Independent Auditor’s Report

To the General and Limited Partners of

Wellington Management Legacy Securities PPIF Master Fund, LP

We have audited the accompanying financial statements of Wellington Management Legacy Securities PPIF Master Fund, LP (“the Fund”), which comprise the statements of assets, liabilities and partners’ capital, including the schedules of investments as of December 31, 2012 and 2011, and the related statements of operations, of changes in partners’ capital, and of cash flows for the years then ended.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on the financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Fund’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Wellington Management Legacy Securities PPIF Master Fund, LP (the “Fund”) at December 31, 2012 and 2011, and the results of its operations, changes in its partners’ capital and its cash flows for the years then ended, in accordance with accounting principles generally accepted in the United States of America.

Emphasis of Matter

As discussed in Note 9 to the financial statements, on March 6, 2013, the General Partner approved a plan to wind down the affairs of the Fund. Our opinion is not modified with respect to this matter.

Notes to Financial Statements

December 31, 2012 and December 31, 2011

(in United States Dollars)

1.	Organization

Wellington Management Legacy Securities PPIF Master Fund, LP (the “Master Fund”), a Delaware limited partnership, was formed on July 14, 2009 pursuant to the Amended and Restated Limited Partnership Agreement (“Master Fund Agreement”) and commenced operations on October 1, 2009 (“Initial Closing Date”). The general partner of the Master Fund is Wellington PPIF Management, LLC, a Delaware limited liability company (the “General Partner”). The Master Fund serves as the investment vehicle for the General Partner and its limited partners which are Wellington Management Legacy Securities PPIF, LP, a Delaware limited partnership (the “Onshore Feeder”), Wellington Management Legacy Securities PPIF (Offshore), LP, a Delaware limited partnership (the “Offshore Feeder”) and US Department of the Treasury (the “UST”) under a master-feeder structure. The Onshore Feeder and Offshore Feeder are collectively referred to as the “Private Investor Funds”. The investors in the Offshore Feeder are Wellington Management Legacy Securities PPIF (Offshore) Ltd., a Cayman Islands exempted company and Advent Legacy Securities, Ltd., a Cayman Islands exempted limited company.

The Master Fund was formed in connection with the Public-Private Investment Program (“PPIP”) as mandated by the US Emergency Economic Stabilization Act of 2008, which seeks to enable credit to flow freely and improve the balance sheets of financial institutions by creating funds to purchase troubled assets from these entities. The UST matched the aggregate commitments by the General Partner and the Private Investor Funds to the Master Fund; the Private Investor Funds received aggregate commitments from third party investors directly or indirectly through the feeders totaling approximately $1.149 billion. In addition to the USTs capital investment in the Master Fund, the UST, pursuant to the loan agreement dated October 1, 2009, will also provide a senior secured multiple-draw term loan facility (the “UST Credit Facility”) to the Master Fund of up to 100% of total capital commitment or 200% of UST capital commitment. See Note 3 for further details.

The Master Funds investment objective is to seek to generate attractive returns through long-term opportunistic investments in commercial mortgage backed securities and non-agency residential mortgage backed securities issued prior to 2009 that were originally rated AAA or an equivalent rating by two or more nationally recognized statistical rating organizations without ratings enhancement and that are secured directly by the actual mortgage loans, leases or other assets and not other securities (collectively, “Eligible Assets”). In accordance with the Master Fund Agreement, at least 90% of the assets underlying any Eligible Asset must be situated in the United States, and must be purchased solely from financial institutions from which the Secretary of the UST may purchase assets pursuant to Section 101(a)(1) of the United States Emergency Economic Stabilization Act of 2008, as amended. The Master Fund may also make temporary investments in the UST securities and certain money market mutual funds that own only instruments that are unconditionally guaranteed by the United States government. The Master Fund may not, without the written consent of the UST, invest an amount (excluding leverage) in excess of 5% of the Master Funds aggregate capital commitments in any particular issuance of Eligible Assets.

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

The Master Funds investment manager is Wellington Management Company, LLP, a Massachusetts limited liability partnership (the “Investment Manager”). Williams Capital Management has been retained by the Investment Manager as the investment sub-advisor to the Master Fund for the purpose of investing in temporary investments. Bank of New York Mellon was appointed as administrative agent, collateral agent and valuation agent.

