Restructuring

In September 2013, the Company commenced certain restructuring initiatives (“2013 Initiatives”) including the closure of the Company’s development site in Calgary, Canada, and the consolidation of certain supply chain management activities. During February and March 2014, the Company commenced additional reduction-in-force initiatives resulting in headcount reductions of 41 employees and 21 employees, respectively, and during June 2014 a further headcount reduction of five employees at its Calgary, Canada site.

In June 2014, the Company commenced certain restructuring initiatives relating to the reorganization of executive level management (“2014 Initiatives”), which included among other actions, the replacement of the former Chief Executive Officer with the current Chief Executive Officer. All amounts that remained due in connection with the 2014 Initiatives were paid in full during the three months ended March 31, 2015.

During the six months ended June 30, 2015, the Company recorded reductions in restructuring related charges of approximately $0.2 million resulting from a reevaluation of its expected remaining restructuring accrual for severance and facility exit related costs at June 30, 2015.

The Company accounts for facility exit costs in accordance with FASB ASC Topic 420, Exit or Disposal Cost Obligations, which requires that a liability for such costs be recognized and measured initially at fair value on the cease-use date based on remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized, reduced by the estimated sublease rentals that could be reasonably obtained even if the Company does not intend to sublease the facilities.

The Company is required to estimate future sublease income and future net operating expenses of the facilities, among other expenses. The most significant of these estimates relate to the timing and extent of future sublease income which reduce lease obligations, and the probability that such sublease income will be realized. The Company based estimates of sublease income, in part, on information from third party real estate experts, current market conditions and rental rates, an assessment of the time period over which reasonable estimates could be made, and the location of the respective facility, among other factors. Further adjustments to the facility exit liability accrual will be required in future periods if actual exit costs or sublease income differ from current estimates. Exit costs recorded by the Company under these provisions are neither associated with, nor do they benefit, continuing activities.

The following table sets forth activity in the restructuring liability for the six months ended June 30, 2015 (in thousands):
