Semi-Annual Report

September 30, 2016

Dear Fellow Shareholders,

The City National Rochdale High Yield Alternative Strategies Fund LLC (“Taxable Fund”) and City National Rochdale High Yield Alternative Strategies Fund TEI LLC (“TEI Fund”), (collectively “RHYAS”) seek to diversify clients’ traditional stock and bond only portfolios through inclusion of less traditional strategies focusing on the fixed income markets. For the six-month period ending September 30, 2016, the Taxable Fund returned +8.85%and the TEI Fund returned

+8.82% net of fees and expenses. The benchmark of this strategy comprises a 50% weight in the Barclays U.S. Corporate High Yield and a 50% weight in the Credit Suisse Leveraged Loan Index. The strategy benchmark returned

+8.69% over the previous six months. Year to date ended September 30, 2016, the Taxable Fund returned +8.35% and the TEI Fund returned +8.28% net of fees and expenses, with the benchmark returning +11.24% over the same period.  Our strategy is geared more towards the performance of the Loan index, which is up +7.46% over the same time period.

The asset classes the fund has exposure to were challenged in 2015, and began the year down a bit.  Since February we have seen a nice rebound in the markets with a lower expectation on defaults in the loan markets.  Spreads have tightened in 2016, investors have returned to the leveraged loan space, and the impact of lower energy prices did not play as big a part as was first expected.  Our strategy is focusing a bit more on our loan exposure, which performed very well for us this year.

Our biggest drawback in that space was not having an even greater exposure to the CLO space (Collateralized Loan Obligations).  While performance has been strong, we feel there is reason to keep in the portfolio.  Most notably, the investments are typically interest rate risk neutral.  In this period of rate uncertainty, our preference is to take risk on the credit or spread side of the equation.

The investment objective of the Fund is to focus on unique investment opportunities in less liquid Fixed Income instruments, typically unavailable in a mutual fund structure. Specifically, the Fund’s targeted investments include Collateralized Loan Obligations, Residential Mortgage Backed Securities and Distressed Debt/Asset Backed Securities. As we orient the strategy to capture attractive opportunities in yield based asset classes, our focus is on a limited set of managers who target greater risk adjusted returns through unique opportunities. We believe the strategy can complement an existing portfolio in one of two ways: first, as a fixed income replacement providing higher return from yields than traditional fixed income with commensurately higher volatility, and second, as a supplement to a portion of an equity allocation with similar volatility expectations. The Fund can serve as a risk stabilizer (reducing overall equity exposure) or a return enhancer (reducing overall fixed income exposure), while providing greater asset class diversification in either instance.

Outlook

The U.S. economy remains on a positive track, with modest but steady growth continuing through year end. Underlying economic fundamentals remain strong and we continue to see sentiment oscillate between pessimism and optimism. The swings in sentiment are understandable, considering underlying U.S. trend growth has been frustratingly slow, while quarterly GDP has been particularly volatile. Yet, through all the ups and downs, the U.S. economy has proven to be relatively durable, especially in the face of ongoing global headwinds.

The Federal Reserve has (slightly) raised short term interest rates, and is expected to do so again in the near future (we view a 90% outcome of a December 2016 rate increase).  The consumer has been leading the growth in the economy.  With wages rising and the labor market continuing to add jobs at a good pace, we expect consumer expenditures to advance at a solid 2%+ rate in the fourth quarter, we feel the Fed is more comfortable with an increase.

When rates inevitably do rise, we view this portfolio to be well positioned to adapt. The portfolio consists of Fixed Income based asset classes that are less sensitive to rising rates and more dependent on the macroeconomic landscape. We do believe there will continue to be bouts of volatility in the High Yield market over the next 12 months, and we see the managers taking advantage of this potential volatility.  For those investors willing to take on the higher risk for higher return, we believe City National Rochdale High Yield Alternative Strategies Fund is an appropriate addition to client portfolios, relative to Core Fixed Income. Again, many of the managers in this strategy have structured the investment to benefit from a rising rate environment through re-investment opportunities, or themes based on valuation of distressed assets.

