License agreement term, description	Pursuant to a license agreement (“License Agreement”) with Sesame Workshop, the Company pays a specified annual license fee, as well as a specified royalty based on revenues earned in connection with sales of licensed products, all food and beverage items utilizing the licensed elements and any events utilizing such elements if a separate fee is paid for such event. The Company’s principal commitments pursuant to the License Agreement include, among other items, the opening of a second standalone park (“Standalone Park”) (the Company opened the Standalone Park in San Diego on March 26, 2022) and minimum annual capital and marketing thresholds. After the opening of the second Standalone Park (counting the existing Sesame Place Standalone Park in Langhorne, Pennsylvania), SEA has the option to build additional Standalone Parks in the Sesame Territory within agreed upon timelines. The License Agreement has an initial term through December 31, 2031, with an automatic additional 15-year extension plus a five-year option added to the term of the License Agreement from December 31st of the year of each new Standalone Park opening. As of December 31, 2023, the Company estimates the combined remaining liabilities and obligations for the License Agreement commitments could be up to approximately $20.0 million over the remaining term of the agreement. See further discussion concerning royalty payments for the year 2021 in the Sesame Workshop Arbitration section which follows.