The term of the Master Fund will continue until the dissolution date, which is October 1, 2017, unless the Master Fund is dissolved sooner in accordance with the terms of the Master Fund Agreement. However, the General Partner with written consent of the UST, may extend the term of the Master Fund for up to two consecutive one–year periods.

2.	Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Master Fund are expressed in United States Dollars and are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

Estimates

The preparation of financial statements in conformity with US 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 and the reported amounts of increases and decreases in partners capital from operations during the reporting period. Actual results could differ from those estimates and such differences could be material.

Recently Issued Accounting Pronouncements

In December 2011, Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2011-11, Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 creates new disclosure requirements about the nature of an entitys rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods therein, with retrospective application required. The new disclosures are designed to make financial statements that are prepared under US GAAP more comparable to those prepared under International Financial Reporting Standards (IFRS) and also to better facilitate comparison between financial statements prepared under US GAAP and IFRS, the new disclosures will give financial statement users information about both gross and net exposures. The Investment Manager is currently assessing the impact that the adoption of the ASU 2011-11 will have on the Master Funds financial statement disclosures.

Investment Valuation

The Master Fund values investments, including any short-term investments and derivatives, on the basis of current market quotations provided by an independent pricing service or by a broker/dealer experienced in such matters. In determining the value of a particular investment, pricing services

(in United States Dollars)

may use certain information with respect to transactions in such investments, quotations from dealers, market transactions in comparable investments, various relationships between investments and calculated yield measures based on valuation methods commonly employed in the market for such investments.

If recent quotations are not readily available for any security or if the General Partner and Wellington Management Company, LLP as Investment Manager (together “Management”) determines, in its reasonable discretion, that available estimated quotations do not fairly represent the fair value of such security, such security is valued at its fair value employing methods determined in good faith by Management. The value assigned to these securities is based upon available information including, but not limited to, the original transaction prices, recent transactions in the same or similar instruments, completed or pending third-party transactions in the underlying investment or comparable issuers, changes in financial ratios or cash flows, subsequent rounds of financing and may also be adjusted to reflect liquidity and/or transferability restrictions. Such values may not necessarily represent the amount which may ultimately be realized upon sale. Due to the inherent uncertainty of the valuation, the estimated fair value may differ from the value of the securities had a ready market existed, and the difference could be material.

Fair Value Measurements

In accordance with ASC 820, fair value is defined as the price the Master Fund would receive to sell an asset or pay for a liability in an orderly transaction between the market participants at the reporting date. ASC 820 also establishes a three-level hierarchy for presenting valuations, based on the transparency of inputs into valuation techniques used to measure fair valuation. Inputs may be observable or unobservable, and refer broadly to the assumptions that a market participant would consider significant to value an asset or liability. The determination of “observable” requires judgment. In general, the Master Fund considers observable inputs to be data readily available, regularly updated, reliable, arms-length, and verifiable. Unobservable inputs may be used when observable inputs are not readily available, current or arms-length. In this situation, the Master Fund may use one or more valuation techniques (e.g. market or income approach), using the best available information as of reporting date, along with the Master Funds own assumptions of market participant behavior.

Within Level 3, the use of market approach generally involves using inputs that are based on available market transactions or market observable comparables. The income approach is generally based on expected cash flows or earnings. Under both approaches, adjustments may be applied to reflect various risks (e.g. liquidity, financial health of the investment issuer, quality of the information available for fair value measurement).

Assets and liabilities are classified into one of the following levels, based on the lowest level of input that is significant to the fair value measurement:

Level 1 – Quoted prices available in active markets for identical investments. In general, this level includes equities and derivatives regularly traded on major exchanges. As required by ASC 820, the Master Fund does not adjust quoted prices for these investments, even when the Master Fund holds a sizable position and a block sale could impact the quoted market price.

