Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited)

1. Organization

Partners Group Private Equity (Master Fund), LLC (the “Fund”) is a Delaware limited liability company which was organized 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 “Investment Company Act”), as a non-diversified, closed-end management investment company. The Fund is managed by Partners Group (USA) Inc. (the “Adviser”), an investment adviser registered under the Investment Advisers Act of 1940, as amended (the “Investment Advisers Act”) pursuant to an investment management agreement between the Fund and the Adviser (the “Investment Management Agreement”). The board of managers of the Fund (the “Board”) has oversight responsibility for the management and supervision of the business operations of the Fund. 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. The Fund’s investment objective is to seek attractive long-term capital appreciation by investing in a wholly owned diversified portfolio of private equity and debt investments. The Fund makes investments directly and through its wholly owned subsidiaries, Partners Group Private Equity (Subholding), LLC (the “Onshore Subsidiary”) and Partners Group Private Equity (Luxembourg) S.à r.l (the “Offshore Subsidiary”, and together with the Onshore Subsidiary, the “Subsidiaries”). The Board has oversight responsibility for the Fund’s investment in the Subsidiaries and the Fund’s role as sole member of the Subsidiaries.

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. Purchasers of Units become members of the Fund (“Members”).

Prior to January 1, 2017, the Fund operated as a master fund in a master-feeder structure that included Partners Group Private Equity, LLC and Partners Group Private Equity (TEI), LLC (the “Service Feeder Funds”) and Partners Group Private Equity (Institutional), LLC and Partners Group Private Equity (Institutional TEI), LLC (the “Institutional Feeder Funds” and together with the “Service Feeder Funds”, the “Feeder Funds”). As of December 31, 2016, the master-feeder structure was reorganized, resulting in a single fund, the Fund, with two separate classes of Units (the “Reorganization”). Prior to the Reorganization, the Feeder Funds owned all of the limited liability company interests in the Fund. As part of the Reorganization, all of the then outstanding interests of the Fund were converted into (i) Class A Units in the case of a Service Feeder Fund and (ii) Class I Units in the case of an Institutional Feeder Fund. The financial statements (including the financial highlights) of the Feeder Funds, and other information about the Feeder Funds, can be obtained on the SEC’s website (http://www.sec.gov). The address of the SEC’s internet site is provided solely for the information of prospective investors and is not intended to be an active link. Following the Reorganization on December 31, 2016 at 11:59pm EST, each member of the Feeder Funds became a Member of the Fund. Effective January 1, 2017, the Fund elected to be treated for U.S. federal income tax purposes and intends to qualify annually, as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Reorganization constituted a tax-free reorganization of the Fund under the Code.

The Fund offers two separate classes of Units designated as Class A Units (the “Class A Units”) and Class I Units (the “Class I Units”). While the Fund presently intends to offer only two classes of Units, in the future it may offer additional classes of Units. The Class A Units and the Class I Units have, and each additional class of Units issued by the Fund, if any, will have different characteristics, particularly in terms of the sales charges that Members in any such class bear, and the distribution and service fees that are charged to such class. The Fund has received an exemptive order from the SEC with respect to the Fund’s multi-class structure. Class I is deemed to be the accounting survivor of the Reorganization.

Each class represents a pro-rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of Units based on the relative net assets of each class to the total net assets of the Fund. Each class of Units differs in its distribution and service plan, if any, and certain other class-specific expenses.

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 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”).

19

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

b. Valuation of Investments

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

The Adviser estimates the fair value of the Fund’s Private Equity Investments in conformity with U.S. GAAP and the Fund’s valuation procedures (the “Valuation Procedures”). The Valuation Procedures, which have been approved by the Board, require evaluation of all relevant factors reasonably available to the Adviser at the time the Fund’s Private Equity Investments are valued. The inputs or methodologies used for valuing the 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 the Fund’s non-traded Direct Investments in accordance with the Valuation Procedures, the Adviser uses a variety of methods such as the latest round of financing, earnings and multiple analysis, discounted cash flow and market data from third party pricing services, 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. Because of the inherent uncertainty of estimates, fair value determinations -based on estimates may differ from the values that would have been used had a ready market for the securities existed, and the differences could be material.

