The firm is principally controlled by Joseph Taiber, and Phillip Kosmala. Overview TAIKO provides investment and operational platform services (“Program”) to registered investment advisers (“Advisers”) and their clients. TAIKO builds custom Programs for advisers in which they direct the assets of their clients be allocated in various model portfolios created by TAIKO or third-party managers appointed by TAIKO based upon a rigorous due diligence process. In addition, TAIKO, as part of its Program service, provides operational and administrative services and otherwise assists and supports the Advisers’ business operations. Such assistance may involve marketing and business development, technology support, billing and administrative support, performance reporting and the provision of analytical tools, together with a collaborative environment of advisors to share ideas and best practices. 2  Please see Item 8 for a description of the firm’s investment process, including the methods of analysis, investment strategies, and the types of securities utilized in the provision of its services. As part of its service offering TAIKO will provide flash reports on significant market events, weekly communication concerning market highlights, as well as monthly capital markets commentary and more in-depth capital market highlights. Research TAIKO will provide investment vehicle due diligence and comprehensive research and strategy reports. In addition, the firm will provide recommended strategic asset/style allocations and investment strategies together with recommendations on rebalancing and manager changes. Please see Item 8 for additional information on methods of analysis and investment strategies. Identification, Selection and Ongoing Monitoring of Third-Party Managers Under the Program, TAIKO, third-party investment managers and / or other separate account managers appointed by TAIKO, (collectively, the “Managers”) provide access to managed accounts and model portfolios (the “Portfolios”), the Advisers determine which Portfolios the Client assets are to be invested in, and thereafter TAIKO implements all trades or trade instructions necessary to cause such assets to be invested in the Portfolios. In its discretion, Adviser will from time-to-time direct that assets of its clients (the “Assets”) be allocated into, and invested in, one or more of the Portfolios. Adviser will be solely responsible to designating which Clients will participate in Portfolios made available through the Program and the amount of client assets to be allocated to one or more portfolios. A client shall be deemed accepted by TAIKO to participate in the Program upon TAIKO’s acceptance of all necessary data and instructions with respect to that client provided by Adviser and delivered through the electronic portal or other electronic medium that is made available to Advisers by TAIKO and a part of the Program (the “Portal”). TAIKO will establish an account for each client with Program assets. TAIKO, in its discretion, may impose requirements and conditions on the opening and on-going maintenance of an account that participates in the Program. Adviser, subject to any restrictions imposed on the Adviser by the client, will, at all times, be solely responsible for determining and then monitoring whether any assets are invested in any portfolio, and if so, that amount of assets to be allocated among one or more portfolios, both initially and throughout the participation in the Program. Unless otherwise reserved to a client under the investment advisory agreement between Adviser and client (the “client agreement”), Adviser will all times retain discretion to determine how Assets are allocated among the portfolios. If reserved to a client, the client will decide how such client’s assets will be allocated among the portfolios. In all cases, Adviser is responsible for communicating to TAIKO how assets are to be allocated among the portfolios. All clients will be considered clients of Adviser and not of TAIKO, and therefore Adviser will have the primary contact with clients on an on-going basis. In all cases, the Advisor will be considered a client of TAIKO. Adviser shall be solely responsible for informing and advising each client on the allocation of their assets, the investment vehicles utilized by a portfolio in which 3  that client’s assets are allocated (including their objectives). Adviser or the client (as provided in the client agreement) will be solely responsible for designating a custodian for each Account, and the client agreement must authorize TAIKO and the managers to direct trades for clients’ accounts at the custodian. Manager Selection At its own expense, TAIKO in its sole discretion will have the right to engage and terminate any third-party portfolio managers to create and manage any portfolios. TAIKO will provide Adviser a schedule of managers who have agreed to participate in the Program, and periodically shall update such schedule. The schedule, which describes the investment objectives and styles of each manager or model and other relevant investment criteria, will be included in Program materials provided to Adviser. Portfolio Composition TAIKO, or managers selected by TAIKO, will retain complete discretion to formulate, monitor, and revise the portfolios. TAIKO will perform due diligence on recommended product