(a Delaware limited partnership)

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

Level 2 – Quoted prices in active markets for similar investments; quoted prices for identical investments in markets that are inactive; prices based on observable inputs other than an unadjusted quoted price; and prices based on market-corroborated inputs (such as interest rates, yield curves, volatilities, prepayment rates, credit risks and default rates). This level generally includes most fixed income securities and over the counter (“OTC”) derivative instruments; securities valued in good faith by the General Partner, in consultation with the Investment Manager, using observable inputs and dealer priced securities which can be reasonably verified through an alternative source.

Level 3 – Prices based on significant unobservable inputs; Master Fund investments with significant restrictions; securities valued in good faith by the Management. In these situations, it is possible that a different valuation model could produce materially different fair value measurements. In some cases, a fair value measurement may require the use of multiple inputs, for which the General Partner must exercise judgment to determine relative significance for placement in the hierarchy. The fair value of the UST Warrant is developed internally using a discounted cash flow model. Significant inputs used include discount rate, cashflows from underlying investments, distribution rate, probability of various scenarios, which all require judgment. The categorization of a financial instrument within the hierarchy is based on price transparency and does not necessarily correspond to the perceived risk of the instrument.

The inputs or methodology used for valuing investments are not necessarily an indication of the risks associated with investing in those investments.

The following table sets forth a summary of valuation techniques and quantitative information utilized in determining the fair value of the Master Funds Level 3 investments as of December 31, 2012 and December 31, 2011.


				Significant
				Unobservable
Investment Type	Fair Value		Valuation Technique⁽¹⁾	Inputs⁽²⁾
2012 UST Warrant Payable	$	11,185,834	Income Approach - Discounted cash flow	Discount rate - 12%
2011 UST Warrant Payable	$	11,874,415	Income Approach - Discounted cash flow	Discount rate - 12%

(1)	A discounted cash flow method is generally used for performing investments in which the Master Fund does not have a controlling interest in the underlying issuer.

The significant unobservable input used in the fair value measurement of performing credit-oriented investments in which the Master Fund does not have a controlling interest in the underlying issuer is the discount rate. A significant increase (decrease) in the discount rate would result in a significantly lower (higher) fair value measurement.

The use of unobservable inputs, including assessing the accuracy of source data, and the results of pricing models requires a significant degree of judgment. The General Partner assesses the accuracy and reliability of the sources it uses to obtain unobservable inputs; these sources may include third-party vendors that the General Partner believes are reliable and commonly utilized by other market place participants.

The following tables summarizes the valuation of the Master Funds financial instruments by the above pricing observability levels as of December 31, 2012 and December 31, 2011.

The Partnerships policy is to recognize transfers in and transfers out as of the beginning of each fiscal period, generally monthly. During the years ended December 31, 2012 and December 31, 2011 there were no significant transfers in or out of Level 1, Level 2 or Level 3.

The amount of the total gains for the years ended December 31, 2012 and December 31, 2011 that are attributable to the change in unrealized gains relating to the Level 3 liability still held as of December 31, 2012 and December 31, 2011 is $688,581 and $781,077, respectively, which is reflected in net change in unrealized depreciation on UST Warrant payable on the Statements of Operations.

Collateral

The Master Fund is a party to ISDA Master Agreements with certain counterparties that govern OTC derivative contracts entered into from time to time. The Master Agreements may contain provisions regarding, among other things, the parties general obligations, representations, agreements,

Wellington Management Legacy Securities PPIF Master Fund, LP

(a Delaware limited partnership)

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

collateral requirements, events of default and early termination. Collateral can be in the form of cash, debt securities, and/or other securities as agreed to by the Master Fund and the counterparty. Collateral requirements are determined based on the Master Funds net position with each counterparty.

The Master Fund records cash collateral posted to brokers as “Swap collateral” on the Statements of Assets, Liabilities and Partners Capital. As of December 31, 2012 and December 31, 2011, $5,938,000 and $83,299,000, respectively was posted by the Master Fund.

At December 31, 2011, the Master Fund recorded as “Due to broker” amount of $1,468,000 on the Statements of Assets, Liabilities and Partners Capital which relates to additional collateral posted by the Master fund.

Swap Contracts

The Master Fund may enter into interest rate swaps as part of a strategy to manage exposure to interest rates. Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Master Fund are recorded as “Net realized gain (loss) on swap contracts” in the accompanying Statements of Operations as realized gains or losses.

