Notes to Financial Statements

As of and for the Period from January 1, 2011 to June 30, 2011

(Unaudited)

Note 1—Organization

PNMAC Mortgage Opportunity Fund, LLC (the “Fund”) is a limited liability company organized under the laws of the state of Delaware. The Fund is registered under the Investment Company Act of 1940, as amended, as a closed-end, non-diversified management company. Shares of the Fund were issued solely in private placement transactions that did not involve any “public offering” within the meaning of Section 4(2) of the Securities Act of 1933, as amended (the “1933 Act”). Investments in the Fund may be made only by “accredited investors” within the meaning of Regulation D under the 1933 Act. The investment objective of the Fund is to achieve attractive total returns by capitalizing on dislocations in the mortgage market through opportunistic investments primarily in U.S. residential mortgages and related assets, instruments and entities.

The Fund is managed by PNMAC Capital Management, LLC (the “Investment Manager”). The Investment Manager is a registered investment adviser with the Securities and Exchange Commission (“SEC”).

The Fund invests substantially all of its assets in a limited partnership interest of PNMAC Mortgage Opportunity Fund, LP (the “Master Fund”), a limited partnership formed under the laws of the state of Delaware. The general partner of the Master Fund is PNMAC Opportunity Fund Associates, LLC (the “General Partner”), a Delaware limited liability company and a controlled subsidiary of Private National Mortgage Acceptance Company, LLC, both of which are affiliates of the Fund.

The Master Fund operates as a master fund in a master-feeder fund structure. The Master Fund acts as a central investment mechanism for the Fund and the General Partner. The General Partner has the exclusive right to conduct the operations of the Master Fund. The Fund held a 99.99% interest at June 30, 2011. The Fund is the sole limited partner in the Master Fund.

The Master Fund has the same investment objective as the Fund and conducts its operations through investments in PNMAC Mortgage Co., LLC, PNMAC Mortgage Co. Funding, LLC and PNMAC Mortgage Co (FI), LLC (collectively, the “Mortgage Investments”).

·	PNMAC Mortgage Co., LLC is a wholly owned limited liability company. PNMAC Mortgage Co., LLC acquires, holds and works-out distressed U.S. residential mortgages.

·	PNMAC Mortgage Co. Funding, LLC is a wholly owned limited liability company. PNMAC Mortgage Co. Funding, LLC acquires, holds and works out distressed U.S. residential mortgages, and owns mortgage-backed securities resulting from securitization of such mortgage loans.

PNMAC Mortgage Co (FI), LLC is an investment company that was formed to pool investor capital and take an interest in the proceeds of FNBN I, LLC (“FNBN”). FNBN is a limited liability company formed to own a pool of residential loans in partnership with the Federal Deposit Insurance Corporation (the “FDIC”). The pool of residential loans had an unpaid principal balance totaling $558 million at the inception of FNBN. The FDIC owns a substantial participation interest in the proceeds of the loans held by FNBN that depends on the amount of proceeds collected; the remaining share is owned by PNMAC Mortgage Co (FI), LLC.

As market conditions permit, PNMAC Mortgage Co., LLC may transfer the mortgage loans it owns to the Master Fund to be securitized for financing purposes or sale. The Master Fund may hold interests in pools of such securitized mortgages and invests directly in other mortgage-related investment securities.

PNMAC Mortgage Opportunity Fund, LLC

Notes to Financial Statements

As of and for the Period from January 1, 2011 to June 30, 2011

(Unaudited)

At June 30, 2011, the Master Fund owned 100% of PNMAC Mortgage Co., LLC, 69.3% of PNMAC Mortgage Co (FI), LLC, and 100% of PNMAC Mortgage Co. Funding, LLC.

The financial statements of the Master Fund, including the Schedule of Investments, are included elsewhere in this report and should be read with the Fund’s financial statements.

The Fund began operations on August 11, 2008 and will continue in existence through December 31, 2016, subject to three one-year extensions by the Investment Manager at its discretion, in accordance with the terms of the Limited Liability Company Agreement governing the Fund.

