Partners Group Private Equity (Institutional), LLC

(a Delaware Limited Liability Company)

Notes to Financial Statements – September 30, 2012 (unaudited)

1. Organization

Partners Group Private Equity (Institutional), LLC (the “Fund”) was organized as a limited liability company under the laws of the State of Delaware on August 4, 2008 and commenced operations on July 1, 2009. The Fund is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a closed-end, non-diversified management investment company. The objective of the Fund is to seek attractive long-term capital appreciation by investing in a diversified portfolio of private equity investments. To achieve its objective, the Fund will invest substantially all of its assets in limited liability company interests (“Interests”) in Partners Group Private Equity (Master Fund), LLC (the “Master Fund”), a limited liability company organized under the laws of the State of Delaware, which is also registered under the 1940 Act. The Master Fund is managed by Partners Group (USA) Inc. (the “Adviser”), an investment adviser registered under the Investment Advisers Act of 1940, as amended. A Board of Managers (the “Board”) has overall responsibility for the management and supervision of the business operations of the Fund. To the fullest extent permitted by applicable law, the Board may delegate any of its rights, powers and authority to, among others, the officers of the Fund, any committee of the Board, or the Adviser. Units of limited liability company interests (“Units”) in the Fund are offered only to investors (“Members”) that represent that they are an “accredited investor” within the meaning of Rule 501 under the Securities Act of 1933, as amended, and a “qualified client” within the meaning of Rule 205-3 under the Investment Advisers Act of 1940, as amended. The Fund’s financial statements should be read in conjunction with the Master Fund’s financial statements, which are included as Appendix I.

At September 30, 2012, the Fund owned 7.26% of the Interests in the Master Fund.

2. Significant Accounting Policies

The following is a summary of significant accounting and reporting policies used in preparing the financial statements.

a. Basis of Accounting

The Fund’s accounting and reporting policies conform with generally accepted accounting principles within the United States (“U.S. GAAP”).

b. Valuation of Investments

The Fund values its investment in the Master Fund at the net asset value of the Interests owned by the Fund in the Master Fund as such net asset value is determined by the Fund. Investments held by the Master Fund include direct, secondary and primary private equity investments (collectively, “Private Equity Investments”). The Master Fund values interests in the Private Equity Investments at fair value in accordance with procedures established by the Board and the Board of Managers of the Master Fund. Private Equity Investments are subject to the terms of their respective Private Equity Investments’ offering documents. Valuations of Private Equity Investments are subject to estimates and are net of management and performance incentive fees or allocations that may be payable pursuant to such offering documents.

c. Allocations from the Master Fund

In accordance with U.S. GAAP, the Fund records its allocated portion of income, expense, realized gains and losses and unrealized appreciation and depreciation allocated from the Master Fund.

d. Fund Level Income and Expenses

Interest income on any cash or cash equivalents held by the Fund is recognized on an accrual basis. Expenses that are specifically attributed to the Fund are accrued and charged to the Fund. Because the Fund bears its proportionate share of the management fees of the Master Fund, the Fund pays no direct management fee to the Adviser. Income and expenses are recorded on an accrual basis.

e. Expense Limitation Agreement

Effective February 1, 2010, the Adviser has entered into an expense limitation agreement (the “Expense Limitation Agreement”) with the Fund. The Adviser has agreed to waive fees that it would otherwise be paid, and/or to assume expenses of the Fund (a “Waiver”), if required to ensure the Total Annual Expenses (excluding taxes, interest, brokerage commissions, certain transaction-related expenses, extraordinary expenses, the Incentive Allocation (as defined below) and any acquired fund fees and expenses) do not exceed 2.30%, on an annualized basis (the “Expense Limit”). For a period not to exceed three years from the date on which a Waiver is made, the Adviser may recoup amounts waived or assumed, provided it is able to effect such recoupment and remain within the Expense Limit. The Expense Limitation Agreement may be terminated by the Adviser or the Fund upon thirty days’ written notice to the other party. As of September 30, 2012, there were no amounts waived or assumed that are subject for recoupment by Adviser.

Notes to Financial Statements – September 30, 2012 (unaudited) (continued)

2. Significant Accounting Policies (continued)

f. Tax Basis Reporting

Because the Master Fund invests primarily in investments that are treated as partnerships for U.S. federal income tax purposes, the tax character of the Fund’s allocated earnings depends on the tax filings of the Private Equity Investments. Accordingly, the tax bases of these allocated earnings and the related balances are not available as of the reporting date.

g. Income Taxes

For U.S. federal income tax purposes, the Fund is treated as a partnership, and each Member in the Fund is treated as the owner of its allocated share of the net assets, income, expenses, and the realized and unrealized gains (losses) of the Fund. Accordingly, no federal, state or local income taxes are paid by the Fund on the income or gains of the Fund since the Members are individually liable for the taxes on their allocated share of such income or gains of the Fund.

