Our leases have remaining lease terms of 1 year to 11 years. These leases generally contain renewal options for periods ranging from two to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and associated potential option payments are excluded from lease payments. Expenses associated with operating leases was $38.0 million, $38.4 million and $37.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.

A number of businesses acquired by us are located in properties owned indirectly by and leased from persons employed by the Company, none of whom are members of our senior management. In the aggregate, for the three and nine month periods ending September 30, 2019 and 2018, we made lease payments to those related parties of approximately $0.6 million and $0.8 million, respectively, and $1.8 million and $2.5 million, respectively,
