Accounting Policies [Abstract]

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.

Except as referred to or implied herein, we are not presently aware of any events or circumstances arising from the COVID-19 pandemic that would require us to update our current estimates, assumptions, or the reported amounts of assets, liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Our estimates may change, however, as new events occur and additional information is obtained, any such changes will be recognized in the consolidated financial statements. Actual results could differ from those estimates.

Accounting Changes [Text Block]

Accounts Receivable and Uncollectible Tenant Revenues

In connection with the adoption of ASC Topic 842, "Leases", on January 1, 2019, we began reviewing the collectibility of both billed and accrued charges under our tenant leases each quarter on a tenant by tenant basis considering the tenant’s payment history, credit-worthiness, aging of the receivable, the tenant's operating performance and other factors. For any tenant receivable balances thought to be uncollectible, we record an offset for uncollectible tenant revenues directly to Rental Revenues on our Consolidated Statement of Operations and Comprehensive Income (Loss) for the total receivable balance, including straight-line receivables, and the tenant is transitioned to a cash basis for revenue recognition.

As a result of the above change in evaluation in uncollectible tenant revenues, the allowance for doubtful accounts was written off and an entry was recorded as of January 1, 2019 to adjust the receivables and equity balances of our Consolidated Businesses and UJVs. This resulted in a cumulative effect adjustment increasing Dividends in Excess of Net Income by $3.2 million and Non-redeemable Noncontrolling Interest by $1.8 million on our Consolidated Balance Sheet with offsetting increases in Accounts and Notes Receivable, Investment in UJVs, and Distributions in Excess of Investments In and Net Income of UJVs balances on our Consolidated Balance Sheet.

Revenue Recognition

Disaggregation of Revenue

The nature, amount, timing, and uncertainty of individual types of revenues may be affected differently by economic factors. Under Accounting Standards Codification (ASC) Topic 606, "Revenue from Contracts with Customers", we are required to disclose a disaggregation of our revenues derived from contracts with customers that considers economic differences between revenue types. The following table summarizes our disaggregation of consolidated revenues for this purpose.

	Three Months Ended June 30				Six Months Ended June 30
	2020		2019		2020		2019
Shopping center and other operational revenues	$	4,744	11,993		$	16,762	23,555
Management, leasing, and development services	824		892		1,390		2,108
Total revenue from contracts with customers	$	5,568	$	12,885	$	18,152	$	25,663

Information about Contract Balances and Unsatisfied Performance Obligations

Contract assets exist when we have a right to payment for services rendered that remains conditional on factors other than the passage of time. Similarly, contract liabilities are incurred when customers prepay for services to be rendered. Certain revenue streams within shopping center and other operational revenues may give rise to contract assets and liabilities. However, these revenue streams are generally short-term in nature and the difference between revenue recognition and cash collection, although variable, does not differ significantly from period to period. As of June 30, 2020, we had an inconsequential amount of contract assets and liabilities.

The aggregate amount of the transaction price allocated to our performance obligations that were unsatisfied, or partially unsatisfied, as of June 30, 2020 were inconsequential.
