Types of Advisory Services Portfolio Management PWA’s portfolio management service is designed to assist clients in meeting their financial goals through the use of financial investments. For each portfolio management client, PWA will conduct one or more meetings (in person if possible, otherwise via telephone conference) with the client in order to understand the client’s current financial situation, existing resources, financial goals, and tolerance for risk. Based on the foregoing, PWA will propose an investment approach to the client. PWA may propose an investment portfolio, consisting of exchange traded funds, mutual funds, individual stocks or bonds, or other securities. Upon the client’s agreement to the proposed investment plan, PWA will work with the client to establish or transfer investment accounts so that PWA is able to manage the client’s portfolio. Once the relevant accounts are under PWA’s management, PWA will review such accounts on a regular basis and at least quarterly. PWA may periodically rebalance or adjust client accounts under its management. If the client experiences any significant changes to his/her financial or personal circumstances, the client must notify PWA so that PWA can consider such information in managing the client’s investments. Financial Planning/Financial Consulting PWA offers financial planning and financial consulting services to individuals, families, business organizations, and other clients. These services will be provided pursuant to a written client agreement. PWA can work with a client to develop a written financial plan or provide consulting services on specific issues or areas that are of concern to the client. The goal of a financial planning engagement is to provide the client with a written financial plan that will assist the client in meeting his/her financial goals. PWA and the client will discuss and agree upon the specific topics to be covered by the financial plan. Such topics may include investment planning, retirement planning, tax planning, insurance planning, estate planning, or business planning. PWA will conduct one or more meetings (in person if possible, otherwise via telephone conference) with the client in order to understand the client’s current financial situation, financial goals, specific issues or questions, and topics to be covered by the financial plan. PWA may also request copies of relevant financial documents, such as account statements, income tax returns, insurance policies, retirement plans, estate planning documents, and business financial statements. PWA will then prepare a written financial plan that summarizes the client’s current financial situation and offers observations and recommendations. PWA prepares the financial plan based on the information provided to PWA by the client and as of the date that the plan is submitted to the client. PWA undertakes no responsibility to update the financial plan unless PWA and the client agree upon a subsequent financial planning engagement or the client agrees to PWA’s monthly retainer fee, in which case the client will have responsibility to furnish updated information as necessary. PWA also offers financial consulting services on specific issues or areas that are of concern to the client. PWA will obtain background information on the issues or topics to be covered by the financial consulting engagement through client meetings and documents provided by the client. PWA will then offer advice or recommendations to the client. Such advice or recommendations may or may not be in writing depending on the nature of the engagement. Pension Consulting Services Pension Consulting consists of assisting employer plan sponsors establish, monitor and review their company's participant‐directed retirement plan. As the needs of the plan sponsor dictate, areas of advising could include: investment options, plan structure, participant education. Miscellaneous Disclosures Non‐Investment Consulting/Implementation Services To the extent requested by the client, PWA may provide consulting services regarding non‐investment related matters, such as estate planning, tax planning, insurance, etc. Neither PWA, nor any of its representatives, serves as an attorney or accountant and no portion of PWA’s services should be construed as same. To the extent requested by a client, PWA may recommend the services of other professionals for certain non‐ investment implementation purposes (i.e., attorneys, accountants, insurance, etc.). The client is under no obligation to engage the services of any such recommended professional. The client retains absolute discretion over all such implementation decisions and is free to accept or reject any recommendation from PWA. Please Note: If the client engages any such recommended professional, and a dispute arises thereafter relative to such engagement, the client agrees to seek recourse exclusively from and against the engaged professional. Please Also Note: It remains the client’s responsibility to promptly notify PWA if there is ever any change in his/her/its financial situation or investment objectives for the purpose of reviewing/evaluating/revising PWA’s previous recommendations and/or services. Client Obligations In performing its services, PWA shall not be required to verify any information received from the client or from the client’s other professionals and is expressly authorized to rely thereon. Moreover, each client is advised that it remains his/her/its responsibility to promptly notify PWA if there is ever any change in his/her/its financial situation or investment objectives for the purpose of reviewing/evaluating/revising PWA’s previous recommendations and/or services. Limitations of Financial Planning and Non‐Investment Consulting/Implementation Services As indicated above, if, subsequent to completion of the initial planning and consulting services engagement, the client determines to engage PWA to provide investment advisory services per the terms and conditions of the above‐referenced Investment Advisory Agreement, PWA’s annual investment advisory fee thereafter shall generally include (with exceptions) ongoing financial planning and consulting services, to the extent specifically requested by the client. In the event that the client requires extraordinary planning and/or consultation services (to be determined in the sole discretion of PWA), PWA may determine to charge an additional fee for such services, the dollar amount of which shall be set forth in a separate written notice to the client. PWA believes that it is important for the client to address financial planning issues on an ongoing basis. PWA’s advisory fee, as set forth at Item 5 below, will remain the same regardless of whether or not the client determines to address financial planning issues with PWA PWA does not serve as an attorney, accountant, or insurance agent, and no portion of our services should be construed as same. Accordingly, PWA does not prepare legal documents, prepare tax returns, or sell insurance products. To the extent requested by a client, PWA may recommend the services of other professionals for non‐ investment implementation purpose (i.e., attorneys, accountants, insurance, etc.), including PWA’s Chief Operating Officer, for insurance