Sincerely,

Garrett R. D’Alessandro, CFA, CAIA, AIF®

High Yield / Credit. The credit strategy involves investing in the securities of companies that are non-investment grade, high yield and or distressed. Often, a corporate event results in the re-pricing of these securities, which may lead to profits. A non-investment grade bond generally has a Standard & Poor's rating of lower than BBB- or a Moody's rating lower than Baa3. In the event of a corporate event such as bankruptcy or default, bonds that rank higher in the capital structure of the issuers, such as first lien bank loan or a senior secured bond have priority over other bonds deemed junior in ranking in the capital structure. The distressed and high-yield sub-strategy involves investing in the securities (bank loans and bonds) of companies experiencing financial or operational difficulties or otherwise having below investment grade credit ratings. These securities may trade at substantial discounts to par value, because, in part, certain classes of investors who cannot hold non-investment grade, high yield or distressed bonds are forced to sell at discounted prices. Profits are made based on two kinds of mispricings: (1) fundamental or intrinsic value, and (2) relative value between comparable securities. Hedge Fund Managers may also take long/short positions throughout the capital structure of leveraged companies to implement a negative or positive credit view in the marketplace with the intention to offer better risk adjusted returns than being outright long or short the market.

Structured Credit. Structured credit strategy invests in stressed/distressed non-corporate fixed income asset classes in non-traditional markets such as residential real estate, commercial real estate and asset backed lending that have become distressed and/or undergoing structural changes, with anticipated improvement in the fundamental value of the underlying asset. Economic downturns and fundamental uncertainties can cause forced selling of securitized assets associated with such markets. In general, profits are made by identifying and investing in securities priced significantly below their intrinsic values where the strategy can maximize long-term capital appreciation from earning interest income and cash flows from current amortizing principal payments, cash flows from liquidations and from the fundamental appreciation of the underlying assets. Investing in structured credit requires deep fundamental analysis of the underlying assets and the behavior of the borrowers. Managers may invest in structured credit securities at deep discounts to fair value. Profits are realized as these securities converge to or above fair value with fundamental improvements in underlying borrowers, assets or improved technical behavior. Typically, structured credit managers will take positions in both agency and non-agency RMBS, CMBS, CLO, and other consumer and commercial loan ABS. At times, the strategy may also entail positions in other income generating assets such as life settlements and annuities, trade finance, legal settlements, whole loans, etc.

Liquidating Positions. Liquidating positions from former investment strategies remain in the Fund due to redemption restrictions placed on them by Hedge Fund Managers either at their sole discretion or for other factors. Such factors include the magnitude of redemptions requested, portfolio valuation issues or market conditions.

City National Rochdale High Yield Alternative Strategies Master Fund LLC

Notes to Financial Statements

September 30, 2016 (Unaudited)

1. Organization

City National Rochdale High Yield Alternative Strategies Master Fund LLC (the "Master Fund") is a closed-end, non-diversified management investment company that was organized as a limited liability company under the laws of the State of Delaware on September 11, 2006 and serves as a master fund in a master feeder structure. City National Rochdale High Yield Alternative Strategies Fund LLC and City National Rochdale High Yield Alternative Strategies Fund TEI LLC (the “Feeder Funds”) serve as the feeder funds in the master feeder structure. Interests in the Master Fund are issued solely in private placement transactions that do not involve any "public offering" within the meaning of Section 4(2) of the Securities Act of 1933, as amended (the "1933 Act"). Investments in the Master Fund may be made only by U.S. and foreign investment companies, common or commingled trust funds, organizations or trusts described in Sections 401(a) or 501(a) of the Internal Revenue Code of 1986, as amended, or similar organizations or entities that are "accredited investors" within the meaning of Regulation D under the 1933 Act. The Master Fund is a registered investment company under the Investment Company Act of 1940, as amended (the “1940 Act”).

City National Rochdale, LLC (the “Manager” or "Adviser"), is the investment adviser to the Master Fund. The Manager delegates sub-investment advisory responsibilities to PineBridge Investments LLC (the “Sub-Adviser”) with respect to the Master Fund.

