Q2 2015 Restructuring Plan

During the three months ended June 30, 2015, our board of directors authorized, and we implemented a restructuring plan that included a reduction in work force as part of the overall plan to reduce the Company’s long term cost structure. As a result of ongoing initiatives associated with this restructuring, we recorded a charge of $0.9 million in the nine months ended September 30, 2016, which is included in operating expenses in our consolidated statement of operations and comprised of lease and contract termination costs. The remaining liability related to our Q2 2015 restructuring plan as of September 30, 2016 was $20.8 million and is expected to be paid out over the next 5.8 years.
