Partners Group Private Equity (Institutional TEI), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited)

1. Organization

Partners Group Private Equity (Institutional TEI), LLC (the “Fund”) invests substantially all of its assets in Partners Group Private Equity (Offshore II), LDC (the “Offshore Fund”). The Offshore Fund is a Cayman Islands limited duration company with the same investment objective as the Fund. The Offshore Fund serves solely as an intermediary entity through which the Fund invests in Partners Group Private Equity (Master Fund), LLC (the “Master Fund”). The Offshore Fund enables tax-exempt Members (as defined below) to invest without receiving certain income in a form that would otherwise be taxable to such tax-exempt Members regardless of their tax-exempt status. The Fund owns 100% of the participating beneficial interest of the Offshore Fund. Where these Notes to Consolidated Financial Statements discuss the Fund’s investment in the Master Fund, it means its investment in the Master Fund through the Offshore Fund.

The Fund was organized as a limited liability company under the laws of the State of Delaware on May 25, 2010 and commenced operations on December 1, 2011. 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 invests substantially all of its assets in limited liability company interests (“Interests”) in the Master Fund, a limited liability company organized under the laws of the State of Delaware, which is also registered under the 1940 Act. In addition to the Fund, three other closed-end, non-diversified investment companies also invest substantially all of their respective assets in Interests in the Master Fund (the Fund and each such other investment company, individually a “Feeder Fund” and collectively, the “Feeder Funds”). Collectively, the Feeder Funds own all of Interests in the Master Fund.

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. The Board also acts as the board of managers of the Master Fund (the “Master Fund Board”) and of each of the other Feeder Funds. As 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 in the Fund (“Units”) are offered only to investors 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. Holders of Units (“Members”) of the Fund do not own any direct interest in the Master Fund.

The Fund’s consolidated financial statements should be read in conjunction with the Master Fund’s consolidated financial statements, which are included as Appendix I.

At September 30, 2014, the Fund owned 5.54% 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 consolidated financial statements.

a. Basis of Accounting

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

b. Valuation of Investments

The Fund values its investment in the Master Fund at the net asset value of the Interests in the Master Fund owned by the Fund. The net asset value of the Interests in the Master Fund is determined by the Master Fund. Investments held by the Master Fund include direct equity and debt investments in operating companies (“Direct Investments”) and primary and secondary investments in private equity funds (“Private Equity Fund Investments”; Direct Investments and Private Equity Fund Investments, collectively, “Private Equity Investments”). The Master Fund values interests in Private Equity Investments at fair value in accordance with procedures (the “Valuation Procedures”), which have been approved by the Board and the Master Fund Board. The fair values of Private Equity Investments determined on behalf of the Master Fund by the Adviser in accordance with the Valuation Procedures are estimates. In the case of a Private Equity Fund Investment, the fair value is net of management and performance incentive fees or allocations that may be payable pursuant to the constituent documents of such investment fund.

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

c. Allocations from the Master Fund

In accordance with U.S. GAAP, the Fund, as the holder of Interests in the Master Fund, records in its consolidated financial statements its allocated portion of income, expense, realized gains and losses and unrealized appreciation and depreciation in the Master Fund.

d. Fund Level Income and Expenses

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

e. Expense Limitation Agreement

Effective September 26, 2011, the Adviser entered into an expense limitation agreement (the “Expense Limitation Agreement”) with the Fund, whereby 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 in compliance with 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, 2014, there were no amounts waived or assumed that are subject for recoupment by Adviser.

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 U.S. 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 Adviser determines 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 consolidated 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 U.S. federal, state, local and foreign jurisdictions, where applicable. As of September 30, 2014, the tax years from the year 2011 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, those 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.

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

i. Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires that management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated 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. Consolidated Financial Statements

The asset, liability, and equity accounts of the Fund are consolidated with the Offshore Fund as presented in the Consolidated Statement of Assets, Liabilities and Members’ Equity. All significant intercompany accounts and transactions have been eliminated in consolidation.

3. Fair Value Measurements

The Fund records its investment in the Master Fund at the net asset value of the Interests in the Master Fund owned by the Fund. 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 consolidated financial statements.

4. Allocation to Members’ Capital Accounts

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 Members’ capital accounts in proportion to the number of Units owned by 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 Units 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 in its records for each Member. As of any date, the capital account balance of a Member is 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) are 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. Additionally, such Member’s Units are 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) are 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. Additionally, such Member’s Units are increased thereby as appropriately determined by the Fund. As of September 30, 2014, there have been no special items or accrued receivables allocated to Members’ capital accounts.

