Stock-Based Compensation

On January 17, 2019, our shareholders approved amendments to the Company’s amended and restated 2000 Stock Plan (the “Amended and Restated 2000 Stock Plan”). The Amended and Restated 2000 Stock Plan (i) increases the number of shares issuable by 82,250,000 to 83,500,000 shares; (ii) permits the Company’s Board of Directors (the “Board”) to make proportional adjustments to outstanding awards affected by a change in the Company’s capital structure, and in addition to or in lieu of such adjustments, to permit the Board to pay dividends, dividend equivalents, or similar rights in conjunction to any such changes in the Company’s capital structure; and (iii) certain updates to reflect changes in law relating to Section 162(m).

As of March 31, 2019, we had 8.4 million shares available for future grants under the Amended and Restated 2000 Stock Plan. We recognize stock-based compensation expenses over the requisite service periods. Our share-based awards are classified within equity. The amounts included in the condensed consolidated statements of operations related to stock-based compensation are as follows (dollars in thousands):
