Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3 - Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of the Company were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. Liquidation Basis of Accounting As a result of the approval of the Liquidation Plan by the stockholders, the Company adopted the liquidation basis of accounting as of January 1, 2017 and for the periods subsequent to December 31, 2016 in accordance with GAAP. Accordingly, on January 1, 2017, the carrying value of the Company’s assets were adjusted to their liquidation value, which represents the estimated amount of cash that the Company will collect on disposal of assets as it carries out its liquidation activities under the Liquidation Plan. The current estimate of net assets in liquidation has been calculated based on undiscounted cash flow projections that all the properties will be sold by July 31, 2018 except for the remaining interest in Worldwide Plaza. The Company projects that the remaining interest in Worldwide Plaza will be sold approximately during the fourth quarter of 2021. The actual timing of sales has not yet been determined and is subject to future events and uncertainties. These estimates are subject to change based on the actual timing of future asset sales. The liquidation value of the Company’s investments in real estate is based on expected sales proceeds presented on an undiscounted basis. Estimated costs to dispose of assets have been presented separately from the related assets. Liabilities are carried at their contractual amounts due as adjusted for the timing and other assumptions related to the liquidation process. The Company accrues costs and revenues that it expects to incur and earn as it carries out its liquidation activities through the end of the projected liquidation period to the extent it has a reasonable basis for estimation. Estimated costs expected to be incurred through the end of the liquidation period include budgeted property expenses and corporate overhead, costs to dispose of the properties, mortgage interest expense, costs associated with satisfying known and contingent liabilities and other costs associated with the winding down and dissolution of the Company. Revenues are based on in-place leases plus management’s estimates of revenue upon re-lease based on current market assumptions. These amounts are classified as a net liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statement of Net Assets. Actual costs and revenues may differ from amounts reflected in the consolidated financial statements due to the inherent uncertainty in estimating future events. These differences may be material. See Note 4 for further discussion. Actual costs incurred but unpaid as of March 31, 2018 and December 31, 2017 are included in accounts payable, accrued expenses and other liabilities on the Consolidated Statement of Net Assets. As a result of the change to the liquidation basis of accounting, the Company no longer presents a Consolidated Balance Sheet, a Consolidated Statement of Operations and Comprehensive Income (Loss), a Consolidated Statement of Changes in Equity or a Consolidated Statement of Cash Flows. Use of Estimates Certain of the Company’s accounting estimates are particularly important for an understanding of the Company’s financial position and results of operations and require the application of significant judgment by management. As a result, these estimates are subject to a degree of uncertainty. The Company is required to estimate all costs and revenue it expects to incur and earn through the end of liquidation including the estimated amount of cash it expects to collect on the disposal of its assets and the estimated costs to dispose of its assets. All of the estimates and evaluations are susceptible to change and actual results could differ materially from the estimates and evaluations. Revenue Recognition Under liquidation basis of accounting, the Company has accrued all revenue that it expects to earn through the end of liquidation to the extent it has a reasonable basis for estimation. Revenues are accrued based on contractual amounts due under the leases in place over the estimated hold period of each asset. These amounts are classified within liability for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statement of Net Assets. In accordance with liquidation accounting, as of January 1, 2017, tenant and other receivables were adjusted to their net realizable values. Management continually reviews tenant and other receivables to determine collectability. Any changes in the collectability of the receivables is reflected in the net realizable value of the receivable. The Company owns certain properties with leases that include provisions for the tenant to pay contingent rental income based on a percent of the tenant’s sales upon the achievement of certain sales thresholds or other targets which may be monthly, quarterly or annual targets. Contingent rental income is not contemplated under liquidation accounting unless there is a reasonable basis to estimate future receipts. Investments in Real Estate As of January 1, 2017, the investments in real estate were adjusted to their estimated net realizable value upon sale, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash the Company expects to collect on the disposal of its assets as it carries out the liquidation activities of its Liquidation Plan. The liquidation value of the Company’s investments in real estate are presented on an undiscounted basis. Estimated revenue during the period following the commencement of liquidation and prior to the expected sale date and costs to dispose of these assets are presented separately from the related assets. Subsequent to January 1, 2017, all changes in the estimated liquidation value of the investments in real estate are reflected as a change in the Company’s net assets in liquidation presented on an undiscounted basis. The liquidation value of investments in real estate is based on a number of factors including discounted cash flow and direct capitalization analyses, detailed analysis of current market comparables and broker opinions of value, and binding purchase offers to the extent available. Investment in Unconsolidated Joint Venture The Company accounts for its investment in unconsolidated joint venture under the equity method of accounting because the Company exercises significant influence over, but does not control the entity and is not considered to be the primary beneficiary. Under liquidation accounting, the investment in unconsolidated joint venture is recorded at its net realizable value. The Company evaluates the net realizable value of its unconsolidated joint venture at each reporting period. Any changes in net realizable value will be reflected as a change in the Company’s net assets in liquidation. The liquidation value of the Company’s remaining investment in Worldwide Plaza as of March 31, 2018 is based on the value of the property as a result of the Company’s recent sale of its 48.7% interest in Worldwide Plaza. Amortization Under liquidation accounting, intangible assets and liabilities are included in the liquidation value of investments in real estate and are no longer amortized. Restricted Cash Restricted cash primarily consists of the $90.7 million capital improvement reserve for Worldwide Plaza with the balance representing maintenance, real estate tax, structural and debt service reserves. *Recent Accounting Pronouncement* There are no new accounting pronouncements that are applicable or relevant to the Company under the liquidation basis of accounting.
