History

50 South was a Delaware corporation formed to purchase, own and operate a twelve-story multi-tenant office and retail building containing approximately 498,768 rentable square feet of space located in downtown Minneapolis, Minnesota (the “Property”). 50 South operated in a manner intended to qualify as a real estate investment trust, or REIT, for federal income tax purposes.

50 South was organized in September 2006 by FSP Investments LLC, a wholly-owned subsidiary of Franklin Street Properties Corp. (“Franklin Street”) (NYSE MKT: FSP). FSP Investments LLC acted as a real estate investment firm and broker/dealer with respect to (a) the organization of 50 South, (b) the acquisition of the Property by 50 South and (c) the sale of equity interests in 50 South.

50 South purchased the Property from an unaffiliated third party for $127,000,000 on November 8, 2006.

50 South commenced operations in 2006.

Franklin Street held the sole share of 50 South’s common stock, $.01 par value per share. Between November 2006 and January 2007, FSP Investments LLC completed the sale on a best efforts basis of 700 shares of the Company’s preferred stock, $.01 par value per share. 50 South sold the preferred stock for an aggregate consideration of approximately $70,000,000 in a private placement offering to 627 “accredited investors” within the meaning of Regulation D under the Securities Act of 1933. Between November 13, 2006 and January 9, 2007, 50 South held six investor closings, at each of which shares of preferred stock were sold and funds were received.

Overview of Sale of the Property, Plan of Dissolution and Trust Agreement

On May 8, 2014, the Board of Directors of 50 South approved (i) the sale of the Property to an unaffiliated third-party buyer for a gross sales price of no less than $164,500,000 and (ii) the subsequent dissolution and liquidation of 50 South pursuant to a Plan of Complete Dissolution and Liquidation (the “Plan of Dissolution”), intended to allow for the orderly disposition of 50 South’s remaining assets and liabilities. On August 18, 2014, 50 South received the required vote of the stockholders to approve the Plan of Dissolution. The Plan of Dissolution provided the Board of Directors with the authority to transfer 50 South’s remaining assets and liabilities to a liquidating trust without further approval by its stockholders, in order to complete the Plan of Dissolution.

On June 25, 2014, 50 South entered into an agreement (the “Purchase and Sale Agreement”) with Union Investment Real Estate GmbH, an unaffiliated third-party, for the sale of the Property for a gross sales price of $164,500,000.

On August 22, 2014, 50 South and FSP Property Management LLC, as Trustee (the “Trustee”), formed the Trust by entering into the Liquidating Trust Agreement (as amended, the “Trust Agreement”), for the creation and operation of the FSP 50 South Tenth Street Corp. Liquidating Trust. FSP Property Management LLC previously served as 50 South’s asset manager and is a wholly-owned subsidiary of Franklin Street. The Trust’s activities are restricted to the conservation and protection of the assets transferred by 50 South to the Trust and the administration thereof, including the payment of any liabilities, costs and expenses of 50 South or the Trust. The Trust will terminate upon the earlier of the distribution of all of the Trust’s assets in accordance with the terms of the Trust Agreement, or the expiration of a period of three years from the effective date of the Trust. The existence of the Trust may, however, be extended for up to two additional one-year periods in the Trustee’s reasonable discretion. The beneficial interests in the Trust are not transferable except by will, intestate succession or by operation of law. Any beneficial interests in the Trust transferred by will, intestate succession or by operation of law will thereafter be subject to such transfer restrictions.

On September 2, 2014, 50 South consummated the sale of the Property to Union Investment Real Estate GmbH, an unaffiliated third-party, for a gross sales price of $164,500,000.

On September 3, 2014, 50 South filed its certificate of dissolution with the Secretary of State of the State of Delaware, which became effective on that date, and transferred its remaining net assets (consisting primarily of cash) totaling $66,728,103 to the Trust. Upon the transfer of the assets and liabilities to the Trust, 50 South’s stock records were closed, all of the outstanding shares of 50 South’s preferred and common stock were cancelled, and each stockholder of 50 South automatically became the holder of one unit of beneficial interest in the Trust for each one share of 50 South’s preferred stock then currently held of record by such stockholder. The rights of beneficiaries in their beneficial interests are not represented by any form of certificate or other instrument. Stockholders of 50 South on September 3, 2014 were not required to take any action to receive units of beneficial interests. On the date of the conversion, the economic value of one unit of beneficial interest in the Trust was equivalent to the economic value of one share of 50 South’s preferred stock.

