significant subsidiaries) occurs and is continuing, the trustee by notice to the Company, or the holders of at least 25 percent in principal amount of the outstanding convertible notes by written notice to the Company and the trustee, may declare 100 percent of the principal and accrued and unpaid interest, if any, on all of the convertible notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company or any of its significant subsidiaries, 100 percent of the principal of and accrued and unpaid interest, if any, on all of the convertible notes will become due and payable automatically. Notwithstanding the foregoing, the indenture provides that, to the extent the Company elects and for up to 180 days, the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants in the indenture consists exclusively of the right to receive additional interest on the convertible notes.

In accordance with accounting guidance for debt with conversion and other options, the Company separately accounted for the liability and equity components of the convertible notes by allocating the proceeds between the liability component and the embedded conversion option, or equity component, due to the Company’s ability to settle the convertible notes in cash, common stock or a combination of cash and common stock, at the Company’s option. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The allocation was performed in a manner that reflected the Company’s non-convertible debt borrowing rate for similar debt. The equity component of the convertible notes was recognized as a debt discount and represents the difference between the proceeds from the issuance of the convertible notes and the fair value of the liability of the convertible notes on their date of issuance. The excess of the principal amount of the liability component over its carrying amount, or debt discount, is amortized to interest expense using the effective interest method over the five year life of the convertible notes. The approximate remaining discount amortization period as of June 30, 2016 was 35.5 months. The equity component will not be remeasured for changes in fair value as long as it continues to meet the conditions for equity classification.

The outstanding convertible note balances as of June 30, 2016 and December 31, 2015 consisted of the following:



In thousands	2016			2015
Liability component:
Principal	$	200,000		$	200,000
Less: debt discount and unamortized debt issuance costs	(31,116		)	(35,562		)
Net carrying amount	$	168,884		$	164,438
Equity component	$	40,896		$	40,896

In connection with the issuance of the convertible notes, the Company incurred approximately $1.1 million of debt issuance costs, which primarily consisted of legal, accounting and other professional fees, and allocated these costs to the liability and equity components based on the allocation of the proceeds. Of the total $1.1 million of debt issuance costs, $0.3 million was allocated to the equity component and recorded as a reduction to additional paid-in capital and $0.8 million was allocated to the liability component and recorded in other assets on the balance sheet. The portion allocated to the liability component is amortized to interest expense over the expected life of the convertible notes using the effective interest method.

The Company determined the expected life of the debt was equal to the five-year term on the convertible notes. The effective interest rate on the liability component was 9.625 percent for the period from the date of issuance through June 30, 2016. The following table sets forth total interest expense recognized related to the convertible notes for the three and six-month periods ended June 30, 2016 and June 30, 2015:

Convertible Bond Hedge and Warrant Transactions

In connection with the pricing of the convertible notes and in order to reduce the potential dilution to the Company’s common stock and/or offset any cash payments in excess of the principal amount due upon conversion of the convertible notes, in June 2014, the Company entered into convertible note hedge transactions covering approximately 21.5 million shares of the Company’s common stock underlying the $200.0 million aggregate principal amount of the convertible notes with JPMorgan Chase Bank, National Association, an affiliate of JPMorgan Securities LLC (the “Counter Party”). The convertible bond hedges have an exercise price of approximately $9.30 per share, subject to adjustment upon certain events, and are exercisable when and if the convertible notes are converted. Upon conversion of the convertible notes, if the price of the Company’s common stock is above the exercise price of the convertible bond hedges, the Counter Party will deliver shares of the Company’s common stock and/or cash with an aggregate value approximately equal to the difference between the price of the Company’s common stock at the conversion date and the exercise price, multiplied by the number of shares of the Company’s common stock related to the convertible bond hedges being exercised. The convertible bond hedges are separate transactions entered into by the Company and are not part of the terms of the convertible notes or the warrants, discussed below. Holders of the convertible notes will not have any rights with respect to the convertible bond hedges. The Company paid $43.2 million for these convertible bond hedges and recorded this amount as a reduction to additional paid-in capital.

At the same time, the Company also entered into separate warrant transactions with the Counter Party relating to, in the aggregate, approximately 21.5 million shares of the Company’s common stock underlying the $200.0 million aggregate principal amount of the convertible notes. The initial exercise price of the warrants is $12.00 per share, subject to adjustment upon certain events, which is approximately 70 percent above the last reported sale price of the Company’s common stock of $7.02 per share on June 11, 2014. Upon exercise, the Company will deliver shares of the Company’s common stock and /or cash with an aggregate value equal to the excess of the price of the Company’s common stock on the exercise date and the exercise price, multiplied by the number of shares, of the Company’s common stock underlying the exercise. The warrants will be exercisable and will expire in equal installments for a period of 100 trading days beginning on September 15, 2019. The warrants were issued to the Counter Party pursuant to the exemption from registration set forth in Section 4(a)(2) of the Securities Act. The Company received $27.6 million for these warrants and recorded this amount as an increase to additional paid-in capital.

Aside from the initial payment of a $43.2 million premium to the Counter Party under the convertible bond hedges, which cost is partially offset by the receipt of a $27.6 million premium under the warrants, the Company is not required to make any cash payments to the Counter Party under the convertible bond hedges and will not receive any proceeds if the warrants are exercised.

