Royalty expense was $50.5 million, $46.4 million, and $40.0 million for the years ended December 30, 2018, December 31, 2017 and January 1, 2017, respectively. The Company is also generally required to contribute 4% of restaurant sales from the Company's restaurants to an advertising fund utilized by BKC for its advertising, promotional programs and public relations activities, and amounts for additional local advertising in markets that approve such advertising. Advertising expense associated with these expenditures was $47.0 million, $43.5 million and $40.2 million for the years ended December 30, 2018, December 31, 2017 and January 1, 2017, respectively. As of December 30, 2018, December 31, 2017, and January 1, 2017, the Company leased 244, 251 and 275 of its restaurant locations from BKC, respectively. As of December 30, 2018, for 117 of the restaurants, the terms and conditions of the lease with BKC are identical to those between BKC and their third-party lessor. Aggregate rent under these BKC leases for the years ended December 30, 2018, December 31, 2017 and January 1, 2017 was $27.2 million, $27.6 million, and $27.8 million, respectively.

The Company has entered into an Area Development and Remodeling Agreement with BKC which will be subject to the closing of the transactions contemplated by the Merger Agreement and will supersede the amended operating agreement.