offerings and recommend strategic asset/style allocations and investment strategies in each portfolio. Operations Platform New Accounts TAIKO will provide its Adviser clients with the following operational support: • Managed account set-up • Maintenance order processing • Interface with money managers and custodian to process account maintenance requests including manager changes, rebalancing, tax selling, terminations, distributions, adding/removing restrictions, address changes, DTC transfers, gifting and account-level fee changes • Error identification and resolution • Dedicated relationship manager - sales and products • Dedicated account manager - service and operations initiatives • Dedicated service representative - day-to-day operational support • Home office training - technology, new account and maintenance process, BD operations activities Billing and Payment • Portfolio inception billing • Quarterly billing in arrears, unless otherwise accommodated. • Unbundled or total fee structure • Debit the accounts and remit advisor, third party manager, and TAIKO payments 4  Trade Reconciliation • Daily reconciliation of portfolio with portfolio accounting system and custodian to ensure our reporting is accurate and timely. Trading Subject to Adviser electing to cause a client’s assets to be a part of the Program and allocated into one or more portfolios, TAIKO, or any manager, has the sole discretion and responsibility for implementing instructions provided to TAIKO by Adviser respecting the allocation of assets among portfolios. By electing to allocate client assets to a portfolio, subject to any restrictions communicated to TAIKO, Adviser is granting TAIKO discretionary authority to make all investment decisions consistent with its direction and this Agreement with respect to the accounts—but in all cases TAIKO’s discretion is limited to implementing transactions necessary to allocate assets among portfolios as directed by Adviser. Such discretionary authority allows TAIKO, when TAIKO deems appropriate and without prior consultation with the Adviser or client, to buy, sell, exchange, convert and otherwise trade in any security or otherwise deal with portfolio assets in its discretion and to delegate such investment discretion to managers—but in all cases TAIKO’s discretion is limited to implementing transactions necessary to allocate assets among portfolios as directed by Adviser. TAIKO or any manager, as applicable, will direct the custodians to effect transactions for the accounts so that assets are invested into and among portfolios, including the implementation of portfolio changes from time to time in their discretion. Portfolio Transaction For any client assets that Adviser has directed be a part of the Program and allocated into one or more portfolios, TAIKO shall be solely responsible for, and shall have full discretion to, place trades for the accounts in the portfolios. TAIKO will not be liable to clients, Adviser or any manager for any act, conduct, error or omission of custodian or any third-party broker or dealer. Performance Reporting & Portal Communications TAIKO will provide an electronic portal through which it will upload performance reports for secure access by its Adviser clients. The portal will allow Advisers to retrieve quarterly performance reports, on-demand reports, manager support and communications, access to managers’ ADV Part 2. Administrative Services In addition to making the portfolios available to Adviser, TAIKO will provide to Adviser those support and administrative services identified below: Software TAIKO’s services may include access to and/or use of third-party software by Adviser or indirectly by Adviser’s participation in the Program. Use of such software is subject to the terms and conditions of the software provider. Online Services Certain deliverables and services that are included in the Program will be provided online through the portal, including: (i) deliverables associated with the Program that are delivered electronically; 5  and (ii) services provided electronically, including hosting services and software provided electronically. The terms and conditions governing the use of the services provided electronically are posted on TAIKO’s website. Marketing Services TAIKO will provide assistance to the Advisers in helping create a brand presence, welcome kit, develop investment proposals, website creation and hosting together with content updates, creation of co-branded marketing materials, newsletter creation, database and event marketing, and related marketing administrative support services. In addition, the firm may provide sales force training and education. In addition, the firm as mutually agreed upon by the Adviser and TAIKO, may provide assistance related to event promotion, event coaching, digital marketing, preparation and distribution of social media blog posts, podcasts and related marketing support. In an effort to show our commitment to our Advisers TAIKO will provide: • Advisor-level support • Dedicated business development representative and regional director • Systems training (e.g., proposal system, workstations) • Business development, sales, marketing support Client Assets Under Management As of March 25, 2025, TAIKO had $1,951,056,672 in discretionary and $2,295,377,172 of non- discretionary regulatory assets