9.   Employee Benefits and Compensation Plans

In January 2013, NCLH adopted the 2013 Performance Incentive Plan, which provided for the issuance of up to 15,035,106 of NCLH’s ordinary shares pursuant to awards granted under the plan. In May 2016, May 2021 and June 2022, the plan was amended and restated (the “Restated 2013 Plan”) pursuant to approval from the Board of Directors and NCLH’s shareholders. Among other things, under the Restated 2013 Plan, the number of NCLH’s ordinary shares that could have been delivered pursuant to all awards granted under the plan was increased to a maximum aggregate limit of 39,375,106 shares. In June 2023, NCLH’s shareholders approved a further amendment and restatement of the Restated 2013 Plan to increase the number of NCLH ordinary shares that may be delivered by 2,633,900, resulting in an increase in the maximum aggregate limit to 42,009,006 shares.