The Fund has adopted the authoritative guidance on accounting for and disclosure of uncertainty in tax positions. The Financial Accounting Standards Board (“FASB”) issued Accounting for Uncertainty in Income Taxes, which requires the Adviser to determine whether a tax position of the Fund is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority.

The Fund files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Fund is subject to examination by federal, state, local and foreign jurisdictions, where applicable. As of September 30, 2012, the tax years from the year 2010 forward remain subject to examination by the major tax jurisdictions under the statute of limitations.

h. Cash and cash equivalents

Pending investment in the Master Fund, the Fund holds cash and cash equivalents including amounts held in interest bearing deposit accounts.

At times, such amounts may exceed federally insured limits. The Fund has not experienced any losses in such accounts and does not believe that it is exposed to any significant credit risk on such accounts.

i. 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 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 Members’ capital from operations during the reporting period. Actual results can differ from those estimates.

j. Recently Issued Accounting Pronouncements

In December 2011, FASB issued Accounting Standards Update (“ASU”) No. 2011-11 related to disclosures about offsetting assets and liabilities. The amendments in this ASU require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The ASU is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance requires retrospective application for all comparative periods presented. Management is currently evaluating the impact ASU No. 2011-11 will have on the financial statement disclosures.

Partners Group Private Equity (Institutional), LLC

(a Delaware Limited Liability Company)

Notes to Financial Statements – September 30, 2012 (unaudited) (continued)

3. Fair Value Measurements

The Fund records its investment in the Master Fund at the net asset value of the Interests owned by the Fund in the Master Fund. The Interests in the Master Fund, in which the Fund invests, are considered a Level 3 security as defined under fair valuation accounting standards. The Master Fund’s disclosure with respect to investments held by the Master Fund under the three-tier hierarchy is discussed in the Notes to the Master Fund’s financial statements.

4. Allocation of Members’ Capital

Net profits or net losses of the Fund for each Allocation Period (as defined below) are allocated among and credited to or debited against the capital accounts of the Members. Each Allocation Period begins on the day after the last day of the preceding Allocation Period and ends at the close of business on the first to occur thereafter of: (1) the last day of a calendar month, (2) the last day of a taxable year, (3) the day preceding a day on which interests are purchased, (4) a day on which Units are repurchased by the Fund pursuant to tenders of Units by Members, or (5) a day on which any amount is credited to or debited from the capital account of any Member other than an amount to be credited to or debited from the capital accounts of all Members in accordance with their respective investment percentages.

The Fund maintains a separate capital account on its books for each Member. As of any date, the capital account of a Member shall be equal to the net asset value per Unit as of such date, multiplied by the number of Units held by such Member. Any amounts charged or debited against a Member’s capital account under the Fund’s ability to allocate special items, and to accrue reserves, other than among all Members in accordance with the number of Units held by each Member, shall be treated as a partial repurchase of such Member’s Units for no additional consideration as of the date on which the Board determines such charge or debit is required to be made, and such Member’s Units shall be reduced thereby as appropriately determined by the Fund. Any amounts credited to a Member’s capital account under the Fund’s ability to allocate special items and to accrue reserves, other than among all Members in accordance with the number of Units held by each such Member, shall be treated as an issuance of additional Units to such Member for no additional consideration as of the date on which the Board determines such credit is required to be made, and such Member’s Units shall be increased thereby as appropriately determined by the Fund. As of September 30, 2012, there have been no special items or accrued receivables allocated to Members’ capital accounts.

5. Subscriptions and Repurchase of Members’ Interests

Units are generally offered for purchase as of the first day of each calendar month, but may be offered more or less frequently as determined by the Board in its sole discretion.

The Board may, from time to time and in its sole discretion, cause the Fund to repurchase Units from Members pursuant to written tenders by Members at such times and on such terms and conditions as established by the Board. In determining whether the Fund should offer to repurchase Units, the Board considers whether the Master Fund is making a contemporaneous repurchase offer for interests in the Master Fund, as well as a variety of other operational, business and economic factors. The Adviser anticipates recommending to the Master Fund’s Board of Managers that, under normal circumstances, the Master Fund conduct repurchase offers of no more than 5% of the Master Fund’s net assets quarterly on or about each January 1^st, April 1^st, July 1^st and October 1^st. It is anticipated that the Fund will generally conduct repurchase offers contemporaneously with repurchase offers conducted by the Master Fund. A 2.00% early repurchase fee will be charged by the Fund with respect to any repurchase of Units from a Member at any time prior to the day immediately preceding the one-year anniversary of the Member’s purchase of such Units.

6. Related Party Transactions and Other

An incentive allocation (“Incentive Allocation”) is calculated at the Master Fund level and allocated to the Fund based on the Fund’s ownership interest in the Master Fund. The Incentive Allocation is equal to 10% of the excess, if any, of (i) the allocable share of the net profits of the Master Fund for the relevant period of each member of the Master Fund, including the Fund, over (ii) the then balance, if any, of that Member’s Loss Recovery Account (as defined below) will be debited from such Member’s capital account and credited to a capital account of the Adviser (or, to the extent permitted by applicable law, of an affiliate of the Adviser) in the Master Fund (the “Incentive Allocation Account”). The Incentive Allocation Account is maintained solely for the purpose of allocating the Incentive Allocation.