5. Subscriptions and Repurchase of Units

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 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 1st, April 1st, July 1st and October 1st. 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 first anniversary of the Member’s purchase of such Units.

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited) (continued)

6. Related Party Transactions and Other

An incentive allocation (“Incentive Allocation”) is calculated at the Master Fund and allocated to the Fund based on the Fund’s ownership of Interests 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). The Incentive Allocation is 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, and thus, the Incentive Allocation Account does not participate in the net profits and losses of the Master Fund.

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 for 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, 2014, an Incentive Allocation of $369,056 was credited to the Incentive Allocation Account from the Fund’s capital account in the Master 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 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, 2014, the Fund paid $27,936 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. As a result, 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 Fund’s investment objective will be met.

A further discussion of the risks associated with the Fund’s investment in the Master Fund is provided in Note 11 of the Notes to the Master Fund’s consolidated financial statements, the Fund’s Confidential Private Placement Memorandum and the Fund’s Statement of Additional Information.

8. Indemnification

In the normal course of business, the Fund enters into contracts that may 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 management’s 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 and has determined that there were no subsequent events that require disclosure in the consolidated financial statements.

Secondary investments involve acquiring single or portfolios of assets on the secondary market.

** The Fair Value of any Direct Investment may not necessarily reflect the current or expected future performance of such Direct Investment or the Fair Value of the Master Fund’s interest in such Direct Investment. Furthermore, the Fair Value of any Direct Investment has not been calculated, reviewed, verified or in any way approved by such Direct Investment or its general partner, manager or sponsor (including any of its affiliates). Please see Note 2.b for further detail regarding the valuation policy of the Master Fund.

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2014 (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. As 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 may make investments through its wholly-owned subsidiary, Partners Group Private Equity (Subholding), LLC (the “Subsidiary”). The Board has oversight responsibility for the Master Fund’s investment in the Subsidiary and the Master Fund’s role as sole member of the Subsidiary.

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, directly or indirectly, of the Master Fund (“Members”).

2. Significant Accounting Policies

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

a. Basis of Accounting

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

b. Valuation of Investments

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

The Master Fund estimates the fair value of its Private Equity Investments in conformity with U.S. GAAP. The Master Fund’s valuation procedures (the “Valuation Procedures”), which have been approved by the Board, require evaluation of all relevant factors available at the time the Master Fund values its investments. The inputs or methodologies used for valuing the Master Fund’s Private Equity Investments are not necessarily an indication of the risk associated with investing in those 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 the end of each reporting period. Quoted market prices or dealer quotes for certain similar instruments are used for long-term debt investments 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 fair values of Private Equity Fund Investments determined by the Adviser in accordance with the Valuation Procedures are estimates. These estimates are net of management and performance incentive fees or allocations payable pursuant to the respective organizational documents of the Private Equity Fund Investments. Ordinarily, the fair value of a Private Equity Fund Investment is based on the net asset value of that Private Equity Fund Investment reported by its investment manager. If the Adviser determines that the most recent net asset value reported by the investment manager of a Private Equity Fund Investment does not represent fair value or if the manager of a Private Equity Fund Investment fails to report a net asset value to the Master Fund, a fair value determination is made by the Adviser in accordance with the Valuation Procedures. In making that determination, the Adviser will consider whether it is appropriate, in light of all relevant circumstances, to value such Private Equity Fund Investment at the net asset value last reported by its

b. Valuation of Investments (continued)

investment manager, or whether to adjust such value to reflect a premium or discount to such net asset value. 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.

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, or (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 are 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.

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, those 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, 2014 the Master Fund has 45 investments denominated in Euros, five investments denominated in British Pounds, two investments denominated in Australian Dollars, two investments denominated in Norwegian Kronor, two investments denominated in Swiss Francs, one investment denominated in Brazilian Real, one investment denominated in Hong Kong Dollars, one investment denominated in Japanese Yen and one investment denominated in Swedish Kronor. 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 forward 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 forward 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.

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

e. Forward Foreign Currency Exchange Contracts (continued)

During the six month period ended September 30, 2014, the Master Fund entered into three short forward foreign currency exchange contracts. As disclosed in the Consolidated Statement of Operations, the Master Fund had $227,152 in net realized gains, and a $5,314,416 change in net unrealized appreciation on forward foreign currency exchange contracts.

