Restructuring And Related Activities [Abstract] |
Restructuring Charges | 8. Restructuring Charges On December 19, 2016, the Board of Directors approved a restructuring of its business based on its decision to focus the Company’s efforts on clinical development, with an initial focus on the X358 clinical programs In early 2017, the Company further revised its strategy to prioritize out-licensing activities and further curtail research and development spending. The restructuring included a reduction in force in which the Company terminated a total of 62 employees. Charges related to these initiatives were complete by the end of fiscal year 2017. Prior to 2017, the Company’s operations were located in two buildings in Berkeley, California. Due to the restructuring activity and reduction in headcount, the Company determined that it did not need the building space in Berkeley, California and consolidated all of its personnel in a new office facility in Emeryville, California. During the year ended December 31, 2018, the Company completely vacated both of its leased facilities in Berkeley, California and subleased the space to subtenants. In connection with vacating this space, the Company recorded a discounted lease-related restructuring liability, which was calculated as the present value of the estimated future facility costs for which the Company would obtain no future economic benefit over the term of the lease, net of estimated future sublease income, and adjusted for the remaining balance of deferred rent. In addition, in connection with the sublease agreement executed in April 2018, the Company recognized a loss on the sublease of $0.6 million, which was recorded in the restructuring charges line item of the condensed consolidated statement of operations and comprehensive loss during the three months ended June 30, 2018 (see Note 11). As of December 31, 2018, the Company classified the current portion of the combined lease-related liabilities of $1.4 million within accrued and other liabilities and the non-current portion of $0.3 million within other liabilities non-current in its consolidated balance sheet. Upon adoption of ASC 842, the Company consolidated all its lease-related liabilities in the condensed consolidated balance sheet as of January 1, 2019 and reported as operating lease liabilities (see Note 2). During the three months ended March 31, 2019 and 2018, no lease-related restructuring charges were recognized in the condensed consolidated statements of operations and comprehensive income (loss).