The Master Fund seeks to achieve its objective by investing substantially all of its assets in the securities of privately placed investment vehicles, typically referred to as hedge funds (“Hedge Funds" or "Investment Funds”) that pursue a variety of high yield income generating strategies.

The Master Fund’s investment objective is to generate income from investments in higher yielding investments with lower credit quality and higher volatility than investment grade fixed income securities. “Lower credit quality” in this objective means investments rated below BBB, and “higher volatility” means the fluctuations in principal will be greater than the fluctuations in price associated with investment grade fixed income securities. Under normal circumstances, at least 80% of the Master Fund’s total assets will be invested either directly, or indirectly through Investment Funds, in a variety of high yield income generating investments.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Master Fund.

Basis of Presentation and Use of Estimates

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”). The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Investments Valuation

Investments are carried at fair value. The fair value of alternative investments has been estimated using the Net Asset Value (“NAV”) as reported by the management of the respective alternative investment fund. Financial Accounting Standards Board (FASB) guidance provides for the use of NAV as a “Practical Expedient” for estimating fair value of alternative investments. NAV reported by each alternative investment fund is used as a practical expedient to estimate the fair value of the Master Fund’s interest therein.

Investments in Investment Funds are stated and recorded at fair value as determined in good faith by the Fair Value Committee in accordance with US GAAP. The Master Fund uses the NAV as reported by the Hedge Fund Managers, as a practical expedient, to determine the fair value of all the investments in Investment Funds which (a) do not have a readily determinable fair value and (b) either have the attributes of an investment company or prepare their financial statements consistent with the measurement principles of an investment company. Such values generally represent the Master Fund's proportionate share of the net assets of the Investment Funds as reported by the Hedge Fund Managers. Accordingly, the value of the investments in Investment Funds are generally increased by additional contributions to the Investment Funds and the Master Fund's share of net earnings from the Investment Funds, and decreased by distributions from the Investment Funds and the Master Fund's share of net losses from the Investment Funds.

Notes to Financial Statements

2. Significant Accounting Policies (continued)

Investment Valuations (continued)

The Sub-Adviser reviews the details of the reported information obtained from the Hedge Fund Managers and considers: (i) the measurement date of the NAV provided, (ii) the basis of accounting and, (iii) in instances where the basis of accounting is other than fair value, fair valuation information provided by the Hedge Fund Managers. The Sub-Adviser may make adjustments to the NAV of various Investment Funds to obtain the best estimate of fair value, which is consistent with the measurement principles of an investment company. Any determinations made by the Sub-Adviser will be reviewed and approved by the Adviser’s Fair-Value Committee, which has been designated by the Board to make all necessary fair value determinations.

The Master Fund has not maintained any positions in derivative instruments or directly engaged in hedging activities.

Fair Value Measurements

The Master Fund follows fair valuation accounting standards which establish an authoritative definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the measurements of fair value and a discussion in changes in valuation techniques and related inputs during the period. These standards define 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. The fair value hierarchy is organized into three levels based upon the assumptions (referred to as “inputs”) used in pricing the asset or liability. These standards state that “observable inputs” reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from independent sources and “unobservable inputs” reflect an entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. These inputs are summarized in the three broad levels listed below:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Master Fund has the ability to access.

Level 2 - Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

2.         Significant Accounting Policies (continued)

Fair Value Measurements (continued)

Level 3 - Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available, representing the Master Fund’s own assumptions about the assumptions a market participant would use in valuing the asset or liability, and would be based on the best information available.

Investments measured using the NAV as a practical expedient are not classified within the fair value hierarchy.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in these securities. See Note 3 – Investments.

Investment Income Recognition

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis and dividends are recorded on the ex-dividend date. Realized and unrealized gains and losses are included in the determination of income.

