Convertible Subordinated Notes Due 2023

In January 2013, we completed an underwritten public offering of $287.5 million aggregate principal amount of unsecured convertible subordinated notes, which will mature on January 15, 2023 (the “2023 Notes”). The financing raised proceeds, net of debt issuance costs, of approximately $281.2 million, less $36.8 million to purchase two privately-negotiated capped call option transactions in connection with the issuance of the notes. The 2023 Notes bear interest at the rate of 2.125% per year that is payable semi-annually in arrears in cash on January 15 and July 15 of each year, beginning on July 15, 2013.

The 2023 Notes were convertible, at the option of the holder, into shares of our common stock at an initial conversion rate of 35.9903 shares per $1,000 principal amount of the 2023 Notes, subject to adjustment in certain circumstances, which represents an initial conversion price of approximately $27.79 per share. Following the Spin-Off of Theravance Biopharma, a number of adjustments to the initial conversion rate have been made as described below. Holders of the 2023 Notes will be able to require us to repurchase some or all of their notes upon the occurrence of a Change of Control or a Termination of Trading (as contractually defined) following the original issuance of the 2023 Notes at 100% of the principal amount of the notes being repurchased plus accrued and unpaid interest. We may not redeem the 2023 Notes prior to their stated maturity date.

In connection with the offering of the 2023 Notes, we entered into two privately-negotiated capped call option transactions with a single counterparty. The capped call option transaction is an integrated instrument consisting of a call option on our common stock purchased by us with a strike price equal to the initial conversion price of $27.79 per share for the underlying number of shares and a cap price of $38.00 per share, both of which are subject to adjustments consistent with the 2023 Notes. The cap component is economically equivalent to a call option sold by us for the underlying number of shares with an initial strike price of $38.00 per share. As an integrated instrument, the settlement of the capped call coincides with the due date of the convertible debt. Upon settlement, we would receive from our hedge counterparty a number of shares of our common shares that would range from zero, if the stock price was below $27.79 per share, to a maximum of 2,779,659 shares, if the stock price is above $38.00 per share. However, if the market price of our common stock, as measured under the terms of the capped call transactions, exceeds $38.00 per share, there is no incremental anti-dilutive benefit from the capped call.

In accordance with the agreement for the 2023 Notes, the conversion rate was adjusted as a result of the completion of the Spin-Off of Theravance Biopharma. The conversion rate was adjusted based on the conversion rate immediately prior to the record date for the Spin-Off and the average of the stock dividend distributed to our common stockholders and our stock prices. This resulted in an adjusted conversion rate of 46.9087 shares per $1,000 principal amount of the 2023 Notes, which represents an adjusted conversion price of approximately $21.32 per share. As a result of the conversion rate adjustment, the capped call strike price and cap price were also adjusted accordingly to $21.32 and $29.16, respectively. On July 15, 2014, certain holders of the 2023 Notes converted their notes into 1,519,402 shares of our common stock at the adjusted conversion price of $21.32 per share. In connection with the partial conversion of the 2023 Notes, we received 149,645 shares of our common stock from our capped call option counterparty and the shares of common stock received were recorded as treasury stock.

In connection with the payments of subsequent cash dividends through September 30, 2015, the adjusted conversion rate with respect to our 2023 Notes was further adjusted from 46.9087 shares of our common stock per $1,000 principal amount of the 2023 Notes to 50.5818 shares of our common stock per $1,000 principal amount of the 2023 Notes, which represents an adjusted conversion price of approximately $19.77 per share. As a result of the conversion rate adjustment, the capped call strike price and cap price were also adjusted accordingly to $19.77 and $27.04.

Non-Recourse Notes Due 2029

In April 2014, we entered into certain note purchase agreements relating to the private placement of $450.0 million aggregate principal amount of non-recourse fixed rate term notes due 2029 (the “2029 Notes”) issued by our wholly-owned subsidiary.

The 2029 Notes are secured by a security interest in a segregated bank account established to receive 40% of royalties due to us under the LABA Collaboration with GSK commencing on April 1, 2014 and ending upon the earlier of full repayment of principal or May 15, 2029. The amounts in the segregated bank account can only be used to make interest and principal payments on the 2029 Notes. As of September 30, 2015, the balance of the segregated bank account was not material.

The 2029 Notes bear an annual interest rate of 9%, with interest and principal paid quarterly beginning November 15, 2014. The 2029 Notes may be redeemed at any time prior to maturity, in whole or in part, at specified redemption premiums. Prior to May 15, 2016, in the event that the specified portion of royalties received in a quarter is less than the interest accrued for the quarter, the principal amount of the 2029 Notes will increase by the interest shortfall amount for that period. Since issuance, $39.0 million of interest expense has been added to the principal balance of the 2029 Notes, of which $5.6 million and $18.4 million was added during the three and nine months ended September 30, 2015. No interest expense was added to the principal during the three and nine months ended September 30, 2014. Since the principal and interest payments on the 2029 Notes are based on royalties from GSK for product sales recorded, which will vary from quarter to quarter and are unknown to us, the 2029 Notes may be repaid prior to the final maturity date in May 2029.

In connection with the sale of the 2029 Notes, we incurred approximately $15.3 million in debt issuance costs, which are being amortized to interest expense over the estimated life of the 2029 Notes.
