We review operating and financial data for each property on an individual basis; therefore, each of our individual properties is a separate operating segment. We defined our reportable segments to be aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker ("CODM"), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (commercial, multifamily, and third-party asset management and real estate services) based on the economic characteristics and nature of our assets and services.

The CODM measures and evaluates the performance of our operating segments, with the exception of the third-party asset management and real estate services business, based on the net operating income ("NOI") of properties within each segment. NOI includes property rental revenue and other property revenue, and deducts property operating expenses and real estate taxes.

With respect to the third-party asset management and real estate services business, the CODM reviews revenue streams generated by this segment ("Third-party real estate services, including reimbursements"), as well as the expenses attributable to the segment ("General and administrative: third-party real estate services"), which are both disclosed

separately in our statements of operations. The following represents the components of revenue from our third-party real estate services business:

(1)	Represents reimbursement of expenses incurred by us on behalf of third parties, including allocated payroll costs and amounts paid to third-party contractors for construction management projects.

Management company assets primarily consist of management and leasing contracts with a net book value of $28.5 million and $31.5 million and are classified in "Other assets, net" in our balance sheets as of June 30, 2020 and December 31, 2019. Consistent with internal reporting presented to our CODM and our definition of NOI, the third-party asset management and real estate services operating results are excluded from the NOI data below.

The following is the reconciliation of net income (loss) attributable to common shareholders to consolidated NOI:
