Dear TEF Partners:

In a year where most major asset classes struggled, 2015 was a relatively good year for The Endowment Fund (the “Fund”)¹ and for the core alternative strategies in which it invests. Thank you for the continued support with your investment in The Endowment Fund. Similar to past shareholder letters, we will provide an update on the performance of the Fund as well as give Shareholders a sense of our views of the environment for the Fund and its strategies in 2016 and beyond.

The goal of The Endowment Fund is to generate a high-quality return stream that targets approximately half the historical volatility of equities (8% target standard deviation) with very low correlation to traditional stocks and bonds.

Investment Performance in 2015

The Endowment Registered Fund returned 2.12% in 2015, which outpaced the HFRI FOF Composite Index by 2.46% (HFRI Fund of Funds Composite was -0.34% for 2015). The year’s performance was driven by the second and third quarters with marks of 2.66% and 1.20%, respectively. Both Q1 and Q4 detracted from the year’s performance with numbers of -0.40% for Q1 and -1.32% for Q4.

The mid-year positive performance is largely attributed to the Private Equity asset class, as it performed well with increases in fair value within the venture capital, growth equity, and buyout sub-asset classes. There were also two notable exits from the venture capital portfolio that contributed to the Fund’s performance. The Private Equity portfolio added 4.14% to the overall portfolio for the year (as a reminder, performance contribution is calculated by multiplying the return of the asset class by its allocation within the portfolio).^

The Fund’s most consistent performer for the year was the Relative Value asset class. The portfolio contributed positively to the Fund’s overall performance in 10 of the 12 months this year, with an overall contribution to Fund performance of 1.34%. In an otherwise lackluster year for public equity markets; the two largest positions in the portfolio each had gains in excess of 12.5% on the year.

¹ The Endowment Fund has a variety of feeders, which all feed into a single “master” fund called The Endowment Master Fund, L.P. Each “feeder” fund has different expense ratios, which provide for slightly different returns from one “feeder” fund to the next. Accordingly, unless otherwise specified, the returns outlined herein are those of The Endowment Registered Fund, L.P., which is the largest “feeder” fund in The Endowment Fund complex. Your returns may vary, based on the feeder in which you invest and the timing of your investment. Please consult your capital account statement for the exact returns of your investment.

^ Portfolio composition is subject to change.

Despite being the smallest asset class in the portfolio, the Event-Driven asset class contributed a meaningful 0.70% to overall performance. This was largely due to a single manager that had exposure to a wireless broadband company that went bankrupt in 2012. After disappointing news in 2014 of a proposed restructuring plan that would essentially wipe out the manager’s ownership in the company, the investment was marked down. Early in 2015, we received news of a valuation reversal based on increased probability of a favorable outcome for the manager as well as a higher-than-expected valuation for another piece of spectrum the company owns.^

The Global Macro and Trading and Energy asset classes detracted on the year with performance of -2.64% and -1.33%, respectively. The continued decline in oil prices paired with struggles across the majority of commodity markets negatively impacted the performance of these asset classes. With that said, we believe the recent turmoil in the energy sector may present unique distressed opportunities in the years ahead.

While the Real Estate asset class was essentially flat for the year, we did see an increase in the amount of volatility within the portfolio. As a group, domestically focused GPs contributed positively to asset class’ overall performance. However, GPs with an investment focus in foreign markets had a difficult year, most notably those that were heavily invested in Brazil. We believe a strong dollar and a collapse in commodity markets negatively impacted many of the emerging market economies, which in turn, affected their respective real estate markets.

Private Equity includes performance from prior periods received after the prior month end. Past performance is not indicative of future results. Performance is based on total return.

Economic Overview

The S&P 500 generated a +1.37% return for 2015, marking the worst performance year since 2008. While the S&P 500 was fairly flat, we did see an increase in volatility across several segments of the market. Consumer discretionary stocks led the market with a gain of 10.11% for the year, while energy stocks brought up the rear with a -21.12% return. The price of oil continued its downward trend from 2014 as the price of West Texas Intermediate Crude Oil closed out 2015 at $37.04/bbl. The dollar meaningfully strengthened relative to most all other currencies. Rates remain suppressed in spite of the Federal Reserve initiating their long awaited rate hike. And the Chinese market had a volatile year as we saw a tremendous run up in Chinese A shares in the first half of the year, followed by a sharp decline in the latter half of the year.

^ Portfolio Composition is subject to change.

Below are several themes we’ve noticed throughout 2015 that we believe will impact markets in 2016:

• The headwind of a rising dollar: The U.S. Dollar strengthened during 2015 against developed currencies like the Euro, the Pound, the Yen, etc., with an even further appreciation against almost all emerging market currencies. We believe this will continue to diminish the competitiveness of U.S. corporations and will further challenge emerging market companies who externally finance their operations in U.S. dollars. The Federal Reserves’ tightening of short-term interest rates may likely add further strength to the dollar as well.

• Decline in interest rates: The overall decline in both nominal and real interest rates continues to paint a troubling picture of global deflationary pressure and low capital market returns.

• Continued decline in energy prices: The sharp decline in energy prices witnessed last year has created stress in both stock and bond markets. We believe many energy companies will be forced to restructure balance sheets and consider strategic options as their asset bases have eroded. We believe this will present unique distressed opportunities in 2016 and beyond.

• Slowing demand in China: Coupled with the decline in natural resources noted above, slowing demand from China represents meaningful challenges for a number of emerging market economies. Nearly all emerging market economies have shifted from accumulating to dispersing foreign exchange reserves.

• Global debt: Global debt remains at record highs and exceeds 2007 levels that resulted in the financial crisis of 2008, while the methods for dealing with over-indebtedness – increasing taxes, decreasing expenditures, growing out of it, inflating out of it or restructuring it – seem either unpalatable or unattainable.

As can be gleaned from the bullets above, we believe we enter 2016 with a number of headwinds facing the global economy. With that said, we believe that The Endowment Fund is well positioned because of the diversified nature of its private equity and hedge fund portfolios. We believe that emphasizing results that are driven by skill, diversification and premia like illiquidity are important to generating full cycle results that are not as sensitive to capital market returns, for which we have more limited potential return expectations on a going-forward basis. Further, we believe that maintaining investment in a mature private investments portfolio, which The Endowment Fund allows, may avoid many of the risks and pitfalls of new investments in multi-asset private portfolios. Lastly, we believe that providing access to exclusive top-tier hedge funds and co-investment opportunities allows the delivery of focused, diversifying exposures to core alternatives that are absolute return in nature and not as dependent on the rising and falling waves of the broader market.

We thank you for your continued support. If you have any questions, please do not hesitate to call our service desk at 1-800-725-9456.

Kindest Regards,

Endowment Advisers, L.P.²

Notes to Financial Statements

December 31, 2015

(1) ORGANIZATION

The Endowment Institutional TEI Fund W, L.P. (the “Institutional TEI W Fund”), a Delaware limited partnership registered under the Investment Company Act of 1940, as amended (the “1940 Act”), commenced operations on January 1, 2011, as a non-diversified, closed-end management investment company. The Institutional TEI W Fund was created to serve as a feeder fund for The Endowment Institutional TEI Fund W, Ltd. (the “Offshore Institutional W Fund”), which in turn is a feeder fund for The Endowment Master Fund, L.P. (the “Master Fund”). For convenience, reference to the Institutional TEI W Fund may include the Offshore Institutional W Fund and Master Fund, as the context requires.

The Institutional TEI W Fund’s investment objective is to preserve capital and to generate consistent long- term appreciation and returns across a market cycle (which is estimated to be five to seven years). The Institutional TEI W Fund pursues its investment objective by investing substantially all of its assets in the Offshore Institutional W Fund, which in turn invests substantially all of its assets in the Master Fund, which has the same investment objectives as the Offshore Institutional W Fund and the Institutional TEI W Fund. The Master Fund invests its assets in investment vehicles including, but not limited to, limited partnerships, limited liability companies, hedge funds, offshore corporations and other foreign investment vehicles (collectively, the “Investment Funds”), registered investment companies (including exchange-traded funds) and direct investments in marketable securities and derivative instruments. The Master Fund’s financial statements, Schedule of Investments and notes to financial statements, included elsewhere in this report, should be read in conjunction with this report. The Offshore Institutional W Fund serves solely as an intermediary for the Institutional TEI W Fund’s investment in the Master Fund. The percentage of the Master Fund’s partnership interests indirectly owned by the Institutional TEI W Fund on December 31, 2015, was 1.20%.