Fund Expenses

The expenses of the Master Fund include, but are not limited to, the following: legal fees; accounting and auditing fees; custodial fees; management fees; an incentive fee; costs of computing the Master Fund's net asset value; costs of insurance; registration expenses; due diligence, including travel and related expenses; expenses of meetings of the Board and officers; all costs with respect to communications to Members; and other types of expenses as may be approved from time to time by the Board.

Income Taxes

The Master Fund’s tax year end is December 31. The Master Fund is treated as a partnership for Federal income tax purposes. Each Member is responsible for the tax liability or benefit relating to such Member’s distributive share of taxable income or loss. Accordingly, no provision for Federal income taxes is reflected in the accompanying financial statements.

The Master Fund has adopted authoritative guidance on uncertain tax positions. The Master Fund recognizes the effect of tax positions when they are more likely than not of being sustained. Management is not aware of any exposure to uncertain tax positions that could require accrual or which could affect its liquidity or future cash flows. As of September 30, 2016, the Master Fund’s tax years 2014 through 2016 remain open and subject to examination by relevant taxing authorities.

2. Significant Accounting Policies (continued)

Subsequent Events

The Master Fund has adopted financial reporting rules regarding subsequent events, which requires an entity to recognize in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. Management has evaluated the Master Fund’s related events and transactions through the date the financial statements were available to be issued and determined that there were no significant subsequent events that would require adjustment to or additional disclosure in these financial statements.

Capital Accounts

Net profits or net losses of the Master Fund for each month are allocated to the capital accounts of Members as of the last day of each month in accordance with Members' respective investment percentages of the Master Fund. Net profits or net losses are measured as the net change in the value of the net assets of the Master Fund during a fiscal period, before giving effect to any repurchases of interest in the Master Fund, and excluding the amount of any items to be allocated to the capital accounts of the Members of the Master Fund, other than in accordance with the Members' respective investment percentages.

Prior to the end of each quarter, the Master Fund receives Member contributions with an effective subscription date of the first day of the following month.

The Master Fund, in turn, makes contributions to certain Hedge Funds, which have effective subscription dates of the first day of the following month. These amounts are reported as "Contributions received in advance" and "Investments made in advance", respectively.

Management and Incentive Fees

The investment management fee is shared by the Manager and the Sub-Adviser. The Master Fund pays the Manager an investment management fee at an annual rate equal to 1.25% of the Master Fund’s month-end net assets, including assets attributable to the Manager (or its affiliates) and before giving effect to any repurchases by the Master Fund of Member interests. The investment management fee is accrued monthly. The investment management fee is paid to the Manager out of the Master Fund’s assets.

The Manager pays a fee to the Sub-Adviser at a rate equal to 40% of the amount of the fee earned by the Manager pursuant to the Sub-Investment Advisory Agreement.

The Sub-Adviser is entitled to receive a performance-based incentive fee equal to 10% of each Member’s net profits (taking into account net realized and unrealized gains or losses and net investment income or loss), if any, in excess of the non-cumulative “Preferred Return,” subject to reduction of that excess for prior losses that have not been previously offset against net profits (the “Incentive Fee”). The Incentive Fee is calculated and paid at the Feeder Fund level. The Incentive Fee is accrued monthly and is generally payable annually on a calendar year basis. The Preferred Return is a non-cumulative, annual return equal to the weighted average returns of a composite benchmark consisting of 50% of the Barclays Capital U.S. Corporate High Yield Index (Total Return) and 50% of the Credit Suisse Institutional Leveraged Loan Index.

4. Commitments and Other Related Party Transactions (continued)

Administration Fee

U.S. Bancorp Fund Services, LLC (the “Administrator”) acts as the Funds’ Administrator under an Administration Agreement. The Administrator prepares various federal and state regulatory filings, reports and returns for the Funds; prepares reports and materials to be supplied to the Members of the Feeder Funds; monitors the activities of the Funds’ custodian, transfer agent and accountants; coordinates the preparation and payment of the Funds’ expenses and reviews the Funds’ expense accruals. For its services, the Administrator receives a monthly fee from the Master Fund at an annual rate of 0.12% for the first $150 million, 0.10% for the next $150 million and 0.08% thereafter of average net assets, with a minimum annual fee of $100,000.

