8. Commitments and Contingencies

Operating Lease and Lease Guarantee

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. As of December 31, 2014, the total lease payments for the duration of the lease, which runs through May 2020, were $33.4 million. We would be responsible for lease-related payments including utilities, property taxes, and common area maintenance, which may be as much as the actual lease payments. 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. We prepared a discounted, probability-weighted cash flow analysis to calculate the estimated fair value of the lease guarantee as of the Spin-Off. We were required to make assumptions regarding the probability of Theravance Biopharma's default on the lease payments, the likelihood of a sublease being executed, and the times at which these events could occur. The fair value of this lease guarantee was charged to additional paid in capital upon the Spin-Off, and any future adjustments to the carrying value of the obligation will be recorded in the consolidated statements of operations.

Following the Spin-Off, we entered into a Sublease Agreement with Theravance Biopharma to sublease 4,847 square feet of office space in South San Francisco, California, which expires in May 2020. We do not own or lease any other properties. Future minimum lease payments under this lease at December 31, 2014, were as follows:

Special Long-Term Retention and Incentive Cash Awards Program

In 2011, we granted special long-term retention and incentive cash bonus awards to certain employees. The awards have dual triggers of vesting based upon the achievement of certain performance conditions over a six-year timeframe from 2011 through December 31, 2016 and continued employment.

As of March 31, 2014, we determined that the achievement of the requisite performance conditions for the first tranche of these awards was probable and, as a result, $9.1 million of cash bonus expense was recognized in the first quarter of 2014, the majority of which is included in discontinued operations in the consolidated statements of operations. In May 2014, the total cash bonus of $9.5 million for the first tranche was paid.

In connection with the Spin-Off, the Compensation Committee approved the modification of the remaining tranches related to these awards as the performance conditions associated with the remaining portions of these awards were unlikely to be consistent with the new strategies of each company following the separation. The modification acknowledged the Spin-Off and permitted recognition of achievement of certain of the original performance conditions that were met prior to the Spin-Off, triggering service-based vesting for a portion of the cash awards. The amount payable by us under these modified cash bonus awards is $0.5 million. The remaining tranches of the cash awards were forfeited.

Guarantees and Indemnifications

We indemnify our officers and directors for certain events or occurrences, subject to certain limits. We believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recognized any liabilities relating to these agreements as of December 31, 2014.