Royalty Financing

In July 2015, the Company entered into a Revenue Interest Assignment Agreement (the "RIAA") with PDL BioPharma, Inc. (“PDL”) under which the Company received an initial payment of $50 million in exchange for a percentage of global net revenues from sales of Iclusig until PDL receives a fixed internal rate of return on the funds it advances the Company. Under the original terms of the RIAA, the Company would receive an additional $50 million one year from the effective date of the agreement (July 2016) and had the option to receive up to an additional $100 million in one or two tranches between the six-month and twelve-month anniversary dates of the agreement. The proceeds received from PDL are referred to as “advances”.

Effective on June 1, 2016, in connection with the transactions with Incyte, ARIAD and PDL agreed to amend the RIAA to, among other things, include in the Iclusig net sales calculation under the RIAA net sales of Iclusig made by Incyte in the Territory under the License Agreement. In addition, ARIAD’s option to receive additional funding was restructured so that, in addition to the $50 million received in July 2016, ARIAD may require PDL to fund up to an additional $40 million (instead of the original $100 million) in July 2017 (instead of between January and July 2016).

Under the amended agreement, the Company agreed to pay PDL a percentage of global Iclusig net product revenues subject to an annual maximum payment of $20 million per year through 2018. The rate is 2.5 percent during the first year and increases to 5 percent in the second year through the end of 2018 and 6.5 percent from 2019 until PDL receives a 10 percent internal rate of return. Through June 30, 2016, the Company has paid a total of $3.9 million to PDL under this agreement. Payments are deemed to be applied against advances. Interest expense related to the agreement was $1.3 million and $2.3 million, respectively, for the three- and six-month periods ended June 30, 2016.

Beginning in 2019, if PDL does not receive specified minimum payments each year from sales of Iclusig, then it will also have the right to receive a certain percentage of net revenues from sales of brigatinib, subject to its approval by regulatory authorities. If PDL has not received total cumulative payments under this agreement that are at least equal to the amounts PDL has advanced to the Company by the fifth anniversary of each funding date, the Company is required to pay PDL an amount equal to the shortfall.

PDL retains the option to require the Company to repurchase the then outstanding net advances, together with additional payments representing return on investment as described below (the “put” option), in the event the Company experiences a change of control, undergoes certain bankruptcy events, transfers any of its interests in Iclusig (other than pursuant to a license agreement, development, commercialization, co-promotion, collaboration, partnering or similar agreement), transfers all or substantially all of its assets, or breaches certain of the covenants, representations or warranties made under the agreement. Similarly, the Company has the option to terminate the agreement at any time by payment of the then outstanding net advances, together with additional payments representing return on investment as described below (the “call” option). Both the put and call options can be exercised at a price which is equal to the greater of (a) the then outstanding net advances and an amount that would generate an internal rate of return to PDL of 10 percent after taking into account the amount and timing of all payments made to PDL by the Company or (b) a multiple of the then outstanding net advances of 1.15 if exercised on or prior to the first anniversary of the closing date, 1.20 if exercised after the first anniversary but on or prior to the second anniversary of the closing date or 1.30 if exercised after the second anniversary of the closing date.

In connection with the agreement, the Company also entered into a security agreement with PDL in July 2015, as amended effective June 1, 2016. Under the security agreement, the Company granted PDL a security interest in certain assets relating to Iclusig, including all of the Company’s revenues from sales of Iclusig covered by the royalty financing agreement, a certain segregated deposit account established under the royalty financing agreement, and certain intellectual property, license agreements, and regulatory approvals related to Iclusig. The collateral set forth in the security agreement secures the Company’s obligations under the royalty financing agreement, including its obligation to pay all amounts due thereunder. In connection with the amendment to the RIAA, ARIAD and PDL agreed to release ARIAD’s European patents and certain other European assets from the collateral.

For accounting purposes, the agreement has been classified as a debt financing, as the Company will have significant continuing involvement in the sale of Iclusig and other products which might be covered by the agreement, the parties have the right to cancel the agreement as described above, PDL’s rate of return is implicitly limited by the terms of the transaction, volatility in the sale of Iclusig and other products would have no effect on PDL’s expected ultimate return, and PDL has certain rights in the event that product sales and related payments under this agreement are insufficient to pay down the Company’s obligations.

In connection with the transaction, the Company recorded the initial net proceeds as long-term debt. The Company imputes interest expense associated with this borrowing using the effective interest rate method and will record a corresponding accrued interest liability. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement, including the required 10 percent internal rate of return to PDL. Determining the effective interest rate requires judgment and is based on significant assumptions related to estimates of the amounts and timing of future revenue streams. Determination of these assumptions is highly subjective and different assumptions could lead to significantly different outcomes.

The Company determined that the put option is an embedded derivative. This item is being accounted for as a derivative and the estimated fair value of the put option, which was immaterial as of the date of the agreement and as of June 30, 2016 is carried as part of the carrying value of the related liability.

Facility Lease Obligation

As of June 30, 2016 and December 31, 2015, the Company has recorded a facility lease obligation related to its lease for a new facility under construction in Cambridge, Massachusetts. See Notes 6 and 10 for information regarding the lease and related asset under construction. During the construction period the Company is capitalizing the construction costs as a component of construction in progress with a corresponding credit to facility lease obligation to the extent the cost was paid by the Company or reimbursed by the landlord.

The Company expects to complete construction and occupy the facility in the fourth quarter of 2016. Under terms of the lease, the Company commenced making lease payments in March 2015. During the construction period, a portion of the lease payment is allocated to land lease expense and the remainder is accounted for as a reduction of the obligation. See Note 10 for information regarding payments and other terms.
