CHENIERE ENERGY, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED The table below provides a summary of our restricted share unit and performance stock unit awards outstanding assuming payout at target for awards containing performance conditions (in millions, except for per unit information): The table below provides a summary of restricted share unit and performance stock unit awards issued: Phantom units are share-based awards granted to employees over a vesting period that entitle the grantee to receive the cash equivalent to the value of a share of our common stock upon each vesting. We did not issue any phantom units to our employees and non-employee directors during the years ended December 31, 2018 and 2017. During the year ended December 31, 2016, we issued 1.8 million phantom units to our employees and non-employee directors. Phantom units are not eligible to receive quarterly distributions. These awards vest based on service conditions (two, three or four-year service periods). The table below provides a summary of our phantom units outstanding (in millions): The value of phantom units vested during the years ended December 31, 2018, 2017 and 2016 was $91 million, $86 million and $78 million, respectively. We have a defined contribution plan (“401(k) Plan”) which allows eligible employees to contribute up to 75% of their compensation up to the IRS maximum. We match each employee’s deferrals (contributions) up to 6% of compensation and may make additional contributions at our discretion. Employees are immediately vested in the contributions made by us. Our contributions to the 401(k) Plan were $9 million, $7 million and $6 million for the years ended December 31, 2018, 2017 and 2016, respectively.