Partners Group Private Equity (Institutional), LLC

(a Delaware Limited Liability Company)

Notes to Financial Statements – September 30, 2012 (unaudited) (continued)

6. Related Party Transactions and Other (continued)

The Master Fund maintains a memorandum account for each member of the Master Fund, including the Fund (each, a “Loss Recovery Account”). Each member’s Loss Recovery Account has an initial balance of zero and is (i) increased upon the close of each Allocation Period of the Master Fund by the amount of the relevant member’s allocable share of the net losses of the Master Fund for the Allocation Period, and (ii) decreased (but not below zero) upon the close of such Allocation Period by the amount of such member’s allocable share of the net profits of the Master Fund for the Allocation Period. The Incentive Allocation is calculated, charged to each member of the Master Fund and credited to the Incentive Allocation Account as of the end of each Allocation Period. The Allocation Period with respect to a member whose interest in the Master Fund is repurchased or is transferred in part is treated as ending only for the portion of the interest so repurchased or transferred. In addition, only the net profits of the Master Fund, if any, and the balance of the Loss Recovery Account attributable to the portion of the interest being repurchased or transferred (based on the member’s capital account amount being so repurchased or transferred) is taken into account in determining the Incentive Allocation for the Allocation Period then ending. The member’s Loss Recovery Account is not adjusted for such member’s allocable share of the net losses of the Master Fund, if any, for the Allocation Period then ending that are attributable to the portion of the interest so repurchased or transferred. For the six month period ended September 30, 2012, an Incentive Allocation of $191,247 was credited to the Incentive Allocation Account from the Fund.

At September 30, 2012, the Adviser owned $18,041,227 of the Fund (48.55% of Members’ Equity). A portion of the Fund’s net profits and losses, including the Incentive Allocation, is credited to or debited from Adviser’s capital account in accordance with Adviser’s respective investment percentage.

UMB Bank, N.A. (the “Custodian”) serves as custodian of the Fund’s cash balances and provides custodial services for the Fund. UMB Fund Services, Inc. (the “Administrator”) serves as administrator and accounting agent to the Fund and provides certain accounting, record keeping and investor related services. For these services the Custodian and the Administrator collectively receive a fixed monthly fee, based upon average net assets, and a monthly fee based on the number of Member accounts as well as reasonable out of pocket expenses. For the six month period ended September 30, 2012, the Fund paid $23,772 in administration and accounting fees.

7. Risk Factors

An investment in the Fund involves significant risks that should be carefully considered prior to investment and should only be considered by persons financially able to maintain their investment and who can afford a loss of a substantial part or all of such investment. The Master Fund invests substantially all of its available capital in Private Equity Investments. These investments are generally restricted securities that are subject to substantial holding periods and are not traded in public markets, so that the Master Fund may not be able to resell some of its holdings for extended periods, which may be several years. No guarantee or representation is made that the investment objective will be met.

A further discussion of the risks associated with an investment in the Fund is provided in the Master Fund’s Financial Statements, the Confidential Private Placement Memorandum and Statement of Additional Information.

8. Indemnification

In the normal course of business, the Fund enters into contracts that provide general indemnification. The Fund’s maximum exposure under these agreements is dependent on future claims that may be made against the Fund under such agreements, and therefore, cannot be established; however, based on experience, the risk of loss from such claims is considered remote.

9. Subsequent Events

Management has evaluated the impact of all subsequent events on the Fund through November 29, 2012, the date the financial statements were issued, and has determined that the following subsequent events require disclosure in the financial statements. Effective October 1, 2012 and November 1, 2012, there were additional capital contributions to the Fund in the amounts of $1,690,000 and $2,090,000, respectively. In addition, the Fund received, pending acceptance, tender requests in the amount of $2,198,577, which will be effective as of December 31, 2012.

The Fund changed its net asset value per Unit such that Members of record as of September 30, 2012 received, effective October 1, 2012, one hundred Units for every one Unit held. This resulted in an increase in Units outstanding from 27,622 to 2,762,192, and a decrease in net asset value per unit from $1,345.28 to $13.45.

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Financial Statements – September 30, 2012 (unaudited)

1. Organization

Partners Group Private Equity (Master Fund), LLC (the “Master Fund”) was organized as a limited liability company under the laws of the State of Delaware on August 4, 2008 and commenced operations on July 1, 2009. The Master Fund is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a closed-end, non-diversified management investment company. The Master Fund is managed by Partners Group (USA) Inc. (the “Adviser”), an investment adviser registered under the Investment Advisers Act of 1940, as amended. A Board of Managers (the “Board”) has overall responsibility for the management and supervision of the business operations of the Master Fund. To the fullest extent permitted by applicable law, the Board may delegate any of its rights, powers and authority to, among others, the officers of the Master Fund, any committee of the Board, or the Adviser. The objective of the Master Fund is to seek attractive long-term capital appreciation by investing in a diversified portfolio of private equity investments.

