Partners Group Private Equity (Institutional), LLC

(a Delaware Limited Liability Company)

Notes to Financial Statements – March 31, 2015

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 invests 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. 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”) do not own any direct interest in the Master Fund.

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

At March 31, 2015, the Fund owned 11.31% of the Interests in the Master Fund.

2. Significant Accounting Policies

The Fund is an investment company. Accordingly, these financial statements have applied the guidance set forth in Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. 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 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 Private Equity Fund Investments.

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 financial statements its allocated portion of income, expense, realized gains and losses and unrealized appreciation and depreciation in the Master Fund.

Notes to Financial Statements – March 31, 2015 (continued)

2. Significant Accounting Policies (continued)

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 February 1, 2010, 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 March 31, 2015, 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 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 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 March 31, 2015, 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.

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 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.

Notes to Financial Statements – March 31, 2015 (continued)

2. Significant Accounting Policies (continued)

j. Recently Issued Accounting Pronouncement

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-7, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), modifying ASC 946 Financial Services – Investment Companies. Under the modifications, investments in affiliated and private investment funds valued at NAV are no longer included in the fair value hierarchy. ASU 2015-7 is effective for fiscal years beginning on or after December 15, 2015, and interim periods within those annual periods. Early application is permitted. Management is currently evaluating the implications of ASU 2015-7 and its impact on financial statements disclosures.

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 March 31, 2015, 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 Financial Statements – March 31, 2015 (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 year ended March 31, 2015, an Incentive Allocation of $1,450,143 was credited to the Incentive Allocation Account from the Fund’s capital account in the Master Fund.

The Adviser has elected to make a voluntary contribution to the Fund in the amount of $17,245 as a payment made to reimburse the Fund for a loss resulting from repurchases of Units that were impacted by the valuation error further discussed in Note 7, all of which was receivable at March 31, 2015, and is included in Receivable from Adviser in the Statement of Assets, Liabilities and Members’ Equity.

At March 31, 2015, the Adviser owned $13,024,006 of the Fund (9.49% 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.

7. Correction of an Error

During 2015, the Adviser discovered an error at the Master Fund relating to the overstatement in the valuation of one of the Master Fund’s Secondary Investments included in the prior year financial statements. The error impacted the Fund’s investment in the Master Fund in the amount of $451,510 and also impacted the allocations of income and loss from the Master Fund. See footnote 11 of the Master Fund’s financial statements for a description of the errors at the Master Fund. The Adviser evaluated the impact of the errors at the Fund and concluded that they were not material to the Fund’s 2014 financial statements taken as a whole. However, the Fund’s management elected to revise the 2014 financial statements of the Fund in order to properly present the amounts in the correct period. As the prior period financial statements are not presented herein, an adjustment to the Fund’s members’ equity at March 31, 2014 in the amount of $451,510 has been recorded to reflect the impact of the errors.

The impacted line items which are presented for comparative purposes are presented below as follows:

8. 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 12 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.

9. 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.

10. 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 financial statements.

For the Year Ended March 31, 2015

To the Board of Managers and Members ofPartners Group Private Equity (Master Fund), LLC:

In our opinion, the accompanying consolidated statement of assets, liabilities and members’ equity, including the consolidated schedule of investments, and the related consolidated statements of operations, of changes in members’ equity and of cash flows and the financial highlights present fairly, in all material respects, the financial position of Partners Group Private Equity (Master Fund), LLC (the “Fund”) at March 31, 2015, the results of its operations and its cash flows for the year then ended, the changes in its members’ equity for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These consolidated financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits of these consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2015 by correspondence with the management of Direct Investments and Private Equity Fund Investments or agent banks and the application of alternative auditing procedures where replies had not been received, provide a reasonable basis for our opinion.

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – March 31, 2015

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” or “Managers”) 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 Master Fund is an investment company. Accordingly, these financial statements have applied the guidance set forth in Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. 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 latest round of 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 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 currencies other than the U.S. Dollar 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 March 31, 2015 the Master Fund has 48 investments denominated in Euros, four 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.

e. Forward Foreign Currency Exchange Contracts (continued)

During the year ended March 31, 2015, the Master Fund entered into six long/short forward foreign currency exchange contracts. As disclosed in the Consolidated Statement of Operations, the Master Fund had $9,680,395 in net realized gains, and a $8,713,169 change in net unrealized appreciation on forward foreign currency exchange contracts.

