History and Ownership Altair Advisers was formed on June 1, 2002. It was created with an exclusive focus on providing investment counsel to high net worth individuals, families and foundations. We believe that providing investment and financial advice is a separate and distinct business from the selling of investment products. Altair’s principals formerly led the Investment Advisory Services practice of Arthur Andersen’s Chicago office. We serve a nationwide base of clients who have entrusted us to oversee more than $8.6 billion (as of December 31, 2024). Altair is primarily employee-owned and committed to building long-term successful relationships by providing responsive and highly personal service. The employee group participates broadly in Altair’s ownership. One of the firm’s owners is an entity controlled by a client who helped fund the firm at its inception. The client which controls this entity does not, nor has requested to, receive preferential treatment, aside from access to financial and operational information about the firm and other rights customarily provided to an investor in any business. What We Do Altair’s core investment consulting services include: investment policy creation, asset allocation advice, investment manager due diligence and portfolio management services. We also provide performance reporting, capital sufficiency analysis and cash flow management for all investment consulting clients. ALTAIR’S SERVICE APPROACH Altair first works with the client to develop an overall investment strategy. This phase of the process includes an analysis of financial goals, which generally considers advice regarding capital sufficiency and cash flow, retirement planning, income tax planning, education funding, corporate benefit decisions and consideration of estate planning. The result of this overall analysis serves as the foundation for a client's strategic investment plan, which includes investment education, portfolio design and preparation of an Investment Policy Statement. After developing an overall strategy documented in a written Investment Policy Statement, for discretionary clients, Altair will be directly responsible for making investment decisions on behalf of those clients. For non-discretionary clients, Altair will obtain a client's consent before making an investment decision on behalf of those clients. For both discretionary and non-discretionary clients, the client’s assets will be invested with various third-party investment managers, mutual funds (potentially including mutual funds for which Altair serves as investment adviser, as described below), Exchange Traded Funds (“ETFs”), private investments and derivatives. For assets where there is not a predetermined list of investment options, Altair will only utilize those third-party managers, mutual funds, ETFs, private investments or derivatives after it has conducted due diligence on each recommendation for investment (“Altair assets”). For client assets that have pre-determined investment choices (e.g., inside a client’s 401(k) plan), Altair will assist the client with regard to those choices to the extent permitted and practicable (“outside assets”). Altair serves as investment adviser to the Adara Smaller Companies Fund and Aquarius International Fund of the RBB Fund, Inc. (each a “Fund” and collectively the “Funds”), each an investment company registered under the Investment Company Act of 1940, as amended. Altair expects only select individuals and entities known to Altair to be shareholders of the Funds, including Altair clients, employees and other related parties. Altair often recommends each Fund as an investment vehicle for its clients, including clients governed by the Employee 1  Retirement Income Security Act (“ERISA”). Altair has adopted the following practices and controls in recommending each Fund to its clients subject to ERISA: • As more fully described in Item 5 below, Altair does not charge a separate fee for managing the Funds; • The ERISA plan will not pay any sales commission or redemption fee related to investments in the Funds; and • Altair will obtain approval to invest the client’s assets in each Fund from an independent fiduciary of the ERISA plan after providing information about each Fund to the independent fiduciary, including a description of: a) fees paid; b) Altair’s rationale for recommending each Fund as a suitable investment; and c) any limitations related to the timing of purchases and withdrawals. As described more fully within the prospectus, the Funds utilize a “multi-manager” approach whereby the Funds’ assets are allocated to one or more third-party advisers (“Sub-Advisers”) in percentages determined by Altair. Each Sub-Adviser acts independently from other Sub- Advisers and utilizes its own distinct investment style in selecting securities. However, each Sub-Adviser, under the oversight of Altair, operates within the constraints of each Fund’s investment objective and strategies and the particular investment restrictions applicable to that Sub-Adviser. Altair does not provide investment services related to specific securities or sectors other than: (a) to recommend various third-party investment managers, mutual funds, ETFs, private investments and derivatives; and (b) in connection with its role as adviser to the Funds. Altair will be responsible for arranging the execution of the investment decisions for its discretionary clients. For its non-discretionary clients, Altair will arrange the execution of the investment decision only after it receives authorization to do so from the client. Clients can impose restrictions with respect to specific securities or types of securities in the accounts managed by third-party investment managers. In addition, Altair typically provides administrative services to both its discretionary and non- discretionary clients, including transferring assets between a client's accounts. For clients who have invested their assets in private investment vehicles that make additional capital calls, Altair generally has limited discretion to respond directly to such capital calls without the need to first seek client authorization. Specifically, Altair will process the capital call by transferring assets to the investment vehicle directly from the client's account. Further, should a client's account not have sufficient cash to fund the capital call, Altair's limited discretion would give it the ability to dispose of holdings/investments in the client's account sufficient to meet the capital call. Altair also provides consulting and investment advisory services to retirement plans, trusts, estates, charitable organizations, corporations or other business entities. Typical services provided to these clients are consistent with the process described above. As described within Item 19, Altair works with a third-party vendor which provides class action litigation monitoring and securities claim filing services. This vendor will complete claims for all of our clients who do not opt out of such a service. In return for this service, the vendor receives a percentage of any settlement collected. Altair does not receive a payment for services provided by the third-party vendor, aside from its negotiated investment management fees for managing Altair assets as described within Item 5 below. Altair is not responsible for class action or similar legal litigation matters related to the Funds. 