The Master Fund is a master investment portfolio in a master-feeder structure. Partners Group Private Equity, LLC, Partners Group Private Equity (Institutional), LLC, Partners Group Private Equity (TEI), LLC, and Partners Group Private Equity (Institutional TEI), LLC, (collectively “the Feeder Funds”) invest substantially all of their assets, directly or indirectly, in the limited liability company interests (“Interests”) of the Master Fund and become members of the Master Fund (“Members”).

2. Significant Accounting Policies

 The following is a summary of significant accounting and reporting policies used in preparing the financial statements.

a. Basis of Accounting

The Master Fund’s accounting and reporting policies conform with generally accepted accounting principles within the United States (“U.S. GAAP”).

b. Valuation of Investments

Investments held by the Master Fund include direct equity and debt investments (“Direct Investments”) and secondary and primary private equity investments (“Private Equity Fund Investments”) (collectively, “Private Equity Investments”).

Direct Investments

In assessing the fair value of non-traded Direct Investments, the Master Fund uses a variety of methods such as the time of last financing, earnings and multiple analysis, discounted cash flow and third party valuation, and makes assumptions that are based on market conditions existing at each end of the reporting period.  Quoted market prices or dealer quotes for specific similar instruments are used for long-term debt where appropriate.  Other techniques, such as option pricing models and estimated discounted value of future cash flows, are used to determine fair value for the remaining financial instruments.

Private Equity Fund Investments

The Master Fund values Private Equity Fund Investments at fair value, which ordinarily is based on the value determined by their respective investment managers, in accordance with procedures established by the Board. Private Equity Fund Investments are subject to the terms of their respective offering documents. Valuations of Private Equity Fund Investments are subject to estimates and are net of management and performance incentive fees or allocations that may be payable pursuant to such offering documents. If the Adviser determines that the most recent value reported by a Private Equity Investment does not represent fair value or if a Private Equity Investment fails to report a value to the Master Fund, a fair value determination is made under procedures established by and under the general supervision of the Board. Because of the inherent uncertainty in valuation, the estimated values may differ from the values that would have been used had a ready market for the securities existed, and the differences could be material.

The Master Fund has adopted the authoritative guidance under U.S. GAAP for estimating the fair value of investments in investment companies. Accordingly, in circumstances in which net asset value of an investment in an investment company is not determinative of fair value or the net asset value of the investment is determined using accounting guidance other than U.S. GAAP, the Master Fund estimates the fair value of such investment using the net asset value of the investment (or its equivalent) without further adjustment.

2. Significant Accounting Policies (continued)

b. Valuation of Investments (continued)

The following is a summary of the inputs used in valuing the Master Fund's Private Equity Investments at fair value.  The inputs or methodology used for valuing the Master Fund's Private Equity Investments are not necessarily an indication of the risk associated with investing in those investments.  The Master Fund's valuation procedures require evaluation of all relevant factors available at the time the Master Fund values its investments. 

Daily Traded Investments

The Master Fund values investments traded (1) on one or more of the U.S. national securities exchanges or the OTC Bulletin Board at their last sales price, and (2) on NASDAQ at the NASDAQ Official Closing Price, at the close of trading on the exchanges or markets where such securities are traded for the business day as of the relevant determination date. If no sale or official closing price of particular securities are reported on a particular day, the securities will be valued at the closing bid price for securities held long, or the closing ask price for securities held short, or if a closing bid or ask price, as applicable, is not available, at either the exchange or system-defined closing price on the exchange or system in which such securities are principally traded. Securities traded on a foreign securities exchange generally will be valued at their closing prices on the exchange where such securities are primarily traded and translated into U.S. dollars at the current exchange rate provided by a recognized pricing service.

Investments for which no prices are obtained under the foregoing procedures, including those for which a pricing service supplies no exchange quotation or a quotation that is believed by the Adviser not to reflect the market value, will be valued at the bid price, in the case of securities held long, or the ask price, in the case of securities held short, supplied by one or more dealers making a market in those securities or one or more brokers. High quality investment grade debt securities (e.g., treasuries, commercial paper, etc.) with a remaining maturity of 60 days or less are valued by the Adviser at amortized cost, which the Board has determined to approximate fair value.

c. Cash and Cash Equivalents

Pending investment in Private Equity Investments and in order to maintain liquidity, the Master Fund holds cash, including amounts held in foreign currency and short-term interest bearing deposit accounts. At times, such amounts may exceed federally insured limits.