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 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 of estimates, fair value determinations-based on estimates may differ from the values that would have been used had a ready market for the securities existed, and the differences could be material.

For each class of investment that includes investments that can never be redeemed with the investees, the Fund expects to receive distributions through the liquidation of the underlying assets of the investees at the end of the partnership term.

Daily Traded Investments

The Fund values its investments that are traded on a particular day (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 of the relevant determination. 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.

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

The Valuation Procedures are implemented by the Adviser and State Street Bank and Trust Company, as the Fund’s administer (the “Administrator”). Both the Adviser and the Administrator report to the Board. For third-party information, the Administrator monitors and reviews the methodologies of the various pricing services employed by the Fund. The Adviser employs valuation techniques for Private Equity Investments held by the Fund, which include discounted cash flow methods and market comparables. The Adviser and one or more of its affiliates act as investment advisers to clients other than the Fund. When clients other than the Fund also hold Private Equity Investments held by the Fund, the Adviser values such Private Equity Investments in consultation with its affiliates.

The valuations attributed to Private Equity Investments held by the Fund and other clients of the Adviser might differ as a result of differences in accounting, regulatory and other factors applicable to the Fund and the other clients.

c. Cash and Cash Equivalents

Pending investment in Private Equity Investments and in order to maintain liquidity, the Fund holds cash, including amounts held in foreign currencies and short-term interest bearing deposit accounts. At times, those amounts may exceed applicable 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.

d. Foreign Currency Translation

The books and records of the 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 September 30, 2018, the Fund’s investments denominated in foreign currencies were as follows:

Currency	Number of investments
Australian Dollars	8
Brazilian Reals	1
Canadian Dollars	4
Danish Krone	3
Euros	110
Hong Kong Dollars	2
Indian Rupees	2
Japanese Yen	2
Pound Sterling	20
Singapore Dollar	2
Swedish Krona	1
Swiss Francs	1

The 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 Adviser may cause the Fund to enter forward foreign currency exchange contracts as a way of managing foreign exchange rate risk. These contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date may be entered into either as a hedge or as a cross hedge against either specific transactions or portfolio positions. The objective of the Fund’s foreign currency hedging transactions is to reduce the risk that the U.S. Dollar value of the 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.

21

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

During the six months ended September 30, 2018, the Fund entered into 31 long forward foreign currency exchange contracts. As disclosed in the Consolidated Statement of Assets and Liabilities, the Fund had $3,417,405 in unrealized appreciation and $0 in unrealized depreciation on forward foreign currency exchange contracts. As disclosed in the Consolidated Statement of Operations, the Fund had $31,856,970 in net realized gains and $2,030,520 change in net unrealized appreciation (depreciation) on forward foreign currency contracts. The outstanding forward foreign currency exchange contract amounts at September 30, 2018 are representative of contract amounts during the period.

f. Investment Income

The Fund records distributions of cash or in-kind securities on a Private Equity Investment at fair value based on the information contained in notices provided to the Fund when distributions on a Private Equity Investment are received. Thus, the Fund recognizes within the Consolidated Statement of Operations its share of realized gains or (losses) and the Fund’s share of net investment income or (loss) based upon information received about distributions on Private Equity Investments. Unrealized appreciation (depreciation) on investments within the Consolidated Statement of Operations includes the Fund’s share of unrealized gains and losses, realized undistributed gains/losses, and the Fund’s share of undistributed net investment income or (loss) on Private Equity Investments for the relevant period.

For certain Direct Investments, the Fund accounts for particular income received as other income and transaction income. The other income includes transfer fees, amendment fees, unfunded fees and any other income which is not categorized as an interest income. The transaction income is an extraordinary income for certain Direct Investments including break-up fees, directors’ fees, financial advisory fees, topping fees, investment banking fees, monitoring fees, organizational fees, syndication fees, and any other fees payable to the Fund with respect to any Direct Investments or unconsummated transactions.

g. Fund Expenses

The Fund bears all expenses incurred in the business of the Fund on an accrual basis, including, but not limited to, the following: all costs and expenses related to portfolio transactions and positions for the Fund’s account; legal fees; accounting, auditing, and tax preparation fees; custodial fees; fees for line of credit; 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 Secondary Investments. 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

The Fund recognizes tax positions in its consolidated financial statements only when it is more likely than not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized upon settlement. The Fund reports any interest expense related to income tax matters in income tax expense, and any income tax penalties under expenses in the Consolidated Statements of Operations.