The Endowment Fund GP, L.P., a Delaware limited partnership, serves as the general partner of the Institutional TEI W Fund (the “General Partner”). To the fullest extent permitted by applicable law, the General Partner has irrevocably delegated to a board of directors (the “Board” and each member a “Director”) its rights and powers to monitor and oversee the business affairs of the Institutional TEI W Fund, including the complete and exclusive authority to oversee and establish policies regarding the management, conduct, and operation of the Institutional TEI W Fund’s business. A majority of the members of the Board are independent of the General Partner and its management. To the extent permitted by applicable law, the Board may delegate any of its rights, powers and authority to, among others, the officers of the Institutional TEI W Fund, the Adviser, or any committee of the Board.

The Board is authorized to engage an investment adviser and it has selected Endowment Advisers, L.P. (the “Adviser”), to manage the Institutional TEI W Fund’s portfolio and operations, pursuant to an investment management agreement (the “Investment Management Agreement”). The Adviser is a Delaware limited partnership that is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Management Agreement, the Adviser is responsible for the establishment of an investment committee, which is responsible for developing, implementing, and supervising the Institutional TEI W Fund’s investment program subject to the ultimate supervision of the Board. In addition to investment advisory services, the Adviser also functions as the servicing agent of the Institutional TEI W Fund (the “Servicing Agent”) and as such provides or procures investor services and administrative assistance for the Institutional TEI W Fund. The Adviser can delegate all or a portion of its duties as Servicing Agent to other parties, who would in turn act as sub-servicing agents.

December 31, 2015

Under the Institutional TEI W Fund’s organizational documents, the Institutional TEI W Fund’s officers and Directors are indemnified against certain liabilities arising out of the performance of their duties to the Institutional TEI W Fund. In the normal course of business, the Institutional TEI W Fund enters into contracts with service providers, which also provide for indemnifications by the Institutional TEI W Fund. The Institutional TEI W Fund’s maximum exposure under these arrangements is unknown, as this would involve any future potential claims that may be made against the Institutional TEI W Fund. However, based on experience, the General Partner expects that risk of loss to be remote.

On March 31, 2014 the Master Fund transferred in-kind a portfolio of Investment Funds to The Endowment PMF Master Fund, L.P. (the “PMF Master Fund”), in exchange for limited partnership interests (the “Interests”) of the PMF Master Fund totaling $1,723,272,229. The transfer was accounted for as a tax-free transaction resulting in Investment Funds transferring to the PMF Master Fund with a total value of $1,490,836,309, consisting of total cost and accumulated appreciation of $1,317,376,887 and $173,459,422, respectively, and cash and other assets of $232,435,920. Partners in the Institutional TEI W Fund elected to transfer $11,520,604 of Interests from the Institutional TEI W Fund to PMF TEI Fund L.P., a feeder fund of the PMF Master Fund, in exchange for Interests in such feeder fund.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES

(a) BASIS OF ACCOUNTING

The accounting and reporting policies of the Institutional TEI W Fund conform with U.S. generally accepted accounting principles (“U.S. GAAP”). The accompanying financial statements reflect the financial position of the Institutional TEI W Fund and the results of its operations. The Institutional TEI W Fund is an investment company and follows the investment company accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, “Financial Services— Investment Companies”.

(b) CASH EQUIVALENTS

The Institutional TEI W Fund considers all unpledged temporary cash investments with a maturity date at the time of purchase of three months or less to be cash equivalents.

(c) INVESTMENT SECURITIES TRANSACTIONS

The Institutional TEI W Fund records monthly, its pro-rata share of income, expenses, changes in unrealized appreciation and depreciation, and realized gains and losses derived from the Offshore Institutional W Fund.

The Institutional TEI W Fund records investment transactions on a trade-date basis.

Investments that are held by the Institutional TEI W Fund are marked to fair value at the date of the financial statements, and the corresponding change in unrealized appreciation/depreciation is included in the Statement of Operations.

December 31, 2015

(d) INVESTMENT VALUATION

The valuation of the Institutional TEI W Fund’s investments is determined as of the close of business at the end of each reporting period, generally monthly. The valuation of the Institutional TEI W Fund’s investments is calculated by UMB Fund Services, Inc., the Institutional TEI W Fund’s independent administrator (the “Administrator”).

The Board has formed a valuation committee (the “Board Valuation Committee”) that is responsible for overseeing the Institutional TEI W Fund’s valuation policies, making recommendations to the Board on valuation-related matters, and overseeing implementation by the Adviser of such valuation policies.

The Board has authorized the Adviser to establish a valuation committee of the Adviser (the “Adviser Valuation Committee”). The Adviser Valuation Committee’s function, subject to the oversight of the Board Valuation Committee and the Board, is generally to review valuation methodologies, valuation determinations, and any information provided to the Adviser Valuation Committee by the Adviser or the Administrator.

The Institutional TEI W Fund invests substantially all of its assets in the Offshore Institutional W Fund, which in turn invests substantially all of its assets in the Master Fund. Investments in the Master Fund are recorded at fair value based on the Institutional TEI W Fund’s proportional share of the Master Fund’s partners’ capital, through the Offshore Institutional W Fund. Valuation of the investments held by the Master Fund is discussed in the Master Fund’s notes to financial statements, included elsewhere in this report.

(e) INVESTMENT INCOME

For investments in securities, dividend income is recorded on the ex-dividend date, net of withholding taxes. Interest income is recorded as earned on the accrual basis and includes amortization of premiums or accretion of discounts.

(f) FUND EXPENSES

Unless otherwise voluntarily or contractually assumed by the Adviser or another party, the Institutional TEI W Fund bears all expenses incurred in its business, directly or indirectly through its investment in the Master Fund (through the Offshore Institutional W Fund), including but not limited to, the following: all costs and expenses related to investment transactions and positions for the Institutional TEI W Fund’s account; legal fees; accounting, auditing and tax preparation fees; recordkeeping and custodial fees; costs of computing the Institutional TEI W Fund’s net asset value; fees for data and software providers; research expenses; costs of insurance; registration expenses; offering costs; expenses of meetings of the partners; directors fees; all costs with respect to communications to partners; offshore withholding taxes; and other types of expenses as may be approved from time to time by the Board.

(g) INCOME TAXES

The Institutional TEI W Fund is organized and operates as a limited partnership and is not subject to income taxes as a separate entity. Such taxes are the responsibility of the individual partners. Accordingly, no provision for income taxes has been made in the Institutional TEI W Fund’s financial statements. Investments in foreign securities may result in foreign taxes being withheld by the issuer of such securities.

Notes to Financial Statements, continued

December 31, 2015

For the current open tax year and for all major jurisdictions, management of the Institutional TEI W Fund has evaluated the tax positions taken or expected to be taken in the course of preparing the Institutional TEI W Fund’s tax returns to determine whether the tax positions will “more-likely-than-not” be sustained by the Institutional TEI W Fund upon challenge by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold and that would result in a tax benefit or expense to the Institutional TEI W Fund would be recorded as a tax benefit or expense in the current period. For the year ended December 31, 2015, the Institutional TEI W Fund did not recognize any amounts for unrecognized tax benefit/expense. A reconciliation of unrecognized tax benefit/expense is not provided herein, as the beginning and ending amounts of unrecognized tax benefit/expense are zero, with no interim additions, reductions or settlements. Tax positions taken in tax years which remain open under the statute of limitations (generally three years for federal income tax purposes) are subject to examination by federal and state tax jurisdictions.

(h) USE OF ESTIMATES

The financial statements have been prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results may differ from those estimates and such differences may be significant.

(i) ORGANIZATIONAL EXPENSES

The Institutional TEI W Fund’s organizational expenses (the “Organizational Expenses”) were initially borne by the Adviser or an affiliate thereof and for capital account allocation purposes assumed to be reimbursed, over not more than a 60 month period of time, notwithstanding that such Organizational Expenses were expensed in accordance with U.S. GAAP for Institutional TEI W Fund financial reporting purposes upon commencement of operations.

(3) FAIR VALUE MEASUREMENTS

The Institutional TEI W Fund records its investment in the Offshore Institutional W Fund, which in turn invests substantially all of its assets in the Master Fund, at fair value. Investments of the Master Fund are recorded at fair value as more fully discussed in the Master Fund’s notes to financial statements, included elsewhere in this report.

(4) PARTNERS’ CAPITAL ACCOUNTS

(a) ISSUANCE OF INTERESTS

Upon receipt from an eligible investor of an initial or additional application for interests (the “Interests”), which will generally be accepted as of the first day of each month, the Institutional TEI W Fund will issue new Interests. The Interests have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state. The Institutional TEI W Fund issues Interests only in private placement transactions in accordance with Regulation D or other applicable exemptions under the Securities Act. No public market exists for the Interests, and none is expected to develop. The Institutional TEI W Fund is not required, and does not intend, to hold annual meetings of its partners. The Interests are subject to substantial restrictions on transferability and resale and may not be transferred or resold except as permitted under the Institutional TEI W Fund’s limited partnership agreement. The Institutional TEI W Fund reserves the right to reject any applications for subscription of Interests.