At March 31, 2015, the Master Fund had two outstanding long/short forward foreign currency exchange contract:

		Contract Amount			Unrealized Appreciation (Depreciation)
Settlement Date	Currency	Buy	Sell	Value		Counterparty
April 23, 2015	Euro (€)	$53,570,055	€46,200,000	$50,033,355	$3,536,700	Barclays Capital
April 23, 2015	Euro (€)	$60,460,904	€52,100,000	$56,422,906	$4,037,998	Bank of America

f. Investment Income

The Master Fund records distributions of cash or in-kind securities from a Private Equity Investment at fair value based on the information contained in distribution notices provided to the Master Fund by the Private Equity Investment 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.

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 March 31, 2015, the tax years from the year 2011 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, Liabilities and Members’ Equity, 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, Liabilities and Members’ Equity. 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 March 31, 2015:

Counterparty	GrossAmounts 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	$3,536,700	$—	$—	$—	$3,536,700
Bank of America	$4,037,998	$—	$—	$—	$4,037,998

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

m. Recently Issued Accounting Pronouncement

In February 2015, FASB issued Accounting Standards Update (“ASU”) 2015-02, Amendments to the Consolidation Analysis (Topic 810). ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIE”) or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIE’s, and provides other updates on guidance regarding consolidation. ASU 2015-02 is effective for fiscal years beginning after December 15, 2016. Management is currently evaluating the implications of ASU 2015-02 and its impact on the financial statements and disclosures.

In April 2015, FASB issued ASU 2015-7, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), modifying ASC 946 Financial Services – Investment Companies. Under the modifications, investments in affiliated and private investment funds valued at net asset value are no longer included in the fair value hierarchy. ASU 2015-7 is effective for fiscal years beginning on or after December 15, 2015, and interim periods within those annual periods. Early application is permitted. Management is currently evaluating the implications of ASU 2015-7 and its impact on the financial statements and disclosures.

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 March 31, 2015 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.

The amount of the net change in unrealized appreciation for the year ended March 31, 2015 relating to investments in Level 3 assets still held at March 31, 2015 is $50,939,874, which is included as a component of net change in accumulated unrealized appreciation on investments on the Consolidated Statement of Operations.

* In the table above: “Direct Investments” are private investments directly into the equity or debt of selected operating companies, often together with the management of the company, “Secondary Investments” are Private Equity Fund Investments acquired in the secondary market, and “Primary Investments’ are Private Equity Fund Investments in newly established private equity partnerships where underlying portfolio companies are not known as of the time of investment.

** The item includes a correction of an error for the year ended March 31, 2014. Refer to Note 11 for further clarification.

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 March 31, 2015:

Type of Security	Fair Value at 3/31/2015(000’s)		Valuation Technique(s)	Unobservable Input	Range(weighted average)
Direct Investments:
Direct Equity Investments	$	317,632	Market comparable companies	Enterprise Value to EBITDA multiple	4.20 x – 14.23 x (10.50x)
		360	Discounted cash flow	Discount factor	20.00% – 20.00% (20.00%)
		2,888	Third party valuation	Valuation appraisal	n/a – n/a (n/a)
		4,014	Price to Earnings multiple	Price to Earnings multiple	8.80 x – 8.80 x (8.80x)
		588	Market comparable companies	Price to Book ratio	1.02 x – 1.02 x (1.02x)
		3,354	Market comparable companies	Enterprise Value to Sales multiple	2.78 x – 2.78 x (2.78x)
		8	Exit price	Recent transaction price	n/a - n/a (n/a)
		11,000	Recent financing	Recent transaction price	n/a - n/a (n/a)
Direct Debt Investments	$	2,480	Market comparable companies	Enterprise Value to EBITDA multiple	8.50 x – 8.50 x (8.50x)
		66,527	Discounted cash flow	Discount factor	10.64% – 14.97% (12.61%)
		107,049	Quoted debt	Quoted debt	n/a - n/a (n/a)
		10,274	Recent financing	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. Each “Allocation Period” is 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 year ended March 31, 2015 an aggregate Incentive Allocation of $13,915,947 was credited to the Incentive Allocation Account.