under management for total assets of $4,246,43,844. Item 5. Fees and Compensation TAIKO Services For the services contemplated in Item 4 of this brochure TAIKO charges an asset-based fee that ranges from 0.20%-1.2% dependent upon several factors including average account size, number of accounts, fee structures of third-party model providers, if applicable, and whether TAIKO is providing its proprietary model portfolios to the Adviser. Fees will be calculated at the negotiated rate and will be billed in arrears. General Information on Fees In certain circumstances, all fees and account minimums may be negotiable. The fee charged is calculated as described above and is not charged on the basis of a share of capital gains upon or capital appreciation of the funds or any portion of the funds of an advisory client (SEC Rule 205(a)(l)). In addition to TAIKO’s fees, Clients will be responsible for trading costs, custodian fees, transfer taxes, SEC fees and related fees. TAIKO pays third-party managers, if appointed by TAIKO, from its portion of the aggregate advisory fee which it bills to clients quarterly in arrears. Clients may terminate any client agreement any time as provided therein or otherwise terminate that client’s participation in the Program. Unless otherwise agreed, the termination of a client’s participation in the Program shall be communicated to TAIKO by Adviser within ten days and will be affected by the termination by the custodian of the data feed and information that is specific to that client. Any such termination will terminate any further obligations of the parties hereunder with 6  respect to the Account of the applicable client, except for obligations incurred prior to the termination or as may otherwise be provided in a client agreement respecting Adviser’s obligations thereunder. Upon termination of a client agreement or termination by a client of client’s participation in the Program, Adviser will cooperate to affect the Client’s directives respecting such termination. Adviser may terminate this Agreement: (i) by providing TAIKO 60 days written notice of its intent to terminate; or (ii) immediately if TAIKO is in breach of the representations, warranties and covenants set forth in Section 10(b)(ii) or Section 10(b)(v) of this Agreement. If upon termination of this Agreement by the Adviser any Client elects or requests to have any of its Assets remain in the Program, TAIKO may recommend a separate third-party investment adviser to that Client to serve as the investment adviser for that Client. TAIKO may terminate this Agreement: (i) if the aggregate market value of all Accounts of Clients of the Adviser that participate in the Program at any time is below the Account minimum identified on Exhibit F (the “Aggregate Minimum”) by providing Adviser 90 days written notice of TAIKO’ intent to terminate; or (ii) immediately if Adviser is in breach of the representations, warranties and covenants set forth in Section 10(a)(ii) or Section 10(a)(vi) of this Agreement. The Aggregate Minimum may be updated from time to time by TAIKO, and TAIKO shall use reasonable efforts to communicate any updates to the Aggregate Minimum to Adviser. TAIKO must provide its services hereunder at the same level, quality and timeliness until termination of this Agreement as prior to its receipt or delivery of notice of termination. TAIKO shall use its best efforts to provide Adviser at least 14 days’ advance notice prior to terminating any third-party manager. Adviser must then assess whether the change in the Manager and/or Portfolios will negatively impact any Accounts, and if so, direct TAIKO to re-allocate such Assets. TAIKO shall not be liable to a Client for any losses, decreases in value, or adverse tax consequences that may result from the termination of a Manager, the appointment of a new Manager and any resulting transactions effected to changes in the composition of any Portfolio. All fees paid to TAIKO for investment advisory services are separate and distinct from the fees and expenses charged by mutual funds to their shareholders. These fees and expenses are described in each fund's prospectus. These fees will generally include a management fee, other fund expenses, and a marketing/distribution fee. A client could invest in a mutual fund directly, without the services of TAIKO. In that case, the client would not receive the services provided by TAIKO which are designed, among other things, to assist the client in determining which mutual fund or funds are most appropriate to each client’s financial condition and objectives. TAIKO’s advisory professionals are compensated primarily through a salary and bonus structure. TAIKO’s advisory professionals may receive commission-based compensation for the sale of insurance products. Please see Item 10 for detailed information and conflicts of interest. Item 6. Performance-Based Fees and Side-by-Side Management TAIKO does not charge any performance-based fees to clients. Item 7. Types of Clients TAIKO primarily provides customized investment management services to registered investment advisers and their clients, which may be individuals and associated trusts, foundations, endowments, banks or thrift institutions, pension and profit-sharing plans, and other corporations or business entities not otherwise considered institutional clients. TAIKO