The Fund’s tax positions have been reviewed based on applicable statutes of limitation for tax assessments, which may vary by jurisdiction, and based on such review, the Fund has concluded that no additional provision for income tax is required in the Fund’s consolidated financial statements. The Fund is subject to potential examination by certain taxing authorities in various jurisdictions. The Fund’s tax positions are subject to ongoing interpretation of laws and regulations by taxing authorities.

Prior to January 1, 2017, for U.S. federal income tax purposes, the Fund was treated as a partnership, and each Member of the Fund (i.e., each Feeder Fund) was 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 were 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.

22

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

As noted above, effective December 31, 2016, the Fund filed an election with the Internal Revenue Service to be treated as an association taxable as a corporation for U.S. federal income tax purposes. Furthermore, effective January 1, 2017, the Fund elected to be treated for U.S. federal income tax purposes and intends to qualify annually, as a RIC under the Code. If the Fund were to fail to meet the requirements of Subchapter M of the Code to qualify as a RIC, and if the Fund were ineligible to or otherwise were not to cure such failure, the Fund would be subject to tax on its taxable income at corporate rates, whether or not distributed to Members, and all distributions out of earnings and profits would be taxable to Members as ordinary income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before re-qualifying as a RIC that is accorded special tax treatment under Subchapter M of the Code. The Fund intends to comply with the requirements under Subchapter M of the Code and to distribute substantially all of its taxable income and gains to Members and to meet certain diversification and income requirements with respect to its investments. The Onshore Subsidiary will continue to be treated as an association taxable as a corporation for U.S. federal income tax purposes. The Offshore Subsidiary will continue to be treated as an entity disregarded as separate from its sole owner, the Fund, for U.S. federal income tax purposes. As part of the process of preparing its consolidated financial statements, the Onshore Subsidiary is required to account for its estimate of income taxes for Federal and State purposes through the establishment of a deferred tax asset or liability. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. To the extent the Onshore Subsidiary has a deferred tax asset, consideration is given to whether or not a valuation allowance is required. The Offshore Subsidiary is not subject to U.S. federal and state income taxes.

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, 2018, the tax years from the year 2015 forward remain subject to examination by the major tax jurisdictions under the statute of limitations.

The Fund reclassified $(106,610) from undistributed net investment income, $(12,819,949) of accumulated net realized gain (loss) on investments, forward foreign currency contracts and $0 of accumulated net unrealized appreciation on investments, forward foreign currency contracts and foreign currency translation, to paid-in capital during the year ended March 31, 2018. The reclassification reflected an adjustment to paid-in capital due to the change for federal income tax purposes in taxation as a partnership to taxation as a RIC.

There were no current or deferred taxes recognized for the Onshore Subsidiary and Offshore Subsidiary.

j. Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the 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, Consolidated Statement of Assets and Liabilities, Consolidated Statement of Operations, Consolidated Statements of Changes in Net Assets, Consolidated Statement of Changes in Members’ Equity, Consolidated Statement of Cash Flows and Consolidated Financial Highlights of the Fund include the accounts of the Subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

l. Disclosures about Offsetting Assets and Liabilities

The 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.

23

Partners Group Private Equity (Master Fund), LLC

(a Delaware Limited Liability Company)

Notes to Consolidated Financial Statements – September 30, 2018 (Unaudited) (continued)

2. Significant Accounting Policies (continued)

For financial reporting purposes, the Fund does not offset derivative assets and liabilities that are subject to Netting Agreements (“MNA”) or similar arrangements in the Consolidated Statement of Assets and Liabilities. The Fund has adopted the disclosure requirements on offsetting in the following table which presents the Fund’s derivative assets by type, net of amounts available for offset under a MNA and net of the related collateral received by the Fund as of September 30, 2018:

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 Amount1
Barclays Capital	$	3,417,405	$	—	$	—	$	—	$	3,417,405

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

m. Recently Adopted Accounting Pronouncement

As of September 30, 2018, there are no recent accounting pronouncements under consideration by the Fund.