Note 2—Significant Accounting Policies

The Fund prepares its financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as codified in the Financial Accounting Standards Board’s Accounting Standards Codification (the “Codification”). Following are the significant accounting policies adopted by the Fund:

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, recognition of distribution income and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Fair Value

The Fund carries its investments at their estimated fair values with changes in fair value recognized in current period results of operations. The Fund applies the hierarchy described in the Fair Value Measurements and Disclosures topic of the Codification, which prioritizes the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active market for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable.

Each financial instrument’s level assignment within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement for that particular instrument. The three levels of the hierarchy are described below:

Level 1 – Quoted prices in active market for identical securities.

Level 2 – Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayments speeds, credit risk and others.

Level 3 – Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect The Fund’s own assumptions about the factors market participants would use in pricing an investment, and would be based on the best information available.

Changes in valuation techniques may also result in transfer in or out of an investment’s assigned level within the hierarchy.

PNMAC Mortgage Opportunity Fund, LLC

Notes to Financial Statements

As of and for the Period from January 1, 2011 to June 30, 2011

(Unaudited)

Most of The Fund’s assets are not actively traded and are considered illiquid. As a result, estimating the assets’ fair values is subject to uncertainties regarding the assumptions market participants would use to value the assets. Due to the inherent uncertainty of estimating fair values for assets that are not actively traded, the estimated fair value of the Fund’s investments may differ significantly from the value that may be realized if the Fund is liquidated and this difference could be material.

Investment in Master Fund

The Fund receives a proportionate limited partnership interest in the Master Fund equal to its relative contribution of capital to the Master Fund. The net increase or decrease in net assets resulting from operations includes the Fund’s proportionate share of the Master Fund’s income and losses (including net investment income and net realized and unrealized gains and losses on investments) arising from its investment in the Master Fund as reported by the General Partner of the Master Fund. Dividend income is recorded on the ex-dividend date or, using reasonable diligence, when known to the Fund. Securities transactions are recorded on the trade-date basis. Changes in fair value are recognized in current period results of operations.

Management's fair value estimates of investments held by the Master Fund are based on the expected proportionate share of the discounted cash flow projections of the assets and liabilities of these investments. The Master Fund’s Mortgage Investments are valued based on the proportionate share of the discounted cash flow projections of the assets and liabilities from these investments. These Mortgage Investments are valued based on the proportionate share of discounted cash-flow projections of the assets and liabilities of FNBN I, LLC, PNMAC Mortgage Co., LLC, and PNMAC Mortgage Co. Funding, LLC (“Mortgage Companies”) given that the loans or loan participation interest held by the Mortgage Companies represent substantially all of the net asset value held by these entities. Accordingly, fund management classifies the investment in the Master Fund as a “Level 3” financial statement item.

PNMAC Mortgage Co (FI), LLC’s operating agreement with the FDIC governing its investment in FNBN limits PNMAC Mortgage Co (FI), LLC’s ability to transfer any of its rights or interests in FNBN. PNMAC Mortgage Co (FI), LLC may only transfer all or any part of its interest or rights if (i) the transferee is a qualified transferee and (ii) it first obtains prior written consent of the FDIC. The contract specifies that the consent shall not be unreasonably withheld, delayed or conditioned, if the transferee is a qualified transferee.

Short-term Investment

The short-term investment, which represents money market funds, is valued at the number of shares multiplied by the value per share published by the manager of the money market fund on the valuation date. Fair value of such funds also include assessment of liquidity and credit risk, including lockout provisions, if any, related to these funds. Accordingly, fund management classifies the short-term investment as a “Level 1” financial statement item.

Expenses

The Fund is charged for those expenses that are directly attributable to it, such as, but not limited to, administration and custody fees. Expenses that are not directly attributable to the Fund are generally allocated among the Fund and other entities managed by the Investment Manager in proportion to their respective capital commitments. All general and administrative expenses are recognized on the accrual basis of accounting.

PNMAC Mortgage Opportunity Fund, LLC

Notes to Financial Statements

As of and for the Period from January 1, 2011 to June 30, 2011

(Unaudited)

Income Taxes

The Fund is treated as a separate taxable entity for Federal income tax purposes. The Fund’s policy is to comply with the provisions of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies and to distribute to shareholders all of its distributable net investment income and net realized gain on investments. Accordingly, no provision for Federal income or excise tax is necessary.