Although 50 South’s dissolution was effective on September 3, 2014, Section 278 of the General Corporation Law of the State of Delaware provides that 50 South’s existence continues for at least three years after dissolution for limited purposes. Specifically, 50 South will continue to exist for the purpose of prosecuting and defending suits, whether civil, criminal or administrative, by or against it, and enabling 50 South gradually to settle and close its business, to dispose of and convey its property, to discharge its liabilities and to distribute to its stockholders any remaining assets, but not for the purpose of continuing the business for which 50 South was organized.

On September 3, 2014, FSP 50 South Tenth Street LLC, a wholly-owned subsidiary of 50 South, filed a certificate of cancellation with the Secretary of State of the State of Delaware, which became effective upon filing.

On September 3, 2014, following the dissolution of 50 South, the Trustee authorized, pursuant to the Trust Agreement, an initial liquidating distribution of a total of $64,400,000 to the beneficial unit holders of the Trust, which amount was to be apportioned pro rata according to the beneficial unit holders’ respective interest in the Trust as of September 3, 2014. The initial liquidating distribution was effected on September 19, 2014. After giving effect to the initial liquidating distribution, as of September 19, 2014, the Trust retained approximately $2,783,149 in assets, comprised of $879,736 in cash and cash equivalents, the right to receive up to $1,645,000 in escrow proceeds in accordance with the terms of the Purchase and Sale Agreement and related documents, and $258,413 in receivables, in order to wind up 50 South’s affairs, resolve any claims and discharge any liabilities of 50 South during 50 South’s continued existence under the General Corporation Law of the State of Delaware as described above. As of September 19, 2014, the known liabilities of 50 South were estimated to be approximately $459,571, primarily consisting of accounts payable and accrued expenses, taxes and professional fees, and the Trust has estimated that it will incur approximately $300,000 in costs related to the liquidation, including legal expenses, accounting expenses, tax reporting expenses, contractor services, and miscellaneous other expected future costs.

On October 20, 2014, 50 South filed a Form 15 with the SEC to terminate the registration of 50 South’s preferred stock under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”).

On November 14, 2014, the Trust received a no-action letter (the “No Action Letter”) from the SEC stating that the Trust would not be required to register the units of beneficial interests under the Exchange Act if it operated as described in that letter. Pursuant to the No Action Letter and the Trust Agreement, the Trust’s activities are restricted to the liquidation of the assets and liabilities transferred by 50 South to the Trust, and distributing the proceeds therefrom to the beneficiaries, and paying all liabilities, costs and expenses of 50 South and the Trust. Under the No Action Letter, the Trustee agreed to file Annual Reports on Form 10-K with unaudited financial statements and Current Reports on Form 8-K upon the occurrence of a material event relating to the Trust with the SEC. The Trust is not required to file periodic reports on Form 10-Q, file proxy statements, or present its financial statements in an interactive format through the use of XBRL under the terms of the No Action Letter.

Distributions

The Plan of Dissolution provides that liquidating distributions will be made to the beneficiaries as determined by the Trustee. On September 19, 2014, the Trust effected the conveyance of the initial liquidating distribution to the holders of units of beneficial interest in the Trust of a total of $64,400,000 pursuant to the Plan of Dissolution. On June 11, 2015, the Trust effected the conveyance of the second liquidating distribution to the holders of units of beneficial interest in the Trust of a total of $1,750,000 pursuant to the Plan of Dissolution.

Tax Treatment

For Federal income tax purposes, the Trust is treated as a “grantor” trust. As such, the Trust itself is not subject to Federal income tax. Instead, each beneficiary will be treated as having a direct interest in an allocable pro rata share of each asset and liability of the Trust. As a result, an allocable portion of all items of Trust income, deductions and credits must be reported by beneficiaries on their income tax return(s).

The Trust has issued an annual information statement to our beneficiaries with tax information for their 2015 tax returns. Beneficiaries are urged to consult with their own tax advisers as to their own filing requirements and the appropriate tax reporting of this information on their returns.

Segment Information

We do not report segment information.