At September 30, 2014, the Master Fund had two outstanding short forward foreign currency exchange contracts:

		Contract Amount			Unrealized
Settlement Date	Currency	Buy	Sell	Value	Appreciation (Depreciation)	Counterparty
October 23, 2014	Euro (€)	$60,707,025	€45,000,000	$56,854,806	$3,852,219	Barclays Capital
December 18, 2014	Euro (€)	$38,237,409	€30,000,000	$37,913,683	$323,726	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 Consolidated 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 Private Equity Investments. Unrealized appreciation/depreciation on investments within the Consolidated Statement of Operations includes the Master Fund’s share of unrealized gains and losses, realized undistributed gains/losses, 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; board fees; and expenses of meetings of the Board.

h. Costs Relating to Purchases of Secondary Investments

Costs relating to purchases of secondary investments consist of imputed expenses relating to the amortization of deferred payments on investments purchased in secondary transactions. Such expenses are recognized on a monthly basis until the due date of a deferred payment. At due date the net present value of such payment equals the notional amount due to the respective counterparty.

i. Income Taxes

For U.S. federal income tax purposes, the Master Fund is treated as a partnership, and each Member of 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 U.S. 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 Master Fund.

The Adviser determines whether a tax position 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 consolidated 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.

Notes to Consolidated Financial Statements – September 30, 2014 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

i. Income Taxes (continued)

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 U.S. federal, state, local and foreign jurisdictions, where applicable. As of September 30, 2014, the tax years from the year 2010 forward remain subject to examination by the major tax jurisdictions under the statute of limitations.

j. 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.

k. Consolidated Financial Statements

The Consolidated Schedule of Investments, Statement of Assets and Liabilities, Statement of Operations, Statement of Changes in Members’ Equity, Statement of Cash Flows and Financial Highlights of the Master Fund include the accounts of the Subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation.

l. Disclosures about Offsetting Assets and Liabilities

The Master Fund is subject to Financial Accounting Standards Board’s (“FASB”) Disclosures about Offsetting Assets and Liabilities which requires 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 guidance requires retrospective application for all comparative periods presented.

For financial reporting purposes, the Master Fund does not offset derivative assets and liabilities that are subject to Master Netting Agreements (“MNA”) or similar arrangements in the Consolidated Statement of Assets and Liabilities. The Master Fund has adopted the new disclosure requirements on offsetting in the following table:

The following table presents the Master Fund’s derivative assets by type, net of amounts available for offset under a MNA and net of the related collateral received by the Master Fund as of September 30, 2014:

Counterparty	Gross Amounts of Recognized Assets	Gross Amounts Offset in the Consolidated Statement of Assets and Liabilities	Net Amounts of Assets Presented in the Consolidated Statement of Assets and Liabilities	Collateral Pledged	Net Amount 1
Barclays Capital	$4,175,945	$—	$—	$—	$4,175,945

1 Net amount represents the net amount receivable from the counterparty in the event of default.

3. Fair Value Measurements

In conformity with U.S. GAAP, 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. A three-tier hierarchy is used 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 investments included in Level 1 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. 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 1 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 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 and/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 that 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. The following table presents the Master Fund’s investments at September 30, 2014 measured at fair value. Due to the inherent uncertainty of valuations, estimated 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

The amount of the net change in unrealized appreciation for the six month period ended September 30, 2014 relating to investments in Level 3 assets still held at September 30, 2014 is $28,398,295, which is included as a component of net change in accumulated unrealized appreciation on investments on the Consolidated 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 Master Fund’s Valuation Procedures have been approved by the Board. The Valuation Procedures are implemented by the Adviser and the Master Fund’s third party administrator, both of which report to the Board. For third-party information, the Master Fund’s administrator monitors and reviews the methodologies of the various pricing services employed by the Master Fund. The Adviser employs valuation techniques for Private Equity Investments held by the Master Fund, which include discounted cash flow methods and market comparables. The Adviser has established a committee (the “Valuation Committee”) to oversee the valuation of the Master Fund’s investments pursuant to the Valuation Procedures. The Adviser and one or more of its affiliates may act as investment advisers to clients other than the Master Fund that hold Private Equity Investments held by the Master Fund. In such cases, the Valuation Committee may value such Private Equity Investments in consultation with its affiliates. Valuation determinations by the Adviser and its affiliates for a Private Equity Investment held by other clients may result in different values than those ascribed to the same Private Equity Investment held by the Master Fund. This situation can arise in particular when reconciling fair valuation differences between U.S. GAAP and accounting standards applicable to such other clients.