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 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 date, the mean between the closing bid and ask prices on such date. The Fund does not apply a blockage discount to the quoted price for these investments, even in situations where the 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 are equity and debt 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 investment operates, comparable market transactions, 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, brokers quotes as well as discounted cash flow analysis.

3. Fair Value Measurements (continued)

The following table presents the Fund’s investments at September 30, 2018 measured at fair value. Due to the inherent uncertainty of estimates, fair value determinations based on estimates may materially differ from the values that would have been used had a ready market for the securities existed.

The following is a summary of the Fund’s investments classified in the fair value hierarchy as of September 30, 2018:

Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur. For the six months ended September 30, 2018, there were no transfers from Level 3 to Level 2.

The amount of the net change in unrealized appreciation for the six months ended September 30, 2018 relating to investments in Level 3 assets still held at September 30, 2018 is $70,496,147, which is included as a component of net change in accumulated unrealized depreciation on investments on the Consolidated Statement of Operations.

Changes in inputs or methodologies used for valuing investments may result in a transfer in or out of levels within the fair value hierarchy. The inputs or methodologies used for valuing investments may not necessarily be an indication of the risk associated with investing in those investments. Transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period.

^* For the purposes of the tables above: “Direct Investments” are private investments directly into the equity or debt of selected operating companies, often together with the management of the investee operating company. Primary Investments are investments in newly established private equity partnerships where underlying portfolio companies are generally not known as of the time of investment. Secondary Investments involve acquiring single or portfolios of assets on the secondary market. Secondary Investments are Private Equity Fund Investments generally acquired in the secondary market. Notwithstanding the foregoing, if the Fund reasonably determines that the strict application of the above definitions would not reflect the economic substance of any Investment, the Fund may re-classify such Investment as it deems appropriate.

3. Fair Value Measurements (continued)

The following is a summary of quantitative information about significant unobservable valuation inputs approved by the Adviser for Level 3 Fair Value Measurements for investments held as of September 30, 2018:

Type of Security	Fair Value at September 30, 2018 (000’s)*			Valuation Technique(s)	Unobservable Input	Range (weighted average)
Direct Investments:
Direct Equity	$	1,090,694		Market comparable companies	Enterprise value to EBITDA multiple	6.68 x – 17.80 x (12.99 x)
		70,073		Market comparable companies	Price to book ratio	5.50 x -5.50 x (5.50 x)
		1,113		Market comparable companies	Enterprise value to sales multiple	0.70 x - 2.25 x (2.00 x)
		5,251		Reported fair value	Reported fair value	n/a - n/a (n/a)
		2,563		Exit price	Recent transaction price	n/a - n/a (n/a)
		330,532		Recent financing	Recent transaction price	n/a - n/a (n/a)
Direct Debt	$	5,453		Market comparable companies	Enterprise value to EBITDA multiple	7.56 x – 7.56 x (7.56 x)
		301,350		Discounted cash flow	Discount factor	5.06% - 14.43% (8.68%)
		459,584		Broker quotes	Indicative quotes for an inactive market	n/a - n/a (n/a)
		38,936		Recent financing	Recent transaction price	n/a - n/a (n/a)
Primary and Secondary Investments	$	657,488		Adjusted reported net asset value	Reported net asset value	n/a - n/a (n/a)
		(2,700	)	Adjusted reported net asset value	Fair value adjustments	n/a - n/a (n/a)

^* Level 3 fair value includes accrued interest.