Notes to Financial Statements, continued

December 31, 2015

(b) ALLOCATION OF PROFITS AND LOSSES

For each fiscal period, generally monthly, net profits or net losses of the Institutional TEI W Fund, including allocations from the Master Fund (through the Offshore Institutional W Fund), are allocated among and credited to or debited against the capital accounts of all partners as of the last day of each fiscal period in accordance with the partners’ respective capital account ownership percentage for the fiscal period. Net profits or net losses are measured as the net change in the value of the partners’ capital of the Institutional TEI W Fund, including any change in unrealized appreciation or depreciation of investments and income, net of expenses, and realized gains or losses during a fiscal period. Net profits or net losses are allocated after giving effect for any initial or additional applications for Interests, which generally occur at the beginning of the month, or any repurchases of Interests.

(c) REPURCHASE OF INTERESTS

A partner will not be eligible to have the Institutional TEI W Fund repurchase all or any portion of an Interest at the partner’s discretion at any time. The Adviser, which also serves as the investment adviser of the Master Fund and Offshore Institutional W Fund, generally recommends to the Board that the Institutional TEI W Fund offer to repurchase such Interests each calendar quarter, pursuant to written tenders by partners.

The Board retains the sole discretion to accept or reject the recommendation of the Adviser and to determine the amount of Interests, if any, that will be purchased in any tender offer that it does approve. Since the Institutional TEI W Fund’s assets are invested in the Master Fund (through the Offshore Institutional W Fund), the ability of the Institutional TEI W Fund to have its Interests in the Master Fund be repurchased would be subject to the Master Fund’s and Offshore Institutional W Fund’s repurchase policies. The Master Fund’s and Offshore Institutional W Fund’s repurchase policies are substantially similar to the Institutional TEI W Fund’s repurchase policy as any tender offer by the Master Fund (through the Offshore Institutional W Fund) is subject to the sole discretion of the Board. In addition, the Institutional TEI W Fund may determine not to conduct a repurchase offer each time the Master Fund and Offshore Institutional W Fund conduct a repurchase offer. In the event Interests are repurchased, there will be a substantial period of time between the date as of which partners must tender their Interests for repurchase and the date they can expect to receive payment for their Interests from the Institutional TEI W Fund.

(5) INVESTMENTS IN PORTFOLIO SECURITIES

As of December 31, 2015, all of the investments made by the Institutional TEI W Fund were in the Master Fund (through the Offshore Institutional W Fund).

(6) FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business, the Investment Funds in which the Institutional TEI W Fund may invest either directly or through the Offshore Institutional W Fund and Master Fund may trade various derivative securities and other financial instruments, and enter into various investment activities with off-balance sheet risk both as an investor and as a principal. The Institutional TEI W Fund’s risk of loss in these Investment Funds is limited to the Institutional TEI W Fund’s pro rata share of the value of its investment in or commitment to such Investment Funds as held directly or through the Offshore Institutional W Fund and Master Fund. In addition, the Master Fund may invest directly in derivative securities or other financial instruments to gain greater or lesser exposure to a particular asset class.

(7) ADMINISTRATION AGREEMENT

In consideration for administrative, accounting, and recordkeeping services, the Master Fund pays the Administrator a monthly administration fee based on the month-end partners’ capital of the Master Fund. The Administrator also provides the Institutional TEI W Fund, the Offshore Institutional W Fund and the Master Fund with compliance, transfer agency, and other investor related services at an additional cost.

The fees for Institutional TEI W Fund administration are paid out of the Master Fund’s assets, which decreases the net profits or increases the net losses of the partners in the Institutional TEI W Fund.

(8) RELATED PARTY TRANSACTIONS

(a) INVESTMENT MANAGEMENT FEE

In consideration of the advisory and other services provided by the Adviser to the Master Fund and the Institutional TEI W Fund, the Master Fund pays the Adviser an investment management fee (the “Investment Management Fee”) equal to 1.00% on an annualized basis of the Master Fund’s partners’ capital calculated based on the Master Fund’s partners’ capital at the end of each month, payable quarterly in arrears. So long as the Institutional TEI W Fund invests all of its investable assets in the Offshore Institutional W Fund, which in turn invests all of its investable assets in the Master Fund, the Institutional TEI W Fund will not pay the Adviser directly any Investment Management Fee; however, should the Institutional TEI W Fund not have all of its investments in the Offshore Institutional W Fund, it may be charged the 1.00% Investment Management Fee directly. The Institutional TEI W Fund’s partners bear an indirect portion of the Investment Management Fee paid by the Master Fund. The Investment Management Fee decreases the net profits or increases the net losses of the Master Fund and indirectly the Institutional TEI W Fund as the fees reduce the capital accounts of the Master Fund’s partners.

(b) PLACEMENT AGENTS

The Institutional TEI W Fund may engage one or more placement agents (each, a “Placement Agent”) to solicit investments in the Institutional TEI W Fund. Salient Capital, L.P., an affiliate of the Adviser, is a broker- dealer who has been engaged by the Institutional TEI W Fund to serve as a Placement Agent. A Placement Agent may engage one or more sub-placement agents. The Adviser or its affiliates may pay a fee out of their own resources to Placement Agents and sub-placement agents.

An investor’s return (and operating ratios) may vary from those reflected based on the timing of capital transactions.

1 The Institutional TEI W Fund commenced operations on January 1, 2011.

2 Ratios are calculated by dividing the indicated amount by average partners’ capital measured at the end of each month during the period. Ratios include allocations of net investment loss and expenses from the Offshore Institutional W Fund and Master Fund. These ratios have been annualized for periods less than twelve months.

3 Ratio includes expenses reimbursed by the Adviser. Had the Organizational Expenses not been included as an expense at Inception and were instead amortized over 60 months as they are being handled for capital allocation purposes, the ratio of net expenses to average partners’ capital would have been 1.75% for the year ended December 31, 2011. (see Note 2)

4 The Institutional TEI W Fund is invested exclusively in the Offshore Institutional W Fund, which in turn is invested solely in the Master Fund, therefore this ratio reflects the portfolio turnover of the Master Fund, which is for the period indicated.

5 Calculated as geometrically linked monthly returns for each month in the period. Total returns are not annualized for periods less than twelve months.

6 Calculated including benefit of early repurchase fees in each applicable year. Had these early repurchase fees not been included as income for the purposes of the total return calculation, the total return for 2012 would have been 1.80%.

7 The reported total return amount for the year ended December 31, 2011, is negatively impacted by the write off of the Institutional TEI W and the Offshore Institutional W Funds’ Organizational Expenses, which occurred at Inception of the Institutional TEI W and Offshore Institutional W Funds’ operations in accordance with U.S. GAAP. Had these costs not been included as an expense at Inception for the purposes of the total return calculation and were instead amortized over 60 months as they are being handled for capital allocation purposes, the total return would have been (3.99)% for the year ended December 31, 2011.

(10) SUBSEQUENT EVENTS

Based on the partners’ capital of the Institutional TEI W Fund, the Adviser recommended to the Board that a tender offer in an amount of up to $74,000 be made for the quarter ending March 31, 2016 to those partners who elect to tender their Interests prior to the expiration of the tender offer period. The Board approved such

Notes to Financial Statements, continued

December 31, 2015

recommendation and partners in the Institutional TEI W Fund were notified of a tender offer with a March 2, 2016 expiration date (“Expiration Date”). In response to the number of partners electing to tender their Interests as of the Expiration Date, which amounted to approximately $63 million, the Adviser, in its discretion, will pro-rate the amount elected to be tendered in accordance with the Institutional TEI W Fund’s repurchase procedures. The final amount that is accepted by the Master Fund, and subsequently the Institutional TEI W Fund, will appear in the next report to partners.

Management of the Institutional TEI W Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. Based on this evaluation, no adjustments were required to the financial statements as of December 31, 2015.

The Endowment Master Fund, L.P.:

We have audited the accompanying statement of assets, liabilities and partners’ capital of The Endowment Master Fund, L.P. (the “Master Fund”), including the schedule of investments, as of December 31, 2015, and the related statements of operations and cash flows for the year then ended, the statements of changes in partners’ capital for each of the years in the two-year period then ended and the financial highlights for each of the years in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Master Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2015, by correspondence with custodians and investees or other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Master Fund as of December 31, 2015, the results of its operations and its cash flows for the year then ended, the changes in its partners’ capital for each of the years in the two-year period then ended and the financial highlights for each of the years in the five-year period then ended in conformity with U.S. generally accepted accounting principles.

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

Notes to Financial Statements

December 31, 2015

(1) ORGANIZATION

The Endowment Master Fund, L.P. (the “Master Fund”) a Delaware limited partnership, commenced operations on April 1, 2003. The Master Fund operated as an unregistered investment vehicle until March 10, 2004, at which time it registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Master Fund is the master fund in a master-feeder structure in which there are currently eight feeder funds.