considers portfolios of an aggregate 7  value of less than $5,000,000 to be non-institutional. A minimum aggregate portfolio size of $25,000; however, in certain circumstances the minimum portfolio size may be negotiable. Item 8. Methods of Analysis, Investment Strategies and Risk of Loss The objective of our asset allocation theory and models is to assist clients in achieving superior returns given their risk tolerance level. The combination of proprietary research, academic theory and market research helps to guide our asset allocation decisions. TAIKO may also utilize a variety of computer- simulated models in proposing asset allocations for clients. TAIKO’s manager research efforts often blend quantitative screens with an emphasis on our senior professional’s product knowledge and the dynamic interaction between investment process and investment cycles. TAIKO’s due diligence of third-party managers typically includes, but is not limited to, the following: • Assets under management and growth in assets under management • Ownership structure • Investment thesis repeatability of investment process • Industry reputation • Depth of research staff • Market cap analysis • Portfolio duration and structure analysis • Expenses • Turnover & trading costs • Composite construction methodology TAIKO may use third-party databases such as Zephyr, Morningstar, Investment Metrics, and eVestment Alliance as primary tools for initial screening, quantitative, and comparative research of third-party mutual funds, exchange-traded funds, and managers. TAIKO utilizes databases of various managers, and regularly reviews the portfolio performance and holdings of recommended managers in comparison to their peers. Risk of Loss All investing involves a risk of loss that clients should be prepared to bear. The identification of securities and other assets believed to be undervalued is a difficult task, and there are no assurances that such opportunities will be successfully recognized or acquired by third-party managers. TAIKO cannot give any guarantee that it will achieve a client’s investment objectives or that clients will receive a return of its investment. Below is a summary of potentially material risks for each significant TAIKO investment strategy used, the methods of analysis used, and/or the particular type of security recommended. Lack of Control – TAIKO will not have a role in the management of clients’ third- party managed accounts and it will likely not have the opportunity to evaluate in advance the specific investments made by any third-party managers. As a result, the rates of return to clients will primarily depend upon investment and management decisions of third-party managers and returns could be adversely 8  affected by the unfavorable performance of such managers. Item 9. Disciplinary Information TAIKO and its employees have not been involved in any legal or disciplinary events in the past 10 years that would be material to a client’s evaluation of the company or its personnel. Item 10. Other Financial Industry Activities and Affiliations As mentioned earlier, TAIKO provides its consulting services to numerous types of clients which may include financial organizations. To mitigate actual and potential conflicts of interest, TAIKO will disallow any investment firm that purchases services from any employee from participating in any recommended list of investment firms prepared on behalf of TAIKO's clients. It is TAIKO's policy that no employee or any member of the employee's immediate family may sell any product or service to any investment firms that currently manage assets on behalf of TAIKO's clients. TAIKO is partially controlled by Phil Kosmala and Joe Taiber, who jointly own Taiber Kosmala & Associates, LLC, an SEC-registered investment adviser headquartered in Chicago IL. Item 11. Code of Ethics, Participation or Interest in Client Transactions and Personal Trading Participation or Interest in Client Transactions TAIKO has established the following restrictions in order to ensure its fiduciary responsibilities: 1) No member or employee of TAIKO shall buy or sell securities for their personal portfolio(s) where their decision is substantially derived, in whole or in part, by reason of his or her employment unless the information is also available to the investing public on reasonable inquiry. No person of TAIKO shall prefer his or her own interest to that of the advisory client. 2) TAIKO maintains a list of all securities holdings for itself, and anyone associated with its advice my practice with access to advisory recommendations. 3) TAIKO emphasizes the unrestricted right of the client to decline to implement any advice rendered by TAIKO. 4) TAIKO emphasizes the unrestricted right of the client to select and choose any broker or dealer he or she wishes. 