2  SERVICES FOR LIMITED FINANCIAL PLANNING CLIENTS Altair provides financial planning services in addition to investment advisory services. Financial planning services include an analysis of financial goals, which generally considers advice regarding capital sufficiency and cash flow, retirement planning, income tax planning, education funding, corporate benefit decisions and estate planning matters. Altair is at times retained by a corporation to provide these financial counseling services to key officers and executives of the corporation and to provide financial planning seminars and other educational services to groups of employees. PROJECTS Altair will provide other limited, negotiated services as an accommodation to clients, as agreed to by Altair. ASSETS UNDER ADVISEMENT As of December 31, 2024, Altair had total assets under advisement of $8,681,860,723. Of this total, $3,977,273,186 were managed on a discretionary basis and $4,704,587,537 were managed on a non-discretionary basis. ITEM 5 – FEES AND COMPENSATION Fees for Altair’s services are documented in a written engagement contract at the inception of each engagement. While we generally do not negotiate fees, we will negotiate fees in certain circumstances based primarily on the size of the account and relationship with Altair. Fees for Investment Advisory Clients In the case of investment advisory services clients (i.e., for both Altair assets and outside assets), Altair will at times charge fees for the first phase of services, which includes developing a strategic investment plan. These fees are determined based on the complexity of the client's situation and the scope of the work involved. If there is a fee for this phase it is generally billed as a one-time project fee. Fees for the second phase of services, including implementation and ongoing portfolio review, are generally calculated based on a percentage of client assets under advisement and are payable quarterly in advance. Assets under advisement include those mutually determined and agreed upon with the client and Altair. Our current standard fee schedule is: Fees as a Percentage of Assets Assets Subject to Fee 0.80% on the first $5 million plus 0.50% on the next $15 million up to assets of $20 million plus 0.35% on the next $30 milion up to assets of $50 million plus 0.25% on the next $50 million up to assets of $100 million plus 0.10% on the assets above $100 million Altair has had other fee schedules in effect during the time it has been in business that could be lower or higher than those outlined above. Based on the fee schedule in effect at the time of engagement and the size of a particular account, Altair clients will probably pay different fees. Altair manages client accounts based on their investment goals, regardless of their fees. While Altair’s fee schedule creates an incentive to encourage clients to remain invested, Altair follows 3  investment guidelines created with the client and documented within an investment policy statement in advising that client. Altair imposes a minimum annual fee of $50,000 which increases by 3% every four quarters. This minimum will be reduced under certain limited circumstances and/or certain long-time clients are “grandfathered” under a prior fee arrangement. Altair deducts fees directly from the client’s account, unless otherwise mutually agreed upon. Altair generally does not take into consideration cash flows occurring during the subsequent quarter when calculating fees except in unusual circumstances (such as in connection with a new client account or a substantial new cash flow as agreed upon with the client). As agreed upon between Altair and the client, Altair generally consolidates fees for accounts under the same household for fee billing purposes. Fees to Altair do not include any fees due to various third-party investment managers, mutual funds, ETFs, private investments and derivatives, any fees due to brokers or to custodians of those assets or the fees associated with outside assets (e.g., 401(k) fund fees). Such charges, fees and commissions are exclusive of and in addition to Altair’s fee, and these fees will vary based on the nature of the investment vehicle. Clients considering an investment in private investment funds offered by third-parties should consult the applicable offering documents as the authoritative source for a description of fees to be charged. Further, Altair strives to recommend that its clients invest in the lowest mutual fund share class available to the client, though that share class does not always represent the lowest share class available to other shareholders as determined by the mutual fund’s sponsoring company. Neither Altair nor any of its supervised persons receive any portion of the commissions or fees clients pay to any recommended investment manager, mutual fund, ETF, private investment or derivative broker or custodian. See Item 12 for a discussion of our brokerage practices. Owners of Altair are eligible to use its services free of charge, and some family members of employees receive fee discounts. Clients could obtain access to these same investment managers, mutual funds, ETFs, private investments and derivatives directly without going through Altair. However, in order to do so, we believe they would likely have to invest at a substantially higher minimum investment and/or pay higher management fees associated with such investments. Other financial planning-related projects are billed in a manner agreed upon by Altair and the client. Accounts initiated or terminated during a calendar quarter are charged a prorated fee. Upon termination of any account, any prepaid, unearned fees are refunded to the client. Fees for Limited Financial Planning Clients As described in Item 4, Altair also provides financial planning services. When we are retained by a corporation to provide financial counseling services to key officers and executives of the corporation (collectively, “executives”), fees are generally charged to the corporation based on a fixed-fee entitlement arrangement for each executive dependent on the scope and complexity of the services being performed. Altair's fees generally range from $5,000 to $30,000 per executive participant. When we are retained by a corporation to provide financial planning seminars and other educational services to groups of employees, fees for these services are based on fixed-fee arrangements as negotiated with the corporation. Fund Fees Altair does not receive any compensation from the Funds. Altair’s fee structure for services provided to the Funds is found in each Fund’s prospectus. Altair created each Fund as a vehicle for its clients to access investment managers otherwise unobtainable to most of its clients due to account minimums. Each Sub-Adviser’s management fee, as well as other 4  expenses described within the prospectus (legal, compliance and record-keeping), are charged directly to each applicable Fund, and such expenses are borne by all shareholders of that Fund. Client assets invested in the Funds are generally included in the calculation of the fee for ongoing investment advisory services described above. Project