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 Fund arrives at a fair value through the use of 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. Revolving Credit Agreement

Effective February 2, 2016, the Fund entered into a secured, committed multicurrency revolving line of credit (“LOC”) facility with Lloyds Bank plc and The Royal Bank of Scotland plc in the aggregate maximum principal amount of $150,000,000. The Fund anticipates that this line of credit facility will be primarily used for working capital requirements and for financing investments and funding associated costs and expenses. The Fund will incur additional interest and other expenses with respect to the use of this and other future line of credit facilities. Borrowings are charged a rate of interest per annum which is the aggregate of the applicable margin and London Interbank Offered Rate (“LIBOR”) or, in relation to any loan in Euros, the Euro Interbank Offered Rate (“EURIBOR”), and a commitment fee of 1.20% per annum on the daily unused portion. For the six months ended September 30, 2018, the Fund did not utilize this LOC and paid no interest on borrowings. There were no outstanding borrowings at September 30, 2018. In addition to the Commitment fees of 1.20% the Fund pays Arrangement fees (1.15% of the total commitment), Agency fees of $25,000 per annum, Monitoring fees of $25,000 per annum and Trustee fees of $15,000 per annum. The Arrangement fees are disclosed as an asset amortized over the life of the LOC arrangement and expensed monthly on the Statement of Operations as a Line of Credit fees. The arrangement fees are paid in several instalments with the first payment due on the date of the Facility Agreement followed by the first and second anniversary of the date of the contract.

5. Distributions/Allocation of Members’ Capital

Until December 31, 2016, net profits or net losses of the Fund for each Allocation Period (as defined below) were allocated among and credited to or debited against the capital accounts of the Members (i.e., each Feeder Fund). 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 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.

As of January 1, 2017, the Fund contemplates declaring at least annually as dividends all or substantially all of its investment company taxable income. From time to time, the Fund may also pay special interim distributions in the form of cash or Units at the discretion of the Board. Unless Members elect to receive distributions in the form of cash, the Fund intends to make its ordinary distributions in the form of additional Units under a dividend reinvestment plan. Any distributions reinvested will nevertheless remain taxable to Members that are U.S. persons.

From and after January 1, 2017, the Incentive Allocation has been replaced by an “Incentive Fee” having the same economic effect on Members as the Incentive Allocation. See discussion in Note 7.

6. Unit Transactions/Subscription and Repurchase of Units

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

Pursuant to the conditions of an exemptive order issued by the SEC, and in compliance with Rule 12b-1 under the Investment Company Act, the Fund has adopted a Distribution and Service Plan with respect to the Class A Units (the “Distribution Plan”). The Distribution Plan allows the Fund to pay distribution fees for the promotion and distribution of its Class A Units and the provision of personal services to holders of Class A Units. Under the Distribution Plan, the Fund may pay to the Fund’s placement agent other qualified recipients as compensation up to 0.70% on an annualized basis of the value of the Fund’s net asset attributable to Class A Units (the “Distribution Fee”). Payment of the Distribution Fee is governed by the Distribution Plan. The Distribution Fee is paid out of the Fund’s assets and decreases the net profits or increases the net losses of the Fund solely with respect to Class A Units. Class I Units are not subject to the Distribution Plan or the Distribution Fee and do not bear any expenses associated therewith. In addition, under the Distribution Plan, subscriptions for Class A Units may be subject to a placement fee (the “Placement Fee”) of up to 3.50% of the subscription amount. No Placement Fee may be charged without the consent of the placement agent.

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 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 Fund conduct quarterly repurchase offers for Units having an aggregate value of no more than 5% of the Fund’s net assets on or about each January 1st, April 1st, July 1st and October 1st. A 2.00% early repurchase fee (the “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. For all Units received in connection with the Reorganization, the prior holding period is tacked.

7. Management Fees, Incentive Fee and Fees and Expenses of Managers

Under the terms of the Investment Management Agreement the Adviser is responsible for providing day-to-day investment management and certain other services to the Fund, subject to the ultimate supervision of and subject to any policies established by the Board. Accordingly, the Adviser is responsible for developing, implementing and supervising the Fund’s investment program. Until December 31, 2016, in consideration for its investment management services under the Investment Management Agreement the Fund paid 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 Fund’s net asset value and (ii) the Fund’s net asset value less cash and cash equivalents plus the total of all commitments made by the Fund that have not yet been drawn for investment.

Effective with the Reorganization on January 1, 2017 the percentage in the above formula was increased from 1.25 to 1.5%. However, the Investment Management Agreement provides that in no event will the management fee exceed 1.75% as a percentage of the Fund’s net asset value. For the six months ended September 30, 2018, the Fund accrued $28,404,842 in management fees to the Adviser.

