The Company has prior incentive plans under which previously granted awards remain outstanding, including the 2017 Plan, but under which no new awards may be granted. At January 31, 2024, the Company had reserved a total of 245,150 shares for grants and issuances under these incentive stock plans, which includes a reserve for issuances pursuant to unvested or unexercised prior awards. While the 2017 Plan provided for the grant of deferred shares, non-qualified stock options, incentive stock options, restricted shares, restricted stock units, and performance-based restricted stock units intended to qualify under section 422 of the Internal Revenue Code, the Company issued only restricted shares and restricted stock units under the 2017 Plan. The 2017 Plan authorized awards to officers, employees, consultants, and independent directors. The Company's 2021 Omnibus Stock Incentive Plan dated May 26, 2021 was approved by the Company's stockholders in May 2021 ("2021 Plan"). The 2021 Plan will expire in May 2024. The 2021 Plan authorizes awards to officers, employees, consultants and independent directors. Grants were made to the Company's employees, officers and independent directors under the 2021 Plan, as described below.

There was no vesting, expiration or forfeiture of previously unvested stock options during the year ended January 31, 2024. In addition, there were no remaining unvested stock options outstanding, and therefore no unrecognized compensation expense related to unvested stock options during the year ended January 31, 2024. Deferred stock As part of their compensation, in previous years the Company granted deferred stock units to each non-employee director, equal to the result of dividing the award amount by the fair market value of the common stock on the date of grant. The stock vests on the date of grant; however, it is distributed to the directors only upon their separation from service. During the year ended January 31, 2024, no deferred stock units were distributed. There were approximately 62,926deferred stock units outstanding included in the restricted stock activity shown below as of January 31, 2024 and 2023, respectively. Restricted stock The Company has granted restricted stock to executive officers, independent directors, and employees. The restricted stock vests ratably over one to four years. 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 years ended January 31, 2024 and 2023, respectively:
|  | Restricted shares |  |  | Weighted average price |  |  | Weighted average grant date fair value |
Outstanding on January 31, 2022 |  |  | 353 |  |  | $ | 7.48 |  |  | $ | 2,652 |
Granted |  |  | 102 |  |  |  | 10.96 |  |  |  |  |

Forfeited |  |  | (42 | ) |  |  | 6.87 |  |  |  |  |
Outstanding on January 31, 2023 |  |  | 266 |  |  | $ | 8.55 |  |  | $ | 2,286 |
Granted |  |  | 92 |  |  |  | 10.26 |  |  |  |  |

Outstanding on January 31, 2024 |  |  | 222 |  |  | $ | 9.33 |  |  | $ | 2,078 |
The fair value of vested restricted stock was $1.1 million and $1.2 million in the year ended January 31, 2024 and 2023 respectively. Additionally, t here was $1.0 million and $1.1 million of unrecognized compensation cost related to unvested restricted stock granted under the plans as of January 31, 2024 and 2023, respectively.
