15. Subsequent events:

On August 6, 2014, the Company announced its decision to strategically scale back the Grid business significantly to support existing commitments only, unless the Company is able to find a buyer for the business in the very near-term. In conjunction with this action, the Company expects to incur significant severance and other related restructuring costs, which are expected to include cash costs as well as charges or credits related to stock-based compensation expense, and may include facilities, lease termination, asset impairment and other charges. The Company expects to recognize these charges in the quarter ending September 30, 2014.