In addition, until December 31, 2016, 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 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) was 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 Fund (the “Incentive Allocation Account”). The Incentive Allocation Account was maintained solely for the purpose of being allocated the Incentive Allocation and thus, the Incentive Allocation Account did not participate in the net profits or losses of the Fund.

7. Management Fees, Incentive Fee and Expenses of Managers (continued)

Effective with the Reorganization January 1, 2017, at the end of each calendar quarter (and at certain other times), the Adviser will be entitled to receive an amount (the “Incentive Fee”) equal to 10% of the excess, if any, of (i) the net profits of the Fund for the relevant period over (ii) the then balance, if any, of the New Loss Recovery Account (as defined below). For the purposes of the Incentive Fee, the term “net profits” shall mean the amount by which the net asset value of the Fund on the last day of the relevant period exceeds the net asset value of the Fund as of the commencement of the same period, including any net change in unrealized appreciation or depreciation of investments and realized income and gains or losses and expenses. The Fund maintains a memorandum account (the “New Loss Recovery Account”), which had an initial balance of zero and will be (i) increased upon the close of each calendar quarter of the Fund by the amount of the net losses of the Fund for the quarter, and (ii) decreased (but not below zero) upon the close of each calendar quarter by the amount of the net profits of the Fund for the quarter. Members will benefit from the New Loss Recovery Account in proportion to their holdings of Units. For the six months ended September 30, 2018, the Fund accrued $20,866,268 in Incentive Fees to the Adviser.

In consideration of the services rendered by each Manager who was not an “interested person” of the Fund, as defined by the Investment Company Act (each, an “Independent Manager”), the Fund pays each Independent Manager an annual fee of $80,667. The Managers do not receive any pension or retirement benefits. The Fund also reimburses the expenses of the Independent Managers in connection with their services as Managers.

8. Affiliated Investments

Under Section 2(a)(3) of the Investment Company Act, a portfolio company is defined as “affiliated” if a Fund owns five percent or more of its outstanding voting securities. The Fund held at least five percent of the outstanding voting securities of the following companies as of September 30, 2018:

⁽¹⁾ Gross additions may include increases in the cost basis of investments resulting from new portfolio investments, the accretion of discounts and the exchange of one or more existing securities for one or more new securities.

⁽²⁾ Gross reductions may include decreases in the cost basis of investments resulting from principal collections related to investment repayments or sales and the exchange of one or more existing securities for one or more new securities.

⁽³⁾ Investment does not issue shares.

^* The financial statements for the period ended March 31, 2018 incorrectly omitted this investment as an affiliate. Fund management has evaluated the impact of this omission on the previously issued financial statements as of and for the year ended March 31, 2018 taken as a whole and concluded that such financial statements were not materially misstated. However, in order to correctly present affiliated investments, the above table has been revised to appropriately reflect the investment as an affiliated investment as of March 31, 2018. The March 31, 2018 financial statements will be revised to correct for this omission the next time filed.

9. Accounting and Administration Agreement

The Administrator serves as administrator and accounting agent to the Fund and provides certain accounting, record keeping and investor related services pursuant to an Accounting and Administration Agreement between the Fund and the Administrator. 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 months ended September 30, 2018, the Fund accumulated $1,547,875 in administration and accounting fees.

10. Investment Transactions

Total purchases of investments for the six months ended September 30, 2018 amounted to $659,299,030. Total distribution proceeds from sale, redemption, or other disposition of investments for the six months ended September 30, 2018 amounted to $329,510,820. The cost of investments for U.S. federal income tax purposes is adjusted for items of taxable income allocated to the Fund from such investments. The Fund relies upon actual and estimated tax information provided by the managers of the investments as to the amounts of taxable income allocated to the Fund as of September 30, 2018.

11. Indemnification

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

12. Commitments

As of September 30, 2018, the Fund had funded $3,952,894,847 or 83.1% of the $4,756,289,303 of its total commitments to Private Equity Investments. With respect to its (i) Direct Investments it had funded $2,913,891,231 of $2,999,667,572 in total commitments, (ii) Secondary Investments it had funded $611,528,823 of $637,872,156 in total commitments, and (iii) Primary Investments it had funded $427,474,793 of $1,118,749,575 in total commitments, in each case, as of September 30, 2018.

