Stock-Based Compensation

Our Board of Directors granted 157,000 stock options, 280 deferred stock units and 181,905 restricted stock units during the three months ended March 31, 2019 under our Omnibus Equity Incentive Plan.

Stock-based compensation expense was $0.3 million in the three months ended March 31, 2019, of which $0.2 million was recorded as "Selling and Administrative Expenses" in the Condensed Consolidated Statement of Operations. The remaining remainder was recorded in "Cost of Sales" and "Research and Development." There was no stock-based compensation expense recognized in the three months ended March 31, 2018.

As of March 31, 2019, unrecognized compensation cost related to non-vested stock options, deferred stock units and restricted stock units represents $8.3 million, which will be recognized over the remaining weighted average life of 4.4 years.