3. Fair Value Measurements (continued)

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, 2014:

Type of Security	Fair Value at 9/30/2014		Valuation Technique(s)	Unobservable Input	Range (weighted average)
Direct Investments:
Direct Equity Investments	$	296,391,084	Market comparable companies	Enterprise Value to EBITDA multiple	4.20 x - 15.10 x(10.04 x)
		3,289,539	Discounted cash flow	Discount factor	14.40% - 20.00%(15.20%)
		1,115,457	Market comparable companies	Price to Book ratio	1.00 x - 1.00 x(1.00 x)
		2,702,726	Market comparable companies	Enterprise Value to Sales multiple	2.56 x - 2.56 x(2.56 x)
		2,276,465	Price to Earnings multiple	Price to Earnings multiple	1.42 x - 1.42 x(1.42 x)
		590,699	Exit price	Recent transaction price	n/a - n/a (n/a)
Direct Debt Investments	$	4,862,125	Market comparable companies	Enterprise Value to EBITDA multiple	8.50 x - 8.50 x(8.50 x)
		71,313,190	Discounted cash flow	Discount factor	7.09% - 14.98%(11.89%)
		107,989,005	Quoted Debt	Quoted Debt	n/a - n/a (n/a)
		7,453,760	Exit price	Recent transaction price	n/a - n/a (n/a)

Level 3 Direct Equity Investments valued by using an unobservable input factor are directly affected by a change in that factor. For Level 3 Direct Debt Investments, the Master Fund arrives at a fair value through the use of an earnings and multiples analysis and a discounted cash flows analysis which consider credit risk and interest rate risk of the particular investment. Significant increases or decreases in these inputs in isolation would result in a significantly lower or higher fair value measurement.

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. “Allocation Period” means a period that 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 newly issued Interests are purchased by Members, (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 by Members 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.

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 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 1st, April 1st, July 1st and October 1st. At the present time, the Master Fund does not intend to distribute to the Members any of the Master Fund’s income, but instead 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 1/12th 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) is 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 being allocated the Incentive Allocation and thus, the Incentive Allocation Account does not participate in the net profits or losses of the Master Fund.

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 for 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, 2014 an aggregate Incentive Allocation of $7,042,124 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 and Administration Agreement

UMB Fund Services, Inc. (the “Administrator”) serves as administrator and accounting agent to the Master Fund and provides certain accounting, record keeping and investor related services. For these services the Administrator receives a fixed monthly fee, based upon average net assets, fees on portfolio transactions, as well as reasonable out of pocket expenses. For the six month period ended September 30, 2014, the Master Fund paid $266,188 in administration and accounting fees.

8. Investment Transactions

Total purchases of Private Equity Investments for the six month period ended September 30, 2014 amounted to $130,649,542. Total distribution proceeds from sale, redemption, or other disposition of Private Equity Investments for the six month period ended September 30, 2014 amounted to $100,890,102. 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, 2014.

9. Indemnification

In the normal course of business, the Master Fund may enter 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 management’s experience, the risk of loss from such claims is considered remote.

10. Commitments

As of September 30, 2014, the Master Fund had contributed 79% or $1,097,842,372 of the total of $1,384,956,231 of its capital commitments to its Private Equity Investments. With respect to its (i) Direct Investments it had contributed $661,345,347 of $661,498,209 in total commitments, (ii) secondary Private Equity Investments it had contributed $365,262,809 of $546,149,274 in total commitments, and (iii) primary Private Equity Investments it had contributed $71,234,216 of $177,308,748 in total commitments, in each case, as of September 30, 2014.

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 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. Private Equity Fund Investments are generally closed-end private equity partnerships with no right to withdraw prior to the termination of the partnership. The frequency of withdrawals is dictated by the governing documents of the Private Equity Fund Investments.

Interests in the Master Fund provide limited liquidity because Members will not be able to redeem Interests on a daily basis because 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.

12. Subsequent Events

Management has evaluated the impact of all subsequent events on the Master Fund and has determined that there were no subsequent events that require disclosure in the consolidated financial statements.
