A. Firm Information Columbia Asset Management (“CAM” or the “Advisor”) is registered investment advisor with the U.S. Securities and Exchange Commission (“SEC”). CAM was founded in 1997 by Brian H. Weisman and since that time has offered investment advisory and consulting services. At present, Mr. Weisman is our principal owner. The Disclosure Brochure provides information regarding the qualifications, business practice, and the advisory services provided by CAM B. Advisory Services Offered CAM offers investment advisory services to clients, who may be individuals, trusts, estates, corporations, and charitable organizations (each referred to as a “Client”). The Advisor serves as a fiduciary to Clients, as defined under the applicable laws and regulations. As a fiduciary, the Advisor upholds a duty of loyalty, fairness, and good faith towards each Client and seeks to mitigate any potential conflict of interest. CAM’s fiduciary commitment is further described in the Advisor’s Code of Ethics. For more information please see Item 11 – Code of Ethics, Participation or Interest in Client Transactions and Personal Trading. Wealth Management Services CAM provides customized wealth management solutions for its Clients. This achieved through continuous personal Client contacts and interaction while providing discretionary investment management and related financial planning services CAM works closely with each Client to identify their investment goals and objectives as well as risk tolerance and financial situation to create a portfolio strategy. CAM will then construct an investment portfolio using equities and fixed income including individual stocks, individual fixed income, mutual funds and exchange traded funds to achieve the Client’s investment goals. The Advisor may retain certain types of investments based on the Client’s legacy investments based on portfolio fit and/or tax considerations. CAM will select, recommend and/or retain securities (stocks, bonds, mutual funds & ETFs) on an individual holding’s basis. Investment decisions are made according to the investment objectives and risk tolerances of each client, and the client’s stated investment restrictions (if any) and special circumstances. CAM’s investment approach is primarily long-term focused, but the Advisor may buy, sell or re- allocate positions that have been held for less than one year to meet the objectives of the Client or due to market conditions. CAM will construct, implement, and monitor the portfolio to ensure the selection aligns with the Client’s financial objective. CAM evaluates and selects investments for inclusion in Client portfolios only after applying it internal due diligence. CAM may recommend redistributing investment allocations to diversify the portfolio. CAM may recommend specific positions to increase sector or asset class weightings. The Advisor may recommend employing/increasing cash positions as a hedge against market movement. CAM may recommend selling positions for reasons that include, but are not limited to, harvesting capital gains or losses, business or sector risk exposure to a specific security or class of securities, overevaluation or overweighting of the position[s] in the portfolio, change in risk tolerance of the Client, generating cash to meet Client needs, or any risk deemed unacceptable for the Client’s risk tolerance. At no time will CAM accept or maintain custody of a Client’s funds or securities, except for the limited authority as outlined in Item 15 – Custody. All Clients assets will be managed within the designated account[s] at the Custodian, pursuant to the terms of the advisory agreement. Please see Item 12 – Brokerage Practices. Retirement Accounts – When deemed to be in the Client’s best interest, the Advisor will recommend that a Client take a distribution from an ERISA sponsored plan or to rollover the assets to an Individual Retirement Account (“IRA”), or recommend a similar transaction including rollovers from one ERISA sponsored Plan to another, one IRA to another ORA, or from one type of account to another account (e.g. commission based

account to fee based account). In such instances, the Advisor will serve as an investment fiduciary as that term is defined under The Employment Retirement Income Security Act of 1974 (ERISA) and /or the Internal Revenue Code (“IRC”), as applicable, which are laws governing retirement accounts. Such a recommendation creates a conflict of interest if the Advisor will earn a new (or increase its current) advisor fee as a result of the transaction. No client is under any obligation to roll over a retirement account to an account managed by the Advisor. Financial Planning Services CAM typically provides a variety of financial planning and consulting services to Clients as part of their overall wealth management engagement. Financial planning is also offered as a stand- alone service. Services are offered in several areas of a Client’s financial situation, depending on their goals and objectives. Generally, such financial planning services involve preparing a formal financial plan or rendering a specific financial consultation based on the Client’s financial goals and objectives. This planning or consulting may encompass one or more areas of need, including but not limited to, investment planning, retirement planning, personal savings, education savings, insurance needs and other areas of a Client’s financial situation. A financial plan developed for, or financial consultation rendered to the Client will usually include general recommendations for a course of activity or specific actions to be taken by the Client. For example, recommendations may be made that the Client start or revise their investment programs, commence, or alter retirement savings, establish education savings and/or charitable giving programs. CAM may also refer Clients to an accountant, attorney, or other specialists, as appropriate for their unique situation. For certain financial planning engagements, the Advisor will provide a written summary of the Client’s financial situation, observations, and recommendations. For consulting or ad-hoc engagements, the Advisor may not provide a written summary. Financial planning and consulting recommendations pose a conflict between the interests of the Advisor and the interests of the Client. For example, the Advisor has an incentive to recommend that Clients engage the Advisor for investment management services or to increase the level of investment assets with the Advisor, as it would increase the advisory fees paid to the Advisor. Clients are not obligated to implement any recommendations made by the Advisor or maintain an ongoing relationship with the Advisor. If the Client elects to act on any of the recommendations made by the Advisor, the Client is under no obligation to implement the transaction through the Advisor. C. Client Account Management Prior to engaging CAM to provide investment advisory services, each Client is required to enter into an agreement with the Advisor to define the terms, conditions, authority and responsibilities of the Advisor and the Client. These services may include:
• Establishing an Investment Strategy – CAM, in connection with the Client, will develop a strategy that seeks to achieve the Client’s goals and objectives.
• Asset Allocation – CAM will develop a strategic asset allocation that is targeted to meet the investment objectives, time horizon, financial situation and tolerance for risk for each Client.
• Portfolio Construction – CAM will develop a portfolio for the Client that is intended to meet the stated goals and objectives of the Client.
• Investment Management and Supervision – CAM will provide investment management and ongoing oversight of the Client’s investment portfolio. D. Wrap Fee Programs CAM does not manage or place Client assets into a wrap fee program. Investment management services are provided directly by CAM. E.