Effective January 1, 2015, the Master Fund will pay each Manager a retainer of $35,000 per year. Prior to January 1, 2015, the Master Fund only paid each Manager who was not an “interested person” of the Master Fund, as defined by the 1940 Act (each an “Independent Manager”), a retainer of $35,000 per year. In addition, the Master Fund pays an additional retainer of $10,000 per year to the Chairman of the Board and to the Chairman of the audit committee of the Board, each of whom is an Independent Manager. Each Manager is reimbursed by the Master Fund for all reasonable out-of-pocket expenses incurred in performing his 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 year ended March 31, 2015, the Master Fund paid $548,879 in administration and accounting fees.

8. Investment Transactions

Total purchases of Private Equity Investments for the year ended March 31, 2015 amounted to $202,021,375. Total distribution proceeds from sale, redemption, or other disposition of Private Equity Investments for the year ended March 31, 2015 amounted to $163,931,829. 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 March 31, 2015.

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 March 31, 2015, the Master Fund had contributed 82.81% or $1,158,711,131 of the total of $1,399,322,272 of its capital commitments to its Private Equity Investments. With respect to its (i) Direct Investments it had contributed $687,428,041 of $674,636,345 in total commitments, (ii) secondary Private Equity Investments it had contributed $381,310,342 of $509,399,116 in total commitments, and (iii) primary Private Equity Investments it had contributed $89,972,747 of $215,286,811 in total commitments, in each case, as of March 31, 2015.

Notes to Consolidated Financial Statements – March 31, 2015 (continued)

11. Correction of an Error

During 2015, the Adviser discovered an error relating to the overstatement in the valuation of one of the Fund’s Secondary Investments included in the prior year financial statements. The error impacted the Private Equity Investments by $6,381,225, reduced management fees by $24,616 and resulted in an over allocation of Incentive Allocation to the Adviser of $635,661, and as a result of the allocation, the Master Fund over accrued capital tenders to the Adviser of $640,107. The Adviser evaluated the impact of the errors and concluded that they were not material to the 2014 financial statements taken as a whole. However, the Master Fund’s management elected to revise the 2014 financial statements in order to properly present the amounts in the correct period. As the prior period financial statements are not presented herein, an adjustment to the 2014 members’ equity in the amount of $5,716,503 has been recorded to reflect the impact of the errors.

The impacted line items which are presented for comparative purposes are presented below as follows:

12. 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.

13. 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.

Approval of Investment Management Agreement

At a meeting of the Board held on December 2, 2014, the Board, including a majority of the Independent Managers, approved by a unanimous vote the continuation of the Investment Management Agreement (the “Agreement”).

In advance of the meeting, the Independent Managers requested and received extensive materials from the Adviser to assist them in considering the approval of the Agreement. The materials provided by the Adviser included detailed comparative information relating to the performance, advisory fees and other expenses of the Master Fund and the Feeder Funds (collectively, the “Funds”).

The Board engaged in a detailed discussion of the materials with management of the Adviser. The Independent Managers then met separately with independent counsel to the Independent Managers for a full review of the materials. Following this session, the full Board reconvened and after further discussion determined that the information presented provided a sufficient basis upon which to approve the Agreement.

Discussion of Factors Considered

The Board considered, among other things: (1) the nature and quality of the advisory services rendered, including, the complexity of the services provided; (2) the experience and qualifications of the personnel that provide such services; (3) the fee structure and the expense ratios in relation to those of other investment companies having comparable investment policies and limitations; (4) the direct and indirect costs incurred by the Adviser and its affiliates in performing advisory services for the Master Fund, the basis of determining and allocating these costs, and the profitability to the Adviser and its affiliates in performing such services; (5) possible economies of scale arising from any anticipated growth of the Funds and the extent to which these would be passed on to the Funds; (6) other compensation or possible benefits to the Adviser and its affiliates arising from their advisory and other relationships with the Master Fund; (7) possible alternative fee structures or bases for determining fees; (8) the fees charged by the Adviser and other investment advisers, to similar clients and in comparison to industry fees for similar services; and (9) possible conflicts of interest that the Adviser may have with respect to the Funds.