The Master Fund’s investment objective is to preserve capital and to generate consistent long-term appreciation and returns across a market cycle (which is estimated to be five to seven years). The Master Fund is primarily a “fund of funds” which pursues its investment objective by investing its assets in a variety of investment vehicles including, but not limited to, limited partnerships, limited liability companies, hedge funds, offshore corporations and other foreign investment vehicles (collectively, the “Investment Funds”), registered investment companies (including exchange-traded funds) and direct investments in marketable securities and derivative instruments. The Investment Funds are managed by a carefully selected group of investment managers, identified by the Adviser, as hereinafter defined. The various styles and strategies employed by the Investment Funds and supplemented by the Master Fund’s direct investments, serve to achieve a portfolio that is broadly allocated.

The Endowment Fund GP, L.P., a Delaware limited partnership, serves as the general partner of the Master Fund (the “General Partner”). To the fullest extent permitted by applicable law, the General Partner has irrevocably delegated to a board of directors (the “Board” and each member a “Director”) its rights and powers to monitor and oversee the business affairs of the Master Fund, including the complete and exclusive authority to oversee and establish policies regarding the management, conduct, and operation of the Master Fund’s business. A majority of the members of the Board are independent of the General Partner and its management. To the extent permitted by applicable law, the Board may delegate any of its rights, powers and authority to, among others, the officers of the Master Fund, the Adviser, as hereinafter defined, or any committee of the Board.

The Board is authorized to engage an investment adviser, and pursuant to an investment management agreement, (the “Investment Management Agreement”), it has selected Endowment Advisers, L.P. (the “Adviser”), to manage the Master Fund’s portfolio and operations. The Adviser is a Delaware limited partnership that is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Management Agreement, the Adviser is responsible for the establishment of an investment committee (the “Investment Committee”), which is responsible for developing, implementing, and supervising the Master Fund’s investment program subject to the ultimate supervision of the Board.

Under the Master Fund’s organizational documents, the Master Fund’s Directors and officers are indemnified against certain liabilities arising out of the performance of their duties to the Master Fund. In the normal course of business, the Master Fund enters into contracts with service providers, which also provide for indemnifications by the Master Fund. The Master Fund’s maximum exposure under these arrangements is unknown, as this would involve any future potential claims that may be made against the Master Fund. However, based on experience, the General Partner expects that risk of loss to be remote.

On March 31, 2014 the Master Fund transferred in-kind a portfolio of Investment Funds to The Endowment PMF Master Fund, L.P. (the “PMF Master Fund”), in exchange for limited partnership interests (the “Interests”) of the PMF Master Fund totaling $1,723,272,229. The transfer was accounted for as a tax-free transaction

THE ENDOWMENT MASTER FUND, L.P.

resulting in Investment Funds transferring to the PMF Master Fund with a total fair value of $1,490,836,309, consisting of total cost and accumulated appreciation of $1,317,376,887 and $173,459,422, respectively, and cash and other assets of $232,435,920.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES

(a) BASIS OF ACCOUNTING

The accounting and reporting policies of the Master Fund conform with U.S. generally accepted accounting principles (“U.S. GAAP”). The accompanying financial statements reflect the financial position of the Master Fund and the results of its operations. The Master Fund is an investment company that follows the investment company accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, “Financial Services-Investment Companies”.

(b) CASH EQUIVALENTS

The Master Fund considers all unpledged temporary cash investments with a maturity date at the time of purchase of three months or less to be cash equivalents.

(c) INVESTMENT SECURITIES TRANSACTIONS

The Master Fund records investment transactions on a trade-date basis.

Investments that are held by the Master Fund, including those that have been sold short, are marked to fair value at the date of the financial statements, and the corresponding change in unrealized appreciation/ depreciation is included in the Statement of Operations.

Dividend income is recorded on the ex-dividend date. Other investment fund distributions are recorded based on the detail provided with the distribution notice, as applicable. Realized gains or losses on the disposition of investments are accounted for based on the first in first out method.

(d) INVESTMENT VALUATION

The valuation of the Master Fund’s investments is determined as of the close of business at the end of each reporting period, generally monthly. The valuation of the Master Fund’s investments is calculated by UMB Fund Services, Inc., the Master Fund’s independent administrator (the “Administrator”).

The Board has formed a valuation committee (the “Board Valuation Committee”) that is responsible for overseeing the Master Fund’s valuation policies, making recommendations to the Board on valuation-related matters, and overseeing implementation by the Adviser of such valuation policies.

The Board has authorized the Adviser to establish a valuation committee of the Adviser (the “Adviser Valuation Committee”). The Adviser Valuation Committee’s function, subject to the oversight of the Board Valuation Committee and the Board, is generally to review valuation methodologies, valuation determinations, and any information provided to the Adviser Valuation Committee by the Adviser or the Administrator.

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

Notes to Financial Statements, continued

December 31, 2015

The Master Fund is not able to obtain complete underlying investment holding details on each of the Investment Funds in order to determine if the Master Fund’s proportional, aggregated, indirect share of any investments held by the Investment Funds exceeds 5% of partners’ capital of the Master Fund as of December 31, 2015.

Investments held by the Master Fund are valued as follows:

• INVESTMENT FUNDS—Investments in Investment Funds are carried at fair value, using the net asset value (the “NAV”) as a practical expedient, as provided to the Administrator by the investment managers of such Investment Funds or the administrators of such Investment Funds. These Investment Funds value their underlying investments in accordance with policies established by such Investment Funds. Prior to investing in any Investment Fund, the Adviser Valuation Committee, as part of the due diligence process, conducts a review of the valuation methodologies employed by the Investment Fund to determine whether such methods are appropriate for the asset types. All of the Master Fund’s valuations utilize financial information supplied by each Investment Fund and are net of management and estimated performance incentive fees or allocations payable to the Investment Funds’ managers pursuant to the Investment Funds’ agreements. Generally, Investment Funds in which the Master Fund invests will use market value when available, and otherwise will use principles of fair value applied in good faith. The Adviser Valuation Committee will consider whether it is appropriate, in light of the relevant circumstances, to value shares at NAV as reported by an Investment Fund for valuation purposes, or whether to adjust such reported value to reflect an adjusted fair value. Because of the inherent uncertainty of valuation, fair value may differ significantly from the value that would have been used had readily available markets for the investments in Investment Funds existed. The Master Fund’s investments in Investment Funds are subject to the terms and conditions of the respective operating agreements and offering memoranda of such Investment Funds.

• SECURITIES LISTED ON A SECURITIES EXCHANGE OR OVER-THE-COUNTER EXCHANGES—In general, the Master Fund values these securities at their last sales price on the exchange or over-the-counter market on the valuation date. If the security is listed on more than one exchange, the Master Fund uses the price from the exchange that it considers to be the principal exchange on which the security is traded. If there have been no sales for that day on the exchange where the security is principally traded, then the price of the security will be valued at the mean between the closing bid and ask prices on the valuation date. In these situations, valuations are typically categorized as Level 1 in the fair value hierarchy. Securities traded on a foreign securities exchange will generally be valued at their closing prices on the exchange where such securities are primarily traded, and translated into U.S. dollars at the current exchange rate. If an event occurred between the close of the foreign exchange and the valuation date of the Master Fund’s NAV that would materially affect the value of the security and the NAV of the Master Fund, the value of such security and the NAV of the Master Fund will be adjusted to reflect the change in the estimated value of the security. Such fair valued securities are typically categorized as Level 2 in the fair value hierarchy, based upon the inputs used to value the securities.

• DERIVATIVES—Exchange traded futures contracts are valued using quoted final settlement prices from the national exchange on which they are principally traded and are typically categorized as Level 1 in the fair value hierarchy. If no such sales price is reported by such exchange on the valuation date, the Adviser Valuation Committee will determine the fair value in good faith using information that is available at such time. Such fair valued investments are typically categorized as Level 2 or Level 3 in the fair value hierarchy, based upon the inputs used to value the investments.

Options that are listed on a securities exchange are generally valued on the valuation date at the closing mid of posted market on the exchange on which they are listed and are typically categorized as Level 1 in fair value hierarchy. If on the valuation date the primary exchange is closed, the prior day price will be used. If no such price is reported, the fair value of such options will be determined in good faith using industry standard pricing models utilizing publicly available input information on the valuation date.

Such fair valued investments are typically categorized as Level 2 or Level 3 in the fair value hierarchy, based upon the inputs used to value the investments.

Options traded on an over-the-counter market are generally valued using the midpoint of the closing bid and ask price provided by an independent pricing service. If a quotation is not available from the independent pricing service, the price is obtained from a broker (typically the counterparty to the option) on the valuation date. If no such price is available on the valuation date, the Adviser Valuation Committee in conjunction with the Administrator will determine the fair value of such options in good faith using information that is available at such time. Such fair valued options are typically categorized as Level 2 or Level 3 in the fair value hierarchy, based upon the inputs used to value the investments.