Fees At times, fees are charged based on hourly rates, which vary from $200 to $500 per hour. At other times, fees are charged on a project basis. Project fees generally apply to all types of clients and will be negotiated for each unique engagement in advance of beginning project work. Valuation Practices Altair uses market values for publicly-traded securities as provided by Altair clients’ custodians to determine fees and investment performance returns. In determining the market value to use, Altair ranks client custodians by total client assets held, and uses the prices provided by the custodian with the largest amount of client assets held. If that custodian does not provide a price, Altair defers to other custodians within the hierarchy until a custodian offers a price deemed reasonable. Altair obtains values of private funds deemed to be liquid from the investment manager or the private funds’ administrators. Altair considers private funds to be liquid if the investor can routinely invest in or redeem from the fund subject to known constraints identified within the private fund’s offering documents. As a matter of policy, Altair does not determine the prices of private funds considered to be illiquid in nature. Rather, Altair uses either; 1) capital balance statements provided by the private fund’s investment manager once they are available (generally, after a few quarters following the first capital call); or 2) the sum of capital calls prior to a capital balance statement being made available by the investment manager. Given the inherent limitations associated with receiving the necessary information from the investment manager, the values provided by the investment manager often represent a lag of up to 150 days or more. In the unlikely event an Altair pricing source outlined above is not able to, or does not, provide a price for an asset held in client portfolios, Altair will value the asset via alternative sources deemed reliable, including external pricing sources or determining a fair value for the asset with input as appropriate from a Sub-Adviser. In determining a fair value, Altair will strive to value the asset at a price Altair deems clients could reasonably be expected to receive upon sale of the asset. Altair encounters inherent conflicts of interest when it participates in the valuation of client accounts, as higher values of client holdings increase market values, thereby enhancing performance results and increasing fees. Altair maintains various policies, procedures and controls (including a valuation policy and segregation of duties) to mitigate such conflicts of interest. ITEM 6 – PERFORMANCE-BASED FEES AND SIDE-BY-SIDE MANAGEMENT Altair does not charge any performance-based fees (fees based on a share of capital gains on or capital appreciation of the assets of a client). 5  ITEM 7 – TYPES OF CLIENTS As described in Items 4 and 5, Altair provides portfolio management services to high net worth individuals, families, foundations and endowments. In a few select cases where there is a direct client connection, Altair provides investment advisory services for corporate pensions, profit sharing plans and charitable organizations. Altair has an initial investment minimum of $7 million and a minimum annual fee of $50,000 for ongoing investment advisory services (which increases by 3% every four quarters). In certain circumstances, exceptions to these minimums are made; for example, where the owner of the account has a familial relationship with an existing client or where the prospective client is expected to meet the initial investment minimum in the near future. In addition, certain long- time clients are “grandfathered” under a prior fee arrangement. Various third-party investment managers, mutual funds, ETFs, private investments and derivatives impose investment minimums that will likely impact the client’s investment selection process. Minimum investment requirements for investment in a Fund are found in that Fund’s prospectus. Altair’s investment management agreement with the client determines the protocol the client or Altair will follow in terminating accounts. Altair and its personnel maintain separate relationships with certain clients and others, such as: • Select clients, vendors or other service providers used by firm clients are family members or personal friends with firm personnel. As such, these clients maintain separate personal relationships with firm personnel. At times, firm personnel will engage in personal business dealings with these clients as a natural extension of their personal relationships. • Some clients are affiliated with entities which have a business relationship with the firm (such as firm vendors or other service providers used by firm clients), and certain of these entities have engaged us to manage their investment portfolios. • Subject to advanced clearance, Altair employees are permitted to invest in financial entities affiliated with clients, such as venture capital or similar funds. • As noted within Item 11 below, Altair employees are permitted to accept gifts from certain vendors deemed to be lower risk in nature. To address these potential conflicts of interests, all relationships with vendors are designed to be arms’ length in nature, and gifts received are determined to not impact Altair’s decision- making processes. Altair also maintains policies and procedures designed to ensure clients are treated fairly as summarized within this disclosure document. Further, all client relationships are managed following a team approach, with no one employee responsible for any individual client’s account. We have an incentive to encourage individual clients to rollover an employer retirement account into an Altair-managed Individual Retirement Account (“IRA”). The decision of whether to rollover an employer retirement account rests with the individual account owner, and we are committed to providing information to help a client make a decision that is in that client’s overall best interests. When we provide investment advice to you regarding your retirement plan account or individual retirement account, we are fiduciaries within the meaning of Title I of the Employee Retirement Income Security Act and/or the Internal Revenue Code, as applicable, which are laws governing retirement accounts. The decision to recommend rolling over a retirement account to an Altair- managed account creates a conflict of interest, so we operate under a specific rule that requires us to act in your best interest and not put our interest ahead of yours. 