The Board concluded that the nature, extent and quality of the services provided by the Adviser to the Master Fund are appropriate and consistent with the terms of the limited liability company agreement of the Master Fund, that the quality of those services is consistent with industry norms and that the Master Fund benefits from the Adviser’s management of the Master Fund investment program.

The Board noted that the performance of the Master Fund had been positive since inception and had less volatility than the equity markets, as measured by the S&P 500 Index.

The Board also concluded that the Adviser had sufficient personnel with the appropriate education and experience to serve the Master Fund effectively and has demonstrated its continuing ability to attract and retain qualified personnel. The Board noted that the Adviser is part of a larger investment advisory group that advises other funds and individual investors with respect to private equity investments and that relationship may make available to the Master Fund investment opportunities that would not be available to the Master Fund if the Adviser was not the Master Fund’s investment adviser.

Other Information (Unaudited) (continued)

Approval of Investment Management Agreement (continued)

The Board considered the anticipated costs of the services provided by the Adviser, and the compensation and benefits received by the Adviser in providing services to the Master Fund. The Board also reviewed the servicing fees paid to the Adviser or its affiliates by the Partners Group Private Equity, LLC and Partners Group Private Equity (TEI), LLC. The Board reviewed the financial statements of the Adviser’s parent, considered any direct or indirect revenues that could be received by affiliates of the Adviser, and concluded that the Adviser’s fees and profits derived from its relationship with the Master Fund in light of the Master Fund’s expenses were reasonable in relation to the nature and quality of the services provided, taking into account the fees charged by other advisers for managing comparable funds. The Board also concluded that the overall expense ratios of the Feeder Funds were reasonable, taking into account the size of the Feeder Funds and the quality of services provided by the Adviser.

The Board considered the extent to which economies of scale could be realized and whether fee levels would reflect those economies, noting that as the Master Fund grows, economies of scale would be realized.

The Board considered all factors and no one factor alone was deemed dispositive.

Conclusion

The Board determined that the information presented provided a sufficient basis upon which to approve the Agreement and that the compensation and other terms of the Agreement were in the best interests of the Master Fund and its Members.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

The Proxy Voting Policies are attached herewith.

PROXY VOTING POLICY

Partners Group Private Equity (Master Fund), LLC, 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 (the “Funds”) are clients of Partners Group (USA) Inc. (“the “Adviser”).  All proxy voting responsibilities of the Funds are performed by the Adviser, with the assistance of administrator of the Funds.

The Adviser shall vote the proxies appurtenant to all shares of corporate stock or ownership interest owned by each Fund for which it serves as adviser, and the Adviser shall vote said proxies strictly in accordance with the proxy voting policies submitted by that firm to and approved by the board of managers of the Funds.

The Adviser acts as fiduciary in relation to the portfolios of the Funds and any other clients that it may manage in the future and the assets entrusted by them to their management.  Where the assets placed in the Adviser’s care include shares of corporate stock or ownership interest, and except where the client has expressly reserved to itself or another party the duty to vote proxies, it is the Adviser’s duty as a fiduciary to vote all proxies relating to such shares.

The Adviser has an obligation to vote all proxies received from shares of corporate stock or ownership interest owned by its client accounts in the best interests of those clients.  In voting these proxies, the Adviser may not be motivated by, or subordinate the client’s interests to, its own objectives or those of persons or parties unrelated to the client.  The Adviser will exercise all appropriate and lawful care, skill, prudence and diligence in voting proxies, and shall vote all proxies relating to shares owned by its client accounts and received by the Adviser.  The Adviser shall not be responsible, however, for voting proxies that it does not receive in sufficient time to respond.

In order to carry out its responsibilities in regard to voting proxies, the Adviser must track all shareholder/interest holder meetings convened by companies whose shares are held in the Adviser client accounts, identify all issues presented to shareholder/interest holders at such meetings, formulate a principled position on each such issue and ensure that proxies pertaining to all shares owned in client accounts are voted in accordance with such determinations.