The Master Fund has not experienced any losses in such accounts and does not believe that it is exposed to any significant credit risk on such accounts.

d. Foreign Currency Translation

The books and records of the Master Fund are maintained in U.S. Dollars. Generally, assets and liabilities denominated in non-U.S. currencies are translated into U.S. Dollar equivalents using valuation date exchange rates, while purchases, realized gains and losses, income and expenses are translated at the transaction date exchange rates. As of September 30, 2012 the Master Fund has thirty-nine investments denominated in Euros, five investments denominated in Australian Dollars, four investments denominated in British Pounds, two investments denominated in Swedish Kronor, one investment denominated in Norwegian Kronor, and one investment denominated in Hong Kong Dollars. The Master Fund does not isolate the portion of the results of operations due to fluctuations in foreign exchange rates from changes in fair values of the investments during the period.

e. Forward Foreign Currency Exchange Contracts

The Master Fund may enter forward foreign currency exchange contracts as a way of managing foreign exchange rate risk. The Master Fund may enter into these contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross hedge against either specific transactions or portfolio positions. The objective of the Master Fund’s foreign currency hedging transactions is to reduce the risk that the U.S. Dollar value of the Master Fund’s foreign currency denominated investments will decline in value due to changes in foreign currency exchange rates. All foreign currency exchange contracts are “marked-to-market” daily at the applicable translation rates resulting in unrealized gains or losses. Realized gains or losses are recorded at the time the foreign currency exchange contract is offset by entering into a closing transaction or by the delivery or receipt of the currency. Risk may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. Dollar.

2. Significant Accounting Policies (continued)

 e. Forward Foreign Currency Exchange Contracts (continued)

During the six month period ended September 30, 2012, the Master Fund entered into three short forward foreign currency exchange contracts and one long forward currency exchange contract. As disclosed in the Statement of Operations, the Master Fund had $1,013,151 in net realized gains, and a $392,308 change in net unrealized depreciation on forward foreign currency exchange contracts.

At September 30, 2012, the Master Fund had outstanding short foreign currency exchange contracts: 

									Unrealized
			Contract Amount						Appreciation
Settlement Date	Currency		Buy		Sell		Value		(Depreciation)			Counterparty
October 19, 2012		Euro (€)	$	12,249,700	€	10,000,000	$	12,860,395	$	(610,695	)	Barclays Capital

f. Investment Income

The Master Fund records distributions of cash or in-kind securities from Private Equity Investments at fair value based on the information from distribution notices when distributions are received. Thus, the Master Fund would recognize within the Statement of Operations its share of realized gains or (losses) and the Master Fund’s share of net investment income or (loss) based upon information received regarding distributions from managers of the Private Equity Investments. Unrealized depreciation on investments within the Statement of Operations includes the Master Fund’s share of unrealized gains and losses, realized undistributed gains, and the Master Fund’s share of undistributed net investment income or (loss) from Private Equity Investments for the relevant period.

g. Master Fund Expenses

The Master Fund bears all expenses incurred in the business of the Master Fund on an accrual basis, including, but not limited to, the following: all costs and expenses related to portfolio transactions and positions for the Master Fund’s account; legal fees; accounting, auditing, and tax preparation fees; custodial fees; fees for data and software providers; costs of insurance; registration expenses; managers’ fees; and expenses of meetings of the Board.

h. Income Taxes

For U.S. federal income tax purposes, the Master Fund is treated as a partnership, and each Member in the Master Fund is treated as the owner of its allocated share of the net assets, income, expenses, and the realized and unrealized gains (losses) of the Master Fund. Accordingly, no federal, state or local income taxes are paid by the Master Fund on the income or gains of the Master Fund since the Members are individually liable for the taxes on their allocated share of such income or gains of the Fund.

The Master Fund has adopted the authoritative guidance on accounting for and disclosure of uncertainty in tax positions. The Financial Accounting Standards Board (“FASB”) issued Accounting for Uncertainty in Income Taxes, which requires the Adviser to determine whether a tax position of the Master Fund is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority.

The Master Fund files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Master Fund is subject to examination by federal, state, local and foreign jurisdictions, where applicable. As of September 30, 2012, the tax years from the year 2009 forward remain subject to examination by the major tax jurisdictions under the statute of limitations.

2. Significant Accounting Policies (continued)

i. Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Master Fund 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 capital from operations during the reporting period. Actual results can differ from those estimates.

j. Recently Issued Accounting Pronouncements

In December 2011, FASB issued Accounting Standards Update (“ASU”) No. 2011-11 related to disclosures about offsetting assets and liabilities. The amendments in this ASU require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The ASU is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance requires retrospective application for all comparative periods presented. Management is currently evaluating the impact ASU No. 2011-11 will have on the financial statement disclosures.

