Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements and related disclosures included herein are presented in accordance with United States generally accepted accounting principles (“GAAP”) and include the account balances and transactions of consolidated subsidiaries, which are wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Liquidity	Going Concern The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. We incurred net losses of $14.3 million and $17.4 million for the years ended December 31, 2015 and 2014, respectively, and have incurred cumulative net losses since inception of $229.0 million. We have a substantial amount of debt maturing in 2016 for which the Company does not have committed funding sources. We have a stockholders’ deficit of $153.1 million at December 31, 2015. These conditions raise substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent upon obtaining the necessary financing to continue operations (including the refinancing of maturing debt), generating profitable operations in the future and developing and implementing our strategic plan to address these needs. No assurance can be given that we will be successful in these efforts. To meet our capital needs, we may consider strategic alternatives, including a sale, merger, other business combination or recapitalization, of the Company. In January 2016, we engaged Eastdil Secured to assist in this effort. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary if we are unable to continue as a going concern. We believe that our actions presently being taken to obtain additional funding and implement our strategic plans provide the opportunity for the Company to continue as a going concern. No assurance can be given that we will be successful in these efforts. Liquidity Our business is capital intensive and our ability to maintain our operations depends on our cash flow from operations and our ability to raise additional capital on acceptable terms. Our primary focus is to preserve and generate cash. We are working to address challenges to our liquidity position, particularly with respect to mortgage debt on each of our wholly-owned properties that is scheduled to mature in 2016. We do not currently have any committed financing sources available to refinance our debt as it matures. If we are unable to repay, extend or refinance our existing mortgage debt, we may be forced to give back one or more of these assets to the relevant mortgage lenders. We expect to meet our short-term liquidity and capital requirements primarily through existing cash on hand, net cash provided by rental activities, refinancing of existing debt, distributions from joint ventures and/or asset dispositions. We expect to meet our long-term capital requirements through net cash provided by operating activities, borrowings under our revolving credit facility (if available), refinancing of existing debt or through other available investment and financing activities, including the contribution of existing wholly-owned assets to joint ventures (partial sell-down of equity interests in wholly-owned assets), asset dispositions and/or additional secured or unsecured debt financings. In January 2015, we completed the sale of our Clifford Center property, located in Honolulu, Hawaii, to an unaffiliated third party. The net proceeds from the sale of the Clifford Center property, after repaying the related mortgage loans and transaction-related expenses, were approximately $2.1 million. We may also consider strategic alternatives, including a sale, merger, other business combination or recapitalization, of the Company. In January 2016, we engaged Eastdil Secured to assist in the potential sale, financing or recapitalization of our remaining wholly-owned properties, but there can be no assurance that this engagement will result in a transaction. We are focused on ensuring our properties are operating as efficiently as possible. We have taken steps to identify opportunities to reduce discretionary operating costs wherever possible and at the same time maintaining the quality of our buildings and the integrity of our management services. We have no employees and rely upon our advisor to provide substantially all of our day-to-day management. We believe that Shidler Pacific Advisors can provide adequate personnel resources, at lower cost to us, for our current and prospective business. Effective January 1, 2015, Shidler Pacific Advisors agreed to reduce the corporate management fee payable by us from $0.21 million per quarter to $0.18 million per quarter. Capital expenditures fluctuate in any given period, subject to the nature, extent and timing of improvements required to maintain our properties. Leasing costs also fluctuate in any given period, depending upon such factors as the type of property, the term of the lease, the type of lease and overall market conditions. Our costs for capital expenditures and leasing fall into two categories: (1) amounts that we are contractually obligated to spend and (2) discretionary amounts. As of December 31, 2015, we were obligated to spend $3.0 million in capital expenditures and leasing costs through 2016. As of December 31, 2015, our total consolidated debt (which includes our mortgage and other loans with a carrying value of $290.9 million and our unsecured promissory notes with a carrying value of $29.4 million) was $320.3 million, with a weighted average interest rate of 5.78% and a weighted average remaining term of 0.78 years. As of December 31, 2015, we had a fully-drawn $25.0 million unsecured credit facility scheduled to mature on December 31, 2016. We also had promissory notes payable to certain current and former affiliates in the aggregate outstanding principal amount of $29.4 million (together with accrued and unpaid interest of $15.6 million) scheduled to mature on December 31, 2016. While we may be able to anticipate and plan for certain liquidity needs, there may be unexpected increases in uses of cash that are beyond our control and which would affect our financial condition and results of operations. For example, we may be required to comply with new laws or regulations that cause us to incur unanticipated capital expenditures for our properties, thereby increasing our liquidity needs. Even if there are no material changes to our anticipated liquidity requirements, our sources of liquidity may be fewer than, and the funds available from such sources may be less than, anticipated or needed.