Non exchange-traded derivatives, such as swap agreements, are valued based on procedures approved by the Board and are typically categorized as Level 2 in the fair value hierarchy. Credit default swaps and total return swaps are generally fair valued using evaluated quotes provided by an independent pricing service. If a quotation is not available from the independent pricing service, the price is obtained from a broker (typically the counterparty to the swap agreement) on the valuation date.

Forward foreign currency exchange contracts are valued at prices supplied by an approved Pricing Vendor. The Pricing Vendor will consider spot and forward market prices and various other relevant factors in determining the fair values. Such valuations are provided by a pricing service approved by the Board, and are typically categorized as Level 2 in the fair value hierarchy.

• OTHER—Investments in open-end registered investment companies (“RICs”) that do not trade on an exchange are valued at the end of day NAV per share and are categorized as Level 1 in the fair value hierarchy. Where no value is readily available from a RIC or other security, or where a value supplied by a RIC is deemed not to be indicative of the RIC’s value, the Adviser Valuation Committee and/or the Board Valuation Committee, in consultation with the Administrator or the Adviser, will determine, in good faith, the fair value of the RIC or other security. Such fair valued investments are typically categorized as Level 1 or Level 2 in the fair value hierarchy, based upon the inputs used to value the investments.

Fixed-income securities are valued according to prices as furnished by an independent pricing service or broker/dealer quotes and are typically categorized as Level 2 in the fair value hierarchy. Fixed-income securities maturing within a relatively short time frame may be valued at amortized cost, which approximates market value, and are typically categorized as Level 2 in the fair value hierarchy.

• SECURITIES NOT ACTIVELY TRADED—The value of securities, derivatives or synthetic securities that are not actively traded on an exchange shall be determined by obtaining quotes from brokers that normally deal in such securities or by an unaffiliated pricing service that may use actual trade data or procedures using market indices, matrices, yield curves, specific trading characteristics of certain

42

groups of securities, pricing models or a combination of these procedures pursuant to the valuation procedures approved by the Board. In each of these situations, valuations are typically categorized as Level 2 or Level 3 in the fair value hierarchy, based upon the inputs used to value the investments.

(e) FOREIGN CURRENCY

The accounting records of the Master Fund are maintained in U.S. dollars. Foreign currency amounts and investments denominated in a foreign currency, if any, are translated into U.S. dollar amounts at current exchange rates on the valuation date. Purchases and sales of investments denominated in foreign currencies are translated into U.S. dollar amounts at the exchange rate on the respective dates of such transactions. The Master Fund does not segregate the results of operations resulting from changes in foreign exchange rates on investments from fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments and foreign currency translations reported in the accompanying Statement of Operations and Statement of Changes in Partners’ Capital.

(f) DERIVATIVE INSTRUMENTS

All open derivative positions at period-end, if any, are presented in the Master Fund’s Schedules of Investments. The Investment Funds may have directly engaged in derivative transactions during the period. The following is a description of the derivative instruments the Master Fund utilizes as part of its investment strategy, including the primary underlying risk exposures related to each instrument type.

OPTIONS CONTRACTS—The Master Fund may invest in options contracts to speculate on the price movements of a financial instrument or for use as an economic hedge against certain positions held in the Master Fund’s portfolio. Options contracts purchased give the Master Fund the right, but not the obligation, to buy or sell the underlying instrument for a specified price upon exercise at any time during the option period. Options contracts written obligate the Master Fund to buy or sell the underlying instrument for a specified price upon exercise at any time during the option period. When the Master Fund writes an options contract, an amount equal to the premium received by the Master Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option contract written.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS—The Master Fund may enter into forward foreign currency exchange contracts in connection with its investment objective in order to gain more or less exposure to foreign currencies. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized gains or losses until the contract settlement date. The Master Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The Master Fund remains subject to credit risk with respect to the amount it expects to receive from counterparties. However, the Master Fund has sought to mitigate these risks by generally requiring the posting of collateral at prearranged exposure levels to cover its exposure to the counterparty.

FUTURES CONTRACTS—The Master Fund may invest in futures contracts as part of its hedging strategy to manage exposure to interest rate, equity and market price movements, and commodity prices. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date. The underlying asset is not physically delivered. Futures contracts are valued at their quoted daily

43

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

Notes to Financial Statements, continued

December 31, 2015

settlement prices. Upon entering into a futures contract, the Master Fund is required to segregate liquid assets in accordance with the initial margin requirements of the clearinghouse to secure the Master Fund’s performance. The clearinghouse also requires daily settlement of variation margin representing changes in the value of each contract. Fluctuations in the value of the contracts are recorded as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as net realized gain (loss) from futures contracts. The primary risks associated with the use of futures contracts are imperfect correlation between changes in fair values of the underlying assets and the prices of futures contracts, and the possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty.

SWAP AGREEMENTS—The Master Fund may invest in swap agreements, primarily credit default and total return swap agreements, as a part of its hedging strategy to manage credit and market risks.

A credit default swap agreement gives one party (the buyer) the right to recoup the economic value of a decline in the value of debt securities of the reference issuer if a credit event (a downgrade, bankruptcy or default) occurs. This value is obtained by delivering a debt security of the reference issuer to the party in return for a previously agreed upon payment from the other party (frequently, the par value of the debt security) or receipt of a net amount equal to the par value of the defaulted reference entity less its recovery value. The Master Fund is usually a net seller of credit default swap agreements.

The Master Fund as a seller of a credit default swap agreement would have the right to pay the par (or other agreed-upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer with respect to its debt obligations. In return, the Master Fund would receive from the counterparty a periodic stream of payments over the term of the agreement provided that no event of default or other credit event has occurred. If no default or other credit event occurs, the Master Fund would keep the stream of payments and would have no further obligations to the counterparty. As a seller, the Master Fund is subject to investment exposure on the notional amount of the swap agreement.

A total return swap agreement is a bilateral financial contract agreement where one party (the payer) agrees to pay the other (the receiver) the total return on a specified asset or index in exchange for a fixed or floating rate of return. A total return swap agreement allows the receiver or payer to derive the economic benefit of owning or having short exposure to an asset without owning or shorting the underlying asset directly. The receiver is entitled to the amount, if any, by which the notional amount of the total return swap agreement would have increased in value had it been invested in the particular instruments, plus an amount equal to any dividends or interest that would have been received on those instruments. In return, the payer is entitled to an amount equal to a fixed or floating rate of interest (e.g., a LIBOR based rate) on the notional amount of the swap agreement plus the amount, if any, by which the notional amount would have decreased in value had it been invested in such instruments, less any dividends or interest. The amounts to which each party is entitled are normally netted against each other, at periodic settlement dates, resulting in a single amount that is either due to or from each party.

In addition to being exposed to the credit risk of the underlying reference entity, swap agreements are subject to counterparty risk, market risk and interest rate risk. Swap agreements utilized by the Master Fund may not perform as expected. Risks may arise as a result of the failure of the counterparty to perform under the agreement. The loss incurred by the failure of a counterparty is generally limited to the market value and premium amounts recorded. The Master Fund considers the creditworthiness of each counterparty to a swap agreement in evaluating potential credit risk, and will not enter into any swap agreement unless the Adviser believes the counterparty to the transaction is creditworthy. Additionally, risks may arise from the unanticipated

December 31, 2015

movements in interest rates or in the value of the underlying reference assets. The Master Fund may use various techniques to minimize credit risk including early termination or reset and payment. Collateral, in the form of cash, is held in broker segregated accounts for swap agreements.

The following is a summary of the fair value of derivative instruments held directly by the Master Fund as of December 31, 2015, and where such derivatives are recorded:

	Assets		Liabilities
	Unrealized Gain on Swap Agreements		Unrealized Loss on Swap Agreements
Equity Risk Exposure:
Swap Agreements	$	12,306	$	—

The following is a summary of the effect of derivative instruments on the Statement of Operations for the year ended December 31, 2015:

	Net Realized Gain (Loss) from Derivative Instruments		Change in Unrealized Appreciation/ Depreciation  from Derivative Instruments
Equity Risk Exposure:
Swap Agreements	$	—	$	12,306

As described above, the Master Fund utilized derivative instruments to achieve its investment objective during the year ended December 31, 2015. The Master Fund may enter into International Swap and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) or similar agreements with its derivative contract counterparties whereby the Master Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. Under the ISDA Master Agreements in place at December 31, 2015, the Master Fund is subject to master netting agreements that allow for amounts owed between the Master Fund and the counterparty to be netted. The party that has the larger payable pays the excess of the larger amount over the smaller amount to the other party. The master netting agreements do not apply to amounts owed to or from different counterparties. At December 31, 2015, the Master Fund did not hold any derivatives with applicable master netting agreements which were presented on a net basis in the financial statements.

