Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(1) Basis of Presentation. The accompanying consolidated financial statements include the accounts of FRP Holdings, Inc. (the “Company” or “FRP”) inclusive of our operating real estate subsidiaries, FRP Development Corp. (“Development”) and Florida Rock Properties, Inc. (”Properties”), subsequent to the completed spin-off (the “Spin-off”) of our transportation assets into a new, publicly traded entity, Patriot Transportation Holding, Inc. (“Patriot”; stock symbol “PATI”) effective January 30, 2015. As a result of the Spin-off the former transportation segment of the Company is reported as a discontinued operation that cannot receive any corporate overhead allocation. Hence, all corporate overhead of the transportation group through the date of the spin-off is included in “corporate expense” on the Company’s consolidated income statements herein. Our investment in the 50% owned Brooksville Joint Venture and in the Riverfront Investment Partners I, LLC are accounted for under the equity method of accounting (See Note 12). These statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and the instructions to Form 10-Q and do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (primarily consisting of normal recurring accruals) considered necessary for a fair statement of the results for the interim periods have been included. Operating results for the six months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2016. The accompanying consolidated financial statements and the information included under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations" should be read in conjunction with the Company's consolidated financial statements and related notes included in the Company’s Form 10-K for the year ended September 30, 2015. Following the completion of the Spin-off of the transportation business, management conducted a strategic review of the Company’s real estate operations. As a result of this review, it was determined that the information that the Company’s chief operating decision makers regularly review for purposes of allocating resources and assessing performance, had changed. Therefore, beginning with the quarter ending March 31, 2015 (with prior periods adjusted accordingly), the Company is reporting its financial performance based on three reportable segments, Asset Management, Mining Royalty Lands and Land Development and Construction, as described below. Our Mining Royalty Lands segment stays the same, but based on our strategic review the Developed Property Rentals segment has been broken down into an Asset Management segment and a Land Development and Construction segment to reflect how management now evaluates the real estate activities previously presented in the Developed Property Rentals segment. The Asset Management segment contains all the developed buildings capable of producing current rental income; the Land Development and Construction segment contains the remaining developable land not yet developed to its eventual highest and best use potential where the Company's focus is to add further entitlements, construct vertical improvements or market the property to third parties all in an effort to bring such property to income producing status or realization of its fair market value through sales or exchange. This Land Development and Construction segment is generally in a pre-income production state where objectives are long term capital investment for eventual production of long-term rental streams or capital investment to achieve highest potential market value for sale to third parties. Prior to the quarter ending December 31, 2015 certain corporate expenses (primarily stock compensation, corporate aircraft and one-time Spin-off related expenses) were reported as “unallocated” on the Company’s consolidated income statement and were not allocated to any business segment. Effective with fiscal 2016 all corporate expenses, other than those not allocated to discontinued operations, have been allocated. Reclassifications to the appropriate prior period line items and amounts have been made to be comparable to the current presentation. See Note 3 for a breakdown of corporate expenses showing the amounts allocated to the segments and the unallocated to discontinued operations.