Management’s assessment of the requirement to provide for income taxes also includes an assessment of the liability arising from uncertain income tax positions. Management has concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken on the tax return for the fiscal year-end December 31, 2009, December 31, 2010, or expected to be taken on the tax returns for the fiscal year ended December 31, 2011. The Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. In developing its conclusion, management of the Fund has analyzed all tax years that are open for examination by the relevant income taxing authority. As of June 30, 2011, open Federal and state income tax years include the tax years ended December 31, 2008 through 2010. The Fund has no examinations in progress.

If applicable, the Fund will recognize interest accrued related to unrecognized tax benefits in “interest expense” and penalties in “other expenses” on the statement of operations.

Distributions to Shareholders

The Fund has outstanding Series A preferred shares. The preferred shares have an 8% cumulative dividend preference and a liquidation preference totaling $114,000. In the event of a liquidation of the Fund, the accumulated preferred dividends and the remaining face amount of the preferred shares will be distributed before any distributions are made to common shareholders.

Distributions to shareholders are recorded on the ex-dividend date. The character of distributions to shareholders made during the year may differ from their ultimate characterization for federal income tax purposes. The Fund will distribute substantially all of its net investment income and all of its capital gains to shareholders at least annually. The character of distributions made during the year from net investment income or net realized gains might differ from the characterization for federal income tax purposes due to differences in the recognition of income and expense items for financial statement and tax purposes.

Indemnifications

Under the Fund’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund may enter into contracts that provide general indemnification to other parties. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred, and may not occur. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2011-04 to the Fair Value Measurements topic of the Codification. ASU 2011-04 eliminates unnecessary wording differences between U.S. GAAP and International Financial Reporting Standards, expands the disclosure requirements of the Fair Value Measurements and Disclosure topic of the Codification for fair value measurements and makes other amendments, including:

PNMAC Mortgage Opportunity Fund, LLC

Notes to Financial Statements

As of and for the Period from January 1, 2011 to June 30, 2011

(Unaudited)

·	limiting the highest-and-best-use valuation-premise concepts only to measuring the fair value of nonfinancial assets;

permitting an exception to fair value measurement principles for financial assets and financial liabilities (and derivatives) with offsetting positions in market risks or counterparty credit risk when several criteria are met. When the criteria are met, an entity can measure the fair value of the net risk position;

clarifying that premiums or discounts that reflect size as a characteristic of the reporting entity’s holding rather than as a characteristic of the asset or liability (for example, a control premium when measuring the fair value of a controlling interest) are not permitted in a fair value measurement; and

·	prescribing a model for measuring the fair value of an instrument classified in shareholders’ equity; this model is consistent with the guidance on measuring the fair value of liabilities.

ASU 2011-04 expands the Fair Value Measurements topic’s disclosure requirements, particularly for fair value measurements categorized in Level 3 of the fair value hierarchy: (1) a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, (2) a description of the valuation processes in place (e.g., how the entity decides its valuation policies and procedures, as well as changes in its analyses of fair value measurements, from period to period), and (3) a narrative description of the sensitivity of the fair value to changes in unobservable inputs and interrelationships between those inputs.

ASU 2011-04 is applicable to the Master Fund for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 is not expected to have a material effect on the Master Fund’s financial statements.

Approval of Investment Management Agreement

On May 23-24, 2011, the Board of Directors of the Master Fund and the Fund (collectively, the “Funds”), including the “non-interested” Directors (the “Independent Directors”), met in person and voted to approve the continuance of the Investment Management Agreements (including the portion’s of the Master Fund’s partnership agreement referred to therein) with the Investment Manager for an additional year.

In considering whether to recommend approval of the Investment Management Agreements, the Independent Directors reviewed materials provided by the Investment Manager and counsel to the Independent Directors. The Independent Directors also met with senior personnel of the Investment Manager and discussed a number of topics affecting their determination, including the following.