Within the Statements of Assets, Liabilities and Partners Capital, swap contracts are recorded at their unrealized appreciation or (depreciation), depending on changes in their fair value and these amounts are reflected as “Unrealized appreciation or depreciation on swap contracts.” Gains or losses are realized upon early termination of any swap agreement. The change in unrealized value of swap contracts is reflected in the Statements of Operations as “Net change in unrealized appreciation (depreciation) on swap contracts.” Details of swap contracts open at December 31, 2012 and December 31, 2011 are included in the Schedules of Investments under the caption “Interest Rate Swap Contracts.”

Derivative Instruments

The provisions of ASC 815 require enhanced disclosure about the Master Funds derivatives and provides greater transparency of how and why an entity uses derivative instruments, how derivative instruments are accounted for and how they affect an entitys financial position, results of operations and cash flows. ASC 815 also requires qualitative disclosures about an entitys associated risk exposure, quantitative disclosures about fair value amounts and the gains and losses related to derivative instruments and disclosures of any credit–risk contingent feature in derivative agreements. The adoption of ASC 815 had no impact on the Statements of Assets, Liabilities and Partners Capital or the Statements of Operations.

Certain ISDA Master Agreements may contain contingent features that allow the counterparty to terminate trades executed and/or request additional collateral if the NAV of the Master Fund declines beyond certain thresholds (“NAV triggers”). At December 31, 2012 and December 31, 2011, the aggregate fair value of all derivative instruments with such contingent features in a liability position

(in United States Dollars)

was $10,256,154 and $85,655,603, respectively, for which the Master Fund posted $5,938,000 and $83,299,000 of collateral, respectively. If the credit-risk contingent features were triggered on December 31, 2012 and December 31, 2011, the Master Fund would be required to post additional collateral of $4,318,154 and $2,356,603, respectively, or potentially settle the contract in an amount equal to its fair value as noted in the Schedules of Investments.

The Master Fund may transact in a variety of derivative instruments including futures, options, swaps and swaptions for the purpose of managing interest rate risk. The primary risk exposure category and related gains or losses have been summarized in the tables below. Additionally, see Note 7 for information on the Master Funds risks related to such transactions.

The following tables present the gross value of the Master Funds derivative contracts by primary risk exposure category referenced in Note 7. The values in the table exclude the effects of cash received or posted as collateral, and therefore are not representative of the Master Funds net exposure. The fair value of these derivative instruments is reflected as “Unrealized depreciation on swap contracts” in the Statements of Assets, Liabilities and Partners Capital. Volumes reported at December 31, 2012 and December 31, 2011 are generally indicative of average positions during the year.

Investment Transactions, Investment Income and Expenses

Investment transactions are recorded on the trade date. Realized gains and losses on investment transactions are reported on the basis of specific identified cost. Interest income and expenses are recorded on the accrual basis and include accretion of discount and amortization of premium generally over the life of the respective security using the effective yield method. For those securities that are in default or otherwise determined to be deeply distressed, interest may not be accrued and, in which case, interest will be recognized only if and when received. Gains and losses realized on repayment of principal on Eligible Assets are reported as interest income in the accompanying Statements of Operations.

Income Taxes

ASC 740-10 establishes financial accounting and disclosure requirements for recognition and measurement of tax positions taken or expected to be taken on an income tax return to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable taxing authority. Tax positions deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit in the current year.

The Master Fund is treated as a partnership for U.S. federal income tax purposes and, as such, is generally not subject to U.S. federal or state income tax. Each partner of the Master Fund generally is liable for its share of all U.S. federal and state taxes, if any, imposed on the net investment income and realized gains of the Master Fund.

Wellington Management Legacy Securities PPIF Master Fund, LP

(a Delaware limited partnership)

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

No income tax liability for tax positions has been recognized in the accompanying financial statements. The Master Fund is subject to examination by U.S. Federal and State tax authorities for tax returns filed after December 31, 2009. Each partner is individually responsible for reporting income or loss, to the extent required by the federal and state income tax laws and regulations, based upon its respective share.