Expense Reimbursement

The Manager has contractually agreed to waive and/or reimburse the Master Fund’s expenses to the extent needed to limit the Master Fund’s annual operating expenses combined with the annual operating expenses of the Feeder Funds to 2.25% of net assets

for each Feeder Fund. To the extent that the Manager reimburses or absorbs fees and expenses, it may seek payment of such amounts for three years after the year in which the expenses were reimbursed or absorbed. A Feeder Fund will make no such payment, however, if its total annual operating expenses exceed the expense limits in effect at the time the expenses are to be reimbursed or at the time these payments are proposed.

The following is a schedule of when fees may be recouped by the Manager with respect to the Feeder Funds:

City National Rochdale High Yield Alternative Strategies Fund LLC		City National Rochdale High Yield Alternative Strategies Fund TEI LLC		Expiration
$	111,311	$	139,734	March 31, 2017
	8,893		10,803	March 31, 2018
	35,122		37,704	March 31, 2019
	5,439		7,097	March 31, 2020
$	160,765	$	195,338

No accrual has been made for such contingent liability because of the uncertainty of the reimbursement from the Feeder Funds.

5. Investment Risks and Uncertainties

Alternative Investments consist of non-traditional, not readily marketable investments, some of which may be structured as offshore limited partnerships, venture capital funds, hedge funds, private equity funds and common trust funds. The underlying investments of such funds, whether invested in stock or other securities, are generally not currently traded in a public market and typically are subject to restrictions on resale. Values determined by investment managers and general partners of underlying securities that are thinly traded or not traded in an active market may be based on historical cost, appraisals, a review of the investees’ financial results, financial condition and prospects, together with comparisons to similar companies for which quoted market prices are available or other estimates that require varying degrees of judgment.

Investments are carried at fair value provided by the respective alternative investment’s management. Because of the inherent uncertainty of valuations, the estimated fair values may differ significantly from the values that would have been used had a ready market for such investments existed or had such investments been liquidated, and those differences could be material.

6. Concentration, Liquidity and Off-Balance Sheet Risk

The Master Fund invests primarily in Hedge Funds that are not registered under the 1940 Act and invest in and actively traded securities and other financial instruments using different strategies and investment techniques, including leverage, which may involve significant risks. These Hedge Funds may invest a high percentage of their assets in specific sectors of the market in order to achieve a potentially greater investment return. As a result, the Hedge Funds may be more susceptible to economic, political, and regulatory developments in a particular sector of the market, positive or negative, and may experience increased volatility of the Hedge Funds' net asset value.

Various risks are also associated with an investment in the Master Fund, including risks relating to the multi-manager structure of the Master Fund, risks relating to compensation arrangements and risks relating to limited liquidity, as described below.

Redemption restrictions exist for Hedge Funds whereby the Hedge Fund Managers may suspend redemptions either in their sole discretion or other factors. Such factors include the magnitude of redemptions requested, portfolio valuation issues or market conditions.

Redemptions are currently restricted for one Hedge Fund with a fair value of $835,554 at September 30, 2016 as noted in the Schedule of Investments.

6. Concentration, Liquidity and Off-Balance Sheet Risk (continued)

In the normal course of business, the Hedge Funds in which the Master Fund invests trade various financial instruments and enter into various investment activities with off-balance sheet risk. These include, but are not limited to, short selling activities, writing option contracts, contracts for differences, and interest rate, credit default and total return equity swap contracts. The Master Fund's risk of loss in these Hedge Funds is limited to the value of its own investments reported in these financial statements by the Master Fund. The Master Fund itself does not invest directly in securities with off-balance sheet risk.

7. Investment Transactions

For the period ended September 30, 2016 (excluding short-term securities), the aggregate sales of investments were $7,656,094 and there were no purchases.