(i) The nature, extent, and quality of services expected to be provided by the Investment Manager. The Independent Directors reviewed the services that the Investment Manager provided to the Funds since inception in August 2008 and are expected to continue to provide to the Funds. In addition, the Independent Directors considered the size, education, background, and experience of the Investment Manager’s staff, including the mortgage finance and capital markets experience of the Investment Manager’s senior management team. Lastly, the Independent Directors reviewed the Investment Manager’s ability to attract and retain quality and experienced personnel. The Independent Directors concluded that the scope of services provided since inception and expected to be provided by the Investment Manager to the Funds, and the experience and expertise of the personnel performing such services, was consistent with the nature, extent, and quality expected of an investment adviser of investment vehicles such as the Funds.

(ii) The investment performance of the Funds and the Investment Manager. The Independent Directors received information about the performance of the Funds and the Investment Manager in managing the Fund. The Directors also received performance information regarding the Funds compared to certain indexes, benchmarks, and/or registered and non-registered funds managed by other investment advisers that had somewhat comparable investment programs.

(iii) Cost of the services to be provided and profits to be realized by the Investment Manager and its affiliates from the relationship with the Funds. The Independent Directors considered the estimated cost of the services provided by the Investment Manager. As part of their analysis, the Independent Directors gave substantial consideration to the compensation payable to the Investment Manager. The Independent Directors noted that the compensation terms would remain the same. In reviewing the management compensation, the Independent Directors considered the management fees and operating expense ratios of other registered and non-registered funds managed by other investment advisers that had somewhat comparable investment programs. The Independent Directors also reviewed and took into account other relationships between the Funds and the Investment Manager and its related persons, including the shareholder servicing agreement between the Investment Manager and the Fund, the mortgage servicing agreements between the Master Fund and an affiliate of the Investment Manager, and a portfolio valuation agreement between the Fund and BlackRock, which has an investment in the Investment Manager’s parent company. The Independent Directors also considered the compensation charged by the Investment Manager to its other clients, and found such compensation arrangements were comparable. Finally, the Independent Directors took those other service agreements into account in the context of evaluating the profitability of the Investment Manager in respect of the overall relationship of the Investment Manager and its related persons to the Funds.

The Independent Directors concluded that the compensation that the Investment Manager would receive under the Investment Management Agreements was reasonable.

(iv) Economies of Scale. The Independent Directors also considered that possible economies of scale from future growth of the Funds were not relevant inasmuch as the Funds were closed to any new investment and had limited terms.

The Independent Directors had an opportunity to have Executive Session with counsel to the Independent Directors. During the course of their deliberations at the meetings on May 23-24, the Independent Directors thoroughly reviewed and evaluated the factors to be considered for approval of the Investment Management Agreements including, but not limited to: the expenses incurred in performance of services by the Investment Manager; the compensation to be received by the Investment Manager under the Investment Management Agreements; the fees charged by the Investment Manager’s peers; the past performance of the Investment Manager; and the range and quality of services provided by the Investment Manager.

The Independent Directors expressed satisfaction with the information provided at the meetings on May 23-24 and prior meetings, and acknowledged that they had received sufficient information to consider and approve the continuance of the Investment Management Agreements. No single factor was determinative to the decision of the Independent Directors. Rather, after weighing all of the reasons discussed above, the Independent Directors unanimously approved the continuance of the Investment Management Agreement.

Shareholder Meeting – May 26, 2011 – Final Results

The Fund held a Special Meeting of Shareholders on May 26, 2011 at the Fund's offices in Calabasas, California. At that meeting, common shareholders approved amendments to the "catchup" provisions of the investment management agreements of the Fund and of its portfolio partnership, the Master Fund.

PNMAC Mortgage Opportunity Fund, LP (the “Master Fund”) is a limited liability partnership organized under the laws of the state of Delaware. The Master Fund is registered under the Investment Company Act of 1940, as amended. Interests in the Master Fund were issued solely in private placement transactions that do not involve any “public offering” within the meaning of Section 4(2) of the Securities Act of 1933, as amended. The investment objective of the Master Fund is to achieve attractive total returns by capitalizing on dislocations in the mortgage market through opportunistic investments primarily in U.S. residential mortgages and related assets, instruments, and entities.