Employees

We have no employees or executive officers. All of our work is performed by the Trustee directly or through contract services.

Item 1A. Risk Factors

Risk associated with our liquidation.

In addition to other information in this annual report on Form 10-K, the following risk factors should be carefully reviewed because such factors may have a significant impact on the execution of the Plan of Dissolution and the timing and amount of future liquidating distributions, if any, to our beneficial unit holders. As a result of the risk factors set forth below and elsewhere in this Form 10-K, actual results could differ materially from those projected in any forward-looking statements.

We cannot assure you of the exact amount or timing of any future distribution to our beneficial unit holders.

The liquidation and dissolution process is subject to numerous uncertainties and may result in less than anticipated or no remaining capital available for future distribution to our beneficial unit holders. The precise nature, amount and timing of any future distribution to our beneficial unit holders will depend on and could be delayed by, among other things, currently unknown creditor claims or lawsuits and unexpected or greater than expected expenses. Furthermore, we cannot provide any assurances that we will actually make additional distributions.

We will continue to incur liabilities and expenses that will reduce the amount available for distribution out of the liquidation to beneficial unit holders.

Liabilities and expenses from operations, such as legal, accounting and investor services fees and other operating expenses, will continue to be incurred as we complete the Plan of Dissolution. These expenses and liabilities will reduce the amount of assets available for future distribution to beneficial unit holders.

If our existing contingency reserve for payment of our expenses and liabilities is inadequate, the amount available for distribution to beneficial unit holders could be reduced, or if any liability exceeds our remaining assets, each beneficial unit holder could be held liable for payment to our creditors of his or her pro rata share of amounts owed to creditors in excess of the Trust’s remaining assets, up to the amount actually distributed to each such beneficial unit holder.

Although the liability of any beneficial unit holder is limited to the amounts received by such beneficial unit holder, both as a stockholder of 50 South, and as a beneficiary of the Trust, from either 50 South or the Trust in the liquidation process, a beneficiary could be required to return all distributions previously made to such stockholder/beneficiary and receive nothing from us, if amounts required to settle the Trust’s remaining liabilities exceed available assets. Moreover, in the event a stockholder/beneficiary has paid taxes on amounts previously received, a repayment of all or a portion of such amount could result in the beneficial unit holder incurring a net tax cost if the beneficial unit holder’s repayment of an amount previously distributed does not cause a commensurate reduction in taxes payable. While we have endeavored to make adequate reserves for all known and contingent liabilities, there is no guarantee that the reserves established by us, or our remaining assets will be adequate to cover all such expenses and liabilities.

We may be subject to final examinations by taxing authorities across various jurisdictions, which may impact the amount of taxes that we pay and the ultimate distributions to our beneficiaries.

The Trust evaluates its probable exposures associated with the tax filing positions of both 50 South and the Trust. At December 31, 2015, the Trust believes it has no such exposures, and accordingly has not accrued any such charges. Significant judgment is required in determining the Trust’s provision for income taxes payable, and as a result, the Trust’s determinations may not prove to be accurate. 50 South and/or the Trust may be subject to final examination by taxing authorities; thus, a final determination by the taxing authorities could increase or decrease amounts of cash available for distribution to our stockholders, perhaps significantly.

A Successor Trustee may need to be appointed to complete the Plan of Dissolution, which could delay the final distribution and closing of the Trust.

The Trust Agreement provides that in the event of death, resignation or removal of the Trustee, a successor trustee will be appointed. In such event, there may be a delay in the administration of the Trust while the successor trustee is appointed and takes office, which may delay the final liquidating distribution, if any, and the closure of the Trust

Distributions

Forward-Looking Statements

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements represent our current expectations, assumptions, estimates and projections about the FSP 50 South Tenth Street Corp. Liquidating Trust . These forward-looking statements include estimates of the net assets of the Trust, statements about the amount and timing of the payment of additional liquidating distributions and statements about the Trust’s operating costs through termination of the Trust, which will vary with the length of time it operates. The forward-looking statements in this report are subject to a number of significant risks and uncertainties, and there can be no assurance that the expectations reflected in those statements will be realized or achieved. Such risks and uncertainties include, without limitation, the risk that the Trust may not be able to realize its current estimate of the net value of its assets; the risk that the Trust may have underestimated its obligations and liabilities, including without limitation, operating expenses incurred in connection with carrying out the Plan of Dissolution, liabilities and obligations of 50 South or the Trust, discharge of any outstanding creditor claims, and the termination of the Trust. See Item 1A, “Risk Factors” for additional information regarding certain of these risks and uncertainties. In light of these risks, uncertainties and assumptions, readers are cautioned not to place undue reliance on such forward-looking statements. These forward-looking statements represent beliefs and assumptions only as of the date of this report. Except as required by applicable law, we do not intend to update or revise forward-looking statements contained in this report to reflect future events or circumstances.

