Item 5. Fees and Compensation
Wealth Management and Discretionary Investment Management Services
The fees charged for discretionary investment management services are charged as a percentage of
assets under management, as set forth in the investment advisory agreement between the client and
One Charles, and generally depend on the type of assets held by the client. The advisory fee percentage
charged to a client may be up to 1.4% on an annual basis. Fees for discretionary investment
management services are deducted directly from client accounts quarterly, in advance, and are based
on the fair market value of the client’s portfolio as of the last business day of the previous quarter as
provided to us by third-party sources, such as pricing services, custodians, fund administrators, and
client provided sources. If third party sources are not available, as may be the case for certain illiquid
holdings, One Charles’ Investment Committee will determine a fair value for billing purposes or
otherwise value in accordance with the terms of a client’s advisory agreement – and if unable to
determine a fair value will not include the holding for purposes of the fee billing calculation. In certain
instances, clients may compensate One Charles directly where the discretionary assets are held away
from the custodian for the client’s account.
Clients receiving investment management services will be responsible for all brokerage fees and other
transaction costs, and custodial fees and expenses. In addition, clients will be responsible for additional
fees and expenses incurred when investing their assets, such as fees charged by independent
managers, mutual fund fees and expenses, ETF expenses, trade away fees for transactions executed
away from the account custodian, mark-ups and mark-downs embedded in fixed income transactions,
and miscellaneous items such as transfer taxes, odd lot differentials, exchange fees, interest charges,
American Depository Receipt agency processing fees, trustee fees, and any charges, taxes or other fees
mandated by any federal, state or other applicable law or otherwise agreed to with regard to client
accounts.

The fee for investment management services does vary among clients, depending upon various
objective and subjective factors; such as the amount of the client’s assets, the complexity of the
engagement, and the level and scope of the overall investment advisory and/or consulting services to
be rendered. As a result of these factors, these services to be provided by One Charles to any particular
client could be available from other advisers at lower or higher fees.
Limited-Scope Financial Planning and Consulting Services
Fees for limited scope, non-discretionary financial planning and other services may be charged on an
hourly or fixed fee basis. These fees are negotiable, depending on the nature and complexity of the
client’s circumstances, as well as the individual involved in the planning process and once
determined, are set forth in the client agreement.
Retirement Plan Consulting Fees
Fees for Plan advisory services and Plan consulting services are negotiated prior to the signing of an
agreement with the specific Plan client. The fees for Plan advisory services and Plan consulting
services may be a flat fee, a project or an asset-based fee expressed as a percentage of total Plan
client assets. The fee for these services does vary among clients, depending upon various objective
and subjective factors; such as the amount of the Plan client’s assets, the complexity of the
engagement, and the level and scope of the overall investment advisory and/or consulting services
to be rendered. As a result of these factors, these services to be provided by One Charles to any
particular Plan client could be available from other advisers at lower or higher fees.
ERISA Disclosure for Retirement Planning
When One Charles provides investment advice to you regarding your retirement plan account or
individual retirement account, One Charles is 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. The way One Charles makes money creates some conflicts with your
interests, so One Charles operates under a special rule that requires One Charles to act in your best
interest and not put our interest ahead of yours.
Flat Fees and Project Fees
To the extent so engaged by a Plan client, One Charles may charge a flat fee or project fee for
investment advisory and/or consultation services. Fixed fees are negotiable, but generally range from
One Thousand Dollars ($1,000) to Five Thousand Dollars ($5,000) on an annual basis, depending upon
the level and scope of the services required. Flat fee(s) will be charged and billed to a Plan Client
quarterly in arrears unless otherwise noted, upon the signing of an agreement by the Plan Client.
Occasionally advisory services will be quoted on an hourly or per project basis. Alternatively, One
Charles may charge a one-time, project-based fee which may be quoted on an hourly or per project
basis. Such fees may be invoiced to the third-party administrator, recordkeeper, or custodian, or the
sponsor at the Plan Client's instruction.
