The following table contains pertinent information regarding these outstanding awards as of December 31, 2014 (in thousands except for number of awards granted):

Through June 30, 2012, cumulative compensation expense of $264,000 associated with the 13,000 unvested RSUs and RSAs granted in 2010 and 2011 had been recognized. From the date of grant through June 30, 2012, the Company had believed it was probable that the associated performance requirements would be achieved and therefore recognized expense on these awards. During the third quarter of 2012, the Company believed that the performance condition was no longer probable of achievement, however the Company had also not yet determined that the performance condition was improbable of achievement. Accordingly, expense recognition was discontinued beginning in the third quarter of 2012. As of December 31, 2013, the Company determined that the performance condition was improbable of achievement and therefore the cumulative compensation expense of $264,000 associated with these awards was reversed in the quarter ended December 31, 2013. No further compensation expense associated with these awards has been recorded. These awards expired unvested in April 2015.

In addition to the awards issued in 2010 and 2011, there were 95,330 non-vested RSAs as of December 31, 2014 with a grant date fair value of $2.3 million that were granted on June 10, 2014, which were also subject to service-based vesting conditions as well as certain performance-based vesting requirements that must be achieved before vesting can occur. These awards vested over a nine month period ending March 14, 2015, provided the performance conditions were met as of December 31, 2014. Of these RSAs issued in June 2014, 30,200 awards with a total fair value of approximately $743,000 were granted to employees of the Grid business. As of September 30, 2014, in conjunction with the sale of the Grid business, the Company reversed all compensation expense previously recognized associated with these awards as they will not vest. Additionally, as of December 31, 2014, 8,050 awards with a grant date fair value of approximately $198,000 were granted to employees who terminated their employment during 2014. Accordingly, the Company reversed all compensation expense previously recognized associated with these awards as they will not vest. As of December 31, 2014, the Company determined that the performance conditions associated with a portion of the remaining unvested awards with a grant date fair value of $965,000 would not be achieved and therefore any previously recorded expense associated with these awards was reversed and no additional expense was recorded during the year ended December 31, 2014.
