Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation—Nonretirement Postemployment Benefits (“ASC 712”). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.

The $0.3 million charged to operations in the three months ended June 30, 2018 is related to exit costs incurred for the move of the Company's corporate office.

On April 3, 2017, the Board of Directors approved a plan to reduce the Company’s global workforce by approximately 8%, effective April 4, 2017. The purpose of the workforce reduction was to reduce operating expenses to better align with the Company’s current revenues. Included in the $1.3 million severance pay, charged to operations in the three months ended June 30, 2017, is $0.5 million of severance pay for one of the Company's former executive officers pursuant to the terms of a severance agreement dated June 30, 2017. Under the terms of the severance agreement, the Company's former executive officer is entitled to 18 months of his base salary, which is expected to be paid by December 31, 2018. From and after January 1, 2018, the Company, at its discretion, may settle any remaining unpaid cash severance owed to its former executive officer through the issuance of a number of immediately vested shares of the Company’s common stock, determined by multiplying the remaining unpaid cash severance owed by 120%, and then dividing by the closing stock price per share of the Company's common stock as of the last business day prior to the issuance of the shares.

All amounts related to these restructuring activities are expected to be paid by December 31, 2018.