History

50 South purchased the Property from an unaffiliated third party for $127,000,000 on November 8, 2006.

50 South commenced operations in 2006.

Overview of Sale of the Property, Plan of Dissolution and Trust Agreement

On September 2, 2014, 50 South consummated the sale of the Property to Union Investment Real Estate GmbH, an unaffiliated third-party, for a gross sales price of $164,500,000.

Liquidation Basis of Accounting and Plan of Dissolution

The accompanying financial statements have been prepared on the liquidation basis of accounting. Under the liquidation basis of accounting, assets are stated at their estimated net realizable values and liabilities are stated at their estimated settlement amounts. The precise nature, amount and timing of any future distribution to our beneficial unit holders will depend on and could be delayed by, among other things, claim settlements with creditors, new claims filed by third parties, whether our insurance policies will provide coverage for defense costs and any damages payable on any future litigation matters, and unexpected or greater than expected expenses. Claims, liabilities and future expenses for operations, although currently declining in the aggregate, will continue to be incurred until termination of the Trust. These costs will reduce the amount of net assets available for ultimate distribution to beneficial unit holders

Critical Accounting Policies

Although our financial statements and accompanying notes are prepared without audit, they continue to be prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable sections of Regulation S-X promulgated by the SEC. The preparation of these financial statements requires us to use estimates and assumptions that affect reported amounts of assets and liabilities. These estimates are subject to known and unknown risks, uncertainties and other factors that could materially impact the amounts reported and disclosed in the financial statements. We believe the following to be among the most critical judgment areas in the application of our accounting policies.

Liquidation Basis of Accounting

The liquidation basis of accounting was adopted by 50 South in executing the Plan of Dissolution for all periods subsequent to September 3, 2014, and will continue as the basis of accounting for the Trust.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The liquidation basis of accounting requires us to make assumptions, judgments and estimates that can have a significant impact on our reported net assets in liquidation. We base our assumptions, judgments and estimates on the most recent information available and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. Any increases in the amount of estimated costs to be incurred during liquidation or decreases in the estimated realizable value of assets will reduce the amount of net assets available for ultimate distribution to the trust beneficiaries

On a regular basis, we evaluate our assumptions, judgments and estimates and make changes accordingly. Under the liquidation basis of accounting, we accrue for the estimated remaining costs to be incurred during liquidation, including expenses of the Trustee, legal expenses, accounting expenses, tax expenses, contractor services, and miscellaneous other expected future costs. As of December 31, 2015 and 2014, such costs were estimated at approximately $200,000 and $250,000, respectively. Our estimates are based on assumptions regarding costs to be incurred in executing the Plan of Dissolution. If there are delays in executing the Plan of Dissolution, actual costs incurred during liquidation may increase, reducing net assets available in liquidation.

Net Assets in Liquidation and Changes in Net Assets in Liquidation

On September 3, 2014, the remaining net assets of 50 South, totaling $66,728,000, were transferred to the Trust. As of December 31, 2014, net assets in liquidation of the Trust totaled $2,028,000.

As of December 31, 2015, net assets in liquidation of the Trust totaled $278,000, as follows:

Assets

As of December 31, 2015 and 2014, the Trust retained approximately $515,000 and $2,403,000 in assets, respectively. As of December 31, 2015, all $515,000 of the assets are comprised of cash and cash equivalents. As of December 31, 2014, assets comprised of $570,000 in cash and cash equivalents, the right to receive up to $1,645,000 in escrow proceeds in accordance with the terms of the Purchase and Sale Agreement and related documents, and $188,000 in receivables. The Purchase and Sale Agreement required 50 South to deposit $1,645,000 in an escrow account held by a title company for a period of nine months from the closing of the sale of the Property on September 2, 2014 as security for any claim made by the buyer for breach of any of 50 South’s representations in the Purchase and Sale Agreement. All of these funds were returned to the Trust on June 2, 2015.