Cash and Cash Equivalents

The Master Fund maintains cash in a bank deposit account that, at times, may exceed U.S. federally insured limits. The Master Fund has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on such bank deposits.

The Master Fund considers investments in money market funds and short-term highly liquid investments with maturities of three months or less (when acquired) to be cash equivalents. Cash equivalents were carried at amortized cost which approximates fair value. As of December 31, 2012 and December 31, 2011, the Master Fund had money market funds of $499,739,128 and $144,665,074 respectively.

3.	Loan Agreement

The Master Fund entered into a loan agreement dated October 1, 2009, as a borrower, with the UST, as the Lender, The Bank of New York Mellon, as the Administrative and Collateral Agent (the “Loan Agreement”) under the UST Credit Facility as a result of the Master Funds participation in the PPIP. The loans borrowed from the UST Credit Facility are used to finance the purchase of Eligible Assets. The loans will be due and payable on the earliest of (i) ten years from the Initial Closing Date of the Master Fund, (ii) the date of expiration, termination or dissolution of the Master Fund, and (iii) such earlier time as the obligations of the Master Fund and the Loan Agreement and the other credit documentation with respect to the UST Credit Facility have been accelerated. The Master Fund incurs interest on the aggregate principal amount of loans, as of any date of determination, at a rate per annum equal to LIBOR plus the Applicable Margin as defined in the Loan Agreement, which was 1.21% and 1.28%, respectively as of December 31, 2012 and December 31, 2011. The non-recourse provision of the UST loans allowed the Master Fund to satisfy loan obligations with Eligible Assets, subject to certain conditions, even if the value of the Eligible Assets falls below the outstanding amount of the loan. The Master Fund could repay the UST loans prior to the maturity dates without penalty. Principal and interest due on the loans are paid with the proceeds of principal paydowns and interest received from the Eligible Assets. Credit agreements underlying each loan contain provisions to address instances in which interest payments on Eligible Assets fall short of amounts due to the UST.

The Master Fund is subject to repayment priorities as defined in the Loan Agreement and summarized below assuming no default by the Master Fund, as applicable:

(1)

administrative expenses, excluding certain tax expenses of the Master Fund;

(2)

interest due on permitted interest rate hedges;

(3)

current period loan interest due to Lender;

Wellington Management Legacy Securities PPIF Master Fund, LP

(a Delaware limited partnership)

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

(4)

amounts to the interest reserve account if the total deposit in the interest reserve account is less than the required interest reserve amount;

(5)

loan paydown amounts required when the fair value of Eligible Assets is less than the aggregate principal loans balance as of the date;

(6)

interest due on permitted interest rate hedges if not paid in accordance with step (2) above;

(7)

optional prepayments to Lender during the investment period, which terminates October 1, 2012 (“Investment Period”) for temporary assets in accordance with Section 2.06(a) of the Loan Agreement;

(8)

remaining amounts to Partners after steps (1) through (7) of up to 8%;

(9)

optional prepayment up to the scheduled prepayment percentage or the outstanding loan balance; and (10)any final prepayment to Lender after satisfying steps (1) through (9).

The fair value of the UST loans, which qualify as financial instruments under ASC 825-10, approximates the carrying amounts presented in the accompanying Statements of Assets, Liabilities and Partners Capital as of December 31, 2012 and December 31, 2011.

As of December 31, 2012, collateral of $3,089,771,901, which includes $2,448,664,437 Eligible Assets and $641,107,464 cash and cash equivalents, was held by the Master Fund for borrowings from the UST Credit Facility.

As of December 31, 2011, collateral of $4,018,938,770, which includes $3,873,876,004 Eligible Assets and $145,062,766 cash and cash equivalents, was held by the Master Fund for borrowings from the UST Credit Facility.

The Master Fund made a Full Turn Election (“Full Turn Election”), which occurs when the Master Fund elects to borrow from the UST up to 100% of the aggregate amounts of drawn Master Fund capital commitments. In consideration for the borrowing, the Master Fund issued a warrant to the UST (in addition to the interest rate stipulated in the Loan Agreement), as evidenced by the issuance of a contingent promissory note. See Note 4 and Note 6 for further details on the UST warrant.