6  ITEM 8 – METHODS OF ANALYSIS, INVESTMENT STRATEGIES AND RISK OF LOSS Methods of Analysis Rather than selecting individual stocks and bonds, Altair focuses on finding best-in-class investment managers, including Sub-Advisers to manage the Fund’s assets. The process of selecting investment managers and funds is described below. PROCESS FOR ALTAIR ASSETS (WHERE INVESTMENT CHOICES ARE NOT PRE- DETERMINED E.G., CLIENT-DIRECTED OR LIMITED OPTIONS WITHIN A 401(K) OR OTHER PLAN) SETTING AN AGENDA Altair’s Investment Committee begins by identifying and approving research projects for new or existing asset classes and oversees full reviews of our currently recommended investment managers, mutual funds, ETFs and private investments. A full review of each asset class is done regularly, generally every three years. QUANTITATIVE SCREENS Once a particular search is initiated, Altair’s research team pre-screens third-party databases to examine those strategies that meet basic quantitative requirements. We have a preference for investment managers, mutual funds, ETFs and private investments with relatively strong risk adjusted returns and generally at least five years of return history. QUALITATIVE SCREENING We focus our efforts during this stage on the investment managers, mutual funds or private investments to remove those that have undesirable attributes, such as holding too many securities in their composite portfolio, poor historical after-tax returns, excessive assets relative to the strategy or insufficient total firm assets under management. Those that pass the general qualitative screens are then examined more thoroughly. Considerations include the growth of the sponsoring firm’s total assets over time and the fundamentals of the portfolio. These factors vary based on asset class. For example, when examining an equity product, these include price-to-equity ratio, price-to-book ratio and weighted-average market cap. A rolling returns-based style analysis is used to eliminate investment managers, mutual funds, ETFs or private investments that have changed in investing style over time. Then a detailed questionnaire is sent to potential candidates in order to gather more information. After reviewing all data and information, the Investment Committee selects the candidate firms which it believes merit an onsite visit by an Altair investment professional. Ultimately, Altair’s Investment Committee will be presented with finalists to be considered for potential inclusion on our recommended list. In addition to the above, when evaluating private investments, we will review the legal structure of the investments, funding and withdrawal provisions. Altair uses an industry leading vendor in the field of investigative due diligence to delve into the background of the principals of the private investment firm. We also rely on the insights and opinions of consultants, appraisers, accountants, lawyers, and industry sources as needed. PROCESS FOR OUTSIDE ASSETS (WHERE INVESTMENT CHOICES ARE PRE- DETERMINED E.G., CLIENT DIRECTION OR LIMITED OPTIONS WITHIN A 401(K) OR OTHER PLAN) 7  Altair will assist clients with the selection of investment options where predetermined choices are provided as follows: • We recommend any fund which is already subject to due diligence as described just • • above in “Process for Altair assets (where investment choices are not pre-determined e.g., client directed or limited options within a 401(k) or other plan)”. If no investment choices exist which fulfill this requirement, then we will recommend index funds which complement a client’s asset allocation. If no investment choices exist which fulfill this requirement, we will review the investment options and make a recommendation based on fit within the client’s overall asset allocation strategy, historical performance and information known at the time about the fund. Altair does not offer extensive and ongoing due diligence on the universe of predetermined options for each plan where we assist our clients by making an investment recommendation. We rely on clients to provide updated information on the list of predetermined investment options from time to time for review and recommendations. We include these outside assets in a client’s performance report when a client agrees that these assets should be part of our engagement. We will recommend a change to a different option within the allowable investment choices when appropriate. Investment Strategies Altair believes it is crucial to listen to clients and understand their goals and objectives prior to making any investment recommendations. We then create an investment portfolio designed to achieve those goals and objectives in a risk-controlled manner. When recommending a portfolio strategy, we recognize the importance of asset allocation and diversification but also consider the principles of behavioral finance and investor psychology. As historical events demonstrate so vividly, it is imperative to understand the relationship between risk and return and to understand the degree to which portfolio declines can be tolerated. Altair’s investment process can be described as a strategic asset allocation approach with a tactical overlay. We create and implement long-term strategic investment plans that are appropriate for each client’s financial objectives, risk preference and constraints. However, on an ongoing basis we will recommend overweights and underweights to certain asset classes based on our proprietary research and valuation methodology. In other words, while we believe strategic asset allocation works best over long periods of time, we also believe allocation modifications are warranted under certain circumstances. Altair’s Investment Committee is responsible for all investment recommendations with regard to both asset allocation and investment managers. The Investment Committee currently consists of five members with, on average, over 30 years of investment experience. Altair does not advertise that it will manage accounts or invest in securities based on Environmental, Social and Governance (“ESG”) criteria. However, Altair will consider prospect or client-specific ESG guidelines or restrictions on a case-by-case basis. Risk of Loss Any investing involves risk of loss that clients should be prepared to bear. We do not offer any products or services that guarantee rates of return on investments for any time period. MUTUAL FUNDS AND EXCHANGE TRADED FUNDS Mutual fund and ETF shareholders are subject to various inherent risks applicable to all shareholders, including inherent risks associated with the individual issuers of each fund’s underlying portfolio securities. Please see each fund’s prospectus for a more detailed description of that particular fund’s risks. 8  While shares of ETFs generally trade on the market at or near their most recent NAV, certain inefficiencies could cause ETF shares to trade at a premium or discount to the calculated NAV. ETFs redeem shares which are aggregated as creation units comprised of a minimum number of shares. As such, shareholders of ETFs would likely be limited in their ability to dispose of shares held if a liquid secondary market ceases to exist for shares of a particular ETF. Closed-end funds, unlike open-end mutual funds, trade on the market, generally at a premium or discount to NAV based on various market factors. Purchasing shares of a closed-end mutual fund at a discount does not guarantee a profit, as there can be no assurance the closed-end mutual fund’s market price will subsequently revert to the fund’s calculated NAV. THIRD-PARTY INVESTMENT MANAGERS While Altair conducts ongoing due diligence of third-party investment managers, the successful implementation of a client’s objectives related to assets managed by a third-party investment manager is dependent upon the third-party investment manager’s ability to successfully implement its investment strategies. In addition, Altair is not an affiliate of any third-party investment manager