The Master Fund is managed by PNMAC Capital Management, LLC (the “Investment Manager”). The Investment Manager is a registered investment adviser with the Securities and Exchange Commission (“SEC”). The general partner of the Master Fund is PNMAC Opportunity Fund Associates, LLC (the “General Partner”), a Delaware limited liability company. Both the Investment Manager and General Partner are controlled subsidiaries of Private National Mortgage Acceptance Company, LLC.

The Master Fund operates as a master fund in a master-feeder fund structure. The Master Fund acts as a central investment mechanism for (i) PNMAC Mortgage Opportunity Fund, LLC (the “Fund” or “Limited Partner”) and (ii) the General Partner. The Fund owned 99.99% of the Master Fund at June 30, 2011 and is the sole limited partner. The General Partner has the exclusive right to conduct the operations of the Master Fund.

The Master Fund conducts its operations through investments in mortgage-backed securities, PNMAC Mortgage Co., LLC, PNMAC Mortgage Co. Funding, LLC and PNMAC Mortgage Co (FI), LLC (collectively, the “Mortgage Investments”).

·	PNMAC Mortgage Co., LLC is a wholly owned limited liability company. PNMAC Mortgage Co., LLC acquires, holds and works out distressed U.S. residential mortgages.

·	PNMAC Mortgage Co. Funding, LLC is a wholly owned limited liability company. PNMAC Mortgage Co. Funding, LLC acquires, holds and works out distressed U.S. residential mortgages, and owns mortgage-backed securities resulting from securitization of such mortgage loans.

Note 2—Significant Accounting Policies

The Master Fund prepares its financial statements in accordance with accounting principles generally accepted in The United States of America (“U.S. GAAP”). The Master Fund reports its investments in the Mortgage Investments in accordance with the Special Rules of General Application to Registered Investment Companies

topic of the Codification as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (the “Codification”) and the AICPA Audit and Accounting Guide: Investment Companies. These rules do not permit the Master Fund to consolidate its ownership interest in such investments. Following are the significant accounting policies adopted by the Master Fund:

Use of Estimates

Fair Value

Level 1 – Quoted prices in active market for identical securities.

Changes in valuation techniques may also result in transfer in or out of an investment’s assigned level within the hierarchy.

Most of the Fund’s assets are not actively traded and are considered illiquid. As a result, estimating the assets’ fair values is subject to uncertainties regarding the assumptions market participants would use to value the assets. Due to the inherent uncertainty of estimating fair values for assets that are not actively traded, the estimated fair value of the Fund’s investments may differ significantly from the value that may be realized if the Fund is liquidated and this difference could be material.

Short-term Investment

Short-term investment represents an investment in money market funds are valued at the number of shares multiplied by the value per share published by the manager of the money market funds on the valuation date. Accordingly fund manager classifies the short-term investment as a “Level 1” financial statement item. Fair value of such funds also include assessment of liquidity and credit risk, including lockout provisions, if any, related to these funds.

Mortgage-Backed Securities

Mortgage-backed securities transactions are recorded on the trade-date basis. Changes in fair value are recognized in current period results of operations. Mortgage-backed securities are valued using broker indications of value. The estimates of value are evaluated by the Investment Manager’s Capital Markets staff and are reviewed and approved by its senior management Valuation Committee. The Investment Manager’s review is for the purpose of evaluating the reasonableness of the brokers’ valuations. The Investment Manager’s evaluations of broker indications of value may result in the broker modifying its indications of value. However, the Investment Manager does not intend to independently adjust the brokers’ indications of value. Accordingly, Fund management classifies the fair value measurements it develops for Mortgage-Backed Securities as “Level 3” financial statement items.

Mortgage Investments

Mortgage Investments have been estimated by management in the absence of readily determinable fair values. These Mortgage Investments are valued based on the proportionate share of the discounted cash-flow projections of the underlying assets and liabilities of FNBN I, LLC, PNMAC Mortgage Co., LLC, and PNMAC Mortgage Co. Funding, LLC (“Mortgage Companies”) given that the loans or loan participation interest held by the Mortgage Companies, including related concentration risks, represent substantially all of the net asset value held by these entities.