The Master Fund is subject to certain financial covenants such as the asset coverage test pursuant to the Loan Agreement. The Master Fund is required to maintain a minimum asset coverage ratio of 150% (as required for the Full Turn Election), which would require total assets (adjusted as appropriate) be at least 150% of the UST loan (including interest payable). As of December 31, 2012 and December 31, 2011, the Master Fund was in compliance with this covenant.

The Master Funds participation in the PPIP has certain risk factors as further described in Note 7.

4.	Partners Capital

Capital Commitments and Capital Contributions

Under the terms of the Master Fund Agreement, the General Partner admitted Limited Partners (the “Limited Partners” and collectively with the General Partner, “Partners”) to the Master Fund on

Wellington Management Legacy Securities PPIF Master Fund, LP

(a Delaware limited partnership)

Notes to Financial Statements (continued)

December 31, 2012 and December 31, 2011

(in United States Dollars)

October 1, 2009. In aggregate, a total of $2,298,985,495 in Partners capital commitments were accepted, including commitments of $324,387,000, $825,100,000, $1,149,487,000 and $11,495 from the Onshore Feeder, Offshore Feeder, the UST and the General Partner, respectively. As of December 31, 2012 and December 31, 2011, the Master Fund called and has received all capital commitments in cash contributions from the Partners.

Capital Allocations

For financial reporting and other purposes, income, gains, deductions, losses and credits of the Master Fund will generally be allocated among the Partners in a manner consistent with the distribution priorities described below. Accordingly, UST Management Fee has been allocated to UST and amortization of debt issuance costs and unrealized depreciation on UST Warrant has been allocated to the non-UST partners.

Capital Distributions

Distribution of investment proceeds are initially made to the Partners in proportion to each of their respective percentage interests in proportion to capital contributions. The Investment Manager had the discretion to retain capital for future investment opportunity during the Investment Period. Each Partners (other than the USTs) share of each distribution of the investment proceeds are to be divided between such Partners as follows:

(1)

Return of Capital: First, 100% to such Partner until the cumulative distributions to such Partner of investment proceeds equal such Partners capital contributions;

(2)

UST Warrant Proceeds Split: Thereafter, 97.5% to such Partner and 2.5% warrant percentage split to the UST. Pursuant to the Master Fund Agreement, the warrant percentage is contingent upon whether the borrowing is made with a Full Turn Election or Half Turn Election at the initial time of closing. The warrant percentage associated with the Full and Half Turn Elections are 2.5% and 1.5% respectively. The Master Fund has made a Full Turn Election, therefore the applicable warrant percentage is 2.5%; however the Master Fund does have the ability to revert to a Half Turn Election in the future. Escrow accounts were established for the deposit of such warrant percentage proceeds, and the proceeds are subject to clawback from the UST if the amount on deposit exceeds 2.5% of investment proceeds in excess of cumulative capital contributions to the Master Fund.

(3)

Temporary Investment Income: Each distribution of temporary investment income shall be divided among all Partners pro rata in proportion to their respective interests in the applicable temporary investments, as reasonably determined by the General Partner.

For the year ended December 31, 2012, the Master Fund did not make recallable distributions to the Partners. The Master Fund has made non-recallable distributions of Investment Proceeds in the amount of $80,809,223, $205,543,656, $284,053,905 and $2,864 to the Onshore Feeder, Offshore Feeder, UST and General Partner, respectively.

For the year ended December 31, 2011, the Master Fund did not make recallable distributions to the Partners. The Master Fund had made non-recallable distributions of Investment Proceeds in the amount of $20,777,563, $52,849,119, $71,327,707 and $736 to the Onshore Feeder, Offshore Feeder, UST and General Partner, respectively.

5.	Management Agreement

In consideration of the services rendered to the Master Fund by the Investment Manager pursuant to the Master Fund Agreement, the Master Fund pays a management fee to the General Partner with respect to the capital commitment currently in effect or at end of the given quarter of the UST (the “UST Management Fee”), payable quarterly in arrears, equal to 0.20% per annum of the capital commitment of the UST prior to the expiration or termination of the Investment Period and thereafter, 0.20% per annum of the lesser of (A) the USTs capital commitment to the Master Fund as of the last day of the period and (B) the UST ending capital as of the last day of the period. The UST Management Fee will be allocated to the capital account of the UST. The Private Investor Funds pay a separate management fee at the Onshore and Offshore Feeder level.

