NOTE l—STOCKHOLDERS’ EQUITY

During the first three months of 2016, the Company repurchased 275,460 shares of common stock at an average purchase price of $8.74 per share for an aggregate purchase price of $2,407. As of March 31, 2016, 629,580 shares of common stock remained authorized for repurchase under the Company's board-authorized share repurchase program.

Repurchases of common stock are accounted for as treasury stock, and result in a reduction of stockholders’ equity. When treasury shares are reissued, the Company accounts for the reissuance in accordance with Accounting Principles Board Opinion No. 6, "Status of Accounting Research Bulletins" and charges the excess of the repurchase cost over issuance price using the weighted average method to accumulated deficit. In the case where the repurchase cost over issuance price using the weighted average method is lower than the issuance price, the Company credits the difference to additional paid-in capital.

During the first three months of 2016, the Company issued approximately 399,000 shares of common stock out of treasury stock to employees who exercised their stock options, SARs or RSUs, or purchased shares from the Company’s 1993 Employee Stock Purchase Plan.