Liabilities

As of December 31, 2015 and 2014, the Trust retained approximately $37,000 and $125,000 in liabilities, respectively, comprised of accounts payable, accrued expenses, taxes and professional fees and the Trust has estimated that it will incur approximately $200,000 and $250,000, respectively, in costs related to the liquidation, including legal expenses, accounting expenses, tax reporting expenses, contractor services, and miscellaneous other expected future costs.

Statement of Operations

The financial statements of the Trust are prepared on a liquidation basis and therefore do not include a statement of operations; all references to the results of operations have been deleted and replaced by references to changes in net assets.

The decrease in our net assets in liquidation is the result of the Trustee having authorized, pursuant to the Trust Agreement, a second liquidating distribution of a total of $1,750,000 to the beneficial unit holders of the Trust, which amount was to be apportioned pro rata according to the beneficial unit holders’ respective interest in the Trust as of June 11, 2015.

Net assets in liquidation decreased $64,400,000 or $92,000 per unit, during the period September 3, 2014 to December 31, 2014. The decrease in our net assets in liquidation is the result of the Trustee having authorized, pursuant to the Trust Agreement, an initial liquidating distribution of a total of $64,400,000 to the beneficial unit holders of the Trust, which amount was to be apportioned pro rata according to the beneficial unit holders’ respective interest in the Trust as of September 3, 2014.

Liquidity and Capital Resources

We believe that our cash and cash equivalents balance of approximately $515,000 should provide sufficient liquidity to meet our cash needs during the next twelve months from December 31, 2015. While we anticipate that our existing cash and cash equivalents balance will be sufficient to fund our cash needs for expenses related to completion of the Plan of Dissolution for the next twelve months, we can provide no assurances that this will be the case.

At December 31, 2015, our cash and cash equivalents were held in bank deposit accounts. We expect to continue to hold our cash and cash equivalents primarily in bank deposit accounts while we execute the Plan of Dissolution.

Off Balance Sheet Arrangements

As of December 31, 2015, we did not have any off-balance sheet arrangements or other contractually narrow or limited purpose arrangements. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships

Obligations and Commitments

Our contractual obligations and commitments as of December 31, 2015 are reported in the statements of net assets in liquidation as estimated costs to be incurred during liquidation. Obligations and commitments of the Trust include the Trust Agreement, the purchase and sale agreement relating to the sale of the Property, and all banking arrangements.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

(a) Evaluation of disclosure controls and procedures. Pursuant to the No-Action Letter, we maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the rules and forms, and that such information is accumulated and communicated to the Trustee, as in the case when outside contract services are used and as appropriate, to allow timely decisions regarding required disclosure.

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, an evaluation as of December 31, 2015 was conducted by our Trustee of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our Trustee concluded that our disclosure controls and procedures as of September 30, 2015 were effective for the purposes stated above.

(b) Management’s Report on Internal Control over Financial Reporting. The Trustee is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Based on the evaluation of the Trustee, our Trustee concluded that our internal control over financial reporting was effective as of December 31, 2015.

(c) Changes in internal control over financial reporting. There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2015, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Trustee’s assessment of the effectiveness of our internal controls over financial reporting was not audited. The Trustee’s report is not subject to attestation pursuant to the rules of the Securities and Exchange Commission.

Item 9B. Other Information

Not applicable.

PART III

Item 10. Directors, Executive Officers and Corporate Governance

As of December 31, 2015, we have no directors or executive officers. The Trustee manages the business affairs and assets of the Trust.

Responsibilities of our Trustee

The Trust Agreement provides that the Trustee will not be personally liable to any beneficiary or to any other party for any act it may do or omit to do as trustee while acting in good faith, except for its own gross negligence or willful misconduct. The fact that any such act or omission was advised, directed or approved by an attorney acting as attorney for the Trust will be conclusive evidence of such good faith. The Trustee has responsibility for the safekeeping and use of all of our funds and assets, whether or not they are in its immediate possession and control, and may not use or commingle funds with other person or entity or permit another to use such funds or assets in any manner except for our exclusive benefit. The Trustee may utilize the assistance of contract services or firms to assist in completing the Plan of Dissolution.