For the years ended December 31, 2012 and December 31, 2011, the Master Fund incurred UST Management Fees of $2,226,559 and $2,298,974, respectively. As of December 31, 2012 and December 31, 2011, $502,328 and $574,744 remained payable by the Master Fund, respectively.

6.	UST Warrant

As part of the financing arrangement between the Master Fund and the UST, the Master Fund issued a transferrable warrant to the UST (the “UST Warrant”). The terms of the warrant specify that each Partners (other than the USTs) share of each distribution of Investment Proceeds shall be divided between such Partner on the one hand and the UST on the other hand as follows: (i) Return of Capital: First, 100% to such Partner until the cumulative distributions to such Partner of Investment Proceeds equal such Partners Capital Contributions; (ii) UST Warrant Proceeds Split: Thereafter, 97.5% (the “Applicable Percentage”) to such Partner and 2.5% (the “Warrant Percentage”) to the UST. The applicable warrant payment will be distributed by the Master Fund to escrow accounts for the ultimate benefit of the UST following the return of 100% of each Partners capital contributions to the Master Fund. The UST Warrant has been accounted for as a freestanding derivative instrument, the current estimated fair value of which is reflected in “UST Warrant payable” on the accompanying Statements of Assets, Liabilities and Partners Capital. The change in fair value for the years ended December 31, 2012 and December 31, 2011 is recorded in “Net change in unrealized appreciation and (depreciation) on UST Warrant” on the accompanying Statements of Operations.

In connection with the closing of each Partners capital commitment, the Master Fund determined the value of the UST Warrant Payable. The recognition of UST Warrant Payable also resulted in the establishment of debt issuance costs in same amount. The debt issuance costs are amortized over the life of the Master Fund, which is expected to be eight years from initial closing. The amortization is recognized as interest expense in the Statements of Operations.

The following table summarizes how the Master Fund accounted for the effect of the UST Warrant on the results of operations and financial position of the Master Fund for the years ended December 31, 2012 and December 31, 2011:


Description	Fair Value		Change in Fair Value
2012 UST Warrant	$	11,185,834	$	688,581
2011 UST Warrant	$	11,874,415	$	781,077

As supplemental information to the US GAAP ending balances of Partners Capital presented in the Statements of Changes in Partners Capital, the following table represents what Partners Capital would be without the effect of the asset for debt issuance costs, and with the UST Warrant reflected at intrinsic, rather than fair value. Accordingly, the tables reflect the following as of December 31, 2012 and December 31, 2011:

•

amortized debt issuance cost and fair value of the UST warrant payable being written off, and

•

the amount due to the warrant holder being deducted from the capital accounts of the Partners, other than the UST, as if the Master Fund were to liquidate its tangible assets and liabilities at book value at year end (“intrinsic value”).

As the Master Fund was in a net gain position on this basis at December 31, 2012, the UST Warrant had an intrinsic value, and was reflected at $13,713,192 value in the table below.

7.	Risk Factors

The Master Funds investment portfolio is comprised entirely of CMBS and non-agency RMBS. These are securities whose payments depend (except for rights or other assets designed to assure the servicing or timely distribution of proceeds to holders of such securities) primarily on the cash flow from secured commercial or residential mortgage loans made to borrowers. Such loans are secured (on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances) by commercial or residential real estate, the proceeds of which are used to purchase and or to construct commercial or residential real estate. The Master Fund may also invest in stripped CMBS and non – agency RMBS (SCMBS + SRMBS). One type of SCMBS/SRMBS has one class receiving all of the interest from the mortgage assets (the interest-only or “IO” class), while the other class will receive all of the principle (the principal-only or “PO” class). Payments received for the IOs are included in “Interest income” on the Statements of Operations. The value of some mortgage-backed securities may be particularly sensitive to changes in prevailing interest rates. Early repayment of principal on some mortgage-related securities may expose the Master Fund to a lower rate of return upon reinvestment of principal. The value of these securities may fluctuate in response to the markets perception of the creditworthiness of the issuers. Additionally, although certain mortgage-related securities are supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. The investment portfolio is subject to various risks as described below:

Credit Risk

Credit-related risk on CMBS and non-agency RMBS securities arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the RMBS securities are issued. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including

(in United States Dollars)

general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrowers equity in the mortgaged property and the individual financial circumstances of the borrower.