and, therefore, is not in a position to supervise the third-party investment manager’s activities. PRIVATE POOLED INVESTMENT VEHICLES Managers of private funds and other private pooled investment vehicles (including hedge funds and private equity funds) often have broad discretion in managing the portfolios, and such private funds are generally not registered with the SEC. Private funds are invested in a variety of financial instruments (including derivatives and other leveraged financial instruments) following a variety of strategies (including trading on margin with no obligation to diversify), resulting in potentially greater risks than publicly registered investment vehicles. Investors in such private pooled investment vehicles are advised to refer to each fund’s offering documents for a greater description of the fund’s risks. Altair is not an affiliate of any third-party private fund and, therefore, is not in a position to supervise the third-party private fund’s activities. EXCHANGE TRADED DERIVATIVES The use of exchange traded derivatives for a client account might create additional investment risk if the instrument does not correlate well with the index or if Altair's view of the market is incorrect. In addition, the use of derivatives might expose the client to leverage risk, which would likely magnify or otherwise increase the risk of investment losses. ADARA SMALLER COMPANIES FUND AND AQUARIUS INTERNATIONAL FUND Clients investing in a Fund should carefully read each prospectus for risks specific to that Fund. Sub-Advisers will invest primarily in equities and equity-related instruments of small and micro- cap companies for the Adara Smaller Companies Fund and international securities for the Aquarius International Fund, including common stocks, preferred stocks, convertible securities, sponsored and unsponsored depositary receipts, warrants and rights. MARKET RISKS The success of our recommendations depends to a great extent upon the future course of the financial markets’ price movements of various investment vehicles, which very much not within our control. ARTIFICIAL INTELLIGENCE RISKS Altair uses artificial intelligence large language models (“LLMs”) to enhance the efficiency of certain internal business processes. Select third-party investment managers (including Sub- Advisers) use artificial intelligence tools in various fashions to improve their investment management processes, subject to their internal policies and oversight. While these tools enhance efficiency and provide valuable insights, they also present risks. Artificial intelligence tools, such as LLMs, may produce outputs that are inaccurate, incomplete, or biased because of their training on diverse datasets. 9  INFLATION RISKS Inflation represents the increase of goods and services over time, and acts to decrease the real value of your investments. We have no control over inflation, and there can be no assurance client investment portfolios will keep pace with the rate of inflation. ITEM 9 – DISCIPLINARY INFORMATION Altair has no events or information applicable to this Item. ITEM 10 – OTHER FINANCIAL INDUSTRY ACTIVITIES AND AFFILIATIONS As described in Item 4 above, Altair serves as investment adviser to the Adara Smaller Companies Fund and Aquarius International Fund of the RBB Fund, Inc. Altair is not affiliated with other financial services entities. Select employees of Altair hold all shares of Zembra Investments LLC (“Zembra”). Zembra serves no other purpose than to invest in units of Altair. Select Altair employees serve on Advisory Boards for third-party private funds, subject to advanced approval and ongoing reporting obligations. Altair has determined permitting employees to serve on certain Advisory Boards is in the best interests of the firm and its clients as: a) the employee’s Advisory Board involvement will provide additional insight into the fund and its manager’s staff; and b) the employee’s interaction with peers at the firm will provide additional growth opportunities and experiences for the employee. In considering whether to approve the employee’s participation on an Advisory Board, Altair considers, among other matters, whether the third-party fund manager’s compliance program is deemed to be adequate and effective to prevent the Altair employee from receiving proprietary information about the fund manager’s current or planned trading activity. The employee also does not receive compensation for participation on the Advisory Board and does not vote or participate in any decision regarding Altair’s use of the third-party fund or its manager. Further, Compliance considers the employee’s role on an Advisory Board in reviewing the employee’s personal trading activity. Altair at times receives reimbursement for employee travel costs from sponsors of conferences at which Altair employees are featured speakers or panelists. ITEM 11 – CODE OF ETHICS Altair invests in money market funds, mutual funds and ETFs within its corporate reserve accounts to manage operating capital. Employees are eligible to (and do) invest with the third- party investment managers, mutual funds (including the Adara Smaller Companies Fund and Aquarius International Fund), ETFs, private investments and derivatives which are also recommended to clients. Our recommendations are not time sensitive and are intended to be durable in nature. We will recommend that clients who implement portfolios at different times invest with similar investment managers, mutual funds, ETFs and private investments. We are not concerned when an investment is made as we view each recommended investment as beneficial to the portfolio over the long term. Thus, the timing of an investment is not central to our recommendations or investment strategies. Though we will recommend underweighting and overweighting various asset classes from time to time, the underlying recommendation of investment managers, mutual funds, ETFs and private investments is relatively consistent across time. 10  Altair at times recommends investment opportunities with a limited supply (generally, private investment vehicles available to qualified purchasers). As noted in Item 12, Altair maintains a policy which outlines the process followed to provide eligible clients the option to invest in such limited investment opportunities. If the investment opportunity has sufficient supply remaining after offering the opportunity to eligible clients, Altair employees who are eligible to participate in such limited investment opportunities (owners and directors) are permitted to do so, and are not subject to any minimum investment Altair generally imposes on client accounts to participate within such limited investment opportunities. These minimum investment requirements for clients to invest in a limited investment opportunity are designed to protect the client’s portfolio. Eligible clients are always offered the opportunity to participate in limited investment opportunities ahead of Altair employees, and will be liquidiated ahead of or at the same time as employee liquidiations in the event Altair determines to recommend clients liquidate holdings of the investment. In practice, Altair owners and directors invest alongside clients within private investment vehicles. Altair has adopted a written Code of