Shareholders' Equity and Share-Based Compensation

Share Repurchase Program and Treasury Shares

On September 30, 2015, the Board authorized a share repurchase program allowing repurchases of up to $50.0 million of HMEC's common stock, par value $0.001 (Program). The Program authorizes the repurchase of common shares in open market or privately negotiated transactions, from time to time, depending on market conditions. The Program does not have an expiration date and may be limited or terminated at any time without notice.

During 2021, the Company repurchased 140,758 shares of its common stock, or 0.3% of the shares outstanding as of December 31, 2020, at an aggregate cost of $5.3 million, or an average price of $37.49 per share. During 2020, the Company repurchased 52,095 shares of its common stock, or 0.1% of the shares outstanding as of December 31, 2019, at an aggregate cost of $2.2 million, or an average price of $41.17 per share. During 2019, the Company did not repurchase any shares of its common stock. In total and through December 31, 2021, 1,040,226 shares were repurchased under the Program at an average price of $33.33 per share. The repurchase of shares was funded through use of cash. As of December 31, 2021, $15.3 million remained authorized for future share repurchases under the Program.

At December 31, 2021, the Company held 25,043,337 shares in treasury.

Authorization of Preferred Stock

In 1996, the shareholders of HMEC approved authorization of 1,000,000 shares of 0.001 par value preferred stock. The Board is authorized to (1) direct the issuance of the preferred stock in one or more series, (2) fix the dividend rate, conversion or exchange rights, redemption price and liquidation preference, of any series of the preferred stock, (3) fix the number of shares for any series and (4) increase or decrease the number of shares of any series. No shares of preferred stock were issued or outstanding at December 31, 2021 and 2020.

2010 Comprehensive Executive Compensation Plan

In 2010, the shareholders of HMEC approved the 2010 Comprehensive Executive Compensation Plan (the Comprehensive Plan). The purpose of the Comprehensive Plan is to aid the Company in attracting, retaining, motivating and rewarding employees and non-employee Directors; to provide for equitable and competitive compensation opportunities, including deferral opportunities; to encourage long-term service; to recognize individual contributions and reward achievement of Company goals; and to promote the creation of long-term value for the Company's shareholders by closely aligning the interests of plan participants with those of shareholders. The Comprehensive Plan authorizes share-based and cash-based incentives for plan participants. In 2012, the shareholders of HMEC approved the implementation of a fungible share pool under which grants of full value shares will count against the share limit as two and one half shares for every share subject to a full value award. In May 2021, the shareholders of HMEC approved an amendment and restatement of the Comprehensive Plan which included an increase of 2,500,000 in the number of shares of common stock reserved for issuance under the Comprehensive Plan. As of December 31, 2021, approximately 2,688,416

shares were available for grant under the Comprehensive Plan. Shares of common stock issued under the Comprehensive Plan may be either authorized and unissued shares of HMEC or shares that have been reacquired by HMEC; however, new shares have been issued historically.