BOARD APPROVAL OF ADVISORY AND SUB-ADVISORY AGREEMENTS (UNAUDITED)

The Board of Directors (collectively, the “Board”) of each of City National Rochdale High Yield Alternative Strategies Master Fund LLC (the “Master Fund”), City National Rochdale High Yield Alternative Strategies Fund TEI LLC (the “TEI Fund”) and City National Rochdale High Yield Alternative Strategies Fund LLC (together with the TEI Fund, the “Feeder Funds,” and together with the Master Fund and the TEI Fund the “Funds”) is comprised of six Directors, five of whom are independent of the Funds’ investment adviser (the “Independent Directors”).  During the six months ended September 30, 2016, the Board and the Independent Directors approved renewal of the Funds’ advisory agreement with City National Rochdale, LLC (the “Adviser”), and the Adviser’s sub-advisory agreement with PineBridge Investments LLC (“PineBridge”) with respect to the Master Fund, as described below.

General Information

The following information summarizes the Board’s considerations associated with its review of the agreements. In connection with its deliberations, the Board considered such information and factors as the Board members believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. As described below, the Board considered the nature, quality and extent of the various investment advisory and administrative services performed by the Adviser and PineBridge.  In considering these matters, the Independent Directors discussed the approval of the agreements with management and in private sessions with their independent counsel at which no representatives of the Adviser or PineBridge were present.

The Board reviewed extensive materials regarding investment results of the Funds, advisory fee and expense comparisons, financial information with respect to the Adviser and PineBridge, descriptions of various functions such as compliance monitoring and portfolio trading practices, and information about the personnel providing investment management and administrative services to the Funds. The Board also took into account information it received at its past meetings and previous meetings of its committees with respect to these matters.

In deciding to renew the agreements, the Board and the Independent Directors did not identify a single factor as controlling and this summary does not describe all of the matters considered.  In addition, each Board member did not necessarily attribute the same weight to each matter.  However, the Board and the Independent Directors concluded that each of the various factors referred to below favored such approval.

City National Rochdale, LLC

Nature, Extent and Quality of Services

In reviewing the services provided by the Adviser, the Board considered a variety of matters, including the background, education and experience of the Adviser’s key portfolio management and operational personnel; its overall financial strength and stability; its resources and efforts to retain, attract and motivate capable personnel to serve the Funds; and the overall quality and depth of its organization.  The Board also took into account the experience, capability and integrity of the Adviser’s senior management; its investment philosophy and processes, including sub-adviser oversight processes; its portfolio trading and soft dollar practices; its commitment to compliance with applicable laws and regulations and the systems in place to ensure compliance with those requirements; and its disaster recovery, cybersecurity and contingency planning practices.  The Board found all of these matters to be satisfactory.

Investment Performance

The Board assessed the performance of the Feeder Funds compared with their relevant benchmark indexes for the one- and three-year and since inception periods ended June 30, 2016.  The Board members noted that the annualized total returns of the Feeder Funds for the one- and three-year and since inception periods were lower than the returns of the Funds’ benchmark, which was comprised 50% of the Barclays U.S. Corporate High Yield Index and 50% of the Credit Suisse Leveraged Loan Index, by 5.21% or less, 1.7% or less, and 1.48%, respectively.  The Board members considered that the Adviser was satisfied with the Funds’ recent three-month and year-to-date performance and was considering potential manager changes with respect to the Master Fund.  The Board concluded that the Adviser continued to provide satisfactory management and oversight services to the Funds.

Advisory Fees and Fund Expenses

The Board reviewed information regarding the advisory fees charged by the Adviser to the Funds and the total expenses of the Funds (as a percentage of average annual net assets).  The Board noted that it was difficult to gather a peer group for comparison due to the unique investment strategy of the Funds and lack of public information regarding the Funds’ competitors.  The Board reviewed fee and expense information from a broad sample of similarly structured closed-end funds and private funds with alternative investment strategies compiled by U.S. Bancorp Fund Services, LLC, the Funds’ administrator, in consultation with the Adviser, using data from Morningstar, Inc.