3. Fair Value Measurements

As required by FASB’s Fair Value Measurements and Disclosures, investments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Estimated values may differ from the values that would have been used if a ready market existed or if the investments were liquidated at the valuation date. Fair Value Measurements and Disclosures established a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Master Fund’s investments. The inputs are summarized in the three broad levels listed below:

Valuation of Investments

·Level 1 – Quoted prices are available in active markets for identical investments as of the measurement date. The type of investment included in Level I include marketable securities that are primarily traded on a securities exchange or over-the-counter. The fair value is determined to be the last sale price on the determination date, or, if no sales occurred on any such day, the mean between the closing bid and ask prices on such day. As required by Fair Value Measurements and Disclosures, the Master Fund does not apply a blockage discount to the quoted price for these investments, even in situations where the Master Fund holds a large position and a sale could reasonably impact the quoted price.

·Level 2 – Pricing inputs are other than quoted prices in active markets (i.e. Level I pricing) and fair value is determined through the use of models or other valuation methodologies through direct or indirect corroboration with observable market data. Investments which are generally included in this category include corporate notes, convertible notes, warrants and restricted equity securities. The fair value of legally restricted equity securities generally may be discounted depending on the likely impact of the restrictions on liquidity and the Adviser’s estimates.

·Level 3 – Pricing inputs are unobservable for the investment and include situations where there is little, if any, market activity for the investment. The inputs into the determination of fair value require significant management judgment or estimation. Investments that are included in this category generally include equity investments that are privately owned, as well as convertible notes and warrants that are not actively traded. The fair value for investments using Level 3 pricing inputs are based on the Adviser’s estimates which consider a combination of various performance measurements including the timing of the transaction, the market in which the company operates, comparable market transactions, company performance and projections and various performance multiples as applied to earnings before interest, taxes, depreciation and amortization or a similar measure of earnings for the latest reporting period and forward earnings, as well as discounted cash flow analysis.

3. Fair Value Measurements (continued)

When the inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

Due to the inherent uncertainty of valuations, estimate values may materially differ from the values that would have been used had a ready market for the securities existed.

Investments	Level 1		Level 2		Level 3		Total
Direct Investments:
Direct Equity Investments	$	-	$	-	$	86,329,092	$	86,329,092
Direct Debt Investments		-		10,007,104		116,022,877		126,029,981

Total	$	142,987,762	$	10,007,104	$	366,335,376	$	519,330,242

The following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining value:

	Balance as of April 1, 2012		Realized Gain		Net change in unrealized			Gross purchases		Gross sales			Net transfers out of Level 3**			Balance as of September 30, 2012
Direct Investments:
Direct Equity Investments	$	51,293,009	$	-	$	8,293,847		$	28,729,153	$	(1,986,917	)	$	-		$	86,329,092
Direct Debt Investments		77,056,016		1,135,144		738,260			64,009,808		(16,909,247	)		(10,007,104	)		116,022,877

The amount of the net change in unrealized appreciation/depreciation for the six month period ended September 30, 2012 relating to investments in Level 3 assets still held at September 30, 2012 is $16,335,946, which is included as a component of net change in accumulated unrealized appreciation/(depreciation) on investments on the Statement of Operations.

*Direct private equity investments are private investments directly into the equity or debt of selected operating companies, often together with the management of the company. Secondary investments involve acquiring single or portfolios of assets on the secondary market. Primary investments are investments in newly established private equity partnerships where underlying portfolio companies are not known as of the time of investment.

**The Adviser has reassessed the criteria used to determine the valuation applied for the mezzanine investment in Dynamic Research Corp., and concluded that the methodology applied meets the criteria of a Level 2 investment rather than those of a Level 3 investment. As a consequence, the Adviser has decided to transfer the investment from Level 3 into Level 2 with effect from June 30, 2012.

Notes to Financial Statements – September 30, 2012 (unaudited) (continued)

3. Fair Value Measurements (continued)

In May 2011, the FASB issued ASU No. 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”)” (“ASU 2011-04”). ASU 2011-04 includes common requirements for measurement of and disclosure about fair value between U.S. GAAP and IFRS. ASU 2011-04 requires reporting entities to disclose quantitative information about the unobservable inputs used in the fair value measurements categorized within Level 3 of the fair value hierarchy. In addition, ASU 2011-04 requires reporting entities to make disclosures about amounts and reasons for all transfers in and out of Levels 1 and 2 of the fair value hierarchy. The new and revised disclosures are effective for interim and annual reporting periods beginning after December 15, 2011.

The Master Fund's valuation procedures have been adopted by the Master Fund's Board, which oversees the implementation of these procedures. The valuation procedures are implemented by the Adviser and the Master Fund's third party administrator, which report to the Board. For third-party information, Master Fund's administrator monitors and reviews the methodologies of the various pricing services employed by the Master Fund. The Adviser develops valuation techniques for private equity investments held by the Master Fund, which include discounted cash flow methods and market comparables.