Audit Committee

The Trust does not have an audit committee or other committee that performs similar functions and, consequently, has not designated an audit committee financial expert.

Sections 16(a) Beneficial Ownership Reporting Compliance

Not Applicable.

Code of Ethics

We have not adopted a code of ethics nor do we currently intend to due to the fact that we have no employees and our Trustee manages our business and affairs subject to its fiduciary duties. Our Trustee intends to promote honest and ethical conduct, full and fair disclosure in our reports to the SEC, and compliance with applicable governmental laws and regulations.

Item 11. Executive Compensation

As of December 31, 2015, we have no directors or executive officers. The Trustee manages the business affairs and assets of the Trust. The Trustee does not receive any compensation.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

Principal Beneficiaries

There is no public market for the units of beneficial interest in the Trust. On September 3, 2014, 50 South filed its certificate of dissolution with the Secretary of State of the State of Delaware, which became effective on that date, and transferred its remaining net assets (consisting primarily of cash) totaling $66,728,000 to the Trust. Upon the transfer of the assets and liabilities to the Trust, 50 South’s stock records were closed, all of the outstanding shares of 50 South’s preferred and common stock were cancelled, and each stockholder of 50 South automatically became the holder of one unit of beneficial interest in the Trust for each one share of 50 South’s preferred stock then currently held of record by such stockholder. The units are not and will not be listed on any exchange, quoted by a securities broker or dealer, nor admitted for trading in any market, including the over-the-counter market. The beneficial interests in the Trust are not transferable except by will, intestate succession or by operation of law. Any beneficial interests in the Trust transferred by will, intestate succession or by operation of law will thereafter be subject to such transfer restrictions.

Equity Compensation Plan Information

The Trust does not have any equity compensation plans.

Item 13. Certain Relationships and Related Transactions and Director Independence

The Trustee manages our day-to-day business affairs and assets. Prior to the sale of the Property on September 2, 2014, the Trustee provided asset management services to 50 South. The Trustee is a wholly-owned subsidiary of Franklin Street.

Trust Agreement

Trustee Indemnification

Pursuant to the Trust Agreement, the Trust shall, to the maximum extent permitted by law, indemnify the Trustee against, and hold the Trustee harmless as to, any and all claims, causes of action and liabilities, including all expenses and defense costs (including reasonable attorneys’ fees), arising out of or in connection with its service as trustee under the Trust Agreement or any acts or omissions taken or omitted to be taken as trustee under the Trust Agreement, except to the extent that it is finally determined that the Trustee did not act in good faith or such actions or omissions constitute gross negligence or willful misconduct on the part of the Trustee. In the event that any legal proceeding is instituted against the Trustee, as trustee or personally, on account of any actions or omissions taken by the Trustee, then prior to the final disposition of such action, the Trustee shall be entitled to cause the Trust to advance to the Trustee such fees and costs as are reasonably incurred by the Trustee in defending against such action.

Investor Services Agreement

On August 14, 2012, we entered into an Investor Services Agreement (the “FSPI Agreement”) with FSP Investments LLC for the provision of investor services to beneficial unit holders. FSP Investments LLC is a wholly-owned subsidiary of Franklin Street. FSP Investments LLC acted as a real estate investment firm and broker/dealer with respect to (a) 50 South’s organization, (b) 50 South’s acquisition of the Property and (c) the sale of equity interests in 50 South. The FSPI Agreement requires us to pay a monthly service fee of $500 for services performed under the FSPI Agreement, and to reimburse FSP Investments LLC for its reasonable out-of-pocket expenses incurred in connection with the FSPI Agreement. The FSPI Agreement may be terminated by either party with thirty days written notice or immediately upon certain events of default set forth in the FSPI Agreement.

