11. SHARE-BASED COMPENSATION
Effective July 1, 2015, our eligible employees commenced participation in the 2015 LTIP. The 2015 LTIP authorizes the Board to grant stock options, stock appreciation rights, restricted shares, restricted share units, performance awards, and dividend equivalents. All grants are made by issuing new shares and no more than 4.0 million shares of common stock may be issued under the 2015 LTIP. As of June 30, 2020, we had 2.1 million shares remaining available for issuance under the 2015 LTIP.