5) TAIKO requires that all individuals must act in accordance with all applicable Federal and State regulations governing registered investment advisory practices. Code of Ethics TAIKO's Code of Ethics (the "Code") governs the business and employees of TAIKO. The Code provides principles and rules to be followed by members, officers and employees of TAIKO in the performance of their professional duties. The Code operates in conjunction with TAIKO's policies and procedures that govern employees. The basic principle that governs the conduct of the applicant's business is loyalty to the interests of 9  its clients. The Code provides that no TAIKO officer or employee, directly or indirectly, shall (a) employ any device, scheme or artifice to defraud a client; (b) engage in any act, practice or course of conduct which operates or would operate as a fraud to deceit upon a client; or (c) engage in any manipulative practice with respect to a client. The Code requires that no officer or employee profit, directly or indirectly from his or her position with TAIKO to the detriment or at the expense of clients; and no officer or employee of TAIKO shall take for his or her own advantage any corporate opportunity for profit, which he or she learns about due to such person's position with TAIKO. TAIKO's Code, among other things, prohibits officers and employees of TAIKO from engaging in securities purchase and sale transactions while in possession of material non-public information or in a transaction that is known to be opposite TAIKO clients, to be a misuse of non-public or TAIKO information regarding clients, portfolios and securities and making, soliciting and accepting (other than as a family member) gifts of more than modest value, preferential treatment or other considerations. Conflicts of interest must be disclosed to TAIKO's Chief Compliance Officer, who is responsible for enforcing the Code. TAIKO's Code also requires employees to: 1) pre-clear certain personal securities transactions, 2) report personal securities transactions on at least a quarterly basis, and 3) provide TAIKO with a detailed summary of certain holdings (both initially upon commencement of employment and annually thereafter) over which such employees have a direct or indirect beneficial interest. A copy of the Code will be provided to any client or perspective client upon request. TAIKO's current Chief Compliance Officer is Phillip Kosmala. Mr. Kosmala is also engaged in providing advisory services to TAIKO clients and his background and experience is summarized in Form 2B. Item 12. Brokerage Practices Custodian Recommendations TAIKO considers the financial strength, reputation, operational efficiency, cost, execution capability, level of customer service, and related factors in recommending broker-dealers or custodians to advisory clients. In certain instances, and subject to approval by TAIKO, TAIKO will recommend to clients certain other broker-dealers and/or custodians based on the needs of the individual client, and taking into consideration the nature of the services required, the experience of the broker-dealer or custodian, the cost and quality of the services, and the reputation of the broker-dealer or custodian. The final determination to engage a broker-dealer or custodian recommended by TAIKO will be made by and in the sole discretion of the client. The client recognizes that broker-dealers and/or custodians have different cost and fee structures and trade execution capabilities. As a result, there may be disparities with respect to the cost of services and/or the transaction prices for securities transactions executed on behalf of the client. Clients are responsible for assessing the commissions and other costs charged by broker-dealers and/or custodians. How We Select Brokers/Custodians to Recommend TAIKO seeks to recommend a custodian/broker who will hold client assets and execute transactions on terms that are overall most advantageous when compared to other available providers and their services. We consider a wide range of factors, including, among others, the following: • combination of transaction execution services along with asset custody services 10  (generally without a separate fee for custody) • capability to execute, clear, and settle trades (buy and sell securities for client accounts) • capabilities to facilitate transfers and payments to and from accounts (wire transfers, check requests, bill payment, etc.) • breadth of investment products made available (stocks, bonds, mutual funds, exchange- traded funds (ETFs), etc.) • availability of investment research and tools that assist us in making investment decisions • quality of services • competitiveness of the price of those services (commission rates, margin interest rates, other fees, etc.) and willingness to negotiate them reputation, financial strength, and stability of the provider their prior service to us and our other clients • • • availability of other products and services that benefit us, as discussed below Soft Dollar Arrangements As a result of the firm’s recommendation to clients to custody assets with a specific custodian, the firm is deemed to be in receipt of soft dollar benefits from said custodian. Please refer to the following for disclosure of such benefits. Institutional Trading and Custody Services The custodian provides TAIKO with access to its institutional trading and custody services, which are typically not available to the custodian’s retail investors. These services generally are available to independent investment advisors on an unsolicited basis, at no charge to them so long as a certain minimum amount of the advisor’s clients’ assets are maintained in accounts at a particular custodian. The custodian’s brokerage services include the execution of securities transactions, custody, research, and access to mutual funds and other investments that are