As of December 31, 2015, the Master Fund had one total return swap agreement with Societe Generale as the counterparty with an unrealized gain of $12,306 as presented in the Statement of Assets, Liabilities, and Partners’ Capital.

The following is a summary of the average monthly notional value of swap agreements in the Master Fund for the year ended December 31, 2015, as well as the notional value of swap agreements outstanding as of December 31, 2015:

	Average Monthly Notional Value		Notional Value Outstanding at December 31, 2015
Total Return swap Agreements	$	265,575	$	3,186,903

(g) CFTC REGULATION

On August 13, 2013, the Commodity Futures Trading Commission (“CFTC”) adopted rules to harmonize conflicting Securities and Exchange Commission (the “SEC”) and CFTC disclosure, reporting and recordkeeping requirements for RICs that do not meet an exemption from the definition of commodity pool. The harmonization rules provide that the CFTC will accept the SEC’s disclosure, reporting, and recordkeeping regime as substituted compliance for substantially all of the otherwise applicable CFTC regulations as long as such investment companies meet the applicable SEC requirements.

Previously, in November 2012, the CFTC issued relief for fund of fund operators, including advisers to RIC’s, that may otherwise be required to register with the CFTC as commodity pool operators but do not have access to information from the investment funds in which they are invested in order to determine whether such registration is required. This relief delayed the registration date for such operators until the later of June 30, 2013 or six months from the date the CFTC issues revised guidance on the application of certain thresholds with respect to investments in commodities held by funds of funds. In December 2012, the Master Fund filed as required with the CFTC in order to claim this no-action relief, which was effective upon receipt of the filing. Although the CFTC now has adopted harmonization rules applicable to investment companies that are deemed to be commodity pools, the CFTC has not yet issued guidance on how funds of funds are to determine whether they are deemed to be commodity pools. As of December 31, 2015, the Master Fund is not considered a commodity pool and continues to rely on the fund of fund no-action relief.

(h) INVESTMENT INCOME

For investments in securities, dividend income is recorded on the ex-dividend date, net of withholding taxes. Interest income is recorded as earned on the accrual basis and includes amortization of premiums or accretion of discounts.

(i) FUND EXPENSES

Unless otherwise voluntarily or contractually assumed by the Adviser or another party, the Master Fund bears all expenses incurred in its business including, but not limited to, the following: all costs and expenses related to investment transactions and positions for the Master Fund’s account; legal fees; accounting, auditing and tax preparation fees; recordkeeping and custodial fees; costs of computing the Master Fund’s net asset value; fees for data and software providers; research expenses; costs of insurance; registration expenses; offering costs; expenses of meetings of partners; directors fees; all costs with respect to communications to partners; transfer taxes; offshore withholding taxes and taxes withheld on non-U.S. dividends; interest and commitment fees on loans and debit balances; and other types of expenses as may be approved from time to time by the Board.

(j) INCOME TAXES

The Master Fund is organized and operates as a limited partnership and is not subject to income taxes as a separate entity. Such taxes are the responsibility of the individual partners. Accordingly, no provision for income taxes has been made in the Master Fund’s financial statements. Investments in foreign securities may result in foreign taxes being withheld by the issuer of such securities. For U.S. offshore withholding tax, the Master Fund may serve as withholding agent for its offshore feeder funds.

For the current open tax year and for all major jurisdictions, management of the Master Fund has evaluated the tax positions taken or expected to be taken in the course of preparing the Master Fund’s tax returns to

46

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

Notes to Financial Statements, continued

December 31, 2015

determine whether the tax positions will “more-likely-than-not” be sustained by the Master Fund upon challenge by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold and that would result in a tax benefit or expense to the Master Fund would be recorded as a tax benefit or expense in the current period.

For the year ended December 31, 2015, the Master Fund did not recognize any amounts for unrecognized tax benefit/expense. A reconciliation of unrecognized tax benefit/expense is not provided herein, as the beginning and ending amounts of unrecognized tax benefit/expense are zero, with no interim additions, reductions or settlements. Tax positions taken in tax years which remain open under the statute of limitations (generally three years for federal income tax purposes) are subject to examination by federal and state tax jurisdictions.

(k) USE OF ESTIMATES

The financial statements have been prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results may differ from those estimates and such differences may be significant.

(l) RESTRICTED SECURITIES

The Master Fund may invest a portion or all of the value of its assets in restricted securities and other investments that are illiquid. Restricted securities are securities that may not be sold to the public without an effective registration statement under the Securities Act of 1933 (the “Securities Act”) or, if they are unregistered, may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. These may include restricted securities that can be offered and sold only to “qualified institutional buyers” under Rule 144A of the Securities Act. There is no limit to the percentage of an Investment Fund’s net assets that may be invested in illiquid securities.

The restricted securities held at December 31, 2015 are identified below and are also presented in the Master Fund’s Schedule of Investments.

Security	% of Partners’ Capital			Acquisition Dates		Principal Amount		Cost		Fair Value
Nuclea Biotechnologies, Inc.*		0.2	%		1/5/15	$	700,000	$	700,000	$	798,000
Total Restricted Securities		0.2	%			$	700,000	$	700,000	$	798,000

* Security has been deemed illiquid by the Adviser based on procedures approved by the Board.

(3) FAIR VALUE MEASUREMENTS

The Master Fund defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions.

47

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

Notes to Financial Statements, continued

December 31, 2015

The inputs used to determine the fair value of the Master Fund’s investments are summarized in the three broad levels listed below:

• Level 1—unadjusted quoted prices in active markets for identical investments and registered investment companies where the value per share (unit) is determined and published and is the basis for current transactions for identical assets or liabilities at the valuation date

• Level 2—investments with other significant observable inputs

• Level 3—investments with significant unobservable inputs (which may include the Master Fund’s own assumptions in determining the fair value of investments)

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The Master Fund discloses transfers between levels based on valuations at the end of the reporting period. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

The Master Fund establishes valuation processes and procedures to ensure that the valuation techniques for investments categorized within Level 3 of the fair value hierarchy are fair, consistent, and appropriate. The Adviser is responsible for developing the Master Fund’s written valuation processes and procedures, conducting periodic reviews of the valuation policies, and evaluating the overall fairness and consistent application of the valuation policies. The Board Valuation Committee has authorized the Adviser to oversee the implementation of the Board approved valuation procedures by the Administrator. The Adviser Valuation Committee is comprised of various Master Fund personnel, which include members from the Master Fund’s portfolio management and operations groups. The Adviser Valuation Committee meets monthly or as needed, to determine the valuations of the Master Fund’s Level 3 investments. The valuations are supported by methodologies employed by the Investment Funds’ market data, industry accepted third party valuation models, or other methods the Adviser Valuation Committee deems to be appropriate, including the use of internal proprietary valuation models.

In April 2015, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), modifying Accounting Standards Codification (“ASC”) 820 Fair Value Measurement. The Master Fund has elected to early adopt and retrospectively apply ASU 2015-07. The impact of the early adoption of ASU 2015-07 has been reflected in the notes to the financial statements. Prior to this, investments valued using the practical expedient were categorized within the fair value hierarchy on the basis of whether the investment is redeemable with the investee at net asset value on the measurement date, never redeemable with the investee at net asset value, or redeemable with the investee at net asset value at a future date. The retroactive application of ASU 2015-07 results in the exclusion of any Investment Funds valued using NAV as practical expedient from the investment roll forward included in the December 31, 2014 audited financial statements. As a result of adopting ASU 2015-07, Investment Funds with a fair value of $326,700,148 are excluded from the fair value hierarchy as of December 31, 2015.

The following table is a summary of quantitative information about significant unobservable valuation inputs approved by the Adviser Valuation Committee for Level 3 fair value measurements for the investment held as of December 31, 2015:

	Fair Value as of December 31, 2015		Valuation Technique	Unobservable Input	Range of Unobservable Input
Investments

The following is a reconciliation of the Level 3 investment held at December 31, 2015 based on the inputs used to determine fair value:

	Balance as of December 31, 2014		Gross Purchases		Gross Sales		Net Realized Gain (Loss)		Change in Unrealized Appreciation/ Depreciation		Balance as of December 31, 2015

Total Investments	$	—	$	700,000	$	—	$	—	$	98,000	$	798,000

The change in unrealized appreciation/depreciation from Level 3 investments held at December 31, 2015 is $98,000.

The Master Fund is permitted to invest in alternative investments that may not have a readily determinable fair value. For an investment that does not have a readily determinable fair value, the Master Fund uses the NAV reported by the Investment Fund as a practical expedient, without further adjustment, unless it is probable that the investment will be sold at a value significantly different than the reported NAV. If the practical expedient NAV is not as of the reporting entity’s measurement date, then the NAV is adjusted to reflect any significant events that would materially affect the value of the investment and the NAV of the Master Fund as of the valuation date.