Ethics that governs the personal securities transactions of employees and officers. The Code of Ethics permits Altair's employees to engage in other securities transactions. Thus, officers and employees purchase individual securities which at times are also be purchased by the independent, third-party investment managers retained by Altair's clients (including Sub-Advisers to the Funds). Since, as discussed above, our advice is not time-sensitive, but intended to be durable and long-term in nature, Altair employees are permitted to purchase or sell any securities for their own accounts prior to, simultaneously with or subsequent to any action taken in a client portfolio or in an investment manager account. Officers and employees, including members of the Investment Committee, are also permitted to invest their personal holdings in a manner which is not consistent with Altair’s advice provided to clients. Further, Altair employees have no advanced knowledge of third-party investment manager trading activity. Since we are not portfolio managers in the traditional sense of buying and selling individual securities for client accounts and we do not have knowledge of trades placed by third-party investment managers until after they occur, we do not believe the personal investing activities of our officers and employees create a conflict of interest with our clients. Altair's Code of Ethics requires individuals to report required personal securities transactions on a quarterly basis to Altair's compliance personnel. Altair does not require employees to report transactions in certain types of investments, including direct obligations of the United States Government, accounts over which the employee has no discretionary authority, direct obligations of the United States Government, short-term instruments, automatic investment plans and direct investments in currency (including cryptocurrency). Altair’s inherent business model results in Altair employees periodically receiving material nonpublic information from clients regarding their employers. Altair’s Code of Ethics restricts trading by employees in securities where clients are insiders. As described in Item 4 above, Altair serves as the investment adviser to the Funds, and recommends most clients to invest in the Funds. Our Code outlines the standards of conduct we expect of Altair employees and includes limitations on outside business activities of employees and giving/receiving gifts. Outside Business Activities are generally prohibited; any exception requires advanced approval by Compliance. While we believe the proper use of business entertainment and gifts creates goodwill and aids in the development of strong working relationships, as a matter of policy, we strive to not offer nor receive business entertainment or gifts which could be viewed as influencing the recipient’s investment decision-making process or making the recipient feel beholden to any client, prospective client, broker, third-party manager, or investment management-focused vendor. 11  We maintain a policy which prohibits employees from receiving gifts from investment management-focused vendors or suppliers, clients, prospective clients, brokers or third-party investment managers, except those extended as a customary courtesy. Altair employees are permitted to accept gifts from vendors or suppliers who are not investment management- focused so long as the nature of the gift is not viewed as being: 1) overly generous; or 2) aimed at making the employee feel beholden to the entity. Our policy also prohibits employees from soliciting gifts, benefits or gratuities at any time, and places limitations on our employees’ abilities to give gifts to those with which Altair has a business relationship. A copy of the Code of Ethics will be furnished to any client or prospective client upon request. ITEM 12 – BROKERAGE PRACTICES For clients that have provided Altair with trading authorization, we generally process transactions for the sale and/or purchase of securities and other investments in the client's account solely through the client's custodian-affilated broker. Under these circumstances, Altair does not have any obligation to seek better execution services or prices from other possible brokers or dealers. Altair generally does not aggregate client transactions for execution, which might cause the client to incur higher fees than they otherwise would have incurred if the trade had been affected in aggregation with other clients. However, Altair at times will choose to aggregate (or “block”) trades within client accounts of the same family when aggregating trades is deemed to be in the best interest of participating clients. All accounts participating in the aggregated order receive an average share price with transaction costs shared pro rata based on each account’s participation in the transaction. Altair views each recommended investment as beneficial to the portfolio over the long term and, as such, the timing of an investment is not central to our recommendations or investment strategies. Altair arranges the execution of the investment decisions for non-discretionary clients only after it receives authorization to do so from the client. As such, non-discretionary client accounts will generally trade the same security after discretionary client accounts, and non- discretionary clients will likely pay more or less than other discretionary clients for the same security, due to market trading activity. Principals of the firm often recommend that clients retain those custodians or brokers that have agreed to preferred pricing arrangements for Altair clients such that all negotiated terms directly benefit the client through enhanced services or reduced fees. Recommended brokers or custodians are not necessarily the lowest-cost provider, but are those that Altair believes are competitively priced for the level of service provided. Not all advisers recommend custodians or brokers to their clients. However, a client is free to retain any custodian or broker dealer they choose. While Altair is able to realize operational efficiencies by having its clients’ assets reside with a limited number of custodians, Altair-recommended brokers or custodians are selected based on Altair's consideration of the broker or custodian's general reputation, level of services provided, competitiveness of fees or special expertise. Altair generally recommends custodians to clients that have demonstrated the ability to provide our clients with discounted transaction charges, preferred access to certain mutual funds, including lower sales charges than for direct purchases and lower minimum purchase amounts, and the ability to custody and safeguard derivative investments. These same benefits are made available to Altair's principals and employees. The benefits to Altair and its principals and employees are not a material factor in determining which brokers to recommend; rather, the primary considerations are the services provided to the client. Altair does not expect that clients will pay commissions to the custodian-affilated brokers we recommend that are higher than 12  those obtainable from other brokers for comparable client services, although there can be no assurance that clients will pay the lowest possible