10. Spin-Off of Theravance Biopharma, Inc.

On June 1, 2014, we separated our late-stage partnered respiratory assets from our biopharmaceutical research and drug development operations. We contributed the assets and certain liabilities from the research and drug development operations and $393.0 million of cash, cash equivalents and marketable securities to Theravance Biopharma. All outstanding shares of Theravance Biopharma were then distributed to our stockholders of record on May 15, 2014 as a pro-rata dividend distribution of one ordinary share of Theravance Biopharma for every 3.5 shares held of our common stock.

On June 1, 2014, we entered into a Separation and Distribution Agreement with Theravance Biopharma that set forth the terms and conditions of the separation of Theravance Biopharma from us. The Separation and Distribution Agreement sets forth a framework for the relationship between us and Theravance Biopharma following the separation regarding principal transactions necessary to separate Theravance Biopharma from us. This agreement also sets forth other provisions that govern certain aspects of our relationship with Theravance Biopharma after the completion of the separation from us and provides for the allocation of assets, liabilities and obligations between Theravance Biopharma and us in connection with the Spin-Off.

In addition, we entered into other definitive agreements in connection with the Spin-Off, including (1) a Transition Services Agreement pursuant to which Theravance Biopharma and we will provide each other with a variety of administrative services, including financial, tax, accounting, information technology, legal and human resources services, for a period of time of up to 12 months following the Spin-Off, (2) a Tax Matters Agreement that generally governs the parties' respective rights, responsibilities and obligations after the separation with respect to taxes, (3) a Sublease Agreement that provides for the sublease from Theravance Biopharma to us for certain office space to be utilized in our operations and (4) an Employee Matters Agreement that allocates liabilities and responsibilities relating to employee compensation, benefit plans, programs and other related matters in connection with the separation, including the treatment of outstanding incentive awards and certain retirement and welfare benefit obligations. These arrangements contain the provisions related to the Spin-Off and the distribution of Theravance Biopharma's ordinary shares to our stockholders.

The total amount of the Theravance Biopharma share dividend of $402.9 million was based on the net book value of the net assets that were contributed to Theravance Biopharma in connection with the Spin-Off, as follows:

Due to the Spin-Off, the leases for the facilities in South San Francisco, California, which formerly served as our headquarters, were assigned to Theravance Biopharma. We would be held liable by the landlord if Theravance Biopharma defaults under its lease obligations, and thus, we have in substance guaranteed the payments under the lease agreements for these facilities. We recorded a non-current liability of $1.3 million in our consolidated balance sheet as of December 31, 2014 related to the estimated fair value of this lease guarantee. See Note 8, "Commitments and Contingencies" for further information on this lease guarantee.

Theravance Biopharma's historical results of operations have been presented as discontinued operations in our consolidated statement of operations for the years ended December 31, 2014 and 2013. See Note 11, "Discontinued Operations," for further information.