sales/services per a separate engagement and fee. The client is not under any obligation to engage any such professional(s). The client retains absolute discretion over all such implementation decisions and is free to accept or reject any recommendation from PWA and/or its representatives. If the client engages any unaffiliated professional (i.e., attorney, accountant, insurance agent, etc.) recommended or otherwise, and a dispute arises thereafter relative to such engagement, the client agrees to seek recourse exclusively from the engaged professional. At all times, the engaged unaffiliated licensed professional[s] (i.e., attorney, accountant, insurance agent, etc.), and not PWA, shall be responsible for the quality and competency of the services provided. Initial Planning and Consulting Services To the extent requested and separately engaged by the client to do so, PWA will generally provide initial financial planning and related consulting services regarding matters such as tax and estate planning, insurance, etc. per the terms and conditions of a separate agreement and a separate fee as discussed at Item 5 below. Prior to engaging PWA to provide initial planning or consulting services, clients are generally required to enter into a Financial Planning and Consulting Agreement with PWA setting forth the terms and conditions of the engagement (including termination), describing the scope of the services to be provided, and the portion of the fee that is due from the client prior to PWA commencing services. Cash Positions Registrant continues to treat cash as an asset class. As such, unless determined to the contrary by Registrant, all cash positions (money markets, etc.) shall continue to be included as part of assets under management for purposes of calculating Registrant’s advisory fee. At any specific point in time, depending upon perceived or anticipated market conditions/events (there being no guarantee that such anticipated market conditions/events will occur), Registrant may maintain cash positions for defensive purposes. In addition, while assets are maintained in cash, such amounts could miss market advances. Depending upon current yields, at any point in time, Registrant’s advisory fee could exceed the interest paid by the client’s money market fund. Please Note: Retirement Rollovers‐Potential for Conflict of Interest A client or prospective client leaving an employer typically has four options regarding an existing retirement plan (and may engage in a combination of these options): (i) leave the money in the former employer’s plan, if permitted, (ii) roll over the assets to the new employer’s plan, if one is available and rollovers are permitted, (iii) roll over to an Individual Retirement Account (“IRA”), or (iv) cash out the account value (which could, depending upon the client’s age, result in adverse tax consequences). If PWA recommends that a client roll over their retirement plan assets into an account to be managed by PWA, such a recommendation creates a conflict of interest if PWA will earn new (or increase its current) compensation as a result of the rollover. If PWA provides a recommendation as to whether a client should engage in a rollover or not (whether it is from an employer’s plan or an existing IRA), PWA is acting as a fiduciary 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. No client is under any obligation to roll over retirement plan assets to an account managed by PWA, whether it is from an employer’s plan or an existing IRA. PWA’s Chief Compliance Officer, Aaron J. Plautz remains available to address any questions that a client or prospective client may have regarding the potential for conflict of interest presented by such rollover recommendation. Custodian Charges ‐ Additional Fees As discussed below at Item 12 below, when requested to recommend a broker‐dealer/custodian for client accounts, PWA generally recommends that Schwab serve as the broker‐dealer/custodian for client investment management assets. Broker‐dealers such as Schwab charge brokerage commissions, transaction, and/or other type fees for effecting certain types of securities transactions (i.e., including transaction fees for certain mutual funds, and mark‐ups and mark‐downs charged for fixed income transactions, etc.). The types of securities for which transaction fees, commissions, and/or other type fees (as well as the amount of those fees) shall differ depending upon the broker‐dealer/custodian (while certain custodians, including Schwab, do not currently charge fees on individual equity transactions, others do. Please Note: there can be no assurance that Schwab will not change their transaction fee pricing in the future). These fees/charges are in addition to PWA’s investment advisory fee disclosed at Item 5 below. PWA does not receive any portion of these fees/charges. ANY QUESTIONS: PWA’s Chief Compliance Officer, Aaron J. Plautz remains available to address any questions that a client or prospective client may have regarding the above. Portfolio Activity PWA has a fiduciary duty to provide services consistent with the client’s best interest. PWA will review client portfolios on an ongoing basis to determine if any changes are necessary based upon various factors, including, but not limited to, investment performance, market conditions, fund manager tenure, style drift, account additions/withdrawals, and/or a change in the client’s investment objective. Based upon these factors, there may be extended periods of time when PWA determines that changes to a client’s portfolio are neither necessary, nor prudent. Clients remain subject to the fees described in Item 5 below during periods of account inactivity. Please Note: Use of Mutual and Exchange Traded Funds: PWA utilizes mutual funds and exchange traded funds for its client portfolios. In addition to PWA’s investment advisory fee described below, and transaction and/or custodial fees discussed below, clients will also incur, relative to all mutual fund and exchange traded fund purchases, charges imposed at the fund level (e.g., management fees and other fund expenses). Please Note: Investment Risk. Different types of investments involve varying degrees of risk, and it should not be assumed that future performance of any specific investment or investment strategy (including the investments and/or investment strategies recommended or undertaken by PWA) will be profitable or equal any specific performance level(s).