The Mortgage Companies value their investments in mortgage loans based on whether they are committed to be sold. Loans which are committed to be sold are valued at their quoted market price or market price equivalent. Mortgage loans that are not committed to be sold are recorded at their estimated fair value, which is approximated using a discounted cash flow valuation model. Inputs to the model include current interest rates, loan amount, payment status, property type, forecasts of future interest rates, home prices, prepayment speeds, defaults and loss severities. Accordingly, the Fund’s Manager classifies the Mortgage Investments as “Level 3” financial statement items. The estimates of value are evaluated by our Manager’s Capital Markets staff and are reviewed and approved by its senior management Valuation Committee. Changes in the estimated fair value of mortgage loans are recognized in current period results of operations. All changes in fair value, including changes arising from the passage of time, are recognized as a component of change in fair value of investments.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase represent the discounted value of the borrowings using the rate required to finance such borrowings as of period end. Accordingly, the Fund’s Manager has classified securities sold under agreements to repurchase as “Level 3” financial instruments.

Interest Income

Interest income is accrued as earned. Unamortized premiums and unearned discounts are amortized and accrued to interest income as an adjustment of the instruments’ yields using the interest method. Yields are estimated using market prepayment expectations for similar assets.

Dividend Income

Dividend income is recorded on the ex-dividend date or, using reasonable diligence, when known to the Master Fund.

Expenses

The Master Fund is charged for those expenses that are directly attributable to it, such as, but not limited to, advisory and custody fees. Expenses that are not directly attributable to the Master Fund are generally allocated among the entities in proportion to their respective capital commitments. All general and administrative expenses are recognized on the accrual basis of accounting.

Income Taxes

The Master Fund has elected to be treated as a partnership for federal income tax purposes. Each partner is responsible for the tax liability or benefit relating to such partner’s distributive share of taxable income or loss. Accordingly, no provision for federal income taxes is reflected in the accompanying financial statements.

Management’s assessment of the requirement to provide for income taxes also includes an assessment of the liability arising from uncertain income tax positions. Management has concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken on the tax return for the fiscal year ended December 31, 2010 or expected to be taken on the tax returns for the fiscal year ended December 31, 2011. The Master Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. In developing its conclusion, management of the Master Fund has analyzed all tax years that are open for examination by the relevant income taxing authority. As of June 30, 2011, open Federal and state income tax years include the tax year ended December 31, 2010 through 2008. The Master Fund has no examination in progress.

If applicable, the Master Fund will recognize interest accrued related to unrecognized tax benefits in “interest expense” and penalties in “other expenses” on the statement of operations.

No distributions will be made by the Master Fund to cover any taxes due on Limited Partners’ investments in the Master Fund. Investors may not redeem capital from the Master Fund, and they must have other sources of capital available to them in order to pay such taxes.

Partners’ Capital

Net profits or net losses of the Master Fund for each month are allocated to the capital accounts of partners as of the last day of each month in accordance with partners’ respective investment ownership percentages of the Master Fund. Net profits or net losses are measured as the net change in the value of the partners’ capital of the Master Fund during the fiscal period, before giving effect to any repurchases of interest in the Master Fund, and excluding the amount of any items to be allocated to the capital accounts of the partners of the Master Fund, other than in accordance with the partners’ respective investment ownership percentages.

Capital Distributions and Carried Interest

Distributions are made in accordance with the following distribution priorities but may be recalled by the Master Fund for purposes of making new investments until December 31, 2011. Following is a summary of capital distribution priorities:

Notes to Financial Statements

As of and For the Period Ended June 30, 2011

(Unaudited)

1.	First, 100% to such Limited Partner until such Limited Partner has received 100% of such Limited Partner’s capital contributions (irrespective of whether such capital contributions were used to make investment, pay management fees and expenses or any other purpose);

2.	Second, 100% to such Limited Partner, until such Limited Partner has received a preferred return on the amounts described in (1) above calculated at a rate of 8%, compounded annually;

3.	Third, 100% to the General Partner until the General Partner has received an amount equal to 20% of the profits distributed to the Limited Partner pursuant to (2) above; and

4.	Thereafter, (i) 80% to such Limited Partner and (ii) 20% to the General Partner (the “Carried Interest”).

The Carried Interest is allocated (and subsequently distributed) by the Master Fund to the General Partner as allocable shares of the Master Fund’s gains.