otherwise generally available only to institutional investors or would require a significantly higher minimum initial investment. Other Products and Services Custodian also makes available to TAIKO other products and services that benefit TAIKO but may not directly benefit its clients’ accounts. Many of these products and services may be used to service all or some substantial number of TAIKO's accounts, including accounts not maintained at custodian. The custodian may also make available to TAIKO software and other technology that • provide access to client account data (such as trade confirmations and account • statements) facilitate trade execution and allocate aggregated trade orders for multiple client accounts facilitate payment of TAIKO’s fees from its clients’ accounts • provide research, pricing and other market data • • assist with back-office functions, recordkeeping and client reporting The custodian may also offer other services intended to help TAIKO manage and further develop its business enterprise. These services may include 11  • compliance, legal and business consulting • publications and conferences on practice management and business succession • access to employee benefits providers, human capital consultants and insurance providers The custodian may also provide other benefits such as educational events or occasional business entertainment of TAIKO personnel. In evaluating whether to recommend that clients custody their assets at the custodian, TAIKO may take into account the availability of some of the foregoing products and services and other arrangements as part of the total mix of factors it considers, and not solely the nature, cost or quality of custody and brokerage services provided by the custodian, which may create a potential conflict of interest. Independent Third Parties The custodian may make available, arrange, and/or pay third-party vendors for the types of services rendered to TAIKO. The custodian may discount or waive fees it would otherwise charge for some of these services or all or a part of the fees of a third party providing these services to TAIKO. Additional Compensation Received from Custodians TAIKO may participate in institutional customer programs sponsored by broker-dealers or custodians. TAIKO may recommend these broker-dealers or custodians to clients for custody and brokerage services. There is no direct link between TAIKO’s participation in such programs and the investment advice it gives to its clients, although TAIKO receives economic benefits through its participation in the programs that are typically not available to retail investors. These benefits may include the following products and services (provided without cost or at a discount): • Receipt of duplicate client statements and confirmations • Research-related products and tools • Consulting services • Access to a trading desk serving TAIKO participants • Access to block trading (which provides the ability to aggregate securities transactions for execution and then allocate the appropriate shares to client accounts) • The ability to have advisory fees deducted directly from client accounts • Access to an electronic communications network for client order entry and account information • Access to mutual funds with no transaction fees and to certain institutional money managers • Discounts on compliance, marketing, research, technology, and practice management products or services provided to TAIKO by third-party vendors The custodian may also pay for business consulting and professional services received by TAIKO’s related persons and may pay or reimburse expenses (including client transition expenses, travel, lodging, meals and entertainment expenses for TAIKO’s personnel to attend conferences). Some of the products and services made available by such custodian through its institutional customer programs may benefit TAIKO but may not benefit its client accounts. These products or services may assist TAIKO in managing and administering client accounts, including accounts not maintained at the custodian as applicable. Other services made available through the programs are intended to help TAIKO manage and further develop its business enterprise. The benefits received by TAIKO or its 12  personnel through participation in these programs do not depend on the amount of brokerage transactions directed to the broker-dealer. TAIKO also participates in similar institutional advisor programs offered by other independent broker-dealers or trust companies, and its continued participation may require TAIKO to maintain a predetermined level of assets at such firms. In connection with its participation in such programs, TAIKO will typically receive benefits similar to those listed above, including research, payments for business consulting and professional services received by TAIKO’s related persons, and reimbursement of expenses (including travel, lodging, meals and entertainment expenses for TAIKO’s personnel to attend conferences sponsored by the broker-dealer or trust company). As part of its fiduciary duties to clients, TAIKO endeavors at all times to put the interests of its clients first. Clients should be aware, however, that the receipt of economic benefits by TAIKO or its related persons in and of itself creates a potential conflict of interest and may indirectly influence