Restricted Stock We have granted restricted stock units (“RSUs”) as part of our long-term incentive compensation to employees and non-employee members of the Board of Directors. RSUs generally vest over a period of 3 to 5 years for employees and one year for members of the Board of Directors. The restricted common stock underlying RSUs are not deemed issued or outstanding upon grant, and do not carry any voting rights. The restricted share activity for the three months ended December 31, 2021 is summarized as follows:

As of December 31, 2021, there was $4.3 million of total unrecognized compensation cost related to unvested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.8 years. Compensation cost for share-based awards is recognized on a straight-line basis over the vesting period. Share-based compensation expense for the three months ended December 31, 2021 and 2020 was $0.7 million and $0.9 million, respectively. We repurchased 2,275 shares of our common stock for $0.1 million to cover the income tax obligation on vested employee equity awards during the three months ended December 31, 2021.
