(“Development”) and Florida Rock Properties, Inc. (”Properties”) and RiverFront Investment Partners I, LLC. Our investment in the Brooksville joint venture, BC FRP Realty joint venture, RiverFront Holdings II joint venture, Bryant Street Partnerships, 1800 Half Street and Greenville/Woodfield are accounted for under the equity method of accounting (See Note 11). Our ownership of RiverFront Investment Partners I, LLC includes a non-controlling interest representing the ownership of our partner. The Company uses the cost method to account for its investment in DST Hickory Creek because it does not have significant influence over operating and financial policies.

One warehouse property valued at $11.7 million was excluded from the sale due to the tenant exercising its right of first refusal to purchase the property. On June 28, 2019, the Company completed the sale of the excluded property to the same buyer for $11.7 million. This resulted in the disposition of all of the Company’s industrial flex/office warehouse properties prior to the sale date and constituted a major strategic shift and as a result, these properties have been reclassified as discontinued operations for all periods presented.
