REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders of Monongahela All Cap Value Fund and Board of Trustees of Forum Funds
In planning and performing our audit of the financial statements of Forum Funds comprising
Monongahela All Cap Value Fund (the “Fund”) as of and for the year ended April 30, 2024, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), we considered the Fund’s internal control over
financial reporting, including controls over safeguarding securities, as a basis for designing our auditing procedures for the purpose of expressing our opinion on the financial statements and to comply with the requirements of Form N‐CEN, but not
for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.
The management of the Fund is responsible for establishing and maintaining
effective internal control over financial reporting. In fulfilling this responsibility, estimates and judgments by management are required to assess the expected benefits and related costs of controls. A fund’s internal control over financial
reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles (GAAP). A
fund’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
fund; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the fund are being made only in accordance with
authorizations of management and trustees of the fund; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of a fund’s assets that could have a material effect on the financial
statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or
detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.
A deficiency in internal control over financial reporting exists when the
design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A material weakness is a deficiency, or combination of
deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Fund’s annual or interim financial statements will not be prevented or detected on a timely basis.
Our consideration of the Fund’s internal control over financial reporting
was for the limited purpose described in the first paragraph and would not necessarily disclose all deficiencies in internal control that might be material weaknesses under standards established by the PCAOB. However, we noted no deficiencies in the
Fund’s internal control over financial reporting and its operation, including controls over safeguarding securities, that we consider to be a material weakness as defined above as of April 30, 2024.
This report is intended solely for the information and use of management and the Board of
Trustees of the Fund and the Securities and Exchange Commission and is not intended to be and should not be used by anyone other than these specified parties.