Certain Investment Funds in which the Master Fund invests have limitations on liquidity which may result in limitations on redemptions including, but not limited to, early redemption fees. Other than Investment Funds that are self-liquidating, such as Private Equity and some Energy, Natural Resources and Real Estate Funds, the Investment Funds in which the Master Fund invests have withdrawal rights ranging from monthly to annually, after a notice period, usually for a period of up to two years from the date of the initial investment or an additional investment. A listing of the investments held by the Master Fund and their attributes as of December 31, 2015, that qualify for this valuation approach is shown in the table below.

(4) PARTNERS’ CAPITAL ACCOUNTS

(a) ISSUANCE OF INTERESTS

Upon receipt from an eligible investor of an initial or additional application for interests (the “Interests”), which will generally be accepted as of the first day of each month, the Master Fund will issue new Interests. The Interests have not been registered under the Securities Act, or the securities laws of any state. The Master Fund issues Interests only in private placement transactions in accordance with Regulation D or other applicable exemptions under the Securities Act. No public market exists for the Interests, and none is expected to develop. The Master Fund is not required, and does not intend, to hold annual meetings of its partners. The Interests are subject to substantial restrictions on transferability and resale and may not be transferred or resold except as permitted under the Master Fund’s limited partnership agreement. The Master Fund reserves the right to reject any applications for subscription of Interests.

(b) ALLOCATION OF PROFITS AND LOSSES

For each fiscal period, generally monthly, net profits or net losses of the Master Fund are allocated among and credited to or debited against the capital accounts of all partners as of the last day of each fiscal period in accordance with the partners’ respective capital account ownership percentage for the fiscal period. Net profits or net losses are measured as the net change in the value of the partners’ capital of the Master Fund, including any change in unrealized appreciation or depreciation of investments and income, net of expenses, and realized gains or losses during a fiscal period. Net profits or net losses are allocated after giving effect for any initial or additional applications for Interests, which generally occur at the beginning of the month, or any repurchases of Interests.

(c) REPURCHASE OF INTERESTS

A partner will not be eligible to have the Master Fund repurchase all or any portion of an Interest at the partner’s discretion at any time. Periodically, the Adviser recommends to the Board that the Master Fund offer to repurchase Interests during the year, pursuant to written tenders by partners.

The Board retains the sole discretion to accept or reject the recommendation of the Adviser and to determine the amount of Interests, if any, that will be purchased in any tender offer that it does approve. In the event Interests are repurchased, there will be a substantial period of time between the date as of which partners must accept the Master Fund’s offer to repurchase their Interests and the date they can expect to receive payment for their Interests from the Master Fund.

(5) INVESTMENTS IN PORTFOLIO SECURITIES

(a) INVESTMENT ACTIVITY

As of December 31, 2015 the Master Fund held investments in Investment Funds and securities. The agreements related to investments in Investment Funds provide for compensation to the Investment Funds’ managers/general partners or advisers in the form of management fees of up to 3.0% annually of monthly average net assets. In addition, many Investment Funds also provide for performance incentive fees/allocations of up to 30% of an Investment Fund’s net profits, although it is possible that such ranges may be exceeded for certain investment managers. These management fees and incentive fees are in addition to the management fees charged by the Master Fund.

For the year ended December 31, 2015, the aggregate cost of purchases and proceeds from sales of investments (excluding short-term investments) were $71,064,526 and $42,883,946, respectively.

The cost of the Master Fund’s underlying investments for Federal income tax purposes is adjusted for items of taxable income allocated to the Master Fund from such investments. The allocated taxable income is generally reported to the Master Fund by its underlying investments on Schedules K-1, Forms 1099 or PFIC statements, or a combination thereof.

The underlying investments generally do not provide the Master Fund with tax reporting information until well after year end, and as a result, the Master Fund is unable to calculate the year end tax cost of its investments until such time. The Master Fund’s book cost as of December 31, 2015, was $310,678,584, resulting in accumulated net unrealized appreciation of $19,766,138 consisting of $67,181,541 in gross unrealized appreciation and $47,415,403 in gross unrealized depreciation.

During the year ended December 31, 2015, certain investments were received through a transfer-in-kind in connection with the redemption of certain investments. The fair value of these investments transferred-in-kind and related cost were as follows:

Investments Redeemed	Fair Value		Cost		Realized Gain (Loss) on Transfers In- Kind		Unrealized Gain (Loss) on Transfers In- Kind		Investments Received
Tiger Global Private Investment Partners V, L.P.	$	7,994,306	$	7,798,116	$	196,190	$	—		JD.com, Inc.

(b) AFFILIATED INVESTMENT FUNDS

At December 31, 2015, the Master Fund’s investments in certain Investment Funds were deemed to be investments in affiliated issuers under the 1940 Act, primarily because the Master Fund owns 5% or more of the Investment Funds’ total net assets. The activity resulting from investments in these Investment Funds, including interest and dividend income as well as realized gains and losses, is identified in the Statement of Operations as transactions with affiliated investments. A listing of these affiliated Investment Funds (including activity during the year ended December 31, 2015) is shown below:

(6) FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business, the Investment Funds in which the Master Fund invests may trade various derivative securities and other financial instruments, and may enter into various investment activities with off-balance sheet risk both as an investor and as a principal. The Master Fund’s risk of loss in these Investment Funds is limited to the value of its investment in such Investment Funds. In addition, by investing directly in derivative instruments, the Master Fund is subject to credit risk with respect to the net amount expected to be received from the other party. The Master Fund may be negatively impacted if the other party defaults or fails to perform its obligations under such agreement.

THE ENDOWMENT MASTER FUND, L.P.

(A Limited Partnership)

December 31, 2015

(7) ADMINISTRATION AGREEMENT

In consideration for administrative, accounting, and recordkeeping services, the Master Fund pays the Administrator a monthly administration fee based on the month-end partners’ capital of the Master Fund. The Master Fund is charged, on an annual basis, 6 basis points on partners’ capital of up to $2 billion, 5 basis points on partners’ capital between the amounts of $2 billion and $5 billion, 2 basis points on partners’ capital between the amounts of $5 billion and $15 billion, and 1.25 basis points for amounts over $15 billion. The administration fee is payable monthly in arrears. The Administrator also provides the Master Fund with, compliance, transfer agency, and other investor related services at an additional cost.

The administration fees are paid out of the Master Fund’s assets, which decreases the net profits or increases the net losses of the partners in the Master Fund. As of December 31, 2015, the Master Fund had $315,002,632 in partners’ capital. The total administration fee incurred for the year ended December 31, 2015, was $192,035.

(8) RELATED PARTY TRANSACTIONS

(a) INVESTMENT MANAGEMENT FEE

In consideration of the advisory and other services provided by the Adviser to the Master Fund pursuant to the Investment Management Agreement, the Master Fund pays the Adviser an investment management fee (the “Investment Management Fee”), equal to 1.00% on an annualized basis of the Master Fund’s partners’ capital calculated based on the Master Fund’s partners’ capital at the end of each month, payable quarterly in arrears. The Investment Management Fee decreases the net profits or increases the net losses of the Master Fund that are credited to or debited against the capital accounts of its partners. For the year ended December 31, 2015, $3,209,422 was incurred for Investment Management Fees.

(b) PLACEMENT AGENTS

The Master Fund may engage one or more placement agents (each, a “Placement Agent”) to solicit investments in the Master Fund. Salient Capital, L.P., an affiliate of the Adviser, is a broker-dealer who has been engaged by the Master Fund to serve as a Placement Agent. A Placement Agent may engage one or more sub-placement agents. The Adviser or its affiliates may pay a fee out of their own resources to Placement Agents and sub-placement agents. As of December 31, 2015, the two largest non-affiliated sub-placement agents service approximately 47.42% of the feeder funds assets which are invested in the Master Fund. To the extent that substantial numbers of investors have a relationship with a particular sub-placement agent, such sub-placement agent may have the ability to influence investor behavior, which may affect the Master Fund.

(9) FUND BORROWING

As a fundamental policy, the Master Fund may borrow up to, but not more than, 25% of the partners’ capital of the Master Fund (at the time such borrowings were made and after taking into account the investment and/or deployment of such proceeds) for the purpose of making investments, funding redemptions and for other working capital and general Master Fund purposes. For purposes of the Master Fund’s investment restrictions and certain investment limitations under the 1940 Act, including for example, the Master Fund’s leverage limitations, the Master Fund will not “look through” Investment Funds in which the Master Fund invests. Investment Funds may also use leverage, whether through borrowings, futures, or other derivative products and are not subject to the Master Fund’s investment restrictions. However, such borrowings by Investment Funds are without recourse to the Master Fund and the Master Fund’s risk of loss is limited to its investment in such Investment Funds, other

than for some Investment Funds in which the Master Fund has made a capital commitment, for which the risk of loss is limited to the Master Fund’s total capital commitment. For some Investment Funds in which the Master Fund has made a capital commitment that will be funded over a period of time, such as private equity, private energy and real estate funds, the Master Fund, in certain instances, may commit to fund more than its initial capital commitment. The rights of any lenders to the Master Fund to receive payments of interest or repayments of principal will be senior to those of the partners, and the terms of any borrowings may contain provisions that limit certain activities of the Master Fund.