Indemnifications

Under the Master Fund’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Master Fund. In addition, in the normal course of business, the Master Fund may enter into contracts that provide general indemnification to other parties. The Master Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Master Fund that have not yet occurred, and may not occur. However, the Master Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Recent Accounting Pronouncements

·	limiting the highest-and-best-use valuation-premise concepts only to measuring the fair value of nonfinancial assets;

·	prescribing a model for measuring the fair value of an instrument classified in shareholders’ equity; this model is consistent with the guidance on measuring the fair value of liabilities.

Note 11—Risk Factors

The Master Fund’s investment activities expose it to the various types of risk, which are associated with the financial instruments and markets in which it invests.

Investments in mortgage-backed securities and mortgage loans have exposure to certain degrees of risk, including interest rate, market risk, and the potential non-payment of principal and interest, including default or bankruptcy of the issuer or the intermediary in the case of a participation. Mortgage-backed securities and mortgage loans are subject to prepayment risk, which will affect the maturity of such investments.

Investments in real estate acquired in settlement of loans are subject to various risk factors. Generally, real estate investments could be adversely affected by a recession or general economic downturn where the properties are located as well as the availability of similar properties in the immediate area. Real estate investment performance is also subject to the success that a particular property manager has in managing the property.

The Master Fund is indirectly subject to interest rate risk. Interest rate risk is the risk that investment in loans held by the Mortgage Investments will decline in value because of changes in market interest rates. Investments in mortgage loans with long-term maturities may experience significant price declines if long-term interest rates increase.

Market risk represents the potential loss in value of financial instruments caused by movements in market factors including, but not limited to, market liquidity, investor sentiment, interest and foreign exchange rates. The Master Fund’s portfolio includes certain investments that are generally illiquid and have a greater amount of market risk than more liquid investments. These investments may trade in limited markets or have restrictions on resale or transfer and may not be able to be liquidated on demand if needed. The value assigned to these investments may differ significantly from the values that would have been used had a ready market existed and such differences could be material to the financial statements.

Adverse changes in economic conditions are more likely to lead to a weakened capacity of borrowers to make principal payments and interest payments. An economic downturn could severely affect the ability of highly leveraged borrowers to service their debt obligations or to repay their obligations. Under adverse market or economic conditions, the secondary market could contract further as well, increasing the illiquid nature of the loans. As a result, the Mortgage Investments could find it more difficult to sell loans or may be able to sell only at prices lower than if such investments were widely traded.

An investment in the Master Fund is subject to investment risk, including the possible loss of the entire principal invested. An investment in the Master Fund represents an indirect investment in the loans held by the Mortgage Companies. The value, like other market investments, may move up or down, sometimes rapidly and unpredictably. An investment in the Master Fund at any point in time may be worth less than the original investment. Investment values can fluctuate for several reasons including the general condition of the mortgage market or when political or economic events affecting the issuers occur.

As part of its investment strategy, the Master Fund may utilize borrowings. Master Fund investments may also use borrowings in the ordinary course of their operations. The use of borrowings may materially affect the operations of the Master Fund or its investment and thus its ultimate value. Financing may not always be available on acceptable terms, in the necessary amounts, or for the period needed. This could have a material negative impact on the performance of the Master Fund.

The Master Fund clears substantially all of its investment purchases and sales and maintains substantially all of its investments and cash positions at U.S. Bank, N.A. Credit risk is measured by the loss the Master Fund would record if U.S. Bank, N.A. failed to perform pursuant to terms of their obligations.

Due to the nature of the master fund/feeder fund structure, the Master Fund could be materially affected by subscription or redemption activity.

In light of financial market events that occurred in 2009 and 2008 and the United States government’s involvement in supporting the financial markets, it is reasonably possible that the investment management industry will be subject to future regulation. The impact of potential regulation may have a negative impact on the ability to unwind the investments of the Master Fund and Mortgage Investments, but such impact is not quantifiable.

Note 12—Subsequent Events

Management has evaluated all events or transactions through August 31, 2011, the date the Master Fund issued these financial statements. During this period, the Master Fund received dividends from a related party in the amount of $892,138, and made distributions to its limited partners of $1,092,301.
