12. Restructuring Costs
We committed to a plan to reduce organizational and overhead costs in October 2008 and had subsequently modified that plan during 2011 with the goal of further reducing those costs. During the year ended December 31, 2011, we recognized $1,553 in restructuring costs, of which $1,200 related to the termination of certain office leases and $353 related to other expenses. At December 31, 2013 and 2012, $1,130 and $1,464, respectively, relating to unpaid restructuring expense was included in accounts payable, accrued expenses and other liabilities.