The Master Fund entered into a line of credit agreement (the “Credit Agreement”) with Credit Suisse AG on October 29, 2014. The terms of the Credit Agreement provide a $60,000,000 secured revolving credit facility.

Borrowings under the Credit Agreement are secured by the Master Fund’s investments. The Credit Agreement provides for a commitment fee of 1.50% per annum on unused capacity above a certain threshold plus interest accruing on any borrowed amounts at the three month London Interbank Offered Rate (LIBOR) plus 2.24% per annum as defined in the Credit Agreement. The average principal balance and weighted average interest rate for the year ended December 31, 2015, was approximately $36,602,740 and 2.55% respectively. At December 31, 2015, the principal balance outstanding was $35,989,694 at an interest rate of 2.65%. The Credit Agreement expires on October 29, 2018.

An investor’s return (and operating ratios) may vary from those reflected based on the timing of capital transactions.

1 Ratios are calculated by dividing the indicated amount by average partners’ capital measured at the end of each month during the year.

2 Expense ratios do not include expenses of acquired funds that are paid indirectly by the Master Fund as a result of its ownership in the underlying funds. Expenses include U.S. offshore withholding tax, which is only allocable to investors investing through the offshore feeder funds.

3 Calculated as geometrically linked monthly returns for each month in the period.

(11) SUBSEQUENT EVENTS

Based on the partners’ capital of the Master Fund, the Adviser recommended to the Board that a tender offer in an amount of up to $6,243,000 be made for the quarter ending March 31, 2016 to those partners who elect to

57

tender their Interests prior to the expiration of the tender offer period. The Board approved such recommendation and partners in the Master Fund were notified of a tender offer with a March 2, 2016 expiration date (“Expiration Date”). In response to the number of partners electing to tender their Interests as of the Expiration Date, which amounted to approximately $63 million, the Adviser, in its discretion, will pro-rate the amount elected to be tendered in accordance with the Master Fund’s repurchase procedures. The final amount that is accepted by the Master Fund will appear in the next report to partners.

Management of the Master Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. Based on this evaluation, no adjustments were required to the financial statements as of December 31, 2015.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

The Adviser’s Investment Committee Members

As of the date of the filing, the Investment Committee is responsible for the day-to-day management of the Fund’s portfolio. The Endowment Master Fund, L.P. (the “Master Fund”), The Endowment Institutional Fund, L.P. (the “Institutional Fund”), The Endowment Registered Fund, L.P. (the “Registered Fund”), The Endowment TEI Fund, L.P. (the “TEI Fund”) and The Endowment Institutional TEI Fund W, L.P. (the “Institutional TEI W Fund”) are registered investment companies (collectively, the “Fund Complex” and each individually the “Fund”). The members of the Investment Committee (each an “Investment Committee Member”) are: Messrs. Lee G. Partridge, William B. Hunt and William R. Guinn.

Mr. Partridge has served as an Investment Committee Member since January 15, 2013, and has served as Chief Investment Officer of Salient Partners, L.P. (“Salient”), which owns Salient Trust Co., LTA, a trust company chartered under the laws of the State of Texas, since January 15, 2013. Mr. Hunt has served as an Investment Committee Member since 2014 and as Chief Risk Officer of Salient since 2014. He previously held positions as a Senior Analyst and Portfolio Manager of Iridian Asset Management (from 1996-2011) and Professor at Southern Methodist University (from 1991-2000). Mr. Guinn has served as an Investment Committee Member since 2014 and Director of Salient since 2013. Previously, he held the position of Director of Strategic Partnerships and Opportunistic Investments at the Teacher Retirement System of Texas (2009-2013). Each member of the Investment Committee reviews asset allocation recommendations made by the Adviser’s representatives, manager due diligence and recommendations and, by a majority vote of the Investment Committee, determines asset allocation and manager selection.

The Adviser and certain other entities controlled by the Principals manage investment programs which are similar to that of the Fund, and the Adviser and/or the Principals may in the future serve as an investment adviser or otherwise manage or direct the investment activities of other registered and/or private investment vehicles with investment programs similar to the Funds.

Other Accounts Managed by the Investment Adviser

Certain Investment Committee Members, who are primarily responsible for the day-to-day management of the Fund, also manage other registered investment companies, other pooled investment vehicles and other accounts, as indicated below. The following tables identify, as of December 31, 2015: (i) the number of registered investment companies, other pooled investment vehicles and other accounts managed by the Investment Committee Member and the total assets of such companies, vehicles and accounts; and (ii) the number and total assets of such companies, vehicles and accounts with respect to which the advisory fee is based on performance.

Name	Number of Other Accounts		Total Assets of Other Accounts		Number of Other Accounts Subject to a Performance Fee		Total Assets of Other Accounts Subject to a Performance Fee
Lee Partridge
Registered investment companies (1)		10	$	2.28 billion		0	$	—
Other pooled investment companies (1)		15	$	1.07 billion		3	$	287.52 million
Other accounts		371	$	53.75 million		3	$	53.75 million
William B. Hunt
Registered investment companies (1)		10	$	2.28 billion		0	$	—
Other pooled investment companies (1)		15	$	1.07 billion		3	$	287.52 million
Other accounts		371	$	53.75 million		3	$	53.75 million
William R. Guinn
Registered investment companies (1)		10	$	2.28 billion		0	$	—
Other pooled investment companies (1)		15	$	1.07 billion		3	$	287.52 million
Other accounts		371	$	53.75 million		3	$	53.75 million

(1) For registered investment companies and pooled investment vehicles managed, the number of vehicles reported for master-feeder structures includes both the master fund and feeder funds while the corresponding total assets reported reflect the assets of the master fund only.

Conflicts of Interest of the Adviser

From time to time, potential conflicts of interest may arise between an Investment Committee Member’s management of the investments of the Fund, on the one hand, and the management of other registered investment companies, pooled investment vehicles and other accounts (collectively, “other accounts”), on the other. The other accounts might have similar investment objectives or strategies as the Fund, track the same index the Fund tracks or otherwise hold, purchase, or sell securities that are eligible to be held, purchased or sold by the Fund. The other accounts might also have different investment objectives or strategies than the Fund.

Knowledge and Timing of Fund Trades. A potential conflict of interest may arise as a result of the Investment Committee Member’s day-to-day management of a Fund. Because of their positions with the Fund, the Investment Committee Members know the size, timing and possible market impact of the Fund’s trades. It is theoretically possible that the Investment Committee Members could use this information to the advantage of other accounts they manage and to the possible detriment of the Fund.

Investment Opportunities. A potential conflict of interest may arise as a result of the Investment Committee Member’s management of a number of accounts with varying investment guidelines. Often, an investment opportunity may be suitable for both the Fund and other accounts managed by the Investment Committee Member, but may not be available in sufficient quantities for both the Fund and the other accounts to participate fully. Similarly, there may be limited opportunity to sell an investment held by the Fund and other accounts. The Adviser has adopted policies and procedures reasonably designed to allocate investment opportunities on a fair and equitable basis over time.

Performance Fees. An Investment Committee Member may advise certain accounts with respect to which the advisory fee is based entirely or partially on performance. Performance fee arrangements may create a conflict of interest for the Investment Committee Member in that the Member may have an incentive to allocate the investment opportunities that he or she believes might be the most profitable to such other accounts instead of allocating them to the Fund.

Compensation to Investment Committee Members

Messrs. Partridge, Hunt and Guinn, as partners of Salient, indirectly own equity interests in the Adviser as well as in the general partner of another fund who is compensated directly on performance (based on an incentive allocation) and the size of the fund’s asset base. In addition, Messrs. Hunt and Guinn receive compensation based on objective and subjective performance assessments of their work, which may take into account the size of the Master Fund and the other funds within the Fund Complex and the management and servicing fees charged thereon, as well as other funds managed by Salient affiliates for which they have significant involvement. Mr. Partridge is the Chief Investment Officer of Salient and related affiliates and subsidiaries (collectively, the “Salient Group”), which pays him a base salary and bonus based on the performance of the Salient Group. These individuals are responsible for the investment processes and management of the Salient Group. Mr. Partridge believes that to the extent that they are successful in their investment endeavors, the greater the number of assets over time and the more significant their compensation and equity value will be from the Salient Group.