Investment advisers registered with the SEC, and which exercise voting authority with respect to client securities, are required by Rule 206(4)-6 of the Advisers Act of 1940, as amended, to (a) adopt and implement written policies and procedures that are reasonably designed to ensure that client securities are voted in the best interests of clients, which must include how an adviser addresses material conflicts that may arise between adviser’s interests and those of its clients; (b) to disclose to clients how they may obtain information from the adviser with respect to the voting of proxies for their securities; (c) to describe to clients a summary of its proxy voting policies and procedures and, upon request, furnish a copy to its clients; and (d) maintain certain records relating to the adviser’s proxy voting activities when the adviser does have proxy voting authority.

In addition, the Adviser may engage the services of an independent third party (“Proxy Firm”) to cast proxy votes according to the Adviser’s established guidelines.  The Proxy Firm will promptly notify the Adviser of any proxy issues that do not fall under the guidelines set forth below.  The Adviser does not believe that conflicts of interest will generally arise in connection with its proxy voting policies.

Generally, the Adviser views that proxy proposals can be grouped into six broad categories as follows:

I. Election of Board of Directors

· The Adviser will generally vote in support of management’s nominees for the board of directors; however, the Adviser may choose not to support management’s proposed board if circumstances warrant such consideration.

II. Appointment of Independent Auditors

· The Adviser will support the recommendation of the respective corporation’s board of directors.

III. Issues of Corporate Structure and Shareholder/Interest Holder Rights

· Proposals may originate from either management or shareholder/interest holders, and among other things, may request revisions to the corporate bylaws that will affect shareholder/interest holder ownership rights.  The Adviser does not generally support obstacles erected by corporations to prevent mergers or takeovers with the view that such actions may depress the corporation’s marketplace value.

· The Adviser supports the following types of corporate structure and shareholder/interest holder rights proposals:

o Management proposals for approval of stock/interest repurchase programs; stock splits (including reverse splits).

o Authorization to increase shares outstanding.

o The ability of shareholder/interest holders to vote on shareholder/interest holder rights plans (poison pills).

o Shareholder/interest holder rights to eliminate or remove supermajority provisions.

o Shareholder/interest holders’ rights to call special meetings and to act by written consent.

· the Adviser votes against management on the following items which have potentially substantial financial or best interest impact:

o Capitalization changes that add “blank check” classes of stock or classes that dilute the voting interests of existing shareholder/interest holders which are contrary to the best interest of existing shareholder/interest holders.

o Anti-takeover and related provisions that serve to prevent the majority of shareholder/interest holders from exercising their rights or effectively deter appropriate tender offers and other offers.

o Amendments to bylaws which would require super-majority shareholder/interest holder votes to pass or repeal certain provisions.

o Elimination of shareholder/interest holders’ right to call special meetings.

o Establishment of classified boards of directors.

o Reincorporation in a state which has more stringent anti-takeover and related provisions.

o Shareholder/interest holder rights plans that allow the board of directors to block appropriate offers to shareholder/interest holders or which trigger provisions preventing legitimate offers from proceeding.

o Excessive compensation.

o Change-in-control provisions in non-salary compensation plans, employment contracts, and severance agreements which benefit management and would be costly to shareholder/interest holders if triggered.

o Adjournment of meeting to solicit additional votes.

o “Other business as properly comes before the meeting” proposals which extend “blank check” powers to those acting as proxy.

o Proposals requesting re-election of insiders or affiliated directors who serve on audit, compensation, and nominating committees.

IV. Mergers and Acquisitions

· The Adviser evaluates mergers and acquisitions on a case-by-case basis.  The Adviser uses its discretion in order to maximize shareholder/interest holder value. The Adviser generally votes as follows.

o Against offers with potentially damaging consequences for minority shareholder/interest holders because of illiquid stock/interest, especially in some non-US markets.

o For offers that concur with index calculators’ treatment and our ability to meet our clients’ return objectives for passive funds.

o For proposals to restructure or liquidate closed end investment funds in which the secondary market price is substantially lower than the net asset value.

