 The current portion of restructuring liabilities was $10.4 million and $6.0 million as of December 31, 2013 and December 31, 2014, respectively, which are included in Accounts payable and accrued expenses. The long-term portion is included in Other long-term liabilities.
 
(2)
 Adjustments for lease and related costs during the year ended December 31, 2014 primarily result from changes in the timing and expected income from settlements and executed sublease agreements signed during the period, which amounted to $4.1 million, partly offset by the accretion of interest on lease costs of approximately $1.3 million. Adjustments for severance and other employee separation costs primarily related to employees who were re-hired to other roles within the Company and were not paid severance.