commissions available. While we do not receive cash compensation or research (typically referred to as “soft dollar” payments) from custodian-affiliated brokers we recommend to clients, we receive other services from these entities, including: • Complimentary admittance for our employees to attend seminars and conferences (though we do not receive travel or reimbursement for other expenses related to attending these conferences); • Practice management consulting services paid for by the custodian (such as consulting fims which track client experiences); and • Practice management communications generally available to advisers with clients on the custodian’s platform. On occasion, Altair has received (and in the future may receive) additional payments from such custodians solely to reimburse Altair for the costs that Altair has incurred (or will incur) directly resulting from the custodian’s internal systems changes or updates that directly impacted (or will impact) Altair’s systems and its ability to service its client(s) that have selected that custodian. Such one-time payments do not impact Altair’s analyses as to whether to recommend (or not) that a client retain that custodian. Altair at times recommends investment opportunities with a limited supply (generally, private investments available to qualified purchasers). Altair maintains a list of clients who are eligible to invest in such limited investment opportunities, and are offered the opportunity to invest in sequential order. If a client is unable to participate in one opportunity, that client will remain on the list and will be able participate in future limited investment opportunities, as dictated by the client’s fixed order on the list. In the event Altair identifies a transaction error has occurred in a client’s account, Altair will work with the custodian promptly to correct, limit or mitigate the effect of the transaction error, with the objective of making the client whole. If necessary, Altair will reimburse clients following a transaction error committed by Altair, at times by reducing or waiving future fees to be paid to Altair. Altair will pay former clients any remaining balance due upon termination of the client relationship. At other times, Altair will work with the client’s custodian to adjust the trades to the correct transaction error in the client account, with Altair settling any difference with the custodian outside of the client’s account. Altair generally considers a “transaction error” to be the execution of a trade or transaction by Altair on behalf of a client on terms other than those intended by Altair or the client, as applicable. Altair faces an inherent conflict in addressing transaction errors, as transaction errors are often detected by Altair personnel who have an inherent incentive to mitigate such transaction errors in Altair’s favor, to the detriment of the clients. To address this risk, Altair logs and Altair management reviews all transaction errors. Altair believes these controls, along with Altair’s periodic employee training program, function to mitigate these inherent risks. ITEM 13 – REVIEW OF ACCOUNTS Directors of Altair are responsible for reviewing the strategic investment plan, the client's overall financial situation and the performance of the client's portfolio. The number of clients assigned to each Director and Managing Director varies according to the complexities of each individual client account. Accounts are reviewed on a quarterly basis, which includes the delivery of written performance reports to clients. These reports provide a review of the client's investment portfolio, including a 13  review of asset allocation, performance comparisons for the client's investment managers and commentary on general market conditions. Generally, each account is reviewed with the client at least semi-annually. Altair, along with the Funds’ third-party service providers that provide compliance, administration and accounting services, actively monitors transactions and holdings for compliance with the Funds’ investment restrictions. ITEM 14 – CLIENT REFERRALS AND OTHER COMPENSATION Other than as described in Item 5 and the limited benefits received from client custodians disclosed in Item 12 above, Altair does not receive cash compensation or other economic benefits in connection with providing advice to clients. We maintain relationships with various third parties (both individuals and entities such as attorneys or accountants), and we at times receive referrals from these third parties. We also periodically refer clients to other service providers when we believe a service provider would add value to the client and/or when a client requests such a referral. We have no compensation arrangement in place with these third parties. We at times provide relatively small gifts to the individual or entity as a sign of appreciation (such as a meal, gift certificate or a bottle of wine) for an introduction made to us. We typically entertain or are entertained by these third parties as a natural extension of our ongoing business relationship. Any level of entertainment we provide or receive is designed to foster our broader relationship with the individual or entity, and not to compensate others for entrusting us with referrals made. We want to make you aware of the inherent conflict of interest that exists from our relationship with these individuals or entities, as these introductions are generally borne out of a larger relationship. The Funds pay fees to broker-dealers and other financial intermediaries that provide distribution services for the Funds, as disclosed in the Funds’ offering documents. Altair employees are compensated by the firm based on new business attributed to the employee’s efforts. Clients do not pay additional fees to compensate the Altair employee for his/her new business efforts; rather, this compensation is addressed through Altair’s general operating budget. All professionals (including investment and research professionals) are paid a base salary and a bonus based on firm profitability. Senior Client Service team members are eligible to earn an additional one-time bonus based on the size of new client assets reflecting their role in securing a new client relationship. All employees are eligible to receive a bonus for an introduction to a client, which is calculated as a percentage of the first year of fees generated. Research employees are paid a bonus based on the long-term performance of funds and managers used by Altair clients. These compensation arrangements incent our employees to increase our assets under management which thereby increases our revenue generated. We feel our policies and procedures designed to ensure all clients are treated fairly as summarized within this disclosure brochure help to mitigate this inherent conflict. Also, all client portfolios are managed following a team approach, with no one employee responsible for any individual client’s portfolio. 