[1] Costs associated with the write-off of inventory are included in cost of materials in the condensed consolidated statements of operations and comprehensive loss. All other costs are recorded to the restructuring charges line item within the condensed consolidated statements of operations and comprehensive loss as they are incurred.

[2] Cash payments are expected to be made during the third and fourth quarters of 2013 for all the restructuring reserve activity except for the lease termination costs. Payments on certain of the lease obligations are scheduled to continue until 2016. Market conditions and the Company’s ability to sublease these properties could affect the ultimate charge related to the lease obligations. Any potential recoveries or additional charges could affect amounts reported in the Condensed Consolidated Financial Statements of future periods.
