(1) | The Company was listed in the plan's Form 5500 as providing more than 5% of the total contributions for the plan years 2019 and 2018 for both the Southern Nevada Culinary and Bartenders Pension Plan and UHF. At the date the financial statements were issued, Form 5500 was not available for the plan year 2020.
(2) | The zone status is based on information that the Company received from the plan and is certified by the plan's actuary. Plans in the red zone are generally less than 65% funded (critical status) and plans in the green zone are at least 80% funded.
(3) | Indicates plans for which a Financial Improvement Plan (FIP) or a Rehabilitation Plan (RP) is either pending or has been implemented.
(4) | There have been no significant changes that affect the comparability of contributions.
(5) | The Company is party to twelve collective bargaining agreements (CBA) that require contributions with the Local Joint Executive Board of Las Vegas, which is made up of the Culinary Workers Union and Bartenders Union. The agreements between Aria, Bellagio, Mandalay Bay, and MGM Grand Las Vegas are the most significant because more than half of the Company’s employee participants in this plan are covered by those four agreements.
(6) | Effective January 1, 2018, the Pension Benefit Guaranty Corporation approved the spin-off of the UNITE HERE portion of the Legacy Plan of the National Retirement Fund (NRF) to the newly formed UHF. As a result of the spin-off, the pension liabilities as well as certain assets of the plan were transferred to the new plan. The terms of the UHF plan are identical to the NRF plan.
