Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements and condensed notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), including Subtopic 205-30, “Liquidation Basis of Accounting,” as indicated, and the rules and regulations of the Securities and Exchange Commission, including the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the financial statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Pursuant to the Company’s stockholders’ approval of the Plan of Liquidation, the Company adopted the liquidation basis of accounting as of and for the periods subsequent to February 1, 2020 (as the approval of the Plan of Liquidation by the Company’s stockholders became imminent within the first week of February 2020 based on the results of the Company’s solicitation of proxies from its stockholders for their approval of the Plan of Liquidation). Accordingly, on February 1, 2020, assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash that the Company will collect through the disposal of assets as it carries out the Plan of Liquidation. The liquidation values of the Company’s remaining real estate properties are presented on an undiscounted basis. Estimated costs to dispose of assets and estimated capital expenditures through the anticipated disposition date of the properties have been presented separately from the related assets. Liabilities are carried at their contractual amounts due or estimated settlement amounts. The Company accrues costs and income that it expects to incur and earn through the completion of its liquidation, including the estimated amount of cash the Company expects to collect through the disposal of its assets and the estimated costs to dispose of its assets, to the extent it has a reasonable basis for estimation. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the Condensed Consolidated Statement of Net Assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Liquidation” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” for further discussion. Actual costs incurred but unpaid as of March 31, 2020 are included in accounts payable and accrued liabilities, due to affiliates and other liabilities on the Condensed Consolidated Statement of Net Assets. Net assets in liquidation represents the remaining estimated liquidation value available to stockholders upon liquidation. Due to the uncertainty in the timing of the sale of the Company's remaining real estate properties and the estimated cash flows from operations, actual liquidation costs and sale proceeds may differ materially from the amounts estimated. All financial results and disclosures through January 31, 2020, prior to the adoption of the liquidation basis of accounting, are presented on a going concern basis, which contemplates the realization of assets and liabilities in the normal course of business. As a result, the balance sheet as of December 31, 2019, the statements of operations, the statements of stockholders’ equity and the statements of cash flows for the month ended January 31, 2020 and the comparative three months ended March 31, 2019 are presented using the going concern basis of accounting. Under the going concern basis of accounting, the Company’s consolidated financial statements included its accounts and the accounts of KBS REIT Holdings II, the Operating Partnership and their direct and indirect wholly owned subsidiaries. All significant intercompany balances and transactions were eliminated in consolidation. Use of Estimates The preparation of the unaudited consolidated financial statements and condensed notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and condensed notes. Actual results could materially differ from those estimates. Real Estate Liquidation Basis of Accounting As of February 1, 2020, the Company’s investments in real estate were adjusted to their estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash that the Company will collect through the disposal of its assets, including any residual value attributable to lease intangibles, as it carries out the Plan of Liquidation. The Company estimated the liquidation value of its investments in real estate based on internal valuation methodologies using a combination of the direct capitalization approach and discounted cash flow analyses and in one case an offer received which the Company intends to accept. The liquidation values of the Company’s investments in real estate are presented on an undiscounted basis and investments in real estate are no longer depreciated. Estimated costs to dispose of these investments are carried at their contractual amounts due or estimated settlement amounts and are presented separately from the related assets. Subsequent to February 1, 2020, all changes in the estimated liquidation value of the investments in real estate are reflected as a change to the Company’s net assets in liquidation. Rents and Other Receivables In accordance with the liquidation basis of accounting, as of February 1, 2020, rents and other receivables were adjusted to their net realizable value. The Company periodically evaluates the collectibility of amounts due from tenants. Any changes in the collectibility of the receivables are reflected as a change to the Company’s net assets in liquidation. Revenue Recognition Liquidation Basis of Accounting Under the liquidation basis of accounting, the Company has accrued all income that it expects to earn through the completion of its liquidation to the extent it has a reasonable basis for estimation. Revenue from tenants is estimated based on the contractual in-place leases and projected leases through the anticipated disposition date of the property. These amounts are classified in liabilities for estimated costs in excess of estimated receipts during liquidation on the Consolidated Statement of Net Assets. Accrued Liquidation Costs In accordance with the liquidation basis of accounting, the Company accrues for certain estimated liquidation costs to the extent it has a reasonable basis for estimation. These consist of legal fees, dissolution costs, final audit/tax costs, insurance, and distribution processing costs. Per Share Data Basic net income (loss) per share of common stock is calculated by dividing net income (loss) by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted net income (loss) per share of common stock equals basic net income (loss) per share of common stock as there were no potentially dilutive securities outstanding during the month of January 31, 2020 and the three months ended March 31, 2019. Distributions declared per common share were $0.062 in the aggregate for the three months ended March 31, 2019. Distributions declared per common share assumes each share was issued and outstanding each day that was a record date for distributions and were based on a monthly record date for each month during the period commencing January 2019 through March 2019. Pursuant to the Plan of Liquidation, on March 5, 2020, the Company’s board of directors authorized an initial liquidating distribution in the amount of $0.75 per share of common stock to the Company’s stockholders of record as of the close of business on March 5, 2020 (the “Initial Liquidating Distribution”).