The Board observed that the investment advisory fee paid by the Funds was lower than the median fee rate of 100 peer funds employing a similar fund-of-funds strategy.  The Board members noted that the Funds are subject to an incentive allocation in addition to an advisory fee, but that the Funds had not paid incentive allocations for the year ended June 30, 2016. The Board noted that the Adviser does not manage assets of any other clients that have similar investment objectives and policies as those of the Funds. The Board considered that the total expense ratios of the Funds were 0.17% above the median total expense ratio of a peer sample of 16 alternative investment funds that voluntarily report their annual net expense ratios.  The Board concluded that the advisory fees charged by the Adviser to the Funds were fair and reasonable, and the total expenses of the Funds continued to be reasonable.

Profitability, Benefits to the Adviser and Economies of Scale

The Board considered information prepared by the Adviser relating to its costs and profits with respect to the Funds, noting that the Adviser was waiving a portion of its fees with respect to the Funds pursuant to an expense limitation agreement.  The Board determined that the level of profitability was reasonable. The Board also considered the benefits received by the Adviser and its affiliates as a result of the Adviser’s relationship with the Funds (other than investment advisory fees paid to the Adviser), including fees paid to the Adviser’s affiliate, RIM Securities, LLC, for providing distribution services to the Funds; benefits to the Adviser’s general wealth management business as a result of the availability of the Funds to its customers; and the intangible benefits of the Adviser’s association with the Funds. The Board noted the Adviser’s representation that no significant economies of scale with respect to the Funds had been realized in the last year. The Board also noted that although there were no advisory fee breakpoints in the Funds’ advisory fee schedules, based on the Adviser’s operations, significant economies of scale were not likely to be realized until the asset levels of the Funds were significantly higher than their current levels.

Conclusions

Based on their review, including their consideration of each of the factors referred to above, the Board and the Independent Directors concluded that the compensation payable to the Adviser with respect to the Funds pursuant to its advisory agreement with the Funds is fair and reasonable in light of the nature and quality of the services being provided by it to the Funds and their respective shareholders, and that renewal of the agreement was in the best interest of the Funds and their respective shareholders.

PineBridge Investments LLC

Nature, Extent and Quality of Services

In reviewing the services provided by PineBridge, the Board considered a variety of matters, including the background, education and experience of PineBridge’s key portfolio management and operational personnel; its overall financial strength and stability; its resources and efforts to retain, attract and motivate capable personnel to serve the Master Fund; and the overall general quality and depth of its organization. The Board also took into account the experience, capability and integrity of its senior management; its investment philosophy and processes; PineBridge’s investment operations and staff; its portfolio trading and soft dollar practices; its commitment to compliance with applicable laws and regulations and the Funds’ compliance policies and procedures; and its disaster recovery, cybersecurity and contingency planning practices.  The Board found all of these matters to be satisfactory.

Investment Performance

The Board’s observations regarding the performance of the Funds are described above.  The Board concluded that PineBridge continued to provide satisfactory services to the Master Fund.

Advisory Fees and Fund Expenses

The Board reviewed information regarding the sub-advisory fees charged by PineBridge and observed that PineBridge does not advise any other funds of hedge funds with investment strategies similar to the Funds and therefore it could not compare PineBridge’s sub-advisory fees with the fees PineBridge charges to other similar clients.  The Board noted that the Adviser pays out of its advisory fees all sub-advisory fees to PineBridge.

Benefits to PineBridge

The Board considered the benefits received by PineBridge as a result of its relationship with the Funds (other than sub-advisory fees paid to PineBridge), including the intangible benefits of PineBridge’s association with the Funds generally and any favorable publicity arising in connection with the Funds’ performance.  The Board also considered that the asset levels of the Funds were relatively small and were currently not likely to lead to significant economies of scale.

Conclusions

Based on their review, including their consideration of each of the factors referred to above, the Board and the Independent Directors concluded that the compensation payable to PineBridge pursuant to its sub-advisory agreement is fair and reasonable in light of the nature and quality of the services being provided by PineBridge to the Funds and their respective shareholders, and that renewal of the sub-advisory agreement was in the best interest of the Funds and their respective shareholders.