13. Risk Factors

An investment in the 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 Fund invests substantially all of its available capital in Private Equity Investments. Typically, these investments are in restricted securities that are not traded in public markets and subject to substantial holding periods, so that the Fund may not be able to resell some of its holdings for extended periods, which may be several years. The 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 Fund. The Fund’s investments are also subject to the risk associated with investing in private equity securities. The investments in private securities are illiquid, can be subject to various restrictions on resale, and there can be no assurance that the 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. As a consequence 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.

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

Fund Expenses (Unaudited)

Example: As a Fund Member, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase; and (2) ongoing costs, including management fees; distribution and/or service fees (12b-1 fees); and other Fund expenses. This Example is intended to help you understand your ongoing costs (in US Dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds. The actual and hypothetical expense Examples are based on an investment of $1,000 invested at the beginning of a six month period and held through the year ended September 30, 2018.

Actual Expenses: The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes: The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the Members reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) on redemption/exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value (04/01/18)		Ending Account Value (09/30/18)		Expenses Paid During the Period*		Annualized Net Expense Ratio**
Actual
Class A Units	$	1,000.00	$	1,050.20	$	20.51		3.99	%
Class I Units	$	1,000.00	$	1,053.90	$	16.89		3.28	%

	Beginning Account Value (04/01/18)		Ending Account Value (09/30/18)		Expenses Paid During the Period*		Annualized Net Expense Ratio**
Hypothetical (5% annual return before expenses)
Class A Units	$	1,000.00	$	1,005.10	$	20.06		3.99	%
Class I Units	$	1,000.00	$	1,008.60	$	16.52		3.28	%

^* Expenses are calculated using to the Fund’s annualized expense ratio for the indicated Class, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per unit determined at the opening of business on April 1, 2018.

^** Annualized ratio of expenses to average net assets for the period from April 1, 2018 through September 30, 2018. The expense ratio includes the effect of expenses waived or reimbursed by the Adviser.

(b)(1) Identification of Portfolio Manager(s) or Management Team Members and Description of Role of Portfolio Manager(s) or Management Team Members

Effective July 1, 2018, Mr. Adam Howarth was appointed as a portfolio manager for the registrant.

Name of Investment Committee Member	Title	Length of Time of Service to the Fund	Business Experience During the Past 5 Years	Role of Investment Committee Member
Adam Howarth	Managing Director	Since 2009*	Managing Director, Partners Group (2013-Present); Partners Group (2007-Present).	Portfolio Management

* Mr. Howarth served as a portfolio manager for the registrant from 2009-2011 and as deputy portfolio manager from 2014-2018.

(b)(2) Other Accounts Managed by Portfolio Manager(s) or Management Team Member and Potential Conflicts of Interest

As of September 30, 2018, Mr. Howarth was primarily responsible for the day-to-day portfolio management of the following accounts:

Number of Other Accounts Managed and Total Value of Assets by Account Type for Which There is No Performance-Based Fee			Number of Other Accounts and Total Value of Assets for Which Advisory Fee is Performance-Based
Registered investment companies	Other pooled investment vehicles	Other accounts	Registered investment companies	Other pooled investment vehicles	Other accounts
Zero accounts	Zero accounts	Zero accounts	One registered investment company with a value of $65.984 million	Four pooled investment vehicles with a value of $262.003 million	Twenty-eight accounts with a value of $2.353 billion

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 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.

(b)(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”) and an affiliate of Partners Group AG, the principal operating subsidiary of Partners Group Holding. Partners Group Holding is a listed company with major ownership by its employees. The ownership structure is designed to motivate and retain employees.

The Portfolio Management Team and other employees of the Adviser are compensated with a fixed annual salary, which is typically supplemented by an annual bonus based on individual and team based performance. Key professionals, including the Portfolio Management Team, are additionally compensated through equity participation in Partners Group Holding.

This equity ownership is structured in a manner designed to provide for long-term continuity. Accordingly, the vesting parameters of equity incentives are rather stringent. 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.

(b)(4) Disclosure of Securities Ownership

As of September 30, 2018, Mr. Howarth did not beneficially own any units of the registrant.