The following is a summary of quantitative information about significant unobservable valuation inputs approved by the Adviser's Valuation Committee for Level 3 Fair Value Measurements for investments held as of September 30, 2012:

Type of Security	Fair Value at 9/30/2012			Valuation Technique(s)	Unobservable Input	Range (weighted average)
Direct Investments:
Direct Equity Investments	$	76,173,127		Market comparable companies	Enterprise Value to EBITDA multiple	6.00 x - 17.69 x (9.24)
		2,962,518		Discounted cash flow	Discount factor	17.88% - 20.00% (18.39%)
		2,690,377		Market comparable companies	Enterprise Value to Sales multiple	2.57 x - 2.57 x (2.57)
		4,503,070		Market comparable companies	Price to Earnings multiple	9.90 x – 9.90 x (9.90)
Direct Debt Investments		79,290,161		Market comparable companies	Enterprise Value to EBITDA multiple	6.23 x - 12.40x (9.62)
		9,640,905		Replacement cost	Transaction price	n/a
		27,091,811		Broker quotes	Indicative bid quotes for an inactive market	n/a
Total level 3 investments	$	202,351,969	*

* Amount excludes private equity fund investments of $163,983,407, which are valued on the basis of reported Net Asset Values.

Level 3 Direct Equity Investments valued by using an observable input factor are directly affected by a change in that factor. Level 3 Debt Investments are generally valued using a waterfall approach, including different seniority levels of debt. Thus the effect of a change in the unobservable input factor on the valuation of such investment is limited to the debt portion not covered by the enterprise value resulting from the valuation.

4. Allocation of Members’ Capital

Net profits or net losses of the Master Fund for each Allocation Period (as defined below) are allocated among and credited to or debited against the capital accounts of the Members. Each Allocation Period begins on the day after the last day of the preceding Allocation Period and ends at the close of business on the first to occur thereafter of: (1) the last day of a calendar month, (2) the last day of a taxable year; (3) the day preceding a day on which Interests are purchased, (4) a day on which Interests are repurchased by the Master Fund pursuant to tenders of Interests by Members, or (5) a day on which any amount is credited to or debited from the capital account of any Member other than an amount to be credited to or debited from the capital accounts of all Members in accordance with their respective investment percentages.

5. Subscription and Repurchase of Members’ Interests

Interests are generally offered for purchase as of the first day of each calendar month, except that Interests may be offered more or less frequently as determined by the Board in its sole discretion.

Notes to Financial Statements – September 30, 2012 (unaudited) (continued)

5. Subscription and Repurchase of Members’ Interests (continued)

The Board may, from time to time and in its sole discretion, cause the Master Fund to repurchase Interests from Members pursuant to written tenders by Members at such times and on such terms and conditions as established by the Board. In determining whether the Master Fund should offer to repurchase Interests, the Board considers the recommendation of the Adviser, as well as a variety of other operational, business and economic factors. The Adviser anticipates recommending to the Master Fund’s Board that, under normal circumstances, the Master Fund conduct repurchase offers of no more than 5% of the Master Fund’s net assets quarterly on or about each January 1^st, April 1^st, July 1^st and October 1^st. The Master Fund does not intend to distribute to the Members any of the Master Fund’s income, but currently expects to reinvest substantially all income and gains allocable to the Members.

6. Management Fees, Incentive Allocation, and Fees and Expenses of Managers

The Adviser is responsible for providing day-to-day investment management services to the Master Fund, subject to the ultimate supervision of and subject to any policies established by the Board, pursuant to the terms of an investment management agreement with the Master Fund (the "Investment Management Agreement"). Under the Investment Management Agreement, the Adviser is responsible for developing, implementing and supervising the Master Fund's investment program. In consideration for such services, the Master Fund pays the Adviser a monthly management fee equal to 1/12^th of 1.25% (1.25% on an annualized basis) of the greater of (i) the Master Fund’s net asset value and (ii) the Master Fund’s net asset value less cash and cash equivalents plus the total of all commitments made by the Master Fund that have not yet been drawn for investment. In no event will the Investment Management Fee exceed 1.50% as a percentage of the Master Fund’s net asset value.

In addition, at the end of each calendar quarter (and at certain other times), an amount (the “Incentive Allocation”) equal to 10% of the excess, if any, of (i) the allocable share of the net profits of the Master Fund for the relevant period of each Member over (ii) the then balance, if any, of that Member’s Loss Recovery Account (as defined below) will be debited from such Member’s capital account and credited to a capital account of the Adviser (or, to the extent permitted by applicable law, of an affiliate of the Adviser) in the Master Fund (the “Incentive Allocation Account”) maintained solely for the purpose of being allocated the Incentive Allocation and thus, does not participate in the Members’ Equity Allocation.