V. Executive and Director Equity-Based Compensation

· The Adviser is generally in favor of properly constructed equity-based compensation arrangements.  The Adviser will support proposals that provide management with the ability to implement compensation arrangements that are both fair and competitive.  However, the Adviser may oppose management proposals that could potentially significantly dilute shareholder/interest holders’ ownership interests in the corporation.

VI. Corporate Social and Policy Issues

· Proposals usually originate from shareholder/interest holders and may require a revision of certain business practices and policies.

· The Adviser believes, however, that typical business matters that directly or indirectly affect corporate profitability are primarily the responsibility of management.  The Adviser believes it is inappropriate to use client assets to address socio-political issues.  Therefore, social and policy issues reflected in shareholder/interest holder proposals should be subject to the approval of the corporation’s board of directors.

Conflicts

From time to time, the Adviser will review a proxy which presents a potential material conflict.  As a fiduciary to its clients, the Adviser takes these potential conflicts very seriously.  While the Adviser’s only goal in addressing any such potential conflict is to ensure that proxy votes are cast in the clients’ best interests and are not affected by the Adviser’s potential conflict, there are a number of courses the Adviser may take.  The final decision about which course to follow shall be made by the Adviser’s proxy committee.

When the matter falls clearly within one of the proposals enumerated above, casting a vote which simply follows the Adviser’s pre-determined policy would eliminate the Adviser’s discretion on the particular issue and hence avoid the conflict.

In other cases, where the matter presents a potential material conflict and is not clearly within one of the enumerated proposals, or is of such a nature that the Adviser believes more active involvement is necessary, the Adviser may employ the services of a Proxy Firm, wholly independent of the Adviser, and those parties involved in the proxy issue, to determine the appropriate vote.

Second, in certain situations the Adviser’s proxy committee may determine that the employment of a Proxy Firm is unfeasible, impractical or unnecessary.  In such situations, the proxy committee shall make a decision about the voting of the proxy.  The basis for the voting decision, including the basis for the determination that the decision is in the best interests of the Adviser’s clients, shall be formalized in writing.  As stated above, which action is appropriate in any given scenario would be the decision of the proxy committee in carrying out its duty to ensure that the proxies are voted in the clients’, and not the Adviser’s, best interests.

Potential Conflicts of Interests

Members of the Portfolio Management Team are involved in the management of other accounts, including proprietary accounts, separate accounts and other pooled investment vehicles.  Members of the Portfolio Management Team may manage separate accounts or other pooled investment vehicles that may have materially higher or different fee arrangements than the Fund and the Master Fund and may also be subject to performance-based fees.  The side-by-side management of these separate accounts and pooled investment vehicles may raise potential conflicts of interest relating to cross trading and the allocation of investment opportunities.

The Adviser has a fiduciary responsibility to manage all client accounts in a fair and equitable manner.  The Adviser seeks to provide best execution of all securities transactions and to allocate investments to client accounts in a fair and reasonable manner.  To this end, the Adviser has developed policies and procedures designed to mitigate and manage the potential conflicts of interest that may arise from side-by-side management.

(a)(3) Compensation Structure of Portfolio Manager(s) or Management Team Members

The Adviser is a wholly-owned subsidiary of Partners Group Holding AG (“Partners Group Holding”). Partners Group Holding is a stock corporation incorporated under Swiss law. The ownership structure is designed to motivate and retain employees. The firm employs over 750 people and is listed on the SIX Swiss Exchange (symbol: PGHN) with a major ownership by its partners and employees.

The Portfolio Management Team and other employees of the Adviser are compensated with a fixed base salary, which is paid on a monthly basis, additional employee benefits (pension fund, expense allowance, etc.), as well as a regular and/or special bonus, shares and/or options allocated under the Equity Participation Plan (“EPP”) and includes participation in the Management Carry Plan (“MCP”) for the year under review.

To assure strong alignment of interest between clients and shareholders and employees, the regular and/or special bonus, shares and/or options allocated under the EPP and MCP are subject to vesting periods. Any equity or option holder intending to leave the firm has the obligation to render his or her unvested interest back to the company, either in the form of equity shares or options depending upon the extent of ownership interest. As a result, the Adviser believes that members of the Portfolio Management Team have a strong interest to remain with the firm over the long term.
