Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

For the three months ended June 30, 2013 and 2014, we recognized stock-based compensation expense totaling $1.4 million and $2.2 million, respectively. A majority of the expense, $1.3 million and $1.6 million, respectively, was recorded as selling and administrative expenses in the Consolidated Statements of Operations, with the remaining expenses recorded as cost of sales and research and development. Stock-based compensation expense in the three months ended June 30, 2013 was positively impacted by a $1.3 million adjustment to compensation expense due to changes in share multiples for certain performance share units.

For the six months ended June 30, 2013 and 2014, we recognized stock-based compensation expense of $3.7 million and $2.8 million, respectively. A majority of the expense, $3.4 million and $2.1 million, respectively, was recorded as selling and administrative expenses in the Consolidated Statements of Operations, with the remaining expenses recorded as cost of sales and research and development.

As of June 30, 2014, the total compensation cost related to non-vested restricted stock, performance shares and stock options not yet recognized was $10.9 million, which will be recognized over the remaining weighted average life of 1.5 years.
