Employee-related termination costs primarily include severance benefits, under both ongoing and one-time benefit arrangements that are payable at termination dates throughout 2017, with the majority expected to be paid in the second half of 2017. Contract termination costs and fixed asset impairments were incurred in connection with the Bellevue facility's operating lease and related fixed assets, which are described further in the next two paragraphs, respectively. Stock-based compensation primarily includes the impact of equity award modifications associated with employment contracts for certain individuals impacted by the relocation, as well as forfeitures that were recorded for severed employees. Other costs include office moving costs.

The Company has a non-cancelable operating lease that runs through 2020 for its former corporate headquarters in Bellevue, Washington, which the Company occupied until May 2017. In March 2017, the Company agreed to a sublease for the entire Bellevue facility, which was effective June 1, 2017 and expires on September 30, 2020, consistent with the underlying operating lease. Under that sublease agreement, the Company will not recover all of its remaining lease rental obligations (including common area maintenance costs and real estate taxes) and, therefore, recognized a loss on sublease of $1.1 million. See "Note 9: Commitments and Contingencies" for additional information on the sublease. The Company also wrote-off its $1.5 million deferred rent liability (a non-cash item), related to various lease incentives that had been provided originally by the landlord, and incurred broker commissions related to the sublease agreement. All of these items were recorded as contract termination costs in the first quarter of 2017.

The Company began receiving sublease offers in the first quarter of 2017, at which point it was indicated that the remaining lease rental obligations, and the related value for the leasehold improvements and the office furniture and equipment, would not be fully recovered. As a result and given the nature of these fixed assets, the Company fully impaired the $1.9 million carrying value of those assets in the first quarter of 2017.