Prepayment Risk

CMBS and non-agency RMBS securities are susceptible to prepayment risks. Except in the case of certain types of RMBS securities, the mortgage loans underlying RMBS securities generally do not contain prepayment penalties and a reduction in market interest rates may increase the likelihood of prepayments on the related RMBS securities, resulting in a reduction in yield to maturity for most holders of such securities. In the case of certain home equity loan securities and certain types of RMBS securities, even though the underlying mortgage loans can contain prepayment premiums, such prepayment premiums may not be sufficient to discourage borrowers from prepaying their mortgage loans in the event of a reduction in market interest rates, resulting in a reduction in the yield to maturity for holders of the related RMBS securities.

Interest Rate Risk

The rate of interest payable on certain CMBS and RMBS securities may be set or effectively capped at the weighted average net coupon of the underlying mortgage loans themselves, often referred to as an “available funds cap.” As a result of this cap, the return to the holder of such CMBS and RMBS securities is dependent on the relative timing and rate of delinquencies and prepayments of mortgage loans bearing a higher rate of interest. In general, early prepayments will have a greater negative impact on the yield to the holder of such CMBS and RMBS securities.

General Market Risk

The fair value of any particular CMBS and RMBS securities may be subject to substantial variation. The entire market or particular instruments traded on a market may decline even if earnings or other factors improve inasmuch as the prices of such instruments are subject to numerous economic, political, psychological and other factors that have little or no correlation to the performance of a particular instrument.

Swap Contracts Risk

The risks associated with swaps may exceed amounts recognized on the Statements of Assets, Liabilities and Partners Capital. The Master Fund may incur liquidity risk when it uses swaps because purchase and resale may be limited to a discrete number of dealers. The value of the swap will decrease commensurately should there be unfavorable changes in rates or market values. Entering into interest rate swaps involves varying degrees of risk, including the possibility that there is no liquid market for the contracts, the counterparty to the swap may default on its obligation to perform, and unfavorable changes in interest rates and market values may occur.

Concentration Risk

The Master Fund concentrates its investments in CMBS and RMBS securities, as such, the overall impact on the Master Fund as a result of adverse developments in the CMBS and RMBS market could be considerably greater than if the Master Fund did not concentrate its investments in CMBS and RMBS securities.

Counterparty Credit Risk

The Master Fund may be exposed to credit risks in the event that the contracting party to a transaction fails to perform or that an institution or other entity with which the Master Fund has unsettled or open transactions will default. In addition, the Master Fund incurs counterparty risk when it enters into any type of swaps, derivatives, other over-the counter transactions or non-U.S. securities with a bank or broker-dealer based on the risk of non-performance by the counterparty. Counterparty risk is partially managed through a number of risk mitigants including prudent counterparty selection and collateral agreements. The Master Fund enters into these contracts with counterparties who meet the suitability standards established by the Investment Adviser, to reduce risk from potential counterparty default.

Indemnifications

The Master Fund enters into contracts that contain a variety of indemnifications. The Master Funds maximum exposure under these arrangements is unknown. However, the Master Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

PPIP Risk

The PPIP is further subject to various political pressures and changes, and the UST or the United States government may change, suspend, or terminate the program at any time, which may be detrimental to the Investors.

Leverage Risk

The Master Fund utilized leverage as described in Note 3 as part of the Master Fund investment strategy. While leverage presents opportunities for increasing the total return on investments, it has the effect of potentially increasing losses as well. Accordingly, any event which adversely affects the value of an investment could be magnified to the extent leverage is utilized. The cumulative effect of the use of leverage with respect to any investments in a market that moves adversely to such investments could result in a substantial loss that would be greater than if the investment were not leveraged.
