As of October 31, 2014, there was $0.9 million of total unrecognized compensation expense related to unvested stock options. The expense is expected to be recognized over a period of 2.6 years. Restricted stock In June 2014 under the Company's 2013 Omnibus Plan, the Company granted deferred stock units to each non-employee director at the time of the annual meeting of stockholders equal to the result of dividing $30,000 by the fair market value of the common stock on the date of grant. The stock will be distributed to the directors upon their separation from service. During the second quarter of 2014, two board members retired and 7,580 shares of common stock were issued to them. In June 2014 under the 2013 Omnibus Plan, the Company granted restricted stock to Tier I and Tier II executive officers. A portion of the restricted stock vests in annual installments over two years, a portion vests in annual installments over three years and a portion vests in three years based on performance. Until restricted stock becomes vested and nonforfeitable, it may not be sold, assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise), except by will or the laws of descent and distribution, and is not subject to execution, attachment or similar process. The Company issues new shares from its authorized but unissued share pool. The Company calculates restricted stock compensation expense based on the grant date fair value and recognizes expense on a straight-line basis over the vesting period. The following table summarizes restricted stock activity for the year:
Restricted stock activity | Shares Outstanding | Weighted Average Exercise Price Per Share | Aggregate Intrinsic Value
Outstanding at January 31, 2014 | 29 |  |  | $14.52 |  |  | $419 |
Granted | 84 |  | 12.41 |  |
Issued | (80 | ) |  |
Outstanding end of period | 33 |  |  | $9.12 |  |  | $305 |
As of October 31, 2014, there was $0.5 million of unrecognized compensation expense related to unvested restricted stock granted under the plans. The cost is expected to be recognized over the weighted-average period of 2.0 years.