14  ITEM 15 – CUSTODY Clients receive statements at least semi-annually from the broker dealer, bank or other qualified custodian that holds and maintains each client’s investment assets. Altair urges clients to carefully review and compare these custodial records and statements to the reports that we provide. Our reports will at times vary from custodial statements based on accounting procedures, reporting dates, trade/settlement dates or valuation methodologies of certain securities. Altair deducts advisory fees directly from clients’ accounts held at custodians and maintains constructive custody over some accounts of its clients since it can access their custodial accounts (either directly or indirectly via a third-party vendor) to perform services requested by the clients. Subject to approval by Altair’s Board of Managers and Compliance Committee, Altair also permits employees to serve as a trustee or similar role over certain client accounts. Finally, Altair has access to some clients’ third-party accounts. These arrangements result in Altair having custody over those accounts. Altair maintains strict controls for any account over which it believes it has custody, including limiting access to those individuals who are required to have such access to perform their jobs, active oversight by Altair management and engagement of an independent accountant to perform routine audits of the accounts. Altair owners will serve as trustee over other Altair owner’s personal accounts. Some of these Altair owners’ accounts are managed by Altair. The Funds’ assets are maintained with a qualified custodian, as disclosed in each Fund’s prospectus. ITEM 16 – INVESTMENT DISCRETION At the inception of the client engagement, Altair documents its discretionary authority in a written engagement contract for those clients who choose to give Altair investment discretion. Altair is directly responsible for making investment decisions on behalf of discretionary clients following an overall strategy documented in a written Investment Policy Statement, signed by the client, that includes investment guidelines and restrictions. In all cases, however, such discretion is exercised in a manner consistent with the stated investment objectives for the particular client account. ITEM 17 – VOTING CLIENT SECURITIES Altair does not vote proxies for securities on behalf of our clients, but third-party investment managers will vote proxies for client accounts as agreed upon between the third-party investment manager and client. With respect to the Funds, each Sub-Adviser is authorized to vote proxies for securities on behalf of the Funds, subject to the Funds’ proxy voting policies. ITEM 18 – FINANCIAL INFORMATION Altair has no known financial commitment that impairs its ability to meet contractual and fiduciary commitments to clients, and has not been the subject of a bankruptcy proceeding. 15  ITEM 19 – OTHER INFORMATION DUAL ROLES Altair’s Chief Compliance Officer, Rebekah Kohmescher, also serves as Altair’s Chief Executive Officer. Her other firm responsibilities will at times create an inherent conflict with Ms. Kohmescher’s compliance responsibilities. Altair management is aware of such inherent conflicts, and strives to maintain a strong compliance culture combined with appropriate processes and controls designed to ensure Ms. Kohmescher’s firm responsibilities do not impact her obligations as Altair’s Chief Compliance Officer. LEGAL LITIGATION Altair periodically receives notifications of pending class action or similar legal litigation involving securities held within client accounts. As a matter of policy, we do not elect to participate in such lawsuits or other settlements on behalf of our clients; rather, we provide an option for the client to utilize a third party (Chicago Clearing Corporation) to investigate and make elections on the clients’ behalf. The client makes a determination of whether to utilize Chicago Clearing Corporation within Altair’s engagement letter, which discloses that Chicago Clearing Corporation keep a percentage of the recovered proceeds as compensation. Altair is not responsible for class action or similar legal litigation matters related to the Funds. DISASTER RECOVERY Altair maintains a Disaster Recovery Plan designed to reasonably ensure the essential business functions of Altair are promptly restored in the event of a disaster event. While Altair strives to establish and maintain comprehensive processes supporting this Disaster Recovery Plan, Altair cannot ensure it will be able to continue business operations during every disaster event, given the unknown nature and scope of future events. Such events could include acts of war, terrorism, accidents and sabotage. If there were to be an actual disaster event, Altair will make reasonable attempts to notify clients of the impact of the event on Altair and its clients. CYBERSECURITY Information security concerns impact every user of the internet, and investment advisers such as Altair are no exception. Altair recognizes the importance of protecting clients' personal information as well as the confidential and proprietary information of Altair and its employees, and has established a Cybersecurity Program designed to protect this information. The Cybersecurity Program incorporates routine employee education, identification and monitoring of information security risks, the use of third-party vendors to combat such risks and an established Incident Response Plan. While Altair employs resources (both internal and external) it deems reasonable relative to its size and complexity to protect this information, Altair cannot guarantee the protection of all such information, nor can Altair assure against all related losses, in consideration of the real and evolving cybersecurity risks in existence (now or in the future). Altair believes clearly communicated information represents a critical control to identifying and managing cybersecurity risks, and has encouraged employees to communicate early and often regarding any potential cybersecurity risk. As such, Altair encourages all clients to communicate any information security risk or breach they have detected to their Altair consultant immediately. IDENTITY THEFT Altair recognizes the inherent risk all individuals face with respect to identity theft. Altair has created an Identity Theft Identification Program, primarily designed to help employees identify potential red flags indicating a client’s identity may have been stolen. In addition to identifying potential red flags, this Identity Theft Identification Program outlines the actions employees and Altair will take in the event they believe a client’s identity may have been stolen. Altair requests 16  any client who suspects his/her identity has been compromised to immediately notify their Altair consultant, thereby permitting Altair to consider implementing additional controls around the client’s account. DIMINISHED CAPACITY We are mindful that cognitive capacities can diminish over time, though not always as a result of age. We take our fiduciary responsibilities to our clients seriously, and have implemented policies to help guide our employees when they suspect a client is experiencing diminished capacity, as these clients could through no fault of their own be susceptible to making decisions which are not in their long-term best interests. As generally requested by the custodian, we encourage all clients to name a trusted contact with whom we could speak if we identify a potential diminished capacity concern. 17  Brochure Supplement Part 2B of Form ADV Steven B.
