The forestry segment produces and sells woodfiber, sawtimber and other forest products and may sell the Company’s timber or rural land holdings. The Company’s reportable segments are strategic business units that offer different products and services.  They are each managed separately and decisions about allocations of resources are determined by management based on these strategic business units.The Company uses income (loss) before income taxes and non-controlling interest for purposes of making decisions about allocating resources to each segment and assessing each segment’s performance, which the Company believes represents current performance measures.The accounting policies of the segments are set forth in Note 2 to the Company’s consolidated financial statements contained in Item 15 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.  Total revenues represent sales to unaffiliated customers, as reported in the Company’s condensed consolidated statements of operations.  All significant intercompany accounts and transactions have been eliminated in consolidation.  The caption entitled “Other” consists of mitigation credit revenue and non-allocated corporate general and administrative expenses, net of investment income.Information by business segment is as follows: Three Months Ended  June 30, Six Months Ended  June 30, 20162015 2016 2015Operating Revenues       Residential real estate$5,796 $4,020 $12,784 $9,430Commercial real estate— 4,660 — 4,660Resorts and leisure19,794 19,318 28,544 27,121Leasing operations2,321 2,167 4,682 4,212Forestry1,603 7,664 3,724 9,470Other37 17 71 44Total operating revenues$29,551 $37,846 $49,805 $54,937        Income (loss) before income taxes:       Residential real estate$1,081 $(378) $4,439 $6Commercial real estate (548) (8) (1,148) (612)Resorts and leisure2,795 3,466 994 535Leasing operations(336) 283 (379) 483Forestry1,241 6,770 3,094 8,408Other(1,675) (8,542) 7,354 (10,016)Total income (loss) before income taxes$2,558 $1,591 $14,354 $(1,196)         June 30, 2016 December 31, 2015Total Assets:   Residential real estate$106,306 $109,791Commercial real estate60,169 62,649Resorts and leisure73,873 75,441Leasing operations81,284 81,400Forestry20,102 20,244Other642,706 633,217Total assets$984,440 $982,742 |
