Further, although the customer mix of real estate sales in our Land Operations segment may be diverse in any given period, during the years ended December 31, 2018 and December 31, 2019, the Land Operations segment recognized gross profits of $162.2 million and $6.7 million, respectively, in connection with the sale of approximately 41,000 acres of Maui agricultural land and 100% of the Company's ownership interest in Central Maui Feedstocks LLC and Kulolio Ranch LLC (collectively referred to as the "Agricultural Land Sale").</span>

Further, a reclassification was made to the consolidated statements of cash flows to present, on a net basis, amounts previously presented separately within cash flows from operating activities (i.e., to present activity related to proceeds and expenditures of real estate development/other property for sale – normal operating activity in the Company's Land Operations segment – on a net basis similar to the presentation of changes in other inventories held by the Company).
