Shares repurchased under this program were permitted either through the open market or privately negotiated transactions from time to time and in amounts that management deemed appropriate. During the first quarter of fiscal 2015, we repurchased 287,787 shares for $2.2 million under this plan which expired on October 31, 2014.

Restricted Stock Unit Withholdings We issue restricted stock units as part of our equity incentive plans. When the restricted stock units vest and become taxable to our employees, they may elect to have us deduct shares on their behalf to pay the appropriate taxing authorities. In our consolidated financial statements, we treat these shares withheld for tax purposes on behalf of our employees as common stock repurchases. These withheld shares are not considered common stock repurchases on our authorized common stock repurchase program. During fiscal 2015, we used $0.1 million to repurchase shares to satisfy these withholding obligations.
