Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation variable interest entities

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, KSLLC, and all of our wholly-owned subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, KSLLC, and all wholly-owned subsidiaries of the Operating Partnership. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

The consolidated financial statements of the Company and the Operating Partnership also include two variable interest entities ("VIE") in which we are deemed to be the primary beneficiary.

Segment reporting

Our chief operating decision-makers internally evaluate the operating performance and financial results of our portfolio based on Net Operating Income for the following two segments of commercial real estate property: Office Properties and Industrial Properties. We define “Net Operating Income” as operating revenues (rental income, tenant reimbursements, and other property income) less operating expenses (property expenses, real estate taxes, provision for bad debts, and ground leases).

During the three and nine months ended September 30, 2011, the amount of revenues and Net Operating Income generated by our Industrial Properties, in relation to our total consolidated operating portfolio revenues and Net Operating Income fell below the required 10% quantitative reporting thresholds for the Industrial Properties to be considered a reportable segment under GAAP. Therefore, for the three and nine months ended September 30, 2011, our only reportable segment is our Office Properties segment. See Note 13 for a reconciliation of our Office Properties segment to our consolidated revenues, Net Operating Income, net income and consolidated assets.