Notes to Unaudited Financial Statements

Note 1. Description of Business

On August 22, 2014, 50 South and FSP Property Management LLC, as Trustee (the “Trustee”), formed the Trust by entering into the Liquidating Trust Agreement (as amended, the “Trust Agreement”), for the creation and operation of the FSP 50 South Tenth Street Corp. Liquidating Trust . FSP Property Management LLC previously served as 50 South’s asset manager and is a wholly-owned subsidiary of Franklin Street. The Trust’s activities are restricted to the conservation and protection of the assets transferred by 50 South to the Trust and the administration thereof, including the payment of any liabilities, costs and expenses of 50 South or the Trust. The Trust will terminate upon the earlier of the distribution of all of the Trust’s assets in accordance with the terms of the Trust Agreement, or the expiration of a period of three years from the effective date of the Trust. The existence of the Trust may, however, be extended for up to two additional one-year periods in the Trustee’s reasonable discretion. The beneficial interests in the Trust are not transferable except by will, intestate succession or by operation of law. Any beneficial interests in the Trust transferred by will, intestate succession or by operation of law will thereafter be subject to such transfer restrictions.

Note 2. Summary of Significant Accounting Policies

Basis of Accounting

The liquidation basis of accounting was adopted by 50 South in executing the Plan of Complete Dissolution and Liquidation (the “Plan of Dissolution”) for all periods subsequent to September 3, 2014, and will continue as the basis of accounting for the Trust. Under the liquidation basis of accounting, assets are stated at their estimated net realizable values and liabilities are stated at their estimated settlement amounts. Claims, liabilities and future expenses for operation of the Liquidating Trust will continue to be incurred until the Trust is terminated.

Use of Estimates

The preparation of financial statements in accordance with GAAP and under the liquidation basis of accounting requires us to make estimates and judgments that affect the reported amounts of assets (including net assets in liquidation), liabilities and expenses. We believe that our critical accounting policies are those that require significant judgments and estimates. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could vary from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions.

Notes to Unaudited Financial Statements

Note 2. Summary of Significant Accounting Policies (continued)

Cash and Cash Equivalents

As of December 31, 2015 and 2014, cash and cash equivalents total approximately $515,000 and $570,000, respectively, which consist of funds held in bank deposit accounts. Cash equivalents are stated at costs plus accrued interest approximates market value.

Restricted Cash

As of December 31, 2014, restricted cash was approximately $1,645,000 representing funds held in an escrow account by a title company as security for any claim of breach of any of 50 South’s representations in the purchase and sale agreement signed in connection with the sale of 50 South’s real property on September 2, 2014. Funds were returned to the Trust on June 2, 2015 and were used for additional liquidating distributions made in 2015.

Recent Accounting Pronouncements

There are no previously issued or new accounting pronouncements or changes in accounting pronouncements that have had, or are expected to have a material impact on the Trust’s financial statements.

Concentration of Credit Risk - Financial Instruments

Financial instruments that subject the Trust to a concentration of credit risk consist of cash and cash equivalents and restricted cash balances maintained in financial institutions that are, in part, in excess of Federal Deposit Insurance Corporation (“FDIC”) limits. As of December 31, 2015 and 2014, the Trust held cash and cash equivalents and restricted cash of approximately $265,000 and $1,715,000, respectively, in excess of the FDIC insurance limits.

Financial Instruments

Our net assets in liquidation as of December 31, 2014 include the following financial instruments: cash and cash equivalents and accrued expenses. As our financial statements have been prepared under the liquidation basis of accounting, the carrying values of these instruments classified as assets and liabilities represent their estimated net realizable values and estimated settlement amounts, respectively.

Costs to be incurred during liquidation

Under the liquidation basis of accounting, we accrue for the estimated remaining costs to be incurred during liquidation, including legal expenses, accounting expenses, tax reporting expenses, contractor services, and miscellaneous other expected future costs. As of December 31, 2015 and 2014, such costs were estimated at approximately $200,000 and $250,000, respectively. Our estimates are based on assumptions regarding costs to be incurred in executing the Trust Agreement, as described above in Note 1. The actual costs incurred during liquidation may increase, reducing net assets available in liquidation.

Income Taxes

We are treated as a grantor trust for federal income tax purposes and accordingly, will not be subject to federal or state income tax on any income earned or gain recognized by us. Our beneficiaries will be treated as the owner of a pro rata portion of each asset, including cash, received by and held by us and will be required to report on his or her federal, state or foreign tax return his or her pro rata share (per unit) of taxable income, including gains and losses recognized by us. Accordingly, there is no provision for federal or state income taxes in the accompanying financial statements.