TAIKO’s recommendation of broker-dealers for custody and brokerage services. Item 13. Review of Accounts TAIKO conducts reviews of (i) the model portfolios it manages, (ii) third-party managers it appoints on behalf of its adviser firm clients and their respective clients. Such reviews will be done on an ongoing basis but no less frequently than quarterly. More frequent reviews may also be triggered by a change in the client’s investment objectives, tax considerations, large deposits or withdrawals, large purchases or sales, loss of confidence in corporate management, or changes in macro- economic climate. All accounts are reviewed by TAIKO's investment committee. TAIKO may perform ad hoc reviews on an as-needed basis if there have been material changes in the client’s investment objectives or risk tolerance, or a material change in how TAIKO formulates investment advice. Clients should review the disclosure documents of recommended managers for information on the managers’ account review practices. Ongoing Performance Evaluation, Reports on Managers, and Investment Supervisory Services: TAIKO will provide clients with a quarterly report of manager performance. Clients should review the disclosure documents of recommended managers for information on reports provided by the managers to clients. TAIKO generally reports the value of client's investment portfolios to the client on a quarterly basis. The value of a client's investment portfolio also may be the basis of management fees to TAIKO. TAIKO does not itself value the securities in a client's account. Rather, TAIKO relies upon values provided by the custodian, fund manager, fund auditor, and/or fund administrator. TAIKO understands that securities listed on exchanges are valued at their closing price as the last trading day of the calendar quarter as reported by the custodian or pricing service. The value of specified illiquid, foreign or private investments for which valuation information is not available through a custodian or an independent pricing service is generally provided by the fund's auditor, administrator, or the fund manager. In the event that TAIKO must internally “fair value” an investment, the Company will use its best efforts and all appropriate means to obtain all relevant information in order to determine a fair value. If it is deemed necessary or prudent, TAIKO may hire an independent third party to provide an appraisal of the investment. The client’s independent custodian provides account statements directly to the client no less 13  frequently than quarterly. The custodian’s statement is the official record of the client’s securities account and supersedes any statements or reports created on behalf of the client by TAIKO. Item 14. Client Referrals and Other Compensation Please refer to the disclosures in Items 10 and 12 regarding referrals to third-party service providers and benefits the firm receives from its custodian(s). TAIKO may receive economic benefits for referring clients to third-party service providers. You are under no obligation to utilize any service provider recommended to you by TAIKO or its affiliates. Item 15. Custody All clients' accounts are held in custody by unaffiliated qualified custodian, but the Company can access certain clients' funds though our ability to debit advisory fees. In these cases, TAIKO is considered to have custody of client assets under Rule 206(4)-2 under the Advisers Act. Account custodians send statements directly to the account owners on at least a quarterly basis. TAIKO urges clients to carefully review these statements and compare the statements to any account statements provided by TAIKO. As a practical matter, neither TAIKO nor any manager will have possession or custody of cash and/or securities in any accounts or any responsibility or liability for custody, which will remain solely with custodian. Item 16. Investment Discretion TAIKO’s discretion is limited to implementing transactions necessary to allocate Assets among Portfolios as directed by Adviser. Such discretionary authority allows TAIKO, when TAIKO deems appropriate and without prior consultation with the Adviser or Client, to buy, sell, exchange, convert, and otherwise trade in any security or otherwise deal with Portfolio assets in its discretion and to delegate such investment discretion to Managers—but in all cases TAIKO’s discretion is limited to implementing transactions necessary to allocate Assets among Portfolios as directed by Adviser. TAIKO or any Manager, as applicable, will direct the Custodians to effect transactions for the Accounts so that Assets are invested into and among Portfolios, including the implementation of Portfolio changes from time to time in their discretion. Item 17. Voting Client Securities TAIKO does not vote or provide guidance regarding the voting of proxies. In some instances, certain direct indexing strategy managers may vote proxies, but in all other cases Clients are responsible for voting proxies. Clients should contact their custodian with questions about receiving proxies and process for the client to execute voting on such proxies. Item 18. Financial Information TAIKO has never filed for bankruptcy and is not aware of any financial condition that is expected to affect its ability to manage client accounts. 14  Part 2B of Form ADV The Brochure Supplement 141 W.
