Segment Reporting [Abstract]

Business Segments

Business Segments

We have two reportable segments: conventional real estate operations and affordable real estate operations. Our conventional real estate operations consist of market-rate apartment communities with rents paid by the residents and included 143 apartment communities with 41,425 apartment homes at June 30, 2015. Our affordable real estate operations consisted of 56 apartment communities with 8,685 apartment homes at June 30, 2015, with rents that are generally paid, in whole or part, by a government agency.

Due to the diversity of our economic ownership interests in our apartment communities, our chief executive officer, who is our chief operating decision maker, uses proportionate property net operating income to assess the operating performance of our apartment communities. Proportionate property net operating income reflects our share of rental and other property revenues less direct property operating expenses, including real estate taxes, for the consolidated and unconsolidated apartment communities that we own.

The following tables present the revenues, net operating income (loss) and income (loss) from continuing operations of our conventional and affordable real estate operations segments on a proportionate basis (excluding amounts related to apartment communities sold or classified as held for sale) for the three and six months ended June 30, 2015 and 2014 (in thousands):

(1) Represents adjustments for the noncontrolling interests in consolidated real estate partnerships’ share of the results of our consolidated apartment communities and the results of consolidated apartment communities that we do not manage, which are excluded from our measurement of segment performance but included in the related consolidated amounts, and our share of the results of operations of our unconsolidated real estate partnerships that we manage, which are included in our measurement of segment performance but excluded from the related consolidated amounts.

(2) Our basis for assessing segment performance excludes the results of apartment communities sold or classified as held for sale. In the segment presentation above, the current year and prior year operating results for apartment communities sold or classified as held for sale during 2015 or 2014 are presented within the Corporate and Amounts Not Allocated to Segments column. Proportionate property net operating income, our key measurement of segment profit or loss, also excludes property management expenses and casualty gains and losses (which are included in property operating expenses) and depreciation and amortization. Accordingly, we do not allocate these amounts to our segments and they are presented within the Corporate and Amounts Not Allocated to Segments column.

For the six months ended June 30, 2015 and 2014, capital additions related to our conventional segment totaled $156.6 million and $178.2 million, respectively, and capital additions related to our affordable segment totaled $4.5 million and $3.6 million, respectively.