The Master Fund maintains a memorandum account for each Member (each, a “Loss Recovery Account”). Each Member’s Loss Recovery Account has an initial balance of zero and is (i) increased upon the close of each Allocation Period by the amount of the relevant Member’s allocable share of the net losses of the Master Fund for the Allocation Period, and (ii) decreased (but not below zero) upon the close of such Allocation Period by the amount of such Member’s allocable share of the net profits of the Master Fund for the Allocation Period. The Incentive Allocation is calculated, charged to each Member and credited to the Incentive Allocation Account as of the end of each Allocation Period. The Allocation Period with respect to a Member whose Interest is repurchased or is transferred in part is treated as ending only for the portion of Interests so repurchased or transferred. In addition, only the net profits of the Master Fund, if any, and the balance of the Loss Recovery Account attributable to the portion of the Interest being repurchased or transferred (based on the Member’s capital account amount being so repurchased or transferred) is taken into account in determining the Incentive Allocation for the Allocation Period then ending. The Member’s Loss Recovery Account is not adjusted for such Member’s allocable share of the net losses of the Master Fund, if any, for the Allocation Period then ending that are attributable to the portion of the Interest so repurchased or transferred. For the six month period ended September 30, 2012 an aggregate Incentive Allocation of $2,478,482 was credited to the Incentive Allocation Account.

Each member of the Board who is not an “interested person” of the Master Fund, as defined by the 1940 Act (the “Independent Managers”), receives a fee of $35,000 per year. In addition, the Master Fund pays an additional fee of $10,000 per year to the Chairman of the Board and to the Chairman of the Audit Committee. All Board members are reimbursed by the Master Fund for all reasonable out-of-pocket expenses incurred by them in performing their duties.

7. Accounting, Administration, and Custodial Agreement

In consideration for accounting, administrative, and recordkeeping services, the Master Fund pays UMB Fund Services, Inc. (the “Administrator”) a monthly administration fee based on the month-end net asset value of the Master Fund, subject to certain minimums. The Administrator also provides regulatory administrative services, transfer agency functions, and shareholder services at an additional cost. For these services the Administrator receives a fixed monthly fee, based upon average net assets, and a monthly fee based on the number of Member accounts as well as reasonable out of pocket expenses. For the six month period ended September 30, 2012, the total administration fee was $162,563.

8. Investment Transactions

Total purchases of Private Equity Investments for the six month period ended September 30, 2012 amounted to $130,748,632. Total distribution proceeds from sale, redemption, or other disposition of Private Equity Investments for the six month period ended September 30, 2012 amounted to $23,488,640. The cost of investments in Private Equity Investments for U.S. federal income tax purposes is adjusted for items of taxable income allocated to the Master Fund from such Private Equity Investments. The Master Fund relies upon actual and estimated tax information provided by the managers of the Private Equity Investments as to the amounts of taxable income allocated to the Master Fund as of September 30, 2012.

9. Indemnification

In the normal course of business, the Master Fund enters into contracts that provide general indemnification. The Master Fund’s maximum exposure under these agreements is dependent on future claims that may be made against the Master Fund under such agreements, and therefore cannot be established; however, based on experience, the risk of loss from such claims is considered remote.

10. Commitments

As of September 30, 2012, the Master Fund had contributed 65% or $366,743,646 of the total of $560,778,007 of its capital commitments to its Private Equity Investments. With respect to its (i) Direct Investments it had contributed $220,754,508 of $226,875,266 in total commitments, (ii) Secondary Investments it had contributed $130,128,543 of $232,409,136 in total commitments, and (iii) Primary Investments contributed $15,860,595 of $101,493,605 in total commitments, in each case, as of September 30, 2012.

11. Risk Factors

An investment in the Master Fund involves significant risks, including industry risk, liquidity risk, interest rate risk and economic conditions risk, that should be carefully considered prior to investing and should only be considered by persons financially able to maintain their investment and who can afford a loss of a substantial part or all of such investment. The Master Fund invests substantially all of its available capital in Private Equity Investments. These investments are generally restricted securities that are subject to substantial holding periods and are not traded in public markets, so that the Master Fund may not be able to resell some of its holdings for extended periods, which may be several years. The Master Fund may have a concentration of investments, as permitted by the Confidential Private Placement Memorandum, in a particular industry or sector. Investment performance of the sector may have a significant impact on the performance of the Master Fund. The Master Fund’s investments are also subject to the risk associated with investing in private equity securities. The investments in private equity securities are illiquid, can be subject to various restrictions on resale, and there can be no assurance that the Master Fund will be able to realize the value of such investments in a timely manner.

Interests in the Master Fund provide limited liquidity because Members will not be able to redeem Interests on a daily basis due to the fact that the Master Fund is a closed-end fund. Therefore investment in the Master Fund is suitable only for investors who can bear the risks associated with the limited liquidity of Interests and should be viewed as a long-term investment. No guarantee or representation is made that the investment objective will be met.

A further discussion of the risks associated with an investment in the Master Fund is provided in the Confidential Private Placement Memorandum and Statement of Additional Information.

12. Subsequent Events

Management has evaluated the impact of all subsequent events on the Master Fund through November 29, 2012, the date the financial statements were issued, and has determined that the following subsequent events require disclosure in the financial statements. Effective October 1, 2012 and November 1, 2012, there were additional capital contributions to the Master Fund in the amounts of $20,756,506 and $21,704,055, respectively. In addition, the Master Fund received, pending acceptance, tender requests in the amount of $6,385,550, which will be effective as of December 31, 2012.
